Description

Technical Field

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

[0002] Construction is a complex, multi-stage process involving design, planning, material procurement, construction, quality control, safety management, and project acceptance. Dust suppression devices are crucial for ensuring a clean construction site environment and reducing dust pollution. These devices utilize various technical principles to effectively reduce airborne dust particles and improve the quality of the construction environment.

[0003] Announcement No. "CN217139762U" discloses a dust reduction device for construction, comprising a main body and a dust reduction component for processing dust in the air, wherein the dust reduction component comprises a rotating block arranged on one side of the main body, a fixed plate arranged on the top of the rotating block, a gear sleeved on the other side of the rotating block, a cylinder arranged on the other side of the main body, a telescopic rod arranged on one side of the cylinder, a rack arranged on one side of the telescopic rod, a water tank arranged on the top of the fixed plate, and fixed blocks respectively arranged on both sides of the water tank. The utility model provides a main body, a telescopic rod, a rack, a water tank, a fixed block and an atomizing nozzle. The rack drives the gear to move back and forth, so that the rack drives the fixed plate on the top of the rotating block to rotate, and at the same time the water pump sprays water into the construction environment through the atomizing nozzle, thereby solving the problem that the existing equipment cannot reduce dust in multiple directions in the construction environment, which easily leads to low dust reduction efficiency of the equipment and affects the practicality of the dust reduction operation of the equipment.

[0004] Although the above-mentioned utility model solves the problem that the existing equipment cannot reduce dust in multiple directions in the building environment, which easily leads to low dust reduction efficiency of the equipment and affects the practicality of the equipment's dust reduction operation, the height of the atomizing nozzle is fixed, resulting in a relatively fixed coverage range of the water mist sprayed by the atomizing nozzle. However, at the construction site, the height and distribution of dust may change with the progress of the operation and weather conditions. If the height of the atomizing nozzle is fixed and cannot be adjusted, it will not be able to flexibly respond to dust at different heights, resulting in unsatisfactory dust reduction effect. At the same time, if the height of the nozzle cannot be fixed, the sprayed water mist will not be able to effectively cover the target area, thereby causing a waste of water resources.
