Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a horizontal and vertical deformable photovoltaic support. Background Technology

[0002] As a crucial component of clean energy, the installation method and support structure of photovoltaic (PV) power generation systems directly impact power generation efficiency and system reliability. Traditional PV support systems typically employ a fixed installation structure, with PV panels fixed to the support in a single direction (horizontal or vertical). This fixed structure has numerous limitations in practical applications, severely restricting the power generation efficiency and adaptability of PV systems.

[0003] Traditional photovoltaic (PV) mounting systems cannot adjust the installation orientation of PV panels according to seasonal changes. Due to the Earth's orbit, the solar altitude angle changes with the seasons. In the Northern Hemisphere, the solar altitude angle is higher in summer and lower in winter. Fixed-direction installation cannot adapt to this seasonal variation, leading to a significant decrease in power generation efficiency in winter. Studies show that the difference in power generation varies across different latitudes. Generally, for high-latitude regions, seasonally adjusting the installation angle can increase power generation by about 6% compared to the optimal tilt angle; for low-latitude regions (near the equator), seasonally adjusting the installation angle can increase power generation by about 25% compared to the optimal tilt angle.

[0004] In high-latitude regions, where a smaller installation angle (0-45°) is required, vertical installation is possible with minimal downward shading. In low-latitude regions, where a larger installation angle (45-90°) is required, horizontal installation can increase the installation angle and reduce the area of ​​downward shading. This change in angle increases power generation.

[0005] At the same time, within the same region, the horizontal and vertical installation can be adjusted according to seasonal changes (no need for frequent changes, at most once a quarter is sufficient), achieving the following functions:

[0006] Summer shading mode: Install photovoltaic panels horizontally and adjust the tilt angle to a suitable angle to combine power generation and shading functions, reducing indoor air conditioning load.

[0007] Winter high-efficiency power generation mode: Switch to vertical installation, adjust the tilt angle, and maximize the reception of low-angle solar radiation.

[0008] Suitable for narrow spaces: In vertical mode, the photovoltaic modules are placed close to the side wall of the balcony to reduce space occupation.

[0009] Existing technologies lack the ability to quickly adjust the orientation of photovoltaic panels and cannot optimize system configuration in a timely manner according to weather changes.

[0010] From a structural design perspective, traditional support systems have complex connection methods and numerous components, which not only increases manufacturing costs but also reduces system reliability. Especially in scenarios requiring frequent adjustments, excessive connectors can easily lead to loosening, wear, and other problems, affecting the system's lifespan.

[0011] Therefore, we propose a horizontally and vertically deformable photovoltaic support. Utility Model Content

[0012] Therefore, it is necessary to address the technical problems of traditional photovoltaic support systems, such as fixed orientation in a single direction, inability to flexibly adjust the orientation of photovoltaic panels, resulting in limited power generation efficiency, serious material waste, and high installation and maintenance costs. A horizontal and vertical deformable photovoltaic support system should be provided, which allows photovoltaic panels to be quickly switched between horizontal and vertical arrangement according to seasonal changes or installation environment requirements, maximizing power generation efficiency, while reducing material costs and installation and maintenance difficulty, and improving the versatility and reliability of the system.

[0013] The first aspect of this utility model provides a horizontally and vertically deformable photovoltaic support bracket, including fixed frames and movable components. The fixed frames are two in number and symmetrically distributed. Each fixed frame includes a second connector, a third connector, and a fifth connector connected to each other. The third and fifth connectors are fixed to both ends of the second connector in the same direction. The movable components include two connectors of two different lengths. One type of connector connects the two fixed frames, and the other type is located at the movable ends of the third and fifth connectors. The fifth connector is a telescopic structure, and its length in its shortest state is still greater than that of the third connector. A positioning locking device is provided on the fifth connector. This design achieves rapid conversion of the photovoltaic panel orientation through modular assembly, eliminating the need to disassemble and rebuild the support system, significantly improving power generation efficiency. The symmetrical distribution and fixed structure of the fixed frames ensure mechanical balance, and the telescopic fifth connector, in conjunction with the locking device, enables precise adjustment of the photovoltaic panel tilt angle, adapting to the installation needs of different latitude regions.

[0014] In other embodiments, both the third and fifth connecting members have a rotating shaft at their movable ends, and corresponding through holes are provided on the movable parts. This rotating shaft design prevents damage to the movable parts during rotation, ensuring the long-term stable operation of the support system. The fit precision between the rotating shaft and the through holes has been rigorously calculated and tested, ensuring smooth rotation within a temperature range of -30℃ to +60℃. Furthermore, the low coefficient of friction allows for manual torque adjustment by a single person, reducing maintenance difficulty and costs.

[0015] In other embodiments, a movable component connected to the movable ends of the third and fifth connectors is used to fix the photovoltaic panel. This movable component not only serves a connecting function but also undertakes the important function of fixing the photovoltaic panel. Its design fully considers the stress characteristics of the photovoltaic panel when arranged in different directions, and through differentiated lengths and precise matching, it ensures edge alignment and uniform stress of the photovoltaic panel after installation.

[0016] In other embodiments, a mounting component is also connected to the movable component between the two fixed frames, and the mounting component is fixedly connected to the connecting surface. This mounting component design allows the photovoltaic support system to be moved and disassembled as a whole, improving the system's flexibility and maintainability. Simultaneously, the fixed connection between the mounting component and the connecting surface ensures the overall stability of the support system, preventing loosening or displacement due to vibration or wind loads.

[0017] In other embodiments, the connectors are all U-shaped structures, and the width of the end face used for connection varies among different connectors. The U-shaped structure is chosen based on its excellent mechanical properties and ease of processing. The difference in end face width among the different connectors creates a natural anti-misalignment structure, avoiding directional errors during installation. Simultaneously, the cross-sectional design of the U-shaped structure is optimized, achieving lightweighting while ensuring strength, thus reducing material costs and transportation difficulties.

[0018] In other embodiments, the second connector is arranged parallel to the connection surface. This parallel arrangement ensures vertical load transfer and avoids the impact of lateral forces on the building structure. Simultaneously, the angle of the photovoltaic panel is flexibly adjusted through the use of third and fifth connectors of different lengths, and the telescopic design of the fifth connector. This design allows the support system to adapt to different terrains and installation environments, improving the system's versatility and adaptability.

[0019] In other embodiments, the spacing between the two mounting brackets is adjusted according to the length of different moving parts. This design allows the support system to perfectly match photovoltaic panels of different sizes, avoiding material waste or installation difficulties caused by size mismatch. Simultaneously, by adjusting the spacing of the mounting brackets, the spacing and arrangement of the photovoltaic panels can be optimized, improving the overall power generation efficiency of the photovoltaic array.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, this embodiment discloses a horizontally and vertically deformable photovoltaic support 100, which includes a fixed frame and movable components, enabling separate horizontal and vertical fixation of the photovoltaic panel 200. Traditional photovoltaic supports typically only fix the photovoltaic panel 200 in a single direction. When the orientation of the photovoltaic panel 200 needs to be adjusted, the entire support system often needs to be disassembled and rebuilt. The core innovation of this design lies in the ingenious combination of the fixed frame and movable components, which enables rapid conversion between horizontal and vertical arrangement of the photovoltaic panel 200.

[0030] In this embodiment, the photovoltaic panel 200 is typically rectangular, meaning that the side lengths in the two directions are different. Therefore, this application adjusts the photovoltaic support 100 according to different seasons, which can adjust the direction of the photovoltaic panel 200 so that the photovoltaic panel 200 can be installed horizontally or vertically on the photovoltaic support 100, without the need for two separate supports.

[0031] like Figure 5 As shown, in this embodiment, there are two fixing frames symmetrically distributed. Each fixing frame includes a second connecting member 20, a third connecting member 30, and a fifth connecting member 50 that are connected to each other. The third connecting member 30 and the fifth connecting member 50 are fixed to both ends of the second connecting member 20 in the same direction. At the same time, there is a certain angle between the third connecting member 30 and the fifth connecting member 50 and the second connecting member 20. In this embodiment, the third connecting member 30 and the fifth connecting member 50 are parallel and perpendicular to the second connecting member 20, so that the fixing frame can remain unchanged whether the photovoltaic bracket 100 is in the horizontal or vertical direction, thereby improving the deformation efficiency.

[0032] The movable component in this embodiment includes two connectors of different lengths, and there are two of each connector, namely the first connector 10 and the fourth connector 40. In this embodiment, the length of the first connector 10 is greater than that of the fourth connector 40. One connector is used to connect two fixed frames, and the other connector is located at the movable end of the third connector 30 and the fifth connector 50.

[0033] like Figure 1 and Figure 3 As shown, when the photovoltaic panel 200 needs to be arranged horizontally, the spacing between the two fixing frames corresponds to the length direction of the photovoltaic panel 200. The spacing between the two fixing frames is fixed by the longer first connecting member 10, while the width direction is supported by the shorter fourth connecting member 40.

[0034] like Figure 2 and Figure 4 As shown, when the photovoltaic panel 200 needs to be arranged vertically, the first connector 10 and the fourth connector 40 are replaced to achieve the corresponding horizontal and vertical arrangement of the photovoltaic panel 200.

[0035] The movable ends of the third connector 30 and the fifth connector 50 are both provided with rotating shafts 70, and corresponding through holes are provided on the movable parts, so that the corresponding movable parts will not be damaged when they rotate.

[0036] The fifth connector 50 is a telescopic structure, and its length in its shortest state is still greater than that of the third connector 30. In this embodiment, when the photovoltaic bracket 100 is arranged vertically, the fifth connector 50 is placed at the lower end, so that the photovoltaic panel 200 tilts upward. As the fifth connector 50 extends and retracts, the incident angle of the photovoltaic panel 200 is adjusted. A positioning locking member 60 is provided on the fifth connector 50 to achieve telescopic fixation.

[0037] The movable parts connected to the movable ends of the third connector 30 and the fifth connector 50 are used to fix the photovoltaic panel 200, and the fixing methods include bolt connection or clamping fixation.

[0038] A mounting component 400 is also connected to the movable component between the two fixed frames, and the mounting component 400 is fixedly connected to the connecting surface 300.

[0039] All connectors are U-shaped structures, and the width of the end face used for connection differs among the connectors. For example, when the third connector 30 and the fifth connector 50 contact the second connector 20, the width of the corresponding end face of the third connector 30 and the fifth connector 50 is smaller than the width of the opening of the second connector 20, thus facilitating corresponding snap-fit ​​connection. Figure 5 As shown, the snap-fit ​​connection in this embodiment can be achieved by connecting two positioning pins.

[0040] The second connector 20 is arranged parallel to the connecting surface 300, thereby adjusting the angle of the photovoltaic panel 200 through the third connector 30 and the fifth connector 50 of different lengths, and the telescopic setting of the fifth connector 50.

[0041] The spacing between the two fixing frames is adjusted according to the length of different movable parts, so that the two fixing frames can correspond to the changes in the length and width of the photovoltaic panel 200. The above description is an explanation of this utility model and not a limitation thereof. The scope of this utility model is defined by the claims, and any modifications can be made within the protection scope of this utility model.
