Solar panels are the core components of photovoltaic power generation devices. They are made up of several thin photovoltaic cells connected together.

Photovoltaic power generation devices use solar energy to generate electricity, with no emissions or pollution, and are a green energy source.

[0003] After searching, the Chinese patent with the announcement number CN221283112U provides a photovoltaic panel frame that is easy to adjust the angle.

[0025] Beneficial effects of the present invention:

[0026] 1. Plug the T-shaped blocks of two adjacent mounting frames into the T-shaped slots, connect multiple mounting frames, and then install the mounting frame on the top surface of the tripod through the first bolt, and then install the corresponding photovoltaic panel body on the appropriate mounting frame through the hinge axis. Repeat the above steps to facilitate the installation of multiple photovoltaic panel bodies to form a complete photovoltaic power generation array, which is convenient for increasing or reducing the number of photovoltaic panel bodies to meet the power generation needs of different scales, facilitate the assembly, disassembly and maintenance of the photovoltaic panel body, improve the convenience and flexibility of use, and reduce the operating cost.

[0027] 2. The output shaft of the second servo motor drives the first screw located in the middle to rotate, and at the same time, the traction wheel rotates through the friction transmission of the belt and the pulleys on both sides, so that the first screw rotates synchronously, and the first screw pushes the push block to slide inside the protective block, and the push block drives the slide and the pulley to move synchronously, and the pulley slides with the inner wall of the C-shaped block on the bottom surface of the photovoltaic panel body, so that the push block moves and drives the photovoltaic panel body to rotate around the hinge axis, thereby changing its inclination angle, facilitating the adjustment of the photovoltaic panel body to maintain the best angle with the sun, improving the power generation efficiency, realizing the rapid and accurate adjustment of the inclination angle of the photovoltaic panel, and ensuring the stability of the photovoltaic panel body during the adjustment process.

[0028] 3. After the pulley is separated from the C-shaped block, the push block is moved to drive the card block to move downward, so that the card block slides along the Z-shaped block through the through groove and compresses the spring, thereby realizing unlocking, and the pulley and the stud can be removed from the slide by turning the rotating wheel to separate them, which is convenient for replacement and installation. After replacement, the rotating wheel is threadedly connected to the stud to fix the pulley, and the card block is reset under the elastic force of the spring, and the slide is locked again, ensuring the stability of the photovoltaic panel body, reducing the movement or falling off of the pulley, ensuring the firmness and reliability of the pulley during use, ensuring the stability and power generation efficiency of the photovoltaic panel body, simplifying the process of replacing the pulley, and reducing maintenance costs.

[0029] 4. The output shaft of the first servo motor drives the rotating rod to rotate, drives the spiral teeth of the worm to rotate, and makes the spiral teeth of the worm meshing and transmitting to the worm wheel, so that the worm wheel drives the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw makes the two adjusting blocks move on the lead screw, thereby driving the round rod and the fixed block to move. Since the connecting rod connects the circular ring block with the fixed block, the connecting rod pushes the circular ring block to rotate and drives the bracket to rotate, so that the bracket drives the support member and the rotating shaft to rotate, and the rotating shaft rotates along the base. The entire device can be conveniently installed in a suitable use position through the base. At this time, the support member drives the tripod to rotate, which is convenient for rotating the photovoltaic panel body installed on the tripod to a suitable angle. The flexible adjustment of the rotation angle of the photovoltaic panel body adapts to the changes in the position of the sun at different times and seasons, ensures that the photovoltaic panel is always facing the sun, maximizes the power generation efficiency, reduces the floor space, and facilitates the installation and maintenance of the equipment.

[0030] 5. Two adjacent rotating rods are connected by inserting blocks and slots and fixed by connecting bolts, so that one of the rotating rods rotates while driving the connected rotating rod to rotate, which is convenient for rotating multiple rotating rods at the same horizontal position, and one of the T-blocks located at the outer end slides with the other T-slot located at the outer end, thereby improving the stability of multiple photovoltaic panels during rotation, facilitating the simultaneous rotation of photovoltaic panels installed on multiple tripods, so that multiple rotating rods at the same horizontal position rotate at the same time and at the same angle, ensuring that multiple photovoltaic panels installed on the tripod are synchronously adjusted to the best orientation, maintaining the smooth rotation of the photovoltaic panel body, reducing the number and complexity of required components, and reducing installation and maintenance costs, while reducing the additional costs incurred by adjusting the angle of each photovoltaic panel body individually.

[0031] 6. Through the meshing action of the travel gear and the rack on the travel motor, the column and the entire cleaning assembly are moved to the appropriate position along the slide rail. Through the drive of the third servo motor and the threaded connection of the lifting block and the second screw, the height of the lifting block and the cleaning roller is adjusted to the appropriate position. Then, the rotary electric cylinder is started to drive the cleaning roller and the cleaning tube to the appropriate angle through the rotating table, so that the cleaning roller is in friction contact with the top surface of the photovoltaic panel body, and the cleaning tube is parallel to the photovoltaic panel body with a gap, which ensures the pertinence and efficiency of the cleaning work, improves the thoroughness and uniformity of the cleaning, ensures the cleaning effect, and reduces the damage to the photovoltaic panel body.

[0032] 7. The external air is sucked in by the blower and delivered to the inside of the cleaning tube through the delivery hose, and the high-pressure air is discharged to the outside through the inclined blowing hole to blow and clean the dust and sand on the top surface of the photovoltaic panel body. The inclination angle of the inclined blowing hole points to the lower corner of the photovoltaic panel body. The inclination angle of the inclined blowing hole facilitates the downward discharge of dust and sand along both sides of the cleaning roller, reducing the secondary pollution and accumulation of dust and sand. At the same time, the cleaning roller is driven to rotate by the output shaft of the cleaning motor, and the cleaning roller further cleans the dust and sand that have not been blown off the top surface of the photovoltaic panel body. The movement of the column along the slide rail avoids the cleaning blind spot, improves the cleaning efficiency and cleaning effect, and ensures the comprehensiveness and thoroughness of the cleaning work.

[0069] Working principle:

[0070] Before use, firstly, the T-shaped blocks 3 of two adjacent mounting frames 1 are plugged into the T-shaped slots 2, multiple mounting frames 1 are connected, and then the mounting frame 1 is mounted on the top surface of the tripod 6 through the first bolt 11, and then the corresponding photovoltaic power generation panel body 4 is mounted on the appropriate mounting frame 1 through the hinge axis, and the above steps are repeated to facilitate the installation of multiple photovoltaic power generation panel bodies 4 to form a complete photovoltaic power generation array, and to facilitate the increase or decrease of the number of photovoltaic power generation panel bodies 4 to meet the power generation needs of different scales, facilitate the assembly and disassembly and maintenance of the photovoltaic power generation panel body 4, improve the convenience and flexibility of use, and reduce the operating cost;

[0071] After the installation is completed, the tilt angle of the photovoltaic panel body 4 is adjusted by flipping the assembly 5, and the rotating assembly 9 horizontally rotates the entire photovoltaic panel array to adapt to the change of the sun's position, ensuring that the photovoltaic panel can always receive the maximum amount of solar energy and improve the power generation efficiency. By selecting the bracket 12 of the appropriate length, the photovoltaic panel body 4 can be conveniently installed at a suitable height for use;

[0072] When adjusting the tilt angle of the photovoltaic power generation panel body 4, the output shaft of the second servo motor 510 drives the first screw rod 502 located in the middle to rotate, and at the same time, the traction wheel 507 rotates through the belt 508 and the pulleys 509 on both sides to transmit friction, so that the first screw rod 502 rotates synchronously, and the first screw rod 502 pushes the push block 503 to slide inside the protective block 501, and the push block 503 drives the slide 504 and the pulley 505 to move synchronously, and the pulley 505 slides with the inner wall of the C-shaped block 506 on the bottom surface of the photovoltaic power generation panel body 4, so that the push block 503 moves and drives the photovoltaic power generation panel body 4 to rotate around the hinge axis, thereby changing its tilt angle, facilitating the adjustment of the photovoltaic power generation panel body 4 to maintain the best angle with the sun, improving the power generation efficiency, realizing the rapid and accurate adjustment of the tilt angle of the photovoltaic power generation panel, and ensuring the stability of the photovoltaic power generation panel body 4 during the adjustment process;

[0073] Before adjusting the angle of the photovoltaic panel body 4, the block 511 is kept in the locked position on the slide 504 through the elastic force of the spring 514 and the Z-shaped block 513; when it is necessary to install and replace the pulley 505, the angle of the photovoltaic panel body 4 is adjusted to a suitable position to drive the C-shaped block 506 to move synchronously. After the pulley 505 is separated from the C-shaped block 506, the block 515 is driven to drive the block 511 to move downward, so that the block 511 slides along the Z-shaped block 513 through the through groove 512 and compresses the spring 514, thereby unlocking the lock, and the rotating wheel 516 is turned to engage the screw. The column is separated, and the pulley 505 and the stud can be taken out from the slide 504, which is convenient for replacement and installation. After replacement, the rotating wheel 516 is threadedly connected to the stud to fix the pulley 505, and the block 511 is reset under the elastic force of the spring 514, and the slide 504 is locked again, ensuring the stability of the photovoltaic panel body 4, reducing the movement or falling off of the pulley 505, ensuring the firmness and reliability of the pulley 505 during use, ensuring the stability and power generation efficiency of the photovoltaic panel body 4, simplifying the process of replacing the pulley 505, and reducing maintenance costs.

[0074] When the rotation angle of the photovoltaic power generation panel body 4 needs to be adjusted, the output shaft of the first servo motor 912 drives the rotating rod 910 to rotate, drives the worm helical teeth 911 to rotate, and makes the worm helical teeth 911 mesh with the worm gear 909, so that the worm gear 909 drives the bidirectional lead screw 906 to rotate. The rotation of the bidirectional lead screw 906 makes the two adjustment blocks 908 move on the lead screw, thereby driving the round rod 905 and the fixed block 904 to move. Since the connecting rod 903 connects the circular ring block 902 with the fixed block 904, the connecting rod 903 pushes the circular ring block 902 to rotate and drives The movable bracket 12 rotates, so that the bracket 12 drives the support member 7 and the rotating shaft 13 to rotate, and the rotating shaft 13 rotates along the base, and the entire device is conveniently installed in a suitable use position through the base 13. At this time, the support member 7 drives the tripod 6 to rotate, which is convenient for rotating the photovoltaic power generation panel body 4 installed on the tripod 6 to a suitable angle. The flexible adjustment of the rotation angle of the photovoltaic power generation panel body 4 adapts to the changes in the position of the sun at different times and seasons, ensures that the photovoltaic power generation panel always faces the sun, maximizes the power generation efficiency, reduces the floor space, and facilitates the installation and maintenance of the equipment;

[0075] Two adjacent rotating rods 910 are plugged into the slots 913 through the plug blocks 914 and fixed with connecting bolts, so that the rotation of one of the rotating rods 910 drives the connected rotating rod 910 to rotate at the same time, which is convenient for rotating multiple rotating rods 910 at the same horizontal position, and one of the T-shaped blocks 3 located at the outer end slides with the other T-shaped slot 2 located at the outer end, thereby improving the stability of multiple photovoltaic panel bodies 4 during rotation, facilitating the simultaneous rotation of multiple photovoltaic panel bodies 4 installed on multiple tripods 6, so that multiple rotating rods 910 at the same horizontal position rotate at the same time and at the same angle, ensuring that the multiple photovoltaic panel bodies 4 installed on the tripod 6 are synchronously adjusted to the optimal orientation, maintaining the smooth rotation of the photovoltaic panel body 4, reducing the number and complexity of required components, and reducing installation and maintenance costs, while reducing the additional costs incurred by individually adjusting the angle of each photovoltaic panel body 4.

[0076] When cleaning the photovoltaic panel body 4, the travel gear 1005 and the rack 1017 on the travel motor 1004 mesh together to move the column 1002 and the entire cleaning assembly 10 to a suitable position along the slide rail 1003. The height of the lifting block 1007 and the cleaning roller 1001 is adjusted to a suitable position by the drive of the third servo motor 1009 and the threaded connection of the lifting block 1007 and the second screw rod 1008. Then, the rotary electric cylinder 1010 is started to drive the cleaning roller 1001 and the cleaning tube 1012 to a suitable angle through the rotating table, so that the cleaning roller 1001 is in friction contact with the top surface of the photovoltaic panel body 4, and the cleaning tube 1012 is parallel to the photovoltaic panel body 4 with a gap, thereby ensuring the pertinence and efficiency of the cleaning work, improving the thoroughness and uniformity of the cleaning, ensuring the cleaning effect, and reducing the damage to the photovoltaic panel body 4.

[0077] At this time, the external air is sucked in by the blower 1014 and delivered to the inside of the cleaning tube 1012 through the delivery hose 1015, and the high-pressure air is discharged to the outside through the inclined blowing hole 1013 to blow and clean the dust and sand on the top surface of the photovoltaic panel body 4. The inclination angle of the inclined blowing hole 1013 points to the lower end corner of the photovoltaic panel body 4. The inclination angle of the inclined blowing hole 1013 facilitates the discharge of dust and sand downward along both sides of the cleaning roller 1001, reducing the secondary pollution and accumulation of dust and sand. At the same time, the cleaning roller 1001 is driven to rotate by the output shaft of the cleaning motor 1018. The cleaning roller 1001 further cleans the dust and sand that have not been blown off the top surface of the photovoltaic panel body 4. The movement of the column 1002 along the slide rail 1003 avoids the cleaning blind spot, improves the cleaning efficiency and cleaning effect, and ensures the comprehensiveness and thoroughness of the cleaning work.
