Description

Technical Field

[0001] This invention relates to the field of photovoltaic project construction technology, and particularly to the field of photovoltaic bracket installation technology, specifically a photovoltaic bracket installation device. Background Technology

[0002] In recent years, with the deepening of the national "dual-carbon" strategic goals and the successive issuance of relevant policy documents by departments such as the Ministry of Housing and Urban-Rural Development and the National Energy Administration, the photovoltaic power generation industry has ushered in a period of rapid development. National and local governments have continuously released and updated relevant design specifications, construction safety standards, and industry support policies, vigorously promoting photovoltaic power generation, especially the large-scale and standardized construction of distributed photovoltaic projects.

[0003] In large-scale ground-mounted power plants, commercial and industrial rooftop photovoltaic projects, and complex mountain photovoltaic projects, photovoltaic support brackets, as the core structure supporting photovoltaic modules, are crucial for ensuring the quality, progress, and cost control of the power plant through efficient, precise, and safe installation. However, in the actual installation and construction of photovoltaic support brackets, especially in complex terrain (such as sloping roofs and rugged mountains) or high-altitude operation scenarios, the current mainstream photovoltaic support bracket installation mainly relies on manual handling combined with hoisting equipment, which presents significant technical bottlenecks.

[0004] Photovoltaic support structures are typically heavy and long, making their on-site transport and installation highly dependent on heavy lifting equipment such as cranes. Frequent crane scheduling, waiting, and coordination not only significantly increase construction costs but also make installation difficult due to site limitations. When working at heights, the safety railings on traditional work platforms are often inadequate or unstable, and the limited platform space hinders workers from carrying tools and materials flexibly, while also posing risks of personnel falls and materials falling.

[0005] Therefore, developing a photovoltaic support installation device that is highly adaptable to terrain, safe and stable, easy to operate and move, and can effectively reduce reliance on heavy hoisting equipment is of great practical significance and broad engineering application value for significantly improving the efficiency, accuracy and safety of photovoltaic support installation, reducing overall construction costs (especially machinery rental costs), and responding to the national requirements for safe and efficient new energy construction.
