The drain pipe 8 is connected to a municipal sewage treatment system, and the water supply pipe 7 is connected to a rainwater collection site.

Under initial condition, under the effect of first spring 6, the water inlet of delivery pipe 7 is located the centre of first baffle 4 and second baffle 5, and when being in the initial stage of raining, the rainwater that contains the pollutant on the road flows into ring channel 3 in from water drainage channel 2 after, can't get into in the delivery pipe 7, can only follow in the sewage treatment system of blow off pipe 8 row city. In this in-process, when the guiding gutter 21 was flowed through to the rainwater, the solid pollutant in the rainwater will be held back in the top of filter screen 211, a period of time back, pollutant on the road is also washed clean by the rainwater, the rainwater of discharging this moment is comparatively clean, the solid pollutant that the filter screen 211 top was held back also reaches the maximum value simultaneously, the whole quality of filter screen 211 increases to the maximum value, can promote connecting rod and sealing plug 9 to move down to in the blow off pipe 8 this moment, sealing plug 9 can plug up blow off pipe 8, the rainwater can't get into in the blow off pipe 8 this moment, only can be at ring channel 3 gathering, promote first baffle 4 simultaneously and slide along ring channel 3, when pushing first baffle 4 to the delivery pipe 7 right side, the clear rainwater of later stage can be discharged into the appointed place by delivery pipe 7, thereby accomplish the collection of clean rainwater. The pollution rainfall volume of going into in the municipal sewage treatment system like this is less, can not increase municipal sewage treatment's pressure and lead to surface gathered water, accomplishes the collection to the rainwater in the city again simultaneously, improves the collection efficiency of sponge city to the rainwater greatly. After the rain is rainy and sunny, the first spring 6 pushes the first baffle 4 to be displaced to the left side of the water supply pipe 7 again along with the loss of the rain water in the annular groove 3. Simultaneously clear up remaining solid contaminant above the filter screen 211 after the rain, the second spring 11 will promote sealing plug 9 and filter screen 211 to shift up and reset, makes this device can continue to use when raining next time.
