A reinforcing device for a wind-resistant adjustable photovoltaic support

Abstract

The application discloses a reinforcing device of an anti-wind adjustable photovoltaic support, which comprises a bottom mounting frame, a longitudinal reinforcing frame and a photovoltaic panel, the bottom end of the longitudinal reinforcing frame is fixedly installed at one end of the bottom mounting frame, and the longitudinal reinforcing frame and the bottom mounting frame are arranged in perpendicular to each other, and a supporting assembly is rotatably installed at the top of the bottom mounting frame. The application can automatically and synchronously reduce the overall height of the photovoltaic panel array and make it incline to the supporting frame direction before strong wind comes or when the wind force increases through wind force sensing and a transmission mechanism. The active posture adjustment directly reduces the wind receiving height, wind projection area of the photovoltaic panel and the gap between the panel surface and the ground, thereby effectively weakening the wind pressure on the photovoltaic panel and the wind suction force caused by the airflow acceleration at the bottom, and greatly reducing the dynamic load and overturning risk of the support structure and foundation.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a reinforcement device for a wind-resistant adjustable photovoltaic support. Background Technology

[0002] Currently, a common type of basic support structure widely used in photovoltaic power generation systems is the ordinary wind-resistant photovoltaic bracket. This type of bracket usually adopts a fixed design, and its main body consists of stable ground piles and a metal bracket frame connected to them. During installation, by driving the ground piles deep into the ground or fixing them to the building roof foundation, the bracket provides a reliable installation platform and height above the ground for the photovoltaic panels, thereby effectively adapting to various complex site environments such as land slopes and industrial and commercial factory roofs, and ensuring the basic structural stability of photovoltaic modules for long-term outdoor operation.

[0003] However, the aforementioned conventional fixed photovoltaic (PV) mounting systems have significant technical limitations, particularly in handling complex environments and extreme wind loads. Firstly, the mounting structure and its height above the ground are typically fixed during installation and cannot be adjusted. This results in large and continuous gaps under the PV array when installing on outdoor ground, whether flat or on a slope, to adapt to the terrain, ensure unobstructed airflow at the bottom, or meet minimum ground clearance requirements. When strong winds, especially typhoons and storms, occur, airflow passes through these PV arrays with open bottom spaces. When the photovoltaic panel is in operation, complex aerodynamic effects occur. Specifically, when the wind hits the front of the photovoltaic panel, it is obstructed, the flow velocity decreases, and the static pressure increases. When the airflow passes through the gap at the bottom of the photovoltaic panel or goes around the edge of the panel to reach the back, the leeward side, the flow velocity often increases. According to Bernoulli's principle, the static pressure decreases significantly. This pressure difference between the upper and lower surfaces of the photovoltaic panel is superimposed on the front wind pressure on the panel itself, and together they are transformed into a huge lifting force, i.e., wind suction, that attempts to lift the photovoltaic panel upward. At the same time, it may also generate alternating loads that cause panel flutter.

[0004] When dealing with this problem, the existing fixed support system relies almost entirely on the material strength of its own structure, the tightness of the connection nodes, and the stability of the foundation anchorage to "harden" against these dynamic wind loads. This passive resistance mode has multiple hidden dangers: on the one hand, the bending moment and shear force generated by the huge wind load will be transmitted to the pile foundation through the support, which puts extremely high requirements on the foundation's pull-out resistance and overturning resistance. When the wind force far exceeds the design value, it is very easy to cause the foundation to loosen or overturn entirely.

[0005] On the other hand, continuous and uneven wind pressure will subject the photovoltaic panels to severe alternating stress. Over time, this may lead to loosening of fixing bolts, deformation of the frame, or even cracking of glass laminates or microcracks in the cells, directly affecting power generation efficiency and module lifespan. In addition, the support structure may also undergo plastic deformation or failure of connection parts under repeated strong winds. More importantly, since the support is not adjustable, it is impossible to reduce the windward area or improve the flow field distribution by temporarily changing the tilt angle before severe weather arrives, so as to actively reduce the wind load and can only passively bear it.

[0006] Therefore, how to enhance the dynamic adaptation and mitigation capabilities of photovoltaic support systems to wind loads without sacrificing structural stability, and overcome the lack of regulation function caused by fixed structures, has become an important technical issue for improving the safety and reliability of photovoltaic power plants, especially those located in windy and typhoon-prone areas.

[0007] Therefore, how to provide a reinforcement device for wind-resistant adjustable photovoltaic brackets is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The guide sleeve is close to the transmission gear, and the transmission gear meshes with the toothed plate.

[0019] The beneficial effects of this invention are:

[0020] This invention, through a wind sensing and transmission mechanism, can automatically and synchronously lower the overall height of the photovoltaic panel array before strong winds arrive or when the wind force increases, and tilt it toward the support frame. This active attitude adjustment directly reduces the windward height of the photovoltaic panels, the windward projection area, and the gap between the panel surface and the ground, thereby effectively weakening the wind pressure acting on the photovoltaic panels and the wind suction force generated by the acceleration of the airflow at the bottom from the source, greatly reducing the dynamic load and overturning risk borne by the support structure and foundation.

[0021] Under strong wind conditions, the system drives the front and rear rows of photovoltaic panels to form an alternating tilting posture. This layout breaks the continuous and open through gaps formed under the traditional fixed array, which can disrupt and divide the concentrated airflow passing through the array, avoiding the continuous high-speed "through wind" effect. At the same time, the tilt of the front row of photovoltaic panels can provide some wind shadow zone protection for the rear row. This way of changing the shape of the airflow channel as a whole effectively suppresses the intensification of airflow and vortex shedding, thereby significantly improving the aerodynamic stability and wind resistance safety of the entire photovoltaic array in strong wind environments.

[0022] The system is driven entirely by natural wind power. Wind energy is converted into mechanical energy through wind power transmission components, which in turn drives the height adjustment mechanism. The entire process requires no external power supply or human intervention, achieving true self-sensing, self-driving, and self-adjustment. This not only reduces the system's operation and maintenance costs and energy consumption, but more importantly, it ensures that the system can still automatically activate its protection mechanism in extreme weather such as typhoons and storms that cause power outages or prevent people from approaching the area. This improves the applicability and reliability in harsh and remote environments.

[0023] The angle adjustment capability provided by this invention is not only used for wind resistance, but can also be applied to daily operation optimization. In non-windy weather, all photovoltaic panels can be adjusted to a specific height and position through manual control, so that their front or back is better aligned with the prevailing wind direction. This is conducive to using natural wind to efficiently convect and dissipate heat from the photovoltaic panels, reducing the operating temperature and improving power generation efficiency. At the same time, it can also blow on the panel surface to achieve a certain degree of self-cleaning function, removing light dust and fallen leaves, which can improve the overall operating efficiency of the system.

[0024] The support components employ a parallelogram linkage mechanism to ensure that the photovoltaic panel's tilt angle remains constant during height changes, maintaining a stable power generation posture. The adjusting screw and internal threaded block are designed with a transmission separation mechanism, automatically disengaging after adjustment to avoid over-adjustment or mechanism overload. The clutch component ensures that power is transmitted only when the wind speed reaches a set threshold, preventing malfunctions in light winds. In addition, the hollow frame design enhances airflow, and the trough plate, protective frame, and other structures effectively protect the transmission components, improving adaptability to outdoor environments and the overall system lifespan.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0040] Example 1

[0041] refer to Figures 1-12In this embodiment, the system includes a bottom mounting frame 1, a longitudinal reinforcing frame 2, and a photovoltaic panel 3. The bottom end of the longitudinal reinforcing frame 2 is fixedly mounted to one end of the bottom mounting frame 1, and the longitudinal reinforcing frame 2 and the bottom mounting frame 1 are perpendicular to each other. Both the bottom mounting frame 1 and the longitudinal reinforcing frame 2 are hollowed out. Figure 1 As shown, to increase airflow, a support assembly 4 is rotatably mounted on the top of the bottom mounting frame 1. The photovoltaic panel 3 is fixedly mounted on the top of the support assembly 4, supporting the photovoltaic panel 3 at a high position and maintaining it at a certain angle towards the sun. To adapt to the terrain, ensure unobstructed bottom access, or meet minimum ground clearance requirements, a large and continuous through gap is often formed below the photovoltaic panel 3 array, such as... Figure 1 As shown, the arrangement of at least two sets of photovoltaic panels 3 in front and behind each other will not block sunlight, and the space utilization rate is also high. The support component 4 includes a mounting base 9, two sets of parallel support plates 10 and a top support plate 11. The mounting base 9 is fixedly installed on the top of the bottom mounting frame 1 near the outermost part. The two sets of parallel support plates 10 are rotatably connected to the top of the mounting base 9. The top of the two sets of parallel support plates 10 is rotatably connected to the end face of the top support plate 11. The two sets of parallel support plates 10, the top support plate 11 and the bottom mounting frame 1 form a parallelogram, which is used to tilt synchronously when the support plates 10 move. Moreover, when the support plates 10 are tilted, the top support plate 11 can be kept stable and parallel to the bottom mounting frame 1. Since the top support plate 11 is stable, the photovoltaic panel 3 is also stable when tilted.

[0042] The support assembly 4 also includes a support rod 12 and a connecting seat 13. The support rod 12 is fixedly installed on the top of the top support plate 11, and the connecting seat 13 is fixedly installed on the bottom of the photovoltaic panel 3. The connecting seat 13 is fixedly installed on the top of the support rod 12. Here, both the support rod 12 and the connecting seat 13 are installed at the top position of the top support plate 11 to achieve stable installation and movement stability of the photovoltaic panel 3. In order to further reinforce the installation, a rope hole is opened between the support rod 12 and the connecting seat 13. A top reinforcement rope connected end to end is movably installed in the rope hole.

[0043] A height adjustment assembly 5 for adjusting the height of the photovoltaic panel 3 is fixedly installed on the side of the bottom mounting frame 1. The height adjustment assembly 5 is rotatably mounted on the side of the support assembly 4. The height adjustment assembly 5 includes a diagonal pull rod 14 that pulls the support frame plate 10 to rotate around the mounting base 9, a groove plate 15, an adjusting screw 16 installed in the groove plate 15, an internal thread block 17, and a first bevel gear 18. One end of the diagonal pull rod 14 is rotatably mounted on both sides of the support frame plate 10, and the other end of the diagonal pull rod 14 is fixedly mounted with a connecting shaft. The other end of the connecting shaft is rotatably mounted with the internal thread block 17. On the side, the slot plate 15 is fixedly installed on the end face of the bottom mounting frame 1. The adjusting screw 16 is rotatably installed inside the slot plate 15. The slot plate 15 elevates the adjusting screw 16 to a certain distance from the ground, which is to prevent weeds or reptiles from affecting the normal movement of the adjusting screw 16 outdoors. Moreover, the slot plate 15 is open on the side, not on the top, which further prevents rainwater from corroding the adjusting screw 16 and improves its durability. The internal threaded block 17 is movably connected inside the slot plate 15 and threaded onto the surface of the adjusting screw 16. The first bevel gear 1... 8 is fixedly installed on the surface of the adjusting screw 16 near the longitudinal reinforcing frame 2. One end of the height adjusting component 5 is engaged with a side transmission component 6 for driving the height adjusting component 5. The side transmission component 6 is located on the side of the longitudinal reinforcing frame 2 and includes a side protective frame 19, a side transmission shaft 20, a bottom bevel gear 21, a top bevel gear 22, a second bevel gear 23, and a drive shaft 24. The side protective frame 19 is fixedly installed on the side of the longitudinal reinforcing frame 2, and the side transmission shaft 20 is rotatably installed inside the side protective frame 19. The bottom bevel gear 21 is fixedly connected to the bottom end of the side drive shaft 20, the top bevel gear 22 is fixedly installed on the top end of the side drive shaft 20, the drive shaft 24 is rotatably installed on the top of the longitudinal reinforcement frame 2, the second bevel gear 23 is fixedly installed on the end face of the drive shaft 24, the second bevel gear 23 meshes with the top bevel gear 22, the bottom bevel gear 21 meshes with the first bevel gear 18, the top of the longitudinal reinforcement frame 2 is rotatably installed with a wind power transmission assembly 7, and the top of the wind power transmission assembly 7 is fixedly installed with a fan blade 8 that rotates by wind power.

[0044] The working principle of Example 1 is as follows: When encountering a strong airflow, the wind speed is relatively high. The high-speed airflow blows the fan blade 8, which rotates continuously through the wind power transmission assembly 7. Then, the rotation of the wind power transmission assembly 7 drives the drive shaft 24 to rotate. The rotation of the drive shaft 24 drives the second bevel gear 23 to rotate. The rotation of the second bevel gear 23 drives the top bevel gear 22 to rotate. The rotation of the top bevel gear 22 drives the side transmission shaft 20 to rotate. The rotation of the side transmission shaft 20 drives the first bevel gear 18 to rotate through the bottom bevel gear 21. The rotation of the first bevel gear 18 drives the adjusting screw 16 to rotate. The rotation of the adjusting screw 16 drives the inner screw... The threaded block 17 moves towards the side closer to the longitudinal reinforcing frame 2. The movement of the internal threaded block 17 pulls the entire parallelogram-shaped support assembly 4 through the diagonal brace. In this way, while the support assembly 4 tilts towards the longitudinal reinforcing frame 2, it does not change the tilt angle of the photovoltaic panel 3. It only tilts and moves the photovoltaic panel 3 towards the longitudinal reinforcing frame 2, changing the distance between the photovoltaic panel 3 and the ground. This causes the photovoltaic panel 3, which is at a high position, to fall towards the ground, reducing the distance between the photovoltaic panel 3 and the ground. In this way, a larger airflow will blow over the photovoltaic panel 3. Since the photovoltaic panel 3 is close to the ground, the airflow between the two sets is smaller and the photovoltaic panel 3 is stable.

[0045] Example 2

[0046] refer to Figures 1-12 The structures of the bottom mounting frame 1, longitudinal reinforcement frame 2, support component 4, height adjustment component 5, side transmission component 6, photovoltaic panel 3, wind power transmission component 7, and fan blade 8 in this embodiment are the same as those described in embodiment 1, and will not be repeated here.

[0047] When encountering strong airflow, the high-speed airflow blows the fan blades 8, causing them to rotate. This rotation drives the wind power transmission assembly 7, which in turn drives the drive shaft 24. The drive shaft 24 rotates, which in turn drives the second bevel gear 23. The second bevel gear 23, through the top bevel gear 22, drives the side drive shaft 20. The side drive shaft 20, through the bottom bevel gear 21, drives the first bevel gear 18. The first bevel gear 18, in turn, drives the adjusting screw 16. The adjusting screw 16, in turn, moves the internal threaded block 17 closer to the longitudinal reinforcement frame 2, pulling the diagonal brace. The movement of the diagonal brace, in turn, moves the internal threaded block 17, which in turn pulls the entire parallelogram-shaped support assembly 4. In this way, the support assembly 4 tilts towards the longitudinal reinforcement frame 2 without changing the tilt angle of the photovoltaic panel 3. The photovoltaic panels 3 are tilted and moved towards the longitudinally reinforced frame 2, thus changing the front and rear states of the photovoltaic panels 3. This causes the front and rear rows of photovoltaic panels 3 to form an alternating overturning posture in strong winds. This not only reduces the overall wind exposure height of each photovoltaic panel 3, but also creates segmented, discontinuous airflow channels between the arrays through the difference in tilt angles between the front and rear panels. This layout can effectively disrupt and weaken the concentrated airflow passing under the photovoltaic array, avoiding the generation of continuous, high-speed through-wind effects. This significantly reduces the dynamic impact and torsion of wind load on the overall structure. At the same time, the tilt of the front row of photovoltaic panels 3 towards the ground can provide partial wind shadow protection for the rear row of photovoltaic panels 3, further stabilizing the airflow environment on the rear panel surface. This allows the photovoltaic array to improve its overall wind resistance stability and safety by dynamically adjusting the spatial posture of the array in strong winds.

[0048] Secondly, in order to achieve the separation operation and prevent the internal threaded block 17 from moving continuously, the surface of the adjusting screw 16 is provided with two sets of threads corresponding to the internal threaded block 17. The two sets of threads are arranged in the same direction and are convex threads. There is a gap between the two sets of threads that is larger than the width of the internal threaded block 17. When the internal threaded block 17 is separated from the thread, it can still slide and fit on the smooth surface of the adjusting screw 16. Therefore, after the photovoltaic panel 3 is adjusted, the internal threaded block 17 will separate from the thread and slide and fit on the surface of the adjusting screw 16 to achieve the separation purpose. Even if the adjusting screw 16 continues to rotate, it will no longer drive the internal threaded block 17 to move. Here, a baffle plate is set inside the slot plate 15 to block each internal threaded block 17 that is separated from the adjusting screw 16. In addition, an elastic pad is fixed on the side of the baffle plate near the internal threaded block 17, which contracts under the pressure of the internal threaded block 17.

[0049] Example 3

[0050] refer to Figures 1-12 The structures of the bottom mounting frame 1, longitudinal reinforcement frame 2, support component 4, height adjustment component 5, side transmission component 6, photovoltaic panel 3, wind power transmission component 7, and fan blade 8 in this embodiment are the same as those described in embodiment 1, and will not be repeated here.

[0051] When the drive shaft 24 drives the adjusting screws 16 of each photovoltaic panel 3 to rotate synchronously through the transmission system, multiple photovoltaic panels 3 can be tilted at the same amplitude and direction. In summer when the temperature is high or the panels are dusty, all photovoltaic panels 3 can be controlled to face the same angle as the prevailing wind direction. At this time, the airflow can blow on the back of the photovoltaic panel 3 through the hollow frame and the front edge at the optimal angle, forming efficient convection heat dissipation, reducing the operating temperature of the photovoltaic panel 3 and improving power generation efficiency. At the same time, the uniform wind can effectively remove light dust and fallen leaves from the panel surface, achieving a certain degree of self-cleaning function. This effect focuses on using the structural adjustability to optimize the heat dissipation and cleaning of the photovoltaic panel 3 in the daily operation environment, rather than being limited to wind protection, thereby improving the overall efficiency of the system under normal weather conditions.

[0052] Example 4

[0053] refer to Figures 1-12 In this embodiment, the wind power transmission assembly 7 includes a fixed support cylinder 25, a top cover 26, a movable shaft 27, a third bevel gear 28, two sets of fourth bevel gears 29, a fifth bevel gear 30, a rotating shaft 31, a tail plate 32, and a clutch assembly 33. The fixed support cylinder 25 is fixedly installed on the top of the longitudinal reinforcement frame 2. The drive shaft 24 is rotatably installed on the fixed support cylinder 25. The third bevel gear 28 is fixedly sleeved on the surface of the drive shaft 24. The movable shaft 27 is rotatably installed inside the fixed support cylinder 25. One set of fourth bevel gears 29 is fixedly installed at the bottom end of the movable shaft 27, and the other set of fourth bevel gears 28... Wheel 29 is fixedly installed on the top of movable shaft 27, top cover 26 is rotatably installed on the top of fixed support cylinder 25, rotating shaft 31 is rotatably installed on top cover 26 and perpendicular to movable shaft 27 to achieve effective transmission, fifth bevel gear 30 is fixedly installed on the surface of rotating shaft 31, third bevel gear 28 meshes with a set of fourth bevel gears 29, fifth bevel gear 30 meshes with another set of fourth bevel gears 29, tail plate 32 is fixedly installed on the surface of top cover 26, clutch assembly 33 is fixedly installed on the end face of rotating shaft 31, and fan blade 8 is fixedly installed on the surface of clutch assembly 33.

[0054] The working principle of this embodiment is as follows: the rotation of the fan blade 8 drives the rotating shaft 31 and the clutch assembly 33 to rotate. When the rotation speed of the fan blade 8 accelerates too quickly, it will push the clutch assembly 33, which is set and adjusted, to rotate synchronously. The rotation of the clutch assembly 33 is connected by centrifugal force, which then drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the fifth bevel gear 30 to rotate. The rotation of the fifth bevel gear 30 drives a set of fourth bevel gears 29 to rotate. The rotation of the fourth bevel gears 29 drives the movable shaft 27 and another set of fourth bevel gears 29 to rotate synchronously. The rotation of the other set of bevel gears drives the third bevel gear 28 to rotate, thereby driving the drive shaft 24 to rotate through the third bevel gear 28. Here, the two sets of fourth bevel gears 29 and fifth bevel gears 30 have adjusted transmission ratios to increase torque. Therefore, this setting will greatly improve the power of the drive shaft 24. Secondly, the top cover 26 is designed to support the fourth bevel gears. The fourth bevel gear 29 and the fifth bevel gear 30 are effectively protected, while the fixed support cylinder 25 also effectively protects the connection between the fourth bevel gear 29 and the fifth bevel gear 30, the movable shaft 27, and the connection between the fourth bevel gear 29 and the third bevel gear 28. The top cover 26 is rotatably mounted on the top of the fixed support cylinder 25, and the extended axis of the movable shaft 27 coincides with the axis of the top cover 26. In this way, when the fan blade 8 is blown by the wind, the tail plate 32 drives the fan blade 8, the clutch assembly 33, the rotating shaft 31, and the fifth bevel gear 30 to move around the fourth bevel gear 29 and the movable shaft 27. This allows the direction of the fan blade 8 to be changed according to the wind direction, thereby effectively generating power according to the airflow and avoiding the fan blade 8 being effective only for one side of the wind. This allows for the measurement of wind direction. In actual use, it can also be adjusted according to the climate environment, and the top cover 26 can be fixed to face the same direction to cope with some special environments.

[0055] Example 5

[0056] refer to Figures 1-12In this embodiment, the clutch assembly 33 includes a connecting cylinder 34, a rotating cylinder 35, a fixed lever 36, a limiting sleeve 37, a movable rod 38, a centrifugal block 39, a movable lever 40, and a spring 41. The connecting cylinder 34 is fixedly installed on the end face of the rotating shaft 31, the fixed lever 36 is fixedly installed on the inner wall of the connecting cylinder 34, the rotating cylinder 35 is rotatably sleeved on the surface of the rotating shaft 31, the limiting sleeve 37 is fixedly installed on the end face of the rotating cylinder 35, the movable rod 38 is movably connected inside the limiting sleeve 37, and the movable lever 40 is fixedly installed on the movable lever 41. One end of the rod 38 is close to the inside of the connecting cylinder 34. The centrifugal block 39 is fixedly installed at the other end of the movable rod 38. The spring 41 is movably sleeved on the surface of the movable rod 38 between the limiting sleeve 37 and the movable lever 40. There are two sets of fixed lever 36, limiting sleeve 37, movable rod 38, centrifugal block 39, movable lever 40 and spring 41. The two sets of fixed lever 36, limiting sleeve 37, movable rod 38, centrifugal block 39, movable lever 40 and spring 41 are arranged in a ring array with the center of the rotating cylinder 35 as the array center.

[0057] Both the rotating cylinder 35 and the connecting cylinder 34 are cylindrical, and a flow divider 42 is fixedly installed on the end face of the rotating cylinder 35.

[0058] The working principle of this embodiment is as follows: When the fan blade 8 rotates, it drives the rotating cylinder 35 to rotate around the connecting cylinder 34. The rotation of the rotating cylinder 35 drives the limiting sleeve 37, the movable rod 38, the centrifugal block 39, the movable lever 40, and the spring 41 to rotate synchronously. Under rotation, the centrifugal block 39 is thrown outward by centrifugal force and drives the movable rod 38 to move along the limiting sleeve 37. The movement of the movable rod 38 drives the movable lever 40 to move and squeeze the spring 41. When the movable lever 40 moves into the range of the fixed lever 36, it will be fixed by the fixed lever 36. When the fixed block 36 rotates, the movable block 40 continues to rotate, which in turn drives the fixed block 36 to rotate. The rotation of the fixed block 36 drives the connecting cylinder 34 to rotate, which in turn drives the rotating shaft 31 to rotate. When the wind speed is low, the rotation speed of the fan blade 8 also decreases. When the rotation speed of the fan blade 8 is low, it will push the movable block 40 inward under the elastic force of the spring 41, so that the movable block 40 separates from the fixed block 36, thereby achieving the effect of clutch engagement and disengagement. This avoids wind power transmission under low wind speed and only allows transmission operation in some special environments with strong winds.

[0059] Example 6

[0060] refer to Figures 1-12In this embodiment, a pull rope 43 is wound around the connection between the mounting base 9 and the support frame plate 10, the connection between the two sets of support frame plates 10 and the top support plate 11, the connection between the support frame plate 10 and the diagonal tie rod 14, and the connection between the diagonal tie rod 14 and the internal thread block 17. A third guide wheel 44 is fixedly installed on the top of the mounting base 9 corresponding to the pull rope 43. The pull rope 43 is slidably sleeved on the surface of the third guide wheel 44. The number of support components 4, photovoltaic panels 3 and height adjustment components 5 is not less than two sets. The number of pull ropes 43 matches the number of support components 4, photovoltaic panels 3 and height adjustment components 5. Two sets of first guide wheels 45 are symmetrically fixedly installed on the side of the longitudinal reinforcement frame 2 corresponding to the pull rope 43. Two sets of second guide wheels 46 are symmetrically slidably installed on the surface of the longitudinal reinforcement frame 2 through the sliding components. The two ends of the pull rope 43 closest to the longitudinal reinforcement frame 2 pass through the first guide wheel 45 and the second guide wheel 46 at the corresponding positions and are fixedly connected to each other. The two ends of the remaining pull rope 43 are fixedly connected to the pull rope 43 closest to the longitudinal reinforcement frame 2.

[0061] There are a total of two sets of support components 4. The ropes 43 on the two sets of support components 4 are connected end to end. The ropes 43 that are far away from the longitudinal reinforcement frame 2 will follow the following... Figure 1 and Figure 4 As shown, after being wrapped, it is fixedly connected by a pull rope 43 near the longitudinal reinforcing frame 2, as shown. Figure 4 As shown, after installation, only one set of pull ropes 43 needs to be pulled to move the other set of pull ropes 43.

[0062] The sliding assembly includes a slide plate 47, a slide rail 48, and a connecting plate 49. The slide rail 48 is fixedly installed on the side of the longitudinal reinforcing frame 2. The slide plate 47 is slidably connected inside the slide rail 48. The surface of the slide plate 47 is fixedly connected to the end face of the second guide wheel 46. The connecting plate 49 is fixedly installed on the surface of the slide plate 47. The top of the connecting plate 49 has a downward through-hole that extends through the top and bottom of the connecting plate 49. A lifting rod 50 is movably connected inside the through-hole. A reinforcing plate 51 is fixedly installed at the top and bottom of the lifting rod 50. A toothed plate 52 is fixedly installed at the top of the reinforcing plate 51 at the top of the lifting rod 50. A first spring 53 is movably sleeved between the surface of the pull rod 50 below the connecting plate 49 and the reinforcing plate 51 at the bottom of the pull rod 50. A guide sleeve 54 is fixedly installed on the surface of the longitudinal reinforcing frame 2 corresponding to the toothed plate 52. The guide sleeve 54 is movably sleeved on the surface of the toothed plate 52. A transmission gear 55 is fixedly installed on the top of the longitudinal reinforcing frame 2 corresponding to the toothed plate 52. A drive gear 56 is fixedly sleeved on the surface of the drive shaft 24 corresponding to the transmission gear 55. The drive gear 56 meshes with the transmission gear 55. The guide sleeve 54 is close to the transmission gear 55. The transmission gear 55 and the toothed plate 52 mesh with each other.

[0063] The working principle of this embodiment is as follows: The drive shaft 24 rotates while simultaneously driving the drive gear 56. The rotation of the drive gear 56, through the transmission gear 55, causes the toothed plate 52 to move upwards along the guide sleeve 54. The movement of the toothed plate 52 causes the reinforcing plate 51 to move upwards. The upward movement of the reinforcing plate 51 then causes the lifting rod 50 to move upwards and compress the first spring 53. The compression of the first spring 53 adjusts the tension of the pull rope 43 caused by the movement of the diagonal brace and the tilting of the support frame plate 10, ensuring that the tension of the pull rope 43 is maintained even when tilted. After the compression of the first spring 53 stabilizes, it pushes the connecting plate 49 in the opposite direction. Moving upwards, the connecting plate 49 moves upwards, which in turn drives the sliding plate 47 to move upwards along the slide rail 48. The upward movement of the sliding plate 47 drives the second guide wheel 46 to move upwards, and the upward movement of the second guide wheel 46 drives the pull rope 43 to move upwards. This ensures that the tension of the pull rope 43 is maintained when the photovoltaic panel 3 is tilted and adjusted, thus improving the overall stability of the support structure. Secondly, the pull rope 43 is connected end to end and can move, which avoids the pull rope 43 being stressed on one side or loose on the other side. The purpose of the pull rope 43 being connected end to end is to adjust its own tension by sliding along the first guide wheel 45 and the second guide wheel 46 when it is pulled.

[0064] Secondly, if the wind continues to blow, the toothed plate 52 will move upward to the desired state and then separate from the transmission gear 55. Therefore, even if the transmission gear 55 continues to drive, the toothed plate 52 will not move upward. The separation position here matches the separation position of the adjusting screw 16 and the internal thread block 17.

[0065] Example 7

[0066] refer to Figures 1-12 In this embodiment, one end of a set of adjusting screws 16 passes through the longitudinal reinforcing frame 2 and extends to the other side of the longitudinal reinforcing frame 2. A ratchet 57 is fixedly sleeved on the surface of the other side of the longitudinal reinforcing frame 2 at the position of the adjusting screws 16. A pawl 58 is rotatably mounted on the surface of the longitudinal reinforcing frame 2. A torsion spring is movably sleeved at the connection between the pawl 58 and the longitudinal reinforcing frame 2. One end of the torsion spring is fixedly connected to the pawl 58, and the other end of the torsion spring is fixedly connected to the surface of the longitudinal reinforcing frame 2. One end of the pawl 58 is movably engaged with the surface of the ratchet 57.

[0067] The tail end of the pawl 58 is movably connected to a positioning head. The surface of the longitudinally reinforcing frame 2 has an insertion hole corresponding to the positioning head. When the pawl 58 is separated from the ratchet 57, the positioning head is movably inserted into the insertion hole.

[0068] The working principle of this embodiment is as follows: To prevent it from rotating in the opposite direction, a ratchet 57 and a pawl 58 are added. The adjusting screw 16 can only rotate in the same direction when the wind blows. The rotation of the adjusting screw 16 will drive the ratchet 57 to rotate. The rotation of the ratchet 57 will squeeze the pawl 58 to separate it from the ratchet 57. When the ratchet 57 rotates in the opposite direction, it will be stuck by the pawl 58. When maintenance is required after a strong wind, the pawl 58 needs to be rotated to drive the positioning head into the socket to separate the pawl 58 from the ratchet 57. Then, the adjusting screw 16 can be rotated by the manual knob at the adjusting screw 16.

[0069] This technical solution is used to deal with strong winds, since strong winds do not occur frequently. It is mainly used to deal with emergencies and the resulting unnecessary property damage and damage to power equipment, so there are few cases requiring human intervention.

[0070] The working principle of this invention is:

[0071] When encountering strong winds, the airflow drives the fan blades 8 to rotate, and the wind power transmission assembly 7 transmits the rotational power to the drive shaft 24. The rotation of the drive shaft 24, on the one hand, drives the adjusting screw 16 to rotate through the side transmission assembly 6, causing the threaded internal thread block 17 to move along the groove plate 15 towards the longitudinal reinforcement frame 2. This, in turn, pulls the parallelogram support assembly 4, composed of the mounting base 9, support frame plate 10, and top support plate 11, towards the longitudinal reinforcement frame 2 through the diagonal tie rod 14. This process simultaneously reduces the ground clearance of multiple photovoltaic panels 3 and makes them form a staggered wind-resistant posture, while the power generation tilt angle of the photovoltaic panels 3 remains unchanged. On the other hand, The drive shaft 24 lifts the tensioning component through the gear and rack mechanism, driving the second guide wheel 46 to move to compensate and keep the tensioning rope 43 system of each support component 4 in a state of tension, ensuring the stability of the overall structure during dynamic adjustment. When the photovoltaic panel 3 tilts to the preset safe position, the internal thread block 17 slides from the threaded section of the adjusting screw 16 into the smooth section to achieve transmission separation. At the same time, the ratchet 57 and pawl 58 mechanism prevent the screw from reversing, locking the system in a wind-resistant state. After the wind weakens, manual intervention is required to reset the system, so that the internal thread block 17 re-engages the thread and rotates the adjusting screw 16 in the opposite direction, thereby restoring the photovoltaic panel 3 to its normal working height and position.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
