Description

Novel large-diameter single pile for offshore wind power

Technical Field

The invention relates to the field of offshore wind power equipment, in particular to a novel large-diameter single pile for offshore wind power.

Background

An offshore wind power plant is a novel power plant which generates power by using offshore wind resources. Under the condition that the situation of petroleum resources is increasingly severe, all countries project eyes to sea areas with huge wind power resources, the real development of the wind power industry starts from the petroleum crisis in 1973, and the demonstration wind power field is built in the 80 th century in 20 th, so that the wind power industry becomes a new power source of a power grid, and the wind power development keeps the fastest world energy position in the following 20 years. The annual average growth rate of the global wind power accumulated installed capacity is close to 30.00 percent in the first decade of the 21 st century, and wind power technology is mature day by day.

The first reason that wind power generation enters the sight of people is that the wind power generation is environment-friendly, the power of the wind power generation is derived from air flow on the surface of the earth, in a certain sense, the final source of the wind power generation is also solar energy which is renewable energy, the problems existing in the existing fossil energy can be perfectly solved in a theoretical level, however, in the actual construction process of a wind power plant, numerous secondary problems are caused, the most important reason is noise pollution generated by running machinery in the working process of a wind generating set, the living environment around the wind power plant is seriously influenced, meanwhile, the construction of the wind power plant needs to occupy wide open land, and the wind power plant is beyond the limit of the current earth-occupied society.

The offshore wind power station perfectly solves a plurality of problems of the land wind power station, a wide offshore area provides a wide construction space for the offshore wind power station, meanwhile, the tidal wind which keeps day and night also provides a sufficient power source for the wind generating set, noise generated by the wind generating set during working has small influence on human activities due to the fact that the wind generating set is far away from the coast and the residential area, but compared with the terrestrial environment, the marine environment is complex, the corrosion degree of the sea water is far higher than that of the atmosphere due to a large amount of salt dissolved in the sea water, the marine current corrosion caused by a large amount of marine organisms is accompanied, and the service life of a single pile manufactured by the wind generating set is seriously influenced.
