The invention belongs to the technical field of bionic underwater propellers, and particularly relates to a two-joint bionic fishtail device capable of swinging at a high speed. The fishtail comprisesa fishtail front part, a fishtail middle part and a fishtail tail fin, a driving device mounting frame, a driving shaft, a first crankshaft and a second crankshaft are arranged in the fishtail frontpart; a first joint driven shaft is arranged at the front end of the fishtail middle part; and a second joint driven shaft is arranged at the front end of the fishtail tail fin. During operation, thedriving shaft is driven by a motor to rotate so as to drive the first crankshaft and the second crankshaft to rotate through gears, the first crankshaft and the second crankshaft drive the first jointdriven shaft and the second joint driven shaft to rotate through the belts arranged on connecting rod journals in a sleeving mode correspondingly, and the bionic fishtail swinging is achieved. The high-speed swinging of the double-joint bionic fishtail can be achieved only through the single motor, and the rapid maneuvering of the robotic fish is achieved.
本发明属于仿生水下推进器技术领域,具体涉及一种高速摆动的两关节仿生鱼尾装置。本发明包括鱼尾前部、鱼尾中部和鱼尾尾鳍;鱼尾前部中设有驱动装置安装架、主动轴、第一曲轴和第二曲轴;鱼尾中部的前端设有第一关节从动轴;鱼尾尾鳍的前端设有第二关节从动轴。本发明运行时,主动轴在电机的驱动下转动从而通过齿轮带动第一曲轴和第二曲轴转动,第一曲轴和第二曲轴通过套在连杆轴颈上的皮带分别带动第一关节从动轴和第二关节从动轴转动,实现仿生鱼尾摆动。本发明仅依靠单个电机就可实现双关节仿生鱼尾的高速摆动,实现了机器鱼的快速机动。
