It has the advantages of full cleanliness, absolute safety, relative universality, long service life, maintenance-free, sufficient resources and potential economy, and plays an important role in long-term energy strategy.

[0003] A solar photovoltaic panel convenient to adjust is disclosed in Chinese patent CN111769788A announced on October 13, 2020, which comprises a horizontally arranged support mounting plate, a plurality of fixed mounting frames are arranged at equal angles on the lower end edge of the support mounting plate, a fixed mounting cylinder is vertically arranged on each fixed mounting frame, a lifting mounting plate is horizontally arranged above the support mounting plate, a rotating mounting plate is horizontally arranged above the lifting mounting plate, and a transmission mounting cavity is vertically arranged at the middle position of the support mounting plate.

[0004] In the above document, the angle, height and direction of the photovoltaic power generation device can be efficiently and accurately adjusted by controlling the lifting of the stud and cylinder, controlling the steering of the gear and ring, and controlling the swing of the swing telescopic structure arranged at equal angles.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-5 A photovoltaic power generation device with a flexible support structure includes: A photovoltaic panel 1 has heat dissipation holes 2 on its side. A rotating component 4 is mounted on the bottom of the photovoltaic panel 1, and a telescopic support component 3 is mounted below the rotating component 4. There are two support columns 501. Two large gears 503 are rotatably connected to the top of each support column 501. Two output shafts 513 are fixedly connected to the rear of each large gear 503. An external motor is connected to each output shaft 513 to drive the large gears 503 to rotate. Two semi-circular racks 502 mesh with the bottom of each large gear 503. The two semi-circular racks 502 are connected to connecting rods 504. The meshing of the two large gears 503 with the two semi-circular racks 502 drives the two connecting rods 504 to rotate. The two semi-circular racks 502 drive the two air collection boxes 516 to rotate. Connecting rods 504 and semi-circular racks 502 are rotatably connected to the top of each support column 501. Two air collection boxes 516 are fixedly connected to the outside. Filter meshes 510 are fitted to the outside of the two air collection boxes 516. On one side, the filter meshes 510 are arranged in five rows and five columns on the side of one air collection box 516, with twenty-five filter meshes 510 on one side and fifty filter meshes 510 on both sides. All filter meshes 510 are identical in shape and size. This large number of filter meshes 510 can simultaneously handle a large amount of sand and dust, ensuring the cleaned air guarantees stable operation of the device. Two guide ramps 514 are fixedly connected inside the two air collection boxes 516. Two fans 515 are located above the two air collection boxes 516. During operation, the air collection boxes 516 are tilted, allowing wind containing a large amount of sand and dust to rush in. The air collection box 516 allows air to pass through a filter screen 510 to remove sand and dust, leaving the clean air outside. The incoming clean air then flows upwards via a guide ramp 514, simultaneously driving the fans 515 to rotate. The shafts of the two fans 515 pass through both sides of the two air collection boxes 516 and are fixedly connected to four worm gears 507. Four worms 508 mesh with the outer sides of the four worm gears 507. Four double-acting lead screws 505 are fixedly connected below the four worms 508. Eight limiting supports 506 are fixedly connected to the four double-acting lead screws 505. The limiting supports 506 support and fix the double-acting lead screws 505 and also limit the distance to the cleaning brush 509, ensuring it can... The system reciprocates up and down. Four bidirectional lead screws 505 are slidably connected to two cleaning brush plates 509. A fan 515 driven by the wind drives the worm gear 507 to rotate, causing the meshing worm 508 to rotate, which in turn drives the bidirectional lead screws 505 to rotate. This causes the cleaning brush plates 509 to brush the filter mesh 510 up and down, ensuring its filtration effect. The top of the two air collection boxes 516 is connected to the air guide pipe 511, and the air guide pipe 511 is connected to the nozzle 512. The bottom of the nozzle 512 is fixedly connected to the support plate 517, which is fixedly connected to the photovoltaic power generation panel 1. There are seven nozzles 512 on one side and a total of fourteen nozzles 512 on both sides. Each nozzle 512 is the same size and shape.

[0022] In operation, the photovoltaic panel 1 is tilted, and the output shaft 513 rotates the large gear 503, causing the meshing semi-circular rack 502 to rotate. This, in turn, drives the connecting rod 504, which is fixedly connected to it, to rotate. The connecting rod 504 tilts the fixedly connected wind collector 516, reducing wind resistance and minimizing the impact of wind and sand on the wind collector 516. The filter mesh 510 filters the incoming air, leaving the sand and dust outside. The cleaned air flows upward along the guide slope 514. The fan 515 above the wind collector 516 rotates, which in turn drives the worm gear 507 to rotate, causing the meshing worm 508 to rotate. The rotation of the fixed bidirectional lead screw 505 causes the sliding... The connected cleaning brush 509 moves up and down under the action of the limiting support 506, giving the filter mesh 510 a self-cleaning function. This prevents the filter mesh 510 from becoming clogged due to excessive wind and sand, which would affect the normal operation of the downstream components. The air inside the air collection box 516 flows into the air guide duct 511 and is sprayed out through the nozzle 512, forming airflows on the photovoltaic panel 1. This reduces the impact of wind and sand on the photovoltaic panel 1, preventing damage to the photovoltaic panel 1 from long-term exposure to strong winds and sand. It also removes sand and dust from the photovoltaic panel 1, preventing it from being covered by accumulated sand and dust and becoming inoperable, thus enhancing the stability of the photovoltaic panel 1's operation.

[0023] Example 2, please refer to Figures 1-7Four bevel gears 601 are fixedly connected above the four worm gears 508. Two fixing plates 605 are fixedly connected to both sides of the photovoltaic panel 1. Two sliding openings 606 are opened above the two fixing plates 605. Four limiting supports 608 are fixedly connected to the outside of the two fixing plates 605. Two double-acting screw rods 607 are fixedly connected inside the four limiting supports 608. The limiting supports 608 can support and fix the double-acting screw rods 607 and also limit the distance of the double-acting shovel 603, so that it can move left and right. The two bidirectional lead screws 607 reciprocate to the right. Four bevel gears 602 are fixedly connected to the left and right sides of each screw. When the wind collector 516 and the photovoltaic panel 1 tilt, the bevel gears 601 and 602 on the bidirectional lead screws 505 and 607 gradually approach and mesh, causing the bidirectional lead screw 505 to drive the bidirectional lead screw 607 to rotate. Two sliders 604 are slidably connected to the outer walls of the two bidirectional lead screws 607. The inner sides of the two sliders 604 are fixedly connected to... Two sliding shafts 610 are connected to two sliding openings 606. A bidirectional shovel 603 is fixedly connected below the sliding shafts 610. The bidirectional shovel 603 has two front and rear shovels, which can remove solid waste adhering to the photovoltaic panel 1 during back-and-forth movement. A slider 604 can drive the sliding shafts 610 and the bidirectional shovel 603 to reciprocate within the sliding openings 606. The components include two sliders 604, sliding shafts 610, bidirectional shovels 603, four bevel gears 602, two bidirectional lead screws 607, and four limit supports 608. The components are arranged in a mirror-symmetrical pattern. A water pipe 609 is fixedly connected above the outermost nozzle 512. A water pipe 611 is fixedly connected between each nozzle 512. Water enters the nozzle 512 through the water pipe connected to the water pipe 609 to clean the surface of the photovoltaic panel 1. The water pipes 609 and 611 have the same diameter. There are a total of six water pipes 611 connected between each nozzle 512. They are interconnected, have the same diameter, and the same shape. The water pipes 609 and 611 are only on one side.

[0024] In use, based on Embodiment 1, when the air collecting box 516 is tilted, the bevel gear 601 and bevel gear 602, which are fixedly connected to the first and second bidirectional lead screws 505 and 607 respectively, will gradually mesh together, allowing the power of the worm gear 507 to be transmitted to the second bidirectional lead screw 607. The rotation of the second bidirectional lead screw 607 drives the slider 604 to reciprocate along the sliding opening 606 of the outer fixed plate 605, and the sliding shaft 610 connected thereto, carrying the fixedly connected bidirectional shovel plate 603, moves in the photovoltaic power generation... The surface of the photovoltaic panel 1 is cleaned back and forth to remove fixed debris. Water pipe 1 609 and water pipe 2 611 are connected to the nozzle 512 on one side. Water pipe 1 609 is connected to an external water pipe, while water pipe 2 611 is connected to each nozzle 512. When the nozzle 512 on the side connected to water pipe 1 609 and water pipe 2 611 is tilted upward, water is released as needed to clean the photovoltaic panel 1, thereby thoroughly cleaning the photovoltaic panel 1 without wasting manpower and effectively maintaining the working efficiency of the photovoltaic power generation device.

[0025] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, two hydraulic rods 705 are fixedly connected to the top of the two support columns 501, and two hydraulic pipes 704 are fixedly connected to the rear of the two hydraulic rods 705. Two rotating shafts 701 are connected through the interior of the two air collection boxes 516, and four counterweights 702 are fixedly connected to both sides of the two rotating shafts 701. Under the action of their own weight, the counterweights 702 will keep the hydraulic rods 703 vertically downward even when the air collection box 516 is tilted. Four hydraulic rods 703 are fixedly connected to the bottom of the four counterweights 702. The two hydraulic pipes 704 are divided into four hydraulic lines. Pipe 704 is connected to two hydraulic rods 703. Hydraulic rod 705 is squeezed as the connecting rod 504 rotates, causing the liquid in hydraulic rod 705 to be squeezed into hydraulic rod 703 through hydraulic pipe 704. The push rod of hydraulic rod 703 is pushed out to support the air collection box 516. The push rods of the two hydraulic rods 705 are fixed on the two connecting rods 504. The hydraulic blocks of the two hydraulic rods 705 are fixed on the two support columns 501. The two hydraulic rods 705, two hydraulic pipes 704, two hydraulic rods 703, four counterweights 702, and two rotating shafts 701 are distributed in a mirror symmetrical manner.

[0026] In use, based on Embodiment 1 and Embodiment 2, when the large gear 503 rotates, the semi-circular rack 502 meshing with it causes the connecting rod 504 to squeeze the hydraulic rod 705. The liquid in the hydraulic rod 705 is then squeezed through the hydraulic pipe 704 to the hydraulic rods 703 at both ends. When the wind collection box 516 is tilted, the counterweight 702, which is rotatably connected to the rotating shaft 701, will remain vertically downward due to its own weight. The hydraulic rod 703, which is fixedly connected to the counterweight 702, will also remain vertically downward. The hydraulic rod 703, which is being powered, will extend to the ground to support the wind collection box 516, thereby improving the overall wind resistance of the photovoltaic power generation device and enhancing its ability to cope with strong winds and sandstorms.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
