Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic mounting brackets, and in particular to a dual-axis tracking photovoltaic panel bracket. Background Art

[0002] As an important device for converting solar energy into electrical energy, the power generation efficiency of solar photovoltaic panels is directly related to the economy and practicality of the entire solar power generation system. As an important supporting structure of photovoltaic panels, the design of photovoltaic panel brackets directly affects the efficiency and stability of photovoltaic systems.

[0003] The photovoltaic panel brackets currently on the market are mainly divided into two categories: fixed brackets and tracking brackets.

[0004] In the related art, the fixed photovoltaic panel bracket is fixed at a specific angle after installation and cannot be adjusted according to the position of sunlight. Although this type of bracket has a simple structure and low cost, it cannot adjust the angle of the photovoltaic panel as the position of the sun changes. As a result, the photovoltaic panel cannot always face the sun at different times and seasons, so the power generation efficiency is relatively low. Especially in areas of different geographical latitudes, due to the different angles of sunlight, fixed brackets cannot achieve the best photovoltaic power generation effect. In addition, in order to obtain more sunshine time, fixed brackets often require a larger floor space, which not only increases the installation cost, but is also an obvious disadvantage for application scenarios with limited space.

[0005] In some related technologies, compared with fixed brackets, dual-axis tracking photovoltaic panel brackets can adjust the angle of photovoltaic panels as the position of the sun changes, thereby maximizing the efficiency of photovoltaic power generation. This bracket can be adjusted in both vertical and horizontal directions to ensure that the photovoltaic panels are always facing the sun, significantly increasing the power generation per unit area. However, most of the existing dual-axis tracking photovoltaic panel brackets have a relatively complex structure. For example, in some related technologies, the bracket uses a large amount of metal materials, the overall weight is large, and it is not convenient to transport and install. In addition, the overall integrated design adopts welding technology, which requires professional welding personnel to operate, increasing the manufacturing cost. In addition, it is difficult for users to carry out personalized transformation or upgrade according to actual needs, which increases the difficulty of maintenance.

[0006] In summary, although the dual-axis tracking photovoltaic panel bracket has significant advantages over the fixed bracket in terms of power generation efficiency, its structural complexity, weight, manufacturing cost and maintenance difficulty still need to be improved, and it is difficult to meet market demand. Therefore, it is necessary to develop a dual-axis tracking photovoltaic panel bracket with simple structure, light weight, easy installation and maintenance, support for personalized upgrades and high production efficiency.

[0034] As an important device for converting solar energy into electrical energy, the power generation efficiency of solar photovoltaic panels is directly related to the economy and practicality of the entire solar power generation system. As an important supporting structure of photovoltaic panels, the design of photovoltaic panel brackets directly affects the efficiency and stability of photovoltaic systems.

[0035] The photovoltaic panel brackets currently on the market are mainly divided into two categories: fixed brackets and tracking brackets.

[0036] In the related art, the fixed photovoltaic panel bracket is fixed at a specific angle after installation and cannot be adjusted according to the position of sunlight. Although this type of bracket has a simple structure and low cost, it cannot adjust the angle of the photovoltaic panel as the position of the sun changes. As a result, the photovoltaic panel cannot always face the sun at different times and seasons, so the power generation efficiency is relatively low. Especially in areas of different geographical latitudes, due to the different angles of sunlight, fixed brackets cannot achieve the best photovoltaic power generation effect. In addition, in order to obtain more sunshine time, fixed brackets often require a larger floor space, which not only increases the installation cost, but is also an obvious disadvantage for application scenarios with limited space.

[0037] In some related technologies, compared with fixed brackets, dual-axis tracking photovoltaic panel brackets can adjust the angle of photovoltaic panels as the position of the sun changes, thereby maximizing the efficiency of photovoltaic power generation. This bracket can be adjusted in both vertical and horizontal directions to ensure that the photovoltaic panels are always facing the sun, significantly increasing the power generation per unit area. However, most of the existing dual-axis tracking photovoltaic panel brackets have a relatively complex structure. For example, in some related technologies, the bracket uses a large amount of metal materials, the overall weight is large, and it is not convenient to transport and install. In addition, the overall integrated design adopts welding technology, which requires professional welding personnel to operate, increasing the manufacturing cost. In addition, it is difficult for users to carry out personalized transformation or upgrade according to actual needs, which increases the difficulty of maintenance.

[0038] In summary, although the dual-axis tracking photovoltaic panel bracket has significant advantages over the fixed bracket in terms of power generation efficiency, its structural complexity, weight, manufacturing cost and maintenance difficulty still need to be improved, and it is difficult to meet market demand. Therefore, it is necessary to develop a dual-axis tracking photovoltaic panel bracket with simple structure, light weight, easy installation and maintenance, support for personalized upgrades and high production efficiency.

[0039] For this reason, Figures 1 to 4 As shown, the dual-axis tracking photovoltaic panel support proposed by the present invention includes a first support 100, a rotating assembly 200, a connecting bracket 300 and an electric push rod 400, wherein the connecting bracket 300 is used to install the photovoltaic panel 500, the electric push rod 400 is used to drive the connecting bracket 300 to tilt, and the rotating assembly 200 is used to drive the connecting bracket 300 to rotate circumferentially. Specifically, the rotating assembly 200 is connected to the top of the first support 100, and the rotating assembly 200 includes a driving assembly 210 and a second support 220, and the driving assembly 210 is connected to and drives the second support 220 to rotate circumferentially. In addition, the connecting bracket 300 is connected to the top of the second support 220 and slides with the second support 220. In addition, the two ends of the electric push rod 400 are respectively hinged with the second support 220 and the connecting bracket 300, and the electric push rod 400, the second support 220 and the connecting bracket 300 form a triangular structure, and the electric push rod 400 is used to drive the connecting bracket 300 to tilt and form an angle with the horizontal plane. It should be noted that the driving assembly 210 can adjust the rotation angle of the second support 220, and then adjust the azimuth of the photovoltaic panel 500 through the connecting bracket 300, which solves the problem that the fixed mounting bracket is difficult to adjust the azimuth direction of the photovoltaic panel 500, so that the photovoltaic panel 500 can be adjusted with the change of the position of the sun, and the photovoltaic power generation efficiency is maximized. In addition, the triangular structure formed by the electric push rod 400, the second support 220 and the connecting bracket 300 has high stability and simple structure. Under the push of the electric push rod 400, the inclination of the photovoltaic panel 500 can be adjusted. The operation is simple and flexible, and the inclination of the photovoltaic panel 500 can be easily adjusted to ensure that the photovoltaic panel 500 always maintains the optimal angle to receive sunlight, which significantly improves the tracking accuracy and power generation efficiency of the photovoltaic panel 500.

[0040] Refer to Figure 1 and Figure 2In some embodiments of the present invention, the driving assembly 210 includes a driving motor 211 and a gear pair, and the driving motor 211 and the second support 220 are driven by the gear pair to achieve precise control of the azimuth angle of the photovoltaic panel 500. It is easy to understand that the gear pair plays the role of speed reduction transmission, improves the stability and accuracy of rotation, reduces the load of the motor, and prolongs the service life. Specifically, the gear pair includes a driving gear 2111 and a slewing bearing 2112, wherein the driving gear 2111 is fixedly connected to the driving shaft of the driving motor 211, and the slewing bearing 2112 includes an inner ring 21121 and an outer ring 21122 that rotate with each other, wherein the outer ring 21122 is fixedly connected to the first support 100, and the second support 220 is fixedly connected to the inner ring 21121, and the driving gear 2111 and the outer ring 21122 are meshed and driven to drive the second support 220 and the inner ring 21121 to rotate together around the center line of the outer ring 21122, thereby achieving stable rotation of the second support 220 and the inner ring 21121 around the center line of the outer ring 21122. It should be noted that the slewing bearing 2112 can withstand large radial loads, axial loads and overturning moments, and is suitable for applications such as photovoltaic panel 500 brackets that need to carry heavy objects and need to rotate. Moreover, compared with the traditional bearing combination, the slewing bearing 2112 integrates the inner and outer rings and the raceway, and has a more compact structure, which helps to reduce the size and weight of the overall bracket. In addition, the slewing bearing 2112 is usually designed as an integral unit, which is easy to install and disassemble, reduces the difficulty and cost of maintenance, and is usually equipped with a good sealing system to prevent dust and water from entering the slewing bearing 2112, prolong the service life of the slewing bearing 2112, and improve the reliability of the system. Therefore, the selection of the slewing bearing 2112 not only ensures the smoothness and accuracy of the rotation, reduces wear, improves the reliability of the overall structure, but also improves the reliability and durability of the entire system, and reduces maintenance costs. Optionally, the second support 220 is connected to a protective baffle 230, which is arranged around the gear pair, effectively protecting the internal gear pair from the influence of the external environment, prolonging the service life of the equipment, and reducing the number of maintenance times.

[0041] Refer to Figure 3 and Figure 4In some embodiments of the present invention, the connecting bracket 300 includes a plurality of first beams 310 and a plurality of second beams 320, and the first beams 310 and the second beams 320 are arranged vertically and horizontally and fixed by splicing through the first standard angle connector (not shown in the figure). Further, the first support 100 is fixedly connected to the first connecting plate group 110 through the second standard angle connector 111, and the outer gear ring 21122 is fixedly connected to the first connecting plate group 110 by screws; the second support 220 is fixedly connected to the second connecting plate group 221 through the third standard angle connector 222, and the inner ring 21121 is fixedly connected to the second connecting plate group 221 by screws. In addition, a base 120 is provided at the bottom of the first support 100, and the bottom of the first support 100 is fixedly connected to the base 120 by the fourth standard angle connector 121. This modular design makes installation and maintenance easier, and is also convenient for expansion or adjustment according to actual needs. Common first standard angle connectors include angle steel and angle code. Further, in some embodiments of the present invention, a connecting beam 240 is installed on the top of the second support 220, and optionally, the second support 220 and the connecting beam 240 are fixedly connected by a fifth standard corner joint 241. In addition, the connecting beam 240 is installed with a plurality of supporting blocks 250, and the supporting blocks 250 correspond to the first beam 310 one by one. The first beam 310 is provided with a sliding groove 31101, and the supporting blocks 250 are installed with positioning pins 260, which are inserted into the sliding groove 31101 and slidably cooperate with the sliding groove 31101 to drive the connecting bracket 300 to tilt around the center line of the positioning pin 260, thereby realizing the flexible adjustment of the tilt angle of the photovoltaic panel 500 and improving the power generation efficiency. Specifically, there are multiple sliding grooves 31101, and the multiple sliding grooves 31101 are arranged at intervals along the length direction of the first crossbeam 310. The positioning pin 260 slides with one of the sliding grooves 31101, so that the connecting bracket 300 can adjust the inclination angle at multiple positions, which enhances the adaptability and flexibility of the system. Further, the support block 250 includes a first support block 251 and a second support block 252, and the first support block 251 and the second support block 252 are arranged opposite to each other. Optionally, the first support block 251 and the second support block 252 are both standard corner joints. The first crossbeam 310 includes a limiting portion 311, and the limiting portion 311 is placed between the first support block 251 and the second support block 252. In addition, the structural stability of the connecting bracket 300 is improved, ensuring that the photovoltaic panel 500 can maintain good stability under various conditions. For example, multiple sliding grooves 31101 are arranged at intervals on the limiting portion 311 along the length direction of the limiting portion 311, further improving the flexibility of the initial installation position of the connecting crossbeam 240 and the connecting bracket 300.Optionally, the first crossbeam 310 and the second crossbeam 320 are both L-shaped steel. On the one hand, the first crossbeam 310 and the second crossbeam 320 are connected by a standard first standard angle joint, which does not require professional operation, reduces the technical threshold of installation, and can achieve simple and fast assembly, reducing installation costs and time. On the other hand, the first crossbeam 310 and the second crossbeam 320 of L-shaped steel not only ensure sufficient structural strength, but also achieve lightweight design, which is easy to transport and install.

[0042] In addition, in some embodiments of the present invention, in reference to Figure 3 and Figure 4 , the side wall of the second support 220 is adjustable with a first mounting seat 410 in a direction parallel to the center line of the second support 220, the bottom of the connecting bracket 300 is adjustable with a second mounting seat 420 in a linear direction, the electric push rod 400 is rotatably mounted on the first mounting seat 410, and the driving shaft of the electric push rod 400 is hinged with the second mounting seat 420. It is easy to understand that by installing the first mounting seat 410 and the second mounting seat 420 with adjustable positions on the side wall of the second support 220 and the bottom of the connecting bracket 300, the position of the electric push rod 400 is flexibly adjusted, the accuracy and flexibility of the inclination adjustment of the photovoltaic panel 500 are further improved, and the adaptability of the system is enhanced. Specifically, the side wall of the second support 220 is provided with a vertical fixing groove 2201 extending parallel to the center line direction of the second support 220, and the first mounting seat 410 is fixed to any height position of the vertical fixing groove 2201 by screws. In addition, the first crossbeam 310 is L-shaped steel, and the first crossbeam 310 also includes a connecting portion 312 integrally connected to the limiting portion 311. The connecting portion 312 is arranged vertically to the limiting portion 311 and forms an L-shaped structure. Similar to the sliding groove 31101, the connecting portion 312 has a plurality of mounting slot holes 3121 arranged at intervals along the length direction, and the second mounting seat 420 is fixed in one of the mounting slot holes 3121 by screws.

[0043] It should be further emphasized that most of the photovoltaic panel connection bracket parts connected to the photovoltaic panels in the prior art are welded with steel structures, which are not removable and have high requirements for welding technology, which increases the manufacturing cost and requires professional welding personnel, increasing the cost and difficulty of installation and maintenance. In the present application, angle steel or angle code is used between the first support 100 and the base 120, between the second support 220 and the connecting beam 240, and between the first beam 310 and the second beam 320, and connected by bolts and nuts. By reducing the amount of welding of the connecting bracket 300, the packaging and transportation process is greatly simplified, and a convenient on-site assembly method is provided, which effectively improves the installation efficiency, reduces the construction cost, and significantly increases the cost performance of the connecting bracket 300.

[0044] According to the above description, the dual-axis tracking photovoltaic panel bracket adopts a modular design. It is assembled by using industrial standard parts, has strong compatibility, can reduce the manufacturing time of custom parts in the production process, shorten the production cycle, and improve production efficiency. In this regard, standard parts are easy to obtain and replace, and repair and maintenance are more convenient, which reduces maintenance costs and repair time. It can be quickly connected by standard fasteners, without welding, drilling and other processes, simplifying the manufacturing and installation process. In addition, the modular design provides space for personalized upgrades and modifications, and the product components are standardized, making updates and upgrades more convenient, and can adapt to market changes and technological progress more quickly. In addition, users can also replace or add different functional modules according to their needs to improve the flexibility and adaptability of the system. Further, the drive motor 211 using a closed-loop control method, for example, the drive motor 211 is a servo motor, which can improve the overall anti-interference of the product and further improve the accuracy of the product; at the same time, it can well suppress the overshoot and oscillation caused by the stepping error caused by the external force when the conventional stepping motor moves, reduce the energy loss caused by these phenomena, and respond to the drive requirements more quickly, reducing the generation of energy consumption.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
