太阳能自来水供水系统设计与试验

Design and Experiment of Solar Energy Running Water System

农村自来水系统普遍采用水塔式供水,需要人为监控水位,常出现溢水、缺水现象,供水水泵耗能较大,从而造成人力、电力和水资源的浪费,设计一种太阳能自来水供水系统。水塔内安装液位传感器,实时监测水位变化,并通过单片机控制系统,实现水泵自动抽水、停水处理。同时应用太阳能追日系统、MPPT控制器和降压斩波器为自来水供水系统中的水泵、控制电路提供电能。试验表明,太阳能自来水供水系统实现了水塔水位的实时监控,实现了太阳能电池驱动水泵的自动运行,有效解决了溢水缺水问题,达到了节水节能的高效用水目的。

The rural running water system commonly uses tower-style water supply,which demands men to monitor the water level,often turning out phenomena such as overflowing and lacking. Because of relatively high power of pump,it causes waste of human resource,electricity and water resource. A new type of solar energy running water supply system was designed. The water tower was installed liquid level sensor monitoring change of water level momently,via the single chip microcomputer,achieving goal of automated process on pumping and stopping pumping. At the same time,it used a solar energy tracking system,MPPT charging controller and buck chopper to supply electricity for the pump and control circuit. Experiments showed that this type of running water supply system achieved goal of monitoring water level momently and automatic operation of solar energy driving pump,also solved with problems of overflowing and lacking,attained goal of using water efficiently by saving water and energy.
