The invention relates to the technical field of hovercraft, in particular to an overwater
wind power project maintenance hovercraft. According to the technical scheme, the ship comprises a ship body, ship fixing structures, reinforcing structures and unfolding structures. An
assembly frame is arranged on the side wall of the ship body; the unfolding structure comprises a
stroke frame, a rotating shaft, a hollow arm, a second motor, a driving shaft, a first sleeve
bevel gear and a second
bevel gear. The ship fixing structure comprises a mounting frame, a motor I, a screw rod, a nut, a clamping frame, a supporting arm I, a supporting arm II, a rotating seat I, a rotating seat II, a nut, a rotating seat III and a rotating seat IV; the reinforcing structure comprises a first clamping arm and a second clamping arm. By arranging the unfolding structure, the ship fixing structure, the reinforcing structure and the sealing support, accurate stopping and stable fixing of
wind power tower barrels of different specifications are achieved, meanwhile, the sealing performance, safety and operation convenience of offshore operation are guaranteed, and the overwater
wind power overhaul efficiency is improved.
