Example Embodiment

[0036] Example 1

[0037] Such as Figure 1A , 1B , 2, 3, a wind power generation tree system, including a main shaft 8 fixed on the base 7 as the trunk of the power generation tree, the main shaft 8 is provided with multiple fulcrums 9 as branches of the power generation tree. There are a plurality of wind power generators as leaves of power generation trees, the wind power generator includes power generation blades, the power generation blades include a blade body 4, and the blade body 4 is symmetrically provided with one or more concave notches 6 on both sides. .

Example Embodiment

[0038] Example 2

[0039] On the basis of Example 1, such as image 3 , 5 As shown in 6, the cross section of the blade body 4 is S-shaped, and the blade body 4 includes a plurality of sub-blades 41 connected sequentially from top to bottom. The upper and lower sides of the sub-blade 41 are respectively provided with a horizontal direction Parallel rectifying grid 42, one or more sub-blades 41 are provided with concave notches 6 symmetrically on both sides of the sub-blade 41. The rectifying grids 42 on the upper and lower sides of the sub-blade 41 are oppositely provided with air guide bars 43 for guiding wind. An S-shaped air guiding channel is formed between the upper and lower sides of the rectifying grid 42.

Example Embodiment

[0040] Example 3

[0041] On the basis of Example 1, such as figure 2 , 5 As shown in 6, the cross section of the blade body 4 is S-shaped, and the blade body 4 includes a plurality of sub-blades 41 connected sequentially from top to bottom. The upper and lower sides of the sub-blade 41 are respectively provided with a horizontal direction The parallel rectifying grids 42 are provided with concave notches 6 symmetrically on both sides of the sub-blade 41 located at the bottom of the blade body 4, and the rectifying grids 42 on the upper and lower sides of the sub-blade 41 are oppositely provided with air guide strips 43 for guiding wind. An S-shaped air guiding channel is formed between the adjacent upper and lower sides of the rectifying grid 42.

Abstract

The invention belongs to the field of wind power generation and particularly relates to a wind power generation tree system. A main shaft fixed to a base and serving as a power generation tree trunk is included, and is provided with a plurality of layers of branch shafts serving as power generation tree branches; the branch shafts are provided with a plurality of wind driven generators serving aspower generation tree leaves; each wind driven generator comprises power generation blades; each power generation blade comprises a blade body; and one or more U-shaped notches are formed in the two sides of each blade body in a central symmetry manner. The wind power generation tree system has the beneficial effects that the wind power generation tree system is provided, due to the fact that theplurality of micro wind driven generators are arranged according to a tree-shaped structure and each wind driven generator is small in body shape, the blades can rotate under the breeze condition, andpower generation is achieved.
