Problems solved by technology

[0003] In the prior art, a variety of low-power vertical-axis wind turbines for household use have been disclosed, but there are some problems: adjust the windward angle of the sail blades with a fixed mechanism so that the resistance is the largest when the wind is downwind, and the resistance is the smallest when the wind is headed
Some mechanisms for adjusting the resistance of sail blades are too simple, and the ratio of forward and reverse wind resistance is not large, so they cannot efficiently absorb wind energy
Rotary bearings are all mechanical bearings, which are less efficient and often break down
At the same time, the organization is relatively fragile, and it is difficult to meet the needs of family industrial workshops

Embodiment 1

[0040] As shown in Figures 1-1, 1-2, 1-3, and 1-4, the low-power vertical axis wind power generator described in the present invention is constituted as follows: the upper and lower ends of the central column 1 are fixedly supported by the upper sail blades Disc 3 and lower sail blade support disc 4, there are 4 sail blades 2 installed between the two sail blade support discs, each sail blade 2 is rotatably mounted on the upper and lower sails through two upper and lower sail blade couplings 5 Between the leaf supporting discs 3 and 4. In this embodiment, the lower end of each sail blade 2 is connected to a blade windward angle driving mechanism 8 through a blade coupling 5; the central column 1 has two rotation support points, one is an anchor 6 at the upper end, and the other is at the upper end. The lower end is the main bearing 9. They allow the central column 1 and all components assembled on the central column 1 to rotate around the central main axis. The windward angl...

Embodiment 2

[0049]Another implementation method of the central rotation mechanism of the low-power vertical-axis wind turbine according to the present invention is shown in Fig. 4-1. Referring to Fig. 4-2, the anchor 6 is composed of a central shaft 20, a bearing assembly 21, and an anchoring disk 22, wherein a central shaft 20 is set in the center of the anchoring disk 22, and a stop 201 is provided at the lower end of the central shaft 20, through which the The central shaft 20 passes through the central column 1 and is fixed on the lower chassis rotation central shaft 904 of the main bearing 9; the upper part of the central shaft 20 is movably installed with the central column 1 through the bearing assembly 21, and the anchor plate 22 passes through the anchor ring 15 , steel cable 13 anchors. Therefore, the connection between the central shaft 20 and the lower chassis 901 of the main bearing thrust bearing is fixed and does not rotate during the operation of the wind power generator. ...

Abstract

The invention discloses a low-power vertical wind generator fixed with upper vane and lower vane supporting discs at the upper and lower ends of a center column, respectively, installing plural vanes between the two supporting discs through vane shaft coupling, where the lower end of each vane is connected with a vane windward angle drive mechanism through the vane shaft coupling, the upper end of the center column is connected with an anchor and the lower end of the center column is connected through a main bearing to a base, the main bearing is connected with a generator equipped with reducer through a power transmission mechanism provided with sensor; a wind vane is arranged above the anchor, and the sensor is connected with the windward angle drive mechanism through main controller and the whole is anchored with cable through the anchor, and the main bearing is of a compound pull bearing structure. And it effectively prolongs service life and has strong practicality.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a low-power vertical-axis wind power generator with composite thrust bearing structure, which can automatically adjust the windward angle of sail blades. Background technique [0002] According to the ratification of the Kyoto Protocol by various countries, the world will rapidly expand the demand for clean energy. Wind power is one of the most accessible clean energy for human beings, so it is facing great opportunities for development. The family is the basic unit of social energy demand, so the cleanliness of household energy is of great significance. A lot of domestic wind generators have been disclosed in the known technology, most of which are horizontal axis low-power wind generators. There are also some vertical axis wind turbines. In the case of low power (below 1000W), the two have their own strengths relative to each other, and there is no absolute advantage at all...
