Truss structure of wind turbine generator set

Abstract

The invention relates to a truss structure of a wind turbine generator set. The truss structure of the wind turbine generator set comprises steel-pipe piles (1), inserting sections (2), jacket pile legs (3), supporting steel pipes (4), a tower platform (5) and inclined struts (6), wherein the steel-pipe piles (1) extend into a supporting layer below the seabed, the inserting sections (2) are partly inserted into the upper ends of the steel-pipe piles (1), the jacket pile legs (3) are welded to the upper ends of the inserting sections (2), the supporting steel pipes (4) are welded between the two jacket pile legs (3), the tower platform (5) is arranged above the jacket pile legs (3) and the supporting steel pipes (4), and the inclined struts (6) are welded above the tower platform (5) and connected with a tower (7) arranged above the tower platform (5). Piling is carried out in advance, and the truss structure enables a steel structure and the steel-pipe piles to be integrated by inserting the inserting sections into the steel-pipe piles and then pouring binding materials, offshore workload of workers is reduced, offshore working time is shortened, influences of weather and climate changes on construction are less, and construction cost is reduced greatly.

Description

【Technical field】 [0001] The invention relates to a structure of a truss type wind power generating set. 【Background technique】 [0002] Wind power is the fastest growing new energy in the world. Offshore wind power represents the highest level of wind power technology today. It requires high reliability, easy installation, and easy maintenance of equipment. The market is huge and the risk is extremely high. Attention is setting off an investment boom. At present, more than 100 countries and regions have begun to develop wind power, and the main markets are concentrated in Europe, Asia and North America. [0003] my country's offshore wind resource reserves are abundant, and the basic conditions for large-scale development have been met. According to the preliminary results of the China Meteorological Administration's detailed investigation of wind energy resources, it is measured that the installed capacity of wind power in my country's offshore areas within the water dept...

Problems solved by technology

[0004] Due to the particularity of offshore construction, under the current technical conditions, the foundation of offshore wind turbines is usually constructed with concrete caps. Since offshore construction is easily affected by weather and climate changes, the construction volume is large, the cycle is long, and the cost is high, the staff hope that offshore Most of the construction work of the wind turbine foundation structure is completed in the factory or on the shore, minimizing the time for offshore construction operations
