Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to an assembled box-type transformer roof. Background Art

[0002] European-style box-type transformers (box-type substations) are outdoor complete substations that are widely used in urban power distribution, industrial plants, and new energy projects. Their box structures must meet the requirements of protection, durability, and large-scale operation.

[0003] Traditional box-type substation roofs are typically manufactured using a split-piece welding process: small panels are spliced ​​together and then welded together to form a single, integrated roof to meet waterproofing requirements. However, this type of box-type substation roof must be broken down into multiple small components, sealed through continuous, full-length welding to avoid the risk of leakage caused by spot welding. The welding process requires precise alignment, is time-consuming and labor-intensive, and relies on highly skilled welders. Furthermore, large welded roofs require an entire spray coating for corrosion protection, making the overall structure bulky after welding. However, due to equipment limitations, most spray booths and ovens cannot accommodate components larger than 12 square meters, making surface treatment difficult. This necessitates outdoor hand-painting, resulting in uneven coating, poor adhesion, and the release of volatile organic compounds (VOCs), which pollute the environment. Furthermore, while full-length welding ensures sealing, welds are prone to defects such as pores, slag inclusions, and cracks, increasing the risk of leakage due to thermal stress or vibration over long-term use. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a modular box-type substation roof that can be easily assembled, improves processing and production efficiency, and ensures good sealing after assembly. The technical solution adopted is as follows:

[0005] An assembled box-type transformer roof is characterized in that it includes a plurality of roof splicing units arranged closely in sequence from left to right; in two adjacent roof splicing units on the left and right, the right end of the left roof splicing unit contacts and cooperates with the left end of the right roof splicing unit and is connected through a splicing assembly, each splicing assembly includes a splicing cover and two splicing plates, the two splicing plates are respectively arranged on the bottoms of the two adjacent roof splicing units, and the ends of the two splicing plates close to each other are provided with downwardly bent vertical connecting parts, the two vertical connecting parts are in sealed contact and connected by a first detachable connecting structure; the splicing cover is arranged on the lower side of the two splicing plates and covers the two vertical connecting parts, and the left end and the right end of the splicing cover are respectively connected to the corresponding splicing plates through a second detachable connecting structure.

[0006] The above-mentioned assembled box-type transformer roof is formed by splicing a plurality of roof splicing units in sequence from left to right, disassembling the roof into standardized small components, adapting to conventional panel sizes, shortening the design cycle and supporting flexible production. Since each roof splicing unit can be sprayed before being assembled as a whole, the surface treatment difficulty is low, which can improve processing and production efficiency. Two adjacent roof splicing units are connected by a splicing assembly, and the two splicing plates of the splicing assembly are respectively arranged on the bottom of the two roof splicing units, and the vertical connection parts of the two splicing plates are connected by a first detachable connection structure, and the left and right ends of the splicing cover are respectively connected to the corresponding splicing plates by a second detachable connection structure. It is not only convenient to assemble, but also can effectively strengthen the connection between the two roof splicing units, ensuring that the connection between the two is relatively tight and reliable. When it rains, due to the sealed contact between the vertical connection parts of the two splicing plates, the splicing cover is arranged on the lower side of the two splicing plates and covers the two vertical connection parts, thereby preventing water leakage at the splicing of two adjacent roof splicing units. Even if a small amount of water penetrates into the splicing of the roof panels, the water droplets will drip along the vertical connection parts of the two splicing plates, thereby ensuring that the water droplets flow along the splicing cover to the eaves of the roof and drip onto the outside of the box transformer, rather than dripping onto the electrical equipment inside the box transformer.

[0007] As a preferred embodiment of the present invention, both vertical connecting portions are provided with a plurality of first connecting through-holes arranged sequentially from front to back, with the number of first connecting through-holes on the two vertical connecting portions being the same and their positions corresponding to each other. The first detachable connecting structure comprises a plurality of bolt connection structures arranged sequentially from front to back, each bolt connection structure connecting two corresponding first connecting through-holes. This structure allows the multiple bolt connection structures to securely connect different portions of the two vertical connecting portions, making the overall connection more secure and improving assembly efficiency.

[0008] As a further preferred embodiment of the present invention, the bolt connection structure includes a fixing bolt and a fixing nut. The screw of the fixing bolt passes through the two first connecting through holes corresponding to the positions on the two splicing plates in sequence. The fixing nut is installed on the screw of the fixing bolt. The fixing nut and the head of the fixing bolt jointly clamp the corresponding parts of the two splicing plates.

[0009] As a preferred solution of the present invention, a seal is provided between the two vertical connecting parts, which can completely seal the gap between the two vertical connecting parts to prevent water droplets from entering the interior of the box-type transformer through the gap between the two vertical connecting parts.

[0010] As a preferred solution of the present invention, the splicing cover is made of stiffening plates, thereby making the splicing cover as a whole have better structural stability.

[0011] As a preferred embodiment of the present invention, the splicing cover includes a horizontal plate, two side longitudinal plates, and two connecting plates. The lower edges of the two side longitudinal plates are integrally connected to the left and right edges of the horizontal plate, and the inner edges of the two connecting plates are integrally connected to the upper edges of the corresponding side longitudinal plates. The two connecting plates are respectively connected to the corresponding splicing plates via the second detachable connecting structure. The two vertical connecting parts are located in a groove formed by the horizontal plate and the two side longitudinal plates. When the splicing cover needs to be installed on the lower side of the two splicing plates, the two connecting plates can be connected to the two splicing plates together via the second detachable connecting structure to achieve fixation. The two vertical connecting parts are located in the groove formed by the horizontal plate and the two side longitudinal plates, thereby covering the two vertical connecting parts and further preventing water leakage at the splicing point of two adjacent roof splicing units.

[0012] As a further preferred embodiment of the present invention, the connecting plate is provided with a plurality of second connecting through-holes arranged sequentially from front to back; the second detachable connecting structure includes a plurality of studs and a plurality of locking nuts, the upper end of each stud being connected to the splicing plate, the lower end of each stud passing through a corresponding second connecting through-hole, and each locking nut being mounted on a corresponding stud, the locking nut and the corresponding splicing plate jointly clamping the corresponding connecting plate. Thus, the two connecting plates of the splicing cover can be locked to the two splicing plates through the engagement between each locking nut and each stud, facilitating assembly.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) This assembled box-type substation roof disassembles the roof into standardized small components that are suitable for conventional panel sizes. This not only shortens the design cycle and supports flexible production, but also facilitates the rapid design and production of box-type substation roofs of various sizes.

[0015] (2) This assembled box-type roof disassembles the roof into standardized small components, which can be assembled as a whole after spraying, avoiding the limitations of large equipment, improving processing and production efficiency, and at the same time improving coating quality and reducing pollution;

[0016] (3) This assembled box-type substation roof is equipped with a splicing structure with good sealing performance between two adjacent roof splicing units, which can not only ensure that the connection between the two adjacent roof splicing units is relatively firm and reliable, but also replace full welding waterproofing, overcome the problem of possible leakage caused by welding, solve the hidden danger of leakage in the assembly joints, and effectively prevent water from dripping onto the power equipment inside the box-type substation.
