The invention discloses an efficient sailing propeller and a force application pushing method. The propeller comprises a hull; a first engine and a second engine are installed in the stern of the hull; a first propeller rod and a first torque amplifier are obliquely installed; a second propeller rod and a second torque amplifier are obliquely installed; and the included angle formed between the first propeller rod and the horizontal line of the hull and the included angle formed between the second propeller rod and the horizontal line of the hull are both theta. The method comprises the following steps that: the mounting and fixing modes of the first propeller rod and second propeller rod are changed, first propeller blades deviate from the horizontal line of the hull by 3 degrees; secondpropeller blades deviate from the horizontal line of the hull by 3 degrees; the first engine drives the first propeller rod and the first propeller blades to rotate; and the second engine drives the second propeller rod and the second propeller blades to rotate. Under the condition that engine power and extra power consumption are not increased, power pushing can be changed, so that sailing speedis effectively increased, and meanwhile, an energy-saving effect can be achieved.

    本发明公开了一种高效航行的螺旋桨及施力推动方法,包括船体,船体的船尾内部安装有第一发动机和第二发动机,第一螺旋桨杆与第一扭矩增大器倾斜安装,第二螺旋桨杆与第二扭矩增大器倾斜安装,第一螺旋桨杆与船体的水平线形成夹角以及第二螺旋桨杆与船体的水平线形成夹角均为θ;步骤如下:改变第一螺旋桨杆和第二螺旋桨杆的安装固定方式,将第一螺旋桨叶向船体的水平线偏离3°,第二螺旋桨叶向船体的水平线偏离3°;第一发动机驱动第一螺旋桨杆和第一螺旋桨叶转动,第二发动机驱动第二螺旋桨杆和第二螺旋桨叶转动。本发明在没有增加发动机功率以及额外的功率消耗情况下,改变动力推动而有效的提升航行速度,同时能够达到节能效果。
