Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic carport technology, and specifically relates to a photovoltaic carport system. Background Technology

[0002] Most flexible photovoltaic (PV) modules are frameless and are installed using a mounting and pressure strip fixing method. A transparent polycarbonate sheet is typically used as the bottom support for the flexible PV module. The flexible PV module is adhered to the bottom surface of the transparent polycarbonate sheet, and its edges are adhered to the supporting steel pipe and fixed to the supporting steel pipe with metal pressure strips and self-tapping screws.

[0003] However, this installation method has the following drawbacks:

[0004] 1. The connection between adjacent flexible photovoltaic modules is not stable enough, and the flexible modules are prone to separation, affecting their use;

[0005] 2. The inner surface of the polycarbonate sheet is prone to mold growth, and dirt easily accumulates between the polycarbonate sheet and the flexible photovoltaic module;

[0006] 3. Polycarbonate sheets increase costs, and the need to drill cable routing holes for polycarbonate sheets increases installation workload;

[0007] Therefore, a photovoltaic carport system is needed to solve the problems of unstable connection between adjacent flexible photovoltaic modules in the existing technology, easy separation of flexible modules affecting use; easy mold growth on the inner surface of the polycarbonate sheet, easy accumulation of dirt between the polycarbonate sheet and the flexible photovoltaic module; increased cost due to the polycarbonate sheet, and the need to drill cable holes in the polycarbonate sheet, which increases the workload of installation. Utility Model Content

[0008] The purpose of this invention is to provide a photovoltaic carport system to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic carport system, comprising several flexible photovoltaic module bodies, wherein several evenly distributed support rods are bonded to the bottom surface of the flexible photovoltaic module body along its length direction by structural sealant; several evenly distributed snap-fit ​​holes are respectively opened on both sides of one side of the flexible photovoltaic module body, and stainless steel fasteners are detachably snapped between two opposite snap-fit ​​holes; a pressure strip is provided between the adjacent sides of the top surfaces of two adjacent flexible photovoltaic module bodies, and several evenly distributed mounting holes are respectively opened on both sides of the top surface of the pressure strip, and several evenly distributed pressure blocks are provided on the top surface of the pressure strip.

[0010] It should be noted in the solution that fastening screws are movably connected to both sides of the top surface of the pressure block, and the threads of the fastening screws pass through the mounting hole and the flexible photovoltaic module body.

[0011] It is worth noting that a first double-sided self-adhesive butyl tape is bonded between two adjacent flexible photovoltaic module bodies.

[0012] Furthermore, it should be noted that a second double-sided self-adhesive butyl tape is respectively adhered to the side of the top surface of two adjacent flexible photovoltaic module bodies, and the top surface of the second double-sided self-adhesive butyl tape is adhered to the bottom surface of the pressure strip.

[0013] In a preferred embodiment, the bottom surface of the support rod is provided with symmetrically distributed support steel pipes, and the top surface of the support steel pipes is threaded with a number of evenly distributed self-tapping screws, the tail ends of which are threaded to the bottom surface of the support steel pipes.

[0014] In a preferred embodiment, the top surface of the pressure strip has a plurality of evenly distributed elongated holes, and weather-resistant sealant is disposed in the elongated holes.

[0015] In a preferred embodiment, the pressure strip has three water guides bonded to the two corners and the middle of the flexible photovoltaic module body in a direction perpendicular to the water flow.

[0016] Compared with the prior art, the photovoltaic carport system provided by this utility model includes at least the following:

[0017] Beneficial effects:

[0018] (1) The first double-sided self-adhesive butyl tape allows for the initial connection between adjacent flexible photovoltaic modules. The snap-fit ​​holes and stainless steel fasteners allow for further connection between adjacent flexible photovoltaic modules. The pressure blocks, pressure strips and fastening screws ensure a more stable connection between adjacent flexible modules. This avoids the problem of mold growth on the inner surface of the polycarbonate sheet during installation, which would cause dirt to accumulate between the polycarbonate sheet and the flexible photovoltaic module. It also avoids the increased cost of the polycarbonate sheet and the need to open cable routing holes in the polycarbonate sheet, which would increase the workload of installation.

[0019] (2) The supporting steel pipes can support the flexible photovoltaic module body, which avoids the flexible photovoltaic module body from forming a concave surface due to deformation when there is no polycarbonate sheet support. This would cause dirt to accumulate on the concave surface, reduce the output power, and increase the risk of hot spots and hidden cracks in the battery cells. Attached Figure Description

[0031] Please see Figure 1-6 This utility model provides a photovoltaic carport system, including a plurality of flexible photovoltaic module bodies 100. A plurality of evenly distributed support rods are bonded to the bottom surface of the flexible photovoltaic module body 100 along the length direction by structural sealant. A plurality of evenly distributed snap-fit ​​holes 101 are respectively opened on both sides of one side of the flexible photovoltaic module body 100. Stainless steel fasteners 102 are detachably snapped between two opposite snap-fit ​​holes 101. A pressure strip 200 is provided between the adjacent sides of the top surfaces of two adjacent flexible photovoltaic module bodies 100. A plurality of evenly distributed mounting holes 202 are respectively opened on both sides of the top surface of the pressure strip 200. A plurality of evenly distributed pressure blocks 300 are provided on the top surface of the pressure strip 200.

[0032] Furthermore, fastening screws 301 are movably connected to both sides of the top surface of the pressure block 300, and the threads of the fastening screws 301 pass through the mounting hole 202 and the flexible photovoltaic module body 100.

[0033] By using the fastening screws 301, the pressure block 300 can tightly contact the pressure strip 200 with the flexible photovoltaic module body 100, and at the same time make the connection between two adjacent flexible photovoltaic module bodies 100 more stable.

[0034] Furthermore, a first double-sided self-adhesive butyl tape is bonded between two adjacent flexible photovoltaic module bodies 100.

[0035] The first double-sided self-adhesive butyl tape allows for a preliminary connection between two adjacent flexible photovoltaic module bodies 100.

[0036] Furthermore, a second double-sided self-adhesive butyl tape is respectively bonded to one side of the top surface of two adjacent flexible photovoltaic module bodies 100, and the top surface of the second double-sided self-adhesive butyl tape is bonded to the bottom surface of the pressure strip 200.

[0037] The second double-sided self-adhesive butyl tape allows the pressure strip 200 to be initially connected to two adjacent flexible photovoltaic module bodies 100.

[0038] This solution includes the following steps: When assembling and installing the flexible photovoltaic module body 100, firstly, multiple support rods are bonded to the bottom surface of the flexible photovoltaic module body 100 using structural sealant. Then, support steel pipes 400 are installed on their bottom surfaces using self-tapping screws, thus supporting the flexible photovoltaic module body 100. The positions of two adjacent flexible photovoltaic module bodies 100 are adjusted, and the first double-sided self-adhesive butyl tape is applied to the adjacent sides of the two adjacent flexible photovoltaic module bodies 100, establishing a preliminary connection between them. Finally, multiple stainless steel fasteners 102 are installed. Between the two corresponding snap-fit ​​holes 101, the two adjacent flexible photovoltaic module bodies 100 are further connected. The second double-sided self-adhesive butyl tape is adhered to the side of the top surface of the adjacent flexible photovoltaic module body 100, and the pressure strip 200 is adhered to the second double-sided self-adhesive butyl tape, so that the pressure strip 200 is initially connected to the adjacent flexible photovoltaic module body 100. Then, weather-resistant sealant is injected into the elongated hole 201, and multiple pressure blocks 300 are snapped onto the pressure strip 200. Finally, the fastening screws 301 are connected to the mounting hole 202 and the flexible photovoltaic module body 100, so that the flexible photovoltaic module body 100 is stably fixed.

[0039] As can be seen from the above working process: the first double-sided self-adhesive butyl tape enables the adjacent flexible photovoltaic module bodies 100 to be initially connected; the snap-fit ​​holes 101 and stainless steel fasteners 102 enable the adjacent flexible photovoltaic module bodies 100 to be further connected; and the pressure blocks 300, pressure strips 200, and fastening screws 301 make the connection between the adjacent flexible photovoltaic module bodies 100 more stable. At the same time, it avoids the problem of mold growth on the inner surface of the polycarbonate sheet when using it for support installation, which makes it easy for dirt to accumulate between the polycarbonate sheet and the flexible photovoltaic module body 100. It also avoids the problem of polycarbonate sheets increasing costs and requiring cable routing holes, which increases the workload of installation.

[0040] The supporting steel pipe 400 can support the flexible photovoltaic module body 100, avoiding the formation of a concave surface due to deformation when the bottom of the flexible photovoltaic module body 100 is not supported by a polycarbonate sheet. This would cause dirt to accumulate on the concave surface, reduce the output power, and increase the risk of hot spots and microcracks in the cells.

[0041] Furthermore, the bottom surface of the support rod is provided with symmetrically distributed support steel pipes 400, and the top surface of the support steel pipes 400 is threaded with a number of evenly distributed self-tapping screws, the tail end of the self-tapping screws being threaded to the bottom surface of the support steel pipes 400.

[0042] The flexible photovoltaic module body 100 can be supported by the supporting steel pipe 400.

[0043] Furthermore, the top surface of the pressure strip 200 has several evenly distributed elongated holes 201, and weather-resistant sealant is provided in the elongated holes 201.

[0044] The use of elongated holes 201 and weather-resistant sealant further enhances the stability of the connection between the pressure strip 200 and the flexible photovoltaic module body 100.

[0045] Furthermore, the pressure strip 200 has three water guides bonded to the two corners and the middle of the flexible photovoltaic module body 100 in the direction perpendicular to the water flow.

[0046] The water-guiding clips allow water to be drained from the top surface of the flexible photovoltaic module body 100.

[0047] In summary: When splicing and installing the flexible photovoltaic module body 100, firstly, multiple support rods are bonded to the bottom surface of the flexible photovoltaic module body 100 using structural sealant. Then, support steel pipes 400 are installed on their bottom surfaces using self-tapping screws, thus supporting the flexible photovoltaic module body 100. The positions of adjacent flexible photovoltaic module bodies 100 are adjusted, and the first double-sided self-adhesive butyl tape is applied to the adjacent sides of the two flexible photovoltaic module bodies 100, establishing a preliminary connection between them. Finally, multiple stainless steel fasteners 102 are installed on the opposite sides. Between the snap-fit ​​holes 101, the two adjacent flexible photovoltaic module bodies 100 are further connected. The second double-sided self-adhesive butyl tape is adhered to the side of the top surface of the adjacent flexible photovoltaic module body 100, and the pressure strip 200 is adhered to the second double-sided self-adhesive butyl tape, so that the pressure strip 200 and the adjacent flexible photovoltaic module body 100 are initially connected. Then, weather-resistant sealant is injected into the elongated hole 201, and multiple pressure blocks 300 are snapped onto the pressure strip 200. Finally, the fastening screws 301 are connected to the mounting hole 202 and the flexible photovoltaic module body 100, so that the flexible photovoltaic module body 100 is stably fixed.

[0048] The flexible photovoltaic module body 100, the first double-sided self-adhesive butyl tape, and the second double-sided self-adhesive butyl tape can all be purchased from the market. These are mature technologies in the field and have been fully disclosed, so they will not be repeated in the specification.
