Description

Technical Field

[0001] The utility model belongs to the technical field of solar photovoltaic, and particularly relates to a roof solar photovoltaic system with a daylighting belt. Background Art

[0002] A solar photovoltaic system, also known as photovoltaic effect, abbreviated as PV, refers to a facility that converts solar energy into direct current electricity by using the photovoltaic effect of photovoltaic semiconductor materials. The core of the photovoltaic facility is a solar panel.

[0003] At present, a Chinese patent with the publication number CN207974400U and the publication date of October 16, 2018 discloses a factory building roof installed with solar panels, which has a gable roof. There is a drainage ditch at the bottom of the slope of the gable roof. Solar panels are installed on the sunny side of the gable roof, and there is also a transverse maintenance walkway. There are multiple gable roofs on the entire factory building roof. The gable roof on the sunny side serves as the base of the solar panel matrix. The shady side of the gable roof and the drainage ditch are arranged between two rows of bases. The lower half of the shady side of the gable roof facing the sunny side of another gable roof is a movable roof. The transverse maintenance walkway is arranged below the movable roof.

[0004] By installing solar panels on the sunny side of the gable roof, the solar panels are used to convert solar energy into electricity for use in the factory building below. However, after the solar panels are laid on the sunny side of the gable roof, the densely spliced solar panels will block the sunlight during the day, which is not conducive to the lighting in the factory building below. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a roof solar photovoltaic system with a daylighting belt, which can conveniently provide relatively sufficient lighting below.

[0006] The above technical object of the utility model is achieved by the following technical solutions: A roof solar photovoltaic system with a daylighting belt, which includes a solar photovoltaic panel group located above the roof and in a herringbone slope shape, and a bracket located below the solar photovoltaic panel group. The solar photovoltaic panel group includes two rows of first solar photovoltaic panels located on one side above the roof, a first daylighting glass plate located between the two rows of first solar photovoltaic panels, two rows of second solar photovoltaic panels located on the side of the roof above and far from the first solar photovoltaic panels, a second daylighting glass plate located between the two rows of second solar photovoltaic panels, and a third daylighting glass plate located at the middle position above the roof and between the first solar photovoltaic panels and the second solar photovoltaic panels. Both the first solar photovoltaic panel and the second solar photovoltaic panel include multiple solar panels spliced together. The first daylighting glass plate, the second daylighting glass plate, and the third daylighting glass plate all include multiple light-transmitting glass plates spliced together. On the side of the solar panel close to the light-transmitting glass plate, there is a support arm with one end connected to the solar panel and the other end supported on the lower surface of the light-transmitting glass plate. A sealant layer is filled between the light-transmitting glass plate and the solar panel.

[0007] The further setting of the utility model is: The bracket includes multiple support keels in a V shape with an open bottom located on the lower surface of the solar photovoltaic panel group, and columns arranged at both ends of the support keels and extending in the vertically downward direction.

[0008] The further setting of the utility model is: A cross beam is arranged below the support keel, with both ends respectively connected to the columns on both sides. Multiple connecting rods connected to the support keels are arranged on the cross beam.

[0009] The further setting of the utility model is: There are four connecting rods, which are respectively located at the positions below the two first solar photovoltaic panels and the two second solar photovoltaic panels.

[0010] The further setting of the utility model is: A support plate connected to the ground is arranged at the lower end of the column.

[0011] The further setting of the utility model is: U-shaped steel bars embedded in the ground concrete layer are arranged on both sides of the support plate. Through holes for the ends of the steel bars to pass through are opened on the support plate. Threaded ends are arranged at both ends of the steel bars, and locking nuts tightened against the support plate are threadedly connected to the threaded ends.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. By using a first daylighting glass plate located between two rows of first solar photovoltaic panels, a second daylighting glass plate located between two rows of second solar photovoltaic panels, and a third daylighting glass plate located between the first solar photovoltaic panels and the second solar photovoltaic panels, the first daylighting glass plate, the second daylighting glass plate, and the third daylighting glass plate can allow light to shine in, thus facilitating the provision of relatively sufficient lighting below; among them, the solar panels are supported on the lower surface of the transparent glass plate by support arms, thereby playing a role in supporting the transparent glass plate between two adjacent solar panels. At the same time, by using a sealant layer filled between the transparent glass plate and the solar panel, the sealant layer can seal the installation gap between the transparent glass plate and the solar panel, which is beneficial to reducing the possibility of water leakage and is also conducive to the stable splicing between the transparent glass plate and the solar panel;

[0014] 2. By using support keels to support at the lower surface of the solar photovoltaic panel group and using columns to support on the ground at the same time, the solar photovoltaic panel group can be stably supported at this time;

[0015] 3. By connecting the two ends of the cross beam to the columns on both sides respectively, and then connecting the connecting rod to the support keel on the cross beam, the support keel can be further supported by the cross beam and the connecting rod at this time, which is beneficial to stably and reliably support the solar photovoltaic panel group;

[0016] 4. By using four connecting rods and arranging them at the positions corresponding to the lower sides of two first solar photovoltaic panels and two second solar photovoltaic panels respectively, the connecting rods can support the positions of the first solar photovoltaic panels and the second solar photovoltaic panels at this time, which is beneficial to supporting and protecting the heavier first solar photovoltaic panels and second solar photovoltaic panels; at the same time, the connecting rods can also avoid the positions of the first daylighting glass plate, the second daylighting glass plate, and the third daylighting glass plate, avoiding the influence of the connecting rods on the light;

[0017] 5. The column can be stably supported on the ground by using the support plate;

[0018] 6. When the support plate supports on the ground, a U-shaped steel bar is embedded in the concrete layer of the ground, and then a locking nut is threadedly connected to the threaded end of the steel bar end. Finally, the column can be stably supported on the ground through the support plate and the steel bar. BRIEF DESCRIPTION OF THE DRAWINGS
