Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a high-efficiency photovoltaic power generation device and a method for using the same. Background Art

[0002] Photovoltaic power generation, as a clean and renewable energy utilization method, has received widespread attention and rapid development in recent years. However, in practical applications, the efficiency and life of photovoltaic panels are affected by many factors, among which the angle adjustment, cleaning and maintenance of photovoltaic panels and protective measures are key issues.

[0003] First, due to the rotation of the earth, the relative position between the photovoltaic panel and the sun is constantly changing, resulting in the photovoltaic panel not always being able to maintain a vertical state with the sun, thereby reducing its power generation efficiency. In the prior art, although there are some photovoltaic panel angle adjustment devices, such as the photovoltaic panel fixing device for intelligent buildings that facilitates the adjustment of lighting angles disclosed in announcement number CN110429902B, which realizes the rotation and angle adjustment of the photovoltaic panel through a driving motor and a gear transmission mechanism, the photovoltaic panel angle adjustment method of these devices is relatively simple, and usually can only adjust the angle of the mounting frame and the photovoltaic panel as a whole, but cannot achieve the adjustment of the relative angle between the photovoltaic panel and the mounting frame, which limits the adaptability of the photovoltaic panel under different lighting conditions.

[0004] Secondly, photovoltaic panels are exposed to the outdoor environment for a long time and are easily eroded by external factors such as dust and rain. Especially in windy weather, external sand and gravel can easily damage photovoltaic panels. In addition, after using water to clean the photovoltaic panel, moisture is likely to remain on its surface. If the weather is bad and there is a lot of dust, the residual moisture is likely to adhere to dust again, affecting the cleaning effect and power generation efficiency of the photovoltaic panel. In the prior art, although there are some photovoltaic panel cleaning and protection devices, such as a solar photovoltaic device disclosed in announcement number CN116800191A and a solar photovoltaic panel for photovoltaic power station data collection disclosed in announcement number CN110048670A, these devices either only focus on the cleaning effect and ignore the protective effect, or the combination of protection and cleaning is not tight enough, and it is impossible to effectively prevent the dust from adhering to the surface of the photovoltaic panel again after cleaning.

[0005] Furthermore, the water used in the photovoltaic panel cleaning process is often directly discharged, resulting in a waste of water resources. At the same time, the cleaned water may contain impurities and pollutants, which may cause secondary pollution to the environment if directly discharged. Therefore, how to achieve the recycling of clean water, save water resources, and ensure the cleanliness and effectiveness of the subsequent clean water has become an urgent problem to be solved.

[0024] S2. Optimize the sunlight angle: the electric push rod drives the rack, and the rack meshes with the first gear to drive the connecting plate and the mounting frame to rotate, ensuring that the sunlight vertically illuminates the photovoltaic panel to improve the power generation efficiency;

[0025] S3, automatic cleaning of photovoltaic panels: the electric push rod adjusts the installation frame to the horizontal level, the drive motor drives the screw to move the cleaning device, the water pump sprays clean water, and the cleaning cotton rotates to wipe the surface of the photovoltaic panel to effectively remove dust;

[0026] S4.

During the cleaning process, the water on the photovoltaic panel is filtered through the liquid collection bin, evaporates under the sun and condenses into water droplets at the bottom of the transparent glass, and finally flows back to the liquid storage bin through the conduit for the next cleaning. This design not only saves water resources, but also avoids secondary pollution to the environment caused by the direct discharge of cleaning wastewater.

[0032] 4. The protective structure is stable and reliable, and can withstand severe weather: The protective structure of the present invention ensures that the protective yarn layer can be evenly covered on the photovoltaic panel and effectively resist the influence of external wind through the clever coordination of components such as tension springs, pull ropes and pressure plates. Especially in windy weather, this design can significantly reduce the damage of sand and gravel to the photovoltaic panel and extend its service life.

[0033] 5.

At the same time, the automatic cleaning mechanism can achieve rapid and effective cleaning of the photovoltaic panel surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1 and Figure 2 , a high-efficiency photovoltaic power generation device, which is used in the field of photovoltaic power generation, mainly includes a base 1, a U-shaped shaft 3 is fixed on the top of the base 1, and a mounting frame 2 is rotatably sleeved on the outer wall of the U-shaped shaft 3, and the mounting frame 2 is used to place photovoltaic panels. L-shaped plates 34 are fixed on both sides of the mounting frame 2 for guiding cleaning water. Two connecting plates 5 are arranged above the base 1 for driving the mounting frame 2 to rotate.

[0047] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 Further, the device also includes a first U-shaped frame 11 slidably arranged on the top of the base 1, a liquid storage pipe 17 is fixed to one side of the first U-shaped frame 11, and a plurality of nozzles 41 are fixed to the bottom of the liquid storage pipe 17 for spraying water on the photovoltaic panel. A liquid storage tank 18 is provided in the base 1 for storing clean water.

[0048] Reference Figure 1 , Figure 2 and Figure 6 In addition, the device also includes a second U-shaped frame 26 fixed on the top of the base 1. A protective yarn layer 29 is provided in the second U-shaped frame 26, and the protective yarn layer 29 cooperates with the first U-shaped frame 11 to protect the photovoltaic panel to prevent the external environment from causing damage to the photovoltaic panel.

[0049] Reference Figure 1 , Figure 2 and Figure 4 In order to adjust the angle of the mounting frame 2, the device further includes an adjustment structure. Specifically, the adjustment structure includes a first rotating shaft 4 that rotates on the top of the base 1 through a base, and two connecting plates 5 are respectively fixed at both ends of the first rotating shaft 4. A moving seat 6 is slidably connected to the bottom of the mounting frame 2, and a second rotating shaft 7 is rotatably passed through the moving seat 6, and both ends of the second rotating shaft 7 are respectively fixedly connected to the two connecting plates 5. A first gear 8 is fixedly sleeved on the outer wall of the first rotating shaft 4, and an electric push rod 10 is fixed on the top of the base 1. A rack 9 meshing with the first gear 8 is fixed on the output shaft of the electric push rod 10, and the rack 9 is slidably arranged on the top of the base 1.

[0050] Specifically, the rack 9 is driven to move by the electric push rod 10, and the meshing of the rack 9 and the first gear 8 drives the connecting plate 5 to rotate. The connecting plate 5 drives the moving seat 6 to move through the second rotating shaft 7, thereby controlling the rotation angle of the installation frame 2, so that sunlight can be vertically irradiated on the photovoltaic panel in the installation frame 2, so as to improve the power generation efficiency of the photovoltaic panel.

[0051] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 In order to clean the photovoltaic panel, the device also includes a maintenance structure. Specifically, the maintenance structure includes two rotating shafts 25 rotatably arranged in the first U-shaped frame 11, and the outer walls of the two rotating shafts 25 are fixed with cleaning cotton 15, and the cleaning cotton 15 is used to clean the dust on the top of the photovoltaic panel. A rotating motor 40 is fixed to one side of the first U-shaped frame 11 through a frame, and the output shaft of the rotating motor 40 is fixedly connected to one end of one of the rotating shafts 25. One end of the two rotating shafts 25 extends to one side of the base 1 and is connected through a synchronous wheel and a synchronous belt transmission. A water pump 16 is fixed to the top of the first U-shaped frame 11, and the liquid inlet of the water pump 16 is connected to the liquid storage tank 18 through a first hose, and the liquid outlet of the water pump 16 is connected to the liquid storage pipe 17 through a second hose, which is used to pump the water in the liquid storage tank 18 into the liquid storage pipe 17. When dust accumulates on the photovoltaic panel, the mounting frame 2 remains horizontal, and then the driving motor 13 drives the screw 12 to rotate (the screw 12 is threadedly connected to the first U-shaped frame 11), and the screw 12 drives the first U-shaped frame 11 to move. The water pump 16 pumps the clean water in the liquid storage tank 18 into the liquid storage pipe 17, and sprays it onto the photovoltaic panel through the nozzle 41. When the first U-shaped frame 11 moves, the rotating motor 40 drives the two cleaning cottons 15 to rotate clockwise, and the two cleaning cottons 15 can clean the surface of the photovoltaic panel.

[0052] Reference Figure 1-Figure 3 For the maintenance structure, a liquid collecting bin 19 is provided on the top of the base 1 near the U-shaped shaft 3. The inside of the liquid collecting bin 19 is divided into a liquid collecting tank and a storage tank by a partition 20, and the two are connected. A screen 21 is fixed in the liquid collecting tank for filtering the collected water. A transparent glass 22 is fixed in the storage tank. A gathering tank 23 connected to the storage tank is also provided in the base 1, which cooperates with the transparent glass 22 to collect the clean water condensed on the transparent glass 22. A conduit 24 is fixed to the bottom inner wall of the gathering tank 23, and one end of the conduit 24 is connected to the liquid storage bin 18 for recovering the clean water after condensation.

[0053] Specifically, during the cleaning process, the water on the photovoltaic panel will flow into the two L-shaped plates 34. The bumps on the L-shaped plate 34 will block the water, causing the water to flow along the other end of the L-shaped plate 34 and eventually flow into the liquid collecting bin 19. The screen 21 will filter the water. Under the sun during the day, the water in the liquid collecting bin 19 will evaporate and condense into water droplets at the bottom of the transparent glass 22. These water droplets will flow into the collecting trough 23 along the bottom of the transparent glass 22, and flow back to the liquid storage bin 18 through the conduit 24. In this way, not only water resources are saved, but also it is ensured that the clean water in the liquid storage bin 18 can be effectively used for cleaning the photovoltaic panels in the later stage.

[0054] Reference Figure 2 , Figure 6 , Figure 7 and Figure 8 For the protection structure, the device rotates and penetrates the third rotating shaft 27 on the second U-shaped frame 26, and the outer wall of the third rotating shaft 27 is fixedly sleeved with a winding roller 28. The protective yarn layer 29 is wound around the outer wall of the winding roller 28. A fixed roller 33 is fixed to the side of the first U-shaped frame 11 close to the second U-shaped frame 26 through a base, and one side of the protective yarn layer 29 is fixed to the outer wall of the fixed roller 33. The two sides of the second U-shaped frame 26 are slidably connected to the load-bearing plates 31, and the tops of the two load-bearing plates 31 are fixed to the pull ropes 30, and the tops of the pull ropes 30 are fixed to the outer wall of the third rotating shaft 27. At the same time, the bottoms of the two load-bearing plates 31 are fixed to the tension springs 32, and the bottom ends of the tension springs 32 are fixed to the top of the base 1. The cooperation between the tension springs 32 and the pull ropes 30 enables the third rotating shaft 27 to rotate in the opposite direction, thereby tightening the protective yarn layer 29.

[0055] Specifically, when the screw rod 12 drives the first U-shaped frame 11 to move to the left, the first U-shaped frame 11 will pull the protective yarn layer 29 to one side through the fixed roller 33. At this time, the protective yarn layer 29 can just cover the top of the photovoltaic panel. The cooperation of the tension spring 32 and the pull rope 30 can make the third rotating shaft 27 tighten the protective yarn layer 29 so that it covers the photovoltaic panel evenly to protect the photovoltaic panel.

[0056] Reference Figure 5 , Figure 8 and Fig. 9In addition, the protective structure also includes two pressing plates 35, which are slidably arranged on the bottom inner wall of the corresponding L-shaped plate 34. A plurality of first magnets 37 and second magnets 38 are fixedly embedded on the side where the pressing plate 35 and the L-shaped plate 34 are close to each other. Repulsive force is generated between the first magnet 37 and the second magnet 38, which forms a gap between the first magnet 37 and the pressing plate 35. A trapezoidal plate 36 is fixed on the side where the two pressing plates 35 are close to each other. Two push plates 39 are fixed on the top inner wall of the first U-shaped frame 11, and the push plates 39 are rotatably sleeved on the outer walls of the two rotating shafts 25. The push plates 39 cooperate with the trapezoidal plates 36 to drive the pressing plate 35 to move in the direction of the L-shaped plate 34 and clamp one side of the protective yarn layer 29. It should be noted that the width of the protective yarn layer 29 is greater than the spacing between the two pressing plates 35, but less than the spacing between the two L-shaped plates 34.

[0057] Reference Figure 5 , Figure 8 and Fig. 9 In actual operation, when the distance between the two sides of the protective yarn layer 29 is greater than the distance between the two pressing plates 35, the two sides of the protective yarn layer 29 will fall downward. Therefore, the two sides of the protective yarn layer 29 will be located between the adjacent pressing plates 35 and the inner wall of one side of the L-shaped plate 34. As the first U-shaped frame 11 continues to move, the push plate 39 will cooperate with the trapezoidal plate 36 and drive the pressing plate 35 to move away from the installation frame 2. At this time, the pressing plate 35 and the L-shaped plate 34 will cooperate to clamp the protective yarn layer 29, thereby preventing the protective yarn layer 29 from fluttering due to excessive external wind force.

[0058] Reference Figure 2 and Figure 3 As for the maintenance structure, the top of the two L-shaped plates 34 is fixed with a protrusion on one side close to the first U-shaped frame 11. The main function of these protrusions is to block the clean water from flowing toward the first U-shaped frame 11, ensuring that the clean water can flow smoothly into the liquid collection bin 19. At the same time, the placement angle of the transparent glass 22 is set to between 20° and 30°. Such a design is conducive to draining the condensed water at the bottom of the transparent glass 22 to the collection tank 23, which is convenient for the collection and reuse of the condensed water.

[0059] Reference Figure 2 and Figure 7In the implementation of the protective structure, the top of the base 1 is rotatably connected to the screw 12 through the base, and one end of the screw 12 is threaded through the first U-shaped frame 11. The top of the base 1 is also fixed with a driving motor 13 through a frame, and the output shaft of the driving motor 13 is fixedly connected to one end of the screw 12 through a coupling. In addition, the top of the base 1 is also fixed with a guide rod 14 through the base, and one end of the guide rod 14 slides through the first U-shaped frame 11. When the driving motor 13 is started, it drives the first U-shaped frame 11 to move through the screw 12. This movement can not only clean the photovoltaic panel, but also protect the photovoltaic panel when necessary, and prevent the external environment from damaging the photovoltaic panel by covering it with a protective yarn layer 29.

[0060] Example 2: Reference Fig.10 , improved on the basis of Example 1: Finally, in the angle adjustment mechanism of the photovoltaic panel, the adjustment shaft 42 is rotatably connected in the mounting frame 2, and the outer wall of the adjustment shaft 42 is fixedly sleeved with a placement plate 43, and the top of the placement plate 43 is used to install the photovoltaic panel. One end of the adjustment shaft 42 is rotated to extend to one side of the mounting frame 2 and is fixed with a baffle 44, which is convenient for manual operation. The outer wall of the adjustment shaft 42 is also slidably connected to the second gear 45 through a slide groove and a slider, and an inner gear ring 46 is fixed on one side of the mounting frame 2, and the inner gear ring 46 is meshed with the second gear 45. In addition, a third magnet 47 is fixedly embedded on one side of the mounting frame 2, and an iron layer is fixed on the side of the second gear 45 close to the mounting frame 2. The second gear 45 is limited by the magnetic attraction generated between the iron layer and the third magnet 47 to ensure the stability of the photovoltaic panel after the angle is adjusted. When it is necessary to adjust the direction of the photovoltaic panel so that it receives sunlight at various angles, it is only necessary to pull the second gear 45 outward to release the meshing between the second gear 45 and the inner gear ring 46. Then, the placement plate 43 and the photovoltaic panel are driven to rotate to a suitable position by adjusting the shaft 42, so that the photovoltaic panel can fully receive sunlight and improve the photovoltaic power generation efficiency.

[0061] A method for using a high-efficiency photovoltaic power generation device comprises the following steps:

[0062] S1. Install the photovoltaic panel on the top of the placement plate 43. When the direction of the photovoltaic panel needs to be adjusted so that the photovoltaic panel receives sunlight at various angles, just pull the second gear 45 outward to release the meshing between the second gear 45 and the inner gear ring 46, and then drive the placement plate 43 and the photovoltaic panel to rotate through the adjustment shaft 42, so that the photovoltaic panel can fully receive sunlight.

[0063] S2. In addition, the rack 9 is driven to move by the electric push rod 10, and the meshing of the rack 9 and the first gear 8 drives the connecting plate 5 to rotate, and the connecting plate 5 drives the moving seat 6 to move through the second rotating shaft 7, thereby being able to control the rotation angle of the installation frame 2, so that the sunlight can be vertically irradiated on the photovoltaic panel in the installation frame 2, so as to improve the power generation efficiency of the photovoltaic panel;

[0064] S3. When dust accumulates on the photovoltaic panel, the output shaft of the electric push rod 10 drives the rack 9 to move to the left to keep the mounting frame 2 in a horizontal state, and then the driving motor 13 drives the screw 12 to rotate, and the screw 12 drives the first U-shaped frame 11 to move, and the water pump 16 pumps the clean water in the liquid storage tank 18 into the liquid storage pipe 17 and sprays it onto the photovoltaic panel through the nozzle 41. When the first U-shaped frame 11 moves, the rotating motor 40 drives the two cleaning cottons 15 to rotate clockwise, and the two cleaning cottons 15 can clean the surface of the photovoltaic panel;

[0065] S4. During cleaning, the water on the photovoltaic panel flows into the two L-shaped plates 34. The protrusions on the L-shaped plates 34 block the water, so the water flows along the other end of the L-shaped plate 34 and flows into the liquid collecting bin 19. The screen 21 filters the water. In addition, under the sunlight during the day, the water in the liquid collecting bin 19 evaporates and condenses into water droplets at the bottom of the transparent glass 22. The water droplets flow into the gathering tank 23 along the bottom of the transparent glass 22 and flow back to the liquid storage bin 18 through the conduit 24, which is used to distill and recycle the cleaned water, save water resources, and ensure that the clean water in the liquid storage bin 18 can effectively clean the photovoltaic panel in the later stage;

[0066] S5. When the photovoltaic panel needs to be protected, the screw 12 drives the first U-shaped frame 11 to move to the left, and the first U-shaped frame 11 pulls the protective yarn layer 29 to one side through the fixed roller 33, and the protective yarn layer 29 can just cover the top of the photovoltaic panel, and the cooperation of the tension spring 32 and the pull rope 30 can make the third rotating shaft 27 tighten the protective yarn layer 29, so that the protective yarn layer 29 is evenly covered on the photovoltaic panel, and the two sides of the protective yarn layer 29 extend into the two L-shaped plates 34, and the two sides of the protective yarn layer 29 The distance is greater than the distance between the two pressure plates 35. At this time, the two sides of the protective gauze layer 29 fall downward, so the two sides of the protective gauze layer 29 are respectively located between the adjacent pressure plates 35 and the inner wall of one side of the L-shaped plate 34. As the first U-shaped frame 11 continues to move, the push plate 39 cooperates with the trapezoidal plate 36 and drives the pressure plate 35 to move away from the installation frame 2. At this time, the pressure plate 35 and the L-shaped plate 34 cooperate to clamp the protective gauze layer 29 to prevent the protective gauze layer 29 from fluttering due to excessive external wind.

Those skilled in the art may make any selections according to their needs or convenience.
