一种高流速小河流人工流量测验装置与应用

在河宽较小的河流或渠道流量测验中,若遇流速较大时,采用人工桥测、走航式ADCP等方式施测流量极为不便。为解决小河流高流速情况下的人工流量测验问题,研制了一套由轨道基座、行车、刹车组、悬杆升降部件、计数器和悬杆固定架等组成的人工流量测验装置。该装置采用悬杆搭载流速仪,通过机械装置实现悬杆(测深杆)的水平移动和垂直移动,将流速仪精准传送到测流断面任意位置,实现小河道高流速监测。经牛栏江-滇池补水工程输水线路末端站两年多的实际应用,在高流速3~5m/s时,运行稳定可靠,使用方便。

Application of A High Flow Velocity Measuring Device for Small Rivers

In the flow hydrometry for small rivers or channels, if flow velocity is high, it is inconvenient to use manual bridge measurement or scoopfish ADCP. In order to solve this problem, we developed a flow measuring device composed of orbital base lifting, driving, brake set, hanging rod part, counter and suspension rod holder. The device using suspension rods equipped with flow meter, can horizontally and vertically move, so as to accurately reach the section to be monitored. This device has been used to the end of the Niulanjiang-Dianchi Water-Delivery Project for 2 years. The result shwo that the device operation is stable and reliable when the high flow velocity is 3-5m/s
