Polyhedral ice-resistant unit suitable for single-column three-pile type offshore wind power foundation

Abstract

The invention belongs to the technical field of ice-resistant units for offshore wind power foundations, and discloses a polyhedral ice-resistant unit suitable for a single-column three-pile type offshore wind power foundation. The wind power foundation is provided with a set of ice-resistant unit with a polyhedron structure, and the ice-resistant unit comprises a polyhedral inverted ice-resistant cone, connecting parts arranged between the foundation and the ice-resistant cone, an upper plane and a lower plane of the cone and conical surface steel plate reinforcing devices. After the ice-resistant cone is adopted, extrusion damage is converted into bending damage in the interaction of sea ice and the structure, so that the extreme static ice force and the structural ice-induced vibration borne by the offshore wind power foundation are effectively reduced, and the safe operation of the wind power structure is guaranteed; meanwhile, the polygonal cone adopts a plane steel plate splicing structure, so that the production-manufacturing and installing are convenient, the manufacturing cost is lower compared with a traditional circular-cone-shaped cone, and the economic performance of the offshore wind power structure is considered while the ice-resistant function is achieved; and the connecting reinforcing devices are arranged between every two adjacent contact planes of the polyhedral ice-resisting cone, so that the stability of the ice-resistant cone structure is enhanced.

Description

technical field [0001] The invention belongs to the technical field of anti-icing devices for offshore wind power foundations, and relates to a polyhedral anti-icing device suitable for single-column three-pile offshore wind power foundations. Background technique [0002] As the energy crisis continues to emerge, the use of offshore wind energy for power generation has become a trend, and many cold regions have also opened a new chapter in the development of offshore wind farms. At present, the factors restricting the development of offshore wind power include three aspects: low technical level, low electricity price, and high construction cost. Among them, the fundamental reason affecting the development of wind power is high cost and poor economy. Since the offshore wind farm is an unmanned platform, and the wind farm is composed of several wind turbines, the safety and economy of a single wind turbine are crucial to the development of the entire wind farm. Since the cos...

Problems solved by technology

[0004] At present, the design of anti-icing devices for wind power foundations in cold regions is immature. Most of the anti-icing designs come from offshore oil platforms, and the structural forms are combined with forward and backward cone structures. This type of structure is less economical. The multi-faceted anti-icing device not only satisfies the anti-icing function but also takes structural economy into account. This anti-icing device is an effective measure to promote the development of offshore wind power in cold regions
