Embodiment 1
[0040] 1) When it rains, the single-chip microcomputer 19 controls the water inlet electromagnetic valve 2 to open through the electromagnetic valve controller 4, and the water outlet electromagnetic valve 11 closes, and the runoff flows into the concave overflow tank 3 through the runoff inlet pipe 1, and the concave overflow tank 3 can weaken the direct impact force of the runoff , and can disperse the sediment in the runoff. The runoff overflows with the concave overflow tank 3 and then is filtered by the support filter 5 and then flows to the upper surface of the conical water guide plate 6. After the runoff is evenly distributed by the conical water guide plate 6, it passes through the gap 17 flows into the storage chamber 7 along the side wall of the cylinder 16, so that the incoming water avoids directly impacting the liquid surface, and the elapsed time t 1 When the water level reaches the lower water level probe 10, the water level probe 10 sends a signal to the single...
Embodiment 2
[0045] Step (1) is the same as the monitoring process embodiment 1, the difference is that when the water level reaches the lower water level probe 10, the water will continue to flow in until the water level passes the time t 2 When reaching the upper water level probe 9, the load cell 13 records and sends the information into the single-chip microcomputer 19 to store it as the weight M 2 , timer 8 records time t 2 And the information is transferred to the single-chip microcomputer 19 and stored as t 2 , the single-chip microcomputer 19 and the electromagnetic valve control unit 4 control the water inlet electromagnetic valve 2 to close, and the water outlet electromagnetic valve 11 to open, so that the liquid in the flow storage chamber 7 can be quickly discharged;
[0046] In step (2), carry out following data processing in single-chip microcomputer 19: combine the height of known lower water level probe 10 i.e. low water level h 1 , The height of the upper water level pr...
