Problems solved by technology

"Its shortcoming is: in the middle of practical application, the wind gathering surface described in this embodiment has single directionality, does not rotate with the wind direction and rotates, therefore, its shortcoming is that if the wind is not from low When the direction of the surface is blown to the direction of the high surface, but when it is blown from the directions of two sides, then this invention has no effect, and it cannot achieve the purpose of improving the efficiency of the fan or wind power generator. In fact, it is almost useless Furthermore, even when the wind is blowing from the direction of the low surface to the direction of the high surface, since the wind gathering surface is completely located under the fan blade, although the wind passing through the fan blade below can be gathered, the wind gathering efficiency Low, only a small part of the wind can reach the effective part of the fan and blow to the tip of the fan blade,

Example Embodiment

[0096] Example one:

[0097] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, figure 1 It is a front view schematic diagram of a structural principle of the present invention. The wind gathering surface is the connection of two smooth curved surfaces. The AB section is convex upwards, and the BC section is concave upwards. The highest part of the wind gathering surface is higher than the bottom of the blade sweeping surface. , So that the wind gathered in the AB section can reach the most effective part of the fan blades most effectively; the wind gathering surface is placed across the front and bottom of the sweeping surface of the wind turbine, and the highest part of the convex surface is higher than the sweeping wind of the blades. If the bottom of the surface is a downwind wind turbine, it is placed horizontally behind the sweeping surface of the wind wheel. The wind gathering surface is defined in the present invention as a convex-concave surface. The advantage...

Example Embodiment

[0099] Embodiment two:

[0100] Similarly, such as Figure 5 , figure 2 , image 3 , Image 6 As shown,

[0101] Figure 5 It is a front view schematic diagram of a structural principle of the present invention. The wind gathering surface is a smooth convex surface or a half-bucket-shaped surface. The convex surface is upward and is placed horizontally in front of and below the sweeping surface of the wind turbine. If it is a downwind wind turbine, it is placed horizontally on the wind The highest part of the convex surface is higher than the lowest position of the blade sweep surface at the rear and lower part of the wind sweep surface of the wheel. The wind gathering surface is defined as a convex convex surface in the present invention.

Example Embodiment

[0104] Embodiment three:

[0105] Similarly, such as Figure 7 , figure 2 , image 3 , Figure 8 As shown,

[0106] Figure 7 It is a front view schematic diagram of a structural principle of the present invention. The wind gathering surface is a streamlined curved surface, the DE section is a slow ascending section, and the EF section is a steep descending section. The convex surface is upward, and it is placed across the front and bottom of the wind turbine sweeping cover. The wind turbine is placed horizontally behind and below the sweeping surface of the wind wheel, and the highest part of the convex surface is higher than the lowest position of the sweeping surface of the blade. In the present invention, the wind gathering surface is defined as a slowly steep surface. The advantage is that the wind gathering position is accurate.
