Bionic Tail Fins for Powering Measuring Equipment on Water

Abstract

The invention provides a bionic tail fin capable of being used for overwater measuring equipment power. The bionic tail fin is mainly characterized in that transmission shafts in transmission connection with two sliding blocks connected to two guide rails are arranged in a tail fin shell, sliding block movement starting and stopping limiting pieces are arranged at the position, at the two ends of each sliding block, of each guide rail, photocoupling switch devices are arranged at the positions of the sliding block movement starting and stopping limiting pieces of each sliding block, the two ends of each sliding block are provided with light shading boards, one end of each guide rail is provided with an electromagnet, and the electromagnets are connected with an electric controller. The bionic tail fin has the beneficial effects of being environment-friendly, free of pollution, good in silencing effect, simple in structure, low in cost and long in service life, and the propelling efficiency and the energy-saving effect can be effectively improved. The bionic tail fin can be used for a system such as a small hydrographic survey vessel with the relatively high self-restraint time requirement, can also be used as a propelling system for a pure electric propelling ship and further can be used for certain special occasions, such as underwater acoustical signal collection, with the special requirements for the noise of the propelling system.

Description

technical field [0001] The invention relates to a power mechanism for driving water measurement equipment, in particular to a bionic tail fin which can be used for the power of water measurement equipment, and is suitable for driving the movement of water and underwater measurement equipment. Background technique [0002] Usually, there are many types of power mechanisms that drive the motion of objects in water and water, mainly propellers, mechanisms based on bionics principles, such as artificial fins, superconducting magnetic fluid thrusters, etc. [0003] Although the propeller as a ship driving mechanism has been widely used in ship driving, it has obvious shortcomings such as low transmission efficiency, high energy consumption, and high noise. [0004] In recent years, many people have used the principle of bionics to make a simple artificial tail fin based on the fish tail, which is used as the driving force to drive the ship forward. It has high efficiency, low noi...

Problems solved by technology

At present, the driving method of this simple artificial caudal fin is divided into the following two methods: one is to use stepper motor or servo motor to drive, the mechanism of this driving method is complicated and the cost is higher; the other is to use crank-link mechanism mechanical Device drive, this drive method is to convert circular motion into reciprocating motion, because it is mainly composed of mechanical components, so the friction is large, the wear is also large, and the efficiency is low

[0005] In addition, a superconducting magnetic fluid thruster is also used. Although the superconducting electromagnetic fluid thruster has the characteristics of quietness, no noise, and easy operation, the cost of the superconducting electromagnetic fluid thruster is high, and the speed is slow. A large generator is needed as power, which will not only increase the weight of the ship or submarine, but also the speed of the power system of the large generator as the driving force is higher than that of the superconducting magnetic fluid propeller, which cannot directly drive the superconducting magnetic fluid propeller, and needs to be increased Equipment investment will make the cost higher
