Abstract
The invention provides a dynamic submarine cable and a preparation method and device of the dynamic submarine cable, and relates to the technical field of submarine cables. The dynamic submarine cable comprises an electric unit, an optical unit, a filling piece, an inner protective layer, an armor layer and an outer protective layer, wherein the outer protection layer comprises a smooth sleeve and a spiral thread, and the spiral thread spirally extends in the axial direction of the smooth sleeve and is used for restraining vortex-induced vibration. The preparation method of the dynamic submarine cable comprises the steps of providing an electric unit, an optical unit and a filling piece; preparing a submarine cable core; forming an inner protective layer wrapping the submarine cable core; forming an armor layer wrapping the inner protective layer; and forming an outer protective layer wrapping the armor layer. The preparation device of the dynamic submarine cable comprises an outer protective layer extrusion device. The spiral thread spirally extends in the axial direction of the smooth sleeve, vortex-induced vibration of the dynamic submarine cable can be prevented through the spiral thread, and then the engineering mounting and laying cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of submarine cables, in particular to a dynamic submarine cable, a preparation method of the dynamic submarine cable and a device thereof. Background technique [0002] As wind turbines gradually go to the deep sea, floating wind power has become the development trend of offshore wind power. Foreign wind power developers and related institutions in Scotland, Japan, France and other countries have put into operation a few test prototypes since 2009. In recent years, Chinese wind power operators and submarine cable manufacturers have also carried out basic research on dynamic submarine cables. The dynamic submarine cable is in a complex deep-sea environment and is plagued by various safety hazards. Vortex-induced vibration is the most important one. The vortex generated alternately by the sides is an important factor that causes fatigue damage of dynamic submarine cables. [0003] In related technologies, sp...
