Description

Technical Field

[0001] The present invention relates to the field of clean energy and energy conversion technology, and in particular to a self-cleaning sunlight tracking solar power generation device and a method of using the same. Background Art

[0002] With the rapid development of economy, urbanization level and people's living standard are constantly improving. At the same time, the consumption of earth's energy is also accelerating. The use of fossil energy has brought countless environmental problems, which has led people to constantly seek new clean energy. On this basis, the use of clean energy such as solar energy, wind energy, and hydropower has emerged. At a time when energy reserves are becoming increasingly tight, how to fully develop, utilize, and improve clean energy is worthy of our research and discussion.

[0003] 1. Traditional solar panels are designed in a flat plate style and are directly fixed on the bracket. They lack tracking and rotation mechanisms and cannot automatically adjust the angle according to the dynamic changes in the sun's position. In the morning and afternoon of a day, the sun's rays mostly shine on the solar panels in an oblique manner, causing a large amount of light to be reflected or scattered, and cannot be effectively converted into electrical energy. This non-optimal state of illumination angle directly reduces the power generation efficiency of the solar panels, thereby affecting the economy and sustainability of the entire solar energy system;

[0004] 2. Solar panels are often located in remote or unattended areas, which are often the habitats and activities of birds. Bird excrement adheres to the surface of solar panels, which not only blocks part of the sunlight, but also may cause short circuit risk due to its conductivity, further reducing the photoelectric conversion efficiency. In addition, traditional cleaning methods mostly use direct spraying and flushing, which not only consumes a lot of water resources, but is also more inconvenient in water-scarce areas in the north. Dust accumulation caused by not cleaning for a long time will also significantly affect the power generation efficiency;

[0005] 3. Once a traditional fixed solar panel fails or is damaged, it is necessary to manually remove the fixing bolts for replacement. This process is time-consuming, labor-intensive, and complicated to operate. Especially in large-scale photovoltaic power stations, if the damage of a single solar panel is not handled in time, it may accumulate to a larger area, seriously affecting the overall power generation and system stability.

[0052] In the present invention, a flushing component 51 is connected to the box body 21, and the flushing component 51 includes a water storage chamber 512. The side wall of the box body 21 is provided with a water storage chamber 512, and the water storage chamber 512 is connected to the inner bottom end of the box body 21.

The interior of the filter barrel 511 is filled with activated carbon, so as to facilitate the recycling of water and save water resources.

[0054] Working principle: the solar panel 25 is installed outdoors through the base 1, and the first electric push rod 23 works. When the first electric push rod 23 contracts, it pulls the adjustment rod 22 to move, thereby pushing the box 21 to rotate, and the box 21 drives the fixed ring 24 to change its elevation angle, thereby changing the elevation angle of the solar panel 25, so as to facilitate tracking of sunlight and ensure that the sunlight directly shines on the solar panel 25, thereby ensuring the photoelectric conversion efficiency. In the photovoltaic power generation process, the first motor 27 works to drive the rotating disk 26 to rotate, thereby rotating the solar panel 25 placed inside the rotating disk 26. The power connection end of the solar panel 25 adopts a plug-in method, so that a rotating connector is provided inside the rotating disk 26 to ensure the power transmission of the solar panel 25. When the rotating disk 26 rotates, it drives the paddle 28 to rotate, and the paddle 28 moves along the outer edge of the fixed ring 24, so as to be able to drive away the birds staying on the fixed ring 24 and prevent the birds from staying, thereby effectively preventing the birds from defecating on the solar panel 25 and avoiding affecting the working efficiency of the solar panel 25.

[0055] The bottom storage box 34 contains the solar panel 25. When the second electric push rod 35 is extended, the abutment block 36 abuts against the block 31 on the back of the solar panel 25, thereby limiting the separation of the solar panel 25 and the storage box 34. When the solar panel 25 on the rotating disk 26 rotates normally, the abutment block 36 inside the top storage box 34 extends out. When the solar panel 25 on the rotating disk 26 rotates to the top of the connecting groove 32, the abutment block 36 abuts against the block 31 at the bottom of the solar panel 25, thereby preventing the solar panel 25 from sliding into the connecting groove 32. When the solar panel 25 on the rotating disk 26 is damaged, the damaged solar panel 25 rotates to Above the connecting groove 32, the abutment block 36 contracts, and the damaged solar panel 25 slides into the storage box 34 through the connecting groove 32. The second electric push rod 35 on the storage box 34 extends, and the abutment block 36 extends to abut against the card block 31, limiting the position of the solar panel 25 and limiting the separation of the solar panel 25. The third electric push rod 46 extends, driving the push block 44 to separate from the support rod 45 at one end, and the spring 43 contracts, and the pair of storage boxes 34 approach each other. The third electric push rod 46 continues to extend, and the arc section of the guide groove 47 moves to the slide column 48, thereby guiding the slide column 48 to rotate through the guide groove 47, thereby driving the fixed plate 41 to rotate, and the fixed plate 41 The pair of storage boxes 34 are driven to rotate by the slide bar 42, and the rotating rod 49 can prevent the center of the pair of storage boxes 34 from shifting, so that the pair of storage boxes 34 are exchanged, so that the new solar panel 25 moves to the top, and the third electric push rod 46 continues to extend, and the push block 44 at the other end pushes the pair of support rods 45 at the other end to rotate, so that the pair of storage boxes 34 are separated from each other, and the top storage box 34 will be close to the connecting groove 32, so that the new solar panel 25 is pushed into the rotating disk 26. After the solar panel 25 rotates with the rotating disk 26, the resistance block 36 is reset and used to resist the bottom end of the card block 31 again, so as to maintain the solar panel 25. The normal rotation of the solar panel 25, the abutment block 36 has a certain elasticity, so as to ensure that when the new solar panel 25 rotates with the rotating disk 26, the abutment block 36 can keep the solar panel 25 from falling off and a certain sliding occurs, so as to ensure that the new solar panel 25 enters the fixing ring 24, so as to ensure the normal replacement of the solar panel 25, at the same time, the broken solar panel 25 can slide into the bottom end of the top storage box 34 under gravity, and is limited by the abutment block 36 to avoid sliding, and the solar panel 25 inside the bottom storage box 34 can slide downward under gravity, so as to facilitate the storage of multiple new solar panels 25 at one time;

[0056] When cleaning the solar panel 25, the bottom storage box 34 clamps the clean solar panel 25 through the abutment block 36, and the storage box 34 is rotated to replace the solar panel 25 with stains, and the solar panel 25 with stains fits into the docking groove 53. The water pump 514 works, and the water in the water storage chamber 512 is sucked into the water suction pipe 513 and flows out from the wiping block 54 at one end of the water outlet pipe 515. The second motor 52 works to drive the screw 56 to rotate, drive the moving block 55 to reciprocate, and drive the wiping block 54 to clean the solar panel 25, and the dust is washed away by water. When 54 moves, the slider 573 will move inside the corrugated groove 572, so that the wiping block 54 will swing, thereby increasing the dust cleaning effect, and the sewage will flow into the interior of the box body 21 to form a negative pressure inside the water storage chamber 512, and the sewage inside the box body 21 will be sucked into the water storage chamber 512, filtered through the filter barrel 511 to remove impurities, and the one-way valve 516 can prevent the water inside the water storage chamber 512 from flowing downward into the box body 21, thereby playing a one-way flow role, so that the sewage can be recycled and water resources can be saved. During maintenance, the filter barrel 511 can be pulled out and replaced.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
