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 a cableway mode unattended hydrological station automatic flow measurement monitoring system, in particular to a hydrological station cableway type flow velocity automatic measurement device. Background technique [0002] At present, many basic hydrological stations have built hydropower projects before and after the test sections of the hydrological stations, causing serious damage to the water level-flow relationship of the original test sections of the hydrological stations, and the cross-sectional velocity distribution is also more complicated due to the operation of the power station. [0003] In order to solve the problem of water resources monitoring of this type of hydrological station, the current common practice is still to increase the number of hydrological tests as much as possible, or to directly transfer the outflow process of upstream (downstream) hydropower projects, resulting in an imbalance of the upstream and downst...
