Description

Technical Field

[0001] The utility model belongs to the technical field of solar photovoltaic development equipment, and in particular relates to a roof photovoltaic bracket which can be used on a concrete roof and can bear a relatively small load. Background Art

[0002] With the popularization of renewable energy, rooftop distributed photovoltaic systems are favored for their advantages of easy installation, using the original building roof without occupying the ground, saving land resources, and high power generation efficiency. However, due to the promotion of the market, it is found that many original buildings are old, and most of the roofs are non-walkable roofs, which can bear less load. The general photovoltaic mounting bracket is not suitable due to the large counterweight load. Utility Model Content

[0003] The utility model aims to provide a light roof photovoltaic bracket which is easy to install and has a stable structure.

[0004] A lightweight roof photovoltaic support, characterized in that it includes a frame, a panel and a photovoltaic module, the frame includes a triangular frame and a photovoltaic rail, the triangular frame is a right-angled triangle frame composed of a bottom beam, a column and an inclined beam, and the joints are fixed by connectors; a plurality of triangular frames are arranged in parallel and equidistantly, and a plurality of parallel photovoltaic rails are arranged transversely to connect all the triangular frames into a complete frame, and the joints are fixed by connectors, and panels are installed at the holes on the sides and back of the frame to block the holes; the photovoltaic module is placed on the photovoltaic rail to adjust the position and is fixed to the frame by a pressing block; structural adhesive is applied to the bottom of the bottom beam, and the frame is fixed to the installation position by bonding.

[0005] Preferably, the angle between the bottom beam and the inclined beam of the triangular frame is 5°.

[0006] The beneficial effects of the utility model are as follows: reducing the angle of the bracket can reduce the force of the wind load, and the enclosure can also prevent the wind from blowing in from the sides and back of the bracket, further reducing the force of the wind load on the frame, and at the same time can protect the internal structure of the bracket and extend the service life of the bracket. The bracket eliminates the concrete piers of the traditional bracket, realizes the lightweight of the bracket, reduces the requirements for the roof load, and is suitable for more types of roofs. The adhesive installation is carried out on the original roof without damaging the structural layer and waterproof insulation layer of the original roof. The bracket structure is stable and can effectively support the photovoltaic panels to ensure the normal operation of the photovoltaic system. The thin steel plate enclosure structure can effectively reduce the impact of wind load on the stability of the bracket and improve the wind resistance of the bracket.

[0012] Embodiment 1: A light roof photovoltaic support, firstly, according to the shape and size of the roof, the frame is designed and manufactured, the frame includes a triangular frame and a photovoltaic rail 4, the triangular frame is a right-angled triangular frame composed of a bottom beam 2, a column 1 and an inclined beam 3, and is fixed at each connection by a connector 6; a number of triangular frames are arranged in parallel and equidistantly, and six parallel photovoltaic rails 4 are arranged horizontally to connect all triangular frames into a complete frame, and the connection is fixed by a connector 6. After the roof surface is cleaned, the photovoltaic array installation position is located, the structural glue 5 is applied to the bonding surface of the bottom beam 3, and then the three frames are pressed on the roof surface to ensure that the frame and the roof are tightly fitted. After the structural glue 5 is cured, the frame can be fixed on the roof. The second step is to install the enclosure 9 in the hollows around the frame. The enclosure 9 is made of corrosion-resistant and weather-resistant materials and is customized according to the size of the support. The enclosure 9 is tightly fixed to the frame to ensure that there is no gap to prevent wind from blowing in from the back and sides of the frame. The photovoltaic assembly 8 is placed on the photovoltaic rail 4 and fixed to the frame through the pressing block 7. During the installation process, fine adjustments are made as needed to ensure that the photovoltaic array is flat as a whole.
