[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following description, with reference to the accompanying drawings, describes a power distribution cabinet that facilitates maintenance according to an embodiment of the present invention.

[0025] like Figures 1-2 As shown, the power distribution cabinet for easy maintenance according to this utility model embodiment may include: cabinet body 1 and multiple supporting mechanisms 2.

[0026] The cabinet 1 is hinged to a door 11.

[0027] It should be noted that a lock (not shown in the figure) is also provided between the door 11 and the cabinet 1 described in this embodiment. The lock can prevent the door 11 from being opened at will, thereby improving the safety of the power distribution cabinet during use.

[0028] Multiple support mechanisms 2 are installed inside the cabinet 1. Each support mechanism 2 includes two guide rail assemblies 21, two rollers 22, a carrier plate 23, two support rod assemblies 24, and two limiting grooves 25.

[0029] It should be noted that the number of multiple bearing mechanisms 2 can be 2, 3, 4, etc., and the specific number can be determined according to the actual situation. No specific limit is made here.

[0030] Two guide rail assemblies 21 are symmetrically arranged on the inner side wall of the cabinet 1. Two rollers 22 are respectively rotatably connected to the corresponding guide rail assemblies 21. The carrier plate 23 is attached to the two guide rail assemblies 21. Two right-angle connectors 221 are symmetrically arranged on the carrier plate 23. The right-angle connectors 221 are rotatably connected to the rollers 22.

[0031] Understandably, the two right-angle connectors 221 can prevent interference between the carrier plate 23 and the guide rail assembly 21 when the carrier plate 23 is flipped.

[0032] Two support rod assemblies 24 are symmetrically arranged at the bottom of the carrier plate 23, and two limiting grooves 25 are symmetrically arranged on the inner side wall of the cabinet 1.

[0033] Specifically, the electronic components required in the power distribution cabinet (such as busbar system, switchgear, protection devices, measurement and monitoring equipment, and control equipment) are installed on multiple supporting structures 2. After the power distribution cabinet has been running for a period of time, relevant technicians need to open the door 11 to inspect the electronic components inside the cabinet 1.

[0034] As one possible scenario, the relevant technicians pull the carrier plate 23, which drives the roller 22 to move along the guide rail assembly 21. The carrier plate 23 is then removed from the interior of the cabinet 1. Next, the two support rod assemblies 24 are pulled, so that one end of the support rod assembly 24 abuts against the limiting groove 25. The support rod assembly 24 supports the carrier plate 23. At this time, the carrier plate 23 and the electronic components on it are placed horizontally, so that the sides and top of the electronic components are displayed in the field of vision of the relevant technicians.

[0035] As another possible scenario, the relevant technicians reset the support rod assembly 24, and the carrier plate 23 rotates around the roller 22, so that the back of the electronic components is exposed to the relevant technicians' view, which simplifies the operation steps required for maintenance and improves work efficiency.

[0036] In one embodiment of this application, such as Figures 2-5 As shown, the guide rail assembly 21 includes a first guide rail 211, a sleeve rail 212, and a limiting block 214.

[0037] One side of the first guide rail 211 is connected to the side wall of the cabinet 1, the sleeve rail 212 is slidably connected to the first guide rail 211, the outer wall of the first guide rail 211 is provided with a guide groove 213, the limiting block 214 is connected to the sleeve rail 212, and the limiting block 214 is slidably arranged inside the guide groove 213.

[0038] In one embodiment of this application, such as Figures 2-5 As shown, the inside of the sleeve 212 is symmetrically provided with two spring plates 41 arranged in an arc shape. One end of the spring plate 41 is connected to the sleeve 212, and the other end of the spring plate 41 is in contact with the inner wall of the sleeve 212.

[0039] Specifically, when the carrier plate 23 is pulled, the roller 22 first rolls inside the first guide rail 211 until it rolls to the two spring plates 41. The roller 22 is blocked by the spring plates 41, which pushes the sleeve 212 to slide relative to the first guide rail 211. At the same time, the limiting block 214 slides inside the guide groove 213. After the sleeve 212 extends, the relevant technicians apply force to make the roller 22 pass over the two spring plates 41. At this time, it indicates that the carrier plate 23 has moved to the preset position, and the relevant technicians can perform maintenance operations on the electronic components on the carrier plate 23.

[0040] When the carrier plate 23 is reset, due to the restriction of the spring plate 41, the relevant technicians push the carrier plate 23, the sleeve 212 resets first, and then the roller 22 passes over the two spring plates 41, so that the carrier plate 23 is smoothly pushed to the initial position.

[0041] As a possible scenario, in order to ensure the stability of the operation of electronic components, two spring plates 41 with an arc-shaped structure can be arranged at one end of the first guide rail 211 near the back of the cabinet 1. After the roller 22 is reset, the spring plates 41 can limit the roller 22.

[0042] In one embodiment of this utility model, such as Figure 3 As shown, the support rod assembly 24 includes a lug 241, a telescopic rod 242, and a stop bar 243.

[0043] Among them, the lug 241 is connected to the carrier plate 23, one end of the telescopic rod 242 is pivotally connected to the lug 241, and the stop bar 243 is slidably disposed at the other end of the telescopic rod 242.

[0044] It should be noted that the telescopic rod 242 described in this embodiment has a self-locking structure, such as a spring pin self-locking structure. Its specific working principle has been disclosed in the prior art, so it will not be described in detail here.

[0045] It should be noted that the stop bar 243 can slide to one end of the limiting groove 25 and abut against the inside of the limiting groove 25, while the stop bar 243 can slide to the end away from the limiting groove 25 to facilitate reset and avoid interference.

[0046] In one embodiment of this utility model, such as Figure 6 As shown, two plates 32 are symmetrically arranged at the bottom of the carrier plate 23. A groove 33 is provided on one side of the plate 32. A protrusion 31 is provided on the outer wall of the telescopic rod 242, and the protrusion 31 abuts against the inside of the groove 33.

[0047] Specifically, during the resetting process of the telescopic rod 242, the relevant technicians push the telescopic rod 242, which causes the protrusion 31 to be squeezed into the interior of the groove 33, thereby limiting the position of the support rod assembly 24.

[0048] In one embodiment of this utility model, such as Figure 2 As shown, multiple through slots 231 are provided on the carrier plate 23.

[0049] It is understandable that a through slot 231 is provided on the carrier board 23 to facilitate the installation of electronic components on the carrier board 23 by relevant technicians. The through slot 231 is not subject to... Figure 2 The shape constraints provided can be customized according to the actual situation.

[0050] In summary, the power distribution cabinet of this utility model, which facilitates maintenance, simplifies the maintenance procedures and improves work efficiency by mounting electronic components on a carrier plate, which can be moved out of the cabinet along the guide rail assembly. Furthermore, the carrier plate can be flipped after removal, allowing the back of the electronic components to be displayed in the field of vision of relevant technicians.
