Description

FIELD OF THE INVENTION

The background of the invention is in the fields of developing a mechatronic control and device of earthquake which is a three-phase damper in a two-layer foundation, with dampers placed under the pressure of hydraulic fluid and gas between two layers of the foundation, one under the structure and the other on the ground or piles. This invention's field can be searched with International patent codes (IPC) F16F9/14, F16F9/22, F16F11/00, F16F13/00 and F16F15/00 in various patent databases.

BACKGROUND OF THE INVENTION

The EP2217829BI patent with the title of “Viscose torsional vibration damper having at least one pulley decoupled from the vibrations of a crankshaft” relates to a viscose torsional vibration damper having at least one pulley (5a) that is decoupled from the vibrations of a crankshaft, wherein the vibration damper comprises a damper ring (2) that can be rotated in a damper housing (1) filled with a viscous medium relative thereto, and wherein bearings (40, 41, 42) and elastic couplings for the relative rotatable and elastic support of the pulley (5a) or pulleys (5a, 5b) in the circumferential direction with respect to the damper housing (1) are provided. At least one pulley (5a) is arranged axially adjacent to the damper housing (1). A carrier part (20) is provided on the damper housing for supporting said pulley (5a) and comprises an axial protrusion (4), a flange (21) directed radially outward on the end facing away from the damper housing (1), and a ring section (22) directly connecting thereon and extending in the direction of the damper housing (1). A chamber (23) is formed by the axial protrusion (4), the flange (21), and the ring section (22), the coupling elements being arranged inside said chamber. The pulley (5a) axially adjacent to the damper housing (1) is supported on the carrier part (20) and is coupled in a rotationally elastic manner via the coupling elements arranged in the chamber (23) relative to the damper housing (1) in the circumferential direction like all other pulleys (5b). By comparing the available maps and examining this invention, it is easy to understand that the above invention, instead of using a limiter of linear movement by an incompressible fluid, uses a cable and the rotational movement that is limited with the help of this fluid does the act of wasting energy.

The U.S. Pat. No. 9,638,279B2 patent with the title of “Damper and handle device having the same” provides a damper a damper including: a housing; a rotor; and a sealing member. The housing includes outer and inner cylinder portions to define a filling space portion there between for filling with a viscose fluid. The rotor includes a head portion and a cylinder portion extended downwardly therefrom so as to be inserted into the filling space portion. The sealing member seals the filling space portion. The rotor further includes axially-extending first and second groove portions provided on outer and inner peripheral surfaces of the cylinder portion near the bottom portion thereof. At least one of the first groove portions includes a communicating portion which communicates the inside and the outside of the rotor, and the second groove portion is apart from the communicating portion in a circumferential direction. This invention, disclosed by Japanese engineers, is a type of cylindrical damper that uses the circulation of two parts inside each other and pumping under liquid pressure to waste the received viscous energy and prevents the deformation of the main elements of the structure under the influence of earthquake force. Due to the relative deficiency of the existing summary, a part of the claim is given for better understanding. Obviously, this invention has no overlaps with the claims of the presented invention.

The KR20070091265A patent with the title of “Viscose damper comprising a sheet metal housing” relates to a viscose damper comprising a sheet metal housing and a cover for closing the housing, which also consists of sheet metal. A flywheel ring is mounted in a fluid in a floating manner inside the housing, and the viscose damper comprises a bearing borehole. Said viscose damper is characterized in that an additional centering possibility for the viscose damper is provided on the cover and/or on the housing, in the form of centering projections arranged on a common periphery. In this way, the viscose damper can be additionally or independently centered on a larger diameter than that of the bearing borehole. Other centering projections can be arranged on different peripheries. This invention is different from our invention both in terms of its location and the type and method of controlling and applying the limit of two pieces.

The US20040241015A1 patent with the title of “Turbocharger comprising a torsional-vibration damper” alludes to an exhaust-gas turbocharger, which is operated by the exhaust gas of a combustion engine and is equipped with a rotor unit that rotates at high-speed. Said rotor unit comprises a turbocharger shaft, a turbine wheel that is rotationally fixed to the shaft, in addition to a compressor wheel that is rotationally fixed to the shaft. To increase the operational reliability of said turbocharger, a torsional-vibration damper is located on the turbocharger shaft. The torsional-vibration damper reduces torsional-vibration stresses that arise in the shaft, which are caused by motor pulsations of a higher order of the combustion engine. By examining the drawings provided, it is possible to see that the only similarity of this part, which is designed for the car, is the use of the viscosity property of the hydraulic fluid. It has only a dynamic application and is effective in transmitting the circulation force, while the use of the viscous property of the liquid to dissipate the force and maintain the structure statically is claimed in the invention.

The TW201942494A patent with the title of “Fluid viscous damper” points out to a fluid viscous damper, comprising a cylinder, a piston assembly, and an accumulation unit. The cylinder has a first chamber filled with fluid. The piston assembly has a piston disposed in the cylinder and dividing the chamber into two rooms in communication with one another. The accumulation unit has a secondary chamber filled with fluid for making up any leakage of the fluid in the first chamber to maintain the oil pressure in the first chamber in consistency.

The JPS60146930A patent with the title of “Fluid viscous damper” relates to the presentation of a convenient damper utilized particularly for small size machines and tools such as measuring devices, office machines, etc., by arranging a permanent magnet outside a sealing vessel sealed with viscous fluid and a magnetic material piece in the inside so as to both eliminate a leak of the viscous fluid and obtain a desired damping characteristic. This invention claimed to be constituted from a sealing vessel 2, having a cylindrical shape, is sealed in the inside with a ball 3 being a magnetic material piece and silicone oil 4 being viscous fluid, being completely sealed. The sealing vessel 2 arranges outside in the vicinity of its central part a permanent magnet 6 having N and S poles, and the ball 3 being the magnetic material piece is placed in a stationary condition by the permanent magnet 6. In this way, the silicone oil 4 being the viscous fluid is fluidized between the ball and an internal wall of the vessel 2, providing damping force by this fluidizing resistance.

The CN101514731A patent with the title of “Viscous fluid damper” relates to a viscous fluid damper with good performance, comprising a closed cylinder with end covers arranged on both ends, a piston positioned in the cylinder cavity and a piston rod connected with the piston; wherein, the cylinder is filled with viscous fluid or controlled fluid; the piston comprises fixed piston discs sheathed on and fixedly connected with the piston rod and full floating piston discs sliding relatively along the piston rod; the full floating piston discs are positioned among the fixed piston discs and are mutually connected by elastic connectors; throttle route ways are arranged between the external side walls of the fixed piston discs and the full floating piston discs and the internal side wall of the cylinder. The damper has two dependent control characteristics such as speed and displacement, can store and release energy in the process of vibration reduction, not only has certain real time tunability, but also has good controllability and reliability and can be universally suitable for vibration control of special structures such as automobiles, machinery, aviation, civil engineering and transmission line, etc.

The TR201204231A2 patent with the title of “Damper with viscous fluid” relates to a cylinder applied in said cylinder, which is filled with liquid fluid at both ends, which prevents the moving units such as doors, latches, drawers from closing fast and closing when stationary on fixed units, damping the closing force and slowing down at the moment of closing. a spindle, which is mounted on the end of the spindle, which acts on the spindle, which allows the liquid fluid to absorb the mixture and impacts; and a damper assembly comprising a valve which closes the piston holes due to the pressure difference in the cylinder caused by the linear movement of the shaft within the cylinder.—a conical piston of said piston and the holes for the passage of liquid fluid at the conical surface, the elastic resilient closures of said valve,—and centered in the cylinder under the valve, centered in the cylinder, moving in the middle for fluid passage through the shaft. and a second piston comprising at least one bore. In this invention, the field of application of which is defined in drawer doors, or considering the available summary, none of the claims of our original invention were present and there is only the movement of a piston in a highly concentrated liquid to prevent the shock when the door closes. It is clear from the description of this invention that its application and structure are very different from our claimed invention.

SUMMARY OF THE INVENTION

The mechatronic control of the earthquake by the three-phase damper in the two-layer foundation is a construction industry invention, particularly regarding earthquake resistance. One of the difficulties in constructing a structure in earthquake-prone locations is its resistance to various types of shocks induced by this wave and the resulting energy, which causes parts of the structure to break or collapse. Because of the static nature of the structure, there is a need to modify the situation during the earthquake, and we must waste the energy from the shear wave in the building. When the longitudinal waves approach, the sensors activate the dampers embedded in the foundation, preventing dramatic height change in relation to each other. Putting these sorts of dampers, which use gas, liquid, and solid reduces or eliminates the need for a shear wall and installing the damper in the structure.

DETAILED DESCRIPTION OF THE INVENTION

During an earthquake, a lot of energy is imposed on the structure, the amount of energy input depends on the periodicity of the structure and the ratio of the dominant period of the ground motion, and the amount of destruction depends on the amount of hysteresis energy absorbed under the inelastic forms of the structural members. Incoming energy appears in the structure in two forms, kinetic and potential, which must be absorbed or dissipated in some way. If there is no type of damping in the structure, the structure will continue to vibrate indefinitely, but practically due to the properties of the structure, there is some damping in the nature of the materials that make up its elements which causes the structure to react against vibration and reduce responses considering that the amount of inherent damping in the structures is very low, the depreciated energy is negligible in the range of elastic behavior of the structure.

During strong earthquakes, the structure faces large deformations after the limit of elastic behavior and remains stable only due to its inelastic displacement capability. This change of inelastic places causes plastic joints to be formed locally in some parts of the structure. As a result, a large amount of earthquake energy is consumed due to local damage in the lateral resistance system of the structure. A safer process should be considered for the design of very important buildings (in the 2800 standard division) and buildings that must provide services after an earthquake. In order to consume energy in a safe way with minimal damage to structural members, as well as to effectively reduce the responses of the structure, the energy input to the structure should be reduced or the amount of energy loss in it should be increased. Structural control is a strategy and a method that is very much considered in this field today.

Dampers can be mentioned as examples of seismic control systems. The problem that this invention attempts to solve is reducing the forces on the building caused by earthquakes without using dampers and shear walls in the structure itself, which is only in the foundation using mechatronic control dampers in three hybrid phases of gas, liquid, and solid according to their fluid properties. Another issue is maintaining the building's static state, which is in conflict with its dynamic change during an earthquake. The mechatronic controller solves this difficulty as well, and the above mechanical properties will arise at any time.

To address the present issues, a damper (1) with the ability to be installed on the main foundation was proposed. This damper (1) is made up of two pistons in two different environments that are linked together by a shaft (8). The pressure of the liquid (16) that enters and exits this chamber through the conduit controls the incompressible fluid piston (12), which is sealed by the rings (11) inside the piston (10). The weight of the structure transfers pressure from the upper side to the plate (17), which is held in place by screws that pass through the hole (18). The pneumatic piston (5) is encased in the cylinder (7), and it is pushed up by the air pressure force (6) or the inert gas. The pressure is transmitted by the cylinder (7) via the bases (13), and the compressible fluid enters through the inlet (14). The force produced by the movement of two pistons is transferred to the upper plate (2) by the metal cylinder (4), and it gets attached to the upper elements via holes (3).

In terms of absorbing and converting the force of an earthquake, the performance of this damper, which has two phases, liquid, and gas, can be compared to that of a car's spring and shock absorber since it functions like a spring during force absorption and gas fluid compression. It contracts and expands in an attempt to keep the structure intact; however, the incompressible fluid of the liquid, due to its high viscosity, slows down the movement of the damper (1) during an earthquake and prevents sudden and quick motions. It transforms incoming energy into thermal energy. The third phase, controller-blocker-solid, is controlled in two ways, which will be discussed further below. This sort of damper can be installed on all types of foundations. The damper (1) can be built in a strip foundation plan (19), which contains a single foundation (20), anchors (22), and base plates (21), which can be accomplished by placing it on the base plate (21) and using the bolt (31).

An appropriate connection can be created by utilizing the nuts (24) and inserting the bolt (18) into the hole (18). In a structure with a metal frame, the placement of proper beams (25) on the dampers (1) creates a proper connection between the plates (2) to other structural elements like columns (26) and prevents point settlement that causes wall failure. In this implementation, it is preferable to calculate and add the foundation depth to the buried damper height. The IPE beams connect the plates (2), and due to the greater distance between the two wings caused by the deformation of the iron beam, reinforced by metal plates (29) at both ends and the middle, creates maximum strength. The anchors (22) that connect the bases (20) in the strip foundation (19) are strengthened by ribbed round shafts (30) and are executed flush with the foundation (20).

We can see from the lowest layer of lean concrete (33) to a part of the column (26) formed of IPE in shear (27), which displays further details of the execution. Although chosen, the longitudinal bars (30) are intended, but the stirrups (32) are plain bars. To maintain the position and distance between the P plates (21), the cables under tension (37) are adjusted by the screw tensioners (36) and or bars (23) which are attached to the plate (22) with an additional connection (24) are utilized. The operation of these bars (23) is identical to that of thermal bars. Given various structures in the building, each with its own advantages, this form of damper (1) can be used in both concrete and metal structures.

This method can also be employed in concrete constructions to achieve this goal by placing a portion of the metal mold (30) on the plate (2) and firmly connecting it—for example, by welding—and constructing the rest of the building on it. As the calculations show, the dimensions of the concrete column are slightly greater than those of the metal columns. In addition, according to the structural experts, a metal connector or anchor (40) or putter may be used to connect the columns near the foundation. If this form of concrete structure is required, the waiting armatures (37) that are held in place by the stirrups (38) during anchor (40) implementation are put into the concrete after the anchor (40) is concreted. Molding can be done in one or more steps along the fixed metal mold (39).

The height of the metal mold (39) is at least 50% more than the mold's maximum cross-sectional size, so that tension caused by lateral forces can be transferred to the damper (1). We used shear (41) in the construction with the concrete frame to better demonstrate the details of the positioning of this damper (1). It is obvious from the name of this invention that an electronic controller (42) was envisaged to control the mechanical systems that depreciate the seismic force. By connecting to this controller, the sensors that notify the angle of the main beams (28) determine the smallest changes. The height is controlled by adjusting the hydraulic pressure in the damper (1). A hydraulic oil transmission pipe (45) connects each damper (1) to the central mechatronic controller (42). The central mechatronic controller (42) in this system processes input from sensors using electronic modules installed in the controller (48) and issues commands to the electromechanical parts.

The connector allows for electrical connections to the sensors and the urban power supply (47). This connector is meant to be located outside the device (42) so that we do not have to open the metal door for testing and troubleshooting. Input converters (46) are used to connect hydraulic fluid-containing pipelines (45) to the device (42). These converters are a type of connection with an internal thread that provides a sufficient connection to prevent hydraulic fluid leakage (16). A hydraulic pipe (45) is introduced into the device (45) from each damper (1) so that the movement of liquid between other dampers can be controlled when the building vibrates. We have a distinct situation with the compressed air transmission line (44) that connects to the device (42) via the inlet (49).

However, the air pressure at the inlet (49) is as high as the hydraulic liquid pressure (16) in the hydraulic pipes (45), but only one inlet is considered to transfer air for all dampers (1). When the air pressure drops, as indicated by the display (50)—barometer—some air is transferred from the tank (52) into the air pipes (44) to compensate for the pressure drop. Also, if the air pressure is too low and cannot be balanced by the air inside the tank, the air pump (53) kicks in and compensates for the volume loss. It should be observed that the air pressure in each damper is somewhat higher than the hydraulic fluid pressure, which can be returned to its previous position at the end of the earthquake due to its compressibility. Furthermore, an air tank (52) with proper size increases flexibility when dampers compress the air.

One of the issues with the operation of mechatronic equipment during natural disasters is a lack of sufficient electricity for operation. This invention resolves this problem by inserting the electrical energy storage source (60) under the air tank (52) for a suitable period of time. This rechargeable battery (60) was chosen with periodic testing to check its capacity loss due to the passage of time, and if it reaches the end of its useful life, it should be replaced. Its unusual design maximizes space, and it is feasible to provide sufficient voltage, amperage, and capacity by building and connecting numerous batteries in parallel. Low voltage is used to regulate this device so that even during floods, we have the least danger of damage due to the presence of resistance measures against water penetration in case of leakage and penetration.

The electric hydraulic pump (62) fills and pressurizes the hydraulic oil pressure storage tank (55) by pipe (54), which is still connected to the fluid path/pressure controllers (59) through the liquid conductor pipe (56). If the level/pressure of the hydraulic fluid in the tank (55) falls, the pump (62) adjusts fluid shortage by utilizing the oil sump (58). The oblique shape of the oil sump (58) towards the pump (62) permits an adequate amount of liquid surface to be available by the pump even with a large reduction in the volume of the liquid surface in the sump (58). This tank's (58) stable connection is achieved through the use of a flexible foundation (61).

Although the hydraulic liquid pressure and direction control valves (59) are shown to be integrated, each has its own function, and each is furnished with a unique hydraulic liquid pressure indication (57)—manometer. During an earthquake, however, the connection between them is established through the opening of electric valves or the pressure-induced rupture of the diaphragm, and it ensures the same related movements between the dampers, which means that when the level of one decrease, the level of the other increases by the same amount. There will be no dangerous failure due to foundation subsidence or bulging. The manometers (57), like the barometer (50), are designed to be somewhat higher in the valves (59) so that they can be seen readily when the metal protective cover is placed outside it.

The set of valves (59) includes a metal body that can bear hydraulic fluid pressure. Details are displayed using horizontal shear (63) and vertical shear (64). When the pipe (56) that connects the valves (59) to the hydraulic tank (55) becomes a bottleneck (65) upon entrance. This element reduces the probability of returning to the tank as a result of the earthquake while the dampers (1) exchange liquid, which balances the dampers (1). The liquid enters the general transfer channel (66) after passing the bottleneck area (65). This channel is regulated by individual valves (67) connected to each damper connection pipe (46). When the pump (62) supplies hydraulic pressure, all-electric valves (67) are open, and the liquid under pressure is delivered from the channel (66) to the dampers via an intermediary (68).

The connection pipe (69) connects the manometer (57), which indicates the pressure of each damper (1) to its conductor pipe (46). Two routes are considered inside each valve (67) to stop and open the movement of liquid. When electricity is applied to the coil (71) and a fixed metal part (72), and a moving metal part (76), the metal parts attract each other and overcome the force of the spring (73) and move towards each other, and the liquid conductor groove (77) is placed along the paths (75), and the liquid can reach from one damper to the channel (66) and other dampers. The electric solenoid (71) is connected to the body via the base (78). Any electronic system, like mechanical systems, can be found to have faults, and we require some form of backup in this gadget. We have a sort of port (69) locked in place by holders (70) when the solenoid valves (74) do not work due to the more accurate performance of mechanical systems.

This port (69) is actually a very thin metal plate that tears due to liquid pressure and allows liquid to be transferred in an emergency. It will be replaced after the earthquake by reviewing and testing this part in case of damage. Its repair and maintenance expenses will obviously be significantly less than the structural damage caused by non-functioning. As we all know, earthquake waves are divided into surface and internal waves, with the destructive wave being the S wave, also known as the shear waves, and causing the most damage. We use longitudinal P waves to detect the start of an earthquake, and when the command reaches the control module (48), the open command is provided to the solenoid valves (59), allowing fluid exchange between the dampers. When the S wave (81) travels beneath the structure, it is changed into two horizontal (83) and vertical (82) force components, the latter of which can be destructive, causing a part of the structure to break and shear.

In this situation, by compressing the first damper along the S wave (78), the hydraulic fluid will be released, and when the hydraulic fluid enters the other dampers (79) and (80), they will open as required while preventing the angle from altering or breaking. After the earthquake has ended, equilibrium is restored between dampers (1), and the structure is balanced in its location due to air pressure. The need for an electronic controller is obvious given the nature of the invention, which is a mechatronic system; in this invention, it is advised to employ a processor (85). This processor (85) is powered by a voltage regulator (79), which is fed by the connector (78).

The information is received by an LED (80) positioned at the output, which reveals the correctness of the feeding function with the help of the resistance (81) fitted to the regulator output voltage. Processor (85) receives data via connectors (83) and (84) with the help of input protection resistors (90). In fact, two ports A and B are allocated to sensor information input from outside the system, port C is available for connecting to the keyboard (87), and port D is available for connecting to the display (82). In addition, output F is used to provide commands to the operational amplifier. The amplifier's output (86) is transformed to an isolated output with proper amperage using relays (88), allowing it to control the electric valves (74).

The application of this invention is only in the construction industry and earthquake resistance. In structures where there is a possibility of destruction due to a strong earthquake despite the existence of a damper or shear wall, or in structures that are of high importance, such as a telecommunications building, or due to the type of architecture, there is no possibility of having a damper in the structure itself, this damping can be useful. In order to use the invention, after implementing the foundation, which may be single or strip or wide or piled, we install dampers on it and make mechanical and electrical connections after implementing the structure on it, we calibrate it by increasing the air pressure and hydraulic fluid and put it in a static state. At the time of the earthquake, the operation will be done automatically and after the end of the earthquake, the inspection and services will be done.

In this invention, by using changes in the foundation, design limitations in the structure have been removed, and the reduction in the cost of the structure will be more than the increase in the cost of the foundation, which is desirable in engineering economics. Also, due to the dynamic control of the height of the foundation, even in the case of point settlement due to the reduction of the density of the soil under the foundation, cracking and failure in the walls and structure will be prevented.

The device and mechatronic control of earthquake is a three-phase damper in a two-layer foundation, with dampers placed under the pressure of hydraulic fluid and gas between two layers of the foundation, one under the structure and the other on the ground or piles. When an earthquake happens, it is feasible to transport the incompressible fluid between the dampers to prevent shear force failure, and it is made up of the following major components.

a. Dampers that apply force on the upper layer's foundation under compressible and viscous fluid pressure.

b. Sensors for controlling the angle of any large beam or foundation, or anchor.

c. c. Mechatronic pressure controller and damper interconnection.

d. d. Modified foundation in two layers by placement beneath and top of the dampers.

e. e. Mechanical and electrical connections of the sensors and dampers to the central controller.

2. According to declaration 1, the damper device can absorb force and return with a controlled speed by utilizing two pressure forces of gas fluid and hydraulic liquid fluid.

3. According to declaration 2, the gas phase and liquid phase are used to maintain pressure and speed in the dampers between the two layers, and the solid diaphragm phase is employed in communication pipes to manage liquid exchange and, as a consequence, stability when no earthquake occurs.

4. According to declaration 2, the stability control method or entry into suspension during an earthquake via dampers connected to a mechatronic controller equipped with an acceleration and pressure sensor control processor is claimed.

5. According to claim 1, the method of increasing the height of other dampers as a result of compression of one damper is claimed in accordance with the law of mixed containers.

6. The use of an angle control sensor to warn or correct for leakage between foundations is claimed in declaration 1.

7. According to declaration 6, compensation of point settlement of the foundation caused by soil density reduction by dampers is intended to prevent failure in the construction.

8. The method of directing the commencement of an earthquake to the processor by sensing the pressure increase in a damper is claimed in declaration 1.

9. A mechatronic controller capable of maintaining stability in normal conditions and entering dynamic active control during an earthquake is claimed in declaration 1.

10. The employment of electric valves equipped with a compensator for the failure of the metal diaphragm is claimed in declaration 1.

11. Within the scope of the description and map of the declaration, declaration 10 claims a wholly mechanical suspension system independent of electronic devices capable of preserving the function in the event of a problem in the mechatronic controllers.

12. According to declaration 1, the foundation is divided into two levels, with the possibility of transferring structural force to the dampers and to the depth or surface of the ground in the lower layer of the dampers.
