[0002] A box-type substation is also called a prefabricated substation or a prefabricated transformer substation. It is a high-voltage switchgear, a distribution transformer and a low-voltage distribution device, which are arranged in a factory prefabricated indoor and outdoor compact distribution equipment according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulating, fully enclosed and movable steel structure box, which is especially suitable for urban network construction and transformation and is a brand-new substation that has emerged after the civil substation. The box-type substation is suitable for mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution room and substation and becomes a new type of complete set of power transformation and distribution devices.

The right side surface of the bearing is fixedly installed with a moving plate, and the upper and lower side surfaces of the moving plate are respectively in movable contact with the inner wall of the upper side of the rectangular box and the upper surface of the buckle plate body.

[0009] Furthermore, the limiting mechanism includes a limiting rod and a limiting hole. The limiting rod is fixedly installed on the side surface of the moving plate facing the buckle edge. Limiting holes are formed in the adjacent buckle edges on the left and right corresponding to the limiting rod.

[0022] In this embodiment, the galvanized steel plate 101 has greater structural strength and a more beautiful appearance.

[0023] Specifically, the gusset plate body 1 is evenly provided with mounting holes 6 .

[0024] In this embodiment, the mounting hole 6 is used for mounting and fixing the gusset plate body 1 .

[0025] Specifically, the adjusting mechanism 4 includes a threaded hole 401, a bolt rod 402, a bearing 403 and a moving plate 404. A threaded hole 401 is formed in the middle position of the side wall of the rectangular box 3. The bolt rod 402 is threadedly installed in the threaded hole 401. A bearing 403 is installed on the side of the bolt rod 402 facing the buckle edge 2. The right side of the bearing 403 is fixedly installed with a moving plate 404, and the upper and lower sides of the moving plate 404 are respectively in movable contact with the inner wall of the upper side of the rectangular box 3 and the upper surface of the buckle main body 1.

[0026] In this embodiment, the bolt rod 402 moves spirally in the threaded hole 401, so that the bolt rod 402 drives the moving plate 404 to move towards the buckle edge 2 through the bearing 403, achieving the effect of driving the limiting mechanism 5 to move towards the buckle edge 2 by the moving plate 404.

[0027] Specifically, the limiting mechanism 5 includes a limiting rod 501 and a limiting hole 502.

Then, through the spiral movement of the bolt rod 402 in the threaded hole 401 in the left and right adjustment mechanism 4, the bolt rod 402 drives the moving plate 404 to move towards the buckle edge 2 through the bearing 403, achieving the effect that the moving plate 404 drives the limiting mechanism 5 to move towards the buckle edge 2, so that the limiting rod 501 in the left and right limiting mechanisms 5 is inserted into the limiting hole 502, making the left and right buckle edges 2 that are in contact with each other aligned left and right and front and back, and not moving in the front and back directions. At the same time, the rectangular box 3 is fixedly connected to the left and right buckle edges 2 that are in contact with each other, achieving the effect of fixedly connecting the left and right buckle main bodies 1. On the contrary, it is also convenient to disassemble the buckle main bodies 1, greatly improving the disassembly and assembly efficiency, and having a large connection strength and higher docking accuracy.
