When reaching the filter 402, the rainwater can be diverted by the guide plate 804, thereby extending the flow path of the rainwater on the filter 402, so that all parts of the filter 402 can be fully utilized. The size of the pressure plate 406 is consistent with the size of the top opening of the dirt collecting frame 403, and the dirt collecting frame 403 is slidably connected to the slider 803 through the guide groove 801. When the falling rainwater impacts the filter 402, the spring 802 will also make the movable frame 401 vibrate up and down under the limit of the guide groove 801 and the slider 803, further shaking off the impurities attached to the upper surface of the filter 402, which is beneficial to enhance the anti-blocking effect.

[0024] In summary, when using the rainwater sewage interception hanging basket with multiple filtration functions, first Figure 1 , Figure 2 and Figure 3 In the structure shown in the figure, the collected rainwater will enter the box body 1 from the water inlet 2 and fall on the top center of the movable frame 401. At this time, the guide plate 804 will guide the rainwater. Then, the rainwater can be filtered by the filter screen 402 in the process of continuing to flow downward, and the impurities are trapped above the filter screen 402. At the same time, since the filter screen 402 is inclined, it can slide into the dirt collecting frame 403 under the scouring of rainwater. Secondly, when the falling rainwater impacts the filter screen 402, the spring 802 will also make the movable frame 401 vibrate up and down under the limit of the guide groove 801 and the slider 803, further shaking off the impurities attached to the upper surface of the filter screen 402, and then, the electric push rod 405 can be started by the controller at a time to make the pressing plate 406 squeeze the impurities and filter water through the through hole 404, so as to increase the dirt holding capacity of the dirt collecting frame 403. Finally, the rainwater is discharged from the drain port 3 after being filtered by the non-woven filter plate 5 and the activated carbon filter plate 6.
