Water body.

Generally speaking, the value of the timing duration of the timing module is the sum of the flow time _t1 of the farthest rainwater collection port in the collection branch pipe and the flow time _t2 from the outlet of the collection branch pipe to the diversion well. Of course, a certain compensation value can also be set according to the actual situation.

The rainfall is characterized by: with the increase of time, the rainwater gradually accumulates; when the rainfall reaches a certain threshold at a certain moment, it means that the rainfall at this time needs to be opened for interception and flood discharge. There is a certain distance, so the accumulated rainwater in the diversion well has not reached the critical value for flood discharge.

In view of this, when the rainwater in the rainwater collection port reaches the diversion well, it needs to be intercepted. Therefore, it is very meaningful to delay opening. Turning on the interception equipment at the most suitable time, on the one hand, can discharge floods in time, and can also prevent excessive sewage from entering the natural water body caused by early closure; the closure has a high degree of automation and good timeliness.
