[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, and transports them through different pipes for discharge or subsequent treatment. In municipal rainwater and sewage drainage, with the development of urbanization, in line with the concept of environmental protection, the drainage pipes are divided into two groups, one for rainwater flow and discharge into the river, and the other for sewage flow and send the sewage to the sewage treatment plant for treatment. Rainwater is directly discharged into the river through the rainwater pipe network, and sewage is collected through the sewage pipe network and sent to the sewage treatment plant for treatment to avoid sewage directly entering the river and causing pollution. In addition, the collection, utilization and centralized management and discharge of rainwater can reduce the impact of water volume on sewage treatment plants and ensure the treatment efficiency of sewage treatment plants.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0025] See also Figure 1-3 As shown, the utility model is a diversion drainage network for controlling polluted rainwater and rainwater, including a diversion shell 1 and an inlet pipe 2. The lower end of the inlet pipe 2 passes through the top surface of the diversion shell 1 to the upper half of the inner cavity of the diversion shell 1. Two parallel guide clamps 3 are fixed to the middle of the left side of the inner cavity of the diversion shell 1. A closing plate 4 that slides left and right is installed between the two guide clamps 3. A semicircular groove is opened at the right end of the closing plate 4. A guide half-pipe 6 is fixed to the inner wall of the semicircular groove, and the inner and outer diameters of the guide half-pipe 6 are the same as the inner and outer diameters of the bottom of the water inlet pipe 2. A water retaining plate 8 is fixed to the middle of the right side of the inner cavity of the diversion shell 1, and the upper surface of the water retaining plate 8 is flush with the upper surface of the closing plate 4. A semicircular sealing plate 9 that cooperates with the inner wall of the guide half-pipe 6 is fixed to the left end of the water retaining plate 8. The guide splint 3, the closing plate 4, the water retaining plate 8 and the semicircular closing plate 9 divide the inner cavity of the diversion shell 1 into an upper diversion cavity and a lower diversion cavity, and the upper diversion cavity and the lower diversion cavity are respectively penetrated and fixedly connected with a rainwater pipe 7 and a sewage pipe 10. A sewage turbidity meter 11 is installed through the lower end of the water inlet pipe 2 to measure the turbidity of the rainwater currently flowing through the water inlet pipe 2. The sewage turbidity meter 11 is a MIK-PTU200 online turbidity detector. A control box 5 for controlling the left and right sliding of the closing plate 4 is installed on the left outer wall of the diversion shell 1. Among them, an electric telescopic rod 12 and a processor are arranged in the control box 5. The telescopic end of the electric telescopic rod 12 passes through the outer wall of the diversion shell 1 and is connected to the left end of the closing plate 4 to control the sliding of the closing plate 4. The processor is connected to the sewage turbidity meter 11 and the electric telescopic rod 12. The sewage turbidity meter 11 measures the turbidity of the rainwater in the current water inlet pipe 2 and transmits the information to the processor. After analysis by the processor, the electric telescopic rod 12 is controlled to realize the sliding of the closing plate 4.
[0026] When the sewage turbidity meter 11 detects that the turbidity reaches the level of polluted rainwater, the processor controls the electric telescopic rod 12 to retract and drive the closing plate 4 away from the water retaining plate 8, and a downstream channel is formed between the closing plate 4 and the water retaining plate 8. The sewage from the water inlet pipe 2 directly flows to the lower diversion chamber below, and the water in the upper diversion chamber also flows to the lower diversion chamber. During the flow, the upper diversion chamber is flushed and cleaned to ensure the cleanliness of the upper diversion chamber, and the polluted rainwater is discharged from the sewage pipe 10 into the sewage network. When the sewage turbidity meter 11 detects that the turbidity does not reach the level of polluted rainwater, the processor controls the electric telescopic rod 12 to extend and drive the closing plate 4 to move close to the water retaining plate 8, and the upper diversion chamber is completely isolated from the lower diversion chamber. The rainwater distributed by the water inlet pipe 2 is discharged from the rainwater pipe 7 of the upper diversion chamber to the rainwater network. The device measures the current water quality through the sewage turbidity meter 11, and selects the current rainwater to be discharged from the rainwater pipe 7 of the upper diversion chamber or the sewage pipe 10 of the lower diversion chamber to the corresponding pipe network according to the actual situation. The whole process does not require manual operation, which is more convenient in actual use. The overall device effectively avoids cross contamination when discharging polluted rainwater, effectively prevents sewage from flowing into the river to pollute the environment, or prevents rainwater with low turbidity from entering the sewage treatment plant, thereby increasing the sewage treatment capacity of the sewage treatment plant.
[0027] In order to prevent the clear rainwater in the water inlet pipe 2 from flowing out directly from the lower end and causing a large impact on the closing plate 4, affecting the sealing between the closing plate 4 and the guide clamping plate 3 and the water retaining plate 8, a rainwater diversion device is installed between the water inlet pipe 2 and the closing plate 4. The rainwater diversion device specifically includes a gate plate 13, a pull rope 14, a fixed pulley 15, and a branch pipe 21 that passes through and is fixed to the outer wall of the lower end of the water inlet pipe 2. A gate 22 that cooperates with the gate plate 13 is opened on the branch pipe 21. The fixed pulley 15 is fixed to the top surface of the diversion shell 1. The pull rope 14 passes around the fixed pulley 15, one end of which is connected and fixed to the upper end of the gate plate 13, and the other end is connected and fixed to the upper surface of the closing plate 4. When the sewage turbidity meter 11 detects that the turbidity does not reach the level of polluted rainwater, the processor controls the electric telescopic rod 12 to extend and drive the closing plate 4 to move close to the water retaining plate 8, the pull rope 14 drives the gate plate 13 upward along the gate 22, the branch pipe 21 is opened, and the rainwater enters the upper diversion cavity from the branch pipe 21, and the rainwater distributed by the water inlet pipe 2 is discharged from the rainwater pipe 7 of the upper diversion cavity to the rainwater pipe network. When the sewage turbidity meter 11 detects that the turbidity reaches the level of polluted rainwater, the processor controls the electric telescopic rod 12 to retract and drive the closing plate 4 away from the water retaining plate 8, the pull rope 14 changes from a tensioned state to a relaxed state, the gate plate 13 moves downward along the gate 22 to close the branch pipe 21, and the water in the water inlet pipe 2 is discharged from the lower end. In addition, in order to prevent the water flowing in the water inlet pipe 2 from impacting the closing plate 4, a blocking plate 16 is fixed on the surface of the closing plate 4. When the closing plate 4 contacts and seals with the water retaining plate 8, the blocking plate 16 is located directly below the water inlet pipe 2.
[0028] In order to directly impact the bottom of the diversion shell 1 with a high drop of water discharged from the water inlet pipe 2 , a spoiler inclined plate 17 is fixed to the lower diversion chamber directly below the water inlet pipe 2 and the water baffle 8 .
