As shown in fig. 3, the intelligent rain and sewage diversion intercepting well control process of the embodiment operating in a multi-mode is as follows:

when the rainless days are not rained (namely, the readings of the rain gauge are equal to 0), the liquid level in the cylinder reaches the pump starting liquid level h2 of the submersible sewage pump 1, the control cabinet 23 controls the single submersible sewage pump 1 to be opened, the lower opening type gate 15 to be closed, the first electric butterfly valve 26 to be opened, the second electric butterfly valve 27 to be closed, and drought sewage on the sunny days to be intercepted to a sewage pipe network and flow to a sewage treatment plant for treatment; the water level in the shaft reaches the pump stopping water level h3, and the submersible sewage pump is closed.

When rainfall (namely, the reading of a rain gauge is greater than 0) and the liquid level is less than the river channel control water level h1, the lower open type gate 15 is not opened, after one rainfall is finished, if the gate is not opened, the liquid level in the cylinder reaches the pump starting liquid level h2 of the submersible sewage pump 1, the control cabinet 23 controls the two submersible sewage pumps 1 to be opened, the accumulated running time of the double pumps is set to be t1, the preset time t2 is set according to the initial rainfall of the interception of the intercepting well, when the accumulated running time t1 of the two submersible sewage pumps 1 is smaller than the preset time t2, the control cabinet 23 controls the two submersible sewage pumps 1 to be opened, the electric butterfly valve 26 is opened, the electric butterfly valve 27 is closed, sewage in the cylinder is reached in the sewage system, and when the water level is reduced to the pump stopping liquid level h3, and the pumps are stopped running; when the accumulated running time t1 of the two submersible sewage pumps 1 reaches the preset time t2, the residual water is regarded as rainwater, the control cabinet 23 controls the two submersible sewage pumps 1 to be opened, the electric butterfly valve 26 is closed, the electric butterfly valve 27 is opened to drive the rainwater into a rainwater system, and when the water level is reduced to the pump stopping liquid level h3, the submersible sewage pumps 1 stop running.

In the rainfall process, after the liquid level sensor 4 detects that the water level in the cylinder 24 reaches the river channel control water level h3 in real time, the control cabinet 23 also sends out instructions to control the two submersible sewage pumps 1 to be closed, and simultaneously, the lower open gate 15 is opened, so that the safety of flood discharge is ensured.

After the rainfall process is finished, the rainfall gauge 22 monitors that the gate is closed 30min after the rainfall is stopped. At this time, a large amount of rainwater pipelines at the upstream are still submerged below the water level of the river, and a large amount of rainwater (residual rain) exists and needs to be discharged into a rainwater system or the river. Then, at the moment of the same starting operation t3 of the two submersible sewage pumps 1, the electric butterfly valve 26 is opened, the electric butterfly valve 27 is closed, and the dirty sinking impurity water at the bottom of the intercepting well is conveyed into a sewage pipeline; after the time t3 is over, the submersible sewage pump 1 continues to operate, at the moment, the electric butterfly valve 26 is closed, the electric butterfly valve 27 is opened, and then the residual rainwater of the whole upstream pipeline system is lifted into a rainwater pipeline, so that the later residual rainwater diversion is realized.

Considering that emergency power failure condition occurs and larger rainfall occurs, if no overflow weir plate 18 is arranged, the lower open gate 15 is closed, then the upstream rainwater pipe network is prone to waterlogging risk, so that the overflow weir plate 18 is arranged, the height of the overflow weir plate 18 is higher than the river liquid level h1, the river water is prevented from flowing backward, the lower open gate 15 is not required to be opened when emergency condition occurs, rainwater is turned to one side of the river channel through the overflow weir plate, flood is timely discharged, and meanwhile the risk of full filling of the barrel is avoided.
