Abstract

FIELD: special equipment, applicable effectively for suppression of fragmentation and high-explosive effects, thus minimizing the injuries caused by blasts as a result of acts of terrorism. SUBSTANCE: the device has one or more vessels made of elastic material filled with incombustible liquid, handle for carrying and installation on detected suspicious object, and an antifragmentation shield made in the form of a "skirt" of high-modulus fabric fastened on the outline of the vessel peripheral part. A cavity is made in the lower part of the vessel accommodating the detected suspicions object and allowing the latter to be separated from the surrounding space. EFFECT: enhanced efficiency of protection especially against fragments of hand grenades. 3 cl, 1 dwg

Description

 The invention relates to the field of special equipment and can be effectively used to suppress high-explosive and high-explosive impacts and, thereby, minimize damage from explosions resulting from terrorist attacks.

 Currently, special equipment uses a wide range of products designed to localize explosions. As a rule, these are cylindrical chambers or containers made of high-strength steels and alloys and incorporating one or more shells capable of withstanding the high-explosive fragmentation of explosion products when explosive devices of a given mass are triggered. Devices of this type can now be seen in the lobby of Moscow metro stations.

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

 A common drawback of these container-type devices is the need to deliver the detected item (explosive device), followed by loading (with a risk to life) into the container. The second disadvantage is the difficulty in the subsequent diagnosis of an object (bomb) located behind a thick-walled container armor, which is necessary for the detonation of an explosive device. Finally, the third drawback is that when the charge of the bomb exceeds the safety factor of the container, its destroyed metal structures will be additional damaging elements.

 As a prototype, devoid of the disadvantages of the above analogues, the selected device (bomb inhibitor) according to US patent N 4836079, MKI F 42 B 33/00, C 06 B 21/00, publ. 06/06/89), containing a flexible container filled with liquid (usually water) and a handle.

 The disadvantage of the prototype is the insufficient level of suppression of fragmentation of hand grenades.

 The aim of the present invention is to eliminate the disadvantages of the prototype, namely: the creation of a device that provides complete and guaranteed protection of people and structures from high-explosive and fragmentation impacts when exploding hand grenades and other explosive devices.

 This goal is achieved by the fact that along the circumference of the peripheral part of the container made of elastic and elastic material and filled with non-combustible liquid, an anti-splinter screen is additionally installed, made in the form of a “skirt” of high modulus fabric, while a cavity is made in the lower part of the container.

 The authors are not aware of technical solutions with the combination of features indicated in the claims aimed at achieving the same goal as in the object claimed as an invention, therefore, the proposed technical solution meets the criterion of "significant differences".

 The invention is illustrated by the drawing, which shows the cross-section of two variants of devices for localizing the effects of explosive mechanisms (bombs) with one (left) and two (right) working tanks, where: 1 - handle; 2 - an explosive device placed in a suitcase (a suspicious item), 3 - a working cavity of the device, 4 - an elastic, elastic shell, 5 - a non-combustible liquid, 6 - an anti-fragmentation screen made of Kevlar fabric.

 A device for localizing the effects of explosive mechanisms (bombs) works as follows.

 Using the handle 1, the device is installed on the detected suspicious object 2 in such a way that the cavity 3 made at the bottom of the device completely separates the detected suspicious object 2 from the surrounding space. In the event of the fuse (explosion) of the object thus covered, the energy of the explosion and most of the fragments are absorbed by the elastic, 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 mechanisms (bombs) provides complete and guaranteed protection of people and structures from high-explosive and fragmentation impacts when exploding hand grenades and other explosive devices.

 Based on the foregoing, the present invention in comparison with the prototype provides a positive effect and has the criterion of "positive effect".

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

 Tests of the present invention were carried out in 1997 at the training ground in \ h 3526 p. Lebyazhye (St. Petersburg) with a positive result.
