The joint of the water collecting tank 6 and the first branch pipe 4 and the second branch pipe 7 is respectively positioned on two different bottom surfaces of the water collecting tank 6, the horizontal positions are far away from each other, the top of the water collecting tank 6 is fixedly connected with two conductive columns 14, one conductive column 14 is communicated with an external power supply, the other conductive column 14 is electrically connected with an electromagnet 13 through a conducting wire, the diameter of the first branch pipe 4 is larger than that of the second branch pipe 7, so that when water flows in, when the water flow is small, because the water flow does not exceed the diameter of the first branch pipe 4, in this state, the inflow amount of the first branch pipe 4 is the same as the outflow amount of the second branch pipe 7, the water level cannot rise, the second branch pipe 7 is hermetically connected with an electromagnetic valve 15, the electromagnetic valve 15 is electrically connected with the conductive columns 14, when the water level reaches the height of the conductive columns 14, the electromagnetic valve 15 closes the second branch pipe 7, and at this time, the water level is kept at the height above the conductive columns, the connecting part of the two sewage discharge pipes 3 is communicated with an exhaust pipe 8, the exhaust pipe 8 is communicated with the external road surface, the sliding block 11 is made of a magnet material, and the magnetism of the sliding block is opposite to that of the electromagnet 13, so that the sliding block 11 and the electromagnet 13 are far away from each other in the power-on state of the electromagnet 13.

The initial effect of the road runoff is that in the initial stage of the runoff, disproportionate phenomenon occurs, most pollutants are washed into surface water, which means that the pollution load carried by rainwater is large in the initial stage of rain, and because the intensity of rainfall in the analysis of the road runoff is also in direct proportion to the time of the initial effect, which means that in the state of small rainwater, the washing of pollutants is output with a constant content, so that in this state, the discharged rainwater always carries more pollutants, and in the state of large rainwater amount, the initial effect time is short, so that the rainwater carries trace road pollutants after a period of time, and the rainwater can be directly discharged into a roadside river in this state.

When the invention is used, in an initial state, the slide block 11 and the iron core in the electromagnet 13 without electricity are mutually attracted, so that the block 10 is in a state of sealing the first outlet, rainwater is completely discharged through the second outlet, the state is divided into two states, when the rainwater amount is larger, the flow of the sewage discharge pipe 3 is larger, so that the flow passing through the first branch pipe 4 completely covers the diameter of the first branch pipe 4, and because the diameter of the second branch pipe 7 is smaller than that of the first branch pipe 4, the water in the water collecting tank 6 gradually rises because the water enters into the water collecting tank and is larger than the water to be discharged, and because the diameter difference between the two branch pipes is smaller, the water level growth speed is slower, namely the time of the initial effect is met, and when the water level of the water collecting tank 6 reaches a full water state, the water collecting tank is mutually contacted with the conductive posts 14 arranged on the water collecting tank 6, so that the two conductive posts 14 are mutually communicated by taking water as a medium, on one hand, the electromagnetic valve 15 is enabled to close the second branch pipe 7, the water level stays at the current water level, water in the drain pipe 3 is completely drained through the liquid outlet pipe 5, on the other hand, the electromagnet 13 is enabled to be electrified, the blocking block 10 is pushed to seal the second outlet under the action of opposite magnetism, and at the moment, after the initial effect is met, rainwater does not carry more pollutants and can be directly drained to a river through the first outlet; under another kind of state, the rainfall is less, and the inflow of first branch pipe 4 is the same with the water yield of second branch pipe 7, and the header tank 6 water level can't rise this moment, and then the rainwater will be discharged all the time and get into after the second export the external sewage treatment structure by the processing, makes the rainwater that carries some pollutants all the time unable direct entering river like this, avoids the pollution to the river.

After the rainwater stops, because the water level in the water collecting tank 6 is always kept at the height of the conductive post 14 at this time, if rainfall continues in a later period of time, because pollutants on the road are not accumulated to a certain extent after being cleaned up, the rainfall discharge in the period of time always enters the river, and the load of an external sewage treatment mechanism for treating sewage is reduced, because the water has the characteristic of natural evaporation in the period of time, the water level of the water collecting tank 6 gradually drops, and the evaporated water is discharged to the road through the exhaust pipe 8, so that the moisturizing effect is realized, when the water level drops below the height of the conductive post 14, because the conductive post 14 cannot conduct electricity, the electromagnetic valve 15 opens the second branch pipe 7, the water in the water collecting tank flows out from the second branch pipe 7, and meanwhile, the electromagnet 13 is attracted by the slide block 11 of the magnet structure in an uncharged state, the road is in the initial state again, and at the moment, after the road rains for a long time, more pollutants are accumulated again, so that the sewage disposal is required again, and the purpose of discharging the rainwater in different periods to different discharging places in different states is achieved.
