Embodiment Construction
[0019] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.
[0020] The most critical idea of the present invention is that the fixed main shaft is covered with a movable main shaft, and a disc-shaped reinforcing plate is fixed on the movable main shaft, and multiple groups of blade shaft groups are rotatably connected between each two reinforcing plates, and the blade shaft groups evenly surround the Around the active main shaft; the blade shaft group includes impeller blades and impeller blade shafts. The impeller blades are rectangular, and the impeller blades are fixed on the impeller blade shafts. The impeller blade shafts are rotatably connected to the reinforcing plate. The shaft group rotates around the fixed main shaft, and the impeller blades also rotate around the axis of the impeller blades. The wind energy u...

The invention provides a vertical axis wind power generation structure with high wind energy utilization rate and strong wind resistance, which includes a wind wheel, the wind wheel includes a fixed main shaft, a movable main shaft, a reinforcing plate and a blade shaft group, and the movable main shaft is sleeved on the fixed main shaft In addition, the reinforcing plate is disc-shaped, the movable main shaft passes through the center of the reinforcing plate, the reinforcing plate is fixed on the movable main shaft, and there are more than two reinforcing plates, and every two reinforcing plates There are several sets of blade shaft groups rotatably connected between them. The blade shaft groups evenly surround the movable main shaft. The blade shaft groups include impeller blades and impeller blade shafts, and the impeller blades are fixed in the impeller shaft. The impeller blade shaft is rotatably connected with the reinforcing plate. The beneficial effect of the present invention is that: driven by the wind, not only the blade shaft group rotates around the fixed main shaft, but also the impeller blades rotate around the impeller blade shaft, the utilization rate of wind energy is high, the structure is simple, and strong wind can be resisted.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a vertical axis wind power generation structure. Background technique [0002] The wind is produced because the sun heats the air on the surface of the earth, the air expands and becomes lighter due to heat and rises up. After the hot air rises, the low-temperature inner air flows in from the surrounding sideways, thus forming the flow of air, which is the wind. Wind power generation is generated by the wind pressure when the air flows. With the aerodynamic effect of the air (including lift and drag), the blades of the wind turbine are driven to rotate, which in turn drives the generator to rotate and convert it into electrical energy. Although there are many kinds of wind turbines, they can be summarized into two categories: ①Horizontal axis wind turbines, the rotation axis of the wind rotor is parallel to the wind direction; ②Vertical axis wind turbines, the rotation axis o...
