Automatic pressure-regulating explosion-proof device of storage battery for explosion-proof forklift

Abstract

An automatic pressure-regulating explosion-proof device of a storage battery for an explosion-proof forklift comprises an automatic pressure-regulating explosion-proof device body arranged on a battery box. A pressure-regulating slider is arranged in an inner cavity of the automatic pressure-regulating explosion-proof device body, and the inner cavity of the automatic pressure-regulating explosion-proof device body is divided into two portions by the pressure-regulating slider, wherein one portion is a pressure chamber, and the other portion is a communicating chamber. The wall of the pressure chamber is provided with a high-pressure gas injection port, a sealing fastener is arranged in the high-pressure gas injection port, the communicating chamber is communicated with the inside of the battery box, the upper portion of the automatic pressure-regulating explosion-proof device body is provided with an exhaust port communicated with the atmosphere, the upper portion of the pressure-regulating slider contacts with the lower edge of the exhaust port, and a limiting block for limiting the pressure-regulating slider is arranged on the lower portion of the automatic pressure-regulating explosion-proof device body and contacts with the lower portion of the pressure-regulating slider. The automatic pressure-regulating explosion-proof device is simple and compact in structure, low in manufacture cost, capable of realizing automatic pressure regulation and reliable in operation.

Description

technical field [0001] The invention relates to an explosion-proof device for automatically regulating the voltage of a battery, in particular to an explosion-proof device for automatically regulating the voltage of a battery used in an explosion-proof forklift. Background technique [0002] Explosion-proof forklifts are widely used in petroleum, chemical, coal and other industries. When producing, concentrating, liquefying, storing and transporting flammable gases, they can reduce the probability of explosion and avoid casualties and property losses. For battery explosion-proof forklifts, the safety performance of batteries directly affects the safety performance of the entire explosion-proof forklift. [0003] The storage battery is often composed of multiple lead-acid batteries above 2V connected in series or in parallel, and placed in a battery combination in a metal battery box. The battery will generate gas during charging and discharging. When the gas concentration r...
