Single-pile fixed vertical shaft wind power generator with suction caisson

Abstract

The invention relates to a single-pile fixed vertical shaft wind power generator with a suction caisson in the technical field of marine fixed wind power generation, and the wind power generator comprises a vertical axis wind power generator, and a tower drum and the suction caisson which are arranged at the bottom of the machine in sequence and are provided with working platforms. The suction caisson is of an integral barrel-shaped structure which is formed by welding a steel sheet; a drainage short pipe and a flange are arranged on the top of the suction caisson. The single-pile fixed vertical shaft wind power generator with the suction caisson overcomes the defects of the prior art that the foundation installation fee of an offshore wind power generator is high, the installation cycle is long, the internal stress of the foundation of the offshore wind power generator is high, and the occupied area of a wind field is large, and has the advantages that the installation of the foundation of thewind power generator the whole system is quick, the installation cost is low, the internal stress of the foundation of the wind power generator is low, the occupied oceanic area of the wind field is small, and the like.

Description

technical field [0001] The invention relates to a device in the technical field of offshore fixed wind power generation, in particular to a single pile fixed vertical axis wind generator with a suction caisson. Background technique [0002] The current offshore wind power development is limited to shallow water areas and transition areas (water depth of about 0-50 meters), mainly using single pile fixed horizontal axis wind turbines, tripod (or jacket) type horizontal axis wind turbines. Different from traditional onshore wind turbines, the basic cost of offshore wind turbines (including installation costs) occupies a considerable proportion of the cost of the entire wind turbine system. Existing offshore wind turbines have two disadvantages: 1) The foundation installation cost of the wind turbine is high and the installation period is long; 2) The horizontal axis wind turbine exerts a large stress on the supporting foundation and occupies a large area of ​​the wind field. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a single-pile fixed vertical-axis wind motor with a suction caisson, which overcomes the high installation cost and long installation period of the foundation of the offshore wind motor in the prior art; The shortcomings of high stress and large area occupied by the wind field have the advantages of convenient installation of the wind turbine foundation of the entire system, low installation cost, low internal stress of the wind turbine foundation, and small sea area occupied by the wind field.
