望亭枢纽浮漂安装ADCP在线流量比测分析

Online flow comparative analysis of ADCP for floating installation in Wangting Hub

河道ADCP垂线法在线流量测验性能稳定,流量数据精度高,得到广泛使用。采用座底安装ADCP方式,水下安装强调安装稳固,严格朝向河道主流方向,深水时需要专业的潜水人员,施工成本高。改进为浮漂体安装,ADCP流速传感器、无线传输设备及电源都安置在航标灯式浮漂体上,安装、维修时拆装可快速完成,适应地处复杂的感潮、河口、航运、船闸、分水及大型抽水站的在线测流。望亭枢纽的排洪期及引水期在线测量比测成功表明,双垂线法浮漂ADCP在线测流系统简单实用。

Online flow measurement by ADCP vertical line method is widely used for its stable performance and high accuracy of flow data.At first,ADCP is installed at the bottom of the seat,and the underwater installation emphasized stable installation,strictly facing the mainstream of the river,and the construction cost is high when professional divers are needed in deep water.The installation of floating body is improved.ADCP velocity sensor,wireless transmission equipment and power supply are all placed on the beacon light floating body,and disassembly and assembly can be done quickly during installation and maintenance.It is suitable for the online flow measurement in complex tidal,estuary,shipping,ship lock,water diversion and large pumping stations.The success of online measurement and comparison in flood discharge period and diversion period of Wangting Hub shows that the online flow measurement system of floating ADCP with double vertical lines is simple and useful.
