Embodiment 1

[0034] Example 1, such as Figure 1-6 As shown, a submarine seismic monitoring device is a horizontal structure, including an earthquake detection unit 1, and the earthquake detection unit 1 includes an instrument compartment 11 and a left conversion compartment 12 connected to the left and right ends of the instrument compartment, respectively. And the right conversion bin 13, the left conversion bin 12 and the right conversion bin 13 are spliced ​​with the instrument bin 11 to form a detection bin structure, the instrument bin 11 has an earthquake monitoring sensor 4, the left conversion bin 12 and the right conversion bin 13 is not only a transfer station for subsequent optical cable conversion, but also further improves and protects the structural stability of the entire monitoring device, ensuring the balance of the left and right sides of the instrument compartment 11.

[0035] Further, a left first photoelectric joint 121 and a left second photoelectric joint 122 are re...

Embodiment 2

[0047] Example 2, such as Figure 1-6 As shown, a chain-type submarine seismic monitoring device, this embodiment can adopt all the structures of embodiment 1, is also a more optimized application device derived from embodiment 1, and is suitable for use in sea areas with more different environments.

[0048] Specifically, it includes more than two seismic detection units 1, and all the seismic detection units 1 are connected in series to form a monitoring chain, and the adjacent seismic detection units 1 are connected by an external photoelectric composite cable 2. Through this series connection, and using The outer photoelectric composite cable 2 is arranged in a linear array, and the seismic detection unit 1 at each position can monitor and share data through the outer photoelectric composite cable 2, which not only constitutes a structurally stable monitoring chain system, but also realizes data sharing. Sharing and transportation can be applied to a wider range of seabed ...

Abstract

The invention relates to the technical field of ocean exploration, in particular to a chain type submarine earthquake monitoring device which comprises more than two earthquake detection units, all the earthquake detection units are connected in series to form a monitoring chain, and the adjacent earthquake detection units are connected through outer photoelectric composite cables.

Description

technical field [0001] The invention relates to the technical field of ocean detection, in particular to a chain-type submarine seismic monitoring device. Background technique [0002] A submarine seismograph is an instrument placed on the seabed for natural or artificial earthquake monitoring. You Qingyu and others disclosed the high-frequency submarine digital seismograph ZL200410101868.7, which is a spherical seismometer with a recovery device and sink coupling. In 2011, a similar 7-channel multi-functional submarine seismograph was obtained. In 2017, a similar low-power broadband seismometer was proposed. Single-chamber spherical ocean bottom seismograph. Zhuang Cantao and others disclosed a broadband submarine seismograph 200910093585.5, which is also a spherical seismograph with a recovery device and sink coupling. Most of the seabed seismometers that have been disclosed or in use are self-recovery seabed seismometers placed on the seabed. With the development of ma...
