[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1, see Figures 1-6 This embodiment provides a solar-following photovoltaic power generation device, comprising a base 1. An electric turntable 2 is disposed at the upper end of the base 1, serving as a drive device and electrically rotating. This allows the entire photovoltaic device to adjust its position as needed, optimizing the orientation of the solar photovoltaic panels and ensuring they are always aligned with the sun, thereby improving energy efficiency. A mounting frame 3 is fixedly connected to the upper end of the electric turntable 2. A photovoltaic panel body 4 is rotatably connected to the inner wall of the mounting frame 3. A mounting plate 51 is fixedly connected to the lower end of the mounting frame 3. A glass water tank 52 is fixedly connected to the outer wall of the mounting plate 51. A concentrator 53 is disposed at the upper end of the glass water tank 52. This concentrator 53 focuses sunlight, enhancing its intensity and improving illumination efficiency. This concentrator concentrates sunlight into the glass water tank 52, increasing the temperature of the water source. A booster pipe 54 is fixedly connected to one end of the glass water tank 52. A piston 55 is slidably connected to the inner surface of the booster pipe 54. The piston 55 is a key power conversion component in the entire system, converting water vapor pressure into mechanical power. The movement of piston 55 drives connecting rod 56, which in turn drives the subsequent mechanical structure. Connecting rod 56 is fixedly connected to the outer wall of piston 55. The other end of connecting rod 56 flexibly penetrates mounting frame 3 and is fixedly connected to movable plate 57. The upper end of movable plate 57 is hingedly connected to support rod 58, which is hinged to the back of photovoltaic panel body 4. As movable plate 57 moves, support rod 58 changes the angle of the photovoltaic panel. The function of support rod 58 is to ensure that the tilt angle of the photovoltaic panel adjusts with the changes in the sun, always maintaining the optimal lighting angle. The other end of support rod 58 is hinged to the back of photovoltaic panel body 4. A cleaning assembly 7 is mounted on the upper end of electric turntable 2, and a protective assembly 6 is mounted on the outer wall of mounting frame 3.

[0025] Mounting frame 3 has a chute A59 on its inner side. The two ends of movable plate 57 slide along the inner wall of chute A59. A spring A is fixedly connected to the interior of chute A59. The other end of spring A is fixedly connected to movable plate 57. Chute A59 serves as a guide for movable plate 57, ensuring its stable motion path. Spring A automatically returns the PV panel to its initial position after adjustment, ensuring that the panel's angle remains aligned with the sun's changing direction.

[0026] During use, after the sun rises, as the angle of the sun changes and the temperature rises, the water source inside the glass water tank 52 will be heated under the action of the condenser 53. The water is heated to a certain temperature and converted into high-temperature and high-pressure water vapor. The higher the temperature and pressure of the water vapor, the greater the thrust it can generate. The high-temperature and high-pressure water vapor will enter the interior of the boosting pipe 54. In this process, the kinetic energy of the water vapor increases, and the heat energy and pressure originally stored in it will also be converted into kinetic energy, which will push the piston 55 inside the boosting pipe 54 to move outward, thereby driving the moving plate 57 in the inner part of the slide groove A59 through the connecting rod 56. The top of the photovoltaic panel body 4 moves toward the rear end, which will drive the bottom of the support rod 58 to move at the same time, and the photovoltaic panel body 4 on the top of the support rod 58 will rotate accordingly. When the angle of the sun rises higher, the inclination angle of the photovoltaic panel body 4 will be smaller, thereby achieving the effect of following the angle of the sun. When the sun's irradiation angle passes the top of the photovoltaic panel body 4, the electric turntable 2 is started to drive the mounting frame 3 and the photovoltaic panel body 4 to rotate 180 degrees. When the sun's irradiation angle gradually becomes smaller, the water vapor temperature inside the glass water tank 52 will also decrease, and under the action of spring A, the movable plate 57 will be pushed to reset and restore the initial inclination angle.

[0027] Example 2, see Figures 1-6 The protective assembly 6 includes two mounting shafts 61. The outer walls of the two mounting shafts 61 are fixedly sleeved with transmission wheels A62 and B63. The outer walls of the transmission wheels A62 and B63 are wrapped with a transmission belt 64. The end of one side of the mounting shaft 61 away from the mounting frame 3 is fixedly connected to a gear 65. The side of the gear 65 is meshed with a toothed plate 66. The bottom of the toothed plate 66 is fixedly connected to a water collection frame 67. The upper end of the mounting frame 3 is fixedly connected to a fixed plate 612. The outer wall of the fixed plate 612 is fixedly connected to a foldable protective cloth 613. The other end of the protective cloth 613 is fixedly connected to a movable plate 614. The side of the movable plate 614 is fixedly connected to the transmission belt 64 through a connecting block. The bottom of the water collection frame 67 is provided with a water outlet A68. The upper end of the electric turntable 2 is fixedly connected to a spring B69. The upper end of the spring B69 is fixedly connected to the bottom of the water collection frame 67. The spring B69 plays a buffering and recovery role, which helps the water collection frame 67 return to its original position. A sliding groove B610 is provided on the outer wall of the mounting frame 3 , and a sliding block 611 is fixedly connected to the outer wall of the water collecting frame 67 , and the sliding block 611 is slidably connected to the inner wall of the sliding groove B610 .

[0028] During use, when encountering heavy rain, the water collecting frame 67 will collect rainwater. Since the rainfall is large enough, the water outlet speed of the water outlet A68 is lower than the water collecting speed of the water collecting frame 67. Therefore, the water inside the water collecting frame 67 will become more and more, thereby compressing the spring B69 at its bottom and moving downward. When the water collecting frame 67 descends, the slider 611 on its side will slide inside the slide groove B610. Similarly, the tooth plate 66 at the upper end of the water collecting frame 67 will also descend, which will drive the gear 65 on its side to rotate accordingly, and will drive the installation shaft 61 on one side to rotate accordingly. When the installation shaft 61 rotates, the transmission wheel A62 will rotate accordingly. The transmission belt 64 moves, and the transmission wheel B63 and the mounting shaft 61 on the other side will also rotate accordingly, and the transmission belt 64 will pull the movable plate 614 from one end of the mounting frame 3 to the other side, thereby driving the protective cloth 613 to unfold at the same time. When the movable plate 614 moves, it will press the photovoltaic panel body 4 to rotate, and then it will be located at the bottom of the protective cloth 613, thereby achieving a protective effect. When the rain stops, the water outlet A68 will discharge the rainwater inside the water collecting frame 67, and under the action of the spring B69, the water collecting frame 67 will rise, and then the movable plate 614 will retract the protective cloth 613 according to the same principle.

[0029] Example 3, see Figures 1-8 The cleaning component 7 includes a water collecting tank 71, which is opened on the inner side of the mounting frame 3. A water collecting pipe 72 is provided at the bottom of the water collecting tank 71. The upper end of the electric turntable 2 is fixedly connected to a water collecting box 714. The other end of the water collecting pipe 72 is fixedly connected to the water collecting box 714. The upper end of the water collecting box 714 is slidably connected to a moving rod 73. The bottom of the moving rod 73 is fixedly connected to a pressure plate 75. The top of the moving rod 73 is provided with a roller 74. The other end of the water collecting box 714 is fixedly connected to a water pipe 76. The other end of the water pipe 76 is fixedly connected to a water storage tank. Box 77, the water tank 77 is fixedly connected to the top of the photovoltaic panel body 4, and the side of the water tank 77 is fixedly connected to the power water tank 713, and the internal sliding connection of the power water tank 713 is connected to the moving block 78, and the upper and lower ends of the moving block 78 are respectively fixedly connected to the tension spring 79 and the magnetic block 710, and the magnetic block 710 is connected to the cleaning roller 711 through magnetic force. The cleaning roller 711 is used to clean the dust or other debris on the surface of the photovoltaic panel to ensure that the power generation efficiency of the photovoltaic panel will not be affected. The outer wall of the power water tank 713 is provided with a water outlet B712.

[0030] The upper end of the water collection tank 714 is fixedly connected to a spring D715, which is fixedly connected to a limit block 716 at its upper end. Limit block 716 is fixedly mounted on the outer wall of the movable rod 73. One-way valves are installed inside the water collection pipe 72 and the water delivery pipe 76, and an electronic valve is installed between the water storage tank 77 and the power water tank 713.

[0031] During use, when it rains and the photovoltaic panel body 4 has not yet been retracted due to the movable plate 614, the water collection trough 71 will collect rainwater, and then the rainwater will enter the inside of the water collection box 714 through the water collection pipe 72. When the photovoltaic panel body 4 follows the angle of the sun and its inclination changes, the photovoltaic panel body 4 will squeeze the roller 74 at its lower end, so that the moving rod 73 moves to the lower end, then the pressure plate 75 at the bottom of the moving rod 73 will move downward inside the water collection box 714, and then under the action of pressure, the rainwater collected inside the water collection box 714 will enter the inside of the water storage tank 77 through the water delivery pipe 76 (because the one-way valve inside the water collection pipe 72 only allows the rainwater inside the water collection trough 71 to enter the water collection pipe 72, and the one-way valve inside the water delivery pipe 76 only allows the water inside it to enter the water storage tank Box 77), when the photovoltaic panel body 4 needs to be cleaned, the electronic valve between the water tank 77 and the power water tank 713 is opened, and the water inside the water tank 77 will enter the inside of the power water tank 713, and then under the action of gravity, the moving block 78 will move to the lower end inside the power water tank 713, and at the same time, the magnetic block 710 at the bottom will also drop and drive the cleaning roller 711 to drop, thereby achieving the cleaning effect of the photovoltaic panel body 4, and at the same time, the water outlet B712 will gradually discharge the water, then under the action of the tension spring 79, the moving block 78 will drive the magnetic block 710 to reset, and the cleaning roller 711 will also reset accordingly. In addition, when the photovoltaic panel body 4 returns to the initial angle, with the cooperation of the spring D715 and the limit block 716, the moving rod 73 will also reset accordingly.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
