[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figures 1 to 8 As shown, a flexible and adjustable bracket photovoltaic power generation device comprises:

[0038] Photovoltaic panel 1;

[0039] A mounting mechanism 2 is installed at the bottom end of the photovoltaic power generation panel 1, an adjusting mechanism 3 is installed at the bottom end of the mounting mechanism 2, three supporting frames 5 are installed at the bottom end of the adjusting mechanism 3, and a cleaning mechanism 4 is installed between the two ends of the photovoltaic power generation panel 1;

[0040] The adjusting mechanism 3 includes an adjusting shaft 31, a driver 32, a stabilizing frame 33, an adjusting gear 34 and a limiting shaft 35. The driver 32 is installed at one end of the adjusting shaft 31. There are three stabilizing frames 33, three adjusting gears 34 and three limiting shafts 35. The three stabilizing frames 33 are installed on the outer surface of the adjusting shaft 31 through bearings, and the bottom ends of the three stabilizing frames 33 are respectively installed on the top ends of the three supporting frames 5. The three adjusting gears 34 are installed on the outer surface of the adjusting shaft 31, and the three limiting shafts 35 are respectively installed between the inner walls on both sides of the three stabilizing frames 33.

[0041] Depend on Figures 1 to 4 It can be seen that three reinforcing rods 6 are installed between the opposite surfaces of two adjacent supporting frames 5, and the four corners of the bottom end of the photovoltaic panel 1 are installed with a mounting frame 7;

[0042] The outer surfaces of the three limit shafts 35 are all installed with adjustment plates 36, and the top ends of the three adjustment plates 36 are all installed at the bottom end of the mounting mechanism 2. The outer walls of the three adjustment plates 36 are all provided with limit grooves 37, and the outer surfaces of the three adjustment plates 36 are all provided with multiple tooth grooves 38.

[0043] As can be seen from the above, when the photovoltaic panel 1 is successfully assembled and erected in place, the equipment can be stably supported by the trapezoidal support frame 5, and the stability of the bottom of the equipment can be further enhanced by the reinforcement of the reinforcement rod 6. Then the driver 32 can be started. This action will directly drive the adjustment shaft 31 to start rotating, and then drive the three adjustment gears 34 installed thereon to rotate synchronously. In this process, the adjustment gear 34 and the multiple corresponding tooth grooves 38 achieve precise meshing transmission. At the same time, the limit shaft 35 also slides smoothly in the limit groove 37, playing a good guiding and limiting role. This series of precise coordination ensures that the three adjustment plates 36 can rotate stably, thereby flexibly adjusting the angle of the installation box 21. Through this adjustment mechanism, the photovoltaic panel can be accurately and stably adjusted. 1 is adjusted to the best working angle. This design gives the photovoltaic power generation equipment excellent angle adjustment flexibility, enabling it to easily cope with various complex and changeable lighting conditions. No matter how the external environment changes, the photovoltaic power generation panel 1 can always maintain the best working angle to ensure the maximum capture and utilization of solar energy resources. In addition, the photovoltaic power generation equipment has excellent flexible adjustment function and can flexibly adjust the angle according to the lighting conditions of different time periods and seasons to ensure that solar energy can be maximized for power generation at any time. This feature not only significantly improves energy utilization, but also effectively enhances power generation performance and greatly improves power generation efficiency. In general, this innovative design not only improves the overall performance of photovoltaic power generation equipment, but also opens up a new way to more efficiently utilize solar energy resources.

[0044] Specifically, refer to Figures 1 to 4As shown, the adjusting gear 34 is meshed with the corresponding multiple tooth grooves 38, and the adjusting gear 34 is located inside the stabilizing frame 33, the limiting groove 37 is set as an arc structure, the limiting shaft 35 is slidably connected to the limiting groove 37, and the supporting base frame 5 is set as a trapezoidal structure.

[0045] As can be seen from the above, meshing can achieve precise adjustment of the angle. When the adjusting gear 34 rotates, it will mesh with the tooth groove 38 and then drive the adjusting plate 36 to move accordingly, thereby changing the angle of the photovoltaic panel 1, so that the stabilizing frame 33 provides structural support and protection for the adjusting gear 34. The stabilizing frame 33 can protect the adjusting gear 34 from interference from the external environment, while ensuring the smooth operation of the adjusting gear 34, allowing the limiting shaft 35 to slide in the limiting groove 37. The arc structure enables the limiting shaft 35 to maintain a stable moving trajectory during the sliding process, and can also remain stable, while limiting its moving range, ensuring the stability and safety of the structure, and the trapezoidal structure enables the supporting base frame 5 to have better stability and load-bearing capacity, which can ensure the safe operation of the entire photovoltaic power generation device.

[0046] Embodiment 2:

[0047] refer to Figure 5 and Figure 6 As shown, the mounting mechanism 2 includes a mounting box 21, mounting holes 22, forward and reverse screw rods 23, an adjusting handle 24 and a mounting frame 25. The mounting box 21 is mounted on the top of the adjusting mechanism 3. There are eight mounting holes 22, and the eight mounting holes 22 are respectively opened at the four corners of the top end and the four corners of the bottom end of the mounting box 21. The forward and reverse screw rods 23 are mounted between the inner walls on both sides of the mounting box 21 through bearings. The adjusting handle 24 is mounted on one end of the forward and reverse screw rods 23. Two mounting frames 25 are provided, and the two mounting frames 25 are respectively mounted on both sides of the outer surface of the forward and reverse screw rods 23.

[0048] As can be seen from the above, in the process of assembling the photovoltaic panel 1, the preset mounting frame 7 on the photovoltaic panel 1 is firstly accurately inserted into the matching mounting hole 22. This step realizes the preliminary clamping and positioning between the photovoltaic panel 1 and the mounting box 21. Then, the adjusting handle 24 is rotated. This action cleverly drives the rotation of the positive and negative screws 23, thereby driving the two mounting frames 25 installed thereon to move smoothly outward. In this process, the mounting box 21 plays a key limiting role in the mounting frame 25, ensuring that the mounting frame 25 can be accurately and stably inserted into the corresponding mounting frame 7, thereby realizing the firm installation between the photovoltaic panel 1 and the mounting box 21. This design not only makes the installation process of the photovoltaic panel 1 fast and simple, greatly improves the installation efficiency, but also provides great convenience for the subsequent disassembly and replacement work. Whether it is daily maintenance or fault repair, this design can make it easy to deal with without consuming too much time and energy. Therefore, it can be said that this installation method not only improves the disassembly and assembly efficiency, but also lays a solid foundation for the long-term stable operation and later convenient maintenance of the photovoltaic panel 1.

[0049] Preferably, reference Figure 5 and Figure 6 As shown, the mounting hole 22 and the mounting frame 25 are both snap-fitted with the mounting frame 7 , the mounting frame 25 is configured as a U-shaped structure, and the thickness of the mounting frame 25 is consistent with the height of the internal space of the mounting box 21 .

[0050] As can be seen from the above, the mounting frame 7 is snap-fitted into the mounting hole 22, and the mounting bracket 25 is snap-fitted into the mounting frame 7, thereby realizing quick installation and disassembly. The snap-fitting method makes the installation process simpler and faster, and is also convenient for later maintenance and replacement. The U-shaped structure enables the mounting bracket 25 to be firmly snap-fitted into the mounting frame 7, ensuring the stability of the photovoltaic panel 1 during installation, so that the outer surface of the mounting bracket 25 contacts the inner wall of the mounting box 21, so that the mounting box 21 plays a limiting and guiding role on the mounting bracket 25, thereby improving the stability of the mounting bracket 25 during movement.

[0051] Embodiment three:

[0052] refer to Figure 7 and Figure 8 As shown, the cleaning mechanism 4 includes a fixed frame 41, a driving motor 42, a reciprocating screw rod 43 and a moving frame 44. The fixed frame 41, the driving motor 42 and the reciprocating screw rod 43 are each provided with two, the two fixed frames 41 are respectively mounted at both ends of the photovoltaic power generation panel 1, the driving motor 42 is respectively mounted on the outer walls of the two fixed frames 41, the two reciprocating screw rods 43 are respectively mounted between the inner walls of both sides of the two fixed frames 41 through bearings, and the moving frame 44 is mounted between the outer surfaces of the two reciprocating screw rods 43;

[0053] The outer wall of the movable frame 44 is provided with three mounting grooves 45 , and connecting screws 46 are installed inside the three mounting grooves 45 . Locking nuts 47 are installed on the upper and lower outer surfaces of the three connecting screws 46 , and a cleaning wipe 48 is installed between the bottom ends of the three connecting screws 46 .

[0054] As can be seen from the above, when it is necessary to clean the dust on the surface of the photovoltaic panel 1, the drive motor 42 can be started to make the reciprocating screw rod 43 drive the movable frame 44 thereon to reciprocate. At the same time, the fixed frame 41 guides and limits the movable frame 44, and the movable frame 44 drives the cleaning wipe 48 to stably reciprocate back and forth, so that the cleaning wipe 48 can fully clean the dust on the surface of the photovoltaic panel 1, thereby improving the power generation efficiency of the photovoltaic panel 1 and improving the energy utilization rate. When the cleaning wipe 48 needs to be replaced, the locking nut 47 is rotated to cancel the The movable frame 44 is locked, the connecting screw 46 is taken out from the mounting groove 45, the detachable cleaning scraper 48 is replaced, and then the connecting screw 46 on the new cleaning scraper 48 is inserted into the mounting groove 45, and the locking nut 47 is tightened to complete the firm installation of the connecting screw 46 and the movable frame 44. In this way, the new cleaning scraper 48 can fully remove dust and dirt from the photovoltaic panel 1, and the cleaning scraper with the connecting screw 46 can also be replaced to clean the snow on the photovoltaic panel 1, thereby maintaining the efficient power generation capacity of the photovoltaic panel 1.

[0055] Preferably, reference Figure 7 and Figure 8 As shown, the diameter of the connecting screw 46 is consistent with the width of the mounting groove 45 , and the bottom end surface of the cleaning wipe 48 is in contact with the top end surface of the photovoltaic power generation panel 1 .

[0056] From the above, it can be seen that it is necessary to ensure that the connecting screw 46 can be smoothly engaged in the mounting groove 45 to realize the installation connection between the connecting screw 46 and the movable frame 44. The contact can realize the cleaning of the photovoltaic panel 1. The contact between the cleaning wipe 48 and the photovoltaic panel 1 can remove dust and dirt on the surface, thereby maintaining the cleanliness and efficient power generation capacity of the photovoltaic panel 1.

[0057] Application examples:

[0058] This design is applied to various places with complex lighting conditions and the need to efficiently utilize solar energy resources, such as rooftop installations, agricultural greenhouses, remote areas and industrial plants. This design achieves efficient utilization and convenient maintenance of the photovoltaic panel 1 by integrating the adjustment mechanism 3, the installation mechanism 2 and the cleaning mechanism 4. The adjustment mechanism 3 adopts a flexible design and can adjust the angle of the photovoltaic panel 1 in real time according to the actual lighting conditions to ensure that it can maintain the best light receiving state in different time periods. The installation mechanism 2 adopts a modular design to facilitate the rapid disassembly and replacement of the photovoltaic panel 1, thereby improving work efficiency. The cleaning mechanism 4 regularly cleans the surface of the photovoltaic panel 1 to remove dust and dirt to maintain its efficient power generation. Capability. In the above application environment, the present design has demonstrated remarkable effects. Through the flexible adjustment function, the photovoltaic panel 1 can automatically adjust according to the lighting conditions of different time periods and seasons, so as to maximize the use of solar energy resources and improve power generation efficiency. At the same time, the installation mechanism 2 for quick disassembly and replacement makes the maintenance and upgrading of the photovoltaic panel 1 more convenient, reducing the operation and maintenance costs. The setting of the cleaning mechanism 4 ensures the efficient power generation capacity of the photovoltaic panel 1 in the long-term operation and extends its service life. Overall, the present design has significant advantages in improving energy utilization, power generation efficiency and operation and maintenance convenience, and provides a feasible solution for the efficient use of solar energy resources.
