Description

The utility model relates to the field of diving technology, namely to training devices for practicing training tasks for evacuation from a tank stuck under water when overcoming a water barrier, adaptation of the crew to hydrostatic pressure, and can be used in training centers of the Ground Forces of the Russian Federation.

A hydraulic simulator with an ejection air drying device is known from the prior art (Patent No. 208206 IPC G09B 9/00, B63C 11/32, publ. air vent and air vent valve installed in the air vent line, kingstone wells, upper and lower tanks, air supply valve installed in the air supply line, reciprocating internal combustion engine with a driven centrifugal supercharger and a porthole, gas-air ejector, active flow inlet with using a branch pipe, it is connected to the outlets of hot and cold heat exchangers, which ensures the creation of a vacuum, due to which the dried air is sucked into the passive flow inlet.

The disadvantage of the known hydraulic simulator is the inability to maintain the required level of humidity in the room in which the hydraulic simulator is operated, due to the lack of regulation of the performance of the vortex tube and the ejector.

The closest in technical essence and achieved technical result to the claimed hydrosimulator is a hydrosimulator with an air drying device (Patent No. 190814 IPC B63C 11/32, G09B 9/00, publ. heat exchanger, fan with electric motor, vortex tube, emergency air release valve, air release valve, air release pneumatic line, kingston wells, upper and lower tanks, air supply valve, air supply pneumatic line, reciprocating internal combustion engine, driven centrifugal supercharger and porthole.

The disadvantage of the known hydraulic simulator with an air drying device is its low efficiency, due to the inability to maintain the required level of humidity in the room in which the hydraulic simulator is operated, due to the inability to control the performance of the fan and vortex tube.

The technical result of the proposal is to increase the efficiency of the hydraulic simulator by providing the ability to maintain the required level of humidity in the room in which it is operated.

The technical result is achieved through the use of a device for controlling the level of air drying, which includes a rack and pinion gear, a stepper motor and a reduction gear, the rack and pinion gear consists of a spur gear and a rod in the form of a round gear rack, made in one with a throttle made with the ability to move inside the body of the vortex tube by means of a rack and pinion, the stepper motor is configured to transfer force to the rack and pinion by means of a reduction gear, the control unit, depending on the indicator of the humidity sensor, is configured to generate a signal to the stepper motor.

The proposal is illustrated by drawings, where:

in fig. 1 shows a schematic diagram of a hydro simulator for training tank crews with a device for controlling the level of air drying;

in fig. 2 is a schematic diagram of a device for controlling the level of air dehumidification.

The proposed hydraulic simulator contains a hot heat exchanger 1, a fan with an electric motor 2, an electronic control unit 3 with a humidity sensor, a cold heat exchanger 4, a vortex tube 5 with a throttle 6 and with a device for controlling the level of air dehumidification 7, an emergency air vent valve 8, an air vent valve 9, pneumatic air discharge line 10, kingstone wells 11, upper tank 12, air supply valve 13, air supply pneumatic line 14, reciprocating internal combustion engine 15, drive centrifugal blower 16, lower tank 17, porthole 18.

The air dehumidification level control device 7 (see Fig. 2) consists of a rod 19, made in the form of a round gear rack, made integral with the throttle 6 of the vortex tube 5, a reduction gear 20, a spur gear 21, which is engaged with the rod 19, forming a rack and pinion gear, a stepper motor 21, located in the same housing 23 with a reduction gear 20.

The proposed hydraulic simulator for training tank crews with a device for controlling the level of air drying works as follows.

The trained crew descends into the drained upper tank 12. The training leader starts the piston internal combustion engine 15. The standard drive centrifugal supercharger 16 of the piston internal combustion engine 15, driven by the crankshaft, supplies compressed air to the pneumatic air supply line 14. At this moment, the supply valve air 13 is open and the air release valve 9 is closed. Compressed air acts on the surface of the water in the lower tank 17, as a result of which the water rises through the wells-kingstons 11, filling the upper tank 12. Having set the desired height of the water column in the upper tank 12, the air supply valve 9 closes and the piston internal combustion engine 15 stops. The crew is working on training issues. Control over the work of the crew is carried out through the porthole 18.

When carrying out classes with crews, the upper tank 12 is cyclically filled and drained. When the upper tank 12 is drained, the air release valve 9 opens and the excess pressure in the lower tank 15 is vented to the atmosphere through the air release pneumatic line 10. Moreover, passing through the air release pneumatic line 10, compressed the air is directed into the vortex tube 5, where, under the action of the Ranke-Hilsch effect, it is divided into a heated (solid arrow) and a cooled flow (dashed arrow). Further, the cooled flow enters the cold heat exchanger 3, and the hot flow enters 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 hydro-trainer room is dehumidified.

Regulation of the required level of humidity in the room in which the hydraulic simulator is operated is carried out as follows. The operator of the hydraulic simulator sets the required humidity values in the room, which are processed in the electronic control unit 3, connected by electric cables to a fan with an electric motor and a device for controlling the level of air dehumidification 7. Further, the electronic control unit 3, depending on the readings of the humidity sensor, generates a signal coming through two channels control: through the first control channel to the fan with electric motor 2, ensuring its required performance; through the second channel to the device for controlling the level of air drying 7. The corresponding signal is sent to the stepper motor 22, the rotor of which rotates at a certain angle. The torque from the rotor of the stepper motor 22 by means of a reduction gear 20, which increases the torque at the output of it, is transmitted to a rack and pinion gear, consisting of a spur gear 21 and a rod 19. The rotational movement of the spur gear 21 is converted into the translational movement of the rod 16, which , in turn, moves the throttle 6 of the vortex tube 5 by the required amount, which allows, by changing the flow area between the body of the vortex tube and the throttle 6, to control the overall pressure level in the vortex tube 5, and consequently, the temperature in the hot 1 and cold heat exchangers 4 (Merkulov A.P. Vortex effect and its application in technology / A.P. Merkulov. - Samara: Optima, 1997. - 184 p.).

Thus, a two-channel regulation of the humidity level in the room in which the hydraulic simulator is operated is carried out.

After passing through the heat exchangers, the discharged air is discharged into the environment.

Compared with the prototype, the proposed device makes it possible to maintain the required level of humidity in the room in which the hydraulic simulator is operated.
