Description of the invention

The explosion extinguisher that has been recommended has been designed to solve the problem described above, in based on new structural features and functionality

More specifically, the extinguisher of the invention is characterized first of all by having a configuration paralilepipédica, in which three of its lateral walls present a thickness and material properties different from the fourth wall lateral, so that the explosion causes the breakage of those three walls and stay without breaking the fourth wall. With these characteristics, the extinguisher must be faced with the focus of fire through the three commented walls, leaving the fourth as a face or back wall, which is equipped with handles of manual grip

The paralilepipédico body of the extinguisher is consisting of two symmetrical halves that are fixed together conveniently, thereby facilitating the manufacture of one's own fire extinguisher, which is affected by a cylindrical and internal passage between both bases, for a cylinder carrying the explosive charge, that is, what is called a pyrotechnic mixing cartridge.

The extinguisher incorporates in its bases a cavity for electrical and / or electronic components that allow activate the explosive charge, either through a wick that light manually or through the fire itself, wick that is initially placed in an area in established depression  perimeter to the cavity referred to above. Also the Explosive charge activation can be carried out electrically by programmable electronic timer, or either electrically using a temperature sensor or even electrically by radio control.

This feature of the fire extinguisher is that both its upper base as its lower base are endowed with four blind holes in correspondence with the corners, to arrange in them some determining axial legs of a support means stable that allows the extinguisher to be placed without coming into contact with the  floor, although it can also be arranged directly on the soil, so that in both cases the extinguisher can remain stably without any problem.

It also includes bars on both bases, for the suspension of the extinguisher, allowing its disposal in any part, that is, hook it to an appropriate support and stay Suspended for use.

Another characteristic of those presented by the extinguisher of the invention, is that the inner part of the edges vertical, that is, where faces or walls converge lateral, are reinforced by nerves throughout the own edges, providing rigidity and resistance to fire extinguisher assembly

Finally, as another feature of novelty, it is expected that both bases of the paralympic body are equipped with two holes for filling the extinguisher itself, filling that will be done through one or another pair of holes corresponding to one and another base, being a hole for the Introduction of the extinguishing liquid product and the other hole for the exit of the air and residual liquid, engaging in said holes paths filling nozzles associated with paths solenoid valves that will close the filling hole and the hole outlet, removing the nozzles from the holes to subsequently these are closed using screws with O-ring, thus achieving a fast filling and without Splashes occur.

Based on the referred characteristics, it they get a plurality of benefits and advantages over other known extinguishers, being able to stand out as more important the following:

-

Due to the paralilepipédica configuration of the extinguisher, this can be stacking with others stably and occupy a minimum volume, both in storage and in transport.

-

In under the characteristics of the side walls, it is achieved a better dispersion of the extinguishing liquid, when the explosion as they break the three walls facing the fire and it keeps the back wall equipped with the handles without breaking.

-

May stand high above the ground and remain stable, under the legs that can be attached over the holes blinds provided in the corners of both bases.

-

To the be constituted by two symmetric halves, you get a cheaper manufacturing.

-

How consequence of the hook bars provided in the bases, the fire extinguisher can be hung from anywhere, by ropes or other appropriate support elements.

-

In base to the two handles that incorporates in its back wall, can handle easily and comfortably.

-

The Explosive charges are easy to install when introduced by the through hole and central planned between both bases of the body paralympic doctor.

-

Possibility of detonating the Explosive charge is done in several ways:

to)

Manually by wick when it It is reached by the fire to extinguish, leaving the wick rolled in the depression or channel determined at the basis of extinguisher.

b)

Electrically by timer Programmable electronic, with two possible functions, one of previous programming after feeding the timer to activate it after a specified time, and a second possibility consisting of pressing a trigger button to start the countdown.

C)

Electrically using a sensor temperature, which upon reaching a temperature previously programmed, a drive circuit is activated and Shooting.

d)

Electrically by radio control, allowing the activation of the extinguisher independently or by Groups according to needs.

-

He fire extinguisher lacks sharp edges and protruding parts, facilitating its application and storage, being resistant to weight and shock moderated, under the reinforcement provided in correspondence with the inside of the edges.

-

It allows to be transported manually from comfortable way and even associated with other extinguishers, in accessories appropriate transport.

The extinguisher described will materialize preferably in Nylon® 6/10, being able to be several applications or uses, resulting in high efficiency as a fire extinguisher forestry, either in direct attack in order to cut off the front of the fire, either in indirect attack forming barriers or defense lines by arranging several fire extinguishers, with In order to isolate the fire.

It can also be used in extinguishing hydrocarbon fires, since the oxygen deficit that produced by the explosion, together with the dispersed chemical, facilitates the elimination of llamas.

He also admits to being equipped with means for his remote controlled detonation, which would allow new uses of the extinguisher, among which the detonation of anti-personnel mines.
