PURPOSE: An underwater survey glider is provided to produce electricity by rotating an impeller due to the flow of water generated when the underwater survey glider moves forward to operate a generator. CONSTITUTION: An underwater survey glider comprises a body(10), a rudder(30), a buoyancy tank(40), a controller(60), a generator(80), and an impeller(90) for a generator. The rudder is installed in the body. The buoyancy tank is formed inside the body. The controller controls the rudder and the pump(50). The generator is formed inside the body and is connected to a battery(70). A rotary shaft(81) is expanded to the outside of the body in the generator.

Description

Underwater survey glider}

The present invention relates to a underwater navigation glider of a new structure that can be generated by using the kinetic energy as the lifting in the water.

In general, the underwater navigation glider, as shown in Figures 1 and 2, the body 10 is made to withstand the hydraulic pressure of the deep water, and the fixed blade 20 provided on both sides of the body (10) ), The rudder 30 provided at the rear end of the body 10, the buoyancy tank 40 provided in the body 10, the pump 50 connected to the buoyancy tank 40, The controller 60 for controlling the rudder 30 and the pump 50, and a battery 70 connected to the controller 60 are provided.

Thus, when the underwater glider is submerged, when water is injected or discharged into the buoyancy tank 40, as shown in FIG. 3, the change in the buoyancy generated while the specific gravity of the underwater glider changes is different. By lifting up in the water, at this time, by the propulsion force acting on the fixed blade (20) is carried forward while lifting the glider approximately 45 ° angle forward.

In this case, according to the purpose, the body 10 of the underwater exploration glider is equipped with an exploration device such as a sonar or a camera and a wireless communication device, and can perform deep terrain or resource exploration.

The underwater navigation glider is moved forward by lifting due to the change in buoyancy generated by injecting or discharging water into the buoyancy tank 40 by using the pump 50, so the power efficiency is very high, even with little power for a long time There is an advantage that can be searched, it is widely used.

However, these underwater glider can minimize the power used when moving forward, but because the power required to operate the rudder 30 or other exploration or communication equipment is required, the propulsion using a screw Compared to other types of underwater exploration equipment, there was a problem that it was insufficient to significantly increase the exploration time.

The present invention has been made in view of the above problems, by using the kinetic energy of the lifting in the water, by providing an underwater exploration glider with a new structure that can significantly increase the exploration time.

The present invention for achieving the above object, the body 10, the fixed wing 20 provided in the body 10, the rudder 30 provided in the body 10, and the body 10 Buoyancy tank (40) provided inside the), the pump 50 connected to the buoyancy tank 40, the control unit 60 for controlling the rudder 30 and the pump 50, and the control unit 60 In the underwater navigation glider including a battery 70 connected to),

The generator 10 is provided inside the body 10 and is connected to the battery 70 and the rotation shaft 81 extends to the outside of the body 10, and is provided outside the body 10. Underwater exploration glider is provided, further comprising a power generating impeller 90 coupled to the rotating shaft 81 of (80).

Underwater navigation glider according to the present invention to the generator 80 by the flow of water generated when the underwater navigation glider is elevated by the difference in buoyancy generated by injecting or discharging water into the buoyancy tank 40 Since the connected impeller 90 rotates to operate the generator 80, it can generate electricity by itself and continuously perform exploration, thereby significantly increasing the exploration time.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

4 and 5, the glider for underwater navigation according to the present invention, the body 10 and the fixed wing 20 provided on both sides of the body 10 to be made to withstand the hydraulic pressure of the deep water depth And, the rudder 30 provided at the rear end of the body 10, the buoyancy tank 40 provided in the body 10, the pump 50 connected to the buoyancy tank 40, and The control unit 60 for controlling the rudder 30 and the pump 50 and the battery 70 connected to the control unit 60 are the same as in the related art.

At this time, the body 10 is additionally provided with an exploration device such as a sonar or a camera and a wireless communication device according to the exploration purpose of the underwater exploration glider.

In addition, a generator 80 connected to the battery 70 is provided inside the body 10, and an impeller 90 for power generation is coupled to the rotation shaft 81 of the generator 80.

The generator 80 is connected to the battery 70 through the voltage stabilization circuit 71, the rotating shaft 81 of the generator 80 is the body through the through hole 11 formed in the rear of the body 10 It extends out of 10. At this time, between the rotating shaft 81 and the through-hole 11 of the body 10 is waterproof.

The impeller 90 is configured in the form of a propeller, coupled to the rotary shaft 81 of the generator 80 to be located outside the body 10, to the flow of water generated when the underwater exploration glider is advanced in the water It rotates along to drive the generator 80. At this time, the rotation axis 81 of the generator 80 and the central axis of the impeller 90 is mounted to the body 10 to be parallel to the forward direction of the underwater navigation glider.

Therefore, when water is injected into or discharged from the buoyancy tank 40 with the pump 50 in the submerged glider submerged, as shown in FIG. 6, due to the difference in buoyancy acting on the body 10. Underwater exploration glider is advanced as the lifting in the water, accordingly, the flow of water is generated on the outer surface of the body 10 is the impeller 90 is rotated to drive the generator 80, the generator 80 is driven in this way The electricity generated as it is stored in the battery 70 is utilized.

The underwater exploration glider configured in this way generates power by using the flow of water generated when the glider is lifted, and thus stores the generated electricity in the battery 70 and utilizes it as a power source for various equipment, thereby dramatically increasing the exploration time. And, by dramatically reducing the number of times to stop the exploration to charge the battery 70, there is an advantage that can improve the exploration efficiency.

In particular, the generator 80 generates power by using the flow of water generated when the underwater exploration glider is advanced by the buoyancy, which is a natural phenomenon, it does not interfere with the exploration.

In the present embodiment, the impeller 90 is directly connected to the rotary shaft 81 of the generator 80 to illustrate that the generator 80 rotates 1: 1 by the impeller 90, but as necessary, It is also possible to increase the rotational speed of the generator 80 by installing a speed increase transmission in the middle of the rotation shaft 81.
