【 摘 要 】

Aiming at improving the environment and the problem that how to effectively use rainwater collected in the construction of a sponge city, a scheme was proposed to generate electricity by rainwater potential energy on the roof and solar power during dry weathers. When it's raining, the amount of rainwater controlled by the intelligent level control system and discharge device enters the system through a designed collector. After passing the packet filter and pressure pipeline, the rainwater potential energy is converted into electrical energy through a hydroelectric generator and finally stored in a water reservoir. The electrical energy is stored in a battery. When there's no rain, solar energy is stored by a solar panel and a high-efficiency light tracking system to provide water working system or a small resident electrical system with electrical energy in the sponge city. Compared with thermal power generation, they do not cause environmental pollution. As a consequence, the two mechanisms complement each other in time and space to achieve the goals of environmental protection, energy conservation and emission reduction.
