Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation device with adaptive light angle adjustment. Background Art

[0002] A photovoltaic power generation device is a device that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. The solar panel is the core component of the photovoltaic power generation device, which is composed of several thin-film photovoltaic cells connected together. When light shines on the surface of the cell, positive and negative ions in the cell are separated to form an electric current. The photovoltaic power generation device uses solar energy to generate electricity, without emissions and pollution, and is a green energy source;

[0003] After retrieval, a Chinese patent with the publication number CN221283112U provides a photovoltaic power generation panel frame that is convenient for angle adjustment. This device can freely adjust the inclination angle of the fixing frame and the photovoltaic power generation panel thereon, and can also be adjusted horizontally. The combination of these two adjustment methods can keep the photovoltaic power generation panel perpendicular to the sunlight at all times, making more effective use of solar energy. During the rainy season, the height of the photovoltaic power generation panel and the like can be raised to avoid damage to parts and reduce the service life of the photovoltaic power generation panel;

[0004] However, it is found in the use process that when adjusting the angle of this photovoltaic power generation panel frame design, it is necessary to separately equip each photovoltaic power generation panel with a motor and multiple electric telescopic rods for driving, which relatively increases the operation cost.

[0024] Through the above technical solution, the inclined angle of the inclined air blowing holes facilitates discharging dust and blowing sand downward along both sides of the cleaning roller, and the cleaning roller further cleans the dust and blowing sand that cannot be blown off on the top surface of the photovoltaic panel body.

[0025] The 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.

[0048] Embodiment 1

[0049] As Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10As shown in the figure, this embodiment provides a photovoltaic power generation device with adaptive light angle adjustment, including an installation frame 1.

[0050] It further includes a tripod 6. Multiple installation frames 1 are respectively installed on the top surface of the tripod 6. There is a gap between the bottom surface of the push block 503 and the top surface of the tripod 6. A support member 7 is fixedly provided on the bottom surface of the tripod 6.

[0051] The middle part of the support member 7 is connected to a bracket 12 through a flange. The length of the bracket 12 is not unique. A rotating shaft 13 is fixedly provided on the bottom surface of the bracket 12. The lower end of the rotating shaft 13 is rotatably connected to the base 8. Two grooves 14 are symmetrically formed on the top surface of the installation frame 1. The bottom of the groove 14 is threadedly connected to a first bolt 11 through a threaded hole. The lower end of the first bolt 11 is threadedly connected to the upper end of the tripod 6; the installation frame 1 is installed on the top surface of the tripod 6 through the first bolt 11, which facilitates the stable installation of the installation frame 1.

[0052] A traction wheel 507 is sleeved on the outer peripheral wall of the front end of the first lead screw 502 located in the middle. Two belts 508 are in frictional contact with the inside of the pulley groove of the traction wheel 507. The other ends of the belts 508 are in frictional contact with a pulley 509. The two pulleys 509 are respectively sleeved on the outer peripheral walls of the first lead screws 502 on both sides. A second servo motor 510 is installed on the installation frame 1 located in the middle through a mounting seat. The output shaft of the second servo motor 510 is coaxially connected to the first lead screw 502 located in the middle; the output shaft of the second servo motor 510 drives the first lead screw 502 located in the middle to rotate. At the same time, the traction wheel 507 rotates and is frictionally transmitted through the belts 508 and the pulleys 509 on both sides, so that the first lead screws 502 rotate synchronously.

[0053] The pulley 505 is mounted on the carriage 504 through a stud. A rotating wheel 516 is threadedly connected to the stud. Two clamping blocks 511 are symmetrically and slidably connected to the outer wall of the carriage 504. A through groove 512 is formed in the side wall of the clamping block 511. A Z-shaped block 513 is slidably connected inside the through groove 512. The Z-shaped block 513 is fixedly connected to the carriage 504. A spring 514 is fixedly provided on the top surface of the Z-shaped block 513. The top surface of the spring 514 is fixedly connected to the clamping block 511. A dial block 515 is fixedly provided at the lower end of the outer side wall of the clamping block 511. The clamping block 511 is kept in the locked position on the carriage 504 by the elastic force cooperation of the spring 514 and the Z-shaped block 513.

[0054] Before use, first insert the T-shaped blocks 3 of two adjacent mounting frames 1 into the T-shaped grooves 2 to connect multiple mounting frames 1. Then, install the mounting frames 1 on the top surface of the tripod 6 through the first bolts 11. Then, install the corresponding photovoltaic panel body 4 on the appropriate mounting frame 1 through the hinge shaft. Repeating the above steps facilitates the installation of multiple photovoltaic panel bodies 4 to form a complete photovoltaic power generation array, which is convenient for increasing or decreasing the number of photovoltaic panel bodies 4 to meet the power generation requirements of different scales, facilitates the assembly, disassembly and maintenance of the photovoltaic panel bodies 4, improves the use convenience and flexibility, and reduces the operation cost.

By selecting a bracket 12 with an appropriate length, it is convenient to install the photovoltaic panel body 4 at an appropriate use height.

[0056] When adjusting the inclination angle of the photovoltaic panel body 4, the output shaft of the second servo motor 510 drives the first lead screw 502 located in the middle to rotate. At the same time, the traction wheel 507 rotates and frictionally drives the belt wheels 509 on both sides through the belt 508, so that the first lead screw 502 rotates synchronously. The first lead screw 502 pushes the push block 503 to slide inside the protective block 501. The push block 503 drives the carriage 504 and the pulley 505 to move synchronously. The pulley 505 slides inside the inner wall of the C-shaped block 506 at the bottom surface of the photovoltaic panel body 4, so that the movement of the push block 503 drives the photovoltaic panel body 4 to rotate around the hinge shaft, thereby changing its inclination angle, facilitating the adjustment of the photovoltaic panel body 4 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 smoothness of the photovoltaic panel body 4 during the adjustment process.

[0057] Before adjusting the angle of the photovoltaic panel body 4, the clamping block 511 is held in the locked position on the carriage 504 by the elastic force cooperation 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, driving the C-shaped block 506 to move synchronously. After separating the pulley 505 from the C-shaped block 506, the toggle block 515 is toggled to drive the clamping block 511 to move downward, so that the clamping block 511 slides along the Z-shaped block 513 through the through groove 512 and compresses the spring 514, thereby realizing unlocking. Rotating the rotating wheel 516 to separate from the stud, the pulley 505 and the stud can be taken out from the carriage 504, which facilitates replacement and installation. After replacement, the rotating wheel 516 is threadedly connected to the stud to fix the pulley 505. The clamping block 511 is reset under the elastic force of the spring 514, locking the carriage 504 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, guaranteeing the stability and power generation efficiency of the photovoltaic panel body 4, simplifying the process of replacing the pulley 505, and reducing the maintenance cost.

There are multiple rotating rods 910. One end of the rotating rod 910 is provided with a slot 913, and the other end of the rotating rod 910 is fixedly provided with a plug 914. The plug 914 is inserted and matched with the slot 913. The plug 914 is inserted and matched with the slot 913 through a connecting bolt. The adjacent two rotating rods 910 are inserted through the plug 914 and the slot 913 and fixed by the connecting bolt, which improves the stability of the rotation of multiple photovoltaic panel bodies 4 and facilitates the simultaneous rotation of the photovoltaic panel bodies 4 installed on multiple tripods 6.

[0061] When it is necessary to adjust the rotation angle of the photovoltaic panel body 4, the output shaft of the first servo motor 912 drives the rotating rod 910 to rotate, drives the worm spiral tooth 911 to rotate, makes the worm spiral tooth 911 meshingly drive to the worm gear 909, makes the worm gear 909 drive the bidirectional lead screw 906 to rotate. The rotation of the bidirectional lead screw 906 causes the two adjusting blocks 908 to move on the lead screw, and then drives the round rod 905 and the fixed block 904 to move. Since the connecting rod 903 connects the ring block 902 and the fixed block 904, the connecting rod 903 pushes the ring block 902 to rotate and drives the bracket 12 to rotate, so that the bracket 12 drives the support member 7 and the rotating shaft 13 to rotate. The rotating shaft 13 rotates along the base. It is convenient to install the whole device at a suitable use position through the base 13. At this time, the support member 7 drives the tripod 6 to rotate, which is convenient to rotate the photovoltaic panel body 4 installed on the tripod 6 to a suitable angle. The flexible adjustment of the rotation angle of the photovoltaic panel body 4 adapts to the sun position changes at different times and seasons, ensures that the photovoltaic panel always faces the sun, maximizes the power generation efficiency, reduces the floor area, and facilitates the installation and maintenance of the equipment;

[0062] Adjacent two rotating rods 910 are inserted and connected through insertion blocks 914 and slots 913, and fixed by connecting bolts. When one of the rotating rods 910 rotates, it drives the connected rotating rod 910 to rotate, facilitating the rotation of multiple rotating rods 910 at the same horizontal position. One of the T-shaped blocks 3 at the outer end slides with another T-shaped groove 2 at the outer end, improving the stability when multiple photovoltaic panel bodies 4 rotate, facilitating the simultaneous rotation of the photovoltaic panel bodies 4 installed on multiple tripods 6, enabling multiple rotating rods 910 at the same horizontal position to rotate simultaneously and at the same angle, ensuring that multiple photovoltaic panel bodies 4 installed on the tripods 6 are synchronously adjusted to the optimal orientation, maintaining the smooth rotation of the photovoltaic panel bodies 4, reducing the number and complexity of required components, also reducing the installation and maintenance costs, and at the same time reducing the additional costs generated by individually adjusting the angles of each photovoltaic panel body 4.

[0064] As Figure 1 , Figure 2 , Figure 11 , Figure 12 and Figure 13 As shown in

[0065] , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that the cleaning component 10 includes a column 1002. A slide rail 1003 is fixedly provided on the top surface of the mounting frame 1. A rack 1017 is provided on one side of the slide rail 1003, and the bottom surface of the rack 1017 is fixedly connected to the top surface of the mounting frame 1. The lower end of the column 1002 is slidably connected to the slide rail 1003. A traveling motor 1004 is installed on the outer peripheral wall of the lower end of the column 1002 through a mounting seat. A traveling gear 1005 is coaxially connected to the output shaft of the traveling motor 1004. The central axis of the traveling gear 1005 is rotatably connected to the column 1002 through a positioning block 1006. The lower end of the traveling gear 1005 is meshed with the rack 1017. A lifting block 1007 is slidably connected to the column 1002; through the meshing action of the traveling gear 1005 on the traveling motor 1004 and the rack 1017, the column 1002 and the entire cleaning component 10 are moved along the slide rail 1003 to a suitable position.

[0065] One end of the lifting block 1007 is threadedly connected with a second lead screw 1008 through a threaded hole. A third servo motor 1009 is installed on the top surface of the column 1002 through a mounting seat. The output shaft of the third servo motor 1009 is coaxially connected to the second lead screw 1008. Both ends of the second lead screw 1008 are respectively rotatably connected to a stabilizing block 1016, and the two stabilizing blocks 1016 are respectively fixedly connected to the column 1002. The other end of the lifting block 1007 is installed with a rotary cylinder 1010 through a mounting seat; through the driving of the third servo motor 1009 and the threaded connection of the lifting block 1007 and the second lead screw 1008, the height of the lifting block 1007 and the cleaning roller 1001 is adjusted to a suitable position.

[0066] A rotating block 1011 is fixedly installed on the rotating table of the rotary electric cylinder 1010. One end of the cleaning roller 1001 is rotatably connected to the rotating block 1011. Two cleaning pipes 1012 are fixedly installed on the rotating block 1011. A plurality of inclined air blowing holes 1013 are communicated with the outer wall of the cleaning pipe 1012 in a uniformly arranged structure. A blower 1014 is installed on the top surface of the lifting block 1007 through a mounting seat. The air outlet end of the blower 1014 is communicated with two conveying hoses 1015. The conveying hoses 1015 are communicated with the cleaning pipes 1012. A cleaning motor 1018 is installed on the rotating block 1011 through a mounting seat. The output shaft of the cleaning motor 1018 is coaxially connected to the cleaning roller 1001. The cleaning roller 1001 is rotatably connected to the rotating block 1011; the inclination angle of the inclined air blowing holes 1013 facilitates discharging dust and sand along both sides of the cleaning roller 1001 downward. The cleaning roller 1001 further cleans the dust and sand that cannot be blown off on the top surface of the photovoltaic power generation panel body 4.

[0067] When cleaning the photovoltaic power generation panel body 4, through the meshing action of the traveling gear 1005 on the traveling motor 1004 and the rack 1017, the column 1002 and the entire cleaning assembly 10 are moved along the slide rail 1003 to a suitable position. Through the driving of the third servo motor 1009 and the threaded connection of the lifting block 1007 and the second lead screw 1008, the height of the lifting block 1007 and the cleaning roller 1001 is adjusted to a suitable position. Then, the rotary electric cylinder 1010 is started, and the rotating block 1011 drives the cleaning roller 1001 and the cleaning pipe 1012 to a suitable angle through the rotating table, so that the cleaning roller 1001 is in frictional contact with the top surface of the photovoltaic power generation panel body 4, and the cleaning pipe 1012 is parallel to the photovoltaic power generation panel body 4 and has a gap, ensuring the pertinence and high efficiency of the cleaning work, improving the thoroughness and uniformity of the cleaning, guaranteeing the cleaning effect, and reducing the damage to the photovoltaic power generation panel body 4;

[0068] At this time, the blower 1014 sucks external air and conveys it to the inside of the cleaning pipe 1012 through the conveying hose 1015. High-pressure air is discharged to the outside through the inclined air blowing holes 1013 to blow and clean the dust and sand on the top surface of the photovoltaic power generation panel body 4. The inclination angle of the inclined air blowing holes 1013 points to the lower corner of the photovoltaic power generation panel body 4. The inclination angle of the inclined air blowing holes 1013 facilitates discharging dust and sand along both sides of the cleaning roller 1001 downward, reducing the secondary pollution and accumulation of dust and sand. At the same time, the output shaft of the cleaning motor 1018 drives the cleaning roller 1001 to rotate, and the cleaning roller 1001 further cleans the dust and sand that cannot be blown off on the top surface of the photovoltaic power generation panel body 4. Through the movement of the column 1002 along the slide rail 1003, the cleaning blind area is avoided, the cleaning efficiency and cleaning effect are improved, and the comprehensiveness and thoroughness of the cleaning work are ensured.

[0069] Working principle:

[0070] Before use, first insert the T-shaped blocks 3 of two adjacent mounting frames 1 into the T-shaped grooves 2 to connect multiple mounting frames 1. Then, mount the mounting frames 1 on the top surface of the tripod 6 through the first bolts 11. Next, install the corresponding photovoltaic panel body 4 on the appropriate mounting frame 1 through the hinge shaft. Repeating the above steps facilitates the installation of multiple photovoltaic panel bodies 4 to form a complete photovoltaic power generation array, which is convenient for increasing or decreasing the number of photovoltaic panel bodies 4 to meet the power generation requirements of different scales, facilitates the assembly, disassembly and maintenance of the photovoltaic panel bodies 4, improves the use convenience and flexibility, and reduces the operation cost;

[0071] After the installation is completed, adjust the tilt angle of the photovoltaic panel body 4 through the flipping assembly 5, and rotate the entire photovoltaic panel array horizontally through the rotating assembly 9 to adapt to the change of the sun's position, ensuring that the photovoltaic panel can always receive the maximum amount of solar energy, improving the power generation efficiency. By selecting a bracket 12 with an appropriate length, it is convenient to install the photovoltaic panel body 4 at an appropriate use height;

[0072] When adjusting the tilt angle of the photovoltaic panel body 4, the output shaft of the second servo motor 510 drives the first lead screw 502 located in the middle to rotate. At the same time, the traction wheel 507 rotates and frictionally drives the belt wheels 509 on both sides through the belt 508, causing the first lead screw 502 to rotate synchronously. The first lead screw 502 pushes the push block 503 to slide inside the protective block 501. The push block 503 drives the carriage 504 and the pulley 505 to move synchronously. The pulley 505 slides inside the inner wall of the C-shaped block 506 at the bottom of the photovoltaic panel body 4, causing the push block 503 to move and drive the photovoltaic panel body 4 to rotate around the hinge shaft, thereby changing its tilt angle, facilitating the adjustment of the photovoltaic 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 panel, and ensuring the stability of the photovoltaic panel body 4 during the adjustment process;

[0073] Before adjusting the angle of the photovoltaic panel body 4, the clamping block 511 is held in the locked position on the carriage 504 by the elastic force cooperation 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, driving the C-shaped block 506 to move synchronously. After separating the pulley 505 from the C-shaped block 506, the toggle block 515 is toggled to drive the clamping block 511 to move downward, so that the clamping block 511 slides along the Z-shaped block 513 through the through groove 512 and compresses the spring 514, thereby realizing unlocking. Rotating the rotating wheel 516 to separate from the stud can remove the pulley 505 and the stud from the carriage 504, which facilitates replacement, installation and use; after replacement, the rotating wheel 516 is threadedly connected to the stud to fix the pulley 505, and the clamping block 511 is reset under the elastic force of the spring 514 to lock the carriage 504 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 the maintenance cost.

[0074] When it is necessary to adjust the rotation angle of the photovoltaic panel body 4, the output shaft of the first servo motor 912 drives the rotating rod 910 to rotate, driving the worm spiral tooth 911 to rotate, so that the worm spiral tooth 911 is meshed and transmitted to the worm gear 909, and the worm gear 909 drives the bidirectional lead screw 906 to rotate. The rotation of the bidirectional lead screw 906 causes the two adjusting blocks 908 to move on the lead screw, and then drives the round rod 905 and the fixed block 904 to move. Since the connecting rod 903 connects the ring block 902 and the fixed block 904, the connecting rod 903 pushes the ring block 902 to rotate and drives the bracket 12 to rotate, so that the bracket 12 drives the support member 7 and the rotating shaft 13 to rotate. The rotating shaft 13 rotates along the base, and the entire device can be conveniently installed at a suitable use position through the base 13. At this time, the support member 7 drives the tripod 6 to rotate, facilitating the rotation of the photovoltaic panel body 4 installed on the tripod 6 to a suitable angle. The flexible adjustment of the rotation angle of the photovoltaic panel body 4 adapts to the changes in the sun's position at different times and seasons, ensures that the photovoltaic panel always faces the sun, maximizes the power generation efficiency, reduces the floor area, and facilitates the installation and maintenance of the equipment;

[0075] Adjacent two rotating rods 910 are inserted and connected through insertion blocks 914 and slots 913 and fixed by connecting bolts. When one of the rotating rods 910 rotates, it drives the connected rotating rod 910 to rotate, facilitating the rotation of multiple rotating rods 910 at the same horizontal position. One of the T-shaped blocks 3 at the outer end slides with another T-shaped groove 2 at the outer end, improving the stability of the rotation of multiple photovoltaic panel bodies 4, facilitating the simultaneous rotation of the photovoltaic panel bodies 4 installed on multiple tripods 6, enabling multiple rotating rods 910 at the same horizontal position to rotate simultaneously and at the same angle, ensuring that 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 bodies 4, reducing the number and complexity of required components, also reducing the installation and maintenance costs, and at the same time reducing the additional costs generated by individually adjusting the angles of each photovoltaic panel body 4.

[0076] When cleaning the photovoltaic panel body 4, through the meshing of the traveling gear 1005 on the traveling motor 1004 and the rack 1017, the column 1002 and the entire cleaning assembly 10 are moved along the slide rail 1003 to a suitable position. Through the drive of the third servo motor 1009 and the threaded connection of the lifting block 1007 and the second lead screw 1008, the height of the lifting block 1007 and the cleaning roller 1001 is adjusted to a suitable position. Then, the rotary cylinder 1010 is started, and through the rotary table, the rotating block 1011 drives the cleaning roller 1001 and the cleaning pipe 1012 to a suitable angle, making the cleaning roller 1001 in frictional contact with the top surface of the photovoltaic panel body 4, and the cleaning pipe 1012 is parallel to the photovoltaic panel body 4 with a gap, ensuring the pertinence and high efficiency of the cleaning work, improving the thoroughness and uniformity of the cleaning, guaranteeing the cleaning effect, and reducing the damage to the photovoltaic panel body 4;

[0077] At this time, the blower 1014 sucks external air and conveys it through the delivery hose 1015 into the cleaning pipe 1012, and discharges high-pressure air to the outside through the inclined air holes 1013 to blow and clean the dust and sand on the top surface of the photovoltaic panel body 4. The inclined angle of the inclined air holes 1013 points to the lower corner of the photovoltaic panel body 4. The inclined angle of the inclined air holes 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 output shaft of the cleaning motor 1018 drives the cleaning roller 1001 to rotate, and the cleaning roller 1001 further sweeps the dust and sand that cannot be blown off on the top surface of the photovoltaic panel body 4. Through the movement of the column 1002 along the slide rail 1003, the cleaning blind area is avoided, the cleaning efficiency and cleaning effect are improved, and the comprehensiveness and thoroughness of the cleaning work are ensured.

[0078] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
