Description

The invention relates to containers for mechanical engineering and instrumentation, in particular to containers for shells of artillery shells, ammunition of small arms, missiles, pyrotechnic devices, as well as other products, during operation and storage of which exposure to open flame and elevated temperatures is possible for a limited time time.

The well-known "Tara" (RF patent for industrial design No. 47172), which consists of a body and a cover connected by locks, through a seal placed in the internal fittings, the side faces of the body and the cover have slopes, the side sections of the body and the cover are trapezoidal shape with combining them with large sides, the ribs and corners of the body and the lid of the container are rounded. On the upper surface of the lid and body of the container, grooves and protrusions are made respectively trapezoidal in section and rectangular in plan, providing grooves and protrusions are combined when stacking, grooves are made in the cross-section and trapezoidal in section to accommodate locks and handles.

A well-known technical solution provides the creation and mass production of containers with the necessary technical characteristics, reliability during transportation and storage, however, it has several disadvantages:

- made of combustible materials (fiberglass based on polyester or epoxy resins);

- does not provide, at a reasonable thickness (up to 10 mm) of the fiberglass shell wall, a sufficient level of thermal protection of the explosive payload in fire conditions (the necessary level of thermal protection should ensure that the maximum temperature of the payload does not exceed 150 ° C for 15 minutes under the conditions of a developed fire);

- It creates great difficulties when using progressive methods of forming fiberglass shells (RTM-molding) in production, since the formation of internal flanges requires the use of composite or flexible punches.

The claimed invention is directed to the creation of containers for fire and explosive objects, which would solve the problems of improving the reliability of protection of products from the damaging factors of fire and the time-limited effects of heat and radiation heat fluxes of various nature: solar heating, radiation exposure of heated objects, light pulse of a nuclear explosion, incendiary mixtures, contact with heated surfaces, etc., protection from external mechanical and climatic influences, provided a rational size ix in vehicles with manual products, storage products in the warehouses, including the open storage and in the field, the convenience of carrying and handling operations while reducing the complexity of its production.

The problem is solved in that the container containing the housing and the lid, forming the outer shell and having stiffeners and grooves on the outer surface, shaped flanges, sealing, locking and other functional elements, further comprises an inner shell, consisting of a similar outer shell of the body and lid connected by locking elements of the outer shell through a seal placed in the groove formed by combining the same elements of the outer and inner shells, while flanging one elements of the inner casing a projection, and the outer surface of the container body and the lid and the inner shell surface facing thereto are coated with intumescent when heated above 150 ° C the composition.

Figure 1 shows the packaging assembly, a longitudinal section,

figure 2 shows a transverse vertical section of the container

The container consists of a housing 1, a cover 2, an inner shell 3, an inner shell 4 cover, a container seal 5. The outer surface of the container and the inner shell surface facing the housing and the lid are covered with an intumescent coating 6 up to 1.5 mm thick. The space between the outer and inner shells can be filled with heat-insulating materials 7 of bulk or fibrous types.

Thus, the goal of the invention is achieved - increasing the stability of containers to the effects of the damaging factors of a developed fire and ensuring an inert state of the payload for the time necessary to eliminate the fire or evacuation of personnel and material assets from the danger zone. In addition, the proposed design of the container provides its resistance to low-power sources of ignition (such as "cigarette butts") and powerful short-pulse sources. The presence of two power shells provides mechanical stability of the container during the fire exposure, which is especially important for collective storage of containers in stacks. At the same time, the intumescent fire-retardant coating 6 with an expansion temperature of about 150 ° C provides favorable conditions for the operation of the inner shell to preserve the mechanical characteristics by attributing the front of the expansion of the coating into the space between the outer and inner shells.

An example of a practical implementation of the invention is described below.

Tara overall dimensions 800 × 500 × 270 mm consists of a body and a lid with a wall thickness of 2.5 ± 0.50 mm, made of low-combustibility polyester fiberglass by RTM molding using fiberglass matrices. The housing and the cover are interconnected via a seal made of porous rubber with locking elements, for example, locks 2-2 GOST 16561-76. Grooves are formed in the housing for placing the handles, as well as protrusions that protect the locking elements from damage when the container falls. On the bottom of the case and on the upper surface of the lid, protrusions and grooves are formed respectively, providing mutual fixation of the same products when stacking. Inside the case and lid, elements (respectively, the case and lid) of the inner shell, also made of RTM-molded fiberglass with a thickness of 2.0 ± 0.50 mm, are placed. The shape of the elements of the inner shell ensures the placement in its grooves of shaped lodgement parts made of chemically vulcanized polyethylene foam grade ППЭ-1П, ППЭ-ЗП, which serve for laying and fixing the property placed in the package, for example, two rounds of 120 mm Nona 3VOF54 artillery guns.

Installation and fixing of the inner shell elements in the housing and the cover are provided by “shelves” 8 on the inner surface of the outer shell elements of the housing and the cover (mechanically) by tightening the elements of the outer and inner shells through the seal (5) of porous rubber. The seal is installed in the groove and tightened by the protrusion 9. If necessary, glue (for example, polyurethane ADV-11-2) or sealant (for example, siloxane VGO-1) can be applied to the surface of the “shelves”, which provides additional sealing of the space between the shells.

On the outer surface of the container, as well as the surfaces of the elements of the inner shell, facing the outer shell, a fireproof coating of the Ograks - V-SK-1 5278-054-1367785-12 type was applied by airless spraying. The cavity between the outer and inner shells of the container can be filled with fibrous (basalt glass wool), foam (polyurethane foam) or bulk insulating materials. The outer surface of the container is additionally painted with XC-5146 or XB-124 enamels, which provide protection against atmospheric influences.

The tare weight is 21 kg;

Payload weight 43 kg.

The proposed packaging can have both a removable lid and a hinged lid, i.e. as described above, detachable and integral loops can be used as locking elements.

Manufactured in accordance with the proposed invention, the container passed the full cycle of operational tests:

- strength under the influence of sinusoidal vibration with a frequency of 15-25 Hz and an acceleration of 2g;

- strength when dropped (on all faces, all edges and all angles) with mass-dimensional models of products from a height of 500 mm;

- on the strength under the influence of multiple impact shocks (1000 strokes) with an acceleration of 15 g.

- on resistance to the effects of fire damaging factors, consisting in determining the temperature on the elements of the payload (temperature should not exceed 150 ° C) when exposed to open flame containers with temperatures up to 800 ° C for 15 minutes

The tests performed showed the compliance of the proposed packaging with the requirements.

Currently, more than 100 items of products are manufactured using fiberglass containers for modern optoelectronic technology. According to its characteristics, the proposed packaging can be used in the design of all these products, providing an increase in their reliability and a decrease in the complexity of production. The high fire-heat-protective characteristics of the proposed containers allow to expand the scope of its application by placing artillery shells, ammunition for small arms, missiles, and pyrotechnic products in it. The use of containers will ensure fire safety of the storage of these products and minimize the effects of fires.

The container in accordance with the invention has an attractive appearance and modern design.

Thus, the present invention provides a solution to an almost important urgent task of increasing reliability and reducing the complexity of manufacturing important engineering products, increasing its consumer and aesthetic characteristics.
