Fire extinguishing auxiliary device for alternating-current distribution cabinet in case of fire

Abstract

The invention relates to the technical field of alternating-current distribution cabinet protection and discloses a fire extinguishing auxiliary device for an alternating-current distribution cabinetin case of a fire. The fire extinguishing auxiliary device comprises a distribution box main body, a connecting shaft and an arc-shaped track, a motor is arranged in the distribution box main body, the motor is rotatably connected with the connecting shaft, the left end of the arc-shaped track is fixedly connected with an extrusion part, the left end of the extrusion part is provided with an elastic air bag, and the bottom of the distribution box main body is provided with a collection air bag. A rotating piece is driven to rotate through the connecting shaft and moves on the arc-shaped trackto enable the arc-shaped track to drive the extrusion part to move left and right; the elastic air bag is extruded, the compressed collection air bag expands to suck air through a collecting pipe, andairflow is generated at the upper end of the collecting pipe to collect falling dry powder; the effect of collecting the dry powder is achieved through the air bag structures while the dry powder falls down during fire extinguishing, accumulation of the dry powder in the power distribution cabinet after fire extinguishing is avoided, the power distribution cabinet is sealed when a fire occurs, and the dry powder is prevented from being sprayed into air during fire extinguishing.

Description

technical field [0001] The invention relates to the technical field of AC power distribution cabinet protection, in particular to an auxiliary fire extinguishing device for an AC power distribution cabinet when a fire occurs. Background technique [0002] The AC power distribution cabinet is the terminal equipment of the power distribution system. The main switch for controlling the power equipment is set in the power distribution cabinet. With more and more integrated circuits in the power distribution cabinet, a large amount of heat is generated during operation. Therefore It is very easy to cause an internal short circuit and cause a fire. The current power distribution cabinets are equipped with fire extinguishing devices, and dust such as dry powder is generally used to extinguish fires. When extinguishing a fire, it enters the air through the vent and pollutes the air. In order to solve the above problems, a fire extinguishing auxiliary device for an AC power distribut...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the invention provides an auxiliary fire extinguishing device for AC power distribution cabinets in case of fire, which automatically activates dry powder to extinguish fires, collects the dry powder after fire extinguishing, and closes the communication between the power distribution cabinet and the outside air. Advantages, solve the problem of dust accumulation in the power distribution cabinet, dust entering the air and polluting the environment
