Abstract

The invention discloses a double-cabin-ball combined undersea electromagnetic instrument. A double-cabin-ball vertical combined structure is adopted, an upper cabin ball is a hydroacoustic control cabin ball, and a lower cabin ball is an electromagnetic collecting cabin ball; through the double-cabin-ball combined mode, the utilization complexity of the spaces in the cabin balls is reduced, the cabin ball spaces can be reasonably utilized, the complete instrument gravity can be reasonably controlled, internal battery spaces are more abundant, one year or above of the sea leaving time and three months or above of the data recording time can be guaranteed, and optimization design on the working time and the self weight of the instrument is achieved. The complete instrument gravity position is reasonably controlled, therefore, the attitude stability and the resistance to undersea bottom currents in the instrument sinking process are guaranteed, and the long-term working stability and reliability of the instrument are improved. The double-cabin-ball combined undersea electromagnetic instrument reduces the requirements for working ships, can be put and taken back without using heavy machinery and is suitable for the fields of undersea ore resource exploration, marine geology structure investigation and the like.

Description

technical field [0001] The invention relates to the field of geophysics, in particular to the field of seabed detection, and relates to a double-chamber ball combined type seabed electromagnetic instrument, which is suitable for the needs of long-term seabed electromagnetic detection. Background technique [0002] On land, the electromagnetic method has become a mature geophysical method, especially suitable for areas where the seismic method is indistinguishable and the electromagnetic method has obvious advantages, including carbonate reefs, rock mounds, volcanic rock cover, and seabed permafrost. etc., can well give the electrical structure of the earth's interior. Due to the complex internal environment of the ocean and high requirements for instrument performance, the electromagnetic method has not entered the field of ocean exploration for a long time. With the development of electromagnetic theory and the progress of marine instruments, marine electromagnetic method ...
