Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically to a prefabricated substation with an adaptive disassembly and assembly structure. Background Technology

[0002] Prefabricated substations are widely used in urban power distribution, industrial and mining enterprises, and certain special locations (such as highways, airports, docks, petrochemical plants, etc.). Compared with traditional substations, prefabricated substations have significant advantages in terms of maintenance and management, temporary availability, and convenience. Existing technology discloses a prefabricated substation that can be quickly assembled using its base plate, fixed columns, enclosure, and top plate. Each structure is prefabricated on-site and can be immediately installed upon arrival at the construction site, shortening the construction period and significantly reducing labor costs.

[0003] A search revealed that patent application number CN202420929893.7 discloses a prefabricated substation. Although the adjustment components can simplify the operation process of the prefabricated frame to a certain extent, in actual installation scenarios, the adjustment components are only for the prefabricated frame and have limited effect on improving the stability of the connection between the overall substation and the foundation. Moreover, when facing complex outdoor environments, it is difficult to provide reliable pull-out and shear resistance, which can easily lead to the risk of the overall structure loosening or even tipping over. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated substation with an adaptive disassembly and assembly structure, thus solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A prefabricated substation with an adaptive disassembly and assembly structure includes a prefabricated transformer box, which is mounted on a base by a pressure strip;

[0007] The base has side plates on both sides, and the two ends of the side plates have a first inclined groove and a second inclined groove. The lower part of the prefabricated transformer box has a limiting post. The prefabricated transformer box is guided and limited on the base by the limiting post and the second inclined groove of the side plate, as well as the prefabricated transformer box and the first inclined groove. The two ends of the pressure strip have wedges, and the wedges are located in the gap between the first inclined groove at both ends of the side plate and the prefabricated transformer box.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the pressure strip is provided with a slot, and the position and size of the slot are adapted to the position and size of the limiting post. The pressure strip limits the limiting post of the prefabricated transformer box through the slot.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The precise fit between the slot and the limiting post forms a rigid limiting structure in the vertical direction, preventing the prefabricated transformer box from jumping up and down during equipment operation or transportation. At the same time, it provides a stable force benchmark for the lateral wedging of the pressure strip, avoiding the accumulation of installation errors caused by vertical displacement.

[0012] Furthermore, a limiting seat is provided at the bottom end of the base, and the base is installed on the concrete base through the limiting seat.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The embedded connection between the limiting seat and the concrete seat forms a composite force system that resists pull-out and shear, significantly enhancing the connection strength between the base and the foundation, and enabling it to withstand larger loads. At the same time, the geometry of the limiting seat can assist the base in quickly aligning horizontally, reducing the leveling process during installation and improving construction efficiency.

[0015] Furthermore, the base has fixing holes, and the base is connected and fixed to the pressure strip through the fixing holes and bolts.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The fit between the fixing holes and bolts provides a reliable mechanical connection fulcrum for the pressure strip, enabling the pressure strip to convert the vertical tension of the bolts into lateral compressive force during the wedging process; the standardized fixing hole layout facilitates quick positioning and installation of the pressure strip, is compatible with bolts and fasteners of different specifications, and improves component interchangeability and maintenance convenience.

[0018] Furthermore, the side panel facing the prefabricated transformer box has an elastic buffer layer, which is used to buffer the impact force during the installation of the prefabricated transformer box.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The elastic buffer layer can absorb the kinetic energy generated by hoisting collisions during installation, avoiding damage caused by direct rigid impact between the transformer box shell and the side plate; during operation, it attenuates the vibration transmission of the equipment through the elastic deformation of the material, reducing noise and extending the structural life, achieving a dual protection effect of rigidity and flexibility.

[0021] Furthermore, the inclined angle of the wedge block matches the inclined angle of the inner wall of the first inclined groove, and the surface of the wedge block is provided with anti-slip texture. When the pressure strip is fixed to the base by bolts, the wedge block uses extrusion force to firmly press the prefabricated transformer box against the side plate.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The inclined plane angle matching design utilizes the mechanical self-locking principle to automatically generate increasing compressive force during bolt tightening, adapting to substations of different sizes and compensating for manufacturing errors; the anti-slip texture increases the friction between the wedge and the inclined groove contact surface, preventing loosening due to vibration and ensuring long-term stability of the fastening state, making it especially suitable for high-vibration environments.

[0024] This utility model provides a prefabricated substation with an adaptive disassembly and assembly structure. It has the following beneficial effects:

[0025] The transformer box uses the lower limiting post and the inclined groove of the side plate to form a dual positioning of inclined guidance and horizontal limitation. During installation, it can be pushed in along the inclined groove without complicated alignment, which greatly shortens the installation time. The wedge blocks at both ends of the pressure strip match the inner wall of the inclined groove. When fixing the pressure strip, the wedge blocks press the transformer box tightly through the pressure of the inclined surface, which can automatically compensate for dimensional errors and improve versatility.

[0026] The anti-slip texture on the wedge surface enhances friction and prevents slippage, making it suitable for harsh outdoor environments; the base is connected to the concrete foundation through a limiting seat, and together with the bolt-fixed pressure strip, it forms a rigid connection system that can withstand large loads.

[0027] The multi-limit design prevents the transformer box from shifting in both horizontal and vertical directions, effectively resisting transportation bumps and equipment operation vibrations; the rubber elastic buffer layer on the inside of the side plate can absorb the installation impact force and attenuate the vibration transmission during equipment operation, reducing noise and extending the structural life.

[0036] 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.

[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A prefabricated substation with an adaptive disassembly and assembly structure includes a prefabricated transformer box 1, which is mounted on a base 3 via a pressure strip 2. Side plates 301 are provided on both sides of the base 3. An elastic buffer layer is provided on the surface of the side plate 301 facing the prefabricated transformer box 1. This elastic buffer layer buffers the impact force during the installation of the prefabricated transformer box 1. During installation, the elastic buffer layer absorbs the kinetic energy generated by hoisting collisions, preventing damage caused by direct rigid impact between the transformer box casing and the side plate 301. During operation, the elastic deformation of the material attenuates vibration transmission, reducing noise and extending the structural lifespan, achieving a dual protection effect combining rigidity and flexibility. The two ends of the side plate 301 are provided with a first inclined groove 304 and a second inclined groove 305. A limiting post 101 is provided at the bottom of the prefabricated transformer box 1. The prefabricated transformer box 1 is connected to the second inclined groove 305 of the side plate 301 via the limiting post 101 and the prefabricated transformer box 1. The prefabricated transformer box 1 cooperates with the first inclined groove 304 and is guided and limited on the base 3. The pressure strip 2 has wedges 201 at both ends. The wedges 201 are located in the gap between the first inclined groove 304 and the prefabricated transformer box 1 at both ends of the side plate 301. The inclined angle of the wedge 201 matches the inclined angle of the inner wall of the first inclined groove 304, and the surface of the wedge 201 is provided with anti-slip texture. When the pressure strip 2 is fixed to the base 3 by bolts, the wedges 201 use extrusion force to firmly press the prefabricated transformer box 1 against the side plate 301. The inclined angle matching design uses the mechanical self-locking principle to make the wedges 201 automatically generate increasing extrusion force during the bolt tightening process, which can adapt to transformer boxes of different sizes and compensate for manufacturing errors. The anti-slip texture increases the friction between the wedges 201 and the inclined groove contact surface, prevents loosening caused by vibration, and ensures long-term stability of the fastening state, which is especially suitable for high vibration environments.

[0040] Example 2

[0041] To achieve reliable vertical limiting of the prefabricated transformer box, for example, such as Figures 1 to 4 As shown, this utility model also includes: a groove 202 is provided on the pressure strip 2, and the position and size of the groove 202 are adapted to the position and size of the limiting post 101. The pressure strip 2 limits the limiting post 101 of the prefabricated transformer box 1 through the groove 202. Through the precise adaptation of the groove 202 and the limiting post 101, a rigid limiting structure in the vertical direction is formed to prevent the prefabricated transformer box 1 from jumping up and down during equipment operation or transportation. At the same time, it provides a stable force reference for the lateral wedging of the pressure strip 2 and avoids the accumulation of installation errors caused by vertical displacement.

[0042] Example 3

[0043] To improve the connection strength between the base and the foundation and the installation efficiency, for example, such as Figures 1 to 4 As shown, this utility model also includes: a limiting seat 302 is provided at the bottom end of the base 3, and the base 3 is installed on the concrete seat through the limiting seat 302. The embedded connection between the limiting seat 302 and the concrete seat forms a composite force system that resists pull-out and shear, which significantly enhances the connection strength between the base 3 and the foundation and can withstand larger loads. At the same time, the geometry of the limiting seat 302 can assist the base 3 in quickly aligning horizontally, reducing the leveling process during installation and improving construction efficiency. The base 3 is provided with fixing holes 303, and the base 3 is connected and fixed to the pressure strip 2 through the fixing holes 303 and bolts. The cooperation between the fixing holes 303 and the bolts provides a reliable mechanical connection fulcrum for the pressure strip 2, so that the pressure strip 2 can convert the vertical tension of the bolt into lateral compressive force during the wedging process. The standardized layout of the fixing holes 303 facilitates the quick positioning and installation of the pressure strip 2, is compatible with bolts and fasteners of different specifications, and improves the interchangeability of components and the convenience of maintenance.

[0044] Working principle:

[0045] The base 3 is installed on the concrete foundation, and the limiting seat 302 cooperates with the concrete seat to ensure that the base 3 is level and stable. The embedded connection between the limiting seat 302 and the concrete enhances the pull-out and shear resistance and improves the overall stability.

[0046] The prefabricated transformer box 1 is lifted and its lower limiting post 101 is aligned with the second inclined groove 305 of the side plate 301. It is then slowly pushed in along the inclined surface of the groove. The guiding function of the inclined groove guides the transformer box to automatically align, and the cooperation between the limiting post 101 and the inclined groove restricts horizontal displacement, simplifying the installation and alignment process.

[0047] The pressure strip 2 is inserted into the limiting post 101 of the transformer box, ensuring that the slot 202 and the limiting post 101 are fully engaged, thus limiting the vertical displacement of the transformer box. Then, the pressure strip 2 is pushed with bolts to clamp the pre-installed transformer box 1. During the bolt tightening process, the wedges 201 at both ends of the pressure strip 2 slide along the inclined surface of the first inclined groove 304, generating lateral compressive force to firmly press the transformer box against the side plate 301. The wedge angle matching design with the inclined surface of the groove utilizes the mechanical self-locking principle, achieving adaptive tightening without precise control of the bolt torque, thus compensating for component manufacturing errors.

[0048] The elastic buffer layer on the inner side of the side plate 301 undergoes elastic deformation when the transformer box is squeezed by the wedge block 201. On the one hand, it absorbs the impact force during the installation process and protects the equipment shell; on the other hand, it attenuates vibration transmission, reduces noise and extends the structural life during equipment operation.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
