Description

Technical Field

[0001] The utility model relates to the technical field of suction pile structures, in particular to a suction pile using retired wind turbine blades. Background Art

[0002] According to the characteristics of thermosetting composites such as wind turbine blades, retired wind turbine blades still have high durability after completing the power generation task --- excellent characteristics such as ultraviolet resistance, weather resistance, corrosion resistance, fatigue resistance, high strength, and light weight. Moreover, the wind turbine blades are large in size, and the hollow space in the cylindrical root of the blade is large, which has a broad application market in deep-sea aquaculture, anti-wave aquaculture equipment, and floating solar power plants on the water surface.

[0003] The technical solutions adopted by current suction piles are shown in 201410080258.7. Most of the existing suction bucket piles are made of steel and are mainly installed underwater. The steel barrels need to be treated with anti-corrosion in seawater, and the anti-corrosion materials are likely to have a negative impact on marine organisms. Moreover, the underwater part of the pile body cannot be treated with secondary anti-corrosion after installation. Under the action of ocean currents, the seabed surface turbulence is likely to cause scouring corrosion and suspension instability to the pile foundation. If not treated in time over time, it is likely to cause pile breaking accidents. Divers or underwater robots need to be sent to dive to disassemble and assemble the suction pump during installation. Generally speaking, the steel suction bucket pile is relatively heavy and requires a large floating crane for hoisting. The construction window period is short, and a large amount of materials, equipment, and labor are used in manufacturing, installation, and maintenance, resulting in high costs. Summary of the Utility Model

[0042] Please refer to Figures 1 to 5, the inventor provides a suction pile using retired wind turbine blades. The wind turbine blade includes a wind turbine blade root, a middle section of the wind turbine blade main beam, and a tail section of the wind turbine blade main beam. The cross-sectional dimension of the middle section of the wind turbine blade main beam is larger than that of the tail section of the wind turbine blade main beam. Before fabrication, the three parts of the retired wind turbine blade, namely the wind turbine blade root, the middle section of the wind turbine blade main beam, and the tail section of the wind turbine blade main beam, are cut.

[0043] The suction pile using retired wind turbine blades includes a pile foundation 10, a body rod 20, and a lifting sleeve 30.

[0044] The pile foundation 10 is the wind turbine blade root. A suction inlet 11 is provided at the bottom of the pile foundation 10. The suction inlet 11 can adopt the connection position between the wind turbine blade root and the wind turbine blade hub, where an opening is preset as the structure of the suction inlet 11. A material suction port 12 is provided on the pile foundation 10. The material suction port can adopt the connection position between the wind turbine blade root and the middle section of the wind turbine blade main beam, or an opening is drilled separately.

[0045] The body rod 20 is selected from the tail section of the wind turbine blade. One end of the body rod 20 is connected to the pile foundation 10. Specifically, the end of the body rod 20 can be fixed by welding or gluing an assembly plate to the wind turbine blade root, or the body rod 20 can be directly inserted into the inner side of the wind turbine blade root and fixed by gluing.

[0046] The lifting sleeve 30 is selected from the middle section of the wind turbine blade main beam. The lifting sleeve 30 is sleeved outside the body rod 20. An assembly part 31 is provided on the lifting sleeve 30 by means of welding, plugging, or bolt fixation.

[0047] According to the above structure, during the fabrication process of the suction pile using retired wind turbine blades, after the operator cuts the three parts of the retired wind turbine blade, namely the wind turbine blade root, the middle section of the wind turbine blade main beam, and the tail section of the wind turbine blade main beam, the wind turbine blade root is used as the pile foundation and connected to the tail section of the wind turbine blade main beam as the body rod, and the middle section of the wind turbine blade main beam as the lifting sleeve is sleeved outside the tail section of the wind turbine blade main beam. The bracket of the assembly part 31 is connected to the outside of the lifting sleeve 30.

[0048] During the installation of the suction pile using a retired wind turbine blade, the operator places the suction port 11 of the pile foundation 10 on the seabed to be assembled and fixed. Subsequently, the suction port 12 of the pile foundation 10 is connected through a pipeline, and the materials on the inner side of the pile foundation 10, that is, the inner side of the root of the wind turbine blade, are sucked. The materials such as water, sand, soil, and mud in the area corresponding to the suction port 11 are pumped away from the seabed and the inner side of the pile foundation 10 facing the suction port 11 through the pipeline, so that the pile foundation 10 extends into the seabed to complete the insertion. After completing the assembly of the suction pile using the retired wind turbine blade, the equipment or structure to be connected is assembled on the assembly part 31 of the lifting sleeve 30. When lifting is required, the lifting sleeve 30 of the equipment moves up and down on the body rod 20 to adapt to the height direction movement of the equipment or structure connected to the assembly part 31. For example, the lifting of the lifting sleeve is achieved by relying on a lifting device adapted by ropes and guide rails, or the buoyant module connected to the lifting sleeve is used to adapt to the water surface height. Or the lifting sleeve and the equipment connected to the lifting sleeve are pulled into the water through a winch structure to achieve the effect of avoiding wind and waves.

[0049] By adopting the root of the wind turbine blade, the middle section of the main beam of the wind turbine blade, and the tail section of the main beam of the wind turbine blade, the production of the suction pile is more convenient. The root of the wind turbine blade is used as the suction space of the suction pile, and the opening of the root of the wind turbine blade is used as the suction port. Only a small amount of hole opening and pipeline laying operations are required to achieve the penetration treatment of the pile foundation part of the suction pile, position and fix the suction pile, and connect the tail section of the main beam of the wind turbine blade to the root of the wind turbine blade to form the structure in the height direction of the upper part of the suction pile, and form a guiding structure that can move up and down along the height direction of the tail section of the main beam of the wind turbine blade. Compared with the lifting sleeve made of steel, the resistance encountered during the adjustment of the water surface height is lower, and the height adjustment is more flexible, which is convenient for the assembly of the lifting structure on the suction pile. The root of the wind turbine blade and the main beam structure are effectively utilized to form the assembly structure of the suction pile and the upper part of the suction pile, and the durable performance of the retired wind turbine blade is effectively utilized, such as excellent characteristics of ultraviolet resistance, weather resistance, corrosion resistance, fatigue resistance, high strength, and light weight. The construction and installation process is more convenient than that of the pile body structure made of steel structure or concrete structure.
