[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figures 1 to 4 As shown, this utility model discloses a busbar trunking for a power distribution cabinet, comprising a main body 1 and a top cover assembly 2. The top of the main body 1 is connected to the bottom of the top cover assembly 2. A set of fixing blocks 3 are respectively connected to the left and right ends of the top of the top cover assembly 2. The slot on the front side of one end of the fixing block 3 is slidably engaged with the first locking block 4. The left and right ends of the mounting plate 10 are respectively connected to the other ends of the first locking block 4. The bottom of the annular plate 5 is tightly attached to the top of the top cover assembly 2, and a filter plate 6 is connected to its inner side. Through the setting of the filter plate, dust and impurities in the air can be effectively filtered to prevent them from entering the busbar trunking, thereby improving the dustproof effect and enhancing its practicality.
[0023] The two sets of positioning screws 15 of the positioning component pass through the threaded holes at the rear end of the first locking block 4 and the fixing block 3 respectively and are threadedly connected to them. By rotating the rotating handle 21, the positioning screws 15 are rotated, which can firmly fix the first locking block 4 on the fixing block 3, thereby stabilizing the installation of the filter plate 6. This makes the filter plate installation process simple and convenient, and the positioning is accurate. It can effectively prevent the filter plate from shaking or shifting during the operation of the busbar trunking, ensuring the stability of dust filtration, protecting the clean environment inside the busbar trunking, and thus improving the reliability and safety of the busbar trunking operation, thereby enhancing its practicality.
[0024] Regarding the cleaning mechanism, the mounting blocks 7 at the top of the left and right ends of the main body 1 are provided with sliding grooves. The first slider 8 slides in the sliding grooves and its top is connected to the connecting block 9. The mounting plate 10 is connected to the top of the connecting block 9 through the connecting assembly. The connecting screw 18 in the connecting assembly passes through the threaded hole on the second locking block and the connecting block 9. Rotating the rotating handle 21 can realize the installation and removal of the mounting plate 10. This not only facilitates the assembly of the various parts of the cleaning mechanism, but also allows for quick disassembly when maintenance or replacement of parts is required, greatly improving maintenance efficiency, reducing the downtime of the busbar trunking due to maintenance, and lowering maintenance costs, thus enhancing practicality.
[0025] The bottom of the mounting plate 10 is connected to the support block 11. The groove of the support block 11 is slidably fitted with the top of the pressure block through the buffer assembly. The multiple damping rods 16 and connecting springs 17 in the buffer assembly can effectively reduce vibration during cleaning and keep the cleaning brush 14 in close contact with the filter plate. The buffer assembly plays a good role in protecting the precision components inside the busbar trunking, preventing the vibration generated by the friction between the cleaning brush and the filter plate during the cleaning process from being transmitted into the busbar trunking, preventing damage to components such as conductive bars and insulating materials, extending the service life of the busbar trunking, and keeping the cleaning brush in close contact with the filter plate at all times, thus enhancing its practicality.
[0026] The bottom of the pressure block is connected to the connecting plate 13, and a cleaning brush 14 is installed at the bottom of the connecting plate 13. The cleaning brush 14 slides and adheres tightly to the top of the filter plate 6. Pushing the push plate 19, the mounting plate 10 drives the cleaning brush 14 to slide on the top of the filter plate 6, thereby cleaning the filter plate 6. It can easily clean the dust and impurities accumulated on the surface of the filter plate. The cleaning process is efficient and convenient, without complicated tools and operating procedures, which improves the cleaning efficiency and ensures that the filter plate always maintains good filtration performance, thereby maintaining the cleanliness inside the busbar and ensuring the stability of power transmission, thus enhancing its practicality.
[0027] When it is necessary to disassemble the annular plate 5 for maintenance or replace the filter plate 6, the annular plate 5 can be removed from the busbar trunking cover assembly 2 by pulling the handle 20. The handle design makes the disassembly of the annular plate easy and convenient, allowing staff to inspect, repair or replace the annular plate and filter plate, improving the convenience of busbar trunking maintenance, helping to detect and solve potential problems in a timely manner, ensuring the normal operation of the busbar trunking, and thus enhancing its practicality.
[0028] This utility model discloses a busbar trunking for a power distribution cabinet. During operation, the filter plate 6 is first installed by placing the annular plate 5 and the filter plate 6 on top of the upper cover assembly 2, aligning and engaging the first locking block 4 with the locking groove of the fixing block 3. Then, the rotating handle 21 is rotated, and the first locking block 4 is fixed to the fixing block 3 via the positioning screw 15, completing the installation of the filter plate 6. During the operation of the busbar trunking, the filter plate 6 filters the air entering the busbar trunking, preventing dust and impurities from entering the interior. When cleaning the filter plate 6 is required, the push plate 19 is pushed, and the mounting plate 10 drives the cleaning mechanism. The cleaning brush 14 slides on top of the filter plate 6 to clean dust. During the cleaning process, the brush is kept in close contact with the filter plate by the extension and retraction of multiple damping rods 16 and connecting springs 17. If maintenance or replacement of parts is required for the cleaning mechanism, turn the rotating handle 21 and loosen the connecting screw 18 to disassemble the mounting plate 10 and related parts for repair or replacement. When the annular plate 5 or filter plate 6 needs to be replaced, pull the handle 20 to remove the annular plate 5 for operation. Before completing the above actions, first move it to the position required by the user.

[0030] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
