Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and more specifically, to a photovoltaic support. Background Technology
[0002] Photovoltaic (PV) mounting systems are key structural components used to support and fix PV modules in solar photovoltaic (PV) power generation systems. Primarily made of materials such as steel and aluminum alloys, they possess excellent wind, earthquake, and corrosion resistance. Their function is to fix the PV modules at the optimal angle to maximize sunlight reception and improve power generation efficiency. Depending on the installation method, they can be divided into fixed and tracking types. Fixed mounting systems are simple in structure and low in cost, suitable for areas with stable sunlight conditions; tracking mounting systems can adjust their angle according to the sun's position, resulting in higher power generation efficiency, but are also relatively more expensive. The design of PV mounting systems must consider local climate conditions, topography, and installation space to ensure the safe and stable operation of the system. With the rapid development of the photovoltaic industry, PV mounting systems are also evolving towards lightweight and intelligent designs to meet the needs of different application scenarios.
[0003] In fixed, modular photovoltaic (PV) support systems, the various components are secured using connectors. For the purlins and main beams, L-shaped connecting plates are primarily used in conjunction with bolts. Because the main beam is inclined, the PV panels exert a significant weight on the purlins in the downward direction of the main beam. Over prolonged periods, this can cause deformation of the L-shaped connecting plates, making it difficult to guarantee the stability of the PV panels. Therefore, we propose a new PV support system. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a photovoltaic support to solve the technical problem that the connecting parts of the purlins and main beams are prone to deformation during use, making it difficult to ensure the stability of the photovoltaic panels.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a photovoltaic support, including legs, a main beam, and a connecting plate installed on the main beam. The main beam is inclined and there are two main beams. The lower ends of the two main beams are symmetrically equipped with legs by bolts. Fixing members are installed on the legs by bolts and nuts. Reinforcing rods are installed on the legs by fixing members. The ends of the reinforcing rods are bolted to the outer surface of the main beam. A connecting plate is installed on the upper end of the main beam by bolts. Purlins are installed on the connecting plate and supported on the upper end of the main beam. The cross-section of the purlins is U-shaped.
[0006] Preferably, the fixing component includes symmetrically arranged fixing plates, the fixing plates are arranged in a semi-circular shape, the support legs are located between the fixing plates, and the two ends of the fixing plates are respectively provided with a first mounting part and a second mounting part, and the first mounting part and the second mounting part are connected by bolts and nuts.
[0007] Preferably, a fixing part is provided at the end of the second mounting part, which is bent outward. The fixing part is L-shaped and is connected to the reinforcing rod by bolts.
[0008] Preferably, the connecting plate includes a first connecting part and a second connecting part, the first connecting part and the second connecting part forming an L-shape, the first connecting part being installed on the main beam by bolts, and the purlin being fixedly connected to the second connecting part by bolts.
[0009] Preferably, the lower end of the second connecting part is provided with a support part, the support part is supported on the lower end of the purlin, and the end of the support part is bent upward to provide an L-shaped first limiting part. A first limiting opening is formed between the first limiting part and the support part, and the lower end of the first limiting part contacts the inner wall of the bottom end of the purlin.
[0010] Preferably, the end of the first limiting part is bent upward to form a second limiting part, and a second limiting opening is formed between the second limiting part and the second connecting part. The second connecting part is attached to the inner wall of the purlin, and a bolt between the second connecting part and the purlin passes through the second limiting part to install a nut. The end of the second limiting part is bent to form an L-shaped tension part, and the end of the tension part forms a hook that contacts the front end of the purlin.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the design of a connecting plate structure, establishes an L-shaped basic structure with the first and second connecting parts. Combined with bolts, this allows for the initial fixing of the main beam and purlin, laying the foundation for subsequent stable connection. The support part, first limiting part, second limiting part, and tension part at the lower end of the second connecting part work together to construct a multi-directional, multi-layered limiting system. The support part directly supports the lower end of the purlin. The first limiting part is embedded in the inner wall of the purlin's bottom end and achieves initial limiting through the first limiting opening, preventing the purlin from moving left or right. The second limiting part, in conjunction with the bolts, enhances the connection strength. The second limiting opening limits the rear end of the purlin, forming a stable three-dimensional limiting frame. In terms of mechanical performance, when the photovoltaic panel is installed and the connecting plate bears a downward tilting force, the tension part, as a key force transmission component, cleverly transmits the force to the purlin. Combined with the purlin part embedded... The structure embedded within the connecting plate significantly disperses the stress on the connecting plate, effectively preventing deformation and ensuring the installation strength of the connecting plate to the purlins. This makes the photovoltaic panel fixing more stable and reliable. Simultaneously, this structural design makes the connection between the connecting plate and the purlins and main beams tighter, effectively resisting the impact of external factors such as wind and vibration on the photovoltaic support system, thus improving the safety and stability of the entire photovoltaic support system. In terms of installation and maintenance, the modular design of the connecting plate makes the installation process simple and convenient. The bolted connection facilitates disassembly and replacement, reducing maintenance costs and difficulty, improving the practicality and economy of the photovoltaic support system, and enhancing the stability of the entire photovoltaic support system. This solves the problem that current purlin and main beam connectors are prone to deformation during use, making it difficult to ensure the stability of the photovoltaic panel fixing.
[0013] 2. This utility model also designs a fixing structure. The fixing component set on the support leg cooperates with the reinforcing rod. The fixing component is installed on the support leg through a semi-circular fixing plate and the first and second mounting parts with bolts and nuts. The fixing part at the end of the second mounting part is connected to the reinforcing rod. The other end of the reinforcing rod is fixed to the outer surface of the main beam, forming a stable triangular reinforcement structure. This structure can effectively disperse various external forces on the support during use, such as wind force and the weight of the photovoltaic panel itself, thereby enhancing the overall wind and earthquake resistance of the support and reducing the swaying or deformation of the support due to uneven force. This ensures that the photovoltaic support can still operate stably under complex environmental conditions. Attached Figure Description

Detailed Implementation
[0023] like Figures 1 to 8 As shown, this utility model relates to a photovoltaic support, including support legs 101, main beam 102, and connecting plate 301 installed on the main beam 102. The main beam 102 is inclined and has two main beams. Support legs 101 are symmetrically installed on the lower ends of the two main beams 102 by bolts. Fixing members 200 are installed on the support legs 101 by bolts and nuts. Reinforcing rods 103 are installed on the support legs 101 by fixing members 200. The end of the reinforcing rod 103 is connected to the outer surface of the main beam 102 by bolts. Connecting plate 301 is installed on the upper end of the main beam 102 by bolts. Purlins 104 are installed on the connecting plate 301 and are supported on the upper end of the main beam 102. The cross section of purlins 104 is U-shaped. The photovoltaic bracket of this utility model has an innovative structure of connecting plate 301 and fastener 200. The former constructs a multi-directional limiting system to disperse stress, while the latter forms a stable triangular reinforcement structure, which effectively enhances the stability and resistance to external forces of the bracket, thereby improving the stability and practicality of the bracket.
[0024] Specifically, the fastener 200 includes symmetrically arranged fixing plates 201 in a semi-circular shape. The support legs 101 are located between the fixing plates 201. A first mounting portion 202 and a second mounting portion 203 are respectively provided at both ends of the fixing plates 201. The first mounting portions 202 and the second mounting portions 203 are connected to each other by bolts and nuts. The annular fixing plates 201 can be fitted onto the support legs, and the first mounting portions 202 and the second mounting portions 203, in conjunction with bolts and nuts, can fix the fastener 200 onto the support legs 101.
[0025] Furthermore, a fixing part 204 is provided at the end of the second mounting part 203, which is bent outward. The fixing part 204 is L-shaped and is connected to the reinforcing rod 103 by bolts. The fixing plate 204 connects the reinforcing rod 103 to the fixing member 200, and the outward bending of the second mounting part 203 allows the end of the reinforcing rod 103 to be located outside the purlin 104, facilitating the connection between the reinforcing rod 103 and the purlin 104.
[0026] It is worth noting that the connecting plate 301 includes a first connecting part 302 and a second connecting part 303, which form an L-shape. The first connecting part 302 is bolted to the main beam 102, and the purlin 104 is fixedly connected to the second connecting part 303 by bolts. The arrangement of the first connecting part 302 and the second connecting part 303, together with the bolts, can initially fix the main beam 102 and the purlin 104.
[0027] It is worth noting that a support portion 304 is provided at the lower end of the second connecting portion 303. The support portion 304 supports the lower end of the purlin 104. The end of the support portion 304 is bent upward to form an L-shaped first limiting portion 305. A first limiting opening 306 is formed between the first limiting portion 305 and the support portion 304. The lower end of the first limiting portion 305 contacts the inner wall of the bottom end of the purlin 104. The support portion 304 can support the lower end of the purlin 104. The upwardly bent first limiting portion 305 can be located on the inner wall of the bottom end of the purlin 104. The lower part of the purlin 104 is limited by the first limiting opening 306 formed by the support portion 304 and the first limiting portion 305.
[0028] It is worth noting that the end of the first limiting part 305 is bent upward to form a second limiting part 307. The second limiting part 307 and the second connecting part 303 form a second limiting opening 308. The second connecting part 303 is attached to the inner wall of the purlin 104. The bolt between the second connecting part 303 and the purlin 104 passes through the second limiting part 307 and is fitted with a nut. The end of the second limiting part 307 is bent to form an L-shaped tension part 309. The end of the tension part 309 forms a hook that contacts the front end of the purlin 104. The second limiting part 307 can be connected to the bolt between the second connecting part 303 and the purlin 104, which can ensure the connection strength between the main beam 102 and the purlin 104. The rear end of the purlin 104 passes through the second limiting opening 308 formed between the second limiting part 307 and the second connecting part 303, which can limit the purlin 104 again. The L-shaped setting of the tension part 309 can contact the front end of the purlin 104. When the connecting plate 301 is subjected to a downward tilting force, the tension part 309 can link the force to the purlin 104. With the purlin 104 part located inside the connecting plate 301, it can effectively prevent the connecting plate 301 from deforming, ensure the installation strength of the connecting plate 301 to the purlin 104, and make the photovoltaic panel fixed with high stability.
[0029] Working Principle: This embodiment provides a photovoltaic support system. In use, firstly, the legs 101 are symmetrically installed to the lower end of the main beam 102 using bolts, constructing the basic frame of the photovoltaic support system. Next, a semi-circular fixing plate 201 is fitted onto the legs 101 and secured with bolts and nuts between the first mounting part 202 and the second mounting part 203, ensuring the fixing member 200 is firmly installed on the legs 101. Subsequently, the reinforcing rod 103 is connected to the fixing part 204 using bolts, and its end is then fixed to the outer surface of the main beam 102 with bolts, forming a stable reinforcing structure. This effectively enhances the overall stability of the support system and distributes the force borne by the support system. When installing the purlins 104, the first connecting part 302 of the connecting plate 301 is first installed on the upper end of the main beam 102 using bolts. Then, the purlins 104 are inserted into the connecting plate 301 through the first limiting opening 306 and the second limiting opening 308. The main beam 102 supports the purlins 104 simultaneously. The support part 304 also supports the lower end of the purlin 104. The first limiting part 305 is embedded in the inner wall of the bottom end of the purlin 104, and the purlin 104 is initially limited through the first limiting port 306 to prevent it from moving left or right. Then, a bolt is used to pass through the second limiting part 307 to fix the second connecting part 303 to the purlin 104. After the nut is tightened, the second limiting part 307 further enhances the connection strength. At the same time, the second limiting port 308 supports the rear end of the purlin 104. After limiting the position, the hook of the tension part 309 contacts the front end of the purlin 104. When the photovoltaic panel is installed, the connecting plate 301 is subjected to a downward tilting force, and the tension part 309 transmits the force to the purlin 104. Combined with the structure in which the purlin 104 is partially embedded in the connecting plate 301, the deformation of the connecting plate 301 is effectively prevented, ensuring that the purlin 104 is firmly connected to the main beam 102, thereby ensuring the stability of the photovoltaic panel and enabling the photovoltaic bracket to stably support the photovoltaic panel.
