Description

Technical Field

[0001] The present application relates to the field of power distribution cabinets, and in particular to a power distribution cabinet that is easy to maintain. Background Art

[0002] At present, distribution cabinets are widely used in the distribution systems of power users such as substations, power plants, factories and mines, mainly for the purpose of power conversion, distribution and control of power, lighting and power generation and distribution equipment.

[0003] Regarding the above-mentioned related technologies, there are still defects: a large amount of heat is generated when the electrical components in the cabinet are working. The high temperature of the heating components and the on-site will make the temperature inside the distribution cabinet higher. If the electrical components in the cabinet are damaged, especially during maintenance at night, maintenance personnel need to enter the distribution cabinet to operate when repairing the electrical components inside the distribution cabinet, which is very inconvenient. In addition, since some electrical components are located deep in the distribution cabinet, they are blocked by the cabinet wall of the distribution cabinet, and it is not easy for maintenance personnel to repair them. Therefore, there is room for improvement. Utility Model Content

[0004] In order to facilitate maintenance personnel to maintain electrical components in a power distribution cabinet, the present application provides a power distribution cabinet that is easy to maintain.

[0005] The present application provides a power distribution cabinet that is easy to maintain, which adopts the following technical solution:

[0006] A power distribution cabinet that is easy to maintain, includes a cabinet body with an opening and a cabinet door, a storage rack is slidably connected in the cabinet body, and a cavity is provided on the side wall of the storage rack in contact with the cabinet body; the storage rack is rotatably connected to rotating rods on both sides of the opening, and the ends of the rotating rods are rotatably connected to movable rods, and hand grips are integrally formed at both ends of the movable rod, and the hand grips are provided with hand grip grooves.

[0007] By adopting the above technical solution, electrical components are all mounted on the storage rack. When maintenance personnel need to inspect the electrical components, they can first hold the handpiece and pull the storage rack to move the storage rack out of the cabinet. The electrical components on the storage rack will also be moved out of the cabinet as the storage rack moves, so as to facilitate maintenance by maintenance personnel.

[0008] Optionally, movable cavities for inserting handpieces are opened on two sides of the cabinet body, and limiting plates for limiting the handpiece are provided in the movable cavity. When the handpiece is in close contact with the limiting plate, the slot height of the handgrip groove is higher than the height of the limiting plate.

[0009] By adopting the above technical solution, the limit plate in the movable cavity can fix the handpiece. When the handpiece contacts the limit plate, the handpiece can no longer be rotated out of the cabinet. When the handpiece needs to be used, the maintenance personnel can insert their fingers into the grip groove to rotate the handpiece out of the movable cavity, so as to make the handpiece move again to pull the storage rack.

[0010] Optionally, a plurality of groups of balls are rollingly connected on both sides of the cabinet, and the balls are in close contact with the solid part of the storage rack.

[0011] By adopting the above technical solution, the presence of the ball bearings can reduce the friction between the cabinet and the storage rack, making it easier for maintenance personnel to pull the storage rack.

[0012] Optionally, an upper ring block and a lower ring block are respectively sleeved on the outside of the cabinet body, and the upper ring block and the lower ring block both have door rails. A movable block that can be inserted into the upper ring block or the lower ring block is integrally formed on the cabinet door, and there is a gap between the cabinet door and the ring block.

[0013] By adopting the above technical solution, the cabinet door can slide along the door tracks opened by the upper ring block and the lower ring block until the cabinet door is in close contact with the two side walls of the cabinet body. At this time, the cabinet door is fully opened and will not block the opening of the cabinet body, making it convenient to move the storage rack out of the cabinet body.

[0014] Optionally, the lower ring block includes a bottom block and a support block, and door rails are provided on the bottom block and the support block; hinges are connected between adjacent support blocks, and when the support blocks are located on the same straight line, the door rails of the bottom block are connected to the door cabinets of the support blocks.

[0015] By adopting the above technical solution, when the maintenance personnel need to move the storage rack out of the cabinet, the user needs to first rotate the support block to misalign the support block with the bottom block, and then slide the storage rack. When the storage rack is moved out of the cabinet, the bottom of the storage rack will be placed on the support block, and the storage rack will be supported by the support block to prevent the entire cabinet from tipping over due to the instability of the storage rack.

[0016] Optionally, a locking block is provided at one end of the support block away from the hinge, and a locking groove for inserting the locking block is provided at one end of the bottom block facing the support block.

[0017] By adopting the above technical solution, when the locking block is inserted into the locking groove, due to the restriction of the locking block, the door rail of the supporting block always remains connected with the door rail of the bottom block, and the supporting block cannot move at will.

[0018] Optionally, the locking block is provided with anti-slip grooves.

[0019] By adopting the above technical solution, the presence of the anti-slip pattern enables maintenance personnel to quickly identify the position of the locking block, while increasing the friction between the hand and the locking block, making it easier to slide the locking block.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Maintenance personnel can hold the handpiece and pull the storage rack as a whole to move the electrical components placed on the storage rack out of the cabinet to facilitate maintenance of the electrical components;

[0022] 2. The cabinet door can be moved to both sides of the cabinet and fit closely to the side wall of the cabinet without affecting the movement of the storage rack.

[0023] 3. A support block is provided at the bottom of the cabinet to support the storage rack that is moved out of the cabinet, so as to prevent the entire cabinet from tipping over due to the forward tilting of the center of gravity of the storage rack. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The present application embodiment discloses a power distribution cabinet that is easy to maintain. Figure 1 , Figure 2 A power distribution cabinet that is easy to maintain includes a cabinet body 1 with an opening and a cabinet door 2. Electrical components are installed inside the cabinet body 1, and the electrical components inside the cabinet body 1 are protected by closing the cabinet door 2.

[0031] Reference Figure 1, Figure 2 A storage rack 3 is also slidably connected in the cabinet 1, and the electrical components are all mounted and installed on the storage rack 3, and the storage rack 3 can be moved out of the cabinet 1 through the opening of the cabinet 1. Cavities 4 are provided on both side walls of the storage rack 3 that contact the cabinet 1. When maintenance personnel repair the electrical components, they can access the electrical components located deep in the storage rack 3 through the cavity 4.

[0032] Reference Figure 2 , Figure 3 , the storage rack 3 is also rotatably connected to the two sides of the cabinet 1, and the rotating rod 5 can rotate in a circle along its own center line, and a movable rod 6 is inserted at the free end of the rotating rod 5, and the movable rod 6 is rotatably connected to the rotating rod 5, and a hand piece 7 is integrally formed at the two ends of the movable rod 6. A hand grip groove 8 for the maintenance personnel to insert their fingers is provided in the hand grip groove 8. When the maintenance personnel need to pull the storage rack 3, they can insert their fingers into the hand grip groove 8 to hold the hand piece 7, so as to facilitate the application of force when pulling the storage rack 3.

[0033] Reference Figure 2 A plurality of groups of balls 11 are rollingly connected to the two inner side walls of the cabinet 1. The balls 11 can fit tightly against the solid part of the storage rack 3. The balls 11 can reduce the friction between the storage rack 3 and the cabinet 1 when the storage rack 3 moves, so that it is convenient for maintenance personnel to pull the storage rack 3.

[0034] Reference Figure 2 , Figure 3 , movable cavities 9 are also provided on both sides of the cabinet 1, and the movable cavity 9 is flush with the handpiece 7 and the handpiece 7 can be inserted into the movable cavity 9. A limit plate 10 integrally generated with the cabinet 1 is also provided at the cavity opening of the movable cavity 9. When the maintenance personnel pull the storage rack 3 out of the cabinet 1 through the handpiece 7 and complete the inspection, the cabinet 1 can be pushed back into the cabinet 1 later. At this time, in order to prevent the storage rack 3 from shaking when it is inside the cabinet 1, the maintenance personnel can rotate the handpiece 7, insert part of the handpiece 7 between the limit plate 10 and the inner cavity wall of the movable cavity 9, and clamp the handpiece 7 through the limit plate 10 and the inner cavity wall of the movable wall, so as to fix the handpiece 7 and limit the handpiece 7 and the movable rod 6, so as to achieve a relatively fixed connection between the storage rack 3 and the cabinet 1.

[0035] Reference Figure 2 , Figure 4An upper ring block 12 and a lower ring block 13 are installed on the outside of the cabinet 1, and the upper ring block 12 and the lower ring block 13 are fixedly connected to the top and the bottom of the cabinet 1 respectively. The cabinet door 2 is slidably connected to the door track 14 opened by the upper ring block 12 and the lower ring block 13. Moving blocks 15 are also integrally formed on the upper and lower sides of the cabinet door 2, and the moving blocks 15 are inserted into the upper ring block 12 or the lower ring block 13 in the corresponding direction. The cabinet door 2 slides in the upper ring block 12 and the lower ring block 13 through the moving blocks 15. And because there is a gap between the cabinet door 2 and the upper ring block and the lower ring block, the cabinet door 2 can also rotate in a circle with the moving block 15 as the reference point. When the maintenance personnel are ready to pull the storage rack 3, they can first push the cabinet door 2, move the two cabinet doors 2 to the two sides of the cabinet 1, and make the cabinet door 2 close to the two side walls of the cabinet 1.

[0036] Reference Figure 2 , Figure 4 The lower ring block 13 is composed of a bottom block 18 and a support block 17, and door gauges are provided on the bottom block 18 and the support block 17. The bottom block 18 is fixedly connected to the outside of the cabinet 1, and a hinge 16 is provided at one end of the two support blocks 17 that are close to each other, and the two support blocks 17 can be rotated through the hinge 16. When the maintenance personnel are ready to pull the storage rack 3, the maintenance personnel can first rotate the two support blocks 17 so that the two support blocks 17 move toward each other and are located at the bottom of the storage rack 3. When the storage rack 3 is moved out of the cabinet 1, the storage rack 3 will be mounted on the support block 17. Supporting the storage rack 3 by the support block 17 improves the stability of the storage rack 3 and reduces the possibility of tipping over due to the shift of the center of gravity of the storage rack 3.

[0037] Reference Figure 2 , Figure 4 , a locking block 19 is slidably connected to the end of the support block 17 away from the hinge 16, and a locking groove 20 for inserting the locking block 19 is provided at the end of the bottom block 18 facing the support block 17. After the storage rack 3 is retracted into the cabinet body 1, the maintenance personnel can fix the support block 17 and the bottom block 18 by the locking block 19. After the two support blocks 17 are rotated in a direction away from each other until they are tightly attached to the cabinet body 1, the locking block 19 is aligned with the locking groove 20 at this time, and the maintenance personnel can fix the support block 17 by pushing the locking block 19 into the locking groove 20. When the locking block 19 is aligned with the locking groove 20, the door rail 14 on the support block 17 is also aligned with the door rail 14 on the bottom block 18, and the subsequent cabinet door 2 can also continue to slide on the lower ring block 13. The locking block 19 is also provided with anti-slip grooves 21 to facilitate maintenance personnel to quickly identify the position of the locking block 19 and increase the friction between the hand and the locking block 19 to facilitate sliding of the locking block 19.

[0038] The embodiment of the present application discloses a distribution cabinet that is easy to maintain. The implementation principle is: when the maintenance personnel need to repair the electrical components located in the cabinet 1, first rotate the handpiece 7 out from between the limit plate 10 and the cabinet 1, then retract the locking block 19 into the support block 17, and rotate the support block 17, and finally hold the handpiece 7 to pull the storage rack 3 out of the cabinet 1 to repair the electrical components located on the storage rack 3.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
