The invention discloses an anti-skid bottom plate for a lifeboat, and relates to the technical field of fire fighting equipment. The anti-skid bottom plate for the lifeboat comprises a fixed plate, a water outlet pipe is fixedly installed in the center of the bottom of the fixed plate, a movable mechanism is arranged at the upper end of the fixed plate, a flow guide mechanism is arranged at the top of the fixed plate, and the movable mechanism comprises a connecting sleeve, a movable plate, an elastic piece, an anti-skid strip and a strip-shaped opening. The connecting sleeve is fixedly installed at the position, away from the center, of the top of the fixed plate, the movable plate is fixedly installed at the top of the connecting sleeve, the movable plate is movably installed at the upper end of the fixed plate through the elastic piece, and the elastic piece is fixedly installed at the bottom of the movable plate. According to the anti-skid bottom plate for the lifeboat, the movable mechanism and the flow guide mechanism are arranged, accumulated water at the top of the movable plate is quickly guided to the lower end and discharged from the water outlet pipe, and the situation that the accumulated water stops at the top of the movable plate, the anti-skid degree of the movable plate is reduced, and potential safety hazards are generated in the using process is avoided.
