Problems solved by technology
[0002] At present, most of the common wind turbines are horizontal axis wind turbines. Although its technology is quite mature, there are still some shortcomings; vertical axis wind turbines can make up for some shortcomings of horizontal axis wind turbines, but the wind energy utilization rate of drag vertical axis wind turbines Low, and some lift-type vertical axis wind turbines are difficult to self-start

Embodiment Construction
[0012] Such as figure 1 As shown, the vertical axis wind turbine of the present invention includes a main rotating shaft 1, an upper support 2, a driving machine 3, a lower support 4, a lower support attachment 5, a transmission device 6 and a fixed base 7. The main rotating shaft 1 is rigidly connected to the upper support 2 and the lower support 4. The upper support 2 is designed to be streamlined in cross section, and the lower support 4 is disc-shaped; two or more lower supports are installed around the lower support 4 The accessories 5 are evenly distributed around the main rotating shaft 1, and the cross-section of the lower support accessory 5 is also designed to be streamlined; the driver 3 is installed between the upper support 2 and the lower support 4, and is evenly distributed on the main rotating shaft Around 1, the lower part of the rotating shaft of the driver 3 passes through the lower support 4. Such as figure 2 As shown, the transmission device 6 includes a ...

The invention discloses a vertical axis wind turbine, and belongs to the field of wind power generation. The vertical axis wind turbine solves the problems that an existing resistance type vertical axis wind turbine is lower in wind energy utilization rate, and some lift type vertical axis wind turbines are hard to start. Upper supporting pieces and lower supporting pieces are horizontally mounted on a vertical shaft called as a main rotating shaft and are in rigid connection with the vertical shaft; the upper supporting pieces are evenly distributed in the radial direction with the main rotating shaft as the center, and the number of the upper supporting pieces is two or more; the lower supporting pieces are in disc shapes, and transmission devices are arranged on the lower portions of the lower supporting pieces; two or more resistance type vertical axis wind turbines called as driving machines are evenly distributed on the position, between the upper supporting pieces and the lower supporting pieces, around the main rotating shaft and drive the transmission devices. Under a certain wind effect, the driving machines can rotate around axes of the driving machines and can drive the transmission devices, the upper supporting pieces and the lower supporting pieces to jointly rotate around the axis of the main rotating shaft to do revolution, the aim of driving the main rotating shaft to rotate is achieved, and the wind turbines begin to rotate.
Description
Technical field [0001] The invention belongs to the field of wind power generation. Specifically relates to a vertical axis wind turbine. Background technique [0002] At present, most common wind turbines are horizontal-axis wind turbines. Although their technology is quite mature, they still have shortcomings; vertical-axis wind turbines can make up for some shortcomings of horizontal-axis wind turbines, but resistance-type vertical-axis wind turbines have wind energy utilization Low, some lift-type vertical axis wind turbines are difficult to start automatically. Summary of the invention [0003] The invention is a vertical axis wind turbine. An upper support and a lower support are installed horizontally on a vertical axis called the main rotating shaft to be rigidly connected to it. The upper support is uniformly distributed in the radial direction with the main rotating shaft as the center, and the number is two or more, and The cross-section is designed to be streamlined...
