In order to overcome the problems existing in the prior art, the utility model provides a wind power generation device, the technical problem that solve includes at least how to avoid adopting the bracing piece that is high again heavy to and how to make things convenient for the maintenance.
In order to solve the above problems, the wind power generation device of the present invention comprises a plurality of mounting supports and a generator rotor, wherein the generator rotor is in a ring shape, and the generator rotor is supported at the top of the mounting supports and can rotate around the center of a circle of the generator rotor; the top surface of the generator rotor is fixedly provided with a plurality of blades, and the plurality of blades can drive the generator rotor to rotate under the driving of wind power.
The plurality of blades are uniformly arranged at equal intervals along the circumference of the generator rotor.
The plurality of mounting brackets are uniformly arranged at equal intervals along the circumferential direction of the generator rotor below the generator rotor.
In a preferred embodiment, the top of the mounting support is provided with a positioning wheel, and the outer peripheral wall of the positioning wheel is in slidable contact with the inner peripheral wall of the generator rotor.
Further preferably, a supporting wheel is arranged on the side surface of the mounting support, and the generator rotor is supported on the top of the supporting wheel.
Preferably, an electric storage device is further arranged on the side surface of the mounting support, and electric energy generated by rotation of the generator rotor is stored in the electric storage device.

The invention realizes the following beneficial effects:
compared with the prior art, wind power generation set, can cancel traditional high heavy bracing piece again, adopt a plurality of evenly arranged's along the circumference of generator rotor erection support to support the weight of fan blade, reduced because of the high requirement in the aspect of bracing piece length and hardness leads to the cost-rise. Meanwhile, the mounting support can be mounted at the top of a high-rise building, and wind power can still be fully utilized. And because the height of the mounting support is far lower than that of the support rod of the traditional wind power generation device, workers can easily contact all structural components of the wind power generation device, including the structure of the fan blade, when standing on the top of a high-rise building, and therefore the maintenance can be conveniently carried out.

Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1 to 3, the wind power generation device of the present invention includes a plurality of mounting supports 1 and a generator rotor 2, wherein the generator rotor is circular, and the generator rotor is supported on the top of the mounting supports and can rotate around the center of a circle of the generator rotor; the top surface of the generator rotor is fixedly provided with a plurality of blades, and the plurality of blades can drive the generator rotor to rotate under the driving of wind power.
The plurality of blades are uniformly arranged at equal intervals along the circumference of the generator rotor.
The mounting brackets 1 are arranged equidistantly and uniformly along the circumference of the generator rotor below the generator rotor.
In a preferred embodiment, the top of the mounting support is provided with a positioning wheel 6, and the outer peripheral wall of the positioning wheel is in slidable contact with the inner peripheral wall of the generator rotor.
Further preferably, the side of the mounting support is provided with a support wheel 5, and the generator rotor is supported on the top of the support wheel.
Preferably, the side surface of the mounting support is also provided with an electric storage device 3, and electric energy generated by the rotation of the generator rotor is stored in the electric storage device.
As shown in fig. 3, the blade includes a streamlined protrusion portion 41 and a flat portion 42.
Wind power generation set when using, can be with a plurality of erection support 1 direct mount at high-rise building's top to can cancel traditional high heavy bracing piece again, thereby reduction in production cost. Because the center part of the generator rotor is hollow, the space of the center part can be fully utilized, and the space utilization of the building is not influenced. The weight of the generator rotor and the fan blades and the shearing force generated by wind power are shared by a plurality of mounting supports (including the supporting wheel 5), and the weight born by a single mounting support is far less than the weight born by a traditional supporting rod. When the generator rotor rotates, the positioning wheel 6 exerts radial force which is dispersed outwards along the radial direction of the generator rotor on the generator rotor from the inner peripheral wall of the generator rotor, and the generator rotor is prevented from falling. The prior art of the generator belongs to the field of generator technology, and the cutting of magnetic lines to generate electricity when the rotor of the generator rotates is not described herein.
As shown in fig. 2 and 3, the blade includes a streamlined protrusion portion 41 and a flat portion 42. When the air flow is blown to the blade in the direction of arrow W in fig. 2, the wind generates a pressure difference between the streamlined protrusion 41 and the flat portion 42, thereby generating a driving force F on the blade, which in turn drives the generator rotor to rotate in the direction of arc-shaped arrow R.
When the air flow is blown against the blades in the direction of arrow W in fig. 3, the wind exerts a driving force F directly on the flat portion 42, and the generator rotor is driven to rotate by the blades.
It is fully understood by those skilled in the art that the plurality of vanes can be adjusted in angle by the control means in the prior art to adapt to air flow in different directions, for example, the angle of the vanes can be adjusted by the stepping motor in the prior art, which is not described herein in detail.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
