Description

INFRARED SAFETY SYSTEM TO AVOID ICE FORMATION AND SNOW ACCUMULATION ON LANDING TRACKS.

The present invention relates to a safety system, which, using infrared radiation, heats the surfaces in tracks of

take off or landing, so that these are never covered with ice or

snow, thus avoiding the dangers of traveling with a plane on a surface in these conditions. During the winter months, and especially in areas of

10 mountain, it is usual to find the airstrips, where they have to

circulate airplanes, covered with ice or snow. These situations

they carry a lot of danger, since the airplane loses grip and

traction. For example, the braking distance, which varies by state

of the road, in case of snow or ice on it, it can be up to 10

15 times higher In addition, the presence of ice or snow on the airport runway is reason enough to temporarily close and disable that runway, due to the danger involved,

causing great delays in both departures and arrivals in

days of temporary, and even causing the total closure of the airport in 20 extreme cases.

The present invention has its industrial application in the sector of

security devices and systems in airports and in general in

all kinds of roads where any means of transport circulates.

Various inventions to eliminate ice are currently known.

or snow of this type of paved surfaces. Patent CN101285292 describes a system for removing snow and ice from roads and airports by means of solar and / or wind energy. The invention

5 described in this document can convert solar energy and energy

of wind into electrical energy and converting said electrical energy into thermal energy that is stored underground, thus ensuring that the road surface in the winter is kept at a temperature

adequate and that the snow on the road surface melts and is discharged into a roadside ditch. It will be chosen among a

photovoltaic system and / or according to local wind and sun resources. The

CN201169736 patent describes a system of pipes buried under the surface of the road or runway, through which steam circulates from

high pressure water, achieved by a boiler. The patent

CN101280554 describes a method of melting ice and snow in the

road surface. To carry out. an induction coil

is placed below the road surface, this coil is

connected to a current generator with a power supply. By

below the road surface, the magnetic flux generated by the

20 induction coil is penetrated through the conductive material of the road surface, so that the temperature of the material

driver rises to melt ice and snow on the surface of the

highway.

All this that is known presents solutions to problems

generated by snow and ice on roads and airports, either

by air or hot water, electronic systems, etc. most of

These systems are installed underground, under the desired surface

necessary to deconstruct and rebuild the roadway, which implies

Therefore, the invention proposed here presents the

following advantages:

1 Does not allow snow to accumulate or ice to form throughout the

surface covering.

2 It is located at ground level, without support posts,

so you can get as close as possible to the area of

infrared performance. 3 It is not necessary to do large works for installation, nor

lift the road, as it is located on the sides of it, which

Provides economic and time savings.

5 4 Since it is infrared radiation, it only heats the

surface to which it is projected, not air, or adjacent surfaces, with the consequent energy savings.

S You can have humidity and temperature sensors, so that the rays begin to project before the formation of ice or the accumulation of snow begins. 6 In addition, the accumulated water will evaporate faster than usual conditions, due to the same heat.

Thus, the present invention is composed of one or several infrared radiation devices, similar to those used as stoves for 15 terraces. These devices emit infrared radiation at the appropriate frequency to melt snow or ice on the surface to which they are projected. This system is installed at ground level to one or both

sides of the track that you want to protect from snow or ice, so

that covers the entire surface to be protected from it with its radiation. In this way, this system can be used on roads or highways that run through mountain passes, airstrips, streets, or

garage ramps, for example. To cover all the land, they can

use several units of the same system.

The system incorporates a switch which cuts or connects the

electricity supply manually for shutdown and / or commissioning. You can also carry an on and off system

automatic that works by means of sensors of humidity and 5 temperature and that activates the device before it begins to accumulate snow or to form ice.

It also carries an electronic security system that cuts off the electric / fuel supply (gas, diesel, etc.) automatically in

if the system were to shut down (either due to electrical failure or

10 other type) or will detect leakage or malfunction of the device. At

If it runs on fuel, this shut-off valve is

below the surface of the earth. The system also shuts down.

automatically when electrical failures or connection errors occur

of cables. 15 The system incorporates a protective cover that insulates it from

inclement weather. This cover also has an area of

deformation or folding programmed ensuring that the crash of any vehicle causes it to close / sink. If this happens, the electronic security system is started with the consequent shutdown and shutdown of fuel / electricity supply. This cover can have integrated access to the interior through a window that is disassembled for maintenance, review and / or replacement of

components. You can also wear a metal mesh around the

cover to protect your interior from foreign bodies.
