AI Technical Summary
Existing spray dust suppressant spraying devices can only be used outside tunnels and are not suitable for the limited space inside tunnels.
Design a dust suppression spraying device for tunnel railways, including a photoelectric detection system and two sets of symmetrically arranged spraying units. The device uses electromagnetic valves to control the start and stop of the spraying units, has a long and narrow structure to adapt to the space inside the tunnel, and achieves precise spraying of dust suppressant through the photoelectric detection system and programmable controller.
It achieves effective dust suppression within the tunnel, with good dust suppression effect, small space occupation, no impact on transportation capacity, stable and reliable operation, and easy maintenance.
