The invention discloses a ship propeller capable of preventing water plant winding. The ship propeller comprises a ship body. A propelling device is arranged at the tail part of the ship body and comprises a first shifting plate which is rotatably arranged on the lower end surface of the tail part of the ship body; a second shifting plate and a third shifting plate are arranged on the right side of the first shifting plate; connecting grooves are formed in the right end surfaces of the first shifting plate and the second shifting plate; connecting blocks are rotatably arranged between the upper walls and the lower walls of the connecting grooves; the right ends of the connecting blocks extend outwards and are fixedly connected to the left end of the second shifting plate or the left end ofthe third shifting plate. A reciprocating motion device is arranged in the propelling device; a locking device is arranged in the tail part of the ship body. According to the invention, the ship is pushed to move forward through the reciprocating swing of the shifting plates in a tail-swinging advancing mode of bionic fishes, so that the situation that the ship fails to work on the water surfacebecause the rotary propellers such as propellers are wound by water plants or fishing nets in the advancing process of the ship is avoided; the advancing is stable, the noise is low, and organisms inthe water are not damaged.

    本发明公开的一种防水草缠绕的船舶推进器,包括船体,所述船体尾部设有推进装置,所述推进装置包括可转动的设于所述船体尾部下端面的第一拨板,所述第一拨板右侧设有第二拨板和第三拨板,所述第一拨板和所述第二拨板的右端面设有连接槽,所述连接槽上下壁之间可转动的设有连接块,所述连接块的右端延伸至外且固定连接于所述第二拨板或所述第三拨板的左端,所述推进装置内设有往复运动装置,所述船体尾部内设有锁定装置,本发明通过仿生鱼类的摆尾的行进方式,以拨板的往复摆动推动船舶行进,使得船舶在行进过程中不会出现螺旋桨等旋转式推进器被水草或是渔网缠绕导致船舶瘫痪在水面的情况,行进稳定,噪音小,且不会对水中的生物造成伤害。
