Land management surveying instrument convenient for outdoor use and surveying method

Abstract

The invention discloses a land management surveying instrument convenient for outdoor use. The instrument comprises a telescope, a tripod and a balance adjusting device. During surveying and mapping,the tripod is opened; the telescope is installed on a telescope platform in parallel, a balance weight is installed below the telescope platform, and after the position of the telescope platform is fixed, the balance weight is detached; a third rotator is kept closed, and a first rotator and a second rotator are opened; and after the tripod is adjusted, the second rotator and the third rotator areclosed, and the telescope can be used for surveying and mapping when the telescope is fixed. According to the invention, the telescope platform can be automatically leveled by using gravity, and manual leveling by using human eyes and hands is not needed any more; through the cooperation of a first crank arm and a second crank arm, the leveled telescope is not influenced when the height or inclination angle of the tripod is adjusted, so that repeated telescope leveling actions are not needed any more, the use procedure is simplified, and the operation difficulty is reduced.

Description

technical field [0001] The invention relates to the field of land management surveying and mapping, in particular to a land management surveying and mapping instrument and a surveying and mapping method that are convenient for outdoor use. Background technique [0002] In the fields of state-owned land census, housing and land integration, geographic national conditions detection, balance of occupation and compensation, returning forests to farming, earthwork surveying, and geographic information data collection, etc., it will be widely used in surveying and mapping instruments. An instrument for height difference between points, which measures the height difference between ground points according to the principle of leveling. During use, after adjusting the level of the surveying instrument, if you need to adjust the height of the telescope when using the surveying instrument, you can only adjust the height of the telescope by adjusting the tilt angle of the tripod, and the...

[0002] In the fields of state-owned land census, housing and land integration, geographic national conditions detection, balance of occupation and compensation, returning forests to farming, earthwork surveying, and geographic information data collection, etc., it will be widely used in surveying and mapping instruments. An instrument for height difference between points, which measures the height difference between ground points according to the principle of leveling. During use, after adjusting the level of the surveying instrument, if you need to adjust the height of the telescope when using the surveying instrument, you can only adjust the height of the telescope by adjusting the tilt angle of the tripod, and then readjust the height of the telescope. very troublesome
