[0002] With the development of the renovation of old urban buildings, it is often necessary to install photovoltaic modules on the roofs after renovation to reduce building energy consumption. This is because there is little light obstruction above the building roofs, which is very suitable for the continuous installation of photovoltaic modules. At present, the photovoltaic installation after the building roof renovation mainly adopts flat photovoltaic, but the building renovation also needs to adapt to the aesthetic requirements of the building's facade, especially for old large-span public buildings. Therefore, there has been an engineering and technical demand for installing sloped photovoltaic modules after the building roof renovation.

[0003] In the above working conditions, the photovoltaic support structure needs to be set continuously and inclined, and the overall size of the photovoltaic module matrix is ​​large, the support structure components under the photovoltaic module are numerous, and the space is small. If a local photovoltaic module fails and needs to be damaged, it is difficult for personnel to enter from under the photovoltaic panel where the photovoltaic support structure is arranged to remove the photovoltaic module. At the same time, old buildings cannot bear heavy mechanical loads after renovation, and the sloped photovoltaic modules are large in size, which makes it difficult to meet the actual needs of personnel to replace the photovoltaic panels from above. Therefore, it is necessary to propose an easy-to-replace photovoltaic panel support structure for sloped photovoltaics after the building roof is renovated. Utility Model Content

[0036] Furthermore, the distance between the missing edge sealing member 10 and the bottom plate 11, and the distance between adjacent bottom plates 11 are greater than the width of the photovoltaic panel 2;

[0037] Furthermore, the area of ​​the photovoltaic support structure 3 where the quick-change device is not provided is provided with an I-shaped fixing groove 1 fixedly connected to the extension direction of the missing limb edge banding 10 and fixedly connected to the extension direction of the bottom plate 11; the splint 12 is a U-shaped groove structure, and its opening is greater than or equal to the thickness of the first limiting plate 22.
