Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic shed drainage, in particular to a high and low purlin drainage structure of a flat slope photovoltaic shed. Background Art

[0002] With the popularization of zinc-aluminum-magnesium high-strength anti-corrosion coatings, more and more photovoltaic engineering applications have chosen zinc-aluminum-magnesium coated steel; this material has 30 years of anti-corrosion ability and the unique quality of self-healing and resistance to scratch damage, making it the preferred anti-corrosion steel in humid environments.

[0003] As fully assembled zinc-aluminum-magnesium photovoltaic sheds are becoming more and more popular among customers in China, the market demand is relatively large; the current drainage scheme for photovoltaic sheds is mainly based on a 1:10 slope. The slope is created through the structural surface formed by beams and purlins, and then the photovoltaic panels are installed. When in use, rainwater will flow down the slope of the photovoltaic panels, thereby avoiding rainwater accumulation.

[0004] For example, the prior art (announcement number: CN216552622U, announcement date: 2022.05.17) discloses a photovoltaic installation structure suitable for a steel structure roof, including a roof with at least one slope structure; it uses photovoltaic modules to replace tiles in traditional steel structure roofs, making photovoltaic modules an important component of the roof structure, giving full play to the structural function and photovoltaic function of the photovoltaic modules.

[0005] However, in some urban areas with strict height restrictions, customers often require that the photovoltaic shed be designed as a flat slope to maximize the use of the height space under the panels. The design of the flat slope photovoltaic shed has the advantages of flexible layout and better structural wind resistance than the photovoltaic shed with a structural slope of 1:10. However, the flat slope photovoltaic shed also has obvious disadvantages: 1. Water easily accumulates on the roof of the photovoltaic shed, affecting the power generation efficiency; 2. Long-term water accumulation will also cause dust accumulation, further affecting the operation quality of the power station.

[0006] Therefore, it is necessary to design a high and low purlin drainage structure for photovoltaic sheds on flat slopes to solve the above problems. Utility Model Content

[0010] Furthermore: Purlins are fixedly installed on the upper sides of the high purlin supports and the low purlin supports, photovoltaic clamps are fixedly installed on the upper edges of the purlins, and the edges on the left and right sides of the photovoltaic panels are fixedly installed on the purlins through the photovoltaic clamps.

[0015] Furthermore: the inclination gradient of the photovoltaic panel is greater than 3%.

[0016] Further: the photovoltaic clamp includes a base and two clamping sheet metals. The base is fixedly installed at the two edges of the upper side of the purlin. The two clamping sheet metals are respectively fixedly installed at the two edges of the base. A snap-fit ​​position is formed at the bottom edge of the photovoltaic panel.
