Electrical engineering self-cleaning rapid heat dissipation safety electrical cabinet

The invention provides an electrical engineering self-cleaning rapid heat dissipation safety electrical cabinet, and solves the problems that in the prior art, a high-pressure spray head can only move up and down to carry out high-pressure washing in the vertical direction on the surface of an electrical element, and direction adjustment cannot be carried out to carry out comprehensive washing on the top and the bottom of the electrical element. Comprising a cabinet body with an opening in the front side, a reciprocating semicircular sliding rail with the inner side face facing the inner wall of the rear side of the cabinet body is fixedly installed on the top face in the cabinet body, a reciprocating sliding block is slidably installed in the reciprocating semicircular sliding rail, a reciprocating sliding plate is fixedly connected to the bottom of the reciprocating sliding block, and a cleaning water pipe is fixedly connected to the bottom face of the reciprocating sliding plate; a plurality of cleaning no
