The development and utilization of new energy and renewable energy have attracted much attention. As a clean renewable new energy, solar energy has gradually entered people's daily life.

[0003] The photovoltaic support is a special support designed for placing, installing and fixing the solar panel in the solar photovoltaic power generation system. The general materials are aluminum alloy, carbon steel and stainless steel. The inclined single axis tracking support is one of the photovoltaic supports. The inclined single axis tracking support refers to a support that rotates around a north-south inclined axis to track the sun. The rotating shaft is inclined, and a three-point support structure is generally used. The inclined single axis support is more suitable for medium and high latitude areas.

[0004] As disclosed in the Chinese patent with the patent publication number CN114217642A, a multi-column inclined single-axis tracking photovoltaic support for solar energy is disclosed, which comprises a support base, a column one, a column two, a top support seat, a support frame and an angle control device. The support frame can install a photovoltaic panel thereon. The support frame is installed on the top support seat with a fixed inclination in the north-south direction and can rotate in the east-west direction. The rotation is driven by the angle control device. The angle control device comprises a driving wheel arranged on the support frame, a plurality of transmission wheels installed on the column, a plurality of driving ropes wound around the driving wheel and the transmission wheels, and a driving rod installed on the column. The movement output end of the driving rod is fixedly connected with the driving rope. The driving rod drives the driving rope to reciprocate. The plurality of driving ropes drive the driving wheel to rotate, thereby driving the support frame to rotate in the east-west direction. At the same time, the use of the innovative driving system makes the multi-column inclined single-axis tracking photovoltaic support stable and reliable, and the cost is further reduced. In summary, the use of low-cost intelligent tracking photovoltaic support can maximize the power generation of photovoltaic projects, thereby improving the project benefits.

[0007] Second, the driving rope is easily deformed due to environmental factors such as temperature and wind, so that the transmission accuracy fluctuates with the environment, such as the change of the elastic modulus when the temperature changes, resulting in unstable angle control accuracy, affecting the tracking support to track the sun position, and further reducing the solar energy utilization efficiency.

[0008] Third, the driving rope is easily affected by environmental factors such as ultraviolet rays, wind and rain, which will cause aging and wear, reduce the service life, and need frequent inspection and replacement, affecting the normal operation of the support system.

[0009] Fourth, the driving rope will have energy loss due to its flexibility and friction characteristics between the transmission wheel and the driving wheel, and the transmission efficiency is relatively low when the surface is not smooth.

[0010] Fifth, the driving rope has limited carrying capacity, and may not withstand the load pressure when facing large-area photovoltaic panel installation or severe weather, which may cause rupture or normal driving risk, affecting the reliability of the support system.

DETAILED DESCRIPTION

[0042] 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.

[0043] like Figures 1-9 As shown, a rigid chain driven inclined single-axis tracking bracket includes a rotatable main beam 1. The top of the main beam 1 is provided with several sets of purlin assemblies 2 for installing photovoltaic modules. The bottom of the main beam 1 near its two ends is provided with a front support assembly 3 and a rear support assembly 4 for supporting the rotation of the main beam 1. A rigid chain drive assembly 5 for driving the rotation of the main beam 1 is provided between the rear support assembly 4 and the main beam 1. One end of the rigid chain drive assembly 5 is hinged to the rear support assembly 4, and the other end of the rigid chain drive assembly 5 is connected to the main beam 1 through a swing arm assembly 6.

[0044] The rigid chain drive assembly 5 includes a chain storage shell 51 hinged to the rear support assembly 4. A chain winding seat is provided inside the chain storage shell 51. Two rigid chain grooves 55 are symmetrically arranged inside the chain winding seat. Rigid chains 52 that can slide along the rigid chain grooves 55 are evenly distributed in the rigid chain grooves 55. The two rigid chains 52 are interlocked or separated. The free ends of the rigid chains 52 extend out of the chain storage shell 51 and are fixedly connected to push-pull heads 53. The push-pull heads 53 are hinged to the swing arm assembly 6. A drive sprocket 56 is provided on the chain winding seat outside one of the rigid chains 52. One side of the drive sprocket 56 is engaged with the corresponding rigid chain 52. The drive sprocket 56 is driven by a self-locking geared motor 54, which is fixedly mounted on the chain storage shell 51.

[0045] This design ensures that, firstly, the rigid chain 52 deforms minimally under stress, accurately transmitting power. Thus, when driving the main beam 1 to rotate, whether under heavy loads or frequent start-stop cycles, the rigid chain 52 guarantees the stability and accuracy of power transmission. This effectively avoids deviations in the rotation angle control of the main beam 1 due to inaccurate transmission caused by elastic deformation. Consequently, the photovoltaic modules mounted on the purlin assembly 2 of the main beam 1 can maintain accurate tracking of sunlight as the main beam 1 rotates precisely, ensuring that photovoltaic power generation efficiency is unaffected by these factors.

[0046] Secondly, the rigid chain 52 in the rigid chain drive assembly 5 is usually made of materials with good weather resistance, and has a relatively compact structure, which has strong resistance to environmental factors such as ultraviolet rays, wind and rain, so that it will not easily age and wear out like the driving rope during long-term outdoor use, and does not need to be frequently inspected and replaced, thereby ensuring the continuous and normal operation of the support system, reducing the operation and maintenance cost, and reducing the interference to photovoltaic power generation caused by frequent maintenance.

[0047] Thirdly, in the rigid chain drive assembly 5, the rigid chain 52 in the chain winding seat slides in the rigid chain groove 55 and is closely meshed with the driving sprocket 56, and this meshing mode can realize efficient power transmission; and the transmission connection between the self-locking speed reducer 54 and the driving sprocket 56 can accurately adjust the rotating speed and torque according to actual needs, further optimizing the power transmission process, so that the energy loss is small during the rotation of the whole driving girder 1, effectively improving the transmission efficiency, enabling the photovoltaic support to operate in a more efficient manner, and thereby improving the overall performance of the photovoltaic power generation system.

[0048] Finally, in the inclined single-axis tracking support driven by the rigid chain, the rigid chain 52 has high bearing capacity and can withstand large load pressure, so that whether it is a heavy load caused by large-area photovoltaic panel installation or an additional force on the support under adverse weather conditions (such as strong wind, heavy snow, etc.), the rigid chain can stably support and drive the girder 1 to rotate, ensuring the reliability of the support system and effectively avoiding problems such as photovoltaic support failure and photovoltaic power interruption caused by insufficient bearing capacity, thereby ensuring the long-term stable operation of the photovoltaic power generation project.

[0049] In the present embodiment, the chain winding seat is cast from high-strength aluminum alloy material.

[0050] In the present embodiment, the chain storage shell 51 is made of carbon steel and the surface is galvanized.

[0051] The rigid chain groove 55 includes a spiral winding groove and a guide groove connected to the winding groove, and the outer end of the guide groove is in a straight line shape.

[0052] Firstly, the spiral winding groove can increase the rigid chain winding length in the limited chain storage shell 51 space, reduce the length direction space occupation, and make the equipment more compact, thereby optimizing the layout, reducing the occupied area, and improving the space utilization rate in the application of the inclined single-axis tracking support.

[0053] Secondly, the spiral winding groove allows the chain to be wound in an orderly spiral trajectory, avoiding entanglement, knotting or accumulation, ensuring orderly winding, facilitating subsequent release and use, reducing chain jamming and other failures, and improving system reliability.

[0054] Again, the guide groove is in communication with the winding groove and the outer end is straight, which provides accurate guide for the rigid chain from winding to stretching transmission, so that the chain is adjusted to straight motion state after entering the guide groove from the spiral winding groove, and leaves the chain storage shell 51 in the predetermined straight line direction, thereby ensuring the angle adjustment accuracy of the swing arm assembly 6 and the main beam 1 and the photovoltaic module, and the straight line part of the guide groove can ensure the stability of the chain stretching, limit the lateral movement, make the chain stretch linearly, reduce the shaking and deviation, improve the stability of the transmission system, reduce the wear of the chain and the driving sprocket 56 and other components, prolong the service life of the equipment, and ensure the accurate tracking of the photovoltaic module to the sun.

[0055] The rigid chain 52 is a component known to those skilled in the art, and its structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods, therefore, in this embodiment, it is not described in detail.

[0056] In this embodiment, the inner chain plate and the outer chain plate in the rigid chain 52 are made of carbon steel, and are subjected to quenching and tempering treatment, and the pin shaft and the sleeve in the rigid chain 52 are made of alloy steel and are subjected to chrome plating treatment on the surface.

[0057] In this embodiment, the self-locking speed reducer motor 54 is a worm gear speed reducer motor.

[0058] The worm gear speed reducer motor is a prior art, and is a component known to those skilled in the art, and its structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods, therefore, in this embodiment, it is not described in detail.

[0061] Secondly, the stand column 32 is symmetrically provided with the fixed plates 33 at the top and the front bearing assembly 34 is installed, which can provide a stable installation position and accurate positioning, and ensure the smooth rotation of the main beam 1.

[0062] Thirdly, the components cooperate to bear force, the pressure is dispersed through the bottom plate 31, the force is transmitted and converted through the stand column 32 to reasonably distribute the stress, which can prolong the service life of the assembly and ensure the long-term stable operation of the system.

[0063] The rear support assembly 4 comprises two support rods 41 arranged in an inclined manner, the ends of the two support rods 41 close to each other are hingedly connected with a mounting plate 42, and the other ends of the two support rods 41 are spaced apart by a certain distance and are respectively fixedly connected with support plates 43.

[0064] The two support rods 41 are connected with a cross rod 44, and the two support rods 41 and the cross rod 44 form a triangular structure.

[0065] In this embodiment, the overall structure of the cross rod 44 is L-shaped.

[0066] In addition to this embodiment, the cross section can also be customized as needed to meet the force requirement.

[0067] The top end of the mounting plate 42 is fixedly connected with a rear bearing assembly 45, and the front bearing assembly 34 and the rear bearing assembly 45 together support the rotation of the main beam 1.

[0068] The other end of the mounting plate 42 is fixedly connected with a mounting seat 46, and the mounting seat 46 is hingedly connected with the rigid chain driving assembly 5 through a pin shaft.

[0069] In this way, firstly, the triangular structure composed of the two support rods 41 and the cross rod 44 has high stability, so that it can resist external forces in different directions in the mechanical structure, and is not easy to deform and twist when bearing load, and can maintain its own shape when subjected to external forces such as lateral forces generated by the rotation of the main beam 1, effectively supporting the main beam 1, and the obliquely arranged support rods 41 reasonably disperse the force borne by them to the entire triangular structure through the cross rod 44, and when vertical downward pressure acts, the force can be transmitted to the support plates 43 in the axial direction and reasonably distributed between the two support rods 41, avoiding excessive local stress and prolonging the service life of the assembly.

[0070] Secondly, the ends of the two support rods 41 close to each other are hingedly connected with the mounting plate 42, which can be conveniently adjusted in angle during installation to cooperate with the main beam 1, and the mounting plate 42 can adaptively rotate when the main beam 1 rotates, reducing stress concentration and part wear, ensuring smooth operation, and the mounting seat 46 at the other end of the mounting plate 42 is hingedly connected with the rigid chain driving assembly 5 through a pin shaft, and the two can realize flexible relative movement, and the action of the rigid chain can drive the coordinated movement of related parts, and the hinge point can be adjusted moderately, further improving the smoothness and reliability of the device operation.

[0071] Thirdly, the rear bearing assembly 45 at the top of the mounting plate 42 cooperates with the front bearing assembly 34 to support the rotation of the main beam 1 from different positions, share the weight, friction force and other external forces, make the rotation more stable and reliable, and also can accurately control the rotation trajectory, improve the operation precision of the device.

[0072] Finally, the support plate 43 at the other end of the support rod 41 is in contact with the ground or the like, providing stable base support, evenly distributing force, preventing excessive local pressure and unstable support, and ensuring reliable support for the structure above.

[0073] The swing arm assembly 6 comprises two mounting rods 61 symmetrically arranged on both sides of the rear bearing assembly 45, and both of the mounting rods 61 are located above the main beam 1.

[0074] The two mounting rods 61 are integrally connected with a connecting lug 62 on one side away from each other, and the connecting lug 62 is fixedly connected with the main beam 1 by a plurality of bolts.

[0075] One end of each of the two mounting rods 61 is fixedly connected with a connecting rod 63, and the bottom of the connecting rod 63 is fixedly installed with a connecting seat 64, which is hingedly connected with the rigid chain drive assembly 5 through a pin shaft.

[0076] In this way, the two mounting rods 61 of the swing arm assembly 6 are symmetrically arranged on both sides of the rear bearing assembly 45, and during the operation of the device, this symmetrical layout can evenly share the load of the two mounting rods 61, effectively maintaining the balance of the device, and avoiding tilting or instability due to excessive force on one side.

[0077] Secondly, the mounting rod 61 is fixed with the main beam 1 by the integrally connected connecting lug 62 and a plurality of bolts. This connection method is very firm and reliable, has high carrying capacity, can withstand external force impact and vibration during the operation of the device, and thus ensures the structural integrity of the entire device and ensures the normal operation of the device.

[0078] Thirdly, one end of the mounting rod 61 is connected with the rigid chain drive assembly 5 in a hinged manner through the connecting rod 63 and the connecting seat 64, so that the swing arm assembly 6 and the rigid chain drive assembly 5 can move flexibly relative to each other, and can well adapt to various actions such as extension and contraction of the rigid chain 52, thereby ensuring the smoothness of the cooperative work between the two.

[0079] The front bearing assembly 34 and the rear bearing assembly 45 have the same structure. The front bearing assembly 34 comprises a bearing seat 341, and a rotating bearing 342 is installed in the bearing seat 341. The main beam 1 is fixedly and sequentially arranged in the rotating bearings 342, so that the main beam 1 can rotate around its axis.

[0080] The rotating bearings 342 are made of high molecular materials.

[0081] In this way, firstly, the polymer material is generally lighter than metal, which helps to reduce the weight of the overall structure; secondly, the polymer material has good self-lubricating property, reduces friction and wear, and reduces maintenance cost; thirdly, the polymer material can resist the erosion of various chemicals, prolonging the service life.

[0082] The purlin assembly 2 comprises a purlin 21, the bottom of the purlin 21 is fixedly connected with a reinforcing rod 22 on both sides of the main beam 1 in a symmetrical manner, the other end of the two reinforcing rods 22 is connected together and located below the main beam 1, and the main beam 1 and the two reinforcing rods 22 form a triangular structure.

[0083] The main beam 1 is provided with a fastening bolt 23 on both sides in a symmetrical manner, and the fastening bolt 23 extrudes and fixes the reinforcing rod 22 and the purlin 21 on the main beam 1.

[0084] In this way, firstly, the triangular structure formed by the main beam 1 and the reinforcing rod 22 has strong stability, can stably support the photovoltaic assembly, resist deformation in bad weather, and ensure normal operation; it can also adapt to different terrain conditions, ensure the stability of the support and the photovoltaic assembly at a suitable installation angle to achieve the best power generation efficiency.

[0085] Secondly, the fastening bolt 23 tightly fixes each component on the main beam 1, which can prevent loosening and displacement, ensure that the components cooperatively bear the load and transfer the load to the supporting structure such as the ground foundation, and improve the installation precision and efficiency, thereby providing good conditions for the installation of the photovoltaic assembly.

[0086] Thirdly, the purlin assembly 2 optimizes the load transfer path, reasonably shares the load, prolongs the service life of the purlin assembly 2, reduces the maintenance cost, improves the overall bearing capacity, and meets the installation requirements of photovoltaic projects in different regions.

[0087] In the embodiment, the purlin 21 is made of cold-formed thin-walled steel, and a few-shaped steel is used.

[0088] In addition to the embodiment, the cross section and material can also be customized as needed to meet the force requirement.

[0089] The purlin 21 is arranged above the main beam 1 and arranged longitudinally along the main beam 1, and the arrangement spacing is matched with the size of the upper photovoltaic panel.

[0090] In the embodiment, the main beam 1 is made of a mouth-shaped steel.

[0091] In addition to the embodiment, the cross section and material can also be customized as needed to meet the force requirement.

[0092] In the embodiment, the upright column 32 and the support rod 41 are made of a mouth-shaped steel.

[0093] In addition to the embodiment, the cross section and material can also be customized as needed to meet the force requirement.

[0094] The inclined single-axis tracking support is equipped with a photovoltaic tracking control system, sensors, etc. according to the use requirements.

[0095] The photovoltaic tracking control system and the sensors are prior art, and their structures, working principles and installation principles all constitute prior art and are well known to those skilled in the art, and thus will not be described here.

[0096] In specific use, after installation is completed, the rigid chain driven inclined single-axis tracking support is in an initial static state; at this time, the main beam 1 is kept at a certain inclination angle (initial angle set by the inclined single-axis) through the front support assembly 3 and the rear support assembly 4, so as to better receive sunlight at a specific time period in a day; meanwhile, a plurality of groups of purlin assemblies 2 are installed at the top of the main beam 1 and are in a state of waiting for installation of photovoltaic assemblies or have installed photovoltaic assemblies and are ready to start tracking the sun.

[0097] When the position of the sun starts to change and the angle of the main beam 1 needs to be adjusted so that the photovoltaic assemblies thereon can continuously maintain a good light collecting angle, the control system (usually an intelligent control system matched with the photovoltaic system, which can determine when to start tracking adjustment according to time, geographical position, solar angle algorithm and other information, and thus is prior art, and thus will not be described in detail in this embodiment) will issue a command to start the work of the rigid chain drive assembly 5.

[0098] Subsequently, after receiving the start command of the control system, the self-locking reduction motor 54 starts to operate. As a power source, the output shaft of the self-locking reduction motor 54 drives the driving sprocket 56 connected in transmission to start rotating. During the rotation of the driving sprocket 56, since one side of the driving sprocket 56 is engaged with the corresponding rigid chain 52, the rigid chain 52 will be driven to slide along the rigid chain groove 55.

[0099] Meanwhile, since the two rigid chains 52 are designed to be mutually engaged and separated, when one of the rigid chains 52 is driven by the driving sprocket 56, the other rigid chain 52 cooperating therewith will also move synchronously, ensuring the coordination and stability of the entire transmission process.

[0100] With the sliding of the rigid chain 52 in the rigid chain groove 55, the free end of the rigid chain 52 penetrates out of the chain storage shell 51 and is fixedly connected with the push-pull head 53, so as to drive the push-pull head 53 to produce a corresponding displacement. The displacement of the push-pull head 53 is transmitted to the swing arm assembly 6 through force transmission.

[0101] After receiving the force transmitted from the push-pull head 53, the swing arm assembly 6 will convert the force into a rotational driving force for the main beam 1 according to its own mechanical structure and connection mode, so as to drive the main beam 1 to start rotating around the connection points of the main beam 1 with the front support assembly 3 and the rear support assembly 4.

[0102] In this process, the rotation angle of the main beam 1 will gradually change to adapt to the change of the sun position, so that the photovoltaic module installed on the purlin assembly 2 can always face the sun light as much as possible, ensuring the best lighting effect and power generation efficiency.

[0103] As the sun moves in the sky, the control system will continue to monitor and determine whether further adjustment of the angle of the main beam 1 is needed according to the preset algorithm and parameters; if needed, the self-locking reduction motor 54 will continue to operate or make corresponding speed adjustment according to the instruction of the control system, and the angle of the main beam 1 is constantly fine-tuned through the above transmission link (drive sprocket 56-rigid chain 52-push-pull head 53-swinging arm assembly 6), ensuring that the photovoltaic module always remains in the optimal lighting angle range.

[0104] When the sun sets or the light condition is no longer suitable for effective photovoltaic power generation (such as overcast, night, etc.), the control system will issue an instruction to stop the operation of the self-locking reduction motor 54, and at this time the rigid chain drive assembly 5 stops working and the main beam 1 stops at the current angle position.

[0105] In some cases, for example, the main beam 1 needs to be restored to the initial set angle position in the morning of the next day in order to start a new day of tracking work, the control system can also issue an instruction to make the self-locking reduction motor 54 operate in reverse, and through the rigid chain drive assembly 5 to drive the main beam 1 to rotate in reverse, the main beam 1 is reset to the initial angle.

[0106] In summary, the rigid chain driven inclined single-axis tracking support can accurately adjust the angle of the main beam 1 according to the change of the sun position through the above series of working steps, so as to realize the effective tracking of the photovoltaic module to the sun light and improve the photovoltaic power generation efficiency.

[0107] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
