Embodiment 1

[0045] One of the implementations of a semi-floating vibration-absorbing horizontal-axis wind power generating set of the present invention, such as Figure 1 to Figure 4As shown, it includes a tower 12 and a blade drive assembly located on the tower 12. The blade drive assembly includes a wind wheel group and a vertical vertical axis rotation system. The wind wheel group includes two or more lift-type The blades and two or more fan blade brackets 5 corresponding to the vertical vertical axis rotation system, the number of groups of lift type blades can be three or five groups, which are equally distributed around the axis of the generator 6; the vertical vertical axis rotation The system includes a generator 6 and a column 1, one end of the column 1 is connected to the stator of the generator 6, one end of the fan blade bracket 5 is fixedly connected to the lift type blade, and the other end of the fan blade bracket 5 is connected to the other end of the column 1 It is connec...

Embodiment 2

[0049] One of the embodiments of a semi-floating vibration-absorbing vertical-axis wind power generating set of the present invention, such as Figure 1 to Figure 4 As shown, the main technical solutions of this embodiment are basically the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the elastic component also includes a spring connection part, the spring connection part is installed on the mounting base 7, the second spring 10 is arranged below the spring connection part, and a buffer tightening is provided above the spring connection part. The third spring 8 in the loosening gap of the bolt 11 , the bolt 11 passes through the third spring 8 , the spring connection part and the second spring 10 in sequence. The setting of the third spring 8 is mainly to tighten the loosening gap of the bolt 11, and further strengthe...

Embodiment 3

[0052] One of the embodiments of a semi-floating vibration-absorbing vertical-axis wind power generating set of the present invention, such as Figure 1 to Figure 4 As shown, the main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, and the features not explained in this embodiment are explained in Embodiment 1 or Embodiment 2, and will not be repeated here. . The difference between this embodiment and embodiment 1 or embodiment 2 is that there are multiple sets of elastic components, and multiple sets of elastic components are evenly distributed and connected to the mounting base 7 . The optimal number of groups for this elastic component is three groups. It can not only satisfy the balance of the wind power generating set, but also save cost and simplify the manufacturing process.

Abstract

The invention relates to a semi-floating shock-absorption type vertical-axis wind turbine generator set. The semi-floating shock-absorption type vertical-axis wind turbine generator set comprises a tower frame and a fan blade driving assembly arranged on the tower frame; the fan blade driving assembly comprises a wind wheel set and a vertical-axis rotation system; the wind wheel set comprises lift type blades and a fan blade support; the vertical-axis rotation system comprises a power generator and an upright column; one end part of the upright column is connected with a stator of the power generator; one end part of the fan blade support is fixedly connected with the lift type blades; the other end part of the fan blade support is connected with the other end part of the upright column; a semi-floating type spring shock-absorption device which is used for reducing the vibration when the fan blade driving assembly operates is arranged; the power generator is arranged on the tower frame through the semi-floating type spring shock-absorption device. The semi-floating type spring shock-absorption device is connected with the fan blade driving assembly and the tower frame, so that the semi-floating shock-absorption type vertical-axis wind turbine generator set is capable of operating in a balanced manner and normally generating power when operating at a high speed in strong wind, and is good in strong wind resistance and stable and safe to operate; the wind turbine generator set is simple in structure, low in cost, relatively high in stability and relatively high in safety.

Description

technical field [0001] The invention relates to the technical field of vertical-axis wind power generators, in particular to a semi-floating vibration-absorbing vertical-axis wind power generator set. Background technique [0002] At present, traditional energy sources are becoming exhausted, and the development of new energy sources is imperative. Wind power generation has a history of more than 150 years. After analyzing the atmospheric circulation model, scientists have found that the wind energy contained in the convective air masses in the lower atmosphere is very huge. , is one of the inexhaustible and inexhaustible renewable energy available to human beings. Therefore, under the situation that human beings are facing the energy crisis that is gradually intensified, the research and development of wind power generation has more and more important and far-reaching practical significance. In some developed countries, such as the United States, the Netherlands, Denmark, ...
