The invention relates to the field of ship transportation energy conservation, in particular to a container ship propeller double-sleeve energy-saving device. The technical problems that the form of bubbles generated by an air lubricating system cannot be adjusted, and a front energy-saving device is different in energy-saving effect and even generates negative effects at different navigational speeds are solved. The invention provides a container ship propeller double-sleeve energy-saving device. The container ship propeller double-sleeve energy-saving device comprises an efficient propeller and the like. The efficient propeller is installed on the tail portion of the container ship in a sealed and rotating mode, the stern sealing installation component is arranged on the tail portion of the container ship, the front energy-saving component is arranged on the stern sealing installation component, and the bubble lubricating component is arranged on the front portion of the container ship. The front energy-saving component is matched with the stern sealing installation component, the pre-rotational flow state and the inflow effect generated after water flow passes through the front energy-saving component are changed, the part, making contact with the container ship, of the water surface is isolated through the bubble lubricating component, and the frictional resistance of the water surface to the ship bottom is reduced.
本发明涉及船舶运输节能领域,尤其涉及一种集装箱船螺旋桨双套节能装置。本发明的技术问题为:空气润滑系统产生的气泡形态不可调,前置节能装置在不同航速下其节能效果不一甚至产生负面影响。本发明提供了一种集装箱船螺旋桨双套节能装置,包括有高效螺旋桨等;高效螺旋桨密封转动安装在集装箱船尾部,集装箱船尾部设置有船艉密封安装部件,船艉密封安装部件上设置有前置节能部件,集装箱船前部设置有气泡润滑部件。本发明通过前置节能部件配合船艉密封安装部件,对水流通过前置节能部件后产生的预旋流状态和进流效果进行改变,通过气泡润滑部件实现对与集装箱船与接触的水面的部分隔绝,减少水面对船底的摩擦阻力。
