BACKGROUND ART

The underwater world contains a lot of energy and rich resources, which play an important role in human understanding of the world and social development. As an important means of exploring the underwater world, an intelligent underwater vehicle is an underwater vehicle that can be carried by an aircraft, a surface ship, a submarine, etc. The intelligent underwater vehicle has main functions of searching, rescuing and autonomous ocean exploration, and can also carry a detector, an underwater prefabricated weapon, a mine, etc., can independently complete a series of tasks. Autonomous underwater vehicles are currently widely valued by countries around the world, and are effective tools for human beings in the modern society to know the ocean and develop and utilize the ocean.

At present, most intelligent underwater vehicles use lead-acid batteries, alkaline batteries or lithium batteries for energy supply.

Referring to FIG. 1 to FIG. 4, as one aspect of the present disclosure:

A wingless hydraulic extrusion spiral rotation and forward movement type intelligent unmanned underwater vehicle includes a cabin body 100 and a control module 4. The cabin body 100 includes a power fuel storage cabin 1 and a power reaction cabin 2. A power reaction cabin water supply device 3 is fixedly arranged on the cabin body 100.

The power reaction cabin 2 and the power fuel storage cabin 1 are separated by a partition plate. The power reaction cabin 2 is located on the left side of the power fuel storage cabin 1. Power fuel in the power fuel storage cabin 1 may enter the power reaction cabin 2. A tail part of the power reaction cabin is provided with a jet forward propeller 21.

The control module 4 is fixed on the power fuel storage cabin 1.

The power reaction cabin water supply device 3 is fixed on the upper part of the power reaction cabin 2.

At least two jet rotation propellers 5 are arranged on the cabin body 100. A center axis of an outlet of each jet rotation propeller 5 and a center axis of the cabin body form an included angle of 10-40 degrees; the jet rotation propeller 5 includes a main propelling pipe 51, an auxiliary propelling pipe 52, and a jet magnification ring 53; and the jet magnification ring 53 includes an outer ring 531 and an inner ring 532, referring to FIG. 5 and FIG. 6.

In the present disclosure, the center axis of an outlet of each jet rotation propeller 5 and the center axis of the cabin body form an included angle of 10-40 degrees, so that when jetted water applies a counter-acting force to the cabin body, the cabin body rotates step by step, and the vehicle can keep stable rotation and forward movement under the impact of seawater.

In some embodiments, referring to FIG. 5 and FIG. 6, a tail end of the main propelling pipe 51 is provided with six auxiliary propelling pipes 52 uniformly arranged on a circumference in an outwards diffusion manner, and an outlet 521 of each auxiliary propelling pipe 52 is led into the jet magnification ring 53.

Referring to FIG. 7, the outlet 521 of each auxiliary propelling pipe 52 is bent, so that the direction of the outlet 521 deviates from the center axis of the auxiliary propelling pipe 52 by 40-90 degrees. When the water flow jetted from this bent outlet applies the counter-reacting force to the cabin body, it is more conductive to gradual rotation of the cabin body, so that the vehicle can keep stable rotation and forward movement under the impact of the seawater.

In some embodiments, referring to FIG. 1 to FIG. 3, the power fuel storage cabin 1 includes a power fuel extrusion hood 11 and a power fuel outlet valve 12; a tail end of the power fuel extrusion hood 11 is lined within the power fuel storage cabin 1 and is freely slidable back and forth and sealable; the power fuel outlet valve 12 is located at the tail part of the power fuel storage cabin 1, passes through the partition plate between the power reaction cabin 2 and the power fuel storage cabin 1, and extends into the power reaction cabin 2; and power fuel 13 is arranged in the power fuel storage cabin 1. In the forward movement process of the vehicle, the power fuel extrusion hood 11 backwards compresses the power fuel 13 in the power fuel storage cabin 1 under an extrusion force of water in the front, so that the power fuel 13 can enter the power reaction cabin subassembly at the back through the power fuel outlet valve 12.

In some preferable embodiments, the power fuel outlet valve 12 is a check valve.

In some embodiments, referring to FIG. 1, the power fuel 13 is a substance that can react with water and produce gas and/or energy.

In some preferable embodiments, the power fuel is gelatinous liquid formed by sodium metal particles or sodium metal powder and kerosene or other nonreactive oil substances. The power fuel in the power fuel storage cabin adopts the gelatinous liquid formed by sodium metal particles or sodium metal powder and kerosene or other nonreactive oil substances; the sodium metal particles or sodium metal powder is uniformly suspended in the above medium and are sprayed into the reaction cabin through the power fuel outlet valve at the rear part of the power fuel storage cabin to react with water to produce gas and/or energy that is used as movement energy of the underwater vehicle.

The power fuel in the power fuel storage cabin 1 may enter the power reaction cabin 2 in one way and is mixed with the water in the power reaction cabin for reaction. Gas is released, and pressure is generated, so that a gas-water mixed solution is jetted to the outside through the jet rotation propeller 5, so as to push the vehicle to rotatably forward. By means of adjusting the direction and jet pressure of the jet rotation propeller 5, acceleration, deceleration, floating and sinking of the vehicle can be adjusted.

In some embodiments, referring to FIG. 1, the power reaction cabin water supply device 3 includes a water supply pump 31, a filter 32, and a water inlet check valve 33; the water supply pump 31 is mounted in the power reaction cabin water supply device 3; the filter 32 is mounted at the lower part of the power reaction cabin water supply device 3; and the water inlet check valve 33 is used for connecting the power reaction cabin water supply device 3 with the power reaction cabin 2. Therefore, filtered water can enter the power reaction cabin 2 in one way.

In some embodiments, the control module 4 includes an environmental sensor, a depth sensor, a temperature sensor, a controller, a main control board, an energy management board, a radio station component, a positioning module, an attitude sensor module, an electronic compass module, and a lithium battery pack; and the environmental sensor, the depth sensor, the temperature sensor, the controller, the main control board, the energy management board, the radio station component, the positioning module, the attitude sensor module, the electronic compass module, and the lithium battery pack are all arranged in the control module subassembly.

The working principle of the wingless hydraulic extrusion spiral rotation and forward movement type intelligent unmanned underwater vehicle of the present disclosure is as follows:

Referring to FIG. 1 to FIG. 7, the unmanned underwater vehicle of the present disclosure has no initial power and can be loaded on a surface ship, a submarine, an airplane, and other systems. During use, the unmanned underwater vehicle is launched to a predetermined position. An instruction is received through the environmental sensor in the control module 4. The check valve 12 between the power fuel storage cabin 1 and the power reaction cabin 2 is opened. The power fuel, that is, the gelatinous liquid formed by the sodium metal particles or sodium metal powder and kerosene or other nonreactive oil substances, is arranged in the power fuel storage cabin 1. Since the power fuel extrusion hood 11 in the power fuel storage cabin 1 continuously impacts water, the power fuel inside the power fuel storage cabin is pressed by the pressure inside the power fuel storage cabin 1 into the power reaction cabin 2 through the check valve 12. The inside of the power reaction cabin 2 is communicated with the water inlet check valve 303 through the water supply pump 301 to cause water to enter the reaction cabin 2. The power fuel entering from the power fuel storage cabin 1 is mixed with the water for reaction. Gas is released, and a high pressure is generated. At this time, the jet forward propeller 21 and the jet rotation propeller 5 are turned on, so that the gas-water mixed solution is jetted to the outside through the jet forward propeller 21 and the jet rotation propeller 5 to push the underwater vehicle to move forwards and rotate. As the underwater vehicle spirally rotates and forwards moves, the power fuel extrusion hood 11 continues to impact water, and a pressure is continued to be generated inside the power fuel storage cabin 1 to continuously extrude the internal power fuel into the power reaction cabin 2. The power fuel continuously reacts with the water inside the power reaction cabin 2 to continuously produce gas and water mixtures which are jetted through the jet propeller 5. This circulating process enables the underwater vehicle to obtain power for continuously forwards moving without an external force. Turning off the jet forward propeller 21 and the jet rotation propeller 5 can decelerate the vehicle. The control module 4 adjusts a state of the underwater vehicle, speeds of forward movement, backward movement, up-and-down floating and spiral rotation, and an information transmission function by means of the environmental sensor, the depth sensor, the temperature sensor, the controller, the main control board, the energy management board, the radio station component, the Beidou/GPS (Global Positioning System) positioning module, the attitude sensor module, the electronic compass module, and the lithium battery pack.

The above-mentioned process is repeated, so that the present disclosure can autonomously provide power for navigation, which greatly saves the energy, thereby the unmanned underwater vehicle can undertake tasks such as maritime patrol and reconnaissance and maritime relay communication.

The present disclosure combines the traditional concept with the self-sufficient design mode, so that the underwater vehicle has two modes, that is, it can be controlled manually or can generate kinetic energy independently for running. The underwater navigation can be performed like an unmanned surface ship, such as maritime patrol and reconnaissance, maritime relay communication, marine environment survey, polluted water monitoring, and other tasks. The underwater vehicle has strong environmental adaptability, better maneuverability and higher safety.

Apparently, the above-mentioned embodiments of the present disclosure are merely examples for illustrating the present disclosure, and are not intended to limit the implementation modes of the present disclosure. Those of ordinary skill in the art can further make other changes or modifications in different forms on the basis of the above-mentioned descriptions. It is not possible to give an exhaustive list of all implementation modes here. All obvious changes or modifications derived from the technical solutions of the present disclosure still fall within the protection scope of the present disclosure.
