[0031] The following is a detailed description of the working principle of this rainwater automatic collection, natural purification and autonomous recycling system:

[0032] In this embodiment, the rainwater automatic collection, natural purification and autonomous recycling system integrates a rainwater drainage network 1, a gate valve 2, a water diversion pipe 4, a water collection pool 5, a water collection pump group 6, a liquid level meter 7, a control unit 8, a water collection pipeline 9, an artificial water system 10, an overflow pipeline 11, a first municipal rainwater drainage main line 3, a second municipal rainwater drainage pipeline and a circulating water pump 13.

[0033] In actual application, the control unit 8 is designed with a metering device, a manual-automatic conversion switch, a manual start-stop control, etc. The rainwater drainage network 1 is separated from the first municipal rainwater drainage main line 3 by the gate valve 2, and the rainwater drainage network is connected to the collecting tank 5 through the water diversion pipe 3.
