Description

Technical Field

[0001] This invention pertains to radar stealth devices and the field of container cabins. It relates to a radar stealth corner piece for container cabins, which can improve the attenuation performance of container cabins. Background Technology

[0002] The rapid development of detection technology and precision-strike weapons has made "detect and destroy" the norm on the battlefield. Equipment lacking stealth and protection capabilities will be in a dangerous situation of "nowhere to hide" and "no way to avoid." As a crucial piece of national defense equipment, the modular shelter will also face the fate of "detect and destroy" if its protective capabilities are not innovated and upgraded. Therefore, stealth design for modular shelters is urgently needed. Corner fittings, an important component of the modular shelter, suffer from the following drawbacks under radar detection due to their traditional metal casting methods:

[0003] 1. Large pieces of metal will be strongly exposed to radar detection;

[0004] 2. The surface is coated with a layer of material, which is susceptible to peeling due to environmental conditions or lifting operations, resulting in poor stealth performance.

[0005] 3. The radar stealth frequency band of the coating is limited, and it cannot achieve full-band radar stealth;

[0006] 4. The lifting holes of the corner fittings can create harmful cavity scattering sources. Summary of the Invention

[0007] Technical problems to be solved

[0008] To overcome the shortcomings of existing technologies, this invention proposes a container corner fitting with radar stealth capabilities.

[0009] Technical solution

[0010] A radar-stealth corner fitting for a container includes a corner fitting body 2; characterized in that it also includes a sealing plate 1; the sealing plate 1 is made of non-metallic elastic material and is embedded in the annular groove of the lifting hole on the corner fitting body 2, the size of which matches the annular groove of the lifting hole; the center of the sealing plate 1 has multiple cutting lines radiating outward from the center as the origin, forming a star-shaped outline. When the lifting is completed, the star-shaped outline closes, blocking the leakage of scattering sources in the container cavity and improving the container's attenuation performance.

[0011] The corner fitting body 2 is made of resin material to improve the attenuation performance of the container.

[0012] The corner piece body 2 is manufactured using 3D resin printing technology.

[0013] The edge of the sealing plate 1 and the edge of the lifting hole adopt multiple matching groove structures to form an interlocking structure.

[0014] The thickness of the sealing plate 1 is 3-10 mm.

[0015] The non-metallic elastic material of the sealing plate 1 is rubber.

[0016] The star-shaped outline structure of the sealing plate 1 is as follows: there are two parallel lines at the center, the middle break of the parallel lines is an arc, and the middle break is a series of outward radiating lines centered on the break.

[0017] The corner fitting body 2 includes right-angle, single-bevel, double-bevel, or multi-bevel cabin corner fittings.

[0018] Beneficial effects

[0019] This invention proposes a radar-stealth corner fitting for a container, comprising a corner fitting body; characterized in that it also includes a sealing plate; the sealing plate is made of non-metallic elastic material and is embedded in the annular groove of the hoisting hole on the corner fitting body, the size of which matches the annular groove of the hoisting hole; the center of the sealing plate has multiple cutting lines radiating outward from the center as the origin, forming a star-shaped outline; when hoisting is completed, the star-shaped outline closes, blocking the leakage of scattering sources in the container cavity and improving the container's attenuation performance.

[0020] This invention replaces the highly exposed metallic materials used by radar with resin materials, effectively reducing the probability of detection.

[0021] This invention eliminates radar cavity scattering sources by installing elastic non-metallic sealing plates at the lifting holes, further improving radar stealth from an aesthetic perspective.

[0022] By employing the two aforementioned technical means, this invention improves the RCS attenuation performance of the shelter by 60%. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the embodiments and accompanying drawings:

[0026] The radar stealth cabin corner piece in this embodiment is a right-angled cabin corner piece, and the three sides of the corner piece body 2 are designed with annular grooves for hoisting holes; it is made of resin material and manufactured using 3D resin printing technology.

[0027] The three sealing plates 1 are made of rubber and are 5mm thick. They are embedded in the annular grooves of the lifting holes on the corner fitting body 2, and their dimensions match the annular grooves of the lifting holes.

[0028] The edge of the sealing plate 1 and the edge of the hoisting hole adopt a structure of three mutually matching grooves to form an interlocking structure.

[0029] The sealing plate 1 has multiple cutting lines radiating outward from the center, forming a star-shaped outline. The star-shaped outline structure is as follows: there are two parallel lines at the center, the middle break of the parallel lines is an arc, and there are 7 radiating lines radiating outward from the middle break point, forming a star-shaped outline.

[0030] When hoisting is required, the star-shaped outline is opened by the hoisting structure to complete the hoisting task. After the hoisting task is completed, the star-shaped outline automatically closes due to the elasticity of the rubber material, preventing leakage of scattering sources from the internal cavity of the shelter and improving the attenuation performance of the shelter.
