Description

EXPLOSION PROTECTION

The utility model relates to explosive technology, in particular, to ensuring the safe disposal of explosive objects, for example, subversive explosive devices. These devices, as a rule, contain the main charge of a blasting explosive (BB), connected by a detonation line with a detonator and a detonator activation system.

A device for the destruction of various objects, documents, instruments is known, which is a cartridge filled with a pyrotechnic composition, having openings with an igniter composition pressed into them (UK application No. 1414758, publication 1975). The disadvantage of this device is the danger of its use for the environment, because the facility is burned, and if it turns out to be explosive, mechanical damage can occur in the explosion zone.

An explosive device for detaching suspicious devices at a distance is also known (French application No. 2558949, publication 1975). It is taken as the closest analogue. The device has a flat charge ejected by gas pressure, which ensures the neutralization of devices of an allegedly explosive nature. A flat charge is formed by a flowable substance, cured with a binder. To eject a flat charge from the case, an explosive charge is used, the initiation of which is provided by the detonator. All components of the device are housed in a housing. The device serves for a quick attack with the goal of neutralizing suspicious objects through thin partitions at a distance.

IPC R42D 5/04 The disadvantage of this device is the explosive nature of the disposal,

leading to danger to others, providing relative safety for the attacker. The technical problem to be solved is to create a device for reliable, safe for surrounding disposal of explosive objects such as sabotage WU. The safety of disposal can be ensured by the minimum probability of explosive destruction.

Expected from the implementation of the claimed device, the technical result consists in neutralizing the WU without detonating the main charge of the blasting WB by destroying the elements of the WU. It should be borne in mind that sabotage WU can be disguised as household items, therefore, the possibility of a preliminary study of the location of elements WU,

The stated technical problem is solved by a device for the disposal of explosive objects, containing, like a prototype, an explosive charge enclosed in a housing and an initiating device. The difference from the prototype is the implementation of the charge In In the form of groups of axisymmetric cumulative charges evenly placed in the matrix, and the groups of cumulative charges and cumulative charges in groups are connected in series with the explosive rods with the initiating device. The explosive charge may also include an additional linear explosive charge at the periphery of the matrix, connected by an explosive rod with the last cumulative charge. In addition, the parameters of the cumulative charges are determined by the ratio:

and 70 ° ... 100 °; 0.2 - 2, where:

a is the angle of the cumulative recess;

2 The implementation of the IBB charge in the form of groups of axisymmetric cumulative charges,

placed evenly in the matrix, you allow a high degree of probability to achieve the defeat of the elements of an explosive device, mainly a blast explosive charge. This is especially significant for WUs disguised as various household items (bags, bags, suitcases, etc.). The interval between charges is selected based on the expected dimensions of the WU and the exclusion of the mutual influence of charges on each other.

The serial connection by rods of explosive groups of cumulative charges to cumulative charges in groups is used to mitigate the pulse loading of an explosive object and to exclude the effect of charges on each other. The addition of a linear explosive charge to the last cumulative charge with the 18V rod excludes the influence of the latter on the cumulative charges in the matrix and softens the pulse loading of an explosive object.

The choice of the parameters of the cumulative charges is made, taking into account the features of the objects to be neutralized. Explosive objects may contain explosives of different sensitivity. When neutralizing them, it is necessary that the cumulative jet, acting on the explosive, does not cause an explosion and detonation. For this purpose, relations are introduced that limit the possibility of an explosive (detonation) process:

0.2 - - 2; a-70 ° ... 100 °

It is known that a decrease in the angle of cumulative excavation at - const

leads to an increase in the velocity of the cumulative jet and, accordingly, an increase in pressure in the medium affected by the jet. And this increases the gravity. Part of the explosion of the explosive object of neutralization. In addition, in this case, the gradient of the B jet increases, the jet becomes unstable and the cutting of the ape.

armor penetration. It was experimentally established that exceeding the cumulative recess angle of 100 ° leads to such a slow collapse of the cladding that the jet becomes short and armor penetration A drops sharply when the angle a decreases below 70 °, the cumulative jet is unstable, and has a high speed, which sharply increases the likelihood of an explosion

At - const within the indicated limits of the angle a 70 ° ... 100 °

effective penetration at the minimum probability of an explosion of a В1В object. To limit the velocity of the cumulative jet, the ratio between the mass B in the charge and the mass of the liner is experimentally not

0, 2. This ratio determines the maximum speed

lining and, accordingly, the speed of the cumulative jets after collapse

Attracting the jet velocity is less than the value at which it is possible

jet formation, - 2 even in the range a 70 ° ... 100 ° cumulative speed

the jet becomes high and the likelihood of an explosion of the object being neutralized increases.

Fig. 1 shows a sectional view of the device.

Fig. 2 - device, top view.

The neutralization device comprises a housing 1, an initiating device 2, a matrix 3 placed in the housing, uniformly placed in the cumulative charges 4 in groups B, C, D, and on the periphery of the matrix 3 there is a linear charge BB-5. The groups of cumulative charges and cumulative charges 4 in the groups (B, C, D) are connected in series with the BB-6 rods with initsdaru. device, the last cumulative charge is also connected to the rod y. 3b with a linear charge BB-5. Parameters of cumulative charges choose ps

the specified ratio.

The device operates as follows. The neutralization device is placed on the object. They make use of the initiating device 2 groups B, C, D of cumulative charges 4, triggering sequentially. Cumulative charges 4 form a system of shock waves and rarefaction waves in the object to be neutralized. In this case, mechanical destruction of the elements of the object of neutralization occurs. Significant pressures arising from the zone of action of the cumulative jet during its interaction with the explosive object, lead to chemical reactions and energy release. The energy of expansion of products from the reaction zone further enhances the mechanical destruction of the elements of the object. Since the linear charge of 5 explosives located on the periphery of the matrix 3 is fired last and farthest from the central zone, its explosion finally separates the parts of the object destroyed by cumulative charges 4, thereby achieving a complete removal of the object to be neutralized from the working state.

Thus, the specified set of design features provides reliable disposal of explosive objects by their safe destruction, eliminating the explosive (detonation) process in the explosive object.
