Abstract
The utility model relates to a hydrological cableway testing system of a simple-structured and highly-automatic suspended acoustical Doppler velocity meter, which includes a pair of brackets arrange on the two sides of a river, a main rope and a circulating rope arranged between the brackets, a trolley arranged on the main rope, a winch in transmission connection with the circulating rope for controlling the displacement of the trolley, and a lead fish connected with the trolley through a lead fish rope, wherein the lead fish rope is in transmission connection with the winch; the winch is connected with a control console for controlling the working state of the winch; and the acoustical Doppler velocity meter is suspended on the trolley. The system improves the automation degree of the flowrate measurement, shortens the testing period, reduces the labor intensity of the testing staff, and improves the working efficiency and the result quality. By adopting the system, the water supply measurement becomes more accurate, the method becomes more advanced, the credibility is high, and the accountability for managing the water resource of the Yellow River is enhanced.
Description
Technical field
The utility model relates to a kind of hydrometric cableway test system that suspends the acoustic Doppler current meter in midair; Hydrometric cableway is, the on the coast cableway system of operation overhead across the river, in order to carry and control instrument carries out hydrologic survey or silt, water quality sampling operation on this place's active cross-section.
Background technology
Draw the following problem of cableway test system ubiquity that yellow water lock discharge measurement uses at present: the one, the fish lead level, vertically to move control reliability poor, out-of-control phenomenon often occurs, and speed adjusting performance is unstable, and this method for controlling speed regulation is eliminated; The 2nd, start point distance, the depth of water, flow speed data lean on artificial counting or mechanical count, and poor reliability can not be by computer Recognition, let alone computer-automatic collection; The 3rd, the calculating of flow achievement is by manual calculation, and brainwork intensity is bigger.Therefore be necessary to develop that the test precision is high, automaticity is high, draw the special-purpose hydrometric cableway of yellow canal capacity test; Use the brand-new current meter of go-go technology, material and the means design cableway that crosses the river; Make it that hydrology data can accurately and timely be provided; Be the Yellow River tail water resource management and dispatch service, for offering high-quality service along industrial and agricultural production of yellow two sides and resident living water.
