Description

Technical Field

[0001] The utility model relates to the technical field of construction site dust prevention equipment, in particular to a construction site dust prevention device. Background Art

[0002] During the construction process at a construction site, a large amount of dust and a complex working environment often cause dust to fly, which not only affects construction efficiency, but also has a negative impact on workers' health, especially respiratory health. In order to deal with this problem, construction sites usually use special dust control devices for management and control. These dust control devices monitor the dust concentration in the air in real time through precise dust sensors, and automatically start fans, spray systems or other dust control equipment based on the monitoring data to effectively reduce the generation and spread of dust.

[0003] In the prior art, dust removal devices usually use a fixed spraying pattern, which determines the size of the cleaning area that can be covered, resulting in the inability to spray over a large area in actual use and the inability to effectively cover the entire cleaning area, especially when dealing with large areas of dust. Uneven spraying or failure to adjust in time will affect the dust removal effect and reduce the cleaning efficiency and performance of the equipment. Utility Model Content
