Description

The utility model relates to the field of safety during transportation and liquidation of explosive devices, which may include highly toxic substances, and can be used in the manufacture of mobile means of transportation and liquidation of explosive devices.

The closest in technical essence and the achieved result is a portable explosion-proof chamber containing a metal spherical body with an entrance to the internal cavity in the form of a neck with a lid and a shock-absorbing element in the form of a hollow cylinder, inside of which an explosive device is placed.

(JP 5045100 A, F42D 5/04; F42D 5/0, published 02/23/1993)

However, the known explosion-proof chamber, which is carried manually, is not intended to repeatedly detonate an explosive device of sufficiently high power. In addition, the lightweight cover design cannot ensure the tightness of the chamber after the explosion.

The objective and technical result of the utility model is to create a sealed explosion-proof chamber of repeated use for transportation and liquidation of explosive devices, equipped with interchangeable body protection elements from the side of the shock wave and fragments.

The technical result is achieved in that the explosion-proof chamber includes a spherical body, a sealed inlet and a splinter protection located inside the chamber, the housing being placed on the base, a sealed inlet made in the lower part of the housing in the form of a neck with a flange overlapped by a power cover, the splinter protection is made in the form of an internal and the outer rows of metal pipes placed with gaps on the supports of the arch type so that the pipes of the outer row overlap the gaps between the pipes of the inner row, arch type support mounted on the drive dialed from the steel plates and placed on the surface of the energy absorbing material filling the lower part of the chamber.

The technical result is also achieved by the fact that opposite the ends of the metal pipes are additionally placed rectangular screens drawn from steel plates; the power cover is connected to the neck flange by a bayonet lock; part of the inner chamber is filled with an energy-absorbing material selected from the group: expanded polystyrene, polyurethane foam, expanded polystyrene chloride, expanded polystyrene concrete, expanded polyethylene; anti-splinter protection pipes are connected using energy-absorbing material; the explosive device is located on the lower disk.

The design of the explosion-proof chamber according to a utility model is shown in Fig. 1 and 2, where:

1 - spherical body;

2 - sealed entrance;

3 - splinter protection;

4 - base;

5 - a mouth with a flange;

6 - power cover;

7 - the inner row of metal pipes;

8 - the outer row of metal pipes;

9 - support arch type;

10 - disk, recruited from steel plates;

11 - energy absorbing material;

12 ′, 12 ″ - rectangular screens made of steel plates

13 - a lock ring of a bayonet lock

14 - explosive device.

The housing of the explosion-proof chamber according to a utility model was made of high-strength steel. A chamber made in the form of elements of a spherical body 1 connected by welding, a sealed inlet 2 made in the lower part of the body in the form of a neck 5 with a flange overlapped by a power cover 6. The body 1 is mounted on the base 4, with which the camera can be placed on vehicle (car body or car trailer). The neck 5 with a flange serves to load an explosive device into the chamber and for tight connection with a power cover 5, which is blocked by a bayonet lock (by turning the lock ring 13 of the shutter). Additionally, the lids may contain means for connecting (hinges, swivel arms, etc.) to the housing 1 or base 4 (not shown).

Inside the chamber there are elements of anti-fragmentation protection 3, which is made in the form of internal 7 and external 8 rows of metal pipes placed with gaps on the supports 9 of the arch type so that the pipes of the outer row 8 overlap the gaps between the pipes of the inner row 7, and the supports 9 are arched mounted on a disk 10, recruited from steel plates and placed on the surface of the energy-absorbing material 11 filling the lower part of the chamber.

The bayonet lock ensures tightness of the connection, safe pressure relief and reliable operation with repeated exposure to the blast wave from the inside of the container.

Before installing the explosive device 14, a part of the chamber volume (near the bottom, cover, gaps between the anti-splinter protection plates and the housing, etc.) is filled with energy-absorbing material 11 selected from the group: polystyrene foam, polyurethane foam, polyvinyl chloride, expanded polystyrene concrete, polyethylene foam, which are foam polymers and effectively extinguish a blast wave and absorb fragments. After the foam polymer has hardened, a disk 10 is mounted on its surface, which is collected (laid out) from steel plates. A rectangular screen 12 ′, assembled from steel plates, is first installed on the surface of the disk 10, so that the plates are opposite the ends of the metal pipes 7 and 8. Then, supports 9 of the arch type, equipped with pins for fixing the pipes 7 and 8, which placed on the support 9 in two rows so that the pipes of the outer row 8 overlap the gaps between the pipes of the inner row 7. In this case, the anti-splinter protection pipes are connected using energy-absorbing material. After that, a rectangular screen 12 ″, assembled from steel plates, which overlaps the neck section 5, is mounted on the surface of the disk 10.

After installing the explosive device 14 placed on the disk 10, the container is sealed by connecting the power cover 2 with the end of the neck 5 with a bayonet lock (by turning the locking ring 13)

After the explosive device is detonated, the pressure is released using a bayonet lock and the destroyed and deformed protection elements from the effects of the shock wave and fragments are removed from the chamber.

Tests of the camera showed the possibility of a fairly simple extraction of the destroyed and deformed security elements from the camera, their replacement and the repeated use of the camera according to a utility model for transporting and eliminating explosive devices.
