[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0032] like Figures 1 to 7As shown, this application embodiment provides a box structure for a railway communication base station, including a frame and wall panels connected to the frame. The frame includes a bottom support frame 11, side wall frames, and a top wall frame. The wall panels include a bottom wall panel 12 fixed to the bottom support frame 11, side wall panels and door panels 3 fixed to the side wall frames, and a top wall panel 4 fixed to the top wall frame. The bottom wall panel 12 and the bottom support frame 11 together form the base 1 of the box structure. The structure of the wall panels includes an inner frame 121, an aluminum honeycomb structure 122 embedded in the inner frame 121, and a skin structure 123 covering the outer surface of the inner frame 121 and the aluminum honeycomb structure 122.

[0033] Specifically, the frame is rectangular in shape, with wall panels wrapped around the outside of the frame to create a closed installation space. The wall panels use an internal frame 121 with an embedded aluminum honeycomb structure 122, and then cover the outer surface with a skin structure 123. The entire box structure is modularly designed for easy transportation and assembly. The frame enhances the strength of the box structure. The wall panels use an internal frame 121 with an embedded aluminum honeycomb structure 122 and a skin structure 123 on the outer surface. This not only provides high structural strength, but the skin structure 123 also protects the internal frame, reduces the possibility of corrosion, and has good thermal insulation effect.

[0034] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the base frame 11 includes an outer frame 111 and an inner frame 112 connected between the inner walls of the outer frame 111. The bottom surface of the inner frame 112 is provided with a forklift plate 113, and an upwardly recessed forklift groove is formed on the forklift plate 113 to cooperate with the forklift fork.

[0035] Specifically, the base frame 11 is made of 304 stainless steel and assembled by welding. The outer frame 111 includes four main outer frame beams, which are connected end to end to form a rectangular frame. The inner frame 112 includes secondary inner frame beams, which are connected to the outer frame in both the transverse and longitudinal directions. The inner frame 112 serves to strengthen the structure within the outer frame 111. A 2mm thick stainless steel inner plate is laid on the base frame.

[0036] For example, in some embodiments of this application, the outer frame main beam is made of 304 stainless steel profiles with dimensions of 90mm×60mm×3mm (length) and 60mm×60mm×3mm (width), respectively, and the inner frame secondary beam is made of 304 stainless steel profiles with dimensions of 30mm×20mm×2.5mm. L-shaped connectors 124 are provided at the connection points of the inner frame secondary beam and the outer frame main beam at various locations. The inner frame secondary beam and the outer frame main beam are fixed together by welding or by screws at various locations to form a whole. The forklift plate 113 is arranged along the width direction of the inner frame 112, and two forklift plates 113 are arranged at intervals to cooperate with the forks on the forklift plate 113. The forklift plate 113 forms an upwardly recessed forklift groove. When the base support frame is lifted by a forklift, the forklift forks are inserted into the forklift groove, and the forks and forklift groove are tightly cooperated. On the one hand, the forks support the base support frame 11, and on the other hand, the forks also prevent the base support frame 11 from swaying left and right when it is lifted.

[0037] Combination Figure 2 As shown, in some embodiments of this application, the base frame 11 further includes a fixing post 13 and a protective plate 15. There are multiple fixing posts 13, which are distributed in a rectangular array on the base frame 11. The protective plate 15 is connected between two adjacent fixing posts 13, forming a rectangular installation space. The fixing posts 13 are provided with a first fixing hole for connecting the side wall frame to the fixing post 13. The protective plate 15 corresponding to the side wall plate 2 is provided with a second fixing hole for fixing the lower end of the side wall plate 2 to the protective plate 15.

[0038] Specifically, in some embodiments of this application, there are four fixing posts 13, which are correspondingly set at the four corners of the outer frame 111. The fixing posts 13 are set on the upper surface of the outer frame 111. There are four protective plates 15, which are respectively set between the four fixing posts 13, together forming a rectangular installation space. The protective plates 15 are used to provide installation support for the side wall panel 2.

[0039] In some embodiments of this application, a fixing member 14 is also provided on the outer side of the outer frame 111. The fixing member 14 is used to fix the bottom support frame 111. Specifically, there are four fixing members 14, which are respectively connected to the outer sides of the four corners of the outer frame 111. The fixing member 14 is L-shaped, with one side fitting against the outer surface of the outer frame 111 and the other side parallel to the lower surface of the outer frame 111. The fixing member 14 is provided with connecting holes for connecting the bottom support frame 11 to other structures to achieve the fixation of the box structure. The bottom surface of the fixing member 14 is set lower than the outer surface of the bottom support frame 11. In this way, the fixing member 14 can lift the bottom support frame 11, so that a certain gap is formed between the bottom support frame 11 and the fixing surface, which facilitates the installation of internal components and wiring of the box structure. At the same time, the bottom support frame 11 does not contact the fixing surface, which can also play a certain role in moisture prevention and corrosion prevention.

[0040] In some embodiments of this application, the fastener 14 and the fixing post 13 are an integral structure, and the two together form a corner piece, that is, connected to the corner of the outer frame 111. The fixing post protrudes from the upper surface of the outer frame 111, and the fastener 14 is fitted to the outer surface of the outer frame 111.

[0041] In some embodiments of this application, the side wall frame includes columns 6 and beams 62. There are two columns 6 arranged in parallel, and both ends of the beams 62 are connected to the upper ends of the two columns 6 respectively. The lower ends of the columns 6 are correspondingly connected to the fixed columns 13. There are two side wall frames arranged opposite each other. The door panel 3 is installed between the two columns 6 of a single side wall frame, and the side wall panel 2 is installed between the two side wall frames.

[0042] Specifically, the column 6 is made of three 50mm×50mm×3mm 304 stainless steel profiles welded together. After the mounting inserts that connect to the fixed column on the base frame are embedded inside, the ends are sealed with 5mm thick stainless steel plate 61. Finally, a 5mm thick skin mechanism is wrapped around the outside of the column to ensure its corrosion resistance. During installation, the column 6 is connected to the fixed column 13 with screws, and structural adhesive is applied to each mating surface for waterproof sealing.

[0043] The column, formed by three stainless steel profiles, has an L-shaped cross-section, with its lower end abutting against the upper surface of the outer frame. The stainless steel plate 61 is also L-shaped, with its lower end abutting against the upper end of the fixed column 13. The column 6 is located outside the stainless steel plate 61, and its lower side is bolted to the fixed column 13. The upper side of the column 6 is also bolted to the stainless steel plate 61. Structural adhesive is applied to all contact surfaces for waterproofing. The outer surface of the column is covered with a skin structure for corrosion protection.

[0044] like Figure 8 As shown, in some embodiments of this application, the skin structure includes a basalt composite layer and carbon fiber composite layers disposed on both sides of the basalt composite layer, forming a sandwich structure. Specifically, the basalt composite layer is made of basalt fiber with an epoxy phenolic resin system, and the carbon fiber composite layer is made of T300 carbon fiber fabric. Whether it is the bottom wall panel 12, the side wall panel 2, the door panel 3, or the top wall panel 4, all adopt an internal frame 121 embedded with an aluminum honeycomb structure 122, and are covered with a skin structure 123 on the outer surface. The skin structure 123 covers the inner and outer sides of the bottom wall panel 12, the door panel 3, the side wall panel 2, and the top wall panel 4.

[0045] like Figure 6 As shown, taking the bottom wall panel 12 as an example, the total thickness of the bottom wall panel 12 is 56mm, of which the inner and outer skin structures 123 are each 3mm thick, and the middle is filled with a 50mm thick aluminum honeycomb structure 122; the inner and outer skin structures are both made of a composite material of basalt fiber and T300 carbon fiber fabric in epoxy phenolic resin system, with a thickness of 3mm; the internal frame 121 is made of 50mm×40mm×3mm basalt fiber drawn square tubes riveted together with L-shaped connectors (basalt fiber), and the frame contains 304 stainless steel inserts for connecting the bottom support frame 11 and for equipment installation; the skin structure 123 is compositely made with the wall by riveting and structural adhesive bonding.

[0046] The side wall panel 2 is similar to the bottom wall panel 12 in terms of material selection, size, structure, and molding process. The left side wall panel 2 has a 20mm inner diameter PVC pipe installed inside for wiring of equipment and switches within the enclosure, and grounding terminal mounting holes are designed according to interface requirements. The right side wall panel has ventilation holes and air conditioning mounting holes for internal and external air circulation within the enclosure and for the installation of external air conditioning. The left and right side wall panels are assembled to the base frame 11 using screws and cylindrical pins. The side wall panels 2 are connected to the columns 6 using corner brackets and screws. The contact surfaces with each structure are sealed with structural adhesive.

[0047] The top wall panel 4 is composed of an internal frame 121, an outer skin, an inner skin, an aluminum honeycomb structure 122, side panels, sealing strips, PVC pipes, and frame inserts, with a thickness of 56mm. The internal frame 121 is made of 50mm×40mm×3mm basalt fiber drawn square tubes riveted together with L-shaped connectors. 304 stainless steel inserts are installed at the four corners of the internal frame 121, and the top wall panel 4 is connected to the column 6 with screws. The internal frame 121 is filled with aluminum honeycomb structure and PVC pipes and then combined with the inner skin. The materials, dimensions, and assembly methods are consistent with those of the side wall panel 2. The outer skin structure is designed with a 2° slope "A" shaped structure, with a fence around the perimeter. Drainage outlets are opened on both sides of the left end, which can be drained through external downpipes. The thickest part in the middle is 13mm, transitioning to both ends. The whole is made of composite material panels spliced ​​together.

[0048] After the internal frame 121, inner skin, aluminum honeycomb structure 122, and PVC conduit of the top wall panel 4 are assembled by riveting and gluing, the uninstalled top wall panel 4 is placed on top of the box structure, and the sealing strip is fixed to the internal frame 121 of the top wall panel 4 with structural adhesive. The outer skin of the top wall panel 4 is then placed on top, and the four corners of the top wall panel 4 are combined with the columns using screws. Finally, the outer skin is riveted to the internal frame 121 of the top wall panel 4 around its perimeter, and the sealing strip is tightened. Two downpipes are installed at the left end column to drain the water accumulated at the top. Finally, the protective plates at the front and rear ends of the top wall panel are installed and positioned by gluing. A 304 stainless steel lightning protection mesh 5 is installed around the internal frame of the top wall panel 4, with mounting bases installed every 300mm and riveted to the side of the top wall panel 4. A 5mm×40mm 304 stainless steel downleader is used to connect the left side to the bottom support frame 11.

[0049] The single-sided entrance door consists of two panels, left and right. The left panel is similar to the side wall panel, while the right panel is composed of an internal frame, inner and outer skins, an aluminum honeycomb structure, a door lock shaft, a door lock box, and L-shaped connectors, with a thickness of 56mm. The internal frame, inner and outer skins, etc., are made of the same material and structure as the left and right side panels. The door panel is installed on the column in the form of hinges, and the door panel is opened, closed, and sealed by rotating the door lock shaft.

[0050] In some embodiments of this application, in order to avoid direct contact between the equipment inside the box structure and the composite material of the bottom wall plate, an equipment mounting base composed of L-shaped profiles made of 45 steel with a thickness of 5mm is installed on the bottom wall plate and the metal base by means of screw connection.

[0051] Furthermore, electrical equipment is installed on the enclosure structure, requiring the embedding of conduits in the side wall panels 2 and top wall panels 4. Cameras and lighting fixtures are installed on the top wall panel 4 and / or side wall panels 2; wiring holes and equipment mounting holes are provided on the bottom wall panel 12. The wiring holes are used for external cables to pass through into the enclosure structure, and the equipment mounting holes are used to mate with the equipment mounting base inside the enclosure structure to fix the equipment mounting base.

[0052] The side wall panel 2 is also equipped with an air outlet 201 for air circulation inside and outside the box structure, which has achieved cooling of the inside of the box structure.

[0053] To prevent the lifting ropes from squeezing the wall panels during the hoisting of the box-type structure, eye bolts are designed and installed on the four sides of the top wall panel. During hoisting, the lifting ropes are connected to the shackles and fixed to the corner pieces of the base frame 11, passing through the eye bolts, and then hoisted using a special lifting tool. The special lifting tool is a bridge-type lifting tool, with two lifting points on each long side of the box-type structure. The width of the bridge-type lifting beam is slightly wider than the width of the box-type structure to ensure that the lifting ropes do not tighten around the columns during hoisting.

[0054] In some embodiments of this application, a thermal insulation layer is provided on the outer surface of the wall panel. The thermal insulation layer in this embodiment uses aerogel, specifically SiO2 aerogel paste, with a thickness of 2 mm and a thermal conductivity of 0.012 (W / m·℃), which is lower than that of conventional insulation materials. The aerogel is used for thermal insulation of the enclosure structure, and is sprayed onto the outer skin surface of the wall panel to achieve overall coverage of the enclosure structure, thereby improving its thermal insulation performance.

[0055] The enclosure structure adopts an assembled frame structure, and all structural joints are sealed with structural adhesive. The door panels are sealed using compression sealing strips, and sealing strips are designed between the top wall panels and the internal frame. During the installation of the top wall panels, the compression strips ensure a seal at the top. Therefore, the enclosure structure fully meets the sealing and waterproofing requirements throughout its lifespan; that is, the waterproofing level at the connection points of the equipment room should not be lower than Class II as specified in GB50345-2012.

[0056] The corrosion protection design of the box structure has been comprehensively designed from the perspective of the overall scheme design, including the selection of materials for the box structure.

[0057] First, all metal parts exposed in the enclosure structure are designed to be made of 304 stainless steel and have undergone surface passivation treatment, which can solve the corrosion problem throughout the entire life cycle of the enclosure structure.

[0058] Secondly, all non-metallic parts exposed outside the enclosure structure are designed to be made of materials such as basalt fiber or carbon fiber with a heat-resistant and flame-retardant resin system as the matrix and are surface-coated, which can also solve the corrosion problem throughout the entire life cycle of the computer room.

[0059] By relying on materials such as basalt fiber or carbon fiber with a heat-resistant and flame-retardant resin system as the matrix and the application of water-repellent thermal insulation aerogel plaster as the wall coating material, the moisture-proof performance of the box structure is guaranteed from the source.

[0060] The design of the enclosure structure has taken electromagnetic shielding into account, specifically by laying two layers of 0.2mm thick carbon fiber fabric in the skin structure of the wall panels and the forming of the columns. Tests have been conducted on specimens formed from carbon fiber fabric of a certain thickness, proving its electromagnetic shielding capability. Therefore, the overall electromagnetic shielding performance of the enclosure structure is adequately guaranteed by design.

[0061] The heat-resistant, fire-resistant, and UV-resistant design of the enclosure structure is primarily based on the selection of materials used in its design. The main materials comprising the enclosure structure include basalt fiber, carbon fiber, aerogel, 304 stainless steel, and a heat-resistant and fire-resistant resin matrix. This results in excellent heat resistance, fire resistance, and UV protection.

[0062] Because lightning protection strips are relatively lightweight but occupy a large space, they are mounted on the top wall panel using round steel, with flat steel used as the bottom lead. Grounding studs are designed at the four corners of the base frame for anti-static connection points. The foundation grounding of the enclosure structure can be effectively achieved through welding connections.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0064] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
