[0030] In one embodiment, in order to facilitate observation of the operating status of the equipment inside the cabinet 11, an observation window 16 is installed on one side of the cabinet door 12, and a cabinet lock 17 is installed on one side of the cabinet door 12 to prevent the cabinet door 12 from being opened accidentally.

[0031] The ventilation mechanism 20 includes a mounting plate 21, a filter plate 23 and an electric guide rail 26. The mounting plate 21 is evenly spaced and installed inside the cabinet 11 for mounting and fixing electrical components. Ventilation holes 22 are evenly spaced inside the mounting plate 21 to connect the internal space of the cabinet 11. Slide rails 35 are symmetrically installed inside the cabinet 11. Slide rails 35 are slidably connected inside the slide rails 35. One side of the filter plate 23 is fixedly connected to the slide rail 36. The slide rail 36 cooperates with the slide rail 35 to facilitate the rapid installation of the filter plate 23 in the cabinet 11, and the filter plate 23 can be removed for maintenance and cleaning when necessary. The electric guide rail 26 is symmetrically installed on the inner bottom of the cabinet 11. The movable end of the electric guide rail 26 is fixedly connected to a storage box 27. One side of the storage box 27 is installed A cover plate 28 is provided, and a storage box 27 is provided for storing dust scraped by a soft brush 34. A suction fan 29 is installed on one side of the storage box 27. The air outlet of the suction fan 29 is connected to the storage box 27, and the air inlet of the suction fan 29 is connected to a guide pipe 32. The guide pipe 32 is provided to cooperate with the suction fan 29 to collect dust to prevent dust from splashing in the cabinet 11. A timing switch 31 is installed on one side of the suction fan 29, and the timing switch 31 is electrically connected to the suction fan 29. A fixing frame 33 is symmetrically fixedly connected to one side of the storage box 27, and a soft brush 34 is fixedly connected to one side of the fixing frame 33. The soft brush 34 is provided to clean the surface of the filter plate 23, and the timing switch 31 is provided to control the cleaning interval, so that the filter plate 23 can be cleaned in time when too much dust accumulates.

[0032] In one embodiment, in order to prevent the filter plate 23 from sliding in the cabinet 11, a limit plate 25 is symmetrically provided on one side of the filter plate 23, and a bolt 24 is threadedly connected to the inner side of the limit plate 25, and one end of the bolt 24 is threadedly connected to the mounting plate 21. The limit plate 25 is provided to cooperate with the bolt 24 to limit the filter plate 23 to prevent the filter plate 23 from shifting in position after installation.

[0033] Optionally, a cooling fan or other equipment is installed at the heat dissipation hole 13 to improve the heat dissipation efficiency.

[0034] When the utility model is in operation, the electrical components are mounted on the mounting plate 21, the filter plate 23 is placed in the cabinet 11, the slider 36 is inserted into the slide rail 35 and slides in the slide rail 35, after the filter plate 23 is installed in the cabinet 11, the limit plate 25 is connected to the mounting plate 21 by the bolt 24, the filter plate 23 is limited by the limit plate 25 to prevent the position of the filter plate 23 from shifting, the start-up interval of the electric guide rail 26 and the suction fan 29 is set by the timing switch 31, the cabinet door 12 is closed, the operating status of the internal equipment of the cabinet 11 is observed through the observation window 16, the cabinet door 12 is locked by the cabinet lock 17, and the cabinet 11 is closed. The heat generated by the internal equipment is discharged through the ventilation holes 22 and the heat dissipation holes 13. When the air inside and outside the cabinet 11 is exchanged, part of the dust carried is intercepted by the dustproof net 14, and the fine dust is intercepted by the filter plate 23. After the filter plate 23 has been used for a certain period of time, too much dust adheres to its surface, which will affect the ventilation efficiency. The electric guide rail 26 and the suction fan 29 are started. The electric guide rail 26 drives the storage box 27 and the soft brush 34 to move. The soft brush 34 scrapes the dust on the surface of the filter plate 23. At the same time, the suction fan 29 cooperates with the guide tube 32 to suck the scraped dust into the storage box 27. After cleaning, open the cover 28 to take out the dust.
