Description

The invention relates to the field of mechanical engineering, namely to means of protection against weapons of mass destruction and can be used for degassing, decontamination and disinfection of armored weapons and equipment.

A tank degassing kit TDP is known (Tank degassing kit (TDP Set). Technical description, operating instructions and passport: Military Publishing House of the Ministry of Defense of the USSR, 1970. - P. 38 ) consisting of two autonomous TDP devices, a charging device, 4 clamps , funnels and spare accessories.

The disadvantage of this tank degassing kit is that to charge autonomous devices, air is used from the cylinders of the tank’s air system, which is the main system for starting the engine of a combat vehicle, which indicates the negative impact of this design on the combat readiness of the tank.

Also known from the prior art is a vehicle kit for special processing of military equipment DK-4 and its modifications (“Vehicle kit for special processing of military equipment DK-4”). Technical description, operating instructions and passport" M.: Military Publishing House of the Ministry of Defense of the USSR, 1969. - P. 60), consisting of the main power plant of the sample being processed, a gas sampling device, a jet ejector, liquid and gas-liquid hoses, a fire hose with an extension and a brush .

Lack of the Known automotive kit for special processing of military equipment DK-4 consists is that its use requires the operation of the main power plant of the sample. The operation of the main power plant during the processing of the vehicle leads to unproductive fuel consumption, reducing its power reserve, as well as increasing the visibility of the sample in the thermal spectrum, making it detectable by enemy fire weapons.

The solution to this problem was found in a device for the decontamination of armored weapons and equipment (APTV) that is closest in technical essence and achieved technical result to the declared one (RF utility model No. 192107 / D.V. Shabalin, A.Yu. Sergeev, A.D. . Dmitriev et al. Published 09/04/2019), consisting of an auxiliary power unit (APU) of the sample, a gas sampling device with a vortex ejector equipped with a diffuser with a damper, a liquid hose with a valve, a gas-liquid hose, a fire hose, an extension cord and a brush.

The disadvantage of the prototype is in the low efficiency of decontamination of armored vehicles using the method of suctioning radioactive dust. This is due to the fact that the brush included in the kit does not provide sufficient effectiveness. Thus, when decontaminating a sample of armored vehicles by the method of suctioning radioactive dust when exposed to a brush on the dusty walls of the body (hull) of the object, most of it will rise into the air forming a dust cloud and fall to the ground, swept away by the lint of the brush, and only a small part will be sucked inside.

The technical result of the invention is to increase the efficiency of decontamination of armored vehicles using the method of suctioning radioactive dust.

The technical result is achieved by screwing a nozzle with through holes made on opposite sides between the extension and the brush using a threaded connection, above which metal screens are welded.

The proposal is illustrated by drawings, where:

in fig. 1 shows a general view of the proposed device;

in fig. Figure 2 shows an attachment device for increasing the efficiency of decontamination of armored weapons and equipment.

in fig. 3 shows a bottom view of the proposed device.

The device for decontamination of armored weapons and equipment contains an APU of sample 1, connected by a gas sampling device 2 to a vortex ejector 3, equipped with a diffuser 4 with a damper 5, while the liquid hose 6 is equipped with a valve 7, and the gas-liquid hose 8 is connected by a fire hose to an extension 9 and a brush 10 ( Fig.1, 3). Between the extension 9 and the brush 10, using a threaded connection, a nozzle 11 is screwed into which through holes 12 are made on its opposite sides, above which metal screens 13 in the shape of a hemisphere are welded (Fig. 2, 3).

The proposed device works as follows.

During decontamination by suctioning radioactive dust, valve 7 is closed and damper 5 of diffuser 4 is opened, the exhaust gases of the APU of sample 1 pass through the ejector 3 and are released into the atmosphere, while a vacuum is created in the gas-liquid hose 8. Under the influence of the mechanical action of the brush 10, the dust is torn off from the surface being treated, falls under the hemispherical screens 13 and then through the through holes 12 in the nozzle 11, bypassing the fire nozzle with extension 9, is sucked along the gas-liquid hose 8 into the ejector 3, from where it is released with a flow of gases through the diffuser 4 into a special bag.

Compared to the prototype, the proposed device can significantly increase the efficiency of decontamination of armored vehicles using the method of suctioning radioactive dust.
