The invention discloses a channel water flow online measuring device comprising a rectangular frame and characterized in that the channel water flow online measuring device comprises the rectangular frame, the upper side of the rectangular frame is fixedly connected with the lower side of a sliding groove plate, and the sliding groove plate is provided with first sliding grooves, second sliding grooves, third sliding grooves, fourth sliding grooves and fifth sliding grooves which are symmetrical; and the two first sliding grooves, the two second sliding grooves, the two third sliding grooves, the two fourth sliding grooves and the two fifth sliding grooves are symmetrical about the transverse center line of the sliding groove plate, and sliding columns are arranged in the two first sliding grooves, the two second sliding grooves, the two third sliding grooves, the two fourth sliding grooves and the two fifth sliding grooves correspondingly. The invention relates to the field of water flow measuring equipment, and in particular, relates to the channel water flow online measuring device. According to the device, through simultaneous measurement of multiple measuring rods, real-time online measurement of multiple vertical lines and multiple sections of a river channel is achieved, measurement data are more comprehensive, the flow measurement precision is higher, and the data are more accurate.
Description
technical field [0001] The invention relates to the field of water flow measurement equipment, in particular to an online measurement device for channel water flow. Background technique [0002] At present, the water flow measurement of open channels mostly adopts the flow velocity area method, the standard section method, the canal system building method and the weir and flume method. There are problems such as low measurement accuracy. In order to realize the accurate measurement of open channel flow, the flow velocity area method is mostly used. Common flow velocity measurement methods include acoustic Doppler, radar, rotor, etc. The acoustic Doppler has the problem that it is greatly affected by water quality. It is not suitable for occasions with a lot of water and water quality debris. In addition, most of the online flow measurement is fixed on the bank slope of the channel, which can only realize the flow measurement of a single measurement line, and cannot reflect ...
