A FLOW CONTROL DEVICE OF STORM OVERFLOW CHAMBER COMBINED WATER QUALITY MEASUREMENT AND WATER LEVEL

摘要

The present invention relates to a water level and water quality measurement and flow control device for a storm overflow chamber which can open and close an opening and closing plate according to the water level of rainwater with high pressure and can passively open and close the opening and closing plate by measuring the water quality and water level inside a sewage conduit in real time, thereby discharging rainwater into a stream or a river and introducing sewage and initial rainwater into the storm overflow chamber by passively controlling the opening and closing plate according to the water level inside the sewage conduit, selectively introducing sewage into the sewage conduit according to the water quality without regard to the water level after measuring the water quality inside the sewage conduit in real time, and opening and closing the opening and closing plate without power according to the water level of rainwater with high pressure when electricity is cut off in case of emergency by including a floating member and a weight joined to the bottom side of the opening and closing plate.
