A sealing gasket 20, which is a corrosion-resistant rubber sealing ring, is provided at the connection between the valve body connecting sleeve 9 and the valve body 16. A signal conduit 7 is provided inside the valve body connecting sleeve 9. One end of the signal conduit 7 passes through the inspection well box 2. A rainwater and foreign matter grille 8 is provided at the upper end of the valve body 16. The connecting sleeve 9 passes through the rainwater and foreign matter grid 8. A lifting ring 10 is fixedly connected to the upper end of the rainwater and foreign matter grid 8. Water inlet holes 14 are opened on both sides of the upper end of the valve body 16. A valve body slot 17 is opened on the outer side of the upper end of the valve body 16. A bottom mesh cover 15 is connected to the valve body slot 17. A hydraulic push rod 11 is connected to the water storage tank 4. A hydraulic push rod clip 19 is connected to the output end of the hydraulic push rod 11. A connecting rod valve 18 is connected to the hydraulic push rod clip 19. The connecting rod valve 18 cooperates with the two water inlet holes 14. A water pump 13 is connected to the bottom mesh cover 15. A connecting pipe 6 is connected to the outlet end of the water pump 13. The connecting pipe 6 passes through the valve body connecting sleeve 9 and the inspection well box 2 in sequence. A liquid level sensor 12 is connected to the connecting pipe 6.

[0023] Work process:

[0024] When it rains, rainwater enters the three-way rainwater pipe 3 through the inspection well box 2 and gathers at the upper end of the valve body 16. The rain sensor transmits the signal to the external control box. When the rainfall reaches the preset value, the control box starts the hydraulic push rod 11. The hydraulic push rod 11 drives the hydraulic push rod clip 19 to move upward, thereby pushing the connecting rod valve 18 to move upward. After the connecting rod valve 18 moves to a certain position, it cooperates with the water inlet 14 to seal the water inlet 14. At this time, the rainwater is discharged directly through the three-way rainwater pipe 3. The device does not collect or intercept water. Through the linkage control of the rain sensor and the hydraulic push rod, the water inlet 14 is automatically closed at the beginning of the rainfall, and the rainwater is discharged directly into the municipal pipe network, avoiding the entry of initial pollutants such as oil and heavy metals carried by surface runoff into the water storage system, and reducing the load on sewage treatment from the source.

[0025] When the rainfall stops, the rain sensor sends a signal to the control box, which then controls the hydraulic push rod 11 to start working. The hydraulic push rod 11 drives the hydraulic push rod retainer 19 to move downward, thereby pulling the connecting rod valve 18 downward. After the connecting rod valve 18 moves to a certain position, it separates from the water inlet 14, and the water inlet 14 opens. The water in the three-way rainwater pipe 3 enters the water storage tank 4 after being filtered by the rainwater foreign matter grille 8. The water in the water storage tank 4 is discharged through the sewage pipe connection port 5. When the water level in the water storage tank 4 exceeds the set value of the liquid level sensor 12, the liquid level sensor 12 sends a signal to the control box, which starts the water pump 13 to pump water. The water pump 13 sends the sewage into the sewage pipe network through the connecting pipe 6. The cooperation between the liquid level sensor 12 and the water pump 13 can dynamically monitor the capacity of the water storage tank 4. When the limit is exceeded, drainage is automatically started to avoid system paralysis due to the overflow of the water storage tank, and at the same time reduce the instantaneous drainage pressure of the municipal pipe network during heavy rain.

[0026] The automated control of the control box reduces the need for manual intervention. The mechanical structure of the linkage valve 18 and the hydraulic push rod clip 19 has high reliability. The rainwater debris grille 8's filtration and segmented drainage design effectively prevents leaves, garbage and other debris from entering the sewage pipe network, reducing the risk of pipe blockage. The rainwater debris grille 8 can be cleaned regularly, has a low maintenance frequency, and is easy to install and maintain.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
