The bottom ends of the legs 5 are welded to the upper surface of the sealing plate, and the filter cartridge 4 is coaxially arranged with the embedded sleeve 2 .

[0035] like Figure 1 , 2 As shown, an outer flange 10 is provided at the top edge of the filter cartridge 4, and the outer flange 10 is fixedly connected to the annular waterproof plate 8 by bolts.

[0036] Example 3

[0037] like Figure 1 , 3As shown, the receiving tray 11 is horizontally arranged in the filter cartridge 4, and the side surface of the receiving tray 11 is slidably matched with the inner surface of the filter cartridge 4.

[0044] The use principle of this new model:

[0045] When the new type is used, rainwater enters the filter cartridge through the grate, and the debris in the rainwater is retained on the support tray, and the water is discharged through the filter holes of the filter cartridge, and then discharged into the connecting pipe through the drainage channel between the legs, and enters the underground drainage pipe 1 through the connecting pipe; as the amount of debris retention increases, the compression spring shortens, the support tray moves downward, and the filter holes exposed above the support tray continue to increase. While increasing the debris retention, the number of filter holes also increases synchronously, which can avoid the blockage problem caused by too much retention; when the debris retention exceeds a certain limit, the pressure block contacts the travel switch, and the alarm of the municipal drainage management center sounds an alarm, and the management personnel arrange staff to clean up the debris at the location of the embedded sleeve, without the need to manually check the amount of debris retention repeatedly, which is convenient for the overall management of the collection of debris. In the process of cleaning up the debris, the support tray slides upward under the elastic force of the compression spring due to the lighter load on the top, and scrapes the debris on the inner surface of the filter cartridge through the annular convex ridge 12, and dredges the filter holes through the annular brush to facilitate repeated use next time.
