Modularization and innovation connection: technological innovation of aluminum alloy ground photovoltaic bracket system

1. Modular design: simplifying the manufacturing and installation process

The modular design concept of the aluminum alloy ground photovoltaic bracket system breaks the inherent mode of integrated manufacturing of traditional brackets and disassembles the bracket structure into multiple standardized and interchangeable independent modules. In the production and manufacturing process, this design greatly improves production efficiency. Each module can be produced through large-scale assembly lines in the factory to achieve professional and refined processing. The columns, beams, diagonal braces and other components of the bracket can be mass-produced according to unified standards and specifications, which reduces the debugging and adjustment time in the production process and reduces production costs.

From the installation perspective, modular design makes on-site construction more convenient and efficient. Traditional steel brackets often require a lot of on-site welding and cutting work during installation, which is not only difficult to construct, but also easily affected by external factors such as weather. After the modular components of the aluminum alloy bracket are transported to the construction site, workers only need to follow the design drawings and use special tools to quickly complete the assembly. This "building blocks" installation method greatly shortens the construction period. Even in complex terrain or harsh environments, the installation task can be completed efficiently, reducing the manpower and time costs during the installation process. The modular design also facilitates later maintenance and upgrades. When a module is damaged or needs to be replaced, only the corresponding part needs to be disassembled for replacement, without large-scale changes to the entire bracket system, effectively reducing the difficulty and cost of maintenance. ​
2. Special connectors: Advantages of innovative connection methods ​
The aluminum alloy ground photovoltaic bracket system abandons the commonly used welding connection method of steel and instead adopts a variety of special connectors such as bolt connection and snap connection. This change brings many significant advantages. ​
(I) Avoid thermal deformation and performance changes ​
The high temperature generated during the welding process will change the organizational structure of the steel, resulting in local thermal deformation, affecting the dimensional accuracy and overall structural stability of the bracket. The special connectors used in the aluminum alloy bracket do not require high-temperature operation during the connection process, which fundamentally avoids the problem of thermal deformation. Taking bolt connection as an example, through the precisely designed bolt hole position and appropriate bolt specifications, the various components can be firmly connected together, while ensuring the dimensional accuracy and structural integrity of the bracket. The snap-on connection utilizes the good elasticity and toughness of aluminum alloy itself, and through ingenious structural design, it realizes fast and tight connection between components. It also does not affect the organizational properties of aluminum alloy materials, ensuring the stability and reliability of the bracket during long-term use. ​
(II) Enhanced connection flexibility and adjustability ​
Specialized connectors give aluminum alloy brackets stronger connection flexibility and adjustability. In different application scenarios, photovoltaic brackets may need to adapt to different installation angles, terrain conditions and load requirements. Bolt connection can achieve fine-tuning of the angle and distance between bracket components by adjusting the tightening degree and connection position of the bolts to meet the optimal installation requirements of photovoltaic panels under different lighting conditions. The snap-on connection is convenient for temporary adjustment or rearrangement of the bracket structure according to actual conditions during installation due to its quick disassembly and assembly characteristics. This flexibility and adjustability enable aluminum alloy brackets to better adapt to diverse installation environments and improve the overall performance and power generation efficiency of photovoltaic systems. ​
(III) Improve structural reliability and durability ​
High-quality special connectors have been rigorously designed and tested to provide reliable connection strength and durability for aluminum alloy brackets. After selecting the appropriate material and specifications, the bolt connection can withstand large tensile and shear forces, ensuring that the bracket remains stable under various external forces. The snap connection can disperse the effect of external forces on the connection parts while ensuring a tight connection through reasonable mechanical structure design, reduce local stress concentration, and extend the service life of the bracket. Some special connectors also use special anti-corrosion treatment, which matches the corrosion resistance of the aluminum alloy bracket, further enhancing the durability of the entire bracket system in complex outdoor environments and reducing safety hazards and maintenance costs caused by damage to the connectors. ​
3. Application scenarios: The value of modularization and innovative connections ​
In application scenarios such as ground photovoltaic power stations and concrete flat roof photovoltaic power stations, the modular design and special connector advantages of aluminum alloy brackets are fully reflected. ​
In the construction of ground photovoltaic power stations, especially in areas with complex terrain, such as mountainous and hilly areas, modular design enables the bracket to better adapt to irregular terrain. Construction personnel can flexibly adjust the combination and installation angle of the modules according to the characteristics of the on-site terrain to ensure that the photovoltaic panels can receive sunlight in the best posture. The convenient installation characteristics of special connectors also make the construction process more efficient and reduce the difficulty and risk of construction in complex terrain. The modular structural design also facilitates the expansion and transformation of the power station in the later stage. The scale of the power station can be expanded by adding corresponding modules, which improves the flexibility and sustainability of power station construction. ​
For concrete flat roof photovoltaic power stations, the lightweight and modular design of aluminum alloy brackets effectively reduce the bearing pressure of the roof. The use of special connectors avoids complex operations such as welding on the roof, reduces the risk of damage to the roof structure, and ensures the safety of the building. During the installation process, construction personnel can flexibly choose the appropriate installation method and module combination according to the shape, area and bearing capacity of the roof, and make full use of the roof space to achieve efficient power generation. In the later maintenance, the modular structure and the convenient disassembly characteristics of special connectors make the maintenance work easier and more efficient, and can quickly locate and solve problems, ensuring the long-term and stable operation of the photovoltaic system. ​
The modular design and application of special connectors of the aluminum alloy ground photovoltaic bracket system are an important innovation in the development of photovoltaic bracket technology. This innovation not only improves the performance and reliability of the bracket system, simplifies the manufacturing and installation process, but also provides strong support for the development of the photovoltaic industry in different application scenarios. With the continuous advancement of technology and the accumulation of application experience, the modularization and innovative connection technology of aluminum alloy brackets are expected to be further optimized, playing a greater role in the sustainable development of the solar photovoltaic industry.
