Description

Technical Field

[0001] This utility model relates to the field of prefabricated cabin technology, and more specifically, to an electrical prefabricated cabin roof with a flow guiding structure. Background Technology

[0002] As modular integrated equipment compartments, prefabricated modules have long faced the challenge of balancing drainage efficiency and structural strength in their roof structures, especially in high-temperature, high-humidity, and rainy / snowy application scenarios (such as coastal substations and mountain photovoltaic power stations). 1. Risk of condensation caused by water accumulation on the roof: Traditional prefabricated cabin roofs are mostly flat or have a low slope (slope < 2°). During heavy rain or snowmelt, water can remain for more than 30 minutes. The stagnant water creates a continuous temperature difference between itself and the cabin interior (measured at ≥ 5°C), causing water vapor to condense on the inner wall of the roof, which over time leads to metal corrosion and a decline in electrical insulation. 2. Lack of drainage diversion structure leads to inefficient drainage: Current technologies rely on gravity for natural drainage and lack active diversion mechanisms. - Flat roofs are prone to clogging of drainage holes due to dust accumulation, resulting in a drainage efficiency reduction of >40%; - Although the slope of a few sloping roofs has been increased (>10°), no drainage channels have been designed, resulting in disordered water flow and local water accumulation depths of more than 10mm. 3. The contradiction between structural strength and drainage function: Excessively increasing the roof slope (e.g., >10°) or reducing the material thickness to improve drainage efficiency will result in: - The risk of roof deformation increases when snow load is ≥0.8kN / m²; - The exposed metal support beams create thermal bridges, exacerbating condensation (local temperature differences reach 3℃-5℃). Therefore, in fields such as power and new energy where the environmental reliability requirements for equipment are stringent, there is an urgent need for a prefabricated cabin roof with an integrated flow-guiding structure to achieve directional and rapid drainage while ensuring load-bearing capacity, thereby blocking the conditions for condensation formation at the source. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides an electrical prefabricated cabin roof with a flow guiding structure, which has the advantage of facilitating drainage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electrical prefabricated cabin roof with a flow guiding structure, comprising a base, a prefabricated cabin body bolted to the top of the base, an anti-condensation structure above the prefabricated cabin body, the anti-condensation structure comprising a top plate welded to the top of the prefabricated cabin body, a support frame and a reinforcing frame welded to the top of the top plate, an aluminized zinc-coated steel plate welded to the top of the support frame and the reinforcing frame, the width of the aluminized zinc-coated steel plate being greater than the length of the prefabricated cabin body, drainage grooves uniformly formed on the surface of the aluminized zinc-coated steel plate, drainage slopes uniformly formed on both sides of the drainage grooves on the surface of the aluminized zinc-coated steel plate, and inclined surfaces formed on the inner sides of both ends of the aluminized zinc-coated steel plate.

[0005] As a preferred technical solution of this utility model, a reinforcing frame is uniformly and vertically welded between the inner sides of the first support frame and the second support frame, the inner ends of the first support frame and the second support frame are welded to each other, and the inclined surfaces of the first support frame and the second support frame are in contact with the bottom side of the aluminum-zinc coated steel plate.

[0007] As a preferred embodiment of this utility model, the outer side of the side plate is designed with a slope, and the length of the side plate is equal to the width of the aluminum-zinc coated steel plate.

[0008] As a preferred technical solution of this utility model, the distance between the outermost end of the side plate and the prefabricated cabin is equal to the distance between the two ends of the aluminum-zinc coated steel plate and the prefabricated cabin, and the interior of the aluminum-zinc coated steel plate is provided with polyurethane foam.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves efficient and directional drainage of accumulated water through the coordinated design of the top drainage channel and the drainage slope, completely solving the problem of condensation caused by the large temperature difference between the inside and outside due to water retention in traditional solutions.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1 to 6As shown, this utility model provides an electrical prefabricated cabin roof with a flow guiding structure, including a base 1, a prefabricated cabin 2 bolted on the top of the base 1, an anti-condensation structure 3 on the top of the prefabricated cabin 2, the anti-condensation structure 3 including a top plate 301 welded on the top of the prefabricated cabin 2, a support frame 308 and a reinforcing frame 309 welded on the top plate 301, an aluminum-zinc coated steel plate 302 welded on the top of the support frame 308 and the reinforcing frame 309, the width of the aluminum-zinc coated steel plate 302 being greater than the length of the prefabricated cabin 2, drainage grooves 311 uniformly formed on the surface of the aluminum-zinc coated steel plate 302, drainage slopes 312 uniformly formed on both sides of the drainage grooves 311 on the surface of the aluminum-zinc coated steel plate 302, and inclined surfaces 313 formed on the inner sides of both ends of the aluminum-zinc coated steel plate 302.

[0015] Support frame two (310) is welded to both sides along the length of the top plate (301) and is parallel to support frame one (308). The two form a rectangular grid load-bearing skeleton through the reinforcing frame (309).

[0016] The top plate 301 has a square plate 304 bolted to both outer sides at both ends. A square plate 305 is welded to the front end of the square plate 304. The surface of the square plate 305 has a second mounting hole 307. The surface of the square plate 304 has a first mounting hole 306. The front end of the galvanized steel plate 302 has a side plate 303 bolted to it. The inner sides of both ends of the side plate 303 are bolted to the outer sides of the square plate 305 through the second mounting hole 307. The outer side of the side plate 303 is designed with a slope. The length of the side plate 303 is equal to the width of the galvanized steel plate 302. The distance between the outermost end of the side plate 303 and the prefabricated cabin 2 is equal to the distance between the two ends of the galvanized steel plate 302 and the prefabricated cabin 2. The interior of the galvanized steel plate 302 is filled with polyurethane foam. Polyurethane foam material is injected under high pressure into the cavity between the aluminum-zinc coated steel plate 302 and the top plate 301 to form a continuous insulation layer; all joints are filled with polyurethane sealant to ensure no thermal bridges.

[0017] The prefabricated cabin 2 is bolted to the base 1, and the top plate 301 is welded to the top of the prefabricated cabin 2 as the base plate of the anti-condensation structure. The support frame of the anti-condensation structure 3 is welded to the top of the top plate 301, which consists of support frame 1 308, support frame 2 310, and reinforcing frame 309, forming a grid-like load-bearing skeleton. Aluminized zinc steel plate 302 is welded above support frame 1 308 and support frame 2 310 to form an eaves-type anti-overflow structure. Drainage grooves 311 and drainage slopes 312 are processed on the surface of the aluminized zinc steel plate 302. The outer side of the side plate 303 is designed as a slope, which connects with the inclined surface 313 of the aluminized zinc steel plate 302 to guide water flow to drain along both sides of the cabin. All joints are filled with polyurethane foam. Polyurethane foam is injected into the interior of the aluminized zinc steel plate 302 to achieve heat preservation and sealing. Meltwater flows through the drainage slope 312 and inclined surface 313 into the drainage groove 311 and is then quickly discharged to avoid leakage.

[0018] The slope of the drainage slope 312 has an inclination angle of 3°-5°, the width of the drainage channel 311 is 5-8mm, and the spacing between channels is 100-150mm, ensuring that the accumulated water is discharged in a directional manner along the inclined surface 313.

[0019] Through the coordinated design of the top drainage channel 311 and the drainage slope 312, efficient and directional drainage of accumulated water is achieved, completely solving the problem of condensation caused by large temperature differences between the inside and outside due to water retention in traditional solutions. At the same time, it does not rely on high-energy-consuming equipment, significantly improving safety and durability. Through the integrated drainage slope 312 and reinforced frame design, the top load-bearing capacity is enhanced while ensuring rapid drainage, adapting to extreme environments such as snow accumulation and heavy rain. The overall sealing and insulation performance is excellent, greatly reducing maintenance costs.

[0020] Among them, a reinforcing frame 309 is uniformly and vertically welded between the inner sides of support frame 1 308 and support frame 2 310. The inner ends of support frame 1 308 and support frame 2 310 are welded to each other. The inclined surfaces of support frame 1 308 and support frame 2 310 are in contact with the bottom side of galvanized steel plate 302.

[0021] By vertically welding the reinforcing frame 309 to the support frame 308 and the support frame 310, a triangular or rectangular grid structure is formed. This design evenly distributes the top load to the entire cabin frame, avoids local stress concentration, and improves the resistance to deformation. Through this design, the reinforcing frame 309 solves the contradiction between structural strength and drainage efficiency without adding extra weight.

[0022] Working principle and usage process of this utility model: The prefabricated cabin 2 is bolted to the base 1, and the top plate 301 is welded to the top of the prefabricated cabin 2 as the base plate of the anti-condensation structure. The support frame of the anti-condensation structure 3 is welded to the top of the top plate 301, which consists of support frame 1 308, support frame 2 310, and reinforcing frame 309, forming a grid-like load-bearing skeleton. Aluminized zinc steel plate 302 is welded above support frame 1 308 and support frame 2 310 to form an eaves-type anti-overflow structure. Drainage grooves 311 and drainage slopes 312 are processed on the surface of the aluminized zinc steel plate 302. The outer side of the side plate 303 is designed as a slope, which connects with the inclined surface 313 of the aluminized zinc steel plate 302 to guide water flow to drain along both sides of the cabin. All joints are filled with polyurethane foam. Polyurethane foam is injected into the interior of the aluminized zinc steel plate 302 to achieve heat preservation and sealing. Meltwater flows through the drainage slope 312 and inclined surface 313 into the drainage groove 311 and is then quickly discharged to avoid leakage.
