Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and particularly relates to a liquid-cooled temperature-controlled gapless viscous damper. Background Art

[0002] Building dampers are safety devices installed on buildings to reduce wind loads or earthquake damage. They are widely used in civil buildings, industrial buildings, bridges, etc. The wind load in high-rise buildings has a very obvious disturbance on the structure. The damper can absorb and consume the horizontal shear force generated by the wind on the building structure to the maximum extent, effectively alleviating the impact and damage on the building structure.

[0003] However, the existing building dampers still have many defects. When the damper works continuously, the internal temperature will rise sharply, the damper silicone oil is prone to deterioration, and it also has a great impact on the seals, which need to be returned to the factory for replacement of new damping fluid or seals. Secondly, after the pin and the mounting plate are installed, the gap between the pin and the mounting plate is also a problem faced in the project. Utility Model Content

[0004] In order to solve: ① the problem that the internal temperature of the viscous damper rises under the reciprocating action of wind load, which has an adverse effect on the damping fluid and the seal; ② the problem that there is a gap between the pin shaft and the mounting plate after assembly, the utility model monitors the damper temperature in real time through an electric temperature control system, and drives the water cooling system of the solar photovoltaic system to control the temperature of the damper, so that the damper maintains a good working condition, and controls the pin shaft temperature through an electric auxiliary heating system, and eliminates the gap between the pin shaft and the mounting plate due to thermal expansion. The technical solutions adopted by the utility model are as follows:

The piston is provided with a channel with a continuously changing aperture, and bushings are provided at both ends of the energy consumption area, and the damping fluid is filled inside; the inner tube is a hollow steel pipe, which is plugged with the piston rod, and the open end of the inner tube is welded to the surface of the inner tube fixing plate, and the inner part of the inner tube is installed Water-cooling pipeline, the water-cooling pipeline extends outward from the pipeline maintenance area and is connected to the water cooling system. The electric temperature control system is installed on the surface of the oil cylinder and is used to monitor the real-time temperature of the viscous damper. The hollow pin shaft passes through the connecting hole of the pin head and the mounting plate. An electric auxiliary heating system is arranged inside the hollow pin shaft. The electric auxiliary heating system heats the hollow pin shaft to make it expand and maintain the corresponding temperature, so that the gap between the hollow pin shaft and the mounting plate is eliminated. The solar photovoltaic system is respectively connected to the electric temperature control system, the water cooling system, and the electric auxiliary heating system; the ear plate of the oil cylinder is fixed to the connecting plate of the pin head by bolts.

[0007] Furthermore, the piston rod and the inner tube are both round steel tubes with one end closed and the other end open.

[0008] Furthermore, the size of the channel at the maximum diameter is twice the size of the channel at the minimum diameter, and the channels are evenly distributed along the circumference of the piston.

[0009] Furthermore, the damping fluid is made of silicone oil, and the bushing is made of rubber polymer.

[0010] Furthermore, the ear plate and the connecting plate are fixed by using mounting bolts which are easy to disassemble.

[0011] Beneficial effects of the utility model:

[0012] The beneficial effects and advantages of the utility model are that the temperature of the damper is controlled by the solar photovoltaic system driving the water cooling system through the feedback signal of the electric temperature control system, so as to maintain the stable working performance of the damper. The pipeline inspection area is simple and convenient to disassemble, which is beneficial to the maintenance and inspection of the water cooling pipeline inside the inner cylinder. The channel with continuously changing aperture will cause the damping fluid to generate eddy currents in the channel, greatly improving the damping effect.
