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, while a large part of the wind blows from the bottom of the fan and is wasted
[0005] When the inventor implemented the above-mentioned patent, he encountered many problems that had to be solved. In order to solve these problems, he also changed and designed many other schemes. In the process, he also filed patent applications for two schemes wherein, but All are not ideal, through thinking and experiment more than half a year, consulted many expert friends, especially introduced the concept of sensor and controller, because subject span is bigger, be difficult to understand, paid a lot of hard work; The present invention mainly Applied to large-scale wind turbines, in such a field, even a small technical change will cause a series of problems, such as the impact on the entire wind farm, the impact on the supporting generator, the impact on the load, Therefore, what seems to be a small improvement, in actual work, is the result of a lot of creative work.

Embodiment 1

[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 section A-B is convex upward, the section B-C is concave upward, and the highest part of the wind gathering surface is higher than the bottom part of the wind sweeping surface of the blade , so that the wind gathered in section A-B can most effectively reach the most effective part of the fan blade; The bottommost part of the surface, if it is a downwind wind turbine, is placed horizontally behind and below the wind-sweeping surface of the wind wheel. The wind-gathering surface is defined in the present invention as a convex-concave surface. The advantage is that the wind gathering position and wind gathering direction are accurate and the effect is good.

Embodiment 2

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

[0101] Figure 5 It is a schematic diagram of the front view of the structural principle of the present invention. The wind gathering surface is a smooth convex surface or a half-barrel surface. At the rear and lower part of the wind-sweeping surface of the wheel, the highest part of the convex surface is higher than the bottommost part of the wind-sweeping surface of the blade. The wind-gathering surface is defined as a convex-convex surface in the present invention.

[0103] Image 6 It is an overall schematic diagram of a structure principle of the present invention.

Embodiment 3

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

[0106] Figure 7 It is a schematic diagram of the front view of the structure principle of the present invention. The wind gathering surface is a streamlined curved surface. The D-E section is a slow rising section, and the E-F section is a steep descending section. machine, then horizontally placed on the back and lower side of the wind rotor sweeping surface, the highest position of the convex surface is higher than the bottom position of the blade sweeping surface, and the wind gathering surface is defined as: gentle and steep surface in the present invention. The advantage is that the wind gathering position is accurate.
