Description

{RESCUE TUBE LAUNCHING APPARATUS}

The present invention relates to a life tube launch device. More specifically, the present invention relates to a life tube launch device that can prevent a drowning accident by allowing the life tube to accurately reach and reach a position where a person is caught in the water and is waiting for the structure.

In general, accidents involving human life occur in various places such as water, sea, land, ice and ship.

In particular, human casualties that occur in water or marine areas are restricted in the rescue activities of the casualties due to the specific nature of the accident location.

In other words, the needy on the surface of the water drifts away from the land or the ship due to the influence of the flow velocity or the tide as the time passes after the accident, and the rescuer swims to the requestor, Such as a liferaft or a hand protruding.

However, in an urgent situation requiring urgent construction, it is not possible to quickly approach a requesting person without skilled marine rescue equipment such as aquatic security personnel or lifeboats, and the security of the rescuer as well as the demanding person can not be ensured according to the weather conditions.

Therefore, in order to solve the problem of the above-mentioned structural activity, a life-saving device equipped with a firearm-modified firearm such as a rifle, an air gun, or a gas gun can be attached to the firearm, A variety of life-saving launchers are being developed that launch air tubes and quickly deliver them to distant needy people.

An example of such prior art is shown in Fig.

1, a launch device 20 for launching a conventional air tube 10 includes a housing 21, a launch tube 22, a launch distance control tube 23, an elastic means 24, An elastic force adjusting means 25 and a triggering means 26. [

Therefore, after the air tube 10 is fixed in a cylindrical shape, the air tube 10 is mounted to the launch tube 22 through the opening of the tube tube 22. When the air tube 10 is mounted, the rotation lever is rotated counterclockwise, (24), thereby adjusting the elasticity of the coil spring in consideration of the distance of the person who waits for the structure.

When the trigger of the triggering means 26 is pulled after the user adjusts the extension of the firing distance control tube 23 to a predetermined distance in consideration of the position of the requester, So that the air tube 10 is fired at a position where there is a demanding person by elastic force, thereby rescuing the human life.

However, in such a conventional launch device 20, the volume of the launch device and the air tube is large, and there is a problem that it is difficult to carry or store an air tube having a particularly air pressure.

In addition, there is a problem that it takes a lot of time and time to mount each air tube in order to launch another air tube after firing one air tube.

 In addition, since the rotation lever is operated without precisely measuring the distance when the rotation lever is operated in setting and holding the distance between the launching device and the requesting person and setting the coil spring for launching the air tube, There is a problem in that the air tube is not properly transmitted to the requesting person due to an incorrect measurement of the distance to the requesting person.

Inside the tube 30, a tube bullet 40 and a propelling means 50, which will be described later, are accommodated.

The tube bullet 40 is accommodated in the bulb 30 and the tube bullet 40 is basically provided with a life tube 410 for constructing the bulb.

For example, the tube bullet portion 40 includes a life tube 410, an expandable compressed gas storage portion 420, a connection portion 430, a water detection sensor portion 440, and a traction rope 450, .

The life tube 410 is a structure for constructing a dehydrator. When the debris is contained in the tube 30, the gas is not injected. However, when it is discharged outside the tube 30 and falls on the water surface near the dehydrator, The water sensing sensor unit 440 operates to expand the compressed gas from the compressed gas storage unit 420 through the supply of the gas.

The expansion compressed gas storage part 420 functions to store a compressed gas for expanding the life tube 410.

The connecting portion 430 is provided between the life tube 410 and the expandable compressed gas storage portion 420 and maintains the normally closed state so that the gas stored in the compressed compressed gas storage portion 420 It does not flow into the life tube 410.

The water sensing sensor unit 440 opens the connection unit 430 when water is sensed and functions to introduce the compressed gas stored in the expansion compressed gas storage unit 420 into the life tube 410.

For example, the compressed gas may be carbon dioxide.

The tow ropes 450 are the means by which the rescuer tows the life tube. One end of the towing rope 450 is connected to the life tube 410 and the other end of the towing rope 450 is accommodated in the towing rope accommodating portion 80 fixed to the outer circumferential surface of the launching pipe 30 have.

In the air supply mode, a rescuer or the like may step on the air pump to supply air while the air pump and the injection / holding nozzle unit 520 are connected to each other. Of course, the gas tank storing the compressed gas may be connected to the injection / holding nozzle unit 520 and supplied.

When the air is introduced through the injection / holding nozzle unit 520, the air introduced into the empty space of the thrust providing medium storage unit 510 is filled, and the internal pressure is increased. In this way, when the internal pressure is increased, the thrusting medium storage unit 510 receives the thrust force toward the front of the tube 30, and the two nozzles 521 and 522 formed at both ends of the three nozzles 521, 522 and 523 The drive force providing medium storage unit 510 and the thrust force providing medium storage unit 510 and the thrust force providing medium storage unit 510 are provided before the rescue triggering unit 60 is operated, The attached bullet bullet 40 is not released from the bullet tube 30. [

The triggering means 60 is means for operating the propelling means 50 by the user's manipulation. The two nozzles 521 and 522, in which the projections are formed, are bent inward when the rescue self-triggering means 60 is operated to release the holding of the propulsion-providing medium storage portion 510 by the projections, A propulsion providing medium storage unit 510 that acquires propulsion force by the received air pressure and a tube bullet unit 40 attached to the propulsion supply medium storage unit 510 are emitted from the launch tube 30.

If this laser distance measurer 710 is only one example of the distance measurer, the radar distance measurer can be applied to the distance measurer.

The acceleration sensor 720 performs a function of measuring the current angle of the launch tube 30. Such an acceleration sensor 720 is an example of an angle measurement sensor, and a gyro sensor can also be applied as an angle measurement sensor.

The firing angle calculation unit 730 calculates the firing angle of the tube bullet 40 according to the distance measured by the laser distance meter 710 and the weight of the tube bullet 40 stored in advance in the memory And calculates a firing angle for the firing angle.

The auditory information providing unit 740 may be configured to provide information about the angle matching to the user when the current angle measured by the acceleration sensor 720 and the emitting angle calculated by the emitting angle calculating unit 730 are within a predetermined deviation range It performs the function to provide it.
