Description

Technical Field

[0001] The utility model relates to the technical field of duct structures, in particular to a rectangular aquaculture floating raft structure 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, retired wind turbine blades after completing their power generation tasks still have high durability - with excellent properties such as UV resistance, weathering resistance, corrosion resistance, fatigue resistance, high strength, and light weight. In addition, wind turbine blades are large in size, with a large hollow space at the cylindrical root of the blades, and have large buoyancy, which has a broad application market in deep-sea aquaculture, wind and wave-resistant aquaculture equipment, and surface photovoltaic power stations.

[0004] Cage aquaculture and floating raft structures require a large number of floating bodies to maintain the floating state of the aquaculture raft structure on the water surface. However, the existing aquaculture rafts, as shown in technical proposal 202320732627.0, still use a large number of independently manufactured plastic floating body structures. The special independent manufacture of the floating body has the problem of large material loss and high transportation cost. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide a rectangular aquaculture raft structure using retired wind turbine blades to solve the problem that the independently manufactured plastic floating body structure in the existing technology has large material loss and high transportation cost.

[0007] The main body includes a wind turbine blade root, a wind turbine blade main beam, and a through socket. The wind turbine blade root is connected to the wind turbine blade main beam. A plug hole is provided on the wind turbine blade root. The through socket is connected to the plug hole of the wind turbine blade root. The through socket is provided with a main beam assembly area. The wind turbine blade main beam is plugged into the main beam assembly area of ​​the through socket and connected to the main beam assembly area.

[0008] One end of the anchoring device is connected to the body, and the other end is connected to the seabed;

[0009] The breeding device is connected to the main body or the anchoring device and is arranged below a rectangular floating raft structure formed by connecting four main bodies end to end.

In conjunction with the fixation of the anchoring device, the breeding device can be placed in the water body below the main body, and the main body of the rectangular structure is convenient for multiple arrangements and connections to form a breeding area, which effectively utilizes the buoyancy and structural strength of the hollow structure of the wind turbine blade, and is reused and put into the breeding field, reducing the processing cost of scrapped wind turbine blades and the manufacturing, transportation and time costs of breeding equipment.

[0011] As a preferred embodiment of the present application, the device further includes a Zhan-type hook, which is respectively provided at the root of the wind turbine blade and the main beam of the wind turbine blade of the main body.

[0012] As a preferred embodiment of the present application, a load-bearing panel is also included. The load-bearing panel is made of wind turbine blade skin and is connected to the main beam of the wind turbine blade. By using the wind turbine blade skin as the load-bearing panel, the cut wind turbine skin can be easily moved to the wind turbine blade main beam above the water surface to serve as a platform for carrying objects or people.

[0013] As a preferred embodiment of the present application, the wind turbine blade skin is an arc-shaped structure, and the middle part of the wind turbine blade skin is arched upward. By setting the wind turbine blade skin as an arc-shaped structure with the middle part arched upward, the accumulation of water can be prevented from affecting the buoyancy of the main body.

[0014] As a preferred embodiment of the present application, the anchoring device is a cable.

[0015] In a preferred embodiment of the present application, the anchoring device comprises a longitudinal cable and a diagonal cable, and the aquaculture device is a fish cage that is slidably connected to the longitudinal cable of the anchoring device.

[0018] As a preferred embodiment of the present application, the through-hole socket is a cylindrical structure. This increases the connection area and structural strength of the wind turbine blade main beam. When the through-hole socket is larger than the base, it facilitates quick docking and improves connection efficiency.

[0019] As a preferred embodiment of the present application, a root sealing plate is further included, wherein the root sealing plate is connected to the root of the wind turbine blade of the main body. By providing the root sealing plate, the root of the wind turbine blade can be easily sealed. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The breeding device 30 is connected to the main body 10 and is arranged below a rectangular floating raft structure formed by connecting four main bodies 10 end to end.

[0047] According to the above structure, during the actual application of the rectangular aquaculture raft structure using retired wind turbine blades, the replaced wind turbine blades on the wind turbine platform are placed nearby and processed. After directly drilling a hole in the wind turbine blade root 11 and cutting the wind turbine blade skin, the wind turbine blade root 11 and wind turbine blade main beam 12 are retained as the main body 10 structure. Subsequently, the through socket 13 is inserted into the plug hole of the wind turbine blade root 11.
