BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic extension tube for lifesaving and a dron for carrying the same.

Generally, when rescuing a person who has fallen into the water from a river or sea, the rescuer swims directly to hold the person in the water and swim to the dry land to rescue it or to throw it at the end of an object such as a rope, When you grab it, the rescuer pulls the rope or the like to rescue it.

When a rescuer swims directly and grabs a man in the water and swims to the ground, there is a great risk that the rescuer will be tired when he swims to the ground and suffer a relative drowning accident.

In the case of rescuing a person who has fallen into the water by using an object with a rope, there may be a situation where an object such as a rope or a rod is not in the surroundings in case of an emergency, It may happen that it is difficult to do so.

Particularly, in the case of the above-mentioned structural methods, there is a limitation in the number of persons who can be rescued, and there is a difficulty in rescue when a situation occurs in which people are swept away by seawater due to sea currents or coastal breaking waves.

Also, in the case of lifesaving drones carrying the existing tubes, the size of the tubes is so large that the drones' gas, various components such as batteries and chargers must also be enormous, and a specially designed drones are required. Also, since the volume of the tube is large, there is a limitation on the number of tubes that can carry the air resistance, and it is difficult to fly for a long time due to the gas giantization.

Therefore, the present invention can be applied to general hunting drones and utilized for lifesaving structure, and it is possible to carry out automatic lifting tube transportation and dropping part to existing lifesaving drones, An automatic expansion tube for lifesaving and a dron for carrying the same.

More specifically, the length of the first arm 232-1 may be longer than that of the second arm 232-2. This means that the first arm 232-1 and the second arm 232-2 are slidably operated with a time difference.

Therefore, when the gear motor 232-3 is driven, a time difference of the sliding operation is generated by the difference between the length of the first arm 232-1 and the length of the second arm 232-2.

Accordingly, the automatic deployment tube 100 carried through the above-described operation of the automatic expansion tube transportation and dropping unit 230 can be removed from the dron 200 (see FIG. 4).

3, the automatic expanding tube transporting and delivering unit 230 may be configured such that the sliding operation of the first arm 232-1 and the sliding operation of the second arm 232-2 are time- The first pinion gear and the second pinion gear may have different numbers of teeth and sizes of teeth.

The first pinion gear meshes with the gear motor 232-3 and the gear of the first arm 232-1 and the second pinion gear meshes with the gear motor 232-3 and the second arm 232-2. And is disposed so as to engage with the < Desc / Clms Page number 2 >

That is, the first arm 232-1 and the second arm 232-2 of the automatic expanding tube transporting and dropping unit 230 according to another embodiment are arranged such that the number of teeth and the size of the first and second pinion gears As shown in Fig.

2, the automatic expanding tube transporting and dropping unit 230 may include a distance measuring sensor 233 and a driving control unit 234. [

The distance measuring sensor 233 measures the falling height between the water surface and the drone body 210.

The drive control unit 234 functions to drive the gear motor 232-3 on the basis of the detection signal of the distance measuring sensor 233 when the fall height reaches the preset height or to operate the gear motor 232-3 10 to activate or deactivate the drive of the gear motor 232-3.

In addition, the automatic expanding tube transporting and delivering unit 230 may further include an additional function.

For example, it may further include at least one or more of a camera section for photographing a position image of the rescuer, an ultrasonic sensor section for detecting the position of the rescuer through ultrasonic waves, and a thermal sensor section for sensing the temperature of the rescuer to detect the position of the rescuer.

Therefore, by using the automatic extension tube for lifesaving structure according to the embodiment of the present invention and the drone for transporting it, it is not necessary for the rescuer to directly access the victim with the tube, thereby preventing the accident caused by the lifesaving structure .

In addition, it is possible to mount a plurality of the development tubes to the drone, and to provide a plurality of the spreaders at the same time, so that it is very easy to structure the life.
