[0002] With the rapid development of modern military technology, infrared detection technology has become increasingly widespread and deeply applied in the military field, providing unprecedented monitoring and tracking capabilities for military operations. Advanced infrared detection equipment, such as infrared thermal imagers, leverages their unique advantage of passively receiving the infrared thermal radiation of targets to achieve precise monitoring and tracking day and night, greatly enhancing the stealth and accuracy of military operations. However, the widespread application of this technology also poses unprecedented and severe challenges to military defense systems.

[0003] With the continuous advancement of infrared detection technology, its performance indicators such as detection range, resolution, and sensitivity are constantly improving, further enhancing the stealth and surprise of military operations. How to effectively hide or disguise heat sources to avoid detection by infrared detection equipment has become a pressing issue. Currently, infrared shielding equipment is used to interfere with or block the normal operation of infrared detection equipment through specific technical means, thereby reducing its detection effectiveness. However, some traditional shielding methods cannot completely cover all bands of infrared radiation, resulting in some infrared detection equipment still functioning normally. Furthermore, with the continuous advancement of infrared detection technology, some new infrared detection equipment has acquired stronger anti-interference capabilities, rendering traditional shielding methods gradually ineffective and unable to achieve the purpose of military defense.

[0026] 1. In this utility model, a curtain unit and a water spray pipe unit are set inside the outer shell. The curtain unit serves as the carrier, and the water spray pipe unit is controlled by an electromagnetic valve. When defense is required, the electromagnetic valve is turned on, allowing water to flow through the spray holes onto the curtain. The curtain will hang vertically downwards due to gravity, and the water will flow slowly downwards along the curtain. As the water evaporates, it forms a water mist, creating a water curtain on the curtain. The water curtain absorbs, scatters, and reflects infrared radiation, thereby interfering with and shielding infrared signals.

[0044] Please see Figure 1-6 This utility model provides a technical solution: a water curtain device for preventing infrared detection, comprising:

[0045] The outer casing 1 has a transmission hole 2 at its bottom and a screen unit 3 inside the outer casing 1.

[0046] Water spray pipe unit 4, which is mounted on the outer casing 1;

[0047] The water storage plate 5 is installed obliquely on the inner wall of the housing 1 and located at the bottom of the water spray pipe unit 4. The curtain unit 3 extends through the transmission hole 2 to the outside of the housing 1 via the water storage plate 5 and the tensioning structure 6.

[0048] The curtain unit 3 includes a motor 31, a rotating shaft 32, and a curtain 33. The motor 31 is connected to the rotating shaft 32, and the curtain 33 is fitted onto the rotating shaft 32. The curtain is unfolded and retracted by driving the rotating shaft to rotate.

[0049] The water storage plate 5 is bent at its tail to form a guide plate 7, which is located above the tensioning structure 6. This allows the guide plate to abut against the screen, forming a water storage tank with the screen. This ensures that the water flows directly to the screen while also saving energy through the water storage tank.

[0050] The tensioning structure 6 includes several connectors 8 and several tensioning shafts 9. Two connectors 8 are connected to the two ends of the tensioning shafts 9. Tensioning grooves 10 are provided between the tensioning shafts 9. The curtain 33 passes through the guide plate 7 and the tensioning grooves 10, passes through the transmission hole 2, and extends to the outside of the outer shell 1. One end of the connector is connected to a micro motor, which can drive the connector to rotate, thereby adjusting the tilt angle of the tensioning groove and adjusting the tension of the curtain.

[0051] The outer casing 1 is provided with a limiting hole 11, and the connector 8 is connected to the limiting hole 11. This ensures the stability of the tension structure connection.

[0052] The water spray pipe unit 4 includes a water pipe 41, and a plurality of spray holes 12 are provided at the bottom of the water pipe 41. The plurality of spray holes 12 are located above the water storage plate 5. This ensures that the spray holes guide water into the water storage tank and then flow to the curtain, forming a water curtain on the curtain.

[0053] A support plate 13 is provided on the inner wall of the outer casing 1. The support plate 13 has a first mounting hole 14 and a second mounting hole 15. The motor 31 is located in the first mounting hole 14 and has a control line 16. The water pipe 41 is located in the second mounting hole 15 and extends through the outer casing 1 to connect to a quick connector. The quick connector is connected to a solenoid valve. The solenoid valve controls the water flow through the water pipe. The entire structure is securely connected, improving the service life of the device.

[0054] The bottom of the screen 33 is provided with a windproof limiting member 17, the width of which is greater than the width of the transmission hole 2. This prevents the bottom of the screen from getting into the outer casing and making it difficult to remove, while also increasing the stress on the screen and achieving the function of wind protection.

[0055] The water storage plate 5 and the curtain 33 form a V-shaped water storage tank 18. When the water flow velocity is greater than the downstream velocity, a water storage tank will be formed at the angle, which will suppress the water flow velocity to a certain extent, thereby saving energy and reducing the cost of use.

[0056] Working principle: By setting up a curtain unit and a water spray pipe unit inside the outer casing, using the curtain unit as the carrier, and the water spray pipe unit controlled by an electromagnetic valve, when defense is needed, simply open the electromagnetic valve to allow water to flow through the spray holes onto the curtain. The curtain will be vertically downward due to gravity, and the water will slowly flow down the curtain. When the water evaporates, it forms a water mist, creating a water curtain on the curtain. By utilizing the absorption, scattering, and reflection of infrared radiation by the water curtain, it can interfere with and shield infrared signals. In the field of civil defense, the water curtain device can be used in conjunction with protective doors, windows, etc., to form an invisible infrared shielding barrier, effectively blocking the line of sight of enemy infrared detection equipment and protecting the safety of important facilities and personnel.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
