One or more embodiments of the invention provide an anti-winding device for a ship rotating shaft. The device comprises a stern tube arranged at a stern part, and a cutter assembly fixedly arranged atthe port of the stern tube; a propeller hub is arranged in the stern tube; a propeller is arranged at the end of the propeller hub; the cutter assembly comprises a disturbance rod parallel to the axis of the propeller hub and a chain saw arranged on the outer wall of the stern tube, the disturbance rod is arranged at the end of the stern tube and performs planetary rotation with the propeller hubas the axis, the chain saw is in power connection with the disturbance rod, and when the disturbance rod rotates, the chain saw cuts entanglements through rotation. The cutter assembly is arranged and comprises the disturbance rod and the chain saw, and the propeller hub and the propeller can be protected before winding; and if winding cannot be avoided, the disturbance rod and the chain saw cutoff and remove the entanglement, so that the propeller hub gets rid of winding.
本说明书一个或多个实施例提供一种船舶转动轴用防缠绕装置,包括:设于船艉部的艉管、固定设于艉管端口处的切刀组件,艉管的内部设有桨毂,桨毂的端部设有螺旋桨,切刀组件包括平行桨毂的轴线的扰动杆、以及设于艉管外壁上的链条锯,扰动杆设于艉管的端部,以桨毂为轴线做行星转动,链条锯与扰动杆动力连接,当扰动杆转动时,链条锯通过转动来切割缠绕物。本发明设有切刀组件,包括扰动杆和链条锯,能够在未缠绕之前对桨毂以及螺旋桨实施保护;若无法避免缠绕的情况,扰动杆和链条锯将缠绕物切断并清除,使桨毂摆脱缠绕。
