Problems solved by technology

The lightning protection device of the wind power generator in the prior art should be installed on the blade, which is limited by the rotating structure of the blade, and the lightning protection effect is not good. Overvoltage causes the automatic control and communication components of the fan to be burned, the generator and other valuable components to be broken down, and the electrical equipment to be damaged. It is also a serious problem that threatens the safe operation and economic operation of wind turbines.

Embodiment Construction

[0037] Such as figure 1 , 2 As shown in and 3, the multi-stage impeller wind generator provided by the present invention includes a tower 1 with a triangular section and a turbine wind generator.

[0038] The tower 1 is a triangular tower with a triangular cross section. Compared with the existing rectangular cross-section tower, this triangular tower is not easy to be overturned by wind because its multiple lateral windward faces are lateral faces. In the longitudinal direction of the tower 1, several layers of tower support frames 10 are arranged from top to bottom, and perforations 11 are arranged on the tower support frames of each layer.

[0039] The turbine wind generator includes a vertical shaft 2 and several wind impellers 3, the vertical shaft 2 passes through the perforation 11 on the tower support frame 10 of each layer, and is rotatably fixed to the tower support frame 10 of each layer through the bearing 21 One wind impeller 3 is respectively arranged in the s...

Abstract

The invention provides a multi-stage impeller wind-driven generator which comprises a tower post and a wind-driven generator, wherein the tower post is vertically provided with multiple layers of tower post bearing supports, each layer of tower post bearing support is provided with a perforation, the wind-driven generator comprises a vertical shaft and multiple wind-driven impellers, the verticalshaft penetrates through each layer of tower post bearing support and is rotatably fixed with each layer of tower post bearing support, the wind-driven impellers are respectively arranged in the spaces between the multiple layers of tower post bearing supports and are rotatably fixed on the vertical shaft, and the lower end of the vertical shaft is connected with a generator set. The multi-stage impeller wind-driven generator can be operated under the condition of a breeze with a wind speed of 2m / s to generate electricity, can also safely generate electricity under the condition of a strong wind, and has the advantages of reasonable structure, less easily worn parts, small maintenance capacity, convenient installation and maintenance and long service life up to 20-50 years.

Description

[0001] The applicant applied for a utility model patent with respect to the present invention. technical field [0002] The invention belongs to the technical field of wind power generation, and relates to wind power generation equipment, in particular to a multi-stage impeller wind power generator. Background technique [0003] At present, in order to obtain greater power, wind power generators have become a development trend of large-scale. Existing wind power generators are divided into two types: horizontal axis generators and vertical axis generators. In order to obtain a larger air collection volume, the length of the impeller blades of these two generators is also made larger and larger. Generating sets with a weight of tens of tons and hundreds of tons are installed on the upper end of a support more than 100 meters high. Installation, commissioning and repair at high altitude must cooperate with large-scale lifting machinery for high-altitude operations. Due to the...
