A dust-proof net replacement device, comprising rotary shafts and a replacement assembly, the rotary shafts comprising a first rotary shaft and a second rotary shaft, one end of a dust-proof net being wound on the first rotary shaft, the other end of the dust-proof net being wound on the second rotary shaft after passing through an air inlet of a fan cover, the replacement assembly being connected to the second rotary shaft and arranged, when a preset replacement condition is met, to drive the second rotary shaft to rotate and stop after replacing the dust-proof net. Via the arrangement of the rotary shafts and the replacement assembly, the present technical solution implements the automatic replacement of the dust-proof net, obviating the need for manual on-site dust-proof net replacement, and only requiring a certain amount of backup dust-proof nets. The present technical solution uses the replacement assembly to periodically and automatically rotate the rotary shafts to automatically replace the dust-proof net, thereby avoiding manual maintenance, decreasing maintenance costs for dust-proof net replacement, and reducing the amount of time required for manually performing dust-proof net replacement. |
