Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, specifically to an aluminum frame for photovoltaic modules that facilitates rapid assembly. Background Technology

[0002] As a core component of solar power generation systems, photovoltaic (PV) modules are exposed to complex outdoor environments for extended periods, enduring harsh conditions such as wind, sun, rain, snow, and temperature fluctuations. The aluminum frame, acting as the "skeleton" of the PV module, plays a crucial role in protecting the edges of the photovoltaic glass, enhancing the overall mechanical strength of the module, improving sealing, and facilitating installation and transportation. Its performance directly determines the lifespan, mechanical reliability, and power generation efficiency stability of the PV module.

[0003] Existing aluminum frames are typically composed of four aluminum profiles joined together. Assembly requires precisely inserting corner brackets into the cavities of the aluminum profiles, followed by tightening screws with specialized tools. This process is time-consuming and labor-intensive, making it unsuitable for the high-efficiency demands of large-scale production. Furthermore, the screws, exposed to outdoor conditions, are susceptible to corrosion from rain and moisture, leading to loose connections and compromising the overall structural strength of the aluminum frame. Most current mainstream photovoltaic (PV) mounting systems employ a fixed tilt angle design, setting the angle once based solely on experience with the installation area. This fails to adapt to dynamic changes in the solar altitude angle throughout the day and night. Consequently, the amount of solar radiation received by the PV modules remains suboptimal, with particularly noticeable efficiency losses during winter or early morning / evening periods when the solar altitude angle is low. While some existing technologies attempt to adjust the angle manually or mechanically, manual adjustment suffers from poor timeliness and reliance on human experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an aluminum frame for photovoltaic modules that facilitates rapid assembly, solving the problems of poor assembly convenience and the inability to automatically adjust the angle of existing photovoltaic modules.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum frame for photovoltaic modules that is easy to assemble quickly, comprising a base plate, a vertical frame, and a horizontal frame. The base plate is provided with an adjustment component for adjusting the angle of the photovoltaic module, and the vertical frame is provided with a quick-release component for quickly disassembling the photovoltaic module.

[0006] The adjustment assembly includes a fixed frame fixedly connected to the upper surface of the base plate. The fixed frame has an installation groove, in which a ball bearing is installed. A sleeve shaft is fixedly connected to the inner ring wall of the ball bearing. A rotating frame is fixedly connected to the end of the sleeve shaft away from the base plate. A rotating shaft is sleeved inside the sleeve shaft and is rotatably connected to the rotating frame. A shaft is rotatably connected inside the rotating frame, and a swing seat is fixedly connected to the outer wall of the shaft.

[0007] The quick-release assembly includes two symmetrically arranged insertion holes on the horizontal frame. A threaded seat is fixedly connected to each insertion hole. A frame is fixedly connected to the vertical frame. A drive shaft is rotatably connected to the frame. Threaded rods are fixedly connected to both ends of the drive shaft, and the threaded rods are threadedly connected to the threaded seat.

[0008] Preferably, a connecting rod is fixedly connected to the outer wall of the swing seat, and a support plate is fixedly connected to the end of the connecting rod away from the swing seat.

[0009] Preferably, an adjustment plate is fixedly connected to one end of the support plate near the vertical frame, and two sliding grooves are symmetrically formed on the other end of the adjustment plate away from the support plate.

[0010] Preferably, the adjustment plate has a mounting hole, and a rotating motor is fixedly connected in the mounting hole.

[0011] Preferably, the output end of the rotary motor is fixedly connected to a rotating plate, a slide block is slidably connected in the slide groove, and hinge plates are rotatably connected to both ends of the rotating plate, with the hinge plates rotatably connected to the slide block.

[0012] Preferably, a clamping plate is fixedly connected to the upper surface of the slide block, and the clamping plate abuts against the horizontal frame.

[0013] Preferably, photosensitive sensors are installed near the four corners of the support plate, and slots are provided at the ends of the vertical and horizontal frames away from the clamping plate.

[0014] Preferably, a gear ring is fixedly connected to the end of the sleeve shaft away from the rotating frame, a worm wheel is fixedly connected to the outer wall of the drive shaft, a drive motor is fixedly connected inside the frame, and a worm is fixedly connected to the output end of the drive motor, with the teeth of the worm meshing with the teeth of the worm wheel.

[0015] Preferably, a second bevel gear is fixedly connected to one end of the rotating shaft located inside the rotating frame, and a spur gear is fixedly connected to the other end of the rotating shaft.

[0016] Preferably, a first bevel gear is fixedly connected to the outer wall of the shaft, and the teeth of the first bevel gear mesh with the teeth of the second bevel gear.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention involves inserting the vertical frame into the horizontal frame along the insertion hole. The drive shaft inside the vertical frame rotates, driving the threaded rods at both ends to connect with the threaded seats inside the horizontal frame, thus achieving rapid installation of the horizontal and vertical frames. After installation, the threaded seats are located in the sealed space formed by the vertical and horizontal frames, preventing the threaded seats and threaded rods from being corroded by rainwater and moisture, which helps to improve the overall structural strength of the photovoltaic module. The threaded rods use left-hand and right-hand threads with the same pitch at both ends, which can quickly complete the rapid assembly of the horizontal and vertical frames.

[0019] 2. This invention uses identical photosensitive sensors installed at the four corners of a support plate. When sunlight shines directly on the photovoltaic module, the light intensity received by each sensor is equal. If the sunlight shifts and the light intensity of a sensor in a certain direction is higher, the controller automatically drives the motor to adjust the angle of the support plate, so that the photovoltaic module is always in the state of highest power generation efficiency, realizing intelligent adjustment of the device and improving the intelligence level of the device.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] refer to Figures 1-7 The image shows an aluminum frame for a photovoltaic module that facilitates rapid assembly. It includes a base plate 1, a vertical frame 3, and a horizontal frame 4. The base plate 1 has an adjustment component for adjusting the angle of the photovoltaic module. The vertical frame 3 has a quick-release component for rapid disassembly of the photovoltaic module. A specific embodiment is shown below:

[0030] Example 1

[0031] The quick-release assembly includes two symmetrically arranged insertion holes 22 on the horizontal frame 4. A threaded seat 24 is fixedly connected inside the insertion hole 22. A frame 27 is fixedly connected inside the vertical frame 3. A drive shaft 26 is rotatably connected inside the frame 27. Threaded rods 25 are fixedly connected to both ends of the drive shaft 26, and the threaded rods 25 are threadedly connected to the threaded seat 24. A worm gear 28 is fixedly connected to the outer wall of the drive shaft 26. A drive motor 29 is fixedly connected inside the frame 27. A worm 30 is fixedly connected to the output end of the drive motor 29, and the teeth of the worm 30 mesh with the teeth of the worm gear 28.

[0032] Insert the vertical frame 3 along the insertion hole 22 on the horizontal frame 4. Two threaded rods 25 are fixedly connected to both ends of the drive shaft 26. The two threaded rods 25 are left- or right-hand threads with the same pitch. Driven by the drive motor 29, the worm gear 30 rotates, causing the worm wheel 28 and the drive shaft 26 to rotate synchronously. The two threaded rods 25 rotate synchronously and are threadedly connected to the threaded seat 24 in the horizontal frame 4, so that the vertical frame 3 and the horizontal frame 4 can be quickly assembled.

[0033] Example 2

[0034] A connecting rod 11 is fixedly connected to the outer wall of the swing seat 14. A support plate 2 is fixedly connected to the end of the connecting rod 11 away from the swing seat 14. An adjusting plate 6 is fixedly connected to the end of the support plate 2 near the vertical frame 3. Two sliding grooves 21 are symmetrically opened at the end of the adjusting plate 6 away from the support plate 2. An installation hole 35 is opened on the adjusting plate 6. A rotating motor 20 is fixedly connected in the installation hole 35. A rotating plate 17 is fixedly connected to the output end of the rotating motor 20. A slide seat 18 is slidably connected in the sliding groove 21. A hinge plate 19 is rotatably connected to both ends of the rotating plate 17, and the hinge plate 19 is rotatably connected to the slide seat 18. A clamping plate 8 is fixedly connected to the upper surface of the slide seat 18, and the clamping plate 8 abuts against the horizontal frame 4.

[0035] The assembled photovoltaic module is placed on the support plate 2. The rotating motor 20 drives the rotating plate 17, which simultaneously pulls the hinge plates 19 at both ends. This, in turn, pulls the slide blocks 18 along the slide groove 21, bringing the two slide blocks 18 closer together. The clamping plate 8, fixedly connected to the slide blocks 18, moves synchronously, clamping the photovoltaic module and completing the rapid clamping and fixing of the photovoltaic module. When it is necessary to remove the photovoltaic module, the rotating motor 20 is rotated in the opposite direction. The rotating plate 17 simultaneously pushes the hinge plates 19, causing the slide blocks 18 to slide in the opposite direction along the slide groove 21, moving the two slide blocks 18 away from each other and releasing the clamping relationship between the clamping plate 8 and the photovoltaic module.

[0036] Example 3

[0037] A photosensitive sensor 5 is installed near the four corners of the support plate 2. A slot 23 is provided at the end of the vertical frame 3 and horizontal frame 4 away from the clamping plate 8. The adjustment assembly includes a fixing frame 7 fixedly connected to the upper surface of the base plate 1. A mounting groove 15 is provided on the fixing frame 7. A ball bearing 16 is installed in the mounting groove 15. A sleeve shaft 9 is fixedly connected to the inner ring wall of the ball bearing 16. A rotating frame 10 is fixedly connected to the end of the sleeve shaft 9 away from the base plate 1. A rotating shaft 12 is fitted inside the sleeve shaft 9, and the rotating shaft 12 is connected to the rotating frame 10. The rotating frame 10 is rotatably connected, and a shaft 13 is rotatably connected inside the rotating frame 10. A swing seat 14 is fixedly connected to the outer wall of the shaft 13. A gear ring 33 is fixedly connected to the end of the sleeve shaft 9 away from the rotating frame 10. A second bevel gear 32 is fixedly connected to one end of the rotating shaft 12 located inside the rotating frame 10. A spur gear 34 is fixedly connected to the other end of the rotating shaft 12. A first bevel gear 31 is fixedly connected to the outer wall of the shaft 13. The teeth of the first bevel gear 31 mesh with the teeth of the second bevel gear 32.

[0038] The support plate 2 is equipped with identical photosensitive sensors 5 near the four corners. When sunlight shines directly, the light intensity received by each sensor is equal. If the sunlight is deflected and the light intensity received by a sensor in a certain direction is higher, the controller supporting the device automatically drives the power motor to adjust the angle of the support plate 2. By adjusting the angle of the support plate 2, the angle of the photovoltaic module is adjusted accordingly. The power motor supporting the toothed ring 33 drives the toothed ring 33 to rotate, thereby driving the sleeve shaft 9 to rotate. The rotation of the sleeve shaft 9 drives the rotating frame 10 to rotate synchronously, adjusting the photovoltaic module on the support plate 2 in the horizontal direction. The power motor supporting the spur gear 34 drives the spur gear 34 to rotate, thereby driving the rotating shaft 12 to rotate. The rotating shaft 12 drives the second bevel gear 32 and the first bevel gear 31 to rotate, causing the connecting rod 11 to swing, thereby achieving the adjustment of the support plate 2 in the vertical direction. By adjusting the photovoltaic module on the support plate 2 in the horizontal and vertical directions as described above, multi-angle adjustment of the photovoltaic module is achieved, ensuring that the photovoltaic module is always directly irradiated by sunlight, and keeping the photovoltaic module on the support plate 2 in the state of the highest power generation efficiency at all times.

[0039] The working principle of the present invention is as follows: Insert the vertical frame 3 into the insertion holes 22 opened on the horizontal frame 4. Both ends of the drive shaft 26 are fixedly connected with two threaded rods 25. The drive motor 29 drives the worm 30 to rotate, causing the two threaded rods 25 to rotate synchronously and threadedly connected with the thread seats 24 in the horizontal frame 4. The assembled photovoltaic module as described above is placed on the support plate 2. The rotation motor 20 rotates to drive the rotating plate 17 to rotate, thereby pulling the sliding seat 18 to slide along the sliding groove 21. The clamping plate 8 fixedly connected with the sliding seat 18 moves synchronously, clamping the photovoltaic module with the clamping plate 8. When it is necessary to remove the photovoltaic module, reverse the rotation of the rotation motor 20. The rotating plate 17 simultaneously pushes the articulated plate 19, causing the sliding seat 18 to slide in the reverse direction along the sliding groove 21, making the two sliding seats 18 move away from each other, and releasing the clamping relationship between the clamping plate 8 and the photovoltaic module. If the sunlight is deflected and the light intensity received by a sensor in a certain direction is higher, the controller supporting the device automatically drives the power motor to adjust the angle of the support plate 2. The power motor supporting the toothed ring 33 drives the toothed ring 33 to rotate, thereby driving the sleeve shaft 9 to rotate. The rotation of the sleeve shaft 9 drives the rotating frame 10 to rotate synchronously, adjusting the photovoltaic module on the support plate 2 in the horizontal direction. The power motor supporting the spur gear 34 drives the spur gear 34 to rotate, thereby driving the rotating shaft 12 to rotate. The rotating shaft 12 drives the second bevel gear 32 and the first bevel gear 31 to rotate, causing the connecting rod 11 to swing, thereby achieving the adjustment of the support plate 2 in the vertical direction. By adjusting the photovoltaic module on the support plate 2 in the horizontal and vertical directions as described above, multi-angle adjustment of the photovoltaic module is achieved, ensuring that the photovoltaic module is always directly irradiated by sunlight, and keeping the photovoltaic module on the support plate 2 in the state of the highest power generation efficiency at all times.
