Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a focused solar photovoltaic power generation device. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect to directly convert sunlight into electrical energy. Its core component is the solar cell. When sunlight shines on the surface of the cell, photons excite electrons to transition and generate direct current, which is then converted into alternating current by an inverter for use by the power grid or load.

[0003] Patent publication number CN204633701U relates to a focused solar photovoltaic power generation device, comprising a solar photovoltaic panel, an inverter, and a battery. The solar photovoltaic panel, inverter, and battery are connected sequentially by wires. At least one tracking mirror is provided near the solar photovoltaic panel, and the tracking mirror is mounted on a supporting rotation device connected to a light sensor controller. In this patent, the tracking mirror can rotate to track the light based on collected data. By using the tracking mirror to reflect sunlight onto the solar photovoltaic panel, the light intensity per unit area of ​​the photovoltaic solar panel can be significantly increased, thereby greatly increasing the amount of sunlight absorbed by the solar photovoltaic panel per unit time, thus improving power generation efficiency.

[0004] In the aforementioned patent, sunlight is reflected onto the solar photovoltaic panel through a light-tracking mirror, thereby improving power generation efficiency. However, in severe weather conditions such as rain, snow, or sandstorms, the solar panel may be damaged by external forces, thus affecting the normal operation of the equipment. Therefore, a focusing solar photovoltaic power generation device with adjustable and protective features to adapt to the angle of sunlight is designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a focused solar photovoltaic power generation device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a focusing solar photovoltaic power generation device, comprising a base, a hydraulic column fixedly mounted on the top of the base, a solar panel fixedly mounted on the output end of the hydraulic column, an adjustment device for adjusting the focusing angle of the hydraulic column on the top of the base, the adjustment device comprising a telescopic column fixedly mounted on the top of the base, a fixed sleeve plate fixedly mounted on the free end of the telescopic column, an electric telescopic connecting rod rotatably mounted on the top of the fixed sleeve plate, a protective plate rotatably mounted on the free end of the telescopic column, and a sensor fixedly mounted on the top of the protective plate. A reflector is fixedly installed on the surface of the solar panel, a filter plate is fixedly installed on the inner wall of the protective panel, a water tank is fixedly installed at the bottom of the solar panel, a water pipe is fixedly inserted through the bottom of the protective panel, and a limit rod is fixedly installed at the bottom of the protective panel. This allows for maximum utilization of even low-angle and weak sunlight, enabling the solar panel to maintain high power generation efficiency during more periods, especially when sunlight is weak in the morning and evening. This increases the overall energy efficiency of the photovoltaic power generation system. Furthermore, by adapting to changes in the angle of solar illumination, the solar panel can continuously focus and reflect sunlight, thereby coping with changes in the solar angle, maintaining stable power generation, and thus obtaining more energy output, thereby improving economic returns.

[0007] According to the above technical solution, the electric telescopic linkage is rotatably connected to the surface of the protective plate, the surface of the protective plate is set as an inclined surface, and the sensor is composed of a photosensitive module and a transmission module, which realizes the protection of the solar panel at night or in cloudy or severe weather, avoiding physical damage to the surface of the solar panel during rainy or windy weather, and protecting the reflector and the solar panel from potential damage.

[0008] According to the above technical solution, the water supply pipe is fixedly inserted through the water tank, the surface of the fixed sleeve is provided with a limit groove, and the sensor is electrically connected to the electric telescopic linkage. This effectively utilizes natural precipitation resources and can also reduce dependence on external water sources. Especially in arid or water-scarce areas, this function has significant environmental and economic benefits. Furthermore, the utilization of rainwater as a clean resource also reduces the demand for tap water and helps to save water resources.

[0009] According to the above technical solution, the bottom of the protective plate is provided with a cleaning device for cleaning the absorption surface of the solar panel. The cleaning device includes a fixing block, which is fixedly installed on the bottom of the protective plate. A telescopic connecting plate is rotatably installed on the end of the fixing block away from the protective plate. A sliding block is slidably installed on the surface of the solar panel. A rotating shaft passes through the surface of the sliding block. A scraper is sleeved on the circumferential surface of the rotating shaft. A roller is fixedly installed on the circumferential surface of the rotating shaft. This achieves the cleaning effect on the surface of the solar panel, which can effectively reduce the frequency of manual cleaning, thereby reducing the manpower and material resources invested in the cleaning process, reducing maintenance costs, and improving the photovoltaic effect of the solar panel.

[0010] According to the above technical solution, the end of the sliding block away from the solar panel is rotatably connected to the telescopic connecting plate, and the scraper is slidably connected to the surface of the solar panel to avoid dust accumulation affecting the reduction of solar energy conversion efficiency. Through secondary cleaning, these impurities can be effectively removed, keeping the surface of the solar panel clean, thereby maximizing the received sunlight and improving the photoelectric conversion efficiency of the solar panel.

[0011] According to the above technical solution, the roller contacts the surface of the solar panel, and the circumferential surface of the roller is provided with bristles, which improves the cleaning effect on the surface of the solar panel. The clean photovoltaic panel can better absorb sunlight and avoid the light being blocked or reflected, thereby improving the photoelectric conversion efficiency and further improving the photoelectric conversion efficiency of the solar panel.

[0012] According to the above technical solution, a cooling device for cooling the solar panel is provided at one end of the sliding plate near the telescopic connecting plate. The cooling device includes a telescopic sleeve plate, which is sleeved on the end of the sliding plate near the telescopic connecting plate. A second roller is rotatably mounted on the free end of the telescopic sleeve plate. An arc-shaped plate is fixedly mounted on the bottom of the second roller. A sliding plate is slidably mounted on the inner wall of the water tank. An I-beam plate is slidably mounted on the inner wall of the water tank. A telescopic spring rod is fixedly mounted on the surface of the water tank. A limit plate is slidably mounted on the inner wall of the water tank. A telescopic spring rod is fixedly installed on the inner wall of the tank, and a water supply pipe is fixedly inserted through the bottom of the tank. A water spray ring is fixedly installed on the circumference of the water supply pipe, which further improves the cleaning effect on stubborn stains on the surface of the solar panel and cools the surface of the solar panel. Under prolonged sunlight exposure, the temperature is prone to rise, and the efficiency of the solar panel will decrease as the temperature rises. Water spraying can effectively reduce the temperature of the solar panel, reduce the negative impact of high temperature on photovoltaic modules, reduce the operating temperature of the solar panel, reduce thermal damage, and extend the service life of photovoltaic modules.

[0013] According to the above technical solution, the surface of the second roller is provided with a sliding groove, the telescopic sleeve plate is slidably connected to the inner wall of the sliding groove, and the arc plate is set to a semi-trapezoidal shape; the I-beam plate is fixedly connected to the sliding plate, the free end of the first telescopic spring rod is fixedly connected to the surface of the sliding plate, the free end of the second telescopic spring rod is fixedly connected to the limiting plate, the surface of the water spray ring is provided with a nozzle, and the second roller contacts the arc plate, thereby achieving the effect of quantitatively spraying water to clean the solar panel each time the protective plate is opened and closed, avoiding waste of water resources, ensuring 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.

[0014] This invention provides a focused solar photovoltaic power generation device. It has the following beneficial effects:

[0015] (1) This focused solar photovoltaic power generation device uses sunlight that cannot directly reach the surface of the solar panel to reach the surface of the reflector and reflect the sunlight back to the surface of the solar panel to generate photovoltaic power. The reflected sunlight is stronger, thus maximizing the utilization of the solar panel. Even when the sunlight is weak at low angles, the solar panel can maintain a high power generation efficiency for more periods of time, such as when the sunlight is weak in the morning and evening. This increases the overall energy efficiency of the photovoltaic power generation system. Furthermore, by adapting to changes in the angle of sunlight, the device can continuously focus and reflect sunlight to the solar panel, thereby coping with changes in the angle of sunlight, maintaining stable power generation, and thus obtaining more energy output and improving economic returns.

[0016] (2) When the sensor detects a sudden drop in light intensity, the protective plate will rotate counterclockwise until it closes and protects the solar panel. This protects the solar panel at night or in cloudy or severe weather, preventing physical damage to the surface of the solar panel during rainy or windy weather. The reflector and the protective plate prevent potential damage to the solar panel. After filtration by the filter plate, the filtered rainwater will be transported to the inside of the water tank through the water pipe for storage. This effectively utilizes natural precipitation resources and reduces dependence on external water sources. Furthermore, the use of rainwater as a clean resource reduces the demand for tap water and helps to save water resources.

[0017] (3) This focused solar photovoltaic power generation device uses a scraper to sweep away foreign objects attached to or accumulated on the surface of the solar panel, thereby achieving a cleaning effect on the surface of the solar panel. This can effectively reduce the frequency of manual cleaning, thereby reducing the manpower and material input in the cleaning process, reducing maintenance costs, improving the photovoltaic effect of the solar panel, and avoiding the impact of dust accumulation on the solar energy conversion efficiency. Through secondary cleaning, these impurities can be effectively removed, keeping the surface of the solar panel clean, thereby maximizing the received sunlight and improving the photoelectric conversion efficiency of the solar panel. The roller rotates under the action of the rotating shaft, driving the brush to rotate and sweep the dust on the surface of the solar panel. The foreign objects or dust that the scraper did not clean are swept away again, improving the cleaning effect on the surface of the solar panel. The clean photovoltaic panel can better absorb sunlight, avoiding the light being blocked or reflected, thereby improving the photoelectric conversion efficiency and further improving the photoelectric conversion efficiency of the solar panel.

[0018] (4) In this focused solar photovoltaic power generation device, water inside the water tank is pumped out through the second water supply pipe, and then the second water supply pipe pumps the water into the spray ring and sprays the water onto the surface of the solar panel through the nozzle. This further improves the cleaning effect on stubborn stains on the surface of the solar panel, achieves cooling of the surface of the solar panel, and under long-term sunlight exposure, the temperature is easy to rise, and the efficiency of the solar panel will decrease as the temperature rises. Spraying water to cool down can effectively reduce the temperature of the solar panel, reduce the negative impact of high temperature on the photovoltaic module, reduce the working temperature of the solar panel, reduce thermal damage, and extend the service life of the photovoltaic module.

[0019] (5) When the limiting plate loses its function as an I-beam, the telescopic spring rod deforms and recovers, causing the limiting plate to reset and limit the water inlet of the water supply pipe again until the next operation of the protective plate. This achieves the effect of quantitatively spraying water to clean the solar panel each time the protective plate is opened and closed, avoiding waste of water resources, ensuring 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.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7One embodiment of the present invention is a focusing solar photovoltaic power generation device, comprising a base 1, a hydraulic column 2 fixedly mounted on the top of the base 1, a solar panel 3 fixedly mounted on the output end of the hydraulic column 2, and an adjustment device for adjusting the focusing angle of the hydraulic column 2 provided on the top of the base 1. The adjustment device includes a telescopic column 41, which is fixedly mounted on the top of the base 1. A fixing plate 42 is fixedly mounted on the free end of the telescopic column 41, and an electric telescopic connecting rod 43 is rotatably mounted on the top of the fixing plate 42. A protective plate 44 is rotatably installed on the free end of the telescopic column 41. A sensor 45 is fixedly installed on the top of the protective plate 44. A reflector 46 is fixedly installed on the surface of the protective plate 44. A filter plate 47 is fixedly installed on the inner wall of the protective plate 44. A water tank 48 is fixedly installed at the bottom of the solar panel 3. A water pipe 49 is fixedly inserted through the bottom of the protective plate 44. A limit rod 410 is fixedly installed at the bottom of the protective plate 44. The rotation of the protective plate 44 drives the limit rod 410 to rotate until it is inserted into the limit groove to achieve the fixed and limited effect of the protective plate 44.

[0031] 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 as an inclined plane. The sensor 45 consists of a photosensitive module and a transmission module. The sensor 45 transmits signals to the electric telescopic link 43. The output end of the electric telescopic link 43 moves, driving the protective plate 44 to move.

[0032] A water pipe 49 is fixedly inserted through the water tank 48. A limit groove is opened on the surface of the fixed sleeve plate 42. The sensor 45 is electrically connected to the electric telescopic linkage 43. When the sensor 45 senses that the sunlight has shifted, it will transmit a signal to the electric telescopic linkage 43. The output end of the electric telescopic linkage 43 moves, causing the protective plate 44 to rotate to a suitable angle.

[0033] In this embodiment, during operation: The operator adjusts the height of the solar panel 3 using the hydraulic column 2 until it reaches a suitable height. When the sensor 45 detects a solar intensity signal, because the sensor 45 is electrically connected to the electric telescopic linkage 43, the sensor 45 transmits the signal to the electric telescopic linkage 43. The output end of the electric telescopic linkage 43 moves, causing the protective plate 44 to move. At this time, under the action of the electric telescopic linkage 43, the protective plate 44 rotates clockwise around the free end of the telescopic column 41. At this time, the solar panel 3 is exposed to sunlight to generate photovoltaic power. When the sensor 45 detects a shift in sunlight... The signal is transmitted to the electric telescopic linkage 43. The output end of the electric telescopic linkage 43 moves, causing the protective plate 44 to rotate to a suitable angle. When the protective plate 44 rotates more than 90 degrees under the signal command of the sensor 45, when sunlight cannot directly shine on the surface of the solar panel 3, it will shine on the surface of the reflector 46 and reflect the sunlight back to the surface of the solar panel 3 for photovoltaic power generation. The reflected sunlight is also stronger, maximizing the utilization of even low-angle and weak sunlight, thus enabling the solar panel 3 to maintain high power generation efficiency for more periods, especially when the sunlight is weak in the morning and evening. This increases the overall energy efficiency of the photovoltaic power generation system. By adapting to changes in the angle of solar irradiation, it can continuously focus and reflect sunlight onto the solar panel 3, thus coping with changes in the solar angle, maintaining stable power generation, and obtaining more energy output, thereby improving economic returns. When the sensor 45 senses a sudden drop in light intensity, it will drive the protective plate 44 to rotate counterclockwise until it closes to protect the solar panel 3. This achieves protection for the solar panel 3 at night or in cloudy or inclement weather, preventing physical damage to the surface of the solar panel 3 during rainy or windy weather. The reflector and protective plate 44 protect the solar panel 3 from potential damage. The rotation drives the limiting rod 410 to rotate until it is inserted into the limiting groove, thereby achieving the effect of fixing and limiting the protective plate 44. When the protective plate 44 is closed, in case of rain or snow, rainwater will flow through the inclined surface of its surface to the filter plate 47 and be filtered by the filter plate 47. The filtered rainwater will then be transported to the inside of 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. Furthermore, the use of rainwater as a clean resource also reduces the demand for tap water, which helps to save water resources.

[0034] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a cleaning device for cleaning the absorption surface of the solar panel 3 is provided at the bottom of the protective plate 44. The cleaning device includes a fixing block 51, which is fixedly installed at the bottom of the protective plate 44. A telescopic connecting plate 52 is rotatably installed at the end of the fixing block 51 away from the protective plate 44. A sliding block 53 is slidably installed on the surface of the solar panel 3. A rotating shaft 54 ​​is rotatably passed through the surface of the sliding block 53. A scraper 55 is sleeved on the circumferential surface of the rotating shaft 54. A roller 56 is fixedly installed on the circumferential surface of the rotating shaft 54. A roller 57 is fixedly installed on the circumferential surface of the rotating shaft 54. The rotation of the roller 56 drives the rotating shaft 54 ​​to rotate, and the rotation of the rotating shaft 54 ​​drives the roller 57 to rotate.

[0035] The end of the sliding block 53 away from the solar panel 3 is rotatably connected to the telescopic connecting plate 52. The scraper 55 is slidably connected to the surface of the solar panel 3. The roller 57 rotates under the action of the rotating shaft 54, which drives the brush plate to rotate and clean the dust on the surface of the solar panel 3. The scraper 55 cleans the foreign objects or dust that are not cleaned by the scraper 55.

[0036] Roller 56 contacts the surface of solar panel 3. Brush bristles are provided on the circumference of roller 57. Roller 57 rotates under the action of shaft 54, which drives the brush plate to rotate and clean the dust on the surface of solar panel 3.

[0037] A cooling device for cooling the solar panel 3 is provided at one end of the sliding plate 64 near the telescopic connecting plate 52. The cooling device includes a telescopic sleeve 61, which is sleeved on the end of the sliding plate 64 near the telescopic connecting plate 52. A roller 62 is rotatably installed at the free end of the telescopic sleeve 61. An arc plate 63 is fixedly installed at the bottom of the roller 62. A sliding plate 64 is slidably installed on the inner wall of the water tank 48. An I-beam plate 65 is slidably installed on the inner wall of the water tank 48. A telescopic spring rod 66 is fixedly installed on the surface of the water tank 48. A limit plate 67 is slidably installed on the inner wall of the water tank 48. A telescopic spring rod 68 is fixedly installed on the inner wall of the water tank 48. A water supply pipe 69 is fixedly inserted through the bottom of the water tank 48. A water spray ring 610 is fixedly installed on the circumferential surface of the water supply pipe 69. The water supply pipe 69 pumps water into the water spray ring 610 and then sprays water onto the surface of the solar panel 3 through the nozzle.

[0038] The surface of roller 62 is provided with a sliding groove, and the telescopic sleeve 61 is slidably connected to the inner wall of the sliding groove. The arc plate 63 is set in a semi-trapezoidal shape. The I-beam plate 65 is fixedly connected to the sliding plate 64. The free end of the telescopic spring rod 66 is fixedly connected to the surface of the sliding plate 64. The free end of the telescopic spring rod 68 is fixedly connected to the limiting plate 67. The surface of the spray ring 610 is provided with a nozzle. Roller 62 contacts the arc plate 63. Roller 62 moves downward under the action of the arc plate 63, which drives the free end of the telescopic sleeve 61 to move downward.

[0039] In this embodiment, during operation: 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. Simultaneously, the movement of the fixed block 51 drives the telescopic connecting plate 52 to rotate. The rotation of the telescopic connecting plate 52 drives the sliding block 53 to move closer to the filter plate 47. Simultaneously, the movement of the sliding block 53 drives the rotating shaft 54 ​​to move. The rotating shaft 54, under the action of the sliding block 53, drives the scraper 55 to move. At this time, the scraper 55 sweeps away foreign matter adhering to or accumulated on the surface of the solar panel 3, achieving a cleaning effect on the surface of the solar panel 3. This effectively reduces the frequency of manual cleaning, thereby reducing the manpower and material input during the cleaning process, lowering maintenance costs, improving the photovoltaic effect of the solar panel 3, and preventing dust accumulation from affecting the reduction of solar energy conversion efficiency. Through secondary cleaning, To effectively remove these impurities and keep the surface of the solar panel 3 clean, thereby maximizing the received sunlight and improving the photoelectric conversion efficiency of the solar panel 3, the rotating shaft 54 ​​moves, driving the roller 56 to move. Since the roller 56 is in contact with the solar panel 3, the roller 56 rotates under the action of the solar panel 3. At the same time, the rotation of the roller 56 drives the rotating shaft 54 ​​to rotate, which in turn drives the roller 57 to rotate. The roller 57 rotates under the action of the rotating shaft 54, causing the brush plate to rotate and clean the dust on the surface of the solar panel 3. It also performs a secondary cleaning of foreign objects or dust that the scraper 55 did not clean, improving the cleaning effect on the surface of the solar panel 3. A clean photovoltaic panel can better absorb sunlight and avoid the light being blocked or reflected, thereby improving the photoelectric conversion efficiency and further improving the photoelectric conversion efficiency of the solar panel 3.

[0040] When the rotating shaft 54 ​​moves towards 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 roller 62 to move. Since the roller 62 is in contact with the arc plate 63, the movement of the roller 62, under the action of the arc plate 63, drives the free end of the telescopic sleeve 61 to move downward. Then, the telescopic sleeve 61 continues to move and contact the sliding plate 64, pushing it towards the filter plate 47. The movement of the sliding plate 64 drives the I-beam 65 to move. The limiting plate 67 is moved by contact and pressure. At this time, the limiting plate 67 moves towards the telescopic spring rod 68 under the action of the I-beam plate 65 until it releases the restriction on the water inlet of the water supply pipe 69. At this time, the water inside the water tank 48 is pumped out through the water supply pipe 69. Then, the water supply pipe 69 pumps the water into the spray ring 610 and sprays the water onto the surface of the solar panel 3 through the nozzle. This further improves the cleaning effect on stubborn stains on the surface of the solar panel 3, achieves cooling of the surface of the solar panel 3, and reduces the temperature under long-term sunlight exposure. The temperature rises easily, but the efficiency of the solar panel decreases as the temperature increases. Spraying water to cool down the solar panel 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 near the filter plate 47, the telescopic sleeve 61 moves upward under the action of the roller 62. At this time, the sliding plate 64 is released from the action of the telescopic sleeve 61. At the same time, the telescopic spring rod 66 deforms and restores, causing the sliding plate 64 to reset. When the limiting plate 67 loses the action of the I-beam 65, the telescopic spring rod 68 deforms and restores, causing the limiting plate 67 to reset again, thereby limiting the water inlet of the water pipe 69 until the next operation of the protective plate 44. This achieves the effect of quantitative water spraying to clean the solar panel 3 every time the protective plate 44 opens and closes, 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.
