A Pointing Method of Geological Compass Based on Sun Projection

Abstract

The invention relates to a sun projection-based geological compass and a pointing method. The sun projection-based geological compass comprises a magnetic needle, a horizontal dial, a horizontal dial correction button, a time disk, a time disk correction button and a telescopic projection needle, wherein the time disk correction button is connected with the time disk; the work of correcting and adjusting the time disk is performed by rotating the button; the horizontal dial correction button is connected with the horizontal dial; the time disk and the horizontal dial are next to each other but are separated from each other; scales of the time disk and the horizontal dial correspond to each other; the telescopic projection needle is placed at the central position of the compass. According to the sun projection-based geological compass and the pointing method, a traditional geological compass is transformed according to an optical projection technology, and the direction can be judged correctly and the attitude of a geological body can be measured accurately in a magnetic field chaos area.

Description

technical field [0001] The invention relates to the field of pointing equipment, in particular to a geological compass and pointing method based on sun projection. Background technique [0002] In the prior art, the working principle of the geological compass is based on the geomagnetic field, but in many magnetite areas or areas containing magnetic minerals (the most common magnetic minerals in various rocks in nature have iron titanium, iron manganese oxide and hydroxide minerals, iron sulfides and iron, cobalt, nickel, alloys, etc.), due to the great impact of mineral magnetism on the geomagnetic field, the current geological compass cannot be used, and strong magnetic areas (such as magnetite areas, magnetic rocks, etc.) Body area) is an important field of geological research work, which has caused great inconvenience to the work of field workers such as geologists. [0003] In view of the above-mentioned defects, the author of the present invention has finally obtained...
