[0002] As a renewable and clean energy, solar energy has been given great attention in the development and utilization by many countries. From the initial solar water heaters to the subsequent solar power generation, more and more solar energy utilization technologies have been applied to people's lives. Solar energy has become an indispensable energy source for social development.

[0003] In recent years, photovoltaic panels have been widely used. The use of photovoltaic panels has greatly alleviated the tight pressure on electricity consumption. However, due to the increasingly serious urban industrialization and air pollution, photovoltaic panels are generally set directly outdoors during use, resulting in serious dust accumulation problems on the photovoltaic panels, which greatly affects the photovoltaic panels' absorption and conversion efficiency of sunlight.

[0004] In the prior art, dust on photovoltaic panels is mostly cleaned manually and regularly. In particular, when washing photovoltaic panels with water, a large amount of clean water or clean water mixed with detergent is sprayed on the photovoltaic panels, and then scraped and washed. However, when facing large-scale photovoltaic power generation areas, more manpower is required, and more tools are required for larger photovoltaic panels, resulting in a waste of a lot of manpower and material resources. The manual cleaning method is easy to cause damage to the photovoltaic panels due to the difficulty in controlling the strength, and the cleaning efficiency is low, affecting the power generation efficiency.

[0058] The working principle of the present invention is as follows: when the device is in daily use, the mounting plate 2 is tilted to tilt the photovoltaic panel body 3, and the photovoltaic panel body 3 converts light energy into electrical energy after being exposed to light;

[0059] When it rains, the first motor 10 starts, driving a group of support columns 11 to rotate, and the two groups of support columns 11 are connected by a synchronous belt, the two groups of support columns 11 rotate synchronously, and the inner walls of the two groups of support blocks 12 are respectively threadedly connected with the outer walls of the two groups of support columns 11, so the two groups of support blocks 12 move downward, thereby driving the two groups of protrusions 13 to move downward. Because one end of the two groups of protrusions 13 is movably connected with the inner walls of the two groups of limit grooves 46, the mounting plate 2 moves with the shaft seat 4 as the center of the circle, so that the inclination angle of the mounting plate 2 is reduced, and after the rain falls on the mounting plate 2 and the upper end of the photovoltaic panel body 3, it slides toward the shaft seat 4;

[0060] When the two groups of support columns 11 rotate, one group of support columns 11 is connected to the first drive shaft 14 through a synchronous belt, so the first drive shaft 14 rotates, thereby driving the driving bevel gear 15 to rotate, and the driving bevel gear 15 is meshed and connected with a group of first transmission bevel gears 20, so a group of first transmission bevel gears 20 rotates, thereby driving the first transmission shaft 19 and another group of first transmission bevel gears 20 to rotate, and the other group of transmission bevel gears 20 is meshed and connected with the first linkage bevel gear 18, so the first linkage bevel gear 1 8 rotates, thereby driving a group of first linkage shafts 17 to rotate, and multiple groups of first linkage shafts 17 are connected by synchronous belts, so multiple groups of first linkage shafts 17 rotate synchronously, and the outer walls of multiple groups of first linkage shafts 17 are threadedly connected to the inner wall of the baffle 16, so the baffle 16 is displaced to open the water inlet of the water collection bin 8, and rainwater enters the water collection bin 8 through the water inlet, and part of the rainwater falls on the surface of the mounting plate 2 and the photovoltaic panel body 3, slides toward the shaft seat 4, and then falls to the water inlet of the water collection bin 8, thereby improving the collection efficiency of rainwater;

[0061] When the first drive shaft 14 rotates, the first drive shaft 14 is connected to the second transmission shaft 21 through a synchronous belt, so the second transmission shaft 21 rotates, thereby driving the second transmission bevel gear 22 to rotate, and the second transmission bevel gear 22 is meshed and connected with the second linkage bevel gear 24, so the second linkage bevel gear 24 rotates, thereby driving the second linkage shaft 23 to rotate, because the outer wall of the second linkage shaft 23 is threadedly connected to the inner wall of the first scraper 25, the first scraper 25 is displaced, and the first scraper 25 cleans the surface of the filter plate 9 to prevent branches, fallen leaves and other debris from covering the filter plate 9, thereby improving the use effect of the filter plate 9 and further improving the rainwater collection efficiency;

[0062] When the surface of the photovoltaic panel body 3 is cleaned, the first motor 10 is started, so that the mounting plate 2 moves to a horizontal state, the water collecting plate 38 passes through the reserved groove, the water outlet of the water collecting plate 38 is higher than the level of the photovoltaic panel body 3, and after the fourth linkage bevel gear 44 moves with the mounting plate 2, the fourth linkage bevel gear 44 is meshed and connected with the fourth transmission bevel gear 41;

[0063] When the mounting plate 2 moves to a horizontal state, the first motor 10 is turned off, and the second motor 27 is started to drive the second drive shaft 27 to rotate, and the second drive shaft 27 is connected to a set of limit shafts 35 through a synchronous belt, so a set of limit shafts 35 rotates. Since the two sets of limit shafts 35 are connected through a synchronous belt, the two sets of limit shafts 35 rotate synchronously, and the two sets of limit blocks 42 are displaced, thereby driving the pressure plate 36 to displace;

[0064] When the pressing plate 36 moves downward, the pressing plate 36 squeezes the water pumping box 28, and the two sets of water suction pipes 29 are both provided with one-way valves, so that water will not enter the water collecting bin 8 through the two sets of water suction pipes 29. After the water source inside the water pumping box 28 is pressurized, it enters the water collecting plate 38 through the two sets of water outlet pipes 37, and sprays the water through the water outlet at the upper end of the water collecting plate 38, so that the water is sprayed onto the surface of the photovoltaic panel body 3;

[0065] When the two groups of limit shafts 35 rotate, one group of limit shafts 35 is connected with the movable shaft 39 through a synchronous belt, so the movable shaft 39 rotates, and the movable shaft 39 is connected with the fourth transmission shaft 40 through a synchronous belt, so the fourth transmission shaft 40 rotates, thereby driving the fourth transmission bevel gear 41 to rotate, and then driving the fourth linkage bevel gear 44 to rotate, and then driving a group of fourth linkage shafts 43 to rotate, and the two groups of fourth linkage shafts 43 are connected by synchronous belts, so the two groups of fourth linkage shafts 43 rotate synchronously, and the outer walls of the two groups of fourth linkage shafts 43 are threadedly connected with the inner walls at both ends of the third scraper 45, so the third scraper 45 is displaced, and after water is sprayed onto the surface of the photovoltaic panel body 3, the third scraper 45 pushes the water on the upper end of the photovoltaic panel body 3 to move, and the collected rainwater is used to clean the surface of the photovoltaic panel body 3. If it has not rained for a long time and there is no rainwater in the water collecting bin 8, the maintenance personnel can use the external water pipe to fill the water source into the water collecting bin 8 for use;

[0066] When the pressure plate 36 moves upward, the upper end of the water pumping box 28 moves upward, so that the two groups of water suction pipes 29 absorb the water in the water collecting bin 8 and suck the water in the water collecting bin 8 into the water pumping box 28. The two groups of water outlet pipes 37 are provided with one-way valves inside, so that air will not enter the water pumping box 28 through the two groups of water outlet pipes.

[0067] When the second drive shaft 27 rotates, the second drive shaft 27 is connected to the third transmission shaft 30 through a synchronous belt, so the third transmission shaft 30 rotates, thereby driving the third transmission bevel gear 31 to rotate, and the third transmission bevel gear 31 is meshed and connected with the third linkage bevel gear 33, so the third linkage bevel gear 33 rotates, thereby driving a group of third linkage shafts 32 to rotate, and two groups of third linkage shafts 32 are connected through a synchronous belt, so the two groups of third linkage shafts 32 rotate, thereby driving the two groups of second scrapers 34 to rotate, and the two groups of second scrapers 34 clean the filter screen surfaces at the ends of the two groups of water suction pipes 29 to avoid clogging at the ends of the two groups of water suction pipes 29, thereby improving the water absorption effect of the two groups of water suction pipes 29;

[0068] The present invention arranges a water collecting bin 8, a pumping box 28, a water collecting plate 38 and a third scraper 45. The pumping box 28 extracts the rainwater collected inside the water collecting bin 8 and conducts the rainwater into the water collecting plate 38. The water collecting plate 38 sprays water to the upper end of the photovoltaic panel body 3. The third scraper 45 pushes the water on the upper end of the photovoltaic panel body 3 to move, and the collected rainwater is used to clean the surface of the photovoltaic panel body 3.
