Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet that is easy to maintain. Background Technology

[0002] In power systems, distribution cabinets, as core equipment for power distribution and control, are widely used in various fields such as industry, commerce, and construction. Traditional distribution cabinets typically adopt an integrated cabinet structure, with side panels fixed to the cabinet body by bolts, welding, or clips. This fixing method ensures the stability and protection of the cabinet structure during normal operation, providing a reliable working environment for the internal electrical components. However, when the electrical components inside the distribution cabinet malfunction and require repair, maintenance personnel need to spend a lot of time using tools to disassemble numerous bolts one by one, which is cumbersome and inefficient. Welded side panels require specialized cutting equipment for removal, which not only increases maintenance costs but may also cause irreversible damage to the cabinet body. Although clip connections are relatively easy to disassemble, they are prone to aging and jamming after long-term use, making side panel disassembly difficult. In addition, even after the side panels are disassembled, some distribution cabinets have narrow internal spaces and compact component layouts, limiting the operating space for maintenance personnel, further extending maintenance time and increasing maintenance difficulty. Utility Model Content

[0003] The purpose of this utility model is to provide a power distribution cabinet that is easy to maintain. It addresses the common problem that power distribution cabinets typically use an integrated cabinet structure, with side panels fixed to the cabinet body via bolts, welding, or snap-fit ​​connections. While this method ensures the stability and protection of the cabinet structure during normal operation and provides a reliable working environment for internal electrical components, it presents challenges. When internal electrical components malfunction and require repair, maintenance personnel must spend considerable time manually removing numerous bolts, a cumbersome and inefficient process. Welded side panels require specialized cutting equipment for removal, increasing maintenance costs and potentially causing irreversible damage to the cabinet. While snap-fit ​​connections offer relatively convenient disassembly, long-term use can lead to aging and jamming of the snaps, making side panel removal difficult. Furthermore, even after side panel removal, some power distribution cabinets have limited internal space and compact component layout, restricting the operator's workspace and further extending maintenance time and increasing the difficulty of repair.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet that is easy to maintain, comprising a cabinet body, side panels on both sides of the cabinet body, limit blocks fixedly connected to both sides of the bottom inner side of the side panels, the surface of the limit blocks contacting the inner wall of the cabinet body, baffle plates fixedly connected to the top of both sides of the inner wall of the cabinet body, the surface of the baffle plates contacting the surface of the side panels, a positioning plate provided on the top of the cabinet body, the inner wall of the positioning plate contacting the surface of the side panels, vertical rods fixedly connected to both sides of the top of the cabinet body, the top of the vertical rods extending through to the top of the positioning plate, the limit plates fixedly connected to the top of the vertical rods, and a support mechanism fixedly connected to the bottom of the positioning plate.

[0005] Preferably, the support mechanism includes a first inclined block, which is fixedly connected to the bottom of the inner wall of the positioning plate. A second inclined block is provided at the bottom of the first inclined block. An electric cylinder is fixedly connected to the right side of the second inclined block, and the bottom of the electric cylinder is fixedly connected to the top of the cabinet.

[0006] Preferably, the bottom of the second inclined block is provided with a support wheel assembly, and the bottom of the support wheel assembly is fixedly connected to the top of the cabinet.

[0007] Preferably, the surface of the inclined block is provided with a weight-reducing groove, and the weight-reducing groove is located at the top of the cabinet.

[0008] Preferably, structural ribs are fixedly connected to both sides of the top of the positioning plate, and the structural ribs are located at the top of the cabinet.

[0009] Preferably, a spring is fixedly connected to the bottom of the limiting plate, and the bottom of the spring is fixedly connected to the top of the positioning plate.

[0010] Preferably, both sides of the cabinet are fixedly connected to a wrapping plate, and the inner wall of the wrapping plate is in contact with the surface of the positioning plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a positioning plate and other structures to the cabinet body, and sets side panels on both sides of the cabinet body. The bottom of the inner side of the side panel contacts the inner wall of the cabinet body through a limiting block, and the top is limited by a baffle plate, forming a double positioning structure. This design can ensure that the side panels can be quickly aligned during installation, and only the top constraint needs to be released during disassembly, simplifying the side panel disassembly and assembly process during maintenance.

[0013] 2. This utility model adds structures such as electric cylinders to the cabinet. The electric cylinder driving method is more convenient than manual adjustment. The extension and retraction of the support mechanism can be quickly realized through the electronic control system, reducing manual operation during maintenance and improving maintenance efficiency.

[0019] 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.

[0020] Please see Figure 1-4 A power distribution cabinet that is easy to maintain includes a cabinet body 1. Side panels 2 are provided on both sides of the cabinet body 1. Limiting blocks 3 are fixedly connected to both sides of the bottom inner side of the side panels 2. The surface of the limiting blocks 3 is in contact with the inner wall of the cabinet body 1. Baffle plates 4 are fixedly connected to the top of both sides of the inner wall of the cabinet body 1. The surface of the baffle plates 4 is in contact with the surface of the side panels 2. A positioning plate 5 is provided on the top of the cabinet body 1. The inner wall of the positioning plate 5 is in contact with the surface of the side panels 2. Vertical rods 6 are fixedly connected to both sides of the top of the cabinet body 1. The top of the vertical rods 6 extends through to the top of the positioning plate 5. A limiting plate 7 is fixedly connected to the top of the vertical rods 6. A support mechanism 8 is fixedly connected to the bottom of the positioning plate 5.

[0021] Please see Figure 1-4 The support mechanism 8 includes a first inclined block 81, which is fixedly connected to the bottom of the inner wall of the positioning plate 5. A second inclined block 82 is provided at the bottom of the first inclined block 81. An electric cylinder 83 is fixedly connected to the right side of the second inclined block 82. The bottom of the electric cylinder 83 is fixedly connected to the top of the cabinet 1.

[0022] Furthermore, through the setting of inclined block 1 81 and inclined block 2 82, the support mechanism 8 adopts the design of inclined block 1 81 and inclined block 2 82 cooperating with electric cylinder 83. When electric cylinder 83 drives inclined block 2 82 to move, it can push inclined block 1 81 upward through the inclined surface of the inclined block, thereby driving the positioning plate 5 to be pressed upward. This structure can adjust the support force according to actual needs and adapt to the stability requirements of side plate 2 under different working conditions. In particular, the support force can be quickly released by electric cylinder 83 during maintenance, which facilitates the disassembly of side plate 2.

[0023] Please see Figure 1-4 The bottom of the inclined block 82 is provided with a support wheel assembly 9, and the bottom of the support wheel assembly 9 is fixedly connected to the top of the cabinet 1.

[0024] Furthermore, by setting the support wheel assembly 9, the frictional resistance can be reduced when the electric cylinder 83 drives the second inclined block 82 to move, making the sliding of the second inclined block 82 smoother, avoiding drive jamming or structural wear caused by excessive friction, and extending the service life of the support mechanism 8.

[0025] Please see Figure 1-4 The surface of the inclined block 81 is provided with a weight-reducing groove 10, which is located at the top of the cabinet 1.

[0026] Furthermore, by setting the weight reduction groove 10, the amount of material used can be reduced without affecting the structural strength, and the load on the top of the distribution cabinet can be reduced. This is especially suitable for scenarios that require frequent movement or have weight requirements, while also reducing the driving load of the electric cylinder 83.

[0027] Please see Figure 1-4 Structural ribs 11 are fixedly connected to both sides of the top of the positioning plate 5, and the structural ribs 11 are located at the top of the cabinet 1.

[0028] Furthermore, by setting the structural ribs 11, its bending strength and stiffness can be improved, preventing the positioning plate 5 from bending and deforming when subjected to the upward thrust of the inclined block 81 or external load, ensuring the positioning accuracy of the positioning plate 5 on the side plate 2, and avoiding the side plate 2 from loosening due to the deformation of the positioning plate 5.

[0029] Please see Figure 1-4 A spring 12 is fixedly connected to the bottom of the limiting plate 7, and the bottom of the spring 12 is fixedly connected to the top of the positioning plate 5.

[0030] Furthermore, the spring 12 allows for an elastic connection between the positioning plate 5 and the limiting plate 7. When the side plate 2 deforms due to thermal expansion and contraction or stress, the spring 12 can automatically adjust the position of the positioning plate 5 to compensate for the gap and maintain the clamping force of the side plate 2. At the same time, the elasticity of the spring 12 can absorb external vibrations, reduce the loosening of the side plate 2 or the falling off of parts caused by vibrations, and improve the stability of the power distribution cabinet operation.

[0031] Please see Figure 1-4 Both sides of the cabinet 1 are fixedly connected with a wrapping plate 13, and the inner wall of the wrapping plate 13 is in contact with the surface of the positioning plate 5.

[0032] Furthermore, by setting the wrapping plate 13, the positioning plate 5 can be limited, preventing the positioning plate 5 from tilting during movement and improving the movement stability of the positioning plate 5.

[0033] The specific implementation process of this utility model is as follows: When in use, place the cabinet 1 in the predetermined installation position, ensuring that the cabinet 1 is stable and level. Align the side panel 2 with the two sides of the cabinet 1, so that the limiting block 3 at the bottom of the inner side of the side panel 2 fits against the inner wall of the cabinet 1 to achieve initial positioning. Push the side panel 2 upward until the top of the side panel 2 contacts the cover plate 4 on both sides of the inner wall of the cabinet 1, completing the upper and lower limit installation of the side panel 2. Start the electric cylinder 83 of the support mechanism 8, and control the electric cylinder 83 to drive the second inclined block 82 to move, so that the first inclined block 81 separates from the second inclined block 82. The positioning plate 5 descends under the action of gravity and spring 12, clamping the side panel 2. Move the second inclined block 82 in the opposite direction so that the first inclined block 81 drives the positioning plate 5 to move upward, and the side panel 2 can be removed from the two sides of the cabinet 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
