Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] like figure 1 As shown, it is a three-dimensional structure diagram of the single-cabin ball three-component submarine magnetometer of the present invention, which is mainly composed of three parts: a decoupling mechanism 1 , an instrument cabin 2 and a base 6 . Place the instrument cabin 2 on the base 6, the safety ring 3 is installed in the middle of the instrument cabin 2, the decoupling mechanism 1 is placed at the top of the i...

Abstract

The invention discloses a single-cabin-ball three-component submarine magnetometer which comprises an unhooking mechanism, an instrument cabin and a base. An integrated packaging mode is adopted in the instrument cabin, and a three-component magnetic sensor, an orientation sensor, an attitude sensor and a data sensor are installed in the instrument cabin. The single-cabin-ball three-component submarine magnetometer is used for submarine magnetic field observation, oil-gas exploration and geological survey. A submarine magnetic field measurement function of the single-cabin-ball three-component submarine magnetometer is concentrated in a single cabin ball, and the problems that an existing submarine magnetic force detection device is complex and low in direction positioning precision and has inconvenience in placing and recycling operation and the like are solved.

Description

technical field [0001] The invention belongs to the field of geophysical measurement, in particular to the field of ocean surveying, and relates to a submarine magnetic field signal detection instrument. Background technique [0002] Marine electromagnetic exploration is one of the main marine geophysical exploration methods. It is suitable for areas where seismic methods are difficult to distinguish but electromagnetic methods have advantages, such as carbonate reefs, rock mounds, volcanic rock coverage, seafloor permafrost, etc. . Due to the complexity and high risk of mineral resource exploration in the sea area, the use of comprehensive geophysical acquisition to reduce risks and improve the success rate has become an important means for developed countries to carry out marine resource surveys. The combination of electromagnetic exploration and seismic exploration has a significant effect in reducing polysolution and reducing exploration risk. At the same time, in the ...
