Title:
SEWAGE PIPE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/105964
Kind Code:
A1
Abstract:
The present invention relates to a sewage pipe control system. In a rainwater soil chamber, sewage is introduced through an upper inlet and collected, and the collected sewage is discharged through an outlet. An opening/closing plate for an inlet is coupled to the upper inlet of the rainwater soil chamber to be rotatable around a horizontal axis, and operates through gravity by being rotated to close the upper inlet as the amount of water introduced into the upper portion of the rainwater soil chamber increases while being inclined to open the upper inlet by its own weight, or is rotated by an actuator for an inlet to open and close the upper inlet. An inclination sensor measures an inclination of the opening/closing plate for an inlet. A water level sensor measures the level of water outside the rainwater soil chamber. A controller receives measured information from the inclination sensor and the water level sensor to control the actuator for an inlet.
