虹吸式波涌流灌溉水力自控装置设计

Design of hydraulic automatic control devices for siphon surge irrigation

针对目前波涌流灌溉存在的问题,设计一种能利用渠道内的水流动力,实现波涌流自动灌溉的节水灌溉装置,是推动波涌流节水灌溉技术发展的重要措施。研制的渠道虹吸式波涌流水力自动控制灌溉装置可在渠道输水的条件下,利用水车提升水流作为动力,通过稳压池、控制池(起计时器作用)等部件控制虹吸管定时形成虹吸或断开虹吸,完成波涌流节水灌溉的周期供水和周期停水,实现波涌流自动化灌溉。

Regarding the problems with siphon surge irrigation at present, a water-saving device that can help to realize automatic irrigation is designed by taking the advantage of flow dynamics within the canal. It shall play a critical role in the development of water-saving irrigation technology. It helps to realize automatic surge irrigation by employing water wheel as power to lift water, and control siphon with voltage regulator pool and control pool （ used as time-meter） under the condition of water conveyance in the canal, so as to complete the cycle of water supply and cut off.
