Explosion-proof electrical cabinet

Abstract

The invention discloses an explosion-proof electrical cabinet, which includes a main cabinet body. The main cabinet body is provided with an inflatable tube; one side of the main cabinet body is fixedly connected to a ventilation cabinet body; the main cabinet body and the ventilation cabinet body are communicated through a communication hole; a first sealing plate is fixedly connected to the piston rod of a first cylinder; the first sealing plate is pushed by the first cylinder to block the communication hole; the upper side of the ventilation cabinet body is provided with a mounting groove;one side in the mounting groove is rotarily connected with a cover plate; the inner bottom of the mounting groove is provided with a vent; the piston rod of a second cylinder pushes a second sealing plate to move up and down to block the vent; the upper end of the vent is fixedly connected with a filter net; and a cleaning device is connected to the bottom of the cover plate. The explosion-proof electrical cabinet has the advantages that when the cover plate is rotated to be opened, a connecting rod swings and pulls a first rotating shaft to slide along a waist chute, and through enabling a gear to rotate and enabling the first rotating shaft to rotate, a cleaning roller rotates to clean the filter net, and the dust accumulated on the filter net is thus quickly cleaned.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an explosion-proof electrical cabinet. Background technique [0002] Explosion-proof electrical cabinets are often used in production sites where explosive gases are mixed, and explosion-proof distribution boxes will inevitably generate sparks during work. Once the sparks in the explosion-proof distribution box come into contact with explosive gases in the production site, it will It will cause an explosion, cause serious production accidents, and bring huge economic losses and casualties. [0003] When the electric cabinet in the prior art is ventilating, the flammable and explosive gas from the outside easily enters the ventilating cabinet body, and the filter on the ventilating port is easy to accumulate dust, which is not easy to clean and affects the ventilation effect. Contents of the invention [0004] The object of the present invention is to propose an exp...
