Description

Technical Field

[0001] The utility model relates to the technical field of flow velocity measuring equipment, in particular to a small floating type hydraulic flow velocity measuring equipment. Background Art

[0002] To measure flow with a velocity meter, you need to choose a straight river section, set a section perpendicular to the flow direction, and set a starting point stake. The conventional practice is to measure the starting distance and water depth of each vertical line on several sounding vertical lines along the section, obtain the section data, and use the velocity meter to measure the flow velocity on some or all of the sounding vertical lines. On each vertical line, the two-point method of measuring the velocity at 2 / 10 or 8 / 10 relative water depth, or the one-point method of measuring the velocity at 6 / 10 relative water depth is often used. In precision testing, the five-point method or eleven-point method with more measuring points can be used to divide the section into several parts according to the vertical lines, and calculate the partial flow by multiplying the average flow velocity of the part by the area of ​​the part. The sum is the total flow through the section. The average flow velocity of the section can be obtained by dividing the flow by the cross-sectional area. When there is frozen ice, ice holes should be drilled at each vertical line of the section, the "effective water depth" of the bottom of the ice layer and the bottom of the riverbed should be measured, the water-passing area should be calculated, and the flow velocity should be measured under the ice layer with a velocity meter to calculate the flow.

[0003] The flow velocity measuring instrument in the prior art cannot keep floating during use. Therefore, when the water level changes, the flow velocity measuring instrument will be submerged by the water level or cannot contact the water flow, thereby affecting the accuracy of the measurement. Therefore, it needs to be improved. Utility Model Content
