Example Embodiment

[0036] Example 1:

[0037] refer to Figure 1 to 6 , The present embodiment discloses an embodiment of the present invention provides a wind turbine assembly of prestressed concrete framework support structure. The support structure is provided to be fixed to the top of steel towers 9, 9 to the top of the steel tower 10 is mounted with a wind turbine.

[0038] Preferably, the support structure comprising: a bottom support unit, the middle support unit, the support unit and a plurality of top prestressing strands 8.

[0039] Wherein said underlying support means is a rectangular frame structure; the middle support unit is provided on an upper end of the underlying support unit and the middle support unit by a number of standard structural units constituting the superimposed; a supporting unit disposed on the middle top support the top unit; prestressing strands are each disposed in the longitudinal direction through the bottom of the support unit, the support unit pore middle and to...

Abstract

The invention discloses a prestress assembly type concrete frame supporting structure of a wind turbine generator set, the top end of a supporting structure is provided with a steel tower to be fixed, the top end of the steel tower is provided with the wind turbine generator set, and the supporting structure comprises a bottom-layer supporting unit, a middle-layer supporting unit, a top-layer supporting unit and a plurality of prestressed steel strands. The bottom-layer supporting unit is of a rectangular frame body structure; the middle-layer supporting unit is arranged at the upper end of the bottom-layer supporting unit, and the middle-layer supporting unit is formed by overlapping a plurality of standard structure units; the top-layer supporting unit is arranged at the top end of the middle-layer supporting unit; and the prestressed steel strands penetrate through hole bodies longitudinally formed in the bottom-layer supporting unit, the middle-layer supporting unit and the top-layer supporting unit correspondingly, and longitudinal connection and fixation of the bottom-layer supporting unit, the middle-layer supporting unit and the top-layer supporting unit are completed. By means of the supporting structure, the problem that node bolts and inclined struts in a traditional lattice type tower are unfavorable in stress is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a prestressed assembled concrete frame support structure of a wind turbine. Background technique [0002] The development of new renewable energy has become a major strategic demand for the development of countries all over the world. Wind power is a clean, high-efficiency, renewable new type of energy, which can solve the problem of energy consumption. It has developed rapidly in recent years. The height of construction is getting higher and higher, so that the total weight of wind power towers continues to increase, which requires the supporting structure to have better bearing capacity. [0003] Compared with the bending mode of the single member of the traditional tower, the axial force bearing mode of the corner member of the lattice tower fully utilizes the high bearing capacity and large lateral stiffness of the concrete or steel tube concrete st...
