[0002] Photovoltaic flexible bracket is a new type of bracket structure in which photovoltaic components are installed on parallel prestressed cables. In the photovoltaic flexible bracket structure system, the reliable connection between the cable and the photovoltaic panel frame is crucial to the safety of the structure. At present, the commonly used connection method is to use a connector to fix it on the cable and bolt it to the bottom of the photovoltaic panel frame. However, when the photovoltaic panel is damaged by wind, the damage is often caused by the falling off of the connector bolts or the tearing of the screw holes in the panel frame, which is caused by excessive local stress. Related technologies attempt to increase the pressure block component to apply pressure to the top of the photovoltaic panel frame and reduce the local stress at the bolts, but the component stiffness is limited.

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0026] According to an embodiment of the present invention, a pressing block component for a photovoltaic flexible bracket includes a pressing block component 1 and a stiffening partition 14. The pressing block component 1 includes a pressing block body 11 and flanges 12 extending in a horizontal direction on both sides of the pressing block body 11. The flanges 12 are used to overlap with an outer frame 2 of a photovoltaic panel. The middle of the pressing block component 1 extends in a vertical direction. A groove 13 is arranged in the middle of the pressing block component 1. A screw hole 4 is arranged in the groove 13. The stiffening partition 14 is arranged in the groove 13 of the pressing block component 1 to improve the stiffness of the pressing block component 1. The stiffening partition 14 divides the groove 13 into two spaces. The pressing block component 1 fixes the photovoltaic panel outer frame 2 by abutting against the photovoltaic panel outer frame 2 through the flanges 12 on both sides of the pressing block body 11. The middle of the pressing block structure extends in the vertical direction to fill the gap between the two outer frames. The groove 13 in the middle of the pressing block is used to facilitate the entry of bolts and nuts to reduce the exposure of nuts. The reinforcing partition 14 is arranged in the groove 13 to improve the structural rigidity and reduce stress concentration.
[0027] The pressing block component for the photovoltaic flexible support according to the embodiment of the present invention has the advantages of good structural rigidity and not easy to deform.
[0028] In some embodiments, a plurality of stiffening partitions 14 divide the groove 13 into a plurality of spaces along the length direction of the pressing block component 1 .
[0029] Specifically, a plurality of stiffening baffles 14 are arranged in the groove 13, along the length direction of the pressing block component 1, that is, along the extension direction of the groove 13. The plurality of stiffening baffles 14 support the two groove walls of the groove 13, and can enhance the structural rigidity. It can be understood that the pressing block component 1 is a partially closed section, and the flanges 12 on both sides are open sections. The stiffening baffles 14 support the transition between the open section and the closed section.
[0030] In some embodiments, the width of the pressing block body 11 is smaller than the spacing between adjacent photovoltaic panel outer frames 2 so as to enter between two photovoltaic panel outer frames 2 .
[0031] Specifically, the width of the pressing block body 11 is smaller than the spacing between the two outer frames to facilitate the entry of the pressing block body 11, while the sum of the widths of the two flanges 12 and the pressing block body 11 is larger than the spacing between the two outer frames, so that the flange 12 at least partially blocks the overlap of the outer frame to achieve the abutment and fixation of the flange 12 to the outer frame.
[0032] In some embodiments, the stiffening partition 14 extends in the horizontal direction, and two ends of the stiffening partition 14 are respectively connected to the groove walls of the groove 13 .
[0033] Specifically, the stiffening partition 14 can be extended in the horizontal direction to abut against the two groove walls of the groove 13, so as to avoid the problem that the two photovoltaic outer frames squeeze the block component 1 after the block component 1 encounters strong winds, causing the groove 13 to deform, the top flange 12 of the block component 1 to separate from the outer frame, and the reinforcement failure.
[0034] In some embodiments, a side of the flange 12 that abuts against the photovoltaic panel outer frame 2 is provided with anti-slip textures to increase the friction between the pressing block component 1 and the photovoltaic panel outer frame 2 .
[0035] Specifically, the anti-skid pattern can be a sawtooth pattern, which can increase the friction between the flange 12 and the outer frame when it contacts the outer frame, making the two more secure. It can be understood that the anti-skid pattern can also be a stripe, dot or mesh pattern, the purpose of which is to increase the roughness of the contact surface to increase the friction. Optionally, a rubber layer or other high friction coefficient material is coated on the flange 12 or the outer frame to increase the friction. The rubber layer can also serve as a buffer layer to reduce the damage of the flange 12 to the outer frame.
[0036] In some embodiments, the cross section of the pressing block member 1 is approximately T-shaped.
[0037] Specifically, the cross-section of the pressing block component 1 is approximately T-shaped, and the pressing block component 1 extends between the two outer frames to increase the fixing effect of the pressing block component 1 on the outer frame. On the one hand, the flange 12 presses the outer frame to fix the outer frame, and on the other hand, the pressing block body 11 supports the side of the outer frame. The pressing block component 1 supports and fixes the outer frame from two directions, which can achieve a better fixing effect and ensure the effectiveness of the pressing block structure under high wind speeds.
[0038] In some embodiments, at least two screw holes 4 are disposed in the groove 13 .
[0039] Specifically, at least two screw holes 4 are provided in the groove 13, and a bolt is arranged in each screw hole 4. By increasing the number of screw holes 4 and bolts, the connection strength is increased to prevent shear damage or pull-out of the bolts.
[0040] According to the embodiment of the present invention, the pressing block reinforcement system for the photovoltaic flexible support includes a pressing block member 1, a bolt and a connector 3, a positioning groove 31 is arranged in the middle of the connector 3, a first bolt hole 32 is arranged on both sides of the connector 3, a screw hole 4 is arranged in the positioning groove 31 and corresponds to the screw hole 4 on the pressing block member 1, and the two ends of the bolt enter the screw hole 4 on the pressing block member 1 and the screw hole 4 in the positioning groove 31 respectively and are fixed by nuts respectively, and the connector 3 is connected and fixed to the photovoltaic panel outer frame 2 through the first bolt hole 32. The bolt passes through the first bolt hole 32 of the connector 3 and the hole on the photovoltaic panel outer frame 2 to fix the connector 3 to the outer frame. The cross section of the connector 3 is T-shaped, and the middle protrusion of the connector 3 is used to enter between the two photovoltaic panel outer frames 2, and the two ends of the connector 3 are used to be fixed to the outer frame.
[0041] The technical advantages of the pressing block reinforcement system for the photovoltaic flexible bracket according to the embodiment of the present invention are the same as the technical advantages of the pressing block component for the photovoltaic flexible bracket described above, and will not be repeated here.
[0042] In some embodiments, the width of the positioning slot 31 is greater than the diameter of the nut to accommodate the nut.
[0043] Specifically, the width of the positioning groove 31 is greater than the diameter of the nut, which can allow the nut to be located in the positioning groove 31 and prevent the nut from protruding out of the positioning groove 31. This can shorten the length of the bolt to a certain extent, improve the vertical tensile stiffness of the structure, and protect the nut.
[0044] In some embodiments, the positioning groove 31 of the connecting member 3 extends toward one side of the pressing block component 1 to shorten the length of the bolt.
[0045] Specifically, the bottom of the positioning groove 31 of the connecting member 3 protrudes from the connecting member 3 so that the distance between the screw hole 4 on the connecting member 3 and the screw hole 4 of the pressing block member 1 is shortened, and the length of the bolt can be shortened as a whole to improve the longitudinal tensile stiffness. Optionally, a stiffening partition 14 is arranged in the positioning groove 31 of the connecting member 3 to increase the structural stiffness, and the stiffening partition 14 can be multiple to divide the space in the positioning groove 31 into multiple.
