Climbing robot with adsorption structure

The invention relates to a climbing robot with an adsorption structure, and relates to the technical field of ship engineering auxiliary instruments. The climbing robot comprises a machine body, a cleaning device arranged on the machine body and used for polishing a ship surface, and an adsorption device arranged on the machine body and driving the machine body to be attached to the ship surface.An inner cavity is formed in the machine body. The adsorption device comprises a suction cup, a vacuum pipe, a negative pressure source and a pressure stabilizing valve. The suction cup is arranged onthe side, facing the ship surface, of the edge of an opening of the inner cavity. The vacuum pipe communicates with the inner cavity. The negative pressure source communicates with the vacuum pipe. The pressure stabilizing valve communicates with the inner cavity and is used for stabilizing gas pressure of the inner cavity. When the suction cup is attached to the ship surface, the cleaning deviceremoves old paint coatings
