Description

Technical Field

[0001] The present application relates to the technical field of building roofs, and in particular to an ecological self-circulating photovoltaic green building roof and a construction method thereof. Background Art

[0002] Photovoltaic roof is a solar photovoltaic power generation system installed on the roof of a building. The core part of a photovoltaic roof is the photovoltaic module, which is usually made of materials such as monocrystalline silicon or polycrystalline silicon. These photovoltaic modules can convert solar energy into direct current. Its appearance is generally a dark blue or black rectangular plate with a certain thickness and weight. Photovoltaic modules of different specifications vary in size and power output, and can be selected and installed in combination according to the area of ​​the roof and actual needs.

[0003] Roof greening is planting vegetation on the roof. Roof greening can improve air quality. Both green roofs and photovoltaic roofs are ways to make buildings more green. Photovoltaic roofs are built by setting a support frame on the roof, then fixing the photovoltaic panels on the support frame, and planting vegetation next to the support frame.

[0004] The photovoltaic panels on the roof are related to the duration and angle of sunlight exposure, while conventional photovoltaic panels are directly fixed to the support frame. When the sun moves, the sunlight shining on the photovoltaic panels will be weakened, resulting in low energy efficiency. Summary of the invention

[0005] In order to improve energy utilization efficiency, the present application provides an ecological self-circulating photovoltaic green building roof and a construction method thereof.

[0006] In the first aspect, the present application provides an ecological self-circulating photovoltaic green building roof, which adopts the following technical solutions: An ecological self-circulating photovoltaic green building roof includes a photovoltaic panel, a carrier plate, an auxiliary support leg, a column and a rotating column.

The auxiliary support leg is an auxiliary support leg supported by a telescopic rod; the rotating column is provided with a driving component for driving the rotating column to rotate.

[0007] By adopting the above technical solution, as the sun rises from the east and sets in the west, the driving component causes the rotating column to rotate relative to the column, and the rotating column drives the carrier plate to swing, thereby finally realizing the change of the posture of the photovoltaic panel and extending the time that the photovoltaic panel is exposed to sunlight. The setting of multiple auxiliary legs ensures the stable placement of the carrier plate, and the photovoltaic panel swings as the sun moves, thereby improving energy utilization efficiency.
