I. Introduction

Against the backdrop of the continued growth of global solar installed capacity, the technological innovation of ground solar support systems has become the core driving force for improving the economy and reliability of power stations. The Steel Channel support system in the double-column ground solar support system launched by Haina solar uses Q235 hot-dip galvanized steel as the base material. Through the I-shaped cross-section design, anti-sinking base technology and modular construction process, a solution with high load-bearing capacity and adaptability to complex terrain has been constructed. This article will deeply analyze the technical principles, application scenarios and industry practices of the system, and reveal its key role in promoting the high-quality development of the solar industry.

2. Core technology analysis: structural design and material innovation

1.

Mechanical advantages of I-shaped sections

The Steel Channel bracket system uses Q235 hot-dip galvanized steel to form an I-shaped beam structure by optimizing the cross-sectional shape. Its mechanical properties have significant advantages:

2.

1. Improved bending strength: The neutral axis of the I-shaped section is located in the middle of the web, the upper flange bears compressive stress, and the lower flange bears tensile stress. The material properties are fully utilized, and the bending strength is increased by 30% compared with the traditional rectangular section.

2. Optimized torsional performance: The synergistic effect of the flange and the web effectively suppresses the torsional deformation of the bracket. Under strong wind conditions, the structural deformation is controlled within a very small range.

3. Lightweight design: Through finite element analysis to optimize material distribution, the unit weight bearing capacity is increased by 20%, achieving a reduction in material usage under the same load.

3.

Anti-settling base technology

For soft geological conditions, the Steel Channel bracket system innovatively adopts an anti-settling base design:

4.

1. Elastic support structure: The base has a built-in spring shock absorber, which can absorb most of the foundation settlement force and effectively reduce the risk of hidden cracks caused by uneven ground settlement.

2. Screw pile combination foundation: Combining screw piles with concrete prefabricated blocks, it can achieve rapid installation, suitable for complex geology such as frozen soil and sand, and significantly reduce the cost of land leveling.

3. Dynamic balance adjustment: Through the diamond jack and the synchronous connecting shaft, the dual-axis angle adjustment is achieved to reduce the component shielding loss caused by terrain undulations.

5.

Hot-dip galvanizing anti-corrosion system

The bracket adopts hot-dip galvanizing process (zinc layer thickness ≥ 85μm) to form a dense zinc-iron alloy coating, and its anti-corrosion performance has the following characteristics:

6.

1. Self-repair mechanism: When the coating is partially damaged, the zinc will dissolve to form a zinc oxide layer, which continues to protect the steel matrix and is suitable for high salt fog and strong corrosion environments.

2. Long-term protection: C4-C5 anti-corrosion grade steel can last for more than 25 years in harsh environments. With the intelligent reverse tracking algorithm, it can further reduce the loss of component shielding.

III. Application scenarios and technical advantages

1.

Adaptability to complex terrain

The Steel Channel bracket system can operate stably under various terrain conditions due to its structural design advantages:

1. Desert and soft geology: Through the design of sand-leaking bearings and efficient foundation solutions, the impact of wind and sand accumulation is reduced and the power generation efficiency is improved; the elastic support structure copes with foundation settlement and ensures the long-term reliability of the system.

2. Mountainous and hilly areas: Modular design and angle adjustment technology enable flexible deployment, significantly improve land utilization, and reduce the construction difficulty caused by complex terrain.

3. Coastal high-corrosion areas: High-grade anti-corrosion materials are combined with prestressed concrete foundations to resist salt spray erosion and ensure structural stability in extreme climates.

3.

Multi-scenario function expansion

In addition to the basic support function, the system can be combined with ecological governance, agricultural planting and other scenarios:

4.

1. solar sand control and ecological restoration: By raising the height of the bracket, space is provided for the growth of vegetation below, forming a three-dimensional mode of "power generation on the board and protection under the board", which helps the sustainable development of desertified areas.

2. Agricultural light complementarity and space utilization: The height of the bracket can be adapted to the needs of different crop planting or animal husbandry, achieving the compound benefits of "power generation + agriculture" and improving the comprehensive utilization rate of land.

IV. Installation and operation and maintenance optimization

Modular construction process

2.

1. Fast assembly: The use of standardized components and bolt connections greatly shortens the on-site construction time, and the efficiency is significantly improved compared with traditional welding processes.

2. Terrain adaptability: The single-column bracket system uses three-dimensional angle adjustment technology to flexibly adapt to different slopes and undulations, reducing the cost of initial terrain leveling.

3.

Intelligent operation and maintenance system

4.

1. Remote monitoring: Integrated intelligent monitoring platform, real-time tracking of bracket operation status, accurate positioning of faults and early warning, reducing the cost of manual inspections.

2. Automated collaboration: It can be linked with cleaning robots and meteorological monitoring equipment to optimize component angles and cleaning frequency through intelligent algorithms, improve power generation efficiency and reduce equipment loss.

V. Industry trends and future prospects

1.

Material revolution continues to advance

2.

1. High-performance coated steel: New materials such as galvanized aluminum and magnesium are gradually applied, and corrosion resistance is several times higher than traditional hot-dip galvanizing, adapting to more stringent environmental conditions.

2. Lightweight composite materials: The research and development of lightweight materials such as carbon fiber reinforced plastics is accelerated, and in the future, the weight of the bracket system can be greatly reduced, and carbon emissions can be significantly reduced.
