[0044] See also Figure 1-6 The present invention provides a technical solution: a water curtain device for preventing infrared detection, comprising:

[0045] A housing 1, wherein a transmission hole 2 is provided at the bottom of the housing 1, and a curtain unit 3 is provided inside the housing 1;

[0046] A water spray pipe unit 4, which is installed on the housing 1;

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

[0048] The curtain unit 3 comprises 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 sleeved on the rotating shaft 32. The curtain is unfolded and folded by driving the rotating shaft to rotate by the motor.

[0049] The tail of the water storage plate 5 is bent to form a guide plate 7, and the guide plate 7 is located above the tensioning structure 6. The guide plate is just in contact with the curtain, forming a water storage tank with the curtain, ensuring that the water flows just to the curtain, and can also achieve the purpose of saving energy through the water storage tank.

[0050] The tensioning structure 6 includes a plurality of connectors 8 and a plurality of tensioning shafts 9, two of the connectors 8 are connected to the two ends of the plurality of tensioning shafts 9, a tensioning groove 10 is provided between the plurality of tensioning shafts 9, and the curtain 33 passes through the guide plate 7 and the tensioning groove 10 through the transmission hole 2 and extends to the outside of the housing 1. The connector at one end is connected to a micro motor, and the connector can be driven to rotate by the micro motor, thereby adjusting the inclination angle of the tensioning groove to achieve adjustment of the curtain tension.

[0051] The housing 1 is provided with a limiting hole 11, and the connector 8 is connected to the limiting hole 11 to ensure the stability of the tensioning structure connection.

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

[0053] The inner wall of the housing 1 is provided with a support plate 13, the support plate 13 is provided with a first mounting hole 14 and a second mounting hole 15, the motor 31 is located in the first mounting hole 14, the motor 31 is provided with a control line 16, the water pipe 41 is located in the second mounting hole 15 and extends through the housing 1 to be connected to a quick connector, and the quick connector is connected to a solenoid valve.

[0054] A windproof stopper 17 is provided at the bottom of the curtain 33, and the width of the windproof stopper 17 is greater than the width of the transmission hole 2. This prevents the bottom of the curtain from entering the housing and being difficult to take out, and also increases the force on the curtain, thereby achieving a windproof effect.

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

[0056] Working principle: By setting a curtain unit and a water sprinkler pipe unit in the outer shell, using the curtain unit as a carrier, the water sprinkler pipe unit is controlled by a solenoid valve. When defense is needed, just open the solenoid valve to allow water to flow through the spray hole to the curtain. The curtain will fall vertically downward under the influence of gravity, and the water will slowly flow downward along the curtain. When the water evaporates, it forms water mist, forming a water curtain on the curtain. The water curtain absorbs, scatters and reflects infrared radiation to achieve interference and shielding of infrared signals. In the field of civil air defense, the water curtain device can be used in combination with protective doors, windows, etc. to form an invisible infrared shielding barrier, which effectively blocks the line of sight of enemy infrared detection equipment and protects the safety of important facilities and personnel.
