Self-sinking and self-floating type broadband single/multi-cabin ball ocean bottom seismograph

Abstract

The invention discloses a self-sinking and self-floating type broadband single/multi-cabin ball ocean bottom seismograph, which comprises one or more glass instrument cabin balls and ballasting anchors arranged at the bottoms of the glass instrument cabin balls, wherein an underwater acoustic control circuit board, an all-attitude high-frequency detector, a GPS, a battery pack, an electronic compass and an underwater acoustic communication module are arranged in each glass instrument cabin ball. The seismograph is characterized in that a lifting control mechanism for recovering the glass instrument cabin balls is arranged between the glass instrument cabin balls and the ballasting anchors. The purpose of full-automatic buoyancy regulation and control is achieved, convenient use is achieved, the recovery efficiency and success rate of the ocean bottom seismograph can be improved, the recovery failure rate of the seismograph is reduced, and the purpose of full-automatic recovery is realized; and the mechanism adjusts the buoyancy by controlling the amount of seawater entering and exiting, so that compared with a traditional damage modes such as electro-corrosion and electric fusing,the mechanism not only reduces the maintenance amount of equipment, but also can be repeatedly used, thereby greatly reducing the use cost .

Description

technical field [0001] The invention relates to the technical field of marine observation instruments, in particular to a self-submerging and floating broadband single / multi-chamber spherical seabed seismograph. Background technique [0002] Ocean observation instruments are the general term for all instruments used for ocean observation, and are the basic tools for observing and measuring the ocean, usually referring to equipment such as sampling, measurement, observation, analysis, and data processing. Marine observation instruments are one of the high-tech fields that are technology-intensive, knowledge-intensive and capital-intensive, and are the backbone of the marine information industry. The correct understanding of the ocean comes from experimental observations. Every major discovery or progress in marine science research is closely related to the application of a new instrument. Advanced ocean observation instruments are crucial to the progress of ocean science. Oc...

AI Technical Summary

Problems solved by technology

[0007] It can be seen that although the current submarine seismograph technology can return to the sea surface from the seabed with the help of buoyancy to realize recovery, but using the above-mentioned several release methods, although fusing and electric corrosion can control the action of the release device and remove the heavy ballast , but it will damage part of the structure of the equipment. When it is used again, parts need to be replaced, and the disassembly is time-consuming and laborious. In some cases, when there are problems with fusing and electric corrosion, the action of the release device cannot be controlled. Since the equipment is on the seabed, it cannot be done manually. Operational control can only abandon the ocean observation instrument, resulting in the waste of expensive instruments
