The invention relates to the technical field of ship equipment, and discloses an anti-winding ship tail shaft which comprises a sealing end cover, the middle of the sealing end cover is movably sleeved with a tail shaft, the outer side of the middle of one end of the sealing end cover is movably sleeved with a connecting piece, and one end of the connecting piece is fixedly connected with a movable ring. Through the arrangement of a connecting rod, a cutter and a fixing disc, when a fishing net, a rope and other foreign matter are wound on the tail shaft, the foreign matter is wound on the connecting rod on the outer side of the tail shaft, and the foreign matter is wound on the tail shaft more and more tightly after being wound, so that the connecting rod is pressed to be close to the tail shaft, and a sliding ring at the other end of a pull rope moves leftwards under the action of a reset spring; the bevel slope surface of the sliding ring can push the rotating block to rotate, so that the cutter rotates by a certain angle, the cutter cuts the aquatic plants wound on the tail shaft in the rotating process, and the risk that the propeller is affected by winding of the aquatic plants is reduced.

    本发明涉及船舶设备技术领域,且公开了一种防缠绕的船舶艉轴,包括密封端盖,所述密封端盖的中部活动套接有艉轴,所述密封端盖一端中部的外侧活动套接有连接件,所述连接件的一端固定连接有活动环。通过连接杆、刀具、固定盘的设置,当艉轴上缠绕有渔网、绳索等异物时,异物将缠绕在艉轴外侧的连接杆上,而异物缠绕之后会在艉轴上越缠越紧,从而压迫连接杆向艉轴靠近,使得拉绳另一端的滑动圈在复位弹簧的作用下向左侧移动,滑动圈的斜口坡面能够推动转动块旋转,从而使得刀具旋转一定角度,刀具在旋转的过程中对缠绕在艉轴上的水草实现切割,从而降低推进器受水草缠绕影响的风险。
