Rock-based seabed high-pressure submarine cable protection structure

The utility model relates to a rock-based seabed high-pressure submarine cable protection structure, which comprises a steel sleeve sleeved on the periphery of a high-pressure submarine cable, the steel sleeve is attached to the seabed surface of a rock base, and a broken stone canvas bag or a concrete block net quilt is covered on the steel sleeve. The protection structure can effectively preventthe submarine cable from moving, completely eradicate friction with bedrock and prevent external force damage, the safety of the submarine cable is greatly improved, the protection problem of the high-pressure submarine cable on a rock-based seabed with a shallow soft covering layer and exposed bedrock is solved, and the protection structure has decisive significance for large-scale development of the offshore wind power industry in China. 本实用新型涉及一种岩基海床高压海缆保护结构，包括套在高压海缆外围的钢套管，所述钢套管贴着岩基的海床面，所述钢套管上覆盖有碎石帆布袋或砼块网被。本实用新型保护结构可有效阻止海缆移动，杜绝与基岩产生摩擦，防止外力破坏，海缆安全性大大提高，解决在软质覆盖层较浅、基岩裸露的岩基海床上高压海缆的保护问题，对于我国海上风电产业的规模性开发具有决定性意义。
