Description

Technical Field

[0001] This utility model relates to the field of prefabricated cabin technology, and specifically discloses a protective structure for prefabricated cabins. Background Technology

[0002] Prefabricated modular smart substations, as a new model in substation construction, represent a significant application of new technologies, materials, and equipment in smart grid construction. They typically involve the fabrication, assembly, wiring, and commissioning of the substation structure, secondary equipment cabinets (or racks), and auxiliary facilities in a factory, followed by transportation as a complete unit to the construction site for installation. This construction model offers significant advantages such as short construction cycles, standardized quality, small footprint, and low environmental impact, leading to its increasingly widespread application in the power industry.

[0003] However, as a type of power facility that is installed outdoors for a long time or even permanently, the prefabricated cabin needs to withstand the severe tests of various complex natural environments and special operating environments, such as wind, sun, rain, snow disasters, temperature changes, salt spray and even industrial chemical gases, all year round.

[0004] Currently, the mainstream outdoor prefabricated cabins on the market generally adopt an integral welded structure for their outer wall protection, and use a heavy-duty anti-corrosion coating (such as spraying anti-corrosion paint or using a galvanized layer) on the outer surface. However, a single coating protection system has physical limits in terms of weather resistance, UV resistance, and mechanical strength. Under long-term harsh environments, the cabin surface, especially vulnerable areas such as corners, welds, and the bottom, will inevitably experience paint powdering, peeling, and even substrate corrosion. Once localized damage occurs, maintenance is extremely difficult: on-site repairs suffer from incomplete grinding and rust removal, poor coating adhesion, and unsatisfactory appearance; while refurbishing at the factory is costly and can lead to prolonged shutdown of some substation functions, seriously affecting power grid reliability. Therefore, improvements are needed. Utility Model Content

[0005] This utility model proposes a prefabricated cabin protective structure, which uses multiple modular protective panels to be quickly installed in the frame through a snap-fit ​​connection mechanism. The detachable anti-collision kick plate at the bottom allows any side wall protective panel or anti-collision kick plate to be quickly and independently disassembled and replaced if damaged, without damaging the surrounding structure or affecting the normal operation of the prefabricated cabin, thus achieving the effect of partial disassembly, repair and replacement.

[0006] This utility model is implemented as follows: a prefabricated cabin protective structure includes a prefabricated cabin body, with a U-shaped frame fixedly installed on each of the four side walls of the prefabricated cabin body. Two adjacent U-shaped frames are fixedly connected. Multiple modular protective panels are installed inside the U-shaped frames through a snap-fit ​​connection mechanism to form a protective layer covering the outer wall of the prefabricated cabin body.

[0007] The protective panel includes a first outer protective panel, a plurality of second outer protective panels, and a third outer protective panel disposed inside the loop frame. The plurality of second outer protective panels are located between the first outer protective panel and the third outer protective panel. The opposite sides of the first outer protective panel and the third outer protective panel are tightly fitted and connected to the inner wall of the loop frame.

[0008] The top of the prefabricated cabin is provided with a top protective cover, the top center of which is higher than the surrounding edges to form a drainage slope;

[0009] A waterproof platform is provided below the prefabricated cabin, and an anti-collision kick plate is fixedly installed on the top of the waterproof platform. The top of the anti-collision kick plate is detachably connected to the bottom of the prefabricated cabin by bolts.

[0010] As a preferred embodiment of the prefabricated cabin protective structure of this utility model, the buckle connection mechanism includes a buckle plate fixedly installed on the side of the first outer protective plate away from the inner wall of the U-shaped frame and the side of the second outer protective plate. The third outer protective plate on the side away from the inner wall of the U-shaped frame and the other side of the second outer protective plate are both provided with buckle grooves that are adapted to the buckle plate.

[0011] As a preferred embodiment of the prefabricated cabin protection structure of this utility model, sealing strips are fixedly installed on both sides of the card plate.

[0012] As a preferred embodiment of the prefabricated cabin protection structure of this utility model, the top and bottom of the inner side of the U-shaped frame are provided with mounting grooves, and the top and bottom of the first outer protective plate, the multiple second outer protective plates and the third outer protective plate are all fixedly installed with connecting plates that are compatible with the mounting grooves.

[0013] As a preferred embodiment of the prefabricated cabin protective structure of this utility model, the protective panel is a composite sandwich panel, with an outer layer of weather-resistant metal plate and an inner layer of thermal insulation material, and the outer surface of the protective panel is coated with a photocatalytic coating.

[0014] As a preferred embodiment of the prefabricated cabin protective structure of this utility model, the anti-collision kick plate is made of stainless steel.

[0015] As a preferred embodiment of the prefabricated cabin protective structure of this utility model, a door panel is provided between the front end face of the prefabricated cabin and the U-shaped frame located in front.

[0016] The beneficial effects of this utility model are:

[0017] Multiple modular protective panels are quickly installed within the frame via a snap-fit ​​connection mechanism, allowing any sidewall protective panel to be independently and quickly disassembled and replaced after damage, without damaging the surrounding structure or affecting the normal operation of the prefabricated cabin. This achieves the effect of partial disassembly, repair, and replacement. Furthermore, the detachable bottom anti-collision kick plate provides high-strength, corrosion-resistant dedicated protection for the most vulnerable bottom area. When the bottom anti-collision kick plate is damaged due to impact, corrosion, or accident, there is no need to cut, weld, or repair the main structure of the prefabricated cabin. It can be quickly replaced, thereby greatly reducing the maintenance cost and time cost throughout the entire life cycle. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-6 A prefabricated cabin protective structure includes a prefabricated cabin body 1. Each of the four side walls of the prefabricated cabin body 1 is fixedly installed with a U-shaped frame 3. Two adjacent U-shaped frames 3 are fixedly connected. Multiple modular protective panels 302 are installed inside the U-shaped frames 3 through a snap-fit ​​connection mechanism to form a protective layer covering the outer wall of the prefabricated cabin body 1.

[0028] The protective plate 302 includes a first outer protective plate 4, a plurality of second outer protective plates 5 and a third outer protective plate 6 disposed inside the loop frame 3. The plurality of second outer protective plates 5 are located between the first outer protective plate 4 and the third outer protective plate 6. The opposite sides of the first outer protective plate 4 and the third outer protective plate 6 are tightly fitted and connected to the inner wall of the loop frame 3.

[0029] The top of the prefabricated cabin 1 is provided with a top protective cover 2, and the top center of the top protective cover 2 is higher than the surrounding edges to form a drainage slope;

[0030] A waterproof platform 7 is installed below the prefabricated cabin 1, and an anti-collision kick plate 8 is fixedly installed on the top of the waterproof platform 7. The top of the anti-collision kick plate 8 is detachably connected to the bottom of the prefabricated cabin 1 by bolts.

[0031] In this embodiment, the U-shaped frame 3 serves as the main load-bearing structure, fixed to the outer wall of the prefabricated cabin 1, providing a stable installation foundation for the entire protection system. Subsequently, multiple modular protective panels 302 are quickly installed inside the frame via a snap-fit ​​connection mechanism. During the insertion of the card plate 502 into the slot 501, the sealing strips 503 on both sides are compressed, forming a continuous elastic sealing band between the plates, effectively preventing the lateral intrusion of rainwater and moisture. Simultaneously, all protective plates 302 are inserted into the mounting slots 301 of the frame via the top and bottom connecting plates 401, achieving precise vertical positioning and support, preventing the plates from falling out. This allows any sidewall protective plate to be quickly and independently disassembled and replaced after damage, without damaging the surrounding structure or affecting the normal operation of the prefabricated cabin, achieving the effect of partial disassembly, repair, and replacement. The top protective cover 2, with its high central and low perimeter drainage slope design, actively guides rainwater and snowmelt to the edges and drains them away, fundamentally avoiding the risk of water leakage from the top. The anti-collision kick plate 8 is detachably installed on the waterproof platform 7 with bolts, forming a dedicated protective band at the bottom of the cabin. When the anti-collision kick plate 8 is damaged due to long-term use, it can be replaced simply by removing the bolts, thus solving the problem of difficult repair of traditional structures.

[0032] As a technical optimization of this utility model, the buckle connection mechanism includes a buckle plate 502 fixedly installed on the side of the first outer protective plate 4 away from the inner wall of the U-shaped frame 3 and the side of the second outer protective plate 5. The third outer protective plate 6 on the side away from the inner wall of the U-shaped frame 3 and the other side of the second outer protective plate 5 are both provided with buckle grooves 501 that are adapted to the buckle plate 502.

[0033] In this embodiment: the first outer protective plate 4 serves as the starting plate, with a locking plate 502 on one side, which can only engage with the locking slot 501 of the adjacent second outer protective plate 5. The middle second outer protective plate 5 has a locking plate 502 on one side and a locking slot 501 on the other side, allowing it to function as both a "male" connector to connect to the downstream plate and a "female" connector to connect to the upstream plate, thus achieving bidirectional connection in the sequence. The third outer protective plate 6 serves as the ending plate, with a locking slot 501 on one side for engaging with the locking plate 502 of the last second outer protective plate 5, and the other side is finally positioned by fitting against the inner wall of the U-shaped frame 3.

[0034] As a technical optimization of this utility model, sealing strips 503 are fixedly installed on both sides of the card plate 502.

[0035] In this embodiment, the sealing strip 503 is made of ethylene propylene diene monomer (EPDM) rubber and is fixed to both sides of the card plate 502 with adhesive. Its compression rate is 20%-30% to ensure that it maintains its sealing performance under temperature changes. When the card plate 502 is inserted into the card slot 501, the sealing strip 503 fixed to both sides of the card plate 502 will undergo elastic deformation due to the compression of the side wall of the card slot 501. This elastic deformation fills the physical gap between the card plate 502 and the card slot 501, preventing capillary penetration of liquid water. The continuous elasticity ensures that the sealing interface can still maintain tight contact under thermal expansion and contraction or slight vibration, preventing seal failure.

[0036] As a technical optimization of this utility model, the top and bottom of the inside of the spiral frame 3 are provided with mounting grooves 301, and the top and bottom of the first outer protective plate 4, multiple second outer protective plates 5 and the third outer protective plate 6 are fixedly installed with connecting plates 401 that are compatible with the mounting grooves 301.

[0037] In this embodiment: the connecting plate 401 at the top of the protective plate 302 is inserted into the mounting groove 301 at the top of the U-shaped frame 3, mainly bearing the weight of the plate itself and transferring it to the U-shaped frame 3. The cooperation between the connecting plate 401 at the bottom and the mounting groove 301 is mainly used for precise positioning to prevent the plate from swaying back and forth. The mounting groove 301 forms a track, constraining the connecting plate 401 within it. This ensures that the plate will not be pulled up when subjected to negative wind pressure or other upward external forces, guaranteeing the reliability of the connection.

[0038] As a technical optimization of this utility model, the protective plate 302 is a composite sandwich panel, with an outer layer of weather-resistant metal plate and an inner layer of thermal insulation material 402. The outer surface of the protective plate 302 is coated with a photocatalytic coating.

[0039] In this embodiment: the weathering metal outer layer is an aluminized zinc-coated steel sheet, which has superior corrosion resistance (up to 2-6 times that of ordinary galvanized sheets) and heat resistance compared to traditional galvanized sheets. The cut edges have a "self-healing" property, which can effectively prevent the spread of rust on the cut edges. The insulation material 402 is a rigid polyurethane foam with a high closed-cell structure and strong hydrophobicity, which can effectively block water vapor. It has high bonding strength with the metal panel and can form a strong composite board, which greatly reduces the heat conduction rate. This provides excellent thermal insulation performance for the prefabricated cabin, reduces energy consumption for internal environmental control, and prevents condensation on the cabin walls.

[0040] The photocatalytic coating is a titanium dioxide (TiO2) coating with a thickness of 5-10 μm. Under sunlight (especially ultraviolet light), the coating produces a strong oxidizing substance that can decompose oil, organic matter, microorganisms, etc., adhering to the surface into harmless water and carbon dioxide. This photocatalytic process usually results in water forming a film on the surface rather than water droplets, thus allowing rainwater to carry away surface dust and decomposition products.

[0041] As a technical optimization of this utility model, the anti-collision kick plate 8 is made of stainless steel.

[0042] In this embodiment: Stainless steel material has high yield strength and hardness. When it is hit by ground gravel or tools, it can effectively resist plastic deformation and surface damage, that is, "impact resistance". It is specifically designed to deal with the harsh environment at the bottom of the prefabricated cabin 1 and solves the problem of easy corrosion and damage at the bottom of the prefabricated cabin.

[0043] As a technical optimization of this utility model, a door panel 101 is provided between the front end face of the prefabricated cabin 1 and the U-shaped frame 3 located in front.

[0044] In this embodiment, by installing door panel 101, the normal passage function of personnel and equipment is ensured after the modular protective layer is installed.

[0045] The working principle and usage process of this utility model are as follows: First, the U-shaped frame 3 is fixed to the outer wall of the prefabricated cabin 1 as the main load-bearing structure, providing a stable installation foundation for the entire protection system. Subsequently, multiple modular protective panels 302 are quickly installed in the frame through a snap-fit ​​connection mechanism (the cooperation between the snap plate 502 and the snap slot 501). By aligning the card plate 502 with the card slot 501 and gently pushing it until the card plate 502 is fully embedded in the card slot 501, the sealing strip 503 is sealed under pressure, forming a continuous elastic sealing band between the panels, effectively preventing the lateral intrusion of rainwater and moisture. At the same time, all protective panels 302 are inserted into the mounting slots 301 of the frame through the connecting plates 401 at the top and bottom, achieving precise vertical positioning and support, preventing the panels from falling out. This allows any side wall protective panel to be released by prying the edge of the card plate 502 when it is damaged, so that any side wall protective panel can be quickly and independently disassembled and replaced without damaging the surrounding structure or affecting the normal operation of the prefabricated cabin. This achieves the effect of partial disassembly, repair and replacement. Moreover, the protective panels 302 all adopt a composite sandwich panel structure. Its weather-resistant metal outer layer provides basic protection, while the thermal insulation material 402 significantly improves the heat insulation performance of the cabin, reduces energy consumption and prevents condensation. Its outer surface photocatalytic coating gives the entire protective layer a "self-cleaning" ability, using natural rainwater to keep the appearance clean and reduce the frequency of maintenance.

[0046] The top protective cover 2, with its high central section and low perimeter slope, actively guides rainwater and snowmelt to the edges for drainage, fundamentally preventing the risk of water leakage from the top. The anti-collision kick plate 8 is detachably bolted to the waterproof platform 7, forming a dedicated protective strip at the bottom of the cabin. Made of stainless steel, it possesses extremely high strength and corrosion resistance, specifically designed to withstand impacts from ground debris, mud and water erosion, and chemical corrosion, protecting the most vulnerable foundation parts of the cabin. When the anti-collision kick plate 8 is damaged due to long-term use, it can be replaced simply by removing the bolts, thus solving the problem of difficult repairs associated with traditional structures.
