Description

Technical Field

[0001] The utility model relates to the technical field of military camouflage, in particular to an adjustable anti-infrared radiation detection camouflage device. Background Technique

[0002] In the field of national defense, in the face of the reconnaissance of the enemy, a camouflage device is needed to hide the real military facilities and simulate fake military facilities to mislead the enemy's judgment. Infrared remote sensing is one of the important reconnaissance means. This method analyzes the infrared radiation signal and combines the shape of the military facilities and the infrared radiation characteristics of the materials. In order to hide the real military facilities, such as positions, artillery, fighter jets, and armored vehicles, the infrared radiation signal of the camouflage material needs to be consistent with the environment. If you want to simulate fake military facilities, the infrared radiation signal of the camouflage material needs to be similar to that of the real military facilities. The infrared radiation signal of military facilities also varies according to different working conditions. In order to pursue the flexibility of use, the camouflage material needs to dynamically simulate various infrared radiation signals of different intensities, so as to mislead the enemy.

[0003] Therefore, we design an adjustable anti-infrared radiation detection camouflage device here. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 6 , in this implementation: An adjustable anti-infrared radiation detection camouflage device includes a camouflage unit 1. The camouflage unit 1 includes a rectangular frame 1-1. Four equally spaced aluminum columns 1-2 are rotatably installed between the upper and lower horizontal plates of the rectangular frame 1-1. A graphite plate 1-6 is embedded in each aluminum column 1-2. A polyurethane plate 1-3 and a copper plate 1-4 are installed inside the rectangular frame 1-1. The aluminum columns 1-2 are sandwiched between the polyurethane plate 1-3 and the copper plate 1-4. The space between the polyurethane plate 1-3 and the copper plate 1-4 is filled with polystyrene foam plastic 1-5. The infrared emissivity of the aluminum columns 1-2 is relatively low, and the external emissivity material of the graphite plate 1-6 is relatively high. The surface where the polyurethane plate 1-3 is located is the front of the camouflage unit 1, and the surface where the copper plate 1-4 is located is the back of the camouflage unit 1.

[0021] Please refer to Figure 2 and Figure 3 , when the aluminum column 1-2 rotates to make the graphite plate 1-6 parallel to the front of the camouflage unit 1, the aluminum with low infrared emissivity faces the front. At this time, when viewed from the front, the external infrared radiation signal of the camouflage unit 1 is the weakest. When the aluminum column 1-2 rotates to make the graphite plate 1-6 perpendicular to the front of the camouflage unit 1, the area of the graphite plate 1-6 in the middle of the aluminum column 1-2 facing the front of the camouflage unit 1 is the largest. At this time, when viewed from the front, the external infrared radiation signal of the camouflage unit 1 is the strongest. By controlling the rotation of the aluminum column 1-2, the strength of the external infrared radiation signal of the camouflage unit 1 can be adjusted.

[0022] The polyurethane plate 1-3 serves to protect the aluminum column 1-2 and transmit infrared signals. The function of the polystyrene foam plastic 1-5 is to isolate the heat transmitted from the object below the camouflage unit 1. When the camouflage unit 1 needs to provide strong infrared radiation, the copper plate 1-4 can directly obtain heat from the object below. When the temperature of the object below is not high itself, the copper plate 1-4 can obtain heat by means of electric heating. In this way, the radiation unit 1 can obtain a large adjustable range of infrared radiation.

[0023] Please refer to Figure 4 and Figure 5, a cylindrical concave hole is provided on the top surface of the upper cross plate of the rectangular frame 1-1. The cylindrical concave hole is directly above the leftmost aluminum column 1-2. A knob 1-7 is arranged in the cylindrical concave hole. The height of the knob 1-7 is less than the depth of the cylindrical concave hole on the rectangular frame 1-1. The end of the top rotating shaft of the leftmost aluminum column 1-2 passes through the rectangular frame 1-1 and is fixed to the knob 1-7 in the cylindrical concave hole. A cavity is arranged in the lower cross plate of the rectangular frame 1-1. The end of the bottom rotating shaft of the four aluminum columns 1-2 all penetrate to the cavity of the lower cross plate and are installed with first gears 1-8. Three second gears 1-9 are rotatably installed in the cavity of the lower cross plate. The three second gears 1-9 are respectively arranged between two adjacent first gears 1-8 and are simultaneously meshed with these two first gears 1-8. By rotating the knob 1-7, the leftmost aluminum column 1-2 can be controlled to rotate. Then, through the transmission of all the first gears 1-8 and all the second gears 1-9, the other three aluminum columns 1-2 can be controlled to rotate together with the leftmost aluminum column 1-2.

[0024] Please refer to Figure 1 and Figure 6 , the adjustable anti-infrared radiation detection camouflage device further includes a connecting member 2. The connecting member 2 is composed of a hinge 2-1 and two plug plates 2-2. The two plug plates 2-2 are respectively installed on the fronts of the two folding plates of the hinge 2-1. Slots 1-10 are arranged around the outside of the rectangular frame 1-1. The plug plates 2-2 can be inserted into the slots 1-10. Multiple camouflage units 1 can be assembled by the connecting member 2 to form a certain area.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
