Description

The invention relates to the field of combat vehicles equipped with a hydropneumatic cleaning system for protective glass of a rangefinder sight.

It is known that (see Tank T-72 and its modifications. Operating Instructions. M .: Military Publishing House, 1991. - 272 p.) The hydropneumatic cleaning system consists of an air cylinder; pressure gauge; tap refueling system air; gearbox with filter; valve with tap; dispenser; a tank; water drain tap; nozzles; safety glass sight.

At the same time, to clear the protective glass from dirt, the gunner-operator must: open the cylinder valve 1; turn the handle of the valve tap 5 to a horizontal position until it stops; press briefly (for 1-2 seconds) until it stops against the start lever of the valve 5. Re-activation of the valve is possible after 2-3 seconds to ensure that the dispenser is filled with the next portion of liquid. When cleaning the glass with air only, the valve handle of the valve 5 must be installed in a vertical position until it stops and briefly press the valve lever.

The disadvantage of the presented system of hydropneumatic cleaning of the protective glass of the sight-rangefinder is that the gunner-operator performs a number of operations to clean the glass from dirt, which reduce the effectiveness of monitoring the battlefield and conducting aimed fire at enemy targets.

The objective of the present invention is to provide automation of the process of hydropneumatic cleaning of a protective glass sight-rangefinder.

This problem is solved by introducing into the well-known hydropneumatic cleaning system a microprocessor control unit, an LED, a photocell and a liquid level sensor.

At the same time, the hydropneumatic cleaning system of the protective glass of the sight-rangefinder, containing an air cylinder; pressure gauge; system filling valve; gearbox with filter; valve with tap; dispenser; tank; water drain tap; the nozzle, characterized in that the microprocessor control unit is additionally introduced, the inputs of which are electrically connected to the outputs of the photocell, liquid level sensor in the tank, air cylinder pressure gauge, and the output is electrically connected to the inputs of the LED and valve with a tap.

The invention is illustrated in the drawing.

The drawing shows a functional diagram of an automated system for hydropneumatic cleaning of protective glass sight-rangefinder, which includes the following elements: 1 - air cylinder; 2 - pressure gauge; 3 - tap for filling the system with air; 4 - gearbox with filter; 5 - valve with a tap; 6 - dispenser; 7 - tank; 8 - water drain valve; 9 - nozzle; 10 - protective glass sight; 11 - LED; 12 - photocell; 13 - microprocessor control unit; 14 - liquid level sensor.

Air cylinder 1 is intended for storage and supply of compressed air to the system.

The pressure gauge 2 is designed to control the air pressure in the cylinder and signal the presence of air in the cylinder to the microprocessor control unit.

The valve for filling the system with air 3 is designed to charge the cylinder with compressed air from the compressor unit.

The gearbox with filter 4 is designed to clean the air entering the system and its distribution.

A valve with a tap 5 is designed to supply air and liquid to the nozzle. It represents a modified design of the valve with a tap, allowing the supply of liquid or air to the nozzle, not only when the lever of the tap is pressed by the gunner-operator, but also by the signal from the microprocessor control unit.

The dispenser 6 is designed for uniform flow of fluid into the valve with a tap.

Tank 7 is designed to store liquid.

The water drain valve 8 is designed to drain the liquid remaining after using a combat vehicle in the presence of negative temperatures.

Nozzle 9 is designed to supply liquid and air to the protective glass of the rangefinder sight.

LED 11 is designed to supply a light signal to a photocell located inside the sight housing. It is an LED capable of delivering a narrow beam of light in a specific spectrum.

Photocell 12 is designed to receive a light signal from an LED and provide a signal about the presence or absence of an LED light signal to a microprocessor control unit.

The microprocessor control unit 13 is designed to form a command and provide a command for providing a light signal with an LED, analyze incoming signals from an air cylinder pressure gauge, a liquid level sensor, a photocell and supply a control signal to a valve with a crane.

The liquid level sensor in the tank 14 is designed to monitor the presence of liquid in the tank and to provide a signal about this to the microprocessor control unit.

Operation of the device: during operation of the hydropneumatic cleaning system for the safety glass of the sight-range finder, the LED 11 sends a light signal through the protective glass 10 to the photocell 12 at certain intervals, in accordance with the control command of the microprocessor control unit 13. With a clear protective glass 10, the light signal is transmitted to a photocell 12, which gives a signal about the presence of a light signal from the LED 11 to the microprocessor control unit 13. In this case, the cleaning of the protective glass 10 does not occur. In the case where the surface of the protective glass 10 is covered with dirt, a layer of dust, etc., which impede the passage of the light signal from the LED 11 through the protective glass 10 to the photocell 12, a signal is received from the photocell 12 to the microprocessor control unit 13 to stop the light signal from the LED 11 through the protective glass 10 to the photocell 12. Also, the microprocessor control unit 13 receives signals from the pressure gauge of the air cylinder 2 and the liquid level sensor in the tank 14. As a result of the information received in the micro The processor control unit generates a control signal, which is fed to a valve with a crane 5 and, in accordance with the cleaning function previously selected by the gunner-operator, either air or liquid is supplied with air or liquid through the nozzle 9 of the sighting rangefinder 10, thereby cleaning the protective glass rangefinder sight 10 from dirt, dust, snow. Therefore, depending on the contamination of the protective glass, the system automatically performs its cleaning without the intervention of a gunner-operator.

Thus, the proposed automated system for hydropneumatic cleaning of the protective glass of the sight-range finder allows automating the process of cleaning the protective glass of the sight-range finder as compared to the prototype, which positively affects the performance by the gunner-operator of the combat vehicle of his immediate duties and combat missions in general.
