摘　　要：为了节约水资源,及时灌溉并避免中午灌溉植物,设计一种以自来水发电来供电的自动灌溉装置。该系统发电部分由外壳串接在进水管和出水管之间,小型防水发电机内置于密封外壳中,让水流带动风叶发电,产生约4～5V电压,再通过升压电路将它升至12V,储存到蓄电池里备用。自动灌溉部分通过湿敏电阻和光敏电阻采集信号,由NE555判断,再经过与门CD4073,最后将信号传输给延时电路进行延时控制电磁阀。电路中湿度、亮度及延时时间均可调节。实验证明,该种自来水发电装置不仅密封性能好,功率高,而且可以节约能源,美化环境,符合当前节能型社会的政府导向。An automatic irrigation system with tap-water generating electricity was design for saving water,irrigating plants in season and avoid irrigating it at noon.The electricity generating equipment is connected between two water pipes,the small waterproof electricity generator is placed in a sealed plastic shell,the power is generated when the water flowed through turbine blades and stored into a storage battery after the voltage is boosted from 4～5Vto 12 Vthrough the voltage boost circuit.The signals are gathered by the humidity resistance and the photosensitive resistance,judged by NE555,through CD4073 and the delay circuit to control the magnetic valve,the humidity,brightness and delay time can be adjusted. The tap-water generating electricity system owns perfect sealing property and high efficiency through experiments.The device can save energy and beautify the environment.
