[0088] The plurality of shock absorbers 11 are fixed on the support through the casing.

[0089] Preferably, the elastic member includes a spring and a sliding plate, and the middle part of the sliding plate has a hole through which the transmission shaft 3 passes;

[0090] The spring is sleeved on the outside of the damping member;

[0091] The sliding plate is arranged at both ends of the spring....

Embodiment 2

[0115] (1) Shock absorbing device

[0116] Such as figure 1 As shown, when the damping device is used for electrical equipment 12, it is installed between the equipment and its bracket. A support mechanism 10 is fixed at the center of the support top plate by welding or bolts on the top of the support, and the electrical equipment 12 falls on the support mechanism 10, which is preferably a cylinder. The shock absorber 11 is arranged on the outer ring of the support mechanism 10. The number of shock absorbers 11 should be consistent with the number of mounting holes in the bottom flange of the electrical equipment 12. The diameter of the bolt rod of the shock absorber 11 should match the opening of the bottom flange of the electrical equipment 12. Shock absorber 11 device body passes support top plate perforation, and shock absorber 11 outer tube wall has screw thread, shock absorber 11 and support are fixed by respectively two pieces of special nuts on the support top plate. ...

Embodiment 3

[0232] The present invention based on the same inventive concept also provides a method for designing a shock absorber, including:

[0233] Determining the position and number of the shock absorbers 11 based on the parameters of the electrical equipment 12 arranged on the support mechanism 10;

[0234] Determine the design trigger force of each shock absorber 11 based on the parameters of the electrical equipment 12 and seismic fortification requirements and the position and quantity of the shock absorbers 11;

[0235] The type of the shock absorber 11 is determined by the design trigger force of the shock absorber 11;

Abstract

The invention provides a shock absorber and a design method of the shock absorber, including: a support mechanism (10) and a plurality of shock absorbers (11); the shock absorber (11) includes a shell, located The energy dissipation element inside the housing, the elastic member, and the transmission shaft (3) passing through the housing and the elastic member in turn; the support mechanism (10) is arranged in the middle of the bottom of the electrical equipment (12), and the plurality of shock absorbers (11) is fixed to the electrical equipment (12) through the transmission shaft (3). The invention dissipates the earthquake energy through the operation of the energy-consuming element, and increases the shock-absorbing effect; after the earthquake action disappears, the elastic member can help the electrical equipment (12) restore the original state.

Description

technical field [0001] The invention relates to an anti-seismic safety protection technology for electric facilities, in particular to a shock absorbing device and a design method of the shock absorbing device. Background technique [0002] Due to the uneven distribution of energy bases and power loads, a large number of substations (conversion) stations need to be built in unfavorable areas with high seismic intensity. More than 60% of the key equipment in the substation (converter) station are pillar electrical equipment (12) (circuit breakers, transformers, etc.). Such equipment usually uses porcelain materials to ensure insulation performance, and equipment to meet electrical clearance requirements The structure is thin and high, and it is difficult to take into account the seismic performance in design and manufacture, so the earthquake damage of pillar equipment is serious. [0003] The traditional shock absorbing device dissipates the seismic energy introduced into t...
