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 of the ship 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 and a plurality of stator blades, the guide pipe extends in the length direction of the ship, 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 the stator blades in the length direction of the ship are all located outside the projection range of the guide pipe. Separation of water flow at the tail of the ship body can be reduced through the guide pipe, the uniformity of a flow field is improved, the stator blades can generate water flow direction beneficial to the propeller body, the propeller body obtains larger thrust, and the propelling efficiency is improved.
本发明公开了一种螺旋桨装置及包含其的船舶,该螺旋桨装置包括有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舶的船尾端部和船尾上,节能组件在船舶的长度方向上临近螺旋桨本体设置;该节能组件包括有导管和多个定子叶片,导管沿船舶的长度方向延伸,且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,多个定子叶片在船舶的长度方向上的投影,均位于导管的投影范围之外。通过导管可以减小船体尾部水流的分离,提高流场的均匀性,定子叶片可以产生有利于螺旋桨本体的水流流向,使得螺旋桨本体获得更大的推力,提升推进效率。
