[0002] A substation is an electrical facility within a power system that transforms voltage, receives and distributes electrical energy, controls the flow of power, and adjusts voltage. There are many different types of substations. Prefabricated substations, among them, are built by assembling individual modules in prefabricated compartments, each assembled according to its function. These modules are then transported to the site and assembled. Prefabricated substations are widely used due to their compact layout and rapid construction. Currently, the scale of prefabricated substations is steadily increasing, and the dimensions of single-module prefabricated substations are increasing. However, due to the length and width limitations of road transport requirements, the layout dimensions of the power distribution cabinets installed within the compartments often exceed the maximum transport dimensions of the compartments. This necessitates that the larger modular compartments be segmented. The power distribution cabinets and other electrical equipment are then installed in the subdivided compartments at the factory and assembled into a single compartment upon transport to the site.

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A substation prefabricated cabin auxiliary assembly device, see Figures 1 to 4 , including a bottom plate 1 and a cabin body 2, an adjustment slot 11 is opened in the middle of the surface of the bottom plate 1, a bidirectional screw rod 13 is rotatably connected between the two sides of the inner cavity of the adjustment slot 11, and two adjustment blocks 12 are slidably connected on both sides of the inner cavity of the adjustment slot 11, and a mounting plate 14 is installed on the two adjustment blocks 12 on the same side. Two connecting plates 4 are arranged between the two mounting plates 14 on the same side, and rectangular holes 41 are opened on the two connecting plates 4 on the same side; a fixing plate 21 is fixedly connected to the bottom of the cabin body 2, Both sides of the surface of the fixing plate 21 are penetrated by fixing bolts 22, and the fixing bolts 22 are adapted to the rectangular holes 41. When working, the solid bottom plate 1 is overlapped on the mounting plate 14, and then the fixing bolts 22 are passed through the rectangular holes 41 to fix the cabin 2. Then, by rotating the bidirectional screw rod 13 and cooperating with the adjustment block 12 to guide and move in the adjustment groove 11, the two cabins 2 are driven to approach each other, so that the cabins 2 can be spliced ​​more conveniently, so that the cabins 2 can be spliced ​​quickly, further improving the efficiency of splicing the cabins 2.

[0022] For details, see Figure 2 One end of the bidirectional screw rod 13 rotates through the adjustment slot 11 and is placed on the outside of the base plate 1. A driven gear 52 is installed on the bidirectional screw rod 13 on the outside of the base plate 1. A servo motor 5 is installed at one end of the base plate 1 close to the driven gear 52. A driving gear 51 is installed at the driving end of the servo motor 5. The driving gear 51 is engaged with the driven gear 52. When the cabin body 2 is spliced, the servo motor 5 is started to drive the driving gear 51 to rotate, thereby cooperating with the driven gear 52 to drive the bidirectional screw rod 13 to rotate, and then the cabin body 2 can be automatically moved and spliced.

[0023] For further information, see Figure 3 and Figure 4, a slide groove 43 is provided at the opposite end of the two mounting plates 14 on the same side, and two sliders 42 are slidably connected in the two slide grooves 43. The two ends of the connecting plate 4 are respectively connected to the two sliders 42, and the sliders 42 are guided to move in the slide grooves 43, so that the position of the connecting plate 4 between the two mounting plates 14 can be adjusted, thereby facilitating the adjustment of the rectangular hole 41 on the connecting plate 4 to correspond to the fixing bolts 22 on the fixing plates 21 of different sizes, thereby making it more convenient for the fixing bolts 22 to pass through the rectangular hole 41.

[0024] It is worth noting that, see Figure 3 A guide wheel 6 is installed at the bottom of the slider 42, and the guide wheel 6 contacts the bottom end of the inner cavity of the slide groove 43. The connection height between the guide wheel 6 and the slider 42 is adapted to the inner cavity depth of the slide groove 43. By setting the guide wheel 6, the friction force between the slider 42 and the bottom of the slide groove 43 is reduced, thereby facilitating the movement of the cabin body 2 toward each other for splicing.

[0025] It is worth noting that see Figure 1 A protective cover 3 is provided at one end of the base plate 1 close to the servo motor 5. The protective cover 3 is hinged to the base plate 1 through a hinge. The protective cover 3 is convenient for shielding the servo motor 5, thereby effectively protecting the servo motor 5, the driving gear 51 and the driven gear 52, and further extending the service life of the servo motor 5, the driving gear 51 and the driven gear 52.
