Problems solved by technology

[0003] The existing propulsion system is mainly based on the device with blades, which is not only noisy, but also easily entangled by weeds. At the same time, a vehicle needs to be equipped with multiple propellers to maintain the adjustment of the direction of travel. Therefore, multiple sets of motors or power The device is driven, resulting in large volume and cumbersome control
[0004] For some water tank miniature submersibles, 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
At the same time, the existing magnetic fluid thrusters have high cost, incomplete technical conditions, and cannot work in freshwater environments

Abstract

The invention relates to a blade-free propelling system. The blade-free propelling system comprises a main body, a universal head and a water spraying assembly, the body is used for generating high-pressure water flow; the universal head is used for providing steering for the water spraying assembly; the water spraying assembly comprises a nozzle, the nozzle comprises an internal channel used for receiving high-pressure water flow from the main body and a gap-shaped water outlet used for spraying the water flow, the nozzle is provided with a plurality of similar closed loops, and the inner wall face of the nozzle is composed of a Coanda surface, a wing-shaped diffusion surface and a guide surface. The blade-free propelling system has the advantages of blade-free propelling, multi-degree-of-freedom automatic control, low noise, high safety coefficient, small size, high compatibility and the like.

Description

technical field [0001] The invention relates to the technical field of underwater propulsion, in particular to a bladeless propulsion system. Background technique [0002] As human beings pay more and more attention to ocean rights and interests, ocean exploration and ocean development have become a new direction for the development of science and technology in the future. Pay attention to. Having an underwater robot with good performance is an important tool for human beings to explore the ocean in depth, so it has received more and more attention. Among them, in the research and development process of underwater robots, its internal propulsion system is a very important link. [0003] The existing propulsion system is mainly based on the device with blades, which is not only noisy, but also easily entangled by weeds. At the same time, a vehicle needs to be equipped with multiple propellers to maintain the adjustment of the direction of travel. Therefore, multiple sets of...
