DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1-11 A new energy photovoltaic power generation device is shown in the figure.

[0034] Example 1: The present invention employs the following technical solution: A new energy photovoltaic power generation device includes a base 1, on which is rotatably mounted a frame 13 for mounting a photovoltaic panel 31. An energy storage power supply 40 is provided on the base 1, and the photovoltaic panel 31 generates electricity from solar radiation and stores it in the energy storage power supply 40.

[0035] The front and rear ends of the base 1 are fixed with fixed arc blocks 8, and one end of the frame 13 is rotatably mounted between the two fixed arc blocks 8. The tilt angle of the frame 13 can be adjusted according to the angle of sunlight to maximize the intensity of sunlight radiation received by the photovoltaic panel 31, thereby improving power generation efficiency.

[0036] A first limiting assembly and a second limiting assembly are provided on the frame 13. The photovoltaic panel 31 is installed between the first limiting assembly and the second limiting assembly.

[0037] like Figure 6 As shown, the first limiting assembly includes a first fixing block 14 and a second fixing block 20, each of which has two first fixing blocks 14 and two second fixing blocks 20. The two first fixing blocks 14 are respectively fixed at the two corners of the upper right end of the frame 13, and the two second fixing blocks 20 are respectively fixed at the two corners of the upper left end of the frame 13.

[0038] The second limiting assembly includes a first positioning plate 15 and a second positioning plate 25. The first positioning plate 15 is elastically rotatably arranged at the lower right end of the frame 13. Specifically, the first positioning plate 15 is rotatably connected to the frame 13 via a first rotating rod. A first torsion spring is sleeved on the first rotating rod, and the first torsion spring is fixedly connected between the first positioning plate 15 and the frame 13. In a natural state, under the action of the torsion spring, the first positioning plate 15 is in a state of being in contact with the photovoltaic panel 31, thereby limiting the photovoltaic panel 31. A positioning block 16 that cooperates with the first positioning plate 15 is fixedly arranged on the fixed arc block 8. When the frame 13 rotates clockwise, when the frame 13 is in a vertical state, the first positioning plate 15 contacts the positioning block 16. Then, as the first positioning plate 15 continues to rotate, the first positioning plate 15 rotates around the first rotating rod under the blocking action of the positioning block 16, thereby releasing the limit on the photovoltaic panel 31.

[0039] A second positioning plate 25 is rotatably mounted at the lower left end of the frame 13. Specifically, the second positioning plate 25 is rotatably connected to the frame 13 via a second rotating rod. The second positioning plate 25 is fixedly connected to the second rotating rod, which is rotatably connected to the frame 13. A connecting plate 32 is fixedly connected to the left end of the photovoltaic panel 31, which mates with the second positioning plate 25. The second fixing block 20 and the second positioning plate 25 limit the position of the connecting plate 32, thereby limiting the position of the left end of the photovoltaic panel 31.

[0040] A locking assembly is provided between the second positioning plate 25 and the frame 13, and an unlocking assembly is provided on the base 1. The locking assembly locks the second positioning plate 25 to prevent it from accidentally rotating. There are two locking assemblies and two unlocking assemblies, each corresponding to a corresponding unlocking assembly. The unlocking assembly cooperates with the corresponding locking assembly. The unlocking assembly is used to release the restriction imposed on the second positioning plate 25 by the corresponding locking assembly. The two locking assemblies are located at the front and rear ends of the frame 13. The two unlocking assemblies are located at the front and rear ends of the base 1.

[0041] Each locking assembly includes a snap-fitting member that engages with the second positioning plate 25. The snap-fitting member is elastically slidably connected to the frame 13. The snap-fitting member includes a card block 27, a second slide rod 28 and a connecting rod 30. A card plate 26 is fixedly mounted on the second rotating rod. The frame 13 is provided with a receiving cavity and a limiting groove connected to the receiving cavity, and the card plate 26 is located in the receiving cavity. A card slot is provided on the card plate 26, and a card block 27 is slidably set in the card slot. The card block 27 is fixedly connected to the second slide rod 28. After the second slide rod 28 slides through the limiting groove, it extends to the outside of the frame 13 and is fixedly connected to the connecting rod 30. A second spring 29 is sleeved on the second slide rod 28, and the second spring 29 is fixedly connected between the card block 27 and the frame 13. Under the action of the second spring 29, the card block 27 is snapped into the card slot.

[0042] The unlocking assembly is located at the right end of the base 1. Each unlocking assembly includes a vertical plate 42, which is fixed to the base 1. A slide 43 is provided on the vertical plate 42. The slide 43 includes a first groove section and a second groove section. The lower end of the first groove section is connected to the upper end of the second groove section. The upper end of the first groove section is inclined to the left, and the second groove section is arc-shaped and its axis coincides with the rotation axis of the frame 13. The slide 43 cooperates with the connecting rod 30. When the connecting rod 30 is inserted into the slide 43, the connecting rod 30 moves to the right under the guidance of the first groove section, thereby causing the block 27 to slide out of the groove, releasing the limit on the second positioning plate 25. After the block 27 is disengaged from the card plate 26, the connecting rod 30 enters the second groove section.

[0043] A second drive assembly is provided on the base 1 to drive the second positioning plate 25. The second drive assembly includes a fourth rack 44 and a third gear 45. The end of the second rotating rod extends outside the frame 13 and is coaxially fixedly connected to the third gear 45. The fourth rack 44 is fixedly mounted on the riser 42. When the block 27 is disengaged from the plate 26, the third gear 45 engages with the fourth rack 44. Under the action of the fourth rack 44 and the third gear 45, the second positioning plate 25 rotates about the second rotating rod, thereby releasing the position limit on the photovoltaic panel 31.

[0044] Each second fixed block 20 is provided with an ejection assembly. Each ejection assembly includes a ejection block 24, a first slide bar 22, a first spring 23 and a semicircular block 21. A through hole is provided on the second fixed block 20, and the first slide bar 22 is slidably set in the through hole. The ejection block 24 is fixed to one end of the first slide bar 22 close to the second positioning plate 25, and the semicircular block 21 is fixed to one end of the first slide bar 22 away from the second positioning plate 25. The first spring 23 is sleeved on the first slide bar 22, and the first spring 23 is fixedly connected between the semicircular block 21 and the second fixed block 20. The ejection block 24 is in contact with the connecting plate 32. When the semicircular block 21 is squeezed, the ejection block 24 moves, thereby ejecting the photovoltaic panel 31.

[0045] Support assemblies are installed between the front and rear sides of the frame 13 and the base 1. Each support assembly includes an air cylinder 34 and a third slide bar 37 slidably connected to the air cylinder 34. A first rotating block 33 is fixedly connected to the base 1. One end of the air cylinder 34 is rotatably connected to the first rotating block 33, with the rotation axis of the air cylinder 34 parallel to the rotation axis of the frame 13. A piston 36 is fixedly connected to one end of the third slide bar 37, which is sealed and slidably mounted within the air cylinder 34. The other end of the third slide bar 37 is fixedly connected to a second rotating block 38. A fixed shaft 39 is fixedly mounted on the frame 13, and the second rotating block 38 is rotatably sleeved on the fixed shaft 39. A solenoid valve 35 is installed within the air cylinder 34. When the solenoid valve 35 is opened and the frame 13 rotates clockwise, the third slide bar 37 slides outward from the air cylinder 34, allowing outside air to enter the air cylinder 34 through the solenoid valve 35. When the frame 13 stops rotating, the solenoid valve 35 closes, and the support assembly supports the frame 13.

[0046] The base 1 is further provided with a controller 41 , and the energy storage power supply 40 , the solenoid valve 35 , and the photovoltaic panel 31 are all electrically connected to the controller 41 .

[0047] Working Principle: Initially, the second spring 29 forces the locking block 27 into the slot, locking the second positioning plate 25. The first torsion spring forces the first positioning plate 15 to rest against the photovoltaic panel 31. The photovoltaic panel 31 is positioned between the first fixing block 14, the first positioning plate 15, the second fixing block 20, and the second positioning plate 25. The frame 13 is positioned to the left of the fixed arc block 8. The first and second fixing blocks 14 and 20 are positioned above the photovoltaic panel 31, while the first and second positioning plates 15 and 25 are positioned below it.

[0048] Adjust the position of the base 1 so that the photovoltaic panel 31 faces the sunlight. Then, rotate the frame 13 to adjust the tilt angle of the photovoltaic panel 31 to maximize the intensity of sunlight received by the photovoltaic panel 31 and improve power generation efficiency. However, when adjusting the tilt angle of the photovoltaic panel 31, the rotation angle of the rotating frame 13 should be less than 90 degrees.

[0049] When the photovoltaic panel 31 needs to be replaced, the frame 13 is rotated clockwise. When the frame 13 is in a vertical state, the first positioning plate 15 contacts the positioning block 16. Then, as the frame 13 continues to rotate, the first positioning plate 15 rotates around the first rotating rod under the obstruction of the positioning block 16, thereby gradually releasing the first positioning plate 15 from limiting the photovoltaic panel 31.

[0050] As the frame 13 continues to rotate, it is positioned to the right of the fixed arc block 8. The connecting rod 30 gradually approaches the chute 43. Once inside, it slides along the chute 43. Guided by the chute 43, the connecting rod 30 moves rightward relative to the frame 13, causing the locking block 27 to slide out of the chute, disengaging from the locking plate 26 and releasing the lock on the second positioning plate 25.

[0051] When the second positioning plate 25 is unlocked, the third gear 45 engages with the fourth rack 44 , and the second positioning plate 25 rotates around the second rotating rod to release the position restriction on the photovoltaic panel 31 .

[0052] Then, as the frame 13 continues to rotate, the semicircular block 21 is squeezed by the base 1, and the top block 24 pushes out the photovoltaic panel 31, making it easy to remove the photovoltaic panel 31. Then, a new photovoltaic panel 31 is placed in the frame 13 and above the first fixing block 14 and the top block 24.

[0053] Subsequently, the frame 13 is rotated counterclockwise, and the semicircular block 21 gradually disengages from the base 1. The top block 24 moves away from the connecting plate 32, and the photovoltaic panel 31 gradually contacts the second fixed block 20. Under the action of the fourth rack 44 and the third gear 45, the second positioning plate 25 rotates around the second rotating rod and contacts the photovoltaic panel 31, thereby limiting the position of the photovoltaic panel 31. At the same time, the connecting rod 30 gradually slides outward along the slide 43. When the third gear 45 disengages from the fourth rack 44, the block 27 is aligned with the slot. As the connecting rod 30 moves out of the slide 43, the block 27 is re-engaged in the slot under the action of the second spring 29.

[0054] As the frame 13 continues to rotate, when the first positioning plate 15 is disengaged from the positioning block 16 , the first positioning plate 15 rotates around the first rotating rod under the action of the first torsion spring and comes into close contact with the photovoltaic panel 31 , thereby limiting the position of the photovoltaic panel 31 .

[0055] It should be noted that when the frame 13 rotates, the solenoid valve 35 needs to be opened so that the third slide bar 37 can slide smoothly along the air cylinder 34, so that the frame 13 can rotate smoothly.

[0056] Example 2: This example improves upon Example 1. A reflector 7 is rotatably mounted on the base 1. The photovoltaic panel 31 is a double-sided panel. The front of the panel 31 directly receives sunlight, while the reflector 7 reflects sunlight to the back of the panel 31. This allows the panel 31 to receive more sunlight, thereby improving power generation efficiency and increasing power generation. A support assembly is provided between the reflector 7 and the base 1.

[0057] Example 3: This embodiment is a further improvement based on Example 2.

[0058] The base 1 is provided with a first driving assembly for driving the reflector 7 and the frame 13 to rotate simultaneously. There are two first driving assemblies, which are respectively provided on the front and rear sides of the base 1.

[0059] Each first drive assembly includes a first electric push rod 2. The first electric push rod 2 is arranged horizontally, and the output end of the first electric push rod 2 is fixedly connected to a first rack 3, which is fixedly connected to a connecting shaft 4, which is fixedly connected to a second rack 5. The first rack 3 and the second rack 5 are both horizontally slidably mounted on the base 1. A first gear 6, which meshes with the first rack 3, is fixedly mounted on the end of the reflector 7. A rotating shaft 9 is rotatably connected between the two fixed arc blocks 8. A second gear 10 is coaxially fixedly connected to the rotating shaft 9, and the second gear 10 meshes with the second rack 5.

[0060] A rotation slot is defined in the frame 13, through which the frame 13 is sleeved on the rotating shaft 9. A stopper 11 is fixedly mounted on the outer circumference of the rotating shaft 9, which is in sliding contact with the inner wall of the rotation slot. A mating block 12 is fixedly mounted in the rotating slot, which engages with the stopper 11. When the rotating shaft 9 rotates, the stopper 11 and the mating block 12 drive the frame 13 to rotate. A toothless gear 17 is rotatably sleeved on the rotating shaft 9, which is fixedly connected to the frame 13. A third rack 18 is movably mounted on the base 1, which engages with the toothless gear 17. A second electric push rod 19 is fixedly mounted on the base 1, and the output end of the second electric push rod 19 is fixedly connected to the third rack 18. Both the first electric push rod 2 and the second electric push rod 19 are electrically connected to the controller 41.

[0061] When adjusting the inclination angle of the frame 13, the first rack 3 and the second rack 5 are moved simultaneously by the first electric push rod 2, and the first gear 6 and the second gear 10 are rotated simultaneously, thereby rotating the reflector 7. At the same time, the rotating shaft 9 drives the frame 13 to rotate through the matching block 12 and the stop block 11, thereby achieving the purpose of simultaneously adjusting the inclination angle of the reflector 7 and the frame 13.

[0062] When the photovoltaic panel 31 needs to be replaced, the frame 13 is first rotated to a vertical position by the first electric push rod 2. When the frame 13 is rotated to the vertical position, the second gear 10 is disengaged from the second rack 5, and the toothless gear 17 is engaged with the third rack 18. Then, the first electric push rod 2 is stopped and the second electric push rod 19 is started. The third rack 18 moves, and the toothless gear 17 rotates, thereby causing the frame 13 to continue to rotate clockwise.

[0063] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
