Abstract

The invention discloses a hydrometric station cableway type flow velocity automatic measurement device. The hydrometric station cableway type flow velocity automatic measurement device comprises a plurality of fixing cables, wherein top ends of the fixing cables are hung on a cableway system, and an instrument container with an acoustic doppler current profiler (ADCP) controller arranged inside is connected with lower ends of the fixing cables. A flow guiding structure is fixed below the instrument container through a connecting rod, and an ADCP which is electrically connected with the ADCP controller is fixed at the bottom end of the flow guiding structure. The ADCP controller communicates with a control system installed in a control chamber of a hydrometric station, and a motor of the cableway system is controlled by the control system. The hydrometric station cableway type flow velocity automatic measurement device is high in reliability, the problem that an existing device needs to be operated by a test worker on the spot is solved, and the aim of being guarded by nobody is achieved.

Description

technical field [0001] The invention relates to an automatic flow measurement and monitoring system for an unattended hydrological station in cableway mode, in particular to a cableway type automatic flow velocity measurement device for a hydrological station. Background technique [0002] At present, hydropower projects have been built before and after the river section tested by many basic hydrological stations, which has seriously damaged the water level-flow relationship of the river section originally tested by the hydrological station, and the cross-sectional lateral flow velocity distribution has also become more complicated due to the operation of the power station. [0003] In order to solve the problem of water resources monitoring in such hydrological stations, the current common practice is still to increase the number of hydrological surveys as much as possible, or directly transfer the outflow process of upstream (downstream) hydropower projects, resulting in an...
