The invention provides a flood prevention lifting type power distribution cabinet, which comprises supporting legs, air cylinders, an air pump, a power distribution cabinet body, lifting hinges, supporting leg guide rails, sealing pins, first vent holes and second vent holes. The supporting leg guide rails are fixedly connected on the supporting legs. The air cylinders are fixedly arranged at twoends of the supporting leg guide rails. Guide wheels are arranged in the supporting leg guide rail in a rolling manner. One end of the guide wheel is rotationally connected with the lifting hinges. Anair suction pipe is fixedly connected to the other side surface of the power distribution cabinet body. An air outlet of the air pump is fixedly connected with a telescopic hose. A piston is slidablyconnected to the inner wall of the cavity. The first vent holes are formed in the lower ends of the supporting legs. A sliding groove is formed in the middle sections of the first vent holes in a penetrating mode. The sealing pins are slidably connected to the inner wall of the sliding groove. The second vent holes are formed in the upper ends of the supporting legs. Due to the fact that the sealing pins are matched with the first vent holes, the automatic lifting of the power distribution cabinet can be achieved. Meanwhile, the situation that a circuit is short-circuited or damaged in the water can be avoided.
