This can easily lead to the waste of clean rainwater or the entry of contaminated rainwater into the storage stage due to untimely operation. At the same time, impurities and pollutants carried by the initial rainwater enter subsequent stages, easily causing frequent clogging of filter cartridges. Furthermore, sedimentation tanks are often single-stage, and rainwater directly impacting the bottom of the tank can cause settled impurities to surge, mixing the upper clear water with the lower turbid water, resulting in a large amount of suspended impurities entering the filter box and accelerating filter cartridge wear. Therefore, a rainwater harvesting and production water control system is proposed to solve the problems mentioned above. Utility Model Content

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figures 1-6As shown, a rainwater recycling and production water co-control system includes a rainwater collection hopper 1, a main conveying pipe 2, and a diversion cylinder 3. One end of the main conveying pipe 2 is connected to the inlet end of the diversion cylinder 3, and the outlet end of the diversion cylinder 3 is connected to a first water supply pipe 4. The other end of the first water supply pipe 4 is connected to a guide channel 5, and the left end of the guide channel 5 is connected to a sedimentation tank 6. A filter box 7 is installed on the left side of the sedimentation tank 6, and the left end of the filter box 7 is connected to a third water supply pipe 26. The other end of the third water supply pipe 26 is connected to a water collection bucket 8. A hanging basket 9 is inserted into the upper end of the rainwater collection hopper 1, and several evenly distributed sieve holes 10 are opened through the bottom of the inner side of the hanging basket 9. The lower end of the rainwater collection hopper 1 is connected to a conveying branch pipe 11, and the other end of the conveying branch pipe 11 is connected to the interior of the main conveying pipe 2. A support rod 12 and a connecting rod 13 are installed inside the diversion cylinder 3. A float 14 is fixedly connected between the support rods 12. A partition 16 is fixedly connected inside the diversion cylinder 3. A diversion hole 17 is opened through the upper end of the partition 16. A sealing piece 15 is fixedly connected through the lower end of the connecting rod 13 through the diversion hole 17. A first support plate 18 is fixedly connected above the partition 16 on the inner side of the diversion cylinder 3. A filter screen 19 is fixedly connected between the first support plate 18 and the partition 16. Three overflow holes 20 are opened through the left end of the sedimentation tank 6. An overflow pipe 21 is connected to the left end of the sedimentation tank 6 and the corresponding position of the three overflow holes 20. The other end of the overflow pipe 21 is connected to a solenoid valve 2101. The other end of the solenoid valve 2101 is connected to a second water supply pipe 2102. The other end of the second water supply pipe 2102 is connected to the right end of the filter box 7. A filter element 25 is installed inside the filter box 7.

[0015] Furthermore, several rainwater collection hoppers 1 are provided and installed on the top of the building via brackets to expand the rainwater receiving area. The screen holes 10 on the hanging basket 9 are used to initially filter large impurities in the rainwater, such as fallen leaves and branches, to prevent impurities from clogging the subsequent conveying pipes. The hanging basket 9 can be pulled upwards to separate from the rainwater collection hopper 1 for easy cleaning and maintenance. The rainwater collected by several rainwater collection hoppers 1 is collected through the conveying branch pipe 11 and then converged into the conveying main pipe 2 for unified conveying to the diversion cylinder 3.

[0016] Furthermore, a second support plate 27 is fixedly connected between the first support plate 18 and the inner wall of the diversion tube 3, and a support rod 12 is slidably connected inside the second support plate 27. A limit block 28 is fixedly connected above the second support plate 27 on the outer surface of the support rod 12.

[0017] Furthermore, the lower end of the diversion tube 3 is connected to the municipal sewage network through a municipal sewage pipe for discharging initial rainwater. The baffle 16 is used to separate the initial rainwater from the clean rainwater. The float 14 moves up and down with the rise and fall of the water level in the diversion tube 3. The support rod 12 provides vertical guidance for the float 14 and the connecting rod 13 to ensure that the float 14 does not deviate when the water level rises and falls. The second support plate 27 supports and limits the support rod 12, so that it can only move in the vertical direction, ensuring that the rising and falling trajectory of the float 14 is stable. The limiting block 28 is used to limit the maximum descent distance of the support rod 12 to prevent the float 14 from moving too far down when the water level falls. The connecting rod 13 is used to transmit the rising and falling action of the float 14, driving the sealing plate 15 to move synchronously, realizing the opening and closing of the diversion hole 17.

[0018] Furthermore, the water level in the diversion tube 3 will rise as the rainfall time increases. In the initial stage of rainfall, there are more impurities in the rainwater, and the water level in the diversion tube 3 is also low. The diversion hole 17 is in the open state, and the initial rainwater containing more impurities will enter the lower cavity of the diversion tube 3 through the diversion hole 17 and be discharged into the municipal pipe network without being recycled. As the rainfall continues, the cleanliness of the rainwater gradually increases, and the water level in the diversion tube 3 gradually rises, causing the float ball 14 to drive the sealing plate 15 to block the diversion hole 17. At this time, the rainwater enters the first water supply pipe 4 through the filter screen 19, and then is transported to the sedimentation tank 6 through the diversion channel 5.

[0019] Furthermore, the sedimentation tank 6 allows suspended impurities in the rainwater to naturally settle to the bottom of the tank, achieving preliminary purification of the rainwater. The guide channel 5 is trapezoidal, with the side with the larger opening facing the sedimentation tank 6, which is used to guide the rainwater transported by the first water pipe 4 to flow smoothly into the sedimentation tank 6, avoiding the rainwater directly impacting the bottom of the sedimentation tank 6 and causing the settled impurities to surge. The overflow hole 20 is used to discharge the clean rainwater in the upper layer of the sedimentation tank 6.

[0020] Furthermore, the distance between the three overflow holes 20 and the bottom of the inner side of the sedimentation tank 6 increases sequentially from front to back. The three overflow holes 20 are used to achieve graded discharge of rainwater according to the degree of sedimentation. At the beginning of rainfall, the water level in the sedimentation tank 6 is low. At this time, only the solenoid valve 2101 corresponding to the lowest overflow hole 20 is opened to discharge the clearer rainwater in the upper layer. As the water level rises, the solenoid valves 2101 corresponding to the higher overflow holes 20 are opened sequentially, and the solenoid valves 2101 corresponding to the lower overflow holes 20 are closed to ensure that the clear water in the upper layer at different depths can be discharged. The clean rainwater discharged through the overflow holes 20 will flow into the filter box 7 through the overflow pipe 21 and the second water supply pipe 2102. Furthermore, a first slot 22 is provided through the upper end of the filter box 7. A fixing frame 23 is inserted into the first slot 22. A second slot 24 is provided at the front end of the fixing frame 23. The filter element 25 is inserted into the second slot 24. The filter element 25 is used to deeply purify the rainwater transported by the overflow pipe 21 and the second water supply pipe 2102, removing fine suspended particles, odors and some microorganisms that remain after sedimentation, so that the rainwater quality meets the requirements for production water. The fixing frame 23 is used to fix the filter element 25. The insertion and connection between the filter element 25 and the second slot 24 facilitates the removal of the filter element 25. The first slot 22 provides an insertion and removal channel for the fixing frame 23, making it easy to remove the fixing frame 23 from the filter box 7.

[0021] Furthermore, a handle 29 is fixedly connected to the upper end of the fixed frame 23. The handle 29 provides a gripping point for inserting or removing the fixed frame 23, making it convenient for operators to quickly remove or insert the fixed frame 23 to replace the filter element 25.

[0022] Furthermore, the rainwater filtered by the filter box 7 flows into the water collection tank 8 through the third water pipe 26 for storage, and the rainwater in the tank can be pumped out for use.

[0023] Furthermore, the water level in sedimentation tank 6 is monitored in real time by an external water level sensor.

[0024] Working principle: During rainfall, rainwater from the top of the building falls into the rainwater collection hopper 1. After being filtered by the screen holes 10 of the hanging basket 9 to remove large impurities, it is collected through the conveying branch pipe 11 and sent to the conveying main pipe 2, flowing into the upper cavity of the diversion cylinder 3. In the initial rainfall stage, the water level in the diversion cylinder 3 is low, the float 14 sinks, and the connecting rod 13 drives the sealing plate 15 away from the diversion hole 17. The initial rainwater enters the lower cavity of the diversion cylinder 3 through the diversion hole 17 and is eventually discharged into the municipal sewage network. In the middle and later stages of rainfall, the cleanliness of the rainwater increases, and the water level in the diversion cylinder 3 continues to rise. The float 14 rises with the water level, and the connecting rod 13 drives the sealing plate 15 to rise and press against the diversion hole 17. Clean rainwater cannot enter the lower cavity and can only flow through the first water conveyance pipe 4 and the diversion channel. 5. The clean rainwater flows into the sedimentation tank 6. After entering the sedimentation tank 6, the suspended impurities naturally settle to the bottom of the tank, and the water level in the sedimentation tank 6 gradually rises. Initially, the water level only reaches the lowest overflow hole 20. At this time, the corresponding solenoid valve 2101 opens, and the clearer rainwater in the upper layer flows into the filter box 7 through the lowest overflow pipe 21 and the second water supply pipe 2102. As the water level rises, the solenoid valve 2101 corresponding to the higher overflow hole 20 opens simultaneously, while the solenoid valve 2101 corresponding to the lower overflow hole 20 closes, ensuring that the upper layer of clean water at different depths can be discharged. The settled clean water enters the filter box 7, passes through the filter element 25, and after removing fine impurities and odors, it flows into the water collection tank 8 for storage through the third water supply pipe 26.
