Underwater rope laying control device

The invention provides an underwater rope laying control device. The underwater rope laying control device comprises a supporting base body, a rotating part and a first brake device; the rotating partis used for winding a rope and is rotationally connected to the supporting base body; the first brake device is assembled on the rotating part and comprises a shell, a centrifugal part, an elastic part and a brake part; the centrifugal part is arranged in the shell in a sliding manner; the elastic part is arranged in a cavity, one end of the elastic part is connected to the centrifugal part, andthe other end is connected to the shell; the brake part is fixedly connected with the extending end of the centrifugal part; when the rotating speed of the rotating part of the underwater rope layingcontrol device is larger than the first rotating speed, the centrifugal part can drive the brake part to make contact with the supporting base body under the force of the rotating part to form a friction pair; and when the rota
