First, the overall structure of the aerial drop lifter according to the embodiment of the present invention will be described. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram for explaining the overall configuration of a public release undereventing apparatus according to an embodiment of the present invention; FIG. 1, the life-saving device lifted in the air according to an embodiment of the present invention includes a lifeboat 100, a parachute structure 200, a disconnecting part 300, a navigation part 400 and a life raft 500 do.

The lifeboat (100) is dropped from the air vehicle (10) in a distress area due to a marine accident. When the lifeboat 100 is aerated, the parachute structure 200 is connected to the lifeboat 100 and includes a parachute deployed to slow down the speed of the lifeboat 100. As described above, since the speed of dropping the lifeboat 100 is reduced by using the parachute, the impact applied to the lifeboat 100 can be reduced. The disconnecting part 300 is for releasing the connection between the parachute of the parachute structure 200 and the lifeboat when the lifeboat 100 lands on the water surface after falling. To this end, the disconnecting part 300 automatically cuts the parachutes connected to the lifeboat 100 after the lifeboat 100 has fallen. The navigation unit 400 receives the remote control signal and operates the lifeboat 100 to approach the lifeboat 100 within a predetermined distance according to the received remote control signal when the lifeboat 100 is placed on the water surface after falling , To launch a life punishment. Also, when the lifeboat 500 approaches the lifeboat 100 within a predetermined distance to the victim, at least one lifeboat automatically inflates so that the survivor can ride the lifeboat.

As described above, according to the embodiment of the present invention, after the lifeboat 100 is dropped from the airplane, the lifeboat 100 is moved to the vicinity of the victim and the lifeboat is launched around the victim. This makes it possible to rescue the victims more safely and quickly because the victims do not have to travel to life jackets themselves.

Next, the parachute structure 200 and the disconnecting part 300 in the configuration of the aerial drop lifter according to the embodiment of the present invention will be described in more detail. 2 and 3 are views for explaining a parachute structure 200 according to an embodiment of the present invention. The parachute structure 200 includes a parachute pack 210 and a parachute 220. The parachute pack 210 is fixed to the lifeboat 100 and automatically unfolded when the lifeboat 100 is dropped in air. The parachute 220 is connected to the parachute pack 210 and stored in the parachute pack 210. The parachute 220 is unfolded as the parachute pack 210 is unfolded. Thus, the dropping speed of the lifeboat 100 can be reduced.

2 and 3, the parachute line 230 connects the parachute 220 to the lifeboat 100 through the parachute pack 210. Here, the part 300 is connected to the middle of the parachute string 230. The disconnecting part 300 automatically cuts the rescue shroud 230 when the lifeboat 100 lands on the water surface after being aerated. The connection failure section (300) automatically cuts the parachute line (230) by water pressure when the connection section (300) is submerged. The connection failure section 300 may further include a weight 301 for locking the connection section 300 because the connection section 300 is connected to cut the parachute line 230 so that the connection section 300 should be submerged in water.

Hereinafter, a configuration for cutting the parachute string 230 of the connection part 300 will be described in detail. 4 and 5 are cross-sectional views of a connection part according to an embodiment of the present invention. The connector 300 includes a receiving tube 310, a cutting tube 320, a cutter 330, a cutting spring 340, a lock cylinder 350, a lock plate 360, a lock pin 370, 380).

The receiving tube 310 is hollow cylindrical with both open ends and accommodates the parachute string 230 through both open ends. Cutting tube 320 is vertically connected to receiving tube 310 and has a hollow shape. An end of the cutting pipe 320 farthest from the receiving pipe 310 is closed and a cutting hole 311 is formed in a portion of the cutting pipe 320 connected to the receiving pipe 310. A cutter 330 and a transmission spring 340 are formed inside the cutting pipe 320. A cutting spring 340 and a cutter 330 are sequentially connected in the direction of a portion connected to the receiving tube 310 from the inside of the cut tube 320 at the closed end. The cutting spring 340 may be a helical compressive spring and the cutter 330 may be a cutter for cutting the parachute string 230. 4, the cutter 330 is formed with a lock hole 331 vertically penetrating the cutter 330 at one side thereof. The lock hole 331 is formed in the cutter 330 so that the lock pin 370 can be inserted The shape and size of the lock pin 370 and the same shape and size within the tolerance. The disconnecting part 300 is installed with the first lock pin 370 inserted into the lock hole 331 of the cutter 330. As shown in the figure, when inserted into the lock hole 331, the cutting spring 340 is in a compressed state.

Meanwhile, the lock cylinder 350 is formed in a vertical direction to the cut tube 320, and is formed into a hollow cylindrical shape. A lock plate 360, a lock pin 370 and a lock spring 380 are formed in the lock cylinder 350. The end farthest from the cutting pipe 320 in the lock barrel 350 is closed and a connection hole 351 is formed in a portion connected to the cut pipe 320. The lock plate 360 and the lock pin 370 are sequentially connected in the direction of the portion connected to the cut tube 320 from the closed end of the lock cylinder 350. [ The lock spring 380 may be a helical compressive spring. The lock plate 360 is formed in a disk shape. The lock pin 370 protrudes vertically downward from the lock plate 360. A plurality of inflow holes 353 are formed in the lower side of the lock barrel 350 and the seawater is introduced into the lock barrel 350 through the inflow hole 353 when the connecting part 300 is locked in the seawater. When seawater is introduced, pressure due to seawater is applied to the lock plate 360, and the pressure applied to the lock plate 360 exerts a compressive stress on the lock spring 380. As shown in FIG. 5, as the seawater is introduced, the compressive stress becomes larger, and if the compressive stress is higher than the constant value of the lock spring 380, the lock spring 380 is compressed. When the lock spring 380 is compressed, the lock plate 360 is raised, and the lock pin 370 connected thereto is also raised. The lock pin 370 moves through the connection hole 351 and can be inserted into or withdrawn from the lock hole 331 formed on one side of the cut pipe 320. Therefore, when the lock spring 380 is compressed by the seawater, the lock pin 370 is lifted and the lock pin 370 is pulled out from the lock hole 331 formed on one side of the cut pipe 320. 5, when the lock pin 370 is pulled out of the lock hole 331, the compressed state of the cutting spring 340 expands, and due to the expansion of the cutting spring 340, Moves into the receiving pipe 310 through the hole 331, and cuts the parachute string 230. Thus, when the connector 300 is submerged in seawater, the rescue shackle 230 is automatically cut, and the lifeboat 100 and the parachute 220 are separated.

6 is a cross-sectional view of a connection part according to another embodiment of the present invention. 4 and 5, a part of the parachute string 230 may be formed of a water-soluble material, and the connecting part 300 may be formed of a material that melts in the water of the parachute string 230 And may be a cylindrical sinking pipe 390 surrounding a portion formed of a material. The sinking pipe 390 is formed of a material having a specific gravity higher than that of water so that the portion formed of the water-soluble material of the parachute string 230 sinks well in the water. It is preferable that the sinking pipe 390 is made of a metal having a high specific gravity such as lead. In addition, the sinking pipe 390 is submerged in water, and a plurality of penetration holes 391 are formed in the portion of the parachute string 230, which is formed of a material dissolving in water, so that the water penetrates well. Accordingly, when the lifeboat 100 is air-dropped and then rests on the water surface, the disconnecting part 300 formed of the sinking pipe 390 sinks the water-soluble part of the parachute string 230 into the water, So that the parachute string 230 is cut.

As described above, after the lifeboat 100 and the parachute 220 are separated from each other, the lifeboat 100 moves to the position where the victim is located according to the remote control signal. To this end, the life-saving apparatus 100 includes a navigation unit 400. 7 is a block diagram for explaining a configuration of a navigation unit according to an embodiment of the present invention. 7, the operation unit 400 includes a communication unit 410, an antenna 411, a water jet 420, an input unit 440, a storage unit 450, a position information processing unit 460, a heating unit 470 ), A forward unit 480, and a control unit 490.

The communication unit 410 can receive at least one of the remote control signal and the remote launch signal through the connected antenna 411. The water jets 420 lift water below the lifeboats 100 and spray the water behind the hulls to provide a driving force for the lifeboats 100 to move. The water jets 420 include variable nozzles and adjust the direction in which the lifeboat 100 moves by changing the direction of spraying water through the variable nozzles. The controller 490 may control the water jet 420 to move the lifeboat 100. [ The launching unit 450 is for launching at least one liferaft 500 mounted on the lifeboat 100 on the surface of the water.

The input unit 440 is for receiving the key operation of the user for controlling the operating unit 400 or for setting the specific parameters for the operating unit 400. [ If there is an input for a specific key, the input unit 440 generates an input signal corresponding to the key, and transmits the input signal to the controller 490.

The storage unit 450 stores data necessary for the operation of the operation unit 400 and operation result data of the operation unit 400 and the like. This data includes location information of the survivor, location information of the lifeboat 100 that is constantly being changed.

The position information processing unit 460 continuously receives the position information from the GPS satellites and transmits the received position information to the control unit 490. Then, the control unit 490 transmits the location information to a location display device (not shown) provided by the rescuer through the communication unit 410. [ Then, the rescuer can continuously track the position of the lifeboat 100 through a location display device (not shown).

The heat generating unit 470 is mounted on the lifeboat 100 to radiate heat and facilitate the location of the lifeboat 100 at night. That is, according to the heat generated by the heat generating unit 470, the rescue person can easily confirm the position of the lifeboat 100 through the night vision system.

The control unit 490 may receive the position of the victim by coordinates (e.g., latitude, longitude, altitude) through the input unit 440 or may receive the remote control signal through the communication unit 410. Then, the controller 490 controls the water jet 420 to move the lifeboat 100 according to the input coordinates or the received remote control signal. In addition, the control unit 490 can receive the remote launch signal through the communication unit 410. Then, the launcher 450 is controlled according to the remote launch signal so that the lifeboy 500 is launched.

According to one embodiment, the rescuer aboard the air vehicle 10 can input the position of the victim, that is, the coordinates through the input unit 440. Then, the control unit 490 stores the position of the victim in the storage unit 450 as coordinates. The control unit 490 continuously receives the current positional information (coordinates) from the GPS satellites through the positional information processing unit 460 and outputs the current position information (coordinate) to the current position of the lifeboat 100 (Coordinates) continuously. The control unit 490 then controls the water jet 420 to move from the current location of the identified lifeboat 100 to the location of the destroyer stored in the storage unit 450.

According to another embodiment, the rescuer aboard the air vehicle 10 can remotely control the lifeboat 100 to move to the position of the victim through the remote controller 11. [ That is, the remote controller 11 can transmit a remote control signal to cause the lifeboat 100 to move to the position of the victim in accordance with the manipulation of the rescuer. The communication unit 410 receives the remote control signal from the remote controller 11 and transmits the received remote control signal to the controller 490. [ Upon receiving the remote control signal through the communication unit 410, the control unit 490 controls the water jet 420 in accordance with the remote control signal. That is, the controller 490 can control the water jet 420 to have a moving direction and a speed corresponding to the remote control signal.

According to another embodiment, the rescuer may remotely control the life jacket 500 from the lifeboat 100 by operating the remote controller 11. That is, the remote controller 11 may transmit a remote launch signal from the lifeboat 100 to cause the life vest 500 to launch, according to the operation of the rescuer. Upon receiving the remote launch signal from the remote controller 11, the communication unit 410 transmits the received remote launch signal to the controller 490. [ When the control unit 490 receives the remote launch signal through the communication unit 410, the control unit 490 controls the launch unit 450 according to the remote launch signal. That is, the control unit 490 controls the launch unit 450 so that at least one lifeline 500 mounted on the lifeboat 100 is launched on the water surface according to the remote launch signal.

As described above, after the lifeboat 100 is brought within a predetermined distance of the victim by inputting the destructor position of the rescuer or by remote control using the remote controller 11, a survivor 500 mounted on the lifeboat 100 The life jacket 500 is launched so that the user can easily ride. Thereafter, according to an embodiment of the present invention, the life vest 500 inflates automatically or manually, by remote control, so that the survivor can easily ride on the life vest 500. This will be described in more detail. 8 to 10 are views for explaining a life jacket according to an embodiment of the present invention. 8-10, a life raft 500 includes a life raft body 510, a receiving portion 520, a tree rejection 530, a gas injection portion 540, and a gas tank 550.

The launching unit 450 loads at least one lifeline 500 and launches the lifeline 500 mounted by remote control, as described above. After the life raft 500 is launched, the life raft main body 510 is automatically swollen so that the survivor can ride on the life raft 500. 9, a receiving unit 520, a tree rejecting unit 530, a gas injecting unit 540, and a gas tank 550 are sequentially connected to each other inside the life raft body 510. As shown in FIG.

The rescuer aboard the air vehicle 10 can manipulate the remote controller 11 to cause the life raft body 510 to automatically inflate. That is, according to the operation of the rescuer, the remote controller 11 can transmit a remote infusion signal that causes the life raft body 510 to automatically inflate. The receiving unit 520 may receive the remote injection signal.

The gas tank 550 compresses and stores the gas that causes the lifesaver body 510 to swell up to have a buoyant force. This gas is preferably nitrogen. The gas injection unit 540 is for injecting the gas of the gas tank 550 into the life of the beehive body 510 according to the operation of the tree rejection 530. The tree rejection 530 operates the gas injection unit 540 so that the gas injection unit 540 injects gas of the gas tank 550 into the life of the beehive body 510.

The gas injection unit 540 is formed in a hollow cylindrical shape. A barrier film 541 is formed at a portion where the gas injection unit 540 and the gas tank 550 are connected to prevent the gas from flowing out until the gas in the gas tank 550 is injected into the beating body 510. That is, the barrier film 541 seals the inlet of the gas tank 550 to prevent outflow of gas in the gas tank 550. At least one of the gas injecting unit 540 is provided at the side of the gas injecting unit 540 so that the gas discharged from the gas tank 550 is injected into the life raft body 510 when the gas of the gas tank 550 is injected into the life- An injection hole 543 is formed. Since the gas injection unit 540 is located inside the life raft body 510, the injection hole 543 can be said to be a passage connected to the life raft body 510. The gas injection portion 540 is provided with an injection pin 545 and a pair of injection pins 545 which are spaced apart from the barrier film 541 by a predetermined distance so as to face the barrier film 541 and along the outer periphery of the injection pin 545 An injection spring 547 is formed.

The tree rejection 530 is formed in a hollow cylindrical shape and a bobbin 531 and a trigger 535 in which a trigger string 533 is wound are formed inside the tree rejection 530. On the other hand, the end of the injection pin 545 opposite to the prevention film 541 is formed protruding into the tree rejection 530. 9, one end of the trigger 535 is formed to be spaced apart from the end of the injection pin 545 by a predetermined distance, before the gas is injected into the life expectancy main body 510. As shown in Fig. The other end of the trigger 535 is tied with a trigger string 533, and the trigger string 533 is wound around the bobbin 531. As shown in FIG. 10, when the receiving unit 520 receives the remote injection signal, the remote injection signal causes the bobbin 531 to wind the trigger bar 533. One end of the trigger 535 pushes the injection pin 545 to move the injection pin 545 in the direction of the gas tank 550 when the bobbin 531 is rotated to wind the trigger string 533 according to the remote injection signal. Apply physical pressure to

9, unless a predetermined compressive stress is applied to the injection spring 547 before the gas is injected into the life expectancy main body 510, the injection pin 545 is separated from the prevention film 541 by a predetermined distance . When one end of the trigger 535 presses the injection pin 545 and physical pressure is applied so that the injection pin 545 moves toward the gas tank 550, the injection spring 547 is subjected to a predetermined compressive stress All. Then, the injection spring 547 is compressed, and at the same time, the injection pin 545 is moved to rupture the prevention film 541. The gas in the gas tank 550 flows out into the ruptured gap of the prevention film 541 and flows into the life raft body 510 through the injection hole 543. [ Then, the life raft body 510 automatically inflates. Accordingly, the victim can ride on the swollen life raft body 510, that is, the life raft 500.

While the present invention has been described with reference to several preferred embodiments, these embodiments are illustrative and not restrictive. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
