The invention relates to an environment-friendly propeller. The scull blade assembly comprises at least one pair of scull blades, a limiting device and a front edge shaft, and the scull blades are rotationally limited through the limiting device, so that when the scull blade front edge shaft swings in water, the scull blades scratch a water body through an inclined plane and generate backward thrust; the scull blade transmission mechanism drives at least one pair of scull blades to continuously and symmetrically swing underwater; the frame is installed on the stern, and the scull blade transmission mechanism is installed on the frame; and the steering engine comprises a rudder sheet for controlling the course and a steering driving wheel for driving the frame and the rudder sheet to rotate. Compared with the prior art, the scull blades of the propeller scrape a large water body area every time, especially the scull blades scrape a relatively static water body, so that the water body counter-acting force obtained by the propeller is larger, and the propelling efficiency is improved.
本发明涉及一种环保推进器。本发明包括橹叶组件,包括至少一对橹叶、限位装置和前沿轴,所述橹叶通过限位装置进行转动限位,使橹叶前沿轴在水中摆动时橹叶以斜面划过水体并产生向后推力;橹叶传动机构,驱动至少一对橹叶作连续的水下对称摆动;安装于船尾的框架,所述橹叶传动机构安装于框架;舵机,包括控制航向的舵片以及驱动框架及舵片转动的转向驱动轮。本发明推进器的橹叶每次划过大得多的水体面积,尤其所划过的都是相对静止的水体,因而推进器得到的水体反作用力更大,提高了推进效率。
