Problems solved by technology
This structure is relatively simple. Although the large wind blade has a large torque, but the speed is low, the speed of the input shaft when the wind blade drives the generator through the main shaft is low, which affects the working efficiency of the generator.
And the volume of the low-speed motor is too large, so it is difficult to use it on a high-power model, and the use has great limitations

The invention discloses a vertical shaft type wind power generation device. The vertical shaft type wind power generation device comprises a vertical shaft which rotates vertically, wherein a frame mounting rack is fixedly arranged on the top of the vertical shaft; a first fan blade frame, a second fan blade frame, a third fan blade frame and a fourth fan blade frame which are symmetric relative to the vertical shaft are fixedly arranged on a side surface of the frame mounting rack; a first fan blade is hinged to the end, which is away from the frame mounting rack, of the first fan blade frame; a second fan blade is hinged to the end, which is away from the frame mounting rack, of the second fan blade frame; a third fan blade is hinged to the end, which is away from the frame mounting rack, of the third fan blade frame; and a fourth fan blade is hinged to the end, which is away from the frame mounting rack, of the fourth fan blade frame. The vertical shaft type wind power generation device has the advantages that the structural design is reasonable, the structure is reliable, wind energy and water energy can be used for generating power, energy is saved, the environment is protected, the vertical shaft type wind power generation device is convenient to manufacture and mount, the green development concept is met, and the popularization prospect is good.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a vertical shaft wind power generator. Background technique [0002] Most of the current small and medium-sized wind turbines adopt a direct-drive structure, which is characterized in that the blade flange is directly connected to the engine shaft, and the speed of the wind blade is consistent with the speed of the motor. This structure is relatively simple, because although the large fan blade has a large torque, its rotating speed is low, so that the input shaft rotating speed of the fan blade driving the generator through the main shaft is relatively low, which affects the working efficiency of the generator. Moreover, the volume of the low-speed motor is too large, so it is difficult to be used on a high-power model, and the use has great limitations. How to provide a vertical-axis wind power generation device suitable for wave power generation and wind power g...
