Description

Explosive fire extinguishing bag.

Object of the invention

The present specification refers to a Invention patent, relating to an explosive extinguishing bag of fires from the air, by transport and launch from all types of aircraft, (helicopters, airplanes). This bag allows disperse water or liquid for extinguishing forest fires, or other uses, on a certain surface, in a way comfortable, safe, accurate and effective, in extreme conditions, in that you have difficulty approaching it, because of its topography, for being at night, with turbulence, etc.

Said bag may have different sizes and forms, having inside (in the center of inertia) a explosive, which can also have different intensities, to disperse water or extinguishing liquid in different ways, to Different types of fires or other uses.

It is an invention that does not intend to replace the already existing if not complement them. This bag has been designed so that its production is very cheap and of a single use regardless of as much of another problem as its maintenance.

Field of the Invention

This invention has its application within the forest firefighting, marine and firefighting industry buildings, from the air.

It also has its usefulness for the dispersion of all kinds of liquids or chemicals on a given surface to which it is difficult to access it and Need great precision and efficiency.

Background of the invention

There are currently several patents referred to different ways or systems to undertake the extinction of a fire or disperse liquid similar to this patent, among them are:

- The system of " fire fighting cubes " also called "slung buckets", containers permanently anchored to helicopters, which spill the fire extinguishing liquid inside the cube when they are at a very close height and situation of the fire that you want to extinguish. This system has several problems, among them, the need to get very close to the area of fire that you want to extinguish, with the danger that this entails, since if it were not so the liquid deviates or evaporates before reaching extinguish or wet the required area.

Since this "fighting cube fires "from a helicopter, it is limited to spilling the liquid a short distance from the ground without properly dispersing it, it is estimated that only 5 to 10% of the water that is discharged is effective, the rest, or it evaporates or falls into another place that is not necessary. Another of the problems are in the possibility of tripping over high cables or low voltage, telephone cables or other obstacles that above all at night they are very difficult to see or detect.

Because of the danger of the approach to the ground in these missions of a helicopter or plane, in hours that there is no sunlight, these devices or these systems are not used in those night hours, having to do without one of the systems more effective for firefighting.

The need to get very close to the fire that you want to extinguish also has the problem of generating turbulence due to helicopter rotors, having to move away from the fire brigade 15 to 20 meters from the area of approximation of the device, due to the danger involved, having to stop your work until the helicopter moves away.

There are many patents for this system, for example, US 6,125,942 A, US 3,710,868 A, US 4,474,245 A, WO 9,423,797 A, WO 9,428,975 A, etc., which differ in mechanism that is used to fill and empty the bucket and some more detail. These cubes are only released in case of danger to the crew for the instability of the aircraft and in case of doing so the cube would be broken with the consequent economic cost and danger Which means its fall.

- Firefighting planes . Based on discharging water or fire extinguishing liquid from an airplane. These devices are prepared to load water from lakes, water dams or large rivers, flying over its surface and subsequently discharged when passing over the fire zone that is to be extinguished.

These planes also have similar problems than the previous system since they have the need to approach the ground or fire zone for the discharge of the extinguishing liquid of fires be as effective as possible with the consequent danger for the crew and ground staff. And the water recharge in the plane is dangerous at the moment of dragging its gut over water

The aircraft used in these two procedures are of relatively small size, due to the need to approach the fire, so they need to have a lot maneuverability or agility in flight. For this they also have of high power engines with the consequent consumption of fuel.

Currently the methods of extinction of air fires that exist, which are the ones that are most used for their supposed effectiveness, they are very little accurate when downloading the extinguishing liquid, so a lot of the waste is wasted same, flight hours and on many occasions time that makes uncontrol a fire, so it is essential that the discharge be as accurately as possible, that the liquid is dispersed from the best way and that the downloads occur with the greatest continuity possible.

- Hand pumps , based on the idea of small-sized containers, with the possibility of transporting single-person units without special physical qualities and can be used or launched manually without much effort. These pumps for their size, for better efficiency, are designed so that their fundamental component of fire extinguishing is a chemical, dust or gas, which are highly harmful from an ecological point of view and dangerous for the person using it , for its toxicity.

- Projectile or missile bombs , which are very formally similar, and sometimes also in the way they work, to war bombs. These pumps are expensive in their production and complex in their handling, also having the disadvantage that they normally use as an extinguishing agent a gas such as carbon dioxide, or chemical dust, which is ecologically harmful and highly toxic to firefighting crews. They also have the problem that their construction is of hard and heavy materials that when exploding and falling on the fire zone can be dangerous for people.

- There are other patents similar to the proposal that, or spill the extinguishing liquid without expanding it, or are small in size and expensive to produce, or if they have explosives, inside they do not have water or extinguishing liquid, but chemical contaminant dust or Gas such as carbonic anhydride becoming very toxic and therefore have the same problem as the previous ones.

Description of the invention

The invention patent that the present report proposes, consists of a plastic bag or similar, which is filled with water or fire extinguishing liquid or other substance and inside it has an explosive that is operated with a detonator by a remote control or remote control, or, in a way automatic, using an instrument that depends on an altimeter. its operation or way of use is that once filled the liquid bag is dropped from an airplane or a helicopter to a comfortable and / or non-dangerous height, on a surface, becoming explode precisely to the desired height.

The bag (1) is made of a plastic material and biodegradable. When you don't have any liquid inside, you have very little weight and volume (similar to an inflatable beach ball), having the advantage of being able to transport a large number of them in little space. You can enter contents in the bag different (non-toxic) to, for example, lower the temperature of the Air or other purposes. The special design of the patent makes it not necessary any type of tool for its handling, it is a single use, therefore, lacks maintenance and is cheaper than existing patents.

The bag has three elastic straps positioning (5) to place the explosion device in the center of inertia of it.

Inside it contains a Device of explosion (2) which is composed of a tightly closed box which inside contains a transmitter detonator, and for a explosive, which may be dynamite or the like; or, a bottle of air compressed or other type of gas, which activates the detonator produce a gas or compressed air expansion sufficiently large enough to create the same effect as dynamite, with water or liquid inside the bag. The explosives used can have different intensities and ways to expand, to disperse the liquid in different ways depending on what is intended, for example the possibility of spilling the liquid very concentrated almost without spreading it, or on the contrary, dispersing it forming a very fine rain that when vaporized lowers the temperature of the top layer air, all depending on the need for Every fire or mission. There is also the possibility of leaving the bag explodes against the ground or at a distance of centimeters of it to cause a certain effect.

The explosive bag has on its top the mouthpiece (3) for filling liquid from the bag and the drive and remote control device (4), consisting of a power switch (4-1), the system GPS positioning, the transmitter that orders the detonator and a second safety switch (4-2), a guide (7) and its guide cap (6).

This drive and control device remote (4) is what activates the explosion device (2) through of a control remote control (10) or automatically by an altimeter or other system.

The safety switch (4-2) causes the transmitter, which is the one that orders the detonation of the explosion device (2) to be activated only at the moment when the bag of the aircraft that transports it is dropped or dropped.
ta.

In the drive device (4) find the guidance guide (7), which is used to maintain vertically the bag but drops it freely. This guide, before deploying, it is protected under a hood (6), that is released or uncovered letting the guide unfold to it time that the safety switch (4-2), with the cable (8), which is attached to the aircraft by means of the mooring ring (9).

The present invention allows the possibility of use the army's potential in the use of bases military and its large number of aircraft and personnel, for the firefighting and other purposes that may be necessary use, for example insect pests, etc. With this patent Different strategies can be followed, depending on the type of fire that you want to extinguish. Starting from the base of which They can drop many bags at once. For example, you can blow up water bags at different heights to cool the different layers of air and at the same time explode others in the own fire making the action more effective.

A fundamental quality is that the download is as accurate as possible within very safe margins superior to those that exist today, and that these downloads can occur with the greatest continuity over time and in the space.

If you use the army bases with your potential in men and cargo planes, you can ride a device capable of dispersing water or extinguishing liquid or another substance over a given area with an efficiency and absolute record as you could have the number of aircraft enough for while some are dropping bags on the mission zone, some return from the mission, others third parties are loading new bags at the base, and a quarter They are on their way to the mission.

Preferred Embodiment of the Invention

The particularly preferred embodiment of the Non-limiting invention will be:

The explosive fire extinguishing bag that The present invention proposes, presents a container or bag (1) elastic and biodegradable, having inside the Device Explosion (2) communicated with the Drive Device and remote control (4) which in turn communicates with the remote control control (10), to be detonated in a timely or desired time when the safety switch (4-2) what It allows.

The design of the invention is made so that it is not necessary to use any type of tool for your driving.

The explosive fire extinguishing bag is Design to be used only once. Because of this the bag Elastic (1) is of a highly biodegradable material, with a sufficient quality to support the liquid inside and keep your qualities intact for a few hours, time that it would take from filling to exploding in the desired site, and once used, degrades or decomposes rapidly after getting wet inside it.

Said bag (1), before use, when It has no liquid inside, it has very little weight and volume (similar to a beach ball), having the advantage of be able to transport a large number of them in a small space.

The bag is a single layer of material having a special design to disintegrate in a way determined at the time of the explosion, and to preserve a certain form once filled. It also has a reinforcement in the bottom of it for chafing with the ground in the moment of manipulation

This patent proposes bags of different sizes and shapes, and the guidance guide does not have to always be on top of it, to disperse the extinguishing liquid in different ways for different types of fires and needs. These bags can be a lot of sizes larger than those used by the rest of the patents existing with the advantage that this implies, taking into account the possibility of transporting them in large aircraft.

The explosive fire extinguishing bag it has, approximately in its center the explosion device (2), which is tucked into a small box tightly sealed so that no liquid enters and for safety reasons, preventing its opening and manipulation without breaking it.

The explosion device (2) is kept in the center of the bag using the elastic straps of positioning (5).

The explosion device (2) is formed of two parts, for a detonator, and for an explosive, which can be, dynamite or similar, or, a bottle of compressed air or other type of gas, which, when activating the detonator, causes an expansion of the gas or compressed air, large enough to create the same effect as dynamite, with water or liquid inside the bag.

The detonator is communicated with the Device Remote Control (4) through which you receive the command of the Command to Control distance (10).

The explosion device (2) can have different sizes or explosion intensities for different types of bags or ways to expand water or liquid.

On the outside of the box, on a plate, the type of explosion device is clearly described (2) for the type of fire and type of bag for which it is configured. This same description is placed on the surface external of the bag, placed in an easily visible area both folded as full of liquid.

On top of the bag along with the drive and remote control device (4), is the filling mouth of the bag (3) with its automatic cap.

       \ newpage
    

The Remote Control and Drive Device (4), as stated above is placed on the top of the bag, also for safety reasons, inside a box tightly closed. This device has different functions. A switch start or on (4-1), a system of positioning of the type "GPS" or similar, a system of Receipt of the command of the remote control (10) of Detonation of the explosion device (2) and a second switch safety (4-2).

The power switch (4-1), visibly placed with a lid transparent so that it cannot be operated accidentally and its function is to start system operation, turning on intermittently a green leed. On the one hand, this power switch (4-1) puts on operating a "GPS" or similar, which emits a signal from positioning, which communicates to the remote control (10), controlling this your exact situation to the one found in everything moment (both geographical and its height). On the other hand, leave it powered the Safety Switch (4-2).

The power switch (4-1) is activated when the bag (1) is filled with fire extinguishing liquid or other substance, and prepared in the aircraft to be used. While it is not activated said Switch, the bag can not explode in any way. Y Finally, the receiver of the signal emitting the Control remote control (10) to operate the detonator of the Explosion device (2), to be operated by the Power Switch Security (4-2), which is detailed below.

This Drive or Control Device Remote (4), can be replaced by an automatic system of Detonator activation by an altimeter, adjusting the height to which we want the explosion device to detonate (2).

The Safety Switch (4-2) that has been mentioned, once the Power switch (4-1), makes while not the aircraft bag is dropped, the explosive cannot be detonate in any way.

The moment you drop the bag from the aircraft, part of the safety switch (4-2) it is broken by pulling the bag itself tied by the cable (8) and the ring (9) to the aircraft, and the Remote Control Device (4) is activated and is ready to be detonated by the Command to control distance (10). The safety switch design (4-2) is designed so that it can only be operated when a piece is broken by pulling hard, making it impossible that is done differently unless it is intentionally.

If the power switch (4-1) does not work, even if the device is broken security (4-2) in any way, you can't actuate the explosion device detonator (2).

The remote control (10) has three functions, receiver, transmitter, in communication with the Device Remote control (4) of each bag and a control system.

one/

By On the one hand, it receives from the "GPS" of the different bags, the exact position of each of them and if they are ready to be detonated

2/

By on the other hand, it emits at the precise moment to the Device of overcrowding and remote control (4), the explosion order of the bag.

3/

By last the control system, which is the one that handles all this information, issuance, reception and execution, and is done through a "computer", watching on your screen with a specific program, on a topographic map of the area, the bags that are in the air, at the exact height and position of each of the bags in every moment, and make them explode at the right time.

Once the bag is in the air, it remains suspended from an Orientation Guide (7), keeping the bag with a vertical orientation but dropping it freely. This is because the bags explode in a certain way and its good orientation causes the liquid to disperse in the most suitable way. Although as with the Remote Control Device (4), there are bags in which, by the way of dispersing the liquid, you can dispense with this guidance guide.

Since more than one bag can be downloaded at same time, the system is designed so that at the moment that the Power Switch (4-1) is activated, it will activate the "GPS" and the "control system" of the Remote Control control distance (10) distinguishes one bag from another by different codes, and the person responsible for the remote control detonates a another at a precise or convenient time.

Any type of aircraft can be used. If the usual helicopters are used for the traditional ones "fire fighting cubes" also called "slung buckets ", its operation would be similar, hanging a sack with an opening system to drop the explosive bag of your inside. In this case, more than one bag can be hung under the helicopter, as long as the size of the bags and their weight allow. This sack or sacks does not have to hang excessively by the bottom of the helicopter, so it makes it more stable statically and aerodynamically with air speeds of 120 km / h and in conditions of high turbulence.

You can also use large helicopters size capable of displacing a lot of cargo, such as those intended for transport containers or those for troop transport military as the CH-47 CHINOOK.

You can also use cargo planes from any size, such as the HERCULES, the C-212 AVIOCAR, the AIRBUS A400M or even the big ones like the C-17 GLOBEMASTER III or the C-5 GALAXY.

For all this to work on airplanes and cargo helicopters, a conveyor belt is installed in the inside the aircraft and others abroad. On the tapes of outside, the bags are filled with liquid and once prepared, they they slide inside the aircraft also using the tapes conveyors inside them. Once loaded the aircraft, interior conveyor belts are used to throw the bags from the cargo hold at the exact moment wish.
