The invention provides an energy-saving guide pipe which is installed on the upstream portion of a propeller on the tail portion of a ship body, the energy-saving guide pipe comprises a nearly-semi-ring-shaped pipe assembly, the pipe assembly comprises a main body part and an extension part, the main body part is located in the middle of the pipe assembly in the circumferential direction, and the extension part is located in the middle of the pipe assembly in the circumferential direction. The two ends of the main body part in the circumferential direction extend outwards to form extension parts. According to the energy-saving guide pipe, the main body part and the extension parts in the pipe assembly are integrally arranged, so that the structure of the pipe assembly is relatively complete, the extension parts are formed by extending the two ends of the main body part in the circumferential direction, and the pipe assembly is installed in an offset mode, so that the wake flow of a stern can be improved, the power received by a propeller is reduced, and the energy-saving effect is finally achieved; wherein the pipe assembly replaces the rectification effect of part of the guide vanes, so that the number of the guide vanes is reduced, and the manufacturing cost and the maintenance and repair difficulty of the energy-saving guide pipe are reduced.

    本发明提供了一种节能导管,所述节能导管安装于船体尾部螺旋桨的上游,所述节能导管包括:呈近半环状的管组件,所述管组件包括主体部和延长部,所述主体部位于所述管组件周向上的中间位置,所述主体部周向上的两端向外延伸形成延长部。该节能导管,通过将管组件中的主体部和延长部一体设置,使管组件结构相对完整,通过延长主体部周向上的两端形成延长部,并对管组件偏置安装,可以改善船尾的伴流,降低螺旋桨收到功率,最终达到节能效果,其中管组件替代部分导叶的整流效果,进而减少导叶的数量,从而降低节能导管的制造成本以及维护和修理的难度。
