The invention discloses a propeller device and a ship comprising the same, the propeller device comprises a propeller body and an energy-saving assembly, the propeller body and the energy-saving assembly are used for being installed at the stern end and the stern respectively, and the energy-saving assembly is arranged close to the propeller body in the length direction of the ship; the energy-saving assembly comprises a guide pipe extending in the length direction of the ship and a plurality of stator blades, the axial section of the guide pipe is in a wing shape, the guide pipe is provided with an opening in the radial direction, the edge, corresponding to the opening, of the guide pipe is used for being connected with the ship, and the stator blades are arranged on the stern of the ship in a surrounding mode. The projections of at least part of the stator blades in the length direction of the ship are located in the projection range of the guide pipe, and the stator blades located in the projection range of the guide pipe are close to the propeller body relative to the guide pipe. Separation of water flow at the tail of the ship is reduced through the guide pipe, flow field uniformity is improved, the stator blades change the flow direction of the water flow at the tail of the ship, the propeller body obtains larger thrust, and propelling efficiency is improved.

    本发明公开了一种螺旋桨装置及包含其的船舶,螺旋桨装置包括螺旋桨本体和节能组件,螺旋桨本体和节能组件分别用于安装在船尾端部和船尾上,节能组件在船舶的长度方向上临近螺旋桨本体设置;该节能组件包括沿船舶的长度方向延伸的导管和多个定子叶片,导管的轴向截面形状为翼型,导管在其径向方向上开设有开口,导管对应开口的边缘用于连接船舶,多个定子叶片环绕设置在船舶的船尾上,至少部分定子叶片在船舶的长度方向上的投影位于导管投影范围内,且位于导管投影范围内的定子叶片相对导管靠近螺旋桨本体设置。通过导管减小船体尾部水流的分离,提高流场均匀性,定子叶片改变船体尾部水流的流向,使螺旋桨本体获得更大推力,提升推进效率。
