Description

Technical Field

[0001] The utility model belongs to the technical field of communication shelters, and in particular relates to a high-performance electromagnetic shielding aluminum honeycomb shelter. Background Art

[0002] Electromagnetic shielding shelters are commonly used in the military, aerospace, and scientific research sectors to protect critical equipment from electromagnetic interference. Currently, domestic shelters are categorized by structure into three types: skeleton-type shelters, large-panel shelters, and carbon fiber / aramid fiber shelters. Specifically, skeleton-type shelters use a steel or aluminum alloy frame, with skin panels attached and then sprayed with polyurethane foam. These shelters are heavy, have a low load-to-weight ratio, and exhibit poor shielding performance, making them largely obsolete. Large-panel shelters utilize a full-width outer and inner skin, initially fabricated as a single composite panel. Six panels are then joined together, along with the inner and outer edges, by gluing or riveting. Due to the high foaming requirements, this structure often experiences bulging, secondary foaming, adhesive aging, rivet loss, and skin delamination. These issues also lead to leaks, reduced load-bearing strength, and the inability to recycle them after they are scrapped. Carbon fiber and aramid fiber shelters are difficult to promote due to their high material costs, complex and difficult production processes, and poor versatility. The high disposal costs associated with scrapped shelters make them difficult to commercialize. With the emergence of microwave weapons and the improvement of electromagnetic interference technology, there are more and more command and control units in the square cabins, and the carrying requirements of the square cabins are getting higher and higher. Traditional square cabins can no longer meet the requirements of modern development. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following is a clear and complete description of the technical solution of the present invention in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0028] According to the embodiment of the present invention, a high performance electromagnetic shielding aluminum honeycomb cabin is provided. Figure 1 and Figure 9 , including a cabin body, which includes a profile frame 100 and a bulkhead 200 connected by welding. The profile frame 100 is configured as a frame structure welded together by side beams and corner pieces 300. The bulkhead 200 is an aluminum honeycomb panel. The inner wall of the bottom bulkhead 201 is provided with a PET insulation layer 130, and the inner walls of the side bulkhead 202 and the top bulkhead are provided with a glass wool insulation layer 150.

[0029] It should be noted that the aluminum honeycomb panels are the primary material, with auxiliary profile skeletons 100 welded together to form an integrated, pure metal cabin. This reduces weight and reduces costs, meeting cabin load-to-weight ratio, lifting and transportation strength, sound insulation and noise reduction, and electromagnetic shielding requirements, without aging or degradation. The aluminum honeycomb panels ensure the cabin's overall sealing, while the PET insulation layer 130 and the glass wool insulation layer 150 serve as the cabin's internal insulation structure. The cabin's sealing and internal insulation are designed and constructed separately to ensure effective insulation. Furthermore, the cabin's interior utilizes an independent insulation design, facilitating cabin and wiring maintenance and preventing issues such as uneven surfaces, secondary foaming, bulging, and delamination of the sprayed polyurethane insulation.

[0030] Specifically, aluminum honeycomb panels, as the primary material for the cabin, not only enhance overall strength to meet load-bearing and lifting requirements, but also improve thermal insulation and impact resistance. For example, a 30mm thick welded aluminum honeycomb panel can withstand a 1kg aluminum bullet at a vertical impact load of 340km / h. The thermal conductivity of aluminum honeycomb panels is only 0.7-1.0W / mK, less than 1% of that of aluminum sheet. Combined with the cabin's internal insulation structure, this material improves the cabin's overall thermal insulation performance. The top bulkhead utilizes glass wool as an insulation layer, coated with aluminum foil, which provides both protection and electromagnetic shielding. Shielding sheaths and shielding magnetic rings are used at cable connection points. Waveguide windows and stainless steel mesh are added to openings such as air conditioning and fan ports to provide electromagnetic shielding.

[0031] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figures 1 to 2 The side beam at the junction of the bottom bulkhead 201 and the side bulkhead 202 is set as a right-angle side beam 101, and a first connecting edge 1011 and a second connecting edge 1012 extend from the right-angle side beam 101. The first connecting edge 1011 and the second connecting edge 1012 form a right angle. A first groove is opened on the right-angle side beam 101, and the inner wall and outer wall of the side bulkhead 202 are respectively connected to the first connecting edge 1011 and the first groove, and the outer wall of the bottom bulkhead 201 is connected to the second connecting edge 1012.

[0032] Specifically, the bottom bulkhead 201 is made of a 40 mm thick welded aluminum honeycomb panel and a profile frame 100 which are integrally welded together. At the same time, the bottom bulkhead 201 is provided with drainage holes.

[0033] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 and Figure 3The profile frame located at the junction of the top bulkhead 203 and the side bulkhead 202 is set as a rounded edge beam 102, and a third connecting edge 1021 and a fourth connecting edge 1022 are extended from the rounded edge beam 102. A rounded corner is formed between the third connecting edge 1021 and the fourth connecting edge 1022. A third groove and a fourth groove are opened on the rounded edge beam 102. The inner wall and outer wall of the top bulkhead 203 are connected to the third connecting edge 1021 and the third groove respectively, and the inner wall and outer wall of the side bulkhead 202 are connected to the fourth connecting edge 1022 and the fourth groove.

[0034] It should be noted that the top bulkhead 203 is designed with chamfered corners and rounded transitions to meet railway transportation requirements. The outer wall of the top bulkhead 203 is designed with safety buckles and handrails for personnel to protect themselves when climbing to the top.

[0035] Specifically, the top bulkhead 203 utilizes 30mm thick aluminum honeycomb panels, with rounded corners directly die-casted to reduce welds and improve overall load-bearing capacity. An aluminum alloy suspension structure is welded to the inner wall of the top bulkhead 203, accommodating the installation of internal piping and air conditioning ducts. The side bulkheads 202 utilize 30mm thick aluminum honeycomb panels, welded to the bottom bulkhead 201 and top bulkhead 203. Rounded edge beams 102 transition between the corners of the side bulkheads 202 and top bulkhead 203, forming an internal and external welded structure. The outer welds are polished smooth, while the inner surface is fillet welded.

[0036] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 and Figure 4 A flat-angled side beam 103 is arranged between adjacent aluminum honeycomb panels 204, a fifth connecting edge 1031 extends from the flat-angled side beam 103, and a fifth groove is opened on the flat-angled side beam 103. The fifth connecting edge 1031 and the fifth groove are symmetrically arranged around the flat-angled side beam 103, and the inner wall and outer wall of the aluminum honeycomb panel 204 are connected to the fifth connecting edge and the fifth groove respectively.

[0037] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 and Figure 5 A slide connector 500 is provided on the inner wall of the cabin, a first side of the slide connector 500 is welded to the inner wall of the cabin, and the other side of the slide connector 500 is recessed to form a slide 501.

[0038] It should be noted that the slide connector 500 is welded to the inner wall of the cabin, which reduces the number of side beams and makes construction more convenient.

[0039] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 、 Figure 6as well as Figure 7 An aluminum-clad iron composite component 600 and / or an embedded iron component 800 is provided on the inner wall of the cabin.

[0040] It should be noted that the aluminum-clad iron composite assembly 600 has an outer layer of aluminum alloy profiles and an inner core of galvanized steel sheets, combining the dual properties of aluminum and iron. Furthermore, the aluminum alloy profiles and galvanized steel sheets are tightly bonded, leaving no gaps between them, preventing rust and separation. The aluminum-clad iron composite assembly 600 can be connected with connecting bolts 700 for easy assembly. The buried iron assembly 800 has an outer layer of aluminum alloy profiles with an inner cavity in which the galvanized steel sheets are fixed. This configuration effectively improves overall rigidity and is suitable for punching and securing light-load equipment.

[0041] Specifically, the control console can fix the buried iron component 800, and the buried iron component 800 is welded to the inner wall of the cabin. At the same time, a foam board is set around the buried iron component 800.

[0042] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 and Figure 9 The inner wall of the side bulkhead 202 is also provided with an interior panel 160, and the glass wool insulation layer 150 is in contact with the outer surface of the interior panel 160. The inner wall of the bottom bulkhead 201 is also provided with a floor 140, and the PET insulation layer 130 is in contact with the outer surface of the floor 140. A curved skirting board 170 is provided at the junction of the interior panel 160 and the floor 140.

[0043] It should be noted that the interior panels 160 provide a comfortable working environment and should be made of environmentally friendly materials. Specifically, the panels are 10mm thick aluminum honeycomb panels, painted with H06-1012H epoxy primer and topcoated with ice-gray fluorocarbon paint. The floor 140 is a 1.5mm thick aluminum sheet. The PET insulation layer 130 is bonded to the floor 140 to form a sandwich structure. A 3mm thick floor cloth is applied over the floor 140, sealed around the perimeter with glue. The curved skirting board 170 is glued and riveted to the side bulkhead 202 and the floor 140 to achieve internal watertightness. The curved skirting board 170 is made of 1.5mm thick stainless steel sheet bent with a brushed finish.

[0044] In the high performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, please refer to Figure 1 and Figure 8 A hatch 400 is provided on the cabin body, and a sealing strip 110 and an electromagnetic shielding strip 120 are provided between the hatch 400 and the door frame profile 900.

[0045] It should be noted that the hatch 400 is composed of 30mm honeycomb panel + 20mm PET foam panel, which has high strength and light weight. A sealing strip 110 is provided for sealing, and has good thermal insulation and sealing properties. An electromagnetic shielding strip 120 is also provided between the hatch 400 and the door frame profile 900, which has a good electromagnetic shielding effect.

[0046] Specifically, the sealing strip 110 fills the gap between the cabin door 400 and the door frame profile 900. At the same time, electromagnetic shielding strips 120 are provided on both sides of the gap, which can effectively prevent external electromagnetic interference signals and water vapor from entering the interior of the cabin through the gap.

[0047] In the high-performance electromagnetic shielding aluminum honeycomb cabin of this embodiment, the outer wall of the side bulkhead is provided with a hanging ring and a U-shaped fixing groove, the boarding ladder is connected to the hanging ring through a hook, and the ladder frame of the boarding ladder is embedded in the U-shaped fixing groove, and the side wall of the U-shaped fixing groove is provided with a fixing bolt threadedly connected thereto, and the end of the fixing bolt is against the ladder frame of the boarding ladder.

[0048] It should be noted that the boarding ladder consists of a ladder frame, non-slip pedals and hooks, and is made of aluminum alloy, which is lightweight; it is fixed to the outer wall of the cabin by hooks, hanging rings and U-shaped fixing grooves; when in use, screw the fixing bolts, lift it up, and the hook will be detached from the hanging ring and can be quickly taken out for use; when not in use, the hook is hung on the hanging ring, the ladder frame is embedded in the U-shaped fixing groove, and it can be quickly fixed by screwing the fixing bolts.

[0049] In summary, the high-performance electromagnetic shielding aluminum honeycomb cabin of this application has the following properties:

[0050] 1. High strength and lightweight: Compared with the traditional large-panel shelter, the overall weight is reduced by about 15-20%. The average surface density of the traditional large-panel shelter is about 35Kg / ㎡, while the average surface density of this application does not exceed 25Kg / ㎡. According to the load requirements, the corresponding strength of the aluminum honeycomb panel is selected to achieve full-load lifting.

[0051] The tensile strength of high-performance welded aluminum honeycomb panels can reach 6Mpa, and the tensile strength of polyurethane foam sandwich panels is about 0.4Mpa; the compressive strength of high-performance welded aluminum honeycomb panels can reach 4.5Mpa, and the compressive strength of polyurethane foam sandwich panels is about 0.8Mpa.

[0052] 2. Good sealing and shielding properties: Traditional large-plate square cabins generally adopt a bonding and riveting structure, and water leakage and seepage often occur during use. The joints on the outer surface of this application are all fully welded and subjected to penetrant testing. Relying on welding to ensure watertightness is also a common method for watertight requirements of rail vehicles; the six cabin surfaces of traditional large-plate square cabins are connected by rivets, and gaps are easily present between surfaces, resulting in poor electromagnetic shielding. This application uses welded aluminum honeycomb panels and aluminum profile frames to be welded into a whole, and there is no gap between surfaces. The cabin door adopts a structure that combines sealing strips and electromagnetic shielding strips. The air-conditioning vents are added with waveguide windows, and the cable wall connection positions use shielding sheaths and shielding magnetic rings, etc., so that it has good shielding properties. At a frequency of 950Hz, the shielding effectiveness can reach 100dB.

[0053] 3. Strong impact resistance: The interior of the welded aluminum honeycomb panel is a designable regular hexagonal column, and its sub-vacuum structure has the ability to disperse impact loads and absorb compression energy. According to test results, a 25mm thick aluminum honeycomb panel sample can withstand a 1kg aluminum bullet at a vertical speed of 340km / h, and the aluminum bullet cannot penetrate the test sample.

[0054] 4. Good stability and not easy to age: The polyurethane foam of traditional large-plate shelters inevitably has the problem of polymer material aging, which causes the mechanical properties to decline after aging. This application is made of welded aluminum alloy, which has no aging and degradation problems.

[0055] 5. Good thermal insulation: Traditional large-plate square cabins rely on large polyurethane panels as thermal insulation materials, with internal embedded skeletons or iron blocks as load-bearing structures. During design, both load-bearing and thermal insulation must be considered, which brings great difficulty and uncontrollability to the design and construction work. Once the design is changed, the subsequent workload is very large. This application uses welded aluminum honeycomb panels as the main material, and uses full welding to connect them to ensure the overall sealing of the cabin. At the same time, the thermal conductivity of the welded aluminum honeycomb panels is 0.68W / mK. The cabin insulation and the cabin insulation are designed and constructed separately, which can better ensure the thermal insulation effect of the cabin. The construction process is more controllable, the insulation material selection is more extensive, the degree of modularization is higher, the maintainability and security are stronger, and the rework workload can be reduced when the design is changed.

[0056] 6. Environmentally friendly and recyclable: Traditional large-plate shelters use a lot of non-metallic materials, which will cause environmental problems from the manufacturing to the disposal process. This application is made of aluminum alloy, which is easy to recycle and reuse.

[0057] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
