Description

Technical Field

[0001] The invention relates to the technical field of camouflage equipment, in particular to a special-shaped camouflage net with optical radar infrared camouflage stealth functions. Background Art

[0002] With the rapid development of military science and technology and camouflage technology, the application of camouflage nets in modern warfare and national security has shown unprecedented depth and breadth. In the complex battlefield environment of the 21st century, camouflage nets are no longer just simple coverings of single colors and patterns, but have evolved into a tactical weapon that integrates high-tech and multi-spectrum camouflage characteristics. In today's products, in order to obtain camouflage nets with different performances, a variety of auxiliary materials are generally added to the camouflage nets to obtain camouflage nets for different application scenarios.

[0003] The structure of a conventional camouflage net is a skeleton net with one or two layers of cut net tied on the surface. The camouflage net is mainly made of polyester cloth, and may be coated with one or more layers of special coatings. These coatings can be reflective materials used to scatter radar waves and achieve radar stealth; they can also be materials that absorb infrared rays to reduce heat signals and resist infrared detection.

[0004] The existing camouflage net structure is shown in the Chinese patent "A basalt fiber blended cloth camouflage net" (application number CN202022729665.X, published on 20210813): A basalt fiber blended cloth camouflage net, including a surface layer and a bottom layer, the surface of the surface layer is cut, and a plurality of open cavities are formed between the surface layer and the bottom layer; as shown in the Chinese patent "A sandwich structure camouflage net and its preparation method" (application number CN202111185929.2, published on 20211224): The present invention relates to a A sandwich camouflage net and a preparation method thereof, wherein the sandwich camouflage net is made of a surface layer, an interlayer and a bottom layer through hemming and quilting, wherein the surface layer is made by coating flame retardant coating on both sides of a base cloth, drying it, coating absorbing coating on one side and drying it, then coating camouflage coating on both sides, and drying it to make camouflage monochrome cloth, and the camouflage monochrome cloth is made into the surface layer through jigsaw puzzle and flower cutting processes; the interlayer is made by impregnating mesh cloth with absorbing coating and drying it; the bottom layer is made by coating flame retardant coating on both sides of a base cloth, drying it, coating absorbing coating on one side and drying it, then coating infrared coating on both sides, and cutting holes.

[0005] The above-mentioned existing camouflage net has a multi-layer structure, and the surface layer structure is mostly coated with absorbing paint, and then cut and stretched to form a cavity to improve the absorbing effect. However, the existing camouflage net has a simple structure, and the cavity formed by cutting the surface layer alone cannot well improve the absorbing effect. In the process of combining the surface layer with other functional layers, the protrusions formed by cutting the surface layer will interfere with the other functional layers, thereby resulting in a reduction in the volume of the cavity formed by the surface layer, thereby affecting the absorbing effect of the camouflage net. Summary of the invention

[0006] The present invention is intended to provide a special-shaped camouflage net with optical radar infrared camouflage stealth function, which is mainly used to solve the technical problem in the prior art that when the surface layer of the camouflage net is combined with other functional layers, the protrusions formed by the surface layer cutting will interfere with the other functional layers, thereby resulting in a reduction in the volume of the cavity formed by the surface layer, thereby affecting the camouflage net's absorbing effect.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A special-shaped camouflage net with optical radar infrared camouflage stealth function includes a first absorbing layer and a second absorbing layer, both of which are coated with absorbing paint and have a surface cut-pattern treatment, and a separator for separating the first absorbing layer from the second absorbing layer is arranged between the first absorbing layer and the second absorbing layer.

[0009] Preferably, a side of the first absorbing layer away from the second absorbing layer is connected to a bottom net, and a separator is installed on a side of the first absorbing layer facing the bottom net.

[0010] Preferably, the partition comprises a plurality of flower clusters, the flower clusters comprise a plurality of cloth strips, the cloth strips comprise a free end and a fixed end, and the fixed ends of the plurality of cloth strips are fixed together.

[0011] Preferably, among the several cloth strips of the flower cluster, the free end of the cloth strip close to the center of the flower cluster is fixedly connected to the middle of the cloth strip away from the center of the flower cluster and arranged adjacently.

[0012] Preferably, the cloth strip is coated with an absorbing coating, and a metamaterial layer is attached to the cloth strip, and the metamaterial layer includes any one or more of a pet-ito metamaterial film, a metal mesh metamaterial film, and a graphene-based metamaterial film.

[0013] Preferably, the free end edge of the cloth strip is arranged in an arc shape.

[0014] Preferably, the cloth strip has a length of 26-46 mm and a width of 10 mm.

[0015] Preferably, the partitions are arranged at a density of 4-9 pieces / 1.44 m2.

[0016] Preferably, the first absorbing layer and / or the second absorbing layer is fixedly connected or detachably connected to the fixed end of the flower cluster.

[0017] Preferably, a mounting net is provided on the first absorbing layer and / or the second absorbing layer, and the mounting net comprises a plurality of mesh strips which are crisscrossed and coated with absorbing material for protection, and the first absorbing layer and / or the second absorbing layer are detachably or fixedly connected to the mounting net; the mounting net is fixedly or detachably connected to the fixed end of the flower cluster.

[0018] Beneficial effects:

[0019] 1. After the first absorbing layer and the second absorbing layer are coated with absorbing materials, they have absorbing properties, and after the first absorbing layer and the second absorbing layer are cut and stretched, a plurality of cavities can be formed on the surface. The separator separates the first absorbing layer and the second absorbing layer, which can reduce the deformation of the edges of the cavities on the first absorbing layer and the second absorbing layer due to mutual extrusion, and ensure that the reflection space in the cavity is sufficient. At the same time, the split component locally supports the first absorbing layer and the second absorbing layer, increases the spatial disorder between the first absorbing layer and the second absorbing layer, improves the absorbing performance, and enhances the optical radar infrared camouflage stealth performance of the entire special-shaped camouflage net. Compared with the prior art that simply superimposes the camouflage net with other functional layers, the design of this solution solves the technical problem that the camouflage net surface layer in the prior art is combined with other functional layers, and the bulges formed by the surface layer cutting will interfere with other functional layers, thereby resulting in a reduction in the volume of the cavity formed by the surface layer, thereby affecting the camouflage net.

[0020] 2. In this solution, the flower cluster is composed of several cloth strips. When the fixed ends of all the cloth strips are fixed together and fixed on the first absorbing layer or the second absorbing layer, the fixed ends of the cloth strips form a supporting force, so that all the cloth strips are in the shape of a "flower cluster" with one end gathered and the other end radiating, forming a spacing unit as a whole, separating the two absorbing layers with a point distribution; the cloth strips are light in weight and are coated with absorbing materials on both sides, so that the flower cluster as a whole has absorbing properties, and will not interfere with the absorbing properties of the entire special-shaped camouflage net. At the same time, the weight of the entire special-shaped camouflage net will not be greatly increased due to the addition of the flower cluster, which is convenient to carry and use.

[0021] 3. The mounting net is combined with the first absorbing layer and / or the second absorbing layer. On the one hand, it can ensure that the first absorbing layer or the second absorbing layer maintains the shape after stretching, and ensure that the cavity shape on the absorbing layer is fully expanded during use. On the other hand, when the absorbing layer is pulled, the mounting net can enhance the tensile strength of the absorbing layer.

[0022] 4. Fix the flower cluster on the installation net. You can change the number of flower clusters installed on the installation net to determine the separation effect of the partition on the two absorbing layers. Then install the installation net on the absorbing layer. The installation net with different partitions can be assembled with the absorbing layer according to the use requirements, which is convenient and quick.

[0023] 5. The free end of the cloth strip is fixed to the middle part of the adjacent outer cloth strip, so that an arch-shaped supporting space can be formed between the adjacent cloth strips. Without increasing the weight of the flower cluster, the separation effect of the flower cluster can be better achieved by only changing the shape of the cloth strip. At the same time, several cloth strips can be connected in this way to form a pagoda shape as a whole, which is not easy to get stuck in the gap formed after the absorbing layer is cut, thereby preventing the flower cluster from getting stuck in the cavity during separation, making it difficult to separate the two absorbing layers from each other.

[0024] 6. Attaching a pet-ito metamaterial film to the cloth strip can improve the wave absorption performance of the flower cluster.

[0025] 7. When separators are installed on both the first absorbing layer and the second absorbing layer, the separators are located between the first absorbing layer and the second absorbing layer. On the one hand, the deformation of the absorbing layer fabric caused by installing too many separators on a single absorbing layer can be reduced. On the other hand, the separators are hidden between the first absorbing layer and the second absorbing layer, which can effectively prevent the separators from affecting the appearance of the special-shaped camouflage net.

[0026] 8. The free end of the cloth strip is set as an arc. The purpose of this setting is that when the free end of the flower cluster is inserted into the cavity on the first absorbing layer or the second absorbing layer, the arc-shaped end edge of the cloth strip is more easily separated from the edge of the cavity formed by the cut flowers under pulling, making it easier to unfold the special-shaped camouflage net again after it is stored.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] like Figure 1 As shown, a special-shaped camouflage net with optical radar infrared camouflage stealth function includes, from bottom to top, a bottom net 3, a first absorbing layer 1 and a second absorbing layer 2, wherein the first absorbing layer 1 and the second absorbing layer 2 are both made of high-strength polyester decorative cloth, the surfaces of the high-strength polyester decorative cloth are coated with three-color multi-spectrum camouflage stealth coatings and the surface is cut, and after the first absorbing layer 1 or the second absorbing layer 2 is stretched, the cut portion is bent to form a cavity that can absorb electromagnetic waves; the first absorbing layer 1 is connected to a bottom net 3 on the side away from the second absorbing layer 2, and the bottom net 3 plays the role of supporting the entire special-shaped camouflage net with optical radar infrared camouflage stealth function, which is composed of a whole high-strength polyester cloth coated with camouflage absorbing coating; the overall three-layer net is sewn together by an industrial quilting machine, and the edges are sealed by polyester cloth folding stitching.

[0043] like Figure 1 , Figure 4 , Fig.11As shown, a separator for separating the first absorbing layer 1 from the second absorbing layer 2 is provided between the first absorbing layer 1 and the second absorbing layer 2, and the separator includes a flower cluster 5, and the flower cluster 5 includes 12 cloth strips, which are divided into an inner and outer layer. The cloth strips of each layer are arranged in a circular array, and the two layers of cloth strips are combined to form a "bud"-shaped flower cluster 5. The cloth strip is 26 mm long and 10 mm wide. The cloth strip is made of the same material as the first absorbing layer 1 and the second absorbing layer 2 to avoid affecting the camouflage effect of the entire camouflage net due to excessive material differences, and the front and back sides of the cloth strip are also coated with camouflage absorbing paint. The cloth strip includes The free ends 52 and the fixed ends 51, and the fixed ends 51 of all the cloth strips are fixed together and fixed on the first absorbing layer 1, so that the free ends 52 of all the cloth strips are in the shape of a flower cluster 5 radiating around the fixed ends 51 as the center, and a number of cloth strips are stacked from the center to the surroundings, so that the flower cluster 5 as a whole forms a separation unit, which partially separates the first absorbing layer 1 from the second absorbing layer 2. On the one hand, the cavity shape on the first absorbing layer 1 and the second absorbing layer 2 is more stretched, and on the other hand, the spatial disorder between the first absorbing layer 1 and the second absorbing layer 2 is increased, thereby enhancing the absorbing performance of the overall special-shaped camouflage net.

[0044] The free end 52 of the cloth strip is set as an arc. The effect of this setting is that when the free end 52 of the flower cluster 5 is inserted into the cavity on the first absorbing layer 1 or the second absorbing layer 2, the arc-shaped end edge of the cloth strip is more easily separated from the edge of the cavity formed by the cut flowers under pulling, so that the special-shaped camouflage net is easier to unfold again after being stored.

[0045] like Figure 4 As shown, the number of flower clusters 5 arranged within an area of ​​1.44 m2 (1.2 m×1.2 m) on the first absorbing layer 1 is 9.

[0046] Embodiment 2:

[0047] Different from the first embodiment, the fixed end 51 of the cloth strip is fixed on the second absorbing layer 2 , and the free end 52 of the flower cluster 5 faces the first absorbing layer 1 .

[0048] Embodiment 3:

[0049] Different from the first embodiment, the first absorbing layer 1 and the second absorbing layer 2 are both fixedly connected to the fixed end 51 of the cloth strip, the free ends 52 of the flower clusters 5 on the two absorbing layers are in opposite directions and the flower clusters 5 are staggered.

[0050] In the present embodiment, the position setting of the flower cluster 5 can increase the degree of separation of the first absorbing layer 1 and the second absorbing layer 2 by the partition, and the flower cluster 5 is hidden between the first absorbing layer 1 and the second absorbing layer 2, which can effectively avoid the partition from affecting the appearance of the special-shaped camouflage net. Moreover, through research, when the number of flower clusters 5 is greater than 9, the improvement on the camouflage net's absorbing performance is not obvious, and the weight of the camouflage net is greatly increased. Therefore, when the first absorbing layer 1 and the second absorbing layer 2 are both installed with flower clusters 5, the number of single-layer flower clusters 5 is set to 4 or 5.

[0051] Embodiment 4:

[0052] What is different from Example 1 is that a flower cluster 5 is installed on the side of the first absorbing layer 1 facing the bottom net 3, and the arrangement of the flower cluster 5 is consistent with the layout of the flower cluster 5 in Example 1. The fixed end 51 of the cloth strip of the flower cluster 5 is fixedly connected to the side of the first absorbing layer 1 facing the bottom net 3.

[0053] In this embodiment, the separator can separate the bottom net 3 from the first absorbing layer 1, so that the space inside the special-shaped camouflage net is more complex and the absorbing performance is enhanced.

[0054] Embodiment 5:

[0055] like Figure 2 , Figure 3 As shown, different from Example 1, a mounting net 4 is installed on one side where the first absorbing layer 1 and / or the second absorbing layer 2 is combined with the flower cluster 5, the flower cluster 5 is fixed on the mounting net 4 in the arrangement manner of Example 1, and the fixed end 51 of the cloth strip is fixedly connected to the mounting net 4; the mounting net 4 includes a plurality of crisscrossing mesh strips, the material of the mesh strips is the same as that of the first absorbing layer 1 and the second absorbing layer 2, and the mesh strips are coated with absorbing material;

[0056] The installation net 4 is detachably connected to the first absorbing layer 1 and / or the second absorbing layer 2 fixed to the separator by Velcro.

[0057] In this solution, the mounting net 4 is combined with the first absorbing layer 1 and / or the second absorbing layer 2. On the one hand, it can ensure that the first absorbing layer 1 or the second absorbing layer 2 maintains the shape after stretching, and ensures that the cavity shape on the absorbing layer is fully expanded during use. On the other hand, when the absorbing layer is pulled, the mounting net 4 can enhance the tensile strength of the absorbing layer.

[0058] At the same time, the flower cluster 5 is fixed on the installation net 4, and the number of flower clusters 5 installed on the installation net 4 can be adjusted according to demand, and then the installation net 4 is installed on the absorbing layer without modifying the absorbing layer. The installation net 4 and the absorbing layer can be assembled according to the use requirements, which is convenient and quick;

[0059] When the number of flower clusters 5 needs to be changed, two or more installation nets 4 can be staggered and stacked on the same absorbing layer to increase the number of flower clusters 5 per unit area.

[0060] Embodiment 6:

[0061] Different from the fifth embodiment, the installation net 4 is sewn together with the first absorbing layer 1 and / or the second absorbing layer 2 fixed to the partition.

[0062] Embodiment 7:

[0063] like Fig.12 As shown, what is different from Example 1 is that, among the several cloth strips of the flower cluster 5, the free end 52 of the cloth strip close to the center of the flower cluster 5 is fixedly connected to the middle part of the cloth strip away from the center of the flower cluster 5 and arranged adjacently; the free end 52 of a layer of cloth strip below away from the center of the flower cluster 5 is fixed to the first camouflage layer, and the middle part of the cloth strip is arched to form an arch-shaped supporting space.

[0064] In this embodiment, the free end 52 of the cloth strip is fixed to the middle part of the adjacent outer cloth strip, so that an arch-shaped supporting space can be formed between the adjacent cloth strips. Without increasing the weight of the flower cluster 5, the separation effect of the flower cluster 5 is improved only by changing the shape of the cloth strip. At the same time, several cloth strips can be connected in this way to form a pagoda shape for the flower cluster 5 as a whole, which is not easy to get stuck in the gap formed after the flowers are cut in the absorbing layer, thereby preventing the flower cluster 5 from getting stuck in the cavity during separation, making it difficult to separate the two absorbing layers from each other.

[0065] Embodiment 8, 9:

[0066] Different from Example 1, the number of flower clusters 5 arranged within an area of ​​1.44 m2 (1.2 m*1.2 m) on the first absorbing layer 1 or the second absorbing layer 2 is as shown in the following table:

[0067] Table 1: Number of flower clusters arranged on 1.44 m2 (1.2 m x 1.2 m) on the first absorbing layer 1 in Examples 8 and 9

[0068] Example 8 Example 9 Number of flower clusters 4 5

[0069] The arrangement of the flower cluster 5 in Example 8 is as follows Figure 5 As shown, the arrangement of the flower clusters in Example 9 is as follows Figure 6 shown.

[0070] Embodiment 10-12:

[0071] Different from Example 1, the length of the cloth strip of the flower cluster 5 is specifically shown in Table 2 below:

[0072] Table 2: Length of fabric strips for cluster 5

[0073] Example 10 Embodiment 11 Example 12 Strip length (mm) 34 41 46

[0074] Embodiment 13:

[0075] The difference from Example 1 is that pet-ito metamaterial films are attached to both the front and back sides of the cloth strip.

[0076] Comparative Example 1:

[0077] Different from the first embodiment, no separator is provided between the first absorbing layer 1 and the second absorbing layer 2 .

[0078] According to the camouflage net structure of the above embodiment and comparative example, models are established respectively, and RCS simulation analysis is performed using CST simulation software. The analysis results are as follows: Figure 4-Figure 7 As shown in the RCS simulation analysis diagram, as shown in the RCS simulation analysis diagram.

[0079] (1) RCS simulation tests were performed on Comparative Example 1, Example 1, Example 8, and Example 9. The results are as follows Figure 7 As shown, compared with comparative example 1, after the flower clusters 5 are set in embodiments 1, 8, and 9, the radar scattering cross-section value is reduced, indicating that the wave absorbing performance is improved; and through the comparison of embodiments 1, 8, and 9, it can be seen that the increase in the number of flower clusters 5 per unit area is positively correlated with the improvement of the wave absorbing performance of the special-shaped camouflage net, but increasing the density of the flower clusters 5 will also increase the weight and production cost of the camouflage net. After testing, based on the use weight, production cost and use effect, it is more appropriate to control the number of flower clusters 5 per unit area to 9.

[0080] (2) RCS simulation tests were performed on Example 1, Example 10, Example 11, and Example 12. The results are as follows: Figure 8 As shown, the length of the flower cluster 5 strips is positively correlated with the absorption performance of the special-shaped camouflage net.

[0081] (3) Example 1 and Example 13 were subjected to RCS simulation test, and the results were as follows Fig. 9 As shown, the PET-ITO metamaterial film composited on the cloth strips can significantly enhance the wave-absorbing performance of the camouflage net.

[0082] (4) RCS simulation test was performed on Example 1 (flower cluster 5 cloth strips are normal) and Example 7 (flower cluster 5 cloth strips are upright). The results are as follows: Fig.10 As shown, by changing the structure of the flower cluster 5 so that a supporting space is formed in the middle of the flower cluster 5, the wave absorbing performance of the camouflage net can be greatly improved.

[0083] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
