[0040] Figure 3 It is a schematic diagram of the arrangement of the protective cloth 2 and the rotating shaft according to some embodiments of the present application.

[0041] One or more embodiments of the present application disclose a photovoltaic module protection device. Figure 1 , 2 3. The photovoltaic module protection device includes a mounting frame assembly 1, a protective cloth 2 and a transparent film 3; the protective cloth 2 is movably arranged on the mounting frame assembly 1, the protective cloth 2 is arranged on the periphery of the photovoltaic module 4 and is provided with a mounting port 21; the transparent film 3 is arranged at the mounting port 21, and the transparent film 3 is used to cover the illuminated surface of the photovoltaic module 4.

[0042] In this embodiment, the installation opening 21 is a through opening designed on the protective cloth 2 , that is, the installation opening 21 penetrates the protective cloth 2 .

[0043] In this embodiment, the transparent film 3 can be installed at the installation opening 21 in an irremovable manner, such as by gluing, or the transparent film 3 can be installed at the installation opening 21 in a removable manner, such as by gluing with Velcro. There is no limitation here, and it depends on actual needs.

[0044] By adopting the above technical solution, after the protective cloth 2 is set on the mounting frame assembly 1, it is arranged on the periphery of the photovoltaic assembly 4, that is, the protective cloth 2 is arranged around the outside of the photovoltaic assembly 4, rather than directly contacting the surface of the photovoltaic assembly 4; the reserved mounting port 21 design on the protective cloth 2 provides a channel for convenient loading and unloading of the transparent film 3, so that the transparent film 3 can be easily covered on the illuminated surface of the photovoltaic assembly 4, while ensuring that light is unobstructed, which not only protects the illuminated surface of the photovoltaic assembly 4 from dust, fallen leaves, bird droppings and other debris, but also does not need to worry about shading affecting the light energy absorption efficiency, and when the impurities accumulated on the transparent film 3 reach a certain amount, by operating the protective cloth 2 to move, the protective cloth 2 and the transparent film 3 can be moved to a state that is convenient for cleaning the debris, thereby facilitating the cleaning of the protective cloth 2 and the transparent film 3.

[0045] At the same time, the design of the protective cloth 2 plus the transparent film 3 can effectively reduce the direct contact between the transparent film 3 and the mounting frame assembly 1, thereby reducing the wear during the movement, compared with directly moving the transparent film 3.

[0046] In some embodiments, the protective cloth 2 is arranged in a ring shape to form a receiving groove for receiving the photovoltaic component 4 .

[0047] In at least one embodiment, reference Figure 1 , 2 After the protective cloth 2 is installed on the mounting frame assembly 1, it is arranged in a ring shape as a whole, and a receiving groove for accommodating the photovoltaic component 4 is formed inside it. That is to say, the photovoltaic component 4 is located inside the protective cloth 2. At this time, part of the inner wall of the protective cloth 2 faces the illuminated surface of the photovoltaic component 4, and part of the inner wall of the protective cloth 2 faces the bottom surface of the photovoltaic component 4.

[0048] In this way, the annular protective cloth 2 can provide a more comprehensive protection for the photovoltaic module 4, covering the illuminated surface and bottom surface of the photovoltaic module 4, effectively isolating dust, rain, bird droppings, fallen leaves and other debris, reducing direct impact and accumulation, and protecting the photovoltaic module 4 from damage.

[0049] In some embodiments, a plurality of mounting openings 21 are provided, and the plurality of mounting openings 21 are arranged around the photovoltaic component 4 .

[0050] In at least one embodiment, two mounting openings 21 are provided, and the two mounting openings 21 are symmetrically arranged on the protective cloth 2; when one mounting opening 21 faces the illuminated surface of the photovoltaic component 4, the other mounting opening 21 faces the bottom surface of the photovoltaic component 4. In this way, the transparent film 3 at the two mounting openings 21 can be recycled, thereby reducing the number of times the protective cloth 2 is moved, and further reducing the loss of the protective cloth 2 caused by movement.

[0051] In other embodiments, the number of the mounting opening 21 may also be one. In this way, when it is necessary to clean the debris on the transparent film 3, the corresponding mounting opening 21 may be pulled toward the bottom surface of the photovoltaic module 4 to clean the debris on the transparent film 3; after cleaning, the mounting opening 21 may be pulled toward the illuminated surface of the photovoltaic module 4, and at this time, the transparent film 3 covers the illuminated surface of the photovoltaic module 4.

[0052] In some embodiments, the protective cloth 2 is driven by an external force to perform a circular motion along the photovoltaic assembly 4 .

[0053] In this embodiment, the movement of the protective cloth 2 can be performed manually or electrically, without limitation, depending on actual needs.

[0054] In this way, by operating the movement of the protective cloth 2, the positional relationship between the transparent film 3 and the illuminated surface of the photovoltaic module 4 can be changed, so as to adapt to different environments. For example, during the day, the transparent film 3 can be covered on the photovoltaic surface of the photovoltaic module 4, so that the photovoltaic module 4 can absorb light energy normally; at night, the protective cloth 2 can be caused to make a circular movement relative to the photovoltaic module 4, so that the protective cloth 2 covers the photovoltaic surface of the photovoltaic module 4. At this time, the transparent film 3 follows the protective cloth 2 to move to the bottom of the photovoltaic module 4, and some debris will fall from the transparent film 3 under the action of gravity, which can reduce the dust on the transparent film 3 to a certain extent. Moreover, the protective performance of the protective cloth 2 is stronger than that of the transparent film 3, which is convenient for preventing flying stones or debris from hitting the photovoltaic module 4 in strong winds at night, thereby causing damage to the photovoltaic module 4.

[0055] On snowy days, too much snow is easily accumulated on the transparent film 3. When the transparent film 3 follows the protective cloth 2 in a circular movement, the accumulated snow can be quickly moved down, thereby improving the situation where the snow accumulates on the transparent film 3 for a long time and crushes the photovoltaic module 4.

[0056] In some embodiments, the mounting frame assembly 1 includes a first mounting frame 11 and a second mounting frame 12 which are arranged in parallel and at intervals. The first mounting frame 11 and the second mounting frame 12 are respectively fixedly connected to the opposite ends of the photovoltaic component 4, and the protective cloth 2 is at least partially located between the first mounting frame 11 and the second mounting frame 12.

[0057] In at least one embodiment, Figure 1 As shown, the first mounting frame 11 and the second mounting frame 12 are both rectangular structures, which are parallel and spaced apart and fixedly connected to the opposite ends of the photovoltaic module 4, respectively, and the connection methods include but are not limited to snap-on, plug-in or bonding, etc.; the protective cloth 2 is at least partially located between the first mounting frame 11 and the second mounting frame 12, wherein the protective cloth 2 at least partially refers to a part or all of the protective cloth 2; as shown Figure 1 , 2As shown in FIGS. 4 and 5 , part of the protective cloth 2 is disposed between the first mounting frame 11 and the second mounting frame 12 , and opposite ends of the protective cloth 2 are fixedly connected to the first mounting frame 11 and the second mounting frame 12 , respectively.

[0058] In this way, when the photovoltaic assembly 4 is driven by external force and vibrates, the first mounting frame 11 and the second mounting frame 12 are arranged at opposite ends of the photovoltaic assembly 4 in parallel and at intervals, which can effectively improve the uniform load-bearing capacity of the photovoltaic assembly 4, enhance the overall stability and wind and earthquake resistance, and prevent displacement. The protective cloth 2 is connected with the first mounting frame 11 and the second mounting frame 12 to form a protective layer surrounding the photovoltaic assembly 4, which can effectively isolate external debris such as rain, dust, fallen leaves, bird droppings and other debris.

[0059] In other embodiments, the first mounting bracket 11 and the second mounting bracket 12 may also be square or other irregular shapes, which are not limited here and depend on actual needs.

[0061] Further, refer to Figure 4 The bottom of the first mounting frame 11 and / or the second mounting frame 12 is supported by a support rod 8, so as to suspend the first mounting frame 11 and / or the second mounting frame 12. At the same time, when there are multiple photovoltaic modules 4, the adjacent first mounting frames 11 and second mounting frames 12 can share the support rod 8, thereby reducing the number of support rods 8 to save costs.

[0062] In some embodiments, the shape of the mounting opening 21 matches the shape of the photovoltaic component 4 .

[0063] It should be noted that, in this embodiment, the shape of the mounting opening 21 includes not only the shape but also the size. Meanwhile, the shape of the mounting opening 21 is adapted to the shape of the photovoltaic module 4, which means that the size of the mounting opening 21 is greater than or equal to the illuminated surface of the photovoltaic module 4.

[0071] In this way, when installing the protective cloth 2, one end of the protective cloth 2 can be first extended into the first shell 111 for fixation, and then the first cover plate 112 can be fixed to the first opening 1111 of the first shell 111, and one end of the protective cloth 2 can be located between the first cover plate 112 and the first opening 1111, thereby achieving the purpose of keeping one end of the protective cloth 2 open; finally, the same method is used to extend the other end of the protective cloth 2 into the second shell 121 for fixation, and the other end of the protective cloth 2 can be located between the second cover plate 122 and the second opening 1211, thereby achieving reliable installation of the protective cloth 2.

[0073] In this embodiment, the first shell 111 and the first cover plate 112, as well as the second shell 121 and the second cover plate 122 are connected by threaded rods, wherein the number of threaded rods is determined according to the length of the first cover plate 112 or the second cover plate 122, that is, when the length of the first cover plate 112 or the second cover plate 122 is longer, the number of corresponding threaded rods is greater; conversely, when the length of the first cover plate 112 or the second cover plate 122 is shorter, the number of corresponding threaded rods is less.

[0074] In some embodiments, a first annular groove structure 1112 is provided inside the first shell 111; a second annular groove structure 1212 is provided inside the second shell 121; a first annular protrusion 22 and a second annular protrusion 23 are respectively provided at the opposite ends of the protective cloth 2; the first annular protrusion 22 is arranged in the first annular groove structure 1112; the second annular protrusion 23 is arranged in the second annular groove structure 1212; the protective cloth 2 between the first annular protrusion 22 and the second annular protrusion 23 is in a stretched state.

[0084] In other embodiments, the first limiting plate 51 may be integrally formed with the first shell 111 or the second shell 121 or fixed by screws; similarly, the second limiting plate 52 may be integrally formed with the first cover plate 112 or the second cover plate 122 or fixed by screws.

[0085] In some embodiments, the photovoltaic module protection device also includes a power assembly, which includes a drive motor 6 and a plurality of rotating shafts 7. The plurality of rotating shafts 7 are respectively fitted with the protective cloth 2. At least one rotating shaft 7 is equipped with a drive motor 6. The drive motor 6 is used to drive the rotating shaft 7 to rotate relative to the first mounting frame 11 and the second mounting frame 12.

[0086] In at least one embodiment, the protective cloth 2 makes a circumferential motion relative to the photovoltaic assembly 4 through a power assembly, wherein the power assembly includes a drive motor 6 and four rotating shafts 7, and the four rotating shafts 7 are respectively supported at four corners inside the protective cloth 2, that is, the four rotating shafts 7 tighten the protective cloth 2 and realize transmission through static friction, one end of the rotating shaft 7 along the axial direction is rotatably connected to the first cover plate 112, and the other end of the rotating shaft 7 along the axial direction is rotatably connected to the second cover plate 122, and one of the rotating shafts 7 is equipped with a drive motor 6, and the drive motor 6 is used to drive the rotating shaft 7 to rotate relative to the first mounting frame 11 and the second mounting frame 12.

[0087] In this way, after the driving motor 6 is started, it can drive one of the rotating shafts 7 to rotate. Due to the static friction between the rotating shaft 7 and the protective cloth 2, the four rotating shafts 7 can drive the protective cloth 2 to move in a circular motion, thereby changing the positional relationship between the transparent film 3 and the illuminated surface of the photovoltaic component 4.

[0088] In this embodiment, the drive motor 6 can be arranged inside the first housing 111 or the second housing 121, and be connected to the rotating shaft 7 through a coupling; it can also be arranged outside the first housing 111 or the second housing 121, and be connected to the rotating shaft 7 through a helical gear transmission mechanism. There is no limitation here, and it depends on actual needs.

[0089] In other embodiments, each of the four rotating shafts 7 is equipped with a driving motor 6, and the four driving motors 6 work synchronously. In this way, when the four driving motors 6 synchronously drive the four rotating shafts 7 to rotate, the difficulty of moving the protective cloth 2 is greatly reduced compared with one driving motor 6.

[0090] Furthermore, a gear is provided on the rotating shaft 7, and a ring-shaped soft rack is provided on the protective cloth 2. The gear and the soft rack are meshed for transmission. Therefore, by increasing the friction between the rotating shaft 7 and the protective cloth 2, the slippage between the rotating shaft 7 and the protective cloth 2 can be effectively improved.

[0092] In this embodiment, the opposite ends of the photovoltaic component 4 are respectively connected to the first mounting frame 11 and the second mounting frame 12 of the mounting frame assembly 1 of the photovoltaic component protection device. The protective cloth 2 of the photovoltaic component protection device is arranged in a ring shape, and a receiving groove is formed inside it. The photovoltaic component 4 is located in the receiving groove.

[0093] The photovoltaic carport of this embodiment has the same beneficial effects as the above-mentioned photovoltaic component protection device relative to the prior art, so it will not be repeated here.
