The surface of the convex structure is arc-shaped. One side of the convex bar close to the air shaft has an outward inclined side. The surface of the side side should be parallel to the bottom surface of the wind guide strip. The side and bottom surface of the wind guide bar form a 45 degree angle with the surface of the blade. There are many air grooves parallel to the blade on the surface of the air shaft.
The reinforcing rib increases the strength of the connection between the blade and the air shaft, and improves the safety, but the unreasonable structure will increase the wind resistance of the wind blade. The inclined and continuously arranged reinforcing rib can guide the direction of the air flow, avoid the air shaft as much as possible, and improve the air flow speed, so as to increase the air volume.
