Underwater floating type cable

Abstract

The invention provides a floating cable in water, which comprises an outer sheath unit, and a cable unit, an optical fiber unit, a communication unit and a buoyancy unit which are bundled in the outer sheath unit, the buoyancy unit is a hollow fluorine plastic pipe, and a layer of novel hollow microsphere compound sizing material is extruded outside the buoyancy unit. The composite rubber material is arranged in the outer sheath unit. And the outer sheath unit is made of extruded luminous hydrogenated butadiene-acrylonitrile rubber. According to the underwater floating cable provided by the invention, the ocean umbilical cable floats on the sea surface, the cost is low, and the functions of power, control and signal transmission feedback can be provided.

Description

technical field [0001] The patent of the present invention relates to the technical field of cables, in particular to a floating cable in water. Background technique [0002] In recent years, marine new energy power plants (photovoltaic, wind, tidal energy, tidal energy, wave energy), seawater pumped storage power stations, seawater desalination plants, marine seismic monitoring networks, submarine archaeological salvage, military, marine scientific research, offshore oil New industries such as exploration and offshore operation platforms are booming. The introduction of new technologies and new requirements in these emerging industries has put forward higher requirements for signal and power connection systems. [0003] For example, the use of the original marine umbilical cables and submarine cables in these emerging industries has exposed many deficiencies. The cables are too heavy, which will generate huge drag force on the mobile equipment operating on the surface or un...

AI Technical Summary

Problems solved by technology

[0003] For example, the use of the original marine umbilical cables and submarine cables in these emerging industries has exposed many shortcomings. The cables are too heavy, which will generate a huge drag force on the mobile equipment operating on the water surface or underwater, and may drag the equipment down. Heavy, it may cause excessive load damage to the equipment, and it may also cause the connector to loosen and enter the water, which will cause a short circuit and burn the equipment

When these marine umbilical cables and submarine cables are in the water or at the bottom of the sea, because they are submerged in the water surface, they are entangled with each other, hooked on equipment or underwater objects, and the staff cannot see them, and they may be pulled hard further and cause breakage or damage. or serious damage to equipment

[0004] At present, umbilical cable products do not perform well in low temperature environments. They become hard and brittle at low temperatures, and they are easy to crack when bent, and even cannot be opened to work in low temperature environments. performance requirements
