Description

Technical Field

[0001] The invention belongs to the technical field of transformer substations, and in particular relates to a spliced ​​transformer substation. Background Art

[0002] Most substations are installed outdoors. Some are transported to the site by vehicles and other equipment after installation and then fixed on the foundation. This method is time-consuming and labor-intensive, and inconvenient to transport. Some are transported to the site by walls and other components for on-site construction and installation. However, this method still has problems such as large wall panels and inconvenient transportation, especially in places with small spaces. In addition, rivets and bolts are often used for on-site splicing. The components are relatively trivial and are only fixed at the connection points of the fixing pins. The fixing points are independent of each other. Therefore, there is a problem of poor installation stability. Summary of the invention

[0003] In view of this, the present invention aims to overcome the deficiencies of the above-mentioned problems in the prior art and proposes a spliced ​​substation.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A spliced ​​substation includes a base, two first side panels spliced ​​together by an H-shaped middle panel are vertically arranged on each of the left and right sides and the rear side of the base, second side panels are vertically arranged at both ends of the front side, and a double-leaf door is connected between the two second side panels, the second side panels and adjacent first side panels and two adjacent first side panels at the corner are spliced ​​together by a corner panel, and a top panel is fixedly connected to the upper sides of the first side panels and the second side panels.

[0006] The corner panels on the rear side are tensioned and fixed together with the two first side panels and the corresponding middle panel on each of the adjacent two sides by means of the first tensioning rope; the corner panels on the front side are tensioned and fixed together with the adjacent second side panels by means of the second tensioning rope, and are tensioned and fixed together with the two first side panels and the middle panel on the adjacent one side by means of the first tensioning rope.

The outer ends of the first side panel and the adjacent second side panel are clamped inside the corner plate and are located on both sides of the isolation strip. Two fixed shafts distributed up and down are fixedly connected to the front end of the isolation strip of each corner plate, and a first tensioning wheel is screwed on each fixed shaft.

[0008] Furthermore, each fixed shaft is threaded with a connecting ring with an internal thread, the first tensioning wheel is interference connected to the circumferential outside of the connecting ring, and an external hexagonal auxiliary ring is fixed to the front end of the first tensioning wheel. The external hexagonal auxiliary ring is sleeved on the fixed shaft and a gap is provided between the inner wall and the fixed shaft.

[0009] Further, the two first side plates connected to the middle plate are respectively clamped in the corresponding card slots on the middle plate, and the middle plate and the corresponding first side plates are fixedly connected together by connecting pins with external threads at the outside of the middle plate corresponding to each corresponding first side plate.

A first fixing hole is formed in the first fixing block. The first fixing column is perpendicular to the first side plate, and a first limiting cap is fixedly connected to the end of the first fixing column. A first pulley is sleeved on the first fixing column. The upper and lower positions of the first fixing blocks on the adjacent two first side plates are arranged in opposite directions, and the upper and lower positions of the first pulleys on the adjacent two first side plates are also arranged in opposite directions.

[0013] On the inner wall of the first side plates on the same side, the initial end of the first tension rope is fixedly connected to the first fixing hole of the first fixing block. The first tension rope is tensioned in a Z-shaped structure, and the other end is wound and fixed on the first tension pulley on the corner plate far from the initial end of the first tension rope on the same side through the second tension pulley on the corresponding Z-shaped track and the first pulley on the adjacent first side plate on the same side.

[0018] Further, connecting blocks are horizontally provided inward at the middle positions of the tops of the first side plate and the second side plate, and one or more threaded holes are formed in each connecting block. The top plate is fixedly connected to the tops of the first side plate and the second side plate through bolts cooperating with the threaded holes in the connecting blocks.

Moreover, the corner plates at the rear side are all tensioned and fixed to the two first side plates on each adjacent side through the first tightening ropes, and the corner plates at the front side are tensioned and fixed to the two first side plates on the adjacent side through the second tightening ropes. After the first side plates, the second side plates, the middle plates and the corner plates are initially spliced together, then the first tightening ropes on the left, right and rear sides are pulled to be tightened, so that the corner plates and the two adjacent first side plates on each side are jointly tensioned through a first tightening rope to enhance the connection stability between them. The second tightening rope on the front side is pulled to be tightened to enhance the connection stability between the second side plate and the adjacent corner plate; before the substation is spliced, the components are more convenient to carry and transfer, and there is no need to fix them through too many bolts. The restraint is greater than that between the adjacent side plates connected by bolts, making the connection between the adjacent first side plates and second side plates on each side firmer.

[0036] The corner plate 7 is an L-shaped structure, and an integrally formed isolation strip 701 is provided at the inner corner of the corner plate 7. The outer ends of the first side plate 2 and the adjacent second side plate 3 are clamped inside the corner plate 7 and located on both sides of the isolation strip 701. Two fixed shafts 702 distributed up and down are fixedly connected to the front end of the isolation strip 701 of each corner plate 7, and each fixed shaft 702 is screwed with a first tensioning wheel 12. In this embodiment, the isolation strip 701 is consistent with the angles on both sides of the corner plate 7, and the angle is consistent with the angle of the outer side of the first side plate 2 and the outer end of the second side plate 3, which is convenient for regular plug-in and also convenient for tensioning and debugging after preliminary assembly.

Of course, the second tensioning wheel 11 can also be screwed onto the connecting pin 10, which is also convenient for individually adjusting the second tensioning wheel 11. In this embodiment, the connecting platform 201 is arranged on the inner side of the first side plate 2 to increase the connection surface between the connecting pin 10 and the first side plate 2, making the connection between the two more firm; the connecting platform 201 is arranged inside the avoidance groove 601, so that while the connecting pin 10 can connect the middle plate 6 and the corresponding first side plate 2, it can also avoid the constraint of the middle plate 6 on the connection part of the connecting pin 10; and the avoidance groove 601 is arranged on the inner side of the middle plate 6 instead of making the whole narrower, in order to increase the connection strength between the two first side plates 2 and the middle plate 6 and avoid the situation that the first side plate 2 tilts inward or even detaches from the middle plate 6 during the installation process.

[0040] A positioning groove 202 is opened at the corresponding position of the outer side of the first side plate 2 and the middle plate 6, and the outer side of the middle plate 6 is clamped in the corresponding positioning groove 202, making the splicing between the first side plate 2 and the middle plate 6 more convenient.

The four peripheral edges of the upper part of the base 1 are abutted against the lower inner side walls of the corresponding first side plate 2 and second side plate 3, further limiting the inner sides of the first side plate 2 and second side plate 3 and enhancing the connection stability of the first side plate 2 and second side plate 3.

[0044] Flanges 103 are horizontally and outwardly provided at the four perimeters of the bottom of the base 1. The lower part of the flanges 103 is embedded in the concrete foundation.

In this embodiment, a reinforcing rib is also connected between each connecting block 20 and the corresponding side panel to enhance the supporting connection strength of the connecting block 20. In addition, in this embodiment, the gap between the top panel 5 and the top of the outer side wall of the first side panel 2 and the second side panel 3 can be sealed by gluing, which can also play a certain fixing role.

[0047] In this embodiment, the first tensioning rope 15 and the second tensioning rope 19 are of a steel wire rope structure, and the tensioning ropes are wound around the first tensioning wheel 12 and the second tensioning wheel 11 for tensioning, which is a conventional technology for tensioning wheels.

[0048] In this embodiment, the width of the first side plate 2 at the rear side can be selected to be greater than the width of the first side plates 2 at the left and right sides according to actual needs.

[0049] The working process of this embodiment is as follows:

[0050] The convex edge 103 at the lower part of the base 1 is embedded in the concrete foundation. The first side plate 2 and the second side plate 3 are correspondingly spliced around the upper part of the base 1, so that the limiting parts 8 of each side plate are pressed against the upper surface of the convex edge 103 at the lower part of the base 1. When splicing, the left and right sides and the rear side are all formed by splicing two first side plates 2 and an intermediate plate 6 into the walls on the left and right sides and the rear side. One end of the two first side plates 2 on each side facing each other is respectively inserted into the clamping grooves 602 on both sides of the H-shaped intermediate plate 6, and then the intermediate plate 6 is preliminarily fixed to the first side plate 2 through the connecting pin 10. And a corner plate 7 is spliced between the two first side plates 2 at the corner, so that the corner plate 7 protects the outside of the first side plate 2, and the isolation strip 701 in the corner plate 7 passes inward from between the two first side plates 2, and then the two first side plates 2 are squeezed towards the isolation strip 701. Similarly, the second side plate 3 at the front side is spliced to the front ends of the corresponding first side plates 2 on the left and right sides through the corner plate 7; the C-shaped beam 9 is installed between the limiting part 8 and the limiting groove 104, so that it presses against the limiting part 8 to ensure that each side plate can be vertically arranged; then the second tensioning wheel 11 is fixedly connected to the connecting pin 10, and the connecting ring fixed with the first tensioning wheel 12 is screwed on the fixed shaft 702, and each first tensioning rope 15 and the second tensioning rope 19 are installed, so that the first tensioning rope 15 is connected in a Z-shaped structure, and the second tensioning rope 19 is connected in a V-shaped structure. Finally, the tension of the first tensioning rope 15 and the second tensioning rope 19 is adjusted. When adjusting the first tensioning rope 15, the connecting pin 10 is screwed outside the intermediate plate 6 to drive the second tensioning wheel 11 to rotate synchronously, realizing the tensioning of the initial end side of the first tensioning rope 15, and then the external hexagonal auxiliary ring 1201 is screwed inside to drive the first tensioning wheel 12 to rotate, realizing the tensioning of the end side of the first tensioning rope 15, and finally the whole first tensioning rope 15 is tightened, thereby strengthening the connection strength between the first side plate 2, the intermediate plate 6 and the corner plate 7 connected thereto, making the connection more stable; similarly, through the rotation of the first tensioning wheel 12 connected to the second tensioning rope 19, the tensioning of the second tensioning rope 19 is realized, strengthening the connection strength between the second side plate 3 and the adjacent first side plate 2 and the corner plate 7, making the connection more stable.

[0051] Then, the C-shaped beam 9 is fixedly connected to the concrete foundation through concrete, making the whole substation more firm; the double-leaf door 4 can be installed between the two second side plates 3. The installation structure of the double-leaf door 4 here is a conventional technical means that can be mastered by those skilled in the art, and the innovation point of this application is not here either, so the specific connection structure of the double-leaf door 4 will not be elaborated here.
