However, existing solar photovoltaic modules face many challenges in practical application, especially in terms of surface cleaning.

[0003] Firstly, solar photovoltaic modules are often exposed to the natural environment for a long time, especially in arid, dusty or seasonal precipitation areas. Dust, sand particles, bird droppings, leaves and other pollutants can easily adhere to the surface of the photovoltaic module, hindering the sunlight from shining, and thus significantly reducing its light energy conversion efficiency. In addition, under adverse weather conditions such as rain and snow, the surface of the photovoltaic module may be covered with water or ice, which not only affects the power generation efficiency, but also accelerates the aging and damage of the photovoltaic equipment, reducing its service life.

[0014] Compared with the prior art, the present application has the following advantages: 1.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0020] Embodiment one Please refer to Figures 1-18 As shown in the figure, the present application discloses a solar photovoltaic module convenient to clean, which comprises a frame mechanism 1, the frame mechanism 1 comprises a main beam 11, two side beams 12 are installed on the both ends of the main beam 11, a plurality of middle beams 13 are installed equidistantly between the two side beams 12, a sub beam 16 is installed on the other end of the side beam 12 and the middle beam 13, a side rod 14 is fixed on the bottom of the side beam 12 and the middle beam 13, a plurality of stop columns 15 are fixed on the top surface of the side rod 14, and a storage chute 17 is arranged on the inner side of the side beam 12 and the two sides of the middle beam 13. The top surface of the main beam 11 is provided with a water collecting mechanism 2, which comprises a support column 21 fixed to the top surface of the main beam 11, and a water collecting tank 22 mounted at the top of the support column 21, and a plurality of water distribution chambers 24 arranged in the water collecting tank 22, and a plurality of water injection rods 26 arranged on the side surface of the water collecting tank 22; The power generation mechanism 5 is slidably arranged in the receiving sliding groove 17, and comprises a rotating motor 51 slidably connected in the receiving sliding groove 17, and a frame 52 connected to the output end of the rotating motor 51, and a top frame 53 and a bottom frame 54, both ends of which are fixedly connected to both ends of the frame 52, and a solar panel 55 arranged in the space surrounded by the frame 52, the top frame 53 and the bottom frame 54, and a receiving groove 56 arranged on the frame 52; The expansion mechanism 6 is arranged in the receiving groove 56, and comprises a rotating shaft 61 rotatably connected in the receiving groove 56 by a torsion spring, and a blocking strip 62 and an expansion plate 63 fixed to the surface of the rotating shaft 61, and the expansion plate 63 is clamped and connected to the inside of the receiving groove 56, and a rotation preventing plate 66 slidably connected to the inside of the frame 52, and the blocking strip 62 abuts against the rotation preventing plate 66, and two blocking blocks 67 symmetrically slidably connected to the inside of the frame 52, and the two blocking blocks 67 abut against the rotation preventing plate 66; The cleaning mechanism 7 is arranged in the top frame 53, and comprises a housing 71, a water storage compartment 76 arranged in the inside of the housing 71, and an opening arranged at the bottom of the water storage compartment 76, and a cleaning belt 79 and a convex cylinder 75 rotatably connected to the inside of the housing 71, and the convex cylinder 75 abuts against the cleaning belt 79.

[0021] Further, the solar photovoltaic module is designed in a modular manner, and each power generation mechanism 5 is controlled by the rotating motor 51. In bad weather such as rainy and snowy days, the solar photovoltaic module can be recycled, and when recycling, the rotating motor 51 drives the power generation mechanism 5 to rotate by ninety degrees (counterclockwise according to the attached drawings), so that the power generation mechanism 5 is erected. Then the driving motor 81 in the secondary beam 16 is started, and slides into the receiving sliding groove 17 in the side beam 12 and the middle beam 13, so that the abutting sliding block 82 is connected with the closest power generation mechanism 5 (according to the attached drawings). Figure 1 Figure 1 ​The power generation mechanism 5 closest to the main beam 11 is called the front end power generation mechanism 5, and the power generation mechanism 5 closest to the auxiliary beam 16 is called the end power generation mechanism 5, and the like. The pushing motor 81 drives the end power generation mechanism 5 to slide between the side beam 12 or the middle beam 13 through the docking slider 82, so that a plurality of power generation mechanisms 5 are sequentially abutted together and slide together towards the main beam 11. When two adjacent power generation mechanisms 5 abut against each other, they are combined together through the cooperation of the front locking groove 693 on the front frame 52 and the rear locking block 691 in the rear frame 52. When the rear power generation mechanism 5 drives the front end power generation mechanism 5 to slide a certain distance, the rotating motor 51 in the front end power generation mechanism 5 triggers the storage mechanism 3, so that the folding umbrella 36 is unfolded to protect all the power generation mechanisms 5 gathered on the side of the main beam 11 from rain and snow erosion.

[0022] During the long-term power generation of the power generation mechanism 5, the surface of the solar panel 55 will be covered with dust, thereby reducing the light conversion efficiency. In order to ensure the light conversion efficiency of the solar panel 55, it is necessary to clean the solar panel 55. Therefore, after the storage mechanism 3 is triggered for a certain time, the water inlet 58 on each top frame 53 is in communication with the water outlet 28 on the water injection rod 26, and at the same time, the storage mechanism 3 drives the on-off mechanism 4 to move, so that the water distribution port 25 is closed and the water outlet 28 is opened. The water in the water distribution chamber 24 enters the cleaning mechanism 7 in the top frame 53 through the water outlet 28. After the cleaning mechanism 7 is filled with a certain amount of water, the weight increases, and the seventh spring 73 cannot support the weight of the cleaning mechanism 7. Under the action of gravity, the cleaning mechanism 7 slides down along the cleaning sliding groove 59. During this process, the water storage bin 76 sprays water to wet the cleaning belt 79, and at the same time, the cleaning belt 79 abuts against the solar panel 55 to clean the solar panel 55.

[0023] Example Two This embodiment is an explanation and description based on Example 1. For details, please refer to Figures 1-18 The top surface of the side beam 12 is provided with the storage mechanism 3, which comprises a rotating gear 31 rotatably connected to the inside of one end of the side beam 12, two storage racks 32 simultaneously meshed with the rotating gear 31, one side surface of one of the storage racks 32 being fixedly provided with a push plate 33 slidingly connected in the storage sliding groove 17, and the rotating motor 51 abutting against the push plate 33. The end of the storage rack 32 is provided with a first spring 34. One end of the top surface of the frame 52 is fixedly provided with a folding umbrella 36, and the bottom end of the folding umbrella 36 is fixedly provided with a plurality of stable sliding blocks 35, and one of the stable sliding blocks 35 is fixedly provided on the top surface of the other storage rack 32.

[0024] The end of the display board 63 is fixed with a convex strip 64, the bottom surface of the side beam 12 and the middle beam 13 is equidistantly provided with a plurality of recesses matched with the convex strip 64, the fourth spring 65 is internally installed in the side frame 52, and the fourth spring 65 abuts against the anti-rotation plate 66, the fifth spring 68 is also internally installed in the side frame 52, and the fifth spring 68 abuts against the blocking block 67, the sixth spring 69 is installed in the connecting hole 57, the locking block 691 is slidingly connected in the connecting hole 57, and one end of the sixth spring 69 abuts against the locking block 691, and the side surface of the side frame 52 is symmetrically fixed with two connecting blocks 692, the connecting blocks 692 are slidingly connected in the connecting hole 57, the surface of the connecting block 692 is provided with a locking groove 693, and the locking block 691 is clamped and connected with the locking groove 693.

[0025] A plurality of pushing mechanisms 8 are internally installed in the sub-beam 16, the pushing mechanism 8 comprises a pushing motor 81, the pushing motor 81 is internally installed in the sub-beam 16, and the pushing motor 81 is slidingly connected in the corresponding receiving sliding groove 17, the side surface of the pushing motor 81 is installed with a butt joint sliding block 82, the butt joint sliding block 82 is internally provided with a butt joint groove 83, the butt joint sliding block 82 is symmetrically installed with the eighth spring 85 internally, the butt joint groove 83 is symmetrically slidingly connected with a connecting head 84, and one end of the eighth spring 85 is installed on the connecting head 84, a splicing block 86 is fixed on the side surface of one of the side frames 52, and the splicing block 86 is slidingly connected in the butt joint groove 83, the two side surfaces of the splicing block 86 are provided with splicing grooves 87, and the connecting head 84 is clamped and connected in the corresponding splicing groove 87.

[0026] Further, after the rotating motor 51 drives the power generation mechanism 5 to rotate by ninety degrees, the side frame 52 is vertical, the display board 63 loses the restriction of the side beam 12 or the middle beam 13, the torsional spring drives the rotating shaft 61 to rotate by ninety degrees, the blocking strip 62 fixed on the rotating shaft 61 rotates together with the display board 63 (after rotating by ninety degrees, the display board 63 is perpendicular to the surface of the side frame 52). Then the pushing motor 81 in the sub-beam 16 is started, slidingly enters the receiving sliding groove 17 on the side beam 12 and the middle beam 13, and drives the butt joint sliding block 82 to move together, when the butt joint sliding block 82 abuts against the end side frame 52, the splicing block 86 fixed on the end side frame 52 is inserted into the butt joint groove 83 in the butt joint sliding block 82, at the same time, the eighth spring 85 in the butt joint sliding block 82 drives the connecting head 84 to be inserted into the splicing groove 87, so that the splicing block 86 is connected with the butt joint sliding block 82 as a whole. The pushing motor 81 drives the end power generation mechanism 5 to move close to the main beam 11 through the butt joint sliding block 82, and the rotating motor 51 on the side surface of the end side frame 52 also slides in the receiving sliding groove 17. With the movement of the end power generation mechanism 5, it will abut against the previous power generation mechanism 5 in sequence, and finally all the power generation mechanisms 5 abut against each other and move close to the main beam 11. During the sliding of the power generation mechanism 5 along the receiving sliding groove 17, the display board 63 abuts against the stop column 15 on the side beam 14, because the display board 63 can rotate to the right through the rotating shaft 61 (refer to the attached drawings), so the stop column 15 cannot prevent the power generation mechanism 5 from moving through the display board 63. Figure 15 ​

[0027] When the rear power generation mechanism 5 is in contact and drives the front power generation mechanism 5 to slide, the rotating motor 51 in the front power generation mechanism 5 is in contact with the push plate 33 in the receiving sliding groove 17, and the push plate 33 drives the stable sliding block 35 fixedly connected with the receiving rack 32 to slide through the cooperation of the receiving rack 32 and the rotating gear 31 (the folding tent 36 is composed of several U-shaped rods and canvas, and the bottom end of each U-shaped rod is provided with a stable sliding block 35, and the stable sliding block 35 at the head end is fixed on the edge beam 12, and the stable sliding block 35 at the tail end is fixed on one of the receiving racks 32, and the other stable sliding blocks 35 slide in the sliding groove opened on the top surface of the edge beam 12, refer to the direction close to the main beam 11 as the head end, and the direction away from the main beam 11 as the tail end), the stable sliding block 35 sliding with the receiving rack 32 drives the folding tent 36 to unfold, and all the power generation mechanisms 5 are protected from wind and snow erosion. Figure 3

[0028] During the mutual contact of the adjacent power generation mechanisms 5, the connecting block 692 on the front edge frame 52 is inserted into the connecting hole 57 on the rear edge frame 52, the lock block 691 in the connecting hole 57 is inserted into the lock groove 693 on the connecting block 692, so that the two adjacent power generation mechanisms 5 are combined together (the resistance of the lock groove 693 and the lock block 691 is smaller than the resistance of the stop column 15 to the unfolding plate 63), and the connecting block 692 is inserted into the connecting hole 57 while pushing the two blocking blocks 67 to slide up and down (according to the orientation, refer to the direction close to the main beam 11 as the head end, and the direction away from the main beam 11 as the tail end), and the restriction of the anti-rotation plate 66 is released, so that the restriction of the blocking strip 62 by the anti-rotation plate 66 is released, and the rotating shaft 61 can rotate freely, and the unfolding plate 63 can swing left and right (refer to the direction close to the main beam 11 as the head end, and the direction away from the main beam 11 as the tail end). Figure 15 Figure 15 Before the connecting block 692 is inserted into the connecting hole 57, the anti-rotation plate 66 is blocked by the blocking block 67 and cannot slide freely, thereby blocking the blocking strip 62, so that the rotating shaft 61 cannot rotate to the left, and the unfolding plate 63 can only rotate to the right following the rotating shaft 61). When the several power generation mechanisms 5 are unfolded, the propulsion mechanism 8 pulls the tail end power generation mechanism 5 to pull back the several power generation mechanisms 5 one by one to the initial position. As shown in Figure 18 ​​As shown in the attached diagram, the unfolding mechanism 6 within the front frame 52 lacks structures such as the anti-rotation plate 66, blocking block 67, connecting hole 57, and locking block 691. Therefore, the rotating shaft 61, restricted by the blocking strip 62, can only rotate the unfolding plate 63 upwards by 90 degrees (after rotating 90 degrees, the blocking strip 62 will abut against the inner wall of the frame 52). When the front power generation mechanism 5 slides to its initial position, the unfolded plate 63 just abuts against the corresponding stop post 15. As the plate 63 has been described above, it cannot continue to rotate. The stop post 15 stops the sliding of the front-end power generation mechanism 5 by intercepting it through the display panel 63. When the front-end power generation mechanism 5 separates from the next power generation mechanism 5, the connecting block 692 on the front frame 52 separates from the connecting hole 57 on the next frame 52, and the locking block 691 disengages from the locking groove 693. The separation of the connecting block 692 causes the blocking block 67 in the next frame 52 to reset, re-restraining the anti-rotation plate 66, thereby restricting the blocking strip 62, so that the rotating shaft 61 cannot drive the display panel 63 to rotate to the left (according to the appendix). Figure 15 (The orientation of the second power generation mechanism 5) When the second power generation mechanism 5 returns to its initial position, if the separation method of the front power generation mechanism 5 is the same, the second power generation mechanism 5 is also intercepted by the corresponding stop column 15. The subsequent power generation mechanisms 5 are reset in sequence in the above manner until the end power generation mechanism 5 is intercepted by the corresponding stop column 15. Then, the splicing block 86 separates from the docking groove 83, the connector 84 separates from the splicing groove 87, the propulsion mechanism 8 returns to the sub-beam 16, and finally the rotation motor 51 in each power generation mechanism 5 starts, causing the power generation mechanism 5 to rotate 90 degrees in the opposite direction and return to the horizontal posture. During the process of the power generation mechanism 5 returning to the horizontal posture, the display plate 63 is squeezed by the side beam 12 or the middle beam 13 and rotated and returned to the storage groove 56. The protrusion 64 on the display plate 63 is engaged in the groove at the bottom of the side beam 12 or the middle beam 13, so that the power generation mechanism 5 cannot continue to rotate.

[0031] The side of the frame 52 is provided with a connecting hole 57, the top surface of the top frame 53 is symmetrically provided with two water injection openings 58, the water injection openings 58 are communicated with the water outlet 28, the inner side of the frame 52 is provided with a cleaning sliding groove 59, and the inside of the cleaning sliding groove 59 is provided with a rotating rack 591.

[0032] The two sides of the shell 71 are fixed with side blocks 72, the side blocks 72 are slidingly connected in the cleaning sliding groove 59, the cleaning sliding groove 59 is installed with a seventh spring 73, the side blocks 72 abut against the seventh spring 73, the two ends of the convex stripe cylinder 75 are fixedly connected with the cleaning gear 74 penetrating through the side of the shell 71, the cleaning gear 74 is slidingly connected in the cleaning sliding groove 59, and the cleaning gear 74 is meshingly connected with the rotating rack 591, the side of the shell 71 is provided with a water inlet 77, and the water inlet 77 is communicated with the water injection opening 58 through a hose, the inside of the shell 71 is rotatably connected with two rollers 78, the surfaces of the two rollers 78 are rotatably connected with a cleaning belt 79, and the cleaning belt 79 abuts against the solar panel 55.

[0033] Furthermore, during rainy weather, rainwater drips onto the cover 23 and flows down the cover 23 into the water collection tank 22. Simultaneously, the cover 23 shields the top of the water collection tank 22, preventing water evaporation and preventing debris such as dead branches and leaves from falling into the tank. Initially, the sealing plug 491 does not seal the water outlet 25, and the through-stop plate 45 seals each outlet 28. After collecting rainwater, the water collection tank 22 fills each water distribution chamber 24 with water through the water outlet 25. After all the power generation mechanisms 5 enter the folding awning 36, the water inlet 58 on each top frame 53 connects with the corresponding water outlet 28 on the water inlet rod 26. During the sliding process of the front-end rotating motor 51 pushing the push plate 33, the push plate 33 abuts against and pushes the push column 41. The sliding of the push column 41 not only causes the second spring 42 to contract but also pushes the relay rod 43 and the squeezing wedge 46 to move. The relay rod 43, through the connecting rod 44, drives the switching plate 45 to shift, connecting the water inlet chamber 27 with the water outlet 28. The squeezing wedge 46 squeezes the lifting wedge 47, causing the lifting wedge 47 to slide upwards (according to the appendix). Figure 5 (Position), the lifting wedge 47 pushes the sealing plug 491 against the water outlet 25 through the lifting rod 48, sealing the water outlet 25. Water in the water collection tank 22 cannot enter the water distribution chamber 24. At the same time, water in the water distribution chamber 24 enters the water storage tank 76 inside the outer shell 71 through the water inlet 58 via the water inlet 27 and the water outlet 28. After water enters the water storage tank 76, the overall weight of the cleaning mechanism 7 increases. Under the action of gravity, the entire cleaning mechanism 7 slides downward along the cleaning chute 59. The side block 72 compresses the seventh spring 73, and the outer shell 71 slides during the process. In the process, the cleaning belt 79 is always in contact with the surface of the solar panel 55, and the friction causes the cleaning belt 79 to rotate around the roller 78; the water outlet at the bottom of the water storage tank 76 releases water, which wets the cleaning belt 79 and also rinses the textured cylinder 75, making the cleaning belt 79 more effective when wet; the cleaning gears 74 on both sides of the outer shell 71 cooperate with the rotating rack 591 to drive the textured cylinder 75 to rotate, and the textured cylinder 75 scrapes and washes the surface of the cleaning belt 79. With the rinsing of water, the dirt is quickly removed, ensuring that the cleaning belt 79 and the textured cylinder 75 are clean. After the cleaning mechanism 7 slides to the bottom of the cleaning trough 59, the water in the water distribution chamber 24 and the remaining water in the water storage tank 76 are gradually consumed. Then the overall weight of the cleaning mechanism 7 is restored, and the seventh spring 73 pushes the cleaning mechanism 7 to reset. During the upward movement, the cleaning belt 79 wipes the solar panel 55 again to remove water stains from the surface of the solar panel 55 and improve the cleaning effect. Moreover, the cleaning gear 74 and the rotating rack 591 cooperate again to drive the textured cylinder 75 to reverse and squeeze the water on the cleaning belt 79, thereby reducing the water residue on the cleaning belt 79.
