Description
Technical field
The present invention relates to submarine earthquake monitoring field, particularly relate to a kind of submarine seismograph and sink coupling frame, be applicable to submarine seismograph in use with being coupled of seabed.
Background technology
Submarine seismograph seismograph is placed on the instrument that seismological observation is carried out in seabed.During for observing earthquake, can help to carry out earthquake pre-warning, tsunami early warning, reducing the people's life and property loss because geologic hazard causes.Submarine seismograph also may be used for ocean oil and gas resource exploration.Utilize artificial excitation's seismic signal, utilize submarine seismograph to carry out seismic event collection, thus determine the position of hydrocarbon-bearing pool.
The quality of coupling effect to seismic data in submarine seismograph and seabed is most important.The main two kinds of modes adopted are at present: one, direct for submarine seismograph cloth is placed on seabed, laying of such as bay cable.The advantage of this way is simple to operate, and cost is low, but coupling effect is poor, runs into trench, trough and then likely makes submarine seismograph normally work.Two, heavy coupling frame is adopted to lay submarine seismograph.Although this mode operation is slightly complicated, coupling effect is good, very crucial for needing the submarine seismograph of long term monitoring or deep-sea to lay.
Current submarine seismograph sinks coupling frame and generally adopts angle bar to be welded, and is strapped on heavy coupling frame by submarine seismograph wire rope.Treat that seismic signal collection terminates, submarine seismograph is risen to sea by the ball float adopting winch or submarine seismograph to carry.
Current submarine seismograph sink coupling frame exist subject matter be, the first, the balance in sinking watching is restive.Submarine seismograph has the danger of toppling in sinking watching, thus causes submarine seismograph normally to work.The second, current submarine seismograph sinks coupling frame and submarine seismograph cannot be laid according to north-south.After submarine seismograph sinks to seabed, cannot accurately judge its deflection, the data collected like this cannot provide available information.Current solution is, adopts the mode of " secondary calibration " to judge the position angle of submarine seismograph.Namely adopt and manually blow out in fixed position, the data according to seismograph collection carry out azimuth calibration.The precision of such calibration is very low.Also have and adopt the mode of seafloor robot to calibrate position angle.The cost of such calibration is very high, and operating risk is very big.
Therefore, ensure submarine seismograph and seabed be coupled good while, guarantee submarine seismograph do not topple in sinking and the position angle ensureing submarine seismograph as far as possible accurately, become during current submarine seismograph is applied the problem needing solution badly.
The present invention proposes a kind of submarine seismograph and sinks coupling frame, for being coupled of submarine seismograph and seabed, emphasis solve ensure submarine seismograph and seabed be coupled good while, guarantee that submarine seismograph does not topple and ensures to try one's best problem accurately in the position angle of submarine seismograph in sinking.
