first, according to the height of survey ship or bridge, utilize a plurality of spacing guide arms (901) and threaded rod (7) to assemble, constitute the bearing structure of extensible to riverbed bottom, after the combination is accomplished, the mounting bracket card is fixed at the edge of survey ship or bridge through fastening bolt with it.
And secondly, adjusting the distance between the connecting rod (13) and the shuttle-shaped seat body (1101) adjusting groove by the positioning bolt (1104), so that the main speed measuring turbine (12) and the auxiliary speed measuring turbine (2) are in a balanced state when the river is on the shore, namely the numerical value of the angle sensor (1105) is zero, and the preparation work before the river speed measuring sensor is measured is completed.
And thirdly, in the measurement stage, driving two conveying belts in the lifting mechanism (8) to move through a driving motor, further driving the lifting mechanism (8) to move up and down through friction force, vertically extending the speed measuring sensor into the bottom of the river, and standing for 10-30min until the vibration of the limiting mechanism (9) is weakened or in a static state is observed.
Fourthly, the stepping motor (6) drives the threaded rod (7) to rotate, the ball nut (1002) drives the sliding sleeve (1001) to move up and down, the depth of the measuring seat (11) below the river surface is adjusted, and then the measuring depth of the speed measuring sensor can be adjusted quickly.
And fifthly, obtaining two river flow velocity values through the main speed measuring turbine (12) and the auxiliary speed measuring turbine (2), recording data and calculating an average value when the errors of the two sets of data are within a set range, obtaining the river flow velocity at a corresponding depth, recording the angle of the angle sensor (1105), and verifying the flowing direction change and fluctuation of the river.
Sixthly, when the water flow direction changes in the measurement stage, the speed measuring sensor can be quickly kept in dynamic balance with the water flow direction through the guiding effect of the advection fin plate (401), the fluctuation phenomenon in the measurement process is reduced, the monitoring module (402) can record images such as sediment and water flow of the river bottom, and the dynamic change of the speed measuring sensor during adjustment at each time is monitored.
