Description

Adjustable Angle Level Ceremony Height Measuring Instrument

technical field

The utility model relates to a height measuring instrument, more precisely, a leveling ceremony height measuring instrument capable of finely adjusting angles.

Background technique

Height surveying is the work of surveying to determine the elevation of ground points. The elevation of a point generally refers to the distance from the point to the geoid along the plumb line, also known as altitude or absolute elevation. Leveling is the most precise method of measuring the height difference between two points on the ground by using a horizontal line of sight and by means of a ruler erected on the ground, and then calculating the height of another point based on the height of one point. The method is mainly used in the establishment of the national leveling network. In addition to leveling at the national level, there is also general leveling. It uses instruments with low precision, and the calculation procedures are relatively simple. It is widely used for encryption in national leveling networks, or to independently establish elevation control networks for surveying and general engineering construction, as well as for line leveling and surface leveling. Measure work. The supporting legs of existing height measuring devices can only rotate along one plane, which cannot be well adapted to different types of terrain. Existing height measuring devices often need to fine-tune the angle of the level after the level is installed. The existing method needs to move the supporting legs, which is very laborious and easy to over-adjust.
