Description

Technical Field

[0001] This application relates to the field of solar power generation technology, and further to a high-concentration photovoltaic tracking bracket and a high-concentration photovoltaic tracking system. Background Technology

[0002] Currently, high-concentration photovoltaic systems are generally equipped with tracking brackets. Through a drive mechanism, the supporting structure is rotated, so that the orientation of the high-concentration module is adjusted according to the position of the sun, thereby improving the utilization rate of light energy.

[0003] Existing load-bearing structures typically include several components for supporting and installing high-concentration light modules. However, in practical applications, these load-bearing structures often use conventional purlin structures to support the high-concentration light modules in terms of arrangement and connection. This can easily lead to insufficient overall rigidity or structural deformation during long-term operation, thereby affecting the stable fixation and normal tracking of the high-concentration light modules.

The plurality of purlins are spaced apart along a third direction and fixedly connected to the support frame. The third direction is perpendicular to both the first direction and the second direction. The support frame and the purlins are arranged in an alternating manner to form a support frame for supporting the high-concentration light module. The drive mechanism can drive the main shaft and the support frame to rotate.

[0011] In some embodiments, the high-concentration tracking bracket further includes several limiting components, which are respectively fixedly connected to the support frame;

[0014] The end block includes a first fixing part and a first limiting part. The first fixing part is fixedly connected to the purlin. The first limiting part extends from the central axis of the first fixing part in a direction away from the central axis and is used to abut against the frame of the high-concentration light-gathering module. Each end block includes two first limiting parts. The two first limiting parts are symmetrically arranged on opposite sides of the first fixing part and are respectively connected to the first fixing part through a bending section.

[0018] The middle stop block is provided with a second fixing part, which is fixedly connected to the purlin. The middle stop block includes at least two second limiting parts and at least two third limiting parts, which are symmetrically arranged on the circumferential position of the second fixing part.

[0019] In some embodiments, the high-concentration tracking bracket includes fasteners for fixing the limiting groove at the bottom of the high-concentration module to the purlin.

[0020] The fastener includes a rod and a head. The rod passes through a bolt hole on the purlin and is fixed with a nut. The head extends into the limiting groove. The head includes a guide and an abutment. The guide and the abutment are respectively arranged around the periphery of the head. The guide is used to guide the head to rotate within the limiting groove, and the abutment is used to abut against the groove wall of the limiting groove.

[0021] In some embodiments, the drive mechanism is a dual-axis drive mechanism, including a first drive component and a second drive component.

[0052] Currently, high-concentration photovoltaic systems generally use tracking brackets with drive mechanisms, which achieve the tracking function of the high-concentration module through the rotation of the load-bearing structure.

[0053] Existing load-bearing structures typically include several components for supporting and mounting high-concentration photovoltaic modules. However, in practical applications, these load-bearing structures often employ conventional purlin structures to support the modules. Due to the simple arrangement and fixed connection positions of the purlins, they are prone to insufficient overall rigidity or localized deformation during long-term operation due to wind loads, temperature variations, and gravity. When the load-bearing structure deforms, it may cause the installation position of the high-concentration photovoltaic module to shift, affecting its optical alignment accuracy, thereby reducing light energy utilization and system operational stability.

[0054] In one embodiment, refer to the appendix to the specification. Figure 1 This application describes a high-concentration tracking bracket that optimizes the bracket structure, thereby improving overall rigidity and operational reliability.

[0055] Reference manual attached Figure 1 The high-concentration tracking bracket provided in this application is used for the installation and fixation of the high-concentration module 6. Under the premise of ensuring structural strength and stability, it can achieve precise orientation adjustment of the high-concentration module 6 to improve optical alignment accuracy and light energy utilization efficiency.

[0056] Reference Appendix Figure 2The high-magnification focusing tracking bracket includes a main shaft 1, a column 2, a drive mechanism 3, at least two support frames 4, and several purlins 5. The main shaft 1 extends along a second direction and is supported by the column 2 extending along a first direction. The column 2 is fixedly installed in a preset position and has sufficient supporting rigidity to support the main shaft 1 and various components arranged on it. The drive mechanism 3 is installed between the column 2 and the main shaft 1 and is drively connected to the main shaft 1. The output of the drive mechanism 3 can act on the main shaft 1, causing the main shaft 1 to rotate around its own axis.

[0057] The number of support frames 4 can be one or more. The length direction of each support frame 4 is consistent with the third direction, which is perpendicular to both the axial direction (second direction) and the first direction of the main shaft 1. As shown in the figure, multiple support frames 4 are distributed at intervals along the second direction on the main shaft 1 and extend to both sides with the column 2 as the central axis. This allows the support frames 4 to span both sides of the main shaft 1, providing dual-sided load-bearing capacity, thereby achieving better mechanical balance and structural stability when arranging the high-concentration light module 6.

[0058] A number of purlins 5 are arranged on the support frame 4. The length direction of the purlins 5 is consistent with the second direction and they are arranged at intervals along the third direction. Each purlin 5 is fixedly connected to a different position on the support frame 4, so that the support frame 4 and the purlins 5 form a cross-sectional arrangement in space, thereby forming a support frame for supporting the high-concentration light module 6.

[0059] Through the configuration of this embodiment, the staggered arrangement of the support frame 4 and purlin 5 can form a grid-like support structure, which can evenly distribute the self-weight and external load of each high-concentration photovoltaic module 6, significantly improve the overall rigidity, reduce the deformation of local components due to stress concentration, and thus effectively solve the problems of insufficient rigidity of the load-bearing structure, easy deformation during long-term operation and poor stability in the prior art, providing a reliable guarantee for the efficient and stable operation of the photovoltaic system.

[0060] In addition, the support frame 4 extends to both sides with the main shaft 1 as the central axis, which can maintain the balance of the load-bearing frame under the action of asymmetrical external forces such as wind load, reduce deflection and vibration, and thus improve tracking accuracy and operational reliability. At the same time, the drive mechanism 3 can quickly respond to the system's commands and realize real-time adjustment of the orientation of the high-concentration module 6, which is conducive to maintaining the optimal light incident angle and improving photoelectric conversion efficiency.

[0061] In practical implementation, the connection between the support frame 4 and the purlin 5 can be achieved through various methods such as bolt connection or profile insertion, to adapt to different construction conditions and structural strength requirements. A bearing assembly can be installed between the main shaft 1 and the column 2 to reduce rotational resistance. The drive mechanism 3 can be an electric drive unit, a hydraulic drive unit, or other drive devices that can provide stable torque.

[0062] It should be noted that the length of the support frame 4, the spacing between the purlins 5, and their relative positions can be adjusted according to the size and weight of the high-concentration light module 6 to ensure optimal stress distribution and installation density.

[0063] Based on the above, such as Figure 3 As shown, the high-concentration tracking bracket also includes several limiting components 7, which are fixedly connected to corresponding positions on the supporting frame. In use, the limiting components 7 are arranged on the outside of the frame 61 of the high-concentration module 6, so that a reliable limiting fit is formed between the limiting components 7 and the frame 61.

[0064] When external loads are applied to the high-concentration photovoltaic module 6, such as wind pressure, snow pressure, or stress caused by temperature changes, the limiting component 7 forms a barrier around the outer perimeter of the frame 61 to prevent displacement of the high-concentration photovoltaic module 6, thereby effectively maintaining the stability of its installation position. This design reduces alignment errors caused by the accumulation of minute displacements of the high-concentration photovoltaic module 6 during operation, ensuring the working accuracy of the high-concentration photovoltaic tracking system. Furthermore, it prevents the high-concentration photovoltaic module 6 from loosening or even falling off under extreme weather conditions, improving the safety and reliability of the entire high-concentration photovoltaic tracking system.

[0065] Furthermore, the relative fixing method between the limiting component 7 and the supporting frame can be adjusted according to the specifications of different high-concentration light-gathering modules 6 to ensure that a stable limiting effect can be provided in the application of high-concentration light-gathering modules 6 of different sizes and arrangements, thereby enhancing the applicability and versatility of the high-concentration light-gathering tracking bracket.

[0066] In this embodiment, the limiting component 7 can be installed on different components of the supporting frame. Preferably, as shown in the accompanying drawings, the limiting component 7 is set on the purlin 5 at a position corresponding to the end of the frame 61 and forms a fixed connection with the purlin 5. In addition, the limiting component 7 can also be set on the top of the support frame 4 or other positions adjacent to the frame 61 according to the actual force requirements.

[0067] In addition, in order to adapt to changes in different module sizes and installation spacing, multiple mounting holes or elongated adjustment holes are pre-set on the purlins 5 and support frames 4. The limiting component 7 can be adjusted between different holes by connecting parts such as bolts and screws, so that the limiting position can be quickly adjusted according to the actual size during on-site construction, thereby improving the installation adaptability and the convenience of later maintenance.

[0068] In specific applications, the limiting component 7 includes a baffle structure. The limiting surface of the baffle is arranged facing the frame 61 and forms a perpendicular or approximately perpendicular relationship with the frame 61, thereby providing a barrier when the high-concentration module 6 is subjected to external loads and has a tendency to move laterally.

[0069] In another form, the limiting component 7 is a split limiting block. Its main body is fixed to the mounting surface of the purlin 5 or support frame 4 by bolts, and a local protrusion is formed on its outer side, which can partially abut against the frame 61, thereby achieving limiting while reducing the impact on the module assembly and disassembly space. These limiting components 7 with different structural forms can be used individually or combined on the same load-bearing frame to meet the limiting requirements of different positions while achieving stable support and high reliability of the overall structure.

[0070] In one embodiment, such as Figure 4 and Figure 5 As shown, the limiting component 7 includes several end blocks 71, which are respectively disposed at one or both ends of the purlin 5, thereby forming a stable endodirectional limit at the edge of the load-bearing frame.

[0071] Each end block 71 includes a first fixing part 711 and a first limiting part 712. The first fixing part 711 cooperates with and abuts against the end structure of the purlin 5, and the end block 71 is fixed to the purlin 5 by means of bolt connection, riveting or welding. The first limiting part 712 extends from the central axis of the first fixing part 711 in a direction away from the central axis, forming an extension section. In the installed state, the first limiting part 712 is located outside the frame 61 of the high-concentration light module 6 and abuts against the frame 61, thereby forming an effective limiting end.

[0072] When the high-concentration module 6 is subjected to external loads (such as wind load, snow load, or thermal expansion and contraction) and tends to displace along the length direction (second direction) of the purlin 5, the first limiting part 712 can block the displacement in time, preventing the module from falling off or misaligning, which helps to ensure the structural stability and safety of the high-concentration system during long-term operation.

[0073] It should be noted that, in this embodiment, the extension length and shape of the first limiting part 712 can be adjusted according to the height of the frame 61 and the installation position of the purlin 5 to adapt to high-concentration light modules 6 of different models and sizes. The first limiting part 712 can be designed as a straight line, an arc, or a structure with reinforcing ribs to improve the limiting strength.

[0074] Based on the above, in one embodiment, each end block 71 includes a first fixing part 711 and two first limiting parts 712. The two first limiting parts 712 are located on opposite sides of the first fixing part 711 and are symmetrically distributed along the central axis of the end block 71.

[0075] The first fixing part 711 matches and abuts against the top structure of the purlin 5, and can be fixed to the purlin 5 by means of screwing or snap-fitting to ensure the stable installation of the end block 71 during operation; the two first limiting parts 712 are respectively connected to the first fixing part 711 through the bending section 713 and extend in a direction away from the central axis of the end block 71. In the installed state, they are located outside the frame 61 of the high-concentration light module 6 to ensure that the end block 71 is subjected to uniform and stable force and improve the reliability of the limiting component 7.

[0076] For reference, see the appendix. Figure 4 and Figure 14 The purlin 5 includes a main body 50 and an extension 51. The main body 50 extends continuously along the length of the purlin 5 and is fixedly connected to the limiting component 7. The main body 50 is provided with an opening groove 500 that faces downwards. The opening groove 500 can reduce the weight of the purlin structure to a certain extent.

[0077] The extension 51 extends from the end of the main body 50 in a direction away from the main body 50 and is fixedly connected to the support frame 4, forming an installation edge for supporting the high-concentration light module 6. The extension 51 allows the high-concentration light module 6 to be stably mounted on the purlin 5. The high-concentration light module 6 is positioned on the extension 51 and abuts against the side wall of the main body 50. The main body 50 supports the high-concentration light module 6 while also limiting its position, preventing displacement along a third direction. Simultaneously, the extension 51 and the main body 50 form a bent cross-sectional structure, giving the purlin 5 good overall bending resistance and local pressure-bearing capacity, preventing significant deformation of the high-concentration light module 6 under long-term load.

[0078] Through the combination of the main body 50 and the extension 51, the purlin 5 maintains a lightweight design while also possessing high load-bearing strength. Both the main body 50 and the extension 51 provide support for the installation of the high-concentration light module 6.

[0079] In this application, the purlin 5 adopts a Z-shaped cross-section structure. In other embodiments, the purlin 5 may also adopt an I-shaped, channel steel-shaped, or other cross-section structures with reinforced folded edges to meet the application requirements under different working conditions. Specifically, the selection can be matched according to the size and weight of the high-concentration module 6 and the overall arrangement of the bracket to further optimize the structural performance.

[0080] Based on the above, in one embodiment, the outer contour of the first fixing part 711 is adapted to the contour of the main body part 50 of the purlin 5. Through the arrangement of the bending section 713, the end block 71 as a whole forms a shape similar to a C shape. The two first limiting parts 712 extend outward from the bending section 713 and are respectively located outside the purlin 5. After the high-concentration light module 6 is installed on the extension part 51 of the purlin 5, the first limiting part 712 can abut against the frame 61 to form stable lateral limiting. It can improve the anti-displacement ability of the high-concentration light module 6 in the end area 401 while keeping the overall structure layout compact, and reduce the loosening risk of the high-concentration light module 6.

[0081] Optionally, a buffer gasket or a flexible coating layer is provided at the part where the first limiting part 712 contacts the high-concentration light module 6 to reduce frictional wear and buffer external force impacts. In addition, the fixed connection between the first fixing part 711 and the purlin 5 can be realized by a bolt assembly corresponding to the hole positions at the end of the purlin 5, and the installation position can be adjusted according to the on-site layout requirements, thereby enhancing the adaptability and maintainability of the end block 71.

[0082] In one embodiment, as Figure 6 and Figure 7 shown, the limiting component 7 includes several middle blocks 72, and the several middle blocks 72 are distributed along the length direction of the purlin 5 and are respectively fixedly connected to different positions of the purlin 5.

[0083] Among them, each middle block 72 is provided with multiple limiting parts, and the limiting parts can be adapted to the end side edges or corner parts of the frames 61 of adjacent high-concentration light modules 6. Specifically, in the installed state, the limiting parts abut against the ends of the frames 61, and the multiple limiting parts can perform limiting cooperation on the relative positions of two or more adjacent high-concentration light modules 6 arranged adjacent to each other, so as to form stable positioning constraints between the high-concentration light modules 6.

[0084] It can be understood that by setting the above structure, not only can the relative displacement between adjacent modules be avoided on the premise of ensuring the close arrangement of the modules, but also the module misalignment or collision caused by external loads can be effectively resisted, thereby improving the structural stability of the overall support structure during long-term operation.

[0085] Furthermore, the fixed connection position of the middle block 72 can be flexibly adjusted according to the required module arrangement. For example, on the same purlin 5, the middle block 72 can be selectively installed at multiple preset installation hole positions to adapt to high-concentration light module arrays of different specifications and sizes.

[0086] In one embodiment, the center of the central stop 72 is provided with a second fixing part 721, which is fixedly connected to the purlin 5. Specifically, the central stop 72 can be securely installed to the purlin 5 by bolts, riveting, welding, or snap-fit ​​structures, so that the central stop 72 is not easy to loosen or shift when subjected to external forces, thus ensuring that the central stop 72 will not loosen or shift due to external forces such as vibration, wind load, or thermal expansion and contraction during long-term operation. Therefore, during long-term operation, the central stop 72 can continuously and effectively limit the position of the high-concentration module 6 to ensure the normal working state of the bracket.

[0087] For details, please refer to the attached instruction manual. Figure 7 The middle stop block 72 is provided with a second limiting part 722. The second limiting part 722 is located on the side of the frame 61 perpendicular to the length direction of the purlin 5. That is, the second limiting part 722 extends away from the second fixing part 721 along the third direction (i.e., perpendicular to the length direction of the purlin 5). In this way, through the direct contact between the second limiting part 722 and the frame 61 of the high-concentration light module 6 perpendicular to the length direction of the purlin 5, an effective barrier can be formed on the high-concentration light module 6 in the third direction, thereby preventing it from loosening and shifting along the second direction due to wind load, vibration or temperature changes during operation.

[0088] Please refer to the instruction manual attached. Figure 7 Each central stop 72 is provided with not only a second limiting part 722, but also a third limiting part 723. The third limiting part 723 is arranged perpendicular to the second limiting part 722, that is, the second limiting part 723 extends away from the second fixing part 721 along the second direction. The second limiting part 722 is used to abut against the side frame 61 of the high-concentration light-gathering module 6 perpendicular to the length direction of the purlin 5, while the third limiting part 723 is used to abut against the side frame 61 of the high-concentration light-gathering module 6 parallel to the length direction of the purlin 5. This allows the central stop 72 to provide limiting function in two mutually perpendicular second directions and a third direction, thereby constraining the position of the high-concentration light-gathering module 6 in a two-dimensional plane and significantly improving the stability of the structure.

[0089] Furthermore, the central stop 72 includes at least two second limiting parts 722 and at least two third limiting parts 723, with the second limiting parts 722 and the third limiting parts 723 symmetrically arranged in the circumferential position of the central stop 72.

[0090] Specifically, such as Figure 7As shown, the central block 72 is symmetrically provided with two second limiting parts 722 and two third limiting parts 723. Through this symmetrical arrangement, the central block 72 forms a cross-shaped structure. The limiting parts cooperate with each other to form a stable barrier between the frames 61 of the adjacent high-concentration light-gathering modules 6.

[0091] Thus, when the high-concentration light-gathering module 6 is installed in place, the second limiting part 722 and the third limiting part 723 correspond to the frame 61 in different directions, and the two work together to effectively prevent the high-concentration light-gathering module 6 from being displaced relative to each other in the second and third directions.

[0092] Understandably, the central block 72 in this embodiment, through its bidirectional limiting design, can largely avoid the risk of misalignment or collision of the high-concentration module 6 caused by wind load, temperature difference deformation, or vibration factors, thereby reducing the impact on the concentration effect and power generation efficiency, and significantly reducing the frequency of inspection and maintenance during long-term operation.

[0093] In one embodiment, refer to the appendix to the specification. Figures 8 to 10 The high-concentration beam tracking bracket is equipped with fasteners 8 for connecting the high-concentration beam module 6 and the purlin 5. The fasteners 8 are used to fix the limiting groove 60 at the bottom of the high-concentration beam module 6 to the purlin 5. The limiting groove 60 is circumferentially arranged along the frame 61 of the high-concentration beam module 6. The fasteners 8 include a connected rod 82 and a head 81. During installation, the rod 82 passes through the pre-set bolt hole on the purlin 5 and is fixed with a nut, so that the overall connection has a high locking force and facilitates subsequent disassembly and replacement.

[0094] The head 81 of the fastener 8 is used to connect with the limiting groove 60 at the bottom of the high-concentration light module 6, and its shape and size are matched with the internal structure of the limiting groove 60. The head 81 includes at least one guide portion 810 and at least one abutment portion 811, which are respectively arranged at the periphery of the head 81.

[0095] After the head 81 is inserted into the limiting groove 60, the guide part 810 can guide the head 81 to rotate along the groove wall of the limiting groove 60 during the installation process until it reaches the preset installation position, significantly reducing the risk of jamming during installation and reducing wear on the groove wall of the limiting groove 60. After the head 81 rotates into place, the abutment part 811 forms a stable abutment with the groove wall of the limiting groove 60 at the preset position, forming a surface contact or line contact, restricting further rotation of the fastener 8.

[0096] Thus, the design of this embodiment not only simplifies the installation process and improves assembly efficiency, but also effectively ensures the installation accuracy and operational stability of the high-concentration module. Furthermore, the relative rotation design between the head 81 and the limiting groove 60 allows installers to complete the fixing operation within a limited space, reducing restrictions on the angle and space of installation tools and improving the flexibility and adaptability of on-site construction.

[0097] Optionally, the head 81 and the rod 82 of the fastener 8 can be integrally formed or detachably connected to facilitate quick replacement between high-magnification focusing modules 6 of different specifications. Only the head 81 needs to be adjusted to fit the size of different limiting grooves 60.

[0098] Based on the above embodiments, in one embodiment, such as Figure 9 As shown, the limiting groove 60 includes a first groove 601 and a second groove 602 that are interconnected. The first groove 601 is located at the opening of the limiting groove 60 and is closer to the opening than the second groove 602, so that the component that enters is accommodated first during the installation process.

[0099] The head 81 of the fastener 8 is structurally matched with the limiting groove 60, and its width is not greater than the width of the first groove 601, so as to ensure that the head 81 can fall smoothly into the first groove 601 and be stably accommodated in that position. At the same time, the limit dimension of the head 81 in the length direction is equal to the width of the second groove 602, so that when the head 81 rotates to the preset position, the abutment part 811 can abut against the groove wall of the second groove 602, so as to achieve reliable rotation limiting and prevent the head 81 from continuing to rotate outside the preset position, thereby maintaining the fixed relationship between the high-concentration light module 6 and the purlin 5.

[0100] In one practical configuration, the head 81 is inserted along the length direction of the limiting groove 60 during installation, first entering the first groove 601, at which point the length direction of the head 81 is consistent with the length direction of the limiting groove 60. For example, Figure 10 The head 81 has two guide parts 810 and two abutting parts 811 around its periphery, which are arranged alternately along the circumference, such that each guide part 810 and abutting part 811 is located at opposite diagonal positions.

[0101] During the initial insertion phase, the two guide portions 810 have arc-shaped contours, which guide the head 81 to rotate clockwise or counterclockwise within the groove; while the two abutment portions 811 maintain a gap with the groove wall of the second groove 602 at this time. After the installer inserts the head 81 into place, the fastener 8 is rotated 90 degrees in the preset direction, and the abutment portion 811 enters the second groove 602 through the communication position between the first groove 601 and the second groove 602, and forms a stable abutment with the groove wall of the second groove 602 when it is in place.

[0102] Thus, this structural design not only ensures the guiding accuracy during installation and reduces the risk of jamming or scratching, but also ensures that the head 81 can obtain a stable radial limiting effect after reaching the preset limit position, avoiding loosening or misalignment during operation.

[0103] In one embodiment, the drive mechanism 3 is a dual-axis drive mechanism, as shown in the attached diagram. Figure 1 and Figure 11 It includes a first drive assembly 31 and a second drive assembly 32. The first drive assembly 31 is used to drive the main shaft 1 to rotate around its own axis (second direction) to adjust the pitch angle; the second drive assembly 32 is used to drive the main shaft 1 to rotate around the axis (first direction) of the column 2 to adjust the azimuth angle.

[0104] By setting up a dual-axis drive mechanism, the high-concentration tracking bracket can achieve independent rotation control in two mutually perpendicular directions. This allows for adjustments based on the changes in azimuth and altitude angles of the sun throughout its celestial trajectory, effectively improving the orientation accuracy and light energy utilization of the high-concentration module 6.

[0105] Compared with the single-axis drive structure, the dual-axis drive method can not only achieve continuous adjustment of the orientation of the focusing module over a wider range, avoiding the problem that the single-axis drive structure cannot achieve optimal light tracking in a specific time period, but also reduce the drive stroke through two-axis coordinated control, improve response speed and positioning accuracy, and ensure stable operation under variable weather conditions.

[0106] Based on the above embodiments, such as Figure 11 The second drive assembly 32 includes an angle limiting device 321, which is used to precisely limit the rotation range of the main shaft 1 during rotation around the axis of the column 2, so as to prevent the structure from rotating excessively during operation, causing mechanical interference or damage.

[0107] The angle limiting device 321 includes a position detection module 322 and a trigger 323. The position detection module 322 is fixedly installed on the column 2 or the fixed end of the second drive assembly 32 and is used to monitor the position of the trigger 323 during rotation. The trigger 323 is connected to the output end of the second drive assembly 32 and can rotate synchronously with the output end. When the spindle 1 rotates around the axis of the column 2 to the boundary of the preset angle range under the drive of the second drive assembly 32, the trigger 323 will enter the sensing range of the position detection module 322. At this time, the position detection module 322 detects the trigger 323 and immediately sends a control signal to the controller, thereby controlling the second drive assembly 32 to stop driving or reverse driving, thus effectively limiting the rotation angle.

[0108] In this application, the structure can achieve non-contact or contact position sensing at the movement limits of the mechanical structure, ensuring that the high-magnification focusing tracking bracket will not exceed the safe range during rotation, thereby avoiding problems such as component collision, support component bending or transmission mechanism damage caused by excessive rotation.

[0109] Optionally, the position detection module 322 can be in the form of a photoelectric sensor, proximity switch, or Hall element, etc., and a suitable detection method can be selected according to different environmental requirements to adapt to stable operation under complex outdoor lighting and temperature and humidity conditions. The trigger 323 can be a metal baffle, magnetic element, or reflector, and is fixed on the output shaft of the second drive assembly 32 or a component that rotates synchronously with it.

[0110] In another optional expansion method, by adjusting the number and distribution of the trigger elements 323, it is also possible to flexibly set the limit positions under different rotation ranges. Specifically, the trigger elements 323 can be evenly or unevenly distributed along the circumferential direction of the output end of the second drive component 32, with each trigger element 323 corresponding to a different rotation angle position, which is suitable for changing the setting value of the angle limit.

[0111] For example, under certain operating conditions, it may be necessary to reduce the rotation range of the spindle 1 to prevent deflection caused by external interference; while in other cases, it may be necessary to expand the rotation range to adapt to seasonal changes in lighting. This expandable and adjustable trigger 323 allows for rapid adjustments without replacing major structural components, improving the system's adaptability and flexibility.

[0112] In one embodiment, such as Figure 12 and Figure 13 As shown, the support frame 4 includes a top connecting rod 41 and a bottom connecting rod 42, which are connected and supported by several auxiliary struts 43. The auxiliary struts 43 are inclined relative to the top connecting rod 41 and the bottom connecting rod 42. This arrangement not only provides additional support in the vertical direction, but also forms a stable triangular support structure in the support frame 4, thereby effectively improving the overall deformation resistance and load-bearing stability of the support frame 4.

[0113] Several connecting parts 11 are fixedly provided on the outer circumferential surface of the main shaft 1, and the number of connecting parts 11 corresponds to the number of support frames 4. The upper edge of each connecting part 11 is fixedly connected to the top connecting rod 41 of the corresponding support frame 4, and the lower edge is fixedly connected to the corresponding bottom connecting rod 42. This ensures a stable connection between the main shaft 1 and the support frame 4, and can also effectively distribute the load when the main shaft 1 drives the support frame 4 to rotate, reduce local stress concentration, and extend the service life of the connecting parts 11 and the overall structure.

[0114] Through the above structural design, this solution can provide higher overall structural strength and wind resistance during the installation and tracking operation of the high-concentration module 6, and avoid the support frame 4 from loosening, deformation or even failure due to long-term stress or external impact.

[0115] Meanwhile, the inclined auxiliary struts 43 can provide multi-directional support when the load direction changes, improving the overall dynamic stability. They are particularly suitable for high-concentration photovoltaic tracking systems that operate outdoors for extended periods in environments with large wind and temperature variations.

[0116] Refer to the attached drawings in the instruction manual. Reinforcing ribs 111 are arranged in the connection area between the connecting part 11 and the main shaft 1 to expand the stress-bearing area, disperse stress, and improve local bending and torsional resistance. The number, cross-sectional shape, and arrangement angle of the reinforcing ribs 111 can be optimized and determined according to the design load and manufacturing process.

[0117] In a preferred embodiment, the connecting part 11 is a plate-shaped component and is arranged in a direction perpendicular to the axis of the main shaft 1. It can be connected to the main shaft 1 by means of welding or other methods to form an integral part, thereby effectively improving the wind resistance and fatigue life of the overall structure and ensuring the stability of operation.

[0118] In one embodiment, such as Figure 13 The support frame 4 has two end regions 401 along its length and a middle region 402 located between the two end regions 401. The width dimension of the middle region 402 is larger than the width dimension of either end region 401, so that the entire support frame 4 presents a shape structure that is wide in the middle and narrow at both ends.

[0119] By employing the aforementioned design that is wider in the middle and narrower at both ends, a larger load-bearing area and a higher moment of inertia can be provided in the central region 402 of the support frame 4, thereby effectively improving the bending stiffness and torsional resistance of this region when bearing components such as the high-concentration light module 6 and purlins 5. Since the central region 402 is usually located near the connection point between the column 2 and the main shaft 1, it is a concentrated area of ​​structural stress. Therefore, increasing the width of the central region can create stronger rigid support at this location, reducing the risk of local deformation and loosening of connections during operation.

[0120] Meanwhile, the narrower width design of the end area 401 can effectively reduce the structural weight and material usage, and provide more flexible conditions for the rotation space and component arrangement on both sides, thereby optimizing the balance between overall weight and strength, avoiding warping or swaying caused by uneven distribution of overall stiffness, and helping to extend the service life of the support frame 4 and its connecting parts.

[0121] In a specific implementation, the transition between the central region 402 and the end region 401 can be a straight transition, a curved transition, or a stepped transition. The specific shape can be selected according to the processing technology and strength requirements, and no specific restrictions are imposed in this embodiment. For example, when using profile extrusion or bending forming, the size can be changed through a zigzag structure to facilitate processing.

[0122] In one embodiment, please refer to the appendix to the specification. Figure 1 According to another aspect of this application, a high-concentration photovoltaic tracking system is further provided. The high-concentration photovoltaic tracking system includes a plurality of high-concentration modules 6 and a corresponding high-concentration tracking bracket. Each high-concentration module 6 includes a concentrating layer at the top, capable of efficiently concentrating incident sunlight onto the photovoltaic cell unit to improve power generation efficiency. Simultaneously, the high-concentration tracking bracket described above is used for installing and fixing the high-concentration modules 6.

[0123] Several high-concentration light-gathering modules 6 are respectively mounted on the purlins 5 of the high-concentration light-gathering tracking bracket. The purlins 5 form a load-bearing frame with the cooperation of the support frame 4 and the main shaft 1, and are reliably connected to the frame 61 of the high-concentration light-gathering modules 6, providing a stable mounting base and ensuring the positional stability and uniform stress distribution of the components during operation. Because the purlins 5 are spaced apart in the third direction and staggered with the support frame 4, multiple high-concentration light-gathering modules 6 can be evenly distributed along the entire load-bearing frame.

[0124] In addition, the high-magnification focusing tracking bracket mentioned above can also be used in conjunction with limiting components 7, fasteners 8, etc., which can effectively prevent component displacement, loosening or falling off under the influence of external environmental factors such as wind load, snow load or temperature changes, and ensure the accuracy of optical focusing position and the safety of system operation.

[0125] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
