Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a purlin assembly and a photovoltaic support. Background Technology

[0002] Currently, some photovoltaic (PV) modules in the market are installed on the main shaft using open, U-shaped purlins. When subjected to lateral wind pressure or external loads, the U-shaped purlins, due to their non-closed cross-section, have insufficient bending and torsional stiffness. The two side flanges connecting two adjacent PV modules are prone to offset towards or away from each other, causing the purlin openings to shrink inward or expand outward, thus leading to damage to the PV support.

[0003] Therefore, it is necessary to provide a new purlin assembly and photovoltaic support to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a purlin assembly and photovoltaic support that can improve purlin strength and fixation effect, and effectively reduce purlin deformation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A purlin assembly includes a purlin and a reinforcing member. The purlin includes a base plate and two side plates, the two side plates being respectively connected to both ends of the base plate. The ends of the two side plates away from the base plate are bent toward each other to form wing plates.

[0007] The reinforcing member includes a mounting portion and a limiting portion. The two limiting portions are disposed at both ends of the mounting portion along a first direction. The mounting portion at least partially fits the two wing plates, and the side of the two wing plates that is far apart from each other at least partially abuts the limiting portion.

[0008] As a further improvement of the present invention, the reinforcing member further includes a main body portion, which is disposed on one side of the mounting portion along the second direction and at least partially adheres to the bottom plate and the two side plates, wherein the second direction is perpendicular to the first direction.

[0009] As a further improvement of this utility model, the main body, the mounting part, and the limiting part are integrally formed.

[0010] As a further improvement of this utility model, the mounting part is connected to the two wing plates by fasteners to install the reinforcing member onto the purlin.

[0011] As a further improvement of the present invention, the main body includes a bottom wall and two side walls located at both ends of the bottom wall. The ends of the two side walls away from the bottom wall are connected to the mounting part. The bottom wall is attached to the bottom plate, and the two side walls are attached to the two side plates.

[0012] As a further improvement of the present invention, the main body also includes an intermediate body and four reinforcing walls, wherein the intermediate body is fixedly connected to two side walls of the main body through the reinforcing walls.

[0013] As a further improvement of the present invention, each purlin is provided with at least two reinforcing members, and the two reinforcing members are respectively provided at both ends of the purlin.

[0014] To achieve the above objectives, the present invention also adopts the following technical solution:

[0015] A photovoltaic support includes a purlin assembly as described in any of the preceding claims, wherein the mounting portion of the reinforcing member and the two flanges of the purlin are respectively used to connect two adjacent photovoltaic modules.

[0016] As a further improvement of the present invention, the photovoltaic bracket further includes a main shaft, a mounting base, and a connector. The mounting base is fixedly connected to the purlin, and the connector is fixedly connected to the mounting base and at least partially conforms to the main shaft.

[0018] Compared to existing technologies, the beneficial effects of this utility model's purlin assembly and photovoltaic bracket are as follows: The purlin assembly includes purlins and reinforcing members. The reinforcing members include mounting parts and limiting parts. The mounting parts cover the purlin's flanges, increasing the contact area between the purlin and the photovoltaic module, reducing local stress, and thus reducing local buckling of the purlin and improving structural reliability. The two limiting parts are located at both ends of the mounting parts, respectively abutting against both sides of the purlin's flanges, thereby preventing the purlin opening from deforming outwards. This purlin assembly and photovoltaic bracket are dimensionally compatible and easy to install, improving on-site construction efficiency, with a stable structure and strong resistance to deformation.

[0029] Please see Figures 1 to 7 As shown, this embodiment discloses a photovoltaic support, including a purlin assembly. The purlin assembly includes a purlin 10 and a reinforcing member 20. The reinforcing member 20 is disposed on the purlin 10, and two adjacent photovoltaic modules 50 are integrally connected with the reinforcing member 20 and the purlin 10.

[0030] To facilitate the description of the embodiments of this utility model, a first direction and a second direction are used for auxiliary explanation, wherein the first direction is the width direction of the purlin 10, the second direction is the height direction of the purlin 10, and the first direction is perpendicular to the second direction.

[0031] Please see Figure 1 and Figure 2 As shown, the purlin 10 includes a base plate 101 and two side plates 102. The two side plates 102 extend vertically from both ends of the base plate 101. The ends of the two side plates 102 away from the base plate 101 are bent toward opposite sides to form two wing plates 103. The two wing plates 103 are used to fix two adjacent photovoltaic modules 50. The reinforcing member 20 includes a mounting part 2 and a limiting part 3. The two limiting parts 3 are disposed at both ends of the mounting part 2 along a first direction. The mounting part 2 at least partially fits against the two wing plates 103, and the opposite sides of the two wing plates 103 at least partially abut against the limiting parts 3. With this configuration, the two limiting parts 3 abut against the sides of the two wing plates 103, which can prevent the purlin 10 from deforming outward when subjected to lateral wind pressure or external load, thereby effectively enhancing the deformation resistance of the purlin 10. The mounting part 2 covers the wing plate 103 and also covers the opening of the purlin 10, so that the part of the purlin 10 where the reinforcing member 20 is set forms a closed section, thereby strengthening the overall structural strength of the purlin 10, increasing the contact area between the purlin 10 and the photovoltaic module 50, reducing local stress, thereby reducing the local buckling of the purlin 10 and improving structural reliability.

[0032] Please see Figure 1 and Figure 2 As shown, the purlin 10 is shaped like a "Z" and the reinforcing member 20 is T-shaped, with their shapes matching. In this embodiment, the reinforcing member 20 also includes a main body 1, which is disposed on one side of the mounting part 2 along the second direction and at least partially adheres to the bottom plate 101 and the two side plates 102 of the purlin 10. With this arrangement, the main body 1 adheres to the inner surface of the purlin 10, which can prevent the two side flanges 103 connecting the two adjacent photovoltaic modules from being squeezed and deformed inward when the purlin 10 is subjected to lateral wind pressure or external load.

[0033] In this embodiment, the main body 1, the mounting part 2, and the limiting part 3 are integrally formed. With this configuration, the reinforcing member 20 has high overall strength, and the connection between each part is smooth. As a result, the reinforcing member 20 is installed on the purlin 10, which also gives the purlin 10 high strength.

[0034] Please see Figure 2 As shown, the main body 1 is rectangular, including a bottom wall 11 and two side walls 12. The two side walls 12 extend vertically from both ends of the bottom wall 11, and the ends of the two side walls 12 away from the bottom wall 11 are connected to the mounting part 2. The bottom wall 11 is attached to the bottom plate 101 of the purlin 10, and the two side walls 12 are attached to the two side plates 102 of the purlin 10, respectively. The two ends of the mounting part 2 are attached to the two flanges 103 of the purlin 10, respectively. The middle part of the mounting part 2 is located directly above the main body 1, that is, above the opening of the purlin 10. Furthermore, the length of the mounting part 2 is equivalent to the sum of the widths of the bottom plate 101 and the two flanges 103 of the purlin 10. With this configuration, in the cross-section where the reinforcing member 20 is provided, the middle opening space of the purlin 10 is completely filled by the reinforcing member 20, effectively reducing the risk of the purlin 10 being squeezed and deformed inward.

[0035] Please see Figure 2 As shown, in this embodiment, the main body 1 further includes an intermediate body 13 and four reinforcing walls 14. The intermediate body 13 is located at the center of the main body 1 and is fixedly connected to the two side walls 12 of the main body 1 via the four reinforcing walls 14. Further, the bottom wall 11 and the two side walls 12 of the main body 1, together with the mounting part 2, form a rectangle, and the intermediate body 13 is fixedly connected to the four corners of the rectangle of the main body 1 via the four reinforcing walls 14. This arrangement further improves the strength of the reinforcing member 20, thereby improving the bending and torsional resistance of the purlin 10.

[0036] Please see Figure 1 , Figure 4 and Figure 5As shown, the mounting part 2 is connected to the two wing plates 103 by fasteners to install the reinforcing member 20 onto the purlin. Further, in this embodiment, the mounting part 2 is provided with mounting holes 21 for fasteners to pass through, and the mounting holes 21 are axially aligned with the through holes on the frame 501 of the photovoltaic module 50 and the through holes on the wing plates 103 of the purlin 10. The frames 501 of two adjacent photovoltaic modules 50 are integrally connected to the mounting part 2 of the reinforcing member 20 and the two wing plates 103 of the purlin 10. Bolts are used to sequentially pass through the frame 501, mounting part 2, and wing plates 103 from top to bottom and fix them at the other end, or sequentially pass through the wing plates 103, mounting part 2, and frame 501 from bottom to top and fix them at the other end, thus fixing the three together. This configuration simplifies the photovoltaic bracket installation process and improves on-site construction efficiency.

[0037] Please see Figure 1 , Figure 3 and Figure 5 As shown, each purlin 10 is provided with at least two reinforcing members 20. In this embodiment, the two reinforcing members 20 are respectively provided at both ends of the length direction of the purlin 10 to close the opening of the zigzag purlin 10 and further enhance the strength of the purlin 10.

[0038] Please see Figures 3 to 6 As shown, the photovoltaic bracket in this embodiment also includes a main shaft and a mounting base 30, with the mounting base 30 fixed between the purlin 10 and the main shaft. The mounting base 30 includes a base 301 and an extension 302 extending vertically from the base 301. The base 301 is fixedly connected to the purlin 10, and at least a portion of the side of the extension 302 away from the base 301 is adapted to and abuts against the main shaft. Further, the mounting base 30 has a symmetrical structure, with two extensions 302 extending vertically from the base 301 at both ends along the axial direction of the main shaft, and at least a portion of the lower contour of the extension 302 is adapted to and abuts against the main shaft. This arrangement facilitates the limiting connection between the purlin 10 and the main shaft.

[0039] Further, please refer to Figure 3 , Figure 5 and Figure 6 As shown, the mounting base 30 also includes a contact portion 303, which is parallel to the base 301. The contact portion 303 is positioned lower than the base 301, and at least partially abuts against the spindle. Specifically, the two contact portions 303 extend vertically from the middle of the two extension portions 302 toward opposite sides. This arrangement increases the contact area between the mounting base 30 and the spindle, thereby improving connection stability and support strength.

[0040] Please see Figures 3 to 7As shown, the photovoltaic bracket in this embodiment also includes a connector 40. The connector 40 is fixedly connected to the mounting base 30 and at least partially conforms to the main shaft. The connector 40 and the mounting base 30 cooperate to surround the main shaft. The connector 40 includes a surrounding portion 401 and a connecting portion 402. The surrounding portion 401 conforms to at least a portion of the outer wall of the main shaft, and the connecting portion 402 is fixedly connected to the mounting base 30. Further, the surrounding portion 401 is relatively flat to better conform to the main shaft for positioning, and the connecting portion 402 is cylindrical to enhance the connection strength with the mounting base 30. In this embodiment, the connector 40 is connected to both the mounting base 30 and the purlin 10. The outer periphery of the connector 402 is threaded. The connector 402 passes through the base 301 of the mounting base 30 and the bottom plate 101 of the purlin 10 from bottom to top. A nut is screwed into the connector 402 from one side of the bottom plate 101 and tightened to fix the purlin 10, the mounting base 30 and the connector 40 together. The connector 40 and the mounting base 30 hug the main shaft, so that the purlin 10 is fixedly connected to the main shaft. Thus, the photovoltaic module 50 can be relatively fixed on the main shaft and rotate with the main shaft.

[0041] In summary, compared with the prior art, the purlin assembly and photovoltaic support of this utility model have the following advantages: The purlin assembly includes a purlin 10 and a reinforcing member 20. The reinforcing member 20 includes a main body 1, a mounting part 2, and a limiting part 3. The main body 1 fits against the inner surface of the purlin 10 to prevent the purlin 10 from being squeezed and deformed inward. The mounting part 2 covers the flange 103 of the purlin 10, which can increase the contact area between the purlin 10 and the photovoltaic module 50, reduce local stress, and thus reduce the local buckling of the purlin 10 and improve structural reliability. The two limiting parts 3 are located at both ends of the mounting part 2 and abut against both sides of the flange 103 of the purlin 10, thereby preventing the purlin 10 from deforming outward. This purlin assembly and photovoltaic support are size-adaptable and easy to install, improve on-site construction efficiency, have a stable structure, and strong resistance to deformation.
