[0030] The following will describe in detail the implementation mode of the present invention with reference to the drawings.

[0031] Embodiment 1

[0032] As Figure 1 shown, an energy device combining photovoltaic and wind power includes a wind power generation unit. At least one group of photovoltaic power generation units 2 is arranged on the circumferential side of the support tower 1 of the wind power generation unit. The photovoltaic power generation unit 2 includes a semi-circular mounting frame 21 and a solar tracking controller 22 arranged in the annular chute 11 on the support tower 1. A plurality of photovoltaic modules 23 are arranged on the semi-circular mounting frame 21 through an angle adjustment mechanism 24. Both the semi-circular mounting frame 21 and the angle adjustment mechanism 24 are electrically connected to the solar tracking controller 22.

[0033] As Figure 2 - Figure 4 shown, driving columns 211 are provided at both ends of the semi-circular mounting bracket 21. An installation channel 212 is provided at one end of the driving column 211. The installation channel 212 is communicated with an operation channel 214 through a communication channel 213. A driving support mechanism 25 is arranged in the installation channel 212. The driving support mechanism 25 includes a support roller 251. A lower wedge block 252 is installed on one side of the support roller 251. The lower wedge block 252 is connected with an upper wedge block 254 through a return spring 253. The upper wedge block 254 is connected with a moving driving motor 255. An operating rod 256 is arranged in the operation channel 214. A conical ejecting block 257 is arranged at the bottom of the operating rod 256. The conical ejecting block 257 is arranged opposite to one end of a driving rod 258 in the communication channel 213. A conical separating block 259 is arranged at the other end of the driving rod 258. The conical separating block 259 is arranged between the upper wedge block 254 and the lower wedge block 252. The output end of the moving driving motor 255 is connected with a driving roller 2510. The moving driving motor 255 is electrically connected with the solar tracking controller 22.

[0034] The cross-section of the annular sliding groove 11 is T-shaped. Both the support roller 251 and the driving roller 2510 are arranged in the annular sliding groove 11. Anti-wear balls 27 are embedded at the bottom of the semi-circular mounting bracket 21. At least one strengthening mechanism is connected to the inner side of the semi-circular mounting bracket 21. The strengthening mechanism includes a T-shaped limiting frame 26. One end of the T-shaped limiting frame 26 is threadedly connected to the inner side of the semi-circular mounting bracket 21. Anti-wear balls 27 are arranged on the inner side of the cross bar of the T-shaped limiting frame 26.

[0035] During installation, insert the driving column 211 into the annular sliding groove 11, rotate the operating rod 256, so that the driving rod 258 moves towards the upper wedge block 254 and the lower wedge block 252, separate the upper wedge block 254 and the lower wedge block 252, so that the driving roller 2510 and the support roller 251 extend out of the installation channel 212, and start the moving driving motor 255 to realize the movement of the semi-circular mounting bracket 21 in the annular sliding groove 11.

[0036] As Figure 5 shown, the angle adjustment mechanism 24 includes a connecting plate 241 connected to the semi-circular mounting bracket 21. A first angle adjustment motor 242 is installed on the connecting plate 241. The output shaft of the first angle adjustment motor 242 is connected with a first angle adjustment shaft 243. A connecting block 244 is arranged on the first angle adjustment shaft 243. A second angle adjustment motor 245 is installed on the connecting block 244. The output shaft of the second angle adjustment motor 245 is connected with a second angle adjustment shaft 246. The second angle adjustment shaft 246 is connected with the photovoltaic module 23 through a strengthening plate 247. Both the first angle adjustment motor 242 and the second angle adjustment motor 245 are electrically connected with the solar tracking controller 22.

[0037] A detection component 28 is provided on the semi-circular mounting bracket 21, and each detection component 28 corresponds to each photovoltaic module 23 to realize the detection of the environment where each photovoltaic module 23 is located, such as Figure 6 As shown, the detection component 28 includes a wind sensor, a wind direction sensor, a light angle sensor, and a light intensity sensor. The wind sensor, the wind direction sensor, the light angle sensor, and the light intensity sensor are all electrically connected to the solar tracking controller 22.

[0038] When the light intensity detected by the light intensity sensor is less than the set light intensity, or the wind force detected by the wind sensor is greater than the set wind force value, the photovoltaic module 23 is kept parallel to the section plane of the support tower 1 through the angle adjustment mechanism 24. When the light is relatively weak or the wind force is relatively strong, the photovoltaic module 23 is kept parallel to the section plane of the support tower 1, so that the photovoltaic module 23 is fixed reliably and wind damage is avoided.

[0039] When the light intensity detected by the light intensity sensor is not less than the set light intensity and the wind force detected by the wind sensor is not greater than the set wind force value, the photovoltaic module 23 is kept perpendicular to the light angle through the angle adjustment mechanism 24 and the moving drive motor 255. The power generation efficiency of the photovoltaic power generation is improved.

[0040] In order to realize the transmission of electric energy, the output cable of the photovoltaic module 23 passes through the support tower 1 and is electrically connected to the distribution box in the wind power generation unit (not shown in the figure), and a protective drag chain is provided for the output cable located on the outside. The arrangement of the cable is a conventional setting and will not be described in detail here.

[0041] Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the structure of the angle adjustment mechanism 24 is different. As Figure 7 shown, the angle adjustment mechanism 24 includes a rotary guide plate 248 connected to the semi-circular mounting bracket 21. A movable hinge seat 249 and a fixed telescopic hinge seat 2410 are arranged in the rotary guide plate 248. The movable hinge seat 249 is hinged to the upper part of the photovoltaic module 23, and the fixed telescopic hinge seat 2410 is hinged to the lower part of the photovoltaic module 23. The telescopic member of the fixed telescopic hinge seat 2410 and the rotary angle adjustment motor in the rotary guide plate 248 are both electrically connected to the solar tracking controller 22. It is suitable for the situation where the angle adjustment range is small.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
