Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power installation, in particular to a transportation and storage rack for a wind turbine tower barrel. Background Art

[0002] As a clean and harmless renewable energy source, wind energy has been increasingly valued by humans. Among them, compared with onshore wind energy, offshore wind energy resources not only have higher wind speeds, but also are farther from the coastline, are not affected by noise limits, and allow for the manufacture of larger-scale wind turbine units.

[0003] An offshore wind turbine generator set (hereinafter referred to as an offshore wind turbine or an offshore wind machine) is a new type of power generation equipment that utilizes offshore wind energy resources. It usually includes wind blades (i.e., wind power generation blades), a wind turbine head (i.e., a wind wheel and a nacelle), a wind turbine tower barrel, and a foundation. Among them, the foundation is arranged at the bottom of the sea and is used to support and fix the tower barrel, which plays a crucial role in the overall safety of the offshore wind turbine generator set. The bottom end of the wind turbine tower barrel is fixed on the foundation, and the top end thereof is fixed with a wind turbine head, and the wind turbine head is used to install a plurality of wind blades and drive the rotation of the wind blades through wind energy, so as to realize the utilization of wind energy.

[0004] Due to the complex and changeable offshore environment, the installation of offshore wind turbine generator sets from foundation construction to overall installation is much more difficult than that of onshore wind turbine generator sets. Therefore, whether the offshore wind turbine generator set has good flexibility and adaptability in aspects such as foundation construction and overall installation is an important index for evaluating its excellent performance.

[0005] Currently, the main installation method of existing offshore wind turbine generator sets is offshore overall installation, that is, first assembling the components of the wind turbine generator set except the foundation at the onshore assembly base, then transporting them to the offshore proposed wind farm through a wind power installation platform or a crane ship, and finally installing the assembled components of the wind turbine generator set on the foundation located offshore. The above installation method is divided into an onshore installation stage and an offshore installation stage. Among them, although the onshore installation stage can reduce the installation difficulty of the offshore wind turbine generator set to a certain extent, the requirement for the lifting weight of the installation crane in the offshore installation stage is extremely high, the lifting cost is also very high, and the applicable lifting working conditions are very limited.

[0006] Therefore, in order to reduce the requirement for the lifting weight of the installation crane and the lifting cost in the offshore installation stage, some offshore engineering enterprises have begun to try to transport the components of the offshore wind turbine generator set to the vicinity of the designated offshore foundation through an offshore installation ship first, and then directly complete the entire process of installing the offshore wind turbine generator set offshore. However, since the storage rack for storing the wind power tower barrel in the current offshore installation ship is still a fixed storage rack used on land and lacks the structural design for the transportation process, it is not conducive to the handling of the tower barrel.
