[0014] The present invention provides a focused solar photovoltaic power generation device. It has the following beneficial effects: (1) The focusing solar photovoltaic power generation device, through the sunlight that cannot directly shine on the surface of the solar panel, will shine on the surface of the reflector and reflect the sunlight to the surface of the solar panel through the reflector surface to generate photovoltaic power. The reflected sunlight is more intense, so it can be used to the maximum extent, even in low-angle and weak sunlight. As a result, the solar panel can maintain a high power generation efficiency in more time periods, when the sunlight is weak in the morning and evening, thereby increasing the overall energy efficiency of the photovoltaic power generation system.

[0015] (2) When the sensor senses a sudden drop in light intensity, the focusing solar photovoltaic power generation device will drive the protective plate to rotate counterclockwise until the solar panel is closed for protection, thereby protecting the solar panel at night or in cloudy or bad weather, and preventing the surface of the solar panel from being physically damaged during rainy or windy weather.

[0016] (3) The focusing solar photovoltaic power generation device can remove foreign matter attached to or accumulated on the surface of the solar panel by moving the scraper, thereby achieving a cleaning effect on the surface of the solar panel.

The cleaned photovoltaic panel can better absorb sunlight, avoid light being blocked or reflected, and thus improve the photovoltaic conversion efficiency, further improving the photovoltaic conversion efficiency of the solar panel.

[0017] (4) The focusing solar photovoltaic power generation device pumps the water inside the water tank out through the water pipe 2, and then the water pipe 2 pumps the water into the water spray ring and then sprays the water onto the surface of the solar panel through the nozzle, which further improves the cleaning effect of the stubborn stains on the surface of the solar panel and realizes the cooling of the surface of the solar panel. Under long-term sunlight exposure, the temperature is easy to rise, and the efficiency of the solar panel will decrease with the increase in temperature.

[0018] (5) When the limiting plate loses its function as an I-plate, the telescopic spring rod is deformed and restored to drive the limiting plate to reset to limit the second water inlet of the water pipe until the next operation of the protective plate. This achieves the effect of quantitative water spraying and cleaning the solar panel every time the protective plate is opened or closed, avoiding the waste of water resources, ensuring the cooling effect, reducing the frequency of manual maintenance, improving the autonomous operation capability of the solar system, and effectively improving the overall performance and sustainability of the photovoltaic power generation system.

[0023] The electric telescopic link 43 is rotatably connected to the surface of the protective plate 44. The surface of the protective plate 44 is set to be inclined plane 1. The sensor 45 is composed of a photosensitive module and a transmission module. The sensor 45 transmits the signal to the electric telescopic link 43. The output end of the electric telescopic link 43 moves to drive the protective plate 44 to move.

[0024] A water pipe 49 is fixedly passed through the water tank 48, and a limit groove is provided on the surface of the fixed sleeve 42. The sensor 45 is electrically connected to the electric telescopic link 43. When the sensor 45 senses that the sunlight is offset, it will transmit a signal to the electric telescopic link 43. The output end of the electric telescopic link 43 moves to drive the protective plate 44 to rotate to a suitable angle.

[0025] When this embodiment is working: the staff will adjust the height of the solar panel 3 to a suitable height through the hydraulic column 2 according to the situation. When the sensor 45 senses a strong sunlight signal, the sensor 45 is electrically connected to the electric telescopic link 43. At the same time, the sensor 45 transmits the signal to the electric telescopic link 43. The output end of the electric telescopic link 43 moves to drive the protective plate 44 to move. At this time, the protective plate 44 rotates clockwise with the free end rotation point of the telescopic column 41 as the center of the circle under the action of the electric telescopic link 43.

The filtered rainwater will then be transported to the water tank 48 through the water pipe 49 for storage. This effectively utilizes natural precipitation resources and reduces dependence on external water sources, especially in arid or water-scarce areas. This function has significant environmental and economic benefits. The use of rainwater as a clean resource also reduces the demand for tap water, which helps save water resources.

Roller 2 62 is in contact with the arc plate 63, and roller 2 62 moves downward under the action of the arc plate 63, driving the free end of the telescopic sleeve 61 to move downward.

[0031] When the present embodiment is working, when the protective plate 44 rotates clockwise under the action of the electric telescopic connecting rod 43, it drives the fixed block 51 to move, and at the same time, the fixed block 51 moves to drive the telescopic connecting plate 52 to rotate, and the telescopic connecting plate 52 rotates to drive the sliding block 53 to move in the direction close to the filter plate 47. At the same time, the sliding block 53 moves to drive the rotating shaft 54 to move, and the rotating shaft 54 moves under the action of the sliding block 53 to drive the scraper 55 to move. At this time, the scraper 55 moves to sweep the foreign matter attached to or accumulated on the surface of the solar panel 3 out of the surface of the solar panel 3, thereby achieving the cleaning effect of the surface of the solar panel 3, which can effectively reduce the frequency of manual cleaning, thereby reducing the manpower and material investment in the cleaning process, reducing maintenance costs, improving the photovoltaic effect of the solar panel 3, and avoiding the influence of dust accumulation on the decline in solar energy conversion efficiency. Through secondary cleaning, In order to effectively remove these debris and keep the surface of the solar panel 3 clean, thereby maximizing the received sunlight and further improving the photoelectric conversion efficiency of the solar panel 3, at the same time, the movement of the rotating shaft 54 drives the roller 1 56 to move. Because the roller 1 56 is in contact with the solar panel 3, the roller 1 56 moves and rotates under the action of the solar panel 3. At the same time, the rotation of the roller 1 56 drives the rotating shaft 54 to rotate, and the rotation of the rotating shaft 54 drives the roller 57 to rotate. At this time, the roller 57 rotates under the action of the rotating shaft 54 and drives the brush plate to rotate to clean the dust on the surface of the solar panel 3, and performs a second cleaning on the foreign matter or dust that is not cleaned up by the scraper 55, thereby improving the cleaning effect of the surface of the solar panel 3.

[0032] When the rotating shaft 54 moves toward the direction close to the filter plate 47 under the action of the sliding block 53, it drives the telescopic sleeve 61 to move. At the same time, the movement of the telescopic sleeve 61 drives the second roller 62 to move. Because the second roller 62 contacts the arc plate 63, the second roller 62 moves downward under the action of the arc plate 63, driving the free end of the telescopic sleeve 61 to move downward. Then the telescopic sleeve 61 continues to move to contact and push the sliding plate 64 to move toward the direction close to the filter plate 47.

When the temperature of the solar panel is too high, the temperature of the solar panel will rise, and the efficiency of the solar panel will decrease with the increase of temperature. Water spraying for cooling can effectively reduce the temperature of the solar panel, reduce the negative impact of high temperature on the photovoltaic module, reduce the operating temperature of the solar panel, reduce thermal damage, and extend the service life of the photovoltaic module. When the telescopic sleeve 61 moves to the arc surface of the arc plate 63 close to the filter plate 47, the telescopic sleeve 61 moves upward under the action of the roller 2 62. At this time, the sliding plate 64 is separated from the action of the telescopic sleeve 61. At the same time, the deformation of the telescopic elastic rod 1 66 is restored to drive the sliding plate 64 to reset. When the limit plate 67 loses the action of the I-plate 65, the deformation of the telescopic elastic rod 2 68 is restored to drive the limit plate 67 to reset and realize the limit of the water inlet of the water pipe 2 69 again until the next operation of the protective plate 44. This achieves the effect of quantitative water spraying and cleaning of the solar panel 3 every time the protective plate 44 is opened and closed, avoiding waste of water resources, ensuring the cooling effect, reducing the frequency of manual maintenance, improving the autonomous operation capability of the solar system, and effectively improving the overall performance and sustainability of the photovoltaic power generation system.
