By setting the dustproof net 111, specifically the dustproof net 111 is used to intercept external dust and garbage. When the dustproof net 111 needs to be disassembled, the dustproof net 111 can be disassembled by pulling it hard to separate it from the elastic blocks 113, which is convenient for subsequent maintenance or cleaning. Since the dustproof net 111 is in the outside world and is attached with a lot of garbage and dust, it is convenient for disassembly and maintenance.
[0030] The left and right sides of the shielding cover 121 are fixedly connected with a fixed shaft 211, and the two support frames 122 are provided with a rotating hole inside.

[0034] A specific application of this embodiment is:
[0035] When in use, the mounting plate 1 is mounted on the factory building, and then the dust-proof net 111 is inserted into the positioning groove 112 through the positioning block 114 to position the dust-proof net 111. When the dust-proof net 111 contacts the elastic block 113, the elastic block 113 will be squeezed and pushed, so that the dust-proof net 111 contacts the front of the ventilation pipe 11 smoothly. Then, the elastic block 113 is reset by the elastic action, and the dust-proof net 111 is clamped and fixed, and the installation of the dust-proof net 111 is completed. When the dust-proof net 111 needs to be removed, the dust-proof net 111 is pulled hard to make it fall off.

Since the dust screen 13 is in the factory, there is less dust attached, and the use of bolts to fix it can improve safety. After the installation is completed, the fan 14 is started to blow the air out of the outside The air is blown into the factory building for heat dissipation and ventilation. When it rains, the rotating shaft 242 drives the block 243 to rotate together, so that the block 243 rotates to the straight slot position opened on the plug plate 123, and then the shielding cover 121 is flipped downward, so that the plug plate 123 smoothly leaves the fixed plate 124, and the shielding cover 121 rotates on the support frame 122 through the fixed shaft 211. The shielding cover 121 will be in a falling position due to its own gravity, thereby blocking the front of the ventilation pipe 11, which can reduce the rainwater from entering the ventilation pipe 11, effectively play a protective role, and reduce the rainwater from entering the factory building. The shielding cover 121 is preferably a cover for the ventilation duct 11, and the shielding cover 121 is preferably a cover for the ventilation duct 11. When the shielding cover 121 is needed to be opened upward, the shielding cover 121 is flipped upward to allow the plug-in plate 123 to be plugged into the plug-in block 241 and to contact the fixing plate 124. The rotating shaft 242 is then rotated to drive the card block 243 to rotate above the plug-in plate 123. The card block 243 limits and fixes the plug-in plate 123 by cooperating with the limiting shaft 244. The shielding cover 121 is then fixed, and the ventilation duct 11 can be opened from the front.
