The invention provides a novel bionic propeller which comprises propeller blades, the propeller blades are installed on a propeller hub, bionic fins are installed on the blade edges of the propeller blades, connecting rods are arranged in the bionic fins, and small generators are installed at the tail ends of the connecting rods. The swing of the bionic fins made of the polyurethane plate covering materials and arranged on the edges of the propeller blades is utilized to drive the connecting rods arranged in the bionic fins made of the polyurethane plate covering materials to swing, the swing of the connecting rods is transmitted to the small generators installed in the propeller blades, the small generators start to work, and the existence of the bionic fins is beneficial to ship propulsion to a certain extent. Finally, the purposes of recovering rotation energy and wake flow energy when the propeller works and ocean current energy when the ship stops voyage and improving the propulsion efficiency of the ship are achieved.
本发明提供一种新型仿生螺旋桨,包括螺旋桨桨叶,所述螺旋桨桨叶安装在螺旋桨桨毂上,螺旋桨桨叶的叶边安装有仿生鳍,仿生鳍内部设置有连杆,连杆末端安装有小型发电机。本发明利用螺旋桨桨叶叶边布置的聚氨酯板覆材的仿生鳍的摆动,带动聚氨酯板覆材的仿生鳍内部设置的连杆摆动,连杆的摆动传递到安装在螺旋桨桨叶内部的小型发电机处,小型发电机开始工作,并且仿生鳍的存在也会在一定程度上有利于船舶推进。最终实现螺旋桨工作时的转动能量、尾流能量以及船舶停航时的洋流的能量回收,提高船舶推进效率的目的。
