Description

Technical Field

[0001] This utility model relates to the field of modular prefabricated cabin technology, and in particular to a waterproof structure for the roof of a modular prefabricated cabin. Background Technology

[0002] With the rapid development of smart grids, the layout of secondary equipment in power systems is undergoing a transformation. Typically, secondary equipment is installed in the main control room of power plants or substations, with control panels arranged according to voltage levels. However, the construction and development of smart grids require the rapid establishment of integrated control for secondary equipment, enabling the comprehensive reflection of monitoring, scheduling, and operational data from primary equipment on remote computers for remote monitoring and dispatching.

[0003] To meet this demand, secondary equipment has begun to adopt a modular design, allowing for prefabrication in the factory and subsequent on-site installation. This type of prefabricated modular unit is valued by users and manufacturers for its flexibility and efficiency. The design of the prefabricated unit needs to consider the shape of the primary equipment inside, the installation method, and limitations of road transport conditions. After the primary and secondary equipment are commissioned in the factory, the prefabricated unit can be transported to the site as a whole or disassembled into several unit modules, where they are assembled to form a complete unit. During this process, the modular prefabricated unit needs sufficient mechanical strength to withstand the pressure of transportation, lifting, and assembly. Furthermore, after assembly, the prefabricated unit must not only maintain its overall strength but also ensure that the joints effectively prevent rainwater from entering the unit, protecting the internal equipment from damage.

[0004] The existing prefabricated cabin structure has some defects, mainly in the poor waterproof performance of the top cover, which leads to low reliability and a large amount of maintenance work. In addition, water leakage at the joints may cause short circuit accidents in live equipment, increasing safety hazards.

[0005] Therefore, improving the waterproof performance of the top cover is an urgent problem that needs to be solved. Utility Model Content

[0036] With the rapid development of smart grids, the layout of secondary equipment in power systems is undergoing a transformation. Typically, secondary equipment is installed in the main control room of power plants or substations, with control panels arranged according to voltage levels. However, the construction and development of smart grids require the rapid establishment of integrated control for secondary equipment, enabling the comprehensive reflection of monitoring, scheduling, and operational data from primary equipment on remote computers for remote monitoring and dispatching.

[0037] To meet this demand, secondary equipment has begun to adopt a modular design, allowing for prefabrication in the factory and subsequent on-site installation. This type of prefabricated modular unit is valued by users and manufacturers for its flexibility and efficiency. The design of the prefabricated unit needs to consider the shape of the primary equipment inside, the installation method, and limitations of road transport conditions. After the primary and secondary equipment are commissioned in the factory, the prefabricated unit can be transported to the site as a whole or disassembled into several unit modules, where they are assembled to form a complete unit. During this process, the modular prefabricated unit needs sufficient mechanical strength to withstand the pressure of transportation, lifting, and assembly. Furthermore, after assembly, the prefabricated unit must not only maintain its overall strength but also ensure that the joints effectively prevent rainwater from entering the unit, protecting the internal equipment from damage.

[0038] The existing prefabricated cabin structure has some defects, mainly in the poor waterproof performance of the top cover, which leads to low reliability and a large amount of maintenance work. In addition, water leakage at the joints may cause short circuit accidents in live equipment, increasing safety hazards.

[0039] After careful examination, the applicant discovered that existing prefabricated modules generally use a double-sloped roof structure to prevent water and snow accumulation, but their waterproofing performance is poor. External rainwater may seep into the module through roof gaps, damaging the electrical equipment inside and posing a safety hazard. This also increases subsequent maintenance work and seriously affects the safety and reliability of the prefabricated module. Furthermore, due to the insufficient mechanical strength and rigidity of the unitized prefabricated modules, deformation may occur during lifting, transportation, and installation, which also affects the waterproofing performance of the prefabricated module.

[0040] The main objective of this invention is to propose a combined prefabricated cabin roof waterproof structure to address the problem of how to improve the waterproof performance of the roof.

[0041] Please see Figures 1 to 3 In one embodiment of this utility model, the combined prefabricated cabin roof waterproof structure 100 includes a first roof 1, a second roof 2, a first supporting bend plate 3, a second supporting bend plate 4, and a protective shell 5. The first supporting bend plate 3 includes a first supporting plate 31 and a first bend plate 32. The second supporting bend plate 4 includes a second supporting plate 41 and a second bend plate 42. The two ends of the first supporting plate 31 are respectively connected to the first bend plate 32 and the side of the first roof 1 facing the second roof 2. The two ends of the second supporting plate 41 are respectively connected to the side of the second bend plate 42 and the side of the second roof 2 facing the first roof 1. The first supporting plate 31 is connected to the second supporting plate 41. The first roof 1, the second roof 2, and the protective shell 5 form a first receiving cavity 51. The first supporting bend plate 3 and the second supporting bend plate 4 are both located in the first receiving cavity 51, and the first bend plate 32 and the second bend plate 42 abut against the cavity wall of the first receiving cavity 51.

[0042] In this embodiment of the invention, the first top cover 1 and the second top cover 2 are the top cover structures of the prefabricated cabin, used to cover the first cabin body 7 and the second cabin body 8. The first top cover 1 and the second top cover 2 are fixedly connected by a first support plate 31 provided on the first top cover 1 and a second support plate 41 provided on the second top cover 2, thereby enabling the assembly of the prefabricated cabin and protecting the internal equipment from the influence of the external environment. In this embodiment, the protective shell 5 is U-shaped. By setting the protective shell 5, the first top cover 1, and the second top cover 2 to form a first receiving cavity 51, the protective shell 5 can cover the outer walls of the first support bend plate 3 and the second support bend plate 4, enhancing the protection level at the cabin joint and helping to prevent rainwater from flowing from the first support plate. The joint between the first support plate 31 and the second support plate 41 enters the interior of the prefabricated cabin, thereby protecting the internal primary electrical equipment from external rainwater and preventing safety accidents. The end of the first support plate 31 away from the first top cover 1 is connected to the first curved plate 32, and the end of the second support plate 41 away from the second top cover 2 is connected to the second curved plate 42. By setting the first curved plate 32 and the second curved plate 42 to abut against the cavity wall of the first receiving cavity 51, moisture is prevented from seeping into the interior of the prefabricated cabin from the upper part of the first support plate 31 and the second support plate 41, which helps to improve waterproof performance. In addition, the first curved plate 32 and the second curved plate 42 can also provide necessary support for the protective shell 5, which helps to improve the structural stability and strength of the protective shell 5.

[0043] The technical solution of this utility model uses a protective shell 5 to form a first receiving cavity 51 with a first top cover 1 and a second top cover 2, so that the first supporting curved plate 3 and the second supporting curved plate 4 are both located inside the first receiving cavity 51. Furthermore, by setting the first curved plate 32 and the second curved plate 42 to abut against the cavity wall of the first receiving cavity 51, the protection level and structural strength of the unit prefabricated cabin at the joint of the cabin are enhanced. This helps to prevent rainwater from entering the interior of the prefabricated cabin from the joint of the first supporting plate 31 and the second supporting plate 41, thereby protecting the internal primary electrical equipment from the damage caused by external rainwater, avoiding safety accidents, improving the reliability and safety of the prefabricated cabin, reducing equipment failures and safety accidents caused by environmental factors, and ensuring the stable operation of the power system.

[0044] In this embodiment, the first top cover 1, the first support plate 31, and the first curved plate 32 can be integrally formed or welded together, thereby enhancing the strength and structural stability of the prefabricated cabin. This embodiment does not limit the connection method of the first top cover 1, the first support plate 31, and the first curved plate 32. Similarly, the second top cover 2, the second support plate 41, and the second curved plate 42 can be integrally formed or welded together, thereby enhancing the strength and structural stability of the prefabricated cabin. This embodiment does not limit the connection method of the second top cover 2, the second support plate 41, and the second curved plate 42. The first support plate 31 and the second support plate 41 can be detachably connected by bolts and nuts, or directly welded together. This embodiment does not limit the connection method of the first support plate 31 and the second support plate 41. The protective shell 5 can be riveted or welded to the first top cover 1 and the second top cover 2. This embodiment does not limit the connection method between the protective shell 5 and the first top cover 1 and the second top cover 2.

[0045] Please see Figure 4 and Figure 5 In one embodiment, the modular prefabricated cabin roof waterproof structure 100 further includes a protective cover 6. The first top cover 1 and the second top cover 2, together with the protective cover 6, form a second receiving cavity (not shown in the figure), and the protective shell 5 is located within the second receiving cavity. Specifically, the protective cover 6 is herringbone shaped. By setting the protective cover 6 together with the first top cover 1 and the second top cover 2 to form the second receiving cavity, the protective cover 6 and the protective shell 5 form a double waterproof structure. The protective cover 6 provides an additional waterproof layer for the prefabricated cabin, further enhancing the waterproof performance and ensuring the safety of the equipment inside the cabin under extreme weather conditions. The structure is reasonably laid out, with a high level of protection. Moreover, the addition of the protective cover 6 makes the appearance of the prefabricated cabin roof more neat and beautiful, improving the overall appearance and texture of the prefabricated cabin and meeting the aesthetic requirements of modern industrial design. The protective shell 5 is located within the second receiving cavity, so that the protective shell 5 is surrounded by the additional protective cover 6, thereby improving the level of protection and protecting the protective shell 5 from direct damage from the external environment, extending the service life of the protective shell 5.

[0046] In one embodiment, the protective cover 6 includes a protective member 61 and a clamping member 62. A first top cover 1 and a second top cover 2, together with the protective member 61, form a second receiving cavity. The clamping member 62 is connected to the protective member 61. A receiving groove 621 capable of accommodating a protective shell 5 is provided on the side of the clamping member 62 away from the protective member 61. The outer wall of the protective shell 5 abuts against the groove wall of the receiving groove 621. Specifically, in this embodiment, the protective member 61 is herringbone shaped, and the extension length of the protective member 61 is not less than the extension length of the protective shell 5. For ease of manufacturing, multiple protective members 61 can be sequentially spliced ​​together to form the second receiving cavity. Each protective component 61 is provided with two clamping components 62, which are spaced apart along the extension direction of the protective component 61. The groove walls of the receiving grooves 621 on the two clamping components 62 can abut against the outer wall of the protective shell 5, thereby providing additional support for the protective component 61 when subjected to external pressure such as rain, wind pressure or snow load (referring to the load generated by snow on the top cover structure), so as to enhance the overall stability and strength of the combined prefabricated cabin top cover waterproof structure 100. Moreover, the design of the clamping components 62 makes the installation and disassembly of the protective cover 6 more convenient, and facilitates the maintenance and repair of the equipment inside the protective cover 6. In this embodiment, each protective component 61 is provided with at least one clamping component 62. The specific number of clamping components 62 on each protective component 61 is not limited in this embodiment. The receiving groove 621 can accommodate part of the structure of the protective shell 5 or the entire structure of the protective shell 5, so that the clamping component 62 can clamp the protective shell 5 to increase the stability of the installation of the protective cover 6. This embodiment does not limit this. The protective component 61 can be riveted or welded to the first top cover 1 and the second top cover 2. This embodiment does not limit the connection method between the protective component 61 and the first top cover 1 and the second top cover 2.

[0047] In one embodiment, the protective component 61 includes a cover body 611, a first sealing plate 612, and a second sealing plate 613. A clamping member 62 is connected to the cover body 611. Both ends of the cover body 611 are respectively connected to the first sealing plate 612 and the second sealing plate 613. The cover body 611, the first top cover 1, the second top cover 2, the first sealing plate 612, and the second sealing plate 613 form a second receiving cavity. Specifically, the first sealing plate 612 and the second sealing plate 613 are used to seal both ends of the cover body 611, so that the protective cover 6, the first top cover 1, and the second top cover 2 form a complete closed structure, which helps to improve the prefabricated cabin. The sealing performance of the top cover prevents moisture and dust from entering the second accommodating cavity, reducing the risk of short circuits or equipment damage caused by the external environment, thereby improving the safety of the prefabricated cabin, reducing the long-term operation and maintenance costs of the prefabricated cabin, and enhancing the overall rigidity and strength of the protective cover 6, enabling it to withstand greater external pressures, such as rain, wind pressure, and snow loads, providing a strong guarantee for the long-term stable operation of the prefabricated cabin. Furthermore, the combined design of the cover body 611, the first sealing plate 612, and the second sealing plate 613 makes the appearance of the prefabricated cabin top cover neater and more uniform, improving the overall aesthetics of the prefabricated cabin.

[0048] In one embodiment, a first sealant layer (not shown) is provided on the protective shell 5. One side of the first sealant layer is connected to the groove wall of the first receiving cavity 51, and the other side of the first sealant layer is connected to the first bent plate 32 and the second bent plate 42; and / or, a second sealant layer (not shown) is provided on the protective shell 5. One side of the second sealant layer is connected to the outer wall of the protective shell 5, and the other side of the second sealant layer is connected to the groove wall of the receiving groove 621; specifically, by providing a first sealant layer between the protective shell 5 and the groove wall of the first receiving cavity 51, and by providing a sealant layer between the outer wall of the protective shell 5 and the receiving groove 621... The second sealant layer between the tank walls effectively prevents moisture from penetrating the joints, improving the waterproof performance of the prefabricated cabin roof. This reduces maintenance needs due to leakage, lowers maintenance costs and workload for the prefabricated cabin, and provides additional stability to the connection, reducing structural loosening caused by external impacts or vibrations, improving the sealing reliability of the connection, reducing the risk of seal failure due to environmental changes, and enhancing the safety and environmental adaptability of the combined prefabricated cabin roof waterproof structure 100. This provides a strong guarantee for the long-term stable operation of the prefabricated cabin.

[0049] In one embodiment, the prefabricated cabin roof waterproof structure 100 further includes a first reinforcing member (not shown) and a second reinforcing member (not shown). The first curved plate 32 and the first roof 1 are both connected to the first reinforcing member, and the second curved plate 42 and the second roof 2 are both connected to the second reinforcing member. Specifically, by providing the first and second reinforcing members, additional support is provided for the first support plate 31 and the second support plate 41, significantly improving the overall strength of the roof structure. The first and second reinforcing members can distribute and bear external forces on the roof structure, such as rainfall, wind pressure, and snow load, effectively ensuring the bending and deformation resistance of the cabin roof structure, improving the stability of the prefabricated cabin roof structure, and providing strong protection for the long-term stable operation of the prefabricated cabin. In this embodiment, the first reinforcing member can be a first channel steel, with both ends welded to the first curved plate 32 and the first roof 1, respectively. The second reinforcing member can be a second channel steel, with both ends welded to the second curved plate 42 and the second roof 2, respectively.

[0050] In one embodiment, the first top cover 1 includes a first main load-bearing beam (not shown), a first secondary load-bearing beam (not shown), and a first cover plate 11. The modular prefabricated cabin top cover waterproof structure 100 also includes a first cabin 7 and a second cabin 8, which are connected. The first main load-bearing beam is connected to the top of the first cabin 7. There are multiple first secondary load-bearing beams, which are spaced apart along the width direction of the first cabin 7. All the multiple first secondary load-bearing beams are connected to the first main load-bearing beam. The first cover plate 11 is connected to the first main load-bearing beam and the first secondary load-bearing beam. The load-bearing beams are connected; the second top cover 2 includes a second main load-bearing beam (not shown), a second secondary load-bearing beam (not shown), and a second cover plate 21. The second main load-bearing beam is connected to the top of the second compartment 8. There are multiple secondary load-bearing beams, which are spaced apart along the width of the second compartment 8. All secondary load-bearing beams are connected to the second main load-bearing beam. The second cover plate 21 is connected to the second main load-bearing beam and the second secondary load-bearing beam. The end of the first support plate 31 away from the first curved plate 32 is connected to the side of the first cover plate 11 facing the second cover plate 21. One end of the support plate 41 away from the second curved plate 42 is connected to the side of the second cover plate 21 facing the first cover plate 11. The first cover plate 11 and the second cover plate 21, together with the protective shell 5, form a first receiving cavity 51. Specifically, in this embodiment, the prefabricated cabin is formed by splicing the first cabin body 7 and the second cabin body 8 together. The first cabin body 7 is equipped with primary equipment, and the second cabin body 8 is provided with a front maintenance passage for the maintenance of the primary equipment. The first cabin body 7 and the second cabin body 8 are transported to the site as independent units and then spliced ​​together on site to form a prefabricated cabin. The prefabricated cabin is constructed as a single unit. In this embodiment, by setting a first main load-bearing beam and a second main load-bearing beam, as well as multiple first secondary load-bearing beams and second secondary load-bearing beams, a stable frame is provided for the roof structure. This helps to distribute the stress in the roof structure more evenly, reduces local stress concentration, extends the service life of the roof structure, and significantly enhances the load-bearing capacity of the roof structure. This ensures the overall strength and bending and deformation resistance of the prefabricated cabin roof, enabling the roof structure to withstand greater loads and helping to maintain the stability of the roof structure under external forces. Furthermore, to improve the strength and stability of the roof structure, the first main load-bearing beam can be welded to the first secondary load-bearing beam, and the second main load-bearing beam can be welded to the second secondary load-bearing beam.

[0051] In this embodiment, the first compartment 7 and the second compartment 8 can be detachably connected by bolts and nuts, or they can be directly welded together. This embodiment does not limit the connection method of the first compartment 7 and the second compartment 8.

[0052] In one embodiment, the prefabricated modular roof waterproof structure 100 further includes a first connecting plate (not shown), a first thermal insulation and fireproof layer (not shown), a second connecting plate (not shown), and a second thermal insulation and fireproof layer (not shown). The first connecting plate is connected to the first main load-bearing beam, the first thermal insulation and fireproof layer is connected to the first connecting plate, the second connecting plate is connected to the second main load-bearing beam, and the second thermal insulation and fireproof layer is connected to the second connecting plate. Specifically, by setting the first thermal insulation and fireproof layer and the second thermal insulation and fireproof layer, the roof structure achieves thermal insulation and fireproofing. The fire resistance has been significantly improved, which helps maintain stable internal temperature, reduces energy consumption, and also improves the fire resistance rating of the top cover structure. This helps protect the equipment inside the compartment in the event of a fire and reduces the threat of fire to equipment and personnel safety. The first connecting plate is connected to the first main load-bearing beam, providing an additional fixing point for the first thermal insulation and fireproof layer. The second connecting plate is connected to the second main load-bearing beam, providing an additional fixing point for the second thermal insulation and fireproof layer. This simplifies the installation process of the top cover structure and facilitates the maintenance or replacement of the first and second thermal insulation and fireproof layers. In this embodiment, the first thermal insulation and fireproof layer and the second thermal insulation and fireproof layer can be made of silicate rock wool sandwich color steel plate or other materials with thermal insulation and fireproof properties. This embodiment does not limit the specific materials of the first thermal insulation and fireproof layer and the second thermal insulation and fireproof layer; and the first connecting plate can be riveted to the first main load-bearing beam, the first thermal insulation and fireproof layer can be riveted to the first connecting plate, the second connecting plate can be riveted to the second main load-bearing beam, and the second thermal insulation and fireproof layer can be riveted to the second connecting plate, thereby improving the strength and stability of the combined prefabricated cabin roof waterproof structure 100.

[0053] In one embodiment, the first cover plate 11 includes a first plate 111 and a first drip portion 112, and the second cover plate 21 includes a second plate 211 and a second drip portion 212. The end of the first support plate 31 away from the first curved plate 32 is connected to the side of the first plate 111 facing the second plate 211. The end of the second support plate 41 away from the second curved plate 42 is connected to the side of the second plate 211 facing the first plate 111. The first plate 111 and the second plate 211, together with the protective shell 5, form a first receiving cavity 51. The first drip portion 112 is disposed on the side of the first plate 111 away from the second plate 211 and on both sides of the first plate 111 along its extending direction, forming a first cavity (not shown). The second drip portion 212 is disposed on the side of the second plate 211 away from the first plate 111 and on both sides of the second plate 211 along its extending direction, forming a second cavity (not shown). The first chamber 7 and the second chamber 8 form a receiving space (not shown), and the first cavity... Both the first and second cavities are connected to the accommodating space. The first dripping part 112 has a first ventilation hole (not shown) connected to the first cavity on the side facing the first cabin 7, and the second dripping part 212 has a second ventilation hole (not shown) connected to the second cavity on the side facing the second cabin 8. Specifically, after the first cabin 7 and the second cabin 8 are assembled, the first dripping part 112 and the second dripping part 212 can surround the top cover structure. The first dripping part 112 and the second dripping part 212 help guide rainwater down the top cover of the prefabricated cabin, reduce the accumulation of rainwater on the surface of the top cover, and reduce the risk of leakage. By setting the first ventilation hole and the second ventilation hole, the ventilation between the accommodating space inside the prefabricated cabin and the external environment is enhanced, which helps to regulate the temperature and humidity inside the cabin and reduce the generation of condensate. Moreover, the first dripping part 112, the second dripping part 212, the first ventilation hole and the second ventilation hole can be adjusted according to the specific needs and size of the prefabricated cabin to adapt to different installation environments and conditions.

[0054] In one embodiment, the first cover plate 11 includes a plurality of first plates 111 that overlap sequentially, and the second cover plate 21 includes a plurality of second cover plates 21 that overlap sequentially. Specifically, since the prefabricated cabin is large in size, the first cover plate 11 can be formed by overlapping multiple first plates 111 sequentially, and the second cover plate 21 can be formed by overlapping multiple second plates 211 sequentially. The specific number and size of the first plates 111 and the second plates 211 can be selected according to actual needs, thereby improving the flexibility and adaptability of the prefabricated cabin manufacturing. The form of overlapping multiple first plates 111 and multiple second plates 211 sequentially can reduce the path of rainwater infiltration. Each overlap becomes a key point for waterproofing, thereby improving the overall waterproofing effect. The overlapping structure can increase the rigidity and strength of the first cover plate 11 and the second cover plate 21, enabling the top cover structure to withstand greater external loads. It can also make the installation of the first cover plate 11 and the second cover plate 21 simpler. The plates can be overlapped together in sequence. During maintenance, damaged plates can be replaced individually without replacing the entire cover plate structure. In this embodiment, to ensure the strength and stability of the top cover structure, both the first plate 111 and the second plate 211 can be made of cold-rolled steel plates. The two adjacent cold-rolled steel plates overlap by 30mm at the joint, and after the two adjacent cold-rolled steel plates are welded, container-specific sealant can be applied to the joint to enhance the seal at the joint and prevent rainwater from entering the cabin.

[0055] In this embodiment, to enhance the waterproof rating of the top cover structure, a protective shell 5 can be installed at the joint where two adjacent cold-rolled steel plates overlap, thereby enhancing the waterproof rating at the joint of the top cover structure. This helps prevent rainwater from entering the interior of the prefabricated cabin from the joint, thus protecting the internal primary electrical equipment from external rainwater damage, avoiding safety accidents, and improving the reliability and safety of the prefabricated cabin.
