Technical Field
[0001] This application relates to the field of power distribution equipment technology, and in particular to a standardized prefabricated substation that is easy to assemble and disassemble. Background Technology
[0002] A prefabricated substation, also known as a box-type substation, is a compact set of power distribution equipment that integrates high-voltage power distribution devices, transformers, and low-voltage power distribution devices in a closed or semi-closed metal enclosure according to a certain wiring scheme. Through the steel structure enclosure, it achieves fully enclosed operation with functions such as moisture-proof, rust-proof, dust-proof, and fire-proof. It organically combines functions such as high-voltage power receiving, transformer voltage reduction, and low-voltage power distribution, and is suitable for various scenarios such as urban power grid construction, mines, factories, new energy power generation, and temporary power supply.
[0003] However, in existing prefabricated substations, it has been found that during the transportation and on-site deployment of these substations, the prefabricated units are usually fixed, integrated structures. Due to their large size and heavy weight, they are difficult to assemble on-site, resulting in high transportation costs, stringent requirements for road conditions, and potential delays in project progress. Utility Model Content
[0004] The purpose of this application is to provide a standardized prefabricated substation that is easy to assemble and disassemble, which supports on-site assembly without welding, and whose detachable structure reduces the transport volume of the prefabricated substation, thereby reducing logistics costs and road restrictions, and solving the problems mentioned in the background art.
[0005] This application provides a standardized prefabricated substation that is easy to assemble and disassemble, employing the following technical solution: It includes a base plate, on the upper surface of which are fixedly connected first positioning rods arranged at equal intervals. A top plate is provided above the base plate, and the bottom surface of the top plate is fixedly connected to second positioning rods arranged at equal intervals. A connecting rod is slidably connected to the outer surface of each first positioning rod, and the inner wall of each connecting rod is slidably connected to the outer surface of the corresponding second positioning rod. Multiple fixing bolts arranged at equal intervals are threaded onto each connecting rod. Each connecting rod is detachably connected to the corresponding first and second positioning rods via fixing bolts. Prefabricated substation doors are arranged at equal intervals below the top plate, and hinges arranged at equal intervals are fixedly installed on the outer surface of each door. Each hinge is fixedly installed to the outer surface of the corresponding connecting rod, and two baffles are fixedly installed on the outer surface of each connecting rod.
[0006] By adopting the above technical solution, first positioning rods arranged at equal intervals are installed on the upper surface of the base plate, and a top plate is placed above the base plate. Second positioning rods arranged at equal intervals are installed on the bottom surface of the top plate, with the positions of the first and second positioning rods corresponding to each other. A connecting rod is set on the outer surface of the first positioning rod and connected to the corresponding second positioning rod, so that the connecting rod can be connected to the corresponding first and second positioning rods, thereby realizing the installation of the connecting rod. Equally spaced fixing bolts are installed on the inner walls of the corresponding first and second positioning rods, and the fixing bolts are connected to the corresponding connecting rods, so that the base plate and the top plate can be connected through the first and second positioning rods. The connection of the rods enables the assembly of the frame. The transformer substation door is positioned below the top plate and connected to the door and connecting rods via hinges. This allows the door to be installed on the surface of the connecting rods and supports its opening and closing. A baffle is installed on the outer surface of the connecting rods to prevent the door from closing excessively. When the device needs to be transported, the various components are disassembled. Upon arrival at the site, the connecting rods are connected to the corresponding first and second positioning rods using fixing bolts. Then, the door and hinges are installed sequentially. This allows the device to support on-site assembly without welding, and the detachable structure reduces the transport volume of the transformer substation, lowering logistics costs and reducing road restrictions.
[0007] Preferably, an electric push rod is fixedly connected to the inner wall of the top plate, and the output end of the electric push rod is fixedly installed with the transformer substation top cover.
[0008] By adopting the above technical solution, electric push rods arranged at equal intervals are installed on the inner wall of the top plate to realize the installation of electric push rods. The transformer top cover is installed at the output end of the electric push rods, so that the electric push rods can drive the transformer top cover to rise and fall. This allows the transformer top cover to be lowered after installation. When the whole transformer is transported, the overall height can be reduced, reducing space occupation. On-site, the original shape can be restored by extending the electric push rods. Furthermore, when the transformer top cover is lowered, the inner side wall of the transformer top cover can limit the corresponding transformer door to prevent the transformer door from being accidentally opened during transportation.
[0009] Preferably, the inner top wall of the transformer substation top cover is fixedly connected with guide rods arranged at equal intervals, and the outer surface of each guide rod is slidably connected to the inner wall of the top plate.
[0010] By adopting the above technical solution, guide rods arranged at equal intervals are installed on the inner top wall of the transformer substation cover and set as fixed connections. The outer surface of the guide rods is connected to the inner wall of the top plate and set as a sliding connection. When the electric push rod drives the transformer substation cover to rise and fall, the connection between the guide rods and the top plate can limit the movement and ensure the stable raising and lowering of the transformer substation cover.
[0011] Preferably, the inner wall of the base plate is fixedly connected with fixing blocks arranged at equal intervals, and each fixing block has a limiting groove on its bottom surface.
[0012] By adopting the above technical solution, a fixing block is set on the inner wall of the base plate to form a fixed connection, thereby realizing the installation of the fixing block. A limiting groove is opened on the bottom surface of the fixing block to realize the positioning of the limiting groove.
[0013] Preferably, each of the limiting grooves has a slider slidably connected to its inner wall, and each slider has a support foot fixedly connected to its bottom end.
[0014] By adopting the above technical solution, the slider is set on the inner wall of the limiting groove, and the slider and the limiting groove are set as a sliding connection, so that the limiting groove can limit the slider. The support foot is installed at the bottom of the slider and set as a fixed connection, so that the support foot and the slider can support the main body of the transformer.
[0015] Preferably, the inner wall of each of the fixed blocks is rotatably connected to a first bevel gear, and the outer surface of each first bevel gear is meshed with a second bevel gear.
[0016] By adopting the above technical solution, the first bevel gear is installed on the inner wall of the corresponding fixed block and configured as a rotatable connection to limit the movement of the first bevel gear. The second bevel gear is set on the side of the first bevel gear and meshed with the first bevel gear, so that when the operator rotates the first bevel gear, the second bevel gear can rotate.
[0017] Preferably, each of the second bevel gears has a threaded rod fixedly connected to its inner wall, and the top end of each threaded rod is rotatably connected to the inner top wall of the corresponding limiting groove.
[0018] By adopting the above technical solution, the threaded rod is installed on the inner wall of the corresponding second bevel gear, and the top end of the threaded rod is connected to the inner top wall of the corresponding limiting groove, which is set as a rotating connection, so that when the operator rotates the first bevel gear, the second bevel gear and the threaded rod can rotate synchronously.
[0019] Preferably, the outer surface of each threaded rod is threadedly connected to the inner wall of the corresponding slider.
[0020] By adopting the above technical solution, the threaded rod is connected to the corresponding slider, so that when the threaded rod rotates, the slider can rise and fall on the inner wall of the limiting groove, thereby allowing the support legs to rise and fall. This allows the device to easily adjust the height of each support leg, so that when the transformer substation is placed on the ground, it can adapt to terrains with different flatness.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This standardized prefabricated substation, which is easy to assemble and disassemble, is equipped with components such as a first positioning rod, a second positioning rod, a connecting rod, and fixing bolts. When the components are transported to the site, they are connected to the corresponding first and second positioning rods via the connecting rods. Then, by installing the fixing bolts, the corresponding connecting rods can be connected to the corresponding first and second positioning rods, completing the frame assembly. Hinges are installed to allow the substation door to be installed in place, thus completing the assembly of the substation. This device supports on-site assembly without welding, and the detachable structure reduces the transport volume of the substation, lowering logistics costs and road restrictions. The operator rotates the corresponding first bevel gear, which causes the corresponding second bevel gear to rotate. The second bevel gear is fixedly connected to the threaded rod, allowing it to rotate together with the corresponding threaded rod. The threaded connection between the threaded rod and the slider allows the slider to rise and fall along the limit groove when the threaded rod rotates, achieving the lifting effect of the support legs. This allows the substation to adapt to terrains with different flatness when placed on the ground, improving the applicability of the device. Attached Figure Description

Detailed Implementation
[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0025] Example 1: A standardized prefabricated substation that is easy to assemble and disassemble; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The system includes a base plate 1, with equal-distance first positioning rods 2 fixedly connected to the upper surface of the base plate 1. A top plate 3 is located above the base plate 1. The equal-distance first positioning rods 2 are installed on the upper surface of the base plate 1, and the top plate 3 is positioned above the base plate 1. Equal-distance second positioning rods 4 are fixedly connected to the bottom surface of the top plate 3. A connecting rod 5 is slidably connected to the outer surface of each first positioning rod 2. The inner wall of each connecting rod 5 is slidably connected to the outer surface of the corresponding second positioning rod 4. Equal-distance second positioning rods 4 are installed on the bottom surface of the top plate 3, with the positions of the first positioning rods 2 and second positioning rods 4 corresponding. Connecting rods 5 are positioned on the outer surface of the first positioning rods 2, and the connecting rods 5 are connected to the outer surface of the first positioning rods 2. Rod 5 is connected to the corresponding second positioning rod 4, so that connecting rod 5 can be connected to the corresponding first positioning rod 2 and second positioning rod 4, thereby realizing the installation of connecting rod 5. Each connecting rod 5 is threaded with multiple equally spaced fixing bolts 6. Each connecting rod 5 is detachably connected to the corresponding first positioning rod 2 and second positioning rod 4 through fixing bolts 6. Equally spaced fixing bolts 6 are installed on the inner walls of the corresponding first positioning rod 2 and second positioning rod 4, and the fixing bolts 6 are connected to the corresponding connecting rod 5, so that the bottom plate 1 and the top plate 3 can be assembled through the connection of the first positioning rod 2, the second positioning rod 4 and the connecting rod 5.
[0026] Please see Figure 1 , Figure 2 and Figure 3 Below the top plate 3, there are equally spaced transformer substation doors 7. Each transformer substation door 7 has equally spaced hinges 8 fixedly installed on its outer surface. Each hinge 8 is fixedly installed on the outer surface of a corresponding connecting rod 5. The transformer substation doors 7 are positioned below the top plate 3 and connected to the connecting rods 5 via the hinges 8, allowing the corresponding transformer substation doors 7 to be installed on the surface of the connecting rods 5 and supporting the opening and closing of the transformer substation doors 7. Two baffles 9 are fixedly installed on the outer surface of each connecting rod 5, which can block the transformer substation doors 7 and prevent them from closing excessively. When the device needs to be transported, the various components are disassembled. After arriving at the site, the connecting rods 5 are connected to the corresponding first positioning rods 2 and second positioning rods 4 via fixing bolts 6. Then, the transformer substation doors 7 and hinges 8 are installed in sequence. This allows the device to support on-site assembly without welding, and the detachable structure reduces the transport volume of the transformer substation, lowering logistics costs and road restrictions.
[0027] Example 2: A standardized prefabricated substation that is easy to assemble and disassemble; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4An electric push rod 10 is fixedly connected to the inner wall of the top plate 3. A transformer substation top cover 11 is fixedly installed at the output end of the electric push rod 10. Electric push rods 10 are installed at equal intervals on the inner wall of the top plate 3 to facilitate their installation. The transformer substation top cover 11 is installed at the output end of the electric push rod 10, allowing the electric push rod 10 to drive the transformer substation top cover 11 to rise and fall. This allows the transformer substation top cover 11 to be lowered after installation. When the entire transformer substation is transported, its overall height can be reduced, minimizing space occupation. On-site, the original shape can be restored by extending the electric push rod 10. Furthermore, when the transformer substation top cover 11 lowers, its... The inner wall can limit the corresponding transformer substation door 7 to prevent accidental opening of the transformer substation door 7 during transportation. The inner top wall of the transformer substation top cover 11 is fixedly connected with guide rods 12 arranged at equal intervals. The outer surface of each guide rod 12 is slidably connected to the inner wall of the top plate 3. The guide rods 12 arranged at equal intervals are installed on the inner top wall of the transformer substation top cover 11 and are set as fixed connections. The outer surface of the guide rods 12 is connected to the inner wall of the top plate 3 and is set as a sliding connection. When the electric push rod 10 drives the transformer substation top cover 11 to rise and fall, it can be limited by the connection between the guide rods 12 and the top plate 3 to ensure the stable rise and fall of the transformer substation top cover 11.
[0028] Please see Figure 2 , Figure 3 and Figure 5 The inner wall of the base plate 1 is fixedly connected with equidistantly arranged fixing blocks 13. Each fixing block 13 has a limiting groove 14 on its bottom surface. The fixing blocks 13 are fixedly connected to the inner wall of the base plate 1 to achieve installation of the fixing blocks 13. The limiting groove 14 is opened on the bottom surface of the fixing blocks 13 to achieve positioning of the limiting groove 14. Each limiting groove 14 has a slider 15 slidably connected to its inner wall. Each slider 15 has a support foot 16 fixedly connected to its bottom end. The slider 15 is set on the inner wall of the limiting groove 14, and the slider 15 and the limiting groove 14 are slidably connected so that the limiting groove 14 can limit the slider 15. The support foot 16 is installed on the bottom end of the slider 15 to achieve a fixed connection so that the support foot 16 and the slider 15 can support the main body of the transformer.
[0029] Please see Figure 2 , Figure 3 and Figure 5Each fixed block 13 has a first bevel gear 17 rotatably connected to its inner wall, and a second bevel gear 18 meshes with the outer surface of each first bevel gear 17. The first bevel gear 17 is mounted on the inner wall of the corresponding fixed block 13, forming a rotatable connection to limit its movement. The second bevel gear 18 is positioned on the side of the first bevel gear 17, and the first bevel gear 17 meshes with the second bevel gear 18, allowing the second bevel gear 18 to rotate when the operator rotates the first bevel gear 17. Each second bevel gear 18 has a threaded rod 19 fixedly connected to its inner wall, and the top end of each threaded rod 19 is rotatably connected to the inner top wall of the corresponding limiting groove 14. 9 is installed on the inner wall of the corresponding second bevel gear 18, and the top end of the threaded rod 19 is connected to the inner top wall of the corresponding limiting groove 14, which is set as a rotatable connection. When the operator rotates the first bevel gear 17, it can drive the second bevel gear 18 and the threaded rod 19 to rotate synchronously. The outer surface of each threaded rod 19 is threadedly connected to the inner wall of the corresponding slider 15. Connecting the threaded rod 19 to the corresponding slider 15 allows the slider 15 to rise and fall on the inner wall of the limiting groove 14 when the threaded rod 19 rotates, thereby allowing the support leg 16 to rise and fall. This allows the device to easily adjust the height of each support leg 16, so that when the transformer box is placed on the ground, it can adapt to terrains with different flatness.
[0030] The implementation principle of this application embodiment is as follows: First, the various components are transported to the installation site by a transport vehicle. Then, the base plate 1 is placed on the ground where it needs to be installed. At this time, the operator rotates the corresponding first bevel gear 17 so that the corresponding second bevel gear 18 can rotate. Through the fixation of the second bevel gear 18 and the threaded rod 19, the threaded rod 19 can rotate. Through the connection of the threaded rod 19 and the slider 15, the slider 15 can rise and fall along the limiting groove 14, thereby making the height of the support leg 16 adjustable. This allows the device to adapt to terrains with different flatness when assembling the transformer substation, improving the applicability of the device. Then, the connecting rod 5 is connected to the corresponding first positioning rod 2 and second positioning rod 4. After assembly, the first positioning rod can be fixed by the installation fixing bolt 6. 2. The second positioning rod 4 and the connecting rod 5 are fixed to achieve the assembly and fixation of the frame. Then, the transformer substation door 7 is installed in place by the hinge 8. At this time, the overall assembly of the transformer substation is completed, which enables the device to support on-site assembly without welding. The detachable structure reduces the transportation volume of the transformer substation, thereby reducing logistics costs and road restrictions. When the assembled transformer substation needs to be transferred or transported, the electric push rod 10 is activated to drive the transformer substation top cover 11 to descend, thereby reducing the overall height of the transformer substation during transportation and reducing space occupation. After arriving at the transportation location, the original shape can be restored by extending the electric push rod 10. When the transformer substation top cover 11 descends, the inner side wall of the transformer substation top cover 11 can limit the transformer substation door 7 to prevent the transformer substation door 7 from being accidentally opened during transportation.
