Description

Auxiliary devices for leveling rods

technical field

The utility model relates to the technical field of power equipment, in particular to an auxiliary device for a level gauge.

Background technique

At present, the methods of measuring elevation are mainly leveling method, triangulation elevation measurement method and GPS analog elevation measurement method. The principle of the leveling method is to measure the height difference between two points on the ground, and then calculate the height of the unknown point based on the height difference of the known point and the measured height difference between the two points.

When checking the bottom elevation of the power well, the leveling method is generally used for measurement. When the power well is relatively shallow and there is no water accumulation in the power well, the level gauge and leveling rod can be directly used for measurement. When the power well was relatively deep, the length of the leveling rod could not meet the requirements of the well depth of the power well. When there is accumulated water in the power well, because the leveling rod is made of wooden material, it cannot be stretched into the bottom of the well for measurement. In the prior art, the depth of the bottom of the power well is often measured by measuring the elevation of the top of the well cover and the distance from the top of the well cover to the bottom of the well. When measuring, the top elevation of the well cover is measured with a level gauge and a leveling rod, and the distance from the top of the well cover to the bottom of the well is measured with a measuring rope. Since the measuring line may deviate during the measurement process, the distance between the top of the manhole cover and the bottom of the well measured by using the measuring line is not very accurate. The measuring rope also has a certain degree of elasticity, and the accuracy of the above measuring method is relatively low.
