Description

Technical Field

[0001] This utility model belongs to the field of prefabricated substation technology, and specifically relates to an expandable prefabricated substation foundation connection frame. Background Technology

[0002] A prefabricated substation, or simply "prefabricated substation," is a compact substation that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment within an enclosed enclosure. Its design follows modular and standardized principles, featuring small footprint, rapid installation, and strong environmental adaptability, and it is widely used in the terminal distribution stages of power systems.

[0003] During the assembly of a prefabricated substation, the internal support structure is a core component ensuring the stable installation of electrical equipment. Traditional prefabricated substations typically use metal support rods to provide rigid fixation for electrical equipment such as circuit breakers and instrument transformers. A typical structure includes the support rod body and a matching mounting frame. Both ends of the support rod are directly bolted to pre-drilled circular holes on the side wall of the frame. The bolts at both ends must be tightened separately. Multiple circular holes are evenly spaced along the length of the frame side wall. By selecting different hole positions, the lateral position of the support rod can be adjusted or new support rods can be added. Each support rod must be individually aligned with the bolt holes at both ends, and the bolts on both sides must be tightened one by one. This process is particularly time-consuming when working inside a narrow enclosure due to limited operating space. Utility Model Content

[0004] To address the issue that each support rod needs to be individually aligned with the bolt holes at both ends, and the bolts on both sides need to be tightened one by one, especially when construction is carried out in a narrow enclosure where limited operating space leads to increased time consumption, this utility model proposes an expandable transformer substation foundation connection frame to overcome the aforementioned technical problems existing in the relevant technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an expandable prefabricated substation foundation connection frame, comprising a housing, a support assembly fixedly installed inside the housing, a sliding frame provided on the outer surface of the support assembly, a rotating assembly and a displacement assembly provided inside the sliding frame, and a telescopic assembly provided on the outer surface of the sliding frame. The rotating assembly is used to drive the displacement assembly to move. There are two sets of displacement assemblies, located at opposite ends of the rotating assembly. Both the displacement assembly and the telescopic assembly are plugged into the support assembly. The displacement assembly supports the sliding frame, and the telescopic assembly guides the movement of the sliding frame.

[0007] Furthermore, the support assembly includes a base plate, the outer surface of which is threaded with bolts, and the base plate is fixedly installed inside the housing by bolts. A square column is fixedly connected to the top of the base plate, and the outer surface of the square column is respectively provided with grooves and round holes, and there are multiple sets of round holes.

[0008] Furthermore, the rotating assembly includes a rotating shaft, with a circular plate fixedly connected to the end of the rotating shaft. Both the rotating shaft and the circular plate are rotatably connected to the sliding frame. A handle is fixedly connected to the outer surface of the rotating shaft, and a hexagonal block is fixedly connected to the outer surface of the handle.

[0009] Furthermore, the displacement assembly includes a screw cylinder, which is fixedly connected to a circular plate. A screw rod is threadedly connected to the inside of the screw cylinder, and a sliding plate is fixedly connected to the end of the screw rod. A rod is fixedly connected to the outer surface of the sliding plate, and the sliding plate is slidably connected inside the sliding frame.

[0010] Furthermore, the telescopic assembly includes a fixed base, a limiting plate is fixedly connected to the outer surface of the fixed base, a spring is fixedly connected to the outer surface of the limiting plate, a telescopic base is fixedly connected to the end of the spring, the telescopic base is slidably connected to the slide groove, and a push plate is fixedly connected to the outer surface of the telescopic base.

[0011] Furthermore, the outer surface of the sliding frame is provided with several connection holes.

[0012] Furthermore, a heat dissipation box is fixedly installed on the outer surface of the box, and heat dissipation grooves are formed on the outer surface of the heat dissipation box, and the heat dissipation box is in communication with the box.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects a rotating component and a displacement component. The two displacement components are located at the two ends of the rotating component. When the rotating component rotates, it drives the two displacement components to move simultaneously, so that the two displacement components extend out of the sliding frame and are inserted into the support component. At this time, the displacement components can support the sliding frame. When a new sliding frame is installed on the surface of the support component, it is only necessary to rotate the rotating component to quickly push out the two displacement components to limit and fix the sliding frame, which helps to reduce the working time.

[0015] 2. This utility model connects the sliding frame and the fixed seat, pushing the telescopic seat to slide closer to the sliding frame. The telescopic seat compresses the spring, and at this time the overall length of the sliding frame and the telescopic seat is shortened. The sliding frame and the telescopic seat can be placed between two sets of square columns. When the telescopic seat is released, the spring pushes the telescopic seat to reset so that it enters the slide groove. The telescopic seat and the slide groove cooperate with each other to prevent lateral displacement when adjusting the height of the sliding frame.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is an expandable prefabricated substation foundation connection frame, including a housing 1. A support component 2 is fixedly installed inside the housing 1. A sliding frame 3 is provided on the outer surface of the support component 2. A rotating component 4 and a displacement component 5 are provided inside the sliding frame 3. A telescopic component 6 is provided on the outer surface of the sliding frame 3. The rotating component 4 is used to drive the displacement component 5 to move. There are two sets of displacement components 5, which are located at the two ends of the rotating component 4. Both the displacement component 5 and the telescopic component 6 are inserted into the support component 2. The displacement component 5 is used to support the sliding frame 3, and the telescopic component 6 is used to guide the movement of the sliding frame 3.

[0029] Push the telescopic component 6 to retract it and bring it close to the sliding frame 3. After placing the sliding frame 3 on the support component 2, release the telescopic component 6. The telescopic component 6 will reset and plug into the support component 2. At this time, the sliding frame 3 can slide up and down under the guidance of the telescopic component 6, thereby adjusting the installation position of the sliding frame 3. After adjusting the sliding frame 3 to a suitable height, rotate the rotating component 4 inside the sliding frame 3. The rotating component 4 drives the displacement component 5 to move so that it extends and plugs into the support component 2. At this time, the displacement component 5 can limit and fix the sliding frame 3. At this time, the electrical equipment can be installed on the sliding frame 3 inside the housing 1. When performing extended installation, only the rotating component 4 needs to be rotated to drive the two sets of displacement components 5 to move simultaneously to plug into the support component 2, which is more convenient to use and reduces working time.

[0030] This invention connects the rotating component 4 and the displacement component 5. The two displacement components 5 are located at the two ends of the rotating component 4. When the rotating component 4 rotates, it drives the two displacement components 5 to move simultaneously, so that the two displacement components 5 extend out of the sliding frame 3 and are inserted into the support component 2. At this time, the displacement components 5 can support the sliding frame 3. When a new sliding frame 3 is installed on the surface of the support component 2, it is only necessary to rotate the rotating component 4 to quickly push out the two displacement components 5 to limit and fix the sliding frame 3, which helps to reduce the working time.

[0031] In one embodiment, the support component 2 includes a base plate 201, the outer surface of which is threaded with bolts 202. The base plate 201 is fixedly installed inside the housing 1 by bolts 202. A square column 203 is fixedly connected to the top of the base plate 201. The outer surface of the square column 203 is provided with a sliding groove 204 and a round hole 205, and there are multiple sets of round holes 205.

[0032] After pushing the base plate 201 and the square column 203 into the box 1, install the bolt 202 on the base plate 201, rotate the bolt 202 so that it passes through the base plate 201 and is threadedly connected to the box 1, and the base plate 201 and the square column 203 can be fixed in the box 1.

[0033] In one embodiment, the rotating component 4 includes a rotating shaft 401, with a circular plate 402 fixedly connected to the end of the rotating shaft 401. Both the rotating shaft 401 and the circular plate 402 are rotatably connected to the sliding frame 3. A handle 403 is fixedly connected to the outer surface of the rotating shaft 401, and a hexagonal block 404 is fixedly connected to the outer surface of the handle 403.

[0034] The operator can directly hold the handle 403 or use a wrench to push the hexagonal block 404 to rotate. The handle 403 and the hexagonal block 404 drive the rotating shaft 401 and the circular plate 402 to rotate. The circular plate 402 limits the rotating shaft 401 to prevent unnecessary axial movement of the rotating shaft 401.

[0035] In one embodiment, the displacement component 5 includes a screw cylinder 501, which is fixedly connected to a circular plate 402. A screw rod 502 is threadedly connected to the inside of the screw cylinder 501. A sliding plate 503 is fixedly connected to the end of the screw rod 502. A plug rod 504 is fixedly connected to the outer surface of the sliding plate 503. The sliding plate 503 is slidably connected inside the sliding frame 3.

[0036] The rotating shaft 401 drives the circular plate 402 and the screw barrel 501 to rotate. The rotation trend of the screw 502 inside the screw barrel 501 is blocked by the sliding plate 503 and the sliding frame 3. At this time, the screw barrel 501 can drive the screw 502 to slide the sliding plate 503. The sliding plate 503 drives the insertion rod 504 to slide. When the insertion rod 504 extends out from the sliding frame 3 and is inserted into the circular hole 205, the sliding frame 3 can be limited and fixed.

[0037] In one embodiment, the telescopic component 6 includes a fixed base 601, a limiting plate 602 fixedly connected to the outer surface of the fixed base 601, a spring 603 fixedly connected to the outer surface of the limiting plate 602, a telescopic base 604 fixedly connected to the end of the spring 603, the telescopic base 604 being slidably connected to the slide groove 204, and a push plate 605 fixedly connected to the outer surface of the telescopic base 604.

[0038] When installing a new sliding frame 3 on the square column 203, first push the push plate 605 to move the telescopic seat 604 closer to the sliding frame 3. The telescopic seat 604 compresses the spring 603. After the telescopic seat 604 retracts, it places the sliding frame 3 between the two sets of square columns 203. Release the push plate 605, and the spring 603 pushes the telescopic seat 604 to reset, so that the telescopic seat 604 enters the slide groove 204. The telescopic seat 604 and the slide groove 204 cooperate to guide the sliding frame 3, so that the sliding frame 3 can slide on the surface of the square column 203, thereby adjusting the installation position of the newly extended sliding frame 3.

[0039] In one embodiment, the outer surface of the sliding frame 3 is provided with a plurality of connection holes 7.

[0040] Several connection holes 7 are opened on the surface of the sliding frame 3 for connecting and fixing various electrical equipment.

[0041] In one embodiment, for the aforementioned housing 1, a heat dissipation box 8 is fixedly installed on the outer surface of the housing 1, and a heat dissipation groove 9 is formed on the outer surface of the heat dissipation box 8, and the heat dissipation box 8 is in communication with the housing 1.

[0042] The heat dissipation box 8 is equipped with a fan, which dissipates heat from the box 1 and the heat dissipation box 8 through the heat dissipation slot 9, thereby preventing the electrical equipment in the box 1 from overheating.

[0043] Through the above technical solution, 1. By connecting the rotating component 4 and the displacement component 5, the two sets of displacement components 5 are located at both ends of the rotating component 4. When the rotating component 4 rotates, it drives the two sets of displacement components 5 to move simultaneously, causing the two sets of displacement components 5 to extend from the sliding frame 3 and insert into the support component 2. At this time, the displacement components 5 can support the sliding frame 3. When a new sliding frame 3 is installed on the surface of the support component 2, it is only necessary to rotate the rotating component 4 to quickly push out the two sets of displacement components 5 to limit and fix the sliding frame 3, which is beneficial to reduce 1. Reduced working time; 2. By connecting the sliding frame 3 and the fixed seat 601, the telescopic seat 604 is pushed to slide closer to the sliding frame 3. The telescopic seat 604 compresses the spring 603. At this time, the overall length of the sliding frame 3 and the telescopic seat 604 is shortened, and the sliding frame 3 and the telescopic seat 604 can be placed between the two sets of square columns 203. When the telescopic seat 604 is released, the spring 603 pushes the telescopic seat 604 to reset so that it enters the slide groove 204. The telescopic seat 604 and the slide groove 204 cooperate with each other to prevent lateral displacement when adjusting the height of the sliding frame 3.
