Description

[0001] This application is a divisional application of application filed on October 9, 2025, with application number 2025114330768 and invention title "A Solar Photovoltaic Module That Is Easy to Clean". Technical Field

[0002] This invention relates to the field of photovoltaic power generation technology, and more specifically, to a modular solar photovoltaic module that is easy to clean. Background Technology

[0003] With the rapid development of solar photovoltaic (PV) power generation technology, solar PV modules, as an important application of clean energy, have been widely deployed in various environments. To improve the efficiency of PV power generation systems and extend their lifespan, surface cleaning of solar PV modules has become a crucial step. However, existing solar PV modules face many challenges in practical applications, particularly in surface cleaning.

[0004] First, solar photovoltaic (PV) modules are often exposed to the natural environment for extended periods, especially in arid, dusty, or seasonally rainy areas. Pollutants such as dust, sand, bird droppings, and leaves easily adhere to the surface of PV modules, obstructing sunlight and significantly reducing their energy conversion efficiency. Furthermore, in harsh weather conditions, such as rain or snow, the surface of PV modules may become covered with water or ice, which not only affects power generation efficiency but also accelerates the aging and damage of the PV equipment, reducing its lifespan.

[0005] Secondly, since most photovoltaic modules are fixedly installed, cleaning work usually requires specialized equipment or personnel to perform high-altitude operations, which is both time-consuming and poses certain safety risks. Especially when the photovoltaic array covers a large area, the cleaning work becomes more cumbersome and less efficient, making it difficult to achieve regular and comprehensive maintenance. Summary of the Invention

[0014] In a preferred embodiment of the present invention, a plurality of propulsion mechanisms are installed inside the sub-beam.

Splicing grooves are provided on both sides of the splicing block, and the connector is engaged in the corresponding splicing groove.

[0015] Compared with the prior art, the advantages of this invention are: The solar photovoltaic modules adopt a modular design. When stored, each rotating motor independently controls one power generation mechanism to rotate 90 degrees. A propulsion mechanism gathers all power generation mechanisms in the same row together for folding. This reduces exposed area, preventing damage to the photovoltaic equipment from severe weather, and also reduces space occupation and shading of the photovoltaic panels. When adjacent power generation mechanisms collide, the connecting block on the front frame inserts into the connecting hole on the rear frame. The connecting block engages with the locking block through a locking groove, combining the two adjacent power generation mechanisms. Simultaneously, the connecting block pushes the blocking block to move, releasing the restriction on the anti-rotation plate and allowing the shaft and display plate to rotate freely. During the resetting process of several power generation mechanisms, when the display plate collidees with each stop column, the display plate can swing freely to avoid the stop column, preventing power generation mechanisms that should not stop from being blocked by the stop column.

[0016] As several power generation mechanisms enter the storage mechanism, the front rotating motor drives the push plate to slide, which in turn causes one storage rack to drive another storage rack to slide through the rotating gear. This, in turn, causes the folding awning to unfold, covering all the power generation mechanisms and protecting them from rain and snow erosion. This slows down the damage and aging of the power generation mechanisms and extends their service life.

[0017] When several power generation units enter the housing, the water inlets on all the top frames connect with the corresponding water outlets on the water inlet rods. During the sliding process of the push plate, the push rods slide, controlling the sealing plugs to block the water outlets and the sliding of the on / off plates, thus connecting the water inlet chamber with the water outlet. Water from the water inlet chamber enters the water storage tank. After being filled with water by the cleaning mechanism, the increased weight causes the water to slide downwards automatically, thus cleaning the surface of the solar panels and removing dust and dirt. During the cleaning process, the rotating textured cylinder squeezes the cleaning belt, scraping away dirt. Simultaneously, the water storage tank releases water to rinse the cleaning belt and textured cylinder, quickly removing dirt. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0021] Please see Figure 1-18 As shown, the present invention discloses a modular solar photovoltaic module that is easy to clean, including a frame mechanism 1. The frame mechanism 1 includes a main beam 11. Two side beams 12 are installed on both ends of the main beam 11. Several middle beams 13 are installed at equal intervals between the two side beams 12. A secondary beam 16 is installed at the other end of the side beams 12 and the middle beams 13. Side rods 14 are fixed at the bottom of the side beams 12 and the middle beams 13. Several stop columns 15 are fixed on the top surface of the side rods 14. Storage grooves 17 are provided on the inner side of the side beams 12 and the two sides of the middle beams 13. A water collection mechanism 2 is installed on the top surface of the main beam 11. The water collection mechanism 2 includes a support column 21, which is fixed to the top surface of the main beam 11. A water collection tank 22 is installed on the top of the support column 21. The water collection tank 22 has several water distribution chambers 24 inside and several water injection rods 26 on the side of the water collection tank 22. A power generation mechanism 5 slides inside the storage slide 17. The power generation mechanism 5 includes a rotary motor 51, which is slidably connected inside the storage slide 17. The output end of the rotary motor 51 is connected to a frame 52. The two ends of the top frame 53 and the bottom frame 54 are respectively fixedly connected to the two ends of the two frames 52. A solar panel 55 is installed in the space enclosed by the frame 52, the top frame 53 and the bottom frame 54. A storage groove 56 is provided on the frame 52. An unfolding mechanism 6 is installed inside the storage slot 56. The unfolding mechanism 6 includes a rotating shaft 61, which is rotatably connected to the storage slot 56 via a torsion spring. A blocking strip 62 and an unfolding plate 63 are fixed on the surface of the rotating shaft 61. The unfolding plate 63 is engaged with the inside of the storage slot 56. An anti-rotation plate 66 is slidably connected inside the frame 52, and the blocking strip 62 abuts against the anti-rotation plate 66. Two blocking blocks 67 are also symmetrically slidably connected inside the frame 52, and the two blocking blocks 67 abut against the anti-rotation plate 66. A cleaning mechanism 7 is installed inside the top frame 53. The cleaning mechanism 7 includes a housing 71. A water storage tank 76 is provided inside the housing 71, and the bottom of the water storage tank 76 has an opening. A cleaning belt 79 and a textured cylinder 75 are rotatably connected inside the housing 71, and the textured cylinder 75 abuts against the cleaning belt 79.

[0022] Furthermore, the solar photovoltaic modules adopt a modular design, with each power generation mechanism 5 individually controlled by a rotating motor 51. In adverse weather conditions such as cloudy, rainy, or snowy days, the solar photovoltaic modules can be selectively recycled. During recycling, the rotating motor 51 first drives the power generation mechanism 5 to rotate 90 degrees (according to the attached diagram). Figure 1 (Rotating counterclockwise) to erect the power generation mechanism 5. Then, the push motor 81 inside the secondary beam 16 starts, sliding into the receiving grooves 17 on the side beam 12 and the middle beam 13, causing the docking slider 82 to connect with its nearest power generation mechanism 5 (according to the attached...). Figure 1The generator 5 closest to the main beam 11 is called the front generator 5, and the generator 5 closest to the secondary beam 16 is called the end generator 5 (the same applies below). The drive motor 81 drives the end generator 5 to slide between the side beam 12 or the middle beam 13 through the docking slider 82, so that several generators 5 collide with each other in sequence and slide together towards the main beam 11. When two adjacent generators 5 collide with each other, they are engaged by the locking groove 693 on the front frame 52 and the locking block 691 in the rear frame 52. When the rear generator 5 drives the front generator 5 to slide together for a certain distance, the rotating motor 51 in the front generator 5 triggers the storage mechanism 3, so that the folding awning 36 unfolds and protects all the generators 5 gathered on the side of the main beam 11 from rain and snow erosion.

[0023] During long-term power generation, dust accumulates on the surface of the solar panel 55, reducing its light conversion efficiency. To ensure the light conversion efficiency of the solar panel 55, it is necessary to clean it. Therefore, after the storage mechanism 3 is triggered for a certain period of time, the water inlet 58 on each top frame 53 is connected to the water outlet 28 on the water inlet rod 26. At the same time, the storage mechanism 3 drives the switching mechanism 4 to move, causing the water outlet 25 to close and the water outlet 28 to open. 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, its weight increases. The seventh spring 73 can no longer support the weight of the cleaning mechanism 7, and the cleaning mechanism 7 slides down the cleaning chute 59 under the action of gravity. During this process, the water storage tank 76 sprays water to wet the cleaning belt 79, and the cleaning belt 79 comes into contact with the solar panel 55 to clean it. Example

[0024] This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1-18 A storage mechanism 3 is installed on the top surface of the side beam 12. The storage mechanism 3 includes a rotating gear 31, which is rotatably connected to the inside of one end of the side beam 12. Two storage racks 32 are simultaneously engaged with the rotating gear 31. A push plate 33 is fixed to the side of one of the storage racks 32. The push plate 33 is slidably connected to the storage groove 17, and the rotating motor 51 abuts against the push plate 33. A first spring 34 is installed at the end of the storage rack 32. A folding canopy 36 is fixed to the top surface of one end of the frame 52. Several stabilizing sliders 35 are fixed to the bottom end of the folding canopy 36, and one of the stabilizing sliders 35 is fixed to the top surface of the other storage rack 32.

[0025] The end of the display panel 63 is fixed with a protruding strip 64. The bottom surfaces of the side beam 12 and the middle beam 13 are provided with several grooves that cooperate with the protruding strip 64 at equal intervals. A fourth spring 65 is installed inside the frame 52, and the fourth spring 65 abuts against the anti-rotation plate 66. A fifth spring 68 is also installed inside the frame 52, and the fifth spring 68 abuts against the blocking block 67. A sixth spring 69 is installed in the connecting hole 57. A locking block 691 is slidably connected in the connecting hole 57, and one end of the sixth spring 69 abuts against the locking block 691. Two connecting blocks 692 are symmetrically fixed on the side of the frame 52, and the connecting blocks 692 are slidably 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 engaged with the locking groove 693.

[0026] Several propulsion mechanisms 8 are installed inside the sub-beam 16. Each propulsion mechanism 8 includes a push motor 81, which is installed inside the sub-beam 16 and slidably connected to a corresponding storage groove 17. A docking slider 82 is installed on the side of the push motor 81. The docking slider 82 has a docking groove 83 inside. An eighth spring 85 is symmetrically installed inside the docking slider 82. A connector 84 is symmetrically slidably connected in the docking groove 83, and one end of the eighth spring 85 is installed on the connector 84. A splicing block 86 is fixed to the side of one of the frame 52 and slidably connected in the docking groove 83. Splicing grooves 87 are provided on both sides of the splicing block 86, and the connector 84 is engaged in the corresponding splicing groove 87.

[0027] Furthermore, after the rotating motor 51 drives the power generation mechanism 5 to rotate 90 degrees, the frame 52 becomes vertical, and the display panel 63 is no longer restricted by the side beam 12 or the middle beam 13. The torsion spring drives the rotating shaft 61 to rotate 90 degrees, and the blocking strip 62 fixed on the rotating shaft 61 and the display panel 63 rotate together (after rotating 90 degrees, the display panel 63 is perpendicular to the surface of the frame 52). Subsequently, the push motor 81 in the secondary beam 16 starts and slides into the storage groove 17 on the side beam 12 and the middle beam 13, and drives the docking slider 82 to move together. When the docking slider 82 touches the end frame 52, the splicing block 86 fixed on the end frame 52 inserts into the docking groove 83 in the docking slider 82. At the same time, the eighth spring 85 in the docking slider 82 pushes the connector 84 to insert into the splicing groove 87, so that the splicing block 86 and the docking slider 82 are connected as a whole. The push motor 81 pushes the end power generation mechanism 5 closer to the main beam 11 through the docking slider 82, and the rotating motor 51 on the side of the end frame 52 also slides in the storage groove 17. As the end power generation mechanism 5 moves, it will sequentially come into contact with the previous power generation mechanism 5, until all power generation mechanisms 5 come into contact with each other and move closer to the main beam 11. During the sliding of the power generation mechanism 5 along the receiving chute 17, the display plate 63 contacts the stop post 15 on the side rod 14. Since the display plate 63 can rotate to the right via the pivot 61 (see attached diagram),... Figure 15 Therefore, the stop column 15 will not prevent the power generation mechanism 5 from moving through the display panel 63.

[0028] When the rear power generation mechanism 5 abuts against and drives the front power generation mechanism 5 to slide, the rotating motor 51 inside the front power generation mechanism 5 abuts against the push plate 33 in the receiving slide groove 17. The push plate 33 drives the stabilizing slider 35, which is fixedly connected to the receiving rack 32, to slide through the cooperation of the receiving rack 32 and the rotating gear 31. (The folding awning 36 is composed of several U-shaped rods and canvas. Each U-shaped rod has a stabilizing slider 35 installed at its bottom end. The stabilizing slider 35 at the front end is fixed to the side beam 12, and the stabilizing slider 35 at the rear end is fixed to one of the receiving racks 32. The other stabilizing sliders 35 slide in the slide groove opened on the top surface of the side beam 12. See attached figure.) Figure 3 The direction closer to the main beam 11 is called the head end, and the direction farther away from the main beam 11 is called the tail end. The stabilizing slider 35, which follows the sliding of the rack 32, drives the folding canopy 36 to unfold, protecting all the power generation mechanisms 5 from wind and snow erosion.

[0029] During the mutual contact of adjacent power generation mechanisms 5, the connecting block 692 on the front frame 52 will insert into the connecting hole 57 on the rear frame 52. The locking block 691 in the connecting hole 57 will insert into the locking groove 693 on the connecting block 692, so that the two adjacent power generation mechanisms 5 are joined together (the resistance between the locking groove 693 and the locking block 691 is less than the resistance between the stop column 15 and the display plate 63). At the same time as the connecting block 692 is inserted into the connecting hole 57, it will also push the two blocking blocks 67 to slide up and down respectively (according to the attached...). Figure 15 (The direction), release the restriction of the anti-rotation plate 66, thereby releasing the restriction of the anti-rotation plate 66 on the blocking strip 62, allowing the rotating shaft 61 to rotate freely, and the display plate 63 to swing left and right (see appendix). 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, thus abutting the blocking strip 62, preventing the rotating shaft 61 from rotating to the left, and the display plate 63 can only rotate to the right with the rotating shaft 61. When several power generation mechanisms 5 are deployed, the propulsion mechanism 8 pulls the end power generation mechanisms 5 back to their initial positions one by one. (See attached...) Figure 18As 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. Example

[0030] This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1-18 The top of the water collection tank 22 is equipped with a cover plate 23, which has an inverted "V" shaped structure. Each water distribution chamber 24 has a water distribution port 25 at its top. The bottom surface of the water injection rod 26 is provided with several water outlets 28. The inside of the water injection rod 26 is provided with a water injection cavity 27, and the water injection cavity 27 is connected to the corresponding water distribution chamber 24 and water outlet 28 respectively.

[0031] The main beam 11 is equipped with a switching mechanism 4, which includes a push column 41. The push column 41 is slidably connected inside the main beam 11, with one end of the push column 41 located within the receiving groove 17. A push plate 33 abuts against the push column 41. A second spring 42 is sleeved on the push column 41. A relay rod 43 is fixed to the push column 41, and a connecting rod 44 is fixed to the top of the relay rod 43. The connecting rod 44 is slidably connected within the water injection rod 26. Several switching plates 45 are equidistantly fixed to the connecting rod 44. Several through-plates 45 respectively abut against the drain outlet 28. The end of the push column 41 is fixed with a squeezing wedge 46. The main beam 11 is installed with a lifting wedge 47, and the squeezing wedge 46 abuts against the lifting wedge 47. The top surface of the lifting wedge 47 is fixed with a lifting rod 48, and the lifting rod 48 is slidably connected to the inside of the support column 21. A third spring 49 is sleeved on the lifting rod 48. The top end of the lifting rod 48 is fixed with a sealing plug 491, and the sealing plug 491 is engaged and connected to the drain outlet 25.

[0032] The side of the frame 52 is provided with a connecting hole 57, and the top surface of the top frame 53 is provided with two water inlets 58 symmetrically, and the water inlets 58 are connected to the drain outlet 28. The inner side of the frame 52 is provided with a cleaning chute 59, and the inside of the cleaning chute 59 is provided with a rotating rack 591.

[0033] Side blocks 72 are fixed on both sides of the outer casing 71. The side blocks 72 are slidably connected to the cleaning trough 59. A seventh spring 73 is installed in the cleaning trough 59. The side blocks 72 abut against the seventh spring 73. The two ends of the textured cylinder 75 pass through the side of the outer casing 71 and are fixedly connected to the cleaning gear 74. The cleaning gear 74 is slidably connected to the cleaning trough 59 and is meshed with the rotating rack 591. The side of the outer casing 71 is provided with a water inlet 77, and the water inlet 77 is connected to the water inlet 58 through a hose. Two rollers 78 are rotatably connected inside the outer casing 71. A cleaning belt 79 is rotatably connected to the surface of the two rollers 78 and abuts against the solar panel 55.

[0034] 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.
