A dynamic composite cable pulling protection head

Abstract

The invention discloses a traction protection head of a dynamic composite cable. The traction protection head comprises a traction head having an untwisting function, a flexible hose, a traction hose terminal and an anchoring structure, wherein one end of the flexible hose is fixedly connected with the traction head, the other end of the flexible hose is connected with the traction hose terminal, the anchoring structure is fixedly connected with the traction hose terminal, a divisional sheath is arranged at a position whether the anchoring structure and the traction hose terminal are connected, a plurality of holes are formed in the divisional sheath, and the interior of the anchoring structure is of an inverted conical structure; and after a dynamic cable enters the anchoring structure, an outer sheath of the dynamic cable is stripped off, armored steel wires are dispersed around, and an inner sheath and a cable core extend out of the other end of the anchoring structure and pass through the divisional sheath to enter the flexible hose. The flexible traction protection head provided by the invention can be used repeatedly, the installation efficiency in the same power generator group is improved, and the installation cost is reduced.

Description

technical field [0001] The invention belongs to the field of marine new energy development, and in particular relates to a hose traction protection head for protecting a floating wind power generator during the dynamic cable traction and installation process. Background technique [0002] Onshore grid-connected wind turbines have been operating safely and stably for more than 20 years, and wind farms with excellent wind resources are close to saturation. Wind energy development is gradually shifting from land to sea, but offshore waters are planned to be mainly used for ports and aquaculture, so the main distribution of wind farms in the future will gradually move to deep sea areas. The biggest difference between the construction of deep-sea regional wind farms and land-based wind farms lies in the foundation of the wind turbines. Based on the particularity of the deep-sea seabed and wind conditions, a floating structure is required as the foundation of the wind turbines. ...

AI Technical Summary

Problems solved by technology

[0005] Purpose of the invention: The purpose of the present invention is to solve the problem that the dynamic cable used in the floating wind turbine in the prior art is pulled by the J tube in the floating foundation due to its high bending stiffness, which is difficult to bend and is easily affected by waves and moisture. Insufficient electrical performance, provide a flexible pipe with a back-twisting traction head for traction protection, which not only improves the efficiency of dynamic cable installation, but also better protects the electrical performance. At the same time, the protection tube can be easily disassembled and reused
