Technical Field

The invention relates to a rainwater pipeline power generation device, a building public power system and a building public power method, and belongs to the technical field of hydrodynamic power generation.

Background

Energy is a material basis on which human beings rely to live, but nowadays, the energy consumption is increasingly increased, and the environmental problem is also increasingly aggravated by the use of fossil energy. World countries are increasingly paying attention to the application of various energies in response to environmental problems such as global warming. In addition, the land industry is rapidly developed, high buildings stand, the rainwater potential energy on the high buildings is a natural pollution-free green energy, and various natural clean energy sources such as the high-level fall energy of rainwater and the like are developed and utilized to play an important role in relieving the energy crisis and reducing the environmental pollution.

In addition, corridor lamps are often arranged between corridors of a high-rise building, so that illumination can be provided at night or when light is insufficient, and the safety of residents is ensured; the exhaust fan is arranged to provide clean air for the corridor, and the safety of air quality is guaranteed. But sometimes the instability of the circuit will also cause the lamp or the exhaust fan to be shut down. The storage battery is charged by utilizing the high-level fall energy of the rainwater, so that the storage battery can be used as an auxiliary power supply for the electric lamp and the exhaust fan, and the stable operation of the electric lamp and the exhaust fan can be ensured.

Furthermore, many residents will return to rooms such as bedrooms after the clothes are aired on the open balcony. Once it rains, the resident cannot detect the outside weather change at the first time, which causes the occurrence of the condition that the clothes are wet. It is very inconvenient for the resident.

Finally, the existing pipeline power generation device does not provide fan blades for effectively utilizing rainwater energy, the design of a sewage discharge pipeline is easy to block, and the existing pipeline power generation device does not have the function of reminding residents of coming rainy days.

In summary, the invention provides a rainwater pipeline power generation device and a building public power system and method.
