Embodiment 1

[0020] Reference figure 1 , 2 This embodiment includes an automatic pressure-regulating explosion-proof device body 3 provided on the battery box 2. A pressure-adjusting slider 7 is provided in the internal cavity of the automatic pressure-regulating explosion-proof device body 3. The pressure adjusting slider 7 will automatically adjust the pressure and the explosion-proof device The internal cavity of the body 3 is divided into two parts, one is the pressure chamber 8, the other is the communication chamber 9. The pressure chamber 8 is provided with a high-pressure gas injection port 10, and the high-pressure gas injection port 10 is provided with a sealing fastener 11 for communication The chamber 9 communicates with the inside of the battery box 2. The upper part of the automatic pressure-regulating explosion-proof device body 3 is provided with an exhaust port 4 that communicates with the atmosphere. The upper part of the pressure adjusting slider 7 is in contact with the lo...

Embodiment 2

[0028] Reference image 3 The difference between this embodiment and embodiment 1 is that: the pressure adjusting slider 7 is a hexahedral slider with a rectangular cross section; the limiting block and the automatic pressure regulating and explosion-proof device body 3 are an integral structure, and the limiting block is composed of A protrusion 12 provided at the lower part of the main body 3 of the automatic pressure regulating and explosion-proof device is replaced. The rest is the same as in Example 1.

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 automatic voltage regulation and explosion-proof device for a battery, in particular to an automatic voltage regulation and explosion-proof device for an explosion-proof forklift. Background technique [0002] Explosion-proof forklifts are widely used in petroleum, chemical, coal and other industries. When producing, concentrating, liquefying, and storing and transporting flammable gases, they can reduce the probability of explosion and avoid casualties and property losses. For the battery explosion-proof forklift, the safety performance of the battery directly affects the safety performance of the entire explosion-proof forklift. [0003] Batteries are often a combination of multiple lead-acid batteries above 2V in series or in parallel and placed in a metal battery box. The battery will produce gas during the charging and discharging process. When the gas concentration reaches a certain level, the pressure in the battery box wil...
