Abstract

The invention discloses an ocean observation float mooring system and a mixed cable for the same. The mixed cable comprises a metal fiber mixed cable core and fiber cable skin, the metal fiber mixed cable core comprises a metal spiral spring and a fiber supporting core arranged inside the metal spiral spring, the fiber cable skin is formed by twisting and weaving multiple fiber cable strands, andmass content of the metal fiber mixed cable core is not greater than 20% of mass of the mixed cable while that of the fiber cable skin is not smaller than 80% of the mass of the mixed cable. The mixedcable is small in linear density and high in breaking strength, can serve as a data transmission channel between an underwater sensor and a water surface receiver, has the advantages of softness, light weight and easiness in laying that fiber mooring cables have and has good application prospect in the ocean observation float mooring system.

Description

technical field [0001] The application belongs to the technical field of fiber ropes, and in particular relates to a hybrid cable used for an ocean observation buoy mooring system and a buoy mooring system. Background technique [0002] Based on its long-term, continuous and unattended characteristics, ocean observation buoys are widely used and become the most important means of ocean environment observation. [0003] The mooring system is an important part of the ocean observation buoy. For example, the length of the mooring system of the deep-sea observation buoy can reach several kilometers. The lower part of the mooring system uses steel chains, the main mooring part in the middle part of the mooring system uses fiber cables, and the upper mooring part of the mooring system, that is, the underwater part of 0 to 1000 meters, uses mooring cables. For example, the mooring system of shallow sea observation buoys can also adopt a chain-cable hybrid structure. The lower part...
