Description

The utility model relates to the field of industrial explosive devices, namely to the designs of directional charges, and can be used for crushing rocks, making holes in metal and concrete structures, creating depressions (boreholes) in the ground, as an element of the design of devices (perforators) for creating channels (holes) in boreholes (wells). The device can also be used to eliminate (destroy) explosive objects (including ammunition) by exposing them to a cumulative wave from the detonation of explosives (in the case of using a charge without lining) and/or a cumulative metal stream (when using a charge with lining).

A device for destroying explosive objects is known, containing a propellant charge and a destroyer placed in an indestructible housing, which is made open on two opposite sides, and in it are successively placed a destroyer in the form of a set of high-strength rods, a propellant charge of explosive and a wave damper in the form of a crystalline bulk material enclosed in an easily destructible shell (RU 2154255).

The disadvantage of the device is its inability to destroy standard ammunition or improvised explosive devices based on them in field conditions.

The prototype of the claimed device is a device for the destruction of explosive objects, including standard ammunition and improvised explosive devices, containing a propelling charge of explosive and a throwing element placed in a housing, characterized in that the throwing element is made in the form of a concave disk with a curvature towards the propelling charge of explosive (RU 2500980).

The disadvantage of the device is the low efficiency of destruction of standard ammunition or improvised explosive devices based on them in field conditions, as well as the limited functionality of the known device.

The technical problem that the utility model is aimed at solving is to expand the arsenal and increase the efficiency of such technical means that ensure the disposal of charges based on high explosives in field conditions and their reuse for the manufacture of charges of industrial explosives, as well as to expand the functionality of the device.

The technical result achieved through the use of the utility model consists in the utilization of various charges in field conditions.

The essence of the utility model is that in a universal cumulative charge containing a housing, an explosive substance and a housing cover, the housing is made axially symmetrical with a central axial opening, a protrusion on one side along the axis and a seat on the other side of the axis, wherein the seat is partially filled with an explosive substance, and a detonator is inserted into the central axial opening.

Mostly, the explosive in the saddle is covered by a projectile element made in the form of a cumulative funnel.

Mostly, a plate with a central hole is placed on the housing protrusion and clamped with a nut screwed onto the housing protrusion, while additional holes are made in the plate, located along the periphery of the plate.

Preferably, the charge contains a mounting block on “bending” legs made of plastic or soft metal wire, and the legs are fixed to a plate with a central hole and are designed with the ability to vary the distance from the charge to the object of impact from 0 to 500 mm.

The design of the cumulative universal charge and the diagram of its use are explained by drawings.

Fig. 1 shows a general view of the assembly of a cumulative universal charge.

Fig. 2 shows a general view of the assembly of a cumulative universal charge with a projectile element.

Fig. 3 shows a diagram of the arrangement of a cumulative universal charge above the target, fixed on “bending” legs.

The universal cumulative charge contains a housing 4, an explosive substance 3 and a housing cover 1, the housing is made axially symmetrical with a central axial opening, a projection 8 on one side along the axis, and a seat on the other side of the axis, wherein the seat is partially filled with an explosive substance 3, and a detonator 7 is inserted into the central axial opening, wherein the explosive substance 3 in the seat is closed by a projectile element 2, made in the form of a cumulative funnel. A plate 5 with a central hole is placed on the projection 8 of the housing 4 and clamped with a nut 6 screwed onto the projection 8 of the housing, and additional holes 9 are made in the plate 5. The charge fastening unit is made on “bending” legs 10, plastic or made of soft metal wire, wherein the legs 10 are fixed on the plate 5 with a central hole and are made with the possibility of varying the distance L from the charge to the object 11 of influence in the range from 0 to 500 mm.

The universal cumulative charge is used as follows.

The charge can be used to crush rocks, make holes in metal and concrete structures, create depressions (boreholes) in the ground, as a design element of devices (perforators) for creating channels (holes) in boreholes (wells). The device can also be used to eliminate (destroy) explosive objects (including ammunition) by exposing them to a cumulative wave from the detonation of explosives (in the case of using a charge without a projectile) and/or a cumulative metal stream (when using a charge with a projectile).

The charge is a universal cumulative charge, contains a housing 4, an explosive substance 3 and a housing cover 1, the housing is made axially symmetrical with a central axial opening, a projection on one side along the axis, and a seat on the other side of the axis, wherein the seat is partially filled with explosive substance 3, and a detonator 7 is inserted into the central axial opening. The charge is detonated by the detonator 7. The destruction of explosive objects (the object 11 of impact) is carried out by acting on it with a cumulative wave from the detonation of explosive substance 3 (in the case of using a charge without a projectile element 2) and/or a cumulative metal stream (when using a charge with a projectile element 2).

The charge fastening unit is made on “bending” legs 10, plastic or made of soft metal wire, and the legs 10 are fixed on a plate 5 with a central hole and are made with the ability to vary the distance L from the charge to the object 11 of impact in the field in the range from 0 to 500 mm.

A plate 5 with a central hole is placed on the projection 8 of the housing 4 and clamped with a nut 6 screwed onto the projection 8 of the housing, and additional holes 9 are made in the plate 5.

The charge is hermetically sealed when assembled, which prevents foreign objects from entering the cumulative recess and allows it to be used underwater.

The charge can be used to create a cumulative effect, both with and without a funnel (lining). This will allow differentiation of the cumulative effect and its impact for different materials and in different application conditions.

The charge can be used individually (with detonation through the axial channel).

The charge can be installed, suspended, to the object 11 of impact at an adjustable distance L, to enable regulation of the force of impact of the detonating wave.

The charge can be made of any materials and their combinations that allow fixing its components and ensure its operability under the conditions of its use. In particular, these can be metals, plastics, wood, glass, plaster, concrete, silicones or their combinations. Also, explosive materials can be used as charge body materials, such as solid rocket fuels based on nitrocellulose or rubbers, which in the process of using charges enhance its effect on the object, especially in closed spaces, due to the formation of an additional volume of gases.

The charge is preferably assembled directly at the place of its use, in the configuration and from the materials of the housing and fastening (installation) in order to best meet the tasks facing the consumer.

Explosive materials, in particular the explosive charge (briquette), are preferably transported and stored separately from the other components of the device. This increases the safety of handling them and significantly reduces the costs for these purposes. This will also allow the devices to be supplied to different consumers in accordance with the various purposes of their use.

Thus, by using the declared technical solution, it is possible to implement the disposal of various charges, crush rocks, make holes in metal and concrete structures, create depressions (boreholes) in the ground, and create channels (holes) in wells (wells).
