[Technical field]
[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to an installation structure of a photovoltaic component. [Background technology]
[0002] As the size of photovoltaic modules increases, the cost reduction space of existing aluminum alloy frames is relatively small due to the limitations of materials, structure and process. At present, the market has seen the emergence of rigid structure frames and composite material frames as cost reduction solutions. Since these frame materials have changed significantly compared to aluminum alloy frames, they have had a certain impact on the traditional photovoltaic module installation method.
[0003] The pressure plate installation structure used in the prior art fixes the photovoltaic module by pressing and fixing the C side of the module frame. Since the pressure plate is fixed by the pressure plate bolts, it mainly applies downward pressure to the C side of the module frame, and has no limit in the horizontal direction. In strong winds or other horizontal external forces, horizontal misalignment between the pressure plate and the C side of the module frame is easy to occur. [Contents of the utility model]
[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a pressure plate installation structure for a photovoltaic module, so as to solve the problem of horizontal misalignment between the pressure plate and the C side of the component frame in the prior art.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a pressure plate mounting structure of a photovoltaic module, comprising a mounting beam and a pressure plate assembly for fixing the photovoltaic module to the mounting beam, the pressure plate assembly comprising an upper pressure plate arranged above the mounting beam, a lower pressure plate arranged below the mounting beam, and pressure plate bolts connecting the upper pressure plate and the lower pressure plate, the photovoltaic module is provided with a module frame and the module frame has a C-edge, the edge of the C-edge is provided with an upper convex edge, the bottom surface of the upper pressure plate is provided with a first lower protrusion pressed on the C-edge, the first lower protrusion and the upper convex edge are limitedly matched to prevent the first lower protrusion from being misaligned and separated from the C-edge.
[0006] Preferably, the first lower protrusions are distributed in two rows along the width direction of the C side, and the first lower protrusions in a row close to the edge of the C side are limitedly matched with the upper convex edge.
[0007] Preferably, the first lower protrusion and the upper pressing plate are formed integrally.
[0008] Preferably, the first lower protrusion is integrally stamped with the upper pressing plate, and a groove is formed on the upper surface of the upper pressing plate corresponding to the position of the first lower protrusion.
[0009] Preferably, the height H2 of the first lower protrusion is ≥ the height H1 of the upper convex edge.
[0010] Preferably, the upper pressure plate is provided with a fixing hole connected to the pressure plate bolts, the bottom surface of the upper pressure plate is provided with a second lower protrusion pressed with the upper surface of the mounting beam, and the first lower protrusion and the second lower protrusion are located on opposite sides of the fixing hole.
[0011] Preferably, the upper pressing plate is provided with an upper bending edge on a side close to the second lower protrusion.
[0012] Preferably, the inner side edge of the upper pressure plate is limitedly matched with the edge of the component frame B; and / or the fixing hole is a waist-shaped hole.
[0013] Preferably, the upper pressing plate and the lower pressing plate are made of aluminum alloy or stainless steel; and / or the component frame is made of aluminum alloy or stainless steel.
[0014] Preferably, the mounting beam is a C-shaped steel or a U-shaped steel.
[0015] The utility model adopts the above technical solution and has the following beneficial effects:
[0016] 1. The utility model is provided with an upper convex edge on the edge of the C side of the component frame, and at the same time, the bottom surface of the upper pressure plate is provided with a first lower protrusion pressed on the C side. On the one hand, the first lower protrusion can ensure that the upper pressure plate can press the C side of the component frame, and on the other hand, the first lower protrusion cooperates with the upper convex edge to prevent the first lower protrusion from being misaligned and separated from the C side, thereby making the pressing of the C side of the component frame more reliable, solving the problem of horizontal misalignment between the pressure plate and the C side of the component frame in the prior art.
[0017] 2. The first lower protrusions are distributed in two rows along the width direction of the C side, so as to ensure that the upper pressure plate can press multiple positions on the C side of the component frame to ensure reliable pressing, and a row of first lower protrusions close to the edge of the C side cooperate with the upper convex edge limiter to prevent the first lower protrusions from being misaligned and separated from the C side.
[0018] 3. Since the first lower protrusion is integrally stamped with the upper pressing plate, and a groove is formed on the upper surface of the upper pressing plate corresponding to the position of the first lower protrusion, the manufacturing cost of the upper pressing plate can be reduced, and the integral stamping ensures the molding quality and structural strength.
[0019] 4. Since the height H2 of the first lower protrusion is ≥ the height H1 of the upper convex edge, it is ensured that the upper pressing plate can press the edge C of the component frame.
[0020] 5. The bottom surface of the upper pressure plate is provided with a second lower protrusion pressed against the upper surface of the mounting beam, and the first lower protrusion and the second lower protrusion are located on opposite sides of the fixing hole. In this way, after the upper pressure plate is tightened by the pressure plate bolts, on opposite sides of the bolts, the first lower protrusion can press the C side of the component frame, and the second lower protrusion can be pressed against the upper surface of the mounting beam, so that the forces on opposite sides of the pressure plate bolts are balanced and reasonable, ensuring that the C side of the component frame is reliably pressed.
[0021] 6. An upper bending edge is provided on the side of the upper pressure plate close to the second lower protrusion to prevent the side of the upper pressure plate close to the second lower protrusion from bending downward to affect the full contact between the second lower protrusion and the upper surface of the mounting beam, thereby ensuring that the second lower protrusion can be pressed against the upper surface of the mounting beam, thereby ensuring that the relative forces on the two sides of the pressure plate bolts are balanced and reasonable.
[0022] 7. While the first lower protrusion is limited with the upper convex edge, the inner side of the upper pressing plate is limited with the B side of the component frame. Since the upper pressing plate is limited in both the inner and outer directions, it can prevent the upper pressing plate from being misaligned and separated from the C side. Since the fixing hole is a waist-shaped hole, it is convenient to connect the fixing hole with the pressing plate bolt.
[0023] 8. The upper and lower pressure plates are made of aluminum alloy or stainless steel to avoid rust, extend service life and reduce maintenance costs.
[0024] 9. Compared with aluminum alloy materials, the cost can be further reduced if the mounting beam is C-shaped steel or U-shaped steel.
[0025] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0035] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0036] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0037] Reference Figures 1 to 4 As shown, a pressure plate mounting structure of a photovoltaic module includes a mounting beam 200 and a pressure plate assembly for fixing the photovoltaic module to the mounting beam. The pressure plate assembly includes an upper pressure plate 2 arranged above the mounting beam, a lower pressure plate 3 arranged below the mounting beam, and a pressure plate bolt 4 connecting the upper pressure plate 2 and the lower pressure plate 3. The photovoltaic module is provided with a module frame 1 and the module frame 1 has a C edge 11, the edge of the C edge is provided with an upper convex edge 12, the bottom surface of the upper pressure plate is provided with a first lower protrusion 21 pressed on the C edge, and the first lower protrusion 21 is limitedly matched with the upper convex edge 12 to prevent the first lower protrusion from separating from the C edge.
[0038] In the above technical solution, an upper convex edge is provided on the edge of the C side of the component frame, and at the same time, a first lower protrusion pressed on the C side is provided on the bottom surface of the upper pressure plate. On the one hand, the first lower protrusion can ensure that the upper pressure plate can press the C side of the component frame, and on the other hand, the first lower protrusion cooperates with the upper convex edge to prevent the first lower protrusion from being misaligned and separated from the C side, thereby making the pressing of the C side of the component frame more reliable, solving the problem of horizontal misalignment between the pressure plate and the C side of the component frame in the prior art.
[0039] Preferably, the first lower protrusions 21 are distributed in two rows along the width direction of the C side, and the first lower protrusions in one row near the edge of the C side are limitedly matched with the upper convex edge 12. The arrangement of the two rows of first protrusions can ensure that the upper pressing plate presses multiple positions on the C side of the frame of the component to ensure reliable pressing, and the first lower protrusions in one row near the edge of the C side are limitedly matched with the upper convex edge to prevent the first lower protrusions from being misaligned and separated from the C side.
[0040] The first lower protrusion 21 is integrally formed with the upper pressing plate 2. As an embodiment, the first lower protrusion is integrally stamped with the upper pressing plate, and a groove is formed on the upper surface of the upper pressing plate corresponding to the position of the first lower protrusion. In this way, the manufacturing cost of the upper pressing plate can be reduced, and the integral stamping ensures the molding quality and structural strength.
[0041] Preferably, the height H2 of the first lower protrusion is greater than or equal to the height H1 of the upper convex edge, so as to ensure that the upper pressing plate can press the edge C of the component frame.
[0042] Furthermore, the upper pressing plate 2 is provided with a fixing hole 22 connected with the pressing plate bolts, and the bottom surface of the upper pressing plate is provided with a second lower protrusion 23 pressed with the upper surface of the mounting beam, and the first lower protrusion 21 and the second lower protrusion 23 are located on opposite sides of the fixing hole 22. It can be understood that the first lower protrusion, the second lower protrusion and the upper pressing plate are integrally stamped and formed, and grooves are formed on the upper surface of the upper pressing plate corresponding to the positions of the first lower protrusion and the second lower protrusion. After the upper pressing plate is tightened by the pressing plate bolts, the first lower protrusion can press the C side of the component frame on the opposite sides of the bolts, and the second lower protrusion can be pressed on the upper surface of the mounting beam, so that the forces on the opposite sides of the pressing plate bolts are balanced and reasonable, ensuring that the C side of the component frame is reliably pressed.
[0043] Furthermore, the upper pressing plate 2 is provided with an upper bending edge 24 on one side close to the second lower protrusion to avoid the side of the upper pressing plate close to the second lower protrusion bending downward to affect the full contact between the second lower protrusion and the upper surface of the mounting beam, so as to ensure that the second lower protrusion can be pressed against the upper surface of the mounting beam, thereby ensuring that the relative forces on the two sides of the pressing plate bolts are balanced and reasonable.
[0044] While the first lower protrusion is limited with the upper convex edge, the inner side edge 25 of the upper pressing plate is limited with the component frame B edge 13. Since the upper pressing plate is limited in both inner and outer directions, the upper pressing plate and the C edge can be prevented from being misaligned and separated.
[0045] Preferably, the fixing hole 22 is a waist-shaped hole. Since the relative positions of the upper pressing plate and the component frame are fixed, the fixing hole is designed as a waist-shaped hole to facilitate the bolt connection between the fixing hole and the pressing plate.
[0046] Furthermore, the upper pressing plate 2 and the lower pressing plate 3 are made of aluminum alloy or stainless steel. The component frame 1 is made of aluminum alloy or stainless steel. This prevents corrosion, prolongs service life, and reduces maintenance costs. The mounting beam 200 is made of C-shaped steel or U-shaped steel, which is less expensive than aluminum alloy materials.
[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
