[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] In order to facilitate the staff to regularly inspect and repair the electrical components in the distribution cabinet, the maintenance space can be adaptively expanded according to the actual situation to improve the maintenance efficiency. This embodiment provides a distribution cabinet, which is combined with Figures 1 to 5 The specific contents of this embodiment are described in detail.

[0042] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a power distribution cabinet that is easy to maintain, and the power distribution cabinet includes a cabinet body, a drive module 50 and a wire-releasing module 60. The cabinet body includes a rear panel 10, a top panel 20, a bottom panel 40 and two groups of side panels 30. The top panel 20 and the bottom panel 40 are respectively arranged at opposite ends of the rear panel 10, and the two groups of side panels 30 are respectively located at opposite sides of the rear panel 10. The electrical components installed on the rear panel 10 and the electrical components installed on the side panels 30 are connected by wires. The drive module 50 is arranged on the cabinet body, and the drive module 50 is used to drive the two groups of side panels 30 to move closer to or away from each other. The wire-releasing module 60 is arranged on the cabinet body. When the two groups of side panels 30 move away from each other, the wire-releasing module 60 is used to release the wires. When the two groups of side panels 30 move closer to each other, the wire-releasing module 60 is used to reel in the wires.

[0043] In short, the power distribution cabinet provided in this embodiment, when the power distribution cabinet is working normally, the two groups of side panels 30 are respectively attached to the left and right sides of the rear panel 10, and when it is necessary to inspect and maintain the electrical components inside the cabinet, the driving module 50 is used to drive the two groups of side panels 30 to move away from each other, so that the internal space of the cabinet can be adaptively expanded, so that the staff can smoothly perform inspection and maintenance operations on the electrical components; in some cases, the electrical components installed on the front side of the rear panel 10 and the electrical components installed on the inner wall of the side panel 30 are connected by wires to realize signal transmission. When the two groups of side panels 30 move away from each other, the electrical components on the front side of the rear panel 10 and the electrical components on the inner wall of the side panel 30 move away from each other synchronously, and the corresponding wires are easily pulled and then detached from the corresponding electrical components. Therefore, by arranging a wire-releasing module 60 on the cabinet, when the two groups of side panels 30 move away from each other, the wire-releasing module 60 is used to release the corresponding wires, so that the wires can be adaptively stretched, thereby preventing the wires from detaching from the corresponding electrical components, and at the same time avoiding the wires from being subjected to large pulling force and then being broken and damaged.

[0044] For further information, see Figure 1 as well as Figure 2 In one embodiment, the driving module 50 includes two threaded rods 501 and a threaded sleeve 502 with an internal thread. The threaded sleeve 502 is rotatably arranged on the top plate 20. The inner wall surface of each set of side plates 30 is fixedly provided with a threaded rod 501. One end of the threaded rod 501 is threadedly connected to the threaded sleeve 502. The external threads of the two threaded rods 501 have opposite rotation directions. One end of the two threaded rods 501 is located in the threaded sleeve 502. Since the external threads of the two threaded rods 501 have opposite rotation directions, when the threaded sleeve 502 is rotated, the two threaded rods 501 can move closer to or farther from each other, thereby driving the corresponding side plate 30 to move, so as to adjust the size of the maintenance space.

[0045] Furthermore, the drive module 50 further comprises a motor 503, a driving bevel gear 504 and a transmission bevel gear 505. The fixed end of the motor 503 is connected to the top plate 20, the driving bevel gear 504 is coaxially connected to the output end of the motor 503, the transmission bevel gear 505 is fixedly sleeved on the threaded sleeve 502, and the driving bevel gear 504 is meshed and connected with the transmission bevel gear 505. When it is necessary to inspect and maintain the electrical components inside the power distribution cabinet, the staff starts the motor 503, the motor 503 drives the driving bevel gear 504 to rotate, and the meshing action of the driving bevel gear 504 and the transmission bevel gear 505 is used to drive the threaded sleeve 502 to rotate, and then the threaded sleeve 502 and the two sets of threaded rods 501 are used to drive the two sets of side panels 30 to move away from each other. When the two sets of side panels 30 move away from each other, the internal space of the entire cabinet can be increased, so that the staff can smoothly inspect and maintain the electrical components in the cabinet.

[0046] Furthermore, two support plates 202 are provided on the top plate 20, and the threaded sleeve 502 is rotatably connected to the two support plates 202. The threaded sleeve 502 transversely penetrates the support plate 202 and rotatably cooperates with the support plate 202, and the threaded sleeve 502 is supported by the support plate 202, so that the driving bevel gear 504 can smoothly drive the threaded sleeve 502 to rotate when it is meshed with the transmission bevel gear 505.

[0047] Furthermore, a slide plate 301 is provided on the inner wall surface of each set of side panels 30, and a guide rail 201 extending along the moving direction of the side panels 30 is provided on the top panel 20, and the slide plate 301 is slidably connected to the guide rail 201. The sliding fit between the slide plate 301 and the guide rail 201 can provide a guiding effect on the side panels 30, so that when the threaded sleeve 502 is threadedly fitted with the threaded rod 501, the side panels 30 can be smoothly moved away from the rear panel 10.

[0048] For further information, see Figure 5The wire-paying module 60 includes a wire-paying reel 601, a winding post 602, a support shaft 604 and a transmission mechanism. One end of the support shaft 604 is rotatably connected to the rear plate 10, and the other end of the support shaft 604 is fixedly connected to the wire-paying reel 601. Two groups of winding posts 602 are provided. The two groups of winding posts 602 are fixedly arranged at an eccentric position on one side of the wire-paying reel 601. The two groups of winding posts 602 are symmetrically distributed about the center of the wire-paying reel 601. The support shaft 604 and one of the side plates 30 are connected through a transmission mechanism. When the electrical components on the front side of the rear panel 10 need to be connected to the electrical components on the inner wall of the side panel 30 through a wire, one end of the wire can be connected to the electrical components on the front side of the rear panel 10 first, and then the wire is pulled so that the wire passes through the two sets of winding posts 602 in sequence, and then the other end of the wire is connected to the electrical components on the inner wall of the side panel 30. The connected wire is limited to a bent state by the two sets of winding posts 602, and the wires limited by the two sets of winding posts 602 are distributed in an orderly manner to prevent the wires from being too scattered inside the cabinet. When the electrical components need to be inspected and maintained, the motor 503 is started to drive the two sets of side panels 30 away from each other, and the side panels 30 drive the support shaft 604, the wire reel 601 and the two sets of winding posts 602 to rotate through the transmission mechanism. When the two sets of winding posts 602 rotate, the wires limited to a bent state by the two sets of winding posts 602 are pulled and gradually straightened and stretched, thereby preventing the wires from being separated from the corresponding electrical components when the two sets of side panels 30 are away from each other, and at the same time avoiding the wires from being broken and damaged. When the electrical components in the cabinet are overhauled, the motor 503 can drive the driving bevel gear 504 to rotate in the reverse direction, and utilize the reverse meshing action of the driving bevel gear 504 and the transmission bevel gear 505 to drive the threaded sleeve 502 to rotate in the reverse direction, and through the reverse thread cooperation of the threaded sleeve 502 and the two groups of threaded rods 501, the two groups of side panels 30 are driven to approach each other, so that the two groups of side panels 30 are re-attached to the left and right sides of the rear plate 10. When the two groups of side panels 30 approach each other, the transmission mechanism can be driven to work in the reverse direction, thereby driving the support shaft 604, the wire reel 601 and the two groups of winding poles 602 to rotate in the reverse direction. When the two groups of winding poles 602 rotate in the reverse direction, the wires are re-bent to ensure the orderly re-wiring of the wires.

[0049] Exemplarily, the transmission mechanism includes a gear 605 and a rack 606, wherein the gear 605 is fixedly arranged outside the support shaft 604, one end of the rack 606 is fixedly connected to the inner wall of the side plate 30, and the other end of the rack 606 extends to one side of the gear 605 and meshes with the gear 605. When the electrical components need to be repaired and maintained, the motor 503 is started to drive the two sets of side plates 30 away from each other, and the side plates 30 drive the rack 606 to move, and the meshing action of the rack 606 and the gear 605 drives the support shaft 604, the pay-off drum 601 and the two sets of winding posts 602 to rotate. When the electrical components in the cabinet are overhauled, the motor 503 rotates in the reverse direction, so that the two groups of side panels 30 are re-attached to the left and right sides of the rear panel 10. When the two groups of side panels 30 approach each other, the rack 606 can be driven to move in the reverse direction, and the reverse meshing action of the rack 606 and the gear 605 can drive the support shaft 604, the wire reel 601 and the two groups of winding poles 602 to rotate in the reverse direction.

[0050] Furthermore, a limiting end plate 603 is fixedly provided at one end of the two sets of winding posts 602 away from the wire pay-off reel 601, and the diameter of the limiting end plate 603 is larger than the diameter of the winding posts 602. By adding the limiting end plate 603 to the winding posts 602, the wire can be prevented from slipping out of one end of the winding posts 602, thereby preventing the wire from loosening.

[0051] Furthermore, the cabinet body further includes a door panel 70, which is arranged at one end of the top panel 20 and the bottom panel 40 away from the rear panel 10, and the rear panel 10, the top panel 20, the side panels 30, the bottom panel 40 and the door panel 70 are arranged to form a receiving space. When the power distribution cabinet is working normally, the two sets of side panels 30 are respectively attached to the left and right sides of the rear panel 10, and the door panel 70 covers the front of the top panel 20 and the bottom panel 40. At this time, a closed cabinet structure is formed between the rear panel 10, the top panel 20, the bottom panel 40, the door panel 70 and the two sets of side panels 30. When it is necessary to inspect and maintain the electrical components inside the cabinet body, the staff can open the door panel 70.

[0052] Furthermore, if Figure 4 As shown, the edges of the two sets of side panels 30 facing each other are both provided with an annular sealing strip 302. When the two sets of side panels 30 are attached to the left and right sides of the rear panel 10, the gap between the side panels 30 and the rear panel 10 can be sealed by adding the annular sealing strip 302, thereby preventing external dust and rain from entering the inner side of the cabinet, and realizing effective protection of the electrical components inside the cabinet.

[0053] Optionally, the annular sealing strip 302 may be, but is not limited to, a rubber strip or a silicone strip, and no further restrictions are made herein.

[0054] In summary, the working principle of the power distribution cabinet in this embodiment is as follows: when the power distribution cabinet is working normally, the two sets of side panels 30 are respectively attached to the left and right sides of the rear panel 10, and the door panel 70 covers the top panel 20 and the front of the bottom panel 40 (such as Figure 3 As shown), a closed cabinet structure is formed between the rear panel 10, the top panel 20, the bottom panel 40, the door panel 70 and the two groups of side panels 30; when it is necessary to inspect and maintain the electrical components inside the cabinet, the staff can open the door panel 70, and then use the drive module 50 to drive the two groups of side panels 30 away from each other, so that the internal space of the cabinet can be adaptively expanded, so that the staff can smoothly inspect and operate the electrical components. In some cases, the electrical components installed on the front side of the rear panel 10 and the electrical components installed on the inner wall of the side panel 30 are connected by wires to realize signal transmission. When the two groups of side panels 30 move away from each other, the electrical components on the front side of the rear panel 10 and the electrical components on the inner wall of the side panel 30 move away from each other synchronously, and the corresponding wires are easily pulled and detached from the corresponding electrical components. Based on this, by setting up the wire-paying module 60, when the two groups of side panels 30 are away from each other, the wire-paying module 60 is used to pay out the corresponding wires, so that the wires can be adaptively stretched, thereby preventing the wires from detaching from the corresponding electrical components, and at the same time preventing the wires from being subjected to large tension and then broken and damaged. Compared with the prior art, when it is necessary to inspect and repair the electrical components inside the distribution cabinet, the internal space of the distribution cabinet can be adaptively expanded so that the staff can obtain more sufficient maintenance space and improve the maintenance efficiency.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
