Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, and in particular to a photovoltaic buckle assembly with barbs and a floating photovoltaic system. Background Technology

[0002] Photovoltaic support structures are an important component of photovoltaic arrays in solar photovoltaic power generation systems and are an essential part of installing photovoltaic modules. Photovoltaic support structures are mainly divided into two types: fixed and tracking. Among them, fixed support structures are the most widely used in current engineering applications.

[0003] With the increasing demand for carbon neutrality, the demand for photovoltaic power generation construction is also growing, with construction capacity constantly increasing and the demand for land increasing. During the construction and installation process, the installation efficiency of photovoltaic modules will affect the construction progress and construction costs. The main problems with the current photovoltaic mounting system for fixing photovoltaic modules are that, on the one hand, the installation structure and installation procedures are relatively complex, affecting the installation efficiency; on the other hand, the installation process requires a large number of parts, resulting in high installation costs.

[0004] Currently, to ensure the safety of floating photovoltaic systems when struck by lightning, the clips on the frame of the photovoltaic modules need to have a piercing function so that electrical conductivity can be achieved between the photovoltaic frame and the clips, allowing the photovoltaic modules to be grounded. The drawback is that the clip assembly has a complex structure, which affects the installation efficiency of the photovoltaic modules.

[0005] In view of this, it is necessary to develop a photovoltaic snap-fit ​​component with barbs and a floating photovoltaic system. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to disclose a photovoltaic snap-on component with barbs and a floating photovoltaic system.

[0007] The first objective of this invention is to provide a photovoltaic snap-fit ​​assembly with barbs.

[0008] The second objective of this invention is to provide a floating photovoltaic system.

[0009] To achieve the first objective mentioned above, this utility model provides a photovoltaic buckle assembly with barbs, including a support beam and a wave-shaped card disposed on the upper surface of the support beam, wherein downward-curving barbs are respectively provided on both sides of the wave-shaped card;

[0010] The lower frame of the photovoltaic module is inserted between the upper surface of the support beam and the wavy card, with the tips of the barbs piercing the lower frame.

[0011] Preferably, the support beam has a notch, which faces the wavy card.

[0012] Preferably, the tip of the barb extends into the notch by 0.1mm-0.5mm.

[0013] Preferably, the wavy card includes a convex upper surface and a concave lower surface;

[0014] The barbs are provided on the concave surface.

[0015] Preferably, the wavy card and the support beam are a single unit.

[0016] Preferably, a snap-fit ​​assembly is provided at the end of the support beam.

[0017] Preferably, the buckle assembly includes a fastening plate and an L-shaped buckle, the fastening plate being fixed to the upper surface of the support beam, and the L-shaped buckle engaging the upper frame of the photovoltaic module.

[0018] Preferably, a first wavy card and a second wavy card are provided on the upper surface of the support beam;

[0019] The end of the support beam is provided with a first fastening assembly and a second fastening assembly;

[0020] The first wavy card and the first snap-fit ​​component work together to engage the first photovoltaic module, and the second wavy card and the second snap-fit ​​component work together to engage the second photovoltaic module.

[0021] Preferably, the angle between the support beam and the horizontal plane is 5°-10°.

[0022] Based on the same inventive principle, in order to achieve the second inventive objective mentioned above, this utility model provides a floating photovoltaic system, in which several floating components form a floating platform, and a photovoltaic buckle component with barbs as described in the first invention is installed on the floating platform.

[0023] Compared with the prior art, the technical effects of this utility model are as follows:

[0024] A wavy card is formed on the upper surface of the self-supporting beam by punching, with a corresponding hollowed-out notch below the wavy card. Barbs are formed on the concave side of the wavy card by punching. When the lower frame of the photovoltaic module is not engaged, the lowest point of the concave side of the wavy card is flush with the upper surface of the supporting beam, and the barbs extend slightly into the notch. During the process of inserting the lower frame of the photovoltaic module between the wavy card and the upper surface of the supporting beam, the wavy card is slightly lifted, and the barbs cut through the oxide layer on the surface of the lower frame, allowing the barbs to penetrate the lower frame. Then, the grounding system is connected through the supporting beam, so that the photovoltaic module is engaged and grounded. At the same time, the wavy card and the barbs form a combination that binds the lower frame, so that the photovoltaic module is stably engaged and not easily detached. Attached Figure Description

[0040] Embodiment 1

[0041] With reference to Figures 1-11 as shown, this embodiment discloses a specific implementation of a photovoltaic buckle assembly with barbs.

[0042] A photovoltaic buckle assembly with barbs, with reference to Figures 1-11 as shown, comprises a support beam 1 and a wavy card 2 disposed on the upper surface 11 of the support beam 1. Two sides of the wavy card 2 are respectively provided with downward-bent barbs 3. The support beam 1 is provided with a notch 12, and the notch 12 is directly opposite to the wavy card 2. The lower frame 41 of the photovoltaic module 4 is inserted between the upper surface 11 of the support beam 1 and the wavy card 2, and the tip of the barb 3 pierces into the lower frame 41.

[0043] Specifically, the wavy card 2 and the support beam 1 are an integral unit. The support beam 1 is preferably made of aluminum alloy. The wavy card 2 is formed by punching from the upper surface 11 of the support beam 1. A corresponding hollowed-out notch 12 is formed below the wavy card 2. The wavy card 2 includes an upper convex surface 21 and a lower concave surface 22. The upper convex surface 21 is connected to the upper surface 11, and the lower concave surface 22 and the upper convex surface 21 are smoothly transitioned. The end of the upper convex surface 21 curves upward and forms the entrance of the lower frame 41 with the upper surface 11. A barb 3 is formed by punching at the lower concave surface 22 of the wavy card 2. The barb 3 is set on the lower concave surface 22, and preferably at the lowest point of the lower concave surface 22. When the lower frame 41 of the photovoltaic module 4 is not engaged, the wavy card 2... The lowest point of the concave surface 22 of the corrugated card 2 is flush with the upper surface 11 of the support beam 1, while the barb 3 extends slightly into the notch 12. For example, the tip of the barb 3 extends into the notch 12 to a height of 0.1mm-0.5mm, preferably 0.2mm. During the process of inserting the lower frame 41 of the photovoltaic module 4 between the corrugated card 2 and the upper surface 11 of the support beam 1, the corrugated card 2 is slightly supported, and the tip of the barb 3 cuts through the oxide layer on the surface of the lower frame 41, so that the barb 3 pierces into the lower frame 41. Then, the grounding system is connected through the support beam 1, so that the photovoltaic module 4 is locked and grounded. At the same time, the corrugated card 2 and the barb 3 form a combination that binds the lower frame 41, so that the photovoltaic module 4 is stably locked and not easy to detach.

[0044] See Figures 8 to 11The angle between the support beam 1 and the horizontal plane is 5°-10°. The end of the support beam 1 is provided with a buckle assembly 13. The buckle assembly 13 includes a fastening plate 131 and an L-shaped buckle 132. The fastening plate 131 is fixed to the upper surface 11 of the support beam 1. The L-shaped buckle 132 engages the upper frame of the photovoltaic module 4. When assembling the photovoltaic module 4, the lower frame 41 on one side of the photovoltaic module 4 is first inserted between the wavy card 2 and the upper surface 11 of the support beam 1. Then, the upper frame 42 on the other side of the photovoltaic module 4 is engaged with the L-shaped buckle 132. That is, the frames on both sides of the photovoltaic module 4 are engaged with the wavy card 2 and the L-shaped buckle 132 respectively. To ensure the photovoltaic module 4 is securely engaged, the upper surface 11 of the support beam 1 is provided with a first wavy clip 23 and a second wavy clip 24. The first wavy clip 23 and the second wavy clip 24 have the same structure as the wavy clip 2, but their openings are opposite to each other. The end of the support beam 1 is provided with a first latching component 133 and a second latching component 134. The first latching component 133 and the second latching component 134 are the same as the latching component 13, but their orientations are opposite. The first wavy clip 23 and the first latching component 133 engage the first photovoltaic module 43, and the second wavy clip 24 and the second latching component 134 engage the second photovoltaic module 44. The first photovoltaic module 43 and the second photovoltaic module 44 are adjacent and in contact with each other. Two support beams 1 are provided below the adjacent first photovoltaic module 43 and the second photovoltaic module 44.

[0045] Example 2

[0046] This embodiment discloses a specific implementation of a floating photovoltaic system.

[0047] A floating photovoltaic system, see Figures 8 to 11 A floating platform 6 is composed of several floating components 5, and a barbed photovoltaic clip assembly as described in Embodiment 1 is installed on the floating platform 6. (See also...) Figure 8 Several floating components 5 form a rectangular floating platform 6. The center of the floating platform 6 is hollowed out. A first inclined bracket 7 and a second inclined bracket 8 are respectively set on both sides of the floating platform 6. One end of the support beam 1 is fastened to the end of the first inclined bracket 7, and the other end of the support beam 1 is fastened to the end of the second inclined bracket 8. When assembling the floating photovoltaic system, the floating platform 6 is assembled first, and then the first inclined bracket 7, the second inclined bracket 8, and the support beam 1 are fixedly installed. Then, the lower edge of one side of the photovoltaic module 4 is directly inserted between the wavy clip 2 and the upper surface 11 of the support beam 1. Finally, the L-shaped buckle 132 is engaged, which can quickly complete the installation of the photovoltaic module 4 and greatly improve the installation efficiency.
