Underwater flapping propelling device

Abstract

The invention belongs to the technical field of robots, and aims to provide an underwater flapping propelling device having the advantages of being simple in structural design, small in size, light inweight, high in reliability and convenient to control. According to the technical scheme, the underwater flapping propelling device comprises a battery, and is characterized in that the underwater flapping propelling device includes an upper shell cover, a lower shell cover, a permanent magnet, an electromagnet, a control system, and a plurality of springs, wherein the tails of the upper shell cover and the lower shell cover are hinged to each other, and the outer surfaces are streamlined; the permanent magnet is fixed to the inner wall of the upper shell cover; the electromagnet is fixed tothe inner wall of the lower shell cover; the control system is fixed to the inner wall of the lower shell cover and electrically connected with the electromagnet to control on-off of the electromagnet; the springs are mutually parallel, and the two ends of each spring are fixed to the inner walls of the upper shell cover and the lower shell cover respectively; and the electromagnet corresponds tothe permanent magnet in position, so that when the upper shell cover and the lower shell cover are closed, the center lines of the electromagnet and the permanent magnet are just superposed.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to an underwater flapping propulsion device. Background technique [0002] At present, the main driving method used by underwater robots is the propeller type, which has large design size and power consumption. When driving underwater, it has poor adaptability to complex underwater environments, low reliability, and low driving efficiency. It will cause certain damage to the underwater ecological environment such as the ocean, so it is necessary to explore a new driving method for underwater robots. [0003] After tens of thousands of years of natural selection, the creatures in the ocean have each evolved their own unique way of swimming in the ocean. Marine organisms such as deep-sea shellfish rely on their light weight, small size and streamlined shells, fast-contracting obturator muscles and hinge elastic properties of the internal and external ligaments, and use the highly deve...
