Title:
WATER GATE OPENING CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2015113635
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent flooding damage in a drainage channel upstream of a water gate and a water quality standard excess in a drain port downstream of the water gate, by eliminating manual operation of opening the water gate at a job site.SOLUTION: A system is provided for controlling opening of the water gate for making water of the drainage channel upstream of the water gate flow to the drainage channel downstream of the water gate from the upper side of a gate plate, by lowering and opening the gate plate by a lifting mechanism. The water gate opening control system comprises an opening determination device for determining the opening of the water gate for satisfying a predetermined standard on a water quality in the drain port for connecting the drainage channel to a public water area, by inputting a detection result of a water quality in the drainage channel upstream of the water gate and a water quality in the drainage channel downstream of the water gate and a detection result of a water level and a flow speed in the drainage channel upstream of the water gate and a water level and a flow speed in the drainage channel downstream of the water gate and an opening control device for controlling the opening of the water gate based on the opening determined by the opening determination device.
