The invention discloses a marine energy-saving stator which comprises an X shaft, a propeller is arranged on the outer side of the X shaft, a paddle disc face is arranged on one side of the propeller, a movable block is arranged on one side of the paddle disc face, a movable hook is arranged on one side of the movable block, a first blade is arranged on one side of the movable hook, and a second blade is arranged on one side of the first blade. And a third blade is arranged on one side of the second blade. According to the marine energy-saving stator, the paddle efficiency can be improved within the full navigational speed range, the purposes of energy conservation and emission reduction are achieved, meanwhile, the vibration noise problem is solved, and through CFD simulation and ship model pool tests, the energy-saving effect is improved by 20%-80% compared with a traditional stator. When the three-blade scheme is used, the construction cost can be additionally saved, in order to improve the propelling efficiency and consider the line type of the tail of the ship body, the blades are arranged in front of the propeller, the blades are reasonably arranged in the rotating range of the whole propeller, and the blades are arranged in the first quadrant, the fourth quadrant and the third quadrant in front of the propeller disc face respectively.
本发明公开了一种船用节能定子,包括X轴,所述X轴外侧设置有螺旋桨,且螺旋桨一侧设置有浆盘面,所述浆盘面一侧设置有活动块,且活动块一侧设置有活动钩,所述活动钩一侧设置有第一叶片,且第一叶片一侧设置有第二叶片,所述第二叶片一侧设置有第三叶片。该船用节能定子,能够在全航速范围内提高船桨效率,达到节能减排的目的,同时有利于改善振动噪音问题,本方案经过CFD仿真及船模水池试验,节能效果比传统定子提高20%~80%。当使用三片方案时,可以额外节省建造成本,为了提高推进效率,考虑船体尾部线型,通过在螺旋桨前布置叶片,叶片在整个螺旋桨旋转范围内合理布置,在桨盘面前方第一象限,第四象限,第三象限分别布置叶片。
