Method for changing water volume by adjusting gravity center of upper tipping bucket

Abstract

The invention relates to a method for changing water volume by adjusting the gravity center of an upper tipping bucket. The upper tipping bucket is arranged above a tipping bucket of a tipping-bucket-type rain sensor; rotating shafts of the upper tipping bucket and the tipping bucket are parallel to each other, and are on the same vertical surface; an adjusting screw rod is arranged on the upper tipping bucket movably; the position of the adjusting screw rod in the upper tipping bucket is changed to change the gravity center position of a combined body formed by the upper tipping bucket and the adjusting screw rod. The method has the advantages that the gravity center of the combined body formed by the upper tipping bucket and the adjusting screw rod is changed through change of the position of the adjusting screw rod in the upper tipping bucket, the weight of water flowing into the tipping bucket from the upper tipping bucket is further changed, and accordingly, measurement accuracy is adjusted.

Description

technical field [0001] The invention relates to the field of tipping bucket rainfall measurement, in particular to a method for changing the water volume by adjusting the center of gravity of an upper tipping bucket. Background technique [0002] The traditional tipping bucket rain sensor changes the quality of each bucket of water by adjusting the position of the stopper. Such as figure 1 Shown is the existing tipping bucket rain sensor, wherein 1 is the frame, 2 is the adjustment screw; 3 is the collection tipping bucket, 4 is the metering tipping bucket; 5 is the counting tipping bucket; 6 is the tipping bucket; 7 is the stopper; 8 is the magnetic steel. By adjusting the adjustment screws on both sides of the tipping bucket, and then adjusting the position of the stopper, thereby adjusting the rotation angle of the tipping bucket, to change the quality of each bucket of water, the magnetic steel is installed in the middle of the counting bucket, and the magnetic steel i...

Problems solved by technology

Obviously, the water in the tipping bucket can control the water quality of each tipping bucket according to the appropriate weight of the tipping bucket and the tilting angle controlled by the overturning block. However, the traditional tipping bucket cannot make the quality of the rain proportional to the angle. The adjustment can only be corrected by the experience of the tester, and it needs to be adjusted through multiple tests, and the position of the stopper is adjusted by adjusting the adjustment stud, so that the angles on both sides cannot be guaranteed to be equal, and there will be problems with the size of the bucket
