Description

Technical Field

[0001] The present invention belongs to the field of energy technology, and in particular relates to a wind-solar integrated system with high power generation. Background Art

[0002] As fossil fuels continue to be consumed, human society is not only facing a reduction in fuel, but also serious environmental pollution and ecosystem damage. Therefore, the development and utilization of renewable, pollution-free clean energy is the focus of attention of all countries in the energy field. Among them, solar power generation is a relatively popular renewable clean energy. Solar energy's photothermal conversion and photoelectric conversion are used in every corner of human life.

[0003] Wind energy is generated by air velocity, which is converted into electrical energy to supply power to the grid. In areas with abundant wind energy, a large number of windmills are usually installed to supply power to the grid through the rotation of windmills. In areas with abundant wind energy, solar energy is also abundant, and solar photovoltaic panels are also installed on the ground to supply power to the grid using solar energy. The wind-solar hybrid power generation system uses the complementarity of wind and solar energy resources to generate electricity. It is a power generation system with high cost performance and promising application prospects. At present, there are two main structures of common wind-solar hybrid power generation systems. Among them, the first is to install the wind turbine and solar photovoltaic components independently on the ground; the second is to simply combine the wind turbine and solar photovoltaic components together, that is, to support the solar photovoltaic components on the main bracket of the wind turbine through a bracket. Compared with the first power generation system structure, the structure of this power generation system reduces the footprint. However, both structures are simple combinations, and both require the use of wind turbine blades and solar photovoltaic components together, and they are not organically combined. Summary of the invention

[0004] In order to solve the defect in the prior art that wind power generation and photovoltaic power generation are not organically combined, the present invention provides a wind-solar integrated system with high power generation.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a high-power generation wind-solar integrated system, comprising

[0006] A support body, installed on the ground;

[0007] A generator, mounted on the support;

[0008] A rotating shaft connected to a generator, and used to drive the generator to rotate and generate electricity;

[0009] A blade, mounted on the rotating shaft, and used to drive the rotating shaft to rotate;

[0010] The blade comprises a photovoltaic module, the cells in the photovoltaic module are double-sided power generation cells, and the surface of the rotating shaft has a reflective structure.

[0011] As an embodiment, it further comprises a bracket, and the blades are mounted on the rotating shaft through the bracket.

[0012] In one embodiment, a support frame is provided on the outer edge of the photovoltaic assembly, and the support frame is connected to the bracket.

[0013] In one embodiment, the reflective structure comprises a reflective device disposed on the surface of the rotating shaft, wherein the reflective device is disposed between two adjacent blades and is used to reflect light to the blades.

[0014] In another embodiment, the reflecting device includes at least a first reflecting surface and a second reflecting surface, the first reflecting surface and the second reflecting surface are connected on the side away from the rotating axis, and the first reflecting surface and the second reflecting surface are away from each other on the side close to the rotating axis and are respectively connected to the rotating axis.

[0015] In one embodiment, the first reflecting surface and the second reflecting surface are planes.

[0016] In another embodiment, the first reflecting surface and the second reflecting surface are arcuate surfaces, and the arcuate surfaces are concave toward the rotating shaft along the axial direction of the rotating shaft.

[0017] Specifically, the number of the blades is 4, and the 4 blades are evenly distributed along the circumference of the rotating shaft. The number of the reflective devices is 4, and each of them is located between two adjacent blades.

[0018] Preferably, the cell in the photovoltaic module is a half-cell cell.

[0019] Beneficial effects:

[0020] The present invention directly replaces traditional wind power blades with photovoltaic modules. The photovoltaic modules not only serve as components for generating electricity using light sources, but also serve as wind power blades, thereby organically combining wind power generation and photovoltaic power generation, increasing power generation and saving materials.

[0021] In addition, the photovoltaic module of the present invention uses double-sided power generation cells, and a reflective structure is arranged on the rotating shaft, which can use reflected light to generate electricity, further improving the power generation.

[0027] The present invention will be further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative changes belong to the protection scope of the present invention.

[0028] like Figures 1 to 4 As shown, a high-power generation wind and solar integrated system includes

[0029] A support body 1 is installed on the ground;

[0030] A generator 2, mounted on the support 1;

[0031] The rotating shaft 3 is connected to the generator 2 and is used to drive the generator 2 to rotate and generate electricity;

[0032] The blade 4 is mounted on the rotating shaft 3 and is used to drive the rotating shaft 3 to rotate;

[0033] The blade 4 includes a photovoltaic module, in which the cells are double-sided power generation cells, and the surface of the rotating shaft 3 has a reflective structure 5.

[0034] As an embodiment, a bracket 6 is further included, and the blade 4 is mounted on the rotating shaft 3 through the bracket 6 .

[0035] In one embodiment, a support frame is provided at the outer edge of the photovoltaic module, and the support frame is connected to the bracket 6. The photovoltaic module can be designed as a front glass layer, an encapsulation layer, a bifacial power generation cell, an encapsulation layer and a back glass layer, and a support frame is provided at the edge of the photovoltaic module. The support frame can include a crossbeam located at the back of the photovoltaic module and a frame around the edges. The use of the support frame can effectively improve the strength of the photovoltaic module as a blade 4, and at the same time facilitates the connection with the bracket 6. The bracket 6 can be fixedly connected to the frame or to the crossbeam.

[0036] In one embodiment, the reflective structure 5 includes a reflective device disposed on the surface of the rotating shaft 3, and the reflective device is disposed between two adjacent blades 4 to reflect light to the blades 4. Figure 2 As shown, the reflective device can be a reflective coating 53 provided on the surface of the rotating shaft 3, but the present invention is not limited thereto, and other structural reflective devices will be described in other embodiments. When the back of the blade 4 faces the sun during the rotation process, the back can be directly used to generate electricity, and when the front faces the sunlight, the back can still use the reflected light of the reflective device to generate electricity, thereby improving the light utilization rate.

[0037] In another embodiment, Figure 3 and 4 As shown, the reflecting device at least includes a first reflecting surface 51 and a second reflecting surface 52, the first reflecting surface 51 and the second reflecting surface 52 are connected on the side away from the rotating shaft 3, and the first reflecting surface 51 and the second reflecting surface 52 are away from each other on the side close to the rotating shaft 3, and are respectively connected to the rotating shaft 3. That is, the reflecting device forms a toothed structure on the surface of the rotating shaft 3, changes the light reflection path, and makes as much reflected light as possible be reflected to the back of the photovoltaic module, further improving the light utilization rate. At the same time, the toothed structure also increases the contact area with the wind, and can also play the role of the blade 4, improving the wind utilization rate. That is to say, the reflecting device improves both the light utilization rate and the wind utilization rate. The reflecting surface can be a mirror reflection or diffuse reflection structure.

[0038] In one embodiment, Figure 3 As shown, the first reflecting surface 51 and the second reflecting surface 52 are planes. The reflecting surface with a plane structure is more conducive to processing, molding and installation.

[0039] In another embodiment, Figure 4 As shown, the first reflecting surface 51 and the second reflecting surface 52 are arcuate surfaces, and the arcuate surfaces are concave toward the rotating shaft 3 along the axial direction of the rotating shaft 3. The arcuate surfaces are more conducive to reflecting light to the photovoltaic module, further improving the utilization rate of light.

[0040] Specifically, the number of the blades 4 is 4, and the 4 blades 4 are evenly distributed along the circumference of the rotating shaft 3. The number of the reflecting devices is 4, and they are respectively located between two adjacent blades 4. The number of blades 4 can be selected according to actual conditions, and the present invention is not limited thereto. Of course, the number of reflecting devices can be more than the number of blades 4 to increase the contact area with the wind and improve the utilization rate of the wind.

[0041] Preferably, the cell in the photovoltaic module is a half-cell cell. In the photovoltaic module, multiple half-cell cells in a group can be connected in series to form a group of battery strings, and then multiple groups of battery strings are connected in parallel to form a battery group, and then the battery group is packaged to obtain a photovoltaic module. The photovoltaic module formed by the structure of first connecting half-cell cells in series and then in parallel can reduce the impact of shading, and at the same time, the current is halved to reduce the hot spot temperature and increase the power generation.

[0042] The present invention is particularly suitable for a vertical axis wind turbine 2 , in which the photovoltaic modules are used as blades 4 of the vertical axis wind turbine 2 , and a corresponding reflective structure 5 is arranged on the rotating shaft 3 .

[0043] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
