Problems solved by technology

Due to the huge size of this kind of wind turbine, the rotating shaft is generally relatively high. In order to strengthen its stability, the cable is pulled from the top of the rotating shaft to the bottom surface. Although the rotating shaft has been reinforced, the occupied area is relatively large, which is not conducive to the effective use of land.
In addition, the power transmission chain in the process of wind power generation is too long, and the power loss in the transmission process is very large, which is not conducive to the effective use of energy

Embodiment 1

[0037] Such as Figures 1 to 3As shown, a vertical wind power generator includes a tower column 1 , a generator and two blades 9 . The tower column 1 is hollow, and a power generation device is arranged on the tower column 1 . The power generating device is composed of the first lower flange 2a and the first upper flange 2b, the first bearing seat 3, the first bearing 4, the first generator 5, and the generator center column 20 arranged on the tower column 1. , The second bearing 7, the second bearing seat 8, the second lower flange 11a and the second upper flange 11b. The first lower flange 2a is fixed to the tower column 1, the first upper flange 2b is located on the first lower flange 2a and is fixedly connected with the first lower flange 2a, the first The bearing seat 3 is fixed on the first upper flange 2b, the first bearing 4 is composed of a first outer ring 41, a first steel ball set 42 and a first inner ring 43, and the first inner ring 43 is fixed on the second O...

Embodiment 2

[0042] Such as Figures 4 to 6 As shown, a vertical wind power generator includes a tower 1, a generator and two blades 9; the tower 1 is hollow, and a power generation device is arranged on the tower 1. The power generating device is composed of the first lower flange 2a and the first upper flange 2b, the first bearing seat 3, the first bearing 4, the first generator 5, and the generator center column 20 arranged on the tower column 1. , the second bearing 7, the second bearing seat 8, the second lower flange 11a and the second upper flange 11b; the first lower flange 2a is fixed to the tower column 1, and the first upper The flange 2b is located on the first lower flange 2a and is fixedly connected with the first lower flange 2a, the first bearing seat 3 is fixed on the first upper flange 2b, and the first bearing 4 is formed by The first outer ring 41, the first steel ball group 42 and the first inner ring 43 are formed. The first inner ring 43 is fixed on the first bearin...

Embodiment 3

[0046] Such as Figures 9 to 10As shown, the difference from Embodiment 2 is that two power generating devices are arranged on the tower column 11, and the power generating device located on the lower floor includes a first lower flange 2a, a first upper flange 2b, a first bearing Seat 3, first bearing 4, first generator 5, first exciter 21, generator central column 20, second bearing 7, second bearing seat 8, second lower flange 11a and second upper flange and a second generator 13 including a second inner stator 131 , a second outer rotor 132 and a second exciter 22 is provided below the second bearing 7 . The power generation device on the upper floor is identical in structure to the power generation device on the lower floor. The power generation principle of the two power generation devices is the same as that of the power generation device described in Embodiment 2, and will not be described in detail here.

Abstract

The invention provides a vertical wind power generator, comprising a pylon, an electric generator and more than two blades, wherein the pylon is hollow, and mor than one generating set is fixed on the pylon; the generating set is composed of a first flange and a second flange fixed on the pylon, a first bearing block, a first bearing, a first electric generator, a first exciter, an electric generator center post, a second bearing, a second bearing block, a second lower flange and a second upper flange; a crane is fixed at the top of the pylon and an elevator is fixed in the pylon. The vertical wind power generator of the invention has advantages of simple and safe structure, small accommodation area, low cost and high utilization ratio of wind energy, and the structure is convenient to maintenance and detection.

Description

technical field [0001] The invention relates to a wind power generator, especially a vertical wind power generator. Background technique [0002] Now, the resources of non-renewable energy are less and less, and even some energy has been exhausted. Therefore, such energy as wave energy, combustible ice, coal bed methane, and microorganisms will become new energy widely used by human beings, and wind energy, a regenerative type Energy has been used in many regions and equipment, and its technology has gradually matured. Modern wind turbines mainly include horizontal axis wind turbines and vertical axis wind turbines, which are different from similar products of the horizontal axis type. In vertical axis wind turbines, the rotating shaft is installed on the vertical axis, perpendicular to the ground, and vertical axis wind power The machine is always in line with the wind direction, so there is no need to adjust when the wind direction changes. Among them, the Darrieus turbi...
