[0002] In residential communities, rainwater wells are common facilities. Their main function is to carry rainwater discharged from residential buildings and discharge it into nearby rivers through rainwater pipes. In actual use, since rainwater pipes are usually set on one side of the balcony of a building, residents often discharge the waste water from washing machines into rainwater wells through rainwater pipes, resulting in a large amount of domestic water being discharged directly into the river without treatment, causing serious pollution to the river.
[0003] In the related art, a partition wall is provided in the rainwater well to separate the rainwater well and a control valve is provided on the partition wall. A sewage pipe connecting the sewage well and the rainwater well is also provided, and a lifting pump is provided to pump the water in the rainwater well into the sewage pipe. When it is sunny, the water discharged into the rainwater well is usually sewage, and the sewage will be pumped into the sewage pipe through the lifting pump; when it is rainy, the control valve will be opened so that the water in the rainwater well can be discharged into the nearby river through the drainage pipe on the other side of the rainwater well. In the above technology, although rainwater and sewage are separated, since sewage and rainwater share the rainwater well, a part of sewage and garbage will remain in the rainwater well, causing the subsequent rainwater to easily bring this part of sewage and garbage into the river during the flushing process.

[0007] By adopting the above technical solution, when it is sunny, the water discharged into the rainwater well is usually sewage. At this time, the drainage box is in the sewage discharge position, so that the first butt joint is connected to the sewage inlet of the drainage box, and the sewage enters the sewage chamber of the drainage box through the sewage inlet, and then the sewage is discharged into the sewage pipe through the lifting pump assembly. When it is raining, the water discharged into the rainwater well is usually rainwater. At this time, the drainage box is in the drainage position, so that the first butt joint is connected to the rainwater inlet of the drainage box, and the rainwater enters the rainwater chamber of the drainage box, and enters the output pipe through the rainwater outlet.
