Description

The telemetry cable of submarine earthquake exploration

The utility model belongs to the marine resources exploration and development and measures the cable technology field, is mainly used in marine exploration and development of resources.

In the marine resources exploration and development, two dimension or 3D seismic data collection all will be used the ocean cable, and the ocean cable in the seabed that fixedly is laid in is exactly a kind of submarine cable, as is used for the sea electric power cable of electric power transfer, is used for submarine communication cable of signal transmission or the like.The seabed telemetry cable and the marine exploration ship that are used for marine seismic prospectiong connect together, and become a kind of portable submarine cable.Electronic metering equipment on detecting ship of ining succession of the submarine cable that this on-fixed lays, and in succession at acquisition station, hydrophone and the wave detector in seabed in the other end.

The telemetry cable that is used for land seismic prospecting, because of cable water pressure resistance not itself, no water-proof function, anti-corrosive properly difference and defective such as not wear-resistant and can't be used for marine seismic prospectiong have also limited its scope of application because of reasons such as the intensity of cable own are lower simultaneously.Therefore, still do not have at present a kind of telemetry cable that is used for the submarine earthquake exploration, it is good that it can satisfy water-stop, anticorrosion, wear-resistant, intensity is high and specific (special) requirements such as transmission signals bandwidth, to adapt to seafari and 3D seismic data collection needs.

The purpose of this utility model be to provide a kind of water pressure resistance, anticorrosion, wear-resistant, water-stop is good, intensity is high, transmission signals bandwidth and can sink to the telemetry cable that the on-fixed in seabed lays.

The utility model is realized as follows.

Can design a finished cable, its two ends are connected by watertight connector, taper rubber case and cable, and the centre axially can be extracted the plurality of sensors line out every certain-length along cable, form the several watertight tap, to insert corresponding transducer.

The watertight connector at finished cable two ends is to be used for earthquake data acquisition parts or control assembly are connected with cable; the taper rubber case is to be used for protecting watertight connector and cable; cable passes line, pickup wire by central reinforce member, number and power line is stranded forms, and the insulating material that extrudes two-layer anticorrosion, wear-resistant and function admirable in its outside again is as cable covering.

The utility model has following advantage.

The utility model is compared with telecommunication cable with the power cable in the existing seabed that fixedly is laid in has high strength, can transmit the earthquake data acquisition signal and the characteristics of power supply of broad frequency band simultaneously, and non-leakage when under 200 meters seabeds of the depth of water, working, do not drift about and advantages such as removable use and flexible take-up, compare with existing land seismic prospecting telemetry cable also have water pressure resistance, anticorrosion, characteristics such as wear-resistant.
