Abstract

The invention relates to an instrument fixing device for water area magnetic survey. The device comprises a bottom plate, a box body and a probe rod, the bottom plate is fixed on a ship body, the box body is fixed on the bottom plate, one end of the probe rod is arranged and fixed in the box body, and the other end of the probe rod is used for being connected with a magnetometer probe. The influence of human factors is reduced, the stability of the magnetometer probe and the accuracy of the north direction pointing are improved, and therefore the accuracy of observation data is improved.

Description

technical field [0001] The invention relates to the technical field of geomagnetic field observation, in particular to an instrument fixing device for magnetic survey in water areas. Background technique [0002] Surface magnetic prospecting is a geophysical method and technology that studies geological structures and mineral resources or the distribution of other detection objects by observing and analyzing magnetic anomalies caused by magnetic differences in rocks, ores, or other detection objects. The magnetic anomaly it studies refers to the distortion of the geomagnetic field caused by the superimposition of the magnetic field generated by the detection object on the earth's own magnetic field. The cause of magnetic anomalies depends on the earth's magnetic field and rock (ore) magnetism, both of which are the physical basis of magnetic exploration. According to statistics, more than 80% of the magnetic iron deposits in China were discovered or expanded through the clu...
