The ship propeller rear trailing vortex recovery device is arranged at the tail of a ship body, a propeller and a rudder horn are arranged at the tail of the ship body, and the rudder horn is located behind the propeller; the rudder horn is provided with a free impeller which can passively rotate when the propeller rotates, and the free impeller is located between the rudder horn and the propeller; the free impeller comprises a free impeller hub part and free impeller blades fixedly arranged on the free impeller hub part; the hub part of the free impeller is not in contact with the propeller hub; the rotation axis of the free impeller hub part coincides with the rotation axis of the propeller hub; and the diameter of the free impeller is not smaller than that of the propeller. The free impeller is arranged on the rudder horn, the free impeller does not need to be driven by a power device and is only driven by the wake flow of a part of the recycled propeller in the paddle disc face, and the better energy-saving effect is achieved.

    本发明公开了一种船舶用桨后尾涡回收装置,其设于船体尾部,船体尾部设有螺旋桨和挂舵臂,挂舵臂位于螺旋桨后方;挂舵臂上设有可在螺旋桨旋转时被动旋转的自由叶轮,自由叶轮位于挂舵臂和螺旋桨之间;自由叶轮包括自由叶轮毂部和固设于自由叶轮毂部的自由叶轮叶片;自由叶轮毂部和螺旋桨桨毂不接触;自由叶轮毂部的旋转轴线和螺旋桨桨毂的旋转轴线重合;自由叶轮的直径不小于螺旋桨的直径。本发明在挂舵臂上设置自由叶轮,该自由叶轮无需动力装置进行驱动,仅靠桨盘面内部分回收螺旋桨尾流驱动,实现了更好的节能效果。
