Slope comprehensive measurement instrument

Abstract

The invention discloses a slope length, slope gradient and slope direction comprehensive measurement device. The slope length, slope gradient and slope direction comprehensive measurement device mainly comprises a laser range finder, a range finder fixer, a slope direction measuring compass, a round leveling instrument and a support rod, wherein the laser range finder is fixed on the support rod through the range finder fixer; the support rod is also fixedly provided with the slope direction measuring compass and the round leveling instrument. The slope length, slope gradient and slope direction comprehensive measurement device obtains the slope length and the slope gradient by utilizing similar triangles and the principle of resolving a right triangle and obtains the slope direction by utilizing a terrestrial magnetism principle; and the slope comprehensive measurement instrument has the advantages of being convenient, fast, efficient and integrated in operation, and the like.

Description

technical field [0001] The invention belongs to the field of topographic measuring instruments, in particular to a comprehensive measuring instrument for slope length, slope and slope aspect. Background technique [0002] The measurement of slope length, slope, and slope aspect is a necessary means to obtain slope characteristic data, and is an important data source for geological survey, engineering construction, agricultural production, soil erosion investigation, and soil erosion prevention and control. However, the traditional slope length measurement method is to measure the slope length with a tape measure or a bamboo pole, which not only requires the cooperation of multiple people, but also has a slow measurement speed, which is difficult to meet the needs of large-scale topographic measurements; using traditional total stations and theodolites Such precision instruments measure the slope. Although the accuracy is high, the instrument is bulky, the operation is cumber...

Problems solved by technology

However, the traditional slope length measurement method is to measure the slope length with a tape measure or a bamboo pole, which not only requires the cooperation of multiple people, but also has a slow measurement speed, which is difficult to meet the needs of large-scale topographic measurements; using traditional total stations and theodolites Such precision instruments measure the slope. Although the accuracy is high, the instrument is bulky, the operation is cumbersome, and the measurement efficiency is low. Although the compass, level and other slope measurement tools are more convenient to carry, the measurement error is relatively large, and it is also easily affected by the magnetic field and humidity. other external environmental influences

Moreover, for the acquisition of the three characteristic data of the slope length, slope, and slope aspect of a slope, the traditional method is to use a variety of different devices to obtain them separately, which is not only inefficient, but also has uneven measurement accuracy.
