Description

Technical Field

[0001] This utility model relates to photovoltaic roofs, and more particularly to waterproof structures for photovoltaic roofs. Background Technology

[0002] Buildings, industry, and transportation are the three major energy consumers. Building energy consumption has already surpassed that of industry and transportation. Therefore, energy conservation and consumption reduction in buildings is an inevitable trend and a must.

[0003] Solar building applications are a key focus of energy conservation and emission reduction. The application of solar photovoltaic (PV) and solar thermal systems in buildings should be coordinated based on solar resource conditions, building utilization conditions, and energy demand, utilizing electricity where appropriate and thermal energy where appropriate. Existing solar buildings typically install photovoltaic modules on the roof envelope of existing corrugated steel roofs, a method known as "Building-in-Place Photovoltaic (BAPV) installation." This system consists of PV modules, purlin support systems, and inverter electrical systems, connected to the building's AC power distribution grid. It has a single power generation function and does not function as a building or building material. BAPV installation generally involves first fixing the PV modules to the corrugated steel roof using metal clamps and bolts. Metal purlins are then fixed to the clamps, and finally, metal blocks and bolts are used to secure and lock the PV modules onto the corrugated steel roof.

[0004] First, with this installation method, the photovoltaic modules on the corrugated steel roof are subjected to the pulling, stretching, and suction of wind over time. At the connection points between the metal clamps and the corrugated steel roof tiles, the corrugated steel tiles deform or even tear. During rain or snow, this leads to roof leaks, affecting the usability of the building space, causing property damage, and impacting the collection of photovoltaic electricity fees for the owner's portion. Second, this installation method also creates friction between the metal clamps and the corrugated steel roof tiles, damaging the waterproof and anti-corrosion coatings on the corrugated steel tiles. This accelerates rusting, aging, and oxidation, ultimately shortening the lifespan of the corrugated steel roof. Utility Model Content

[0020] This invention provides a sealed and waterproof structure for a photovoltaic roof. The vertical structure is fixed to the C-shaped steel purlins of the photovoltaic roof structure. The horizontal structure consists of two aluminum profiles clamped together and fixed to the photovoltaic module frame profile, serving both sealing and drainage functions. The longitudinal structure comprises two profile cross-section guide rails with adjustable tilt angles. Special clamp bolts are used to fix the photovoltaic module frame profiles onto these rails. Waterproof adhesive strips are used to fill the gaps. When water seeps through the gaps between the vertical modules, it flows away through the vertical drainage channel. When water seeps through the gaps between the horizontal modules, the lower end of the profile rests on the vertical drainage channel, allowing the seeping water to flow away.

[0021] The sealing strips are placed at the gaps in the component frame profiles to block most of the water flow, while a small amount of seepage is discharged through the water guide channel. Attached Figure Description
