Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the optical fiber seabed seismograph according to the first embodiment of the present invention. The working principle of the optical fiber seabed seismograph is that the fiber optic seabed seismograph is placed underwater and contacts the seabed through the coupling frame 50 . When there is a seismic wave signal, the coupling frame 50 will vibrate together with the seismic wave signal. The vibration is transmitted to the spherical shell 10 and transmitted to the fiber optic accelerometer 21 through the support member 31 and the support 30 , thereby causing the characteristics of the output light of the fiber optic accelerometer 21 to cha...

Abstract

The invention discloses an optical fiber ocean bottom seismograph which comprises a spherical shell (10), a support seat (30), at least one optical fiber accelerometer (21), a support element (31) and a coupling frame (50), wherein the spherical shell (10) is used for the internal structure protection of the optical fiber ocean bottom seismograph; the support seat (30) is installed in the spherical shell (10); the at least one optical fiber accelerometer (21) is installed on the support seat (30) and used for measuring an earthquake wave signal, and a tail fiber of each optical fiber accelerometer (21) is led out by an optical cable (22); the support element (31) is installed in the spherical shell (10) and used for mounting the support seat (30); and the coupling frame (50) is used for coupling the earthquake wave signal to the interior of the optical fiber ocean bottom seismograph and supporting and fixing the spherical shell (10). By utilizing the invention, the problems of complicated system, unavailable real-time transmission of the signal, low reliability, and the like of the traditional ocean bottom seismograph are solved.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to an optical fiber seabed seismograph. Background technique [0002] The submarine seismograph is an important equipment for marine geophysical exploration, and plays an important role in geophysical research, oil exploration, earthquake research and prediction. The United States, Britain, Japan and other countries have invested a lot of manpower and material resources in the development and application research of submarine seismographs. [0003] Most of the existing submarine seismometers are implemented by installing geophones, data recording equipment, power supplies, etc. in a high-strength glass chamber. For example, the patent "High Frequency Submarine Digital Seismograph" (ZL200410101868.7) filed by You Qingyu and others discloses a design scheme of a submarine seismograph, which uses a high-strength glass chamber to install a magnetic compass, data base, and b...
