Bionic mechanical jellyfish

Abstract

The invention provides a machine bionic jellyfish. It is composed of a power system, a transmission system, a water spray system and a fixed frame. The power system is composed of four electromagnet devices. The transmission system is composed of four baffles and two return springs. It consists of one water inlet pipe and four water outlet pipes. The fixing frame is composed of left and right fixing beams. The electromagnet device is arranged on the baffle plate. The baffle plate is fixed on the upper and lower parts of the leather bag. The two ends of the spring are respectively fixed with the upper and lower baffles; the water inlet pipe is arranged at the front end of the skin bag, the water outlet pipe of the upper skin bag is symmetrically arranged at the lower rear end of the skin bag, and the water outlet pipe of the lower skin bag is symmetrically arranged at the upper and rear end of the skin bag. The invention is truly noiseless and has the advantages of complete functions, simple structure, high work efficiency, low price, easy maintenance and the like.

Description

(1) Technical field [0001] The invention relates to the technical field of ship propulsion, in particular to underwater detection equipment. (2) Background technology [0002] Noise is one of the biggest sources that affect the concealment of enemy reconnaissance. The propeller propeller noise is the main source of sound for enemy underwater acoustic equipment to monitor. Although some improvement measures have been taken, the desired effect is still not achieved. The solution of the problem seems to consider looking for other ways of propulsion. Someone once designed a paddle type and a fishtail swing type propeller, but it was not practical because of its complex structure and low efficiency; also someone once designed some water jet propulsion devices It is used on submarines, but it still cannot fundamentally eliminate the noise, because its drive or transmission is still noisy. [0003] Motion flexibility is an important indicator for evaluating underwater reconnaissan...

AI Technical Summary

Problems solved by technology

[0005] The application number is 200510010225.6, and the invention patent titled "Squid-like mollusk large-diving deep-water bionic robot" uses memory alloy and return spring as the transmission device. Because the memory alloy technology is not perfect and the response speed is slow, its propulsion The speed is limited; and it has only one water outlet, the steering is inflexible, and the stability is poor; although the propulsion principle of the invention patent whose application number is 00111425.5 is called "noiseless submarine pressurized water jet propeller", the noise is reduced. But its gear transmission mechanism still can't fundamentally eliminate the noise

[0006] Therefore, there is currently no equipment on the market that can solve the problems that plague underwater reconnaissance equipment such as noise and flexibility.
