In addition, a rotation rod 140 is rotatably coupled to an end of the fixed arm 130, and the rotation rod 140 is not shown, but the rotation angle is adjusted by a rotation motor built in the drone main body 100. As it is configured to be ascending, descending (descend), forward flight (forward), backward flight (backward), right roll (roll right), left flight (roll) by adjusting the angle of the rotating rod 140 left, yaw left, or yaw right may be possible, and since this is a general technique implemented in currently available drones, a detailed description thereof will be omitted.

And, the rotor motor 150 is fixed to the rotating rod 140, a rotor (not shown) is mounted on the motor shaft of the rotor motor 150, the rotor (usually 'propeller' according to the drive of the rotor motor 150) ') Is rotated while flying the drone body (100).

As such, it includes technologies already implemented in commercial drones, and in addition, it is configured to be able to fly for a long time for at least 10 hours. To this end, the first and second batteries BT1 and BT2 are mounted in the lower body BD on which the camera 120 is mounted. In this case, the first and second batteries BT1 and BT2 may be storage batteries, and in particular, the first and second batteries BT1 and BT2 may be dually installed so as to increase the use time of the battery.

In addition, the upper surface of the drone main body 100 is provided with a predetermined depth installation groove 102. In addition, a seating protrusion 104 protrudes from the bottom surface of the installation groove 102 to a predetermined height, and the partitioning plate 106 is seated and fixed to the seating protrusion 104 and partitioned into a lower space and an upper space. .

At this time, the lower space partitioned by the partition plate 106 is provided with a helium gas cylinder 160, the helium gas cylinder 160 is connected to the gas supply pipe 162, the gas supply pipe 162 is a solenoid valve type Opening and closing valve 164 having a, end of the gas supply pipe 162 is connected to the inlet end of the gas pump 170.

In addition, the balloon supply pipe 172 is connected to the outlet end of the gas pump 170. On the other hand, the balloon 180 is provided in the upper space partitioned by the partition plate 106, the balloon 180 is the injection hole 182 is fixed on the partition plate 106.

In addition, an end portion of the balloon supply pipe 172 is closely connected to the injection hole 182 of the balloon 180 through the partition plate 106. Therefore, when the on-off valve 164 is opened and the gas pump 170 is operated by the control of the controller 200 to be described later, helium gas inside the helium gas cylinder 160 is injected into the balloon 180, as shown in FIG. 3. Inflated to produce buoyancy to fly.

On the other hand, when the gas pump 170 is reversely rotated, helium gas charged in the balloon 180 is recovered into the helium gas cylinder 160 again, and in the process, the balloon 180 is split and the upper space is returned to its original state. Housed in the opening / closing valve 164 when the helium gas is recovered. As described above, the present invention may provide buoyancy to the drone main body 100 by floating the balloon 180 by using helium gas lighter than air to maintain the air hole, that is, the hovering state for a long time in the air.

In particular, the parachute cover 196 is disposed so as to be positioned at the side of the drone main body 100 after the end completely covers the drone main body 100, and is bound by a wire 194.

A plurality of idle rolls ROL are installed on the hollow portion 108 along the outer circumference of the installation groove 102 in which the balloon 180 is installed, and the wire 194 passes through each idle roll ROL. After passing through each side of the drone main body 100 at each vertex portion of the hexagonal drone main body 100, the parachute cover 196 is bound.

Therefore, the rubber band is inserted into the waist dance so as to pull the end of the rubber band, as the waist dance is tightened, the wire 194 is wound around the wire drum 192 by rotating the wire motor 190 so that the wire 194 is pulled down and the parachute cover 196. Is tightly pressed to the surface of the drone body 100 while pressing the balloon 180 is fixed.

Then, when the balloon 180 swells, the wire motor 190 rotates in reverse and releases the wire 194 to swell in the form shown in the example of FIG. 3 with the balloon 180 swelling. Here, the reason for having the parachute cover 195 is to protect the balloon 180 in the form of a tube, which is caused by a sudden change in the weather during sudden hovering, breakage caused by birds, rain, snow, thunder lightning, etc. In order to prevent the risk of damage in advance, in particular, if the balloon 180 is blown due to an inadvertent reason, when the drone main body 100 falls as it is, the drone main body 100 is largely damaged, so in this case, the parachute cover naturally This is to prevent the sudden drop of the drone main body 100 by the air buffer by performing the parachute function (195) to minimize the damage.

In addition, the main buoyancy is generated due to the helium gas charged in the balloon 180, but because the air enters the space between the balloon 180 and the parachute cover 196, the buoyancy by the air is also applied, the drone main body 100 is much more You can easily come up.

As described above, the drone can move for a long time and move in one place without continuously moving, and when the fine dust concentration indicator falls due to a natural disaster or the like, the drone call signal generation unit 600-1 receives a signal. When sent, the drone call signal receiving unit 100-1 of the drone may receive the signal and may save lives of people near the fine dust concentration indicator with the drone.

In this case, the drone call signal generator 600-1 may generate a signal at the same time as the fine dust concentration indicator falls, or a signal may be generated by an operation in an app installed in a remote controller or a mobile phone, but the present invention is not limited thereto. .
