Description
Technical field
The present invention relates to underwater seismics field, the underwater seismics floating cable of specifically a kind of replaceable sensor.
Background technology
Underwater seismics cable is one of important component of underwater seismics.Existing underwater seismics electricity
Cable is the RAD towing cables and soft solid cable such as CNOOC of the liquid-filled cable such as SERCEL applied to marine seismic prospectiong mostly
, this cable mainly with to earthquake or focus generation underwater sound signal be acquired, and by collected data transmission to count
According in processing and record system.
Ocean seismic exploration haulage cable provides buoyancy using the liquid and soft solid filled in the cable for cable, and structure is stupid
Weight, involves great expense, what is mainly faced is main road number seafari operation.With the development that water conservancy and hydropower is explored, river and lake
Seismic exploration is more and more.The water flows gently with respect to marine seismic survey environment for river and lake seismic exploration environment,
Stormy waves is smaller, and job area is smaller, is suitable for trail number seismic survey system.Lightweight cable coordinates the river earthquake of trail number
Exploration system is more widely applied.The sensor of existing submerged cable is wrapped in floating cable, can not be replaced so that seismic prospecting
System may be only available for the applicable operating environment of current wave detector, reduce systematic difference range.In addition, sensor is wrapped in
In floating cable, across solid or liquid filler material, the sensitivity of sensor is reduced so that work data quality declines.
Invention content
The technical problem to be solved in the present invention is to provide a kind of underwater seismics floating cable of replaceable sensor, sensors
It is placed in the underwater sensitivity for improving acquisition, floating cable, which is suspended on the water surface, is convenient for alignment sensor and data transmission.
The technical scheme is that：
A kind of underwater seismics floating cable of replaceable sensor, it is characterised in that：Include floating cable ontology, be connected to floating cable sheet
Multiple sensor connectors on body and external row's sensor；The floating cable ontology includes outer jointing jacket, is set to
The soft solid that more piece in outer jointing jacket is transmitted core and is filled in outer jointing jacket, sensor connector includes T-socket
It is connect with the cable being connect with transmission core that is provided at both ends with of the transmission cable being set in T-socket, T-socket horizontal component
Mouthful, the end of T-socket vertical portion is provided with the sensor interface being connect with transmission cable, and floating cable ontology passes through multiple sensings
The horizontal component of device connector T-socket, the adjacent two ends of adjacent two section transmission cores reach outside outer jointing jacket and divide
It is not connected with two cable interfaces of corresponding sensor connector；One row's sensor respectively by corresponding transmission cable with
The sensor interface of respective sensor connector connects.
The outer jointing jacket selects polyurethane outer jointing jacket；The soft solid selects polyurethane elastomer.
The sensor interface of the sensor connector and the junction of transmission cable, sensor connector cable interface with
The junction for transmitting core is filled with waterproof gasket cement.
Advantages of the present invention：
（1）, floating cable ontology of the present invention soft solid have 0.75g/cm3Proportion, provides the floating support of entire floating cable, and
After floating cable outer jointing jacket breakage, soft solid can still be such that floating cable floats, and can be suitably used for various waters operations；
（2）, inventive sensor be placed outside outside floating cable, floating cable can according to job requirements more emat sensor, and replace facilitate it is fast
It is prompt；
（3）, sensor of the invention connect with sensor connector on floating cable ontology using transmission cable, ensure the underwater of sensor
Depth consistency is high, improves the quality of gathered data, and the depth under water of sensor can be adjusted according to the length of transmission cable
Section improves the application range of underwater seismics operation；
（4）, floating cable ontology of the present invention outer jointing jacket be polyurethane outer jointing jacket, have the advantages that waterproof and anticorrosion insulation, reduction
Corrosive effect of the flow to entire floating cable ontology；It smears waterproof gasket cement and carries out at waterproof in the junction of each interface of sensor
Reason, prevents the entrance of flow, to ensure that using effect, improve service life.
