The invention provides a deck efficient cleaning device for ships, and relates to the field of ships. The deck efficient cleaning device includes a moving mechanism, a sweeping mechanism, a transmission mechanism and an inclined supporting rod, the moving mechanism includes a moving supporting plate, a plurality of moving wheels and a hand push rod, the multiple moving wheels are fixedly installedat the bottom of the moving supporting plate, the surface of the hand push rod is fixedly connected with the upper surface of the moving supporting plate, the surface of the hand push rod is fixedlyconnected with a connecting cross rod, and the sweeping mechanism includes a cleaning rotating shaft, a telescopic air bag pipe and an air pump. According to the deck efficient cleaning device for theships, a rubber connecting pipe and a flexible iron wire are arranged, the flexibility of the cleaning structure is enhanced, during overexpansion in case of protrusion or impact, a room for bendingspringback exists, and thus the problems that when a general deck cleaning device is in use, self-adaptive deck corner cleaning is inconveniently adjusted, cleaning is prone to being obstructed by equipment and deck corners, and the cleaning efficiency is low are effectively solved.
