Description

Technical Field

[0001] The present invention relates to the technical field of anti-dust and dust suppression devices, and particularly relates to an automatic anti-dust sprinkling device for building construction. Background Art

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where construction operations are carried out is called the "building construction site" or "construction site", also known as the construction site.

[0003] At the construction site of building construction, various construction operations will be carried out. During this process, dust is often generated, causing dust to fly at the construction site, which will seriously affect the construction environment. Moreover, the flying dust is easy to enter the respiratory system of the human body and is also easy to enter the eyes, resulting in discomfort in the breathing and eyes of construction workers. Therefore, it is necessary to carry out dust suppression treatment on the construction site of building construction to prevent the generation of dust.

[0004] In the prior art, spraying equipment is often used to carry out anti-dust and dust suppression treatment on the building construction site by spraying water mist. However, the nozzle angle of the existing spraying equipment for anti-dust is fixed and can only spray in a single direction. Therefore, in actual use, the spraying range of the water mist is relatively small, the dust suppression treatment effect is relatively poor, and the practicability is insufficient.
