The dust-proof net mechanism also includes a driving component for rotating the first pulley 8.

[0030] The driving assembly includes a forward and reverse motor 14, which is fixedly connected to the steel beam 3 on the left side, and the output shaft of the forward and reverse motor 14 is fixedly connected to a transmission shaft 15, and the transmission shaft 15 is fixedly connected to the middle part of the first pulley 8; during operation, the forward and reverse motor 14 drives the transmission shaft 15 to rotate, and the transmission shaft 15 drives the first pulley 8 to rotate, thereby rotating the wire rope loop 10.

[0031] The wire rope loop 10 is wrapped around the outside of the first pulley 8. By arranging the wire rope loop 10 around the outside of the first pulley 8, the friction between the first pulley 8 and the wire rope loop 10 can be increased, and the wire rope loop 10 can be prevented from slipping on the outside of the first pulley 8.

[0035] Working principle:

[0036] When the system is in use, the high-pressure micro-mist dust reduction humidifiers 7 at the left and right ends respectively deliver high-pressure mist to the left and right ends of the spray pipe 6, and the high-pressure mist fills the interior of the spray pipe 6 and sprays downward through the spray holes on the wall of the spray pipe 6, thereby achieving the effect of spraying and dust reduction. At the same time, through the setting of the dust-proof net 11, the fluidity of the air in the foundation pit 1 can be reduced, thereby reducing the dust raised in the air of the foundation pit 1. At the same time, the dust-proof net 11 can absorb and filter the dust in the air, thereby playing a role in dust removal; when the dust-proof net 11 absorbs a certain amount of dust, the transmission shaft 15 can be driven to rotate by the forward and reverse motor 14, the transmission shaft 15 drives the first pulley 8 to rotate, the first pulley 8 drives the wire rope ring 10 to rotate counterclockwise, and the wire rope ring 10 moves to the right to the crown beam 2 of the waiting foundation pit 1, thereby shrinking the dust-proof net 11 to the right, and then the high-pressure water gun cleans the dust-proof net 11 that has shrunk to the right, and after the dust on the dust-proof net 11 is cleaned off, the same principle is followed, and the reverse operation is performed, thereby expanding the dust-proof net 11 to reset.

[0037] To sum up, the system can spray and reduce dust on the entire sky above the foundation pit 1 through the cooperation of the spray pipe 6 and the high-pressure micro-mist dust reduction humidifier 7, thereby preventing dust from spreading from the sky directly above the foundation pit 1 to the surrounding areas, greatly improving the dust prevention effect of the system, and the dustproof net 11 arranged in the system can not only reduce the amount of dust raised by reducing the fluidity of the air above the foundation pit 1, but also reduce the dust content in the air above the foundation pit 1 by absorbing dust, thereby further improving the dust prevention and dust reduction effects of the system; the system can drive the wire rope loop 10 to rotate counterclockwise through the driving component, so that the dustproof net 11 can shrink to the right side, so as to facilitate the cleaning of the dust on the dustproof net 11, so that the dustproof net 11 can continue to maintain a good adsorption effect on dust, thereby ensuring the continuous and efficient dust reduction effect of the system.
