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
[0014] 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 driver 3 , a lower support 4 , a lower support attachment 5 , a transmission 6 , a fixed base 7 and guide vanes 8 . The main rotating shaft 1 is rigidly connected with the upper support 2 and the lower support 4, and two or more lower support accessories 5 are evenly distributed around the lower support 4, and the cross-section of the lower support accessories 5 is designed to be streamlined; The driving machine 3 is installed between the upper supporting part 2 and the lower supporting part 4, and is evenly distributed around the main rotating shaft 1, and the lower part of the rotating shaft of the driving machine 3 passes through the lower supporting part 4. Between the upper support 2 and the lower support 4, on the inner side of the driving machine 3 close to the main rotating shaft 1, guide vanes 8 with the same number as the...

The invention discloses a vertical axis wind turbine, and belongs to the field of wind power generation. The problem that an existing damping vertical axis wind turbine is low in wind energy utilization rate, and a lifting type vertical axis wind turbine is difficultly subject to self starting is solved. The vertical axis wind turbine is the vertical axis wind turbine including drive machines, lowguide blades are arranged between an upper supporting part and a lower supporting part, located on the inner sides, close to a main rotating shaft, of the drive machines, and are evenly arranged, thenumber of the flow guide blades is the same with that of the drive machines, a center wind turbine is formed by the flow guide blades, takes the axis of the main rotating shaft as the center and hasthe flow guide effect, and the novel vertical axis wind turbine composed of the center wind turbine and a drive unit is formed. According to the vertical axis wind turbine, the principle that the drive machines can achieve autoroatation and revolution, and the principle of wind resistance and flow guide of the flow guide blades of the center wind turbine are used for enabling wind energy utilization rate of the drive machines to be further improved, and through the drive moment of the center wind turbine to the main rotating shaft, the wind energy utilization rate of the whole turbine is greatly improved.
Description
technical field [0001] The invention belongs to the field of wind power generation. Specifically, it relates to a vertical axis wind turbine. Background technique [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. Contents of the invention [0003] The present invention is a vertical-axis wind turbine, which is installed between the upper support and the lower support of a vertical-axis wind turbine that includes a driving machine, the driving machine is close to the inner side of the main rotating shaft, and the number of driving machines is uniformly distributed and installed with the same number of driving machi...
