The rainwater in the rainwater ditch without mixing on the nearby ground can be introduced into the rainwater accommodating chamber 25 through the filter screen plate 7 on the side wall of the diversion box 1. A limiting rod 8 is also provided in the rainwater accommodating chamber 25, and a floating ball 10 is slidably provided on the outside of the limiting rod 8, and a connecting shaft 20 is integrally provided at the front and rear ends of the floating ball 10; Figure 2 , Figure 4 and Figure 5 As shown, a lower sliding rail 16 is provided at the lower end of one side of the float 10, and a limiting plate 15 is provided inside the lower sliding rail 16. The limiting plate 15 is located at the connecting pipe 14 between the diverter box 1 and the filter box 2, and a connecting rod 18 for pulling is provided between the limiting plate 15 and the float 10. When the rainwater entering the rainwater accommodating chamber 25 generates buoyancy on the float 10, the buoyancy pulls the limiting plate 15 through the connecting rod 18, so that the limiting plate 15 slides horizontally in the lower sliding rail 16, thereby opening the connecting pipe 14 between the diverter box 1 and the filter box 2. , so that rainwater flows into the storage box 3 through the filter box 2 for storage. A first drain pipe 4 is provided at the lower end of the storage box 3. The first drain pipe 4 is sealed and connected to the storage box 3. The rainwater collected in the storage box 3 can be actively taken out by opening the valve connected to the outside of the first drain pipe 4. When no rainwater flows into the rainwater accommodating chamber 25 in the dry season or the water level drops, the buoyancy disappears, the float 10 is reset, thereby pushing the limiting plate 15 to reset, thereby realizing the closure of the connecting pipe 14 between the diverter box 1 and the filter box 2, thereby protecting the components inside the filter box 2.

[0022] In this embodiment, if Figure 3 and Figure 5 As shown, a connecting ring 21 is arranged around the outside of the connecting shaft 20, and the connecting ring 21 is rotatably connected to the outside of the connecting shaft 20. A pair of connecting blocks 17 are arranged laterally on the upper end of the limiting plate 15, and the connecting block 17 is fixedly connected to the connecting ring 21 through a connecting rod 18, so that the floating ball 10 can pull the limiting plate 15 to move laterally through the connecting rod 18; wherein, one side of the two connecting blocks 17 is provided with an upper sliding rail 19, and the two upper sliding rails 19 are located at the upper end of the lower sliding rail 16, as shown in FIG.

[0023] In this embodiment, an activated carbon layer 11 is disposed transversely at the upper end of the filter box 2, a fine sand layer 12 is disposed transversely in the middle of the filter box 2, and a medium-coarse sand layer 13 is disposed transversely at the lower end of the filter box 2. Figure 3 As shown, the liquid discharged by the lateral movement of the limiting plate 15 will contact the activated carbon layer 11, the fine sand layer 12 and the medium-coarse sand layer 13 in the filter box 2 in sequence, and then the liquid can be filtered.

[0024] In this embodiment, the upper end of the float 10 is recessed with a groove 22. Figure 4 and Figure 5 As shown, a limiting plate 9 is welded to the upper end of the limiting rod 8 , and the outer portion of the limiting plate 9 is connected to the inner sliding groove of the groove 22 .

[0025] Working principle: When using the device to treat rainwater and sewage, the rainwater and sewage inlet 23 on the diversion box 1 can be directly connected to the corresponding rainwater and sewage mixing pipe, and the rainwater and sewage flow into the rainwater and sewage accommodating chamber 24 of the diversion box 1 through the rainwater and sewage inlet 23, and are directly discharged from the second drain pipe 5 on one side; and when it is necessary to store the rainwater after treatment, the rainwater in the rainwater ditch on the nearby ground without mixing can be introduced into the rainwater accommodating chamber 25 through the filter screen plate 7 on the side wall of the diversion box 1. As the water level in the rainwater accommodating chamber 25 rises, buoyancy is generated on the float 10, and the buoyancy will push the float 10 to move longitudinally upward under the restriction of the limiting rod 8. The longitudinal upward movement of the float 10 can also drive the connecting shaft 20 to move longitudinally, and the connecting shaft 20 can pull the connecting rod 1 through the connecting ring 21 8. The connecting rod 18 pulls the limiting plate 15 through the connecting block 17, so that the limiting plate 15 slides horizontally in the lower sliding rail 16. The horizontal movement of the limiting plate 15 can open the connecting pipe 14, so that rainwater can be discharged from the connecting pipe 14 into the filter box 2. The liquid entering the filter box 2 will pass through the activated carbon layer 11, the fine sand layer 12 and the medium-coarse sand layer 13 in turn for filtration, and then fall into the storage box 3 for storage to be used as a source of reclaimed water for irrigation or to be connected to the nearby green space infiltration well as a water source supplement. When no rainwater flows into the rainwater holding chamber 25 during the dry season or when the water level drops, the buoyancy disappears, and the float 10 is reset, thereby pushing the limiting plate 15 to reset, thereby closing the connecting pipe 14 between the diversion box 1 and the filter box 2, thereby protecting the components inside the filter box 2.
