Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a multifunctional purlin structure suitable for a BIPV carport. Background Art

[0002] As a new form of renewable energy photovoltaic power generation, photovoltaic carports are also a key application scenario for the future development of photovoltaic power plants. Install early and reap the benefits sooner. They primarily consist of a carport support system, a solar panel array, a lighting and control inverter system, a charging device, and a lightning protection and grounding system. The support system primarily includes support columns, diagonal beams secured between the columns, purlins attached to the diagonal beams to support the solar panel array, and fasteners securing the panel array. A photovoltaic carport utilizes rooftop photovoltaic panels to generate electricity, which is then stored in batteries via a charging device or directly supplied to electric vehicles for charging. This electricity can be used for personal use, and even surplus power can be connected to the grid.

[0003] The existing overall structure of photovoltaic carports is generally divided into BIPV carports and ordinary photovoltaic carports. The difference is that the BIPV carport combines the component support structure and the carport structure into one to form a unified overall structure. A layer of waterproof guide rail is added between the components and the purlins to achieve a waterproof effect.

[0004] In a BIPV carport, the structural supporting purlins, the waterproof guide rails and the cable tray are three independent modules respectively. When the photovoltaic carport has a rigid requirement for waterproofing, independent waterproof guide rails are generally added to improve the overall waterproof performance. Therefore, the cost of a BIPV carport is higher than that of an ordinary photovoltaic carport. The addition of independent waterproof guide rails will increase the load-bearing capacity of the overall steel structure and the overall steel consumption. At the same time, the addition of new guide rails to the original purlin structure will also result in a longer construction period than usual. Summary of the Invention

[0005] In order to solve the above problems, the utility model provides a multifunctional purlin structure suitable for BIPV carports, which can support components while having the functions of waterproof guide rails and bridge frames, saving construction costs, high structural integration, low cost, easy installation and strong stability.

[0006] The technical solution is as follows: a multifunctional purlin structure suitable for BIPV carports, which includes photovoltaic modules, purlins and main beams, and is characterized in that longitudinal U-shaped water guide grooves are provided at the bottom of both sides of the photovoltaic modules, and the transversely arranged purlins are provided below the gap between the two longitudinally adjacent photovoltaic modules. The purlins are I-shaped and the upper and lower flanges are respectively provided with water guide curling edges. The top two sides of the purlins are respectively connected to the frames of the two adjacent photovoltaic modules by bolts, and the bottom is connected to the main beam by bolts.

[0007] It is further characterized in that the width of the lower flange of the purlin is greater than the width of the upper flange;

[0008] A Z-shaped hanging strip is provided on the water guide curling edge on the lower flange of the purlin.

[0009] After adopting the utility model, a new multifunctional purlin is designed, which is introduced into the middle multifunctional purlin through the longitudinal U-shaped guide rail for secondary drainage, and then the main drainage is carried out through the drainage groove formed by the water-guiding curling edge on the purlin, so that it has the functions of waterproof guide rail and bridge frame while supporting the components. The structure has high integration, saves construction costs, is low in cost, easy to install, and has strong stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See Figure 1 , Figure 2 , Figure 3 As shown, a multifunctional purlin structure suitable for a BIPV carport includes a photovoltaic module 1, a purlin 2 and a main beam 3. A longitudinal U-shaped water guide trough 4 is provided at the bottom of both sides of the photovoltaic module 1, and a transversely arranged purlin 2 is provided below the gap between two longitudinally adjacent photovoltaic modules 1. The purlin 2 is I-shaped and the upper and lower flanges are respectively provided with water guide curling edges 6, which can achieve the effect of water guidance. The width of the lower flange of the purlin 2 is greater than the width of the upper flange, and the water on the upper flange can be collected to the lower flange to achieve a waterproof effect.

[0014] The top sides of the purlin 2 are connected to the frames of the adjacent photovoltaic modules 1 through bolts 7, and the bottom is connected to the main beam 3 through bolts 8.

[0015] In the figure, 9 is a cover plate covering the gap, and 5 is a rubber strip filled in the gap.

[0016] During the installation of the carport, the cables between the photovoltaic systems need to be routed, and this process requires the addition of new bridges and structural connectors, which will also increase construction time and costs; therefore, a Z-shaped hanging strip 11 is provided on the water-guiding edge 6 of the lower flange of the purlin 2, which can be used to fix the cables, thereby playing the role of a bridge.

[0017] During installation, in the longitudinal direction, the U-shaped water guide trough 4 is bonded to the frame of the photovoltaic module 1 through the adhesive strip 10; in the transverse direction, the top is connected to the frame of the photovoltaic module 1 through the bolt 7, and the top of the purlin is against the two adjacent U-shaped water guide grooves 4 in the longitudinal direction, and the bottom is connected to the main beam through the bolt 8 to form a whole.

[0018] When rain falls on the photovoltaic module 1, the rain first falls into the U-shaped water channel 4 through the gap for secondary drainage, and then falls along the bolt gap and the gap between the adjacent U-shaped water channels 4 to the purlin 2 for primary drainage.
