Description

The invention relates to the field of official dog breeding, and in particular to the field of training of service dogs, and can be used to train and smell dogs of dog training services used to search for explosives used by terrorists and members of illegal military units.

Recently, in connection with a significant increase in terrorist danger, the role of specially trained service dogs used for search activities has significantly increased.

The use of trained dogs for the detection of explosives is actively used worldwide by various services, as it allows inspection of buildings, premises, hand luggage, luggage, vehicles and cargo. The biggest advantage of the cynological service is its mobility and ability to work in unequipped rooms and field conditions, as well as the high sensitivity of dogs to the detection of explosives.

In order to teach a dog to detect explosives, it is necessary to train them using real explosives, which is associated with a great risk. In addition, it requires the use of special guarded storage facilities and landfills, accounting and control over the use of explosives as training information.

Known (Methodical recommendations “Use of odor simulators of explosives and explosive devices for training and training special dogs”, Rostov-on-Don, 1998) an explosive simulator for training dogs, which is a hollow aluminum cylinder with holes in the walls in which tissue is impregnated with a solution of RDX or TNT in an organic solvent

The disadvantage of this simulator is the low sorption capacity of the tissue, which makes it ineffective - first due to the impurity of the smell of the solvent, and then due to the decrease in the explosive content in the tissue (already low).

Known (RU, patent 2160528) is a composite simulator based on an odorologically inert material - a powder sorbent: microcrystalline cellulose, activated carbon, silica gel or polysorb, on the surface of which a polymolecular layer of explosives (TNT, hexogen, tetranitrate pentaerythritol (TEN), pore is applied the amount of not more than 5% by weight of the base, mainly 0.05-4.00%.

A significant disadvantage of the known simulator is the low content of explosives, which leads to a decrease in its effectiveness. In addition, the method of applying the multimolecular layer of explosives on the sorbent powder is not disclosed, which raises doubts about the feasibility of such a simulator.

Also known (S.I. Petrov. On the assessment of the possibility of detecting explosives and devices containing them. / Special chemistry, No. 4. 2001, p. 7 /) instructional details of explosives (TNT, RDX, PETN, smokeless pyroxylin powder, smokeless ballistic powder, nitrocellulose with nitroglycerin, nitrate), consisting of fabric bags with powder compositions containing the above compounds in quantities that are safe for the instructor and the dog and do not have explosive properties. They are placed in glass containers, which are installed in a packaging box.

Despite a number of positive characteristics, educational details have significant disadvantages:

- fabric bags burn and tear when working with a dog;

- absorb odors;

- the shelf life and operation does not exceed 3 months.

The closest analogue of the developed technical solution can be recognized (RU, patent 2315475) a composite explosive simulator for training search dogs based on an inert material containing an explosive substance, which is a solid body of any given shape, made by curing with water a homogeneous mixture of alabaster powder and explosive substance at the explosive content in the mixture is 5-10 wt.%.

A disadvantage of the known composite simulator is the presence of a significant amount of explosive inside the solid, which noticeably attenuates the target smell of the explosive needed to set the dog to smell. The disadvantages of the known simulator include the mechanical fragility of a solid made on the basis of alabaster, which leads to chipping of its pieces and an uncontrolled change in the content of odorological additives - explosives - in the simulator.

The technical problem solved by the developed invention is to create reliable equipment for training service dogs.

The technical result obtained by the implementation of the developed technical solution is to enable the dog to memorize the smell of tetrile in a stable manner.

To achieve the indicated technical material, it was proposed to use an odor simulator of explosive - tetrile for training service dogs containing a mixture of an inert carrier and a odorological substance, and a mixture containing octogen and trinitrotoluene was used as a odorological substance, while the mixture was placed in a breathable polymer container.

It was experimentally established that the presence of trinitrotoluene explosive odor in the simulator together with the octogen makes it easier for the dog to remember the smell of the target tetril explosive.

The quantitative composition of the simulator of the developed composition for the detection of explosives - tetryl can vary depending on age and experience, as well as the limit of detection of odor characteristic of each particular dog. In addition, the quantitative composition of the simulator is influenced by the stage of preparation of the service dog for work on the search for explosives of tetryl. In the first stages, when the service dog only remembers the smell of tetrile, the content of the odorological substance should be greater, as well as the content of HMX. With an increase in training time and with the memorization of this specific smell, a smaller amount of odorological substance with less octogen, and also with less trinitrotoluene, is used.

In a preferred embodiment, the implementation of the simulator of the developed composition and purpose, the content of HMX in the odorological substance is from 1 to 5% of the mass. by weight of the simulator, as well as the content of trinitrotoluene.

A container in which a mixture of an inert carrier and odorological substance is placed is a bag or box. The transmission of air as a carrier of the target odor is provided using the appropriate material (low-pressure polymer film) or a system of holes made with the possibility of preventing the spill of a mixture of an inert carrier and odorological substance.

In some embodiments, the container may be made of polyethylene or polypropylene.

As an inert carrier, microcrystalline cellulose, silica gel, activated carbon, alumina, and other carriers having a finely porous structure can be used.

In the manufacture of the simulator, octogen and trinitrotoluene are mixed in the amounts selected depending on the task. The resulting mixture is mixed in any known manner with an inert carrier. The resulting tetryl simulator is placed in a breathable container and stored in an airtight container.

The following are examples of the implementation of the developed tetril odor simulator.
