DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 A viscous fluid energy dissipator in this embodiment includes an oil pipe 1, a connecting rod 2 is fixed to the inner side of the oil pipe 1, a cover plate 3 is fixed to the left side of the oil pipe 1, and a reset mechanism 4 for rapid recovery is arranged on the cover plate 3, so that the energy dissipator can be quickly reset after completing the work, reducing the pressure on the building, a blocking block 5 is fixed to the right side of the cover plate 3, and a sealing ring 6 is fixed to the outer side of the blocking block 5, so as to improve the sealing inside the oil pipe 1 and avoid leakage of the energy dissipation medium, and a filling mechanism 7 for filling and releasing the energy dissipation medium is arranged on the oil pipe 1, so that the energy dissipation medium can be filled or discharged without disassembling the energy dissipator.

[0022] The inner diameter of the oil pipe 1 is equal to the outer diameter of the connecting rod 2 , and the inner diameter of the oil pipe 1 is matched with the outer diameter of the sealing ring 6 to ensure that the inside of the oil pipe 1 is completely sealed, and a cavity is opened inside the connecting rod 2 .

[0023] See also Figure 2 In order to enable the energy dissipator to quickly reset after completing its work and reduce the pressure on the building, the reset mechanism 4 in this embodiment includes a spring 401, one end of the spring 401 is fixed to the left side of the cover plate 3, and the other end of the spring 401 is fixed with a connecting plate 402. When the energy dissipator is working, the cover plate 3 on the oil pipe 1 will squeeze the spring 401 between the connecting plate 402. After being squeezed, the spring 401 generates elastic potential energy, which will exert elastic force on the connecting plate 402, so that the connecting plate 402 quickly returns to its initial position, thereby facilitating the rapid reset of the energy dissipator. The right side of the connecting plate 402 is fixed with a A connecting block 403, a first mounting hole 404 is provided on the front side of the first connecting block 403, a first bearing 405 is fixed on the inner side of the first mounting hole 404, a second connecting block 406 is fixed on the right side of the connecting rod 2, a second mounting hole 407 is provided on the front side of the second connecting block 406, a second bearing 408 is fixed on the inner side of the second mounting hole 407, the first bearing 405 on the first connecting block 403 and the second bearing 408 on the second connecting block 406 are respectively fixed to the pin seats on both sides of the building, so that the energy dissipator is connected between the two sides of the building, and a damping component is arranged on the connecting plate 402.

[0024] In this example, the first connection block 403 and the second connection block 406 are located on the same horizontal line, and the inner diameter of the first mounting hole 404 matches the inner diameter of the second mounting hole 407, so that the forces acting on both ends of the energy dissipator can act on the same line.

[0025] It should be noted that the damping assembly includes a piston rod 409, one end of which is fixed to the right side of the connecting plate 402, and the other end of the piston rod 409 passes through the left side of the cover plate 3 and extends into the cavity of the connecting rod 2, the cavity can provide a space for the piston rod 409 to move, and a damping piston 410 is fixed to the outside of the piston rod 409. When vibration occurs, the two sides of the building will be displaced, thereby driving the pin seat to move, and the pin seat drives the first connecting block 403 or the second connecting block 406 to move, so that the oil pipe 1 and the damping piston 410 are in contact with each other. 0, the damping piston 410 squeezes the energy dissipation medium inside the oil pipe 1, so that the kinetic energy generated by the building vibration is converted into heat energy, thereby reducing the deformation caused by the building vibration, so that the building is protected. A groove 411 is provided on the outer side of the damping piston 410, and the groove 411 can improve the performance and durability of the energy dissipator. The outer diameter of the damping piston 410 is adapted to the inner diameter of the oil pipe 1, and the inner diameter of the groove 411 is smaller than the outer diameter of the damping piston 410, so that the damping piston 410 can slide inside the oil pipe 1.

[0026] See also Figure 3In order to improve the sealing performance inside the oil pipe 1 and avoid leakage of the energy dissipation medium, the filling mechanism 7 in this embodiment includes a feed pipe 701. A connecting hole 702 is opened on the outside of the oil pipe 1. A feed pipe 701 is fixed on the inside of the connecting hole 702. The outside of the feed pipe 701 is connected with a feed valve 703. The feed valve 703 is opened to open the feed pipe 701. When the feed pipe 701 is opened, the energy dissipation medium can be injected or discharged without disassembling the energy dissipator, thereby improving the operating efficiency of the energy dissipator and enhancing the performance of the energy dissipator. An isolation net 704 is fixed on the inside of the feed pipe 701. The isolation net 704 can filter impurities in the energy dissipation medium when the energy dissipation medium inside the oil pipe 1 is injected.

[0027] In this example, the isolation net 704 is located above the feed valve 703, so that the impurities can be quickly cleaned off the isolation net 704 after being filtered out. The outer diameter of the isolation net 704 is compatible with the inner diameter of the feed pipe 701.

[0028] The working principle of the above embodiment is:

[0029] (1) The first bearing 405 on the first connecting block 403 and the second bearing 408 on the second connecting block 406 are respectively fixed to the pin seats on both sides of the building, so that the energy dissipator is connected between the two sides of the building. When the building vibrates, the two sides of the building will be displaced, thereby driving the pin seats to move. The pin seats drive the first connecting block 403 or the second connecting block 406 to move, so that the oil pipe 1 and the damping piston 410 move relative to each other. The damping piston 410 squeezes the energy dissipation medium inside the oil pipe 1, so that the kinetic energy generated by the building vibration is converted into heat energy, thereby reducing the deformation caused by the building vibration, so that the building is protected.

[0030] (2) When the oil pipe 1 and the damping piston 410 are in relative motion, the cover plate 3 on the oil pipe 1 will squeeze the spring 401 between the connecting plate 402. After being squeezed, the spring 401 generates elastic potential energy and exerts elastic force on the connecting plate 402, so that the connecting plate 402 quickly returns to its initial position, thereby facilitating the rapid resetting of the energy dissipator. After the energy dissipator is installed, the energy dissipation medium needs to be filled into the oil pipe 1. At the same time, the energy dissipation medium needs to be replaced after the energy dissipator has been used for a certain period of time. The feed valve 703 is opened to open the feed pipe 701. When the feed pipe 701 is opened, the energy dissipation medium can be injected or discharged without disassembling the energy dissipator, thereby improving the operating efficiency of the energy dissipator and enhancing the performance of the energy dissipator.
