The four corners of the base frame 1 are provided with mounting grooves 6. A servo motor 7 is fixed inside the mounting groove 6. The rotating shaft of the servo motor 7 passes through the top surface of the mounting groove 6 and is fixed to the bottom surface of the swing arm 8. A rubber scraper 10 is installed on one side of the swing arm 8. A side groove 9 is provided on the bottom surface of one side of the swing arm 8. A rubber scraper 10 is fixed on the top surface of the side groove 9. The height of the rubber scraper 10 is greater than the height of the side groove 9. The rubber scraper 10 is an inverted isosceles trapezoidal plate, and a segmented groove is provided on the bottom surface of the rubber scraper 10. During use, the photovoltaic panel assembly 2 is laid in the groove body of the base frame 1, and the tempered glass plate 4 is glued in the splicing groove 3 to protect the top of the photovoltaic panel assembly 2, and the tempered glass plate 4 is light-transmissive, which is convenient for the base frame 1 to receive light; the base frame 1 is installed on the photovoltaic bracket. When the base frame 1 is installed in an area with more wind and sand or snow, when the surface of the tempered glass plate 4 is covered with wind and sand or snow, the switch of the servo motor 7 is triggered, and the servo motor 7 drives the swing arm 8 to rotate when working. After the servo motor 7 is embedded in the program, it satisfies the swing arm 8 to swing back and forth. During this process, the swing arm 8 drives the rubber scraper 10 to scrape off the wind and sand or snow on the tempered glass plate 4. The frame of the base frame 1 not only realizes the enclosure effect of the photovoltaic panel assembly 2, but also cooperates with the swing arm 8 above to realize the scraping effect of the covering, that is, the photovoltaic panel assembly 2 has two uses.

[0023] A laying groove 11 is provided on the top surface of the swing arm 8, and an LED light strip 12 is fixed on the bottom surface of the laying groove 11; after the LED light strip 12 is installed on the top surface of the swing arm 8, when the LED light strip 12 is lit at night, it not only illuminates the photovoltaic panel laying area, but also the illuminated area serves as a warning to flying objects in the air; at this time, the swing arm 8 not only scrapes off the covering (sand or snow), but also plays a lighting role, and the swing arm 8 has multiple uses.

[0024] An air cavity 13 is provided inside the swing arm 8, and an air pump 15 is installed on the other side of the swing arm 8. An air dispersion port 16 is provided on the surface of the air cavity 13. The air sucked by the air pump 15 is injected into the air cavity 13 and then dispersed through the air dispersion port 16.

The air inside the air cavity 13 is ejected through multiple air diffusion ports 16. The ejected air blows off the dust and leaves on the tempered glass plate 4, thereby cleaning the surface of the tempered glass plate 4; the swing arm 8 not only scrapes off the covering (sand or snow), but also plays a brightening role, and blows off the dust and leaves covering the surface of the tempered glass plate 4. The swing arm 8 has multiple uses.

[0025] A heating wire 19 is installed on the top surface of one side of the swing arm 8. A slot 17 is opened on the top surface of one side of the swing arm 8. The long side length of the slot 17 is smaller than the plate length of the swing arm 8. A heat insulation pad 18 is fixed on the surface of the slot 17. The heat insulation pad 18 is an "L"-shaped plate structure. The heating wire 19 is installed between two parallel side walls of the slot 17. A protective sheet 20 is fixed on the top of one side of the swing arm 8. The protective sheet 20 is an "L"-shaped plate structure. A silicone covering sheet 21 is fixed on the surface of the protective sheet 20. The silicone covering sheet 21 covers the protective sheet 20. A plurality of pressure relief holes 22 are opened on the surfaces of the silicone covering sheet 21 and the protective sheet 20. On snowy days, the switch of the heating wire 19 is triggered, and the heat generated by the heating wire 19 when working is dissipated to the surrounding area through the protective sheet 20 and the silicone covering sheet 21, gradually melting the snow covering the tempered glass plate 4, making it convenient to cooperate with the swinging swing arm 8 to sweep the snow off the tempered glass plate 4; in this way, the swing arm 8 not only achieves the effect of scraping off the covering (wind sand or snow), but also has a brightening effect, and realizes the effect of blowing off the dust and leaves covering the surface of the tempered glass plate 4, and cooperates with the heating wire 19 to melt the snow. The swing arm 8 has multiple uses and rich functions.

[0026] The bottom surface of the reserved groove 5 is slidably connected with a slide 26, and a connecting plate 27 is fixed to the bottom surface of the connecting plate 27. A screw 29 is screwed on the top surface of the connecting plate 27. The screw 29 penetrates the top plate of the connecting plate 27 and is screwed to the bottom surface of the chassis 1. The bottom surface of the reserved groove 5 is provided with a slide 23. The slide 26 and the slide 23 are at the same height. The slide 26 is slidably connected in the slide 23. The surface of the slide 26 is provided with two through-holes 25. The inside of the through-hole 25 is plugged with a guide rod 24. The guide rod 24 is fixed between two parallel side walls of the slide 23. The connecting plate 27 is a "π"-shaped plate structure. A screw hole 28 is provided on the top plate of the connecting plate 27. The screw hole 28 is a "convex"-shaped round hole. There are two screw holes 28, and the two screw holes 28 are symmetrically distributed about the slide 26. The screws 29 and the screw holes 28 correspond one to one. The screws 29 pass through the screw holes 28 and are screwed to the bottom surface of the base frame 1. The end of the screw 29 extends into the bottom groove of the screw hole 28; bolt holes 30 are provided on the two parallel side plates of the connecting plate 27, and the two groups of bolt holes 30 are penetrated by bolts 31; a second notch 32 is provided at the end of the swing arm 8 away from the servo motor 7, and a baffle 33 is fixed on the surface of the reserved slot 5. The height of the baffle 33 is equal to the height of the reserved slot 5, and the height of the swing arm 8 is greater than the height of the reserved slot 5. After the swing arm 8 is retracted into the reserved slot 5, the baffle 33 is inserted into the second notch 32. When installing the base frame 1, it is necessary to adjust the position of the connecting plate 27, that is, to move the connecting plate 27 to pull the slide 26 to slide along the guide rod 24. When the connecting plate 27 slides to the specified position, screw the screw 29 through the top plate of the connecting plate 27 and screw it to the top surface of the base frame 1 to brake the slide 26 and the connecting plate 27. Then, when the base frame 1 is laid on the photovoltaic bracket, the connecting plate 27 is buckled on the cross bar of the photovoltaic bracket, and after the bolt 31 is passed through the bolt hole 30 and the hole on the surface of the cross bar, the bolt 31 is locked to fix the connecting plate 27 between the photovoltaic brackets, and the base frame 1 is laid and fixed on the photovoltaic bracket.

[0027] How to use the solar power generation equipment: Lay the photovoltaic panel assembly 2 in the groove of the base frame 1. Glue the tempered glass plate 4 in the splicing groove 3 to protect the top of the photovoltaic panel assembly 2 and ensure that the tempered glass plate 4 is light-transmissive, so that the base frame 1 can receive light. Move the connecting plate 27 and pull the slide 26 to slide in the slide groove 23 along the guide rod 24. When the connecting plate 27 slides to the specified position, screw the screw 29 so that it passes through the top plate of the connecting plate 27 and is screwed to the bottom surface of the base frame 1. The end of the screw 29 extends into the bottom groove of the screw hole 28 to brake the slide 26 and the connecting plate 27. Lay the base frame 1 on the photovoltaic bracket so that the connecting plate 27 is buckled on the crossbar of the photovoltaic bracket. Pass the bolt 31 through the bolt hole 30 and the hole on the surface of the crossbar and tighten it to fix the connecting plate 27 on the photovoltaic bracket, thus completing the laying and fixing of the base frame 1.

[0028] Cleaning sand or snow: When the chassis 1 is installed in an area with frequent sand or snow, and the surface of the tempered glass plate 4 is covered with sand or snow, the servo motor 7 is triggered. The servo motor 7 drives the swing arm 8 to rotate, and the swing arm 8 swings back and forth, driving the rubber scraper 10 to scrape the sand or snow off the tempered glass plate 4.

[0029] Lighting and warning: At night, the LED light strip 12 lights up to illuminate the area where the photovoltaic panels are laid, and the illuminated area formed serves as a warning to flying objects in the air.

[0030] Cleaning dust or leaves: When the surface of the tempered glass plate 4 is covered with dust or leaves, the air pump 15 is triggered. The air pump 15 sucks in external air and injects it into the air cavity 13. The air inside the air cavity 13 is ejected through multiple air vents 16 to blow off the dust and leaves on the tempered glass plate 4.

[0031] Snow melting: On snowy days, the heating wire 19 is activated. The heat generated by the heating wire 19 is dissipated to the surrounding area through the protective sheet 20 and the silicone cover sheet 21, gradually melting the snow covering the tempered glass plate 4, making it easier for the swinging arm 8 to sweep the snow off the tempered glass plate 4. When the swinging arm 8 is no longer needed, it is retracted into the reserved groove 5, and the blocking piece 33 is inserted into the second notch 32 to serve as a limit.

[0032] Table showing the differences and advantages between the present invention's "solar power generation device" and existing photovoltaic panels:

[0033] The detailed instructions are as follows: Top protection: Existing photovoltaic panels typically lack dedicated top protection, making them susceptible to environmental influences such as wind, sand, and snow, which can damage the panel surface and reduce power generation efficiency. However, the present invention provides effective top protection for the photovoltaic panel assembly 2 by laying a tempered glass sheet 4, enhancing the durability and stability of the equipment.

[0034] Covering material cleaning: When existing photovoltaic panels are covered with heavy covering materials (such as sand, snow, dust, and leaves), they must rely on natural or manual cleaning, which is inefficient and costly. The present invention uses a swing arm 8 to drive a rubber scraper 10 to scrape off sand or snow, and an air pump 15 to blow away dust and leaves through aeration ports 16, achieving automated cleaning. This significantly improves cleaning efficiency and reduces manual intervention.

[0035] Lighting and warning: Existing photovoltaic panels usually do not have a lighting function, which reduces visibility at night and poses a safety hazard. The present invention installs an LED light strip 12 on the top surface of the swing arm 8, which not only achieves lighting but also serves as a warning to flying objects in the air, improving safety.

[0036] Snow-melting function: In snowy conditions, the surface of existing photovoltaic panels is easily covered with snow, resulting in reduced power generation efficiency. In the present invention, a heating wire 19 is installed on one side of the swing arm 8. This, in conjunction with the protective sheet 20 and the silicone cover sheet 21, dissipates heat to gradually melt the snow covering the tempered glass panel 4. This facilitates the swinging of the swing arm 8 to sweep the snow away, thereby improving power generation efficiency.

[0037] Installation and Fixing: Existing photovoltaic panel installation methods are usually relatively simple and inflexible. The present invention connects the slide 26 by sliding in the reserved groove 5 and flexibly fixes it to the photovoltaic bracket through the connecting plate 27 and bolts 31, achieving adjustable installation position and firm fixation.

[0038] One device for multiple uses: The swing arm 8 of the present invention integrates cleaning, lighting, and snow melting into one, thus realizing the multiple uses of the equipment and improving the utilization rate and cost performance of the equipment.

[0039] Design benefits: In summary, the design of the present invention enhances the protective performance of photovoltaic panels, improves cleaning efficiency, enhances safety, adapts to a variety of environments, is flexible to install and has rich functions, thereby reducing maintenance costs, improving power generation efficiency and extending service life.
