Description

Technical Field

[0001] This invention relates to photovoltaic structures, and more particularly to a photovoltaic support structure. Background Technology

[0002] Currently, photovoltaic (PV) mounting systems generally suffer from poor coordination and ineffective fixing mechanisms, severely impacting the power generation efficiency and operational stability of PV power plants. Traditional PV mounting systems often use bolt locking and clip fixing to limit the angle of PV panels. This fixing method is not only cumbersome, requiring manual tightening and consuming significant labor costs, but also susceptible to damage from rain, dust, and temperature fluctuations, leading to bolt corrosion, clip wear, and loose connections. Under severe weather conditions such as strong winds, vibrations, and sandstorms, the angle of PV panels can easily shift, resulting in loose mounting systems and PV panel damage, directly reducing the light-gathering efficiency of the PV panels and affecting power generation revenue. Furthermore, the existing PV mounting systems have independent angle adjustment and fixing mechanisms. The adjustment mechanism is responsible for adjusting the PV panel angle, while the fixing mechanism is responsible for locking the angle. The lack of an effective linkage mechanism requires an additional independent power source to drive the fixing mechanism, increasing energy consumption and complicating the overall structure of the mounting system. This not only increases equipment manufacturing costs but also increases the difficulty and cost of subsequent operation and maintenance, hindering the efficient operation of large-scale PV power plants.

[0003] Furthermore, traditional support structures are poorly designed and struggle to adapt to the angle adjustment requirements of photovoltaic panels. They either employ rigid fixing structures, hindering panel angle adjustment, or use flexible supports that fail to provide stable support, leading to swaying. Simultaneously, most support systems lack targeted protective components, leaving the core components of the angle adjustment and fixing mechanisms directly exposed to the outdoors, making them susceptible to environmental corrosion. This results in component aging, frequent failures, and a shortened overall lifespan of the support system, failing to meet the practical needs of long-term, efficient, and stable operation of large-scale photovoltaic power plants. Therefore, a photovoltaic support structure design that can solve these problems is urgently needed. Summary of the Invention

[0004] Purpose of the Invention: The purpose of this invention is to automatically operate the fixing mechanism using the existing angle adjustment power, achieving automated control of fixing and unlocking without the need for an additional power source. This simplifies the overall structure, reduces energy consumption and maintenance costs, and adapts to the automatic angle adjustment and reset process of photovoltaic panels, improving the automation level of the support system while balancing structural innovation and practicality. Another purpose of this invention is to eliminate the need for additional complex locking structures. By precisely limiting the range of motion of the support structure through air pressure difference, the angle of the photovoltaic panel is stably locked, preventing angle deviation caused by external forces and ensuring that the photovoltaic panel is always at the optimal light-receiving angle, thereby improving the stability and ease of operation of the support system.

[0005] Technical solution: A photovoltaic support structure includes a base. Perforated support rods are symmetrically fixedly connected to the upper surface of the base. Rotary columns are rotatably connected inside each of the perforated support rods. A photovoltaic panel is fixedly connected to the opposite sides of each rotary column. A transmission wheel is fixedly connected to the opposite ends of each rotary column. Rotary holes are formed on the lower outer walls of each of the perforated support rods. Horizontal columns are rotatably connected inside each of the two rotary holes. A transmission wheel is fixedly connected to the end of each horizontal column. A transmission belt is wound around the outer walls of adjacent transmission wheels.

[0006] Furthermore, a crossbar is symmetrically fixedly connected to the upper surface of the base, and a support block is symmetrically fixedly connected to the upper surface of the crossbar behind it. A rotating rod is fixedly connected to the opposite side of the support block. A transmission gear is rotatably connected to the outer wall of the rotating rod. A short gear is fixedly connected to the outer wall of the crossbar. The transmission gear and the short gear are meshed together. A fixing ring is fixedly connected to the left side of the outer wall of the rotating rod. A fixing rod is fixedly connected to the outer wall of the fixing ring. A turntable is rotatably connected to the front surface of the fixing rod.

[0007] Furthermore, a ring of toothed blocks is arranged sequentially on the rear surface of the turntable, and a ring of toothed grooves is opened at the left end of the transmission toothed column. The toothed blocks are meshed with the toothed grooves. Vertical rods are symmetrically fixedly connected to the upper surface of the front crossbar, and a motor is fixedly connected to the right side of the right vertical rod. A linkage rod is fixedly connected to the output end of the motor.

[0008] Furthermore, the linkage rod passes through the right vertical rod and is rotatably connected to it. A limit ring is symmetrically fixedly connected to the outer wall of the linkage rod, and a wedge gear is rotatably connected to the outer wall of the limit ring. A front groove is formed on the front surface of the turntable, and both wedge gears are meshed with the front groove. A limit rod is symmetrically fixedly connected to the outer wall of the linkage rod.

[0009] Furthermore, the outer wall of the linkage rod is slidably connected to a sliding sleeve, the inner wall of the sliding sleeve is provided with multiple limiting grooves, the limiting rod is slidably connected to the inside of the limiting groove, the outer wall of the sliding sleeve is rotatably connected to a perforated plate, and the opposite ends of the sliding sleeve are fixedly connected to a slot.

[0010] Furthermore, each of the opposite sides of the wedge gear is fixedly connected to a sleeve, and the slot can engage with the sleeve. A timing servo is fixedly connected to the front surface of the front crossbar, and a telescopic cavity is fixedly connected to the output end of the timing servo. A sliding rod is slidably connected inside the telescopic cavity, and the sliding rod is fixedly connected to the front surface of the perforated plate.

[0011] Furthermore, the upper surface of the base is symmetrically fixedly connected with sliding cavities, each sliding cavity has a piston block slidably connected inside, each piston block has a supporting vertical plate slidably connected inside, and each supporting vertical plate is rotatably connected to the outer wall of the photovoltaic panel.

[0012] Furthermore, two air leakage holes are provided on the outer wall of the front sliding cavity. A sliding column is slidably connected to the front surface of the front sliding cavity. An upper air-blocking plate is fixedly connected to the opposite side of the sliding column, and a lower air-blocking plate is fixedly connected to the opposite side of the sliding column. A front rod is fixedly connected to the front surface of the telescopic cavity. The front section of the front rod extends through to the front surface of the base. A rotating block is fixedly connected to the front surface of the front rod. Openings are provided on both sides of the rotating block. A long rod is rotatably connected inside each opening. The ends of the long rods are rotatably connected to the outer wall of the sliding column through a rotating component.

[0013] Furthermore, a protective shell is fixedly connected to the right side of the upper surface of the base.

[0014] Beneficial Effects: This design breaks through the limitations of traditional photovoltaic (PV) brackets where the adjustment and fixing mechanisms are independent and lack coordination. Through the linkage design of a timed servo motor, telescopic cavity, rotating block, long rod, and sliding column, it organically combines angle adjustment power with angle limiting operation, forming a complete automated collaborative system—a groundbreaking innovation in structural design. Its novelty lies in utilizing the preset operating rules of the timed servo motor to drive the front rod, rotating block, and long rod in a coordinated manner, thereby controlling the movement of the sliding column and air-blocking plate to achieve automatic sealing and unlocking of leak holes. No additional power source is needed to drive the angle limiting mechanism, reducing energy consumption and simplifying the overall structural layout. This linkage design allows the PV panel to be immediately and securely locked after angle adjustment, preventing angle deviation during the adjustment process. It also automatically unlocks during nighttime reset without manual intervention, significantly improving the automation level of the PV bracket. This demonstrates the innovation of the structural design, effectively reduces operation and maintenance costs, and meets the high-efficiency operation requirements of large-scale PV power plants.

[0015] By selectively moving the air-blocking plate to seal leaks and using air pressure difference to limit the sliding range of the piston block, the angle of the photovoltaic panel is stably limited by the supporting vertical plate. This eliminates the need for complex additional locking components, resulting in a simple and innovative structure. This design effectively solves the problem of photovoltaic panel angle shift caused by external forces (such as strong winds and vibrations) in traditional fixing methods, ensuring the photovoltaic panel always maintains the optimal light-receiving angle. It also avoids the wear and loosening risks associated with bolt locking, and eliminates the need for manual locking, adapting to the automatic angle adjustment process of the photovoltaic panel. This significantly improves the stability and convenience of the support system, balancing structural innovation with practical performance.

[0016] This design provides auxiliary support for the photovoltaic panels without hindering their angle adjustment, overcoming the limitations of traditional support structures that are either fixed or inconvenient to adjust, thus forming a support system that can adapt to changes in angle. Simultaneously, the corresponding design of the double air-sealing plates and double air-leaking holes allows for precise sealing of air-leaking holes at different locations based on the photovoltaic panel's adjustment direction, achieving directional restriction of the piston block's sliding direction. This adapts to the fixing requirements of photovoltaic panels at different angles, resulting in a flexible and innovative structural design. Furthermore, the addition of a protective shell specifically protects the core components of the angle-limiting mechanism from external factors such as rain and dust, extending the component's lifespan. The overall structure is compatible with the existing angle adjustment mechanism, requiring no major modifications to the main support structure, thus balancing structural innovation and compatibility.

Detailed Implementation

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figures 1-8As shown, a photovoltaic support structure is provided, including a base 1. Perforated support rods 2 are symmetrically fixedly connected to the upper surface of the base 1. Rotary columns 3 are rotatably connected inside each of the perforated support rods 2. A photovoltaic panel 4 is fixedly connected to opposite sides of each of the rotating columns 3. A first transmission wheel 5 is fixedly connected to the opposite ends of each rotating column 3. Rotating holes 6 are opened below the outer walls of each of the perforated support rods 2. Horizontal columns 7 are rotatably connected inside each of the two rotating holes 6. A second transmission wheel 8 is fixedly connected to the end of each horizontal column 7. A transmission belt 9 is wound around the outer walls of adjacent first transmission wheels 5 and second transmission wheels 8. Horizontal bars 10 are symmetrically fixedly connected to the upper surface of the base 1. The rear horizontal bar 10... A support block 11 is symmetrically fixedly connected to the upper surface of the support block 11. A rotating rod 12 is fixedly connected to the opposite side of the support block 11. A transmission gear 13 is rotatably connected to the outer wall of the rotating rod 12. A short gear 14 is fixedly connected to the outer wall of the horizontal column 7. The transmission gear 13 and the short gear 14 are meshed together. A fixing ring 15 is fixedly connected to the left side of the outer wall of the rotating rod 12. A fixing rod 16 is fixedly connected to the outer wall of the fixing ring 15. A turntable 17 is rotatably connected to the front surface of the fixing rod 16. A ring of toothed blocks 18 is arranged sequentially on the rear surface of the turntable 17. A ring of toothed grooves 19 is opened at the left end of the transmission gear 13. The toothed blocks 18 and the short gear 19 are meshed together. The gear groove 19 is meshed and connected. Vertical rods 20 are symmetrically fixedly connected to the upper surface of the front horizontal bar 10. A motor 21 is fixedly connected to the right side of the right vertical bar 20. A linkage rod 44 is fixedly connected to the output end of the motor 21. The linkage rod 44 passes through the right vertical bar 20 and is rotatably connected to it. A limit ring 22 is symmetrically fixedly connected to the outer wall of the linkage rod 44. A wedge gear 23 is rotatably connected to the outer wall of the limit ring 22. A front groove 24 is formed on the front surface of the turntable 17. Both wedge gears 23 mesh with the front groove 24. A limit rod 25 is symmetrically fixedly connected to the outer wall of the linkage rod 44. The wall is slidably connected to a sliding sleeve 26. The inner side wall of the sliding sleeve 26 is provided with multiple limiting grooves 27. The limiting rods 25 are all slidably connected to the inside of the limiting grooves 27. The outer side wall of the sliding sleeve 26 is rotatably connected to a perforated plate 28. The opposite ends of the sliding sleeve 26 are fixedly connected to slots 29. The opposite sides of the wedge gear 23 are fixedly connected to sleeves 30. The slots 29 can engage with the sleeves 30. The front surface of the front crossbar 10 is fixedly connected to a timing servo motor 31. The output end of the timing servo motor 31 is fixedly connected to a telescopic cavity 32. The inside of the telescopic cavity 32 is slidably connected to a sliding rod 33. The sliding rod 33 is fixedly connected to the front surface of the perforated plate 28.

[0029] The base 1 provides stable support for the entire device. The perforated support rods 2 symmetrically fixed above it provide a base for the rotating column 3 to be mounted. The photovoltaic panels 4 fixed on opposite sides of the rotating column 3 are used to receive solar energy. During operation, the timer servo motor 31 fixed on the front surface of the front crossbar 10 is activated. Its output end drives the telescopic cavity 32 to move, causing the sliding rod 33 slidably connected inside the telescopic cavity 32 to extend and retract. The sliding rod 33 drives the perforated plate 28 fixedly connected to it to move. The perforated plate 28 drives the sliding sleeve 26 rotatably connected to it to slide on the linkage rod 44. The sliding sleeve 26 is connected to the limiting rod 2 fixed on the linkage rod 44 through the limiting groove 27 on the inner side wall. 5. To ensure stable sliding, when the groove 29 fixed at the opposite end of the sliding sleeve 26 engages with the sleeve 30 fixed on the opposite side of the wedge gear 23, the motor 21 fixed on the right side of the right vertical rod 20 starts, and its output end drives the linkage rod 44 to rotate. The linkage rod 44 passes through the right vertical rod 20 and is rotatably connected to it. The limiting ring 22 symmetrically fixed on its outer wall limits the wedge gear 23, so that the wedge gear 23 rotates stably. The rotating wedge gear 23 meshes with a front groove 24 opened on the front surface of the turntable 17, driving the turntable 17 to rotate around the fixed rod 16. The fixed rod 16 is fixed to the fixing ring on the left side of the outer wall of the rotating rod 12. On 15, the rotating rod 12 is jointly fixed by the support blocks 11 symmetrically fixed on the rear crossbar 10 on opposite sides. A ring of toothed blocks 18 arranged sequentially on the rear surface of the turntable 17 meshes with a ring of toothed grooves 19 opened at the left end of the transmission toothed column 13, driving the transmission toothed column 13 to rotate around the rotating rod 12. The transmission toothed column 13 meshes with the short toothed column 14 fixed on the outer wall of the crossbar 7, thereby driving the crossbar 7 to rotate in the rotating hole 6 opened below the outer wall of the perforated support rod 2. The transmission wheel 2 8 fixed at the end of the crossbar 7 drives the transmission wheel 1 5 fixed at the opposite end of the rotating column 3 to rotate through the transmission belt 9 wrapped around the outer wall. The rotating column 3 rotates inside the perforated support rod 2, ultimately driving the rotating rod 12 to rotate. The photovoltaic panel 4 on the opposite side of column 3 adjusts its angle, and the timer servo 31 works according to the preset time pattern. It does not need to rotate quickly and only consumes a small amount of electricity. During the day, it continuously drives the linkage of various components to keep the photovoltaic panel 4 at the angle with the sun's surface with the most contact, ensuring that the lighting effect is always in the best state. At night, it drives the components to reset to prepare for the next day's lighting. Throughout the process, the vertical rods 20 symmetrically fixed on the front horizontal bar 10 provide support for the motor 21 and linkage rod 44, while the rear horizontal bar 10 provides a fixed foundation for the support block 11, further ensuring the stable operation of the entire bracket structure to achieve the above functions.

[0030] In this embodiment, the upper surface of the base 1 is symmetrically fixedly connected with sliding cavities 34, and piston blocks 35 are slidably connected inside the sliding cavities 34. Supporting vertical plates 36 are slidably connected inside the piston blocks 35. The supporting vertical plates 36 are rotatably connected to the outer side wall of the photovoltaic panel 4. Two air leakage holes 37 are opened on the outer side wall of the front sliding cavity 34. A sliding column 38 is slidably connected to the front surface of the front sliding cavity 34. An upper air blocking plate 39 is fixedly connected to the opposite side of the sliding column 38. A lower air blocking plate 46 is fixedly connected to the opposite side of the sliding column 38. A front rod 40 is fixedly connected to the front surface of the telescopic cavity 32. The front section of the front rod 40 extends through to the front surface of the base 1. A rotating block 41 is fixedly connected to the front surface of the front rod 40. An opening 42 is opened on both sides of the rotating block 41. A long rod 43 is rotatably connected inside the opening 42. The end of the long rod 43 is rotatably connected to the outer side wall of the sliding column 38 through a rotating component. A protective shell 45 is fixedly connected to the right side of the upper surface of the base 1.

[0031] Piston blocks 35 are slidably connected inside the symmetrically fixed sliding cavities 34 on the upper surface of the base 1. The supporting vertical plates 36 slidably connected inside the piston blocks 35 are rotatably connected to the outer wall of the photovoltaic panel 4. When it is necessary to adjust and fix the angle of the photovoltaic panel 4, the rotating block 41 fixedly connected to the front rod 40 on the front surface of the base 1 is rotated. The rear end of the front rod 40 is fixedly connected to the front surface of the telescopic cavity 32 and extends through to the front surface of the base 1. The long rods 43 rotatably connected inside the openings 42 on both sides of the rotating block 41 will drive the sliding column 38 connected to its end through the rotating part to slide on the front surface of the front sliding cavity 34 as the rotating block 41 rotates. The upper air-blocking plate 39 fixed on the opposite side of the sliding column 38 and the lower air-blocking plate 46 fixed on the opposite side will move with the sliding column 38, thereby selectively sealing the two air leakage holes 37 opened on the outer wall of the front sliding cavity 34. Among them, the upper air-blocking plate 39 is fixed on the opposite side of the sliding column 38 and the lower air-blocking plate 46 fixed on the opposite side of the sliding column 38 will move with the sliding column 38, thereby selectively sealing the two air leakage holes 37 opened on the outer wall of the front sliding cavity 34. When the upper vent 37 is blocked, the upper air pressure in the sliding cavity 34 cannot be released, causing the piston block 35 to slide downwards instead of upwards. When the lower vent 46 blocks the lower vent 37, the lower air pressure in the sliding cavity 34 cannot be released, causing the piston block 35 to slide upwards instead of downwards. By blocking the vents 37 at different positions, the sliding range of the piston block 35 in the sliding cavity 34 can be precisely limited. After the position of the piston block 35 is fixed, the support vertical plate 36 slidably connected inside it cannot move freely, thereby limiting the rotation angle of the photovoltaic panel 4 rotatably connected to the support vertical plate 36, preventing external forces such as strong winds from causing the photovoltaic panel 4 to reset. At the same time, the protective shell 45 fixedly connected to the right side of the upper surface of the base 1 protects the relevant components and ensures the stable operation of the entire angle limiting mechanism.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
