淤泥质河床铅鱼缆道测流信号的设计方法

Design Method of Flow Measurement Cignal of Suspended Cableway with Streamlined Weight in Silt River Bed

文中叙述了义棠水文站淤泥质河床上缆道测流信号的形成、传输、处理系统的设计、试验研究的基本情况及工作原理等。"失重"开关与河底开关组成的双重保险装置是解决我国北方地区淤泥质河床水面、河底、流速信号的产生与传输的自动化缆道的关键问题,文中对之做了具体叙述,旨在为类似的水文缆道工程设计提供参考。

This paper explains the basic situation and work priciple of the design and test research on formation, transfer and dealing of flow measurement cignal of suspended cableway with streamlined weight in silt river bed of Yitang Hydrologic Station. The dual assurance installation consisting of weightless switch and river bottom switch is the key element to solve the correct generation and transfer of water bed, water surface and velocity cignal in river with silt bed of our country＇s north zone. All of these are concretely narrated so as to provide reference for the design of other similar cableway.
