Description

Draught fan foundation jacket Technical Field The utility model belongs to the technical field of fan foundation jackets, and particularly relates to a fan foundation jacket. Background At present, the wind turbine foundation for offshore wind power generation mainly comprises a single pile foundation, a jacket foundation, a high pile cap foundation, a suction barrel foundation, a single pile composite barrel foundation, a floating foundation and the like. The single pile foundation and the jacket foundation are used as main components, the high pile cap foundation is used in parts of the fowling and Shanghai sea areas, other sites are used in a small amount, the suction barrel foundation is used in the fowling and Changle wind power plant whole plant, the rest wind power plant is basically in a model machine form, the single pile composite barrel foundation is also mainly in a model machine form, the floating foundation is still in a model machine research and development stage, and the floating foundation is still difficult to commercialize at present. The fan foundation jacket needs to be used for fixing the offshore wind turbine when the offshore wind turbine is installed, but the existing fan foundation jacket is impacted by seawater for a long time when the jacket is used, so that the problem that the jacket is easy to shake and the problem that the whole pressure relief buffer protection can not be realized is solved, and the whole stability of the fan foundation jacket is affected.
