Description

Technical Field

[0001] This invention relates to a prefabricated power cabin, specifically a waterproof and heat-insulating prefabricated power cabin using vacuum insulation panels. Background Technology

[0002] Precast modules are increasingly being used in power systems. A typical precast module has a two-layer structure, consisting of an inner panel and an outer panel, with an insulation layer between them. This insulation layer uses rock wool or polyurethane to meet insulation performance requirements. The performance of the insulation material directly affects the overall insulation performance of the precast module, and even the normal operation of the equipment.

[0003] Currently, the insulation material in conventional prefabricated cabins is fixed by laying it flat and using flat iron. The main drawback is that due to structural reasons, insulation material cannot be properly laid in some sections of the steel structure, resulting in dead corners in the cabin wall where insulation is not possible. In other words, the insulation performance of prefabricated cabins in existing technologies cannot meet the technical requirements, and it can also lead to cold bridges inside the cabin, resulting in condensation and directly threatening the normal operation of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproof and heat-insulating prefabricated electrical cabin using vacuum insulation board material that can greatly improve the thermal insulation performance of the prefabricated cabin, thereby solving the problems of defects in the laying of the original insulation material and the condensation caused by cold bridges, and ensuring that the equipment can operate normally.

[0005] To achieve the above objectives, the technical solution of this invention is: a waterproof and heat-insulating prefabricated electric cabin using vacuum insulation material, comprising a cabin body and a cabin roof located on top of the cabin body, wherein the cabin body is provided with a cabin door, the innovation of which is:

[0006] The cabin includes a cabin frame, a first vacuum insulation panel, an aluminum-plastic composite panel, a cabin insulation layer, and an outer wall panel. The inner side of the cabin frame is provided with an aluminum-plastic composite panel, and the outer side of the cabin frame is provided with a first vacuum insulation panel for waterproofing and heat insulation. The outer wall panel is assembled and connected to the cabin frame, and the outer wall panel is located on the outer surface of the first vacuum insulation panel. The cabin insulation layer is filled between the outer wall panel and the first vacuum insulation panel.

[0007] The cabin roof includes a cabin roof frame, a top plate, a second vacuum insulation board, and a cabin roof insulation layer. The cabin roof frame is assembled and connected to the cabin body frame. The outer side of the cabin roof frame is provided with a top plate, and the inner side of the cabin roof frame is provided with a second vacuum insulation board for waterproofing and heat insulation. The cabin roof insulation layer is filled between the top plate and the second vacuum insulation board.

[0008] In the above technical solution, the outer wall panel is fixed to the cabin frame by an outer wall fixing plate.

[0009] In the above technical solution, both the first vacuum insulation board and the second vacuum insulation board are composed of a vacuum insulation board body and a foamed polyurethane covering the outer periphery of the vacuum insulation board body. The vacuum insulation board includes a core material and a metal aluminum foil that is vacuum-sealed and covered around the core material to prevent damage to the core material.

[0010] In the above technical solution, the aluminum-plastic composite panel is fixed to the inner side of the cabin frame by a flexible metal buckle, and the metal buckle itself also has reverse teeth that can reliably fix the aluminum-plastic composite panel.

[0011] In the above technical solution, the cabin frame includes multiple uprights arranged around the perimeter, as well as crossbeams and reinforcing beams. Multiple horizontally arranged crossbeams are provided between two adjacent uprights from top to bottom, and reinforcing beams are arranged at an angle to strengthen the connection between two adjacent uprights.

[0012] In the above technical solution, the exterior wall panel is fixed to the reinforcing beam by an exterior wall fixing plate, and the exterior wall panel is fixed to the exterior wall fixing plate by countersunk screws, and the exterior wall fixing plate is welded and fixed to the reinforcing beam.

[0013] In the above technical solution, the outermost surface of the cabin frame is provided with multiple spliced ​​outer wall panels, and adjacent outer wall panels are connected by H-shaped connectors.

[0014] In the above technical solution, the cabin frame is provided with multiple fixed guide rails, and the upper and lower ends of the first vacuum heat insulation plate are respectively slidably engaged with the corresponding fixed guide rails.

[0015] In the above technical solution, each crossbeam on the cabin frame is provided with a fixed guide rail at its top and bottom, and a first vacuum heat insulation plate is provided between adjacent crossbeams, with the upper and lower ends of the first vacuum heat insulation plate slidingly engaged with the corresponding fixed guide rail.

[0016] In the above technical solution, the second vacuum insulation plate is fixed to the inner side of the cabin top frame by sheet metal parts.

[0017] The positive effects of this invention are as follows: When using the waterproof and heat-insulating prefabricated electric cabin made of vacuum insulation material according to this invention, the cabin body includes a cabin frame, a first vacuum insulation panel, an aluminum-plastic composite panel, a cabin insulation layer, and an outer wall panel. The inner side of the cabin frame is provided with an aluminum-plastic composite panel, and the outer side of the cabin frame is provided with a first vacuum insulation panel for waterproofing and heat insulation. The outer wall panel is assembled and connected to the cabin frame, and the outer wall panel is located on the outer surface of the first vacuum insulation panel. The cabin insulation layer is filled between the outer wall panel and the first vacuum insulation panel.

The outer side of the roof frame is provided with the top plate, and the inner side of the roof frame is provided with the second vacuum insulation panel for waterproofing and heat insulation. The roof insulation layer is filled between the top plate and the second vacuum insulation panel.

[0019] The cabin and roof of this invention not only have an insulation layer, but also have vacuum insulation panels laid on the frame. The advantages of this design are: First, the insulation performance of the prefabricated cabin is formed by the combination of the insulation layer and the vacuum insulation panels, which greatly improves the insulation effect. Second, after laying the insulation layer and the vacuum insulation panels at the same time, the situation where insulation material cannot be properly laid on some steel sections due to structural reasons, as in the prior art, will not occur. This invention can ensure that the cabin and roof can be fully insulated, without any insulation dead corners, thus meeting the insulation requirements and better isolating external heat. Condensation will no longer occur inside the cabin due to cold bridges, ensuring the normal operation of the equipment. At the same time, the cooling energy generated by the industrial air conditioner can be stored inside the cabin, thereby reducing air conditioning energy consumption and extending the service life of the air conditioner.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but is not limited thereto.

[0028] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, a waterproof and heat-insulated prefabricated electric cabin using vacuum insulation panel material includes a cabin body and a cabin roof located on top of the cabin body. The cabin body is equipped with a cabin door.

[0029] The cabin includes a cabin frame 1, a first vacuum insulation panel 2, an aluminum-plastic composite panel 3, a cabin insulation layer 4, and an outer wall panel 5. The inner side of the cabin frame 1 is provided with the aluminum-plastic composite panel 3, and the outer side of the cabin frame 1 is provided with the first vacuum insulation panel 2 for waterproofing and heat insulation. The outer wall panel 5 is assembled and connected to the cabin frame 1, and the outer wall panel 5 is located on the outer surface of the first vacuum insulation panel 2. The cabin insulation layer 4 is filled between the outer wall panel 5 and the first vacuum insulation panel 2.

[0030] The cabin roof includes a cabin roof frame 6, a top plate 7, a second vacuum insulation board 8, and a cabin roof insulation layer 9. The cabin roof frame 6 is assembled and connected to the cabin body frame 1. The outer side of the cabin roof frame 6 is provided with the top plate 7, and the inner side of the cabin roof frame 6 is provided with the second vacuum insulation board 8 for waterproofing and heat insulation. The cabin roof insulation layer 9 is filled between the top plate 7 and the second vacuum insulation board 8.

[0031] like Figure 6 As shown, in order to facilitate the fixing of the outer wall panel to the cabin frame 1, the outer wall panel 5 is fixed to the cabin frame 1 by the outer wall fixing plate 10.

[0032] Furthermore, the thickness of the external wall fixing plate 10 is not less than 2mm, and the external wall plate 5 of each prefabricated cabin body is fixed at multiple points.

[0033] Furthermore, to ensure that the vacuum inside the vacuum insulation panel is not disrupted, both the first vacuum insulation panel 2 and the second vacuum insulation panel 8 are composed of a vacuum insulation panel body and a foamed polyurethane covering the outer periphery of the vacuum insulation panel body. The vacuum insulation panel includes a core material and a metal aluminum foil that is vacuum-sealed and wrapped around the core material to prevent damage. The core material can be ultra-fine glass fiber or fumed silica. The aluminum foil wrapping further enhances the protective performance and improves the overall aesthetics. A vacuum insulation panel is also installed on the top of the chamber, effectively isolating heat generated by thermal radiation. The vacuum insulation panel of this invention has a thermal conductivity only one-tenth that of ordinary rock wool, and the use of polyurethane foam and aluminum foil wrapping provides excellent thermal insulation.

[0034] like Figure 5As shown, to facilitate the maintenance and replacement of the aluminum-plastic composite panel 3, the aluminum-plastic composite panel 3 is fixed to the inner side of the cabin frame 1 by a flexible metal clip 11, and the metal clip 11 itself also has counter-teeth that can reliably fix the aluminum-plastic composite panel 3. The front part of the metal clip 11 adopts a rounded corner structure to press the aluminum-plastic composite panel 3 tightly, and also facilitates the installation of the aluminum-plastic composite panel 3.

[0035] Specifically, the aluminum composite panel 3 of the interior wall decoration of the prefabricated cabin body is fixed with metal clips 11. The metal clips 11 are triangular clips. After cutting a notch on one side of the aluminum composite panel 3, it is bent at 90 degrees and inserted into the metal clips 11. When inspecting or replacing the aluminum composite panel 3, the aluminum composite panel 3 can be removed using a suction cup.

[0036] Furthermore, the aluminum-plastic composite panel 3 is a composite material, with aluminum as the main body and polyethylene as the filling material. The advantages of such a composite material are: it has excellent peel strength, is easy to process, and has excellent fire resistance. The aluminum-plastic composite panel 3 itself has various appearances and does not require painting, reducing processing and production time.

[0037] like Figure 2 As shown, in order to facilitate the laying of insulation materials and vacuum insulation panels, while ensuring its own rigidity and strength, the cabin frame 1 includes multiple columns 100 arranged around the perimeter, as well as crossbeams 101 and reinforcing beams 102. Multiple horizontally arranged crossbeams 101 are provided between two adjacent columns 100 from top to bottom, and reinforcing beams 102 are arranged at an incline to strengthen the connection between two adjacent columns 100.

[0038] Furthermore, the crossbeam 101 is a channel steel, and the reinforcing beam 102 is a C-shaped channel steel. Both the C-shaped channel steel and the channel steel are open-type channel steel, which facilitates the anti-corrosion spraying operation, ensures that there are no dead corners in the paint anti-corrosion, and simplifies the paint construction process.

[0039] Furthermore, such as Figure 2 As shown, in order to facilitate the fixing of the exterior wall panel, the exterior wall panel 5 is fixed to the reinforcing beam 102 by the exterior wall fixing plate 10, and the exterior wall panel 5 is fixed to the exterior wall fixing plate 10 by countersunk screws, and the exterior wall fixing plate 10 is welded and fixed to the reinforcing beam 102.

[0040] like Figure 6 As shown, the outermost surface of the cabin frame 1 is provided with multiple spliced ​​outer wall panels 5, and adjacent outer wall panels 5 are connected by H-shaped connectors 12.

[0041] Furthermore, the exterior wall panel 5 is a fiber-reinforced cement board, which is made of non-metallic material.

[0042] In order to achieve a reliable connection between two adjacent exterior wall panels 5 and to achieve waterproofing, the opening of the H-type connector 12 (H-type aluminum profile) is used to insert the exterior wall panel 5, and waterproof structural adhesive is pre-applied to the corner of the H-type aluminum profile before inserting it into the exterior wall panel 5.

[0043] Specifically, countersunk holes are drilled in the exterior wall panel 5, and then bolts are used to fix the exterior wall panel 5 to the exterior wall fixing plate 10. Two adjacent exterior wall panels 5 are inserted into the notches of the H-shaped aluminum profile to achieve the connection between the two. The sealant is used to ensure the sealing of the connection between the two to prevent water leakage. In addition, the exterior wall panel 5 is a non-metallic material and will not rust.

[0044] like Figure 3 As shown, in order to limit the upper and lower ends of the vacuum insulation panel and facilitate the maintenance or replacement of the vacuum insulation panel, the cabin frame 1 is provided with multiple fixed guide rails 103. The upper and lower ends of the first vacuum insulation panel 2 are respectively slidably engaged with the corresponding fixed guide rails 103. Specifically, the vacuum insulation panel is slidable using the fixed guide rails 103, which facilitates the installation and replacement of materials.

[0045] Furthermore, such as Figure 2 , 3 As shown, each crossbeam 101 on the cabin frame 1 is provided with a fixed guide rail 103 at its top and bottom. A first vacuum heat insulation plate 2 is provided between adjacent crossbeams 101, and the upper and lower ends of the first vacuum heat insulation plate 2 are respectively slidably engaged with the corresponding fixed guide rail 103.

[0046] Specifically, when installing the first vacuum insulation panel, first securely fix the lower fixed guide rail 103, insert the vacuum insulation panel into the fixed guide rail 103, and then fasten and fix the upper fixed guide rail 103 to achieve the connection between the two.

[0047] Preferably, the connection between the two fixed guide rails 103 needs to ensure assembly accuracy and ensure no height difference, so that the vacuum insulation plate can move smoothly on the fixed guide rails 103, and the fixed guide rails at the ends can be easily removed to ensure that the vacuum insulation plate can be easily removed and replaced.

[0048] like Figure 4 As shown, the second vacuum insulation plate 8 is fixed to the inner side of the cabin top frame 6 by sheet metal parts 13.

[0049] Furthermore, the fixed guide rail 103 and sheet metal part 13 can be selected as standard parts, which can further avoid damage to the vacuum insulation plate. The standard profile can be fixed by welding. Of course, it can also be made of steel plate with a thickness of not less than 2mm and bent, and can be fixed to the frame by bolts or welding.

[0050] To prevent the top from rusting and extend the service life of the cabin, the top plate 7 of the cabin roof is made of stainless steel.

[0051] Furthermore, the cabin insulation layer 4 and the cabin roof insulation layer 9 of the present invention can be made of rock wool or polyurethane.

[0052] The vacuum insulation panels of this invention are reliably connected and fixed within the prefabricated cabin body and roof, ensuring the overall thermal insulation performance of the prefabricated cabin. Furthermore, the vacuum insulation panels laid on the cabin body can be easily removed via sliding rails for convenient maintenance and replacement. In addition, the enhanced insulation performance reduces air conditioning power consumption, and condensation due to cold bridging is eliminated inside the cabin.

[0053] The cabin and roof of this invention not only have an insulation layer, but also have vacuum insulation panels laid on the frame. The insulation material and the vacuum insulation panels do not interfere with each other. The advantages of this design are: First, the thermal insulation performance of the prefabricated cabin is achieved through the combination of the insulation layer and the vacuum insulation panels, greatly improving the insulation effect. Second, with the simultaneous laying of the insulation layer and vacuum insulation panels, the situation where insulation material cannot be properly laid on some steel sections due to structural reasons, as seen in existing technologies, is avoided. This invention ensures full insulation coverage of the cabin and roof, eliminating any insulation dead zones, meeting insulation requirements, and better isolating external heat. Condensation due to cold bridges will also be eliminated inside the cabin, ensuring the normal operation of the equipment. Simultaneously, the cooling energy generated by the industrial air conditioner can be stored inside the cabin, thereby reducing air conditioning energy consumption and extending the service life of the air conditioner.

[0054] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
