Technical Field

The invention belongs to the field of underwater propulsion systems, and relates to a device for spraying sucked water out for doing work by utilizing compressed gas.

Background

With the increasing underwater exploration activities of ocean rivers and the like, the development of various underwater navigation equipment is promoted. At present, the underwater equipment mainly adopts a propeller propulsion mode, a bionic propulsion mode and a water jet propulsion mode. As for the driving energy, the underwater equipment carrying the battery is mostly adopted to provide the energy.

The traditional water spraying device takes a battery as a unique energy source, and the battery needs to be charged after being used, so that the charging time is long, and the traditional water spraying device is not beneficial to secondary or repeated submergence. The compressed gas as energy has high compression speed and can finish secondary submergence in short time. Meanwhile, the propeller is utilized to automatically absorb water, so that the utilization rate of compressed gas can be effectively improved.

Disclosure of Invention

In order to solve the problems, the invention provides a novel compressed gas-based water-spraying type propeller, which aims to enable an underwater propeller to efficiently utilize the energy of compressed gas, has a simple structure, automatically completes the processes of air inlet, water spraying, air exhaust and the like, and reduces the switching frequency of an air source.

In order to achieve the above object, the present invention provides a compressed gas based water jet propeller. The propeller cabin body consists of a shell and a nozzle, water is filled in the cabin body, high-pressure gas enters the cabin body from a pressurization port, and the water in the cabin body is pressed out from the nozzle. The water pressed out from the spout has a certain velocity so that the propeller obtains a reverse thrust with respect to the direction of the spout.

The working process of the device is as follows.

The work cycle is completed from filling water, inflating to filling water in the shell: after high-pressure gas is filled into the shell through the pressurizing opening, the high-pressure gas extrudes water, so that the one-way baffle of the nozzle is opened, and the water is sprayed out from the nozzle under the pressure action of the high-pressure gas, so that the propeller obtains power. The water in the water cavity is continuously pressed out by the filling of the high-pressure gas, the water surface continuously descends, and when the liquid surface descends to a specified position, the pressurization port is closed, and the exhaust port and the water inlet are opened. The medium water outside flows into the shell, and the air outlet and the water inlet are closed after the liquid level reaches the designated height, so that one working cycle is completed.

Further, the underwater power nozzle can be designed into a variable-opening vector nozzle, so that the variable jet thrust and the variable propulsion direction can be realized by controlling the nozzle.

Furthermore, the number of the propelling cabins in the scheme is one or more, and a plurality of propelling cabins are integrated into a whole according to the requirement to form a cluster jet propelling device, so that the single small-pulse jet propelling, the multiple large-pulse jet propelling and the alternate continuous jet propelling can be realized.

Furthermore, the pressurizing port, the exhaust port and the water inlet can be linked in a mechanical mode such as an impeller and a gear, and can be opened and closed in a mode of an electromagnetic valve.

Furthermore, the range of the propeller can be increased by increasing the volume of the air source storage device or increasing the pressure of stored air.

(1) The invention takes high-pressure gas as a power source and provides advancing power by spraying water, has simple structure and large thrust and can be repeatedly used; and the high-pressure gas is easy to obtain, the pressurization is fast, and the secondary deployment launching is convenient.

(2) The invention utilizes the cavity formed in the shell to store the aqueous medium, and the high-pressure gas inlet device is closed after the water in the cavity is substantially drained. Thereby reducing the switching times of the air inlet device and being beneficial to improving the reliability of the product.
