摘要
分析了渠系自动化的发展现状,介绍了水力自动溢流堰及其恒定水位的工作原理,并根据该装置良好的恒定水位性能,研究其在渠系自动化流量调控的应用条件和实现方法,其中对在取水口处应用和渠道中的联合运用两种方法作了进一步探讨。在渠道自动化上游控制中,能有条件地取代常用的水力自动闸门,可以实现真正恒定水位的目的,使得渠系自动调控方法简便,精度高。
The development situation of canal system automatic control is analyzed. The principles of the hydraulic overflow weir and its stable water level are introduced. The application conditions and implementation method for automatic control of discharge in the canal system are researched according to the perfect water level stability properties of the device, and its applications at the intake and conjunctive use in the canal system are further explored. In the automatic control at the upstream of the canal system, it can replace the conventional hydraulic sluice to realize the goal of stable water level, and can make the automatic control of the canal system very easily with high precision.
