Abstract

Instant multiextinguisher that is easily transportable and storable, which affords an improvement over the extinguishing features of existing systems, comprising a rounded casing with a handle and a central open passage closed off by a screw cap inside which is housed the explosive charge or bang, the casing having a number of stiffening or protective ribs as well as safety caps and other elements that ensure the device is safe. The extinguishing component inside the container is dispersed in situ at the site of a fire by the actual detonation of the explosive charge or bang, assisted by the shock wave the latter generates in the direction of the fire, said explosion also helping to consume oxygen in the air and thereby suffocating the fire by reducing the combustible oxygen available.

Description

INSTANT MULTIEXTINTOR

Object of the invention

The present invention consists of an "instant multiextintor", within the framework of fire extinguishing systems.

The present invention relates to an instant multiextintor, more versatile, safe and efficient in extinguishing all types of fires. The incorporation of new components, the design of new geometries, application, study and development of closure systems that ensure the sealing, development and homologation of new thunder of less explosive load, along with the discontinuation as dangerous goods (according to standards of UN security) without transport restrictions, come to resolve existing deficiencies.

Background of the invention

The well-known fire extinguishers that are activated by detonation, have numerous limitations, problems of efficiency, handling, storage, safety and costs.

State of the art

The inventor knows some fire extinguishing systems through the use of controlled explosions, but with greater difficulties for transport, assembly and commissioning than the object of the present invention.

Description of the invention. The instant multiextintor of the present invention has been made in order to be easily transportable, storable and provide an improvement of the extinction characteristics of the existing systems to date.

Its configuration is different from all previous designs, and having two embodiments corresponding to two capacities of the extinguisher, although these embodiments are described merely as modalities, not being limiting in terms of their manufacture, which may be in any capacity to contain extinguishing agent, and explosion power.

Advantages;

The advantages of this system in relation to the previous ones are, without limitation, the following:

A) ABARATAMIENTO: Lower manufacturing costs through geometries likely to use blowing methods instead of the injection (higher matrix cost and production), replacing the current Nylon 6/10 product (high economic value) with high polyethylene density (of very affordable cost), a high molecular weight hexene copolymer, type PEHD Lupolen 5261Z (Basell), density 0.954; Met Index 19O ⁰ C 21.6Kg: 2g / 10 min., Especially for extrusion-blowing, especially indicated in the manufacture of containers for chemical products.

B) SECURITY:

1. New approved thunder of low load that allow to reduce the load maintaining the efficiency, from 40 gr., To 8 gr., For extinguishers of 5 Kg., (In which an acoustic protector was recommended); and in the case of 1 Kg extinguishers, from the current 3 gr to 2.5 gr proposed. In both geometries satisfactory results have been obtained.

2. Waterproof cap design. It is a screw cap with thunder housing housing incorporated in the lid, with inner concentric throttling of perfect tightness. The housing of the caps under the protection of the outer edges of the new geometry puts an end to the current problems of losses due to breakage in the mouth of containers (produced by blows). The external threaded design, ends with the losses of the chemical content, when a complete tightness occurs.

3. Incorporation of luminescence. The safety is increased by providing the extinguishers object of the present invention of night visibility using an additive added to the polymer with which it is manufactured. The use of so-called

"intelligent materials" that have the ability to change their physical properties, semiconductor materials (active photo-chromium), through the use of some photo-luminescent additive that has the power to convert absorbed energy into detectable light in the dark by slowly releasing and continuously the photons that cause phosphorescence.

C) SEALING: A new design especially watertight, with sheath for thunder housing and external thread of settlement and fixation.

D) DIVERSITY: Incorporation of specific products for the fight of fires determined by means of specific extinguishing agents for each type of fire, incorporating new chemical products for this purpose, which give the extinguisher greater versatility. So:

1. A sparkling AFFF solution with solvents and salts is used for hydrocarbon fires. lower the crystallization point to -20 ° C (use in cold climates). It achieves very fast extinctions and provides great protection against possible re-ignitions.

2. For multipurpose fire, a solution in H2O is used at 1A FR CROS 134P, density l, 38 ~ l, 40 gr / cm3 concentrates that meet all environmental requirements in effectiveness, corrosion, toxicity, and environmental impact.

3. For electrical fires: dry chemical powder (PQS) that acts as a catalyst inhibiting the combustion reaction, based on mono-ammonium phosphate.

E) ENVIRONMENTAL: susceptible of the alternative use of a biodegradable material in the manufacture of the containers. The new thunder allows to reduce the load maintaining the efficiency, from 40-20 gr., Up to 8 gr., For extinguishers of 5 Kg., (In which an acoustic protector was recommended); and in the case of extinguishers of 1 Kg. from three gr., current to 2.5 gr., proposed with a very satisfactory response. Sound level for artifice of 20 gr.

Extrapolating the results obtained at a distance of 5 m and 1 m, distances at which the device is sometimes exploited and which we take as a reference, values of 74.5 and 75.5 dBC of SEL of 8 h would be obtained. The new proposal expects to obtain, for the distances under study, values well below these marks that reduce the sound impact to acceptable levels.

The optional application of a polymer for the manufacture of the extinguisher container, which has the conventional properties of polyethylene, but is totally biodegradable, in accordance with DIN EN 13432.

F) OPERATION BY ELECTRONIC ELEMENTS: the incorporation of an ignition cable; connections to heat sensors, and remote drive.

G) HIGHER EFFICIENCY: by incorporating an ignition cable that allows the extinguisher to operate without the presence of fire. Break zone control for controlled dispersion. The activation so far was only carried out in the presence of fire, however there are many fires that delay in releasing flame or simply do not release, by means of the actuator connected to a smoke detector by batteries, activation is achieved. A cable without pyrotechnic elements can be used.

H) STABILIZERS FOR HYDROCARBON DEPOSITS: controlled dispersion of extinguishing agents with reinforcements in the appropriate walls, and the incorporation of automatisms, sensors and remote control. Storage and transport, achieving great stacking stability with lace to the effect. The use of differentiated geometries for each utility that allow to adapt to the particular need for which they were conceived.

Preferred embodiment example;

As can be seen in the previous figures, the extinguisher object of the invention seen from the front has the form of a rounded container (1), but it has on one side, and within the body of the container, a grip handle (2) in order to facilitate its handling.

Following the description, we also find that the container has in its upper part an open passage (3) that is closed by means of a screw cap (4) incorporated into an inner cylinder (5) that also It can have a truncated-conical shape and that contains the explosive charge, and in turn, on this screw cap, another safety plug (6) that closes by a clipping system on the screw cap of the cylinder is attached.

Therefore, this step is used to introduce both the chemical extinguishing agent or water, as well as to introduce the hollow cylinder (5), through and central provided between this opening, which is located in the upper part, and the plug located in The lower part (7). As already described, this cylinder which can also have a conical trunk shape, wider in the upper part and narrower in the base, will be used to contain the explosive charge.

The plug located in the lower part (7), smaller in size than the upper one, is used to fix the detonators of the explosive charge contained in the conical trunk-shaped cylinder. Thus, this plug has a hole that serves to pass the wick, cable or antenna that will drive the pyrotechnic charge.

The grooves where the plugs are located have on their sides ribs (8) that confer greater resistance. In the area where the handle is located, as well as in the area opposite to where the handle is located, it also has wide reinforcing ribs

(9). In the area opposite the handle, the ribs form two U-shaped zones, and it is precisely between these two zones that the weakest wall of the extinguisher is located, which is where the entire effort of the explosion will be channeled.

Therefore, the body of the extinguisher is reinforced by all these ribs, as shown in Figure 1, which gives it great resistance and facilitates the addressability of the explosion.

The extinguisher capacity described here is 5 liters, although it can be made in any capacity that needs to be manufactured and used for its manufacture a wide variety of materials, both plastics and any other type.

The safety plug (6) has reinforcing ribs (8 ') on its outer face and on the inner side some lugs (10) that serve as height positioners. It also has a peripheral flange (11) that serves as external clipping. The hollows in the inner channel (12) corresponding to the outer bulges (12 ^' ) have perpendicular to the outer skirt (13) plates (14) that serve as guides for the closure. Internally, arcuate plates (15) protruding from the base are used, which are used in the internal clipping.

In a variant of this embodiment, there are smaller packages, for example of a liter of capacity, in the form of a cylindrical bottle (16) whose external perspective can also correspond to Figure 11.

Inside there is the frustoconical container (5) with an externally threaded mouth (17), with a cover with reinforcement ribs (8 ') and a safety cap (6) equal to those previously described with closing guides (14 ) and height positioners (10) as well as a channel for the wick (18) with detail of inner clipping (19) and outer clipping (20), also has an antϊescapes wall (21).

For the manufacture of the extinguishers object of the present invention, the so-called intelligent materials will be used predominantly that have the ability to change their physical properties, semiconductor materials (active photo-chromium), by using some photo-luminescent additive that has the power to converting the absorbed energy into detectable light in the dark by slowly and continuously releasing the photons that cause the phosphorescence, as well as a high density polyethylene or a high molecular weight hexene copolymer, especially for extrusion-blowing. They will also be provided with night visibility using a photo-luminescent additive added to the polymer, which has the power to convert the absorbed energy into detectable light in the dark by slowly and continuously releasing the photons that cause phosphorescence.

Preferably, these extinguishers will be equipped with a smoke detector (23) powered by batteries equipped with a cable (23 ') that does not contain pyrotechnic elements for greater safety which runs externally the height of the extinguisher, and which can determine the activation of the extinguisher before the activation of the fire occurs. They can also carry automatisms and sensors for remote operation.

The extinguisher will be provided with a clamping means (24) formed by an inverted U-shaped folded plate and attached to the base of the extinguisher in the event that it does not have another handle.
