Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an adaptive wind-resistant photovoltaic support. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed.

[0003] As the core component supporting photovoltaic panels, the performance of photovoltaic mounting systems directly affects the power generation efficiency and lifespan of the photovoltaic system. Currently, most photovoltaic mounting systems on the market are fixed structures that can only be fixed at a specific angle and cannot be adjusted according to changes in the sun's position. This results in photovoltaic panels not receiving sufficient sunlight at different times, limiting their photoelectric conversion efficiency.

[0004] When using the above-mentioned technologies, the following technical problems were found in the existing technologies: On the one hand, most of the photovoltaic brackets on the market are fixed structures that can only be fixed at a specific angle and cannot be adjusted according to changes in the sun's position, resulting in the photovoltaic panels not being able to receive sufficient sunlight at different times, thus limiting the photoelectric conversion efficiency; on the other hand, the surface of outdoor photovoltaic panels is prone to accumulating dust, fallen leaves and other debris. These pollutants will block light and significantly reduce the light transmittance of the photovoltaic panels, further affecting the power generation effect. Traditional cleaning methods mostly rely on manual cleaning, which is not only labor-intensive and costly, but also difficult to achieve timely cleaning in remote photovoltaic power stations and other scenarios. To address these issues, we designed an adaptive wind-resistant photovoltaic bracket to provide an alternative technical solution. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive wind-resistant photovoltaic support system to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An adaptive wind-resistant photovoltaic support includes a base frame, a rotating seat mounted on the top of the base frame, an adjusting plate rotatably connected to one end of the top of the rotating seat, a photovoltaic panel slidably connected to the top of the adjusting plate, a fixing block fixed to one end of the top of the adjusting plate, a clamping plate slidably connected to the other end of the top of the adjusting plate, and a pressure bolt threaded to the other end of the adjusting plate. One end of the pressure bolt is rotatably connected to the clamping plate, and the fixing block and the clamping plate are assembled and connected to the photovoltaic panel.

[0007] The inner sides of the fixing block and the clamping plate are fitted with protective pads.

[0008] Guide rods are fixed to both sides of one end of the clamping plate, and the outer side of the guide rods is slidably connected to the base frame.

[0009] One end of the regulating plate is equipped with a wind speed sensor.

[0010] The adjustment plate is provided with a reciprocating cleaning mechanism on its outer side for cleaning the surface of the photovoltaic panel. The reciprocating cleaning mechanism includes an adjustment screw, a U-shaped cleaning plate, a driven bevel gear, a main bevel gear, a transmission rod, and a two-phase servo motor. Adjustment screws are rotatably connected to both sides of the outer side of the adjustment plate, and U-shaped cleaning plates are slidably connected to both sides of the outer side of the adjustment plate. The outer side of the adjustment screw is threadedly connected to the U-shaped cleaning plate, and the U-shaped cleaning plate is slidably connected to the photovoltaic panel.

[0011] The adjustment plate has a protective box fixed to one end, a transmission rod rotatably connected to the inside of the protective box, main bevel gears fixed to both sides of the transmission rod, a driven bevel gear fixed to one end of the transmission rod, the driven bevel gear meshing with the main bevel gear, and a dual-phase servo motor mounted inside the protective box in the middle, the output end of the dual-phase servo motor being fixedly connected to the transmission rod.

[0012] The base frame and the adjustment plate are provided with a tracking mechanism for adjusting the orientation of the photovoltaic panel to track sunlight. The tracking mechanism includes a horizontal component and a vertical tilting component. The horizontal component is provided between the base frame and the rotating seat, and the vertical tilting component is provided between the rotating seat and the adjustment plate.

[0013] The horizontal component includes a second stepper motor, a transmission gear, and an arc-shaped rack. An arc-shaped guide groove is provided at one end of the top of the base frame. The inner side of the arc-shaped guide groove is slidably connected to the arc-shaped rack. The top end of the arc-shaped rack is rotatably connected to one end of the bottom of the rotating seat. The other end of the bottom of the rotating seat is rotatably connected to the base frame. A second stepper motor is mounted at one end of the base frame. The output end of the second stepper motor passes through the base frame and is fixed with a transmission gear. The outer side of the transmission gear is meshed with the arc-shaped rack.

[0014] The longitudinal tilting assembly includes a threaded rod, a slider, a linkage rod, and a stepper motor. The threaded rod is rotatably connected to the inner side of the rotating seat, and the slider is slidably connected to the outer side of the rotating seat. The outer side of the threaded rod is threadedly connected to the slider. A stepper motor is mounted on one end of the rotating seat, and the output end of the stepper motor passes through the rotating seat and is fixedly connected to the threaded rod.

[0015] The top of the slider is rotatably connected to a linkage rod, and the far end of the linkage rod is rotatably connected to an adjustment plate. One end of the top of the rotating seat is fixed with an L-shaped limit block, and the top of the L-shaped limit block is fitted with a buffer pad, which contacts the adjustment plate.

[0016] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention can conveniently clamp photovoltaic panels through the cooperation of fixing blocks, clamping plates and pressure bolts; the guide rods on both sides of the clamping plates can ensure accurate sliding without deviation, while the protective pads on the inside of the fixing blocks and clamping plates can buffer the clamping force and avoid damage to the edges of the photovoltaic panels by squeezing, thus taking into account both assembly stability and protection of the photovoltaic panels.

[0018] The reciprocating cleaning mechanism uses a dual-phase servo motor to drive the transmission rod, bevel gear, and adjusting screw, causing the U-shaped cleaning plate to slide back and forth along the surface of the photovoltaic panel. This can promptly remove dust, fallen leaves, and other debris, ensuring the light transmittance of the photovoltaic panel. The protective box can also isolate outdoor rainwater and dust, protecting the core components of the cleaning mechanism, reducing cleaning costs while maintaining power generation efficiency.

[0019] By relying on horizontal and vertical tilting components, it can adapt to the horizontal azimuth changes of the sun rising in the east and setting in the west, and the vertical changes of the sun's altitude angle, respectively, enabling the photovoltaic panel to achieve all-round angle adjustment. This solves the problem that traditional fixed brackets cannot adjust with the sun's azimuth, allowing the photovoltaic panel to fully receive sunlight and significantly improve the photoelectric conversion efficiency.

[0020] The wind speed sensor monitors the wind speed in real time. When the wind speed exceeds the threshold, the linkage tracking mechanism adjusts the wind speed to make the photovoltaic panel parallel to the wind direction in the horizontal direction and reduce the pitch angle in the vertical direction, thereby reducing the windward area. In conjunction with the buffer pad at the top of the L-shaped limit block, the impact force can be buffered and adjusted to avoid rigid collisions. At the same time, the stable photovoltaic panel clamping and guide rod limit can prevent the photovoltaic panel from loosening and shifting due to strong winds, which greatly improves the wind resistance stability and service life of the bracket.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] As shown in the background technology, on the one hand, most of the photovoltaic brackets on the market are fixed structures that can only be fixed at a specific angle and cannot be adjusted according to changes in the sun's position, resulting in photovoltaic panels not receiving sufficient sunlight at different times and limiting photoelectric conversion efficiency; on the other hand, outdoor photovoltaic panels are prone to accumulating dust, fallen leaves and other debris on their surfaces. These pollutants block light and significantly reduce the light transmittance of the photovoltaic panels, further affecting power generation. Traditional cleaning methods mostly rely on manual cleaning, which is not only labor-intensive and costly, but also difficult to achieve timely cleaning in remote photovoltaic power stations and other scenarios.

[0026] Please see Figure 1-7The present invention provides a technical solution: an adaptive wind-resistant photovoltaic support, including a base frame 1, a rotating seat 12 is mounted on the top of the base frame 1, an adjusting plate 2 is rotatably connected to one end of the top of the rotating seat 12, a photovoltaic panel 3 is slidably connected to the top of the adjusting plate 2, a fixing block 24 is fixed to one end of the top of the adjusting plate 2, a clamping plate 10 is slidably connected to the other end of the top of the adjusting plate 2, a pressure bolt 8 is threaded to the other end of the adjusting plate 2, one end of the pressure bolt 8 is rotatably connected to the clamping plate 10, and the fixing block 24 is assembled and connected to the clamping plate 10 and the photovoltaic panel 3.

[0027] The worker places the photovoltaic panel 3 between the fixing block 24 at the top of the adjusting plate 2 and the clamping plate 10. Then, the worker rotates the pressure bolt 8 at the other end of the adjusting plate 2. Because the pressure bolt 8 is threadedly connected to the adjusting plate 2, it moves along its own axis towards the photovoltaic panel 3 during rotation. Since one end of the pressure bolt 8 is rotatably connected to the clamping plate 10, it pushes the clamping plate 10 to slide along the adjusting plate 2 during this process. At this time, the guide rods 11 fixed on both sides of one end of the clamping plate 10 move synchronously with the clamping plate, and the outer side of the guide rods 11 slides against the base frame 1, providing precise guidance for the clamping plate 10 and preventing slippage. As the distance between the clamping plate 10 and the fixing block 24 gradually decreases, the two eventually clamp the photovoltaic panel 3 firmly.

[0028] The inner sides of the fixing block 24 and the clamping plate 10 are equipped with protective pads. Guide rods 11 are fixed on both sides of one end of the clamping plate 10. The outer side of the guide rods 11 is slidably connected to the base frame 1. At the same time, the protective pads on the inner sides of the fixing block 24 and the clamping plate 10 can buffer the clamping force and prevent the edge of the photovoltaic panel 3 from being damaged by squeezing, ensuring the stability of the structure after assembly.

[0029] The outer side of the adjusting plate 2 is provided with a reciprocating cleaning mechanism for cleaning the surface of the photovoltaic panel 3. The reciprocating cleaning mechanism includes an adjusting screw 9, a U-shaped cleaning plate 5, a driven bevel gear 17, a main bevel gear 18, a transmission rod 19, and a two-phase servo motor 20. The adjusting screw 9 is rotatably connected to both sides of the outer side of the adjusting plate 2, and the U-shaped cleaning plate 5 is slidably connected to both sides of the outer side of the adjusting plate 2. The outer side of the adjusting screw 9 is threadedly connected to the U-shaped cleaning plate 5, and the U-shaped cleaning plate 5 is slidably connected to the photovoltaic panel 3.

[0030] The reciprocating cleaning mechanism on the outside of the regulating plate 2 can automatically remove debris from the surface of the photovoltaic panel 3, ensuring light transmittance.

[0031] A protective box 4 is fixed to one end of the adjusting plate 2. A transmission rod 19 is rotatably connected to the inside of the protective box 4. A main bevel gear 18 is fixed to both sides of the transmission rod 19. A driven bevel gear 17 is fixed to one end of the transmission rod 19. The driven bevel gear 17 meshes with the main bevel gear 18. A dual-phase servo motor 20 is installed inside the protective box 4 and in the middle. The output end of the dual-phase servo motor 20 is fixedly connected to the transmission rod 19.

[0032] When cleaning begins, the dual-phase servo motor 20, located in the middle of the protective box 4 fixed to one end of the adjusting plate 2, starts working. Its output drives the fixedly connected transmission rod 19 to rotate. The main bevel gears 18 fixed on both sides of the transmission rod 19 mesh with the driven bevel gear 17 at one end of the transmission rod 19. Therefore, the rotation of the transmission rod 19 is transmitted through the bevel gear meshing, driving the adjusting screws 9, which are rotatably connected to both sides of the outer side of the adjusting plate 2, to rotate synchronously. Because the adjusting screws 9 are threadedly connected to the U-shaped cleaning plate 5 slidably mounted on the outer side of the adjusting plate 2, the rotation of the adjusting screws 9 pushes the U-shaped cleaning plate 5 to slide back and forth along the surface of the photovoltaic panel 3, scraping away dust, fallen leaves, and other debris. The protective box 4 can isolate outdoor rainwater and sand, protecting the dual-phase servo motor 20, bevel gears, and other core components from corrosion.

[0033] Example 2: Please refer to Figure 3-10 The present invention provides a technical solution: an adaptive wind-resistant photovoltaic support, wherein a tracking mechanism for adjusting the orientation of the photovoltaic panel 3 to track sunlight is provided between the base frame 1 and the adjustment plate 2, the tracking mechanism includes a horizontal component and a vertical tilting component, the horizontal component is provided between the base frame 1 and the rotating seat 12, and the vertical tilting component is provided between the rotating seat 12 and the adjustment plate 2.

[0034] The horizontal component includes a second stepper motor 22, a transmission gear 23, and an arc-shaped rack 6. An arc-shaped guide groove is provided at one end of the top of the base frame 1. The inner side of the arc-shaped guide groove is slidably connected to the arc-shaped rack 6. The top end of the arc-shaped rack 6 is rotatably connected to one end of the bottom of the rotating seat 12. The other end of the bottom of the rotating seat 12 is rotatably connected to the base frame 1. A second stepper motor 22 is mounted at one end of the base frame 1. The output end of the second stepper motor 22 passes through the base frame 1 and is fixed with the transmission gear 23. The outer side of the transmission gear 23 is meshed with the arc-shaped rack 6.

[0035] Lateral adjustment is achieved by the horizontal assembly between the base frame 1 and the rotating seat 12. The stepper motor 22 at one end of the base frame 1 is activated, and its output drives the transmission gear 23 to rotate through the base frame 1. Since the transmission gear 23 meshes with the arc-shaped rack 6, and the arc-shaped rack 6 is slidably mounted in the arc-shaped guide groove at the top of the base frame 1, the rotation of the gear drives the arc-shaped rack 6 to slide in an arc along the guide groove. The top of the arc-shaped rack 6 is rotatably connected to one end of the bottom of the rotating seat 12, and the other end of the bottom of the rotating seat 12 is rotatably connected to the base frame 1. Therefore, the sliding of the arc-shaped rack 6 causes the rotating seat 12 to rotate horizontally around its own rotation point with the base frame 1 as the axis. The rotating seat 12 further drives the top adjustment plate 2 and the photovoltaic panel 3 to rotate synchronously, ultimately completing the lateral angle adjustment and ensuring that the photovoltaic panel 3 adapts to changes in the lateral orientation of the sun.

[0036] The longitudinal tilting assembly includes a threaded rod 14, a slider 15, a linkage rod 16, and a stepper motor 21. The threaded rod 14 is rotatably connected to the inner side of the rotating seat 12, and the slider 15 is slidably connected to the outer side of the rotating seat 12. The outer side of the threaded rod 14 is threadedly connected to the slider 15. One end of the rotating seat 12 is equipped with a stepper motor 21, and the output end of the stepper motor 21 passes through the rotating seat 12 and is fixedly connected to the threaded rod 14.

[0037] The longitudinal adjustment is accomplished by the longitudinal tilting assembly between the rotating seat 12 and the adjusting plate 2.

[0038] The stepper motor 21 at one end of the rotating base 12 is started, and its output end passes through the rotating base 12 to drive the threaded rod 14, which is rotatably connected to the inside, to rotate. Because the threaded rod 14 is threadedly engaged with the slider 15, which is slidably assembled on the outside of the rotating base 12, the rotational motion of the threaded rod 14 can be converted into the linear sliding of the slider 15 along the rotating base 12. The linkage rod 16, which is rotatably connected to the top of the slider 15, is rotatably connected to the adjustment plate 2 at its other end. When the slider 15 slides, it pushes or pulls the linkage rod 16, causing the adjustment plate 2 to rotate around its own rotation point relative to the rotating base 12, thereby driving the photovoltaic panel 3 to adjust its pitch angle.

[0039] The top of the slider 15 is rotatably connected to the linkage rod 16. The far end of the linkage rod 16 is rotatably connected to the adjusting plate 2. One end of the top of the rotating seat 12 is fixed with an L-shaped limit block 13. The top of the L-shaped limit block 13 is equipped with a buffer pad, which contacts the adjusting plate 2. In addition, the L-shaped limit block 13 and the buffer pad at the top of the rotating seat 12 can limit the maximum rotation angle of the adjusting plate 2 and prevent the adjusting plate 2 from colliding and being damaged by the limit block.

[0040] One end of the regulating plate 2 is equipped with a wind speed sensor 7.

[0041] Finally, the wind speed sensor 7 mounted on one end of the regulating plate 2 monitors the outdoor wind speed in real time. When the wind speed exceeds the preset safety threshold, the system will link the tracking mechanism to adjust the angle to reduce wind resistance. When the horizontal component is activated, the control rotating seat 12 drives the photovoltaic panel 3 to rotate in a direction parallel to the wind direction, reducing the horizontal windward area.

[0042] When the longitudinal tilting component is activated, the stepper motor 21 drives the threaded rod 14, which in turn drives the slider 15 to slide. This, in turn, adjusts the tilt angle of the adjustment plate 2 via the linkage rod 16, thereby reducing the longitudinal windward area of ​​the photovoltaic panel 3.

[0043] Meanwhile, the buffer pad at the top of the L-shaped limiting block 13 can buffer the impact force when the adjusting plate 2 is adjusted, avoiding rigid collisions of the structure; the fixed block 24 and the clamping plate 10 firmly clamp the photovoltaic panel 3, and together with the limiting effect of the guide rod 11 at one end of the clamping plate 10, it can prevent the photovoltaic panel 3 from loosening or shifting due to strong winds, thus comprehensively improving the wind resistance performance of the bracket.

[0044] 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.
