Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture and photovoltaic floating raft equipment, in particular to an aquaculture and photovoltaic floating raft utilizing retired wind turbine blades. Background Art

[0002] With global climate change, reducing carbon emissions has become the most pressing issue today. Renewable energy development is one of the most effective means of addressing carbon emissions and reducing reliance on fossil energy. The number of renewable energy wind power generation installations has increased year by year, and the amount of thermosetting composite solid waste, such as retired wind turbine blades and nacelles, has increased dramatically. Wind turbine blades, fairings, and nacelles are large in size, and the thermosetting epoxy resin, glass fiber, and carbon fiber composite materials used in the blades are inherently non-biodegradable. Current methods of disposal, such as stacking, crushing, and burial, occupy significant land resources and are prone to environmental pollution. Disposing of these large quantities of retired thermosetting composite materials has become an urgent issue that needs to be addressed now and for some time to come.

[0003] According to the characteristics of thermosetting composite materials such as wind turbine blades, after completing the power generation task, retired wind turbine blades still have high durability - in terms of UV resistance, weathering resistance, corrosion resistance, fatigue resistance, high strength, light weight and other excellent properties. In addition, wind turbine blades are large in size, and the hollow space at the cylindrical root of the blades is large, and there is a large buoyancy. They have a broad application market in deep-sea aquaculture, wind and wave-resistant aquaculture equipment, and surface photovoltaic power stations.

[0004] At present, surface floating raft aquaculture cages and bare floating raft structures require a large number of floating bodies to maintain the floating state of the aquaculture raft structure on the water surface. The existing aquaculture rafts, as shown in technical proposal 202320732627.0, have a large size due to the hollow structure of wind turbine blades, which occupies a large storage space, is difficult to recycle and transport, and is expensive. The independent production of the floating bodies of the aquaculture equipment results in large material losses, and the floating bodies are still largely made of independently produced plastic materials or HDPE materials.
