Robot mechanism applicable to marine organism cleaning of jacket

The utility model relates to a robot mechanism applicable to marine organism cleaning of a jacket. The robot mechanism consists of a suction cup, a frame structure, a universal joint, a surrounding type clamping jaw, high-pressure nozzles and a scissor support, wherein a robot is lifted into water through a platform crane, the suction cup is sucked on a stand column of the jacket through a control terminal, the surrounding type clamping jaw surrounds the stand column of the jacket through driving of a screw of the scissor support, the high-pressure nozzles are started, high-pressure water passes through the nozzles to perform high-pressure water cleaning on marine organisms on the stand column, meanwhile, the control terminal cancels the suction of the suction cup, and the robot is controlled to move by the high-pressure water of the upper and lower high-pressure nozzles on the surrounding type clamping jaw. According to the robot mechanism, the specially-shaped robot is adopted, damage to a diver caused by c
