Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation equipment, and in particular to a dedicated offshore wind power frame. Background Art

[0002] Offshore wind farms have high wind speeds, high wind quality, low turbulence intensity, and save land resources. Clean, safe, and sustainable offshore wind power plays an increasingly important role in the energy strategies of countries around the world, providing strong support for the development of a global low-carbon economy. It has become an important choice for mankind to cope with future climate change and potential energy crises, and has broad development prospects.

[0003] The bearing capacity of offshore wind turbine foundations is changing as water scours the soil around them. At the same time, the horizontal bearing capacity of the foundation will decrease as the scouring pit expands. Once the bearing capacity of the foundation is insufficient to support the normal operation of the offshore wind turbine due to the continuous expansion of the scouring pit, the entire offshore wind turbine will become unstable, causing huge economic losses. Therefore, it is of great significance to protect the wind turbine pile foundation from scouring. At present, most offshore wind turbine piles are installed in parts by cranes, but there are certain differences in the alignment accuracy during the installation process, so a pile structure that prevents misalignment is needed.
