Description

Technical Field

[0001] The present invention relates to a seismic isolation bearing with a vibration energy recovery function, belonging to the technical fields of seismic resistance and energy-saving buildings. Background Art

[0002] A seismic isolation bearing refers to a supporting device set up to meet the seismic isolation requirements of a structure. An isolation layer is added between the superstructure and the foundation, and a rubber seismic isolation bearing is installed to achieve a soft connection with the ground. Through such technology, about 80% of the seismic energy can be offset. For example, a laminated rubber bearing (or seismic isolation rubber bearing, sandwich rubber pad, etc.) is a structural member with a relatively small horizontal stiffness and a relatively large vertical stiffness. It can bear a large horizontal deformation while stably supporting the upper load, thereby extending the natural vibration period of the structural system and reducing the transmission of seismic energy to the superstructure.

[0003] The existing seismic isolation bearing technology, although it can effectively attenuate the transmission of horizontal and vertical vibrations, still has the following significant deficiencies:

[0004] Firstly, during the seismic isolation process, heat accumulation will occur due to frequent deformation displacement or friction of components, resulting in the degradation of the performance of the seismic isolation material, and further affecting the long-term stability and seismic isolation efficiency of the bearing.

[0005] Secondly, the existing technology does not effectively recover the mechanical energy and thermal energy generated during the vibration process, causing waste of energy resources. Especially in large-scale projects such as bridges, the cumulative effect of such energy losses is significant.

[0006] Therefore, there is an urgent need for a device that can both optimize the seismic isolation performance and achieve vibration energy recovery to solve the dual problems of thermal management failure and low energy utilization rate. Summary of the Invention

[0007] Objective: To overcome the deficiencies in the existing technology, the present invention provides a seismic isolation bearing with a vibration energy recovery function.

[0008] Technical Solution: To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0009] A seismic isolation bearing with a vibration energy recovery function includes: an upper support plate and a lower support plate. A collar is provided at the bottom of the upper support plate, and a hollow ring is provided at the top of the lower support plate. A pressing column is sleeved inside the collar, and a pushing plate is provided at the bottom of the pressing column.

[0010] A ring sleeve is sleeved inside the hollow ring. A plurality of mounting blocks are provided inside the ring sleeve. A piezoelectric material is provided at the bottom of the mounting block. An airbag is provided on the piezoelectric material, and a pressing block is provided above the airbag.

[0011] The upper edge of the pushing plate is clamped to the inner wall edge of the top opening of the annular sleeve, and the bottom of the pushing plate is in contact with the top of the extrusion block.

[0012] Optionally, the upper support plate and the lower support plate are rotatably connected on both sides through a support mechanism.

[0013] Optionally, an elastic pad is provided at the top of the pressing column.

[0014] Optionally, an air inlet pipe and an exhaust pipe are provided on the airbag. The end of the air inlet pipe is connected to the air inlet pipeline extending into the mounting block. A one-way valve is provided on the exhaust pipe. The airbag is also connected to one end of the connecting frame, and the other end of the connecting frame is connected to the moving plate. A through groove matching with the moving plate is provided on the mounting block. An exhaust groove is provided on the annular sleeve. A conductor is provided inside the hollow ring. An air outlet pipeline is also provided on the vibration isolation support.

[0015] Optionally, a connecting rod is further provided on the moving plate, and an arc-shaped plate matching with the exhaust groove is connected to the end of the connecting rod.

[0016] Optionally, a sealing ring is provided at the top of the pushing plate.

[0017] Optionally, a sealing ring is provided at the top of the annular sleeve.

[0018] Optionally, an arc-shaped plate groove is provided on the inner side wall of the hollow ring.

[0019] Optionally, threaded holes are provided on both the upper support plate and the lower support plate.

[0020] Optionally, an energy storage box is further included, and the piezoelectric material and the conductor are connected to the energy storage box through cables.

[0021] Beneficial effects: A vibration isolation support with a vibration energy recovery function provided by the present invention, when the vibration isolation support is impacted, the pressing column drives the extrusion block to slide relatively, causing the airbag to deform, so that the airbag absorbs the impact force and reduces the impact on the vibration isolation support. And when the airbag deforms, the force generated by the deformation of the airbag acts on the piezoelectric material. Through the pressure, the piezoelectric material is subjected to mechanical stress and generates a potential difference, thereby converting the force received by the vibration isolation support into electric energy. Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Through the mutual cooperation of structures such as the recycling mechanism and the heat energy recycling mechanism, when the shock isolation bearing is impacted, the abutting column drives the extrusion block to slide inside the mounting block, causing the airbag to deform. As a result, the airbag absorbs the impact force, reducing the impact on the shock isolation bearing. Moreover, when the airbag deforms, the force generated by the deformation of the airbag acts on the piezoelectric material. Due to the pressure, the piezoelectric material is subjected to mechanical stress and generates a potential difference, thereby converting the force received by the shock isolation bearing into electrical energy, and storing the electrical energy through the energy storage box, achieving the effect of recycling vibration energy.

[0023] 2. Through the mutual cooperation of structures such as the heat energy recycling mechanism, when the pushing plate and the extrusion block slide relative to each other, friction generates heat. Due to the setting that the moving plate no longer seals the through groove, the heat is discharged into the interior of the annular sleeve through the through groove, and the gas discharged from the airbag drives the heat to be discharged more quickly. At the same time, the moving plate drives the arc plate to move, causing the exhaust groove to discharge the heat into the interior of the hollow ring, heating the corresponding electrical conductor. When the temperatures of two different electrical conductors are different, a voltage difference is generated between them, thereby converting heat energy into electrical energy, and storing the electrical energy through the energy storage box.

Detailed implementation mode

[0032] The following combines the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0033] The following further illustrates the present invention with specific embodiments.

[0034] Embodiment 1:

[0035] This embodiment introduces a seismic isolation bearing with vibration energy recovery function, as Figures 1 to 7 shown, including: an upper support plate 1 and a lower support plate 16. A collar 19 is provided at the bottom of the upper support plate 1, and a hollow ring 12 is provided at the top of the lower support plate 16. A pressing column 20 is sleeved in the collar 19, and a pushing plate 21 is provided at the bottom of the pressing column 20.

[0036] An annular sleeve 2 is sleeved in the hollow ring 12. A plurality of mounting blocks 3 are provided in the annular sleeve 2. A piezoelectric material 4 is provided at the bottom of the mounting block 3. An airbag 5 is provided on the piezoelectric material 4, and an extrusion block 22 is provided above the airbag 5.

[0037] The upper edge of the pushing plate 21 is clamped on the inner wall edge of the top opening of the annular sleeve 2, and the bottom of the pushing plate 21 is in contact with the top of the extrusion block 22. This embodiment is used to generate a current by pressing the upper support plate 1 and the lower support plate 16 against each other, causing the pressing column 20 and the pushing plate 21 movably connected between the inner wall of the collar 19 and the top of the extrusion block 22 to slide, and applying the downward pressure to the piezoelectric material 4 through the extrusion block 22 and the airbag 5.

[0038] Further, in one embodiment, the two sides of the upper support plate 1 and the lower support plate 16 are rotatably connected through a support mechanism. This embodiment is used to realize the horizontal movement of the upper support plate 1 and the lower support plate 16 under certain constraints.

[0039] Further, in one embodiment, an elastic pad is provided on the top of the pressing column 20. This embodiment is used to buffer the acting force between the pressing column 20 and the inner wall of the collar 19.

[0040] Further, in one embodiment, an air inlet pipe 23 and an exhaust pipe 24 are provided on the airbag 5. The end of the air inlet pipe 23 is connected to an air inlet pipeline extending into the mounting block 3. A one-way valve 25 is provided on the exhaust pipe 24. One end of the airbag 5 is also connected to one end of a connecting frame 6, and the other end of the connecting frame 6 is connected to a moving plate 7. A through groove 8 matching the moving plate 7 is provided on the mounting block 3. An exhaust groove 11 is provided on the annular sleeve 2. A conductor 13 is provided in the hollow ring 12. An air outlet pipeline 26 is also provided on the hollow ring 12. This embodiment is used to add an air inlet pipe 23 and an exhaust pipe 24 to the airbag 5. When the airbag 5 is squeezed, a flowing medium is provided to the airbag 5 through the pipeline, so that while the airbag 5 maintains a certain rigid deformation, the flowing medium is discharged through the exhaust pipe 24 provided in the mounting block 3, causing the flowing medium in the closed space of the entire push plate 21, annular sleeve 2, and hollow ring 12 to start circulating from the inside to the outside. The flowing medium in the mounting block 3 is heated by the heat conducted by the extrusion block 22 through friction and its temperature rises. At the same time, the airbag 5 expands outward when squeezed, pushing the moving plate 7 connected to the airbag 5 outward. The moving plate 7 is pushed out from the engaged through groove 8, and the flowing medium in the mounting block 3 flows out and enters the hollow ring 12 through the exhaust groove 11 on the annular sleeve 2, where it exchanges heat with the conductor 13 to generate an electric current.

[0041] Further, in one embodiment, a connecting rod 9 is also provided on the moving plate 7, and an arc-shaped plate 10 matching the exhaust groove 11 is connected to the end of the connecting rod 9. This embodiment is used to clamp the arc-shaped plate 10 on the exhaust groove 11. When the moving plate 7 is pushed out, the arc-shaped plate 10 is synchronously pushed out from the exhaust groove 11, and the flowing medium increases its flow rate through the gap between the arc-shaped plate 10 and the exhaust groove 11, accelerating the heat exchange efficiency.

[0042] Further, in one embodiment, a sealing ring is provided on the top of the push plate 21. This embodiment is used to improve the sealing of the connection between the top of the push plate 21 and the inner wall of the top of the annular sleeve 2.

[0043] Further, in one embodiment, a sealing ring is provided on the top of the annular sleeve 2. This embodiment is used to improve the sealing of the connection between the top of the annular sleeve 2 and the inner wall of the top of the hollow ring 12.

[0044] Further, in one embodiment, an arc-shaped plate groove 14 is provided on the inner side wall of the hollow ring 12. This embodiment is used to cooperate with the extending stroke of the arc-shaped plate 10 without increasing the size of the hollow ring.

[0045] Further, in one embodiment, the support mechanism includes a rotating plate, and both ends of the rotating plate are rotatably connected to the sides of the upper support plate 1 and the lower support plate 16 through bolts respectively.

[0046] Further, in one embodiment, threaded holes 17 are provided on both the upper support plate 1 and the lower support plate 16. This embodiment is used to connect the seismic isolation bearing to other components.

[0047] Further, in one embodiment, it further includes an energy storage box 18, and the piezoelectric material 4 and the electrical conductor 13 are connected to the energy storage box 18 through cables. This embodiment is used to enable the current generated by the piezoelectric material 4 and the electrical conductor 13 to be transmitted to the energy storage box 18 through the cables, and the energy storage box 18 realizes the functions of current conversion and current storage.

[0048] Embodiment 2:

[0049] This embodiment introduces an embodiment of a seismic isolation bearing with a vibration energy recovery function, specifically including: an upper support plate 1, a lower support plate 16, and both sides of the upper support plate 1 and the lower support plate 16 are rotatably connected through a support mechanism. It is used to restrict the horizontal movement of the upper support plate 1 and the lower support plate 16.

[0050] The support mechanism includes four rotating plates 15, and the four rotating plates 15 are symmetrically arranged on both sides of the upper support plate 1 and the lower support plate 16 respectively. One end of the rotating plate 15 is rotatably connected to the upper support plate 1 through a pin shaft, and the other end of the rotating plate 15 is rotatably connected to the lower support plate 16 through a pin shaft.

[0051] Threaded holes 17 are also provided at the four corners on the surfaces of the upper support plate 1 and the lower support plate 16. Among them, connecting bolts are threadedly connected inside the four threaded holes 17, and are used to complete the connection of the upper support plate 1, the lower support plate 16 and other components through the mutual cooperation of the threaded holes 17 and the connecting bolts.

[0052] A tightening mechanism is installed on the lower surface of the upper support plate 1. The tightening mechanism includes a collar 19 fixedly connected to the lower surface of the upper support plate 1. A tightening column 20 is slidably connected inside the collar 19. Elastic pads in contact with the collar 19 are fixedly connected in an annular array on the upper surface of the tightening column 20. A pushing plate 21 is fixedly connected to the lower surface of the tightening column 20. Extrusion blocks 22 corresponding to a plurality of air bags 5 are arranged in a rectangular array on the lower surface of the pushing plate 21. A recovery mechanism is installed on the upper surface of the lower support plate 16. The recovery mechanism includes an annular sleeve 2 installed on the upper surface of the lower support plate 16. The annular sleeve 2 is fixedly connected to the middle of the upper surface of the lower support plate 16. Installation blocks 3 are fixedly connected in a rectangular array inside the annular sleeve 2. Air bags 5 are arranged inside the installation blocks 3. Through the arrangement of a plurality of installation blocks 3, a plurality of air bags 5 can be simultaneously squeezed and deformed by the corresponding extrusion blocks 22, so as to disperse and absorb the impact force, and improve the performance of the seismic isolation bearing in absorbing the impact force.

[0053] A piezoelectric material 4 is fixedly connected to the inner bottom wall of the mounting block 3, and an airbag 5 is fixedly attached to the upper surface of the piezoelectric material 4. When the airbag 5 deforms, the airbag 5 applies a pressure to the piezoelectric material 4, causing the piezoelectric material 4 to be subjected to mechanical stress and generate an electric potential difference. Then, through the setting of a rectifier bridge, the converted electrical energy is converted from alternating current to direct current.

[0054] When the shock isolation bearing is subjected to an impact force, the upper support plate 1 drives the collar 19 to slide relative to the abutting column 20, so that the abutting column 20 drives the push plate 21 to slide inside the annular sleeve 2, and the extrusion block 22 slides inside the mounting block 3, squeezing the airbag 5, causing the airbag 5 to deform. Through the buffering of the airbag 5, the impact force is absorbed, reducing the impact on the shock isolation bearing.

[0055] An air inlet pipe 23 and an exhaust pipe 24 communicating with the airbag 5 are respectively fixedly connected to both sides of the surface of the airbag 5. The air inlet pipe 23 is also connected through an air inlet pipeline extending into the mounting block 3. Through the settings of the air inlet pipe 23 and the exhaust pipe 24, when the airbag 5 deforms, the internal flowing medium, such as air, is discharged through the exhaust pipe 24. When the airbag 5 resets, air is inhaled into the airbag 5 through the air inlet pipeline and the air inlet pipe 23. Check valves 25 are fixedly connected to the interiors of both the air inlet pipe 23 and the exhaust pipe 24. Through the setting of the check valves 25, when the exhaust pipe 24 discharges the air in the airbag 5, the air inside the mounting block 3 will not enter the interior of the airbag 5 through the air inlet pipe 23. When the air inlet pipe 23 inhales air to reset the airbag 5, the air inside the mounting block 3 will not enter the interior of the airbag 5 through the exhaust pipe 24. Additionally, an air outlet pipeline 26 communicating with the outside is provided on the hollow ring 12 (certainly, the air outlet pipeline 26 can also be provided at the bottom of the lower support plate 16 communicating with the hollow ring 12). The air outlet pipeline is connected to a flowing medium box body, and a pump is connected to the flowing medium box body. The air inlet pipeline connected to the pump outlet forms a circulating loop for the flowing medium.

[0056] The airbag 5 is fixedly connected inside the mounting block 3, and the extrusion block 22 corresponds to the mounting block 3. Connecting frames 6 are fixedly connected to the surface of the airbag 5 in an annular array. The other side of the connecting frame 6 is fixedly connected to a moving plate 7. A plurality of moving plates 7 are correspondingly arranged. Through the corresponding arrangement of the moving plates 7, when the plurality of moving plates 7 move, they will not fit together, avoiding mutual movement obstruction among the plurality of moving plates 7. Additionally, since the airbag in the present invention is used in a shock isolation bearing corresponding to a large component, the size and material of the airbag can support the connection of the connecting frame 6 to the airbag 5 through adhesion or by setting the structure of a mounting seat.

[0057] The moving plate 7 is slidably connected to the inside of the mounting block 3. Through grooves 8 corresponding to the moving plate 7 one by one are formed on the surface of the mounting block 3 in an annular array. When the extrusion block 22 and the pushing plate 21 rub against each other, heat will be generated. At the same time, when the airbag 5 deforms, the connecting frame 6 is caused to push the moving plate 7 to move, so that the moving plate 7 no longer blocks the through groove 8. Thus, the gas discharged from the airbag 5 drives the heat to enter the inside of the annular sleeve 2 through the through groove 8 to dissipate the heat inside the mounting block 3.

[0058] Wherein, one side of each of the six moving plates 7 is fixedly connected with a connecting rod 9. One end of the connecting rod 9 is fixedly connected with an arc plate 10. Exhaust grooves 11 corresponding to the arc plate 10 one by one are formed on the surface of the annular sleeve 2 in an annular array. A thermal energy recovery mechanism is installed on the outer surface of the annular sleeve 2. The thermal energy recovery mechanism includes a hollow ring 12 fixedly connected to the surface of the annular sleeve 2. The moving plate 7 drives the connecting rod 9 to move, so that the arc plate 10 no longer limits the exhaust groove 11. Thus, the heat enters the inside of the hollow ring 12 through the arc plate groove 14.

[0059] Two corresponding conductors 13 are fixedly connected inside the hollow ring 12. Arc plate grooves 14 corresponding to the exhaust grooves 11 are formed on the inner arc surface of the hollow ring 12 in an annular array. The corresponding conductors 13 are heated by the heat entering the hollow ring 12, so that the temperatures of the two different conductors 13 are different, and a voltage difference is generated between them, so that the thermal energy is converted into electrical energy.

[0060] A storage box 18 corresponding to the piezoelectric material 4 and the conductor 13 is fixedly connected to the lower surface of the lower support plate 16. An existing rectifier bridge is provided inside the storage box 18 and corresponds to the piezoelectric material 4. A capacitor is provided inside the storage box 18. The electrical energy converted from the thermal energy and the electrical energy converted from the pressure are stored in the capacitor inside the storage box 18 to achieve the effect of vibration energy recovery.

[0061] Embodiment 3:

[0062] This embodiment introduces an engineering application of a seismic isolation bearing with a vibration energy recovery function. Taking the bridge application scenario as an example, when the seismic isolation bearing with a vibration energy recovery function of the present invention is used, it is installed between the bridge structure and the bridge pier, and is connected and fixed to the upper and lower structures through anchor bolts or special connectors. At the same time, the intake pipeline extending into the mounting block 3 is connected to a pump, and the outlet pipeline provided on the hollow ring 12 is connected to a flowing medium box.

[0063] When the seismic isolation bearing of the present invention is manufactured, a hollow ring 12 is fixed to the top of the lower support plate 16. A ring sleeve 2 is sleeved on the hollow ring 12, and the bottom of the ring sleeve 2 is also fixed to the top of the lower support plate 16. The diameter of the ring sleeve 2 is smaller than the inner diameter of the hollow ring 12. The gap between the ring sleeve 2 and the hollow ring 12 is used to place the electric conductor 13 and ensure the stroke of the arc-shaped plate 10 extending. The height of the ring sleeve 2 matches the height of the inner wall at the top of the hollow ring 12 to ensure that the top of the ring sleeve 2 contacts the inner wall at the top of the hollow ring 12. To ensure the tightness therebetween, the tightness can be further enhanced by adding a sealing ring. The bottom of the mounting block 3 inside the ring sleeve 2 is fixedly connected to the top of the lower support plate 16. A piezoelectric material 4, an airbag 5, and a squeezing block 22 are sequentially arranged inside the mounting block 3. In addition, to ensure the tightness between the pushing plate 21 and the ring sleeve 2, the pushing plate 21 is sleeved on the top opening of the ring sleeve 2, and the diameter of the pushing plate 21 is larger than the diameter of the top opening of the ring sleeve 2. Supported by the squeezing block 22 at the bottom, the top of the pushing plate 21 is ensured to contact the inner wall at the top of the ring sleeve 2. To ensure the tightness therebetween, the tightness can be further enhanced by a sealing ring with vertical deformation provided at the top of the pushing plate 21, so that the pushing plate 21, the ring sleeve 2, the hollow ring 12, and the lower support plate 16 form a sealed space. A flowing medium can be set in this sealed space, which can be a gas or a liquid. The flowing medium is in the sealed space. The intake pipeline can extend into the lower support plate 16 from the bottom and extend into the mounting block 3, or can extend into the mounting block 3 through the side surfaces of the hollow ring 12 and the ring sleeve 2. The exhaust pipeline, the sealed space, the intake pipeline, the flowing medium box body, and the pump form a loop for the flowing medium to circulate.

[0064] In addition, the cable can enter the seismic isolation bearing along with the pipeline or through holes opened on the seismic isolation bearing, and is respectively connected to the piezoelectric material 14 and the electric conductor 13.

[0065] In this embodiment, the flowing medium is air. When the seismic isolation bearing is subjected to an impact force, the upper support plate 1 drives the collar 19 and the abutting column 20 to slide, so that the abutting column 20 drives the pushing plate 21 to slide inside the ring sleeve 2, and the squeezing block 22 slides inside the mounting block 3, squeezing the airbag 5, causing the airbag 5 to deform. Here, the deformation is mainly the expansion in all directions, and the displacement of the squeezing block in the vertical direction is very small, smaller than the deformation of the sealing ring on the top surface of the pushing plate 21. Thus, through the buffering of the airbag 5, the impact force is absorbed, reducing the impact on the seismic isolation bearing caused by the impact force. At the same time, when the airbag 5 deforms, the airbag 5 applies a pressure to the piezoelectric material 4, causing the piezoelectric material 4 to be subjected to mechanical stress and generate a potential difference. Then, through the setting of the rectifier bridge, the converted electric energy is converted from alternating current to direct current and stored in the capacitor inside the energy storage box 18, achieving the effect of recovering vibration energy;

[0066] Meanwhile, heat is generated due to the mutual friction between the pressing column 20 and the extrusion block 22. When the airbag 5 deforms, the connecting frame 6 is driven to push the moving plate 7 to move, so that the moving plate 7 no longer blocks the through groove 8. Thus, the gas discharged from the airbag 5 drives the heat to enter the inside of the annular sleeve 2 through the through groove 8 to dissipate the heat inside the mounting block 3. At the same time, the moving plate 7 drives the connecting rod 9 to move, so that the arc-shaped plate 10 no longer limits the exhaust groove 11. Thus, the heat enters the inside of the hollow ring 12 through the arc-shaped plate groove 14 to heat the corresponding electrical conductor 13. As a result, the temperatures of the two different electrical conductors 13 are different, and a voltage difference is generated between them. Thus, thermal energy is converted into electrical energy, and the electrical energy is stored by the capacitor inside the energy storage box 18. In addition, the gas entering the hollow ring 12 flows out from the air outlet pipeline, causing the gas in the closed space to circulate and accelerating the heat transfer. The deformed airbag 5 is reset through a pump and an air inlet pipeline to ensure the reuse of the device.

[0067] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
