Offshore wind power single pile foundation embracing and centralizing device with rolling compensation

Abstract

The utility model relates to an offshore wind power single pile foundation hugging and centralizing device with rolling compensation type, which belongs to the technical field of offshore engineeringinstallation and is an auxiliary equipment on a ship. The device mainly comprises a tight ring structure, a swing frame structure, a fixed frame and a roll compensating hydraulic cylinder, and is mainly used for overcoming the influence of the rolling motion of the floating body when piling the floating wind power installation platform, and for tightening the single pile foundation of the wind power, guiding the falling point and controlling the verticality of the single pile foundation. In the past, the single-pile wind turbine foundation was installed on a fixed installation platform, whichwas fixed on the seabed with pile legs, and was little affected by the environmental load, but limited by the depth of the piling water. Floating mounting platform overcomes the limitation of mountingwater depth, but the stability of floating platform itself is low, which makes the accuracy of mounting point and verticality decrease. The invention overcomes the rolling motion of the floating bodythrough rolling compensation, adjusts the position of the pile body through a hydraulic actuator, and improves the installation precision of the floating installation.

Description

Technical field [0001] The patent of the invention relates to a rolling compensation type ocean wind power monopile foundation holding and centralizing device, which is an auxiliary equipment on board and belongs to the technical field of ocean engineering installation. It is mainly used to overcome the rolling motion of the floating body during the piling operation of a floating wind power installation platform Impact, hold tight, drop point guidance and verticality control of wind power single pile foundation. Background technique [0002] Offshore wind turbines are mechanical devices that use offshore wind resources to generate electricity. Under the situation of increasingly tense forms of oil resources, all coastal countries have set their sights on the ocean wind power field with huge potential. Now developed countries in the world have established a number of offshore wind power plants, and China has gradually increased its investment in offshore wind farm construction in...

AI Technical Summary

Problems solved by technology

The column of the wind turbine tower on land is fixed on the ground foundation. The construction of the ground foundation is relatively easy and the quality is easy to guarantee. However, in the marine environment, the fixed foundation needs to be provided by a cylindrical pile foundation inserted into the seabed. The pile foundation needs to pass through The floating crane is installed on the sea surface. The verticality of the pile foundation during the pile sinking process is an important indicator to ensure the normal operation of the wind turbine. Affected by the ocean wind, waves and currents, the pile foundation is easy to tilt during the installation process. To ensure the pile foundation After the foundation is installed and positioned, it has a high-precision verticality. It is necessary to use a clamping device to adjust the verticality of the pile foundation in real time to ensure the installation accuracy, safety and reliability of the pile foundation.
