Technical Field
[0001] This utility model relates to the field of photovoltaic panel technology, and more specifically, to a retractable photovoltaic panel module. Background Technology
[0002] With the continued growth of global demand for clean energy, photovoltaic (PV) power generation, as a sustainable and pollution-free energy source, has been widely applied and promoted. Coastal cities are typically densely populated and economically developed, with enormous energy demands. PV power generation, as a green and renewable energy solution, aligns with the strategic goals of sustainable development in coastal areas. However, PV panels in coastal cities are easily damaged during rainy and typhoon seasons. Therefore, we propose a retractable PV panel module. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a retractable photovoltaic panel module to solve the technical problem that photovoltaic panels in coastal areas are easily damaged by rainstorms and typhoons.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a retractable photovoltaic panel assembly, comprising three photovoltaic panels, with metal frames fixed to the outer edges of the three photovoltaic panels, and the three metal frames being rotatably connected to each other on one side. A cylinder is provided on the outer side of the middle metal frame, and an outer connecting plate is installed on the fixed end of the cylinder. The outer connecting plate has multiple threaded holes for external fixing. The driving end of the cylinder is provided with a storage structure. Both ends of the back side of the metal frame are provided with a surrounding structure, and a force-relieving structure is provided between two of the surrounding structures.
[0005] Preferably, the storage structure includes a connecting plate fixed to the cylinder drive end, a hollow head is installed on one side of the connecting plate, the hollow head has a hollow center, two connecting rods are hinged inside the hollow head, the connecting rods are respectively located at the positions of two metal frames on the side, and the ends of the connecting rods are movably connected to connecting pins, which are connected to the metal frames.
[0006] Preferably, the surrounding structure includes three side plates, which are fixed to a metal frame. A semi-circular ring is installed on one side of each side plate. The semi-circular ring is an arc shape of 10 degrees, and the three semi-circular rings form a complete ring.
[0007] Preferably, the ends of the middle semi-circular ring and the side semi-circular rings are hinged, and the ends of the two side semi-circular rings that are engaged are provided with a concave-convex structure for reinforcement and fixation. The ends of the two side semi-circular rings that are engaged are threadedly fixed with a fixing sleeve in the non-fixed state.
[0008] Preferably, the stress relief structure includes a sliding arc plate, which is an arc-shaped plate with a groove. The groove is adapted to the cross-section between the side plate and the semi-arc ring, and the sliding arc plate slides along the trajectory of the semi-arc ring.
[0009] Preferably, the pressure relief structure further includes two pressure relief vanes, the ends of which are fixed to one side of the sliding arc plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model utilizes a cylinder-driven storage structure, enabling the two metal frames on the sides to rotate the photovoltaic panel. Ultimately, the adjacent sides adhere tightly, forming a triangular structure that effectively surrounds the photovoltaic panel. This design reduces the risk of damage from external objects impacting the panel. Simultaneously, the triangular structure guides wind, preventing the photovoltaic panel from directly bearing wind force and protecting it from damage caused by strong winds. This enhances the safety of the photovoltaic panel in severe weather and addresses the problem of photovoltaic panels in coastal areas being easily damaged by heavy rain and typhoons.
[0012] 2. This utility model also utilizes the interaction between the surrounding structure and the stress-relief structure on the back side of the metal frame. During typhoons and heavy rain, the three semi-circular rings can rotate into a ring structure and be fixed by the interlocking structure. When a storm hits, the wind can blow the stress-relief rotor, causing the sliding arc plate to move along the ring formed by the semi-circular rings, thus achieving stress relief again. This design effectively reduces the impact of storms on photovoltaic panels, further improves the wind resistance of photovoltaic panel modules under extreme weather conditions, extends the service life of photovoltaic panels, and further solves the problem that photovoltaic panels in coastal areas are easily damaged by heavy rain and typhoons.
[0013] 3. This utility model addresses the issue that coastal cities have high energy demands, and photovoltaic power generation aligns with their sustainable development goals. This retractable photovoltaic panel module not only meets the energy needs of coastal cities but also features an innovative design that addresses the problem of photovoltaic panels being easily damaged during local rainstorm and typhoon seasons. This improves the adaptability and reliability of photovoltaic panels in special environments and provides strong support for the utilization of clean energy in coastal cities.

[0019] like Figures 1 to 4 As shown, the retractable photovoltaic panel module involved in this utility model is an innovative product carefully developed and designed for complex natural environments, especially in areas prone to storms. Its core purpose is to provide an effective protection mechanism for photovoltaic panels, ensuring stable operation under harsh weather conditions, extending service life, and optimizing energy harvesting efficiency.
[0020] The module mainly consists of three photovoltaic panels 1, which are made of high-efficiency monocrystalline silicon or polycrystalline silicon materials, possessing excellent photoelectric conversion efficiency and able to stably output power under different lighting conditions. Each photovoltaic panel 1 has a metal frame 2 fixed to its outer edge. The metal frame 2 is made of high-strength aluminum alloy, which not only has good corrosion resistance and can effectively resist natural erosion such as rain and sand, but also provides reliable mechanical support for the photovoltaic panel 1, ensuring its structural integrity in various environments. The back of the middle metal frame 2 is equipped with a frame made of stainless steel, which is firmly connected to the metal frame 2 by welding or bolting. The frame is then fixed to the outside, providing a stable installation base for the entire photovoltaic panel 1 module. The three metal frames 2 are connected to each other on adjacent sides by high-precision hinges. This connection method can ensure flexible rotation between the photovoltaic panels 1 and maintain a stable structure in use. A cylinder 3 is set on the outside of the middle metal frame 2. The cylinder 3 serves as the power source for the entire storage and protection mechanism, using high-performance pneumatic actuators with powerful thrust and precise control performance.
[0021] Storage and protection structure:
[0022] Storage Structure: To effectively protect the photovoltaic panel 1, an external connecting plate 4 is installed at the fixed end of the cylinder 3. The external connecting plate 4 is made of thick steel plate and has been galvanized to enhance its corrosion resistance. Multiple threaded holes are provided on the external connecting plate 4 for external fixing. High-strength bolts are used to securely connect the external connecting plate 4 to the external wall, bracket, or other objects. A storage structure 5 is provided at the drive end of the cylinder 3. The storage structure 5 includes a connecting plate 501 fixed to the drive end of the cylinder 3. The connecting plate 501 is made of high-strength alloy steel and is tightly connected to the drive end of the cylinder 3 through welding. A hollow head 502 is installed on one side of the connecting plate 501. The hollow head 502 is manufactured using precision casting and has a hollow center. Its internal space is used to install and accommodate related transmission components. Two connecting rods 503 are hinged inside the hollow head 502 via pins. The connecting rods 503 are made of lightweight and high-strength carbon fiber composite material, with a good strength-to-weight ratio. The cylinder 3 is located on the two metal frames 2 on the sides. The end of the connecting rod 503 is movably connected to the metal frame 2 through the connecting pin 504. The connecting pin 504 is made of high-hardness alloy steel and the surface is quenched to ensure the reliability and durability of the connection. When the cylinder 3 is running, its piston rod extends or retracts, driving the hollow head 502 to move in a straight line, which in turn causes the two connecting rods 503 to move accordingly. Due to the connection method between the connecting rods 503 and the metal frame 2, the ends of the two connecting rods 503 will pull the metal frame 2 on the side to rotate around the hinge, eventually making the adjacent sides of the two metal frames 2 close together to form a stable triangular structure. This triangular structure can effectively surround the photovoltaic panel 1 on the one hand, reducing the risk of collision with the photovoltaic panel 1 by external objects. On the other hand, according to the principle of aerodynamics, the triangular structure can guide the storm, change the direction of the storm, and prevent the photovoltaic panel 1 from being directly hit by the storm, thereby effectively preventing the photovoltaic panel 1 from being damaged by strong winds.
[0023] Stress-relief structure: To further enhance the safety of the photovoltaic module in storm conditions, both ends of the back side of the metal frame 2 are equipped with a surrounding structure 6, and a stress-relief structure 7 is set between the two surrounding structures 6. The surrounding structure 6 includes three side plates 601, which are made of aluminum alloy and are fixed to the metal frame 2 by riveting or bolting. A semi-circular ring 602 is installed on one side of the side plate 601. The semi-circular ring 602 is a 120-degree arc and is made of high-strength plastic, with good flexibility and impact resistance. The three semi-circular rings 602 form a complete ring structure, with the middle semi-circular ring 602 and the side semi-circular rings 602... The ends are hinged, allowing the entire ring structure to open and close flexibly. One end of the two side semi-circular rings 602 that interlock is designed with a reinforced concave-convex structure, consisting of a groove and a protrusion 9. Both the groove and protrusion 9 are made of high-strength plastic and are integrally molded with the semi-circular rings 602 through injection molding. When the three semi-circular rings 602 are combined into a complete ring, the groove and protrusion 9 can precisely engage, achieving reliable fixation. In the non-fixed state, the interlocking ends of the two side semi-circular rings 602 are secured with a threaded fixing sleeve 8. The fixing sleeve 8 is made of metal and is used to maintain the relative position of the semi-circular rings 602 when not in use, preventing them from shifting. The pressure relief structure 7, which allows for free swaying, includes a sliding arc plate 701. The sliding arc plate 701 is an arc-shaped plate made of lightweight alloy material, possessing good strength and wind resistance. The sliding arc plate 701 has a groove 702, the size and shape of which precisely matches the cross-section between the side plate 601 and the semi-circular ring 602, ensuring that the sliding arc plate 701 can slide along the trajectory of the semi-circular ring 602. The pressure relief structure 7 also includes two pressure relief vanes 703, made of lightweight plastic material. Their ends are fixed to one side of the sliding arc plate 701 by glue or riveting. When encountering severe weather such as typhoons and rainstorms, the pressure relief structure allows for free swaying. When cylinder 3 operates, it drives the three metal frames 2 to form a triangular shape. At the same time, the three semi-circular rings 602 rotate into a ring structure, and the beginning and end are fixed by engaging the protrusions 9 and the grooves. When a storm passes by, the force of the wind will blow the stress relief rotor 703. Due to the connection between the stress relief rotor 703 and the sliding arc plate 701, the sliding arc plate 701 will move further along the ring formed by the three semi-circular rings 602. In this process, part of the energy of the storm is consumed by the movement of the sliding arc plate 701, thereby achieving stress relief again, further reducing the impact of the storm on the photovoltaic panel 1 module, and improving its survivability under severe weather conditions.
