Description

The proposal relates to the field of diving equipment, namely, training devices for testing training tasks for evacuating a tank stuck under water while overcoming water obstacles, crew adaptation to hydrostatic pressure and can be used in training centers of the Ground Forces of the Russian Federation.

The closest in technical essence and the achieved technical result to the declared hydraulic simulator for training crews of a tank with an air dehumidification device is a hydrotrener device (Patent No. 158688 IPC В63С 11/32, G09B 9/00, publ. 01/20/2016, bul. No. 2), consisting of an air discharge valve, an air vent pipe, a flooded tank, a Kingston well, an upper tank, an air supply valve, an air pneumatic line, a piston internal combustion engine, a centrifugal drive supercharger, a lower p reservoir of, porthole.

The disadvantage of the known hydrotuning device is that in the room in which it is used, the humidity indicator significantly exceeds the allowable values (up to 40-60% Sanitary rules and norms 2.2.4.2821-10 "Sanitary-epidemiological requirements for the conditions and organization of training in educational institutions "). The increased humidity in the premises has a negative impact both on the health of students, staff, and on the resource of the hydro-training device itself, accelerating its corrosive wear.

The technical result of the proposal is to reduce high humidity in the premises of a hydraulic trainer for training tank crews.

The technical result is achieved due to the installation of a dehumidifier at the exit from the pneumatic duct of air discharge consisting of a Ranke-Hilsch vortex tube (Merkulov, AP Vortex effect and its use in engineering / AP Merkulov. - Samara: Optima, 1997. - 184 pp.) Supplying the separated discharged air streams to the hot and cold heat exchangers, while the air is circulated by a fan with an electric motor, and the air line of the air vents is equipped with an emergency air relief valve.

The proposal is illustrated in the figure, which shows a diagram of a hydraulic train with an air dehumidification device.

Declared a hydraulic simulator with a dehumidification device contains a hot heat exchanger 1, a fan with an electric motor 2, a cold heat exchanger 3, a vortex tube 4, an emergency air relief valve 5, an air discharge valve 6, an air discharge pneumatic line 7, king-wells 8, an upper reservoir 9, a valve air supply 10, air supply line 11, piston internal combustion engine 12, drive centrifugal supercharger 13, lower reservoir 14, porthole 15.

The proposed flow simulator with a dehumidification device works as follows.

The trained crew descends into the drained upper reservoir 9. The training head starts a piston internal combustion engine 12. A regular drive centrifugal supercharger 13 of a piston internal combustion engine 12, driven by a crankshaft, delivers compressed air to the air supply air duct 11. At this moment, the supply valve air 10 is open, and the air discharge valve 6 is closed. Compressed air acts on the surface of the water in the lower reservoir 14, as a result of which the water rises through the Kingston wells 9, filling the upper tank 9. Setting the desired height of the water column in the upper tank 9, the air supply valve 10 closes and the piston internal combustion engine 12 stops. The crew is engaged in the development of training issues. Control over the work of the crew through porthole 15.

During classes with crews, the upper tank 9 is cyclically filled and dried. When the upper tank 9 is dehumidified, the air discharge valve 6 opens and the overpressure in the lower tank 9 is vented to the atmosphere through the air discharge pneumatic line 7. Moreover, the compressed air is passed through the air discharge pneumatic line 7 into the vortex tube 4 where, under the action of the Ranke-Hilsch effect, it is divided into a heated (solid arrow) and cooled stream (dashed arrow). Next, the cooled stream enters the cold heat exchanger 3, and the hot flow into the hot heat exchanger 1. Under the action of an electric motor with a fan 2, humid air is pumped sequentially first through the cold heat exchanger 3, then through the hot heat exchanger 1, as a result, the air in the hydraulic train is dried. After passing through the heat exchangers, the discharged air is discharged into the environment.

In the event of an emergency situation, when the upper reservoir 9 filled with water is threatened, the emergency air relief valve 5 opens and the life and health of the trained crew and the overpressure in the lower reservoir 9 is vented to the atmosphere through the air vent pipe 7 bypassing the vortex tube 4. In this case, drainage upper tank 9 is somewhat faster.
