Description

 The invention relates to the field of special equipment and is used in the disposal of explosive objects. The presented device for localizing the effects of explosive devices reduces shrapnel and thermal effects during an explosion, dampens shock and acoustic waves, and also shields radio signals, preventing the initiation of a radio fuse.

 Known devices in the form of cylindrical chambers and containers made of high strength steels and alloys. For example, manufactured by the research and production enterprise "Ecotest", the city of Sarov, Nizhny Novgorod region. These devices are able to withstand high-explosive fragmentation of explosive products when explosive devices are triggered, the power of which does not exceed a given value. In addition, these devices completely shield radio signals and do not allow the detonation of an explosive device using a remote radio fuse.

 Also known is a protective device for localizing the explosion (see AS 1596925, MKI G 01 N 33/22, publ. 10.07.95), containing a rotational sheath and an inner shell in the form of ring strips of sheet material with a regulated gap.

 Also known is a reservoir for an explosive with an external protective shield (see US patent 4833967, MKI F 42 B 37/00, publ. 30.06.89).

 A common drawback of these container-type devices is the need for delivery and loading into the container of an explosive device or object that may turn out to be. During such delivery, the likelihood of explosive devices being triggered increases, and if this delivery is carried out by people, the risk becomes unreasonably great. Mechanisms for delivering explosive items are complex and expensive. Another disadvantage is that when the bomb's charge power exceeds the container's safety margin, its destroyed metal structures will be additional damaging elements. In addition, the metal, being a crystalline substance, conducts acoustic waves well, into which the shock wave is converted after collision with an obstacle insurmountable for it, in this case the wall of the device. Powerful acoustic signals can also be a damaging factor, affecting primarily the hearing organs.

 A device (bomb inhibitor) is known according to US patent 4836079, MKI F 42 B 33/00, C 06 V 21/00, publ. 06/06/89, containing a flexible container filled with liquid (usually water), and a handle. The disadvantage of this invention is the lack of a layer that provides protection from fragments of the shell of an explosive device and other solid (shot, buckshot, etc.) bodies that start explosive devices to increase their damaging ability.

 As a prototype that does not have the disadvantages of the above analogues, the device for localizing the effects of explosive devices according to the patent of the Russian Federation 2125232, MKI F 42 V 39/00, F 42 V 33/00, publ. 01/20/99. The device comprises one or more containers with a shell made of an elastic material filled with a non-combustible liquid, with the formation of a cavity in the lower part, and a handle for delivery and installation. An anti-splinter screen made in the form of a “skirt” of high-modulus fabric is additionally installed along the contour of the peripheral part of the tank. 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. At high-speed loads, for example, when fragments hit, these forces are so great that the resistance of the liquid mass to high-speed loads is comparable to the resistance of solid crystalline bodies. Moreover, the use of a liquid as an obstacle for a shock wave is preferable, since when the localizer of explosive devices is destroyed, the liquid does not become a dangerous damaging element, and the energy of the shock wave is spent on its dispersion.

 The disadvantage of the prototype is the possibility of undermining covered with the specified device localization of the explosive device 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 device that prevents the penetration of a signal to an explosive device and, therefore, prevents its undermining using a radio fuse.

 The specified technical result is achieved in that the device for localizing the effects of explosive devices contains a container with a shell made of elastic material filled with a non-combustible liquid with the formation of a cavity in the lower part, a handle for installation, an anti-splinter screen and an additional screen that prevents the initiation of a remote radio fuse, which upon destruction does not form damaging elements.

 Despite the fact that the radio signal can penetrate the explosive device from the side of the supporting surface (if it does not have shielding properties), it will in most cases be weaker than the one for which the radio fuse is designed, and will not lead to its operation. Thus, the presence of a screen significantly reduces the likelihood of an explosive device triggering when using a radio fuse, primarily when trying to detonate an explosive device from long distances that are most convenient for attackers. In cases where an explosive device is installed on shielding surfaces, for example, on a metal floor in wagons, airplanes, etc., the explosive device is shielded from the supporting surface, which further reduces the likelihood of a fuse being triggered.

 The present device for localizing the effects of explosive devices is illustrated in the drawing, which shows a cross section of a device for localizing the effects of explosive mechanisms with one working capacity, where 1 is the handle; 2 - an explosive device placed in a suitcase (a suspicious object), 3 - a working cavity of the device, 4 - a container of elastic material (rubber), 5 - a non-combustible liquid, 6 - a shatterproof screen made of Kevlar fabric, 7 - a shielding layer ( metallized film).

 A device for localizing the effects of explosive devices works as follows.

 The device for localizing the effects of explosive devices using the handle 1 is installed on the detected suspicious object (explosive device) 2 so that the cavity 3 made at the bottom of the device completely separates the detected suspicious object 2 from the surrounding space. In this case, the shielding layer 7 prevents the penetration of the radio signal to the explosive device, making it difficult to undermine it using a radio fuse. In the event of an explosion (as a result of the initiation of the fuse in another way) of the object thus covered, the energy of the explosion and most of the fragments are absorbed by the elastic shell 4 and non-combustible liquid 5. The remaining part of the fragments is delayed by the anti-fragmentation screen 6.

 Thus, the proposed device for localizing the effects of explosive devices provides effective protection of people and structures from high-explosive, thermal and fragmentation when explosive devices are triggered. It also prevents the operation of explosive devices using a radio fuse.

 The use of the proposed technical solution does not require additional investment in places of use.
