Longitudinal beam structure of a photovoltaic building roof assembly

Abstract

The invention discloses a longitudinal beam structure of a photovoltaic building roof assembly. The longitudinal beam structure comprises a beam body of a longitudinal beam, the beam body comprises anisosceles-trapezoid-shaped drainage groove, horizontal connecting plates are formed at the two side edges of the drainage groove in a bent mode, L-shaped bracket plates are formed on the lower end faces of the connecting plates, horizontal parts of the bracket plates are located on the lower side of the drainage groove, obliquely-arranged rib plates are formed on the horizontal parts of the bracket plates, the upper side edges of the rib plates are formed on the outer wall of the drainage groove, and a T-shaped groove rail is formed in the position, on the lower side of the drainage groove, between the bracket plates; L-shaped supports are fixed to the positions, at the lower end of the beam body, on the connecting plates, a shifting wheel is inserted between the supports, the shifting wheel is composed of an annular hub and a plurality of shifting pieces formed on the outer wall of the hub, and the shifting pieces at the lower end of the shifting wheel are inserted in the drainage groove; and the hub of the shifting wheel is fixed to a transverse transmission shaft in inserted and sleeving modes, and one end of the transmission shaft is fixedly connected with an impeller.

Description

technical field [0001] The invention relates to the technical field of photovoltaic buildings, in particular to a longitudinal beam structure of photovoltaic building roof components. Background technique [0002] A photovoltaic panel module is a power generation device that generates direct current electricity when exposed to sunlight. It consists of thin, solid photovoltaic cells almost entirely made of semiconductor materials such as silicon. At present, it is advocated that the roof of the factory building or the top floor of the carport be designed with photovoltaic panels as the roof. The photovoltaic panels can replace the tiles to protect the factory building or carport from wind and rain, and at the same time, photovoltaic panels can be used to generate electricity; but when the photovoltaic panels are used as tiles, The frame structure supporting and fixing the photovoltaic panels is required to have a good drainage function, so drainage grooves are generally desig...

Problems solved by technology

At present, it is advocated that the roof of the factory building or the top floor of the carport be designed with photovoltaic panels as the roof. The photovoltaic panels can replace the tiles to protect the factory building or carport from wind and rain, and at the same time, photovoltaic panels can be used to generate electricity; but when the photovoltaic panels are used as tiles, The frame structure supporting and fixing the photovoltaic panels is required to have a good drainage function, so drainage grooves are generally designed on the longitudinal support beams that mainly support the photovoltaic panels, and the rainwater on the photovoltaic panels can be drained through the drainage grooves on the longitudinal support beams; but now Some rainwater is usually accompanied by dust and impurities. After the dust and impurities enter the drainage tank, they are easy to collect at the outlet of the drainage tank.
