A method of changing the water volume by adjusting the position of the center of gravity of the tipping bucket

Abstract

The invention relates to a method for changing the water yield by adjusting the skip-bucket gravity center position. An adjusting screw rod is movably arranged in a skip bucket of a skip-bucket rain sensor, and a combination body is formed through the skip bucket and the adjusting screw rod; by changing the position of the adjusting screw rod, the gravity center position of the combination body ischanged. The method has the advantages that the adjusting screw rod with the certain mass is additionally arranged on the skip bucket, the position of the adjusting screw rod is changed, the gravitycenter of the skip bucket is thus changed, changing of the water yield is achieved, the structure is simple, operation is convenient, the cost is low, and the method can be widely suitable for the skip-bucket rain sensor.

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 the 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 is equ...

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. It needs to be adjusted through multiple tests. The position of the stopper is adjusted by adjusting the adjustment screw, so that the angles on both sides cannot be guaranteed to be equal, and there will be problems with the size of the bucket.
