Description

Technical Field

[0001] The present invention is a highly adaptable driving device for bracket rotation, belonging to the technical field of photovoltaic brackets. Background Art

[0002] By intelligently adjusting the angle of photovoltaic modules to maximize the reception of direct sunlight, light loss can be reduced, thereby significantly improving the power generation efficiency. Currently, the angle of photovoltaic modules can be adjusted for installation. First, it is necessary to rotate the bracket for installing the angle of the photovoltaic module, and then control the rotation angle of the bracket through a corresponding driving device to adjust the photovoltaic module to the side facing the sun in real time.

[0003] Most of the traditional driving devices for adjusting the angle of photovoltaic modules adopt worm and worm gear driving equipment. The installation position of this type of driving is fixed, and sometimes it is inconvenient to install due to special environmental factors, resulting in a reduction in driving efficiency; when a failure occurs, since the installation position is generally located at a high place, there are safety hazards during maintenance and the maintenance cost is high. For this reason, the existing driving devices for adjusting the angle of photovoltaic modules have been improved to: install a bearing member on the installation bracket of the photovoltaic module, and then cooperate with a driving power source through a steel wire rope wound around the bearing member to control the rotation amount of the bearing member, and then control the rotation angle of the installation bracket of the photovoltaic module. Due to the certain elongation rate of the steel wire rope, the problem of insufficient tension will occur in the cooperation between the steel wire rope and the bearing member during subsequent use, which is very troublesome.

[0004] Therefore, the research purpose of the present invention is to design a highly adaptable driving device for bracket rotation that can effectively improve the installation convenience and connection stability when the steel wire rope cooperates with the bearing member, and can overcome the problem of insufficient tension caused by the elongation of the steel wire rope. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a highly adaptable driving device for bracket rotation to solve the problems of the existing technology.

[0006] In order to achieve the above purpose, the present invention is realized through the following technical solutions:

[0007] A highly adaptable driving device for bracket rotation, comprising:

[0008] A bearing member that rotates;

[0009] A first pulley assembly fixedly arranged near the bearing member, and a second pulley assembly fixedly arranged away from the bearing member;

[0010] And a driving assembly for driving the bearing member to rotate, the driving assembly comprising:

[0011] One or more first flexible traction components wound around the carrier, and one or more second flexible traction components wound around the outside of the second pulley assembly. The first flexible traction component is guidingly arranged inside the first pulley assembly;

[0012] A drive motor connecting one end of the first flexible traction component and one end of the second flexible traction component, and a rigid connection component connecting the other end of the first flexible traction component and the other end of the second flexible traction component;

[0013] Through the cooperation of the drive motor with the first flexible traction component, the second flexible traction component, and the rigid connection component, the carrier is synchronously driven to adjust the angle clockwise / counterclockwise.

[0014] As a further improvement, the number of both the first flexible traction component and the second flexible traction component is two. The first flexible traction component uses a first steel wire rope with a diameter range of 8 - 14 mm, and the second flexible traction component uses a second steel wire rope with a diameter range of 8 - 14 mm.

[0015] As a further improvement, the drive motor includes a fixedly arranged mounting shell, an externally threaded rod rotatably mounted inside the mounting shell, and a motor for driving the externally threaded rod to rotate;

[0016] Two pull rods penetrating through the mounting shell in parallel, and internally threaded lock plates vertically mounted on the two pull rods. The internally threaded lock plates are threadedly connected to the externally threaded rod;

[0017] By driving the externally threaded rod to rotate forward / backward by the motor, the internally threaded lock plates are driven to drive the pull rods to move up / down.

[0018] As a further improvement, corresponding connecting plates are horizontally mounted between the ends of the two pull rods respectively. The first flexible traction component and the second flexible traction component are symmetrically mounted to both sides of the middle of the corresponding connecting plate through corresponding connecting rods.

[0019] As a further improvement, both the first pulley assembly and the second pulley assembly include two symmetrically arranged pulleys and a fixing frame for fixing the two pulleys. The first flexible traction component passes through between the two pulleys of the first pulley assembly, and the second flexible traction component is wound around the outside of the two pulleys of the second pulley assembly.

[0020] As a further improvement, the axial distance between the two pulleys in the same group is less than the diameter of the carrier.

[0021] As a further improvement, the first flexible traction assembly includes a first steel wire rope that fits around the outer side of the carrier. The two ends of the first steel wire rope are bent inward, and the ends are fixedly locked to the rope body through a locking ring to form a first connection ring and a second connection ring. The first connection ring is connected to the rigid connection assembly, and the second connection ring is connected to the drive motor.

[0022] As a further improvement, the second flexible traction assembly includes a second steel wire rope that fits around the outer side of the carrier. The two ends of the two second steel wire ropes are bent inward, and the ends are fixedly locked to the rope body through a locking ring to form a third connection ring and a fourth connection ring. The third connection ring is connected to the rigid connection assembly, and the fourth connection ring is connected to the drive motor.

[0023] As a further improvement, the rigid connection assembly includes a first connecting rod that connects the first steel wire rope and the second steel wire rope. The two ends of the first connecting rod are bent inward to form a first hook body and a second hook body. The first hook body is connected to the first connection ring, and the second hook body is connected to the third connection ring.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) Through the cooperation of the drive motor and the rigid connection assembly, especially the intervention of the rigid connection assembly, the present invention can significantly shorten the length of the first flexible traction assembly and the second flexible traction assembly, and effectively solve the elongation problem existing in the application of the first flexible traction assembly and the second flexible traction assembly without affecting the angular drive, thereby ensuring the overall operation and maintenance stability and reliability of the present invention.

[0026] 2) In order to ensure that the steel wire rope of the driving device can smoothly drive the photovoltaic module mounting bracket to rotate and does not generate a fracture risk in harsh environments, for example, to withstand an eight-level wind and snow environment, the tensile strength needs to reach 1770 Mpa, and its specification requirement is above 20 mm. When using a steel wire rope above 20 mm for fixation in cooperation with the carrier, due to the excessive rigidity of the steel wire rope, it is not only not conducive to installation but also not easy to form a stable fixation with the carrier.

[0027] Therefore, the present invention replaces the traditional large-diameter single-group steel wire rope with small-diameter double first flexible traction assemblies and second flexible traction assemblies. While maintaining the same connection strength, it significantly reduces the rigidity of a single first flexible traction assembly and second flexible traction assembly, thereby enhancing its flexibility to improve the installation convenience of the present invention and the connection stability with the carrier.

[0028] 3) By increasing the number of wire ropes, although the problem of insufficient flexibility existing in the use of a single large-diameter wire rope is solved, however, once the elongation rates of different wire ropes are significantly different due to construction and other factors, the situation of uneven force will occur. In this way, most of the force will be concentrated on the wire rope with a smaller elongation rate, which will further lead to the risk of wire rope breakage in a harsh environment. For this reason, the present invention further horizontally installs connecting plates between the ends of the two pull rods of the driving machine, and symmetrically installs the first flexible traction assembly and the second flexible traction assembly on both sides of the middle of the connecting plate through corresponding connecting rods. In this way, when the elongation rates of different wire ropes are different, the angular deflection of the connecting plate can be used for adaptive compensation, so that the forces on different wire ropes are maintained in a reasonable balance state, so as to ensure that the wire ropes of the present invention do not break in a harsh environment, thereby greatly improving the practical effect of the present invention.

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0037] Due to the uneven driving force of the traditional angle adjustment device, the traditional single-side driving method is prone to efficiency loss and insufficient accuracy in force distribution. Especially when the equipment structure is large, in harsh weather such as strong wind and heavy snow, the impact of the wind on the equipment is usually asymmetric, resulting in the equipment tilting or shaking during the adjustment process, affecting the adjustment accuracy of the photovoltaic panel and the effect of receiving sunlight. Therefore, a highly adaptable driving device for bracket rotation is designed to solve this problem.

[0038] Referring to Figures 1-4 as shown, a highly adaptable driving device for bracket rotation includes:

[0039] a rotatably arranged carrier 1;

[0040] a first pulley assembly 4 fixedly arranged near the carrier 1 and a second pulley assembly 5 fixedly arranged away from the carrier 1;

[0041] and a driving assembly for driving the carrier 1 to rotate, the driving assembly includes:

[0042] One or more first flexible traction components 2 wound around the carrier 1, one or more second flexible traction components 3 wound around the outside of the second pulley assembly 5, and the first flexible traction component 2 is guidingly arranged inside the first pulley assembly 4;

[0043] A drive motor 6 connecting one end of the first flexible traction component 2 and one end of the second flexible traction component 3, and a rigid connection component 7 connecting the other end of the first flexible traction component 2 and the other end of the second flexible traction component 3;

[0044] Through the cooperation of the drive motor 6 with the two first flexible traction components 2, the second flexible traction component 3, and the rigid connection component 7, the carrier 1 is synchronously driven to adjust the angle clockwise or counterclockwise.

[0045] Wherein, through the constraint of the first flexible traction component 2 by the first pulley assembly 4, the adhesion between the first flexible traction component 2 and the carrier 1 is increased.

[0046] By installing a photovoltaic support such as a photovoltaic panel or a heliostat on the carrier 1. The carrier 1 is designed in the shape of a rotatably arranged disc, and its edge is ensured to be tightly combined with the photovoltaic support through a connecting member. Its fixed connection method is diverse, and it can be fixedly connected by bolts or other fittings, or by other methods such as welding.

[0047] The first pulley assembly 4 is fixed at a position close to the carrier 1, and the second pulley assembly 5 is fixed at a position far from the carrier 1. This can ensure the operating space of the flexible traction component and the control of the movement direction.

[0048] At the same time, two symmetric first flexible traction components 2 are wound around the carrier 1 and are slidably installed through the first pulley assembly 4. The second flexible traction component 3 is symmetrically and slidably arranged outside the second pulley assembly 5. The two are connected by a rigid connection component 7 and a drive motor 6 to form a stable drive structure. Among them, an arc-shaped groove is provided on the carrier 1, and the arc-shaped groove cooperates with the first steel wire rope 21.

[0049] When the angle of the photovoltaic panel needs to be adjusted, the drive motor 6 is started. The drive motor 6 synchronously controls the first flexible traction component 2 and the second flexible traction component 3 to achieve the clockwise or counterclockwise angle adjustment of the carrier 1.

[0050] By designing two symmetric first flexible traction components 2 and second flexible traction components 3, it is ensured that the rotational force of the carrier 1 is always evenly distributed, and a stable operating state can be maintained, avoiding tilting or jitter.

[0051] The cooperation between the driving machine 6 and the two first flexible traction components 2, the second flexible traction component 3 and the rigid connection component 7 can synchronously adjust the angle of the bearing member 1, ensure that the photovoltaic panel always faces the best position of the sun, and improve the power generation efficiency of the photovoltaic panel.

[0052] Due to the cooperation of the first flexible traction component 2, the second flexible traction component 3, the rigid connection component 7 and the bearing member 1, it can adapt to various harsh weather conditions (such as strong wind and heavy snow), and still maintain the adjustment accuracy under the condition of asymmetric external impact force.

[0053] Traditional single-sided drive is prone to force imbalance due to uneven driving force, while this device adopts a symmetric double-sided drive method to ensure driving force balance, effectively prevent tilting and jitter, and improve the accuracy and efficiency of adjustment. This device can cope with asymmetric external impacts such as wind force or snow force in harsh weather, so that the photovoltaic panel can still operate stably under strong wind or heavy snow conditions. Thanks to the synchronous action of the symmetric first flexible traction component 2, the second flexible traction component 3 and the rigid connection component 7, the angle adjustment accuracy of the bearing member 1 is greatly improved, which helps to improve the overall efficiency of the photovoltaic system. This device can adapt to different sizes of equipment and a variety of harsh environments, has stronger versatility and reliability, and meets the high-precision angle adjustment requirements of photovoltaic panels in different scenarios.

[0054] Through the cooperation of the first flexible traction component 2, the second flexible traction component 3 and the rigid connection component 7, the driving machine 6 can realize synchronous control of the bearing member 1, so as to ensure that the photovoltaic support can accurately and smoothly adjust the angle. Through the design of the pulley assembly and the flexible traction component, the stability of the entire photovoltaic support in strong wind weather can be enhanced, and the destructive impact of wind force on the equipment can be reduced.

[0055] Among them, the first pulley assembly 4 and the second pulley assembly 5 are both fixedly installed on the positioning member.

[0056] The first pulley assembly 4 and the second pulley assembly 5 both include two symmetrically arranged pulleys 41 and a fixing frame 42 for fixing the two pulleys 41. The first flexible traction component 2 passes through between the two pulleys 41 of the first pulley assembly 4, and the second flexible traction component 3 is wound around the outside of the two pulleys 41 of the second pulley assembly 5.

[0057] Among them, the positioning member can be other fixed support bodies such as a wall, a fixing frame, a fixing column, etc.

[0058] In traditional single-sided drive methods, the force distribution often concentrates on one side, making it easy for the equipment to be unevenly stressed. Especially when the equipment is large or subject to external impacts, single-sided drive cannot effectively cope. By symmetrically arranging the first pulley assembly 4 and the second pulley assembly 5, and allowing the flexible traction assembly to surround or pass through the pulley 41, the force on the entire system during driving can be made more uniform, avoiding tilting and instability.

[0059] The design of the pulley group can significantly reduce the friction and resistance generated during traction due to direct contact. The pulley 41 can provide a guiding and supporting function for the flexible traction assembly, enabling the traction force to be smoothly transmitted. This design of reducing friction and optimizing force transmission is to improve the efficiency of the drive system and reduce energy loss.

[0060] Both the first pulley assembly 4 and the second pulley assembly 5 are fixedly installed on the positioning member. The positioning member, such as a wall, a fixing bracket 42, or a fixing column, provides a stable foundation for the entire system. The purpose of this is to prevent the pulley group or the carrier 1 from moving or deforming due to external forces or its own weight during the adjustment process, thereby ensuring the accuracy and safety of the adjustment process.

[0061] The symmetric pulley group design ensures the force balance on both sides of the traction assembly, thus achieving the smooth operation of the system. During the adjustment process at any angle, the pulley group will disperse and equalize the force on the carrier 1. Such a design helps to avoid phenomena such as shaking, jittering, or tilting of the equipment during the adjustment process.

[0062] The symmetric arrangement of the pulley group combined with the flexible selection of the positioning member enables this design to adapt to various installation environments, such as being installed on a wall or a fixing column. It increases the adaptability of the system, allowing it to be used in multiple scenarios and meeting the requirements of different equipment structures.

[0063] Due to the good guiding property provided by the pulley group, the flexible traction assembly will not deviate from the designed trajectory when running on the pulley 41, which effectively improves the adjustment accuracy. Especially when facing large-sized photovoltaic equipment, precise angle adjustment is crucial for enhancing the overall efficiency of the photovoltaic system.

[0064] When the equipment is used in harsh weather such as strong winds and heavy snow, the external impact forces are usually asymmetric. Through this design of symmetrically arranged pulley groups and flexible traction assemblies, the equipment can better resist these asymmetric interferences, ensuring the stability and safety of the system.

[0065] To ensure the best balance among the traction force distribution, equipment stability, adjustment accuracy, and adaptability, the axial distance between the two pulleys 41 in the same group is less than the diameter of the carrier 1.

[0066] Among them, the ratio of the axle spacing of the pulleys 41 of the first pulley assembly 4 to the diameter of the load-bearing member 1 is 1 to 2:3, and no specific constraint is imposed on the second pulley assembly 5.

[0067] Since the specific ratio between the axle spacing of the pulleys 41 of the first pulley assembly 4 and the diameter of the load-bearing member 1 can optimize the distribution of the traction force on the load-bearing member 1. A smaller axle spacing of the pulleys 41 (less than the diameter of the load-bearing member 1) can ensure that the force exerted by the traction assembly on the load-bearing member 1 during driving is more concentrated and evenly distributed in the central area of the load-bearing member 1. This helps to avoid the situation of the load-bearing member 1 being distorted, bent or unevenly stressed during the adjustment process.

[0068] If the ratio of the axle spacing of the pulleys 41 to the diameter of the load-bearing member 1 is inappropriate, an excessive spacing will cause the traction force to act on the edge of the load-bearing member 1, increasing the risk of its bending or instability.

[0069] When the axle spacing of the pulleys 41 is too small, the force exerted by the traction assembly on the load-bearing member 1 will be more concentrated in the middle position. This force concentration will cause the edge part of the load-bearing member 1 to lack sufficient support, increasing the stress in the middle part of the load-bearing member 1, and will lead to the risk of the load-bearing member 1 being bent, deformed or even damaged.

[0070] Too small a spacing of the pulleys 41 will make the load-bearing member 1 prone to instability during the angle adjustment process. The concentrated action of the force will cause the device to be more prone to jitter or irregular movement during rotation, especially in bad weather (such as strong wind or heavy snow), and it is more vulnerable to the influence of asymmetric impacts, reducing the adjustment accuracy of the device. Too narrow an axle spacing of the pulleys 41 will cause the angle between the flexible traction assembly between the pulleys 41 to become steeper, increasing the friction between the pulleys 41 and the traction assembly. The increase in friction will not only reduce the driving efficiency, but also accelerate the wear of the pulleys 41 and the traction assembly, shortening the service life of the device.

[0071] When the spacing of the pulleys 41 is too small, the movement path of the traction assembly is restricted, which will cause the angle adjustment range to become smaller and unable to meet the device's demand for large-angle rotation, thus affecting the light-facing efficiency of the photovoltaic panel.

[0072] When the axle spacing of the pulleys 41 is too large, the force of the traction assembly acts on both ends or the edge of the load-bearing member 1, resulting in an overly wide dispersion range of the force. Such a force distribution makes the middle part of the load-bearing member 1 lack sufficient support, thus increasing the stress burden in the central part, resulting in uneven stress in the middle area during adjustment and even causing distortion or deformation.

[0073] An excessively large spacing between the pulleys 41 makes the transmission path of the traction force longer, increasing the tendency of the load-bearing member 1 to wobble or vibrate during the force application process. Such a situation is particularly likely to occur in large-sized equipment, making the adjustment process less stable and affecting the angular accuracy of the photovoltaic panel. A larger spacing between the pulleys 41 means that it is more difficult to control the precise angular change when the traction force acts, because the force is prone to shift or disperse during the transmission process, resulting in inaccurate angle adjustment. This situation will have a negative impact on the efficiency of the photovoltaic panel in capturing sunlight.

[0074] An excessively large axial spacing of the pulleys 41 requires more space for installation and operation, which will lead to an increase in the overall size of the equipment, increasing the complexity and cost of installation and maintenance. Especially in scenarios with limited space or compact installation of the equipment, it will cause inconvenience.

[0075] By designing the axial spacing of the pulleys 41 to be less than the diameter of the load-bearing member 1 and within the range of 1 to 2:3, it can be ensured that the force exerted by the traction assembly on the load-bearing member 1 is not concentrated on one side or the edge, but is evenly distributed over the entire load-bearing member 1. This can avoid the occurrence of unbalanced torque during rotation, reduce jitter and tilt, and ensure the robustness of the equipment.

[0076] Ensure that the pulley set and the load-bearing member 1 form a reasonable lever structure, and the traction force is smoothly transmitted to the load-bearing member 1 through the pulley 41 system, making the angle adjustment more delicate and smoother. For the angle adjustment of the photovoltaic panel, this precision can significantly improve the solar energy capture efficiency of the photovoltaic system, thereby improving the overall power generation efficiency.

[0077] Enable the system to adapt to photovoltaic brackets of different sizes. Whether it is a large-sized photovoltaic panel or a small heliostat, by adjusting the ratio of the axial spacing of the pulleys 41 to the diameter of the load-bearing member 1, it can ensure the best performance of the driving device under different conditions. This provides guarantee for the versatility and customization of the equipment in different application scenarios.

[0078] In order to ensure the uniform transmission of force, improve the stability and safety of the system, and at the same time ensure the reliability and efficiency of the traction device during the flexible traction process. The first flexible traction assembly 2 includes a first steel wire rope 21 that fits around the outer side surface of the load-bearing member 1. The two ends of the first steel wire rope 21 are bent inward, and the ends are fixedly locked to its rope body through a locking ring, forming a first connection ring 22 and a second connection ring 23. The first connection ring 22 is connected to the rigid connection assembly 7, and the second connection ring 23 is connected to the drive machine 6.

[0079] Among them, the locking ring can be a conventional locking structure such as a metal ring, sleeve, etc., mainly used to fixedly tie the bent end of the steel wire rope to the steel wire rope.

[0080] The second flexible traction assembly 3 includes a second steel wire rope 31 that fits around the outer side of the carrier 1. The two ends of the second steel wire ropes 31 are bent inward, and the ends are fixedly locked to the rope body through a locking ring to form a third connection ring 32 and a fourth connection ring 33. The third connection ring 32 is connected to the rigid connection assembly 7, and the fourth connection ring 33 is connected to the drive motor 6.

[0081] Both the first and second flexible traction assemblies 3 use steel wire ropes to fit around the outer side of the carrier 1. The main purpose is to ensure a tight fit between the steel wire rope and the carrier 1, forming a stable traction structure. Through the surrounding design, the traction force of the steel wire rope can act evenly on the outer surface of the carrier 1, rather than concentrating on a single point, avoiding damage or deformation caused by excessive local stress.

[0082] By bending and locking the two ends of the steel wire rope to form connection rings (the first, second, third, and fourth connection rings 33), the fixation of both ends of the steel wire rope can be ensured to be more reliable. The loop structure formed by bending and locking on its own rope body makes the connection more stable, avoiding loosening or falling off of the steel wire rope due to uneven stress or long-term use during operation. The strength and reliability of the connection are enhanced.

[0083] By connecting the first connection ring 22 and the third connection ring 32 to the rigid connection assembly 7, it is ensured that the flexible traction assembly can be effectively fixed to the rigid structure part of the system. The second connection ring 23 and the fourth connection ring 33 are connected to the drive motor 6, ensuring that the traction force can be accurately transmitted to the steel wire rope through the drive motor 6, thereby realizing the control of the carrier 1. The purpose of this design is to effectively combine the flexible and rigid parts, retaining the flexibility of the system while enhancing the structural stability.

[0084] The design of the steel wire rope surrounding the carrier 1 ensures that the traction force is evenly distributed on the surface of the carrier 1. This evenly distributed force avoids local stress concentration and reduces the possibility of deformation or damage to the carrier 1 caused by uneven stress. Especially in large-sized equipment, the uniform traction force can ensure the stable and accurate angle adjustment of the equipment.

[0085] The connection ring structure formed by bending and locking the ends of the steel wire rope provides higher connection strength and stability. Through the strengthening of the fixed point, the steel wire rope is not easily loosened or slipped during operation. Especially when the system operates for a long time or bears large external forces (such as wind and snow), the stability and safety of the traction system can be maintained.

[0086] Due to the high strength and wear resistance of the steel wire rope itself, and by enhancing its durability through the method of fixing with locking rings, the failure of the steel wire rope caused by fatigue or wear can be reduced. In addition, the locking connection of the steel wire rope on the rope body can avoid end breakage, reduce maintenance costs, and improve the safety and long-term reliability of the system.

[0087] The first connecting ring 22 and the third connecting ring 32 are connected to the rigid connection assembly 7, while the second connecting ring 23 and the fourth connecting ring 33 are connected to the driving machine 6, ensuring efficient transmission between the flexible traction part and the rigid structure. Such a design can not only keep the system flexible during the adjustment process but also ensure the accurate transmission of the traction force. The flexible steel wire rope reduces the vibration or impact caused by the rigid structure during the traction process, and the rigid connection part ensures the stability and accuracy of the adjustment.

[0088] By winding the flexible steel wire rope around the outside of the carrier 1 and forming connecting rings through bending and locking, the design realizes the uniform transmission of force, improves the system stability and durability. The efficient transmission design between the flexible traction assembly, the rigid connection assembly 7 and the driving machine 6 ensures the precise adjustment of the equipment during operation, and at the same time improves the safety and long-term reliability of the equipment. It well balances the advantages of the flexible and rigid parts and is suitable for application scenarios such as photovoltaic angle adjustment systems that require high precision and high stability.

[0089] Since the steel wire rope with a smaller diameter is more flexible than the one with a larger diameter and can more easily adapt to the fine adjustment of the equipment. Especially in the photovoltaic panel angle adjustment system, the smaller steel wire rope can achieve a faster response speed and higher precision, enabling the equipment to respond more quickly to the changes in the sun's position and improving the energy capture efficiency of the overall photovoltaic system.

[0090] In the existing single wire design, its diameter is at least up to 20 mm after plastic coating, and up to 22 mm. It can resist the 8-level wind and snow environment. In this solution, the diameters of the first steel wire rope 21 and the second steel wire rope 31 are in the range of 8 - 14 mm. After plastic coating, the diameter range is 10 - 16 mm. In this embodiment, the diameters of the first steel wire rope 21 and the second steel wire rope 31 are 10 mm, and the diameter after plastic coating is 12 mm. The tensile strength is 1770 Mpa, and it can resist the 8-level wind and snow environment.

[0091] Selecting steel wire ropes with smaller diameters (such as 8 - 14 mm) can reduce the material usage, thereby reducing the production and maintenance costs. Although the diameters of the steel wire ropes are reduced, they can still provide sufficient tensile strength (1770 MPa) and can resist the 8-level wind and snow environment, indicating that these smaller diameter steel wire ropes have met the requirements of practical applications in terms of strength.

[0092] Using a thinner wire rope can significantly reduce the overall weight of the system and lower the structural load. This is particularly important for large-scale photovoltaic systems because lighter components mean that the entire system can use lighter brackets and infrastructure without sacrificing stability and safety, reducing the need for structural materials and installation costs.

[0093] At the same time, the friction in the pulley 41 system is small, making the traction system more efficient. Meanwhile, the diameter after plastic coating is between 10 - 16 mm. This layer of plastic coating can effectively reduce the direct contact between the wire rope and other metal components, reduce friction and wear, and extend the service life of the wire rope and pulley 41.

[0094] The diameter of the wire rope after plastic coating (10 - 16 mm) not only provides a physical protection layer to prevent the wire rope from being corroded and aged when exposed to harsh environments, but also increases the anti-wear performance of the wire rope. This is crucial for the durability of photovoltaic systems during long-term outdoor use because it can reduce the performance degradation and failure risk of the wire rope due to environmental factors.

[0095] The diameter ranges of the first and second wire ropes 31 are 8 - 14 mm (10 - 16 mm after plastic coating), which match their tensile strength of 1770 Mpa. This combination ensures that the tensile performance of the wire rope is not sacrificed while reducing the diameter. This can ensure that the equipment can still operate normally in harsh environments such as snow and wind, and will not cause equipment failures due to wire rope breakage or failure.

[0096] The wire rope with a diameter of 10 mm (12 mm after plastic coating) selects a moderate size, which not only reduces materials and weight but also ensures sufficient strength and resistance to snow and wind. It can reduce costs and improve the convenience of construction and installation while meeting strength and environmental adaptability. The wire rope has greater flexibility and can be used in a variety of photovoltaic systems or similar equipment with different sizes and types. The smaller diameter and high-strength design also make it suitable for modern equipment with lightweight designs, which is beneficial for wide market applications and equipment transformation and upgrading.

[0097] Selecting a wire rope with a smaller diameter (8 - 14 mm, 10 - 16 mm after plastic coating) not only ensures high tensile strength (1770 Mpa) and the ability to resist grade-eight snow and wind, but also optimizes the weight, cost, and durability of the system. In this way, the design achieves lightweight, fast response speed, high durability, and stronger environmental adaptability of the equipment without sacrificing system performance and stability. Data shows that it balances safety, economy, and efficiency and is suitable for a variety of application scenarios and actual operating conditions.

[0098] In this solution, the steel wire rope used is formed by winding multiple strands of thin steel wires. Among them, the steel wire rope is usually formed by several strands (usually 6 or 8 strands) winding around a core, and each strand of the steel wire rope contains multiple small steel wires.

[0099] For example, 6x19 strands: 6 strands, each consisting of 19 thin steel wires; 6x37 strands: 6 strands, each consisting of 37 thin steel wires. If higher flexibility and greater load capacity are required, 8-strand steel wire ropes are also used.

[0100] In this embodiment, 6x37 thin steel wires are selected for winding. This structure can ensure the flexibility of the steel wire rope while providing high tensile strength, and is suitable for photovoltaic systems that require frequent angle adjustment. The design with a larger number of strands can effectively disperse the load, reduce the stress concentration of a single steel wire, and at the same time provide good wear resistance and fatigue resistance, achieving a tensile strength of 1770 MPa and the ability to resist wind and snow.

[0101] In addition, high-strength carbon steel materials are usually used for steel wire ropes. High-strength carbon steel has excellent tensile and fatigue resistance properties, can remain stable under large stress conditions, and has a certain degree of toughness to avoid brittle fracture.

[0102] To further enhance the weather resistance and corrosion resistance of the steel wire rope, galvanized steel wire ropes are used in this embodiment. The galvanized layer can effectively resist moisture, rain, snow and corrosive substances in the environment, and extend the service life of the steel wire rope. In applications such as photovoltaic systems that are long-term exposed to outdoor environments, galvanizing treatment can effectively prevent the performance degradation of the steel wire rope caused by rust.

[0103] The coating material on the outer layer of the above steel wire rope can not only enhance the corrosion resistance of the steel wire rope, but also reduce friction and wear, and improve the service life. Polyethylene (PE) can be selected as the coating material: The polyethylene coating has excellent chemical corrosion resistance and wear resistance, and at the same time has good flexibility, and can well adapt to the bending and movement of the steel wire rope.

[0104] Polyvinyl chloride (PVC): The polyvinyl chloride coating has good waterproof and chemical corrosion resistance properties, a smooth surface, and effectively reduces friction. The PVC coating is relatively hard and can provide additional mechanical protection.

[0105] Polyurethane (PU): Characteristics: The polyurethane coating has good elasticity, excellent wear resistance and tear resistance, and can provide excellent weather resistance. Compared with PE and PVC, the PU coating is softer and feels comfortable.

[0106] Nylon (PA): Characteristics: The nylon coating has extremely high wear resistance and toughness, can withstand high impact loads, and at the same time has excellent self-lubricating characteristics, reducing friction during operation.

[0107] In this embodiment, the coating is a polyvinyl chloride (PVC) coating. Due to its excellent chemical resistance, low friction coefficient, and moderate cost, it is suitable for use in general outdoor photovoltaic systems. The PE coating is flexible, can adapt to the bending and movement of the wire rope, and maintains stable performance in low-temperature environments, making it an economical and efficient choice.

[0108] The rigid connection assembly 7 includes a first connecting rod 71 connecting the first wire rope and the second wire rope 31. Both ends of the first connecting rod 71 are bent inward to form a first hook body 72 and a second hook body 73. The first hook body 72 is connected to the first connection ring 22, and the second hook body 73 is connected to the third connection ring 32.

[0109] The distance between the end of the first hook body 72, the second hook body 73 and their main body is less than 1 - 1.5 mm of the diameters of the first wire rope 21 and the second wire rope 31.

[0110] Controlling the distance between the end of the hook body and its main body within the range of 1 - 1.5 mm smaller than the wire rope diameter aims to ensure that the hook body can firmly hold the wire rope, thus preventing the wire rope from slipping or loosening during operation.

[0111] By reducing the distance between the end of the hook body and its main body, it is ensured that the wire rope is firmly fixed under the action of tension, reducing the freedom degree of the wire rope at the connection point, and thus improving the overall stress stability of the system.

[0112] The smaller distance can effectively limit the movement range of the wire rope in the hook body, reduce its relative movement in the hook body, and thus reduce the wear and fatigue caused by friction and relative displacement, improving the service life of the connection components.

[0113] By making the distance between the end of the hook body and its main body slightly smaller than the wire rope diameter, it can be ensured that the wire rope is firmly locked in the hook body under any tensile force, avoiding potential safety hazards caused by loosening or slipping. In this way, the overall connection strength is improved, especially when bearing vibration, impact or sudden loads, the connection part can remain stable.

[0114] In harsh climates such as snow and wind, the corrosion resistance of stainless steel is very excellent. Especially in wet and cold environments, its salt spray corrosion resistance can ensure long-term use. Stainless steel does not become brittle in low-temperature environments, which makes it very suitable for use in cold climate conditions, such as the snow and wind environment in the north. Among them, 316 stainless steel has stronger corrosion resistance and is suitable for harsh marine environments or occasions exposed outdoors for a long time. High strength, corrosion resistance, suitable for long-term exposure to snow, wind, wet and cold environments, and long service life. The cost is relatively high, but considering its long service life and low maintenance cost, it is still a cost-effective choice.

[0115] Galvanized carbon steel, the carbon steel itself has high strength and strong anti-deformation ability under load, and is very suitable for use in structural connection components.

[0116] Through hot-dip galvanizing treatment, a corrosion-resistant galvanized layer is formed on the surface of the carbon steel, which can effectively prevent the first connecting rod 71 from oxidation and corrosion in humid and snowy environments. Galvanized carbon steel can still maintain its strength under low-temperature conditions and is suitable for environments with low temperature and more snow and wind. The cost is relatively low, the strength is high, and the anti-corrosion performance is good after galvanizing treatment. Compared with stainless steel, the corrosion resistance is slightly worse, and regular maintenance or replacement is required when exposed to extreme conditions for a long time.

[0117] Aluminum alloy, the aluminum alloy is light in weight, but has relatively high strength after alloy treatment, and is suitable for systems that require lightweight design. Aluminum alloy itself has good corrosion resistance, especially suitable for outdoor occasions. Aluminum alloy has good weather resistance in snowy environments and can effectively resist oxidation and corrosion. 6061-T6 aluminum alloy is a high-strength and corrosion-resistant aluminum alloy, which is widely used in the construction and structural fields. It is light in weight and corrosion-resistant, suitable for occasions that need to be adjusted or moved frequently, and can be used for a long time in snowy environments. Compared with steel, although the strength is relatively high, it is slightly inferior under extremely high loads.

[0118] Fiberglass reinforced composite material, the FRP material has extremely strong corrosion resistance and can resist various erosion factors in acid-base and snowy environments. The fiberglass composite material is very light in weight, but its strength is sufficient to withstand high mechanical loads and is not easy to deform. The FRP material can maintain stable performance in extreme environments and will not become brittle or corroded due to cold or humidity. It has extremely strong corrosion resistance and weather resistance, is suitable for harsh outdoor environments, is light in weight and maintenance-free. The cost is relatively high, and under extremely high mechanical loads, the strength is inferior to metal materials.

[0119] To realize the forward and reverse rotation of the motor 63 to realize the lifting of the pull rod 64, the drive machine 6 includes a mounting shell 61, an external threaded rod 62 rotatably mounted inside the mounting shell 61, and a motor 63 for driving the external threaded rod 62 to rotate;

[0120] Two pull rods 64 penetrating through the mounting shell 61 in parallel, and internal thread lock plates 65 vertically mounted on the two pull rods 64, the internal thread lock plates 65 are threadedly connected with the external threaded rod 62;

[0121] Through the forward / reverse rotation cooperation of the motor 63 and the external threaded rod 62, the internal thread lock plate 65 is driven to drive the pull rod 64 to move up / down.

[0122] It is threadedly connected through the internal-thread locking disc 65 and the external threaded rod 62. This enables the internal-thread locking disc 65 to move up and down along the thread direction when the motor 63 drives the external threaded rod 62 to rotate. By rotating the motor 63 forward or backward, the lifting and lowering of the internal-thread locking disc 65 can be controlled, thereby driving the pull rod 64 to move up or down.

[0123] The forward or backward rotation of the motor 63 can be achieved through a precise control system, which can provide smooth and precise movement. Through the threaded structure, the rotational motion of the motor 63 is converted into a linear motion, so that the height of the pull rod 64 can be conveniently adjusted.

[0124] The mounting shell 61 protects the internal external threaded rod 62 and the motor 63 from the external environment. Especially in outdoor or harsh working environments, such as in the presence of dust, moisture, wind and snow, etc., it can ensure the long-term reliable operation of the internal mechanical structure. The mounting shell 61 also provides a stable structural foundation to ensure the smooth movement of the pull rod 64 and the threaded rod, and avoid interference from external factors to the internal motion mechanism.

[0125] Through two pull rods 64 that penetrate the mounting shell 61 in parallel, the stability and synchronism of the pull rod 64 during the lifting and lowering process can be ensured. Such a design helps to avoid the imbalance problem caused by a single pull rod 64, ensures the stability of the system during the lifting and lowering process, and avoids deviation. The internal-thread locking disc 65 is vertically mounted on the pull rod 64. Through the cooperation of the locking disc and the threaded rod, the rotational force of the motor 63 can be effectively transmitted to the pull rod 64 to achieve precise control of the pull rod 64.

[0126] By driving the rotation of the external threaded rod 62 by the motor 63, the system can achieve precise control of the position of the pull rod 64. The mechanical transmission method of threaded connection has high precision and repeatability, and is suitable for scenarios that require precise position adjustment, ensuring that the pull rod 64 can stay stably at the required height. The advantage of threaded transmission lies in its high torque transmission efficiency, and large load lifting can be achieved with a relatively small power of the motor 63.

[0127] Driven by the motor 63, the automated operation of the lifting and lowering of the pull rod 64 is realized. By adjusting the rotation direction of the motor 63, the rising and falling of the pull rod 64 can be easily achieved.

[0128] Among them, the threaded transmission system has a natural self-locking function, especially when the pitch of the threaded rod is small. When the motor 63 stops running, the threaded structure can self-lock to prevent the pull rod 64 from sliding or descending without external force. This self-locking function improves the safety of the system and avoids safety accidents caused by power failure or faults.

[0129] Due to the mechanical drive with the cooperation of internal and external threads, the system can withstand large loads without being easily deformed. Threaded connections perform well in terms of load-bearing and stability, making this design suitable for applications that require long-term heavy-load bearing, ensuring stable lifting operations under load. The design of the pull rod 64 passing through the installation shell 61 in parallel further increases the stability of the entire system, preventing the pull rod 64 from shaking or shifting during the lifting process.

[0130] It should be emphasized that sealing components are provided at the connection parts of the installation shell 61, which can effectively protect the internal threaded rod and the motor 63 from the external environment, such as dust, moisture, rain, snow, etc. This can greatly extend the service life of the system and reduce failures or maintenance requirements caused by the external environment.

[0131] The driving machine 6 further includes two connecting plates 67 symmetrically installed at the ends of the pull rod 64, and two connecting rods 68 symmetrically arranged on the connecting plates 67. The first connecting ring 22 is connected to the connecting plate 67 through the connecting rod 68. Specifically, the connecting rod 68 passes through the first connecting ring 22 and then bends to form a fixing part.

[0132] The third connecting ring 32 is connected to the connecting plate 67 through the connecting rod 68. Specifically, the connecting rod 68 passes through the third connecting ring 32 and then bends to form a fixing part.

[0133] Among them, the end of the connecting rod 68 / pull rod 64 facing the connecting plate 67 is provided with an external thread, and both the connecting rod 68 and the end of the pull rod 64 are limited and fixed by bolts.

[0134] Specifically, the length of the connecting plate 67 is divided into five equal parts, and the connecting rod 68 and the pull rod 64 are respectively arranged on the second / third equal division lines from the center area towards both sides.

[0135] By dividing the connecting plate 67 into five equal parts in length and installing the connecting rod 68 and the pull rod 64 on the second and third equal division lines respectively, a symmetrical layout can be achieved, making the system more uniform in terms of load bearing. The evenly distributed force can effectively avoid eccentric loads or stress concentrations, improving the stability of the entire structure.

[0136] And installing the connecting rod 68 and the pull rod 64 on the equal division lines close to the center helps to transfer the load to the central area of the connecting plate 67, making the force on the overall structure more balanced, reducing excessive stress concentration at the edge part, and avoiding fatigue or local deformation.

[0137] To prevent detachment and enhance fixation, the end of the connecting rod 68 is bent into a fixed hook design, which can provide additional physical constraints for the system, prevent the connecting rod 68 from slipping out of the connecting ring, and improve the safety of the connection. This design not only increases the structural stability but also enhances the seismic resistance and impact resistance, avoiding loosening problems caused by vibration or external forces.

[0138] Among them, the bending design also makes the connecting rod 68 easier to install and fix, simplifies the installation steps during the assembly process, and ensures the tightness and reliability of the installation through the self-locking characteristics of the mechanical structure.

[0139] By setting external threads at the ends of the connecting rod 68 and the tie rod 64 and fixing them through bolt limits, precise adjustment and strong fixation of the connecting rod 68 and the tie rod 64 can be achieved. This threaded structure can ensure the tight fit between the connection components and avoid loosening caused by external forces or vibrations.

[0140] Threaded connections perform excellently in terms of tensile and shear resistance. Especially for structures that need to bear large tensile or shear forces, through bolt limit fixation, the strength of the connection point can be further enhanced to prevent slipping or fracture under high stress conditions.

[0141] It should be emphasized that there are no less than 2 bolts set at each connection.

[0142] To ensure that the motor 63 can still work reliably in low-temperature and cold environments, usually the following types of motors 63 are selected, which can not only meet the basic driving requirements but also have cold resistance and stability:

[0143] Such as a three-phase asynchronous motor dedicated to low-temperature environments. This type of motor uses low-temperature dedicated materials and lubricating oil in its design and can operate normally in cold environments. The three-phase asynchronous motor has strong load adaptability and stability, can maintain long-term stable operation under harsh conditions such as snow and wind, and is suitable for systems that require high power and continuous operation. Although the heat dissipation problem of the motor is relatively less serious in low-temperature environments than in high-temperature environments, the good heat dissipation design of the three-phase asynchronous motor can still ensure the normal operation of the motor under extreme conditions.

[0144] Brushless DC motor. The brushless DC motor has high efficiency and good energy consumption performance in cold environments, and can work for a long time without excessive energy loss. Since there are no brushes, the BLDC motor can also avoid performance degradation caused by component wear in low-temperature environments, while reducing maintenance requirements, especially suitable for the drive systems of outdoor equipment in cold regions. The brushless DC motor can still maintain good starting performance at low temperatures and will not have difficulty starting due to too low temperatures. The BLDC motor is suitable for precise control scenarios, such as automation equipment, robots, and wind power equipment in cold regions.

[0145] Permanent magnet synchronous motor, the efficiency of PMSM motor is higher than that of asynchronous motor. Especially the motor using rare earth permanent magnet materials can maintain stable magnetic performance in extremely cold environment and will not affect the operation of the motor due to temperature change. Since the rare earth permanent magnet materials can still maintain strong magnetism in low temperature environment, the motor can still maintain high power output and efficient operation in low temperature. Some PMSM motors will use special bearing lubricating oil and low temperature materials.

[0146] In this embodiment, the motor adopts a permanent magnet synchronous motor with stable magnetic performance, which is suitable for precision control occasions and can still maintain efficient operation in low temperature environment. It not only has good cold resistance performance, but also can ensure the reliability and stability of the system under bad weather conditions.
