Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The embodiment of the utility model relates to a rainwater drainage system, as shown in figure 1, comprising a header pipe 1, a sewage pipe 3 and a river pipe 2 are arranged at the downstream of the header pipe 1, a sewage control valve 5 and a water quality detector 6 are arranged on the sewage pipe 3, and a river control valve 4 and a water flow sensor 11 are arranged on the river pipe 2; the sewage control valve 5, the water quality detector 6, the river control valve 4 and the water flow sensor 11 are all connected with a controller 8; and the controller 8 controls the sewage control valve 5 and the river control valve 4 to be opened or closed according to the detection results of the water quality detector 6 and the water flow sensor 11.
Therefore, in the embodiment, the rainwater can be divided into two paths through the header pipe 1, wherein one path is the river water pipe 2, and the other path is the sewage pipe 3; the river pipe 2 discharges rainwater into natural waters such as a river channel, and the sewage pipe 3 discharges the rainwater to a sewage treatment plant. In general, the river control valve 4 in the present embodiment is normally closed, and the sewage control valve 5 is normally open. The controller 7 controls the river control valve 4 and the sewage control valve 5 to be opened and closed according to the detection results of the water quality detector 6 and the water flow sensor 11.
In the present embodiment, the solar panel 10 converts solar energy into electric energy, and the electric energy is converted by the inverter 9 to charge the battery 8. The storage battery 8 is connected with and supplies power to the controller 7, the water quality detector 6, the river control valve 4 and the sewage control valve 5. The controller 7 is connected with the water quality detector 6, the river control valve 4 and the sewage control valve 5, the water quality detector 6 transmits a water quality signal to the controller 7, the controller 7 sends a control signal to the river control valve 4 and the sewage control valve 5 according to the condition of water quality, and the river control valve 4 and the sewage control valve 5 act according to the control signal of the controller 7.
