Description

Deep-open sea multifunctional complementary and green cultivation integrated floating platform Technical Field The invention belongs to the technical field of design and construction of ocean platforms, and particularly relates to a deep-open sea multifunctional complementary and green cultivation integrated floating platform. Background With the growing shortage of landing land resources, space and resources are taken from deep and open sea as global strategic consensus. Among them, deep open sea renewable energy development and marine fishery cultivation are two development directions with great potential. However, these two fields face respective technical bottlenecks in the deep open sea environment at present, and are generally developed independently, and efficient synergy cannot be achieved. In the aspect of deep open sea energy development, mainstream technologies such as offshore wind power mainly adopt fixed foundation or single-function floating fans, the system has a single energy supply form, and is insufficient in power supply stability due to inherent intermittence and fluctuation of wind energy. Meanwhile, under the complex and severe wave load of the deep sea, the floating platform has obvious problems of pitching, rolling and heave motions, and influences the power generation efficiency and the structural safety of the fan. In order to improve stability, a structure is usually required to be reinforced or mooring is optimized, which leads to great cost rise, and in the aspect of marine fishery cultivation, the expansion to the deep sea is a necessary trend of expanding cultivation space and improving the quality of aquatic products. The deep-open sea cultivation has two major core limitations in long term, namely, the shortage of energy supply, difficulty in supporting continuous operation of intelligent equipment such as circulating water treatment, automatic feeding, environment monitoring and the like, restriction of scale and modernization, and the severe movement of a platform under the action of stormy waves, not only threatens the safety of cultivation facilities, but also is unfavorable for the growth of fishes. The existing cultivation platform is powered by a diesel generator, has high cost and heavy pollution, and the structural design mainly considers carrying cultivation load and has limited wind and wave resistance. To overcome the above challenges, the industry has begun to explore a wind-fish fusion model that combines offshore wind power with a farm platform. However, most current designs remain at the level of simple superposition or physical juxtaposition of functions. For example, fans and net cages are directly added on the basis of a semi-submersible platform, or the fans and net cages are combined through rigid connection. The scheme has obvious defects that firstly, an energy system is single and mainly depends on wind energy, the ocean renewable energy sources such as illumination, waves and the like are not comprehensively utilized, the multi-energy complementation cannot be formed, the reliability and the economy of energy supply are to be improved, and secondly, the system lacks coordination, and the dynamic coupling optimization among a platform structure, an energy device and a culture system cannot be realized. The traditional platform structure is not optimized for capturing wave energy, the culture net cage is only used as a passive load, a mechanism of potential damping effect for inhibiting platform movement is not effectively utilized, moreover, the intelligent and adaptability is insufficient, the photovoltaic panel lacks an adaptive adjustment mechanism for offshore illumination conditions, the mooring and anchoring system is mainly designed passively, and dynamic adjustment cannot be carried out according to the platform movement state and culture operation requirements. Therefore, how to provide a deep and open sea multifunctional complementary and green cultivation integrated floating platform, not only can realize comprehensive utilization and complementation of wind, light and wave multiple energy sources, but also can improve the overall stability through the coupled motion design of a platform structure and a cultivation system, thereby achieving deep coordination and intelligent regulation of an energy system, a structural system and the cultivation system. Disclosure of Invention Therefore, the invention aims to provide the deep-open sea multifunctional complementary and green cultivation integrated floating platform, which not only can realize comprehensive utilization and complementation of wind, light and wave multiple energy sources, but also can improve the overall stability through the coupled motion design of a platform structure and a cultivation system, thereby achieving depth coordination and intelligent regulation of an energy system, a structural system and the cultivation system. In order to achieve the above purpose, the present
