Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a windproof and reinforced photovoltaic array frame connection device. Background Technology

[0002] In the current era of rapid development of new energy, photovoltaic arrays, as the core equipment for solar power generation, are widely used in various scenarios, playing an important role in both large-scale ground-mounted photovoltaic power plants and rooftop distributed photovoltaic systems.

[0003] However, in actual use, it was found that the two long and two short frames fixed by the four diagonal brackets could not be accurately measured, which led to the problem of unreliable splicing of the long and short frames. At the same time, after a certain period of use, the splicing gaps of the long and short frames often widened and the height of the long and short frames were misaligned, which meant that the overall design had certain limitations.

[0004] A search revealed that Chinese patent CN216599520U discloses a connection structure for photovoltaic module frames. This structure features a multi-layered detachable design, combining stability and convenience. The locking blocks are connected to the support bars and receiving plates, while the support brackets are connected to the side plates and support bars via plug-in bolts. This ensures stability while enabling quick assembly and disassembly, improving assembly and maintenance efficiency. Furthermore, the support frame is secured between the side plates and receiving plates via support bars, and between the support plates via insert plates. Combined with the sliding engagement of the sliding grooves and support blocks, this enhances structural stability while simplifying the assembly and disassembly process. Additionally, the insertion of the receiving mesh limiting groove and the support frame inserts optimizes the stability of the photovoltaic module placement. The notches in the support bars facilitate positioning, and the use of sealing materials improves sealing. The overall design is practical and efficient.

[0005] However, in actual use, although the structure achieves stability and ease of assembly and disassembly through plug-in and bolt connections, the fixed support length and angle make it difficult to flexibly adjust according to different installation heights, terrain differences, or wind direction changes. As a result, in complex environments, the force direction of the support structure cannot be accurately matched with the tilt angle and wind direction of the photovoltaic array, thus limiting its wind resistance stability. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a windproof and reinforced photovoltaic array frame connection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A windproof and reinforced photovoltaic array frame connection device includes a frame connector. Multiple reinforcing steel bars are fixedly provided on one side of the frame connector. Mounting ears are fixedly provided on both sides of the frame connector. A photovoltaic frame is locked inside the mounting ears by bolts. An adjustment mechanism is provided on one side of the frame connector.

[0009] The adjustment mechanism includes a Z-shaped inner frame fixedly disposed on one side of the frame connector, a Z-shaped outer frame sleeved on the outer periphery of the Z-shaped inner frame, a fixed frame fixedly disposed on one side of the Z-shaped outer frame, a connecting rod rotatably connected inside the fixed frame, an adjustment sleeve sleeved on the outer periphery of the connecting rod, a protrusion fixedly disposed at one end of the adjustment sleeve, and a stabilizing frame rotatably connected to the surface of the protrusion.

[0010] The cross-section of the frame connector is Z-shaped, the fixed frame and the connecting rod are locked together by bolts, and the protrusion and the stabilizing frame are locked together by bolts.

[0011] The surface of the connecting rod is provided with an external threaded groove, and the surface of the adjusting sleeve is provided with multiple threaded holes. The threaded holes and the external threaded groove are internally threaded with anti-loosening locking bolts.

[0012] By adopting the above technical solution, the structure's torsional resistance and load-bearing capacity are enhanced through Z-shaped frame connectors and reinforcing steel bars, achieving flexible adaptation of support length and angle. This allows for precise response to different installation scenarios and wind direction requirements, significantly improving the wind resistance stability and installation adaptability of the photovoltaic array.

[0013] As a further description of the above technical solution: the inner sidewall of the Z-shaped outer frame is provided with an auxiliary mechanism, the auxiliary mechanism including a plurality of springs fixedly mounted on the inner sidewall of the Z-shaped outer frame, one end of the spring being fixedly connected to the surface of the frame connector, and a damper being fixedly mounted on one side of the spring, the two ends of the damper being fixedly connected to the inner sidewall of the Z-shaped outer frame and the surface of the frame connector, respectively.

[0014] By adopting the above technical solution, the energy of wind impact is absorbed through elastic deformation, which alleviates the instantaneous impact of the load on the structure. Moreover, the damper on one side of the spring is connected to the Z-shaped outer frame and the frame connector at both ends, which can effectively consume vibration energy and avoid structural fatigue caused by spring resonance.

[0015] As a further description of the above technical solution: a base plate is fixedly provided at the bottom of the stabilizing frame, and the outer surface of the frame connector is coated with an anti-rust coating, which is made of epoxy mica iron oxide primer material.

[0016] By adopting the above technical solution, the horizontal height of the device can be flexibly adjusted to adapt to different terrains. Moreover, the epoxy mica iron oxide primer anti-rust coating on the outer surface of the frame connector can effectively isolate moisture and corrosive media. Combined with reinforced steel bars, the structural durability is improved, the service life of the device in complex outdoor environments is greatly extended, and the long-term stable operation of the photovoltaic array is guaranteed.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up an adjustment mechanism, compared with the existing technology, a Z-shaped inner frame and outer frame sleeve structure is adopted, which provides a margin of movement for the frame connectors and support structure, forming a wind buffer space. Moreover, the threaded fit design of the connecting rod and the adjustment sleeve allows the sliding adjustment sleeve to be fixed by anti-loosening bolts, flexibly adjusting the support length to adapt to different installation heights and enhancing versatility. Secondly, the bolt locking and rotating structure of the fixed frame and the connecting rod, and the protrusion and the stabilizing frame, realizes multi-dimensional adjustment of the support angle, accurately matches the wind direction and the tilt angle of the photovoltaic array, and optimizes the force direction. This adjustable design allows the device to be easily debugged in complex terrain and climate conditions, ensuring that the support structure is in the optimal stress state, significantly improving wind resistance stability and installation convenience.

[0019] 2. By setting up auxiliary mechanisms, compared with existing technologies, when strong wind loads are transmitted from the photovoltaic frame to the frame connector, the springs on the inner wall of the Z-shaped outer frame quickly undergo elastic deformation, which can directly absorb a large amount of wind impact energy and initially alleviate the impact force of the load on the structure. At the same time, the damper on one side of the spring acts on the Z-shaped outer frame and the frame connector at both ends, effectively consuming the energy generated by the spring vibration and avoiding structural fatigue damage caused by resonance. This synergistic effect of the spring and the damper can significantly disperse the stress borne by the frame connector. Combined with its Z-shaped structure and internal reinforcing steel bars, it further prevents local deformation, ensures the stability of the connection, and greatly improves the wind resistance and structural safety of the photovoltaic array in strong wind environments.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The windproof and reinforced photovoltaic array frame connection device shown includes a frame connector 1. Multiple reinforcing steel bars 2 are fixedly installed on one side of the frame connector 1. Mounting ears 3 are fixedly installed on both sides of the frame connector 1. The photovoltaic frame 4 is locked inside the mounting ears 3 by bolts. An adjustment mechanism is provided on one side of the frame connector 1.

[0028] The adjustment mechanism includes a Z-shaped inner frame 5 fixedly installed on one side of the frame connector 1, a Z-shaped outer frame 6 fitted on the outer periphery of the Z-shaped inner frame 5, a fixed frame 7 fixedly installed on one side of the Z-shaped outer frame 6, a connecting rod 8 rotatably connected inside the fixed frame 7, an adjustment sleeve 9 fitted on the outer periphery of the connecting rod 8, a protrusion 10 fixedly installed at one end of the adjustment sleeve 9, and a stabilizing frame 11 rotatably connected to the surface of the protrusion 10.

[0029] The cross-section of the frame connector 1 is Z-shaped. The fixed frame 7 and the connecting rod 8 are locked together by bolts. The protruding block 10 and the stabilizing frame 11 are locked together by bolts.

[0030] The surface of the connecting rod 8 is provided with an external thread groove, and the surface of the adjusting sleeve 9 is provided with multiple threaded holes 12. The threaded holes 12 and the internal threads of the external thread groove are connected by anti-loosening locking bolts 13.

[0031] First, multiple reinforcing steel bars 2 on one side of the frame connector 1 are fixed by welding to ensure that the weld is covered with anti-rust coating 17 to enhance the structural strength of the frame connector 1. Then, an anti-rust coating 17 made of epoxy mica iron oxide primer is uniformly applied to the outer surface of the frame connector 1 to form a basic protective layer.

[0032] Then, using the mounting ears 3 on both sides of the frame connector 1, it is locked to the photovoltaic frame 4 with bolts, so that the adjacent photovoltaic modules can be stably connected through the frame connector 1, and the initial assembly and fixing of the photovoltaic array is completed.

[0033] Next, the outer circumference of the Z-shaped inner frame 5 fixed on one side of the frame connector 1 is fitted with the Z-shaped outer frame 6, so that the Z-shaped outer frame 6 can move within a certain range along the Z-shaped inner frame 5. Then, the fixing frame 7 is fixed on one side of the Z-shaped outer frame 6, and the connecting rod 8 is rotatably connected to the inside of the fixing frame 7 through the pivot, thus building the basic frame of the adjustment mechanism.

[0034] Furthermore, based on the installation height and support requirements of the photovoltaic array, the adjusting sleeve 9, which is slidably fitted on the outer circumference of the connecting rod 8, is aligned with the threaded hole 12 on the surface of the adjusting sleeve 9 through the external threaded groove on the surface of the connecting rod 8. The two are then threadedly connected and fixed with the anti-loosening locking bolt 13 to achieve the adjustment of the support length.

[0035] Reference Figure 2-3 As shown, the inner wall of the Z-shaped outer frame 6 is provided with an auxiliary mechanism, which includes multiple springs 14 fixedly installed on the inner wall of the Z-shaped outer frame 6. One end of the spring 14 is fixedly connected to the surface of the frame connector 1, and a damper 15 is fixedly installed on one side of the spring 14. The two ends of the damper 15 are fixedly connected to the inner wall of the Z-shaped outer frame 6 and the surface of the frame connector 1, respectively.

[0036] When encountering wind, when a strong wind load acts on the photovoltaic array, the load is first transferred to the photovoltaic frame 4 through the photovoltaic module. The photovoltaic frame 4 then transfers the force to the frame connector 1. At this time, the Z-shaped structure of the frame connector 1 plays an anti-torsion role, and the internal reinforcing steel bar 2 avoids local deformation by dispersing stress. The locking fit between the mounting ear 3 and the bolt ensures the efficient transfer of force between the photovoltaic frame 4 and the frame connector 1, preventing the connection from loosening and detaching.

[0037] Furthermore, the multiple springs 14 on the inner wall of the Z-shaped outer frame 6 undergo elastic deformation under the action of external force, absorbing some of the wind impact energy. At the same time, the two ends of the damper 15 on one side of the spring 14 act on the inner wall of the Z-shaped outer frame 6 and the surface of the frame connector 1, respectively, consuming the vibration energy of the spring 14 and reducing the vibration of the overall structure.

[0038] Reference Figure 4-5 As shown, a base plate 16 is fixedly installed at the bottom of the stabilizing frame 11, and the outer surface of the frame connector 1 is coated with an anti-rust coating 17, which is made of epoxy mica iron oxide primer material.

[0039] The stabilizing frame 11, which is rotatably connected to the surface of the protruding block 10 at one end of the adjusting sleeve 9, is locked in conjunction with the bolts between the fixed frame 7 and the connecting rod 8, and the bolts between the protruding block 10 and the stabilizing frame 11. The connection angle between the connecting rod 8 and the stabilizing frame 11 is adjusted to ensure that the support direction is adapted to the force requirements. Then, the base plate 16 supports the ground, which plays an auxiliary support role.

[0040] Working principle of this utility model:

[0041] This utility model is a windproof and reinforced photovoltaic array frame connection device. When using the device, firstly, multiple reinforcing steel bars 2 on one side of the frame connector 1 are fixed by welding to ensure that the weld is covered with anti-rust coating 17 to enhance the structural strength of the frame connector 1. Then, the outer surface of the frame connector 1 is uniformly coated with anti-rust coating 17 made of epoxy mica iron oxide primer material to form a basic protective layer.

[0042] Then, using the mounting ears 3 on both sides of the frame connector 1, it is locked to the photovoltaic frame 4 with bolts, so that the adjacent photovoltaic modules can be stably connected through the frame connector 1, and the initial assembly and fixing of the photovoltaic array is completed.

[0043] Next, the outer circumference of the Z-shaped inner frame 5 fixed on one side of the frame connector 1 is fitted with the Z-shaped outer frame 6, so that the Z-shaped outer frame 6 can move within a certain range along the Z-shaped inner frame 5. Then, the fixing frame 7 is fixed on one side of the Z-shaped outer frame 6, and the connecting rod 8 is rotatably connected to the inside of the fixing frame 7 through the pivot, thus building the basic frame of the adjustment mechanism.

[0044] Furthermore, based on the installation height and support requirements of the photovoltaic array, the adjusting sleeve 9, which is slidably fitted on the outer circumference of the connecting rod 8, is aligned with the threaded hole 12 on the surface of the adjusting sleeve 9 through the external threaded groove on the surface of the connecting rod 8, and then the two are threadedly connected and fixed with the anti-loosening locking bolt 13 to achieve the adjustment of the support length.

[0045] Next, rotate the stabilizing frame 11 connected to the surface of the protruding block 10 at one end of the adjusting sleeve 9, and lock it in place with the bolts between the fixed frame 7 and the connecting rod 8, as well as the bolts between the protruding block 10 and the stabilizing frame 11. Adjust the connection angle between the connecting rod 8 and the stabilizing frame 11 to ensure that the support direction is adapted to the force requirements, and then support the ground through the base plate 16.

[0046] When encountering wind, when a strong wind load acts on the photovoltaic array, the load is first transferred to the photovoltaic frame 4 through the photovoltaic module. The photovoltaic frame 4 then transfers the force to the frame connector 1. At this time, the Z-shaped structure of the frame connector 1 plays an anti-torsion role, and the internal reinforcing steel bar 2 avoids local deformation by dispersing stress. The locking fit between the mounting ear 3 and the bolt ensures the efficient transfer of force between the photovoltaic frame 4 and the frame connector 1, preventing the connection from loosening and detaching.

[0047] Furthermore, multiple springs 14 on the inner wall of the Z-shaped outer frame 6 undergo elastic deformation under external force, absorbing some of the wind impact energy. At the same time, the two ends of the damper 15 on one side of the spring 14 act on the inner wall of the Z-shaped outer frame 6 and the surface of the frame connector 1, respectively, consuming the vibration energy of the spring 14 and reducing the vibration of the overall structure. The damper 15 is a BE-60 damping rubber shock absorber.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
