Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a high and low voltage switch cabinet which is convenient for maintenance. Background Art

[0002] As the name suggests, high and low voltage switchgear is a device that connects high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various power users. The equipment inside is nothing more than some protective devices such as switches and circuit breakers assembled into one.

[0003] High and low voltage switchgear is a device used to connect high-voltage or low-voltage cables. Currently, high and low voltage switchgear are the core of power transmission hubs when they are put into use. Therefore, in order to ensure the normal operation of high and low voltage switchgear, regular and irregular maintenance and inspection are required. However, common cabinets are all integrated, resulting in the staff having to extend their bodies into the cabinet to operate during the inspection or maintenance process, and the operating space is limited, which is not convenient for inspection and maintenance. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high and low voltage switch cabinet that is easy to maintain. The utility model provides a larger working platform and space for maintenance personnel by turning the plate from a vertical state to a horizontal state, which is convenient for placing and taking maintenance tools, greatly improving the convenience of maintenance work, and facilitating the maintenance of internal components of the switch cabinet by opening and closing the closing plate.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high and low voltage switchgear that is easy to maintain, comprising a switchgear main body:

[0007] Two through holes are provided on both sides of the switch cabinet body, a sliding cavity is provided inside the through hole, a closing plate is slidably connected to the interior of the sliding cavity, the closing plate and the sliding cavity are elastically connected via two second springs, and a limiting mechanism for fixing the closing plate is provided on the inner bottom of the sliding cavity;

[0008] The interior of the through hole is rotatably connected to a rotating plate, and the upper end of the rotating plate is provided with a fixing mechanism for limiting and fixing with the closing plate.

[0009] Preferably, a hand-pull groove is provided on the side wall of the closing plate for pulling the closing plate.

[0010] Preferably, the limiting mechanism includes a sliding hole opened on the bottom of the sliding cavity, a latch is slidably connected inside the sliding hole, an opening connected to the sliding hole is opened on the side wall of the switch cabinet body, a toggle block is slidably connected inside the opening and is fixedly connected to the latch, and the latch and the sliding hole are elastically connected by a third spring.

[0011] Preferably, a socket adapted to fit the latch is provided at the lower end of the closing plate.

[0012] Preferably, the fixing mechanism includes an L-shaped groove opened on the upper end of the rotating plate, and a card block is slidably connected inside the L-shaped groove. The card block and the L-shaped groove are elastically connected by two first springs, and a card slot adapted to the card block is opened at the lower end of the closing plate.

[0013] Preferably, the lower end of the clamping block has an inclined surface on the side facing the closing plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. By simply pulling the card block, the restriction on the rotating plate can be released, and it can be transformed from a vertical state to a horizontal state. This conversion process is fast and easy to operate, providing maintenance personnel with a larger working platform and space, making it easier to place and access maintenance tools, greatly improving the convenience of maintenance work;

[0016] 2. The design of the closing plate also reflects convenience. Its extension and retraction can be easily controlled by hand-pulling the groove, and automatic locking and unlocking are achieved in conjunction with the latch, reducing the steps of manual fixing and unlocking and improving work efficiency. The automatic locking mechanism of the latch and the socket ensures that the closing plate can firmly close the through-hole when needed, preventing accidental opening or loosening, and further ensuring the safety of equipment and maintenance personnel.

Therefore, they cannot be understood as limitations on the present invention.

[0023] Reference Figure 1-Figure 3 A high and low voltage switchgear that is easy to maintain, including a switchgear body 1:

[0024] Two through holes 5 are provided on both sides of the switch cabinet body 1, and a sliding cavity 11 is provided on the inner side of the through hole 5. A closing plate 9 is slidably connected to the inside of the sliding cavity 11. A hand-pulled groove is provided on the side wall of the closing plate 9 for pulling the closing plate 9. The closing plate 9 and the sliding cavity 11 are elastically connected by two second springs 10. The inner bottom of the sliding cavity 11 is provided with a limiting mechanism for fixing the closing plate 9. The limiting mechanism includes a sliding hole 15 provided on the inner bottom of the sliding cavity 11. A latch 14 is slidably connected to the inside of the sliding hole 15. An opening 3 connected to the sliding hole 15 is provided on the side wall of the switch cabinet body 1. A toggle block 2 is slidably connected to the inside of the opening 3 and is fixedly connected to the latch 14. The latch 14 and the sliding hole 15 are elastically connected by a third spring 13. The lower end of the closing plate 9 is provided with a socket adapted to the latch 14;

[0025] The through hole 5 is internally rotatably connected to a rotating plate 4, and the upper end of the rotating plate 4 is provided with a fixing mechanism for restricting and fixing with the closing plate 9. The fixing mechanism includes an L-shaped groove 7 opened at the upper end of the rotating plate 4, and the L-shaped groove 7 is internally slidably connected to a clamping block 6. The clamping block 6 and the L-shaped groove 7 are elastically connected by two first springs 8. The lower end of the closing plate 9 is provided with a clamping groove 12 adapted to the clamping block 6, and the lower end of the clamping block 6 is inclined toward the side of the closing plate 9.

[0026] Working principle:

[0027] During maintenance, by pulling the block 6 downward, the first spring 8 is in a compressed state, the block 6 is disengaged from the slot 12, and the restriction of the rotating plate 4 is released, so that the rotating plate 4 can be in a horizontal state. The rotating plate 4 in a horizontal state can be used to place maintenance tools, which is convenient for maintenance personnel;

[0028] Subsequently, the closing plate 9 is pulled into the sliding cavity 11 by hand-pulling the groove. When the insertion hole is aligned with the latch 14, the latch 14 is ejected by the action of the third spring 13 and inserted into the insertion hole, thereby achieving the purpose of restricting and fixing.

[0029] After the inspection is completed, the toggle block 2 can be pulled to disengage the latch 14 from the socket, thereby releasing the restriction on the closing plate 9 . Under the action of the second spring 10 , the closing plate 9 pops out to close the through hole 5 .

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
