A submarine cable traction protection tube for offshore wind power generation

Abstract

The invention discloses a submarine cable traction protection tube for offshore wind power generation, which belongs to the field of submarine cable protection tubes. A submarine cable traction protection tube for offshore wind power generation comprises a traction protection tube body fixedly installed on the upper end of a support steel Both the protective tube body and the upper inner wall of the extended half-arc protective tube are fixedly connected with multiple lubricating elastic expansion tubes, which can protect and flexibly buffer the submarine cable through the cooperation of the diameter-reducing sheath and the expansion and contraction bag, and limit the laying of the submarine cable. The change range of the bending radius during the process can effectively reduce the damage rate of its internal components, and through the expansion of the expansion and contraction bag, the diameter of the submarine cable can be reduced and the degree of freedom of the submarine cable can be reduced. When the submarine cable is subjected to various pressures and When shaking occurs under the influence of the environment, reduce the generation of vibration and reduce its lateral movement on the main body of the traction protective tube and the extended half-arc protective tube, thereby effectively reducing the impact force, reducing the damage caused by impact or friction, and improving the performance of the submarine cable in the sea. under the service life.

Description

technical field [0001] The invention relates to the field of submarine cable protection pipes, and more specifically relates to a submarine cable traction protection pipe for offshore wind power generation. Background technique [0002] In recent years, with the maturity of wind power technology, the offshore wind power industry has developed rapidly. In order to enhance the power supply reliability of offshore islands, my country has built a number of submarine cable transmission projects. In these cross-sea power transmission projects, submarine cables, as important equipment connecting substations or converter stations at both ends, play an important role in their production. The quality of submarine cable laying has an important impact on the life and efficiency of the entire power supply system. As offshore wind power projects get farther and farther from the shore, some large-scale and long-length submarine cables are used in power transmission projects, which puts fo...

Problems solved by technology

[0004] In the ship-out area where the submarine cable is laid, it is first guided and supported by the traction protection tube of the laying ship, and then pulled into the water by the tractor and connected with the submarine cable pre-embedded machine. The cable is very fragile. After entering the water, in addition to its own weight and the buoyancy of the seawater, it is also affected by waves, waves and currents, which makes it easy to pull the protective tube and collide during the laying process, increasing the damage of the cable. And it increases the difficulty of controlling the angle of entry of the submarine cable into the water, making it subject to further damage
