Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a single-axis photovoltaic tracking support and photovoltaic system with self-correcting capability. Background Technology

[0002] Photovoltaic tracking systems are core equipment for improving solar energy utilization. By adjusting the angle of sunlight received by photovoltaic modules in real time, they can significantly improve the power generation efficiency per unit area. They have become the mainstream supporting device for ground-mounted photovoltaic power stations, and their operational stability directly affects the overall power generation revenue of the power station.

[0003] Ground-mounted photovoltaic power stations are often built in complex terrain areas such as mountains and tidal flats, where the foundations are prone to uneven settlement. At the same time, the equipment is subject to natural wind loads and vibrations over a long period of time, which can easily lead to structural displacement, stress concentration and other problems. Therefore, it is necessary to provide a supporting structure with adaptive adjustment capabilities to ensure reliable operation.

[0004] Existing photovoltaic support structures are unable to effectively counteract structural displacement and additional stress caused by uneven settlement when dealing with foundation settlement. At the same time, they have poor buffering and energy absorption effects under instantaneous impacts such as wind loads and mechanical vibrations, making it difficult to maintain stable transmission coordination and operating posture. They cannot meet the actual usage requirements of long-term reliable operation and structural posture correction of photovoltaic tracking systems. Summary of the Invention

[0005] This invention provides a single-axis photovoltaic tracking bracket and photovoltaic system with self-correcting capability to solve the technical problems of existing photovoltaic bracket support structures, which are unable to effectively offset the structural displacement and additional stress caused by uneven settlement when dealing with foundation settlement. At the same time, they have poor buffering and energy absorption effects under instantaneous impacts such as wind loads and mechanical vibrations, making it difficult to maintain stable transmission coordination and operating posture, and thus failing to meet the actual use requirements of long-term reliable operation and structural posture correction of photovoltaic tracking systems.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] On one hand, a self-correcting single-axis photovoltaic tracking bracket includes a base, the base being connected to a rotating shaft via an adaptive component, the adaptive component including a pole body mounted on the base, a movable component that can move up and down installed inside the pole body, a buffer component installed on the top of the movable component, a rotating shaft installed on the top of the buffer component, the rotating shaft being driven to rotate by a drive component, and a support component including a spring, the two ends of the spring being connected to the mounting rod and the support rod respectively.

[0008] Optionally, the adaptive component includes an installation cavity opened within the main body of the pole, a lead screw rotatably mounted between the installation cavities, a movable component slidably disposed within the installation cavity located at the highest point, a top rod fixedly mounted at the end of the buffer component away from the movable component, a connecting bearing for connecting the rotating shaft fixedly mounted on the top rod, and the buffer component being a disc spring, wherein multiple sets of disc springs are arranged in combination.

[0009] Optionally, a mounting box is fixedly installed in the mounting cavity located at the lower point, a worm gear is rotatably installed in the mounting box, and a turbine cooperating with the worm gear is fixedly installed at the end of the lead screw away from the buffer.

[0010] Optionally, the rotating shaft is configured in multiple segments, and the multiple segments of the rotating shaft are connected by a universal joint.

[0011] Optionally, the main body of the pole has a movable cavity, and a protective plate is slidably installed in the movable cavity. The protective plate is used to seal the installation cavity at the lowest point.

[0012] Optionally, the support assembly includes a mounting rod, the spring is fixedly mounted inside the mounting rod, a support rod is fixedly mounted on the spring, the support rod is slidably mounted inside the mounting rod, and a support plate is fixedly mounted on the support rod.

[0013] Optionally, the drive assembly includes a mounting bracket fixedly mounted on a support rod, a motor fixedly mounted on the mounting bracket, a gear fixedly mounted on the output shaft of the motor, a toothed plate that mates with the gear slidably mounted inside the support plate, and a toothed groove that meshes with the toothed plate on the rotating shaft.

[0014] Optionally, a rotating frame is rotatably mounted on the outer wall of the motor, a wind baffle is fixedly mounted on the rotating frame, a stop plate is fixedly mounted on the mounting frame, an elastic element is fixedly mounted on the stop plate, the end of the elastic element away from the stop plate is fixedly connected to the rotating frame, and a reset controller is fixedly mounted on the stop plate.

[0015] Optionally, the rotating shaft is provided with a mounting purlin, and a mounting frame is fixedly mounted on the mounting purlin. A photovoltaic panel is connected to the mounting frame through a fine-tuning component. The fine-tuning component includes a connecting frame rotatably mounted in the mounting frame. The photovoltaic panel is fixedly mounted on the connecting frame. A telescopic rod is fixedly mounted on the mounting frame. A protrusion is fixedly mounted on the photovoltaic panel.

[0016] On the other hand, a photovoltaic system includes the aforementioned self-correcting single-axis photovoltaic tracking bracket, on which a photovoltaic panel is mounted.

[0017] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0018] In the above scheme, the base serves as a stable foundation supporting the superstructure. The main body of the adaptive component's upright is fixed to the base, and the movable parts within the upright can move precisely vertically. The buffer at the top of the movable parts directly supports the rotating shaft, which rotates and tracks under the power of the drive component. When uneven settlement occurs in the foundation, the main body of the upright moves vertically synchronously with the base, and the movable parts move in tandem. The buffer utilizes elastic deformation to offset the vertical displacement and additional stress caused by the settlement in real time, preventing stress transmission to the rotating shaft. When encountering instantaneous impacts such as wind loads or mechanical vibrations, the buffer rapidly undergoes elastic deformation, efficiently absorbing impact energy and weakening the vibration's disturbance to the rotating shaft and the overall structure.

[0019] The springs at both ends of the support assembly are connected to the mounting rod and the support rod, respectively, to continuously provide elastic support force, ensuring that the drive assembly and the rotating shaft always maintain a stable transmission connection and preventing the drive from becoming loose or misaligned.

[0035] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides a self-correcting single-axis photovoltaic tracking bracket, including a base 1. The base 1 is connected to a rotating shaft 11 via an adaptive component 2. The adaptive component 2 includes a pole body 21 mounted on the base 1. A movable component 27 capable of moving up and down is installed inside the pole body 21. A buffer component 28 is installed on the top of the movable component 27. A rotating shaft is installed on the top of the buffer component 28. The rotating shaft 11 is driven to rotate by a drive component 3. The support component includes a spring 44, and the two ends of the spring 44 are respectively connected to the mounting rod 41 and the support rod 42.

[0038] In this embodiment, the base 1 serves as a stable foundation to support the upper structure. The main body 21 of the adaptive component 2 is fixed to the base 1. The movable part 27 inside the main body 21 can move precisely vertically. The buffer part 28 at the top of the movable part 27 directly supports the rotating shaft 11. The rotating shaft 11 achieves rotational tracking under the power of the drive component 3.

[0039] When uneven settlement occurs in the foundation, the main body 21 of the upright pole moves vertically synchronously with the base 1, and the moving part 27 moves in tandem. The buffer 28 uses elastic deformation to offset the vertical displacement and additional stress caused by the settlement in real time, blocking the transmission of stress to the rotating shaft 11. When encountering instantaneous impacts such as wind loads and mechanical vibrations, the buffer 28 quickly undergoes elastic deformation, efficiently absorbing the impact energy and weakening the disturbance of vibration to the rotating shaft 11 and the overall structure. In this embodiment, the spring 44 of the support component 4 is connected to the mounting rod 41 and the support rod 42 at both ends, providing continuous elastic support force to ensure that the drive component 3 and the rotating shaft 11 always maintain a stable transmission connection and avoid drive loosening and misalignment.

[0040] like Figure 6 As shown, the adaptive component 2 includes an installation cavity 22 within the main body 21 of the upright. A lead screw 23 is rotatably mounted between the installation cavities 22. A movable component 27 is slidably disposed within the installation cavity 22 at the highest point. A top rod 29 is fixedly mounted on the end of the buffer component 28 away from the movable component 27. A connecting bearing 210 for connecting the rotating shaft 11 is fixedly mounted on the top rod 29. The buffer component 28 is a disc spring, and multiple disc springs are arranged in combination. The lead screw 23 is rotatably assembled within the installation cavity 22. The movable component 27 in the installation cavity 22 at the highest point forms a threaded pair with the lead screw 23, allowing for precise vertical displacement as the lead screw 23 rotates. The top of the movable component 27 is fixedly connected to the buffer component 28, which consists of multiple disc springs. The top of the disc spring group is connected to the connecting bearing 210 via the top rod 29. The bearing is directly fitted onto the outer circumference of the rotating shaft 11, achieving uniform transmission of buffering force to the rotating shaft 11. When foundation settlement is detected, causing a height deviation of the shaft 11, the disc springs utilize their elastic properties to adaptively offset the vertical displacement, structural deformation, and additional stress caused by the settlement in real time. Then, maintenance personnel can rotate the lead screw 23, which drives the moving part 27 to rise and fall through the threaded transmission, thereby pushing the disc spring assembly, the top rod 29, and the connecting bearing 210 to move vertically in sync, accurately compensating for the height difference of the shaft 11 support. The combination of multiple disc springs utilizes the characteristics of small stroke and large load, with elastic deformation offsetting the height difference stress during settlement and rapid energy absorption and vibration reduction during wind vibration. The connecting bearing 210 ensures that there is no additional frictional resistance when the shaft 11 rotates, maintaining smooth rotation.

[0041] like Figure 7As shown, a mounting box 24 is fixedly installed in the mounting cavity 22 at the lowest point. A worm gear 26 is rotatably installed in the mounting box 24. A worm wheel 25 that cooperates with the worm gear 26 is fixedly installed at the end of the lead screw 23 away from the buffer member 28. The rotation of the worm gear 26 drives the worm wheel 25 to rotate synchronously, and the worm wheel 25 then drives the lead screw 23 to rotate, thereby driving the moving part 27 to complete the lifting action. The worm gear 26 has a reverse self-locking characteristic. After adjustment, external loads cannot drive the worm gear 26 to rotate in the reverse direction, which can ensure that the adjusted position remains fixed. Combined with the self-locking characteristic of the lead screw 23 itself, a double locking is formed, which will not loosen, fall back or shift, so that the support height after settlement correction is stable for a long time, improving the reliability and safety of the support operation.

[0042] like Figure 1 , 2 As shown in Figure 5, the rotating shaft 11 is configured in multiple segments, which are connected by universal joints 15. The rotating shaft 11 adopts a multi-segment structure design, with adjacent segments connected and torque transmitted via universal joints 15. When uneven settlement of the foundation causes height differences, axial misalignment, or angular deviations in the segments of the rotating shaft 11, the universal joints 15 can adaptively compensate in the axial, radial, and angular directions, allowing for a certain angle and radial displacement between adjacent segments without affecting the stable transmission of rotational torque. During the tracking drive process, the multiple segments of the rotating shaft 11 can maintain synchronous rotation, avoiding additional bending moments, shear forces, and torsional stresses caused by misalignment or non-alignment, preventing deformation, jamming, or breakage of the rotating shaft 11. The universal joints 15 can automatically compensate for installation errors, operational deformation, and settlement deviations, ensuring good coaxiality and motion consistency of the entire long shaft, achieving synchronous tracking of the entire row of supports, and correcting the long shaft's deviation. The universal joint 15 in this embodiment adopts existing technology, and will not be described in detail here.

[0043] like Figure 6 As shown, the main body 21 of the pole has a movable cavity 221, and a protective plate 222 is installed inside the movable cavity 221. The protective plate 222 is used to seal the installation cavity 22 at the lowest point. The protective plate 222 can completely seal the opening area of ​​the installation cavity 22 at the lowest point, preventing rainwater, dust, mud, insects, etc. from the outdoor environment from entering the installation cavity 22, and avoiding corrosion, jamming, or wear of precision transmission components such as worm gear, worm 26, and lead screw 23.

[0044] like Figure 4As shown, the support assembly 4 includes a mounting rod 41, a spring 44 fixedly installed inside the mounting rod 41, a support rod 42 fixedly installed on the spring 44, the support rod 42 slidably installed inside the mounting rod 41, and a support plate 43 fixedly installed on the support rod 42. The spring 44 is fixedly installed inside the mounting rod 41, and is in a pre-compressed state, continuously applying an elastic pushing force upwards. Under the pushing force of the spring 44, the support rod 42 can float along the axis of the mounting rod 41. The support plate 43 is fixed to the upper end of the support rod 42, and the support rod 42 and support plate 43 directly support the upper drive assembly 3. When the foundation settles or the structure undergoes slight deformation, the spring 44 adaptively compensates for the height difference through extension and retraction, pushing the support rod 42 and support plate 43 to maintain a constant support height, ensuring that the drive assembly 3 and the rotating shaft 11 always maintain a stable contact state, avoiding drive failure, tooth dislodgement, or shaking due to height deviation, and ensuring continuous and stable tracking drive. The spring 44, support rod 42, and support plate 43 work together to float and support, adaptively compensating for height deviations and ensuring stable drive contact.

[0045] like Figure 3 As shown, the drive assembly 3 includes a mounting bracket 31 fixedly mounted on a support rod 42. A motor 33 is fixedly mounted on the mounting bracket 31, and a gear 32 is fixedly mounted on the output shaft of the motor 33. A toothed plate 34 that meshes with the gear 32 is slidably mounted inside the support plate 43. A toothed groove 35 that meshes with the toothed plate 34 is provided on the rotating shaft 11. The motor 33 is fixed on the mounting bracket 31, and the output shaft of the motor 33 drives the gear 32 to rotate. The gear 32 meshes with the toothed plate 34, converting the rotational motion into the linear motion of the toothed plate 34. The toothed plate 34 is slidably assembled inside the support plate 43, and the support plate 43 provides guidance and limitation for the toothed plate 34. The toothed plate 34 meshes with the toothed groove 35 on the rotating shaft 11. When the toothed plate 34 moves linearly, it drives the rotating shaft 11 to rotate around the axis through the toothed groove 35, thereby realizing the adjustment of the solar tracking angle. The elastic support of the support component 4 ensures that the toothed plate 34 and the toothed groove 35 are always tightly meshed, and there will be no tooth loss or skipping due to settlement, vibration or load changes, ensuring that the driving force is transmitted smoothly and the rotation angle of the rotating shaft 11 is precisely controllable.

[0046] For example Figure 3As shown, a rotating frame 36 is rotatably mounted on the outer wall of the motor 33. A wind baffle 37 is fixedly mounted on the rotating frame 36. A stop plate 310 is fixedly mounted on the mounting frame 31. An elastic element 38 is fixedly mounted on the stop plate 310. The end of the elastic element 38 away from the stop plate 310 is fixedly connected to the rotating frame 36. A reset controller 39 is fixedly mounted on the stop plate 310. The rotating frame 36 is rotatably mounted on the outer wall of the motor 33, and the wind baffle 37 is fixed on the rotating frame 36 to form a wind load sensing structure. The stop plate 310 is fixed on the mounting frame 31. An elastic element 38 is provided between the stop plate 310 and the rotating frame 36. The elastic element 38 is in a pre-compressed state to provide a reset force for the rotating frame 36. The reset controller 39 is mounted on the stop plate 310 to detect the deflection position of the rotating frame 36 and output a control signal. When strong winds act on the photovoltaic modules, the wind pressure pushes the wind deflector 37, causing the rotating frame 36 to deflect around the outer wall of the motor 33. During the deflection process, the elastic element 38 is compressed, and the deformation of the elastic element 38 absorbs the impact energy of the wind load. When the deflection angle reaches the threshold, the rotating frame 36 triggers the reset controller 39. The controller sends a signal to control the motor 33 to perform a wind-avoiding rotation action, realizing automatic wind avoidance and automatic reset in strong winds, thus improving wind resistance safety.

[0047] like Figure 9 As shown, a mounting purlin 12 is provided on the rotating shaft 11, and a mounting frame 13 is fixedly mounted on the mounting purlin 12. A photovoltaic panel 14 is connected to the mounting frame 13 through a fine-tuning component 5. The fine-tuning component 5 includes a connecting frame 51 rotatably mounted inside the mounting frame 13. The photovoltaic panel 14 is fixedly mounted on the connecting frame 51. A telescopic rod 52 is rotatably mounted on the mounting frame 13. A protrusion 53 is fixedly mounted on the photovoltaic panel 14, and the protrusion 53 is rotatably connected to the output shaft of the telescopic rod 52. The mounting frame 13 provides a mounting carrier for the photovoltaic panel 14. The photovoltaic panel 14 is fixed on the connecting frame 51 and can rotate slightly with the connecting frame 51. When the telescopic rod 52 moves in extension and retraction, the output end pushes and pulls the protrusion 53, which drives the photovoltaic panel 14 to make a pitch angle fine adjustment with the connecting frame 51 as the fulcrum. Based on the overall tracking of the rotating shaft 11, the light receiving angle is further optimized, and the component installation deviation, terrain tilt angle and tracking residual error are compensated, so that the photovoltaic panel 14 always maintains the best light receiving posture. The entire fine adjustment mechanism is flexible and responsive, and can realize high-precision angle correction and light tracking optimization at the component level.

[0048] Example 2

[0049] like Figure 1 As shown, this embodiment discloses a photovoltaic system, including the above-mentioned correctable single-axis photovoltaic tracking bracket, on which a photovoltaic panel 14 is mounted.

[0050] The working process of the self-correcting single-axis photovoltaic tracking bracket and photovoltaic system provided by this invention is as follows:

[0051] The base 1 serves as the installation foundation for the entire single-axis photovoltaic tracking bracket, providing fixation and load-bearing support for all structures above it. The base 1 is connected to the rotating shaft 11 through the adaptive component 2. The adaptive component 2 has a built-in buffer 28. When uneven settlement occurs in the foundation on which the bracket is located, the buffer 28 uses its own elastic properties to adaptively offset the vertical displacement, structural deformation and additional stress caused by the settlement in real time, avoiding stress concentration to be transmitted to the rotating shaft 11 and causing damage. At the same time, under the action of instantaneous loads such as wind load and mechanical vibration, the buffer 28 can quickly undergo elastic deformation to absorb impact energy and reduce the impact of vibration on the rotating shaft 11 and the overall structure.

[0052] The support component 4 is arranged directly below the center of the rotating shaft 11, providing stable support and positioning constraints for the drive component 3. This ensures that the drive component 3 maintains a stable fit with the rotating shaft 11 during operation, preventing loosening, misalignment, or disengagement during the drive process. It also ensures that the driving force can be smoothly and evenly transmitted to the rotating shaft 11, guaranteeing the continuous and reliable rotation of the rotating shaft 11 and achieving stable execution of the tracking action.

[0053] It achieves adaptive settlement compensation, impact load absorption and driving stability support, and completes foundation-level passive correction.

[0054] When the lead screw 23 rotates, the lead screw 23 drives the movable part 27 to move linearly up and down along the high point mounting cavity 22 through the thread transmission. The movable part 27 pushes the buffer part 28, the top rod 29 and the connecting bearing 210 to move up and down synchronously, thereby compensating for the height deviation of the rotating shaft 11 caused by the foundation settlement, and realizing precise and stable vertical correction adjustment.

[0055] The rotation of the worm gear 26 drives the turbine 25 to rotate synchronously, and the turbine 25 then drives the lead screw 23 to rotate, thereby driving the moving part 27 to complete the lifting action. The worm gear 26 has a reverse self-locking characteristic. After the adjustment is in place, the external load cannot drive the worm gear 26 to rotate in the reverse direction, which can ensure that the adjusted position remains fixed. Combined with the self-locking characteristic of the lead screw 23 itself, a double locking is formed, which will not loosen, fall back or shift, so that the support height after settlement correction is stable for a long time, improving the reliability and safety of the support operation.

[0056] Disc springs have elastic characteristics of small stroke, large load and high rigidity. The use of multiple sets can further improve the total elastic stroke, overall load-bearing capacity and fatigue life. When uneven settlement occurs in the foundation, the support point of the rotating shaft 11 will be vertically displaced, and the disc spring will be compressed or stretched. Through elastic deformation, it will generate corresponding restoring force to offset the height difference and structural stress caused by settlement. Under the action of dynamic loads such as wind load and vibration, the disc spring can respond quickly and absorb impact energy to avoid rigid impact from being transmitted to the rotating shaft 11 and the drive mechanism. The combination of multiple disc springs can make the elastic force distribution more uniform and the deformation more stable. Long-term repeated work is not easy to produce plastic deformation or failure. It continuously maintains the pre-tight support of the top rod 29 and the connecting bearing 210 to ensure that the support height of the rotating shaft 11 is always in a stable state.

[0057] The rotating shaft 11 adopts a multi-segment structure design. Adjacent segments of the rotating shaft 11 are connected and torque is transmitted through a universal joint 15. When uneven settlement of the foundation causes height differences, axial misalignment, or angular deviations in the segments of the rotating shaft 11, the universal joint 15 can adaptively compensate in the axial, radial, and angular directions. It allows for a certain angle and radial displacement between adjacent segments of the rotating shaft 11 without affecting the stable transmission of rotational torque. During the tracking drive process, the multiple segments of the rotating shaft 11 can maintain synchronous rotation, avoiding additional bending moments, shear forces, and torsional stresses caused by misalignment or non-alignment, and preventing deformation, jamming, or breakage of the rotating shaft 11. The universal joint 15 can automatically compensate for installation errors, running deformation, and settlement deviations, ensuring good coaxiality and motion consistency of the entire long shaft, achieving synchronous tracking of the entire row of supports, and correcting the long shaft deviation.

[0058] The protective plate 222 can slide freely along the movable cavity 221, which can completely seal the opening area of ​​the low-point mounting cavity 22, blocking rainwater, dust, mud, insects and other outdoor elements from entering the mounting cavity 22, and preventing precision transmission components such as worm gear, worm 26, and lead screw 23 from being corroded, stuck or worn.

[0059] A spring 44 is fixedly installed inside the mounting rod 41. The spring 44 is in a pre-compressed state and continuously applies an elastic pushing force upward. The support rod 42 can float along the axis of the mounting rod 41 under the action of the spring 44. The upper end of the support rod 42 is fixed with a support plate 43. The support rod 42 and the support plate 43 directly support the drive assembly 3 above. When the foundation settles or the structure undergoes slight deformation, the spring 44 adaptively compensates for the height difference by extending and retracting, pushing the support rod 42 and the support plate 43 to maintain a constant support height. This ensures that the drive assembly 3 and the rotating shaft 11 always maintain a stable contact state, avoiding drive failure, tooth dislodgement, or shaking due to height deviation. This ensures continuous and stable tracking drive. The spring 44, support rod 42, and support plate 43 are linked to float and support, adaptively compensating for height deviation and ensuring stable contact of the drive.

[0060] The motor 33 is fixed on the mounting bracket 31. The output shaft of the motor 33 drives the gear 32 to rotate. The gear 32 meshes with the toothed plate 34 to transmit the rotational motion, which is converted into the linear motion of the toothed plate 34. The toothed plate 34 is slidably assembled inside the support plate 43. The support plate 43 provides guidance and limit for the toothed plate 34. The toothed plate 34 meshes with the toothed groove 35 opened on the rotating shaft 11. When the toothed plate 34 moves linearly, it drives the rotating shaft 11 to rotate around the axis through the toothed groove 35, thereby realizing the adjustment of the solar tracking angle. The elastic support of the support component 4 ensures that the toothed plate 34 and the toothed groove 35 always maintain a tight mesh, and there will be no tooth disengagement or skipping due to settlement, vibration or load changes, ensuring that the driving force is transmitted smoothly and the rotation angle of the rotating shaft 11 is precisely controllable.

[0061] A rotating frame 36 is rotatably mounted on the outer wall of the motor 33. A wind baffle 37 is fixed on the rotating frame 36 to form a wind load sensing structure. A stop plate 310 is fixed on the mounting frame 31. An elastic element 38 is set between the stop plate 310 and the rotating frame 36. The elastic element 38 is in a pre-compressed state to provide a reset force for the rotating frame 36. A reset controller 39 is installed on the stop plate 310 to detect the deflection position of the rotating frame 36 and output a control signal. When strong winds act on the photovoltaic module, the wind pressure pushes the wind baffle 37 to drive the rotating frame 36 to deflect around the outer wall of the motor 33. During the deflection process, the elastic element 38 is compressed. The elastic element 38 deforms and absorbs the wind load impact energy. When the deflection angle reaches the threshold, the rotating frame 36 triggers the reset controller 39. The controller sends a signal to control the motor 33 to perform a wind-avoiding rotation action, realizing automatic wind avoidance and automatic reset in strong winds, and improving wind resistance safety.

[0062] The mounting frame 13 provides a mounting carrier for the photovoltaic panel 14. The photovoltaic panel 14 is fixed on the connecting frame 51 and can rotate slightly with the connecting frame 51. When the telescopic rod 52 moves in extension and retraction, the output end pushes and pulls the protrusion 53, which drives the photovoltaic panel 14 to make a pitch angle fine adjustment with the connecting frame 51 as the fulcrum. Based on the overall tracking of the rotating shaft 11, the light receiving angle is further optimized, and the component installation deviation, terrain tilt angle and tracking residual error are compensated, so that the photovoltaic panel 14 always maintains the best light receiving posture. The entire fine adjustment mechanism is flexible and responsive, and can realize high-precision angle correction and light tracking optimization at the component level.

[0063] The above description represents the preferred embodiments of the present invention.
