Description

The invention relates to devices for the remote delivery of deactivating chemicals to an emergency situation where a spill, leak, etc. harmful chemicals.

An analogue of the developed device is a powder charge atomization system and an installation for its atomization (Patent for invention of the Russian Federation No. 2142305, IPC A62C 35/00, A61D 1/00, publ. 10.12.99) for remote extinguishing of gas and oil fountains, forest fires , liquid and solid combustible materials in terrestrial and underground conditions.

Installation of explosive spraying of materials includes a multi-barrel cassette consisting of a housing, which is a metal lattice structure on which a vertical thrust plate is fixedly mounted.

Trunks are inserted into the case of a multi-barrel cartridge; each barrel consists of a cylindrical part and a shaft end, which are separated by a rigidly fixed partition.

The shanks of the trunks are inserted into the thrust plate of the cassette body and secured to it using a fixing clip. A shutter is placed in the shank of the barrel, which is fixed by the shutter cover.

Each barrel contains a knockout charge, an igniter and a sprayable composition, and the knockout and sprayable composition are placed in separate easily destructible containers and, accordingly, the igniter is placed in the shutter.

The sprayable composition consists of a combination of heavy and light components. Mineral non-combustible fillers can be used as a heavy component, and an active component, such as dispersing, fire extinguishing, light and heat-shielding compositions, etc. can be used as a light component. Each of these components is enclosed in an easily destructible shell and placed in a container, in the following order: “first place easily destructible shell filled with a heavy component, then a shell filled with a light component, and then a shell with a heavy component, etc., and the number of shells filled x sprayed composition and placed in the container must be at least 3. In the drawing, the layered arrangement of the composition is not visible.

The explosive spraying unit is equipped with a two-link damper system. The first link of the damper system includes shock absorbers mounted on each barrel of the cartridge and made of elastic material, and which provide damping of the recoil during firing.

The second link of the damper system includes hydraulic compensators symmetrically located in the left and right parts of the multi-barrel cartridge relative to its vertical axis and provide additional damping of the recoil energy.

The multi-barrel cartridge is equipped with a lifting mechanism (not shown), with an elevation angle of -5 to +30 degrees. from the level of the horizon vertically and by a rotary mechanism (not shown in the drawing), which ensures rotation of the multi-barrel cartridge by 360 in azimuth.

The disadvantages of the analogue are the use of the installation only to extinguish fires, the need to create a structurally complex installation and shell.

The prototype of the proposed technical solution is a 37 mm mortar with a 37 mm mortar (Instructions for the design and use of a 37 mm mortar / Military Publishing House of the USSR Non-profit Organization, 1942). Schematic diagram of the device shown in figa, b. Instructions. The system includes:

Mina (fig.3.b):

1 - Case.

2 - Fuse.

3 - Bursting charge.

4 - Blow-out cartridge.

37 mm mortar (figa):

1 - Bell.

2 - Movable coupling.

3 - Mortar barrel.

4 - Striker.

5 - Ring.

6 - The breech.

7 - Shovel.

8 - Ball heel.

9 - Cork.

10 - Bipod.

11 - Lyric.

The disadvantages of the prototype are its possible use only for warfare of a destructive nature.

The objective of the invention is to develop a simple and reliable installation for remote delivery of liquid deactivating chemicals to the site of injury by harmful chemicals.

The problem is solved using the signs specified in the claims, such as a device for the remote delivery of liquid decontaminating substances to the site of injury or accident includes a mortar 1 (Fig.1a) and mine 2 (Fig.1b), containing the main body 3 with expelling cartridge 4 The main body 3 of the mine 2 is equipped with a tip 5 on the thread 6, made of a material different from the main body 3, for example aluminum. The internal cavity 7 of the mine is filled with liquid decontaminant 8.

The technical result of the above set of essential features - the improvement of the mortar installation allows you to create a simple and reliable technical solution for the decontamination of chemicals.

Installation eliminates the presence of people in the affected areas, which excludes infection.

The invention is illustrated by drawings, where Figa shows a mortar; on figb - mine deactivator.

The mortar consists of three main parts: the barrel 10, the shovel-base plate 13, the bipod 16 with the plug 15. The barrel 11 serves to direct the flight of the mine to the target when fired. In the muzzle, the trunk has a small bell 9 for the convenience of loading mines when loading. The pipe of the barrel 11 is connected tightly with the breech 12, which serves as the bottom of the barrel. The breech 11 is pressed into the breech 14, on which the capsule of the expelling mine cartridge is pierced. The tail part of the breech ends with a ball heel 14, which serves to swivel the barrel with a shovel (plate) 13. The barrel 10 and the shovel 15 in the hinge are made one-piece. Shovel (base plate) 13 is used to support the mortar in the ground when firing and transmitting recoil force to the ground. Bipod 16 serves to support the barrel in the ground when fired, which increases the stability of the barrel and improves firing accuracy. The bipod 16 in the stowed position is placed in the mortar barrel with lyre 15 towards the breech of the barrel. Before firing, the bipod 16 is connected to the barrel 10 using a spring lyric 17.

Mine deactivator is a shell assembled in one housing. The mine consists of: the main body 3, in which a tip 5 is placed in front of the projectile, designed to deform, depressurize and emit a liquid decontaminating substance when the mine hits an obstacle. The tip 5 is screwed by thread 6 into the main body 3 of the mine 2, after screwing the tip 5 represents one closed volume with the main body 3; deactivating chemical substance 8, located in the main body 3 of the mine 2 and knockout cartridge 4 at the end of the mine, designed to launch the mine from the mortar barrel (figa, b). A device, characterized in that instead of an explosive shell of a conventional mine, it uses a liquid deactivating chemical substance, and instead of a fuse, a “soft case”, for example, made of aluminum, is used.

Description of the principle of operation of the installation.

Charging mines with a decontaminant.

1. The liquid decontaminant 8 is poured into the empty main mine body 3.

2. The tip 5 is screwed by thread 6 into the main body 3, filled with liquid decontaminant 8. Launching a mine. The mortar is pointing at the object.

1. In the pre-launch position, the mine sinks into the mortar barrel.

2. After the collision of the mine with the striker, a blow occurs on the capsule of the expelling cartridge 4, ignition of the charge in the expelling cartridge and the launch of the mine from the mortar barrel.

3. After the landing of the mine, deformation and depressurization of the tip 5 occurs. As a result, the liquid deactivating chemical substance 8 is released from the main body 3 of the mine and gets into harmful chemicals. Next, the deactivating substance reacts with them.

Claims (1)

A device for the remote delivery of liquid deactivating substances to the site of destruction by harmful chemicals, including a mortar and a mine, containing a main body with a knockout cartridge, characterized in that the main body of the mine is equipped with a thread tip made of a material different from the material of the main body (for example, aluminum ), capable of deforming and, as a result, depressurizing the mine when it collides with an obstacle, while the internal cavity of the mine is filled with a liquid decontaminating substance.
