Abstract

The invention provides a bionic fishtail underwater propeller, which relates to the technical field of underwater robots, and includes: a swing mechanism, which includes an elastic sheet and a rigid tail fin fixed at the tail end of the elastic sheet; a driving mechanism, which includes a steering gear; a transmission mechanism , The transmission mechanism includes a reel and a connecting line, the two ends of the connecting line are respectively connected to the swinging sides of the elastic sheet, and the reel is fixedly connected to the connecting line; the shell, the shell includes a head shell and a tail elastic shell body. The bionic fishtail underwater propeller provided by the present invention drives the reel to rotate in both directions through the steering gear, and the reel drives the connecting wire to drive the elastic sheet to swing left and right, and the swing process is not limited by frequency and has no hysteresis. The fish body wave is curved and continuous, and the bionic effect in water is good. The bionic fish tail underwater propeller of the invention has the advantages of simple structure, simple control, good flexibility and high bionic degree.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to a bionic fish tail 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 of the traditional underwater robots are propelled by propellers, which have disadvantages such as poor maneuverability, high noise and low concealment. The bionic robotic 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] The existing bionic robotic fish is usually composed of multiple connec...
