Description

The invention relates to the field of localization of the effects of explosive mechanisms and can be effectively used to suppress fragmentation and high explosive impact, thereby minimizing damage from explosions resulting from terrorist attacks.

Currently, a wide range of products designed to localize explosions is used in special equipment. As a rule, these are containers made of high-strength materials, capable of withstanding the high-explosive fragmentation of explosion products when explosive devices of a given mass are triggered.

Known, for example, an explosive reservoir with an external protective shield according to US patent 4833967, IPC F 42 In 37/00, publication 30.08.1989

The disadvantage of all container-type devices is the need to deliver the detected item (explosive device) with subsequent loading (with risk to life) in the container. Another disadvantage is that when the explosive charge exceeds the container’s safety margin, all destroyed metal structures will be additional damaging elements.

It is also known a device for localizing the effects of explosive mechanisms (bombs) according to patent 2125232, MCP F 42 B 33/00, publication 01/20/1999, the device contains one or more containers enclosed in a shell of elastic material filled with a non-combustible liquid (dispersant), and handle for delivery and installation. A cavity is made in the lower part of the tank. Along the contour of the peripheral part of the tank, an anti-splinter screen of high-modulus fabric in the form of a skirt is additionally installed. The energy of a shock wave passing through a liquid is spent on the formation of turbulent flows and is extinguished due to surface tension and viscosity.

The disadvantage of this device is the insufficient efficiency of the high-explosive action of the explosion as a result of the early destruction of the localizer due to the possible asymmetric placement of the charge in its cavity, as well as the location of the charge near the shell. The disadvantage of this device is the possibility of undermining covered by the specified device localization of the explosive device using a remote radio fuse.

The closest in essence is the explosion localization device according to the patent of the Russian Federation No. 2193749 class F 42 D 5/04. This device contains one or more dispersant-filled containers enclosed in a sheath of elastic material with the formation of a cavity in the lower part to accommodate an explosive device. A layer of material is made on the surface from the cavity side, which does not form hazardous fragments upon destruction.

The disadvantage of the prototype is the design complexity, the possibility of undermining covered with the specified device localization of the explosive mechanism using a remote radio fuse. Such a detonation is undesirable, as it happens unexpectedly, at the moment chosen by the attackers to inflict the most damage, for example, when trying to study an explosive device.

The objective of the present invention is to eliminate the disadvantages of the prototype, namely the creation of a localizer that provides effective protection of people and structures from high-explosive, fragmentation when explosive mechanisms explode, simplifying the design -

 to make it more reliable, the mounted system, powered by a portable source, allows you to destroy electronic devices used to remotely detonate explosives.

The specified technical result is achieved in that the device for localizing the effects of explosive mechanisms, see figure 1, contains a housing 1 made in the form of a shell of elastic material. The shell has the shape of a cap in order to make it possible to place explosive mechanisms under it. In this case, an elastic shell made of rubber with the addition of special fillers is additionally reinforced with a non-metallic mesh 2 of a flat or three-dimensional type of honeycomb to increase the resistance to explosion. Window 3, which is plugged back with a stopper, is made for penetration of special equipment under the hood in order to study the danger of the object or its destruction. Two rubber handrails 4 serve for ease of transfer and device. Along the entire perimeter of the device are weighting agents 5 for more tight contact with the surface on which the device is installed and to strengthen its edges. Induction coil 6, wire 7, in the form of an integrated system, powered by a portable generator 8, prevent the operation of explosive mechanisms.

The proposed device for localizing the effects of explosive mechanisms works as follows.

The device using the handrail 4 is installed on the detected suspicious object 9 in such a way that the body (cap) 1 allows you to completely separate it from the surrounding space. In this case, through the reverse plug-window 3, special equipment penetrates under the cap in order to study the danger of the object or its destruction. The built-in system, powered by a portable generator, prevents the operation of explosive mechanisms and allows you to use the device to localize the effects of explosive mechanisms repeatedly: to render explosive devices neutralized, at railway stations, airports, bus stations, stadiums, schools, playgrounds, etc.
