Fire-fighting electrical leakage detection device

The utility model provides a fire-fighting electrical leakage detection device which comprises a leakage detector, the outer side surface of the leakage detector is fixedly connected with a grip, the outer side surface of the leakage detector is fixedly connected with an indicating lamp, the outer side surface of the leakage detector is rotatably connected with a knob, and the knob is fixedly connected with the grip. And one end of the electric leakage detector is fixedly connected with an inductive head. According to the fire-fighting electrical leakage detection device, through arrangement of a limiting groove, a positioning groove, a telescopic spring, a positioning column, a limiting block, a positioning hole, a pressing block, a loudspeaker, a screw rod and a pull ring, when a battery needs to be replaced, the limiting block slides into the limiting groove firstly, and when the limiting block slides to a certain position, the limiting block extrudes the positioning column and the telescopic spring, so th
