Abstract

The invention relates to an anti-explosion special type power supply device and belongs to the technical field of storage batteries. The device is characterized in that a bonding conductor sheath is sleeved on a bonding conductor, a box cover is in a double-layer structure and composed of an upper layer cover plate and a lower layer cover plate, the top periphery of a power supply box body and the peripheries of the upper layer cover plate and the lower layer cover plate are in an inclined plane structure, a plurality of ventilating slots are respectively arranged on the upper layer cover plate and the lower layer cover plate, and the ventilating slots of the upper layer cover plate and the ventilating slots of the lower layer cover plate are distributed in a staggered mode. According to the anti-explosion special type power supply device, a lead-acid storage battery with an explosion suppression performance is utilized so that the explosion suppression performance is improved, the bonding conductor sheath capable of preventing dusts is utilized so that a hidden danger of the explosion caused by the fact that combustible dusts are ignited due to overhigh local temperature or electric sparks of the bonding conductor is eliminated, a dustproof type power supply box body and a box cover structure are utilized, so that a hidden danger that gathered dusts can be ignited is eliminated, besides, the safety performance of a dust anti-explosion vehicle in a running process is improved, and the safety of persons and properties of operators on site can be guaranteed.

Description

technical field [0001] The invention relates to an explosion-proof special power supply device, in particular to an explosion-proof special power supply device for forklifts, and belongs to the technical field of storage batteries. Background technique [0002] As a kind of logistics handling, loading and unloading, and stacking machinery, forklifts are used in more and more fields and places. However, in many industries and units such as chemical industry, coal, cement and flour processing, combustible dust that may be generated in the process of production, filling and storage and transportation is mixed with air to form an explosive mixture, making these areas unsuitable for ordinary forklifts. entered area. Dust explosion-proof forklifts are specially designed and produced for places where explosive dust may be generated. The special power supply device for dust environments is used as electric traction vehicles in combustible dust environments in factories (except for ...
