Description

Technical Field

[0001] This utility model relates to the technical field of steel wire ropes for deep-sea exploration, specifically a composite structure anti-rotation steel wire rope for deep-sea exploration. Background Technology

[0002] Deep-sea exploration steel wire rope is a high-performance load-bearing component designed specifically for the extreme environment of the deep sea. It has characteristics such as high strength, corrosion resistance, fatigue resistance, and rotation resistance. Its structure is usually composed of multiple layers of steel wires or composite materials with different functions, such as load-bearing layer, anti-torsion layer, buffer energy-absorbing layer, and outer sheath layer. It is designed to withstand the high pressure, strong corrosion, and complex dynamic loads of the deep sea and is widely used in deep-sea resource exploration, marine engineering, seabed drilling, and scientific research to ensure the safe and reliable operation of operating equipment.

[0003] The deep-sea exploration environment is extremely complex, and high water pressure and strong corrosion are key factors affecting the performance of composite structure anti-rotation steel wire ropes used in deep-sea exploration.

[0004] As water depth increases, water pressure can reach tens to hundreds of megapascals, causing microscopic deformation of the internal structure of the wire rope, stress concentration, and reduced lubricant fluidity, thereby exacerbating friction and fatigue damage. At the same time, the deep-sea environment is rich in corrosive media such as chloride ions and sulfides, which can easily lead to pitting corrosion and stress corrosion cracking under long-term action, weakening the mechanical properties and service life of the wire rope. Although there are protective measures such as galvanizing, stainless steel coating, and special lubricants, they are still difficult to completely resist the combined effects of high pressure and strong corrosion in long-term deep-sea operations, resulting in insufficient environmental adaptability of the wire rope and limiting its reliable application in deep-sea exploration. Therefore, a composite structure anti-rotation deep-sea exploration wire rope is proposed to solve the problems mentioned above. Utility Model Content
