3) According to the invention, the rotation of the water collecting plate can control the rainwater to be switched between the first state and the second state, and the switching between the first state and the second state is controlled by the water inflow and the opening of the automatic ball valve in the flow abandoning chamber. In rainy days, runoff rainwater at the early stage is intercepted, and runoff rainwater at the middle and later stages is normally discharged. The high-pollution rainwater and the middle and later stage runoff rainwater are separately discharged, so that the pollution load of the municipal rainwater pipe network can be effectively reduced, and rainwater with higher pollution concentration is prevented from entering a river, lake and water system;
4) In the invention, the siphon drainage system drains the rainwater in the water storage chamber through the siphon drainage pipe, the rainwater can be drained when the water surface of the rainwater reaches the height of the siphon elbow, and only the rainwater above the inlet end of the siphon can be drained, but not directly drained. The height of the siphon elbow and the distance between the siphon inlet end and the bottom of the water storage chamber can be uniquely designed according to different conditions, so that the drainage time and the drainage quantity of each rainwater inlet in rainy days are different. This inlet for stom water of a certain amount is set up in whole urban rainwater system, if the lower region of waterlogging risk etc. can store partly rainwater, also can carry out the wrong peak to the rainwater and discharge, reaches the effect that rainwater pipeline peak value under the extreme rainfall condition reduces, the peak time delay after to reduce because of the not enough urban waterlogging problem that causes of rainwater pipeline drainage ability.
