Roaming type ocean seismograph

Abstract

The invention relates to a roaming type ocean seismograph. The roaming type ocean seismograph comprises a floating ball, a sensing and communication positioning module, an energy module, a low power consumption intelligent control module, and a buoyancy force adjusting module. The energy module and the low power consumption intelligent control module are disposed in the floating ball. The energy module is used to supply other modules with power. The low power consumption intelligent control module is used to process external information received by the sensing and communication positioning module. The sensing and communication positioning module is disposed on the top part of the floating ball, and the buoyancy force adjusting module is disposed on the bottom part of the floating ball. The roaming type ocean seismograph is different from a conventional fixed land seismic station and a conventional submersible ocean-bottom seismograph, and is floated in an ocean, and is used to carry out a floating motion along with ocean current, and therefore the roaming type ocean seismograph is used for the long-time recording of the information transmitted by an earthquake, and is used for recording of seismic signals received from different locations. A seismic network capable of covering a large ocean area is formed, and the problem of the lack of the seismic network in the ocean is solved, and the roaming type ocean seismograph is especially suitable for the tomography and the marine seismic observation of the large area ocean area.

Description

technical field [0001] The invention relates to a seismograph that can be used in the ocean, in particular to a roaming marine seismograph. Background technique [0002] Marine seismic monitoring is the most important means of studying the earth's structure, activities and processes. Large-scale, long-term monitoring of marine earthquakes with high temporal and spatial coverage is of great scientific significance for revealing the earth's structure, activities and processes. Much of our understanding of the Earth comes from the seismic waves generated by earthquakes that travel through the interior of the Earth to reach the surface and are observed. Seismic wave method is by far the most commonly used and most effective method for the study of earth structure, activity and process. Through the deployment of a large number of seismic stations, great achievements have been made in the study of the internal structure of the earth, but there are still different or contradictory...

Problems solved by technology

[0003] In addition to the cable seismic used by the offshore oil industry to target shallow water sediments, the most common marine seismic method for earth structure research is to use submarine seismographs. Only used for artificial source seismic experiments carried out for a short period of time

In addition, broadband submarine seismographs can also monitor natural earthquakes, but it is difficult to work on the seabed for more than one year, and because they are fixed-point observations and limited in number, they are far from meeting the observation requirements of large-scale seismic network in sea areas

[0004] Therefore, there is currently no marine seismic monitoring equipment with the advantages of simple deployment and recovery and low cost, which can be used for large-scale natural earthquake monitoring and global seismic tomography data collection.
