DESCRIPTIVE MEMORY

MODULAR BOXED CAMERA FOR EXPLOSIVE STORAGE

Object of the Invention

The present invention relates to a modular vault for the storage of explosive products, which provides essential novelty characteristics and notable advantages over known means and used for similar purposes in the current state of the art.

More specifically, the invention proposes the development of a vault for use with materials of the type mentioned. Which has the peculiarity of being mobile, after Lazab Le, with the use of adequate means of transport, being built with the use of materials and following an operation capable of guaranteeing an increased safety of the product locked inside, and having also provided means that ensure at the same time an adequate ventilation of the interior space, in order to eliminate the internal accumulation of gases or the entry of foreign matter from the outside that could damage, in some sense, the explosive contained inside the chamber. The ventilation means have also been designed so as to prevent the accidental or intentional introduction of any object or material from the outside.

The field of application of the invention is comprised within the industry dedicated to the manufacture of security containers, and more particularly of armored chambers.

Background and Summary of the Invention It is known that with a certain frequency it is necessary to transport explosive material from one place to another, and it must finally be stored at the destination. Obviously, the handling and transport of this type of materials requires the adoption of a series of precautions that must prevent the fact that the explosive material is damaged as a result of such manipulation, or even that for any circumstance, some foreign person could have improper access to it. These requirements require that the explosive material be treated properly, both from the point of view of safety in handling, and from the point of view of the precautions to be taken to prevent it from being subtracted or from being available to other people. outside the caregivers.

Taking into account the previous precepts, the present invention has proposed as a main objective the fact of providing a system by which it can be ensured, in an effective way, that all the requirements and norms that revolve around this type of materials are met. .

This objective has been fully achieved by means of the vault of the present invention, which will be the object of detailed description in the following, and by means of which a housing is provided delimited by side, ceiling and floor walls that are formed by various layers made of metallic materials, refractories and composites that guarantee the obtaining of an armored and fire-retardant block, which presents a great structural resistance against its attack with combined tools, and that therefore is qualified for use with explosives. The panels, which in their design are tongue and groove, are fixed together by welding continues extended to the entire length of the respective joints. In addition, the camera has a predetermined number of lateral, lower aerations, conceived as anti-intrusion, that is, carried out in such a way as to prevent the introduction, accidentally or intentionally, of both objects and the hand of an external person, or of Any other instrument or tool. Likewise, the chamber also has upper vents, which in combination with the lower ones establish an air flow to advantageously keep the inside of the chamber vented, and whose access is also protected against foreign elements with the collaboration of means that, by way of caps, cover the entrances.

Finally, the camera also has means that adapted to the lower part and to the sides of the contour thereof, constitute support skates and have holes to facilitate its grip and lifting with the means and devices appropriate to its weight.

Description of the Preferred Embodiment

As indicated above, the detailed description of the preferred embodiment of the invention will be carried out taking as. base the representations of the attached drawings, through which the same numerical references are used to indicate equal or similar parts. Thus, with reference to Figures 1 to 3, various views can be seen in front, elevation, rear and side elevation views, respectively, of the vault built according to the invention, and indicated in general with the numerical reference 1. Such and as can be seen, the preferred configuration that has been adopted for said camera corresponds to that of a prismatic compartment, of rectangular base, although obviously other shapes are also possible. The chamber is provided with a front door 2, constructed in accordance with the various safety standards required for this type of products, and through which you can access the interior space destined to contain and store explosive materials, said door being equipped of the closing / opening means necessary for its correct and safe operation depending on the application to which it is intended. As can be seen in the elevation views of both Figures 1 and 2, the body of the chamber 1 has on its side and lower sides, means 3 in solidarity with the body of the chamber, to allow the manipulation and lifting of the same with the right lifting devices. Said means have materialized as metal elements spaced apart from each other, projected orthogonally outwards, and properly attached to the surface of the chamber. This arrangement can best be seen in Figure 4 of the drawings, in which four elements 3 appear on each side, although the number thereof may be variable. Logically, the holes 4 of the different metallic elements 3 occupy equivalent positions, so that they are advantageously aligned.

The invention has provided the armored chamber with aeration means both in its lower and upper part. The lower aeration means are clearly represented in Figures 1 to 3, having generally been indicated with the numerical reference 5. According to the preferred embodiment, the larger faces of the chamber show two inputs for the aeration system (whose configuration is it will be described later with respect to Figure 6), while the smaller side faces show a single inlet for said aeration means. Again, this arrangement is illustrative only, since the distribution of accesses for air intake could be any other depending on each particular need.

As for the air outlet accesses provided in the upper part, they have also been represented in Figure 4, materialized as holes 6 of appropriate configuration, while in Figures 1 to 3 the protectors 7 are shown schematically. each of such holes 6 has been provided, avoiding that foreign bodies may be introduced from the outside in a casual or provoked manner, and whose constitution will be explained later with reference to Figure 5.

According to the foregoing, a highly resistant armored chamber is provided and with increased protection characteristics of the explosive product contained inside. As a guarantee of this protection against any external attack, its construction is carried out based on wall, floor and ceiling panels obtained by superimposing different layers of metallic materials, refractories and aquarium refining composites. The result of all this is an armored and fire-retardant panel, which shows great resistance against the attack of combined tools, and therefore ensures the best possible protection for the explosive. The panels are configured with conventional tongue and groove, so that they then support each other through the application of welding along all the respective joints.

As an additional safety feature, the invention has provided that the inner surface of the chamber body 1 is covered, in its entirety, with fire retardant wood, of any of the appropriate types that are known and available in the market, for the purpose of properly hiding all metal parts, in the avoidance of any unwanted rubbing or bump, under certain circumstances, could lead to explosive deflagration.

If reference is now made to Figure 5 of the drawings, a vertically sectioned view of an aeration hole of those provided in the upper part of the vault can be seen therein. According to this representation, it is observed how the hole 6 it crosses the thickness of the upper base 8 of the chamber, and ends superiorly in a raised mouth portion somewhat above the surface plane of said panel. Surrounding this mouth, is the protective cap element 7, which is fixed, preferably by welding, to the surface of said base 8, with the use of three or more legs 9, while inside it shows a projection 10 cylindrical, concentric, approximately centered with respect to the raised mouth portion. This arrangement constitutes an anti-intrusion access, since it provides sufficient space for air circulation without any difficulty, and yet does not allow it to be used by any stranger for the introduction of Lndeseados objects.

On the other hand, in Figure 5 there is also an indicative representation of the way of anchoring and fixing the chamber in a desired place. For this, the lower panel 11 pieces 12, preferably four pieces in predefined positions, which provide respective through holes 13, widened at the top, for the use of bolts for fixing to the ground or other support surface, with housing of the head of the respective bolt in each widening of the associated hole 13, so that said head can be hidden with the use of complementary parts (not shown) that coupled to the top of such widenings, suppose a superficial continuity of the internal face of the panel 11, without sharp edges or other undesired inequalities.

Finally, with reference to Figure 6, it is also shown schematically, in cross section, the lower aeration system of the armored chamber and which, together with the upper holes 6, allows it to be • establish an air flow that prevents unwanted accumulation of gases inside the chamber, keeping the interior space perfectly ventilated. This system also constitutes an anti-intrusion embodiment, and it has materialized on the basis of laminated panels, superimposed in parallel, successively separated from each other by a predetermined distance, in each of which a plurality of through holes 15 have been made. you can see, these holes occupy positions displaced in successive panels, so that the holes corresponding to two adjacent panels are never faced. In this way, the possibility of intentional introduction of objects from the outside is avoided, as well as the accidental entry of water or other materials that could negatively affect the explosive contained inside the chamber. In this way, the storage of the explosive product is guaranteed under optimal maintenance conditions.

The invention provides a vault for the storage of explosives whose construction is carried out with materials that provide increased fire resistance characteristics, for example in the face of a fire, the aeration holes and the door being protected with intumescent products. In accordance with the practical experiments to which the armored chamber of the invention has been subjected, the external wall of the exposed chamber was maintained at a temperature of 600 QC for a time of 2 hours, without at any time being exceeded in the Inside the chamber a temperature of 50 QC. Taking into account the type of materials that will normally be contained inside, this circumstance guarantees the integrity of the stored material, and that it will not suffer any alteration in case, accidentally, the camera was subjected to unwanted effects of a fire for a period of time such as that which has been • mentioned, and that would obviously be sufficient for the intervention of security personnel.

It is not considered necessary to make the contents of this description more extensive so that a person skilled in the art can understand its scope and the advantages derived from the invention, as well as develop and implement the object thereof.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so that it may be susceptible to modifications without implying any alteration of the basis of said invention, such modifications may affect the form, the size and / or manufacturing materials.
