Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage switchgear technology, and in particular to a high-voltage switchgear mounting bracket that is easy to maintain. Background Technology
[0002] As a key piece of equipment in the power system, the incoming line cabinet of the intelligent high-voltage switchgear undertakes important functions such as power reception, distribution, monitoring, control, and protection. In the typical structure of a fixed incoming line cabinet, the instrument room, switch room, and cable room are usually arranged adjacently to optimize electrical connections. Specifically, the instrument room is located at the upper front door of the cabinet, while the switch room is fixedly installed between the instrument room and the cable room. A metal partition fixed with bolts is used to physically isolate the switch room and the cable room. This design has obvious inconveniences during maintenance: firstly, maintenance personnel must remove multiple fixing bolts to remove the partition; secondly, there is no dedicated temporary storage location for the removed partition and the circuit breakers installed on it, which not only increases the difficulty of operation but may also affect maintenance efficiency. This design deficiency restricts the maintainability of the equipment to a certain extent. Therefore, there is an urgent need for a device with a quick-disassembly structure that can also provide temporary support. Utility Model Content
[0003] To overcome the shortcomings of the existing problems mentioned above, this utility model provides a high-voltage switchgear mounting bracket that is easy to maintain.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-voltage switchgear mounting bracket for easy maintenance, including a cabinet, a mounting plate, and a linkage plate. The mounting plate has multiple arrayed through holes that penetrate the mounting plate. The mounting plate and the linkage plate are rotatably connected by a first rotating shaft. A second rotating shaft is provided on the side of the linkage plate away from the first rotating shaft. The linkage plate is rotatably connected to the inner wall of the cabinet through the second rotating shaft. The shaft and bushing of the second rotating shaft cannot be axially pulled out. In use, if the linkage plate is not provided, the mounting plate is directly connected to the inner wall of the cabinet by the rotating shaft. After opening the outer cabinet door of the incoming line cabinet, the mounting plate is obstructed and cannot be fully opened. Furthermore, components such as circuit breakers on the mounting plate will be blocked, making maintenance inconvenient. It can assist in fully opening the mounting plate without affecting the operator's inspection and maintenance of the rear cable compartment; the linkage plate in the closed state is attached to the inner wall of the cabinet, and a ring of limiting members is set inside the cabinet. The limiting members are located behind the mounting plate in the closed state. The limiting members can restrict the position of the mounting plate and prevent the first rotating axis from rotating to the cable compartment side; a buckle post is set at the end of the limiting member away from the linkage plate. The diameter of the head of the buckle post is larger than the diameter of the post body. An elongated oval buckle connected to the first rotating axis is set on the side of the mounting plate away from the mounting plate. A semi-circular concave hole is set on the side of the buckle away from the mounting plate. The concave hole on the buckle can engage with the post body. Rotating the buckle can fix and open the mounting plate without removing the bolts.
[0005] Preferably, the through hole is gourd-shaped with a larger top and a smaller bottom. It can be equipped with a fast-fitting component or a regular component, which can be fixed to the mounting plate by passing through the through hole with bolts or other fixing methods.
[0006] Preferably, the first rotating shaft includes a shaft body and a bushing. The shaft body is fixedly installed on the side of the mounting plate, and the bushing is fixedly installed on the side of the linkage plate. The lower end of the shaft body is provided with an assembly section with a reduced diameter. The bushing is a hollow cylindrical structure. The assembly section can be inserted into the bushing. The inner wall of the bushing and the outer wall of the assembly section form a sliding fit, so that the shaft body can rotate relative to the bushing. The two can be separated by axial movement. When necessary, the first rotating shaft can be pulled upward, and the mounting plate can be removed from the top.
[0007] The beneficial effects of this utility model are as follows: It improves the structure of the partition between the switch compartment and the cable compartment, changing it from a fixed structure to an openable structure. The two-stage opening method avoids the problem of the mounting plate being restricted by components such as circuit breakers and the incoming line cabinet door, preventing it from being fully opened. While the mounting plate can be fully opened, the rotating shaft remains connected to the cabinet, solving the problem of where to place the partition after removal. The method of fixing the partition with bolts has been eliminated, replaced by a snap-fit connection, simplifying the operation process and reducing maintenance time. While improving the structure, the function of removing the entire mounting plate is still retained, allowing for complete disassembly when necessary. The mounting plate is equipped with regularly arranged gourd-shaped through holes, allowing for quick installation of required components, or bolt fastening, providing diverse options for maintenance work.

[0014] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0016] like Figure 1-4 The high-voltage switchgear mounting bracket shown includes a cabinet 1, a mounting plate 2, and a linkage plate 3. The mounting plate 2 has multiple arrayed through holes 4 that penetrate the mounting plate 2. The mounting plate 2 and the linkage plate 3 are rotatably connected by a first rotating shaft 5. A second rotating shaft 6 is provided on the side of the linkage plate 3 away from the first rotating shaft 5. The linkage plate 3 is rotatably connected to the inner wall of the cabinet 1 via the second rotating shaft 6. The shaft and bushing of the second rotating shaft 6 cannot be axially pulled out. In use, if the linkage plate 3 is not provided, the mounting plate 2 is directly connected to the inner wall of the cabinet by the rotating shaft. After opening the outer cabinet door of the incoming line cabinet, the mounting plate 2 is obstructed and cannot be fully opened. Furthermore, components such as circuit breakers on the mounting plate 2 will be blocked, making maintenance inconvenient. The linkage plate 3 can assist the mounting plate 2 in fully opening. This does not affect the operator's inspection and maintenance of the rear cable compartment; the linkage plate 3 in the closed state is attached to the inner wall of the cabinet 1, and a ring of limiting members 7 is provided inside the cabinet 1. The limiting members 7 are located behind the mounting plate 2 in the closed state. The limiting members 7 can restrict the position of the mounting plate 2 and prevent the first rotating shaft 5 from rotating towards the cable compartment; a buckle post 8 is provided at the end of the limiting member 7 away from the linkage plate 3. The diameter of the head of the buckle post 8 is larger than the diameter of the post body. An oblong buckle 9 connected by the rotating shaft is provided on the side of the mounting plate 2 away from the first rotating shaft 5. A semi-circular concave hole 10 is provided on the side of the buckle 9 away from the mounting plate. The concave hole 10 on the buckle 9 can be engaged with the post body of the buckle post 8. Rotating the buckle 9 can fix and open the mounting plate 2 without removing the bolts.
[0017] The through hole 4 is gourd-shaped with a larger top and a smaller bottom. It can be equipped with components that can be quickly snapped on, or ordinary components can be used and fixed to the mounting plate 2 by bolts or other fixing methods through the through hole.
[0018] The first rotating shaft 5 includes a shaft body 5.1 and a bushing 5.2. The shaft body 5.1 is fixedly installed on the side of the mounting plate 2, and the bushing is fixedly installed on the side of the linkage plate 3. The lower end of the shaft body 5.1 is provided with an assembly section 5.3 with a reduced diameter. The bushing 5.2 is a hollow cylindrical structure. The assembly section 5.3 can be inserted into the bushing 5.2. The inner wall of the bushing 5.2 and the outer wall of the assembly section 5.3 form a sliding fit, so that the shaft body 5.1 can rotate relative to the bushing 5.2, and the two can be separated by axial movement. When necessary, the shaft body 5.1 of the first rotating shaft 5 can be pulled upward, and the mounting plate 2 can be removed from the top. Specific Implementation
[0019] After safely opening the outer cabinet door of cabinet 1, the operator, under the premise of ensuring safety, rotates the buckle 9 upwards. The buckle 9 separates from the buckle post 8. After separation, first rotate the mounting plate 2 towards the operator's side at a certain angle. After the mounting plate 2 is exposed from inside the cabinet 1, pull the mounting plate 2 away from the linkage plate 3. At this time, the linkage plate 3 also rotates at a certain angle. Then rotate the mounting plate 2 and the linkage plate 3 together towards the operator's side. After rotating to a certain angle, the linkage plate 3 abuts against the cabinet door side of cabinet 1. Continue to rotate the mounting plate 2 to open the entire mounting frame, fully exposing the cable compartment on the rear side of the switch room. After the operation is completed, the above operation is repeated in reverse when the mounting frame needs to be closed again. When the mounting plate 2 touches the limit piece 7, it is closed in place. At this time, rotate the buckle 9 downwards to lock it onto the column part of the buckle post 8, and the mounting frame can be fixed back inside the cabinet.
[0020] This ingenious design eliminates the traditional bolt-fixed partition method, replacing it with a snap-fit system, simplifying the operation, reducing bolt removal time, and minimizing subsequent maintenance time. The rotating linkage between the mounting plate and the linkage plate avoids the problem of the internal mounting plate being unable to fully open due to the external cabinet door. Furthermore, the first pivot is a non-fixed, detachable design, retaining the ability to remove the entire mounting plate. The regularly arranged gourd-shaped through holes on the mounting plate allow for quick-attachment of components or fastening with bolts. This design not only improves maintenance efficiency but also provides diverse options for maintenance work, considering various possibilities for operators.
[0021] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
