Anti-explosion accumulator power supply unit

Abstract

The invention discloses an anti-explosion accumulator power supply unit comprising an upper box body, a lower box body, a box cover, a plurality of locking devices and a plurality of connecting rods. A dehydrogenation work bolt arranged on each lead-acid accumulator comprises a shell, a top cover, an air filter cup seat, an air filter cup, a first air filter sheet and a second air filter sheet. A gap is arranged between the outer wall of the air filter cup seat and the inner wall of a lower shell, dehydrogenation elements are internally arranged in the air filter cup, and the top cover is provided with another gap. The anti-explosion accumulator power supply unit has the advantage of reducing the usage space by utilizing a double-layer structure. The locking devices play the role of connecting, locating and fixing the upper box body and the lower box body, are convenient for the double-layer box body to be lifted synchronously or respectively; therefore, the anti-explosion accumulator power supply unit is convenient to use and is more suitable for underground emergency ventilation and charging rooms. Because the dehydrogenation work bolt is utilized, the hydrogen exhaust is reduced even eliminated, the leakage of water fog is completely avoided, and the use safety of the power supply unit is improved. The anti-explosion accumulator power supply unit can not only be taken as a traction power supply, but also taken as a fixed emergency power supply.

Description

technical field [0001] The invention relates to a power supply device, in particular to an explosion-proof storage battery power supply device. Background technique [0002] The design requirements of the explosion-proof battery power supply unit are based on the MT / T 334-2008 standard. The traditional explosion-proof battery power supply device has a single-layer structure, which requires a large space, and it is inconvenient to lift the box during transportation. Moreover, it can only be used as a traction power source for various locomotives, and is not suitable for use in underground emergency ventilation and charging rooms. [0003] The design requirements for explosion-proof batteries are based on the MT 658-1997 standard. Hydrogen gas will be generated during the use of lead-acid batteries, and the precipitated hydrogen gas and water mist will enter the special working plug together. The traditional explosion-proof battery power supply unit adopts a conventional wor...

AI Technical Summary

Problems solved by technology

The traditional explosion-proof battery power supply unit adopts a conventional working bolt, which is designed as a single-layer protection, which does not have the ability to eliminate hydrogen precipitation, and cannot completely prevent the overflow of water, resulting in a decrease in safe use performance

Since the precipitation of hydrogen gas cannot be eliminated, it cannot meet the use of the underground emergency ventilation charging room
