Problems solved by technology

Because this kind of wind power generator is relatively huge, 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, it occupies a relatively large area, 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. The blades are driven by the wind, the blades drive the vertical shaft, the shaft drives the transmission gear inside the gearbox, and the gearbox drives the generator rotor. If there is power transmission, there will be losses. In this way, The loss of power in the transmission process is relatively large, which is not conducive to the effective use of energy
Furthermore, the power generation device includes multiple sets of components such as gearboxes, generators, and drive shafts to complete power generation. The structure is relatively complicated. Once the power generation device fails, it will be difficult to overhaul and repair.

Description

technical field [0001] The invention relates to a wind power generator, especially a vertical wind power generator. Background technique [0002] There are two main designs of modern wind turbines: horizontal-axis wind turbines and vertical-axis wind turbines. In vertical-axis wind turbines, the rotor shaft is mounted on a vertical axis, perpendicular to the ground. Unlike its horizontal-axis counterpart, a vertical-axis wind turbine stays in line with the wind, so it doesn't need to adjust when it changes; it's typically supported by guy cables rather than towers, so the rotor is lower. Among them, the Darrieus turbine is a type of vertical wind power generator, which includes a vertical shaft, a top rotor center at the top of the shaft, blades, a bottom rotor center at the bottom of the shaft, a gearbox connected to the shaft, and a Generator composition. The upper end of the blade is connected to the center of the top rotor, and the lower end of the blade is connected t...
