Low-energy-consumption magnetomotive propelling mechanism of bionic robot fish

Abstract

The invention discloses a low-energy-consumption magnetomotive propelling mechanism of a bionic robot fish. The low-energy-consumption magnetomotive propelling mechanism comprises a body, i.e. a magnetomotive tail fin, wherein the magnetomotive tail fin comprises a U-shaped connecting frame, a magnetic induction coil, a strong-magnetic swinger and a crescent flexible tail fin; the magnetic induction coil is formed by winding silk-covered wires on a PVC (Poly Vinyl Chloride) bobbin; the strong-magnetic swinger is arranged on the central position of a rotary shaft in a pull-in manner by adopting two round strong-magnetic permanent magnets; the two ends of the rotary shaft are arranged on two small bearings; the tail end of the rotary shaft locks inner races of the small bearings by a clamping pin; the U-shaped connecting frame connects a fish body and the crescent flexible tail fin which consists of a tail handle and a fin surface. The low-energy-consumption magnetomotive propelling mechanism disclosed by the invention has the advantages that the structure is simple, the volume is small, and the processing is convenient; the insulating and waterproof performances are good; any waterproof protection is not needed, so that the complexity of the mechanism is greatly reduced; the electromagnetic induction principle is adopted to realize no-noise driving; the propelling efficiency is high and the working voltage of the magnetomotive propelling mechanism is wider.

Description

technical field [0001] The invention relates to a magnetic power propulsion mechanism, in particular to a magnetic power propulsion mechanism of a bionic robotic fish with low energy consumption. Background technique [0002] With the continuous development of marine resources, autonomous underwater robots have gradually become an important platform for human ocean exploration and research. However, most of the traditional autonomous underwater robots use conventional propellers and impellers. The propulsion efficiency of these propellers generally hovers around 40%-60%. In addition, the structure is huge, the noise is large, and the environment is greatly disturbed. Shortcomings such as poor flexibility and poor concealment restrict the application of conventional underwater thrusters. At present, more and more autonomous underwater robots have given up the traditional propeller propulsion method, and use the swimming method that imitates the high-performance wave pro...
