Technical field

[0001] The utility model belongs to the technical field of photovoltaic power generation equipment, and specifically relates to photovoltaic component installation technology. [Background Technology]

[0002] Plastic wing nuts are common components in photovoltaic mounting structures, usually installed on C-shaped beams in conjunction with nut blocks. For example, Chinese utility model patent No. CN 208539845U discloses a photovoltaic module structure, including a first photovoltaic assembly consisting of multiple first photovoltaic panels arranged horizontally side by side, a second photovoltaic assembly consisting of multiple second photovoltaic panels arranged horizontally side by side, and a common side beam. A first beam is provided below the first photovoltaic assembly, and the first photovoltaic panel is fixed to the first beam via multiple medium-voltage block assemblies; a second beam is provided below the second photovoltaic assembly, and the second photovoltaic panel is fixed to the second beam via multiple medium-voltage block assemblies; the first photovoltaic assembly and the second photovoltaic assembly are connected and fixed to the common side beam via multiple medium-voltage block assemblies; the medium-voltage block assembly includes a fastening bolt, a medium-voltage component, and a plastic wing nut, and the fastening bolt passes through the medium-voltage component and is threadedly connected to the plastic wing nut. However, existing plastic wing components are generally suitable for use when the nut block is a rectangular parallelepiped. However, the U-shaped fixing pad of the matching C steel is not equipped with a suitable plastic wing component, resulting in the two ends of the existing U-shaped fixing pad being bent upward and unable to be inserted into the existing plastic wing component. [Utility Model Content]

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a double-ring wing and photovoltaic component installation structure with a matching U-shaped fixing pad. When used with the matching U-shaped fixing pad, the U-shaped fixing pad will not fall off when the component is disassembled during later operation and maintenance, thereby reducing construction difficulties and improving construction efficiency.

[0004] The cam is hinged on the top of the U-shaped support frame, and the hinge has two opposite ends, and the two ends of the cam are hinged on the top of the U-shaped support frame, so that the cam can be locked.

[0005] Preferably, the support plate is a cross-shaped plate, and the cross-shaped plate includes a cross-connected transverse extension portion and a longitudinal extension portion.

[0006] Preferably, the length of the transverse extension portion is smaller than the length of the longitudinal extension portion, and the width of the transverse extension portion is larger than the width of the longitudinal extension portion. The upper ends of the two elastic ring sleeves are connected to the longitudinal extension portion, and the longitudinal ends of the longitudinal extension portion are correspondingly supported on the upper sides of the two inner flanges.

[0007] Preferably, the edge of the support plate is provided with a thickened structure.

[0008] Preferably, the elastic ring sleeve is a rectangular sheet structure, and the plane where it is located is perpendicular to the plane where the bottom edge of the U-shaped fixed pad is located; and / or, the double ring wings are injection molded parts.

[0009] Preferably, an arc transition structure is provided between the elastic ring sleeve and the support plate.

[0010] In addition, the utility model also provides a photovoltaic module installation structure, including a pressure block assembly, the pressure block assembly includes a pressure block, a U-shaped fixing pad and a pressure block bolt connecting the pressure block and the U-shaped fixing pad, the U-shaped fixing pad is connected to the double ring wing, and a through hole is provided on the support plate, and the pressure block bolt passes downward through the through hole and is connected to the U-shaped fixing pad.

[0011] Preferably, the pressing block includes a U-shaped portion and a pressing portion extending outward from both sides of a mouth of the U-shaped portion.

[0012] Preferably, the U-shaped fixing pad is provided with a screw hole that cooperates with the pressure block bolt.

[0013] Preferably, a gasket is provided between the pressing block bolt and the pressing block.

[0014] The utility model adopts the above technical solution, which has the following beneficial effects:

[0015] 1. Two elastic rings are spaced apart on both sides in the longitudinal direction. Due to their elasticity, they can be deformed. In this way, when assembled with the U-shaped fixing pad, the U-shaped fixing pad passes through the inner ring hole through the deformation of the elastic ring, thereby completing the assembly of the double ring wing and the U-shaped fixing pad with the help of the deformation of the elastic ring.

[0016] After the double ring wing and the U-shaped fixing pad are assembled together, the assembly is connected to the C-beam. Since the lateral width of the elastic ring sleeve is smaller than the distance between the inner sides of the two inner flanges, when the length of the U-shaped fixing pad is parallel to the C-beam, the U-shaped fixing pad and the two elastic ring sleeves are placed into the inner side of the C-beam from the upper opening, and then rotated 90 degrees to make the length of the U-shaped fixing pad perpendicular to the C-beam. Since the inner ring hole is located below the inner flange, the side and the inner flange form a limited fit, so that the U-shaped fixing pad is stuck into the C-beam, which is convenient for installation.

[0017] In addition, the support plate is supported on the upper side of the inner flange, fixing the height position of the U-shaped fixing pad, and through the inner ring hole and the side limit of the U-shaped fixing pad, it can not only prevent the U-shaped fixing pad from falling during installation, but also prevent the pad from falling when the components are disassembled during later operation and maintenance.

[0018] 2. The support plate is a cross-shaped plate, which not only has high structural strength but also has a large supporting area, so that the support plate can be reliably supported on the upper side of the inner flange.

[0019] 3. Since the length of the transverse extension is smaller than that of the longitudinal extension, and the width of the transverse extension is larger than that of the longitudinal extension, it is easy to distinguish the direction during installation. That is, when the longitudinal extension is parallel to the C-beam, place the combination of the double ring wing and the U-shaped fixing pad downward into the inner side of the C-beam.

[0020] 4. The edge of the support plate is thickened to increase structural strength. In addition, the elastic ring is a rectangular sheet structure, and the double ring wings are injection molded parts, which can reduce costs and have greater elastic deformation, which is conducive to assembly with the U-shaped fixing pad.

[0021] 5. In order to increase the strength of the connection part, an arc transition structure is provided between the elastic ring sleeve and the support plate.

[0022] 6. The pressing block includes a U-shaped portion and a pressing portion extending outward from both sides of the U-shaped portion. The U-shaped portion is inserted between the frames of two adjacent photovoltaic modules to fix the distance between the two adjacent photovoltaic modules. The pressing portion is pressed on the upper side of the frame. Under the action of the pressing block bolts, the frame of the photovoltaic module is pressed and fixed.

[0023] 7. The U-shaped fixing pad is provided with screw holes that match the clamping block bolts, so that the clamping block bolts can be tightened from above, which is convenient for operation from above.

[0024] 8. Since a gasket is provided between the pressing block bolt and the pressing block, the reliability of fastening can be increased to prevent loosening.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0034] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0035] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "horizontal," and "longitudinal" used below to indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be understood as limiting the utility model.

[0036] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0037] Reference Figures 1 to 5As shown, this embodiment provides a photovoltaic module mounting structure, including a clamp assembly, which is used to fix the photovoltaic module 6 to the C-beam 5. Here, the extension (length) direction of the C-beam is set to the horizontal direction. The clamp assembly includes a clamp 1, a U-shaped fixing pad 4, and a clamp bolt 2 connecting the clamp 1 and the U-shaped fixing pad 4. The C-beam 5 includes side panels 51 provided on opposite sides and inner flanges 52 formed by the free ends of the side panels being bent inwardly. The U-shaped fixing pad 4 includes a bottom edge 41 and side edges 42 provided on opposite sides.

[0038] In addition, a through hole 313 is provided on the support plate 31 , and the pressing block bolt 2 passes downward through the through hole 313 and is connected to the U-shaped fixing pad 4 .

[0039] To accommodate the U-shaped fixing pads and prevent them from falling during later maintenance and disassembly, a double-ring wing 3 is designed to be used with the U-shaped fixing pads 4. The double-ring wing 3 is assembled with the C-beam 5 and the U-shaped fixing pads 4. Once assembled, the side edges 42 and the inner flanges 52 form a retaining fit.

[0040] The double-ring wing 3 includes a support plate 31 supported on the upper side of the inner flange 52 and two elastic ring sleeves 32 disposed below the support plate 31 and correspondingly disposed on opposite sides. The two elastic ring sleeves 32 extend vertically downward from the bottom surface of the support plate and are disposed parallel to each other on both sides of the longitudinal direction. The two elastic ring sleeves 32 are located on the inner sides of the two inner flanges 52, and the lateral width W of the elastic ring sleeves 32 is less than the spacing L between the inner sides of the two inner flanges. The elastic ring sleeves 32 have an inner ring hole 321 near the bottom. The inner ring hole 321 is located below the inner flange 52, and the U-shaped fixing pad 4 passes through the inner ring holes 321 of the two elastic ring sleeves.

[0041] It is understandable that the two elastic ring sleeves 32 are in the shape of thin sheets and are arranged in parallel on both sides of the longitudinal direction to facilitate nesting with the U-shaped fixing pad 4 after elastic deformation. The specific structural form can be changed.

[0042] In the above technical solution, the two elastic ring sleeves are spaced apart on both sides in the longitudinal direction. Due to their elasticity, they can be deformed. In this way, when assembled with the U-shaped fixing pad, the U-shaped fixing pad passes through the inner ring hole through the deformation of the elastic ring sleeve, thereby completing the assembly of the double ring wings and the U-shaped fixing pad with the help of the deformation of the elastic ring sleeve.

[0043] After the double ring wing and the U-shaped fixing pad are assembled together, the assembly is connected to the C-beam. Since the lateral width of the elastic ring sleeve is smaller than the distance between the inner sides of the two inner flanges, when the length of the U-shaped fixing pad is parallel to the C-beam, the U-shaped fixing pad and the two elastic ring sleeves are placed into the inner side of the C-beam from the upper opening, and then rotated 90 degrees to make the length of the U-shaped fixing pad perpendicular to the C-beam. Since the inner ring hole is located below the inner flange, the side and the inner flange form a limited fit, so that the U-shaped fixing pad is stuck into the C-beam, which is convenient for installation.

[0044] In addition, the support plate 31 is supported on the upper side of the inner flange 52, fixing the height position of the U-shaped fixing pad, and through the inner ring hole and the side limit of the U-shaped fixing pad, it can not only prevent the U-shaped fixing pad from falling during installation, but also prevent the pad from falling when the components are disassembled during later operation and maintenance.

[0045] Specifically, the support plate 31 is a cross-shaped plate comprising a cross-connected transverse extension 312 and a longitudinal extension 311. A through-hole 313 is located at the center of the cross-shaped plate. The transverse extension 312 is longer than the longitudinal extension 311 and narrower than the longitudinal extension 311. The upper ends of the two elastic rings 32 are connected to the transverse extension 312, and the lateral ends of the transverse extension 312 are supported on the upper sides of the two inner flanges 52. Of course, the transverse and longitudinal directions here are still referenced after assembly.

[0046] Since the support plate is a cross-shaped plate, it not only has high structural strength but also has a large supporting area, so that the support plate can be reliably supported on the upper side of the inner flange; since the length of the transverse extension part is smaller than the length of the longitudinal extension part, and the width of the transverse extension part is larger than the width of the longitudinal extension part, it is also easy to distinguish the direction during installation, that is, when the longitudinal extension part is parallel to the C-beam, the combination of the double ring wing and the U-shaped fixing pad is placed downwardly into the inner side of the C-beam.

[0047] Further, such as Figure 4 and Figure 5 As shown, the edge of the support plate 31 is provided with a thickened structure 314 to increase structural strength. Furthermore, the double ring wing 3 is made of plastic, such as an injection molded part, and the elastic ring sleeve is a rectangular sheet structure that is not too thick. This reduces costs while also providing greater elastic deformation, facilitating assembly with the U-shaped fixing pad.

[0048] In order to increase the strength of the connection portion, an arc transition structure 33 is provided between the elastic ring sleeve 32 and the support plate 31 .

[0049] Referring to the prior art, the pressing block 1 includes a U-shaped portion 11 and a pressing portion 12 extending outward from both sides of the mouth of the U-shaped portion, wherein the U-shaped portion 11 is inserted between the frames of two adjacent photovoltaic components 6 to fix the spacing between the two adjacent photovoltaic components 6, and the pressing portion 12 is pressed on the upper side of the frame 61, and under the action of the pressing block bolt 2, the frame of the photovoltaic component 6 is pressed and fixed.

[0050] Furthermore, the U-shaped fixing pad 4 is provided with a screw hole that cooperates with the clamp bolt 2, so that the clamp bolt can be tightened from above, which is convenient for operation from above. A gasket 21 is provided between the clamp bolt 2 and the clamp 1 to increase the reliability of the fastening and prevent loosening.

[0051] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
