The sludge scraper 20 is used to clean the inner bottom wall of the water storage tank 2.

[0041] The impurity collection pool 12 is located on the outer wall of the water storage pool 2 and is used to collect impurities that are swept away from the surface of the primary filter plate 6 by the scraper 11.

[0042] like Figure 3 and Figure 4As shown, a sludge scraper 20 is provided. When the scraper 11 is driven to move along the upper surface of the primary filter plate 6, the sludge scraper 20 is driven to move along the bottom wall of the water storage tank 2 to clean the sludge deposited in the water storage tank 2. The water storage tank 2 is provided with a drain outlet and a drain valve to facilitate the discharge of sludge from the water storage tank 2. The impurity collection tank 12 is located below the side of the primary filter plate 6 that extends out of the water storage tank 2, so as to facilitate the collection of impurities cleaned by the scraper 11 from the surface of the primary filter plate 6, and to facilitate the user to centrally process the impurities.

[0043] In this embodiment, the secondary filtration mechanism includes a filter box 3, a secondary filter plate 21, and a precipitant addition pipe 32.

Of course, the primary filter plate 6 also has several filter holes. The diameter of the filter holes opened on the primary filter plate 6 and the secondary filter plate 21 is set according to the usage requirements.

[0047] In this embodiment, the secondary filtration mechanism further includes a plurality of stirring blades 23, which are disposed on the rotating column 22 and located below the secondary filter plate 21.

[0048] like Figure 3 As shown, the stirring blade 23 is positioned below the secondary filter plate 21, so that when the rotating column 22 rotates, it can mix and stir the precipitant with the rainwater, causing the fine suspended matter in the water to quickly flocculate and settle.

[0049] In this embodiment, the disinfection mechanism includes a disinfection box 4 and a disinfectant addition pipe 31. The disinfection box 4 is fixedly installed on the base plate 1. The disinfection box 4 is connected to the filter box 3 through a connecting pipe II.

The driving pulley 14 transmits power to the driven pulley 15 via the transmission belt. The cleaning assembly II is located inside the disinfection box 4 and is fixedly connected to the rotating rod 25, and is used to clean the side walls of the disinfection box 4.

[0052] like Figure 3As shown, the bottom of the rotating rod 25 is rotatably mounted on the bottom wall of the disinfection box 4 via a bearing. The drive motor II 13 transmits power to the driven pulley 15 via the drive belt and the transmission belt. The driven pulley 15 transmits power to the rotating rod 25, thereby driving the rotating rod 25 to rotate. The rotating rod 25 drives the cleaning assembly II to clean the side wall of the disinfection box 4, which can remove the dirt attached to the side wall.

[0053] In this embodiment, the cleaning component II includes a connecting pipe I 27, a connecting pipe II 29, an elastic element 30, and a cleaning brush 26. The connecting pipe I 27 is fixedly disposed on the rotating rod 25. One end of the connecting pipe II 29 is inserted into the connecting pipe I 27, and the other end of the connecting pipe II 29 is fixedly connected to the cleaning brush 26.

The cleaning brush 26 abuts against the inner wall of the disinfection box 4 for cleaning the inner wall of the disinfection box 4.

[0054] like Figure 6 As shown, the driven pulley 15 is located at the end of the rotating rod 25, and the elastic element 30 is a spring. The elastic element 30 applies force to the connecting pipe II 29 and the cleaning brush 26, so that the cleaning brush 26 always rotates in contact with the inner wall of the disinfection box 4 to remove the dirt attached to the inner wall.
