Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, specifically a self-regulating water surface photovoltaic power generation device. Background Technology

[0002] Floating photovoltaic power generation equipment refers to a photovoltaic power generation system installed on the water surface. Multiple photovoltaic panels are fixed on floating blocks and then distributed on the water surface, or solar panels are fixed by driving piles. In the latter case, the solar panels are fixed on floating blocks and distributed on the water surface, and multiple sets of solar panels are connected and fixed to the shore, which facilitates maintenance and installation as well as the collection and use of electricity. Due to the fluctuation of the water surface, the floating blocks and fixing devices need to withstand a certain amount of shaking and impact.

[0003] A patent with publication number CN113630073A discloses a surface photovoltaic power generation device, including a stabilizing pile. A support frame is installed above the water surface on the stabilizing pile. Photovoltaic power generation units are symmetrically arranged horizontally at both ends inside the support frame. A floating cleaning unit is installed on a sliding track via a limiting slider. A floating plate is installed horizontally below the photovoltaic power generation units. This invention relates to the field of photovoltaic power generation technology. This surface photovoltaic power generation device achieves the goal of gradually flipping the photovoltaic absorption panel towards the direction perpendicular to sunlight, increasing light absorption efficiency and improving photovoltaic power generation efficiency.

[0004] The aforementioned solution currently involves fixing the photovoltaic panels to a fixed frame at a fixed angle and then securing them to a floating block when adjusting the water surface photovoltaic equipment. This allows the panels to tilt towards the sun for better sunlight reception. However, when the photovoltaic panels are installed in different locations, their angle needs to be adjusted according to the sunlight angle to ensure optimal solar energy reception. Currently, the device for adjusting the photovoltaic panel angle can only be adjusted to a fixed angle for photovoltaic power generation and cannot automatically adjust the angle with sunrise and sunset. This results in the photovoltaic panels not being able to adjust their angle with the sun's movement, failing to ensure that the angle of sunlight on the photovoltaic panels is as vertical as possible, and thus failing to maximize solar energy benefits, leading to low power generation efficiency of the photovoltaic equipment.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The self-adjusting water surface photovoltaic power generation device of the present invention adjusts the height of the upward threaded cylinder by rotating the threaded column on one side, so that the connecting frame is tilted to a suitable angle to receive sunlight. The activated cylinder moves the fixed ring, and the fixed ring moves the connecting groove through the connecting ring. The connecting groove rotates the connecting frame through the second limit post to adjust the angle, so that the connecting frame and the photovoltaic panel rotate and tilt to better receive sunlight. The tilt angle of the connecting frame and the photovoltaic panel can be adjusted with the rising and setting of the sun, so that the photovoltaic panel can be tilted as much as possible, so that the sunlight can hit the photovoltaic panel as perpendicularly as possible, optimizing the angle of sunlight hitting the photovoltaic panel, improving the efficiency of the photovoltaic panel in receiving sunlight, and improving the power generation efficiency of the photovoltaic panel.

As the sun rises, sunlight passes through an angle perpendicular to the photovoltaic panel and shines on a concentrator mirror facing away from the rising sun. The sunlight is concentrated onto the light-sensing element by the reflection of the concentrator mirror. At this time, a cylinder is activated to rotate the direction of the falling sunlight, so that the light-sensing element is removed from the sunlight illumination range of the concentrator mirror, thus maintaining the photovoltaic panel perpendicular to the sunlight. This continues until the cylinder can no longer rotate the connecting frame and the photovoltaic panel, extending the time of perpendicular sunlight illumination on the photovoltaic panel as much as possible. When the sun sets, the cylinder will return the connecting frame and the photovoltaic panel to the initial state, and the photovoltaic panels installed on both sides of the river can adjust their angle with the rising sun, so that the photovoltaic panels can generate electricity more efficiently.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: As Figures 1 to 3 As shown in the embodiment of the present invention, a self-regulating water surface photovoltaic power generation device includes a connecting plate 3. A float 1 is provided on the outer side of the connecting plate 3. Two threaded posts 9 are rotatably connected to one side of the connecting plate 3. Each threaded post 9 is fitted with a threaded cylinder 10, and both threaded cylinders 10 are threadedly connected to the threaded posts 9. A rotating frame 4 is rotatably connected to one end of each threaded cylinder 10. A connecting frame 2 is provided on one side of the connecting plate 3. A first limiting groove 13 is opened on one side of the connecting frame 2. A first limiting post 11 is fixedly connected to one side of the rotating frame 4 near the first limiting groove 13. The limiting post 11 is slidably connected to the first limiting groove 13. Cylinders 14 are fixedly connected to both sides of the connecting plate 3. Fixed rings 15 are fixedly connected to the output ends of the two cylinders 14. Adjustment devices are provided on both sides of the connecting frame 2. The adjustment device includes a second limiting groove 19 opened on one side of the connecting frame 2. A second limiting post 18 is slidably connected in the second limiting groove 19. A connecting groove 17 is fixedly connected to one side of the second limiting post 18. The connecting groove 17 is slidably connected to the connecting frame 2. A connecting ring 16 is slidably connected in the connecting groove 17. The connecting ring 16 is movably connected to the fixed ring 15.

[0033] Specifically, currently, when adjusting the water surface photovoltaic equipment, the photovoltaic panel 5 is fixed on the mounting frame to form a fixed tilt angle and fixed on the float 1 so that it can tilt towards the sun to receive sunlight better. However, when the photovoltaic panel 5 is installed in different places, the angle of the photovoltaic panel 5 needs to be adjusted according to the angle of sunlight so that it can receive sunlight better. However, the traditional mounting frame cannot adapt to adjust the angle of the photovoltaic panel 5, resulting in the problem that a mounting frame with a suitable tilt angle needs to be produced every time a new photovoltaic panel 5 is installed, as well as the problem that the mounting frame cannot be reused. Moreover, with the sunrise and sunset, the photovoltaic panel 5 cannot adjust its angle to maximize the benefit of sunlight angle, resulting in the problem of low power generation efficiency of the photovoltaic equipment.

[0034] In this embodiment, when adjusting the photovoltaic panel 5, the photovoltaic panel 5 is placed inside the connecting frame 2. The height of the upward threaded cylinder 10 is adjusted by rotating the threaded post 9 on one side. The threaded cylinder 10 will move the rotating frame 4 and the first limiting post 11 on the same side upward, causing the connecting frame 2 to rotate around the rotating frame 4 on the other side. At this time, the first limiting post 11 will slide in the first limiting groove 13. The first limiting post 11 has a limiting effect in the first limiting groove 13, ensuring that it will not slide out of the first limiting groove 13 while sliding. The height of the two threaded cylinders 10 can be adjusted so that the connecting frame 2 is tilted to a suitable angle to receive sunlight. Then, the adjusted connecting plate 3 and float 1 are placed in water. The buoyancy of the float 1 is sufficient for the entire photovoltaic equipment to generate photovoltaic power. When adjusting the angle of the connecting frame 2 and the photovoltaic panel 5 to better receive sunlight, the cylinder 14 on one side is activated to move the fixing ring 15 downward. The fixing ring 15 moves the connecting groove 17 downward through the connecting ring 16. The connecting groove 17 moves the connecting frame 2 downward through the second limiting post 18. The cylinder 14 descends to the side, activating the other cylinder 14. This cylinder, along with the fixed ring 15, connecting ring 16, connecting groove 17, and second limiting post 18, causes the connecting frame 2 to rise on the other side. This allows the connecting frame 2, along with the photovoltaic panel 5, to rotate and tilt, better receiving sunlight. When the height of the threaded cylinder 10 is adjusted, the connecting frame 2 rotates via the second limiting post 18, causing the connecting groove 17 to rotate. The connecting groove 17 then rotates within the fixed ring 15, carrying the connecting ring 16. When the height of the cylinder 14 is adjusted, the fixed ring 15 moves, causing the connecting ring 16 to slide along the connecting groove 17. The connecting ring 16 can still rotate within the fixed ring 15, and the connecting groove 17 slides within the second limiting groove 19, carrying the second limiting post 18. This allows the tilt angle of the connecting frame 2 and the photovoltaic panel 5 to be adjusted according to the rising and setting of the sun, enabling the photovoltaic panel 5 to tilt as much as possible, ensuring sunlight hits the photovoltaic panel 5 perpendicularly. This optimizes the angle of sunlight hitting the photovoltaic panel 5, improving its efficiency in receiving sunlight and increasing its power generation efficiency.

[0035] like Figure 4As shown, an extension plate 25 is fixed to one side of the connecting frame 2, and multiple light-sensing devices are provided on one side of the extension plate 25. The light-sensing devices include a condenser lens 29 fixed to one side of the extension plate 25, and a light-sensing element 30 is fixed to one side of the extension plate 25 on the condenser lens 29. Two adjacent light-sensing devices are arranged in a mirror image.

[0036] Specifically, the initial state of the connecting frame 2 and photovoltaic panel 5 is when the tilt angle faces the rising sun, and this is the maximum tilt angle. The light-sensing element 30, facing the rising sun, is activated. As the sun rises, sunlight passes through an angle perpendicular to the photovoltaic panel 5 and shines on the concentrator 29, which faces away from the rising sun. The concentrator 29 is a concave concentrator, and the sunlight is concentrated onto the light-sensing element 30 through reflection. At this time, the cylinder 14 is activated to rotate the connecting frame 2 towards the setting sun, causing the light-sensing element 30 to move out of the sunlight's range from the concentrator 29. This maintains the photovoltaic panel 5 perpendicular to the sunlight until the cylinder 14 can no longer rotate the connecting frame 2 and photovoltaic panel 5, thus extending the time the sunlight perpendicularly illuminates the photovoltaic panel 5 as much as possible. After the sun sets, the cylinder 14 returns the connecting frame 2 and photovoltaic panel 5 to their initial state, allowing the photovoltaic panels 5 installed on both banks of the river to adjust their angles with the rising sun, enabling the photovoltaic panels 5 to generate electricity more efficiently.

[0037] like Figure 6 As shown, a motor 20 is fixedly connected to one side of the connecting frame 2, and a threaded rod 21 is fixedly connected to the output end of the motor 20. A sliding box 12 is slidably connected to one side of the connecting frame 2. The sliding box 12 is threadedly connected to the threaded rod 21. A first cleaning plate 36 is slidably connected to one side of the sliding box 12. A first cleaning cotton 37 is fixedly connected to the lower side of the first cleaning plate 36. The first cleaning cotton 37 presses against the surface of the photovoltaic panel 5.

[0038] Specifically, at night, the motor 20 is started to rotate the threaded rod 21, causing the sliding box 12 to slide on the connecting frame 2 with the first cleaning plate 36. The first cleaning plate 36 moves with the first cleaning cotton 37 and cleans the surface of the photovoltaic panel 5, so that the photovoltaic panel 5 can perform photovoltaic power generation work well the next day.

[0039] like Figure 7 As shown, the connecting frame 2 is fixedly connected to a toothed rack 22 on one side of the sliding box 12. A first gear 31 is rotatably connected inside the sliding box 12 and meshes with the toothed rack 22. A second gear 32 is rotatably connected to one side of the sliding box 12. A first bevel gear 33 is fixedly connected to one side of the second gear 32. A second bevel gear 34 is rotatably connected to one side of the sliding box 12 and meshes with the first bevel gear 33. A cam 35 is fixedly connected to one side of the second bevel gear 34 and is used to push the first cleaning plate 36 to slide.

[0040] Specifically, when cleaning the surface of the photovoltaic panel 5 with the first cleaning cotton 37, the sliding box 12 slides on the connecting frame 2, causing the first gear 31 to rotate through the gear rack 22. The rotation of the first gear 31 causes the second gear 32 to rotate with the first bevel gear 33. The rotation of the first bevel gear 33 causes the second bevel gear 34 to rotate with the cam 35. The rotation of the cam 35 pushes the first cleaning plate 36 to better clean the surface of the photovoltaic panel 5.

[0041] like Figure 8 As shown, a connecting block 6 is slidably connected to one side of the connecting frame 2, and a pressing post 38 is fixedly connected to one side of the first cleaning plate 36. The pressing post 38 is slidably connected to the connecting block 6. A second spring 39 is sleeved on one side of the pressing post 38 inside the connecting block 6. One end of the second spring 39 is fixedly connected to the side of the connecting block 6 near the first cleaning plate 36, and the other end of the second spring 39 is fixedly connected to the side of the pressing post 38 away from the first cleaning plate 36.

[0042] Specifically, the second spring 39 is initially in a stretched state and is located on the side of the connecting block 6 near the first cleaning plate 36. When the cam 35 pushes the first cleaning plate 36 to clean the surface of the photovoltaic panel 5 through the first cleaning cotton 37, the first cleaning plate 36 moves within the connecting block 6 with the pressing column 38 and stretches the second spring 39. When the cam 35 stops pushing the first cleaning plate 36, the second spring 39 returns to its initial state, causing the pressing column 38 to slide back to its original position with the first cleaning plate 36, waiting for the cam 35 to push the first cleaning plate 36 again, so that the first cleaning plate 36 moves back and forth with the first cleaning cotton 37 to clean the photovoltaic panel 5.

[0043] like Figure 5 As shown, a second cleaning plate 26 is slidably connected to one side of the extension plate 25, and a plurality of cleaning blocks 27 are fixedly connected to one side of the second cleaning plate 26. The plurality of cleaning blocks 27 are all located between the two condenser lenses 29 and the photosensitive element 30. A second cleaning cotton 28 is fixedly connected to both sides of the plurality of cleaning blocks 27. The second cleaning cotton 28 on both sides of two adjacent cleaning blocks 27 are mirrored. The plurality of second cleaning cotton 28 are used to clean the condenser lenses 29 and the photosensitive element 30 on both sides respectively.

[0044] Specifically, when cleaning the condenser lens 29 and the light sensor 30 at night, the pressure column 38 will push the second cleaning plate 26 to move the cleaning block 27 with the second cleaning cotton 28 to clean the condenser lens 29 and the light sensor 30 on both sides.

[0045] like Figure 4 As shown, two sliding cylinders 24 are fixedly connected to one side of the connecting frame 2. A first spring 23 is sleeved on the outside of each of the two sliding cylinders 24. One end of each of the two first springs 23 is fixedly connected to the second cleaning plate 26, and the other end of each of the two first springs 23 is fixedly connected to the connecting frame 2. One end of each of the two sliding cylinders 24 is fixedly connected to the second cleaning plate 26.

[0046] Specifically, the first spring 23 is initially in a stretched state and the slide cylinder 24 is in a retracted state. When the pressing column 38 pushes the second cleaning plate 26, the pressing column 38 moves the second cleaning plate 26, causing the second cleaning cotton 28 to move and clean the condenser lens 29 and the photosensitive element 30. At this time, the second cleaning plate 26 moves one end of the first spring 23, stretching the first spring 23 and causing the slide cylinder 24 to slide out. Figure 4 As shown, when the pressure column 38 does not push the second cleaning plate 26, the first spring 23 returns to its initial state and moves the second cleaning plate 26 back to the side of the condenser lens 29 and the light sensor 30, so that the second cleaning cotton 28 can move back and forth to clean the condenser lens 29 and the light sensor 30.

[0047] like Figure 4 As shown, a sliding opening 40 is provided on one side of the second cleaning plate 26, and the sliding opening 40 is used for the pressure column 38 to slide through the second cleaning plate 26.

[0048] Specifically, when the condenser lens 29 is in use, the pressing post 38 presses against one side of the second cleaning plate 26, which allows the second cleaning cotton 28 to move back and forth to clean the condenser lens 29 and the photosensitive element 30. When the pressing post 38 moves to the sliding opening 40, the pressing post 38 will pass through the sliding opening 40 and will no longer press against the second cleaning plate 26, stopping the cleaning of the condenser lens 29 and the photosensitive element 30. This saves power and allows the first cleaning plate 36 to smoothly carry the first cleaning cotton 37 for subsequent cleaning.

[0049] Example 2: Figure 9 As shown in Example 1, another embodiment of the present invention is as follows:

[0050] The connecting plate 3 is equipped with multiple conversion devices, including multiple horizontal rotating wheels 7 rotatably connected to one side of the connecting plate 3. The multiple horizontal rotating wheels 7 are used to convert water energy into electrical energy.

[0051] Specifically, when water flow or water waves impact the connecting plate 3, they will pass over the horizontal rotating wheel 7, causing the horizontal rotating wheel 7 to rotate. The kinetic energy of the horizontal rotating wheel 7 is converted into electrical energy for use, and the impact of the water flow is reduced by multiple horizontal rotating wheels 7.

[0052] like Figure 9 As shown, the conversion device also includes multiple vertical rotating wheels 8 rotatably connected to one side of the connecting plate 3, multiple horizontal rotating wheels 7 and vertical rotating wheels 8 are alternately arranged, and the multiple vertical rotating wheels 8 are used to convert water energy into electrical energy.

[0053] Specifically, when water flow or water waves impact the vertical rotating wheel 8, causing it to rotate, the kinetic energy of the vertical rotating wheel 8 is converted into electrical energy. Together with the horizontal rotating wheel 7, this reduces the horizontal and vertical water waves or water flow and converts them into electrical energy for use.

[0054] Working Principle: In this embodiment, when adjusting the photovoltaic panel 5, the photovoltaic panel 5 is placed inside the connecting frame 2. By rotating the threaded column 9 on one side, the height of the upward threaded cylinder 10 is adjusted. The threaded cylinder 10 will move the rotating frame 4 and the first limiting column 11 on the same side upward, causing the connecting frame 2 to rotate around the rotating frame 4 on the other side. At this time, the first limiting column 11 will slide within the first limiting groove 13. The first limiting column 11 has a limiting effect within the first limiting groove 13, ensuring that it will not slide out of the first limiting groove 13 while sliding. Thus, the height of the two threaded cylinders 10 can be adjusted to tilt the connecting frame 2 to a suitable angle to receive sunlight. Then, the adjusted connecting plate 3 and float 1 are placed in water. The buoyancy of the float 1 is sufficient for the entire photovoltaic device to generate photovoltaic power. When adjusting the angle of the connecting frame 2 and the photovoltaic panel 5 to better receive sunlight, the cylinder 14 on one side is activated, moving the fixing ring 15 downward. The fixing ring 15 moves the connecting groove 17 downward through the connecting ring 16. The connecting groove 17 is moved downward through the second limiting column. 18 lowers one side of the connecting frame 2, while activating the other side cylinder 14 via the fixed ring 15, connecting ring 16, connecting groove 17, and second limiting post 18, raising the other side of the connecting frame 2. This allows the connecting frame 2 to rotate and tilt the photovoltaic panel 5 to better receive sunlight. When adjusting the height of the threaded cylinder 10, the connecting frame 2 can rotate via the second limiting post 18, causing the connecting groove 17 to rotate. The connecting groove 17 then rotates within the fixed ring 15, causing the connecting ring 16 to rotate. When adjusting the height of the cylinder 14, the fixed ring 15 moves via the connecting ring 16, causing the connecting groove 17 to slide. The connecting ring 16 can still rotate within the fixed ring 15, and the connecting groove 17 slides within the second limiting groove 19, causing the second limiting post 18 to slide. This allows the tilt angle of the connecting frame 2 and the photovoltaic panel 5 to be adjusted according to the rising and setting of the sun, enabling the photovoltaic panel 5 to tilt as much as possible to receive direct sunlight, optimizing the angle of sunlight hitting the photovoltaic panel 5, improving the efficiency of the photovoltaic panel 5 in receiving sunlight, and improving the power generation efficiency of the photovoltaic panel 5.

[0055] The initial state of the connecting frame 2 and photovoltaic panel 5 is when the tilt angle faces the rising sun, and this is the maximum tilt angle. The light-sensing element 30, facing the rising sun, is activated. As the sun rises, sunlight passes through an angle perpendicular to the photovoltaic panel 5 and shines on the concentrator 29, which faces away from the rising sun. The concentrator 29 is a concave concentrator, and the sunlight is concentrated onto the light-sensing element 30 through reflection. At this time, the cylinder 14 is activated to rotate the connecting frame 2 towards the setting sun, causing the light-sensing element 30 to move out of the sunlight's range from the concentrator 29. This maintains the photovoltaic panel 5 perpendicular to the sunlight until the cylinder 14 can no longer rotate the connecting frame 2 and photovoltaic panel 5, thus extending the time the sunlight perpendicularly illuminates the photovoltaic panel 5 as much as possible. After the sun sets, the cylinder 14 returns the connecting frame 2 and photovoltaic panel 5 to their initial state, allowing the photovoltaic panels 5 installed on both banks of the river to adjust their angles as the sun rises, enabling the photovoltaic panels 5 to generate electricity more efficiently.

[0056] At night, the motor 20 is started, causing the threaded rod 21 to rotate. This causes the sliding box 12 to slide along the connecting frame 2, carrying the first cleaning plate 36. The first cleaning plate 36, carrying the first cleaning cotton 37, moves and cleans the surface of the photovoltaic panel 5, ensuring that the photovoltaic panel 5 can function properly for photovoltaic power generation the next day. While the first cleaning cotton 37 is cleaning the surface of the photovoltaic panel 5, the sliding box 12 slides along the connecting frame 2, causing the first gear 31 to rotate via the gear rack 22. The rotation of the first gear 31 causes the second gear 32 to rotate, carrying the first bevel gear 33. The rotation of the first bevel gear 33 causes the second bevel gear 34 to rotate, carrying the cam 35. The rotation of the cam 35 pushes the first cleaning plate 36 to better clean the surface of the photovoltaic panel 5. The second spring 39 is initially in a stretched state and is in position. On the side of the connecting block 6 near the first cleaning plate 36, when the cam 35 pushes the first cleaning plate 36 to clean the surface of the photovoltaic panel 5 through the first cleaning cotton 37, the first cleaning plate 36 moves within the connecting block 6 with the pressing column 38 and stretches the second spring 39. When the cam 35 releases the push on the first cleaning plate 36, the second spring 39 returns to its initial state, causing the pressing column 38 to slide back to its original position with the first cleaning plate 36, waiting for the cam 35 to push the first cleaning plate 36 again, so that the first cleaning plate 36, with the first cleaning cotton 37, moves back and forth to clean the photovoltaic panel 5. When cleaning the condenser lens 29 and the light sensor 30 at night, the pressing column 38 pushes the second cleaning plate 26, causing the cleaning block 27 to move with the second cleaning cotton 28 to clean the condenser lens 29 and the light sensor 30 on both sides. Cleaning is performed; the first spring 23 is initially in a stretched state and the slide cylinder 24 is in a retracted state. When the pressure column 38 pushes the second cleaning plate 26, the pressure column 38 moves the second cleaning plate 26, causing the second cleaning cotton 28 to move and clean the condenser lens 29 and the photosensitive element 30. At this time, the second cleaning plate 26 moves one end of the first spring 23, stretching the first spring 23 and causing the slide cylinder 24 to slide out. Figure 4As shown, when the pressing column 38 does not push the second cleaning plate 26, the first spring 23 returns to its initial state and moves the second cleaning plate 26 back to the side of the condenser lens 29 and the photosensitive element 30, so that the second cleaning cotton 28 can move back and forth to clean the condenser lens 29 and the photosensitive element 30. When cleaning the condenser lens 29, the pressing column 38 presses against one side of the second cleaning plate 26, so that the second cleaning cotton 28 can move back and forth to clean the condenser lens 29 and the photosensitive element 30. When the pressing column 38 moves to the sliding opening 40, the pressing column 38 will pass through the sliding opening 40 and will no longer press against the second cleaning plate 26, stopping the cleaning of the condenser lens 29 and the photosensitive element 30, saving power so that the first cleaning plate 36 can smoothly carry the first cleaning cotton 37 for subsequent cleaning.

[0057] When water flow or water waves impact the connecting plate 3, they will pass over the horizontal rotating wheel 7, causing the horizontal rotating wheel 7 to rotate. The kinetic energy of the horizontal rotating wheel 7 is converted into electrical energy for use. The impact of the water flow is also reduced by multiple horizontal rotating wheels 7. When water flow or water waves impact the vertical rotating wheel 8, causing the vertical rotating wheel 8 to rotate, the kinetic energy of the vertical rotating wheel 8 is converted into electrical energy. Together with the horizontal rotating wheels 7, the horizontal and vertical water waves or water flow are reduced and converted into electrical energy for use.
