Automatic positioning laser geological compass

Abstract

The invention discloses an automatic positioning laser geological compass, relating to the field of a compass device and solving the problem that the magnetic needle and a seabed line of the current geological compass are needed to be reregulated in measurement of each target object to cause time waste, and the like. A plastic bearing is arranged between a groove of an outer disc of the automatic positioning laser geological compass and a cylindrical outer box of a Tianchi, the inner ring of the plastic bearing and the cylindrical outer box of the Tianchi are adhered and fixed, and an inner disc and the upper end of the inner ring of the plastic bearing are adhered and fixed; a circular hole I is formed in the middle of the outer disc; and a circular hole II is formed in the middle of a base, and a mounting groove for fixing a laser emission assembly is formed in an upper cover. The automatic positioning laser geological compass has a simple structure, and is convenient to use, and time-saving.

Description

technical field [0001] The invention relates to a compass device, in particular to an automatic positioning laser geological compass. Background technique [0002] Compass, also known as compass, is widely used in military, navigation, forestry, exploration, construction and other fields. The compass consists of three parts: the Tianchi, the inner disk and the outer disk. The Tianchi is composed of a thimble, a magnetic needle, a submarine line, a cylindrical outer box and a glass cover; the inner disk is the azimuth disk, and the azimuth disk is fixed with the cylindrical outer box on the Tianchi. The contents are engraved on different rings of the azimuth dial; the outer disk is usually circular, and the crystal lines passing through the periphery of the outer disk and forming a cross in the center hole of the outer disk form the Tianxin Ten Dao, or positioning lines, which are used to read the contents on the inner disk. The shell of the geological compass is generally c...

Problems solved by technology

When measuring the next target, it is still necessary to repeat the same steps above. First align the target and then adjust the magnetic needle and the seabed line to read the data, instead of directly reading the data after aligning the target. This method is suitable for different targets. The measurement steps that need to readjust the coincidence of the magnetic needle and the bottom line not only bring a certain degree of difficulty to beginners, but also cause a waste of time for frequent users

At the same time, when the light is low and the visibility is low, there is a problem that the target cannot be seen clearly when using the compass. Usually, it is inconvenient, laborious and time-consuming to wait for the obstacles blocking the line of sight to disappear automatically or to use other light sources.
