Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and more specifically, to an adaptive adjustment device for a wind-pressure resistant photovoltaic support. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, is increasingly widely used. Photovoltaic panels are typically fixed to outdoor locations such as rooftops and ground surfaces using support structures, and are exposed to the natural environment for extended periods. Wind load is one of the main environmental loads affecting the safety and stability of photovoltaic support structures. Strong winds, especially those blowing from the front or back of the photovoltaic panels, can create significant wind pressure on the panel surface, potentially damaging the panels themselves and causing the entire support structure to sway, deform, or even overturn, posing serious safety hazards.

[0003] Currently, common fixed-tilt photovoltaic (PV) supports have a simple structure but lack the ability to adaptively adjust to wind loads, posing significant risks in strong winds. While some adjustable-angle PV supports exist, their adjustment largely relies on active drive mechanisms such as electric actuators and hydraulic cylinders, requiring the integration of wind speed sensors and control systems. These solutions are complex, costly, and dependent on external power and control signals, potentially leading to power supply or control system failures in severe weather, thus requiring improved reliability.

[0004] To address this, an adaptive adjustment device for wind-pressure resistant photovoltaic supports is proposed. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide an adaptive adjustment device for a wind-pressure resistant photovoltaic support, which can automatically adjust the angle of the photovoltaic panel when subjected to strong winds, thereby reducing the wind force on the photovoltaic panel, preventing damage to the device, and improving the durability of the device.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An adaptive adjustment device for a wind-pressure resistant photovoltaic support includes a mounting base, with support frames on both sides of the upper end of the mounting base. A rotating rod is rotatably connected to the upper end of the support frame, and a clamp is fixedly connected to one side of the rotating rod. A photovoltaic panel is fixedly connected to the opposite side of the two clamps. A leveling component is provided inside the support frame.

[0008] The leveling assembly includes a circular block fixedly connected to one side of the support frame. A return spring is fixedly connected inside the circular block. One side of the return spring is fixedly connected to the wall of the rotating rod. An air shell is fixedly connected to the upper end of the mounting base. Piston plates are slidably connected to the front and rear positions inside the air shell. Connecting rods are evenly fixedly connected to the opposite sides of the two piston plates. The wall of the connecting rod is slidably connected to the air shell. A wind plate is fixedly connected to one end of the connecting rod. A vertical block is fixedly connected to the upper end of the air shell. A piston block is slidably connected to the upper end of the vertical block. A push rod is fixedly connected to the upper end of the piston block. A push plate is provided at the upper end of the push rod.

[0009] Preferably, both of the two air plates have arc-shaped grooves on their opposite sides.

[0010] Preferably, limit blocks are fixedly connected to both the front and rear positions inside the gas shell.

[0011] Preferably, a toothed plate is fixedly connected to the lower end of the piston block, a rod is rotatably connected inside the vertical block, a gear is fixedly connected to the rod wall of the rod, the gear meshes with the toothed plate, support blocks are fixedly connected to both sides of the vertical block, a constant force spring is fixedly connected inside the support block, and the inside of the constant force spring is fixedly connected to the rod wall of the rod.

[0012] Preferably, a movable rod is slidably connected inside the top rod, the upper end of the movable rod is rotatably connected to the lower end of the push plate, a first spring is fixedly connected to the lower end of the movable rod, and L-shaped plates are fixedly connected to both the front and rear positions of the upper end of the top rod.

[0013] Preferably, a rotating roller is rotatably connected to the upper end of the L-shaped plate.

[0014] Preferably, air holes are provided at both the front and rear positions of the air shell.

[0015] Preferably, a rotating block is fixedly connected to the wall of the rotating rod, an arc-shaped block is slidably connected inside the rotating block, a second spring is fixedly connected to one end of the arc-shaped block, the other end of the arc-shaped block is partially embedded inside the support frame, and a ball is movably disposed at one end of the arc-shaped block.

[0016] Preferably, a liquid cylinder is fixedly connected to one side of the circular block, an orifice plate is fixedly connected to the wall of the rotating rod, and the liquid cylinder is filled with hydraulic oil.

[0017] Preferably, the liquid cylinder is internally connected to a threaded rod, the rod wall of which is threaded with a toothed block, the inside of the rotating rod is provided with a slot, the slot is provided with a limit groove, and the upper and lower positions of the inner wall of the liquid cylinder are fixedly connected with sliding rods, the rod wall of the sliding rod is slidably connected to the inside of the toothed block.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) When strong wind blows from the front or back of the photovoltaic panel, the wind will push the corresponding wind plate. Through the air shell, piston plate, piston block, push rod, etc., the thrust is converted into the upward motion of the push rod. The push rod acts on the lower edge of the photovoltaic panel through the push plate, forcing the photovoltaic panel to rotate around the rotating rod to a horizontal state. In the horizontal state, the contact area between the photovoltaic panel and the wind is greatly reduced, thereby significantly reducing the direct impact of wind pressure on the photovoltaic panel and the entire support structure. This effectively avoids structural damage that may be caused by strong winds and improves the reliability and durability of the device in severe weather. This component does not require the use of electric drive components and has a stronger applicability to work.

[0020] (2) The rotating rod drives the orifice plate to rotate in the hydraulic cylinder filled with hydraulic oil, and the hydraulic oil generates resistance to the movement of the orifice plate. This ensures that the photovoltaic panel will not move too fast due to instantaneous force when rotating (whether it is laid flat or reset), and has a buffering effect on sudden gusts of wind. Only continuous wind force can drive the photovoltaic panel to complete the angle adjustment, preventing frequent and violent shaking.

[0021] (3) A threshold triggering mechanism is formed by the cooperation between the arc-shaped block inside the rotating block and the second spring. The photovoltaic panel will only start to rotate when the wind force reaches a certain level and the torque applied to the rotating rod is sufficient to overcome the resistance of the second spring and retract the arc-shaped block. This allows the device to "ignore" small wind forces, maintain the stability of the photovoltaic panel under light wind conditions, and avoid unnecessary adjustments.

[0022] (4) The push rod and the push plate are connected by a moving rod and a first spring, and the push plate can rotate relative to the moving rod. During operation, the push plate first contacts the lower surface of the photovoltaic panel. As the push rod continues to rise, the moving rod retracts relative to the push rod, compressing the first spring. At the same time, the L-shaped plate at the upper end of the push rod and the roller on it push upward, causing the push plate to gradually change to a horizontal state and completely fit against the bottom surface of the photovoltaic panel. This design ensures that the thrust is evenly applied to a region of the photovoltaic panel, rather than concentrated at a certain point, effectively avoiding the risk of the photovoltaic panel (especially the glass components) cracking or developing microcracks due to excessive local stress during adjustment, and improving operational safety.

[0034] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 9An adaptive adjustment device for a wind-pressure resistant photovoltaic support includes a mounting base 5. Support frames 1 are provided on both sides of the upper end of the mounting base 5. The support frames 1 are made of stainless steel and have high support strength. A rotating rod 10 is rotatably connected to the upper end of the support frame 1. The rotating rod 10 can rotate inside the support frame 1. A clamp 3 is fixedly connected to one side of the rotating rod 10. The clamp 3 is used to fix a photovoltaic panel 2. Under the action of the rotating rod 10, it can rotate, thereby allowing the photovoltaic panel 2 to rotate. The photovoltaic panel 2 is fixedly connected to the opposite sides of the two clamps 3. A leveling component is provided inside the support frame 1. The leveling component allows the photovoltaic panel 2 to be leveled, reducing the contact area with the wind.

[0036] The leveling assembly includes a circular block 9 fixedly connected to one side of the support frame 1. A return spring 15 is fixedly connected inside the circular block 9. One side of the return spring 15 is fixedly connected to the wall of the rotating rod 10. When the rotating rod 10 rotates relative to the support frame 1, the rotating rod 10 causes the return spring 15 to deform. Thus, when the rotating rod 10 is not subjected to any other force at the rear, the rotating rod 10 returns to its original position under the action of the return spring 15. An air shell 4 is fixedly connected to the upper end of the mounting base 5. Piston plates 23 are slidably connected to the front and rear positions inside the air shell 4. The piston plates 23 can move inside the air shell 4. Connecting rods 22 are evenly fixedly connected to the opposite sides of the two piston plates 23. The connecting rods 22 move synchronously with the piston plates 23, and the wall of the connecting rod 22 slides against the air shell 4. The connecting rod 22 can slide back and forth relative to the air shell 4. One end of the connecting rod 22 is fixedly connected to the wind plate 6, which is used to receive wind power. Under the action of wind power, the wind plate 6 moves. The upper end of the air shell 4 is fixedly connected to the vertical block 7. The upper end of the vertical block 7 is slidably connected to the piston block 25. The piston block 25 can move up and down inside the vertical block 7. The upper end of the piston block 25 is fixedly connected to the top rod 26. The piston block 25 and the top rod 26 move synchronously. The upper end of the top rod 26 is provided with a push plate 21. The up and down movement of the top rod 26 can drive the push plate 21 to move up and down. Air holes 24 are opened at the front and rear positions of the air shell 4. The air holes 24 ensure that the air pressure on the opposite side of the two piston plates 23 remains constant, thus not interfering with the movement of the piston plates 23.

[0037] When it's windy, it's important to note that during operation, wind affecting the entire device only occurs when it blows from the front or back of the photovoltaic panel 2, or from other angled surfaces. Wind blowing perpendicular to the sides of the photovoltaic panel 2 has a very small contact area with the wind, thus not affecting the device. When wind blows from the front or back towards the photovoltaic panel 2, it pushes one of the wind plates 6 to move. The movement of the wind plate 6 moves the connecting rod 22, which in turn moves the piston plate 23. The two piston plates 23 do not move simultaneously. When one piston plate 23 moves, it increases the air pressure inside the gas casing 4, pushing the piston block 25 upwards. The upward movement of the piston block 25 moves the top rod 26 upwards, which in turn moves the push plate 21 upwards. The push plate 21 is positioned at the lower end of the photovoltaic panel 2. The contact between the photovoltaic panel 2 and the wind causes the photovoltaic panel 2 to rotate, bringing it to a horizontal position. The rotation of the photovoltaic panel 2 drives the rotating rod 10 to rotate, causing the return spring 15 to deform. When the wind stops, the rotating rod 10 returns to its original position under the action of the return spring 15. It should be noted that the clamp 3 holds the center of the photovoltaic panel 2, so that when the photovoltaic panel 2 is subjected to wind force, the wind force on the upper and lower positions is the same as the center horizontal line, thus canceling each other out. When the photovoltaic panel 2 is rotated, the push plate 21 can easily push the photovoltaic panel 2. When the wind blows, the wind force blows the wind plate 6, and under the action of the push plate 21, the photovoltaic panel 2 can be adjusted to a horizontal position, reducing the contact area between the photovoltaic panel 2 and the wind, thereby reducing the force on the photovoltaic panel 2, avoiding damage to the device due to excessive wind force, and improving the applicability of the device.

[0038] like Figure 6 As shown, both wind vanes 6 have arc-shaped grooves on their opposite sides, which can better receive wind force and make the wind force drive the wind vanes 6 more effectively.

[0039] like Figure 6 As shown, limit blocks 29 are fixedly connected to the front and rear positions inside the gas shell 4. The limit blocks 29 are used to restrict the movement of the piston plate 23 and prevent the piston plate 23 from moving to the lower end of the vertical block 7, so that the gas inside the gas shell 4 flows out from the upper end of the piston plate 23.

[0040] like Figure 9 As shown, a toothed plate 34 is fixedly connected to the lower end of the piston block 25. The piston block 25 and the toothed plate 34 move synchronously. A rod 33 is rotatably connected inside the vertical block 7. A gear 30 is fixedly connected to the rod wall of the rod 33. The rod 33 and the gear 30 rotate synchronously. The gear 30 meshes with the toothed plate 34. The rotation of the gear 30 causes the toothed plate 34 to move. Support blocks 31 are fixedly connected to both sides of the vertical block 7. A constant force spring 32 is fixedly connected inside the support block 31. The constant force spring 32 can provide a constant force, which is the prior art. The inside of the constant force spring 32 is fixedly connected to the rod wall of the rod 33.

[0041] In its initial state, the constant force spring 32 has a constant force, which gives the rod 33 a constant rotational force and the gear 30 a constant force. The gear 30 has a constant upward force, which is slightly smaller than the force of the push rod 26 and the push plate 21. This makes it easier for the air pressure inside the air shell 4 to push the push rod 26. The air pressure does not need to share the weight from the push rod 26 and the push plate 21, thus allowing the push plate 21 to better push the photovoltaic panel 2 to rotate, improving the wind resistance of the device.

[0042] like Figure 6 and Figure 8 As shown, a movable rod 28 is slidably connected inside the top rod 26. The movable rod 28 can move up and down relative to the top rod 26. The upper end of the movable rod 28 is rotatably connected to the lower end of the push plate 21. The push plate 21 can rotate relative to the upper end of the movable rod 28. A first spring 27 is fixedly connected to the lower end of the movable rod 28. The first spring 27 provides support for the movable rod 28. An L-shaped plate 35 is fixedly connected to both the front and rear positions of the upper end of the top rod 26. A rotating roller 36 is rotatably connected to the upper end of the L-shaped plate 35. The rotating roller 36 reduces the friction between the L-shaped plate 35 and the lower end of the push plate 21 when they come into contact.

[0043] When the top rod 26 moves upward, it drives the moving rod 28 to move. The moving rod 28 then drives the push plate 21 to move. Because the push plate 21 and the moving rod 28 rotate, the push plate 21 first comes into contact with the lower end of the photovoltaic panel 2. Then, the top rod 26 continues to move upward. At this time, the moving rod 28 cannot continue to move upward and moves downward relative to the top rod 26, compressing the first spring 27. The top rod 26 drives the two L-shaped plates 35 to move upward. Under the action of the two L-shaped plates 35, the push plate 21 rotates to a horizontal state. In this way, during operation, the push plate 21 first comes into contact with the photovoltaic panel 2, avoiding partial contact with the photovoltaic panel 2. Partial contact can easily damage the photovoltaic panel 2, thus further improving the device.

[0044] like Figure 3 and Figure 4 As shown, a rotating block 11 is fixedly connected to the rod wall of the rotating rod 10. The rotating rod 10 and the rotating block 11 rotate synchronously. An arc-shaped block 12 is slidably connected inside the rotating block 11. A second spring 14 is fixedly connected to one end of the arc-shaped block 12. The second spring 14 provides a certain support force to the arc-shaped block 12. The other end of the arc-shaped block 12 is partially embedded inside the support frame 1. A ball bearing 13 is movably provided at one end of the arc-shaped block 12, so that the friction between the arc-shaped block 12 and the inner wall of the support frame 1 is small when the arc-shaped block 12 moves.

[0045] One end of the arc-shaped block 12 is embedded inside the support frame 1. When the wind blows, the push plate 21 applies a pushing force to the photovoltaic panel 2. At this time, the rotating rod 10 has a rotational force. The rotating rod 10 is fixedly connected to the rotating block 11. The rotating block 11 has a rotational force to drive the arc-shaped block 12. However, because part of the arc-shaped block 12 is embedded inside the support frame 1, the arc-shaped block 12 moves relative to the inside of the support frame 1 only when the rotational force of the rotating block 11 is sufficient. The arc-shaped block 12 moves into the inside of the rotating block 11, and at the same time compresses the second spring 14. In this way, when the wind force is small, the photovoltaic panel 2 is kept in a stable state under the action of the arc-shaped block 12. Only when the wind force reaches a certain level will the photovoltaic panel 2 rotate, thus improving the stability of the photovoltaic panel 2.

[0046] like Figure 3 As shown, a liquid cylinder 8 is fixedly connected to one side of the circular block 9, and an orifice plate 16 is fixedly connected to the rod wall of the rotating rod 10. The liquid cylinder 8 is filled with hydraulic oil.

[0047] When the rotating rod 10 rotates, it drives the orifice plate 16 to rotate. When the orifice plate 16 rotates, it comes into contact with the hydraulic oil. The hydraulic oil provides resistance to the movement of the orifice plate 16. In this way, when the rotating rod 10 is subjected to a large force, the orifice plate 16 will prevent the rotating rod 10 from rotating rapidly. Thus, when the photovoltaic panel 2 rotates, whether it is turning to the horizontal or returning to the original position, it will rotate rapidly. In the event of a sudden strong wind, the photovoltaic panel 2 will not rotate suddenly. Only in the event of a continuous strong wind can the photovoltaic panel 2 be adjusted to be horizontal, which further improves the applicability of the device.

[0048] like Figure 5 As shown, the internal rotation of the liquid cylinder 8 is connected to a threaded rod 19, and the rod wall of the threaded rod 19 is threadedly connected to a toothed block 17. The internal opening of the rotating rod 10 is provided with a slot, and the internal opening of the slot is provided with a limiting groove 20. The limiting groove 20 matches the toothed block 17. The upper and lower positions of the inner wall of the liquid cylinder 8 are fixedly connected to a sliding rod 18, and the toothed block 17 can slide relative to the sliding rod 18. The rod wall of the sliding rod 18 is slidably connected to the internal opening of the toothed block 17.

[0049] When installing the photovoltaic panel 2, he rotates the threaded rod 19. At this time, the toothed block 17 moves under the action of the sliding rod 18. The toothed block 17 is embedded in the limiting groove 20, which limits the rotation of the rotating rod 10 so that the photovoltaic panel 2 is not allowed to rotate. This prevents the photovoltaic panel from rotating and affecting the installation.

[0050] Working Principle: When it's windy, it's important to note that the wind affecting the entire device only occurs when it blows from the front or back of the photovoltaic panel 2, or from other angled surfaces. Wind blowing perpendicular to the sides of the photovoltaic panel 2 has a very small contact area with the wind, thus having little impact on the device. When the wind blows from the front or back towards the photovoltaic panel 2, it pushes one of the wind plates 6 to move. The movement of the wind plate 6 moves the connecting rod 22, which in turn moves the piston plate 23. The two piston plates 23 do not move simultaneously. When one piston plate 23 moves, it increases the air pressure inside the gas casing 4, pushing the piston block 25 upwards. The upward movement of the piston block 25 moves the push rod 26 upwards, which in turn moves the push plate 21 upwards. The push plate 21 then moves in conjunction with the photovoltaic panel 2... The lower end of the photovoltaic panel 2 contacts the ground, causing it to rotate and become horizontal. The rotation of the photovoltaic panel 2 drives the rotating rod 10 to rotate, causing the return spring 15 to deform. When there is no wind, the rotating rod 10 returns to its original position under the action of the return spring 15. It should be noted that the clamp 3 holds the center of the photovoltaic panel 2, so that when the photovoltaic panel 2 is subjected to wind, the wind force at the upper and lower positions is the same as the center horizontal line, thus canceling each other out. When the photovoltaic panel 2 is rotated, the push plate 21 can easily push the photovoltaic panel 2. When the wind blows, the wind force blows the wind plate 6, and under the action of the push plate 21, the photovoltaic panel 2 can be adjusted to a horizontal state, reducing the contact area between the photovoltaic panel 2 and the wind, thereby reducing the force on the photovoltaic panel 2, avoiding damage to the device due to excessive wind force, and improving the applicability of the device.

[0051] Furthermore, the constant force spring 32 has a constant force in its initial state, which gives the rod 33 a constant rotational force, the gear 30 a constant force, and the gear 30 a constant upward force. This force is slightly smaller than the force of the push rod 26 and the push plate 21, which makes it easier for the air pressure inside the air shell 4 to push the push rod 26. The air pressure does not need to share the weight from the push rod 26 and the push plate 21, thereby making the push plate 21 better push the photovoltaic panel 2 to rotate and improving the wind resistance of the device.

[0052] Furthermore, when the top rod 26 moves upward, it drives the moving rod 28 to move. The moving rod 28 then drives the push plate 21 to move. Because the push plate 21 rotates with the moving rod 28, the push plate 21 first comes into contact with the lower end of the photovoltaic panel 2. Then, the top rod 26 continues to move upward. At this time, the moving rod 28 cannot continue to move upward and moves downward relative to the top rod 26, compressing the first spring 27. The top rod 26 drives the two L-shaped plates 35 to move upward. Under the action of the two L-shaped plates 35, the push plate 21 rotates to a horizontal state. In this way, during operation, the push plate 21 first comes into contact with the photovoltaic panel 2, and there will be no partial contact with the photovoltaic panel 2. Partial contact can easily damage the photovoltaic panel 2, thus further improving the device.

[0053] Furthermore, one end of the arc-shaped block 12 is embedded inside the support frame 1. When the wind blows, the push plate 21 applies a pushing force to the photovoltaic panel 2. At this time, the rotating rod 10 has a rotational force. The rotating rod 10 is fixedly connected to the rotating block 11. The rotating block 11 has a rotational force to drive the arc-shaped block 12. However, because part of the arc-shaped block 12 is embedded inside the support frame 1, the arc-shaped block 12 moves relative to the inside of the support frame 1 only when the rotational force of the rotating block 11 is sufficient. The arc-shaped block 12 moves into the inside of the rotating block 11 and compresses the second spring 14. In this way, when the wind force is small, the photovoltaic panel 2 is kept in a stable state under the action of the arc-shaped block 12. Only when the wind force reaches a certain level will the photovoltaic panel 2 rotate, thus improving the stability of the photovoltaic panel 2.

[0054] Furthermore, when the rotating rod 10 rotates, it drives the orifice plate 16 to rotate. When the orifice plate 16 rotates, it comes into contact with the hydraulic oil. The hydraulic oil provides resistance to the movement of the orifice plate 16. In this way, when the rotating rod 10 is subjected to a large force, the orifice plate 16 will not cause the rotating rod 10 to rotate rapidly. Thus, when the photovoltaic panel 2 rotates, whether it is turning to the horizontal or returning to the original position, it will not rotate rapidly. In the event of a sudden strong wind, the photovoltaic panel 2 will not rotate suddenly. Only in the event of a continuous strong wind can the photovoltaic panel 2 be adjusted to be horizontal, which further improves the applicability of the device.

[0055] Furthermore, when installing the photovoltaic panel 2, he rotates the threaded rod 19. At this time, the toothed block 17 moves under the action of the sliding rod 18. The toothed block 17 is embedded in the limiting groove 20, thereby limiting the rotating rod 10 so that it cannot rotate, thus preventing the photovoltaic panel 2 from being affected by rotation during installation.

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 its improved concepts, should be covered within the scope of protection of the present invention.
