The invention discloses an unmanned ship propeller anti-winding device, which belongs to the technical field of ship propellers, and comprises a shell, a first paddle part, a second paddle part and a driving part for driving the first paddle part and the second paddle part to coaxially rotate, the driving part comprises a constant-speed differential mechanism and a differential driving mechanism; two output shafts of the constant-speed differential mechanism rotate in a differential manner; the differential driving mechanism is driven by the differential of the two output shafts; the first paddle part comprises a first paddle area and a rotary cutting mechanism; the second paddle part comprises a second paddle area and a commutator; and the rotary cutting mechanism is mounted between the first paddle area and the second paddle area. According to the invention, the linkage type constant-speed differential mechanism and the differential driving mechanism are adopted, and when the propeller is blocked by foreign matters, the differential driving mechanism can be started by the speed difference between the two rotating blades, so that the spiral blade arranged between the two rotating blades is automatically unfolded and rotated, and the foreign matters adhered between the two rotating blades are removed; and the requirement of personnel maintenance is reduced.

    本发明公开了一种无人船舶螺旋桨防缠绕装置,属于船舶螺旋桨技术领域,包括外壳,还包括由第一桨叶部、第二桨叶部及驱动第一桨叶部与第二桨叶部共轴旋转的驱动部;所述驱动部包括有两个输出轴差速转动的等速差速器以及通过两个输出轴的差速驱动的差速驱动机构;所述第一桨叶部包括有第一桨叶区与旋转切割机构;所述第二桨叶部包括有第二桨叶区与换向器;所述旋转切割机构安装于第一桨叶区与第二桨叶区之间。本发明中,采用了联动式等速差速器与差速驱动机构,当受到异物阻碍时,两个转动桨叶之间的速度差值会启动差速驱动机构,使设置于两个转动桨叶之间的螺旋刀片自动展开并旋转,用以清除两个转动桨叶之间沾附的异物,减少人员维护的需求。
