[0033] Under the action of the torsion force of the torsion spring 7, the protective film 6 is wound on the winding roller 5, and the two ends of the pull rod 8 are respectively in contact with the two first positioning blocks 31. Under the action of the two slide rails 30, the pull rod 8 can move on the fixed plate 2. When the pull rod 8 is driven to move toward the second positioning block 32, the pull rod 8 can pull the protective film 6 to release the protective film 6 from the winding roller 5. The winding roller 5 rotates on the rotating shaft 4, and the two torsion springs 7 undergo torsional deformation.

[0034] In this embodiment, the support assembly includes: a support shaft 9 fixedly installed at one end of the fixed plate 2, two support rods 10 symmetrically rotatably sleeved on the support shaft 9, and a moving block 11 slidably installed on the mounting base plate 1 through an adjusting component, and the end of the support rod 10 away from the fixed plate 2 is rotatably installed on the moving block 11; the adjusting component includes: a rotating rod 12 rotatably installed on the mounting base plate 1 and a driving motor 13 fixedly installed on the mounting base plate 1, the output shaft of the driving motor 13 is fixedly connected to the rotating rod 12, the rotating rod 12 is partially provided with threads, and the moving block 11 is threadedly sleeved on the rotating rod 12.

[0036] In this embodiment, the pulling assembly includes: a rotating shaft 14 installed on the mounting base plate 1, two winding rollers 15 symmetrically fixedly sleeved on the rotating shaft 14, two pull ropes 16 respectively wound around the two winding rollers 15, two guide wheels 17 symmetrically rotatably installed on the mounting base plate 1, and a transmission component for driving the rotating shaft 14 to rotate, and one end of the pull rope 16 passes through the guide wheel 17 and is fixedly connected to the pull rod 8.

[0037] During the rotation of the rotating shaft 14, the winding roller 15 will be driven to rotate. At the same time, the winding roller 15 will wind the pull rope 16 around the winding roller 15. The pull rope 16 will drive the pull rod 8 through the guide wheel 17, thereby driving the pull rod 8 to move away from the first positioning block 31, releasing the protective film 6 from the winding roller 5 and covering the fixed plate 2, thereby protecting the photovoltaic panel.

[0038] In this embodiment, a cylindrical groove is provided at one end of the rotating rod 12, and the transmission components include: a moving column 18 slidably inserted in the cylindrical groove, a spring rod 19 fixedly installed at one end of the moving column 18, a hexagonal block 20 fixedly installed at one end of the spring rod 19, a first bevel gear 21 rotatably installed on the mounting base plate 1 through a support block, a second bevel gear 22 fixedly sleeved on the rotating shaft 14, and a connecting block 23 fixedly installed on the side of the first bevel gear 21, and a hexagonal groove 24 is provided on a side of the connecting block 23 close to the hexagonal block 20, and the first bevel gear 21 is meshed and connected with the second bevel gear 22.

[0039] The movable column 18 is horizontally slidably installed in the cylindrical groove. When one end of the hexagonal block 20 is inserted into the hexagonal groove 24 opened in the connecting block 23, when the rotating rod 12 rotates, it will drive the movable column 18 to move and rotate, and at the same time drive the hexagonal block 20 to rotate together through the spring rod 19, and then drive the first bevel gear 21 to rotate through the hexagonal block 20 and the connecting block 23. Since the first bevel gear 21 is meshed and connected with the second bevel gear 22, the rotating shaft 14 will be driven to rotate through the second bevel gear 22, and the pull rope 16 will be wound around the winding roller 15.

[0040] In this embodiment, two mounting blocks 25 are symmetrically fixedly installed on the mounting base plate 1, and sliding rods 26 are horizontally slidably installed on the two mounting blocks 25. A stopper 27 is fixedly installed on one end of the two sliding rods 26 close to the moving block 11, and a telescopic spring 28 is sleeved on the sliding rod 26. The two ends of the telescopic spring 28 are respectively fixedly connected to the stopper 27 and the mounting block 25. An L-shaped connecting rod 29 is fixedly installed on the end of the sliding rod 26 away from the stopper 27, and one end of the connecting rod 29 is fixedly connected to the moving column 18.

[0041] The slide bar 26 is slidably mounted on the mounting block 25 through the telescopic spring 28. At the same time, the slide bar 26 is connected to the moving column 18 through the connecting rod 29. Under the elastic force of the telescopic spring 28, the slide bar 26 drives the moving column 18 to move into the cylindrical groove through the connecting rod 29, thereby driving the hexagonal block 20 to move out of the hexagonal groove 24. When the support rod 10 is in a vertical state, it can continue to drive the moving block 11 to move away from the drive motor 13. At this time, the moving block 11 will contact the two stoppers 27. , driving the slide bar 26 to move on the mounting block 25, and the slide bar 26 will drive the moving column 18 to move toward the spring rod 19 through the connecting rod 29, and the telescopic spring 28 will be compressed until the moving block 11 is disengaged from the thread opened on the rotating rod 12. At this time, the moving block 11 stops moving, and when the moving column 18 drives the spring rod 19 to move, the hexagonal block 20 will contact the connecting block 23, and the spring rod 19 will be compressed. During the rotation of the rotating rod 12, the hexagonal block 20 will be inserted into the hexagonal groove 24.

[0042] In this embodiment, two mounting rods 33 are symmetrically fixedly mounted on the mounting seat 3, and a V-shaped rain scraper 34 is fixedly mounted on one end of the two mounting rods 33. The rain scraper 34 is in sliding contact with the protective film 6, and a buffer component is provided on the rain scraper 34; when the hexagonal block 20 is moved out of the hexagonal groove 24, under the action of the torsion force of the torsion spring 7, the winding roller 5 will quickly rewind the protective film 6 on the winding roller 5, and during the winding process of the protective film 6, the rain scraper 34 will quickly contact the protective film 6 and move relative to the protective film 6, so that the rain scraper 34 can clean the residual rain or hail on the protective film 6 to prevent the rain or hail from being rolled up together with the protective film 6. To a certain extent, the drying time of the protective film 6 can be effectively reduced.

[0043] In this embodiment, mounting holes are symmetrically provided on the rain scraper 34, and the buffer assembly includes: two buffer rods 35 slidably installed in the two mounting holes, two round blocks 36 fixedly installed at one end of the two buffer rods 35, two buffer springs 37 and an impact block 38 fixedly installed at one end of the two buffer rods 35 away from the round block 36. The buffer spring 37 is sleeved on the buffer rod 35 and its two ends are fixedly connected to the impact block 38 and the rain scraper 34 respectively.

[0044] The buffer rod 35 and the buffer spring 37 can play a buffering role. When the pull rod 8 quickly hits the impact block 38, the impact force will be converted into the elastic potential energy of the buffer spring 37, which has a buffering and decelerating effect on the pull rod 8, reducing the impact force of the pull rod 8 on the first positioning block 31 and extending the service life of the first positioning block 31.

[0045] Working principle: In the present invention, the driving motor 13 can be started to drive the rotating rod 12 to rotate, and then the moving block 11 can be driven to move horizontally on the installation base plate 1 through the thread provided on the rotating rod 12. The moving block 11 can drive the fixed plate 2 to rotate on the installation base plate 1 through the support rod 10, thereby realizing the adjustment of the inclination angle of the fixed plate 2. The photovoltaic panel is driven to rotate through the fixed plate 2 to adjust the inclination angle of the photovoltaic panel, so that sunlight can be better irradiated on the photovoltaic panel, thereby improving the power generation efficiency of the photovoltaic panel.

[0046] When encountering bad weather, the driving motor 13 drives the rotating rod 12 to rotate, driving the moving block 11 to move away from the driving motor 13 until the moving block 11 is disengaged from the thread on the rotating rod 12. At the same time, the moving block 11 will contact the two blocks 27 during the movement, driving the slide bar 26 to move toward the defense line of the rotating shaft 14, and the telescopic spring 28 is compressed. One end of the slide bar 26 drives the moving column 18 to move toward the hexagonal groove 24 through the connecting rod 29, thereby inserting the hexagonal block 20 into the hexagonal groove 24. At this time, when the rotating rod 12 continues to rotate, the rotating shaft 14 will be driven to rotate through the first bevel gear 21 and the second bevel gear 22, and then the pull rope 16 will be wound around the winding roller 15, and the pull rod 8 will be pulled by the pull rope 16 to drive the protective film 6 to move, release the protective film 6 from the winding roller 5, and cover the fixed plate 2, so as to protect the photovoltaic panel.

[0047] After the bad weather is over, the driving motor 13 can be used to drive the rotating rod 12 to rotate in the opposite direction. At this time, under the action of the elastic force of the telescopic spring 28, the moving block 11 will engage with the thread on the rotating rod 12 again, thereby driving the moving block 11 to move in the direction of the driving motor 13. At the same time, the sliding rod 26 will drive the moving column 18 to move into the cylindrical groove through the connecting rod 29, and take the hexagonal block 20 out of the hexagonal groove 24. Under the action of the torsion force of the torsion spring 7, the winding roller 5 will quickly rewind the protective film 6 on the winding roller 5. During the winding process of the protective film 6, the rain scraper 34 will quickly contact the protective film 6 and move relative to the protective film 6, so that the rain scraper 34 can clean the rain or hail remaining on the protective film 6 to prevent the rain or hail from being rolled up with the protective film 6. To a certain extent, the drying time of the protective film 6 can be effectively reduced.

[0048] When the pull rod 8 quickly hits the impact block 38, the impact force is converted into elastic potential energy of the buffer spring 37, which has a buffering and decelerating effect on the pull rod 8, reducing the impact force of the pull rod 8 on the first positioning block 31 and extending the service life of the first positioning block 31.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any technician familiar with the profession, without departing from the scope of the technical solution of the present invention, according to the technical essence of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
