Abstract

The invention discloses a water spraying propelling system. The water spraying propelling system comprises a motor, a coupler, a pump, a reversing valve, a main pipeline, a safety valve and spraying port devices, wherein the motor is connected with the pump through the coupler, the reversing valve is installed on the main pipeline and respectively connected with a water inlet and a water outlet of the pump, the safety valve and the n spraying port devices are installed on the main pipeline, each spraying port device is composed of an electromagnetic valve, a spraying cavity and m spraying nozzles, the main pipeline is a closed loop, the number n of the spraying port devices is two or more, and the number m of the spraying nozzles is one or more. According to the main body structure of the water spraying propelling system, one main pipeline is connected with the pump and the n spraying port devices, plane propelling and rotation or six-freedom-degree motion control over a three-dimensional space are achieved, the structure is quite simple, the water spraying propelling system can be arranged inside or outside an underwater vehicle easily, and the hydrodynamic performance of the underwater vehicle is basically not affected. The water spraying propelling system adopts a bidirectional overflowing valve as the safety valve, achieves pressure relief of the inside of the main pipeline, and is favorable for improving the control accuracy of the underwater vehicle.

Description

technical field [0001] The invention relates to a water jet propulsion technology, in particular to a water jet propulsion system and its operation method. Background technique [0002] Waterjet propulsion technology is superior to traditional propeller propulsion methods in terms of acceleration, shallow draft navigation, high speed, maneuverability, low noise and reliability, so it has been widely used in the propulsion system applications of surface ships, ships and underwater vehicles. Rapid development. Especially in the application of underwater vehicles, the water-jet propulsion system can greatly improve the stealth of the vehicle, the flexibility of movement, and overcome the entanglement problem of propeller propulsion when navigating in shallow water. However, the traditional water-jet propulsion system has problems such as large volume, complex transmission mechanism, and poor scalability, which brings difficulties to the layout of the propulsion system and is n...
