[0002] A floating photovoltaic (PV) support system is a system that mounts PV modules on a floating platform and places them on the water surface to collect solar energy. These systems can be deployed in water bodies such as reservoirs, lakes, and ponds, effectively utilizing surface space to generate clean energy. The design and technology of floating PV supports involve multiple fields, including photovoltaic power generation, floating engineering, structural design, and environmental engineering. A search reveals Chinese Patent Publication No. CN110768618A, which discloses a floating PV support system that can adjust the height, direction, and angle of the installed PV panels according to requirements, improving adaptability and facilitating disassembly and maintenance of the PV panels fixed in the mounting slot, thus improving reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a floating photovoltaic support frame for easy adjustment of direction and angle, comprising a float plate, one end of a connecting column rotatably connected to the inner side of the float plate, the other end of the connecting column being fixedly connected to a fixing plate, a second rotating shaft fixedly connected to one side of the outer wall of the fixing plate, a photovoltaic panel rotatably connected inside the second rotating shaft, the photovoltaic panel being used for collecting and converting light energy, an angle adjustment mechanism fixedly connected to one side of the outer wall of the photovoltaic panel, the angle adjustment mechanism being used to adjust the tilt angle of the photovoltaic panel, and a buoyancy compensation mechanism fixedly connected to the bottom of the outer wall of the float plate, the buoyancy compensation mechanism being used to adjust the buoyancy of the float plate.

[0006] Preferably, the angle adjustment mechanism includes a protective frame, which is fixedly connected to one side of the outer wall of the floating plate. A micro motor is fixedly connected inside the protective frame, and a rocker arm is fixedly connected to the output end of the micro motor. One end of a connecting rod is rotatably connected to one side of the outer wall of the rocker arm. A sliding groove is provided on one side of the outer wall of the photovoltaic panel, and a slider is slidably connected inside the sliding groove. A rotating shaft is fixedly connected to one side of the outer wall of the slider, and a limiting frame is rotatably connected inside the rotating shaft. The other end of the connecting rod passes through the limiting frame.

[0007] Preferably, the direction adjustment mechanism includes a servo motor, which is disposed on one side inside the floating plate. The output end of the servo motor is fixedly connected to one side of the outer wall of the fixed plate. A gear and a telescopic rod are fixedly connected to the outer wall of the output end of the servo motor in sequence. The output end of the servo motor is connected to the limit frame through the telescopic rod.

[0008] Preferably, the buoyancy compensation mechanism includes a long rod rotatably connected to the inner wall of the float plate. A first circular roller and a third driven gear are sequentially fixedly connected to one end of the outer wall of the long rod. A rotating rod is rotatably connected to one side of the outer wall of the float plate. A second circular roller is fixedly connected to the middle of the outer wall of the rotating rod. A long plate is fixedly connected to one end of the outer wall of the rotating rod. A fixing frame is fixedly connected to one side of the inner wall of the float plate. A telescopic plate is fixedly connected to the outer wall of the fixing frame. The fixing frame is connected to the long plate through the telescopic plate.

[0009] Preferably, the limiting frame has a groove inside, and one end of the connecting rod is rotatably connected to a roller, which is slidably connected inside the groove.

[0010] Preferably, a light sensor is fixedly connected to one side of the outer wall of the floating plate, and the light sensor is electrically connected to a micro motor and a servo motor respectively.

[0011] Preferably, one end of a connecting rope is wound around the outer wall of the first roller, and a slot is provided inside the fixing frame. The other end of the connecting rope passes through the slot and is wound around the outer wall of the second roller.

[0012] Preferably, the buoyancy compensation mechanism is symmetrically arranged.

[0013] Preferably, a spring is fixedly connected to one side of the outer wall of the second roller, and the second roller is connected to the float plate through the spring.

[0014] Preferably, the gear one is meshed with two driven gears three on one side, and the two driven gears three on the other side are meshed with each other.

[0015] Working Principle: A micro motor starts, driving a rocker arm to rotate. The connecting rod then rotates in a circular motion. The horizontal motion of the connecting rod is converted into reciprocating sliding within the limiting frame, while the vertical motion drives the limiting frame to move up and down, providing support to the bottom of the photovoltaic panel. This allows the photovoltaic panel to rotate around the second pivot point, thus adjusting its tilt angle. During the reciprocating sliding motion, the rollers convert the sliding motion of the connecting rod into rolling motion within the groove, reducing the contact area between the connecting rod and the outer wall of the limiting frame, reducing friction, and improving the moving efficiency of the limiting frame. The servo motor then starts, driving the fixed plate to rotate, causing the entire photovoltaic panel to rotate around the output end of the servo motor, thus adjusting the orientation of the photovoltaic panel. The adjustment mechanism further limits the movement direction of the limiting frame by the telescopic rod. When the direction adjustment mechanism is activated, the gear meshing transmission drives the two driven gears to rotate. The two circular rollers rotate under the winding of the connecting rope, causing the long plate to rotate in a circle around the rotating rod as a fixed point, so that the telescopic plate extends into a fan shape and covers the water surface. The telescopic plates on both sides extend at the same time, so that the telescopic plate forms a larger coverage area and the buoyancy increases accordingly. Moreover, because the buoyancy compensation mechanism is symmetrically set, when the driven gears on both sides rotate in the same direction, the rotation direction of the rotating rod on both sides is controlled by changing the winding direction of the connecting rope on the outer wall of the two circular rollers. This achieves the same rotation direction of the driven gears on both sides, while driving the telescopic plates on the left and right sides of the float to extend intermittently, so that the buoyancy on the float is more even and the float tilts and sinks.

[0016] The present invention has the following beneficial effects: (1) The present invention, through the relevant settings of the angle adjustment mechanism, enables the tilt angle of the photovoltaic panel to change in real time with the change of light, ensuring the maximum utilization of the photovoltaic panel area and improving the light-to-electricity conversion efficiency; (2) The present invention, through the mutual cooperation of the direction adjustment mechanism and the buoyancy compensation mechanism, realizes the timely buoyancy compensation while changing the orientation of the photovoltaic panel, so that when the gravity on the top of the floating plate is transferred, the buoyancy of the floating plate covering the water surface increases accordingly, offsetting and balancing with the transferred gravity, and avoiding the phenomenon of the floating plate sinking; (3) The present invention, through the symmetrical setting of the buoyancy compensation unit, realizes the intermittent extension of the telescopic plates on both sides, making the buoyancy compensation more accurate.

[0026] The present invention will now be described in detail with reference to the accompanying drawings:

[0027] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a floating photovoltaic support frame that is easy to adjust in direction and angle. It includes a float plate 1, with one end of a connecting column 17 rotatably connected to the inner side of the float plate 1. The other end of the connecting column 17 is fixedly connected to a fixing plate 16. A rotating shaft 15 is fixedly connected to one side of the outer wall of the fixing plate 16. A photovoltaic panel 3 is rotatably connected inside the rotating shaft 15. The photovoltaic panel 3 is used for collecting and converting light energy. An angle adjustment mechanism is fixedly connected to one side of the outer wall of the photovoltaic panel 3. The angle adjustment mechanism is used to adjust the tilt angle of the photovoltaic panel 3. A buoyancy compensation mechanism is fixedly connected to the bottom of the outer wall of the float plate 1. The buoyancy compensation mechanism is used to adjust the buoyancy of the float plate 1.

[0028] The angle adjustment mechanism includes a protective frame 4, which is fixedly connected to one side of the outer wall of the floating plate 1. A micro motor 5 is fixedly connected inside the protective frame 4, and a rocker arm 6 is fixedly connected to the output end of the micro motor 5. One end of a connecting rod 7 is rotatably connected to one side of the outer wall of the rocker arm 6. A groove 9 is provided on one side of the outer wall of the photovoltaic panel 3, and a slider 8 is slidably connected inside the groove 9. A rotating shaft 10 is fixedly connected to one side of the outer wall of the slider 8, and a limit frame 12 is rotatably connected inside the rotating shaft 10. The other end of the connecting rod 7 passes through the limit frame 12. A groove 13 is provided inside the limit frame 12, and a roller 11 is rotatably connected to one end of the connecting rod 7. The roller 11 is slidably connected inside the groove 13. The micro motor 5 starts and drives the rocker arm 6 to rotate. The connecting rod 7 moves in a circular motion as the rocker arm 6 rotates. The horizontal motion of the connecting rod 7 is converted into the reciprocating sliding of the connecting rod 7 inside the limiting frame 12. The vertical motion of the connecting rod 7 is converted into the up and down movement of the limiting frame 12, providing support to the bottom of the photovoltaic panel 3, so that the photovoltaic panel 3 can rotate with the rotating shaft 15 as a fixed point, thereby completing the adjustment of the tilt angle of the photovoltaic panel 3. When the connecting rod 7 reciprocates, the roller 11 converts the sliding motion of the connecting rod 7 into its own rolling motion in the groove 13, reducing the contact area between the connecting rod 7 and the outer wall of the limiting frame 12, reducing the generation of friction, and improving the moving efficiency of the limiting frame 12.

[0029] The direction adjustment mechanism includes a servo motor 18, which is located inside the floating plate 1. The output end of the servo motor 18 is fixedly connected to the outer wall of the fixed plate 16. A gear 19 and a telescopic rod 14 are fixedly connected to the outer wall of the output end of the servo motor 18 in sequence. The output end of the servo motor 18 is connected to the limit frame 12 through the telescopic rod 14.

[0030] Specifically, the servo motor 18 starts and drives the fixed plate 16 to rotate, so that the photovoltaic panel 3 rotates around the output end of the servo motor 18 as a fixed point, thereby completing the adjustment of the direction of the photovoltaic panel 3. At the same time, the telescopic rod 14 further limits the movement direction of the limiting frame 12, so that the limiting frame 12 can only move in the direction perpendicular to the tangent of the outer wall of the servo motor 18, preventing the connecting rod 7 from falling out of the limiting frame 12.

[0031] The buoyancy compensation mechanism includes a long rod 24, which is rotatably connected to the inner wall of the float 1. A circular roller 20 and a driven gear 23 are sequentially fixedly connected to one end of the outer wall of the long rod 24. A rotating rod 25 is rotatably connected to one side of the outer wall of the float 1. A circular roller 27 is fixedly connected to the middle of the outer wall of the rotating rod 25. A long plate 26 is fixedly connected to one end of the outer wall of the rotating rod 25. A fixing frame 30 is fixedly connected to one side of the inner wall of the float 1. A telescopic plate 29 is fixedly connected to the outer wall of the fixing frame 30. The fixing frame 30 is connected to the long plate 26 via the telescopic plate 29. The buoyancy compensation mechanism is symmetrically arranged. Gear 19 meshes with two driven gears 23 on one side, and the two driven gears 23 on the other side mesh with each other. One end of a connecting rope 21 is wound around the outer wall of the circular roller 20. A slot 22 is provided inside the fixing frame 30, and the other end of the connecting rope 21 passes through the slot 22. 2. The roller 27 is wound up on the outer wall of the roller 27. Specifically, when the direction adjustment mechanism is started, the gear 19 meshes and drives the two driven gears 23 to rotate. The roller 27 rotates under the winding of the connecting rope 21, which drives the long plate 26 to rotate around the rotating rod 25 as a fixed point. This causes the telescopic plate 29 to extend into a fan shape and cover the water surface. The telescopic plates 29 on both sides extend at the same time, making the telescopic plate 29 cover a larger area and increasing the buoyancy. Since the buoyancy compensation mechanism is symmetrically set, when the driven gears 23 on both sides turn in the same direction, the rotation direction of the rotating rods 25 on both sides is controlled by changing the winding direction of the connecting rope 21 on the outer wall of the roller 27 on both sides. This achieves the same rotation direction of the driven gears 23 on both sides, while driving the telescopic plates 29 on the left and right sides of the float 1 to extend intermittently, making the buoyancy of the float 1 more uniform and preventing the float 1 from tilting and sinking.

[0032] A light sensor 2 is fixedly connected to one side of the outer wall of the float 1. The light sensor 2 is electrically connected to the micro motor 5 and the servo motor 18 respectively. Specifically, the light sensor 2 is a BH1750 model. The light sensor 2 can sense changes in external light, thereby activating the angle adjustment mechanism, the direction adjustment mechanism, and the buoyancy compensation mechanism by respectively activating the micro motor 5 and the servo motor 18.

[0033] A spring 28 is fixedly connected to one side of the outer wall of the second circular roller 27. The second circular roller 27 is connected to the float plate 1 through the spring 28. Specifically, the second circular roller 27 rotates under the winding of the connecting rope 21, which drives the long plate 26 to rotate in a circle with the rotating rod 25 as the fixed point, so that the telescopic plate 29 extends into a fan shape and covers the water surface. The telescopic plates 29 on both sides extend at the same time, so that the telescopic plates 29 form a larger coverage area and the buoyancy increases accordingly. The spring 28 undergoes elastic deformation as the rotating rod 25 rotates. When the direction of the photovoltaic panel 3 changes again with the direction adjustment mechanism, the spring 28 returns to its original shape, which accelerates the recovery rotation of the rotating rod 25 and improves the contraction efficiency of the telescopic plate 29 on one side.
