Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a turbine-type viscous damper. Background Technology

[0002] A turbine-type viscous damper is an engineering energy-dissipating vibration reduction device that generates damping force by utilizing the interaction between viscous fluid and its structural components in order to dissipate vibration energy.

[0003] Turbine-type viscous dampers have a wide range of applications, mainly including high-rise buildings, bridges, seismic retrofitting of building structures, seismic resistance of industrial pipelines and equipment, and military applications. Due to their ease of installation, wide applicability, and cost-effectiveness, and because they do not alter the natural frequency characteristics of the structure or provide additional structural stiffness, they are an ideal passive energy-dissipating and vibration-damping device.

[0004] Conventional turbine-type viscous dampers have a relatively limited operating stroke, which results in a relatively limited damping force and a limited kinetic energy that can be withstood in a short period of time. When encountering kinetic energy exceeding the threshold, they are prone to damage to their own structure, thereby affecting the normal operation of the device in the future.

[0005] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a turbine-type viscous damper. Utility Model Content

[0006] The purpose of this invention is to provide a turbine-type viscous damper to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a turbine-type viscous damper, comprising a hydraulic cylinder structure and a turbine-type piston structure. A piston rod is horizontally mounted inside the hydraulic cylinder structure. The turbine-type piston structure is mounted on one end of the piston rod and has two sets of components. A pin head structure is mounted on both the end of the piston rod away from the turbine-type piston structure and the end of the hydraulic cylinder structure away from the piston rod. A pin seat structure is connected to one end of each pin head structure. The turbine-type piston structure includes a high-damping bearing, turbine blades, a support ring, and a sealing ring. The surface of the high-damping bearing is connected to the turbine blades, and the end of the turbine blades away from the high-damping bearing is connected to the support ring. A sealing ring is mounted on the edge surface of the support ring.

[0008] Furthermore, the cylinder structure includes a cylinder body, an end cover, and a pressure accumulator structure. The end cover is installed at the end of the cylinder body near the piston rod, and the pressure accumulator structure is installed at the end of the cylinder body away from the end cover.

[0009] Furthermore, the cylinder structure also includes a control valve and a support structure. The control valve is installed at one end of the accumulator structure near the piston rod, and the support structure is installed in the middle of the inner side of the cylinder body.

[0010] Furthermore, the interior of the cylinder is divided into a cavity structure by the end cap and the support structure, and a damping medium is injected inside the cavity structure. The support structure and the control valve are also divided into a cavity structure inside the cylinder and a damping medium is injected inside the cavity structure.

[0011] Furthermore, the accumulator structure and control valve are separated into a cavity structure inside the cylinder body, and the control valve and support structure are both fixedly installed inside the cylinder body. Moreover, the end of the piston rod away from the pin structure passes horizontally through the center of the support structure.

[0012] Furthermore, the high-damping bearing is nested on the end surface of the piston rod away from the pin head structure, and the turbine blades are welded to the support ring and the high-damping bearing respectively, and the sealing ring is nested on the surface of the support ring.

[0013] Furthermore, the pin seat structure includes a connecting pin seat, a stabilizing pin, and a limiting post. The stabilizing pin is horizontally installed on the top of one end of the connecting pin seat near the cylinder structure, and the limiting post is vertically connected to the bottom surface of the connecting pin seat.

[0014] Furthermore, the limiting post and the connecting pin are threaded together and can be disassembled and reassembled, and both ends of the connecting pin are vertically provided with mounting holes.

[0015] This invention provides a turbine-type viscous damper, which has the following advantages:

[0016] 1. This utility model, by installing two sets of turbine piston structures at the end of the piston rod away from the pin structure, wherein a set of turbine blades is symmetrically installed on the two end surfaces of the high-damping bearing, allows the entire turbine piston structure to provide sufficient structural friction when the piston rod reciprocates horizontally inside the cylinder structure, utilizing the characteristics of its structure to rotate within the damping medium. At the same time, the axial rotational friction provided by the high-damping bearing itself, and the friction generated by the sealing ring nested on the surface of the support ring rotating along the inner wall surface of the cylinder, allow the damping medium to generate sufficient throttling damping at the gaps between the tightly annularly distributed turbine blades, thereby ensuring that the device can dissipate the seismic energy of the building to the greatest extent possible, and thus ensuring the practicality of the device structure.

[0017] 2. This utility model features a pressure accumulator structure and a control valve installed at one end of the cylinder body. The pressure accumulator structure and control valve create a cavity within the cylinder body, which remains hollow under normal conditions. When the damping medium within this cavity accumulates sufficient kinetic energy and cannot effectively dissipate it, the control valve diverts the damping medium from the pressure accumulator structure and control valve into the cavity. This structure effectively mitigates the impact of excessive kinetic energy transmission and absorption, providing excellent self-protection and preventing unnecessary structural damage from excessive kinetic energy. This ensures the overall service life of the device. Furthermore, the pressure accumulator structure and support structure provide excellent structural support within the cylinder body, guaranteeing its overall structural strength.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 4As shown, a turbine-type viscous damper includes a cylinder structure 1 and a turbine-type piston structure 3. A piston rod 2 is horizontally mounted inside the cylinder structure 1. The turbine-type piston structure 3 is mounted on one end of the piston rod 2 and has two sets of components. A pin head structure 4 is mounted on both the end of the piston rod 2 away from the turbine-type piston structure 3 and the end of the cylinder structure 1 away from the piston rod 2. A pin seat structure 5 is connected to one end of the pin head structure 4. The turbine-type piston structure 3 includes a high-damping bearing 301, turbine blades 302, a support ring 303, and a sealing ring 304. The turbine blades 302 are connected to the surface of the high-damping bearing 301, and the turbine blades 302 are located away from the high-damping bearing 301. The piston rod 2 is connected to a support ring 303, and a sealing ring 304 is installed on the edge surface of the support ring 303. The high-damping bearing 301 is nested on the end surface of the piston rod 2 away from the pin structure 4. The turbine blades 302 are welded to the support ring 303 and the high-damping bearing 301 respectively. The sealing ring 304 is nested on the surface of the support ring 303. A set of turbine blades 302 is symmetrically installed on each of the two ends of the high-damping bearing 301. This allows the entire turbine piston structure 3 to provide sufficient structural friction when the piston rod 2 reciprocates horizontally inside the cylinder structure 1 and rotates inside the damping medium by utilizing the characteristics of its structure.

[0025] like Figures 1 to 4As shown, the hydraulic cylinder structure 1 includes a cylinder body 101, an end cap 102, and a pressure accumulator structure 103. The end cap 102 is installed at the end of the cylinder body 101 near the piston rod 2, and the pressure accumulator structure 103 is installed at the end of the cylinder body 101 away from the end cap 102. The hydraulic cylinder structure 1 also includes a control valve 104 and a support structure 105. The control valve 104 is installed at the end of the pressure accumulator structure 103 near the piston rod 2, and the support structure 105 is installed in the middle of the inner side of the cylinder body 101. The interior of the cylinder body 101 utilizes… A cavity structure is divided by end cap 102 and support structure 105 and filled with damping medium. A cavity structure is also divided within cylinder body 101 by support structure 105 and control valve 104 and filled with damping medium. A cavity structure is also divided within cylinder body 101 by accumulator structure 103 and control valve 104. Both control valve 104 and support structure 105 are fixedly installed inside cylinder body 101. Furthermore, the end of piston rod 2 furthest from pin head structure 4 passes horizontally through... At the center of the support structure 105, the pin seat structure 5 includes a connecting pin seat 501, a stabilizing pin 502, and a limiting post 503. The stabilizing pin 502 is horizontally installed on the top of the end of the connecting pin seat 501 near the cylinder structure 1, and the limiting post 503 is vertically connected to the bottom surface of the connecting pin seat 501. The limiting post 503 and the connecting pin seat 501 are threaded together and can be disassembled. Both ends of the connecting pin seat 501 are vertically provided with mounting holes. The accumulator structure 103 and the control valve 104 will separate a cavity structure inside the cylinder body 101. The cavity remains hollow under normal conditions. Once the damping medium inside the cavity structure between the accumulator structure 103 and the control valve 104 has borne a sufficient amount of kinetic energy and is difficult to dissipate effectively, the operation of the control valve 104 can be used to divert the damping medium between the accumulator structure 103 and the control valve 104 into the cavity structure separated between the accumulator structure 103 and the control valve 104.

[0026] In summary, as Figures 1 to 4 As shown, when using this turbine-type viscous damper, firstly, according to the installation position of the device, holes corresponding to the distribution structure of the limit stakes 503 can be pre-drilled at the installation position. Then, the limit stakes 503 on the bottom surface of the connecting pin seat 501 are inserted into the holes drilled on the installation structure surface. At the same time, with the use of bolts, the entire pin seat structure 5 is fixed to the installation structure surface by utilizing the installation hole structure with vertical holes at both ends of the connecting pin seat 501. This ensures the maximum firmness and stability of the entire device after installation. During this period, the pin head structure 4 at one end of the cylinder structure 1 and the piston rod 2, together with the stabilizing pin shaft 502, can rotate the pin seat structure 5 to adjust to a suitable angle to ensure that the bottom of the connecting pin seat 501 can fit the installation structure surface to the maximum extent.

[0027] When the entire device experiences vibration kinetic energy due to external factors, the piston rod 2 will reciprocate inside the cylinder structure 1 due to the vibration kinetic energy. During this process, the two sets of turbine piston structures 3 connected to one end of the piston rod 2 will move synchronously. The damping medium between the end cover 102 and the support structure 105 will be compressed by the structure and enter from one side of the turbine blade 302 through the gap in its structure. Due to the characteristics of the turbine blade 302's own structure, the damping medium and the surface of the turbine blade 302 have sufficient contact surface, thereby generating sufficient throttling damping. Due to the characteristics of the turbine blade 302's own structure, the damping medium will drive the turbine blade 302 to rotate axially around the piston rod 2 as the axis while passing through the turbine blade 302. At this time, the high-damping bearing 301 will provide a certain degree of structural friction force without affecting the structural rotation of the turbine blade 302. At the same time, the support ring 303 connected to the turbine blade 302 and with a sealing ring 304 nested on its surface. It will rotate synchronously with the rotation of the turbine blade 302, and drive the sealing ring 304 to rotate axially on the inner wall surface of the cylinder 101, thereby generating sufficient rotational friction between the cylinder 101 and the sealing ring 304. The above-mentioned structures cooperate with each other to form a sufficient amount of damping force, so that the seismic energy can be converted into heat dissipation through the reciprocating motion of the turbine piston structure 3 in the damping medium, so that the speed of the turbine piston structure 3 gradually decreases, achieving the purpose of damping and energy dissipation.

[0028] During this process, the piston rod 2 passes through one end of the support structure 105 and moves back and forth inside the cavity formed between the support structure 105 and the control valve 104. At the same time, there is also a certain amount of damping medium inside this cavity, which generates a certain degree of damping force in conjunction with the movement of the piston rod 2. If the vibration kinetic energy between the support structure 105 and the control valve 104 reaches a certain level, the control valve 104 can be used to divert the damping medium between the two to the cavity structure separated by the control valve 104 and the pressure accumulator structure 103, thereby playing a role in pressure relief protection and ensuring the operational stability of the entire device.
