Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage treatment technology, specifically to a smart rainwater and sewage switching system. Background Technology

[0002] Currently, urban stormwater and sewage are handled using either combined or separate sewer systems. Combined sewer systems reduce the cost of urban pipe network construction but increase the pressure on urban sewage treatment plants, as well as the investment and operating costs of sewage treatment facilities. Separate sewer systems, while reducing the pressure on urban sewage treatment plants, require significant investment in pipe network construction, and the initial stormwater carries a large amount of silt and debris, which pollutes rivers after entering water bodies. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a smart switching system for rainwater and sewage, which addresses the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A smart rainwater and sewage switching system includes a rainwater and sewage mixing well. A sewage inlet pipe and a rainwater inlet pipe are installed on one side of the mixing well, arranged side-by-side or parallel. A shut-off device is installed at the inlet of each pipe. A rainwater and sewage discharge pipe and a rainwater discharge pipe are installed on the other side of the mixing well, arranged side-by-side or parallel. A shut-off device is also installed at the inlet of each pipe. The sewage inlet pipe and the rainwater and sewage discharge pipe are connected side-by-side via a bypass pipe.

[0006] Furthermore, the interruption device is a gate.

[0007] Furthermore, the gate includes a gate panel, a gate frame, and a hoist. The hoist is installed at the opening of the stormwater and sewage mixing well, and a screw rod passes through the middle of the hoist. The gate frame is installed at the pipe opening, and guide rails are installed on both sides of the gate frame. The gate panel slides between the guide rails, and the upper end of the gate panel is connected to the bottom of the screw rod. A wedge seat is installed on the guide rail, and an upper wedge block is installed at the bottom of the wedge seat. A lower wedge block is installed on the side of the gate panel, and a sealing strip is installed on the side of the gate frame.

[0008] Furthermore, the switching device employs an electrically controlled valve.

[0009] Furthermore, a valve well is connected to the side of the rainwater and sewage mixing well, and an electric control valve is installed inside the valve well.

[0010] Furthermore, a bypass control valve is installed on the bypass pipe, and a bypass valve well is connected to one side of the rainwater and sewage mixing well. The bypass control valve is located inside the bypass valve well.

[0011] Compared with existing technologies, this utility model's intelligent rainwater and sewage switching system solves the drawbacks of combined and separate rainwater and sewage systems, particularly addressing the pollution problem of initial rainwater runoff from separate rainwater and sewage pipe networks on river water bodies. It connects initial rainwater containing silt and debris to the sewage pipe network and, through appropriate switching methods, achieves the collection and treatment of this initial rainwater. Simultaneously, it solves the problem of treating later rainwater in combined sewer systems by directly discharging middle and later rainwater with lower silt and debris content into rivers through diversion, thereby reducing the pressure on sewage treatment plants, lowering their treatment costs, and reducing urban pipe network construction costs.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0023] like Figures 1-9 As shown, a smart rainwater and sewage switching system includes a rainwater and sewage mixing well 1. A sewage inlet pipe 2 and a rainwater inlet pipe 3 are installed on one side of the rainwater and sewage mixing well 1, arranged side-by-side or parallel. A shut-off device is installed at the inlet of each pipe. A rainwater and sewage discharge pipe 4 and a rainwater discharge pipe 5 are installed on the other side of the rainwater and sewage mixing well 1, arranged side-by-side or parallel. A shut-off device is also installed at the inlet of each pipe. The sewage inlet pipe 2 and the rainwater and sewage discharge pipe 4 are connected side-by-side by a bypass pipe 6. A bypass pipe control valve 7 is installed on the bypass pipe 6. A bypass pipe valve well 8 is connected to one side of the rainwater and sewage mixing well 1, and the bypass pipe control valve 7 is located inside the bypass pipe valve well 8.

[0024] In this invention, the switching device controls the opening and closing of the pipe openings. At the beginning of heavy rain, the urban pipe network has a large flow rate containing a large amount of silt and debris. The switching devices at the openings of the sewage inlet pipe 2, rainwater inlet pipe 3, and rainwater and sewage discharge pipe 4 are opened, while the switching device at the opening of the rainwater discharge pipe 5 is closed. Sewage and rainwater mixed with silt and debris enter the sewage treatment plant from the rainwater and sewage discharge pipe 4. After a period of time, the rain weakens and the debris is greatly reduced. The switching devices at the openings of the sewage inlet pipe 2 and rainwater and sewage discharge pipe 4 are closed, and the bypass pipe control valve 7 is opened. Sewage enters the rainwater and sewage discharge pipe 4 from the bypass pipe 6, while the switching devices at the openings of the rainwater inlet pipe 3 and rainwater discharge pipe 5 are opened. The rainwater containing silt and less debris in the middle and later stages is discharged into the river through the rainwater discharge pipe 5 to reduce the pressure on the sewage treatment plant.

[0025] Example 1

[0026] like Figures 1-6As shown, in this embodiment, the sewage inlet pipe 2 and the rainwater inlet pipe 3 are arranged side by side, and the rainwater and sewage discharge pipes 4 and 5 are arranged side by side. The switching device is a gate 9, which includes a gate panel 911, a gate frame 912, and a hoist 913. The hoist 913 is installed at the opening of the rainwater and sewage mixing well 1. A screw 914 passes through the middle of the hoist 913, and the hoist 913 controls the screw to move up and down. The gate frame 912 is installed at each pipe opening. A guide rail 915 is installed on each side of the gate frame 912. The gate panel 911 slides between the guide rails 915. The upper end of the gate panel 911 is connected to the bottom of the screw 914. Guide grooves 916 are machined on the side of the guide rails. The side of the panel 911 is machined with a guide edge 917, which slides within the guide groove 916. The upper end of the door panel 911 is machined with a connecting seat, and a pin 918 passes through the connecting seat. The bottom of the screw 914 is connected to the pin 918, and a cotter pin is provided on the side of the pin 918. The guide rail 915 is mounted with a wedge seat 919 on the door frame 912. An upper wedge block 920 is mounted on the bottom of the wedge seat 919, and a lower wedge block 921 is mounted on the side of the door panel 911. A sealing strip 922 is mounted on the side of the door frame 912. When the door panel 911 closes the pipe opening, the upper wedge block 920 on the wedge seat 919 engages with the wedge surface of the lower wedge block 921, and the door panel 911 presses against the sealing strip 922 to seal the pipe opening.

[0027] In this embodiment, the hoist 913 controls the gate plate 911 to open and close the pipe openings. In the early stage of heavy rain, the hoist 913 controls the gate plate 911 to open the sewage inlet pipe 2, the rainwater inlet pipe 3, and the rainwater and sewage discharge pipe 4, and close the rainwater discharge pipe 5, so that sewage and rainwater can enter the rainwater and sewage discharge pipe 4. In the later stage of heavy rain, the hoist 913 controls the gate plate 911 to close the sewage inlet pipe 2 and the rainwater and sewage discharge pipe 4, and open the rainwater inlet pipe 3 and the rainwater discharge pipe 5 to discharge the rainwater into the river.

[0029] like Figure 7 As shown, in this embodiment, the sewage inlet pipe 2 and the rainwater inlet pipe 3 are arranged side by side, and the rainwater and sewage discharge pipe 4 and the rainwater discharge pipe 5 are arranged side by side. The switching device adopts an electric control valve 10, which is installed on each pipe opening. The side of the rainwater and sewage mixing well 1 is connected to a valve well 11, and the electric control valve 10 is installed in the valve well 11. The opening or closing of each pipe opening is controlled by the electric control valve 10.

[0031] like Figure 8As shown, in this embodiment, the sewage inlet pipe 2 and the rainwater inlet pipe 3 are arranged side by side, and the rainwater and sewage discharge pipe 4 and the rainwater discharge pipe 5 are arranged side by side.

The side of the rainwater and sewage mixing well 1 is connected to a valve well 11, and the electric control valve 10 is installed in the valve well 11. The opening or closing of each pipe opening is controlled by the electric control valve 10.
