Miniature spherical underwater vehicle based on water jet propulsion

Abstract

The invention provides a tiny spherical underwater submergence device based on water jet propulsion, which includes a shell and a driving and adjusting device arranged in the shell; the shell is a spherical sealed shell; the components of the driving and adjusting device include a seal cabin the two ends of which are arranged in the spherical sealed shell by a fixing pole support; two water spray motors are arranged in the seal cabin; water inlet tubes and water outlet tubes of the water spray motors penetrate the seal cabin and the spherical seal shell; besides, the diameters of the water inlet tubes of the water spray motors are smaller than the diameters of the water outlet tubes; the two symmetrical side surfaces of the seal cabin are provided with circuit boards; the other tow symmetrical side surfaces of the seal cabin are provided with battery tanks; the fixing pole supports at each end of the seal cabin are provided with a motor bracket; a motor cabin is arranged on the motor bracket; a fly wheel motor is arranged in the motor cabin; a fly wheel is arranged on the shaft of the fly wheel motor. The tiny spherical underwater submergence device based on the water jet propulsion has the advantages of higher flexibility, being capable of reducing the working noise to the utmost extent, simple material, small volume and low cost.

Description

(1) Technical field [0001] The invention relates to an underwater submersible. Specifically, it is a tiny underwater submersible whose main features are shape and driving mode. (2) Background technology [0002] Since the development of science, people have invested a lot of energy in the exploration of land and space, and have made great progress, but the understanding and research of the ocean, which is closely related to us, is relatively weak. [0003] In the vast ocean space, there are rich marine biological resources, marine mineral resources and marine energy, which we can rationally develop and utilize; at the same time, the earth's ecological environment is deteriorating day by day, and we must better protect the ocean, which covers a huge area of ​​the earth The environment is free from pollution, and they are efficiently used for the benefit of mankind. [0004] People's needs and desires for the exploration of rich marine resources and the protection of the mar...

Problems solved by technology

From the perspective of the propulsion method of the submersible, almost all underwater submersibles now use propeller propulsion as the main power. In a patent document entitled "A Drainage Propulsion Device for Underwater Robots" applied by Beijing Institute of Technology , involves the water jet propulsion method, but its drainage propulsion device uses a method similar to piston drainage, so its propulsion efficiency is low
