Abstract
A cable-direction-adaptive ROV winch applied to non-DP-equipped motherships, includes a non-DP-equipped mothership, an A-shaped support and a winch cable-drawing roller provided on the non-DP-equipped mothership, and an underwater vehicle. A pulley is rotatably connected to the A-shaped support, the underwater vehicle is connected to an umbilical cable, the umbilical cable passes around the pulley to be connected to the winch cable-drawing roller, and a locating unit for guiding the umbilical cable is provided on the non-DP-equipped mothership. The A-shaped support is provided with a rod. The pulley includes a sliding section and a rotating section, and the sliding section is annular and slides on the rod along a direction of the rod. The rod has a groove, and a bulge portion is formed on the sliding section. The rotating section is rotatably connected to an outer circle of the sliding section via a shaft bearing.
