Load-adjustable deep sea umbilical cable stress release device

Abstract

The invention discloses a load-adjustable deep sea umbilical cable stress release device, which adopts a core structure comprising a suspender assembly, a fixed frame, a bidirectional hinge mechanism and drawer type balancing weights: the drawer type balancing weights adjust the total load to 30-40% of the safe working load SWL of an umbilical cable by increasing or decreasing the number of the balancing weights, and adapt to various umbilical cables of which the SWL is greater than or equal to 12.5 kN; the lifting lugs have the lifting function and the anti-oscillation function; the fixing frame is of a single-face open type anti-collision structure and can carry the deep-sea pressure-resistant monitoring cabin and the environment sensing unit, and pressure reduction through holes are formed in the tail ends of square pipes of the fixing frame to resist deep-sea high pressure. The two-way hinge mechanism achieves two-degree-of-freedom self-adaptive swing, ship shaking and ocean current impact are counteracted, and the vertical posture of the deep-sea umbilical cable stress releasing device is maintained. The device is compact in structure and convenient to assemble, the adaptability, reliability and safety of stress release of the deep sea umbilical cable can be remarkably improved, meanwhile, the functions of multiple balancing weights are integrated, and the operation complexity is reduced.
