Abstract
The utility model relates to an ocean detection cable, and specifically relates to a novel ocean detection cable having floating and suspending functions in seawater. The cable comprises power line groups, signal line groups, transmission/auxiliary line groups, a tension layer, a buoyancy layer and an outer protection layer. Each power line group, each signal line group and each transmission/auxiliary line group are respectively covered with a small polyethylene sheath. All the power line groups are regularly arranged in the center of the cable. The signal line groups and the transmission/auxiliary line groups are alternately and circularly arranged on the periphery of the power line groups. The tension layer arranged outside the power line groups is composed of forward and reverse aramid fiber bundles by which the cable is prevented from being fractured due to pulling in the seawater. The buoyancy layer outside the signal line groups and the transmission/auxiliary line groups is made of a thickened foaming polyethylene layer having a high foaming coefficient. A polyurethane lining layer is arranged on the inner side of the buoyancy layer, and the polyurethane outer protection layer is arrange on the outer side of the buoyancy layer. The novel ocean detection cable is characterized by high electromagnetic compatibility, good air tightness, high tensile strength, wear resistance, corrosion resistance and biology invasion resistance.

The utility model content
The utility model is intended to solve the problems referred to above that existing marine exploration cable exists, and provide a kind of and have that Electro Magnetic Compatibility is strong, air-tightness good, tensile strength is large, the novel sea exploration cable of wear-resisting, corrosion-resistant, anti-biological invasion and attack.
The technical scheme that the utility model solves its technical problem employing is:
A kind of novel sea exploration cable, comprise source line group, signal line group, transmission/boost line group, tensile layer, the buoyancy layer, outer jacket, described every source line group, every supported signal line group, every transmission/boost line group all is surrounded by the little sheath of polyethylene outward, it is regularly arranged at the stranding center that all source line group are, signal line group and transmission/boost line group is alternately arranged and is circumferential arrangement in the source line group periphery, between source line group and signal line group and transmission/boost line group, the polyethylene liner layer of hard-pressed bale in all source line group outside from inside to outside successively, the tensile layer formed by forward and reverse Shu Fanglun, polyvinyl chloride lining as signal line group and transmission/boost line group bed course, the buoyancy layer of described signal line group and transmission/boost line group outside is the polyethylene foamed layer of the high-foaming coefficient of thickening, and buoyancy layer inboard is provided with the polyurethane lining, and buoyancy layer arranged outside has the polyurethane outer jacket.
Further, the core conductor in described source line group, signal line group and transmission/boost line group is tinned copper wire, and each core conductor insulation is the type that the extrudes polyethylene insulation that closely is extruded in core conductor outside.
Compared with prior art, the beneficial effects of the utility model are:
The circular little sheath of the polyethylene that source line group, signal line group, transmission line/boost line group itself increase can effectively improve the Electro Magnetic Compatibility of cable, reduces the cross-talk between the line group; Adopt forward and reverse Shu Fanglun tensile layer of high tensile performance, the metal anti-stretching part sea water resistance punching that more common marine cable adopts is pulled performance and is greatly improved, and can also reduce the burden of polyethylene foamed buoyancy layer simultaneously; The polyethylene foamed layer of the high-foaming coefficient of thickening, as the buoyancy equalizing layer of cable, by the budget to whole cable weight, is determined the thickness of foaming layer, makes the averag density of cable approach density of sea water; Adopt the polyurethane outer jacket to extrude compound sheath than metal embossing and the plastics of the most employing of current marine cable, can effectively solve watertightness, the resistance to chemical attack of cable, high strength, anti-biological invasion and attack performance.The utility model structure is merrily and lightheartedly reasonable, and weight metal only accounts for 8% left and right of cable gross weight, and sectional area accounts for the 1-2% of the cross-section of cable, and the weight metal of common marine cable accounts for the 15-35% of cable gross weight, and seabed even accounts for more than 60% with cable.
