Description
Technical Field
The utility model discloses a flow direction declination measuring device under water belongs to hydrology observation equipment technical field.
Background
The flow rate is the basic data reflecting the changes of hydraulic resources and the water quantities in rivers, lakes and reservoirs. The deflection angle of the flow direction has great influence on the measurement result of the flow speed, so that the error of the measurement result of the flow speed is large. When the deflection angle is 10 degrees, the error is 1.5 percent; when the deflection angle is 25 degrees, the error can reach 10 percent. When the flow direction instrument is used for measuring the flow direction near the low water surface, a dial at the upper end of a rotating shaft of the flow direction instrument is perpendicular to the rotating shaft, and when the compass reading is a, (a is an included angle formed when a north-pointing direction line at a certain point is overlapped with a flow measuring section line), the digital display angle gauge reading is quickly read. When the direct-reading instantaneous flow direction instrument is used and the reading is unstable, the reading is continuously carried out for 3-5 times, and the average value is taken. The dimensions of the spoiler tail are such that it is free to rotate with the flow direction at low flow velocities. The existing flow direction device comprises a protractor, a collimator, a rotating shaft and a tail wing. The protractor is used for measuring a flow direction deflection angle; the direction of the collimator is controlled to be superposed on the flow measuring section line; the tail fin is used for meeting the flow direction. The disadvantages are as follows: the control direction of the collimator has larger deviation, which causes larger error of deflection angle degree, and the tail wing continuously swings in flowing water, which causes the pointer of the protractor to continuously swing, so that the protractor has lower instantaneous reading precision and is difficult to observe accurate data. Therefore, the research on the high-precision underwater flow direction deflection angle measurement is significant to the accurate measurement of the flow.
