RU49973U1 - SYSTEM FOR DISCONNECTING AN EXPLOSION DEVICE - Google Patents

Abstract

The utility model relates to safety measures in the elimination of explosive devices, especially those containing toxic components.

The essence of the utility model is to create a protective barrier, consisting of a liquid filled lower and filled with air-mechanical foam upper containers made of easily destructible material. The striking elements for the destruction of the explosive device are hydro-cumulative jets, which are formed when the surrounding HE is blown up, an elongated cumulative charge immersed in the liquid filling the cavity for the HE.

The technical result consists in the reliable localization of explosion products and the exclusion of pollution of the surrounding area with toxic substances.

Description

The system relates to the means of neutralizing and localizing the action of the damaging factors of the explosion of devices containing explosive charges (EX), especially with toxic components.

A device for localizing the effects of explosive mechanisms, according to US Pat. RU 2150670, publ. B. No. 16, 2000, which contains one or more containers filled with a non-combustible liquid, made of elastic material, with the formation of a cavity, an anti-splinter screen made in the form of a "skirt" of material based on high modulus fibers, fixed along the contour of the peripheral part of the container . The cavity containing the detected suspicious object allows you to separate it from the surrounding space.

This device provides protection of the surrounding space from high-explosive and high-explosive impact when explosive mechanisms are detonated at the place of their detection.

The disadvantage of this device is that it is effective for localization of the explosion of small quantities of explosives (EXPLOSIVES), but cannot provide reliable protection for the explosion of mechanisms with a large mass of explosives and toxic substances that create an air shock wave (IWV) of high power and high-temperature toxic aerosols .

The device according to US Pat. 2150670 adopted as a prototype, as the closest to the destination.

The technical task to be solved is the reliable localization of the explosion products during the disposal of explosive devices (VU) of high power of the order of 5 kg or more in TNT equivalent, containing toxic components that form high-temperature aerosols during the explosion.

The expected technical result is to prevent pollution of the surrounding area with toxic substances and the destruction of objects by an air shock wave during the disposal of the detected explosive device.

The specified technical result can be provided by a system containing one or more containers filled with a working medium of readily destructible material forming a cavity for placement of an explosive device to be neutralized in it.

The lower tank, located on the supporting platform around the VU, is filled with non-combustible liquid. The upper tank is installed in such a way that it covers the specified WU from above and from the sides.

What is new in the system is that an elongated cumulative charge (UKZ) is placed in the cavity for the explosive device, surrounding the AS with a gap and oriented by a cumulative recess to the center of the cavity.

The upper tank is filled with air-mechanical foam. The cavity for the WU is filled with a non-combustible liquid to a level equal to or slightly higher than the level of the intended placement of the WU.

The presence in the system of an elongated cumulative charge, installed with a gap with respect to the VU, and immersed in the liquid, allows using the cumulative jets acting on it with counter-directed pulses as a damaging element for destroying the VU.

Filling the upper tank with air-mechanical foam creates an obstacle for an air shock wave and volatile aerosols moving with it.

The figure shows a system for the disposal of WU.

It consists of a lower container 1 filled with a non-combustible liquid, for example, water. The upper container 2 is filled with air-mechanical foam, for example, fire. In the cavity formed by the capacity 1, an elongated cumulative charge 3 is placed, surrounding the neutralized explosive device 4 with a gap.

The specified cavity is filled with a non-combustible liquid 5, for example, water, so that WU and UKZ are immersed in it. The containers are made of easily destructible material, for example, elastic waterproof fabric.

The system operates as follows.

When it becomes necessary to render explosive device 4 neutral, a lower tank 1 is installed at the site of its detection, closing it with an area around the VU. Then, an elongated cumulative charge 3 is placed with a gap along the VU contour, charge 3 is remotely connected to an initiating device (not shown). After that, the WU and UKZ are covered with the upper capacity 2 filled with foam. The lower surface of the tank 2 is made with a recess for placement of the VU and UKZ. The cavity formed by the upper 2 and lower 1 containers is filled with non-combustible liquid 5 to a level equal to or slightly higher than the level of VU. The upper container 2 is filled with air-mechanical foam. After that, remote blasting of the UKZ immersed in the liquid is carried out. With the undermining of the UKZ, hydro-cumulative jets are formed, aimed at the WU towards each other. They can destroy it without detonation of explosive charge or with detonation. With the detonation destruction of the WU, the explosion products in the form of an air shock wave and high-temperature toxic aerosols rush to the tank 2.

During the interaction of the water waves with foam bubbles, the energy of the water waves is absorbed due to the destruction of the bubbles and the bonds between them. Aerosols, falling into the foam layer with the HVW, also lose their energy. Moreover,

there is a rapid cooling of both explosion products and aerosols due to the effective evaporation of liquid in the thin walls of the foam bubbles. Thus, there is a weakening and cooling of the explosion products and excludes their exit beyond the limited capacitance of the cavity.

After neutralizing the WU, it is enough to collect containers with the remaining WU and explosion products remaining in them, without polluting the surrounding area.
