All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Example one

Referring to fig. 2 to 4, in the first embodiment, a vertical shaft wind power generator 1 is provided, which includes an external rotor motor device 10, blades 11 spaced along a circumferential direction on an outer wall surface of the external rotor motor device 10; a guide plate 12 provided along the outer periphery of the blade 11;

the number of the guide plates 12 is the same as that of the blades 11, and each guide plate 12 is arranged corresponding to the corresponding blade 11 one by one; the number of the blades and the number of the guide plates are respectively N, and the N is 3, 4, 5, 6, 8, 9, 10 and 12 according to the local wind conditions and the cost, and the number of the blades and the guide plates is not necessarily equal.

The cross section of the blade 11 is a concave curved surface (the cross section of the blade is a curved surface, and it is a concave surface of the curved surface that is pushed by wind power), the guide plates 12 are distributed at the periphery of the blade with the outer rotor motor device as a center at an inclined angle, the guide plates 12 are linear substrates, and the inclined included angle between any two adjacent guide plates is delta; delta is 360/N; in the embodiment of fig. 2, since the number of the baffles 12 is 12 (N is 12), the included angle of inclination between any two adjacent baffles is 30 degrees.

It should be noted that, in the technical solution of the present application, the above-mentioned vertical shaft wind power generator has designed the guide plate and the corresponding number of blades, and the cross section of the blade is an inwards concave curved surface, and naturally it can form a curved plate structure with an inwards concave inner surface and an outwards convex outer surface, and the curved plate structure can produce a better wind pressure difference effect (the concave surface is in the rotating process, the wind pressure is guided in by the guide plate, and the convex surface is in the rotating process, the wind pressure is blocked by the guide plate).

The blade with the specific concave surface design can realize corresponding wind pressure difference, however, the guide plate can increase the wind guiding and wind gathering effect on one hand, so that the wind pressure difference is increased adaptively, and on the other hand, the guide plate can also increase the wind guiding effect, so that the rotation efficiency of the rotor is further enhanced, and the power generation efficiency of the generator is also indirectly enhanced.

Specifically, the number of the blades is N, and the blades and the guide plate are both circle centers (or the centers of the three shafts coincide) with the outer rotor motor device. The cross section of the blade is concave and convex, wherein the concave surface catches wind and the convex surface exhausts wind. The concave surface faces the wind, the wind pressure is large, and the wind pressure is set to be P1; the convex surface exhausts air, the wind pressure is small, and the wind pressure is set as P2. The P1-P2 are positive, pressure difference is generated, and the pressure difference generates power at the concave-convex structure of the blades at two sides to drive the outer rotor motor device to rotate. The guide plate is used for further increasing the wind pressure difference. When the convex surface turns to the vertical wind direction, P2 is the largest. At this time, the air deflector is arranged right in front of the convex surface, the direction is vertical to the wind direction, the wind pressure is completely blocked, and P2 is close to 0. After the guide plates are arranged according to the number of the blades, the wind pressure of the concave surface is increased by the guide plates on one side of the concave surface, so that the P1 is increased by more than 2.7 times. According to the calculation, the driving wind pressure of the outer rotor motor device is changed from P1-P2>0 to 2.7P1, and the wind power generation effect is remarkably improved.

Of course, researchers design and demand that the air deflectors are distributed on the peripheries of the blades with the outer rotor motor device as a central inclination angle, meanwhile, the air deflectors are linear substrates, the difference between the inclination angles of any two adjacent air deflectors is a fixed value, and the air deflectors can be guaranteed to realize the 'undifferentiated air guiding effect' through the design of the matching effect and the position relation between the air deflectors and the blades, that is, referring to fig. 3 and fig. 4, it can be seen that the air deflectors can be designed to ensure that air guiding is not affected by the wind direction, and have a relatively ideal wind direction guiding effect (i.e., the wind direction guiding direction is definite), so that frequent vibration and damage of the blades due to the fact that the rotating wind direction of the outer rotor is not definite because of instantaneous wind direction change or continuous wind direction are avoided, and finally, through the definite wind direction guiding effect, the rotating efficiency of the rotor (i.e., the outer rotor) in the vertical shaft wind power generator is guaranteed, finally, the wind power generation effect is obviously improved. In addition, the inclination angle of the guide plate is beneficial to realizing the functions of automatically guiding wind and guiding the direction of the guided wind.

Meanwhile, the outer rotor motor device has a gearless structure, and the maintenance cost is reduced.
