A multifunctional geological compass

Abstract

The invention discloses a multi-functional geological compass, which comprises a shell, a base, and a connecting shaft connecting the shell and the base, a roll angle plate is arranged on the outer side of the connecting shaft at the lower part of the shell, and a reflector is inlaid on the inner surface of the shell. A stop tray and a magnetic needle are movably connected inside the upper end surface of the base, and an annular horizontal dial is arranged on the upper end surface of the base outside the stop tray and the magnetic needle. Locking mechanisms are provided on the arms. The multi-functional geological compass of the present invention is simple and practical, and has a compact structure. The contact mode of the housing is expanded by the rotating arm of the housing, and the measurement accuracy is improved; the inclination measurement and the inclination and direction measurement can be carried out simultaneously, the process is simple, the use is convenient, and the data is accurate. It has low requirements for operators and good use effect.

Description

technical field [0001] The invention relates to the technical field of geological surveying, in particular to a multifunctional geological compass. Background technique [0002] Geological compass, also known as "pocket theodolite", is a tool for identifying directions, determining positions, measuring geological occurrences and rough topographic maps in field geological work. It mainly includes magnetic needles, levels and inclinometers. It can be divided into chassis, The shell, the upper cover, and the main instruments are all fixed on the chassis, and the three are connected into a whole with hinges. The geological compass has the advantages of convenient use and wide range of uses. When the existing geological compass measures the occurrence of rock formations, the geological compass must be held flat by hand. The upper cover must be kept parallel to the back-measured rock formations. It is difficult to keep the upper cover parallel to the rock strata in the outcrop, w...

AI Technical Summary

Problems solved by technology

The geological compass has the advantages of easy use and wide application. When the existing geological compass measures the occurrence of rock formations, the geological compass must be held up by hand. The upper cover must be kept parallel to the back-measured rock formations. It is difficult to keep the upper cover parallel to the rock strata in the outcrop, which makes the measured data inaccurate. In addition, because the dip angle measurement and the dip and strike measurement cannot be carried out at the same time, it is necessary to mark the dip after dip or strike measurement Measurement, the measurement process is cumbersome, and the final inclination measurement data may be inaccurate after repeated operations, which requires high requirements for operators and poor use effect
