titleOfInvention A mine explosion-proof charging device
abstract The invention discloses an explosion-proof charging device for mining, comprising an explosion-proof box and a charging circuit arranged in the explosion-proof box. The charging circuit includes a main circuit, a control circuit and a DC charging module respectively connected to the main circuit. The DC charging module is connected to external electrical equipment; the main circuit is connected with two input power sources for underground charging and ground charging, respectively, and the control circuit controls the main circuit to charge the electrical equipment through the DC charging module. The mine explosion-proof charging device of the invention can realize charging in two different occasions, underground and on the ground.
