A turbine type viscous damper

Abstract

The invention discloses a turbo type viscous damper. The turbo type viscous damper comprises a base; the base is provided with a cylindrical steel basin; the steel basin comprises a steel basin side wall, a steel basin top plate and a steel basin bottom plate; the steel basin is filled with viscous damping liquid; rolling bearings are arranged in the center of the steel basin top plate and the center of the steel basin bottom plate; a rotating shaft is arranged between the rolling bearings through rotating shaft bolts; the upper end of the rotating shaft protrudes from the steel basin top plate; the rotating shaft is provided with a plurality of blades; the upper end of the rotating shaft is provided with a steel wire rope plate; a torsion spring is connected between the steel wire rope plate and the steel basin top plate; one end of the torsion spring is arranged on the steel basin top plate; the other end of the torsion spring is arranged on the steel wire rope plate; and a pluralityof steel wire ropes are wound around the steel wire rope plate. The turbo type viscous damper is convenient to use, and the problems that existing piston type viscous dampers are short in stroke, high in internal pressure and machining precision of a cylinder body and a piston, prone to oil leakage, large in size, high in manufacturing cost and complicated to mount are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a turbine type viscous damper. Background technique [0002] Viscous dampers have been widely used in many fields such as civil engineering and construction engineering. The mechanism is to use the viscosity of the damping liquid to convert the energy of the structure into heat energy and dissipate it in high-speed flow, so as to buffer the impact of external loads and protect the structure. security purposes. [0003] At present, the viscous damper commonly used in the field of civil engineering is a piston type, and the core components are oil cylinders and pistons. Its working principle is that through the reciprocating movement of the piston in the cavity, the viscous damping liquid is squeezed through the small oil hole on the piston or the gap between the piston and the inner wall of the cylinder, and the absorbed energy is converted into heat energy ...
