TECHNICAL FIELD

[0001] The utility model relates to viscous damper technical field, concretely is a kind of high energy dissipation viscous damper with multistage energy dissipation cavity structure. BACKGROUND

[0002] High-efficiency viscous damper is a speed-dependent damper, mainly through fluid motion to generate damping force, especially suitable for relieving the impact and damage of earthquake on building structure. Its internal structure usually adopts jet type design, such as single rod type damper, through the reciprocating movement of piston to make liquid flow through the small hole on the piston head, thereby providing damping force.

[0003] The existing patent CN205064676U discloses a high energy dissipation viscous damper, although the patent can solve the problem that the damping hole is directly opened on the piston in the traditional damper, so that different pistons need to be replaced for different tonnage dampers, which will cause waste of resources. However, after long time operation of the patent, its own heat will gradually increase, and if the heat increases, the viscosity of the viscous fluid will decrease, which will reduce the damping force of the damper, thereby affecting its energy dissipation effect and control ability of structural vibration, and it cannot stably provide additional damping required by design for the structure. Therefore, a high energy dissipation viscous damper with multistage energy dissipation cavity structure is invented. SUMMARY

[0013] A spring is sleeved on the T-shaped rod, and two ends of the spring are fixedly connected with the head of the T-shaped rod and the side surface of the connecting block.

[0014] As a preferred scheme of the high-energy consumption viscous damper with the multi-stage energy consumption cavity structure, both ends of the piston rod are fixedly installed with the pistons through the clamping pieces, and the piston rod is sleeved with a reset spring, and two ends of the reset spring are fixedly connected with the pistons and the partition plate.

[0015] As a preferred scheme of the high-energy consumption viscous damper with the multi-stage energy consumption cavity structure, a plurality of damping holes are arranged on the piston, and diameters of the plurality of damping holes are different.

[0016] As a preferred scheme of the high-energy consumption viscous damper with the multi-stage energy consumption cavity structure, a dustproof shield is slidably sleeved on the left end of the cylinder body, and the piston rod penetrates through the dustproof shield.

[0018] As a preferred scheme of the high-energy consumption viscous damper with the multi-stage energy consumption cavity structure, a plugging block is inserted into the damping hole, and the plugging block is fixedly installed on one side of the annular plate.

[0019] Compared with the prior art, the high-energy consumption viscous damper with the multi-stage energy consumption cavity structure has the following advantages:

[0020] 1. The cylinder body is divided into two cavities by the partition plate and the cylinder body, and two groups of pistons independently move in the two cavities, so that the energy consumption capacity of the viscous damper is improved, the energy consumption capacity is doubled compared with the traditional viscous damper, and the high-energy consumption effect can be achieved based on the multi-stage energy consumption cavity structure.

[0021] 2. By setting up the sleeve and heat-conducting plate, the high-efficiency viscous damper can be cooled. By cooling the high-efficiency viscous damper, the viscosity of the viscous fluid can be reduced due to temperature to a certain extent. In addition, by setting up the connecting component, the heat-conducting plate can be easily disassembled and installed by personnel, which is convenient for later maintenance and other operations.

[0022] 3. By opening several damping holes of different diameters on the piston and sealing them with a sealing plate, it is possible to simply remove the corresponding sealing plate when a damper of different tonnage is required, which improves convenience. Attached Figure Description
