DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Such as Figures 1 to 4As shown in the figure, a secondary dust removal device for convenient dust cleaning includes an electrical cabinet 1 and a dust removal structure 2 provided on the electrical cabinet 1. The dust removal structure 2 includes a dehumidifier 3 and dust removal components 4 symmetrically arranged on both sides of the dehumidifier 3. A fixing frame 5 is provided between the bottom surface of the dehumidifier 3 and the top surface of the electrical cabinet 1. A dust-proof net plate 6 is provided at the air inlet of the dehumidifier 3. The dust removal component 4 includes a dust removal box 401, a dust filtering net plate 402 arranged inside the box, and a dust collection box 403 arranged inside the dust filtering net plate 402. A cleaning port 404 is opened on the top surface of the dust removal box 401, and a rotating plate 405 is rotatably connected at the cleaning port 404. The dehumidifier 3 and the dust removal box 401 are connected through a ventilation pipe 406, and the dust removal box 401 and the electrical cabinet 1 are connected through a blowing pipe 407. The electrical cabinet 1 is provided with a blowing port 101 corresponding to the pipe orifice of the blowing pipe 407.

[0024] As Figure 1 shown in the figure, the secondary dust removal device in the present utility model is similar in structure to the existing secondary dust removal device. For example, a patent with the publication number CN218963569U discloses a dust removal device for secondary protection of a power system. The main improvement point of the present utility model is that it can remove dust from the air entering the power protection cabinet, thereby preventing dust from entering the power protection cabinet. As Figures 1 to 4 shown in the figure, in the process of using a secondary dust removal device for convenient dust cleaning in the present utility model, air will enter from the air inlet of the dehumidifier 3. At this time, the dust-proof net plate 6 at the air inlet can initially remove dust, reducing the accumulation of dust in the dehumidifier 3. After being dehumidified by the dehumidifier 3, the dry air will enter the dust removal components 4 on both sides of the dehumidifier 3 through the ventilation pipe 406. The air in the dust removal components 4 will be sucked by the negative pressure fan 702 and rush towards the blowing pipe 407. During the flow of this air, it will pass through the dust filtering net plate 402 on the net plate frame 408. The dust filtering net plate 402 will filter the dust in the air, and the accumulated dust will fall into the dust collection box 403. At this time, the filtered air will enter the electrical cabinet 1 through the blowing pipe 407, and the blowing pipe 407 is the only air source of the electrical cabinet 1, preventing dust from accumulating in the electrical cabinet 1. When it is necessary to clean the dust collection box 403, we can pull out the dust collection box 403 through the dust collection handle 8 and clean it. When it is necessary to clean the dust removal box 401, the threaded covers 411 on the ventilation pipe 406 and the blowing pipe 407 in the dust removal box 401 are removed, so as to take out the dust removal box 401, which facilitates the staff to clean and maintain the dust removal box 401.

[0025] As Figure 3 and Figure 4 shown in the figure, the dust removal box 401 is provided with a net plate frame 408 at the dust filtering net plate 402. The net plate frame 408 is provided with a net plate groove 409 for fixing the dust filtering net plate 402. The side surface of the net plate frame 408 is attached to the dust collection box 403 and has the same height.

[0026] Specifically, in order to make the bottom surface of the dust filter mesh plate 402 at the same height as the top surface of the dust collection box 403, we set up a mesh plate holder 408 to lift the dust filter mesh plate 402. At the same time, a mesh plate groove 409 is opened on the mesh plate holder 408, so that the dust filter mesh plate 402 can be slidably connected in the mesh plate groove 409. Thus, when the rotating plate 405 is opened, the dust filter mesh plate 402 can be taken out from the mesh plate holder 408, which facilitates the staff to clean the dust filter mesh plate 402.

[0027] As Figure 3 and Figure 4 shown, a partition 7 is provided inside the dust removal box 401 on the outside of the dust filter mesh plate 402. A fan opening 701 is opened on the partition 7, and a negative pressure fan 702 is provided at the fan opening 701.

[0028] Specifically, by providing the negative pressure fan 702 on the partition 7, we can create a negative pressure environment in the dust removal box 401, and blow the dry air sent by the dehumidifier 3 towards the air blowing pipe 407, so that the air can stably flow towards the electrical cabinet 1; the negative pressure fan 702 can also control the flow rate of the air moving towards the electrical cabinet 1, preventing the reduction of the dust removal efficiency caused by inconsistent air flow rates.

[0029] As Figure 4 shown, external threads 410 are provided on the outer sides of the pipes of the ventilation pipe 406 and the air blowing pipe 407 inside the dust removal box 401. A threaded cover 411 that fits the external threads 410 and is used to fix the air pipes is provided inside the dust removal box 401. The threaded cover 411 is provided with an air outlet 412 having the same inner diameter as the ventilation pipe 406 or the air blowing pipe 407.

[0030] Specifically, in order to better clean and maintain the dust removal box 401, by providing the external threads 410 and the corresponding threaded covers 411 at the pipe orifices of the ventilation pipe 406 and the air blowing pipe 407, the ventilation pipe 406 and the air blowing pipe 407 can be fixedly connected to the dust removal box 401 during use. When maintenance is required, the threaded cover 411 can be removed and the dust removal box 401 can be taken off, which facilitates the staff to clean and maintain the entire dust removal box 401.

[0031] As Figure 2 and Figure 4 shown, the dust removal box 401 is provided with a dust collection port 413 that fits the side surface of the dust collection box 403. A dust collection handle 8 is provided on one side of the dust collection box 403 outside the dust removal box 401, and a rotation handle 9 is provided on the upper surface of the rotating plate 405.

[0032] Specifically, the opening of the dust collection port 413 can facilitate the staff to take out the dust collection box 403. When it is necessary to clean the dust in the dust collection box 403, the dust collection box 403 can be pulled out and cleaned through the dust collection handle 8, and the setting of the rotation handle 9 can facilitate the rotation of the rotating plate 405.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
