Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, and particularly relates to an assembly structure for the outer shell of a prefabricated substation. Background Technology

[0002] A prefabricated substation is a compact, complete set of power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices into a sealed steel structure enclosure. It features electromechanical integration, fully enclosed operation, and mobility, and is widely used in urban power grids, industry, and new energy fields. However, before it can be put into use, its enclosure needs to be assembled.

[0003] Chinese patent CN218216305U discloses a shell connection structure for a prefabricated substation. The patent describes a structure "related to the field of prefabricated substation technology, including a box and a base. The bottom of the box is provided with a plug-in block, and the plug-in block has a locking groove. The upper surface of the base has a plug-in groove adapted to the plug-in block. A locking component that slides horizontally along the base is provided in the plug-in groove. When the plug-in block is pressed down, the locking component inserts into the locking groove to lock the box. This invention, through the combination of the plug-in block, the plug-in groove, and the locking component, utilizes the weight of the box itself. When the plug-in block is installed into the plug-in groove, the locking component is locked in the locking groove, thus fixing the box and the base. This design is convenient, time-saving, and labor-saving. It achieves a fixed connection between the box and the base simultaneously with the installation of the box, enabling rapid installation of the box and the base."

[0004] However, the above solution still uses a single unit for the enclosure, resulting in a large overall size and inconvenient transportation. Furthermore, while multiple locking components are used to secure the enclosure to the base plate, in actual operation, the first spring's elasticity causes the wedge block to remain inside the insertion slot after the locking plate is released. Therefore, during disassembly, multiple workers need to pull the locking plate simultaneously to ensure the wedge block is in place; otherwise, it will hinder the insertion block from being pulled out. However, this simultaneous pulling by multiple workers results in unnecessary manpower waste and inconvenience in overall assembly. Therefore, designing a modular substation enclosure assembly structure is essential. Utility Model Content

[0007] The installation assembly includes: slots formed at four corners at one end of the top plate and the bottom plate; a fixing groove formed inside the top plate and the bottom plate on one side of the slots; a positioning block extending into the slots slidably connected inside the fixing grooves; a sliding rod extending outside the fixing grooves fixedly connected to one end of the positioning block; a pulling block rotatably connected to one end of the sliding rod; an installation spring wound around the surface of the sliding rod; the two ends of the installation spring being fixedly connected to the inner wall of the fixing groove and one side of the positioning block, respectively; and a locking block fixedly connected to the top and bottom of the column, with a positioning groove formed on one side of the locking block.

[0008] Preferably, the inner wall of the fixing groove is provided with a limiting groove, and the two ends of one side of the positioning block are fixedly connected with limiting blocks that slide in cooperation with the inside of the limiting groove.

[0009] Preferably, the positioning block and the interior of the positioning groove form an engaging structure, the locking block and the interior of the locking groove form an engaging structure, and one side of the locking groove, positioning block, positioning groove and locking block are arc-shaped.

[0010] Preferably, the top plate and the bottom plate are fixedly connected to both sides of a fixing plate, and the bottom ends of the fixing plates are fixedly connected to both sides of a limiting piece, and one end of the pulling block and the inside of the limiting piece form an engaging structure.

[0017] 1. The modular design of the top plate, front plate, columns, bottom plate, side plates, and rear plate allows for modular transportation, reducing transportation difficulties. The use of mounting components, slides, and sliding plates enables rapid assembly and fixation, improving the assembly efficiency of the prefabricated substation casing. Furthermore, during disassembly, the engagement of the pull block with one of the limiting plates ensures the pull block is locked in place after being pulled, preventing the positioning block from sliding into the positioning groove due to the spring force after the pull block is released. This avoids the inconvenience of requiring multiple workers to pull simultaneously, thus improving disassembly efficiency.

[0018] 2. By setting up the baffle, the gap between the front panel, side panel and rear panel and the column can be blocked to achieve initial sealing. Then, the sealing gasket is used to improve the sealing performance after the front panel, side panel and rear panel are engaged with the column, thereby improving the overall sealing performance after assembly and improving its practicality.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Example 1

[0028] A preferred embodiment of the box-type substation enclosure assembly structure provided by this utility model is, for example... Figures 1 to 5 As shown: A prefabricated substation enclosure assembly structure includes a base plate 4; columns 3 located at the four corners of the top of the base plate 4; side plates 6 are provided inside the columns 3 on both sides of the top of the base plate 4; a front plate 2 is provided inside the column 3 at one end of the top of the base plate 4; a rear plate 7 is provided inside the column 3 at the other end of the top of the base plate 4; a top plate 1 is provided at the top of the front plate 2, columns 3, side plates 6 and rear plate 7; and mounting components 5 are assembled at both ends of the top plate 1, columns 3 and base plate 4, which are used to realize the quick snap-fit ​​and disassembly of the top plate 1, columns 3 and base plate 4.

[0029] The mounting assembly 5 includes: slots 501 at the four corners of one end of the top plate 1 and the bottom plate 4; a fixing groove 505 inside the top plate 1 and the bottom plate 4 on one side of the slots 501; a positioning block 510 extending into the slots 501 and slidably connected inside the fixing grooves 505; a sliding rod 507 extending out of the fixing grooves 505 and rotatably connected to one end of the sliding rod 507; a mounting spring 508 wrapped around the surface of the sliding rod 507; and two ends of the mounting spring 508 being fixedly connected to the inner wall of the fixing grooves 505 and one side of the positioning block 510, respectively; and a locking block 512 fixedly connected to the top and bottom of the column 3, with a positioning groove 511 on one side of the locking block 512.

[0030] It should be noted that some existing prefabricated substation enclosure assembly structures still have certain shortcomings in actual use. In the comparison documents, the enclosure is still a single unit, resulting in a large overall size and inconvenient transportation. In addition, multiple locking components are set to lock and fix the enclosure to the base plate 4. However, in actual operation, due to the elastic force of the first spring, the wedge block will be inside the insertion slot after the locking plate is released. Therefore, during disassembly, multiple workers need to pull the locking plate at the same time to ensure that the wedge block moves into place. Otherwise, it will hinder the insertion block from being pulled out. However, the simultaneous pulling by multiple workers will cause unnecessary waste of manpower, resulting in inconvenience in the overall assembly.

[0031] In this embodiment, the base plate 4 is installed in a suitable position. Then, the pull block 506 is rotated and separated from the limiting piece 504. Next, the column 3 is placed on the top of the base plate 4, and the locking block 512 is engaged with the slot 501. This causes the positioning block 510 to slide and compress the mounting spring 508. After the locking block 512 is fully engaged with the slot 501, the elastic force of the mounting spring 508 is used to make the positioning block 510 slide into the positioning groove 511, thus fixing the column 3 to the top of the base plate 4. Then, using the sliding plate 9 and the sliding groove 8, the front plate 2, side plate 6, and rear plate 7 are inserted and installed between the columns 3. Finally, the top plate 1 is placed on the top of the column 3. Repeat the above operations to achieve rapid assembly of top plate 1, front plate 2, column 3, bottom plate 4, side plate 6, and rear plate 7. Use the shielding plate 10 to cover the gap between the front plate 2, side plate 6, and rear plate 7 and the column 3. At the same time, use the sealing gasket 11 to improve the sealing performance after assembly. When disassembly is required, first move the pull block 506 to drive the slide rod 507 and positioning block 510 to slide and compress the installation spring 508 until it is completely disengaged from the inside of the slot 501. Then rotate the pull block 506 to lock it into a limiting piece 504 to prevent the positioning block 510 from sliding into the slot 501 due to the elastic force of the installation spring 508 after the pull block 506 is released. Then the disassembly operation can be performed in sequence.

[0032] In a further preferred embodiment of the present invention, a limiting groove 503 is provided on the inner wall of the fixing groove 505, and a limiting block 509 is fixedly connected to both ends of one side of the positioning block 510 and slides in cooperation with the inside of the limiting groove 503.

[0033] In this embodiment, the smoothness of the back-and-forth sliding of the positioning block 510 is improved by utilizing the sliding between the limiting block 509 and the limiting groove 503.

[0034] In a further preferred embodiment of the present invention, the positioning block 510 and the positioning groove 511 form an engaging structure, and the locking block 512 and the slot 501 form an engaging structure. One side of the slot 501, the positioning block 510, the positioning groove 511 and the locking block 512 are arc-shaped.

[0035] In this embodiment, the arc-shaped slot 501, positioning block 510, positioning groove 511 and slot 512 are used so that when the slot 512 is engaged with the slot 501, the positioning block 510 will automatically slide.

[0036] In a further preferred embodiment of the present invention, a fixing plate 502 is fixedly connected to both sides of the top plate 1 and the bottom plate 4, and a limiting piece 504 is fixedly connected to both sides of the bottom end of the fixing plate 502. A locking structure is formed between one end of the pulling block 506 and the inside of the limiting piece 504.

[0037] In this embodiment, the sliding rod 507 and the positioning block 510 are fixed after sliding by the engagement between the pulling block 506 and the two limiting pieces 504.

[0038] In a further preferred embodiment of the present invention, one side of the fixing plate 502 is inclined, and the width of the fixing plate 502 is greater than the width of the pulling block 506.

[0039] In this embodiment, the inclined fixing plate 502 can be used to shield the pull blocks 506 and slide rods 507 at the four locations on the base plate from rain.

Figures 1 to 5 As shown: Slide grooves 8 are provided on both sides of the column 3, and sealing gaskets 11 are fixedly connected to the inner walls of the column 3 on both sides of the slide grooves 8. Slide plates 9 are fixedly connected to both ends of the front plate 2, side plate 6 and rear plate 7.

[0042] In this embodiment, the gap between the front plate 2, side plate 6 and rear plate 7 and the column 3 is blocked by the baffle plate 10, and the sealing gasket 11 is used to improve the sealing performance after the front plate 2, side plate 6 and rear plate 7 are engaged and installed with the column 3, thereby improving the overall sealing performance after assembly.

[0043] In a further preferred embodiment of the present invention, a sliding engagement structure is formed between the interior of the slide plate 9 and the slide groove 8, and the slide groove 8 and the slide plate 9 are rectangular in shape.

[0044] In this embodiment, the sliding engagement between the slide plate 9 and the inside of the slide groove 8 is used to achieve the sliding assembly between the front plate 2, the side plate 6 and the rear plate 7 and the column 3.

[0045] In a further preferred embodiment of the present invention, a baffle plate 10 is fixedly connected to one end of the front plate 2, the side plate 6 and the rear plate 7, and the length and width of the baffle plate 10 are greater than the length and width of the front plate 2, the side plate 6 and the rear plate 7, respectively.

[0046] In this embodiment, a large-area shielding plate 10 is used to facilitate the shielding and sealing of the gaps between the front plate 2, side plate 6, and rear plate 7 and the column 3.

[0047] In a further preferred embodiment of the present invention, the two sides of the top end of the top plate 1 are inclined, and the area of ​​the cross-section of the bottom end of the top plate 1 is greater than the area of ​​the cross-section of the bottom plate 4.

[0048] In this embodiment, the sloping top plate 1 is used to facilitate the overall protection of the assembled outer shell from rain.

[0049] In summary, the installation component 5 enables the rapid assembly of the top plate 1, the column 3, and the bottom plate 4. Furthermore, the sliding groove 8 and the sliding plate 9 enable the rapid sliding and disassembly of the front plate 2, the side plate 6, and the rear plate 7 with the column 3.
