Description

Technical Field

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

[0002] The safety facilities at the construction site include not only structures such as guardrails and protective nets for direct protection, but also indirect protection equipment such as dust suppressors and sewage pumps. Among them, the role of the dust suppressor is to "wash down" the dust particles floating in the air, converting them into muddy water, and finally pumping away the muddy water to ensure that the air at the construction site will not cause significant harm to the respiratory health of the workers. These facilities together constitute the safety protection system of the construction site, providing workers with a relatively safe and healthy construction environment;

[0003] The dust suppression equipment currently used only reduces dust by spraying water mist. Its design is simple but its functions are relatively limited. These devices cannot be adjusted according to weather changes or the amount of dust generated by construction. Instead, they continuously spray water at a fixed power. This method not only lacks environmental adaptability and energy saving, but also leads to unnecessary high energy consumption.

[0004] The dust suppression devices currently used often involve cumbersome steps during installation, especially when fixing the equipment on the construction fence. Faced with the construction site, this installation method is extremely time-consuming and labor-intensive, which not only prolongs the preparation time, but also increases the labor cost problem.

[0005] Therefore, a dust suppression device for construction is needed to improve the above problems. Utility Model Content

Only the pull rope needs to be pulled, and multiple groups of clamping components can be synchronously pulled open for clamping and fixing. The installation of the device is relatively simple, thereby solving the problem that the dust suppression device currently used often involves cumbersome steps during the installation process, especially when the equipment is fixed on the construction fence, facing the construction site, this installation method is particularly time-consuming and labor-intensive, which not only prolongs the preparation time, but also increases the problem of labor cost.
