Description

 The proposal relates to containers for transporting, storing and detonating an unknown explosive device with the elimination of manual decontamination in most cases. The container can also be used to detonate an explosive device at its location. Reactors are known which are equipped with a housing with an active zone located inside it, and the reactor housing is designed for the possibility of an explosive process when high pressure and temperature occur inside it. The housing is designed for an internal pressure of 200 ati.

 A disadvantage should be considered that it is not portable and the elements of energy absorption are not provided for in the explosive process. Known containers for transporting sealed radioactive sources, which contain a housing, a lid and a base. Containers are calculated on the permissible radiation power on its surface and strength for unforeseen circumstances, for example, a third-party explosion.

 The disadvantage of such a container should be considered that it is not able to extinguish the energy of an internal explosion, which can occur even when storing radioactive substances, for example, when the temperature rises.

The closest analogue of the invention is a container for an explosive device according to US patent [1]
The known container comprises a housing, a lid located on top and a clip located inside the housing.

The aim of the proposal is to address these shortcomings, namely:
the ability to store an explosive device for a long time;
the possibility of transporting an explosive charge while ensuring safety when it is triggered at an unexpected moment;
the possibility of neutralizing the charge by actively influencing it;
extinguishing the energy of the explosion in all cases, which allows to reduce the weight of the container and make it portable, which is important when neutralizing detected unknown explosive devices in populated areas.

 This goal is achieved by the fact that a removable cage of shells of mesh material is placed inside the housing, between which a flexible and sealed container of water is placed, and electrical inputs and a holder with a subversive charge are located in the lid.

 Figure 1 shows a section along the axis of the container, figure 2 input electric. The container contains a housing 1 with a stand 2 and a cover 3. In the housing there is a ferrule 4 of disposable mesh material. The clip itself is made in the form of two shells 5, 6, between which a flexible container 7 with water is placed. The container 7 is sealed and made of readily destructible material, for example, polyethylene. In the lid 3 there are electrical bushings 8, which are placed in channels 9 with an insulating compound, for example from BF-4 and two bushings 10 with electrical insulating coatings on contact surfaces with bushings 8, which can be made in the form of oxide on the surface. In the upper part of the cover there is a holder 11 for installing a subversive charge 12. On the cover 3 there is a handle 11.

 The container operates as follows. After detecting an explosive device of unknown origin and action, deliver the container on a cart or by transferring it manually to a charge with an open lid 3, a blasting charge 12 and a capacity of 7. Put the object of concern into the inner cavity of the cage, screw the lid 3 and transport the object in a sparsely populated place to undermine it. The handles 13 at the cover 3 are placed in such a way that during the production of an unexpected explosion they (handle 3) will fly up without causing damage to the operator. The most dangerous time is when the item is placed in the container cavity, because any other unforeseen explosive processes will be directed upwards and will not bring damage to the explosive charge-cutting ones. Therefore, it is desirable to remotely overload using, say, an electric car with a manipulator. If for some reason it is necessary to neutralize the explosive device in place, then connect the inputs 8 to the voltage source and undermine the charge 12, which should undermine the explosive device. During the explosion, thermal energy is generated, which leads to a sharp increase in pressure and there may be fragments from the explosive device. The release of energy leads to rupture of the tank 7 to the heating and evaporation of water. This process absorbs energy and does not allow the process of increasing pressure to develop until the entire hearth evaporates.

 This energy absorption allows you to get a controlled process, reduce the weight and wall thickness of the container or to obtain an increased margin of strength of the container.

 The following points should be made.

 1. Containers should be made according to the mass of the expected explosive charge, say 2, 4, 6 kg of explosives. It is this mass value at a glance or at an estimate that allows you to determine the use of a container from the specified row.

 2. The mass of water should be no less than the calculated one for absorbing the energy of the explosion.

 3. After the explosion, the container will heat up and its cooling will take time, which does not affect the situation.

 4. Transportation and blasting (even on the spot) already in a dream pose a danger to others.

 5. The container body itself can serve as a screen for obstruction from external signals if the explosive device is radio-controlled. The container can be listened for clockwork and illuminated to determine the explosive charge device.

Thus, the technical solution allows to achieve all the goals, namely:
maximize the safety of the neutralization of the charger;
minimize the weight of the container due to the use of an absorber of energy;
destroy the explosive device in place with safety and precaution;
transport to the place of detection and from it to the place of detonation by any means (up to manual).

Claims (1)

 A container for an explosive device, comprising a casing located on top of the lid and a cage located inside the casing, characterized in that the cage is removable and contains shells of mesh material, between which a flexible sealed container with water is placed, and electrical inputs and a holder with a subversive are located in the lid charge.
