Abstract
The utility model relates to the technical field of power driving devices for ships, in particular to an anti-twining driving device for the ships. The anti-twining driving device for the ships comprises a propeller, a transmission shaft and a ship stern tube or a Y-shaped tail stand. The anti-twining driving device for the ships is characterized in that a sawtooth-shaped tubular cutting tool is arranged, the cutting tool is mounted on the outer wall of the ship stern tube or the Y-shaped tail stand, the cutting edge of the sawtooth-shaped cutting tool faces the propeller, the rear end face of the propeller is provided with a cutting strip knife, the side face of the cutting strip knife is provided with a cutting edge, and the cutting strip knife is parallel to the transmission shaft of the propeller. According to the anti-twining driving device for the ships, two-stage cutting can be realized by utilizing the rotation of the propeller, the cutting strip knife rotates along with the propeller to cut a linear object close to the propeller, and once the linear object is close to the transmission shaft, the sawtooth-shaped tubular cutting tool automatically cuts the linear object. The anti-twining driving device for the ships has the advantages of being simple in structure, thorough in cutting, high in working efficiency of the propeller and the like, and can be applied to various ships to prevent failures due to the fact that linear objects are twined around the propeller.
