Description

Technical Field

[0001] This utility model relates to the field of substations, and in particular to a prefabricated substation top cover fixing structure. Background Technology

[0002] Prefabricated substations, due to the large size and weight of their internal equipment, typically feature removable top covers for ease of installation. The internal equipment is installed via hoisting, and these top covers are usually secured with internal bolts. This requires reserving space for personnel during installation, leading to inefficient use of internal space and difficulty in achieving even distribution of equipment. This is especially problematic for large prefabricated substations, where uneven fixing can easily cause top cover seal failure. Therefore, developing a superior top cover fixing structure for prefabricated substations has become a pressing issue for those skilled in the art. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated substation top cover fixing structure to solve the problem that the existing substation top cover fixing methods are all internal bolt fixing methods, which require reserving personnel installation positions during installation, making it impossible to effectively utilize the internal space.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a prefabricated substation top cover fixing structure, including a top cover and fixing points. The top cover is disposed at the top of the wall, and the lower surface of the top cover is detachably connected to the outer surface of the wall through several evenly arranged fixing points. The fixing points include a bending plate, a support plate, and a locking round steel. The top of the bending plate is fixed to the lower surface of the top cover, and the support plate is fixedly disposed on the wall. The support plate is provided with a locking round steel that overlaps with the hook on the bending plate.

[0006] Furthermore, the support plate is welded to the wall.

[0007] Furthermore, the support plate has through holes that mate with the locking round steel.

[0008] Furthermore, both ends of the locking round steel are provided with threads, and the locking round steel is fixedly installed on the support plate by nuts.

[0009] Furthermore, a hook is provided at the bottom end of the bent plate, and the top end of the bent plate is welded to the lower surface of the top cover.

[0010] Furthermore, the curved plate is cut from channel steel, and the number of hooks is two.

[0011] Furthermore, the thread length at the end of the locking round steel is 40 to 60 mm.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model relates to a prefabricated substation roof fixing structure. The fixing points are located on the outside of the wall, eliminating the need for internal installation positions. This significantly improves the utilization of the internal space of the prefabricated substation, reduces its size, and lowers the installation space requirements, which is particularly significant in large cities. Furthermore, the external installation is unaffected by internal structures (such as partitions and reinforcing ribs) or the shape and size of components, allowing for completely uniform distribution in both length and width, resulting in more reliable roof fixing and better enclosure sealing. The fixing points themselves have adjustable tightening distances, requiring less flatness on the upper and lower surfaces of the wall and roof, thus reducing the difficulty of shell processing. In summary, this utility model's prefabricated substation roof fixing structure is ingeniously designed, simple in structure, and practical in function. It effectively solves the problem that existing substation roof fixing methods rely on internal bolt fixation, requiring pre-allocated installation positions and hindering effective use of internal space.

[0021] like Figures 1 to 5As shown, a prefabricated substation top cover fixing structure includes a top cover 2 and fixing points 3. The top cover 2 is located at the top of the wall 1, and the lower surface of the top cover 2 is detachably connected to the outer surface of the wall 1 through several evenly arranged fixing points 3. This utility model's prefabricated substation top cover fixing structure places the fixing points 3 on the outside of the wall 1. External installation is not affected by internal structures (such as partitions, reinforcing ribs) or the shape and volume of components, and can achieve completely uniform distribution in the length and width directions, making the fixing of the top cover 2 more reliable and the sealing of the enclosure better.

[0022] Specifically, the fixing point 3 includes a bent plate 301, a support plate 302, and a locking round steel 303. The top end of the bent plate 301 is fixed to the lower surface of the top cover 2, and a hook is provided at the bottom end of the bent plate 301. The top end of the bent plate 301 is welded to the lower surface of the top cover 2. The bent plate 301 is cut from channel steel, and there are two hooks.

[0023] The support plate 302 is fixedly installed on the wall 1, and the support plate 302 is provided with a locking round steel 303 that overlaps with the hook on the bending plate 301.

[0024] Specifically, the support plate 302 is welded to the wall 1. The support plate 302 has through holes that mate with the locking round steel 303. Both ends of the locking round steel 303 are threaded, with a thread length of 40 to 60 mm, allowing for adjustment during connection. This effectively solves the problem of uneven contact between the top of the wall 1 and the top cover 2 in prefabricated substations (especially long substations). The locking round steel 303 is fixedly installed on the support plate 302 using nuts.

[0025] The fixing point 3 of the prefabricated substation top cover fixing structure of this utility model has an adjustable fastening distance, which reduces the flatness requirements of the upper surface of the wall 1 and the lower surface of the top cover 2, and reduces the difficulty of shell processing.

[0026] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
