Description

Pure electric movable miniature explosion-proof fire station

Technical Field

The invention relates to the technical field of fire fighting, in particular to a pure electric mobile miniature explosion-proof fire station.

Background

At present, a common fire engine is generally driven by fuel oil and has larger volume; when a fire breaks out, the time from the fire brigade to the fire scene is generally more than 20 minutes. Wherein, in the same positions of old districts, factories and rural huhu, the big fire engine can not enter, which brings disadvantages for extinguishing fire and rescuing the life and property safety of people. In order to respond to the national call, the fire disaster is taken as 'early rescue', 'small extinction' and 'three minutes arrival', and the existing fire-fighting tools can not meet the requirement.

At present, the fire fighting equipment fire fighting pump power sources generally have three kinds, which are respectively: the motor is driven, the gasoline engine or the diesel engine is driven, and the compressed gas is driven. The compressed gas drive has short working time due to the volume of the gas cylinder, and is mainly used for general small-sized fire. Gasoline or diesel driven generally have large volume and heavy self weight, and are often powered by a hand-lifting pump, because the weight of the gasoline or diesel driven generally is too heavy and the gasoline or diesel driven generally is not flexible enough in use, and moreover, sparks generated when a gasoline engine or a diesel engine works can cause secondary disasters to disaster relief sites with flammable and explosive gases or dust. In addition, the exhaust gas exhausted in the closed environment has great harm to the fire fighters. In addition, when the traditional direct current brush motor works, electric sparks are always generated due to friction between the commutator and the carbon brush, which is a very fatal defect in the environment with inflammable and explosive gas and dust, and a secondary accident is easily caused.
