    [0003] OBJECT OF THE INVENTION
    [0004] The object of the present invention refers to an air transportable device that comprises capsules that disperse an aqueous compound comprising a chemical agent and an element selected from air, gas and a combination of both, the aqueous compound being under pressure in inside the capsules, to fight fires, through the use of explosive force.
    [0006] It finds special application in the field of the forest, maritime and building fire extinguishing industry, from the air.
    [0008] It is also useful for the dispersion of all kinds of liquids or chemical substances on a certain surface that is difficult to access and requires great precision and efficiency.
    [0010] TECHNICAL PROBLEM TO BE SOLVED AND BACKGROUND OF THE INVENTION
    [0011] Currently, the methods of extinguishing aerial fires that exist are very inaccurate when discharging the extinguishing liquid, so a large amount of it is wasted, hours of flight and in many cases time that causes a fire to get out of control For this reason, it is essential that the discharge be as precise as possible, that the liquid is dispersed in the best possible way and that the discharges occur with the greatest possible continuity.
    [0013] Container devices are known to transport water or other extinguishing liquids to fire zones, for example by means of aircraft, and to discharge the water at a certain height over the burned zone. For example, the Spanish utility model with publication number 1018938 describes a tank for liquids applicable to helicopters that has gates in its lower part that open, at a certain height, on the burned area so that the liquid falls on the same. Spanish patent with publication number 252008145 describes a container based on the same principle provided with gates for filling and emptying.
    [0014] For its part, Spanish patent with publication number 8306443, describes a cylindrical tank that hangs from the helicopter and is able to rotate on its transverse axis, dumping the content on the burned area.
    [0016] The aforementioned systems have the drawback that, since the liquid cargo must be released at a certain height to avoid the risk of an accident to the aircraft, said cargo is dispersed and atomized into very small particles long before reaching the ground, losing a large part of its effectiveness. On the other hand, if you try to unload at a low height, the risk of accident increases considerably, especially in areas with difficult access or in adverse weather conditions.
    [0018] The device for extinguishing fires that is the object of the invention includes notable improvements over conventional devices and a very simple and effective solution has been found to face the drawbacks and disadvantages of the devices known in the state of the art described above.
    [0020] Therefore, the present invention solves the aforementioned problems of the state of the art, providing a device that has the following advantages:
    [0022] 1. It is a compact device, highly efficient, easy to use and manufactured in an easy and economical way that, although it is of the explosive type, does not present any serious safety risk when operating.
    [0024] 2. The discharge is very precise, the aqueous compound is efficiently dispersed in all directions.
    [0026] DESCRIPTION OF THE INVENTION
    [0027] The invention refers to a device for extinguishing fires, transportable by air means, understanding as air means any aircraft manned or not, such as airplanes or light aircraft, helicopters, drones, etc., comprising:

    [0093] DETAILED DESCRIPTION
    [0094] The device (1) for extinguishing fires mainly comprises:
    [0096] - an articulated mast (2) that is deployed downwards from inside an aircraft,
    [0097] - a capsule suspension support (8),
    [0098] - some capsules (13) filled with an aqueous compound,
    [0099] - and an actuation mechanism (10).
    [0101] The articulated mast (2) is deployed downwards from inside the aircraft, in the event that it is necessary to add the device (1) for extinguishing fires, so that when the device (1) for extinguishing fires is not required, the articulated mast (2) folds towards the aircraft, being able to carry out its usual operations without the articulated mast (2) posing any obstacle to it.
    [0103] The capsule suspension support (8), which is previously supported by a structure that holds it, is coupled to the aircraft by means of a ring (4) incorporated in the upper part of said capsule suspension support (8) that it is coupled to a hook (3) included in the free end of the articulated mast (2), so that said capsule suspension support (8) is suspended in the air and ready to be used.
    [0105] The capsule suspension support (8) can have different shapes, as shown in Figures 3a and 3b, and can be circular, rectangular, or even other geometric shapes.
    [0107] The capsules (13) are hooked to the suspension support (8) by means of fastening means (5).
    [0109] The actuation mechanism (10) comprises electrical cables (12) and allows the capsules (13) to be released and detached under vacuum at the precise moment when they are required from the aircraft.
    [0111] In figure 3b you can see some cables (12) that are part of the actuation mechanism (10), which reach the holding means (5) of the capsules and the push system (7). cable (12) that hangs from the aircraft parallel to the articulated mast (2) has a quick coupling (11) at its free end which is a mechanism for individually connecting each capsule (13) to the aircraft distributor, in order to control each capsule (13) separately.
    [0113] According to a preferred embodiment, the capsule holding means (5) that couple the capsules (13) to the capsule suspension support (8) comprise electromagnets, capable of creating an extremely uniform and intense magnetic field inside them, and very weak on the outside, which responds to electrical pulses with respect to the release of the capsules (13) to vacuum. The capsules (13) comprise a coupling piece (14) made of biodegradable plastic that allows coupling said capsules (13) to the clamping means (5). Any other mode of clamping means (5) other than by means of electromagnets.
    [0115] The capsule suspension support (8) also comprises a push system (7) of the capsules that is activated by the actuation mechanism (10) simultaneously with the uncoupling of the capsules (13) and separating them when falling, where said system of thrust (7) comprises mechanical actuators.
    [0117] The capsules (13) are single-use and environmentally friendly, leaving little residue other than the chemical extinguishing / fire suppression agents used and comprise:
    [0119] - an outer cover (16) made of biodegradable plastic, with a highly waterproof coating,
    [0121] - an inner cover (18) made of low density, rigid and biodegradable plastic foam,
    [0123] - A filling valve (9) through which the aqueous compound (15) formed by a chemical agent and an element selected from air, gas or a combination of both is introduced, the gas being preferably C02, the aqueous compound (15) being at a pressure of approximately one atmosphere, inside the at least one capsule (13). The chemical agent may be one of those that are commercially available, either dry, wet, or otherwise in single or multi-component combinations, and
    [0124] - a detonation device (6) comprising a pyrotechnic detonator placed in the lower part of the capsule (13) that breaks the capsule (13) and disperses the aqueous compound (15).
    [0126] The detonation device (6) is isolated from the aqueous compound (15) through a protective waterproof envelope (17) and provides a sufficient popping sound to warn people in the immediate vicinity of the threat of fire.
    [0128] The pressure introduced together with the chemical agent helps the explosion to be stronger and the aqueous compound (15) to expand omnidirectionally as far as possible. Both the chemical agent and the element selected between air, gas and a combination of both, can be introduced through the same filling valve (9) or each one through a specific valve. The pressure is approximately 4 atmospheres.
    [0130] According to a preferred embodiment, without excluding other possible configurations of the shell, the outer shell (16) of the capsules (13) is spherical, thus helping a more uniform fragmentation of the capsule (13) with detonation, dispersing in a more effective the aqueous compound (15).
    [0132] The choice of chemical agent (liquid or even gaseous agents) will depend on the particular type of fire hazard providing specialized efficacy.
    [0134] On the other hand, the use of these capsules (13) with terrestrial means of catapult-type drive cannot be ruled out, for use in conditions not suitable for air vehicles, such as night periods or adverse weather conditions.
    [0136] The present invention should not be limited to the embodiment described herein. Other configurations can be made by those skilled in the art in light of the present description. Accordingly, the scope of the invention is defined by the following claims.
