The liquid level gauge can monitor the liquid level height in the collection pool in real time, and transmit the data back to the PLC control cabinet, which then controls the electromagnetic valve 17 to control its opening, closing or opening. When it rains, when the flow meter in the catchment channel detects water flow, it will feed back this information to the control center, and the control center will then control the valve 17b to open. Poor, it cannot be used directly, so the initial rainwater should be discarded.

When the flowmeter in the collection channel detects the inflow of rainwater, the PLC control cabinet controls the second solenoid valve 17b and the fourth solenoid valve 17d to open, the third solenoid valve 17c and the fifth solenoid valve 17e to close, and the discarded rainwater passes through the sewage branch pipe 14 It flows into the sewage collection main pipe 9, and the time for the rainwater to abandon the flow, that is, the time for the fourth solenoid valve 17d to open, is controlled within 10-30 minutes, and the specific time is determined according to the size of the rainfall. PLC control cabinet implementation. When the discarding time is over, the fourth solenoid valve 17d is automatically closed, and the third solenoid valve 17c is opened. When the liquid level gauge 8 in the sump detects that the liquid level in the sump is too high and the amount of water is too large, the control terminal will control the fifth solenoid valve 17e to open, and introduce part of the water in the sump into the sump branch pipe 16 to prevent the sump from the sump. 19 overflow.
