The invention discloses an energy-saving vortex-eliminating boosting impeller device behind a ship propeller. The device comprises a circular truncated cone and a guide pipe, wherein a plurality of hydrofoils are uniformly arranged on the outer circumferential surface of the guide pipe; the small-diameter end of the circular truncated cone is fixedly connected with a cylinder, a plurality of rectifying fins are fixedly connected to the circumferential surface of the circular truncated cone and the circumferential surface of the cylinder at equal intervals and installed in the guide pipe in a penetrating mode, the connected cylinder end is flush with one end face of the guide pipe, and the connected circular truncated cone end extends out of the other end face of the guide pipe by the length L. The energy-saving vortex-eliminating boosting impeller device for the ship is of a ship body accessory structure, a flow field behind a ship propeller can be well improved, a hub vortex behind the propeller is diffused, the total torque of the propeller is reduced, the thrust of the propeller is improved, noise pollution is reduced, the energy loss of rotating wake flow behind the propeller is recycled, and the energy-saving and emission-reducing effects are achieved.

    本发明公开了一种船舶桨后节能消涡助推叶轮装置,包括圆台和导管,所述导管外圆周面上均等设置有若干个水翼,所述圆台的小直径端固定连接有圆柱体,所述圆台和圆柱体的圆周表面上均等固定连接有若干个整流鳍片,且穿装在所述导管内,其中,相连接的圆柱体端与导管一端面平齐,相连接的圆台端伸出导管另一端面长度L。本发明一种船舶节能消涡助推叶轮装置为船体附属结构,能够较好地改善船舶螺旋桨后的流场,扩散螺旋桨后方的毂涡,降低螺旋桨的总扭矩,提高螺旋桨的推力,减少噪声污染,回收了螺旋桨后旋转尾流的能量损失,并起到节能减排效果。
