[0002] At present, when rainwater is collected and used, the rainwater itself is clean, but during the rainfall process, automobile exhaust, industrial waste gas and particulate matter in the atmosphere will dissolve in it, and after falling to the ground, it will wash the ground, roads, etc., making the rainwater contain a large amount of pollutants such as sediment particles and floating objects. If the collected rainwater with a high degree of pollution is directly put into the rainwater reuse system without treatment, the treatment process will be complicated, the treatment facilities will increase, and the operating costs will increase. Therefore, when collecting rainwater, it is necessary to discard the rainwater with a high degree of pollution, so it is necessary to use a diversion well discard device.

[0003] At present, the addition of a flow abandonment device in the rainwater diversion well is mainly used in the diversion well for the early treatment of rainwater. It can automatically discharge and pre-filter the severely polluted rainwater in the early stage, and separate the early rainwater from the later rainwater, so as to abandon the early rainwater. However, the traditional rainwater abandonment device cannot automatically discharge according to the amount of rainfall, which makes the rainwater collection effect unsatisfactory and the corresponding sediment filtration efficiency is also relatively low.

One end of the linkage piece 3 is connected to the fixed housing 1 through a rotating shaft 8, and the other end of the linkage piece 3 is movably connected to the buoy 4.

[0025] Furthermore, a limiter is fixedly provided on the outside of the top of the discarded flow structure located in the first discarded flow chamber layer, and the limiter is in the shape of an "I" character so as to limit the installation position of the fixed shell 1 relative to the fixed plate A; a water outlet is opened at the bottom end of the discarded flow structure located in the second discarded flow chamber layer, and the water outlet is located below the water passage 5 to discharge water.

[0026] Furthermore, the float 4 is provided with a plurality of guide holes, which are elliptical, have a diameter of 7 to 8 cm, and a width of 0.10 to 0.15 times the diameter of the float 4.
