Description

Technical Field

[0001] This invention relates to the field of building seismic equipment technology, and in particular to a high-energy-consuming viscous damping device. Background Technology

[0002] With the rapid advancement of global urbanization, the seismic performance design of buildings has received high attention, especially in earthquake-prone areas, where improving the seismic resistance of buildings is crucial for protecting people's lives and property.

[0003] Viscous dampers are made based on the principle that motion, especially when viscous liquids pass through a throttling orifice, generates throttling resistance. They are a type of damper that is related to the speed of piston movement and are widely used in high-rise buildings, bridges, and seismic retrofitting of building structures.

[0004] Viscous dampers commonly used in seismic-resistant building structures are piston-type, with the core components being a hydraulic cylinder and a piston. Their working principle involves the piston reciprocating within a cavity, squeezing the viscous damping fluid through tiny oil holes on the piston or the gap between the piston and the inner wall of the cylinder, converting absorbed energy into heat energy for dissipation. When subjected to significant energy, the piston moves rapidly within the cavity, and the rapid friction between the piston and the cylinder causes a rapid increase in internal temperature. As the temperature rises, the viscosity coefficient of the damping material decreases sharply, leading to unstable performance of the viscous damper. Especially at high speeds, its mechanical properties degrade significantly, and its energy dissipation capacity decreases drastically, affecting the damper's effectiveness. Furthermore, dampers are generally made of metal; when the internal temperature rises rapidly, the metal material undergoes creep at high temperatures, reducing its strength and making the damper prone to damage.

[0005] Therefore, it is necessary to provide a high-energy-consuming viscous damping device to solve the above-mentioned technical problems. Summary of the Invention

[0018] Compared with related technologies, the high-energy-consuming viscous damping device provided by the present invention has the following beneficial effects:

[0019] 1. This invention provides a high-energy-consuming viscous damping device. Through the arrangement of adjusting and cooling components, when swaying occurs, the reciprocating movement of the piston rod synchronously drives the two outer stabilizing rods to move. When the stabilizing rods move, they drive one end of the piston to move within the suction cylinder. When the piston moves backward, it draws liquid from inside the oil cylinder through the suction pipe, thus drawing the liquid into the suction cylinder. Meanwhile, liquid inside the oil reservoir on the other side is injected into the oil cylinder through a connecting pipe. When liquid is injected into the oil reservoir through the connecting pipe, a breather valve on one side automatically opens, injecting air into the oil reservoir through a conduit, thereby maintaining a stable air pressure inside the oil reservoir. When the piston rod moves forward, it thus... The piston pushes forward inside the suction cylinder, thus pushing the liquid inside the suction cylinder into the oil cylinder through the suction pipe. After the liquid inside the suction cylinder enters the oil cylinder, the liquid on the other side of the oil cylinder enters the oil storage chamber through the diversion groove and the guide groove, and then enters the oil storage cylinder through the connecting pipe connected to the oil storage chamber. This achieves continuous replacement of the liquid inside the oil cylinder. At the same time, coolant is drawn to cool the surface of the suction pipe and the connecting pipe, thereby effectively cooling the liquid flowing through the outside and inside of the suction pipe and the connecting pipe. Therefore, when replacing the liquid inside the oil cylinder, the temperature of the liquid inside the oil cylinder is effectively reduced, thereby maintaining the viscosity coefficient of the liquid inside the oil cylinder and greatly improving the performance of the damping device.

[0020] 2. This invention provides a high-energy-consuming viscous damping device. Through the arrangement of an energy-absorbing plate and a retaining plate, during use, the energy-absorbing spring and energy-absorbing plate, installed on one side inside the cylinder, absorb the seismic energy generated during an earthquake, while simultaneously assisting the piston rod in resetting. When the energy-absorbing plate reciprocates with the piston rod, the retaining plate slides and rubs within its groove. The heat generated by the reciprocating friction of the energy-absorbing plate inside the cylinder is absorbed by the retaining plate. The heat absorbed by the retaining plate diffuses outward from the heat sink on one side, effectively protecting the cylinder body and preventing excessive temperature due to friction. This avoids damage to the cylinder at high temperatures and provides excellent protection for the entire damping device. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Please refer to the following: Figures 1-4 A high-energy-consuming viscous damping device includes an upper plate 1 and a lower plate 3. A damping mechanism 2 is provided between the upper plate 1 and the lower plate 3. A connecting pin 2 is fixedly installed on one side of the hydraulic cylinder 201. A lower node plate 6 is movably installed on the outer side of the connecting pin 2. The lower node plate 6 supports the connecting pin 2, thereby supporting the hydraulic cylinder 201 as a whole. The lower node plate 6 is fixedly installed on the lower plate 3 and fastened with fixing bolts to improve the stability of the lower node plate 6. A connecting pin 1 203 is fixedly installed on one end of the piston rod 202. A movably installed connecting pin 1 203 is mounted on the connecting pin 1 203. The device is equipped with a connecting plate 5, with an upper node plate 16 movably mounted at one end of the connecting plate 5. This assists the damping mechanism 2 in reducing and absorbing the seismic energy generated during an earthquake. The upper node plate 16 is fixedly mounted on the upper plate body 1. When using the damping device, it is first installed by movably connecting the upper node plate 16 to the connecting pin 203 at one end of the piston rod 202. Then, the upper node plate 16 is fixedly mounted below the upper plate body 1 using bolts. Finally, the lower node plate 6 is movably connected to the connecting pin 2 at one end of the hydraulic cylinder 201, thereby completing the damping mechanism 2 as a whole. For easy installation and disassembly of the damping mechanism 2, the lower node plate 6 is bolted to the upper part of the lower plate 3, thus fixing the damping device in place. A mounting cavity is provided on one side of the connecting plate 5, and a connecting rod 9 is fixedly installed inside the cavity. A support spring 8 is movably installed on the outside of the connecting rod 9 to maintain the stability of the lower damping mechanism 2 during shaking. A placement cavity is provided on the connecting pin head 203, and a connecting rod 7 is fixedly installed inside the cavity. The other end of the support spring 8 is movably installed on the outside of the connecting rod 7, facilitating the installation and disassembly of the damping device. When the support spring 8 is installed and used, and the damping mechanism 2 is in use, the connecting plate 5 located below the upper node plate 16 moves. The connecting plate 5 is affected by the shaking force, so the connecting plate 5 swings left and right, thereby offsetting the seismic energy generated during the earthquake. The support spring 8 provides a stretching effect on the lower connecting pin 203, keeping the lower connecting pin 203 in a stable state. When the connecting plate 5 swings left and right, it will pull the lower connecting pin 203 to move simultaneously. The connecting pin 203 will pull the piston rod 202 on one side to move back and forth inside the oil cylinder 201.

[0037] First embodiment:

[0038] Please refer to the following: Figures 5-9In this embodiment, the damping mechanism 2 includes a hydraulic cylinder 201. A fixing plate 212 is fixedly installed inside the hydraulic cylinder 201 to seal the liquid end of the hydraulic cylinder 201, thereby isolating the inside of the hydraulic cylinder 201 and dividing it into two cavities. This allows for more effective absorption and cancellation of shock energy. A second sealing plate 216 is provided on one side of the fixing plate 212 to seal one end of the hydraulic cylinder 201 and prevent liquid from overflowing during use. A first sealing plate 215 is provided on one side inside the hydraulic cylinder 201. The first sealing plate 215 and the second sealing plate 216 are arranged opposite to each other. The first sealing plate 215 is tightly attached to the inner wall of one end of the hydraulic cylinder 201 for fixing. A piston rod 202 is slidably arranged inside the hydraulic cylinder 201. A piston 213 is fixedly mounted on the outer side of the piston rod 202. The piston 213 is adapted to the hydraulic cylinder 201 and is in close contact with the inner wall of the hydraulic cylinder 201. It is used to guide the liquid inside the hydraulic cylinder 201. Several guide holes are opened on the piston 213. When the piston 213 moves inside the hydraulic cylinder 201, the liquid flows continuously through the guide holes, thereby consuming and offsetting the vibration energy. When the piston rod 202 reciprocates inside the hydraulic cylinder 201, it drives the outer piston 213 to reciprocate inside the hydraulic cylinder 201, thereby pushing the liquid inside the hydraulic cylinder 201. The liquid flows through the guide holes opened on the piston 213. During the flow, shear force is generated due to viscosity, which hinders the movement of the piston 213 and converts the vibration kinetic energy into heat energy. The inner wall of the oil cylinder 201 has several oil storage chambers 214 on the side away from the center, which are used to communicate with the external oil storage cylinder 209 and liquid extraction cylinder 206. These oil storage chambers 214 increase liquid storage, thereby enabling continuous liquid exchange. The liquid inside the storage chambers continuously mixes with the liquid inside the oil cylinder 201. A liquid guiding groove 217 is provided on the inner wall of the oil cylinder 201, and the oil storage chambers 214 are connected to the inner side of the oil cylinder 201 through the liquid guiding groove 217 for liquid exchange. A diversion groove 218 is provided at the bottom of the liquid guiding groove 217 on the oil cylinder 201 to guide the liquid inside and outside the oil cylinder 201. The diversion groove 218 is arc-shaped and used for liquid transport. The diversion groove 218 and the liquid guiding groove 217... The cylinder 201 is connected to the oil reservoir 214 via the flow channel 218 and the liquid guide channel 217. An oil reservoir 209 is installed on the outside of the cylinder 201 to store the exchanged liquid and increase the liquid storage capacity. A connecting pipe 208 is fixedly installed at one end of the oil reservoir 209, communicating with the oil reservoir 214 to facilitate liquid transport within the oil reservoir 209. A conduit 210 is fixedly installed on the oil reservoir 209 opposite to the connecting pipe 208, and a breather valve 211 is fixedly installed on the outside of the conduit 210. The breather valve 211 automatically controls the air pressure inside the oil reservoir 209. An adjusting component is provided on one side of the oil reservoir 209 on the cylinder 201 to adjust the liquid level inside the cylinder 201.The adjusting component includes a liquid extraction cylinder 206, with a liquid extraction pipe 207 fixedly installed at one end of the liquid extraction cylinder 206. The liquid extraction pipe 207 is located on one side of the connecting pipe 208, and the liquid extraction pipe 207 and the connecting pipe 208 are located on the same side of the hydraulic cylinder 201. The liquid extraction pipe 207 communicates with the connecting pipe 208 through the hydraulic cylinder 201, thereby realizing the intake and extraction of liquid. Mounting blocks 205 are fixedly installed on both the liquid extraction cylinder 206 and the oil storage cylinder 209. The mounting blocks 205 are in contact with the surface of the hydraulic cylinder 201 to assist in the extraction. The liquid pipe 207 is installed in the oil storage chamber 214. The liquid extraction cylinder 206 and the oil storage cylinder 209 are fixedly installed on the oil cylinder 201 by the mounting block 205, which improves the stability of the liquid extraction pipe 207 and the oil storage chamber 214, thereby preventing the liquid extraction cylinder 206 and the oil storage cylinder 209 from shaking or falling off during use, which would affect the delivery of liquid. A piston 219 is provided inside the liquid extraction cylinder 206. The piston 219 is used to extract liquid. A stabilizing rod 204 is fixedly installed on one side of the piston 219. The piston 219 is used to reciprocate. The other end of the stabilizing rod 204 is fixedly mounted on the piston rod 202. The movement of the piston rod 202 causes the stabilizing rod 204 to move synchronously. During the reciprocating movement of the piston rod 202 for shock absorption, the liquid is simultaneously extracted and replaced, thereby reducing the temperature of the liquid inside the cylinder 201 and preventing a decrease in the liquid's viscosity coefficient. The piston 219 is slidably mounted inside the suction cylinder 206. The piston 219 and the suction cylinder 206 are... The fitting improves the sealing between piston 219 and the suction pipe 207. Therefore, through the arrangement of piston 219 and stabilizing rod 204, when stabilizing rod 204 moves, it drives piston 219 to move within suction cylinder 206. When piston 219 moves backward, it draws liquid from inside oil cylinder 201 through suction pipe 207, causing the liquid to be drawn into suction cylinder 206. Meanwhile, the liquid inside oil reservoir 209 on the other side is connected... Pipe 208 injects liquid into the oil cylinder 201, thereby exchanging the liquid inside the oil cylinder 201 and effectively reducing the temperature of the liquid inside the oil cylinder 201. When liquid is injected into the oil reservoir 209 through connecting pipe 208, the breather valve 211 on one side automatically opens, and air is injected into the oil reservoir 209 through conduit 210, thereby keeping the air pressure inside the oil reservoir 209 stable. When piston rod 202 moves forward, it causes piston 219 at one end to pump... The liquid cylinder 206 is pushed forward, thus pushing the liquid inside the suction cylinder 206 into the oil cylinder 201 through the suction pipe 207. After the liquid in the suction cylinder 206 enters the oil cylinder 201, the liquid on the other side of the oil cylinder 201 enters the oil storage chamber 214 through the diversion groove 218 and the guide groove 217, and then enters the oil storage cylinder 209 through the connecting pipe 208 connected to the oil storage chamber 214, thereby continuously replacing the liquid inside the oil cylinder 201.

[0039] Please refer to the following: Figure 10 A cooling component 4 is installed below the hydraulic cylinder 201. The cooling component 4 includes several protective cylinders 406, which are respectively sleeved on the outside of the liquid extraction pipe 207 and the connecting pipe 208. The diameter of the protective cylinder 406 is larger than the diameter of the liquid extraction pipe 207 and the connecting pipe 208. A liquid-gathering cavity is formed between the inner wall of the protective cylinder 406 and the outer wall of the liquid extraction pipe 207 and the connecting pipe 208. Coolant is drawn into the liquid-gathering cavity to cool the liquid extraction pipe 207 and the connecting pipe 208. An outlet hole is opened at the bottom of the protective cylinder 406. When the liquid-gathering cavity is full of coolant, the coolant inside the liquid-gathering cavity is circulated by the continuous injection of coolant. The fluid is discharged through the outlet. An infusion pipe 407 is fixedly installed on the protective cylinder 406, connecting several protective cylinders 406. An outlet pipe 405 is fixedly installed on one side of the infusion pipe 407, and a one-way valve 408 is installed on the outlet pipe 405. A guide cylinder 401 is fixedly installed at one end of the outlet pipe 405, and the guide cylinder 401 is fixedly installed below the oil cylinder 201. A suction plug is movably installed inside the guide cylinder 401, and a suction rod 404 is fixedly installed on one side of the suction plug. The end of the suction rod 404 is fixedly installed on the piston rod 202. An inlet pipe 403 is fixedly installed below one side of the guide cylinder 401, and a one-way valve 403 is installed on the inlet pipe 403. 409. A liquid storage tank 402 is installed at the bottom of the inlet pipe 403. The liquid storage tank 402 is fixedly installed on the lower plate 3 and located at the bottom of the oil cylinder 201. The upper part of the liquid storage tank 402 is open, which is used for the recovery of the extracted coolant. Specifically, when the piston rod 202 moves, it will simultaneously drive the lower suction rod 404 to move backward. When the suction rod 404 moves, it will drive the suction plug at one end to move. When the suction rod 404 moves, the one-way valve 2 409 opens, and the coolant inside the liquid storage tank 402 is drawn through the inlet pipe 403. The coolant enters the liquid guide cylinder 401 through the inlet pipe 403. When the suction rod 404 moves, the one-way valve 2 409 opens, and the coolant inside the liquid storage tank 402 is drawn through the inlet pipe 403. During reset, the liquid-drawing plug is pushed forward, and at the same time, the one-way valve 408 opens. The coolant inside the liquid guide cylinder 401 enters the liquid delivery pipe 407 through the liquid outlet pipe 405. Then, the coolant is injected into the protective cylinder 406 through the liquid delivery pipe 407, thereby cooling the liquid-drawing pipe 207 and the connecting pipe 208 inside the protective cylinder 406. Thus, the liquid flowing through the liquid-drawing pipe 207 and the connecting pipe 208 is cooled. The coolant injected into the protective cylinder 406 flows out through the outlet at the bottom to provide auxiliary cooling to the surface of the cylinder 201. The coolant flowing into the surface of the cylinder 201 flows downward again into the storage tank 402.

[0040] The working principle of the high-energy-consuming viscous damping device provided by this invention is as follows:

[0041] Step 1: When using the damping device, first install the damping device by movably connecting the upper node plate 16 to the connecting pin 203 at one end of the piston rod 202, then fixing the upper node plate 16 to the lower part of the upper plate body 1 with bolts, then movably connecting the lower node plate 6 to the connecting pin 2 at one end of the oil cylinder 201, and then fixing the lower node plate 6 to the upper part of the lower plate body 3 with bolts, thereby installing and fixing the damping device.

[0042] Step 2: When the damping device is in use, the connecting plate 5 located below the upper node plate 16 moves. The connecting plate 5 is affected by the shaking force, so the connecting plate 5 swings left and right, thereby offsetting the seismic energy generated during the earthquake.

[0043] The support spring 8 provides tension to the lower connecting pin 203, keeping it stable. When the connecting plate 5 swings left and right, it pulls the lower connecting pin 203 to move simultaneously. The connecting pin 203 then pulls the piston rod 202 on one side to move back and forth inside the oil cylinder 201.

[0044] When the piston rod 202 reciprocates inside the oil cylinder 201, it drives the outer piston 213 to reciprocate inside the oil cylinder 201, thereby pushing the liquid inside the oil cylinder 201. The liquid flows through the guide hole opened on the piston 213. During the flow, shear force is generated due to viscosity, which hinders the movement of the piston 213 and converts the vibration kinetic energy into heat energy for dissipation.

[0045] Step 3: When the piston rod 202 reciprocates, it will simultaneously drive the two outer stabilizing rods 204 to move. When the stabilizing rods 204 move, they will drive the piston 219 at one end to move in the liquid extraction cylinder 206. When the piston 219 moves backward, it will draw liquid from the inside of the oil cylinder 201 through the liquid extraction pipe 207, so that the liquid is drawn into the liquid extraction cylinder 206. Meanwhile, the liquid inside the oil storage cylinder 209 on the other side is injected into the oil cylinder 201 through the connecting pipe 208, thereby exchanging the liquid inside the oil cylinder 201 and effectively reducing the temperature of the liquid inside the oil cylinder 201.

[0046] Furthermore, when the piston rod 202 moves, it simultaneously drives the lower suction rod 404 to move backward. When the suction rod 404 moves, it drives the suction plug at one end to move. When the suction rod 404 moves, the second check valve 409 opens, drawing coolant from inside the storage tank 402 through the inlet pipe 403. The coolant enters the guide cylinder 401 through the inlet pipe 403. When the suction rod 404 returns to its original position, it pushes the suction plug forward, and at the same time, the first check valve 408 opens, allowing coolant inside the guide cylinder 401 to flow outward. The liquid pipe 405 enters the inside of the liquid delivery pipe 407, and then the coolant is injected into the inside of the protective cylinder 406 through the liquid delivery pipe 407, thereby cooling the liquid extraction pipe 207 and the connecting pipe 208 inside the protective cylinder 406. Thus, the liquid flowing through the liquid extraction pipe 207 and the connecting pipe 208 is cooled. The coolant injected into the protective cylinder 406 flows out through the outlet at the bottom to provide auxiliary cooling for the surface of the oil cylinder 201, and the coolant flowing into the surface of the oil cylinder 201 flows downward again into the storage tank 402.

[0047] When liquid is injected into the oil reservoir 209 through the connecting pipe 208, the breather valve 211 on one side automatically opens, and air is injected into the oil reservoir 209 through the conduit 210, thereby keeping the air pressure inside the oil reservoir 209 stable.

[0048] When the piston rod 202 moves forward, it pushes the piston 219 at one end forward inside the liquid extraction cylinder 206. This pushes the liquid inside the liquid extraction cylinder 206 into the oil cylinder 201 through the liquid extraction pipe 207. After the liquid inside the liquid extraction cylinder 206 enters the oil cylinder 201, the liquid on the other side of the oil cylinder 201 enters the oil storage chamber 214 through the drainage groove 218 and the liquid guide groove 217, and then enters the oil storage cylinder 209 through the connecting pipe 208 connected to the oil storage chamber 214, thereby realizing the continuous replacement of the liquid inside the oil cylinder 201.

[0049] Compared with related technologies, the high-energy-consuming viscous damping device provided by the present invention has the following beneficial effects:

[0050] This invention provides a high-energy-consuming viscous damping device. Through the adjustment mechanism, when shaking occurs, the piston rod 202 reciprocates, simultaneously driving the two outer stabilizing rods 204 to move. When the stabilizing rods 204 move, they drive one end of the piston 219 to move within the suction cylinder 206. When the piston 219 moves backward, it draws liquid from inside the oil cylinder 201 through the suction pipe 207, transferring the liquid into the suction cylinder 206. Meanwhile, liquid inside the oil storage cylinder 209 on the other side is injected into the oil cylinder 201 through the connecting pipe 208. When liquid is injected into the oil storage cylinder 209 through the connecting pipe 208, the breather valve 211 on one side automatically opens, injecting air into the oil storage cylinder 209 through the conduit 210, thereby increasing the energy efficiency of the storage cylinder. The internal air pressure of the oil cylinder 209 remains stable. When the piston rod 202 moves forward, it pushes the piston 219 at one end forward inside the liquid extraction cylinder 206. This pushes the liquid inside the liquid extraction cylinder 206 into the oil cylinder 201 through the liquid extraction pipe 207. After the liquid inside the liquid extraction cylinder 206 enters the oil cylinder 201, the liquid on the other side of the oil cylinder 201 enters the oil storage chamber 214 through the drainage groove 218 and the liquid guide groove 217, and then enters the oil storage cylinder 209 through the connecting pipe 208 connected to the oil storage chamber 214. This achieves continuous replacement of the liquid inside the oil cylinder 201, effectively reducing the temperature of the liquid inside the oil cylinder 201 and maintaining the viscosity coefficient of the liquid inside the oil cylinder 201. Therefore, it greatly improves the performance of the damping device.

[0051] Second embodiment:

[0052] Please refer to the following: Figures 11-13In this embodiment, an energy-absorbing spring 13 is fixedly installed at one end of the hydraulic cylinder 201, and an energy-absorbing plate 11 is fixedly installed at the other end of the energy-absorbing spring 13. The diameter of the energy-absorbing plate 11 is smaller than the inner diameter of the hydraulic cylinder 201. There are multiple energy-absorbing springs 13, which are evenly arranged on one side of the energy-absorbing plate 11 to evenly stretch the energy-absorbing plate 11, thereby improving the stability of the energy-absorbing plate 11 during use. The energy-absorbing plate 11 is located on one side of the fixed plate 212. The hydraulic cylinder 201 is separated by the fixed plate 212 for the installation and placement of the energy-absorbing plate 11. Therefore, the energy-absorbing plate 11 is located on one side inside the other hydraulic cylinder 201. When the piston rod 202 is stretched, the energy-absorbing plate 11 at one end is stretched simultaneously. The energy-absorbing plate 11 is disc-shaped. When the energy-absorbing plate 11 is pulled, the energy-absorbing plate 11 will... The inner extending plate 15 is rubbed to conduct heat. Both the energy-absorbing plate 11 and the fixing plate 212 have through holes in their middle sections. One end of the piston rod 202 is movably disposed inside the through hole, with its outer wall fitting against the inner wall of the through hole. Therefore, when the piston rod 202 moves, the energy-absorbing plate 11 moves simultaneously with it. Since the energy-absorbing plate 11 is movably sleeved on the piston rod 202, during an earthquake, the shaking of the energy-absorbing plate 11 gradually offsets the vibration energy, gradually absorbing the generated vibration energy. The energy-absorbing plate 11 is movably installed on the outside of the piston rod 202, and multiple sets of limiting pins 14 are fixedly installed on the outside of the piston rod 202. The limiting pins 14 stabilize both sides of the energy-absorbing plate 11, thus limiting the energy absorption and preventing energy absorption. In the event of plate 11 detaching from piston rod 202, limiting pins 14 are located on both sides of the energy-absorbing plate 11 to fix its position and improve its stability during use. The limiting pins 14 have threads on their lower outer sides, and a threaded hole is located on one end of piston rod 202. The limiting pins 14 are locked onto piston rod 202 through the threaded hole. Therefore, tightening the limiting pins 14 facilitates their installation and removal, thereby facilitating the overall installation and removal of the energy-absorbing plate 11. A retaining plate 15 is fixedly installed on one side inside the hydraulic cylinder 201. The retaining plate 15 limits the position of the energy-absorbing plate 11 and absorbs the high temperature generated by friction between the energy-absorbing plate 11 and the retaining plate 15, then discharges the generated high temperature, thus maintaining the stability of the energy-absorbing plate 11. The mechanical properties provide good protection for the energy-absorbing plate 11 as a whole and reduce the contact between the energy-absorbing plate 11 and the hydraulic cylinder 201, thus providing good protection for the hydraulic cylinder 201. A heat sink 10 is fixedly installed on the top of the clamping plate 15 to dissipate the high temperature absorbed by the clamping plate 15. The heat sink 10 is in contact with the clamping plate 15, which allows the high temperature to be discharged into the air, preventing the high temperature from staying inside the hydraulic cylinder 201 and causing the hydraulic cylinder 201 to creep and reduce its strength at high temperatures. The heat sink 10 is located on the outside of the hydraulic cylinder 201. A slot 12 is opened on the energy-absorbing plate 11, and the clamping plate 15 is located inside the slot 12 to limit the position of the energy-absorbing plate 11 and protect it. The outer side of the clamping plate 15 is in contact with the inner wall of the slot 12.The clamping plate 15 and the clamping slot 12 are compatible, thus providing good heat conduction for the clamping plate 15. The clamping plate 15 is inserted deep inside the energy-absorbing plate 11, thereby absorbing the generated high temperature. When the piston rod 202 reciprocates, it simultaneously drives the energy-absorbing plate 11 at one end to move. When the energy-absorbing plate 11 moves, it stretches the energy-absorbing spring 13 on one side, thus continuously absorbing the seismic energy generated during the earthquake. Meanwhile, another set of energy-absorbing plates 11 and energy-absorbing spring 13 on one side simultaneously absorb the seismic energy. When the energy-absorbing plate 11 reciprocates, it slides and rubs inside the clamping slot 12 through the clamping plate 15. Therefore, the heat generated by the reciprocating friction of the energy-absorbing plate 11 inside the cylinder 201 is absorbed by the clamping plate 15. The heat absorbed by the clamping plate 15 diffuses outward from the heat sink 10 on one side, thereby effectively protecting the cylinder 201 body.

[0053] With the energy-absorbing plate 11 and the clamping plate 15 installed inside the cylinder 201, the energy-absorbing spring 13 and the energy-absorbing plate 11 are used to absorb the seismic energy generated during an earthquake. At the same time, they assist the piston rod 202 in the middle to reset. When the energy-absorbing plate 11 moves back and forth with the piston rod 202, the clamping plate 15 slides and rubs inside the groove 12. The heat generated by the friction of the energy-absorbing plate 11 moving back and forth inside the cylinder 201 is absorbed by the clamping plate 15. The heat absorbed by the clamping plate 15 diffuses outward from the heat sink 10 on one side, thereby effectively protecting the cylinder 201 body and preventing the cylinder 201 body from overheating due to friction. This avoids damage to the cylinder 201 at high temperatures and provides good protection for the entire damping device.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
