Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing:

[0028] Such as Figure 1-2 As shown, the vertical axis wind turbine with layered dislocation combined blades includes an intermediate rotary shaft 3, a support platform 4 and at least two blade devices with the same structure, the intermediate rotary shaft is fixed on the support platform, and the blade devices include multiple Each blade is connected with the middle rotary shaft, and the positions of the blades in the upper and lower adjacent two-layer blade devices are arranged in a staggered manner.

[0029] Such as figure 1 As shown, the vertical axis wind turbine with layered and dislocated combined blades includes two blade devices with the same structure, which are the upper blade 1 and the lower blade 2 .

[0030] The blades are all connected to the intermediate rotary shaft 3 through a truss. The blades are H-shaped blades. The intermediate rotary shaft 3 connect...

Abstract

The invention discloses a vertical axis wind turbine provided with layered and staggered combined blades. The vertical axis wind turbine comprises a middle revolving shaft, a support platform and at least two blades of blade devices of the same structures, wherein the middle revolving shaft is fixed on the support platform; the blade devices comprise a plurality of blades; each blade is connected with the middle revolving shaft; the blades in the upper and lower adjacent layers of blade devices are arranged in a staggered way. By adopting a layered and blade-staggered structure, starting is facilitated, and the starting wind speed is lowered.

Description

technical field [0001] The invention relates to a vertical axis wind turbine with layered dislocation combined blades. Background technique [0002] At present, domestic and foreign research on large-scale wind turbines is mostly concentrated on horizontal-axis wind turbines. The design theory of horizontal-axis wind turbines has matured, while the technical research and development level of vertical-axis wind turbines is relatively lagging behind. Mature, it is generally believed that the wind energy utilization rate of the vertical axis wind turbine is lower than that of the horizontal axis, but the vertical axis wind turbine has special advantages compared with the horizontal axis: no need for wind-facing devices and can adapt to the wind from all directions; the blades can bear the wind The pressure is small, and it can be made into light blades; the generator can be placed at a low altitude, and the weight of the tower can be reduced. Research on the starting technolog...
