Description

Technical Field

[0001] The present invention belongs to the technical field of submarine cable installation, and in particular relates to an offshore wind power submarine cable joint protection device. Background Art

[0002] Submarine cables are cables wrapped in insulating material, laid on the seabed, and used for telecommunication transmission. One end of the submarine cable of an offshore wind farm is connected to the wind turbine, and the other end is connected to a land-based substation or control center. An offshore substation or converter station may also be connected in the middle. The submarine cable plays the role of both "blood vessels" and "nerves" in the operating structure of the entire wind farm. In addition to collecting and transmitting electrical energy, it also has optical fiber units inside, which serve as channels for wind farm communications and submarine cable monitoring signals. There are many reasons for submarine cable failures, mainly fishing activities, anchor loss, sediment movement, laying operations, submarine cable suspension, fish bites, etc. Among them, fishing activities and anchor loss account for 70%. Submarine cable burial is another major cause. The submarine cable is buried at a shallow depth and is easily washed and suspended in the air, especially the submarine cable at the entrance of the wind turbine pile foundation. Long-term swinging causes damage to the submarine cable, and the location with the greatest impact on the submarine cable is the joint.
