Document Type and Number:
WIPO Patent Application WO/2023/024232
Kind Code:
A1
Abstract:
The present invention relates to the technical field of municipal pipeline operation, and in particular to a municipal pipeline tail end water discharging control device. The device comprises: a fire hydrant (1), a water inlet connecting pipe (2), an electromagnetic valve (3), a main pipe (6) and an electromagnetic flowmeter (7) which are sequentially connected. A turbidity sensor (4) is mounted on the main pipe (6); the electromagnetic valve (3), the turbidity sensor (4) and the electromagnetic flowmeter (7) are all connected to a PLC automatic control system (5); and the tail end of the main pipe (6) is connected to a water discharging pipe (10). The present invention can achieve automatic control and recording changes of parameters such as turbidity, flow, and time in the flushing and water discharging process of a municipal water supply pipeline tail end, and is used for finely managing the municipal pipeline tail end water discharging process, thereby saving the water discharging quantity, improving the water discharging efficiency, and improving the water quality of a water supply pipeline.
