[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a curved photovoltaic module. Background Technology

[0002] With the booming development of the new energy industry, photovoltaic modules, as key equipment for solar energy utilization, are increasingly widely used. Traditional planar photovoltaic modules suffer from problems such as low space utilization and limited adaptability to installation environments during installation and use. Curved photovoltaic modules, with their unique structure, can better adapt to different installation scenarios and improve space utilization. However, existing curved photovoltaic modules lack effective protective devices and are easily damaged under harsh weather conditions.

[0003] Therefore, developing a curved photovoltaic module with good protection performance, high energy collection efficiency and stable structure is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to provide a curved photovoltaic module to solve the problems of low light utilization, insufficient protection, and inconvenient cleaning of existing photovoltaic modules.

[0008] A curved photovoltaic panel, wherein the curved photovoltaic panel is disposed on the outer surface of the housing;

[0009] A protective cover, which is movably connected to both sides of the housing via a shaft;

[0010] The protective cover has an unfolded state and a closed state. In the unfolded state, it unfolds outward to expose the curved photovoltaic panel, and in the closed state, it closes inward to completely cover the curved photovoltaic panel.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0042] Below, please refer to the appendix. Figure 1-3 This invention describes a curved photovoltaic module, which includes:

[0043] Base 1; Base 1 can be made of metal or alloy materials, such as heavy steel structure or high-strength alloy material casting; the bottom of base 1 can be equipped with height-adjustable anchor bolts to adapt to the flatness requirements of different installation sites. The shape of base 1 can be a rectangular block, and its length and width are adapted to the size of box 2 to ensure that box 2 can be stably installed on its top.

[0044] The enclosure 2 is fixedly installed on the top of the base 1, for example, by bolts. A sealing gasket is placed between the two to prevent rainwater or other liquids from seeping into the connection. The enclosure 2 is made of corrosion-resistant stainless steel or other corrosion-resistant materials to adapt to different outdoor environments.

[0045] In one alternative embodiment, the tank 2 is a water storage tank, with an internal water storage chamber. The water storage chamber can be used to store rainwater or other water sources. The inner wall of the water storage chamber is treated with anti-corrosion measures to extend the service life of the tank 2.

[0046] In some alternative configurations, the water tank has a water inlet 8 on its top, equipped with a sealing cap to prevent debris from entering the water storage chamber. A water replenishment interface is located on the side of the water tank 2, and can use standard pipe interface specifications for easy connection to an external water supply pipe. When the water level in the storage chamber is insufficient, water can be replenished through the external water supply pipe.

[0047] In some optional designs, the housing 2 is a circular arc cylindrical structure with a central angle of cross-section satisfying the following condition: 180° ≤ central angle < 300°. For example, the central angle can be 180°, 185°, 190°, 195°, 200°, 205°, 210°, 211°, 212°, 215°, 220°, 225°, 230°, 235°, 240°, 245°, 250°, 255°, 260°, 265°, 270°, 275°, 280°, 285°, 290°, 295°, or 299°. This structure provides a larger installation area for the curved photovoltaic panel 4 while ensuring sufficient structural strength for the housing 2 to remain stable on the base. It is worth noting that the central angle of cross-section is the angle between two radii with the center of the circle containing the arc as the vertex. For example, as shown in the figure... Figure 3 As shown, the arc of the arc-shaped box is 3 / 4 of the entire circumference, so the central angle of the cross-section is 270°.

[0048] In some optional configurations, the coverage angle of the curved photovoltaic panel 4 extending along the arc surface of the housing 2 satisfies: 180° ≤ coverage angle ≤ 280°. The coverage angle can be, for example, 180°, 185°, 190°, 195°, 200°, 205°, 210°, 211°, 212°, 215°, 220°, 225°, 230°, 235°, 240°, 245°, 250°, 255°, 260°, 265°, 270°, 275°, or 280°. This maximizes the utilization of the outer surface of the housing 2, increases the area of ​​the curved photovoltaic panel 4 that receives sunlight, and improves power generation efficiency. It is worth noting that the coverage angle is the angle between two radii with the center of the circle containing the arc as the vertex, for example... Figure 3 As shown, the arc of the curved photovoltaic panel covering the arc-shaped box is 1 / 2 of the entire circumference, so the central angle of the cross-section is 180°.

[0049] Optionally, the curved photovoltaic panel 4 is attached to the outer surface of the housing 2 using a special photovoltaic adhesive. The photovoltaic adhesive has good bonding strength and weather resistance, which can ensure that the curved photovoltaic panel 4 is tightly attached to the housing 2 and is not easy to fall off.

[0050] Optionally, the curved photovoltaic panel 4 can be a crystalline silicon photovoltaic module or a thin-film photovoltaic module.

[0051] In some alternative configurations, the protective cover 3 is formed by combining arc-shaped plates on both sides of the base, the shape of which matches the outer contour of the housing 2. The protective cover 3 can be made of lightweight aluminum or fiberglass, which is lightweight and high-strength. The protective cover 3 is movably connected to both sides of the housing 2 via shafts 5. In the unfolded state, the protective cover 3 unfolds outward, which can fully expose the curved photovoltaic panel 4, allowing it to fully receive sunlight. In the closed state, the protective cover 3 closes inward, which can completely cover the curved photovoltaic panel 4, providing protection against dust, rain, and impact.

[0052] In some alternative configurations, the inner surface of the shield 3 is provided with a reflective layer, which is positioned facing the curved photovoltaic panel 4. Thus, when sunlight shines on the inner surface of the shield 3, the reflective layer can reflect some of the sunlight onto the curved photovoltaic panel 4, increasing the amount of light received by the curved photovoltaic panel 4.

[0053] In some alternatives, the reflective layer can be a polished metal plate or a coated reflective plate. For example, a polished aluminum plate with an anodized surface can be used as the substrate, providing not only good reflectivity but also high corrosion and wear resistance. Alternatively, a coated reflective plate, such as a silver-plated one, can be used, with a highly reflective metallic film on its surface, achieving similarly good reflective properties.

[0054] In some alternative configurations, the two ends of the shaft 5 are rotatably connected to the housing 2 via bearing seats, and the base of the protective cover 3 is fixedly sleeved on the shaft 5.

[0055] Specifically, the shaft 5 can be made of high-strength alloy steel, and its two ends are rotatably connected to the housing 2 through bearing seats. Deep groove ball bearings are installed in the bearing seats, which can reduce the friction when the shaft 5 rotates, making the opening and closing of the cover 3 smoother. The root of the cover 3 is fixedly sleeved on the shaft 5 by welding, ensuring that the cover 3 and the shaft 5 rotate synchronously.

[0056] In some alternative methods, such as Figure 4-5 As shown, the curved photovoltaic module also includes a drive mechanism, which includes a drive motor 7 and a transmission assembly. The drive motor is fixedly installed on the base 1; the transmission assembly connects the output shaft of the drive motor 7 to the end of the shaft 5.

[0057] Specifically, the drive motor 7 in the drive mechanism can be a DC geared motor. The drive motor 7 is fixedly installed on the base 1, for example, by bolts. The output shaft of the motor is connected to the transmission assembly through a coupling.

[0058] In some alternative configurations, the transmission mechanism includes a gearbox 6, a transmission rod, a driving bevel gear, a follower bevel gear, a transmission crown gear, and a driving gear; the gearbox 6 is fixed to the base 1; the transmission rod 10 is laterally mounted inside the gearbox 6 via bearings; the driving bevel gear 13 is fixed to both ends of the transmission rod 10; the follower bevel gear 11 is fixed to the end of the shaft 5 and meshes with the driving bevel gear 13; the transmission crown gear 12 is fixed to the middle of the transmission rod 10; and the driving gear 9 is mounted on the output shaft of the drive motor 7 and meshes with the transmission crown gear 12.

[0059] Specifically, the gearbox 6 can be made of corrosion-resistant metal or alloy materials; for example, it can be cast from cast iron and has multiple reinforcing ribs inside to improve the structural strength of the gearbox 6. The gearbox 6 is fixed to the base 1 by bolts, providing stable support for the various gears and transmission rods in the transmission assembly. The two ends of the transmission rod 10 are laterally positioned inside the gearbox 6 by bearings, such as tapered roller bearings, which can withstand large radial and axial loads. The driving bevel gear 13 is fixed to both ends of the transmission rod 10, and the following bevel gear 11 is fixed to the end of the shaft 5. The two mesh with each other and can transmit the rotational motion of the transmission rod 10 to the shaft 5. The transmission crown gear 12 and the driving gear 9 are both spur gears. The transmission crown gear 12 is fixed in the middle of the transmission rod 10, and the driving gear 9 is set on the output shaft of the drive motor 7. The two mesh with each other and can transmit the power of the drive motor 7 to the transmission rod 10.

[0060] The curved photovoltaic module provided according to this utility model is described in detail below with reference to several specific embodiments. It is worth understanding that the following description is merely illustrative and not intended to limit the invention. Example 1

[0061] like Figures 1 to 3 As shown, a curved photovoltaic module includes:

[0062] Base 1; the shape of base 1 can be a rectangular block structure;

[0063] A box 2 is mounted on top of the base 1; the box 2 is a water storage tank, which forms a water storage chamber inside. The box 2 has a water inlet 8 on the top and is equipped with a sealing cover. The box 2 has a circular arc cylindrical structure design, and its cross-sectional central angle α is 270°.

[0064] The curved photovoltaic panel 4 is disposed on the outer surface of the housing 2; the covering angle of the curved photovoltaic panel 4 extending along the arc surface of the housing 2 is β, and β is 180°.

[0065] A protective cover 3 is provided on the outer side of the curved photovoltaic panel 4. The protective cover 3 is an arc-shaped plate and is movably connected to both sides of the housing 2 via a shaft 5. The protective cover 3 has an unfolded state and a closed state. In the unfolded state, it unfolds outward to expose the curved photovoltaic panel 4, and in the closed state, it closes inward to completely cover the curved photovoltaic panel 4. A reflective layer is provided on the inner surface of the protective cover 3, facing the curved photovoltaic panel 4. The reflective layer is a polished aluminum plate. Example 2

[0066] like Figure 4-5 As shown, the curved photovoltaic module also includes a drive mechanism and a transmission mechanism; the drive motor is fixedly installed on the base 1; the transmission component connects the output shaft of the drive motor 7 to the end of the shaft 5.

[0067] The transmission mechanism includes a gearbox 6, a transmission rod, a driving bevel gear, a follower bevel gear, a transmission crown gear, and a driving gear; the gearbox 6 is fixed on the base 1; the transmission rod 10 is horizontally arranged in the gearbox 6 through bearings; the driving bevel gear 13 is fixed at both ends of the transmission rod 10; the follower bevel gear 11 is fixed at the end of the shaft 5 and meshes with the driving bevel gear 13; the transmission crown gear 12 is fixed in the middle of the transmission rod 10; the driving gear 9 is arranged on the output shaft of the drive motor 7 and meshes with the transmission crown gear 12.

[0068] The gearbox 6 is bolted to the base 1, providing stable support for the various gears and transmission rods in the transmission assembly. The two ends of the transmission rod 10 are laterally mounted within the gearbox 6 via bearings. The driving bevel gear 13 is fixed to both ends of the transmission rod 10, and the following bevel gear 11 is fixed to the end of the shaft 5. The two mesh with each other, transmitting the rotational motion of the transmission rod 10 to the shaft 5. Both the transmission crown gear 12 and the driving gear 9 are spur gears. The transmission crown gear 12 is fixed to the middle of the transmission rod 10, and the driving gear 9 is mounted on the output shaft of the drive motor 7. The two mesh with each other, transmitting the power of the drive motor 7 to the transmission rod 10.

[0069] Therefore, when the weather is sunny or rainless, the drive motor 7 is stationary, and the reflector 3 is open under the support of the shaft 5. At this time, the metal reflective surface inside the reflector 3 reflects the oblique sunlight from the surrounding environment onto the curved photovoltaic panel 4 installed on the water storage tank 2, increasing the light-receiving area and light intensity of the photovoltaic panel, and significantly improving the photoelectric conversion efficiency. When the weather monitoring system detects that heavy rain is imminent, it controls the drive motor 7 to start. The power output shaft of the drive motor 7 drives the drive gear 9 to rotate. The drive gear 9 meshes with the transmission crown gear 12, causing the transmission rod 10 to start rotating. The drive bevel gears 13 at both ends of the transmission rod 10 rotate accordingly. Through meshing with the follower bevel gear 11, they drive the shaft 5 to rotate, thereby causing the reflector 3 to close around the shaft 5, tightly covering the curved photovoltaic panel 4, providing protection for the photovoltaic panel, avoiding damage from heavy rain, and ensuring the stable operation of the photovoltaic module under severe weather conditions.
