Embodiment 1

[0037] refer to Figure 1 to Figure 6 As shown, this embodiment discloses that the present invention provides a prestressed assembled concrete frame support structure for wind turbines. A steel tower 9 to be fixed is arranged on the top of the supporting structure, and a wind turbine 10 is installed on the top of the steel tower 9 .

[0038] Preferably, the support structure includes: a bottom support unit, a middle support unit, a top support unit and several prestressed steel strands 8 .

[0039] Wherein, the bottom support unit is a rectangular frame structure; the middle support unit is arranged on the upper end of the bottom support unit, and the middle support unit is composed of overlapping standard structural units; the top support unit is arranged on the middle support The top of the unit; each prestressed steel strand runs through the holes longitudinally arranged in the bottom support unit, middle support unit and top support unit respectively, and completes the lo...

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...
