Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic power generation equipment technology, specifically a rotating structure for a single-axis tracking bracket. Background Technology

[0002] A photovoltaic bearing structure is a bearing structure used in photovoltaic modules. Currently, with the continuous development of technology, a typical large single-axis photovoltaic support uses a long and sturdy rotating beam to load numerous photovoltaic modules. The long and sturdy rotating beam passes through several bearings, which are installed on several columns standing on the ground to ensure the stable operation of the rotating beam.

[0003] For example, Chinese patent publication number CN111628709B discloses a main beam and bearing assembly for a photovoltaic tracking bracket and a photovoltaic tracking bracket. The main beam and bearing assembly includes a support base, a main beam, an upper bearing, and a blocking component. The support base is used to install on the column of the photovoltaic tracking bracket and has a through-hole. The main beam is inserted into the through-hole. The upper bearing is inserted into the through-hole and located in the gap between the main beam and the support base. One end of the upper bearing has a shoulder protruding from its upper surface, which abuts against one end of the support base. The other end of the upper bearing has a groove. The blocking component engages with the groove, and the part extending out of the groove abuts against the other end of the support base. In this invention, the two ends of the upper bearing are limited by the shoulder and the blocking component, respectively. There is no relative displacement space between the upper bearing and the support base. Even if the main beam and the column undergo relative displacement, the upper bearing will not have relative displacement with the support base, reducing safety hazards.

[0004] However, the above structure still has many shortcomings in use. First, the upper bearing is limited by shoulders and blocking parts at both ends, and the position of each component needs to be precisely operated during installation, which requires high installation accuracy and increases the difficulty of installation.

[0005] Secondly, the process of removing and reinstalling the blocking components when maintaining or replacing bearings is complicated and requires special tools. Furthermore, the reinstallation must be precise, otherwise the limiting effect will be affected.

[0006] Furthermore, to ensure the reliability of the limiting structure, the strength and wear resistance of the materials of related components are required to be high, which leads to an increase in the cost of raw material procurement. The complex structure also increases the cost of parts processing and overall manufacturing.

[0007] In addition, the upper bearing is strictly limited at both ends. The internal stress generated by the thermal expansion and contraction of each component at different temperatures cannot be relieved by the relative displacement of the upper bearing. Long-term accumulation may cause the components to deform and be damaged, shortening their service life.

[0008] Finally, during the rotation of the main beam, the presence of the limiting structure will increase the frictional resistance. The additional frictional resistance will affect the tracking accuracy and operating efficiency of the photovoltaic tracking bracket, requiring a greater driving force to achieve the rotation of the main beam. Utility Model Content

[0009] The main technical problem to be solved by this utility model is to provide a single-axis tracking bracket rotation structure that is simple in structure, easy to install, easy to maintain, low in manufacturing cost, easy to process, highly adaptable to the environment, accurate in tracking, and highly efficient in operation.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0011] A rotating structure for a single-axis tracking bracket includes a support base, which is a closed circular ring with its inner and outer edges arranged concentrically and a circular radial cross-section. The main beam of the tracking bracket is coaxially inserted into the support base. A split slider is provided in the radial gap between the main beam and the support base, allowing the main beam to rotate around the axis of the support base. The split slider includes an upper slider and a lower slider, the inner walls of which are fixedly connected to the main beam, and arc-shaped limiting grooves are respectively formed on their outer walls. The inner walls of the arc-shaped limiting grooves cover the outer circumferential surface of the support base, forming a sliding fit structure. A support member for connecting the column of the tracking bracket is welded to the bottom of the support base.

[0012] The following are further optimizations of the above technical solution by this utility model:

[0013] The upper slider includes a detachably connected upper slider body and a mounting block. The arc-shaped limiting groove on the outer side wall of the upper slider body is slidably connected to the support seat, and the inner side wall of the mounting block is fixedly connected to the main beam by compression.

[0014] Further optimization: A connecting plate is integrally connected to the upper slider body, and a connecting groove adapted to the connecting plate is opened on the mounting block.

[0015] Further optimization: The connecting plate has a first connecting hole, and the mounting block has a second connecting hole. When the connecting plate is fully inserted into the connecting groove, the first connecting hole and the second connecting hole are coaxially aligned and fixedly connected by fasteners.

[0016] Further optimization: The support member is a C-shaped steel structure, and multiple waist-shaped adjustment holes are evenly opened along its height direction. The length direction of the waist-shaped adjustment holes is perpendicular to the axis direction of the support member.

[0017] Further optimization: The support member is connected to the column by fasteners. The column has multiple circular holes corresponding to the waist-shaped adjustment holes along the height direction. The circular holes are arranged at equal intervals along the axial direction of the column.

[0018] Further optimization: The support component alternatively includes a fixing plate welded to the bottom of the support base, and the bottom of the fixing plate is fixedly connected to an inverted U-shaped mounting bracket. The mounting bracket has symmetrical mounting hole groups on both side walls, and the mounting hole groups include a first limiting hole and an arc-shaped hole.

[0019] Further optimization: The column is symmetrically provided with a group of connecting holes on both sides. The group of connecting holes includes two second limiting holes. One of the second limiting holes is connected to the arc-shaped hole by a fastener, and the other second limiting hole is connected to the first limiting hole by a fastener.

[0020] This invention achieves stable 360-degree full circumferential support through the coaxial structure formed by the closed circular ring support base and the main beam, combined with the design of the split slider. This structure can evenly distribute the load, significantly improving the support's resistance to wind load and deformation, and is particularly suitable for maintaining stable operation under harsh weather conditions.

[0021] In this invention, the arc-shaped limiting grooves of the upper and lower sliders form a wrapping sliding fit with the support base. This structure not only enhances rotational stability but also effectively prevents the main beam from shifting or swaying during rotation. At the same time, the symmetrical arrangement of the two sliders also realizes the automatic centering function, which greatly reduces the installation accuracy requirements and makes installation and debugging simpler.

[0022] In this invention, the split slider structure allows for the individual replacement of worn parts without the need for overall disassembly, which greatly reduces maintenance costs and time, making the rotating structure particularly suitable for long-term use in harsh environments such as deserts and coastal areas.

[0023] In this invention, the relative displacement space of the split slider can effectively alleviate the internal stress caused by the thermal expansion and contraction of each component at different temperatures, prevent the components from deforming and being damaged due to the accumulation of internal stress, extend their service life, and ensure the long-term stable operation of the photovoltaic system.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1: As Figure 1-7As shown, a rotating structure for a single-axis tracking bracket includes a support base 1, which is a closed circular ring with its inner and outer edges arranged in concentric circles and a circular radial cross-section. The main beam 2 of the tracking bracket is coaxially inserted into the support base 1. A split slider 3 is provided in the radial gap between the main beam 2 and the support base 1, and the split slider 3 allows the main beam 2 to rotate around the axis of the support base 1. The split slider 3 includes an upper slider 31 and a lower slider 32. The inner sidewalls of the upper slider 31 and the lower slider 32 are fixedly connected to the main beam 2, and the outer sidewalls are respectively provided with arc-shaped limiting grooves 311 and 321. The inner walls of the arc-shaped limiting grooves 311 and 321 cover the outer peripheral surface of the support base 1, forming a sliding fit structure.

[0039] This design, firstly, the coaxial structure formed by the closed circular ring support seat 1 and the main beam 2, combined with the design of the split slider 3, achieves stable support in all 360 degrees. This structure can evenly distribute the load, significantly improving the support's resistance to wind load and deformation, and is particularly suitable for maintaining stable operation under harsh weather conditions.

[0040] Secondly, the arc-shaped limiting grooves 311 and 321 of the upper slider 31 and the lower slider 32 form a wrapping sliding fit with the support seat 1. This structure not only enhances rotational stability, but also effectively prevents the main beam 2 from shifting or swaying during rotation. At the same time, the symmetrical arrangement of the two sliders also realizes the automatic centering function, which greatly reduces the installation accuracy requirements and makes installation and debugging more convenient.

[0041] Furthermore, the split slider 3 adopts a split structure, which allows for the individual replacement of worn parts without the need for overall disassembly, greatly reducing maintenance costs and time. This makes the rotating structure particularly suitable for long-term use in harsh environments such as deserts and coastal areas.

[0042] Finally, the relative displacement space of the split slider 3 can effectively alleviate the internal stress caused by the thermal expansion and contraction of each component at different temperatures, prevent the components from deforming and being damaged due to the accumulation of internal stress, extend the service life of the split slider 3, and ensure the long-term stable operation of the tracking bracket.

[0043] In this embodiment, the covering angle of the arc-shaped limiting groove (311, 321) is 200°~270°, and the fitting gap with the support base (1) is 0.5~2mm.

[0044] This design, with its large wrap-around angle, effectively resists radial runout and lateral wind loads of the main beam, avoiding the risk of derailment in extreme weather. Furthermore, the precise fit clearance prevents jamming while ensuring positioning accuracy, and is also compatible with thermal expansion and contraction. This combined design results in a more uniform distribution of frictional stress and matches the transmission tolerances of the drive system, avoiding transmission lag or slippage issues.

[0045] The upper slider 31 includes a detachably connected upper slider body 312 and a mounting block 313. The arc-shaped limiting groove 311 on the outer side wall of the upper slider body 312 is slidably connected to the support seat 1, and the inner side wall of the mounting block 313 is pressed and fixedly connected to the main beam 2.

[0046] The upper slider body 312 is integrally connected to a connecting plate 314, and the mounting block 313 is provided with a connecting groove 315 that is adapted to the connecting plate 314.

[0047] The connecting plate 314 has a first connecting hole 316 and the mounting block 313 has a second connecting hole 317. When the connecting plate 314 is fully inserted into the connecting groove 315, the first connecting hole 316 and the second connecting hole 317 are coaxially aligned and fixedly connected by fasteners.

[0048] With this design, the mounting block 313 and the upper slider body 312 are detachable. During installation, the mounting block 313 is fixed first because its regular shape and small size make it easy to position. Then, it is connected to the upper slider body 312. This step-by-step operation reduces difficulty and improves efficiency. Furthermore, through the cooperation of the connecting plate 314 and the connecting groove 315, fine adjustments can be made to compensate for the previous installation deviations, reducing the requirements for installation accuracy and improving the success rate of installation.

[0049] Secondly, in case of malfunction, the damaged parts can be directly replaced. If there is a problem with the upper slider body 312 or the mounting block 313, they can be disassembled and replaced separately, saving time and labor costs.

[0050] Furthermore, the upper slider body 312 is responsible for sliding friction and can be made of wear-resistant materials such as high-hardness alloys or surface coatings, while the mounting block 313 is responsible for pressing and fixing with the main beam 2 and can be made of high-toughness materials to avoid the performance limitations caused by using a single material for the whole.

[0051] Finally, the modular structure reduces the difficulty of machining large components, and the standardized connection design improves production efficiency. Meanwhile, the modular mounting blocks can adapt to different main beam sizes or angles, expanding the equipment's applicability and supporting future functional upgrades such as adding sensors or buffer components.

[0052] In this embodiment, the connecting plate 314 and the connecting groove 315 are self-locking trapezoidal structures.

[0053] This design has several advantages. First, the trapezoidal cross-section dovetail groove structure has a self-centering function, which can automatically correct assembly deviations and resist lateral offset, ensuring precise alignment between the upper slider body and the mounting block. At the same time, its wedge effect generates additional clamping force after tightening, significantly improving vibration resistance and loosening resistance, making it particularly suitable for high-load or frequent-movement working conditions.

[0054] Secondly, the asymmetrical trapezoidal structure prevents reverse installation and reduces the risk of operational errors. The progressive guiding characteristics of the inclined plane allow for a certain tolerance to machining errors, making assembly smoother, while dispersing contact stress, reducing local wear, and extending the service life of parts.

[0055] Furthermore, the trapezoidal contact surface can evenly distribute the load, avoiding stress concentration, and can withstand greater radial forces and impacts compared to a rectangular cross-section. After wear, the gap can be compensated by adjusting the fasteners, reducing the frequency of replacement and balancing structural strength and economy.

[0056] The bottom of the support base 1 is welded with a support member 4, which is used to connect the column 5 of the photovoltaic bracket.

[0057] With this design, firstly, the support component 4 is welded to the bottom of the support base 1 and connected to the column 5 of the photovoltaic bracket. This not only provides an additional stable support point for the entire support base 1, thereby improving the wind and vibration resistance of the support base 1 and preventing displacement or tilting, but also effectively transfers the external forces such as the gravity and wind pressure of the photovoltaic panel to the column 5 and distributes them to the entire foundation structure of the photovoltaic bracket, reducing local stress in the support base 1 and further enhancing the stability of the support base 1.

[0058] Secondly, the support component 4 enhances the structural rigidity of the support base 1, thereby effectively resisting the torsional force generated when the main beam 2 rotates. It also works in conjunction with the column 5 to prevent the support base 1 from undergoing torsional deformation. This not only avoids deformation or damage caused by long-term torsional stress, but also ensures that the split slider 3 is always in the optimal working position, while reducing vibration or offset during rotation, ensuring the accuracy of photovoltaic bracket tracking, and ultimately optimizing power generation efficiency.

[0059] The support member 4 is a C-shaped steel structure. Multiple waist-shaped adjustment holes 41 are evenly provided along the height direction of the support member 4. The length direction of the waist-shaped adjustment holes 41 is perpendicular to the axis direction of the support member 4.

[0060] The support member 4 is connected to the column 5 by fasteners. The column 5 has multiple round holes 51 corresponding to the waist-shaped adjustment holes 41 along the height direction. The round holes (51) are arranged at equal intervals along the axial direction of the column (5).

[0061] This design allows for several advantages. First, the waist-shaped adjustment hole 41 aligns with the width of the support member 4, enabling the bolt to move horizontally within the hole. When the bolt is loosened, the support member 4 can slide left and right, facilitating easy adjustment of the horizontal position of the support base 1. This effectively addresses errors that occur during the installation of the tracking bracket or positional deviations caused by structural deformation. Second, the column 5 is equipped with multiple round holes 51, allowing the waist-shaped adjustment hole 41 of the support member 4 to be fixed at different heights. This precisely adjusts the vertical installation height of the support member 4 and the support base 1, meeting the diverse installation needs of different photovoltaic brackets and greatly improving installation flexibility and efficiency.

[0062] Example 2: The other structures are the same as in Example 1, except that: Figure 8-10 As shown, the support member 4 includes a fixing plate 42 welded to the bottom of the support base 1. The bottom of the fixing plate 42 is fixedly connected to an inverted U-shaped mounting bracket 43. Mounting hole groups 44 are symmetrically opened on both sides of the mounting bracket 43. The mounting hole group 44 includes a first limiting hole 441 and an arc-shaped hole 442.

[0063] The column 5 has symmetrical connecting hole groups on both sides. The connecting hole groups include two second limiting holes 52. One of the second limiting holes 52 is fixedly connected to the arc-shaped hole 442 by a fastener, and the other second limiting hole 52 is fixedly connected to the first limiting hole 441 by a fastener.

[0064] First, the arc-shaped hole 442 on the support 4 allows the support 4 to finely adjust the installation angle relative to the column 5, reducing the requirements for installation accuracy and improving installation efficiency. At the same time, the multiple connection hole groups 42 on the column 5 can meet the installation needs of different heights and adapt to diverse terrains and design requirements.

[0065] Secondly, the mounting holes on both sides of the wall are connected to the column 5 to form a multi-point connection, which evenly distributes the loads such as gravity and wind force of the photovoltaic panel, reduces local stress concentration, and the connection points work together to resist torsional and shear forces, enhancing the torsional and shear resistance.

[0066] Furthermore, the arc-shaped hole 442 can compensate for structural deformation and displacement caused by foundation settlement, thermal expansion and contraction, etc., to ensure normal operation of the system and extend its service life.

[0067] In the above embodiments, the fasteners are all bolt and nut assemblies.

[0068] This design, firstly, uses bolt and nut assemblies as fasteners, which can directly utilize mature industrial standard parts to ensure the reliability and consistency of connection strength. Moreover, the threaded locking structure can provide stable preload, and anti-loosening measures such as spring washers or thread sealant can effectively resist loosening caused by vibration, thus maintaining connection stability over the long term.

[0069] Secondly, bolted connections allow for precise control of the clamping force by adjusting the tightening torque, adapting to different working conditions. Disassembly does not require structural damage, facilitating quick replacement or maintenance of mounting blocks and significantly reducing maintenance time and costs.

[0070] Furthermore, bolts and nuts are universal components with low procurement costs and ample supply, and they do not require custom processing. Their specifications can be flexibly matched with the size of the connection hole, making them compatible with accessories from different manufacturers, thus improving the adaptability of the equipment and the resilience of the supply chain.

[0071] In addition to the above embodiments, the fastener may also be a pin connector or a snap-fit ​​connector.

[0072] The bolt and nut assemblies, pin connectors, and snap-fit ​​connectors all utilize mature, existing technologies and can be directly obtained through market procurement. Given that their structural design and working principles are already well-known to those skilled in the mechanical field, this article will not elaborate on their specific construction and operating mechanisms to simplify the content and focus on the core technical solutions.

[0073] In the above example, the split slider 3 is made of wear-resistant engineering plastic.

[0074] This design utilizes the excellent wear resistance, high hardness, and strength of the wear-resistant engineering plastic, enabling it to withstand high friction and wear, extending the slider's service life and reducing equipment failure and maintenance costs. Its good self-lubricating properties reduce the coefficient of friction and energy loss, resulting in smoother and quieter equipment operation. Its lightweight nature facilitates equipment installation, handling, and operation, while also reducing requirements for support structures. Strong corrosion resistance allows for use in harsh environments, enhancing equipment reliability. Good insulation properties ensure equipment safety. Flexible design allows for the manufacture of complex shapes and sizes to meet diverse equipment needs while reducing costs and increasing efficiency. Furthermore, it possesses shock absorption and noise reduction functions, absorbing vibration and impact and improving the working environment.

[0075] The wear-resistant engineering plastics used in the above embodiments are mature existing technologies, and their material properties, molding processes, and application principles are well known to those skilled in the art of materials engineering. To highlight the core innovation of this design and avoid repetition of technical content, their specific technical details will not be elaborated here.

[0076] In addition to this embodiment, the split slider can also be made of stainless steel, aluminum alloy, etc.

[0077] The opposing side walls of the upper slider 31 and the lower slider 32 form the clamping cavity of the main beam 2.

[0078] In the embodiments, the clamping cavity is a rectangular hole, a pentagonal hole, a hexagonal hole, a heptagonal hole, a circular hole, a D-shaped hole, etc.

[0079] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
