Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and specifically to a photovoltaic power generation device and a vehicle. Background Art

[0002] Applying photovoltaic technology to vehicles is a technological trend. Especially in low-latitude areas with sufficient sunlight, this technology has been widely promoted and applied. During the actual application process, the driving direction of the vehicle constantly changes, and the photovoltaic modules in the vehicle-mounted photovoltaic power generation device are affected by the changing sunlight, which affects the power generation efficiency. Therefore, it is necessary to appropriately adjust the inclination angle of the photovoltaic modules according to the sunlight irradiation angle.

[0003] On the other hand, there is a large amount of sand and dust in desert areas. Since the photovoltaic modules do not generate electricity at night, it is necessary to store the photovoltaic modules to reduce the damage of sand and dust to the photovoltaic modules. When the vehicle drives into the block, it may also be necessary to store the photovoltaic modules to avoid colliding with buildings or pedestrians.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The orientation terms such as front, rear, left, and right mentioned in this embodiment generally take the [accompanying drawings] as the reference benchmark. Figure 1 as the reference benchmark.

[0051] Please refer to Figures 1-11 , an embodiment of the present invention provides a photovoltaic power generation device, including a photovoltaic module and a driving mechanism. The photovoltaic module includes a first photovoltaic cell 4 and a second photovoltaic cell 5, and the second photovoltaic cell 5 can be folded on the first photovoltaic cell 4. The driving mechanism is used to drive the folding of the second photovoltaic cell 5. For example, the second photovoltaic cell 5 is rotatably connected to the first photovoltaic cell 4 through a pivot, and the driving mechanism drives the second photovoltaic cell 5 to rotate around the pivot, driving the second photovoltaic cell 5 to fold or unfold. In a specific scenario (night or bad weather or narrow area), the second photovoltaic cell 5 is folded to reduce the spreading area of the photovoltaic module, which can protect the photovoltaic module and reduce the risk of damage to the photovoltaic module. Using the back surface (non-light-receiving surface) of the second photovoltaic cell to cover and protect the front surface (light-receiving surface) of the first photovoltaic cell can further avoid damage caused by bad weather (sandstorms, hailstorms, etc).

[0052] In some embodiments, the aforementioned photovoltaic power generation device further includes a base 1 and an angle adjustment mechanism. The base 1 is used for fixedly connecting with an external device. For example, the base 1 is fixedly connected to the top of a vehicle. The angle adjustment mechanism includes a support frame 2 rotatably connected to the base 1. A positioning rotating shaft 3 is arranged on the support frame 2, and the positioning rotating shaft 3 is connected to the photovoltaic module to adjust the inclination angle of the photovoltaic module by the rotation of the support frame 2. By providing the angle adjustment mechanism, the inclination angle of the photovoltaic module can be adjusted, which can increase the direct sunlight time and improve the power generation efficiency.

[0053] In some embodiments, the base 1 has a "return" - shaped structure. A first positioning seat 6 is fixedly installed on the inner wall of the front side of the base 1. The first positioning seat 6 is rotatably connected to the support frame 2. A second positioning seat 7 is fixedly installed at the rear end of the support frame 2. An electric push rod 8 is rotatably connected to the inner wall of the rear side of the base 1. The front end of the electric push rod 8 is rotatably connected to the second positioning seat 7. The photovoltaic module is supported by the support frame 2 and the positioning rotating shaft 3. At the same time, the telescopic movement of the electric push rod 8 can push the support frame to rotate around the first positioning seat, thereby changing the inclination angle of the photovoltaic module.

[0054] In some embodiments, limiting shafts 9 are fixedly installed at both ends of the support frame 2. Limiting grooves 10 are formed on the left and right sides of the base 1. The limiting shafts 9 penetrate into the interior of the limiting grooves 10, and the limiting shafts 9 are slidably connected to the limiting grooves 10 to limit the stroke of the limiting shafts 9, thereby limiting the rotation angle of the support frame 2. By the cooperation of the limiting shafts 9 and the limiting grooves 10, the rotation stability of the support frame 2 can be improved, so that the photovoltaic module can rotate synchronously with the sun, thereby improving the power generation efficiency. In addition, it can prevent the electric push rod 8 from pushing the support frame 2 into a mechanical dead - point position, resulting in jamming.

[0055] In some embodiments, the drive mechanism includes a power motor 11 and transmission components.

[0056] A power motor 11 is installed at the upper end of the support frame 2. A first gear 12 is fixedly installed at the upper end of the power motor 11. A second gear 13 is rotatably arranged on the positioning rotating shaft 3, and the second gear 13 is meshed with the first gear 12.

[0057] Fixing frames 22 are fixedly installed on the left and right sides of the first photovoltaic cell 4. Two groups of positioning rods 23 are symmetrically connected to one end of the second photovoltaic cell 5 close to the first photovoltaic cell 4. The positioning rods 23 are rotatably connected to the fixing frames 22.

[0058] A drive worm gear 24 is fixed to the front end of the positioning rod 23, and a drive worm 25 is rotatably connected to the middle of the front end fixing bracket 22. The drive worm 25 is meshed with the drive worm gear 24. A fixing seat 19 is connected to the front end of the first photovoltaic cell 4. The fixing seat 19 is rotatably connected to a second rotating shaft 20. Two fourth bevel gears 27 are fixed to both ends of the second rotating shaft 20. A third bevel gear 26 is fixed to the lower end of the drive worm 25. The third bevel gear 26 is meshed with the fourth bevel gear 27.

[0059] A second bevel gear 21 is fixedly connected to the middle of the second rotating shaft 20. A first rotating shaft 16 is rotatably connected to the lower middle part of the first photovoltaic cell 4. A first bevel gear 18 is fixed to the upper end of the first rotating shaft 16. The upper end of the first bevel gear 18 is meshed with the second bevel gear 21. A drive ring 14 is sleeved on the middle part of the positioning rotating shaft 3. The drive ring 14 is of a hub structure. The central part of the drive ring 14 is fixedly connected to the second gear 13. The central hole of the drive ring 14 is coaxially arranged with the second gear 13, so that the drive ring 14 can rotate synchronously with the second gear 13. A drive rack 15 is fixed to the inner wall of the drive ring 14. The drive rack 15 is arranged in an arc shape. A drive gear 17 is fixed to the lower end of the first rotating shaft 16. The drive rack 15 is meshed with the drive gear 17.

[0060] The transmission components at least include a first gear 12, a second gear 13, a drive worm gear 24, a drive worm 25, a third bevel gear 26, a fourth bevel gear 27, a first bevel gear 18, a second bevel gear 21, a drive rack 15 and a drive gear 17.

[0061] With the above technical solution, through the cooperation between the drive worm 25 and the drive worm gear 24, when the drive worm 25 rotates, it can drive the drive worm gear 24 and the positioning rod 23 to rotate synchronously. The positioning rod 23 is used to drive the second photovoltaic cell 5 to rotate, so as to facilitate the folding of the second photovoltaic cell 5. At the same time, by means of the cooperation of the third bevel gear 26, the fourth bevel gear 27 and the second rotating shaft 20, it can be ensured that the two drive worms 25 rotate synchronously. Through the cooperation of the drive ring 14, the drive rack 15 and the drive gear 17, the drive rack 15 is used to drive the drive gear 17 and the first rotating shaft 16 to rotate, and the first rotating shaft 16, the first bevel gear 18 and the second bevel gear 21 are used to drive the second rotating shaft 20 to rotate synchronously. Through the layout of the above transmission components, the folding of two second photovoltaic cells 5 can be driven by one power motor 11, which saves costs. In addition, the reasonable layout of the transmission components avoids interference. Moreover, the drive mechanism is arranged below the photovoltaic module, which reduces the center of gravity of the entire photovoltaic power generation device and reduces the risk of the photovoltaic power generation device tipping over.

[0062] In some embodiments, the photovoltaic power generation device further includes a cleaning mechanism. The cleaning mechanism includes a first cleaning plate 28 for wiping the upper surface of the first photovoltaic cell 4, and the first cleaning plate 28 is movably and conformally arranged on the upper surface of the first photovoltaic cell 4. The cleaning mechanism includes a second cleaning plate 33 for wiping the upper surface of the second photovoltaic cell 5, and the second cleaning plate 33 is movably and conformally arranged on the upper surface of the second photovoltaic cell 5. The cleaning mechanism can clean at least one of the first photovoltaic cell 4 and the second photovoltaic cell 5, which can ensure the surface cleanliness of the first photovoltaic cell 4 and / or the second photovoltaic cell 5, avoid affecting the light illumination effect due to dust pollution and other situations, and further affect the power generation efficiency.

[0063] In some embodiments, the power generated when the second photovoltaic cell 5 folds is converted into the power for the first cleaning plate 28 to move on the first photovoltaic cell 4. The power generated when the second photovoltaic cell 5 folds is converted into the power for the second cleaning plate 33 to move on the second photovoltaic cell 5. With the above technical solution, through the design of the first cleaning plate 28 and the second cleaning plate 33, the surfaces of the first photovoltaic cell 4 and the second photovoltaic cell 5 can be cleaned respectively when they are moving. By driving two second photovoltaic cells 5 to fold with a single power motor 11, while driving the first cleaning plate 28 and / or the second cleaning plate 33 to move, the use of the driving source is further saved and the cost is reduced.

[0064] In some embodiments, the lower end of the first cleaning plate 28 is in contact with the surface of the first photovoltaic cell 4, both ends of the first cleaning plate 28 are slidably connected to the upper end of the first photovoltaic cell 4, a connecting plate 29 is fixed to the upper end of the first cleaning plate 28, a transmission link 30 is rotatably connected to the upper end of the connecting plate 29, a receiving groove 32 is formed in the middle of the second photovoltaic cell 5 on the right side, the transmission link 30 is embedded inside the receiving groove 32, and a support rod 31 is fixed inside the right side of the receiving groove 32, and the left end of the support rod 31 is rotatably connected to the transmission link 30.

[0065] When the first photovoltaic cell 4 on the right side rotates, it can drive the transmission link 30 to rotate synchronously and push the first cleaning plate 28 to move on the upper surface of the first photovoltaic cell 4, thereby cleaning the first photovoltaic cell 4 and ensuring the cleanliness of the surface of the first photovoltaic cell 4 to ensure the power generation efficiency.

[0066] In some embodiments, the first cleaning plate 28 is slidably connected to the first photovoltaic cell 4, both ends of the second cleaning plate 33 are slidably connected to the second photovoltaic cell 5, both ends of the second photovoltaic cell 5 are fixedly connected with sliding guide rods 34, the sliding guide rods 34 are slidably connected to the second cleaning plate 33, and the middle of the second cleaning plate 33 is designed in a "U" shape, and the transmission link 30 is embedded in the "U" shape in the middle of the second cleaning plate 33.

[0067] With the above technical solution, the second cleaning plate 33 can clean the second photovoltaic cell 5 during the movement. The middle part of the second cleaning plate 33 is U-shaped, which can avoid blocking the rotation of the transmission connecting rod 30 and ensure that the transmission connecting rod 30 can be effectively stored inside the storage groove 32 after the second photovoltaic cell 5 is folded.

[0068] In some embodiments, the rear end of the second cleaning plate 33 is rotatably connected to a first connecting seat 35. The rear end of the first connecting seat 35 penetrates through the rear end of the second photovoltaic cell 5. The first connecting seat 35 is slidably connected to the second photovoltaic cell 5. A tension spring 36 is fixed to the outer wall of the first connecting seat 35. The end of the tension spring 36 is fixed to a second connecting seat 38. The middle part of the rear side of the first photovoltaic cell 4 is connected to a fixing plate 37. The second connecting seat 38 is rotatably connected to the fixing plate 37.

[0069] With the above technical solution, by utilizing the cooperation among the first connecting seat 35, the second connecting seat 38 and the tension spring 36, during the rotation of the second photovoltaic cell 5, the tension spring 36 can be used to pull the first connecting seat 35 to move, thereby driving the second cleaning plate 33 to clean the second photovoltaic cell 5. After the second photovoltaic cell 5 is unfolded, the tension spring 36 is used again to pull the first connecting seat 35 and the second cleaning plate 33 to reset.

[0070] An embodiment of the present invention further provides a vehicle, including the aforementioned photovoltaic power generation device. The base 1 of the photovoltaic power generation device is fixedly connected to the top of the vehicle. During the driving of the vehicle, according to the change of the illumination angle, the inclination angle of the photovoltaic module can be adjusted. According to the needs of the scenario, the photovoltaic module can be unfolded or stored.

[0071] In other embodiments, the positioning rotating shaft 3 is rotatably connected to the support frame 2. A second gear 13 is fixedly arranged on the positioning rotating shaft 3. The second gear 13 is meshed with the first gear 12, so that the positioning rotating shaft 3 and the second gear 13 rotate synchronously, thereby driving the photovoltaic module to rotate and further improving the illumination effect. At this time, the transmission failure needs to be considered, so the transmission components need to be reasonably designed. When the photovoltaic module rotates, it will be folded synchronously, which will also affect the illumination effect. Therefore, the transmission components also need to be reasonably designed to obtain a better illumination effect.
