Problems solved by technology

However, traditional wind turbines are bulky, noisy, and have high requirements for wind power. Generally, the requirement is not less than 5m / s, and it is difficult to install them in farmland and places other than coastal areas. These factors limit the further application of wind power generation

Embodiment 1

[0037] Such as Figure 1A , 1B , shown in 2 and 3, a kind of wind power generation tree system comprises the main shaft 8 that is fixed on the base 7 as the trunk of the power generation tree, and the main shaft 8 is provided with multi-layered fulcrums 9 as the branches of the power generation tree, and the fulcrum 9 is provided with a plurality of wind power generators as leaves of the power generation tree, the wind power generators include power generation blades, and the power generation blades include a blade body 4, and one or more concave notches 6 are symmetrically arranged on both sides of the blade body 4 .

Embodiment 2

[0039] On the basis of Example 1, such as image 3 , 5 , 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, and the upper and lower sides of the sub-blades 41 are respectively provided with Parallel rectifying grids 42, one or more sub-blades 41 are symmetrically provided with concave notches 6 in the center of both sides, and the rectifying grids 42 on the upper and lower sides of the sub-blades 41 are oppositely provided with air guide strips 43 for guiding wind force. An S-shaped air guide channel is formed between the rectifying grids 42 on the upper and lower sides.

Embodiment 3

[0041] On the basis of Example 1, such as figure 2 , 5 , 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, and the upper and lower sides of the sub-blades 41 are respectively provided with Parallel rectifying grids 42, the two sides of the sub-blades 41 at the bottom of the blade body 4 are symmetrically provided with concave notches 6, and the rectifying grids 42 on the upper and lower sides of the sub-blades 41 are relatively provided with air guide strips 43 for guiding wind force, An S-shaped air guide channel is formed between adjacent rectifying grids 42 on the upper and lower sides.

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.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a wind power generation tree system. Background technique [0002] Energy is the basis and important condition for the progress and development of human society and economy. For a long time, the energy system based on fossil fuels such as coal, oil, and natural gas has promoted the development of human society. However, the above-mentioned energy sources are non-renewable energy sources. Long-term development has caused energy exhaustion, which seriously restricts the further development of human beings. Wind power generation is a green, renewable and clean energy. It is a device that converts the kinetic energy of the wind into mechanical kinetic energy, and then converts the mechanical energy into electrical kinetic energy. However, traditional wind turbines are large in size, loud in noise, and have high requirements for wind power, generally not less than 5m / ...
