The fastener 102 is adapted to part of the outer peripheral surface of the photovoltaic main beam 20 and is used to cooperate with the connecting plate 101 to fix the photovoltaic main beam 20 .

In this exemplary embodiment, by optimizing the connection assembly 10, a support portion 1011 is provided on the connection plate 101 to limit and support part of the outer peripheral surface of the photovoltaic main beam 20, and support ribs 1012 are provided to strengthen the connection plate 101 and strengthen the connection plate 101. The photovoltaic main beam 20 is limited. Considering that the photovoltaic main beam 20 is generally fixed horizontally, when the photovoltaic main beam 20 is fixed through the support portion 1011, the support rib 1012 and the fastener 102 on the connecting plate 101, the support portion 1011 and the support rib 1012 cooperates to limit the outer circumferential surface of the lower half of the horizontal photovoltaic main beam 20, and the fasteners 102 limit the outer peripheral surface of the horizontal photovoltaic main beam 20 located in the upper half. Thus, the connecting plate 101 and the fastener 102 cooperate to complete the overall connection and fixation of the photovoltaic main beam 20 . The design method based on the support part 1011 and the support rib 1012 increases the contact area with the photovoltaic main beam 20, which can reduce the stress concentration on the photovoltaic main beam 20 when fixing the photovoltaic main beam 20, is not easy to slip, is stable and reliable, and has a simple structure.

In some exemplary embodiments, as shown in FIG. 2 , FIG. 2 is a schematic structural diagram of a connecting plate according to an exemplary embodiment. In this exemplary embodiment, when the photovoltaic main beam 20 is a square main beam, the supporting surface includes: a planar support section 1011A adapted to the main beam side of the photovoltaic main beam 20 facing the connecting plate 101; A pair of curved surface limiting sections 1011B are adapted to the portion corresponding to the arc vertex angle (i.e., R angle) of any adjacent surface in the outer circumferential surface of 20. The pair of curved surface limiting sections 1011B are extended on both sides of the planar support section 1011A. side.

It should be noted that the R angle may not be set for the photovoltaic main beam 20 , but the photovoltaic main beam 20 of other shapes may be used. For example, the cross section of the photovoltaic main beam 20 is D-shaped, triangular, etc. Therefore, the main beam cross-sections that the connecting component 10 can be used for include but are not limited to small R-angle rectangular, D-shaped, or other polygonal cross-sections. The connecting component 10 can be designed according to the outline of the main beam of the respective cross-section.

In some exemplary embodiments, as shown in FIGS. 1 and 2 , considering the need to support the photovoltaic main beam 20 , the stress concentration of the photovoltaic main beam 20 on the supporting surface is reduced. In the length direction corresponding to the photovoltaic main beam 20, the support width range of the support surface is: 30mm-100mm.

In some exemplary embodiments, as shown in Figures 1 and 2, in order to ensure the limiting effect of the support ribs 1012 on the photovoltaic main beam 20 and the reinforcing effect of the support ribs 1012 on the strength of the connecting plate 101, in the corresponding photovoltaic main beam In the length direction of 20, the thickness range of the support rib 1012 is: 5mm-20mm.

It should be noted that the number of support ribs 1012 can be reasonably set on both sides of the support part 1011 according to actual needs. For example, two support ribs 1012 are provided on both sides of the support part 1011, two on each side. The supporting ribs 1012 are arranged in parallel along the length direction of the connecting plate 101 .

In some exemplary embodiments, as shown in FIG. 1 , the fastener 102 includes a U-shaped bolt 1021 and a locking nut 1022 , wherein the photovoltaic main beam is secured to the photovoltaic main beam by assembling the U-shaped bolt 1021 with the bolt hole on the connecting plate 101 . 20 fixed connections. During installation, first place the connecting plate 101 below the photovoltaic main beam 20; then use U-shaped bolts 1021 to install downward from the top of the photovoltaic main beam 20, so that the U-shaped bolts 1021 pass through the preset position of the connecting plate 101. Finally, the U-shaped bolts 1021 and the connecting plate 101 are tightened to the photovoltaic main beam 20 through the locking nuts 1022.

In some exemplary embodiments, as shown in FIGS. 1-2 , the middle part of the connecting plate 101 forms a first assembly structure, and both ends of the connecting plate 101 respectively form second assembly structures for hinged corresponding dampers 30 . By providing a first assembly structure in the middle of the connecting plate 101 and at least one second assembly structure at both ends of the connecting plate 101, after connecting the connecting plate 101 to the damper 30, the damper 30 can be raised to support the connecting plate.

In some exemplary embodiments, in order to prevent the stress of the photovoltaic main beam 20 on the supporting ribs 1012 from being too concentrated, when the thickness of the photovoltaic main beam 20 is small, the thickness of the supporting ribs 1012 can be appropriately increased. For example, when the photovoltaic main beam 20 adopts a cylindrical structure (such as a square tube, etc.), the wall thickness of the photovoltaic main beam 20 ranges from 2mm to 5mm, where the thickness of the supporting ribs 1012 is proportional to the wall thickness of the photovoltaic main beam 20. Inversely proportional.

Based on the supporting design of the bottom contact portion between the connecting component 10 and the photovoltaic main beam 20, the contact area with the photovoltaic main beam 20 is increased, the stress concentration of the main beam is reduced, and the photovoltaic main beam 20 is better protected. At the same time, there are a plurality of side support ribs 1012 on the connecting component 10, which can block the sides of the main beam and play a role in fixing the main beam, so that the damper 30 connector is not easy to slip with the main beam.

In this embodiment, the connecting plate 101 of the connecting assembly 10 has bolt holes for installing U-shaped bolts 1021 and connecting lugs 1013 (pin mounting holes) for installing the pin of the damper 30 . During installation, first place the connecting component 10 below the photovoltaic main beam 20, install the U-shaped bolts 1021 from above the photovoltaic main beam 20 and pass through the bolt holes of the connecting component 10. After adjusting the U-shaped bolts 1021, install it on the photovoltaic main beam. 20 is locked with the locking nut 1022 at the appropriate position; then place one end of the damper 30 between the two pin mounting holes of the damper 30 connector 1 and fix it with the pin, and connect the other end of the damper 30 to the fixed Base connection.

Since the connection assembly 10 has a support portion 1011 that supports and limits the photovoltaic main beam 20 and a support rib 1012 that limits the side of the photovoltaic main beam 20, the support portion 1011 can add the connecting plate 101 and the photovoltaic main beam during operation. The contact area of 20 can reduce the extrusion deformation of the photovoltaic main beam 20 when it is stressed. The support ribs 1012 corresponding to the sides of the main beam can be stuck on both sides of the photovoltaic main beam 20 to resist the gap between the photovoltaic main beam 20 and the connecting plate 101 torsional deformation.

It should be noted that in this embodiment, the width of the supporting portion 1011 of the connecting plate 101 of the connecting assembly 10, the thickness of the supporting ribs, and the number of supporting ribs can be selected and designed according to different main beam cross-sections.
