[0009] Fourth, the drive mechanism, eccentric bearing and other key components of the above-mentioned flat single-axis tracking support are prone to wear and fatigue due to use and environmental factors in long-term use, which reduces the service life of the system and shortens the service life.

[0010] Fifth, in high temperature, low temperature, sand and other harsh environments, the above-mentioned flat single-axis tracking support is easily affected, such as the performance of the drive mechanism is affected in high temperature, resulting in tracking accuracy decline, and the eccentric bearing and damper are prone to failure due to sand invasion in sand environment, and the environmental adaptability is poor.

[0011] Sixth, the aluminum alloy ladder purlin has high material cost, large-scale use will increase the construction cost, and the performance has limitations in extreme conditions, and is prone to wear in high wind and sand area, and needs more frequent inspection and maintenance.

[0016] The utility model discloses the further optimization of above-mentioned technical scheme is as follows:

[0025] In the utility model, the self-locking speed reducer transmits power through the meshing of the driving sprocket and the rigid chain, and the power transmission precision is high. Meanwhile, due to the stable sliding of the rigid chain in the rigid chain groove and the accurate meshing with the driving sprocket, the rotary motion of the self-locking speed reducer can be accurately converted into the linear motion of the rigid chain, and then through the accurate control of the self-locking speed reducer, the accurate swing angle of the swing arm assembly can be realized, so that the rotation angle and speed of the main beam can be accurately controlled, the photovoltaic panel can track the position change of the sun with extremely high precision, and the utilization efficiency of solar energy is improved.

[0026] This invention ensures efficient power transmission from the self-locking geared motor to the drive sprocket through a transmission connection design between the self-locking geared motor and the drive sprocket. Simultaneously, the sliding friction of the rigid chain within the rigid chain groove is low, and the meshing of the drive sprocket and the rigid chain effectively transmits power to the rigid chain, reducing power loss during transmission. This allows the output power of the self-locking geared motor to be converted into effective power for driving the main beam rotation to the maximum extent, thereby improving the overall drive efficiency of the support structure and reducing energy waste.

[0027] This invention utilizes a rigid chain drive component that can transmit power while also withstanding certain tensile and compressive forces. Therefore, during the entire operation of the tracking bracket, when the main beam rotates or is subjected to external forces, the rigid chain can stably transmit the force, thereby stably driving the single-axis rotation, ensuring the normal operation of the system, and guaranteeing that the photovoltaic panels always maintain a good orientation to obtain the best solar energy reception effect.

The shell itself is made of corrosion-resistant and high-strength materials, improving the entire system's resistance to harsh environments.

DETAILED DESCRIPTION

[0040] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0041] As shown in Figures 1-7 A rigid chain driven flat single-axis tracking support, comprising a plurality of stand 1 arranged at intervals and on the same straight line, the top of the stand 1 is rotatably connected with the same main beam 3 through the bearing assembly 2, the main beam 3 is provided with a plurality of purlin 4 for installing photovoltaic panels, the rigid chain drive assembly 5 for driving the rotation of the main beam 3 is arranged between part of the stand 1 and the main beam 3 respectively, both ends of the rigid chain drive assembly 5 are connected with the main beam 3 and the corresponding stand 1 through the swing arm assembly 6 and the mounting assembly 7 respectively;

[0042] The rigid chain driving assembly 5 comprises a chain receiving shell 51 arranged on the mounting assembly 7, a chain winding seat is arranged in the chain receiving shell 51, two rigid chain grooves 55 are symmetrically arranged in the chain winding seat, rigid chains 52 which can slide along the rigid chain grooves 55 are uniformly arranged in the rigid chain grooves 55, the two rigid chains 52 are mutually buckled or separated, the free ends of the two rigid chains 52 are arranged to pass through the chain receiving shell 51 and are fixedly connected with the same push-pull head 53, the push-pull head 53 is hingedly connected with the swing arm assembly 6, a driving sprocket 56 is arranged on the chain winding seat and located outside one of the rigid chains 52, one side of the driving sprocket 56 is engaged with the corresponding rigid chain 52, the driving sprocket 56 is drivingly connected with a self-locking speed reducer motor 54, and the self-locking speed reducer motor 54 is fixedly installed on the chain receiving shell 51.

[0043] In this way, first, the self-locking speed reducer motor 54 transmits power through the engagement of the driving sprocket 56 and the rigid chain 52, the power transmission accuracy is high, and at the same time, due to the stable sliding of the rigid chain 52 in the rigid chain 52 groove and the precise engagement with the driving sprocket 56, the rotary motion of the self-locking speed reducer motor 54 can be accurately converted into the linear motion of the rigid chain 52, and then through the precise control of the self-locking speed reducer motor 54, the accurate swing angle of the swing arm assembly 6 can be realized, thereby the rotation angle and speed of the main beam 3 can be accurately controlled, the photovoltaic panel can track the position change of the sun with extremely high accuracy, and the utilization efficiency of solar energy is improved.

[0044] Second, the driving connection design between the self-locking speed reducer motor 54 and the driving sprocket 56 ensures efficient power transmission from the self-locking speed reducer motor 54 to the driving sprocket 56, at the same time, the sliding friction of the rigid chain 52 in the rigid chain 52 groove is small, and the engagement of the driving sprocket 56 and the rigid chain 52 can effectively transmit power to the rigid chain 52, reducing the loss of power in the transmission process, so that the output power of the self-locking speed reducer motor 54 can be maximized to convert into effective power for driving the rotation of the main beam 3, thereby improving the driving efficiency of the entire support and reducing energy waste.

[0045] Third, the rigid chain driving assembly 5 can withstand certain tension and pressure while transmitting power, so that during the operation of the entire tracking support, when the main beam 3 rotates or bears external force, the rigid chain 52 can stably transmit force, thereby stably driving the flat single shaft to rotate, ensuring the normal operation of the system and ensuring that the photovoltaic panel can always maintain a good orientation to obtain the best solar energy receiving effect.

[0046] Fourth, the rigid chain 52 has a simple structure without complex electronic or hydraulic elements, is less susceptible to electromagnetic interference, temperature changes and other factors, has high reliability of mechanical components, has a long service life, can maintain stable performance in long-term outdoor use environment, and reduces system maintenance costs and downtime.

[0047] Fifth, the chain storage shell 51 centrally encapsulates key components of the rigid chain drive assembly 5 together, facilitates inspection and maintenance by maintenance personnel, and the rigid chain 52 has relatively fewer components and a relatively simple structure, so when maintenance or component replacement is required, the operation is relatively easy, the maintenance personnel can quickly inspect, repair and replace components of the rigid chain 52 drive system, shorten the maintenance time, and improve the usability of the system.

[0048] Sixth, in outdoor environments such as deserts, coastal areas and other areas, there may be harsh weather conditions such as sand, smoke, high temperature, low temperature and the like. The chain storage shell 51 encapsulates the key parts of the rigid chain 52 drive assembly, provides a relatively closed environment for the rigid chain 52, blocks impurities and moisture such as sand, smoke, rainwater and the like from entering, and protects the rigid chain 52; and is made of a material with high corrosion resistance and strength, thereby improving the resistance of the entire system to harsh environments.

[0049] The rigid chain 52 is a component known to those skilled in the art, and its structure and principle are known to those skilled in the art, so it is not described in detail in this embodiment. 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. 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.

[0050] In this embodiment, the chain winding seat is made of high-strength aluminum alloy material.

[0051] In this embodiment, the chain storage shell 51 is made of carbon steel and is subjected to zinc plating treatment on the surface.

[0052] 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.

[0053] In this way, first, the spiral winding groove can increase the winding length of the rigid chain 52 in the limited space of the chain storage shell 51, reduce the length direction space occupation, make the equipment more compact, optimize the layout in the flat single-axis tracking support application, reduce the floor area, and improve the space utilization.

[0054] Second, the spiral winding groove allows the chain to be wound in an orderly spiral trajectory, avoids entanglement, knotting or accumulation, ensures that the winding is neat, facilitates subsequent release and use, reduces chain jamming and other failures, and improves the reliability of the system.

[0055] Furthermore, the guide groove is connected to the take-up groove and its outer end is straight, which provides precise guidance for the rigid chain 52 from take-up to extension. After the rigid chain 52 enters the guide groove from the spiral take-up groove, it is adjusted to a linear motion state and leaves the chain storage shell 51 in a predetermined straight direction. This ensures the accuracy of the angle adjustment of the swing arm assembly 6, the main beam 3, and the photovoltaic panel. At the same time, the straight part of the guide groove can ensure the motion stability of the rigid chain 52 when it extends, limit lateral movement, make the rigid chain 52 extend and retract linearly, reduce swaying and deviation, improve the stability of the transmission system, reduce the wear of the rigid chain 52 and the drive sprocket 56 and other components, extend the equipment life, and ensure that the photovoltaic panel accurately tracks the sun.

[0056] In this embodiment, the self-locking geared motor 54 is a worm gear reducer motor.

[0057] The worm gear reducer motor is existing technology and is a component known to those skilled in the art. Its structure and principle are known to those skilled in the art, therefore, it will not be described in detail in this embodiment.

[0058] The main beam 3 includes at least one beam segment, and adjacent beam segments are connected together by connectors 8.

[0059] This design firstly divides the main beam 3 into multiple beam segments, making transportation and on-site assembly easier and reducing transportation difficulty and costs; secondly, it allows for flexible adjustment of the number and length of beam segments according to actual needs, adapting to different site and photovoltaic panel layout requirements; thirdly, if a beam segment has a problem, that segment can be replaced individually without replacing the entire main beam 3, reducing maintenance costs; and finally, it facilitates the addition or reduction of beam segments as needed to meet ever-changing requirements.

[0060] The connector 8 includes two Z-shaped connecting plates facing each other, and the two Z-shaped connecting plates are connected together by multiple bolts.

[0061] The two ends of the zigzag connecting plate are respectively connected to the corresponding beam segments by multiple bolts.

[0062] This design, firstly, allows the U-shaped connecting plate to better adapt to the shape and structure of the beam segment, increasing the stability and reliability of the connection; secondly, the use of bolted connections makes the assembly and disassembly of the beam segment more convenient, which not only improves construction efficiency but also facilitates the maintenance and replacement of the beam segment.

[0063] The swing arm assembly 6 includes two mounting rods 61 symmetrically arranged on both sides of the column 1, and both mounting rods 61 are located below the main beam 3.

[0064] The upper part of the main beam 3 and the two sides of the bearing assembly 2 are symmetrically provided with a limiting plate 62, and the limiting plate 62 corresponds to the mounting rod 61 one by one from top to bottom.

[0065] In this way, through the arrangement of the limiting plate 62, the sliding of the bearing assembly 2 on the main beam 3 can be effectively avoided, so that the overall structure of the photovoltaic support is more stable, the wind resistance and other abilities are improved, the photovoltaic panel can be accurately aligned with the sunlight, the power generation efficiency is improved, and unnecessary wear of the bearing assembly 2 and the main beam 3 due to sliding is reduced, thereby prolonging the service life.

[0066] The limiting plate 62 and the mounting rod 61 are symmetrically provided with a plurality of connecting bolts 63 between the two sides of the main beam 3, and the connecting bolts 63 are extruded and fixedly connected together with the limiting plate 62, the mounting rod 61 and the main beam 3.

[0067] In this way, the various components are tightly combined to form a solid whole, the stability of the support is improved, the deformation under external force can be effectively resisted, the shape and strength of the structure are maintained, unnecessary movement between the limiting plate 62, the mounting rod 61 and the main beam 3 is avoided, the accuracy of the position is ensured, the connecting bolts 63 evenly share the stress, local stress concentration is prevented, the service life of the components is prolonged, and in addition, this connection method is simple and reliable, and convenient for installation and disassembly operation when needed.

[0068] One end between the two mounting rods 61 is fixedly connected with a connecting rod 64, the bottom of the connecting rod 64 is fixedly connected with a connecting seat 65, and the push-pull head 53 is hingedly connected with the corresponding connecting seat 65.

[0069] In this way, first, the connecting rod 64 and the connecting seat 65 enhance the structural rigidity and stability, which is transversely strengthened between the two mounting rods 61 to prevent the mounting rod 61 from being laterally deformed or twisted, which is crucial for maintaining the relative position of the rigid chain 52 drive assembly and the main beam 3 and the stand 1, ensuring accurate and reliable power transmission, and under the influence of external factors such as wind load and vibration, this stable structure can better resist external force, reduce the shaking and deviation of the main beam 3, and make the photovoltaic panel maintain the correct angle to efficiently receive solar energy.

[0070] Second, the push-pull head 53 is hingedly connected with the connecting seat 65, which can better adapt to different positions and stress conditions in the movement of the rigid chain drive assembly 5, and the hinge point can adjust the angle when the push-pull head 53 is stretched or swung, avoiding the problem of being stuck or excessively constrained, making the rotation adjustment of the main beam 3 more smooth and flexible, and improving the convenience of operation.

[0071] Third, the stress of the rigid chain drive assembly 5 is dispersed to the mounting rod 61 through the connecting rod 64 and the connecting seat 65, reducing the local stress concentration and further enhancing the durability of the support.

[0072] Fourth, the design is convenient for installation and maintenance, the connecting rod 64 and the connecting seat 65 can be pre-assembled and installed as a whole, and only the rigid chain driving assembly 5 and the connecting seat 65 need to be hinged on site, so that the installation is convenient and the error is small; when overhauling, the rigid chain driving assembly 5 can be separated by disconnecting the hinge connection, the structure is simple and easy to operate, and the maintenance difficulty and cost can be reduced.

[0073] The mounting assembly 7 comprises a mounting seat 71 fixedly mounted on the stand 1, a fixed pin shaft 72 rotatably arranged in the mounting seat 71, and a mounting plate 73 hinged to the mounting seat 71 through the fixed pin shaft 72, and the other end of the mounting plate 73 is fixedly connected with the chain storage shell 51.

[0074] In this way, the rigid chain driving assembly 5 is not only convenient to install and disassemble, but also more convenient during maintenance and overhaul; secondly, the hinged mode of the fixed pin shaft 72 enables the mounting plate 73 to rotate flexibly relative to the mounting seat 71, better adapts to the adjustment of the angle of the main beam 3, and ensures the normal operation of the support.

[0075] The bearing assembly 2 comprises a bearing seat mounted at the top of the stand 1, rotating bearings are mounted in the bearing seat, and the main beam 3 is fixedly arranged in the rotating bearings in sequence, so that the main beam 3 can rotate around the axis direction thereof.

[0076] The rotating bearings are all made of high polymer material.

[0077] Firstly, the high polymer material is usually lighter than metal, which helps to reduce the weight of the overall structure; secondly, the high polymer material has good self-lubricating property, which reduces friction and wear and tear, and reduces maintenance cost; thirdly, the high polymer material can resist the corrosion of various chemicals, prolonging the service life.

[0078] In the embodiment, the purlin 4 is made of cold-formed thin-walled steel, and a C-shaped steel is used.

[0079] In addition to the embodiment, the cross section and material can also be customized as needed to meet the stress requirements.

[0080] The purlin 4 is arranged above the main beam 3 and arranged longitudinally along the main beam 3, and the arrangement spacing is matched with the size of the upper photovoltaic panel.

[0081] In the embodiment, the main beam 3 is made of a square steel.

[0082] In addition to the embodiment, the cross section and material can also be customized as needed to meet the stress requirements.

[0083] In the embodiment, the purlin 4 and the main beam 3 are connected together through a U-shaped hoop 9.

[0084] In addition to the embodiment, the shape and material can also be customized as needed to meet the connection requirements.

[0085] The flat single-axis tracking support is equipped with a photovoltaic tracking control system, sensors, etc. according to the use requirements.

[0086] The photovoltaic tracking control system and the sensors are all 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.

[0087] In use, according to the instructions issued by the sun tracking control system (such as a control strategy based on time, light sensors, or a combination of both), the self-locking reduction motor 54 is started, and the rotating power of the self-locking reduction motor 54 is transmitted to the drive sprocket 56 through transmission connection, and the drive sprocket 56 starts to rotate.

[0088] With the rotation of the drive sprocket 56, since it is engaged with one of the rigid chains 52, the rigid chain 52 starts to slide in the rigid chain 52 slot, and since the two rigid chains 52 are mutually engaged, the other rigid chain 52 also moves synchronously, and the free end of the rigid chain 52 passes out of the chain storage shell 51, and its connected push-pull head 53 moves with the movement of the rigid chain 52, since the push-pull head 53 is hinged to the swing arm assembly 6, the movement of the push-pull head 53 drives the swing arm assembly 6 to swing.

[0089] Subsequently, the swing of the swing arm assembly 6 exerts a force on the main beam 3, and through the coordinated action of the mounting assembly 7 and the swing arm assembly 6, the main beam 3 rotates around the bearing assembly 2 at the top of the column 1.

[0090] Then, while the main beam 3 rotates, the purlin 4 and the photovoltaic panel mounted on the main beam 3 change the angle, so that the orientation of the photovoltaic panel is adjusted to better align with the sun and improve the efficiency of receiving solar energy.

[0091] During the continuous change of the sun position, the control system continuously sends instructions to the self-locking reduction motor 54 according to the preset strategy (such as timing adjustment, real-time light intensity monitoring adjustment, etc.), the self-locking reduction motor 54 changes the speed, direction, or start-stop state according to the instructions, and repeats the above steps, so that the main beam 3 and the photovoltaic panel continuously track the change of the sun position and always maintain the best angle to receive solar energy.

[0092] Finally, when the sun sets, the light intensity is lower than the set threshold, or other preset stop conditions are met, the control system issues an instruction, and the self-locking reduction motor 54 stops running, and the flat single-axis tracking support stops at the current position, waiting for the next start instruction.

[0093] During the entire operation process, the equipment is regularly inspected and maintained to ensure that all components are working properly.

[0094] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
