A bionic robot fish

Abstract

The invention belongs to the field of underwater detection, and specifically relates to a bionic robotic fish. A bionic robot fish, comprising a shell; an upper fin fixed on the top of the shell; a lower fin fixed on the bottom of the shell; a fish tail fixed on the tail of the shell; a copper shell set inside the shell; The side wall at one end of the shell is provided with an external thread; the inner side of the sealing cover is provided with an internal thread that matches the external thread of the copper shell, and is connected with the copper shell through threads; three magnetic control structures are respectively arranged on the upper fish fin, The lower fin and the inside of the fish tail are used to drive the movement of the upper fin, lower fin and fish tail, and then drive the movement of the bionic robot fish; the three electronic control structures are fixed in the copper shell, and their installation positions are respectively in line with the The positions of the upper fin, the lower fin and the fish tail match to drive the magnetic control structure; the radio remote control communicates with the electronic control structure and is used to remotely control the direction and speed of the bionic robotic fish underwater.

Description

technical field [0001] The invention belongs to the field of underwater detection, and in particular relates to a bionic robot fish. Background technique [0002] Water resources are the foundation of human survival. In order to make remote water quality detection or underwater condition detection more convenient, people have invented a series of machines that work underwater. However, the current underwater exploration machines are all directly powered by electric energy, and the pulse current passes through the stepper motor to form a certain angular velocity or linear velocity to drive the rotation of the propeller in the water, and then push the machine to move underwater. Due to the pressure and fluidity of water, this kind of energy supply system is faced with the risk of seal failure caused by friction between the propeller, gear or other rotating parts and the motor structure, resulting in water ingress, electric leakage, engine damage, etc. In order to avoid such R...

AI Technical Summary

Problems solved by technology

Due to the pressure and fluidity of water, this kind of energy supply system is faced with the risk of seal failure caused by friction between the propeller, gear or other rotating parts and the motor structure, resulting in water ingress, electric leakage, engine damage, etc. In order to avoid such Risk, the current underwater machines all use mechanical dynamic seals, but dynamic seals have disadvantages such as complex structure, high manufacturing cost, and difficult processing, so it is difficult to popularize the technology to the field of ordinary underwater toys
