Description

Technical Field

[0001] This utility model relates to the field of building electrical engineering technology, and more specifically, to a building electrical dust removal device. Background Technology

[0002] Building electrical systems refer to the electrical platforms constructed within buildings using modern advanced scientific theories and electrical technologies. These electrical devices are generally connected to distribution boxes and are centrally managed by the distribution boxes. Due to the large amount of dust generated during construction, dust can enter the equipment through its heat dissipation channels, easily affecting the heat dissipation effect. Therefore, building electrical systems require dust removal structures during use.

[0003] Existing publication number CN220042781U discloses a building electrical dust removal device, including a housing, a mounting groove on the top of a second partition, a filter cartridge installed inside the mounting groove, a cleaning mechanism on the outside of the filter cartridge, and a fixing mechanism on the top of the filter cartridge. An exhaust fan passes through the interior of the first partition, electrical equipment is installed inside the working chamber, and an exhaust fan is installed on the top of the working chamber. The filter cartridge filters dust, the cleaning mechanism cleans the filter cartridge, and the fixing mechanism facilitates quick installation and removal of the filter cartridge. The exhaust fan draws filtered air into the working chamber, and the exhaust fan exhausts air from the working chamber, thus creating air circulation for ventilation and heat dissipation. This structure effectively prevents the dust filter from becoming covered in dust after prolonged use, which could affect heat dissipation and cause equipment malfunction. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When in use, the device uses a brush on a rotating rod to clean the dust adhering to the surface of the filter cartridge. However, over time, the brush on the rotating rod may become damaged or curled due to contact with the filter cartridge, causing it to detach from the filter cartridge surface and thus affecting the cleaning effect of the brush on the rotating rod on the surface of the filter cartridge. Therefore, the rotating rod and brush need to be replaced regularly. However, the rotating rod is fixedly connected to the driven gear, which makes it inconvenient to disassemble and replace the rotating rod and brush.

[0005] Therefore, a building electrical dust removal device is proposed to address the above problems. Utility Model Content

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, a first partition 2 is fixedly installed inside the filter housing 1, and an annular connecting seat 3 is rotatably connected to the first partition 2. Next, a tooth 4 is fixedly installed on the outer wall of the annular connecting seat 3, and a drive gear 5 that meshes with the tooth 4 is rotatably connected to the upper surface of the first partition 2. Finally, a drive motor that drives the drive gear 5 is bolted to the bottom wall of the first partition 2. When adjusting the rotation of the annular connecting seat 3 and the connecting ring 6 installed on the annular connecting seat 3, the drive gear 5 can be driven to rotate first by the drive motor, and then the annular connecting seat 3 and the connecting ring 6 can be driven to rotate by the meshing between the rotating drive gear 5 and the tooth 4.

[0028] In a preferred embodiment, the annular connecting seat 3 is provided with a connecting ring 6 at its upper limit, a filter cylinder is fixedly provided on the bottom wall of the connecting ring 6, and several locking blocks 8 are fixedly provided at the bottom end of the connecting ring 6. The annular connecting seat 3 is provided with several locking grooves 7 that are inserted and connected to the locking blocks 8. The upper surface of the first partition plate 2 is provided with a limiting component for limiting the connecting ring 6. The limiting component includes an annular groove 9, a connecting cylinder 10, a threaded rod 11, a limiting strip 12, a connecting plate 13, a connecting post 14, and a ball bearing 15. The connecting cylinder 10 rotates on the upper surface of the first partition plate 2. The threaded rod 11 is rotatably connected inside the connecting cylinder 10. The connecting plate 13 is threadedly connected to the outside of the threaded rod 11. Two limiting strips 12 are symmetrically provided at the bottom end of the connecting plate 13. The two limiting strips 12 are connected to the connecting cylinder 10. The sliding connection has a connecting post 14 fixedly installed on the bottom wall of the connecting plate 13 away from the limiting strip 12. A ball bearing 15 is rotatably connected to the bottom end of the connecting post 14. An annular groove 9 is opened on the upper surface of the connecting ring 6. In use, the locking block 8 on the bottom wall of the connecting ring 6 can be inserted into the locking groove 7 on the upper surface of the annular connecting seat 3. Then, the connecting cylinder 10 is rotated so that the connecting post 14 at one end of the connecting plate 13 rotates to the top of the connecting ring 6. Then, the adjusting threaded rod 11 is rotated. Through the threaded connection between the threaded rod 11 and the connecting plate 13, the connecting plate 13 is driven to move the connecting post 14 and the ball bearing 15 at the bottom end of the connecting post 14 downward until the ball bearing 15 contacts the bottom wall of the annular groove 9 on the upper surface of the connecting ring 6.

[0029] In a preferred embodiment, two air inlets 25 are symmetrically arranged on the outer wall of the filter housing 1, and both air inlets 25 are located below the first partition 2. A second partition 26 is fixedly arranged inside the filter housing 1 and above the first partition 2. An exhaust fan 27 is installed on the second partition 26. An exhaust port 28 is provided at the top of the filter housing 1. A door 29 is connected to the front surface of the filter housing 1 by a hinge. A sealing strip is provided at the edge of the door 29 that contacts the filter housing 1. A handle is provided on the surface of the door 29. In use, external air can enter the filter housing 1 through the two air inlets 25 via the exhaust fan 27, be filtered by the filter cartridge, and then be discharged from the filter housing 1 through the exhaust port 28 at the top of the filter housing 1.

[0030] In this embodiment, the drive motor and exhaust fan 27 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0031] The working process of this utility model is as follows: First, the dust in the gas discharged into the filter box 1 is filtered by the filter cylinder set on the bottom wall of the connecting ring 6. At the same time, the drive gear 5 can be driven to rotate by the drive motor. Then, through the meshing between the rotating drive gear 5 and the meshing gear 4, the annular connecting seat 3, the connecting ring 6 and the filter cylinder set on the bottom wall of the connecting ring 6 are driven to rotate and adjust. Then, the filter cylinder is rotated to contact the cleaning brush 17, so that the dust on the surface of the filter cylinder is cleaned by the cleaning brush 17, so as to avoid the filter cylinder from being blocked and affecting the use of the filter cylinder for filtering dust.

[0032] When the bristles on the cleaning brush 17 become curled or damaged and need to be replaced after a period of use, you can first pull the connecting rod 16 to remove the cleaning brush 17 from the bottom wall of the filter box 1, and then replace the cleaning brush 17. Next, press the two connecting plates 21 to open the two clamping rings 20. Then place the connecting rod 16 between the two clamping rings 20, and then release the connecting plates 21. At this time, the spring 22 squeezes and pushes the two connecting plates 21, and then pushes the two clamping rings 20 closer together through the two squeezed and pushed connecting plates 21. Then, the two clamping rings 20 are pushed closer together by the two clamping rings. The retaining ring 20 clamps and fixes the connecting rod 16 fixedly connected to one side of the cleaning brush 17. At the same time, the locking connection between the limiting groove 24 on the connecting rod 16 and the limiting block 23 further improves the stability of the installation and fixing of the connecting rod 16 and the cleaning brush 17. This structure allows for quick installation, fixing, disassembly, replacement, and cleaning of the cleaning brush 17, preventing damage or curling of the bristles due to prolonged use, which would affect the cleaning effect of the cleaning brush 17 on the dust adhering to the filter cartridge surface. The above is the working principle of this building electrical dust removal device.
