Bladeless underwater propulsion system

Abstract

The invention provides a bladeless underwater propulsion system. The bladeless underwater propulsion system comprises a main base body, a vertical propeller set and a horizontal propeller set. The main base body comprises a shell, a variable-frequency direct-current permanent magnet motor, a cable connector, supercharging equipment, a water inlet pipeline, a water outlet pipeline and the like. Thevertical propeller set is used for providing power for the bladeless underwater propulsion system to float upwards, and the horizontal propeller set is used for providing power for the bladeless underwater propulsion system to advance, retreat and turn. An electromagnetic valve is arranged on the water outlet pipeline and used for adjusting the size and direction of water flow of outlet pipelinesof all the branches, then the thrust of all the propellers is changed, and therefore the movement functions of floating, diving, advancing, retreating, turning and the like of the bladeless underwater propulsion system are achieved. The bladeless underwater propulsion system can adapt to underwater severe environments, and has the advantages of high compatibility, low noise, high safety coefficient, compact structure, small size, light weight and the like.

Description

technical field [0001] The invention relates to the field of underwater propulsion, and is suitable for use as a power device for unmanned underwater vehicles, in particular to a bladeless submarine propulsion system. Background technique [0002] With the development of my country's science and technology, my country's underwater unmanned submersibles and related technologies are getting better and better, and the functions and application places of the underwater unmanned submersibles made It can not only detect underwater operations in highly dangerous waters, but also replace manual detection of underwater operations in shallow water areas. Some of the more common fields such as marine energy mining, underwater detection of dam gate valves, cleaning of sewer pipes, dredging of water areas, Water environment testing, etc. Therefore, underwater unmanned submersibles are of great significance to our production and life. In the process of research and development of underwate...

AI Technical Summary

Problems solved by technology

However, during the actual use of the propeller propeller, the blades are often entangled by aquatic plants and other debris, resulting in malfunctions and loud noises, making it impossible to sneak in turbid waters (containing solid particles such as sand and aquatic plants and other debris); and A vehicle needs to be equipped with multiple sets to maintain the adjustment of the direction of travel. It needs multiple sets of motors or power devices to drive, which is bulky and cumbersome to control.

For some underwater miniature submersibles, energy-saving pump-jet propellers are used to provide power, and four airfoils are used for multi-degree-of-freedom control. Although it has the advantages of simple structure, energy saving and environmental protection, there are also obvious shortcomings and problems: The airfoil wall can only control the direction and cannot provide power; the blades are easily damaged and need to be replaced regularly

Although the magnetic fluid thruster has the advantages of flexible maneuverability, good maneuverability, low vibration and noise, and convenient layout, it has high costs, incomplete technical conditions, and cannot work in freshwater environments.
