[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 13As shown, this embodiment proposes a concentrated photovoltaic power generation system, including a fixed frame 1, a rotating frame 2, a circumferential adjustment component, a swing frame 3, a convex lens 4, a power generation component, an angle adjustment component, a limit component and a cleaning component. The rotating frame 2 is rotatably installed on the upper part of the fixed frame 1, and the circumferential adjustment component is installed on the fixed frame 1 to adjust the circumferential position of the rotating frame 2. The circumferential adjustment component includes a first gear ring 5, a first motor 6 and a first gear 7. The first gear ring 5 is fixedly sleeved on the bottom end of the rotating frame 2, and the first motor 6 is fixedly installed on the fixed frame 1. The output end of the first motor 6 is fixedly installed with a first gear 7, and the first gear 7 is meshed with the first gear ring 5.

[0025] Specifically, in the process of using the power generation component to generate electricity, the convex lens 4 is used to focus sunlight on the power generation component to start power generation. In order to ensure that the convex lens 4 always maintains the best working position, it is necessary to adjust the position of the convex lens 4 and the power generation component according to the position of the sun. At this time, the first motor 6 is started, and the first motor 6 drives the first gear 7 to rotate, and the first gear 7 drives the first gear ring 5 to rotate, thereby driving the rotating frame 2 to rotate, and then driving the convex lens 4 to rotate through the swing frame 3. In conjunction with the angle adjustment component, the position of the convex lens 4 and the power generation component can be adjusted. Through the setting of the limit component, the position of the swing frame 3 can be quickly and stably controlled, making the entire structure more stable and reliable. At night, the swing frame 3 is turned over, and the cleaning component is started to clean it.

[0026] like Figure 4 , Figure 5 As shown, the swing frame 3 is rotatably mounted on the top of the rotating frame 2, a convex lens 4 is detachably mounted on the top of the swing frame 3, and a power generation assembly is mounted on the bottom of the swing frame 3 for generating electricity. The power generation assembly includes a fixed cylinder 8, a sliding cylinder 9, a loading plate 10, a photovoltaic power generation panel 11, a second motor 12, a first screw 13 and a first nut 14. The fixed cylinder 8 is fixedly mounted on the lower part of the swing frame 3, and the axial position of the fixed cylinder 8 coincides with the axial position of the convex lens 4. The sliding cylinder 9 is slidably mounted on the fixed cylinder 8, the loading plate 10 is fixedly mounted on the top of the sliding cylinder 9, the photovoltaic power generation panel 11 is fixedly mounted on the loading plate 10, the second motor 12 is fixedly mounted on the fixed cylinder 8, the first screw 13 is fixedly mounted on the output end of the second motor 12, and the first nut 14 is threadedly sleeved on the first screw 13, and the first nut 14 is fixedly connected to the sliding cylinder 9.

[0027] Specifically, when power generation starts, in order to optimize the power generation efficiency, the second motor 12 is started, the second motor 12 drives the first screw 13 to rotate, the first screw 13 drives the first nut 14 to move, and the first nut 14 drives the sliding cylinder 9 to move on the fixed cylinder 8, thereby driving the photovoltaic panel 11 to move through the loading plate 10, thereby moving the photovoltaic panel 11 to the focus of the convex lens 4, thereby improving the power generation efficiency.

[0028] like Figures 6 to 8 As shown, the angle adjustment assembly is installed on the rotating frame 2, and is used to adjust the angle position of the swing frame 3. The angle adjustment assembly includes an adjustment frame 15, a second gear ring 16, a second gear 17, a driving unit and a transmission unit. Two adjustment frames 15 are symmetrically and fixedly installed on the rotating frame 2. The two adjustment frames 15 are close to the top of the rotating frame 2. The second gear ring 16 is rotatably installed on the rotating frame 2. The second gear 17 is rotatably installed on the two adjustment frames 15. The two second gears 17 are meshed with the second gear ring 16. The driving unit is installed on one of the adjustment frames 15, and is used to drive one of the second gears 17 to rotate. The transmission unit is installed on the other adjustment frame 15, and is used to drive the other second gear 17 to rotate in the opposite direction.

[0029] Specifically, when adjusting the circumferential position of the swing frame 3 and the photovoltaic panel 11 through the rotating frame 2, it is also necessary to adjust their angles. At this time, through the setting of the driving part, the second gear 17 drives the second gear ring 16 to rotate, and then through the setting of the transmission part, the angle of the swing frame 3 can be adjusted, so that the convex lens 4 is always facing the sun, the focusing accuracy is improved, the power generation process of the photovoltaic panel 11 is more stable and continuous, and the power generation efficiency is improved.

[0030] The above, such as Figure 7 As shown, the driving part includes a driving frame 18, a transmission frame 19, a third motor 20 and a friction wheel 21. The driving frame 18 is fixedly mounted on one of the adjusting frames 15, the transmission frame 19 is fixedly mounted on the other adjusting frame 15, the third motor 20 is fixedly mounted on the driving frame 18, and the friction wheel 21 is fixedly mounted on the output end of the third motor 20. The friction wheel 21 is fixedly connected to the second gear 17 close to the third motor 20, wherein the second gear 17 close to the third motor 20 is fixedly connected to the swing frame 3.

[0031] Specifically, when adjusting the angle of the swing frame 3 and the photovoltaic panel 11, it is necessary to adjust the angle of the swing frame 3. At this time, the third motor 20 is started, and the third motor 20 drives the friction wheel 21 to rotate. The friction wheel 21 drives the corresponding second gear 17 to rotate, and then drives the second gear ring 16 to rotate, thereby driving the other second gear 17 to rotate. Since the two second gears 17 are in a state of reverse rotation at this time, the swing frame 3 can be driven to swing through the setting of the transmission part.

[0032] The above, such as Figure 8 As shown, the transmission part includes a first bevel gear 22, a second bevel gear 23, an intermediate bevel gear 24 and a transmission shaft 25. The first bevel gear 22 is fixedly mounted on the second gear 17 away from the third motor 20, the second bevel gear 23 is rotatably mounted inside the transmission frame 19, the intermediate bevel gear 24 is rotatably mounted on the inner top wall of the transmission frame 19, and the intermediate bevel gear 24 is respectively meshed with the first bevel gear 22 and the second bevel gear 23, wherein the first bevel gear 22 and the second bevel gear 23 are symmetrically arranged relative to the intermediate bevel gear 24, a transmission shaft 25 is fixedly mounted on the second bevel gear 23, the other end of the transmission shaft 25 is fixedly connected to the swing frame 3, and the transmission shaft 25 is rotatably matched with the first bevel gear 22 and the second gear 17.

[0033] Specifically, as the second gear ring 16 rotates, the second gear ring 16 drives the second gear 17 away from the third motor 20 to rotate, thereby driving the first bevel gear 22 to rotate, the first bevel gear 22 drives the middle bevel gear 24 to rotate, and the middle bevel gear 24 drives the second bevel gear 23 to rotate. The cooperation between the first bevel gear 22, the second bevel gear 23 and the middle bevel gear 24 can make the direction of the second bevel gear 23 the same as the direction of the second gear 17 close to the third motor 20. At this time, through the setting of the transmission shaft 25, the second gear 17 can cooperate with the swing frame 3 to swing.

[0034] like Fig. 9 , Fig.13 As shown, the limit assembly is installed inside the angle adjustment assembly and is used to fix the position of the swing frame 3. The limit assembly includes a first electric cylinder 26, a displacement frame 27, a friction block 28 and a first spring 29. Two first electric cylinders 26 are symmetrically and fixedly installed on the inner bottom wall of the driving frame 18. The output ends of the two first electric cylinders 26 are fixedly installed with displacement frames 27. The friction blocks 28 are rotatably installed on the two displacement frames 27. The two friction blocks 28 are symmetrically arranged relative to the friction wheel 21. The first springs 29 are fixedly installed on the two displacement frames 27, and the other ends of the first springs 29 are fixedly connected to the friction blocks 28.

[0035] Specifically, when the swing frame 3 swings in one direction, a corresponding first electric cylinder 26 is started, the first electric cylinder 26 drives the displacement frame 27 to move, and the displacement frame 27 drives the friction block 28 to move until the friction block 28 contacts the friction wheel 21. At this time, as the friction wheel 21 rotates, the friction block 28 will rub against the friction wheel 21. At this time, the friction block 28 will not affect the normal rotation of the friction wheel 21. When the position of the swing frame 3 is adjusted, the friction wheel 21 stops rotating at this time, and the corresponding friction block 28 is set to prevent the friction wheel 21 from reversing. Through the setting of the first spring 29, the friction block 28 can be firmly pressed on the friction wheel 21 to increase the friction wheel 21 and improve the stability during work. When it is necessary to lock the friction wheel 21, the two first electric cylinders 26 are started at the same time to make the two friction blocks 28 contact the friction wheel 21.

[0036] like Figures 10 to 12 As shown, the cleaning component is installed on the fixed frame 1, and is used to clean the convex lens 4. The cleaning component includes a supporting frame 30, a second electric cylinder 31, a movable frame 32, a mounting frame 33, a loading frame 34, a moving part and a cleaning part. The supporting frame 30 is fixedly installed inside the fixed frame 1, and the second electric cylinder 31 is fixedly installed inside the supporting frame 30. The movable frame 32 is slidably installed on the supporting frame 30, and the movable frame 32 is fixedly connected to the output end of the second electric cylinder 31. The mounting frame 33 is fixedly installed on the top of the movable frame 32, and the loading frame 34 is slidably installed on the top of the movable frame 32. The moving part is installed inside the mounting frame 33, and is used to drive the loading frame 34 to move. The cleaning part is installed on the loading frame 34, and is used to clean the convex lens 4.

[0037] Specifically, when the convex lens 4 needs to be cleaned, the swing frame 3 is first reversed through the cooperation of the second gear 17 and the second gear ring 16, so that the convex lens 4 is facing the position of the carrier frame 30, and the second electric cylinder 31 is started at this time. The second electric cylinder 31 drives the movable frame 32 to move until the movable frame 32 is moved to the working position. At this time, the cleaning part on the carrier frame 34 is moved to the working position, and the first motor 6 is restarted at this time. The first motor 6 drives the first gear ring 5 to rotate through the first gear 7, and the first gear ring 5 drives the rotating frame 2 to rotate, thereby driving the rotating frame 2 to rotate, and then driving the convex lens 4 to rotate. At this time, the convex lens 4 and the cleaning part move relative to each other, and the moving part is started at the same time to slowly drive the cleaning part to move, so as to clean the convex lens 4.

[0038] The above, such as Fig.11As shown, the moving part includes a fourth motor 35, a moving cylinder 36, a second screw 37 and a second nut 38. The fourth motor 35 is fixedly installed inside the mounting frame 33, the moving cylinder 36 is slidably installed on the mounting frame 33, the second screw 37 is fixedly installed at the output end of the fourth motor 35, the second nut 38 is threadedly sleeved on the second screw 37, and the second nut 38 is fixedly connected to the moving cylinder 36.

[0039] Specifically, when driving the carrier 34 to move, the fourth motor 35 is started, the fourth motor 35 drives the second screw 37 to rotate, the second screw 37 drives the second nut 38 to move, and the second nut 38 drives the moving cylinder 36 to move, thereby driving the carrier 34 to move.

[0040] The above, such as Fig.12 As shown, the cleaning part includes a cleaning frame 39, a third electric cylinder 40, a support 41, an arc frame 42, a second spring 43 and a hook-shaped scraper 44. The cleaning frame 39 is slidably mounted on the carrier frame 34, the third electric cylinder 40 is fixedly mounted on the carrier frame 34, the output end of the third electric cylinder 40 is fixedly connected to the cleaning frame 39, the support 41 is fixedly mounted on the top of the cleaning frame 39, the arc frame 42 is rotatably mounted on the support 41, the second springs 43 are fixedly mounted on both sides of the support 41, the second springs 43 are fixedly connected to the arc frame 42, and the hook-shaped scraper 44 is fixedly mounted on the top of the arc frame 42.

[0041] Specifically, when cleaning the convex lens 4, after the movable frame 32 moves to the working position, the third electric cylinder 40 is started, and the third electric cylinder 40 drives the cleaning frame 39 to move on the carrier 34, and the cleaning frame 39 drives the support 41 to move, and the support 41 drives the arc frame 42 to move, and the arc frame 42 drives the hook scraper 44 to move until the configuration scraper contacts the convex lens 4. At this time, the opening direction of the hook scraper is opposite to the rotation direction of the convex lens 4. As the carrier 34 slowly moves to the position of the mounting frame 33, since the arc plate and the hook scraper both have a certain elasticity, under the action of the second spring 43, the hook scraper can be pressed on the convex lens 4. During the cleaning process, the scraped impurities will be caught by the opening of the hook scraper, thereby preventing the scraped impurities from adhering to the convex lens 4 again, thereby improving the cleaning efficiency and quality, and the cleaned impurities will fall to the top of the movable frame 32, and can be collected and cleaned regularly.

[0042] To sum up, in the process of using the photovoltaic panel 11 to generate electricity, the convex lens 4 is used to focus sunlight on the photovoltaic panel 11, thereby starting power generation. When starting power generation, in order to optimize the power generation efficiency, the second motor 12 is started at this time, and the second motor 12 drives the first screw 13 to rotate, and the first screw 13 drives the first nut 14 to move, and the first nut 14 drives the sliding cylinder 9 to move on the fixed cylinder 8, thereby driving the photovoltaic panel 11 to move through the loading plate 10, thereby moving the photovoltaic panel 11 to the focus of the convex lens 4, thereby improving the power generation efficiency. In order to ensure that the convex lens 4 always maintains the best working position, it is necessary to adjust the position of the convex lens 4 and the photovoltaic panel 11 according to the position of the sun. At this time, the first motor 6 is started, and the first motor 6 drives the first gear 7 to rotate, and the first gear 7 drives the first gear ring 5 to rotate, thereby driving the rotating frame 2 to rotate.

[0043] When adjusting the circumferential position of the swing frame 3 and the photovoltaic panel 11 by the rotating frame 2, it is also necessary to adjust their angles. When adjusting the angles of the swing frame 3 and the photovoltaic panel 11, it is necessary to adjust the angle of the swing frame 3. At this time, the third motor 20 is started, and the third motor 20 drives the friction wheel 21 to rotate. The friction wheel 21 drives the corresponding second gear 17 to rotate, and then drives the second gear ring 16 to rotate, thereby driving the other second gear 17 to rotate. Since the two second gears 17 are in a state of reverse rotation at this time, as the second gear 17 away from the third motor 20 rotates, it drives the first bevel gear 22 to rotate. Rotate, the first bevel gear 22 drives the middle bevel gear 24 to rotate, and the middle bevel gear 24 drives the second bevel gear 23 to rotate. The cooperation among the first bevel gear 22, the second bevel gear 23 and the middle bevel gear 24 can make the direction of the second bevel gear 23 the same as the direction of the second gear 17 close to the third motor 20. At this time, through the setting of the transmission shaft 25, the second gear 17 can be cooperated to drive the swing frame 3 to swing, and the angle of the swing frame 3 can be adjusted, so that the convex lens 4 is always facing the sun, which improves the focusing accuracy, makes the power generation process of the photovoltaic panel 11 more stable and continuous, and improves the power generation efficiency.

[0044] At the same time, when the swing frame 3 swings in one direction, a corresponding first electric cylinder 26 is started, the first electric cylinder 26 drives the displacement frame 27 to move, and the displacement frame 27 drives the friction block 28 to move until the friction block 28 contacts the friction wheel 21. At this time, as the friction wheel 21 rotates, the friction block 28 will rub against the friction wheel 21. At this time, the friction block 28 will not affect the normal rotation of the friction wheel 21. When the position of the swing frame 3 is adjusted, the friction wheel 21 stops rotating at this time, and the corresponding friction block 28 is set to prevent the friction wheel 21 from reversing. Through the setting of the first spring 29, the friction block 28 can be firmly pressed on the friction wheel 21 to increase the friction wheel 21 and improve the stability during work. When it is necessary to lock the friction wheel 21, the two first electric cylinders 26 are started at the same time to make the two friction blocks 28 contact the friction wheel 21.

[0045] When it is necessary to clean the convex lens 4, the swing frame 3 is first reversed through the cooperation of the second gear 17 and the second gear ring 16, so that the convex lens 4 is facing the position of the carrier frame 30, and the second electric cylinder 31 is started at this time, and the second electric cylinder 31 drives the moving frame 32 to move. After the moving frame 32 is moved to the working position, the third electric cylinder 40 is started, and the third electric cylinder 40 drives the cleaning frame 39 to move on the carrier frame 34, and the cleaning frame 39 drives the support 41 to move, and the support 41 drives the arc frame 42 to move, and the arc frame 42 drives the hook scraper 44 to move until the configuration scraper contacts the convex lens 4. At this time, the opening direction of the hook scraper is opposite to the rotation direction of the convex lens 4, and the third electric cylinder 40 is started. Four motors 35, the fourth motor 35 drives the second screw 37 to rotate, the second screw 37 drives the second nut 38 to move, and the second nut 38 drives the moving cylinder 36 to move, thereby driving the carrier 34 to move. As the carrier 34 slowly moves to the position of the mounting frame 33, since the arc plate and the hook scraper both have a certain elasticity, under the action of the second spring 43, the hook scraper can be pressed onto the convex lens 4. During the cleaning process, the scraped impurities will be caught by the opening of the hook scraper, thereby preventing the scraped impurities from adhering to the convex lens 4 again, thereby improving the cleaning efficiency and quality, and the cleaned impurities will fall to the top of the moving frame 32 and can be collected and cleaned regularly.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
