[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: See attached document Figures 1 to 5 A prefabricated box-type substation that is easy to expand includes: The substation enclosure 10 has an open side; the side plate 20 is installed on one side of the substation enclosure 10 by fastening bolts to protect the open side of the substation enclosure 10. The substation enclosure 10 adopts the prefabricated box-type substation shell in the existing technology. Its interior is divided into three main compartments: high voltage compartment, transformer compartment and low voltage compartment. The interior is equipped with high voltage incoming line cabinet, high voltage fuse, surge arrester, live indicator, current / voltage transformer, ring network cabinet or circuit breaker and other equipment and instruments. The expansion component 30 is disposed between the side of the substation enclosure 10 and the side panel 20. The expansion component 30 includes an upper plate 31, a lower plate 32 and two side plates 33. The upper plate 31, the lower plate 32 and the two side plates 33 are used to expand the internal space of the substation enclosure 10 in conjunction with the side panel 20, thereby enhancing the applicability of the prefabricated box-type substation. Mounting component 40 is located inside the substation enclosure 10 and is used to assemble and guide the two side panels 33 to the substation enclosure 10. By first guiding and positioning the two side panels 33 in the expansion assembly 30 through the installation component 40, the ease of subsequent assembly of the upper panel 31, lower panel 32 and side panel 20 can be improved, the steps of positioning multiple sets of panels are reduced, and the efficiency of the box-type substation expansion is improved. Note: After the two side panels 20 are positioned and assembled, their upper panel 31, lower panel 32 and side panels 20 are all assembled with the substation box 10 and the two side panels 20 using fastening bolts.

[0023] See attached document Figure 2 and Figure 5 Several bolt holes 11 are provided on the side of the substation box 10 and on one side of the two side plates 33; several positioning shafts 12 for inserting into the bolt holes 11 on the substation box 10 are fixedly connected to the other side of the two side plates 33. The positioning shaft 12 is used to insert into the bolt hole 11 on the substation box 10, thereby improving the positioning accuracy of the side plate 33 after splicing and overlapping. The side plate 20 is used to be bolted to the bolt holes 11 of the two side plates 33 by fastening bolts or directly bolted to the bolt holes 11 of the substation box 10. The bolt holes 11 allow the side plate 20 to be installed between the two side plates 33 or directly on the side of the substation enclosure 10 using fastening bolts.

[0024] See attached document Figures 2 to 5 The installation component 40 includes a rectangular frame 41 fixed inside the substation enclosure 10. The rectangular frame 41 is used for the installation of assembly units and guide units. The top of the rectangular frame 41 is provided with two assembly units for assembling the side panels 33, which are used to guide and drive the side panels 33 to be installed, improving the convenience of the assembly process. This solves the problem that in the traditional box-type substation, it is necessary to manually align the expansion plates with the installation position of the box-type substation during the assembly process, which is time-consuming, labor-intensive, and difficult to operate. The bottom of the rectangular frame 41 is provided with two guide units for guiding the assembled side panels 33, which further enhances the guidance and load-bearing capacity of the side panels 33 during the assembly process.

[0025] See attached document Figures 3 to 5 The assembly unit includes a threaded sleeve 42 rotatably connected to the top corner of the rectangular frame 41, and a transmission screw 43 is threadedly connected inside the threaded sleeve 42. At least two column-shaped threaded blocks 44 are threadedly connected to the outer surface of the transmission screw 43, and a first L-shaped bracket 45 is rotatably connected to the outer surface of each of the at least two threaded blocks 44. By manually rotating the threaded sleeve 42, the transmission screw 43 can be driven to extend and retract, thereby driving at least two sets of threaded blocks 44 and the first L-shaped bracket 45 to extend and retract, forming a preparatory work for expansion. Moreover, the range of extension and retraction of at least two sets of threaded blocks 44 and the first L-shaped bracket 45 can meet the splicing and assembly work of side panels 33 with different widths. By manually rotating the threaded block 44, the position of its first L-shaped bracket 45 can be adjusted along the axial trajectory of the transmission screw 43, thereby enabling the assembly of the first L-shaped bracket 45 at different positions on the side plate 33 and increasing the assembly range. Note: The assembly unit operation steps are as follows: First, adjust the extension range of the L-shaped bracket by extending and retracting the transmission screw 43 according to the size of the side plate 33 required for expansion; then, fine-tune the position of at least two L-shaped brackets according to the installation position of the side plate 33; finally, suspend the side plate 33 to be assembled on the L-shaped bracket; finally, by extending and retracting the transmission screw 43, make the suspended side plate 33 fit tightly with the side of the substation box 10; finally, lock the upper plate 31, lower plate 32 and side plate 20 with bolts, thus completing the expansion work of the prefabricated box-type substation.

[0026] Several sleeve frames 49 are fixedly connected to the inner surfaces of the two side panels 33; The frame 49 is used to fit onto the first L-shaped bracket 45 for the initial suspension assembly of the side panel 33, so as to improve the convenience of the final assembly of the side panel 33 by driving the mounting end of the mounting component 40. A nut block is fixedly connected to the outer surface of the threaded sleeve 42 and the threaded block 44; Nut blocks are fixedly connected to the outer surfaces of both the threaded sleeve 42 and the threaded block 44, so that workers can use a wrench to rotate the threaded sleeve 42 or the threaded block 44, thereby forming the extension and retraction of the transmission screw 43 or the horizontal displacement of the threaded block 44.

[0027] See attached document Figure 3 and Figure 5 The guide unit includes a guide rod 46 that is slidably connected to the bottom corner of the rectangular frame 41. Two sliding sleeves 47 are slidably connected to the outer surface of one end of the guide rod 46, and a second L-shaped bracket 48 is fixedly connected to the outer surface of the two sliding sleeves 47. The guide rod 46 is used to further enhance the load-bearing capacity of the mounting assembly 40 on the two sets of side panels 33, and the second L-shaped bracket 48 is used to suspend and fix the bottom position of the side panels 33. Note: The outer surface of the guide rod 46 is provided with a groove, and the inside of the sliding sleeve 47 is provided with a protrusion for insertion into the groove, which is used to improve the smoothness and stability of the lateral sliding of the sliding sleeve 47.

[0028] Example 2: The difference from Example 1 is that; See attached document Figure 2 A storage area A is reserved between the rectangular frame 41 and the side of the substation box 10 for storing the first L-shaped bracket 45 and the second L-shaped bracket 48. By reserving a storage area A between the rectangular frame 41 and the side of the substation box 10, the installation end of the installation component 40, namely the first L-shaped bracket 45 and the second L-shaped bracket 48, is hidden when the prefabricated box substation no longer needs to be expanded, so as to prevent it from affecting the installation of the side plate 20.

[0029] Example 3: The difference from Example 1 is that; See attached document Figures 2 to 5 In the assembly unit, the ends of the transmission screw 43 and the guide rod 46 of the guide unit are both provided with guide rail units 50; the guide rail unit 50 includes a guide rail frame 51 fixed inside the substation box 10 and a guide rail seat 52 slidably connected to the guide rail frame 51. The guide rail seat 52 and guide rail bracket 51 are used to improve the guiding performance and load-bearing capacity of the telescopic movement of the transmission screw 43 and guide rod 46, and to improve the stability of the side plate 20 installation and the load-bearing strength of the side plate 20 after installation. The end of the transmission screw 43 is rotatably connected to the inside of the guide rail seat 52, and the inside of the guide rail seat 52 is provided with a locking component for rotating and locking the transmission screw 43. The end of the transmission screw 43 is rotatably connected to the inside of the guide rail seat 52 to improve the smoothness of the lateral movement and the load-bearing capacity of the transmission screw 43. The transmission screw 43 is rotatably connected to the guide rail seat 52, which facilitates manual control of the rotation of the transmission screw 43. This allows at least two first L-shaped hangers 45 to move laterally, thus forming a guiding assembly of the side plate 33. This eliminates the need for manual guiding and splicing, reducing the difficulty of splicing and assembly. Note: The locking component uses existing bolt locking buckles or other methods to lock the transmission screw 43 by rotation. It is used to lock the transmission screw 43 and fix the transmission screw 43 to the guide rail seat 52. In this way, by rotating the threaded sleeve 42, the transmission screw 43 can be driven to perform telescopic movement, forming the assembly of side plates 33 of different widths and sizes. The end of the guide rod 46 is fixed inside the guide rail seat 52; The guide rod 46 is fixedly connected to the guide rail seat 52 to improve the flow, guidance and load-bearing capacity of the lateral movement of the guide rod 46.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
