Technical Field

The invention belongs to the technical field of wind driven generators, and particularly relates to vertical axis wind driven generators.

Background

With the development of society, non-renewable fossil energy is gradually exhausted, the concern of human to the living environment is gradually intensified, clean renewable energy is inevitably selected by the human society, wind power generation is the earliest clean energy recognized by human beings, common vertical axis wind power generators are divided into a lift type and a resistance type, the lift type has the defects that the starting rotating moment is small, the starting is not easy, correspondingly, the wind energy utilization efficiency is low, the resistance type has the defects that the rotating speed is low, the low wind speed rotating moment is large, the wind energy utilization efficiency curve is straight, and the efficiency is low.

Disclosure of Invention

The invention aims to provide vertical axis wind driven generators, which simultaneously combine a lift force type wind driven generator and a resistance type wind driven generator into a body, have the functions of the two, integrate the advantages of the two into a body and have high wind energy utilization efficiency.

In order to achieve the purpose, the invention adopts the technical scheme that:

vertical axis aerogenerator, including the main shaft, the main shaft bottom is equipped with motors, along the main shaft from last a plurality of supporting disks of evenly setting down, through splined connection between supporting disk and the main shaft, the supporting disk is ring shape, and the supporting disk evenly is equipped with three construction bolt along its circumference, all is equipped with the interior blade of level settings on every construction bolt, and every interior blade opening direction is the same.

step, the inner blade includes two end plates of controlling parallel arrangement and the arc of connecting two end plates, the end plate is oval arc, and the interfacial shape of arc is the same with the end plate, and arcs are constituteed to arc and two end plates and are held the chamber, hold the projection width that the chamber opening part top is less than the projection width of bottom.

, the number of the supporting disks is three.

, all be equipped with construction bolts on the end plate of supporting disk side is kept away from to three inner leaf, and three inner leaf tip is equipped with vertical direction's outer leaf, and outer leaf passes through construction bolts and three inner leaf fixed connection, the height of outer leaf is the same with the height that the leaf is apart from bottom inner leaf in the top.

And , the opening direction of the outer blade is the same as that of the inner blade, and the shape and the structure of the outer blade are the same as those of the inner blade.

The vertical axis wind driven generator has the advantages that the vertical axis wind driven generator is provided with the inner blades in the horizontal direction and the outer blades in the vertical direction, each blade is enclosed by the end plates at the two ends and the arc-shaped plate in the middle to form pockets, the contact area between the blades of the wind driven generator and wind is increased, the rotating speed is high, the wind energy utilization efficiency is high, when the wind direction is changed, the arc-shaped curve at the rear part of each blade has a lift force type function under the driving of wind power, the starting rotating speed is high, the wind energy utilization rate is high, the vertical axis wind driven generator has the lift force type function and a resistance type function, the function types can be switched along with the change of the wind direction, and the wind energy is utilized to the maximum extent.
