The invention discloses a propeller device and a ship, and relates to the technical field of ship manufacturing. The propeller device comprises a propeller body, and the propeller body is used for being installed at the stern end of the ship. The propeller device further comprises an energy-saving assembly, and the energy-saving assembly is used for being connected to the stern of the ship and is arranged close to the propeller body in the length direction of the ship. The energy-saving assembly comprises a plurality of blades, the blades are arranged on the stern of the ship in a surrounding mode, the roots of the blades are fixedly arranged on the surface of the stern, the blades extend outwards on the surface of the stern, and the distances between the tail ends of the blades and the end of the stern of the ship are at least different in the horizontal direction. The multiple blades are arranged in the length direction of the ship in a staggered mode, so that water flow in front of the propeller body is deflected, the water flow direction beneficial to the propeller body is generated, the propeller body obtains larger thrust under the same energy consumption, the propelling efficiency is improved, and energy consumption and emission of ship operation are reduced.
本发明公开了一种螺旋桨装置及船舶,涉及船舶制造技术领域。螺旋桨装置包括有螺旋桨本体,螺旋桨本体用于安装在船舶的船尾端部。螺旋桨装置还包括有节能组件,节能组件用于连接在船舶的船尾上,并在船舶的长度方向上临近螺旋桨本体设置。节能组件包括有多个叶片,多个叶片环绕设置在船舶的船尾上,叶片的根部固定设置在船尾的表面上,叶片在船尾的表面上向外延伸,多个叶片的尾端与船舶的船尾端部至少在水平方向的距离不同,以使多个叶片在船舶的长度方向上错位设置,从而对螺旋桨本体前方的水流进行偏转,产生有利于螺旋桨本体的水流流向,进而在相同的能耗下使得螺旋桨本体获得更大的推力,提升推进效率,减少了船舶运行的能耗和排放。
