After receiving the signal that the dust concentration exceeds the standard, the control unit 25 will send a start instruction to the pump 6 according to the preset program and parameters. The pump 6 starts working after receiving the start instruction from the control unit 25, and then the water can be pumped out from the inside of the water storage device body 7 and transported to the atomizing spray gun 16 through the retractable liquid guide tube 5. Then the atomizing spray gun 16 will spray the water into the air. The dust concentration generated at the construction site can be monitored in real time through the dust concentration sensor 24. Therefore, when the dust concentration exceeds the set threshold, the spray system can be automatically started, making the dust reduction work more accurate, and can effectively reduce the dust content in the air at the construction site.

By starting the first motor 4, the atomizing spray gun 16 can be adjusted. The spraying direction can be adjusted. By starting the second motor 13, the spraying angle of the atomizing spray gun 16 can be adjusted, which not only enables the atomizing spray gun 16 to cover a larger construction area, ensures the comprehensiveness and uniformity of the dust reduction effect, and effectively reduces the impact of construction dust on the surrounding environment, but also in different construction stages and working environments, such as different floors of a building, the shape and layout of different construction areas, etc., the spraying direction and angle can be flexibly adjusted to make the dust reduction work more in line with actual needs, and in complex construction sites, such as where there are obstacles, irregular terrain or multiple construction areas working in parallel, the spraying direction and angle can be adjusted to avoid obstacles and ensure the smooth progress of dust reduction.

[0043] In addition, during different stages such as foundation construction, main construction, and decoration construction, the construction site and work content are constantly changing.
