Description

OWC-integrated vertical-axis four-upright-column wind-light-fish integrated hybrid floating foundation Technical Field The invention belongs to the technical field of ocean engineering, and particularly relates to an OWC-integrated vertical-axis four-column wind-light-fish integrated hybrid floating foundation. Background The construction of a clean, low-carbon, safe and efficient modern energy system has become a global consensus. Along with the development of 'carbon reaching peak, carbon neutralization' targets, the development and utilization of ocean renewable energy sources such as wind energy, photovoltaic energy and wave energy gradually become an important direction of long-term energy strategic layout in coastal countries. The deep open sea area wind energy and wave energy are rich in resources, have the characteristics of high wind speed, low turbulence and high wave energy density, have large-scale development potential in theory, are limited by factors such as large water depth, complex environmental working conditions and the like, are difficult to be applied to a traditional fixed foundation, and become an important development trend of deep open sea development due to the floating wind power platform. However, there are still many restrictions in the deep sea development mode at this stage. On one hand, most floating platforms in the prior art have single functions and mostly only bear wind power generation functions, are insufficient in development and utilization of three-dimensional spaces above sea surface, at sea level and below sea surface, and do not realize collaborative development of multiple types of resources on the same basis, on the other hand, deep sea wind speed and solar irradiance have obvious time variability and instability, stability and reliability of power output are difficult to ensure only by wind power or photovoltaic power generation, and larger pressure is brought to grid connection and energy utilization sides. Wave energy utilization technologies such as oscillating water columns and the like show higher application potential in test and demonstration projects, but the existing OWC devices exist in an independent floating body mode, and are lower in degree of structural sharing and functional coupling with a large-scale floating wind power foundation, so that the overall cost is higher, the arrangement is dispersed, and the maintenance is complex. Meanwhile, fishery culture facilities such as deep-open sea net cages and the like generally need to independently construct floating bodies or fixed structures, are large in investment and limited in storm resistance, lack of integrated collaborative design with energy infrastructure, and do not form a unified platform carrier for comprehensive development of 'energy and fishery'. Most of existing deep open sea wind power, photovoltaic, wave energy and fishery cultivation are distributed, and OWC devices are difficult to realize integrated design with a floating foundation structure, so that the problems of repeated foundation construction, insufficient wave energy utilization and difficult consideration of overall stability and economy of a platform are caused.
