Description

Technical Field

[0001] The utility model relates to the field of engineering technology, and particularly relates to an engineering precision measuring gradient ruler. Background Art

[0002] A gradient ruler is a graphical curve ruler used to determine the corresponding ground gradient according to the horizontal distance of contour lines on a topographic map or its reverse process. In engineering, a gradient ruler is commonly used to detect buildings.

[0003] During the detection process, a common gradient ruler relies on the position of the bubble in the internal water pipe to determine the current inclination angle. However, limited by other environmental factors such as thermal expansion and contraction, the size of the bubble in the water pipe will change slightly. It is difficult to accurately determine whether the bubble is in the central position only relying on the scale line on the surface of the fixed-position water pipe, resulting in a decrease in the accuracy of gradient detection.
