In this embodiment, the number of panels 40 of the ventilation unit is 6, and the corresponding photovoltaic glass panels 7 are connected in series with each other through cables.

[0026] The end of the second side keel 45 is connected to a decorative strip 8.

[0027] like Figure 1 、 Figure 2 As shown, to prevent rainwater from entering the room through the ventilation unit, a first annular drain ditch 91 is provided on the outside of the ceiling steel frame 2 at the lower edge of the ceiling 3. This first drain ditch 91 has a C-shaped longitudinal section and is fixedly connected to the ceiling steel frame 3 on the inside. A grate 92 is provided at the outer opening, and a drainage pipe 93 is provided at the bottom. Rainwater flowing down from the ceiling 3 flows into the first drain ditch 91 through the grate 92 and is then discharged from the drainage pipe 93 at the bottom.

[0028] The construction process of the present invention is as follows:

[0029] 1. Complete the main structure of the stadium, then set up the roof steel frame on the top of the main structure, install the curtain wall on the outside of the main structure, and set up the roof on the top of the roof steel frame.

[0030] 2. Install the photovoltaic ventilation wing system. The first main keel, second main keel, secondary keel, first side keel, and second side keel are processed and welded together in the factory, with high precision and fast construction progress. The gusset plate and decorative strip are installed at the ends of the first side keel and the second side keel respectively through the angle bracket, which is adjustable and has high precision.

[0031] 3. Install the bottom aluminum plate to cover each keel;

[0032] 4. Customized frameless double-glass photovoltaic glass panels, with colored glaze treatment on the outer glass, 5BB layout of crystalline silicon cells, hidden solder ribbons and busbars, and factory-assembled, precision-machined aluminum alloy sub-frames based on the practice of hidden-frame glass curtain walls;

[0033] 5. Finally, install the top aluminum plate and photovoltaic glass panel (after framing), apply glue and seal, and fix six panels into a group on two parallel inclined beams, and then install the entire structure on the outside of the ceiling steel frame;

[0034] 6. Install the first drainage ditch on the ceiling steel frame at the lower edge of the ceiling and the second drainage ditch on the top of the main structure.

[0035] The advantages of the present invention are as follows:

[0036] 1.

[0037] 2. The photovoltaic ventilation wing system has a unified effect and is beautiful (custom aluminum profiles are used at the front and rear of the structure to ensure flatness; the outer glass of the photovoltaic module is glazed with the same color as the adjacent metal, lined with black film, and the crystalline silicon cell welding ribbons and bus bars are hidden; the electrical wiring is also hidden);

[0038] 3. The photovoltaic ventilation wing system is safe and reliable, and improves power generation efficiency (same as the trough principle, the finished surface of the photovoltaic module is slightly lower than the adjacent aluminum plate and aluminum profile, and the outer surface of the photovoltaic module is unobstructed, reducing dust accumulation).
