Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0016] A deep-water liquid level detection cable, including an outer sheath 1, an inner sheath 3, and an insulated wire core 8, the outer sheath and the inner sheath are coaxially installed, and a plurality of insulated wire cores are evenly distributed in the inner sheath. There are four insulated wire cores in the accompanying drawings, the insulating material of which is polyethylene, and an inner conductor 7 is coaxially installed in the insulated wire cores. The outer sheath is made of thick polyether polyurethane, and the inner sheath is made of polyethylene material with good water resistance.

[0017] The innovation point of the present invention is:

[0018] A steel wire reinforcement core ...

Abstract

The invention relates to a deepwater liquid level exploration cable which consists of four polyethylene insulated wire cores, one steel wire reinforcing core, an inner protective layer, woven aramid fiber reinforcing layers and an outer protective layer, wherein an aramid fiber filament is woven outside each polyethylene insulated wire core so that insulated core wires are not easy to break and the reliability of signal transmission is ensured. A central steel wire reinforcing core can bear all the weight of probe equipment and a cable so that the tensile strength of the cable is promoted; the inner protective layer adopts waterproof polyethylene to ensure that the cable is suitable for working in a deepwater environment for a long time; inner and outer woven aramid fiber reinforcing layers greatly enhance the tensile strength of the cable; and the outer protective layer adopts polyether type polyurethane, and the excellent chemical reagent resistance of the polyether type polyurethane ensures that the cable can work underwater for a long time.

Description

technical field [0001] The invention belongs to the field of cables, and relates to a detection cable, in particular to a deep water liquid level detection cable. Background technique [0002] With the development of science and technology, higher requirements are put forward for the depth of water level detection. But there is no special deep water detection cable on the market at present. [0003] Through retrieval, a relevant published patent document was found: a deep-water detection cable for offshore oil exploration (CN201838349U). It includes a cable core and a sheath layer. The cable core is composed of multiple conductors. A single conductor is covered with a polyperfluoroethylene insulation layer. The conductor is provided with a plastic-coated galvanized copper wire filler. The cable A rubber isolation layer is arranged outside the core, and an armored shielding layer is arranged outside the isolation layer, and the shielding layer is wrapped with non-woven fabr...
