Novel mooring cable suitable for non-contact power and data transmission

Abstract

The invention discloses a novel mooring cable suitable for non-contact power and data transmission. The novel mooring cable comprises an upper mooring cable body and a lower mooring cable body, wherein the upper end of the upper mooring cable body is sequentially connected with an upper watertight load-bearing device, a transmission cable and a watertight joint from bottom to top; the lower end of the lower mooring cable body is connected with a lower water-right load-bearing device; a trapezoidal branch structure is arranged between the upper mooring cable body and the lower mooring cable body and comprises an upper vulcanization branch node, an inner magnetic core cable and a lower vulcanization branch node, which are sequentially connected with one another from top to bottom; and an outer magnetic core cable is arranged between a side branch of the upper vulcanization branch node and the side branch of the lower vulcanization branch node. The novel mooring cable can ensure the stability of power transmission in an underwater environment through reducing the change of an inductance; and meanwhile, the cable is prevented from being wound due to the factors of flow and the like by a single cable structure.

Description

technical field [0001] The present invention relates to a mooring cable, more specifically, relates to a new type of mooring cable suitable for non-contact power and data transmission. Background technique [0002] The offshore ocean observation system is a long-term, all-weather, fully automatic series of large-scale automated ocean instruments and equipment, mainly composed of various buoys, submarine buoys, survey sections, offshore platforms, volunteer ships and satellites, etc. Stable operation at sea. The sensing systems used by various observation equipment to monitor ocean information are divided into two parts, one is the above-water sensor system, and the other is the underwater sensor system. [0003] At present, there are two methods of power supply for underwater sensors in marine observation systems: the first is self-capacitance power supply, that is, the battery carried by the underwater sensor itself supplies power for itself; the second is contact wire pow...

AI Technical Summary

Problems solved by technology

The observation system using self-contained power supply needs to salvage the underwater sensor system regularly and replace the battery for the underwater sensor system, which is a huge project.

The wire transmission method has the disadvantages that the line joint is easy to corrode, the impact of sea water will cause the joint to loosen or detach, the wire strength is low, and it will break under the long-term action of sea water.

The data transmission methods between the underwater sensor of the observation system and the observation platform include wire transmission, son
