Description

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

The closest in technical essence and the achieved technical result to the claimed hydrotrainer is a hydraulic simulator for training tank crews with a dehumidification device (Patent No. 190814 IPC G09B 9/00, B63C 11/32 publ. 12.07.2019, bull. No. 20), consisting of air discharge valve, air discharge pipe, flooded tank, kingston wells, upper tank, air supply valve, air supply pipe, piston internal combustion engine, centrifugal drive supercharger, lower tank, illu minator and dehumidifier.

A disadvantage of the known training simulator for training tank crews with a dehumidification device is the insufficient efficiency of dehumidifying indoor air only due to the condensation dehumidification proposed in the prototype. It is known that in order to establish the correct balance of humidity in the room in which there is a pool, there are two main ways:

the first is the assimilation of moisture by outside air;

the second is condensation drainage.

The first method is carried out directly using an exhaust and supply ventilation system, that is, moist air is replaced with fresh air from the street. The second method consists in removing moisture from the air, converting it to condensate, or in another way, drying the air, which was proposed by the authors of the above prototype. At the same time, in rooms with large volumes of water, it is advisable to use both of these methods to increase the efficiency of air drying.

The technical result of the proposal is to increase the efficiency of the drainage facilities of the gym.

The technical result is achieved through the organization of exhaust ventilation using a gas-air ejector connected to the exhaust pipe and functioning due to the energy of the exhaust gases of a reciprocating internal combustion engine.

The proposal is illustrated in the figure, which shows a diagram of a training simulator for training tank crews with a dehumidification device and forced ventilation.

The claimed training simulator for training tank crews with a dehumidification device and forced ventilation contains (Fig. 1) a hot heat exchanger 1, a fan with an electric motor 2, a cold heat exchanger 3, a vortex tube 4, an emergency air release valve 5, an air discharge valve 6, an air discharge pneumatic pipe 7, flooded tank 8, kingston wells 9, upper tank 10, air supply valve 11, air supply pneumatic pipe 12, reciprocating internal combustion engine 13, centrifugal drive supercharger 14, porthole 15, bottom ny tank 16, the exhaust pipe 17 connected to the ejector 18 and the exhaust pipe 19.

The proposed hydraulic simulator for training tank crews with a device for air drainage and forced ventilation works as follows.

The trained crew descends into the drained upper tank 10 and takes up space in the tank 8. The training leader starts the piston internal combustion engine 13. The standard drive centrifugal supercharger 14 of the piston internal combustion engine 13, which is driven by the crankshaft, delivers compressed air to the air supply 12 At this moment, the air supply valve 11 is open, and the air discharge valve 6 is closed. Compressed air acts on the surface of the water in the lower reservoir 15, as a result of which water rises through the Kingston wells 9, filling the upper reservoir 10 and flooding the tank 8. Having set the desired height of the water column in the upper reservoir 10, the air supply valve 11 closes and the piston internal combustion engine 13 stops. The crew is working on evacuation issues from the tank 8. Control over the work of the crew is carried out through the porthole 15.

The energy of the exhaust gases of the reciprocating internal combustion engine 13 is used as an ejection stream to provide exhaust ventilation of the room of the gym. The exhaust gases of the reciprocating internal combustion engine 13 under pressure enter the exhaust pipe 17. Since the gas-air ejector 18 is connected at one end to the exhaust pipe 17, and the second is connected to the exhaust pipe 19, the vacuum created in it by the exhaust gases allows the suction of moist air to be created through the exhaust pipe 19. The moist air pumped through the exhaust pipe 19, which condenses near the ceiling of the room, is mixed with the exhaust gases of the reciprocating internal combustion engine 13 and through yhlopnoy line 17 is released into the environment.

During classes with tank crews, the upper tank 10 is cycled filling and draining. When the upper tank 10 is drained, the air vent valve 6 opens and the overpressure in the lower tank 10 is vented to the atmosphere through the pneumatic vent line 7. Moreover, compressed air passing through the pneumatic vent line 7 is directed into the vortex tube 4 where, under the influence of the Ranke-Hills effect, it is divided into a heated (solid arrow) and a cooled stream (dashed arrow). Next, the cooled stream enters the cold heat exchanger 3, and the hot stream into the hot heat exchanger 1. Under the action of an electric motor with a fan 2, moist air is pumped sequentially first through the cold heat exchanger 3, then through the hot heat exchanger 1, as a result, air is drained in the room of the training simulator for crew training tank. After passing through the heat exchangers, the discharged air is discharged into the environment.

In the event of an emergency, when the upper tank 10 is filled with water, the life and health of the trained crew are in danger, an emergency air release valve 5 opens and excess pressure in the lower tank 10 is vented to the atmosphere through the air discharge pipe 7 bypassing the vortex tube 4. In this case, drainage the upper tank 10 is somewhat faster.
