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.

Abstract

The bionic mechanical jellyfish consists of a power system comprising four electromagnet devices, a driving system comprising four baffles and two return springs, a water jetting system comprising two leather bags, two water inlet pipes and four water outlet pipes, and a fixing rack comprising a right and a left fixing beam. The present invention has no noise, complete functions, simple structure, high work efficiency, low cost and other advantages.

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; some people also designed some water jet propulsion devices It is used on submarines, but the foot still cannot fundamentally eliminate the noise, because its drive or transmission still has noise. [0003] Motion flexibility is an important indicator for evaluating underwater reconn...
