An embodiment of the present invention will be described in detail with reference to the accompanying drawings 1 to 7 .

1 and 2, the underwater moving body (hereinafter 'underwater moving body') that forms a cavity through the hot gas injection of the present invention is high temperature to prevent high-speed movement due to the resistance of water when applied to the underwater high-speed moving body By spraying the heated air to the outer periphery of the underwater vehicle 10 to form the cavity 20, the underwater vehicle 10 can move at high speed in the water while minimizing the resistance received from the water, and the underwater sterilization device When applied to a low-speed moving body, such as, by spraying air heated to a high temperature to the outer periphery of the underwater moving body 10, it is an invention to sterilize the underwater moving body 10 around the high-temperature gas.

Therefore, the underwater moving body 10 of the present invention, as shown in FIG. 3, the moving body 100, the heating unit 200, the cavity forming unit 300, the hot gas injection unit 400, the propulsion unit 500, the battery 600 , a compressed air tank 700 , an air supply pipe 800 , and a controller 900 .

Specifically, the underwater movement forming a cavity through the hot gas injection of the present invention,

a first space 101 and a second space 102 separated and partitioned so as to maintain mutual airtightness; a moving body 100 formed therein;

The heating unit 200 is formed in the first space 101 and heats the air supplied from the compressed air tank 700 to the first space 101 through the supply pipe 800 to a predetermined temperature to generate a high-temperature gas. Wow;

a cavity forming part 300 formed at the front end of the moving body 100 and allowing the cavity to be easily formed by external features when hot gas is sprayed to the outside;

a high-temperature gas injection unit 400 configured to inject the high-temperature gas in the first space 101 to the outside;

a compressed air tank 700 formed in the second space 102 and storing compressed air;

It is characterized in that it includes an air supply pipe 800 for supplying the compressed air stored in the compressed air tank 700 to the first space (101).

Referring to FIG. 4 , the moving body 100 is a configuration corresponding to the body of the underwater moving body 10 according to the present invention, and is formed in a streamlined shape having a predetermined length to provide an internal space in which each component is installed.

Here, in the inner space of the moving body 100, as shown in FIGS. 5 and 6, a first space 101, a second space 102, and a third space 103 are formed, and the spaces are mutually airtight. It is separated and partitioned by a partition wall formed to be maintained.

5 and 6 , the first space 101 is an internal space formed from the middle of the moving body 100 to the tip (head) of the moving body 100 to which the cavity forming part 300 is connected, and a heating part (200) is a space formed.

At this time, the air stored in the compressed air tank 700 installed in the second space 101 is supplied to the first space 101 through the air supply pipe 800 to be heated to become a high-temperature gas, and then to the outside of the moving body 100 . is sprayed with In this case, the cavity 20 is formed around the body 100 of the moving body 100 as shown in FIG. 2 by the injected hot gas.

The reason for forming the cavity 20 in the present invention is for high-speed movement of the moving body 100 and surrounding sterilization.

The cavity 20 reduces the resistance of the moving body 100 in contact with water during high-speed movement of the moving body 100 to achieve a higher speed under the same driving force. In addition, when the moving body 100 is moved at a low speed, the cavity 20 is not intended to move at a high speed, but serves as a high-temperature gas bag to sterilize the vicinity of the moving body 100 .

Referring to FIG. 5 , the second space 101 is an internal space formed from the middle of the moving body 100 to the stern (tail), and the motor 510 of the propulsion unit 500, the battery 600, and compressed air. It is a space in which the tank 700 and the controller 900 are formed, and the second space 101 is separated and partitioned by a partition wall to maintain mutual airtightness with the first space 101 .

Here, the reason that the second space 101 and the first space 101 are separated by a partition wall is that first, the first space 101 is a space in which air is heated and high-temperature gas exists, so that the propulsion unit ( 500) to block the motor 510, the battery 600, the compressed air tank 700, and the controller 900 from being exposed to the high temperature of the high-temperature gas, and secondly, through the high-temperature gas injection unit 400, the external To prevent the motor 510, the battery 600, the compressed air tank 700, and the controller 900 of the propulsion unit 500 from being submerged in water when a certain amount of water infiltrates into the first space 101 it is for

Referring to FIG. 6 , the third space 103 is separated from the first space 101 by a partition wall, and is formed between the plurality of second hot gas injection holes 440 and the first space 101 .

The air supplied to 101 is heated to 100~1500°C to generate high-temperature gas.

In particular, the induction method is an indirect heating method that induces heat in the object itself by using a magnetic field. It has excellent energy efficiency and good stability, and does not generate much heat in the device itself. It is possible to heat the air supplied from the compressed air tank 700 stably and quickly in one space 101 .

On the other hand, the cavity 20 can be formed only by injecting unheated air to the outside of the moving body 100 in the water, but when the hot gas in which the air is heated is sprayed in the water, the high temperature of the injected hot gas As the water in the water adjacent to the moving body 100 is vaporized by the cavity 20 is obtained the effect of forming a larger.

Therefore, the present invention heats the air injected to the outside through the heating unit 200 to a high temperature to form an effective cavity so that high-speed movement of the underwater vehicle is possible, and at the same time, when moving at low speed, the hot gas sprayed around the underwater vehicle Make it possible to sterilize the sterilized object.
