Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention is a wind power tower based on a cable-stayed cable-steel girder self-balancing system, and relates to the technical field of wind power generation. The system includes a fan (1), a tower (2), a stay cable (3), a connecting beam (4), a cable vibration damper (5), a mass damper (6), and a foundation (7). The stay cable (3) is made of ultra-high-strength steel with a tensile strength greater than 1500MPa and prestressed at the construction site, and the two ends are respectively anchored on the tower (2) and the connecting beam (4); the connecting The beam (4) is connected to the bottom of the tower (2), and the end is connected to the foundation (7); a fan (1) is arranged on the top of the tower (2), and a mass damper (6) is arranged; The stay cable vibration damper (5) is installed on the stay cable (3).

Abstract

The invention discloses a wind-power tower barrel based on a stay cable-steel beam self-balance system, and relates to the technical field of wind power generation. The system comprises a fan, the tower barrel, a stay cable, a linking beam, a stay cable vibration-attenuation damper, a mass damper and a base, wherein the two ends of the stay cable are separately anchored on the tower barrel and thelinking beam; the linking beam is connected with the tower barrel, and the end part of the linking beam is connected with the base; one fan is arranged on the top of the tower barrel, and the mass dampers is arranged on the tower barrel; and the stay cable vibration-attenuation damper is mounted on the stay cable. According to the tower barrel, the stay cable is arranged to reduce bending momentof a tower body, so that the tower barrel main bears vertical axial pressure, and therefore, strength of the material can be sufficiently utilized, and the section dimension of the tower barrel is reduced. The tower barrel is simple in structure, is good in vertical and integral stability, and is a brand-new wind-power tower barrel structural form.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] With the rapid development of modern industry, human's demand for energy has increased sharply. At the same time, energy security and environmental protection issues have also aroused people's concern and anxiety. People must seek and develop other new energy sources that can replace traditional fossil fuels. Wind energy is a non-polluting, renewable and clean energy. Compared with other energy sources currently available, wind power has the advantages of short construction period, low cost, high reliability, simple operation and maintenance, and small actual land occupation. my country's wind energy reserves are very rich, so the wind power industry has broad prospects for development and utilization. [0003] The wind turbine tower is the main load-bearing structure of the wind turbine. It supports the wind turbine at the top and provides the requir...
