Abstract

Provided is a high-power vertical-shaft multiple wind wheel group combined type wind power generation tower wheel. A horizontal blade and a vertical blade are arranged above a main wind wheel, a turntable is arranged under the main wind wheel, a main wind wheel power generating chamber is arranged under the turntable, a tower base is arranged under the main wind wheel power generating chamber, and an outer wall of the main wind wheel power generating chamber is provided with an auxiliary wind wheel. The auxiliary wind wheel is composed of trusses and a vertical blade, wherein the trusses are symmetrically arranged on the outer wall of the main wind wheel power generating chamber, and the vertical blade, a small wind wheel and a small wind wheel power generating chamber are arranged between the trusses. The high-power vertical-shaft multiple wind wheel group combined type wind power generation tower wheel is provided with the vertical blades with combined lifting force and resistance and the turbo type horizontal blade capturing upflow in the wind wheels, and by means of design and installation of two types of blades, poor self-starting problem of a vertical shaft fan can be effectively solved, and wind power coefficients of the fan can be improved remarkably. The small wind wheel can directly absorb wind energy in negative sides of the main wind wheel and the auxiliary wind wheel in windward and can absorb wind energy formed in wake flow disturbed areas of the back sides of the windward sides of the main wind wheel and the auxiliary wind wheel.

Description

technical field

[0001] The invention relates to a vertical axis wind power generator, in particular to a high-power vertical axis multi-wind wheel group combined wind power generation tower wheel. Background technique

[0002] In the field of wind power generation, the existing lift-type wind turbines have poor self-starting performance, and the system is prone to vibration, while the drag-type wind turbines have a relatively low speed. The structures of these two types of wind turbines have low wind energy utilization coefficient and stability. problem of poor sex. These defects have seriously hindered the popularization and upscaling of vertical axis wind turbines. In recent years, the field of wind power has been trying to combine the lift and drag of the vertical axis wind power generation technology model, and has achieved some gratifying results, but it has not been able to make a major breakthrough in the safety and stability of large-scale wind turbines. No one has...

Embodiment Construction

[0031] Such as Figure 1-Figure 5 As shown, the high-power vertical axis multi-wind wheel group combined wind power generation tower wheel, pouring the cement tower base 1 of the fan with a total height of 6-10 meters, the tower base 1 is divided into two modes according to the height and function of the fan:

[0032] (1) The power generation capacity is 1 MWh, the total height is 40-60 meters, the tower base 1 is integrated layout mode: the height is 15 meters, the diameter is 22 meters, and the inside is the generator room. The top of the tower base and the top of the machine room are where the rolling bearings are arranged. The cement outer wall of the machine room is where the auxiliary wind wheel guide rail is arranged.

[0033] (2) The power generation capacity is 2 MWh, the total height is 60-80 meters, and the diameter of tower foundation 1 is arranged in two sections: the upper section is 45 meters high and the diameter is 38-68 meters. The hollow is the generator r...
