Description

Unmanned air vehicle for fog dissipation and snow removal.

The present invention relates to an unmanned aerial vehicle for fog and snow removal, and more particularly, to an unmanned aerial vehicle for fog and snow removal, and more particularly, to an aerial vehicle, In order to improve the condition, it is necessary to maintain or move a certain height by the propeller in order to achieve the snow removal and drying, and the mist can be removed by spraying the jet engine, the dispersing agent or the snow remover, , And a unmanned aerial vehicle for snow removal and snow removal, which serves as a multipurpose function for removing snow piled up on roofs of buildings and the like.

Fog is a phenomenon that consists of water vapor or supersaturated floating droplets and exists in the atmosphere near the surface. It means a case where the horizontal visibility is less than 1 km.

The generation of these fogs largely depends on evaporation and cooling, and is therefore largely divided into cooling fog and evaporation fog.

Here, the cooling fog is a fog that occurs when the temperature of the air layer in contact with the ground becomes lower than the dew point, and there are radiant fog, entrainment fog, and power fog.

Radiation fog refers to the fog generated by the cooling of the air tangential to the surface due to radiative cooling of the earth's surface. The fog occurs when warm and humid air moves on a cold surface. It is called a sea urchin with fog.

Fogs can interfere with the operation of various transportation means such as airports and roads, and sometimes cause serious damage such as personal injury.

In addition, fog causes economic and temporal loss as a cause of flight cancellation or delay.

Fog mitigation studies have been started in the 1910s in response to these fogs. Conventionally known methods for fog mitigation are classified according to the ambient temperature. In the case of the ambient temperature, images are classified as normal fog and normal fog is classified as cold fog. When the temperature is above 0 ℃, it spreads the calcium chloride (CaCl2) or sodium chloride (NaCl), which is a hygroscopic material acting as an artificial condensation nucleus (cloud seed), and acts as a condensation nucleus to generate suspended droplets such as water vapor or supersaturated droplets It is typical to reduce fog through the condensation process and to reduce fog by spraying liquid nitrogen, dry ice, and artificial ice crystal nucleus agent AgI, which are artificial cooling mediums in the cold fog occurring at subzero temperature.

Currently, studies to reduce such fog in specific regions or target regions are being actively studied in roads, bridges, and the like.

However, spraying methods for fog mitigation materials in narrow areas such as roads and bridges have been actively researched and developed, but in the case of airport runways that are wider and wider area, research and development are insufficient with a lot of energy and maintenance cost.

Especially, in the case of airports, unlike roads, when an aircraft takes off and land, it is necessary to reduce fog to the vertical visibility outside the horizontal clearance distance. Especially, in the case of the secondary fog, it can reach tens to hundreds of meters from the indicator.

To date, known fog mitigation techniques have been studied with only a few meters of fog at the surface.

For example, when a jet aircraft is operated on a foggy runway to use a high-speed airplane engine at an airport, fog droplets may evaporate into water vapor or convection may occur, causing fog to dissipate. However,

This has the problem that excessive fuel consumption and jet airplane must run on the runway, and fog above a certain height is not easy to dissipate.

In addition, there are various problems such as fog coming back from the mist coming in from the back.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and it is an object of the present invention to provide a fogging method for improving the visibility of an airport runway, a port facility, a highway, a national highway, It is possible to remove the fog by spraying the jet engine, spraying agent or spraying agent on the roof of the plastic house, roof, etc. The purpose of this paper is to provide a unmanned aerial vehicle for multi-purpose function of removing snow accumulation and snow removal.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

As shown in FIGS. 1 to 4, the configuration of the UAV 100 (hereinafter referred to as an unmanned aerial vehicle) for fog dissipation and snow removal according to the first embodiment of the present invention is schematically described below.

At least one or more than one jet engines 160 installed below the main body 120 are installed in the main body 120. The main body 120 includes a main body 120 on which the cargo is loaded, a propeller 140 provided on the main body 120, And a control means (200) for controlling the unmanned aerial vehicle.

The main body 120 has a hemispherical shape and protrudes upward and has a circular or polygonal shape at the bottom, and a dispersing agent, a desiccant or a snow remover 180 for fogging or snow removal is loaded therein.

The dissipative agent or the snow removing agent is preferably composed of calcium chloride (CaCl2), sodium chloride (NaCl), liquid nitrogen, dry ice, silver iodide (AgI).

This can be easily changed by the user's choice, and is included in the technical idea of the present invention.

In addition, a motor 142 for driving the propeller 140 is provided on the upper portion of the main body 120. The motor 142 is driven by a known moving means (not shown) such as a hydraulic pressure or a rail, And the propeller 140 can be freely changed.

In addition, it is preferable that the propeller 140 has a propeller of a helicopter, and the rotation angle of the propeller 140 is changed to easily change the traveling direction of the unmanned aerial vehicle 100.

The jet engine 160 is provided under the main body 120 and is freely changed from -10 ° to -170 °. The jet engine 160 is rotated by 360 ° from the bottom of the main body 120, And is freely changeable by the rotating means of the motor.

Of course, the jet engine 160 is provided so that the outside air flows into the upper portion and the lower portion discharges into the lower portion.

It is more preferable that the dissipating agent or the snow removing agent 180 loaded on the main body of the jet engine 160 is supplied to the jet engine 160 through the jet line 182 and jetted simultaneously.

4, the control means 200 controls the rotation and the position of the motor 142 provided in the main body 120, the injection and injection angle of the jet engine 160, And an internal equipment control unit 260 for transmitting and receiving the inflow and discharge states to the outside and the wireless.

An external equipment control unit 280 is provided outside the main body 120 and controls external equipment such as a video camera 282, a weather vane 284 and a thermometer 286 to transmit and receive the external equipment wirelessly.

An operation unit 220 is provided for manually or automatically operating the air vehicle 100 by a user or a program according to information transmitted from the internal and external equipment control units 260 and 280.

The operation unit 220 is provided with a monitor, a manipulation bunch, a joystick, a touch panel or the like to operate the unmanned air vehicle 100 wirelessly.

In addition, it is preferable that the fog detecting unit 240 is further provided to notify a warning to the control center while detecting occurrence and inflow of fog on the runway, and to inform the user of the fog occurrence and inflow to the operation unit.

The operation of the unmanned aerial vehicle according to the present invention will now be described in detail.

As shown in FIG. 3, when fog generation is confirmed by the fog detection unit 240 provided at an airport or a port, notification of a control center priority alert is issued and a warning is given to the user.

The user may manually or automatically operate the operation unit 220 by a user or a preprogrammed program according to an instruction from the control center or an autonomous determination to control the internal equipment control unit (not shown) provided in the main body 120 of the unmanned air vehicle 100 260 and the external equipment control unit 280 are driven.

At this time, the propeller 140 of the main body 120 is rotated to vertically lift and elevate the UAV 100 at a constant height of about 100 m above the ground.

The unmanned aerial vehicle 100, which is vertically taken off, is moved or stopped by referring to the image record, the wind direction, and the temperature collected by the external equipment control unit 280.

At this time, if the rotation angle and the driving position of the propeller 140 are changed as shown in FIG. 1 in the direction to be moved, the movement of the UAV 100 can be accomplished more quickly.

When the unmanned object (100) is kept stationary in a position to eliminate the mist, the upper air is lowered rapidly by the rotation of the propeller (140), and the lower part of the airplane is down by the wind of the propeller Wash occurs.

Therefore, even when the propeller 140 of the unmanned incongruent body 120 rotates as shown in FIG. 2, the mist of a certain concentration can be easily dissipated.

In addition, the jet engine 160 provided at the lower portion of the main body 120 is sprayed in consideration of the user's judgment and concentration of mist.

Preferably, when the jet engine 160 rises to the uppermost level of the mist detected by the sensing unit 240, the propeller 140 is driven in the reverse direction to prevent the unmanned airplane from rising, Change the damping so that exhaust gas and temperature can be discharged from the position. (Harboring function)

At this time, the fog is dried by the discharge heat and the exhaust air stream injected from the jet engine 160, and the mist is agitated due to the descent of the heated air, so that the mist is raindroped and falls down to the ground.

In addition, since the jetting angle and jetting direction of the jet engine 160 are smoothly changed, the fogging range of the mist can be maximized.

Further, since the mist is sucked into the jet engine 160 and is discharged by the jet engine 160, the mist on the unmanned aerial vehicle also rapidly dissipates.

The dissipator 180 provided in the main body 120 of the unmanned aerodrome body 100 is sprayed when the jet engine 160 is sprayed so that the dispersing agent 180 is sprayed downward by the heat and airflow of the jet engine 160. [ Thus, it is possible to easily dissipate fog by coherent fog particles.

Moreover, since the air is heated by the jet engine 160 and is not greatly applied to the external temperature, the dissipating agent can be easily fired without changing the dissipative agent even at a temperature below 0 占 폚.

In addition, the jetting of the jet engine 160 makes it possible for the unmanned aerial vehicle 100 to move and stop more smoothly.

For example, the propeller 140 is driven in one direction, and the unmanned object 100 can be quickly moved in a desired direction by adjusting the jetting direction and the angle of the jet engine 160, Can be adjusted to dissipate a wider range of fog.

In addition, the position of the propeller 140 and the jetting direction and angle of the jet engine 160 are opposed to each other in a stationary state, so that the unmanned air vehicle is easily stopped at a predetermined altitude, It can dissipate.

Even if the snow is piled up or frosted on the runway, the altitude of the unmanned aerial vehicle 100 is lowered so that the downwash by the propeller 140 and the jet engine 160 are sprayed to the runway in the vicinity of the runway, The spraying operation can be easily achieved by the spraying of the runway.

FIGS. 4 to 6 illustrate a second embodiment of the unmanned aerial vehicle according to the present invention, and its configuration and operation are similar to those of the first embodiment of the present invention, so that detailed description thereof will be omitted.
