Problems solved by technology

[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

Embodiment Construction

[0025] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0026] see figure 1 As shown, it is a structural schematic diagram of the compass of the present invention; the compass includes a magnetic needle 1, a horizontal dial 6, a horizontal dial correction button 2, a time disk 5, a time disk correction button 2 and a retractable projection needle 4, wherein,

[0027] The time dial correction button 2 is connected with the time dial 5, and it performs the correction and adjustment work of the time dial by turning a knob.

[0028] The horizontal scale correction button 2 is connected with the horizontal scale 6 .

[0029] The time dial 5 and the horizontal dial 6 are close together, but separated from each other; the scales of the two are corresponding; the scale of the time dial 5 adopts such a representation mode: the dial is divided into 360 parts, starting f...

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...
