Shock-resistant damper used for electromechanical device

Abstract

The invention discloses a shock-resistant damper used for an electromechanical device. The shock-resistant damper comprises a first connecting base, a second connecting base, a spring unit and dampingoil, wherein the first connecting base is connected with the electromechanical device, the second connecting base is connected with a building body, the spring unit is arranged between the first connecting base and the second connecting base, and the first connecting base is connected with the second connecting base through the spring unit. A second sleeve is arranged on the second connecting base and connected with the second connecting base, the second sleeve is connected with the first connecting base through a telescoping connecting piece, and the damping oil is introduced into the secondsleeve. According to the shock-resistant damper used for the electromechanical device, the shock-resistant damper as a medium for making the electromechanical device connected with the building body,the spring unit and the second sleeve can bear the load which changes constantly and the load of super-large external force, a damping effect on the accelerated speed generated by the load which changes constantly and the load of the super-large external force can be achieved through the damping oil, the safety of the electromechanical device is comprehensively protected, and the occurrence rateof accidents is reduced.

Description

technical field [0001] The invention relates to an anti-seismic damper for electromechanical equipment. Background technique [0002] The earthquake resistance of electromechanical equipment is an emerging industry in China. The national mandatory specification GB50981 "Code for Seismic Resistance of Building Electromechanical Engineering" has clearly stipulated that construction electromechanical equipment such as: generator sets, transformers, batteries, power capacitors, distribution boxes, distribution cabinets, fire protection Equipment and other building mechanical and electrical equipment need to be protected against earthquakes. However, there is no detailed description in the specification on how to carry out the seismic design and whether it can well solve the problem of seismic protection of equipment. Due to the importance of anti-seismic equipment and the advocacy of national regulations, related anti-seismic protection products for electromechanical equipment ...

AI Technical Summary

Problems solved by technology

However, this type of spring anti-seismic device is only limited to the role of rigidity in the level of anti-seismic protection. Its steel wall structure is used to resist earthquake force, which is a relatively simple and rough solution.

At the same time, the device does not have the functions of shock isolation and energy dissipation. For some mechanical and electrical equipment with low rigidity, if the earthquake force is too large, the equipment will be damaged due to its own insufficient stiffness, even if the device can withstand the earthquake force. However, due to the excessive seismic acceleration acting on the electromechanical equipment, the equipment has also been damaged, so the device cannot achieve a good effect of earthquake protection
