These wind power generators 30 are arranged in two layers, each layer having a plurality of wind power generators 30, and are uniformly arranged around the center pillar 20. The placement positions of the wind power generators 30 can be adjusted as required, and the wind power generators are uniformly distributed around the center pillar 20 as much as possible, so that energy absorption can be performed to the greatest extent.
The wind power generator 30 includes a generator assembly 31 and a wind energy absorber 32.

These connecting rods 323 are also distributed in an annular array. In this embodiment, the turntable 321 is a turntable in a shape of a regular five-pointed star, and has five connection angles 3214 in a triangle shape, an included angle between each angle is 36 degrees, and the blades 322 are five, and in fact, the turntable 321 may also be in a shape of a triangle star, a seven-pointed star, or the like, that is, the number of the connection angles 3214 and the blades 322 may be arbitrarily set.
The blade 322 has a spherical shape of a circular arc, i.e., a shape obtained by cutting a sphere with two planes passing through the center of a circle. The angle between the two end surfaces of the blade 322 is 110-160 degrees, preferably 144 degrees in this embodiment, as shown in fig. 5 b. Because the two opposite sides of the connecting angle 3214 of the five-pointed star turntable 321 are 144 degrees, as shown in fig. 3, the top force can be effectively reduced, and the energy absorbing effect of the blade 322 is improved.

The radian of each blade is 144 degrees, and the included angle between the blade and the opposite side of the five-pointed star is 144 degrees (such as < a >' aE), so that the connecting rod is parallel to the next blade surface, and the air flow passing through the connecting rod (such as Aa rod) from the front surface is free from obstruction. Except for reasonable layout of the blades of 144 degrees, other angles are set, and all the angles are intersected at corresponding extension lines to form virtual closure, so that tourbillon is generated, and obstacle airflow is prevented from being directly communicated.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
