Pileless self-stabilizing foundation for offshore wind power towers

Abstract

The invention relates to the field of new energy technology, in particular to a pileless self-stabilizing base of an offshore wind power tower, which includes a mounting column, the bottom of the mounting column is provided with a retractable support column, and the bottom of the support column is provided with a sealing cover. The bottom of the sealing cover is provided with a fixed anchor, and the outer walls of the upper and lower parts of the installation column are fixedly provided with a support plate, and the outer wall of the installation column is equipped with a support frame; the support column of the present invention is arranged in a shrinkable form, It does not take up space during transportation. During installation, pump water and air in the support column to form a support column, support below the water surface, reduce the overall center of gravity, improve stability, and the entire pile can be adjusted according to the ratio of water and air. The height of the body can adapt to the tide, and the flexible connection between the installation column and the support frame can maintain stability in the waves, reduce the shaking of the wind power tower itself, and improve the stability and reliability of the connection structure.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a pileless self-stabilizing base of an offshore wind power tower. Background technique [0002] As the world's energy becomes increasingly tense, wind power generation, as a source of new energy, is valued by countries all over the world. my country's sea area is vast and rich in wind energy resources, especially the development of wind power in offshore areas has huge economic value. Offshore wind power is different from inland wind power in that the construction of its tower foundation is difficult and is easily affected by the weather environment. At the same time, the existing offshore wind power has problems such as long manufacturing and installation cycle and difficult fixing. At present, the commonly used method is to manufacture wind power towers and their foundations inland, assemble the wind power towers and foundations into a single floating body that can float on...

Problems solved by technology

[0003] Therefore, the invention with the application number CN201510584627.0 discloses an offshore wind power tower foundation fixed by inflatable transport hydraulic piles, which is convenient for transportation and installation, reduces the amount of manufacturing and installation engineering, shortens the construction period, and ensures that the wind farm can be connected to the grid for power generation as soon as possible. However, this kind of tower foundation still needs concrete pouring and other operations to form fixed piles for support, which will not only affect the seawater environment during construction, but also require a lot of manpower and material resources for later demolition
