Description

Technical Field

[0001] This application relates to the field of power distribution cabinet technology, and more specifically, to an assembly and connection structure for a low-voltage power distribution cabinet and a power distribution cabinet. Background Technology

[0002] When multiple GGDs are used, they are usually placed in separate GGD cabinets, which has the disadvantages of low space utilization and high material costs.

[0003] Low-voltage switchgear is widely used in power distribution systems, especially in industrial facilities and commercial buildings, for the efficient management of power transmission and distribution. With the growth of electricity demand and the popularization of modular design, the deployment of multiple independent cabinets has become standard practice, promoting the development trend of equipment standardization and flexible configuration to adapt to application scenarios of different scales.

[0004] However, the existing independent cabinet placement method suffers from low space utilization. Each cabinet requires its own floor space, resulting in an excessively large overall layout and increased pressure on installation site requirements. Simultaneously, material costs are high. Because the cabinets are designed and manufactured independently, the lack of structural sharing mechanisms leads to the reuse of components and resource waste, increasing overall manufacturing costs and maintenance burden. These issues limit the economic efficiency and space optimization of the power distribution system, necessitating improvements to enhance efficiency.

[0005] There is currently no effective technical solution to the above problems. Utility Model Content

[0006] The purpose of this application is to provide an assembly connection structure and distribution cabinet for low-voltage distribution cabinets, so as to solve the problems of existing multiple independent cabinets needing to be placed and manufactured separately, occupying more space, and the waste of materials due to the duplication of components.

[0007] In one aspect, this application provides an assembly and connection structure for a low-voltage distribution cabinet, including: a first cabinet base frame, a second cabinet base frame, side partitions, and a center sealing plate;

[0008] The first cabinet base frame and the second cabinet base frame each have a first edge post and a second edge post of the same size, and the first edge post and the second edge post are attached side by side;

[0009] The side partition is fixed on both the first edge post and the second edge post. The side partition on the first edge post is located on the side of the first edge post away from the second edge post, and the side partition on the second edge post is located on the side of the second edge post away from the first edge post.

[0010] The central sealing plate is fixedly connected to the side partition plate on the first edge post and the side partition plate on the second edge post.

[0011] Compared with existing technologies, the low-voltage distribution cabinet assembly and connection structure of this application connects two cabinets by adding side partitions and center sealing plates, so that the cabinets share the support and connection structure, allowing multiple low-voltage distribution cabinets to be compactly spliced ​​together, reducing the overall footprint, avoiding the duplication of component manufacturing, thereby optimizing space utilization and material costs, while enhancing structural stability. It solves the problems of existing multiple independent cabinets needing to be placed and manufactured separately, occupying more space, and the waste of materials due to component duplication.

[0012] The low-voltage distribution cabinet assembly and connection structure includes a first cabinet base frame and a second cabinet base frame with the same height. The top of the middle sealing plate is lower than the top of the first cabinet base frame and partially covers the top crossbeam of the first cabinet base frame. The bottom of the middle sealing plate is higher than the bottom of the first cabinet base frame and partially covers the bottom crossbeam of the first cabinet base frame.

[0013] In the assembly structure of the low-voltage distribution cabinet, the first and second cabinet base frames are set at the same height to ensure a flat mating surface after assembly. The center sealing plate is installed with its top end lower than the top end of the first cabinet base frame and partially covering its top crossbeam, while its bottom end is higher than the bottom end of the first cabinet base frame and partially covering its bottom crossbeam. This position of the center sealing plate avoids extending beyond the upper and lower edge columns of the cabinet, allowing for multiple connections between the center sealing plate and the cabinet base frame, increasing the support area, and achieving a compact spatial layout.

[0014] The low-voltage distribution cabinet assembly and connection structure includes a first edge column and a second edge column with the same width, a middle sealing plate with a width 3-4 times the width of the first edge column, and a side partition with a width 1.5-2 times the width of the first edge column.

[0015] The low-voltage distribution cabinet assembly and connection structure includes multiple side partitions on the first edge column, which are adapted to the layered structure of the first cabinet frame.

[0016] In the assembly and connection structure of the low-voltage distribution cabinet, the central sealing plate is fixedly connected to the side partition plate by a plurality of bolts arranged at equal intervals.

[0017] The low-voltage distribution cabinet assembly and connection structure includes a side partition made of U-shaped channel steel and a center sealing plate made of channel steel with concave bent edges.

[0018] In the assembly and connection structure of the low-voltage distribution cabinet, the channel steel sidewall of the side partition is fixed to the first edge column or the second edge column by bolts.

[0019] The low-voltage distribution cabinet assembly and connection structure wherein the top and bottom ends of the side partition and the middle sealing plate are both provided with side sealing bends.

[0020] The low-voltage distribution cabinet assembly and connection structure wherein the hinges for connecting the doors on the first cabinet base frame and the second cabinet base frame are installed on the side away from the central sealing plate.

[0021] Secondly, this application also provides a power distribution cabinet, including the assembly and connection structure of the low-voltage power distribution cabinet as provided in the first aspect.

[0022] Independently placed power distribution cabinets require separate floor space and repeated manufacturing of components. However, the power distribution cabinet of this application achieves direct connection and space integration between cabinets through an assembly and connection structure, reducing the overall layout size and material redundancy, thereby improving deployment efficiency.

[0023] As can be seen from the above, this application provides an assembly connection structure for a low-voltage distribution cabinet and a distribution cabinet. Compared with the prior art, the assembly connection structure of the low-voltage distribution cabinet in this application connects two cabinets by adding side partitions and center sealing plates, so that the cabinets share the support connection structure, allowing multiple low-voltage distribution cabinets to be compactly spliced ​​together, reducing the overall footprint, avoiding the repeated manufacturing of components, thereby optimizing space utilization and material costs, while enhancing structural stability. This solves the problem that existing multiple independent cabinets need to be placed and manufactured separately, occupying more space and causing material waste due to component duplication.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0034] Firstly, please refer to Figures 1-3 Some embodiments of this application provide an assembly and connection structure for a low-voltage distribution cabinet, including: a first cabinet base frame 1, a second cabinet base frame 2, a side partition 3, and a center sealing plate 4;

[0035] The first cabinet base frame 1 and the second cabinet base frame 2 each have a first edge post 11 and a second edge post 21 of the same size, and the first edge post 11 and the second edge post 21 are attached side by side;

[0036] Side partitions 3 are fixed on both the first edge post 11 and the second edge post 21. The side partitions 3 on the first edge post 11 are located on the side of the first edge post 11 away from the second edge post 21, and the side partitions 3 on the second edge post 21 are located on the side of the second edge post 21 away from the first edge post 11.

[0037] The central sealing plate 4 is fixedly connected to the side partition 3 on the first edge post 11 and the side partition 3 on the second edge post 21.

[0038] Specifically, the first cabinet base frame 1 refers to the main frame of a low-voltage distribution cabinet, which can be implemented using a steel frame as the supporting foundation for the cabinet. Similarly, the second cabinet base frame 2 refers to the main frame of another low-voltage distribution cabinet. The first edge post 11 refers to the edge support component on the first cabinet base frame 1, which can be implemented using rectangular channel steel. In this design, it is used to provide a connection point to ensure a close fit with the second edge post 21. Similarly, the second edge post 21 refers to the edge support component on the second cabinet base frame 2, which can be implemented using a structure with the same dimensions as the first edge post 11. The side partition 3 refers to the plate-like component fixed to the edge post. In this design, it is located on the side of the edge post away from the other cabinet, and is used to provide a connection interface to increase the support area of ​​the center sealing plate 4. The center sealing plate 4 refers to the plate-like component connecting the two side partitions 3, which can be implemented using channel steel with bent edges. In this design, it is used to fix the side partitions 3 to open up the interior of the cabinet and improve the overall structural strength.

[0039] Specifically, the first cabinet base frame 1 and the second cabinet base frame 2 are joined side-by-side by their first edge posts 11 and second edge posts 21; the side partitions 3 are fixed to the outside of the edge posts, i.e., the side facing away from the other cabinet; the center sealing plate 4 is fixedly connected to the two side partitions 3, splicing the two cabinets together. The interior of the cabinets is opened up, reducing the independent space occupied, and the side wall between the two cabinets is removed and converted, with the center sealing plate 4 serving as the main support; the connection between the side partitions 3 and the center sealing plate 4 increases the connection and support area of ​​the center sealing plate 4, further improving the strength of the assembled structure.

[0040] Compared with the prior art, the low-voltage distribution cabinet assembly and connection structure of this application connects two cabinets by adding a side partition 3 and a central sealing plate 4, so that the cabinets share the support and connection structure, allowing multiple low-voltage distribution cabinets to be compactly spliced ​​together, reducing the overall footprint, avoiding the repeated manufacturing of components, thereby optimizing space utilization and material costs, while enhancing structural stability. It solves the problems of existing multiple independent cabinets needing to be placed and manufactured separately, occupying more space, and the waste of materials caused by repeated components.

[0041] In some preferred embodiments, the first cabinet base frame 1 and the second cabinet base frame 2 are at the same height, the top of the middle sealing plate 4 is lower than the top of the first cabinet base frame 1 and partially covers the top crossbeam 12 of the first cabinet base frame 1, and the bottom of the middle sealing plate 4 is higher than the bottom of the first cabinet base frame 1 and partially covers the bottom crossbeam 13 of the first cabinet base frame 1.

[0042] Specifically, the fact that the first cabinet base frame 1 and the second cabinet base frame 2 are at the same height means that the two cabinet base frames have the same height dimension. This can be achieved through standardized manufacturing processes, which helps to ensure alignment and overall structural stability during assembly.

[0043] More specifically, the length of the center sealing plate 4 is designed such that the top end is lower than the top end of the first cabinet base frame 1 and the bottom end is higher than the bottom end of the first cabinet base frame 1. This helps to prevent the center sealing plate 4 from being damaged by external collisions during transportation or operation.

[0044] More specifically, the middle sealing plate 4 partially covers the top beam 12 of the first cabinet base frame 1 and partially covers the bottom beam 13 of the first cabinet base frame 1, so that the middle sealing plate 4 simultaneously supports the edge columns, the top beam 12 and the bottom beam 13, effectively expanding the support area of ​​the middle sealing plate 4 to enhance the structural strength.

[0045] Specifically, in the assembly structure of the low-voltage distribution cabinet, the first cabinet base frame 1 and the second cabinet base frame 2 are set at the same height to ensure that the two cabinets form a flat mating surface after assembly. The middle sealing plate 4 is installed such that its top end is lower than the top end of the first cabinet base frame 1 and partially covers its top crossbeam 12, while its bottom end is higher than the bottom end of the first cabinet base frame 1 and partially covers its bottom crossbeam 13. Thus, the position of the middle sealing plate 4 avoids extending beyond the upper and lower edge columns of the cabinet, allowing the middle sealing plate 4 to form multiple connections with the cabinet base frame, increasing the support area, and achieving a compact spatial layout.

[0046] In some preferred embodiments, the first edge post 11 and the second edge post 21 have the same width, the width of the center sealing plate 4 is 3-4 times the width of the first edge post 11, and the width of the side partition 3 is 1.5-2 times the width of the first edge post 11.

[0047] Specifically, the widths of the center sealing plate 4 and the side partitions 3 are set to a specific multiple of the width of the edge posts, ensuring sufficient area at the connection points during assembly to guarantee stability while avoiding material waste, thereby improving structural stability and reducing costs. This solution achieves a compact layout and material savings through proportional design, sharing the center sealing plate 4 and the side partitions 3 during assembly.

[0048] In some preferred embodiments, the side partitions 3 on the first edge column 11 are multiple pieces and are configured to fit the layered structure of the first cabinet base frame 1. Similarly, the side partitions 3 on the second edge column 21 are multiple pieces and are configured to fit the layered structure of the second cabinet base frame 2.

[0049] Specifically, the layered structure refers to the hierarchical framework formed within the cabinet's base frame, which can be achieved using beams and columns, providing partitioned support in the design. The side partition 3, adapted to the layered structure, is matched to the internal layered framework of the cabinet, achieved by adjusting the position and size of the panels, ensuring the connection structure adapts to the internal component layout in the design.

[0050] Specifically, the side partition 3 is set as multiple pieces and adapted to the layered structure of the cabinet base frame. The side partition 3 is installed on the edge posts and corresponds to the position of the layered frame. During assembly, the connection structure is adjusted to match the layout of the internal components, thereby reducing gap occupation, improving compactness, and reducing material reuse.

[0051] In some preferred embodiments, the central sealing plate 4 is fixedly connected to the side partition plate 3 by a plurality of equally spaced bolts (not shown in the figure).

[0052] Specifically, the central sealing plate 4 is fixed to the side partition plate 3 by multiple equidistant bolts, thereby achieving uniform force distribution at the connection point, ensuring tightness of the connection, supporting the opening of the internal space of the cabinet and the stability of the assembled structure, and solving the problems of space utilization and material waste.

[0053] In some preferred embodiments, the side partition 3 is a U-shaped channel steel, and the central sealing plate 4 is a channel steel with an inwardly concave bent edge 41.

[0054] Specifically, in this embodiment, the central sealing plate 4 is pressed against the side partition plate 3 by the concave bending edge 41, and the connection between the concave bending edge 41 and the side partition plate 3 is locked by bolts to ensure the tightness of the connection and the structural strength of the central sealing plate 4.

[0055] More specifically, U-shaped channel steel refers to steel with a U-shaped cross section; concave bending edge 41 refers to the part of the channel steel edge that bends inward, which can be formed by stamping or bending processes. In the scheme, it is used to directly press against the side partition 3 to achieve seamless fit and ensure tight connection.

[0056] Specifically, the side partition 3 is fixed to the edge column of the cabinet using U-shaped channel steel, and the middle sealing plate 4 is made of channel steel with concave bending edge 41. The concave bending edge 41 is pressed against the side partition 3 to achieve initial positioning. Furthermore, bolts are used to lock the contact surface between the concave bending edge 41 and the side partition 3, so that the two are tightly connected, thereby enhancing the overall strength of the assembly structure and avoiding connection failure due to vibration or load.

[0057] In some preferred embodiments, the channel steel sidewall of the side partition 3 is fixed to the first edge post 11 or the second edge post 21 by bolts (not shown in the figure).

[0058] Specifically, the channel steel sidewall of the side partition 3 is fixed to the first edge post 11 or the second edge post 21 by bolts, thereby achieving a reliable connection, avoiding loosening during assembly, and thus improving the stability of the overall structure.

[0059] Through the above technical solution, this application achieves a stable connection between the side partition 3 and the edge column, improves the strength of the assembled structure, and simplifies the manufacturing process, thereby reducing material costs and optimizing space utilization.

[0060] In some preferred embodiments, the top and bottom ends of the side partition 3 and the center sealing plate 4 are both provided with side sealing bends 42.

[0061] Specifically, the edge sealing bend 42 refers to the bent structure formed at the edge of the sheet metal, which can be achieved by stamping and bending process, and is used to strengthen the edge area and prevent burrs from being generated.

[0062] More specifically, during the assembly of the low-voltage distribution cabinet, the top and bottom ends of the side partition 3 and the middle sealing plate 4 are provided with side sealing bending parts 42. These bending parts enhance local rigidity by increasing the edge thickness and bending angle, preventing deformation or cracking. At the same time, the bending design simplifies the assembly steps, ensures that the plates fit tightly together, reduces space waste, and reduces the frequency of material replacement due to edge damage.

[0063] In some preferred embodiments, hinges 14 for connecting the door on the first cabinet base frame 1 and the second cabinet base frame 2 are installed on the side away from the center sealing plate 4.

[0064] Specifically, after the hinge 14 is installed on the side opposite to the center sealing plate 4, the opening and closing of the door is not obstructed by the center sealing plate 4 during the cabinet assembly process, ensuring normal access to the interior of the cabinet. As a result, the cabinet frame can be arranged closely, reducing the space required for independent cabinet deployment and simplifying the manufacturing process.

[0065] Through the above technical solution, this application solves the problem of door opening and closing obstacles, improves the efficiency of cabinet space utilization, and reduces the difficulty of material reuse and maintenance.

[0066] Secondly, please refer to Figure 4 Some embodiments of this application also provide a power distribution cabinet, including the assembly and connection structure of the low-voltage power distribution cabinet as provided in the first aspect.

[0067] Independently placed power distribution cabinets require separate floor space and repeated manufacturing of components. However, the power distribution cabinet of this application achieves direct connection and space integration between cabinets through an assembly and connection structure, reducing the overall layout size and material redundancy, thereby improving deployment efficiency.

[0069] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
