Description

Technical Field

[0001] The present invention relates to the technical field of sights, and in particular to a non-contact sight cleaning device. Background Art

[0002] With the rapid development of information technology, military combat equipment is also rapidly being upgraded. Sights play a vital role in various wheeled and tracked combat vehicles, including patrol and reconnaissance, fire strikes, and combat command. However, combat vehicles often need to navigate harsh environments such as mud, smoke, sand, and potholes. Sight windows are easily contaminated by mud and dust, seriously affecting their combat performance or even completely rendering them inoperable.

[0003] To address this situation, existing treatment methods generally include scraping with a scraper, blowing with compressed air, or manual cleaning.

[0004] Scraping with a wiper blade typically involves using a motor-driven reciprocating mechanism with wiper blades mounted on it to clean the sight window. However, this method is only suitable for sights with lower precision requirements and can easily damage the window, especially when scraping mud and sand, which can easily scratch the window surface. For high-precision sights, contact scraping is often prohibited to prevent damage to the sight surface coating, which could result in significant financial losses.

[0005] Compressed air purging is a method for cleaning sights. A high-pressure gas tank is typically placed on the equipment, storing a constant amount of high-pressure air. When the purge is activated, the high-pressure air is ejected through a nozzle to clean the sight. This method eliminates direct contact with the sight, effectively protecting the sight window's accuracy. However, it suffers from short battery life and poor cleaning performance. After several uses, the internal pressure of the gas tank decreases, causing the system to fail, requiring specialized equipment to replenish the high-pressure air, making it unsuitable for continuous operation. Furthermore, compressed air alone is often ineffective in removing solidified sediment. Summary of the Invention

[0029] See Figure 1 and Figure 2This embodiment discloses a non-contact sight cleaning device, including a water tank 1, a pressurizing structure 2, an air tank 3, a first solenoid valve 4, a second solenoid valve 5, and a nozzle 6. The output end of the water tank 1 is connected to the nozzle 6 through the pressurizing structure 2. The output end of the air tank 3 is divided into two, connected to the pressurizing structure 2 and the nozzle 6 respectively. The output end of the air tank 3 connected to the pressurizing structure 2 is provided with a first solenoid valve 4, and the output end of the air tank 3 connected to the nozzle 6 is provided with a second solenoid valve 5.

[0030] See Figure 3 The pressurizing structure 2 includes a pressurizing chamber 21 and a gravity valve 22. The pressurizing chamber 21 is provided with a water inlet 211, a water outlet 212 and an air inlet 213. The water inlet 211 is connected to the output end of the water tank 1 and is provided with a gravity valve 22. The water outlet 212 is connected to the nozzle 6, and the air inlet 213 is connected to the output end of the gas tank 3.

[0031] The first electromagnetic valve 4 and the second electromagnetic valve 5 are closed, the pressure chamber 21 loses pressure, the gravity valve 22 opens under the action of gravity, and the cleaning liquid in the water tank 1 begins to flow into the pressure chamber 21 until the pressure chamber 21 is full or the first electromagnetic valve 4 opens. Figure 4 As shown, the first solenoid valve 4 is opened, and the compressed air in the air tank 3 enters the pressurized chamber 21 through the air inlet 213, and the gravity valve 22 floats up and closes under the action of pressure, so that the pressurized chamber 21 is isolated from the water tank 1, and the high-pressure cleaning liquid in the pressurized chamber 21 is forced to enter the nozzle 6 through the water outlet 212 and spray out to clean the sight. After cleaning is completed, the first solenoid valve 4 is closed again, and the second solenoid valve 5 is opened at the same time. The compressed air blows the cleaned sight through the nozzle 6 to remove the water marks left on the sight window; this process not only does not require contact with the sight, preventing damage to the sight surface, but also the cleaning liquid is pressurized in the high-pressure chamber 21 and accelerated in the pipeline to form a jet with impact force, which can effectively remove dirt on the surface of the sight and improve the cleanliness of the sight cleaning device.

[0032] The water tank 1 is provided with a water inlet 11 on the top, and a water tank cover 12 is provided on the water inlet 11. A filter 13 is provided on the water inlet 11 for filtering the injected cleaning liquid.

[0033] A one-way valve 7 is further provided at the output end of the gas storage tank 3 , and a safety valve 8 is further provided on the gas storage tank 3 for overpressure protection.

[0034] The output end of the gas storage tank 3 is further provided with a pressurizing device 9. In this embodiment, the pressurizing device 9 is a compressor. A pressure switch 10 is also provided between the pressurizing device 9 and the output end of the gas storage tank 3. The pressurizing device 9 is used to regulate the pressure. When the compressed air pressure is lower than the lower limit of the regulation, the pressure switch 10 is turned on and the pressurizing device 9 starts to operate. When the compressed air pressure exceeds the upper limit of the regulation, the pressurizing device 9 stops.

[0035] Furthermore, the setting range of the pressure switch 10 is generally selected to be 0.6 to 1.0 MPa.

[0036] See also Figure 1 The nozzle 6 includes a base 61 and a nozzle body 62. The base 61 is provided with a rotatable nozzle body 62. The water outlet 212 of the pressurized chamber 21 and the output end of the gas tank 3 provided with the second solenoid valve 5 are both connected to the nozzle body 62.

[0037] Furthermore, the device includes a controller 100, which has a power supply input interface, a CAN bus communication interface, a pressure switch signal acquisition interface, a pressurizing device output interface, a first solenoid valve output interface, and a second solenoid valve output interface. The power supply input interface is used to connect to the device's main power supply; the CAN bus communication interface is used to connect to the equipment bus network, receive control instructions, and modify working parameters; the pressure switch signal acquisition interface is connected to the pressure switch 10, used to obtain the device pressure and provide a decision basis for the operation of the pressurizing device 9; the pressurizing device output interface is connected to the pressurizing device 9, and the device output interface is used to drive the pressurizing device 9 to rotate and generate compressed air; the first solenoid valve output interface is connected to the first solenoid valve 4, used to control the opening and closing of the first solenoid valve 4, thereby turning on and off the liquid spraying function of the device; the second solenoid valve output interface is connected to the second solenoid valve 5, used to control the opening and closing of the second solenoid valve 5, thereby turning on and off the jet purge function of the device.

[0038] The working principle of this embodiment is: the first solenoid valve 4 and the second solenoid valve 5 are turned off, the pressurized chamber 21 loses pressure, the gravity valve 22 opens under the action of gravity, and the cleaning liquid in the water tank 1 begins to flow into the pressurized chamber 21 until the pressurized chamber 21 is full or the first solenoid valve 4 is opened. The first solenoid valve 4 is opened, and the one-way valve 7 is automatically opened under the action of positive pressure. The compressed air in the air tank 3 enters the pressurized chamber 21 through the air inlet 213, and the gravity valve 22 floats up and closes under the action of pressure, so that the pressurized chamber 21 is isolated from the water tank 1, and the high-pressure cleaning liquid in the pressurized chamber 21 is forced to enter the nozzle 6 through the water outlet 212 and spray out to clean the sight. It should be noted that the cleaning process can continue the step-by-step spray cleaning, which can effectively remove solidified, large or large amounts of mud. Specifically, after the cleaning liquid in the pressurized chamber 21 is sprayed, the above steps are repeated for the next cleaning. Finally, after the cleaning is completed, the first solenoid valve 4 is closed and the second solenoid valve 5 is opened at the same time. The compressed air blows the cleaned sight through the nozzle 6 to remove the water marks left on the sight window.
