Overheat self-opening type power distribution cabinet based on hot metal sheet

Abstract

The invention relates to the technical field of power distribution cabinets, and discloses an overheat self-opening type power distribution cabinet based on a hot metal sheet. The cabinet comprises acabinet body, a groove body is formed in the cabinet body, a thermal bimetallic strip is fixedly installed at the left end of the groove body, a connecting rod is fixedly installed at the right end ofthe thermal bimetallic strip, the right end of the connecting rod is fixedly installed at the eccentric position of a rotating gear, and a movable toothed plate corresponding to the rotating gear ismovably installed at the bottom end of the groove body. According to the overheat self-opening type power distribution cabinet based on the hot metal sheet, the thermal bimetal sheet is heated to deform and drives the connecting rod to move, the connecting rod drives the rotating gear to rotate, the rotating gear drives the movable toothed plate at the lower end to move, the movable toothed platedrives the rotating rod at the right end to move, the rotating rod drives a baffle plate at the top end of the rotating rod to move at the lower end of a fire extinguishing device in the moving process, and when the baffle plate moves to the right end, the fire extinguishing material falls into the power distribution cabinet to extinguish fire, so that the effect of automatically triggering the fire extinguishing device to extinguish fire is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an overheating self-opening power distribution cabinet based on hot metal sheets. Background technique [0002] Power distribution cabinets can be divided into power distribution cabinets and lighting distribution cabinets, which are the final equipment of the power distribution system and the general name of the motor control center. The electric energy of a certain circuit of the equipment is distributed to the nearby loads to provide protection, monitoring and control for the loads. While using the power distribution cabinet, some new materials are also used. For example, thermal bimetals and thermal bimetals are often used. Metals are composite materials consisting of two or more metals or metal composite elements with different coefficients of thermal expansion firmly held together, which deform when heated. [0003] In the power cabinet, there will be c...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an overheated self-opening power distribution cabinet based on hot metal sheets, which has the advantages of timely extinguishing the fire source and automatically opening the cabinet door after the fire source is extinguished, and solves the problem of the current distribution cabinet. When the electric cabinet encounters a fire, it cannot control the fire in time, and opening the door when a fire is discovered is a problem that causes secondary damage
