Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic power generation equipment, and particularly to a rotation structure of a flat single-axis tracking bracket. Background Technique

[0002] The photovoltaic bearing structure is a bearing structure used in photovoltaic modules. At present, with the continuous development of technology, a general monomer large single-axis photovoltaic bracket uses a long and thick rotating beam to carry a large number of photovoltaic modules. The long and thick rotating beam passes through several bearings, and several bearings are installed on several columns standing on the ground to ensure the stable operation of the rotating beam.

[0003] For example, Chinese Patent No. CN111628709B discloses a main beam and bearing assembly of a photovoltaic tracking bracket and a photovoltaic tracking bracket. The main beam and bearing assembly includes a support seat, a main beam, an upper bearing and a blocking member. The support seat is used to be installed on the column of the photovoltaic tracking bracket, and a through hole is provided on the support seat; the main beam is inserted into the through hole; the upper bearing is inserted into the through hole and is located in the gap between the main beam and the support seat. One end of the upper bearing is provided with a shoulder protruding from its upper surface, and the shoulder abuts against one end of the support seat. The other end of the upper bearing is provided with a groove; the blocking member is clamped with the groove, and the part protruding from the groove abuts against the other end of the support seat. In the present invention, both ends of the upper bearing are limited by the shoulder and the blocking member respectively, and there is no relative displacement space between the upper bearing and the support seat. Even if the main beam and the column have relative displacement, the upper bearing will not have relative displacement with the support seat, reducing potential safety hazards.

[0004] However, there are still many deficiencies in the above structure during use. First of all, the two ends of the upper bearing are limited by the shoulder and the blocking member. During installation, the positions of all components need to be accurately operated, and the installation accuracy requirements are high, increasing the installation difficulty.

[0005] Secondly, when maintaining or replacing the bearing, the process of removing and reinstalling the blocking member is complicated, special tools are required, and the reinstallation needs to ensure accuracy, otherwise the limiting effect will be affected.

[0006] Thirdly, to ensure the reliability of the limiting structure, high requirements are imposed on the material strength and wear resistance of related components, resulting in an increase in the procurement cost of raw materials. The complex structure also increases the processing cost of components and the overall manufacturing cost.

[0007] In addition, the two ends of the upper bearing are strictly limited, and the internal stress generated by the thermal expansion and contraction of each component at different temperatures cannot be relieved through the relative displacement of the upper bearing. Long-term accumulation may cause component deformation and damage, shortening the service life.

[0008] Finally, during the rotation of the main beam, due to the existence of the limit structure, certain frictional resistance will be increased. The additional frictional resistance affects the tracking accuracy and operating efficiency of the photovoltaic tracking bracket, and a greater driving force is required to achieve the rotation of the main beam. Summary of the Invention

[0009] The main technical problem to be solved by the present invention is to provide a single-axis tracking bracket rotation structure for flat surfaces, which has a simple structure, is convenient for installation, easy to maintain, low in manufacturing cost, easy to process, strong in environmental adaptability, accurate in tracking, and high in operating efficiency.

[0010] To solve the above technical problems, the present invention provides the following technical solutions: A single-axis tracking bracket rotation structure for flat surfaces includes a support base. The support base is a closed circular ring body, and its inner edge and outer edge are arranged concentrically, and the radial cross-section is circular. The main beam of the tracking bracket is coaxially inserted into the support base. A split slider is arranged in the radial gap between the main beam and the support base, and the split slider enables 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 side walls of the upper slider and the lower slider are respectively fixedly connected to the main beam, and arc-shaped limit grooves are respectively formed on the outer side walls. The inner wall of the arc-shaped limit groove wraps the outer peripheral surface of the support base to form a sliding fit structure. A support member for connecting the column of the tracking bracket is welded to the bottom of the support base.

[0011] The following is a further optimization of the above technical solution by the present invention: The upper slider includes a detachable upper slider body and a mounting block. The arc-shaped limit groove on the outer side wall of the upper slider body is slidably connected to the support base, and the inner side wall of the mounting block is fixedly connected to the main beam by extrusion.

[0012] Further optimization: A connecting plate is integrally connected to the upper slider body, and a connecting groove adapted to the connecting plate is formed on the mounting block.

[0013] Further optimization: A first connection hole is formed on the connecting plate, and a second connection hole is formed on the mounting block. When the connecting plate is completely inserted into the connecting groove, the first connection hole and the second connection hole are coaxially aligned and fixedly connected by a fastener.

[0014] Further optimization: The support member is a C-shaped steel structure, and a plurality of waist-shaped adjustment holes are uniformly formed in the support member along its height direction. The length direction of the waist-shaped adjustment holes is perpendicular to the axis direction of the support member.

[0015] Further optimization: The support member is connected to the column by a fastener. A plurality of round holes corresponding to the waist-shaped adjustment holes are formed on the column along the height direction, and the round holes are arranged at equal intervals along the axial direction of the column.

[0016] Further optimization: The support member alternatively includes a fixing plate welded to the bottom of the support base. The bottom of the fixing plate is fixedly connected with a mounting bracket in an inverted U-shaped structure. Mounting hole groups are symmetrically formed on both side walls of the mounting bracket. The mounting hole group includes a first limiting hole and an arc-shaped hole.

[0017] Further optimization: Connecting hole groups are symmetrically formed on both sides of the column. The connecting hole group includes two second limiting holes. One of the second limiting holes is connected to the arc-shaped hole through a fastener, and the other second limiting hole is connected to the first limiting hole through a fastener.

[0018] In the present invention, the coaxial structure formed by the support base of the closed circular ring body and the main beam, in combination with the design of the split slider, realizes stable support in a full 360-degree circumferential direction. This structure can evenly distribute the load, significantly improving the wind load resistance and deformation resistance of the bracket, and is particularly suitable for stable operation under harsh weather conditions.

[0019] In the present invention, the arc-shaped limiting grooves of the upper slider and the lower slider form a covering sliding fit with the support base. This structure not only enhances the rotational stability but also effectively prevents the main beam from shifting or shaking during rotation. At the same time, the symmetrical arrangement of the double sliders also realizes the automatic centering function, greatly reducing the requirements for installation accuracy and making the installation and debugging more convenient.

[0020] In the present invention, the split slider structure allows for the replacement of worn parts individually without overall disassembly, significantly reducing the maintenance cost and time. Therefore, this rotating structure is particularly suitable for long-term use in harsh environments such as deserts and coastal areas.

[0021] In the present invention, the split slider has a relative displacement space, which can effectively relieve the internal stress generated 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 manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Embodiment 1: As Figures 1-7As shown, a flat single-axis tracking bracket rotation structure includes a support seat 1, which is a closed circular ring body, whose inner edge and outer edge are arranged in concentric circles, and the radial cross-section is a circle; the main beam 2 of the tracking bracket is coaxially inserted in the support seat 1, and a split slider 3 is arranged in the radial gap between the main beam 2 and the support seat 1, and the split slider 3 enables the main beam 2 to rotate around the axis of the support seat 1; the split slider 3 includes an upper slider 31 and a lower slider 32, the inner side walls of the upper slider 31 and the lower slider 32 are respectively fixedly connected to the main beam 2, and arc-shaped limit grooves 311 and 321 are respectively opened on the outer side walls, and the inner walls of the arc-shaped limit grooves 311 and 321 cover the outer peripheral surface of the support seat 1 to form a sliding fit structure.

[0028] With this design, firstly, the coaxial structure formed by the support seat 1 of the closed circular ring and the main beam 2, combined with the design of the split slider 3, achieves 360-degree full-circle stable support. This structure can evenly distribute the load, significantly improves the support's ability to resist wind loads and deformation, and is particularly suitable for maintaining stable operation under severe weather conditions.

[0029] Secondly, the arc-shaped limit grooves 311 and 321 of the upper slider 31 and the lower slider 32 form an enveloping sliding fit with the support seat 1. This structure not only enhances the rotation stability, but also effectively prevents the main beam 2 from shifting or shaking during rotation; at the same time, the symmetrical arrangement of the double sliders also realizes the automatic centering function, which greatly reduces the installation accuracy requirements and makes installation and debugging easier.

[0030] Thirdly, the split slider 3 adopts a split structure, which allows the worn parts to be replaced individually without the need for overall disassembly, greatly reducing maintenance costs and time, making the rotating structure particularly suitable for long-term use in harsh environments such as deserts and coastal areas.

[0031] Finally, the relative displacement space of the split slider 3 can effectively alleviate the internal stress caused by thermal expansion and contraction of various components at different temperatures, prevent the components from being deformed and damaged due to the accumulation of internal stress, extend the service life of the split slider 3, and ensure the long-term and stable operation of the tracking bracket.

[0032] In this embodiment, the covering angle of the arc-shaped limiting groove (311, 321) is 200° to 270°, and the matching clearance with the support seat (1) is 0.5 to 2 mm.

[0033] With this design, the large wrap angle can effectively resist the radial runout and lateral wind load of the main beam 2, avoiding the risk of derailment in extreme weather; and the precise matching clearance can prevent jamming and ensure positioning accuracy, while being compatible with thermal expansion and contraction. This combined design makes the friction stress distribution more uniform and can match the transmission tolerance of the drive system to avoid transmission lag or slippage problems.

[0034] The upper slider 31 includes an upper slider body 312 and a mounting block 313 which are detachably connected. The arc-shaped limiting groove 311 on the outer side wall of the upper slider body 312 is slidably connected with the support base 1, and the inner side wall of the mounting block 313 is fixedly connected with the main beam 2 by extrusion.

[0035] A connecting plate 314 is integrally connected to the upper slider body 312, and a connecting groove 315 adapted to the connecting plate 314 is formed on the mounting block 313.

[0036] The connecting plate 314 is provided with a first connecting hole 316, and the mounting block 313 is provided with a second connecting hole 317. When the connecting plate 314 is completely 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.

[0037] With this design, first, the mounting block 313 and the upper slider body 312 are detachable. During installation, the mounting block 313 is fixed first. Because of its regular shape and small size, it is convenient to position. Then the upper slider body 312 is docked. The step-by-step operation reduces the difficulty and improves the efficiency. Moreover, through the cooperation of the connecting plate 314 and the connecting groove 315, the pre-installation deviation can be finely adjusted to make up for it, reducing the requirement for installation accuracy and improving the installation success rate.

[0038] Secondly, when a failure occurs, the damaged parts can be directly replaced. Whether there is a problem with the upper slider body 312 or the mounting block 313, they can be separately disassembled and replaced, saving time and labor costs.

[0039] Thirdly, the upper slider body 312 is responsible for sliding friction, and wear-resistant materials such as high-hardness alloys or surface coatings can be used. While the mounting block 313 is responsible for extrusion fixation with the main beam 2, high-toughness materials can be used to avoid the performance limitations brought by using a single material as a whole.

[0040] Finally, the split structure reduces the processing difficulty of large parts, and the standardized connection design improves the production efficiency. At the same time, the modular mounting block 313 can be adapted to different main beam sizes or angles, expanding the applicable range of the equipment, and supporting later function upgrades such as installing sensors or buffer components.

[0041] In this embodiment, the connecting plate 314 and the connecting groove 315 are of a self-locking trapezoidal structure.

[0042] With this design, first, the inclined plane fit of the trapezoidal cross-section dovetail groove structure has a self-centering function, which can automatically correct the assembly deviation and resist lateral offset, ensuring the precise alignment of the upper slider body 312 and the mounting block 313. At the same time, its wedge effect generates an additional pressing force after fastening, significantly improving the anti-vibration and anti-loosening capabilities, which is especially suitable for working conditions with high loads or frequent movements.

[0043] Secondly, the asymmetric trapezoidal structure can prevent reverse installation and reduce the risk of operation errors. The progressive guiding characteristic of the inclined plane allows a certain tolerance for machining errors, making the assembly smoother. At the same time, it disperses the contact stress, reduces local wear, and extends the service life of the parts.

[0044] Thirdly, the trapezoidal contact surface can evenly distribute the load and avoid stress concentration. Compared with the rectangular cross-section, it can withstand greater radial force and impact. After wear, the clearance can be compensated by adjusting the fasteners, reducing the replacement frequency, and taking into account both structural strength and economy.

[0045] A support member 4 is welded to the bottom of the support base 1, and the support member 4 is used to connect the column 5 of the photovoltaic bracket.

[0046] With such a design, firstly, the support member 4 is welded to the bottom of the support base 1 and connected to the column 5 of the photovoltaic bracket, which not only provides an additional stable support point for the entire support base 1, thereby improving the wind resistance and vibration resistance of the support base 1 and preventing displacement or tilt; but also effectively transfers the external forces such as the gravity of the photovoltaic panel and the wind pressure to the column 5 and disperses them to the basic structure of the entire photovoltaic bracket, reducing the local stress of the support base 1 and further enhancing the stability of the support base 1.

[0047] Secondly, the support member 4 enhances the structural rigidity of the support base 1, so that it can effectively resist the torsional force generated when the main beam 2 rotates. And it works together with the column 5 to prevent the support base 1 from undergoing torsional deformation. Furthermore, it not only avoids deformation or damage caused by long-term torsional stress, but also ensures that the split slider 3 is always in the best working position, while reducing vibration or offset during rotation, ensuring the accuracy of the photovoltaic bracket tracking, and ultimately optimizing the power generation efficiency.

[0048] The support member 4 is of a C-shaped steel structure, and a plurality of waist-shaped adjustment holes 41 are evenly arranged along the height direction of the support member 4, and the length direction of the waist-shaped adjustment holes 41 is perpendicular to the axis direction of the support member 4.

[0049] The support member 4 is connected to the column 5 through fasteners. A plurality of round holes 51 corresponding to the waist-shaped adjustment holes 41 are arranged along the height direction on the column 5, and the round holes 51 are arranged at equal intervals along the axial direction of the column 5.

[0050] With such a design, firstly, the waist-shaped adjustment holes 41 are in the same width direction as the support member 4, and the bolt can move horizontally in the waist-shaped adjustment holes 41. When the bolt is loosened, the support member 4 can slide left and right, and the horizontal position of the support base 1 can be adjusted conveniently, effectively dealing with the errors that occur during the installation of the tracking bracket or the position deviation caused by structural deformation; at the same time, the column 5 is provided with a plurality of round holes 51, and the waist-shaped adjustment holes 41 of the support member 4 can be fixed corresponding to the round holes 51 at different heights, accurately adjusting the vertical installation height of the support member 4 and the support base 1, meeting the diverse installation requirements of different photovoltaic brackets, and greatly improving the installation flexibility and efficiency.

[0051] Example 2: Other structures are the same as those in Example 1, except that: as Figures 8-10 shown, the support member 4 alternatively includes a fixing plate 42 welded to the bottom of the support base 1. The bottom of the fixing plate 42 is fixedly connected with an inverted U-shaped mounting frame 43. Mounting hole groups 44 are symmetrically formed on both side walls of the mounting frame 43. The mounting hole group 44 includes a first limiting hole 441 and an arc-shaped hole 442.

[0052] Connecting hole groups are symmetrically formed on both sides of the column 5. The connecting hole group includes two second limiting holes 52. One of the second limiting holes 52 is fixedly connected with the arc-shaped hole 442 through a fastener, and the other second limiting hole 52 is fixedly connected with the first limiting hole 441 through a fastener.

[0053] First, the arc-shaped hole 442 on the support member 4 enables the support member 4 to finely adjust the installation angle relative to the column 5, reducing the requirement for installation accuracy, improving the installation efficiency. At the same time, multiple connecting hole groups on the column 5 can meet the installation requirements at different heights, adapting to diverse terrains and design requirements.

[0054] Second, the mounting hole groups 44 on both side walls are connected to the column 5 to form multiple-point connections, evenly dispersing loads such as the gravity and wind force of the photovoltaic panel, reducing local stress concentration, and each connection point collaborates to resist torsional force and shear force, enhancing the torsional and shear resistance capabilities.

[0055] Third, the arc-shaped hole 442 can compensate for structural deformation and displacement caused by factors such as foundation settlement, thermal expansion and contraction, etc., ensuring the normal operation of the system and extending the service life.

[0056] In the above embodiments, the fasteners all adopt bolt-nut assemblies.

[0057] With such a design, first, using bolt-nut assemblies as fasteners can directly utilize mature industrial standard parts, ensuring the reliability and consistency of the connection strength. Moreover, the threaded locking structure can provide a stable pre-tightening force, and through anti-loosening measures such as spring washers or thread adhesives, it can effectively resist loosening caused by vibration, maintaining the connection stability for a long time.

[0058] Second, bolt connections allow precise control of the clamping force by adjusting the tightening torque, adapting to different working conditions. During disassembly, the structure does not need to be damaged, facilitating the rapid replacement or maintenance of the mounting block 313, greatly reducing the maintenance time and cost.

[0059] Third, bolts and nuts are common parts with low procurement costs and sufficient supply, and no custom processing is required. Their specifications can be flexibly matched with the connection hole sizes, compatible with accessories from different manufacturers, improving the adaptability of the equipment and the flexibility of the supply chain.

[0060] In addition to the above embodiments, the fasteners can also adopt pin connectors or snap connectors.

[0061] The bolt - nut assembly, pin connector, and snap - fastener connector are all mature existing - technology products and can be directly obtained through market procurement. Given that their structural designs and working principles are well - known to those skilled in the mechanical field, to streamline the content and focus on the core technical solutions, the specific structures and operating mechanisms are not elaborated in detail in this article.

[0062] In the above example, the split slider 3 is made of wear - resistant engineering plastic.

[0063] With such a design, wear - resistant engineering plastic has good wear resistance, high hardness and strength, can withstand large frictional forces and wear, extend the service life of the slider, and reduce equipment failures and maintenance costs; it has good self - lubricity, reduces the friction coefficient and energy loss, making the equipment run more smoothly and quietly; it is light in weight, facilitating equipment installation, handling, and operation, and also reducing the requirements for the support structure; it has strong corrosion resistance, can be used in harsh environments, and improves equipment reliability; it has good insulation performance, ensuring equipment safety; it has flexible design, can be made into complex shapes and sizes, meeting the needs of different equipment, reducing costs, and improving efficiency; at the same time, it has shock - absorption and noise - reduction functions, can absorb vibration shocks, and improve the working environment.

[0064] The wear - resistant engineering plastic used in the above - mentioned embodiment belongs to mature existing technology, and its material properties, molding process, and application principles are well - known to those skilled in the field of materials engineering. To highlight the core innovation points of this design and avoid repetition of technical content, the specific technical details are not elaborated here.

[0065] In addition to this embodiment, the split slider 3 can also be made of stainless steel, aluminum alloy, etc.

[0066] The opposite side walls of the upper slider 31 and the lower slider 32 form a clamping cavity for the main beam 2.

[0067] In the embodiment, the clamping cavity is a rectangular hole, pentagonal hole, hexagonal hole, heptagonal hole, circular hole, D - shaped hole, etc.

[0068] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present invention.
