Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically referring to a green building energy-saving roof. Background Technology

[0002] In recent years, with the increasing severity of the global energy crisis and environmental problems, green building has gradually become a mainstream trend. Regarding building energy conservation, traditional flat roofs have been criticized for their poor thermal insulation and inadequate rainwater drainage, while pitched roofs have gained attention due to their excellent drainage and greater surface area utilization. However, current applications of pitched roofs are mostly limited to aesthetics, failing to fully utilize their potential for higher levels of energy harvesting and conversion. Furthermore, although solar energy, as a clean energy source, has been widely used in buildings, effectively integrating it into roofs still faces many challenges.

[0003] Currently, the industry has proposed various solutions to improve roof functionality. For example, the traditional method of installing fixed photovoltaic modules can generate a certain amount of electricity, but its practicality is limited due to the complexity of installation and the inconvenience of later maintenance. Another method is to reduce indoor temperature by adding a reflective coating to reduce heat absorption. Although this method is simple and easy to implement, it cannot take into account the power generation efficiency. There is also a form of using laminated glass with built-in thin-film batteries. Although this form ensures a certain degree of light transmission, it sacrifices cost control and long-term stability.

[0004] In summary, both traditional fixed photovoltaic panels and new embedded designs generally suffer from low flexibility, high construction difficulty, and cumbersome maintenance and replacement. Furthermore, they cannot fully adapt to the usage requirements under different climatic conditions, making it difficult to meet the demands of modern green buildings for high-efficiency comprehensive performance.

A fixing groove distributed along the long axis is opened at the center of the side of the base frame away from the sloping roof. The positioning component is arranged in an inverted U-shape inside the base frame. The buckle is arranged in a cross shape and clamps between two adjacent sets of solar panels. A bolt is fixedly connected from top to bottom between the center of the positioning component, the fixing groove, and the positioning component.

[0011] Preferably, the fixing assembly further includes a mounting side plate located outside the outermost solar panel. The mounting side plate is arranged in an inverted L-shape, and bolts are used to fix the mounting side plate and the positioning member.

[0012] Preferably, the diameter of the first bolt is equal to the gap between the adjacent solar panels.

[0013] Preferably, at least two sets of the base frame are provided below the solar panel to increase the stability of the connection.
