Explosion proof urn

The utility model relates to garbage containers, namely to bins set up in the streets and in public places.

A known waste collection containing a housing formed by a lid, the bottom of the cusps and the outer walls located vertically to the bottom to form an internal volume divided by internal walls into several compartments (RF patent No. 2038271, IPC B65F1 / 00, publication 1995).

A known waste container containing a housing, a base and a removable lid with a hole for dumping garbage (utility model of the Russian Federation No. 11187, IPC B65F1 / 00, publication 1999).

Known waste container containing a housing and a clamp

hoop, while the body is made in the form of a parallelepiped with rounded edges (utility model of the Russian Federation No. 18268, IPC B65F1 / 00,

2001 publication).

Known devices do not provide the ability to reduce the consequences of explosions resulting from terrorist acts by laying various explosive devices in containers for garbage collection.

IPC B65F1 / 00

 J, - f.

A known container for accommodating aggressive materials, comprising a housing, on the inner surface of which is glued an elastic sheath made of polyethylene film, which is equipped with a protective insert made of polystyrene from the outer CTOipOHbi (patent of the Russian Federation No. 2039695, IPC B65F1 / 00, publication 1995).

A container for hazardous waste is also known, including a sealed enclosure and a chamber for preliminary accumulation of waste placed under its upper face (RF patent No. 1822851, IPC B65F1 / 00, publication 1993).

These containers also do not provide suppression of fragmentation, high-explosive and thermal effects during explosions of objects laid in containers during terrorist acts.

The task of creating this utility model is to expand the arsenal of technical tools used to collect garbage on the streets and in public buildings, and to create such a garbage can design that would enable the localization of the effects of explosive devices and thereby reduce the effects of shrapnel, high explosive or thermal effects during commission of terrorist acts.

The essence of the claimed utility model is as follows.

The waste bin contains a housing formed by a cylindrical wall and a bottom. The housing is made integral and includes an internal

the casing and the outer casing covering it at a distance with the formation between their cylindrical walls and the bottoms of the cavity.

Both cases are rigidly interconnected in the upper part by means of an annular plate, with the upper end of the cylindrical wall of the outer casing protruding above the upper end of the cylindrical wall of the inner casing. A cup-shaped insert having an outer flange along the upper

the end face, through which the liner rests on the protruding end face of the cylindrical wall of the outer casing, and the diameter of the flange of the liner exceeds the outer diameter of the outer casing. Through holes are made in the annular plate. The cavity between the inner and outer shells is filled with a porous material, such as polyurethane foam.

All elements of the ballot box body and liner are made of alloy steel.

The thickness of the cylindrical wall and the bottom of the outer shell is 9-11 mm, the thickness of the cylindrical wall and the bottom of the inner shell is 1-3 mm, and the distance between the walls and the bottoms of the inner and outer shells is 70-90 mm.

The height of the urn is 680-720 mm, and the outer diameter is 480-520 mm.

The outer diameter of the urn exceeds the inner diameter of the liner by 2-3 times.

The figure shows the proposed explosive ballot box, a longitudinal section.

The urn contains a hull consisting of an inner 1 and an outer 2 hulls. The inner case includes a cylinder wall 3 and a bottom 4, and the outer case includes a cylindrical wall 5 and a bottom 6. A cavity 7 is formed between the bodies 1 and 2, filled with porous material 8, for example, polyurethane foam. The cylindrical walls of both cases are interconnected by means of an annular plate 9, while the wall 4 of the extruded body protrudes above the wall 5 of the inner case. A cup-shaped insert 10 with an outer flange 11, supported by a protruding end of the wall 4 of the outer casing, is placed inside the inner case with a gap. Through holes 9 are formed through holes 12.

All elements of the ballot box are made of alloy steel, while the walls and bottoms of the bodies and parts of the liner are connected by welding.

In the case of an explosion of an object embedded in the urn, the proposed design leads to a decrease in the energy of the explosion, while a significant fraction of the energy of the explosion and most of the fragments are absorbed; it is made of porous material and the walls of the body and liner.

Thus, the proposed ballot box allows to reduce the consequences of fragmentation, high explosive or thermal effects during the commission of terrorist acts.
