Description

Technical Field

[0001] This invention belongs to the field of marine platform design and construction technology, and specifically relates to a floating platform integrating deep-sea multi-energy complementarity and green aquaculture. Background Technology

[0002] With increasingly scarce land resources, seeking space and resources from the deep sea has become a global strategic consensus. Among these, the development of renewable energy in the deep sea and marine aquaculture are two highly promising directions. However, these two fields currently face their own technological bottlenecks in the deep sea environment and are typically developed independently, failing to achieve efficient synergy.

[0003] In deep-sea energy development, mainstream technologies such as offshore wind power mainly employ fixed foundations or single-function floating turbines. These systems offer limited energy supply and suffer from insufficient power stability due to the inherent intermittency and volatility of wind energy. Furthermore, floating platforms experience significant pitching, rolling, and heaving motions under the complex and harsh wave loads of the deep sea, affecting turbine power generation efficiency and structural safety. Improving stability typically requires structural reinforcement or mooring optimization, which significantly increases costs. In marine aquaculture, expanding into deep seas is an inevitable trend for increasing aquaculture space and improving the quality of aquatic products. However, deep-sea aquaculture has long faced two major constraints: first, a shortage of energy supply makes it difficult to support the continuous operation of intelligent equipment such as circulating water treatment, automated feeding, and environmental monitoring, hindering large-scale and modern development; second, the violent movement of platforms under wind and waves not only threatens the safety of aquaculture facilities but also harms fish growth. Existing aquaculture platforms mostly rely on diesel generators for power, resulting in high costs and heavy pollution, and their structural design primarily considers bearing the aquaculture load, limiting their resistance to wind and waves.

[0004] To overcome these challenges, the industry has begun exploring integrated wind and aquaculture models that combine offshore wind power with aquaculture platforms. However, most current designs remain at the level of simple functional superposition or physical juxtaposition. For example, wind turbines and net cages are directly added to a semi-submersible platform, or the two are combined through a rigid connection. These solutions have significant shortcomings: First, the energy system is singular, relying mainly on wind energy and failing to comprehensively utilize equally abundant marine renewable energy sources such as sunlight and waves, thus failing to achieve multi-energy complementarity, and the reliability and economy of energy supply need to be improved. Second, the system lacks synergy; the platform structure, energy devices, and aquaculture system have not achieved dynamic coupling optimization. Traditional platform structures are not optimized for wave energy capture, and aquaculture net cages are only used as passive loads, with their potential damping effect for suppressing platform movement not being effectively utilized. Third, there is insufficient intelligence and adaptability; photovoltaic panels lack adaptive adjustment mechanisms for marine lighting conditions, and mooring and anchoring systems are mostly passively designed, unable to dynamically adjust according to the platform's movement status and aquaculture operation requirements.

[0005] Therefore, the question is how to provide a floating platform that integrates deep-sea multi-energy complementarity and green aquaculture, which can not only realize the comprehensive utilization and complementarity of multiple energy sources such as wind, solar and wave, but also improve the overall stability through the coupled motion design of the platform structure and aquaculture system, thereby achieving deep synergy and intelligent control of the energy system, structural system and aquaculture system.

[0046] Compared with existing technologies, the deep-sea multi-energy complementary and green aquaculture integrated floating platform disclosed in the embodiments of the present invention has the following technical effects:

[0047] 1) This invention integrates a dual-head wind turbine, a photovoltaic power generation device 4, and a wave power generation device 5 on the same platform to construct an integrated complementary power generation system of wind, solar, and wave. The three energy sources are naturally complementary in time and space, effectively smoothing the fluctuation of total power output.

[0048] 2) This invention deeply integrates the two major functions of clean energy production and aquaculture, constructing a three-dimensional spatial layout with power generation above, a stable body in the middle, and aquaculture below. This integrated design can avoid the fragmentation and occupation of the sea area by a single-function platform, and realize the comprehensive sharing of sea area space, power facilities, and operation and maintenance resources.

[0053] As a specific embodiment of the present invention, the dual-head wind turbine device disclosed in the present invention includes a first wind power generation mechanism 2 and a second wind power generation mechanism 3. The first wind power generation mechanism 2 includes a first wind turbine assembly and a first tower assembly. The first wind turbine assembly is fixed to any two floats 1 through the first tower assembly. The second wind power generation mechanism 3 includes a second wind turbine assembly and a second tower assembly. The second wind turbine assembly is fixed to any two floats 1 through the second tower assembly. The first wind power generation mechanism 2 and the second wind power generation mechanism 3 are connected by a cable 8.

[0054] With this configuration, the first and second tower components of the dual-head wind turbine are supported on the pontoons 1 and connected by cables 8, forming a high-strength spatial triangular truss structure above the platform. This structure not only improves the rigidity and fatigue resistance of the dual-head wind turbine itself, but also effectively distributes the load of the first and second wind turbine components to multiple pontoons 1, thereby greatly enhancing the overall structural integrity and anti-overturning capability of the platform.

[0055] The embodiments of the present invention do not limit the specific structure of the first tower assembly and the second tower assembly. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

At least one pontoon 1 is simultaneously fixed with a first tower 23 and a second tower 33.

[0057] The two first towers 23, the two second towers 33, and the three pontoons 1 form a rigid frame structure that is highly coupled in space. Through the layout of four-point support and three-point interconnection, wind loads and wave loads from any direction can be quickly transferred and redistributed among the multiple pontoons 1 through the rigid frame, transforming concentrated loads into internal forces of the system. This structural configuration can greatly enhance the platform's ability to resist the huge overturning moment caused by the wind turbine, thereby effectively improving the structural safety and survivability under extreme wind and wave conditions.

It is one of the key support structures for achieving efficient synergistic integration of wind, solar, and wave propagation in this embodiment of the invention.

[0061] As a further embodiment, in the deep-sea multi-energy complementary and green aquaculture integrated floating platform disclosed in this embodiment of the invention, there is an included angle α between the pontoon 1 and the tower, and the preset angle α is 60° to 80°.

[0064] The servo motor is started, and its output shaft drives the photovoltaic panel to rotate on the cross brace, ensuring that its incident angle is always as perpendicular as possible to the sunlight, thereby maximizing energy capture and significantly improving power generation efficiency.
