Description

Technical Field

[0001] The utility model relates to the technical field of distributed photovoltaics, and particularly relates to a connecting guide rail for a color steel tile photovoltaic module and a photovoltaic roof, which are applicable to the construction of distributed photovoltaics on roof panels with trapezoidal convex ribs. Background Art

[0002] Solar photovoltaic power generation is a kind of clean energy. The combination of solar photovoltaic power generation and buildings can achieve the effect of energy conservation and emission reduction. A large number of color steel tile roofs are used in the domestic light steel structure factories that have been built. When installing solar photovoltaic modules on the color steel tile roofs, the existing installation methods adopt self-tapping screws for through installation and welding methods, which are not convenient for frequent maintenance, disassembly and assembly, and there are certain defects.

[0003] The existing trapezoidal color steel tile roof is fixed with a photovoltaic guide rail by using a trapezoidal clamp on the corrugated side of the trapezoidal color steel tile and installing the photovoltaic guide rail with self-drilling screws. There are the following problems. Since the self-drilling screws drill through the color steel tile from the side of the clamp and a plastic rubber ring is set for waterproofing, such a lateral penetration method will damage the color steel tile. At the same time, due to environmental factors such as the deformation of the color steel tile and wind and sun exposure, the plastic rubber ring ages, resulting in rain leakage, which is also one of the factors that plague the development of the industry. Summary of the Utility Model

[0004] In view of the problems of disassembly, maintenance, aging and rain leakage of the T-shaped color steel tile photovoltaic module, the utility model provides a connecting guide rail for a color steel tile photovoltaic module and a photovoltaic roof.

[0005] The utility model adopts the following technical solutions:

[0006] On the one hand, the utility model provides a connecting guide rail for a color steel tile photovoltaic module. The connecting guide rail is a hollow tubular structure. An inward concave trapezoidal groove is formed at the lower end surface thereof. A plurality of through holes I are arranged at intervals at the bottom of the trapezoidal groove. The cross-section of the trapezoidal groove is consistent with the cross-section of the trapezoidal convex rib of the color steel tile, and both side surfaces of the trapezoidal groove are completely attached to both side surfaces of the trapezoidal convex rib of the color steel tile. A notch running through the entire length is provided at the upper end surface of the connecting guide rail. An aluminum alloy connecting block is installed at the notch. Both ends of the aluminum alloy connecting block are respectively attached to the lower end surfaces of both sides of the notch. A through hole II for passing through a fastener is also provided at the middle position of the aluminum alloy connecting block.

[0007] Further, both sides of the notch form anti-disengagement hooks extending inward. Both ends of the aluminum alloy connecting block form flanges extending toward the same side. The two flanges are located outside the two anti-disengagement hooks, and the two form a snap connection.

[0008] Further preferably, both sides of the upper end surface of the connecting guide rail extend outward beyond its two side surfaces to form additional support plates.

[0009] On the other hand, the utility model provides a color steel tile photovoltaic roof, which includes purlins, color steel tiles, connecting rails and photovoltaic modules. The color steel tiles are arranged on the purlins. The connecting rails are the above-mentioned connecting rails, and the connecting rails are installed at intervals on the trapezoidal ribs of the color steel tiles, and the two are fixedly connected through fastening connectors; the photovoltaic modules are installed at the upper end surface of the connecting rails, and aluminum alloy pressing blocks are arranged on the photovoltaic modules, and the aluminum alloy pressing blocks, photovoltaic modules and aluminum alloy connecting blocks are fixedly connected through fastening connectors.

[0010] Preferably, the connecting rail and the color steel tile are connected by self-drilling screws with waterproof caps, and the lower end of the self-drilling screw is connected to the purlin.

[0011] The technical solution of the utility model has the following advantages:

[0012] A. The connecting rail with trapezoidal grooves and notches provided by the utility model has the trapezoidal grooves completely fitting with the ribs, making the connecting rail more firmly installed on the trapezoidal ribs of the color steel tile. At the same time, self-drilling screws with waterproof caps are arranged in the hollow cavity of the trapezoidal ribs to avoid problems such as rain leakage; the setting of the notches and aluminum alloy connecting blocks is more convenient for disassembling, installing and maintaining the photovoltaic roof, improving the installation and maintenance efficiency and greatly reducing the labor cost.

[0013] B. The connecting rail with trapezoidal grooves and notches provided by the utility model is connected to the secondary structure purlin of the roof, directly transmitting force to the stressed member, with more definite force transmission and more reliable connection. Compared with the traditional adhesive aluminum alloy fixture scheme, the connection strength of the self-drilling screw is higher than that of the adhesive.

[0014] C. The connection method and types of accessories provided by the utility model, compared with the traditional adhesive aluminum alloy fixture scheme, reduce the aluminum alloy fixtures and have lower costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the present utility model provides a connecting guide rail for a color steel tile photovoltaic module.

At the same time, a notch 13 running through the entire length is provided at the upper end surface of the connecting guide rail 1. An aluminum alloy connecting block 3 is installed at the notch 13. The two ends of the aluminum alloy connecting block 3 are respectively attached to the lower end surfaces of the two side edges of the notch 13.

The color steel tiles 2 are arranged on the purlins 4, and the connecting guide rails 1 are installed at intervals on the trapezoidal ribs 21 of the color steel tiles 2, and the two are fixedly connected through fastening connectors. As Figure 6 shown, the connecting guide rail 1 and the color steel tile 2 are connected by self-drilling screws 6 with waterproof caps, and the lower end of the self-drilling screws 6 is connected to the purlins 4. The photovoltaic module 5 is installed at the upper end surface of the connecting guide rail 1. Aluminum alloy pressing blocks 7 are provided on the photovoltaic module 5, and the aluminum alloy pressing blocks 7, the photovoltaic module 5 and the aluminum alloy connecting blocks 3 are fixedly connected by bolts 8, so as to fix the photovoltaic module 5 on the connecting guide rail 1, making it more convenient to disassemble, install and repair the photovoltaic module 5. At the same time, the self-drilling screws 6 with waterproof caps are adopted, and the waterproof caps and the self-drilling screws 6 are arranged inside the hollow cavity of the connecting guide rail 1, avoiding problems such as rain leakage.
