Abstract
A dust suppression system has one or more fluid dischargers configured to discharge a fluid capable of suppressing generation of dust to a work area of a building by remote operation. The fluid discharger includes a discharge nozzle configured to discharge the fluid; a first swivel joint structure including a first rotating-side body connected to and supporting the discharge nozzle and a first fixed-side body rotatably supporting the first rotating-side body; a first electric linear motion mechanism including a first support part and a first movable part supported by the first support part in a linearly movable manner; and a first rotation mechanism configured to convert linear motion of the first movable part into rotational motion to rotationally displace the first rotating-side body. The dust suppression system can further reduce power consumption as well as can accurately discharge a fluid from a fluid discharger to a predetermined work area.
