Abstract

The invention provides a bionic fishtail underwater propeller and relates to the technical field of underwater robots. The bionic fishtail underwater propeller comprises a swing mechanism, a driving mechanism, a transmission mechanism and a shell, wherein the swing mechanism comprises an elastic sheet and a rigid tail fin fixed at a tail end of the elastic sheet; the driving mechanism comprises a steering engine; the transmission mechanism comprises a winder and a connecting line, the two ends of the connecting line are fixedly connected with the two swinging sides of the elastic piece respectively, and the winder is fixedly connected with the connecting line; and the shell comprises a head shell body and a tail elastic shell body. According to the bionic fishtail underwater propeller, the steering engine drives the winder to rotate in two directions, the winder drives the connecting line to drive the elastic piece to swing left and right, the swinging process is not limited by frequency, the hysteresis effect does not exist, fish body waves are bent and continuous, the bionic effect in water is good, the bionic fishtail underwater propeller has advantages of being simple in structure, easy to control, good in flexibility and high in bionic degree.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to a bionic fishtail underwater propeller. Background technique [0002] Since the 21st century, with the development and utilization of marine resources, underwater robots have become a powerful tool for exploring and developing the ocean. Most traditional underwater robots are propelled by propellers, which have disadvantages such as poor maneuverability, loud noise and low concealment. The bionic robot fish has the advantages of high propulsion efficiency, low energy consumption, good maneuverability, low noise and high concealment, and has attracted great attention from researchers at home and abroad. Bionic robotic fish has a wide range of applications in many fields, such as the detection and development of marine resources, military reconnaissance and underwater archaeology. [0003] Existing bionic robotic fish are usually composed of multiple connecting rods in ...
