Description

Technical Field

[0001] The present application relates to the technical field of switch cabinets, and in particular to a switch cabinet that can be quickly grounded. Background Art

[0002] A switch cabinet is an electrical device used for power generation, transmission, distribution, and power conversion in a power system. Its main functions are to switch, control, and protect electrical equipment. During daily use, the switch cabinet needs to be regularly maintained. During the maintenance process, the staff needs to first connect a ground wire to the switch cabinet to ensure the safety of the maintenance personnel.

[0003] In the related art, the switch cabinet includes a cabinet body, a placement groove is provided on the cabinet body, and a grounding head is provided in the placement groove.

[0004] The staff needs to install the plug at the grounding head. However, due to the relatively long length of the plug itself, the plug will protrude from the placement groove during the installation process. There is a risk that the staff may accidentally touch the plug while walking. Summary of the Invention

[0005] In order to improve the problem that the plug protrudes from the placement groove, the present application provides a switch cabinet that can be quickly grounded.

[0006] A switch cabinet that can be quickly grounded provided by the present application adopts the following technical solutions:

[0007] A switch cabinet that can be quickly grounded includes a cabinet body, a placement groove is provided on the cabinet body, a grounding head is provided in the placement groove, a transfer piece is provided on the grounding head, the transfer piece extends in the vertical direction, and the transfer piece is used for connecting the plug; when the plug is installed on the transfer piece, the plug can be located within the placement groove.

[0008] By adopting the above technical solutions, the transfer piece is arranged in the placement groove and extends in the vertical direction, so that the plug can be located within the placement groove, reducing the risk of accidental touch due to the plug protruding from the placement groove, and making the switch cabinet safer when grounding.

[0009] Optionally, an insulating plate is rotatably connected to the cabinet body, and the insulating plate is used to shield the placement groove.

[0010] By adopting the above technical solutions, the staff installs the plug on the grounding head, and then rotates the insulating plate to shield the placement groove, so that the staff is not likely to accidentally touch the grounding head during the maintenance process; and the insulating plate has an insulating function, so that the staff will not be damaged due to accidentally touching the insulating plate, increasing the safety of the staff.

[0011] Optionally, a stop groove is formed in the cabinet body, a stop bar for inserting into the stop groove is provided on the insulating board, a card slot communicating with the stop groove is formed in the cabinet body, a card strip is slidably connected in the card slot, and a card hole for inserting the card strip is formed in the stop bar. When the card strip is inserted into the card hole, the stop bar is located in the stop groove.

[0012] By adopting the above technical solution, the staff slides the card strip to insert the card strip into the card hole, so that the card strip limits the stop bar. At this time, the stop bar is located in the stop groove, enabling the stop bar and the card strip to be fixed to each other, so that the cabinet body and the insulating board can be fixed to each other, reducing the possibility of the insulating board rotating on the cabinet body, enabling the insulating board to stably block the placement groove, and further reducing the risk of the staff accidentally touching the grounding head.

[0013] Optionally, a moving spring is provided in the card slot, the moving spring drives the card strip to insert into the card hole, an operation hole communicating with the card slot is formed in the cabinet body, an operation strip is slidably connected in the operation hole, and an operation inclined surface is formed on the operation strip, and the operation inclined surface is used to drive the card strip to disengage from the card hole; when the operation strip protrudes from the cabinet body, the card strip is inserted into the card hole.

[0014] By adopting the above technical solution, the staff slides the operation strip to make the operation strip located in the operation hole. The operation strip pushes the card strip to move through the operation inclined surface, so that the card strip disengages from the card hole, enabling the card strip not to limit the limiting strip and realizing the unlocking of the insulating board and the cabinet body; the moving spring drives the card strip to move, so that the card strip is inserted into the card hole, and the card strip is not easy to slide in the card hole, enabling the card strip and the stop bar to be fixed to each other and reducing the possibility of separation between the card strip and the stop bar; at the same time, the staff can directly insert the stop bar into the stop groove and let the moving spring drive the card strip to move to realize the automatic locking of the insulating board.

[0015] Optionally, a receiving groove for placing electrical components is formed in the cabinet body, and a receiving board is rotatably connected to the receiving groove; when the receiving board and the insulating board are closed, the receiving board is located on the side of the insulating board facing the bottom wall of the placement groove.

[0016] By adopting the above technical solution, since the receiving board is rotatably connected to the receiving groove and the receiving board is located on the side of the insulating board facing the bottom wall of the placement groove, the staff needs to open the insulating board first and then open the receiving board, avoiding accidents caused by the staff forgetting to connect the grounding head, and further enhancing the safety ability of the staff to repair the switch cabinet.

[0017] Optionally, a through hole for inserting the operation strip is formed in the receiving board, a limiting spring is provided in the through hole, a limiting block is provided on the limiting spring, and a limiting groove for inserting the limiting block is formed on the operation strip. When the limiting block is inserted into the limiting groove, the receiving board blocks the receiving groove.

[0018] By adopting the above technical solution, the staff closes the receiving plate and makes the receiving plate abut against the cabinet body. At this time, the operating bar is located in the through hole. The limiting spring drives the limiting block to move, so that the limiting block is inserted into the limiting groove, enabling the limiting block to restrict the operating bar and allowing the limiting block and the operating bar to be fixed to each other, thereby enabling the receiving plate to be fixed to the cabinet body and reducing the possibility of the receiving plate rotating on the cabinet body.

[0019] Optionally, a connecting bar is slidably connected in the through hole, and an arc surface is formed on the limiting block; when the connecting bar is completely located in the through hole, the operating bar drives the clamping bar to disengage from the clamping hole.

[0020] By adopting the above technical solution, by sliding the connecting bar to make the connecting bar completely located in the through hole, the connecting bar is made to push the operating bar to move. Since the arc surface is provided on the limiting block, the limiting block can be disengaged from the limiting groove, so that the operating bar can be disengaged from the through hole, the limiting block does not restrict the receiving plate, and the receiving plate can rotate on the cabinet body, enabling the staff to repair the electrical components in the receiving groove; at the same time, the operating bar drives the clamping bar to disengage from the clamping hole, so that the clamping bar does not limit the stopping bar, and the stopping bar can be taken out of the stopping groove, unlocking the insulating plate.

[0021] Optionally, a rotating block is rotatably connected to the insulating plate. The rotating block is provided with a first magnet and a second magnet, and the connecting bar is provided with a third magnet. The first magnet is used to adsorb the third magnet, and the second magnet is used to repel the third magnet; when the first magnet adsorbs the third magnet, the connecting bar is not completely located in the through hole; when the second magnet repels the third magnet, the connecting bar is completely located in the through hole.

[0022] By adopting the above technical solution, the staff rotates the rotating block to make the first magnet adsorb the third magnet, so that the connecting bar moves in the direction of the rotating block, and the connecting bar is not completely inserted into the through hole, so that the connecting bar does not drive the operating bar to slide in the through hole; the staff rotates the rotating block to make the second magnet repel the third magnet, so that the connecting bar moves in the direction of the operating bar. At this time, the connecting bar is completely located in the through hole, so that the connecting bar can drive the operating bar to disengage from the through hole, unlocking the receiving plate and the cabinet body. At this time, the operating bar disengages from the clamping hole through the clamping bar, unlocking the insulating plate and the cabinet body, facilitating the staff to rotate the insulating plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging the adapter piece in the placement groove and the adapter piece extending in the vertical direction, the plug can be located in the placement groove, reducing the risk of the plug protruding from the placement groove and being accidentally touched, making the switch cabinet safer when grounding.

[0025] 2. The staff slides the operation bar so that the operation bar is located within the operation hole. The operation bar pushes the clamping bar to move through the operation inclined surface, causing the clamping bar to disengage from the clamping hole, so that the clamping bar does not limit the limiting bar, realizing the unlocking of the insulating board and the cabinet body; the clamping bar is driven to move by the moving spring, causing the clamping bar to insert into the clamping hole. The clamping bar is not likely to slide within the clamping hole, so that the clamping bar and the stopping bar can be fixed to each other, reducing the possibility of separation between the clamping bar and the stopping bar; at the same time, the staff can directly insert the stopping bar into the stopping groove, and the moving spring drives the clamping bar to move, realizing the automatic locking of the insulating board.

A placement groove 11 is provided on the cabinet body 1. A plurality of grounding heads 12 are fixedly connected in the placement groove 11, and the grounding heads 12 extend in a direction away from the bottom wall of the placement groove 11.

[0037] Refer to Figure 2 , a transfer piece 13 is provided on the surface of the grounding head 12, and the transfer piece 13 extends in the vertical direction. The transfer piece 13 includes a mounting portion 131 and a connecting portion 132. The mounting portion 131 is integrally formed on the connecting portion 132. The mounting portion 131 is installed and fixed to the grounding head 12, and the connecting portion 132 is connected to the plug. The connecting portion 132 is bent in a direction away from the bottom wall of the placement groove 11 to facilitate the insertion of the plug.

[0038] Refer to Figure 2 , a plurality of fasteners 14 are provided on the transfer piece 13, and the fasteners 14 fix the grounding head 12 and the transfer piece 13 to each other. The fasteners 14 include a fastening bolt 141 and a fastening nut 142. The fastening bolt 141 passes through the grounding head 12 and the transfer piece 13 and is threadedly connected to the fastening nut 142 to fix the grounding head 12 and the transfer piece 13.

[0039] Refer to Figure 1 and Figure 2 , an insulating plate 2 is rotatably connected to the cabinet body 1. The insulating plate 2 is made of glass, and the staff can directly observe the inside of the placement groove 11 through the insulating plate 2. The insulating plate 2 can block the opening of the placement groove 11. A connection hole 21 is provided on the surface of the insulating plate 2 for the wire of the plug to pass through.

[0040] The implementation principle of Embodiment 1 is as follows: The staff opens the insulating plate 2, connects the plug to the connecting portion 132, and then closes the insulating plate 2 to achieve the grounding treatment of the switch cabinet.

[0041] Embodiment 2

[0042] Refer to Figure 3 and Figure 4, the difference between this embodiment and Embodiment 1 is that a receiving groove 15 is formed on the cabinet body 1, and electrical components are placed in the receiving groove 15. A receiving plate 3 is rotatably connected to the cabinet body 1, and the receiving plate 3 is used to block the opening of the receiving groove 15. When the receiving plate 3 blocks the opening of the receiving groove 15, the receiving plate 3 is in a closed state. When the insulating plate 2 blocks the opening of the placement groove 11, the insulating plate 2 is in a closed state. When both the insulating plate 2 and the receiving plate 3 are in the closed state, the insulating plate 2 is located on the side of the receiving plate 3 facing the bottom wall of the placement groove 11.

[0043] Referring to Figure 5 , a stop bar 22 is fixedly connected to the surface of the insulating plate 2, and a stop groove 16 for inserting the stop bar 22 is formed on the surface of the cabinet body 1 where the receiving groove 15 is formed. A clamping groove 17 is formed on the groove wall of the stop groove 16, a moving spring 171 is fixedly connected to the bottom wall of the clamping groove 17, a clamping bar 172 is fixedly connected to the surface of the moving spring 171 away from the bottom wall of the clamping groove 17, and a clamping hole 221 for inserting the clamping bar 172 is formed on the surface of the stop bar 22. The moving spring 171 drives the clamping bar 172 to insert into the clamping hole 221, that is, when the clamping bar 172 is located in the clamping hole 221, the moving spring 171 is in a non-loaded state; when the clamping bar 172 is located in the clamping groove 17, the moving spring 171 is in a compressed state. When the clamping bar 172 is inserted into the clamping hole 221, the stop bar 22 is located in the stop groove 16, and at this time the insulating plate 2 is in a closed state.

[0044] Referring to Figure 4 , Figure 5 and Figure 6 , an operation hole 18 communicating with the clamping groove 17 is formed on the surface of the cabinet body 1 where the receiving groove 15 is formed, and an operation bar 181 is slidably connected in the operation hole 18.

[0045] Referring to Figure 6 and Figure 7 , an operation inclined surface 182 is formed on the surface of the operation bar 181 facing the clamping groove 17, and the distance between the operation inclined surface 182 and the stop groove 16 gradually decreases along the direction from the receiving plate 3 to the cabinet body 1.

[0046] Referring to Figure 6 and Figure 7 , a stop block 222 is fixedly connected to the surface of the clamping bar 172, and the stop block 222 is located on the sliding path of the operation bar 181. When the operation bar 181 is inserted into the operation hole 18, the operation bar 181 drives the stop block 222 to move through the operation inclined surface 182, so that the clamping bar 172 is disengaged from the stop groove 16.

[0047] Referring to Figure 6 and Figure 7, a perforation 31 is formed on the surface of the accommodation plate 3, and the operating bar 181 is inserted into the perforation 31. A groove 32 is formed on the pore wall of the perforation 31, and a limiting spring 321 is arranged on the groove 32. One end of the limiting spring 321 is fixedly connected to the bottom wall of the groove 32, and the other end of the limiting spring 321 is fixedly connected with a limiting block 322. A limiting groove 183 for inserting the limiting block 322 is formed on the outer surface of the operating bar 181. When the limiting block 322 is inserted into the limiting groove 183, the operating bar 181 is fixed in the perforation 31, and at this time, the operating bar 181 cannot drive the stop block 222 to move.

[0048] Refer to Figure 6 and Figure 7 , an arc surface is formed on the surface of the limiting block 322 away from the limiting spring 321, and a connecting bar 311 is slidably connected in the perforation 31, and the connecting bar 311 slides along the length direction of the perforation 31. When the staff pushes the connecting bar 311, the limiting block 322 disengages from the limiting groove 183 through the arc surface, so that the operating bar 181 can be inserted into the operating hole 18.

[0049] Refer to Figure 6 and Figure 7 , when the connecting bar 311 is completely located in the perforation 31, the connecting bar 311 pushes the operating bar 181 to move. At this time, the limiting block 322 disengages from the limiting groove 183 through the arc surface, so that the operating bar 181 can push the stop block 222 to move.

[0050] Refer to Figure 6 , a rotating groove 23 for inserting the connecting bar 311 is formed on the insulating plate 2, and a rotating block 231 is rotatably connected to the surface of the insulating plate 2. A first magnetic attraction groove 232 and a second magnetic attraction groove 233 are formed on the surface of the rotating block 231 facing the connecting bar 311. A first magnet 234 is fixedly connected in the first magnetic attraction groove 232, and a second magnet 235 is fixedly connected in the second magnetic attraction groove 233. A third magnet 312 is fixedly connected to the surface of the connecting bar 311 facing the rotating block 231. The first magnet 234 attracts the third magnet 312, and the second magnet 235 repels the third magnet 312.

[0051] Refer to Figure 6 , when the first magnet 234 corresponds to the third magnet 312, the first magnet 234 attracts the third magnet 312, and the connecting bar 311 is partially located in the rotating groove 23. At this time, the connecting bar 311 will not drive the operating bar 181 to move. When the second magnet 235 corresponds to the third magnet 312, the second magnet 235 repels the third magnet 312, and the connecting bar 311 is completely located in the perforation 31, so that the connecting bar 311 pushes the operating bar 181 to move.

[0052] The implementation principle of Embodiment 2 is as follows: First, the staff rotates the rotating block 231 to align the second magnet 235 with the third magnet 312, and makes the connecting bar 311 completely located within the through hole 31. At this time, the connecting bar 311 pushes the operating bar 181 to move, and the operating bar 181 pushes the clamping bar 172 to move through the operating inclined surface 182, so that the stop bar 22 disengages from the stop groove 16, realizing the unlocking of the insulating plate 2.
