[0028] Working principle of the present invention: on rainy days, part of the rainwater naturally penetrates the permeable pavement layer 23 and the gravel layer 22 into the inside of the diversion trough 33 and flows into the main trough 31 through the water guide pipe 32, while the other part of the rainwater is collected by the open curbstone 25 to the sunken green space structure 24 and penetrates into the inside of the main trough 31. In the process of rainwater infiltration, most of the impurities in the rainwater can be purified by the gravel layer 22, and the collected rainwater enters the primary purification tank 41 through the confluence pipe 35. The rainwater is first cleaned by the impurity removal part 43 in the primary purification tank 41. In addition to the large particles of impurities, the rainwater is pumped to the secondary purification pool 42 through the pumping equipment, and is successively passed through the quartz sand filling layer 47 and the activated carbon filling layer 45 to absorb the small particles of impurities contained, and then is disinfected by the ultraviolet disinfection structure 48 before entering the water storage device for storage. After the rainwater is purified, it can be used for urban irrigation, landscape water use, and environmental dust reduction. Therefore, the use of urban rainwater resources can effectively improve the urban ecological environment. At the same time, when the rainwater flows downward from the confluence pipe 35, the water of the confluence pipe 35 can be used. The potential difference can drive the water level drop power generation component 7 to generate electricity and realize energy utilization, and the photovoltaic panel 65 converts solar energy into electrical energy and stores it. Therefore, the collected rainwater is allocated through the electricity generated by new energy, and participates in the regulation of urban ecology by rainwater utilization. At the same time, the application of green energy facilities reduces the pollution of traditional energy production to the environment and improves the quality of urban ecological environment. The output shaft 68 is driven to rotate by the driving motor 69, and the rotating sleeve 62 and the support plate 63 are driven to rotate synchronously, so that the axial position of the photovoltaic panel 65 can be adjusted, and the screw 663 is driven to rotate by the reduction motor 662, and the movable rod 664 is moved on the surface of the screw 663 by the threaded cooperation between the screw 663 and the movable rod 664, so that the movable rod 664 moves out of the fixed tube 661. Therefore, the light receiving angle of the photovoltaic panel 65 can be adjusted, and the photovoltaic panel 65 can gradually follow the light deviation according to the light angle to ensure the power generation efficiency of the photovoltaic panel 65. Therefore, the use of the photovoltaic power generation component 6 and the water level drop power generation component 7 can bring into play the comprehensive benefits of sponge city ecology and new energy facilities.
