Abstract

Extinguishing housing # This invention is composed of a housing (FIGURE 4) or cylindrical shaped container in the center and oval at the ends. This container will preferably be made of PVC or other plastic material, biodegradable and flame retardant. # The housing will be filled with materials such as extinguishing powder, retardant, foaming with water, gas, etc. It will also carry seeds for restocking such as pine nuts, acorns, chestnuts, etc. # They will be used to launch from one or several shuttles from which a large number of these housings will preferably be driven at a great distance, between 400 and 800 m, with the objective to extinguish forest fires, reducing the risk for the different operators by not having the need to be close to the fire, working with tranquility and precision.

Description

DESCRIPTION

Fire extinguishing housing

SECTOR OF THE TECHNIQUE

The present invention (FIGURE 4) refers to a housing, filled with extinguishing powder or other components, intended to be applied in fires and others by firing with a pyrotechnic shuttle (FIGURE 2).

STATE OF THE TECHNIQUE

The current means of extinction are sometimes not enough in the fight against fires, since due to various issues such as difficult access, adverse weather conditions or the inability of air means to arrive at night, they prevent effective action on the fires, growing these without control and even becoming uncontrollable as happened last summer of 2012 in La Gomera, in which the fog prevented the air media from exercising their function and the fire spread uncontrollably until reaching the park of Garajonay. fifteen

But even more important is the risk that operators responsible for extinguishing fires that must face the flames, either through land or air vehicles at low altitude, face.

In recent years the fires have caused numerous losses, both in ecosystem, reducing a large number of hectares of forests and even protected areas and in 20 personal injuries, with loss of life in many cases as evidenced by recent events.

These fires are mostly caused, so they are usually carried out in hard-to-reach areas and at dusk, preventing rapid action and increasing the danger of this action. 25

DETAILED DESCRIPTION

The objectives of the fire extinguishing casing are: to be able to act in areas of difficult access for the rest of the fire extinguishing means and reduce the risk, in a very high percentage, that the fires currently present for the personnel destined for their extinction avoiding the need that they approach the burned areas as well as being operational 24 hours a day to stop the fires in the beginning, preventing their spread and uncontrolled significantly.

The extinguishing shell is composed of a cylindrical body or container in the center and oval at the ends. Machimbrado and glued at the joints of the body with oval ends for easy loading. This container will preferably be made of PVC or other plastic material, although it is also possible to manufacture its culottes in nylon and the reinforced cardboard body being biodegradable and flame retardant materials, if possible.

Inside there is a normal or retarding extinguishing powder. It will also be necessary to manufacture two powder mixtures: the elevation powder composed of potassium nitrate, charcoal

and micromised sulfur, and the deflagration powder composed of potassium perchlorate and matte powder aluminum. It will also have a fuze with electronic security initiate for its initiation.

They are intended to be used as elements that can be thrown towards the flames or others, from a series of shuttles arranged in a trailer or truck that will be operated through 5 electronic equipment that will allow you to choose between different modes of "firing" of the housings, driving the different shuttles in order that the housings reach the objective of the most suitable form and with the maximum effectiveness.

The process of using the housings would be as follows:

After the placement and connection of the housings with the corresponding electronic device, 10 which will be responsible for sequencing the different "shots", and after the orientation of the shuttles, the housings are launched through the corresponding orders commanded by a microcomputer. The gunpowder will be responsible for its launch up to a distance of between 400 and 800 m. The deflagration that occurs upon reaching the flames displaces the air necessary for combustion and then triggers 15 that allows the extinguishing powder stored inside it to spread over a wide area of the fire proceeding to its extinction. When launching from a suitable platform arranged with a large number of shuttles with several of these housings, ample fire surfaces can be extinguished, remaining at a very safe distance.

These characteristics give the extinction housings a series of advantages that make them an effective method of support for existing extinction methods or even in some cases it can replace traditional methods, being able to act at night or with adverse conditions, in the face of the inability of the air means to act in these conditions, at great distances without the need to approach the burned areas as fire trucks, air means, etc. need. In addition to having the capacity to act at a distance, it will avoid the risk that it entails for the operators to approach fires by being able to act from roads and rural roads, positioning themselves in safe areas and without the nervousness of being in danger.

This innovative invention not only serves to extinguish fires, another important advantage of these housings is the possibility of being used to create firewalls and prevent the burning area from being extended or uncontrolled, for this reason it can be filled with retarding and / or foaming agent and launch over the area that is intended to create the firewall, spraying it with said retarder in the quantities that were necessary.

The possibility of causing unwanted damage is virtually nil, since all its components are soft. In addition, when detonated, spray the surroundings with extinguishing powder 35 (90% potassium, that is, fertilizer, beneficial for the field). It even has several safety measures so that the housings can only be detonated when desired: through the flames of the fire itself or remotely through the corresponding electronic system. The electronic devices (firing table) used have security keys that prevent both its operation and its accidental launch. 40

It is also intended to incorporate different seeds inside the shell such as pine nuts, acorns, chestnuts, etc. that can contribute to repopulate the area on which the carcass has acted, thus beginning the reforestation of the devastated area at the same time.

FIGURE 1 represents the sectioned extinguishing shell, where the different Chambers are listed: lifting chamber (1), transport chamber (2) and deflagration chamber (3). 5

The pyrotechnic shuttles mentioned are represented in FIGURE 2.

In FIGURE 3 you can see the launch of several housings towards the fire started in a steep terrain from a platform arranged with several shuttles. You can also observe the trajectories of several of these housings, as well as the release of the extinguishing powder from the housings that reach their objective, finally extinguishing the flames. 10

A three-dimensional model of the extinguishing shell is shown in FIGURE 4.

Other possible uses, for which this invention is intended and that can be given to the housing, will depend on the component that it carries inside, for example, it can be used as a prevention element so that it is filled with herbicide and through The shuttles launch and spray the areas you want to protect as well as to fight against 15 pests and diseases of groves, plantations, etc.
