Problems solved by technology

[0003] There are different solutions for drilling holes on the heave plate. One solution is to drill different numbers of holes with the same radius on the heave plate. The radius of the holes in this method is too rigid. Although the processing is simple, it cannot be further improved. Increase the stability of the platform; another solution is to drill holes with different radii on the heave plate, and arrange the punching positions on the heave plate based on individual subjective. The subjective choice of drilling is random drilling; in addition, only considering the air permeability of the heave plate to drill holes, this method is simple to consider and blind

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will specifically illustrate the fractal through-hole heave plate of the present invention in conjunction with the accompanying drawings.

[0021] figure 1 is a schematic diagram of a floating wind turbine and a heave plate, where a is a floating wind turbine equipped with a fractal graphic heave plate, and b is figure 1 Partial enlarged view of C in (a).

[0022] Fractal geometry is a discipline that takes irregular geometric forms as the research object, but its research objects are ubiquitous in nature, so it is called "the geometry of nature"; the application of fractal geometry is also to imitate nature Phenomena, like bionics, have received very good results. The theory of fractal geometry has good applications in many scientific fields. For example, the fractal surface structure heat exchanger not only improves the he...

Abstract

The invention relates to a fractal through hole heave plate, which has the following characteristics that the fractal through hole heave plate comprises a heave plate, wherein the heave plate is provided with a plurality of through holes vertical to a plate surface, and the plurality of through holes are arranged in a fractal mode. Since the plurality of through holes in the heave plate are arranged in the fractal mode, after the fractal through hole heave plate is installed on a floating platform, the fractal through hole heave plate has functions of increasing the damping of the floating platform and optimizing the response of the floating platform, and the stability of the floating platform is further improved.

Description

technical field [0001] The invention relates to a heave plate, in particular to a fractal through-hole heave plate. Background technique [0002] With the development of the wind energy industry, the development of offshore wind power has become an inevitable trend. Therefore, wind turbines also have a development trend from land to sea, from small to large, and from fixed to floating. For offshore floating wind turbines, the floating platform plays a supporting role. The surrounding of the offshore floating Spar platform is equipped with a mooring system so that the platform can be better positioned. In order to increase the stability of the platform, the heave plate is installed on the underwater part of the platform. The reference of the heave plate not only provides additional viscous damping for the overall structure, but also improves the overall structure’s stability. Additional quality; the heave plate can replace the Spar main body that depends on the large draft,...
