[0024] like Figure 1 , Figure 2 As shown, the rainwater collection and treatment system of this embodiment includes a waste flow well 10, a sedimentation tank 20, a filter tank 30, a clean water tank 40 and a second water pump 50.

[0025] The abandoned flow well 10 is connected with an inlet pipe 11, an abandoned flow pipe 12 and an outlet pipe 13. The inlet pipe 11 and the outlet pipe 13 are both connected to the upper side wall of the abandoned flow well 10, and the abandoned flow pipe 12 is connected to the lower side wall of the abandoned flow well 10. The abandoned flow pipe 12 is close to the bottom of the abandoned flow well 10. The inlet pipe 11 is used to send the collected roof rainwater and road infiltration rainwater into the abandoned flow well 10. The abandoned flow well 10 is provided with a pipe body 14, a floating ball 15, a rod body 16 and a plate body 17. The pipe body 14 is vertically arranged, one end of the abandoned flow pipe 12 extends into the abandoned flow well 10, and the lower end of the pipe body 14 is connected to the abandoned flow pipe 1 2 is connected, the upper end surface of the tube body 14 is in an upwardly convex spherical shape, and a plurality of through holes 141 are arranged on the upper end surface of the tube body 14. The rod body 16 is vertically arranged and can move up and down through the upper end surface of the tube body 14. The floating ball 15 is fixed to the upper end of the rod body 16, and the plate body 17 is fixed to the lower end of the rod body 16. The plate body 17 is located in the tube body 14, and the shape of the plate body 17 is consistent with the upper end surface of the tube body 14. When the floating ball 15 floats up, it can drive the plate body 17 to move upward along the tube body 14. When the floating ball 15 floats up to a certain height, the plate body 17 can cover all the through holes 141 on the upper end surface of the tube body 14.

[0026] In this way, when the dirty rainwater enters the waste flow well 10 in the initial stage, since the rainfall has just begun at this time, the amount of water flowing into the waste flow well 10 is not large, so that the water level in the waste flow well 10 is not high. At this time, the water in the waste flow well 10 can flow into the pipe body 14 through the multiple through holes 141 on the upper end surface of the pipe body 14, and then be discharged through the waste flow pipe 12 for waste flow; and after a certain period of subsequent rainfall, the rainwater flowing into the waste flow well 10 becomes relatively clean, and at this time the water level in the waste flow well 10 gradually rises, so that the float 15 gradually floats up, and the float 15 drives the plate body 17 to move up through the rod body 16, so that the plate body 17 is attached to the upper end surface of the pipe body 14, thereby covering the through holes 141 on the upper end surface of the pipe body 14, and the rainwater in the waste flow well 10 cannot enter the waste flow pipe 12 for waste flow, and the rainwater in the waste flow well 10 can enter the sedimentation tank 20 through the outlet pipe 13.

[0027] The sedimentation tank 20 is connected to the water outlet pipe 13 . The water outlet pipe 13 is used to send the water in the waste well 10 into the sedimentation tank 20 . A first water pump 21 is provided at the bottom of the sedimentation tank 20 .

[0028] The filter tank 30 is connected to the water outlet end of the first water pump 21 through a first pipeline 22 . The first water pump 21 is used to deliver the precipitated water in the sedimentation tank 20 to the water inlet of the filter tank 30 .

[0029] The clean water tank 40 is connected to the water outlet of the filter tank 30 through the second pipeline 31 . The water filtered by the filter tank 30 is sent into the clean water tank 40 through the second pipeline 31 . The clean water tank 40 is used to store the water filtered by the filter tank 30 .

[0030] The second water pump 50 is used to transport the water in the clean water tank 40 to the outside for use in landscaping or washing hands in the bathroom.

[0031] The bottom surface 24 of the sedimentation tank 20 is inclined, and a lower recess 23 is provided at the lowest point of the bottom surface 24 of the sedimentation tank 20. The first water pump 21 is arranged in the lower recess 23. In this way, the first water pump 21 can transport as much water in the sedimentation tank 20 as possible to the filter tank 30 to avoid waste caused by excessive water remaining in the sedimentation tank 20.

[0032] The top of the waste flow well 10 is open, and a cover plate 18 is closed on the top of the waste flow well 10. A plurality of water holes 181 are arranged on the cover plate 18. In this way, when it rains, rainwater can also enter the waste flow well 10 through the water holes 181 on the cover plate 18, so that the rainwater collection efficiency is higher.

[0033] A driving rod 19, a baffle 194, a guide seat 193 and a compression spring 192 are also provided in the abandoned flow well 10. The guide seat 193 is fixedly installed on the inner wall of the abandoned flow well 10. The wire seat 193 is located directly above the water inlet pipe 11. The driving rod 19 can vertically slide through the guide seat 193, so that the driving rod 19 can slide vertically up and down. The baffle 194 is connected to the lower end of the driving rod 19, and the baffle 194 is in contact with the inner wall of the abandoned flow well 10. The upper end of the driving rod 19 is provided with a radially protruding end plate 191. The compression spring 192 is sleeved on the driving rod 19, and the lower end of the compression spring 192 is against the upper surface of the guide seat 193, and the upper end of the compression spring 192 is against the lower surface of the end plate 191.

[0034] When the cover plate 18 is closed on the top of the waste flow well 10, the cover plate 18 abuts against the end plate 191. At this time, the driving rod 19 is pressed down by the cover plate 18, the baffle plate 194 is staggered from the water inlet pipe 11, and the compression spring 192 is compressed. At this time, the baffle plate 194 will not block the water inlet pipe 11 from delivering water to the waste flow well 10.

[0035] When the cover plate 18 is detached from the top of the waste flow well 10, the compression spring 192 is expanded and reset to drive the driving rod 19 to move downward until the baffle plate 194 abuts against the lower surface of the guide seat 193. At this time, the baffle plate 194 blocks the end of the water inlet pipe 11. In this way, the operator can avoid the situation where water enters the water inlet pipe 11 when opening the cover plate 18 to clean the inside of the waste flow well 10, thereby avoiding the situation where water enters the water inlet pipe 11 and impacts the operator.

[0036] The connection point between the water inlet pipe 11 and the waste flow well 10 is higher than the connection point between the water outlet pipe 13 and the waste flow well 10 .
