The working principle of the present invention is: when rainfall occurs, the first rain sensor senses the occurrence of rainfall, and the feedback signal is sent to the control box to close the solenoid valve, and at the same time, the rainwater flows into the water collecting pipe through the water collecting bucket. If a rainfall does not reach the initial stage Rainfall, the rainfall is over, the solenoid valve is opened, and the program ends when the water in the water collecting pipe is emptied. If the rainfall in one rainfall reaches the initial rainfall, the float switch is triggered, indicating that the initial rainfall has fallen. After that, the PLC starts to record the rainwater collection time. When the rainwater time set according to the collection distance is reached, the initial rainwater abandonment ends, and the lifting flexible flap (electric or hydraulic) is closed to discharge the later rainwater to the natural water body. At this time, the second rain sensor will monitor the entire rainfall process. When the rainfall ends and the second rainfall begins, the recording interval should be as small as the set value, and it can be directly discharged without re-discarding the flow. During this process, when one or When it rains many times, the lifting type flexible flap door (electric or hydraulic) is closed, and the timing is restarted. When the rain stops each time during this process, the lifting type flexible flap door (electric or hydraulic) is opened, and the timing is restarted. When it is greater than the set value, the solenoid valve is opened to empty the water in the water collection pipe, and the flow is discarded again after the program ends.

When the present invention is used, when there is no rainfall, the adjustable shut-off valve is in the open state, and the man-made sewage generated by the road can directly run off to the sewage pipe through the jettison pipe. When rainfall occurs, the rain gauge calculates the amount of incipient rain. When the set value is reached, the rain gauge will feed back a signal to the control box to start recording the rainwater collection time. When the rainwater collection time set according to the collection distance is reached, the initial rainwater abandonment ends, and the adjustable intercepting valve is closed to make the later stage Rainwater is discharged to natural bodies of water through drains. Determine the later rainwater discharge time according to the rain frequency. When the rainfall ends and the second rainfall begins, the recording interval should be less than the set value, and it can be discharged directly without re-abandonment. When it is greater than the set value, it will be re-abandoned. Therefore, the rainfall type abandonment well can reduce more than 80% of the pollutants entering the natural water body, effectively solving the pollution of the river by the initial rainwater.

It should be understood that, the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of Changes or substitutions should fall within the protection scope of the present invention.
