[0003] The underwater unmanned vehicle is a robot that can perform tasks autonomously underwater, which can usually complete underwater exploration, detection and even military attack and defense tasks. The underwater unmanned vehicle can assist us in exploring the seabed. The traditional underwater unmanned vehicle generally uses electric power or hydraulic power as a power source, but due to the complex environment in water, the power system of the underwater unmanned vehicle is required, and these two power modes have advantages and disadvantages, which cannot meet the demand of underwater task execution. Therefore, more and more hybrid underwater vehicles have appeared. The underwater unmanned vehicle is always working underwater, so using water flow energy to provide power for the vehicle and propelling the underwater unmanned vehicle forward is the mainstream trend of the underwater unmanned vehicle propulsion device.

[0007] By adopting the technical scheme, the device can be used in three situations, when the device just enters water, the storage battery provides power for the navigation equipment to support the operation of the navigation equipment, and the device is moved to the working area by the navigation equipment.

[0008] In the working area, the water flow enters the propeller and impacts the rotation plate, the rotation plate moves to drive the rotation shaft to rotate, and then the generator is started to generate electricity, the water flow energy is converted into electric energy, the electric energy generated by the generator is used to supply the navigation equipment, the water pump and the water sprayer, the voltage stabilizer ensures the stable output voltage, avoids the situation that the device components are burnt out due to the unstable output pressure caused by continuous power generation, the water flow entering the propeller moves the rotation plate and then flows out from the bottom of the propeller far from the vacuum chamber, enters the water outlet buffer groove, enters the water sprayer under the action of the water pump, enters the water suction pipe through the water suction hole, and is sprayed out through the water spraying hole, when the water sprayer sprays water, the reaction force of the water flow drives the device to navigate, and the electric energy is converted into kinetic energy to drive the device to navigate.

[0009] When the device is not in the working area and the power is insufficient, the control center directly controls the start of the vacuum pump, the vacuum pump sucks the air in the propeller, the pressure in the propeller is reduced, until the water pressure is greater than the pressure in the propeller, the water flow enters the propeller to impact the rotation plate to realize the function of generating electricity, in the moment when the water flow enters the propeller to drive the rotation plate, the motion sensor senses the movement of the rotation shaft and immediately feeds back to the processor, and then the controller controls the vacuum pump to be closed to avoid the situation that the vacuum pump sucks the water flow and causes the damage of the device, the generated electric energy can also be used as the power source of the navigation equipment and can also be used to supply the water pump and the water sprayer, and the device is driven to move forward by spraying water.

[0022] In addition, when a sudden situation occurs and the power is insufficient, the vacuum pump is arranged to suck the air in the propeller, so that the water pressure is greater than the internal pressure, the water flow enters the device, the water flow is converted into electric energy to drive the device to run back to the shore, and the device is prevented from sinking into the water bottom due to insufficient power.

[0041] Different devices select different valves 604 according to the depth of the working area, so that the valve 604 can be opened under the action of the water pressure in the working area, so that the water flow enters the propeller 5 along the flow guide groove 6 to impact the rotation plate 15, the rotation plate 15 moves to drive the rotation shaft 11 to rotate, and then the generator 12 is started to generate electricity.
