[0031] Please refer to Figures 1 to 10 As shown, the utility model discloses a flexible photovoltaic support, including a column 40, a beam 50 disposed at the top of the column 40, at least two ropes 20 fixedly connected to the beam 50, and a connecting assembly 30 for connecting a photovoltaic module 10 with the rope 20. The number of the column 40 and the beam 50 is at least two, and the column 40 and the beam 50 are correspondingly arranged. The column 40 is used to support the beam 50 and the rope 20. The beam 50 is disposed at the top of the column 40. The rope 20 and the beam 50 are fixedly connected, and the rope 20 is extended between adjacent beams 50. At least two ropes 20 can fix multiple photovoltaic modules 10, and two connecting assemblies 30 are correspondingly arranged on each rope 20, which are used to independently fix and connect a photovoltaic module 10 to the rope 20.

[0032] In this embodiment, the flexible photovoltaic support includes two ropes 20, and each photovoltaic module 10 has four connections with the two ropes 20, each connection is connected by a connection assembly 30, that is, each photovoltaic module 10 is connected to the two ropes 20 through four groups of connection assemblies 30. Figure 2 The photovoltaic assembly 10 includes a photovoltaic panel 101 and a frame 102 disposed outside the photovoltaic panel 101, and the connecting assembly 30 connects the frame 102 and the rope 20. The multiple photovoltaic assemblies 10 are independent of each other, and each group of connecting assemblies 30 is independent of each other, which can not only reduce the eccentricity of the flexible photovoltaic bracket, but also effectively reduce the deformation and tearing effect of the rope 20 twisting on the frame 102 of the photovoltaic assembly 10.

[0033] See also Figure 4 and Figure 5 The connecting assembly 30 includes a pressing block 1, a pad 2, a first fastener 3 and a second fastener 4. The pressing block 1 is connected to the photovoltaic assembly 10. There is a space between the pressing block 1 and the pad 2 for the rope 20 to pass through. The rope 20 is clamped between the pressing block 1 and the pad 2. The pressing block 1 is connected to the pad 2, thereby fixing the photovoltaic assembly 10 to the rope 20.

[0034] See also Figure 6 The pressing block 1 includes a pressing portion 11, a limiting portion 12 and a connecting portion 13. The limiting portion 12 connects the pressing portion 11 and the connecting portion 13. The pressing portion 11 and the connecting portion 13 are located on the same side of the limiting portion 12. The pressing portion 11 is used to press the top of the photovoltaic module 10, the limiting portion 12 is used to contact the side of the photovoltaic module 10, and the connecting portion 13 is connected to the bottom of the photovoltaic module 10 through the first fastener 3. The pressing portion 11, the limiting portion 12 and the connecting portion 13 enclose a space for accommodating the photovoltaic module 10. Furthermore, the pressing part 11 provides an upward limit for the photovoltaic assembly 10, especially when the back of the photovoltaic assembly 10 is affected by negative wind, the pressing part 11 limits the upward movement of the photovoltaic assembly 10 to prevent the photovoltaic assembly 10 from escaping from the pressing block 1; similarly, the connecting part 13 provides a downward limit for the photovoltaic assembly, and when the front of the photovoltaic assembly 10 is affected by external factors such as strong wind, the connecting part 13 can limit the downward displacement of the photovoltaic assembly 10, that is, the pressing part 11, the limiting part 12 and the connecting part 13 limit the photovoltaic assembly 10 in the accommodation space to prevent the photovoltaic assembly 10 from escaping. The side of a photovoltaic assembly 10 is pressed by the limiting part 12, and another adjacent photovoltaic assembly 10 is supported by the limiting part 12 of another group of connecting assemblies 30. There is no connection between the photovoltaic assemblies 10, so as to prevent the frame 102 of the photovoltaic assembly 10 from being torn due to vibration caused by strong wind.

[0035] In this embodiment, see Figure 6The projection of the pressing portion 11 along the height direction H of the pressing block 1 falls on the connecting portion 13 , and the pressing portion 11 presses against the frame 102 of the photovoltaic module 10 . The bottom of the frame 102 has a screw hole for the first fastener 3 to pass through.

[0036] See also Figure 6 There is a space for the rope 20 to pass through between the connection part 13 of the pressing block 1 and the pad 2, and the pad 2 and the connection part 13 are connected by the second fastener 4. The present application realizes the connection of the photovoltaic module 10 to the rope 20 through the pressing block 1, the pad 2, the first fastener 3 and the second fastener 4, which has a simple structure, low cost and strong practicality, and can reduce the self-weight eccentricity while ensuring the structural stability.

[0037] Continue to see Figure 6 The connecting portion 13 has a first connecting hole 131 for the first fastener 3 to pass through. The first connecting hole 131 is preferably a waist-shaped hole. Since the screw holes of the frame 202 of photovoltaic modules 10 of different specifications have different positions, by setting the first connecting hole 131 as a waist-shaped hole, it is convenient to adjust the position of the first fastener 3, so as to adapt to photovoltaic modules 10 of different specifications. The pad 2 has a receiving groove 230, and the receiving groove 230 is used to accommodate the rope 20. The receiving groove 230 is opposite to the first connecting hole 131, and the waist-shaped hole extends along the length direction of the receiving groove 230. The first fastener 3 is a hexagon socket bolt, which passes through the first connecting hole 131 and the screw holes of the frame 201 in sequence and is fastened with a nut.

[0038] In this embodiment, see Fig. 9 The first connection hole 131 is a countersunk hole, and the countersunk hole includes a recessed groove 1311 and a through hole 1312. The recessed groove 1311 is connected to the through hole 1312, and the recessed groove 1311 is opposite to the receiving groove 230. The first fastener 3 is a bolt, and the recessed groove 1311 is used to receive the head of the bolt. In this way, the head of the first fastener 3 will not extend into the receiving groove 230, avoiding interference with the rope 20.

[0039] The connecting portion 13 has at least two second connecting holes 132, and the at least two second connecting holes 132 are located on both sides of the width direction of the first connecting hole 131. Correspondingly, the pad 2 is provided with at least two third connecting holes 210, and the second fastener 4 is simultaneously penetrated through the second connecting hole 132 and the third connecting hole 210 corresponding to the second connecting hole 132. Preferably, the side of the connecting portion 13 opposite to the pad 2 is a flat plate structure, and when the rope 20 is arranged in the receiving groove 230, by tightening the second fastener 4, the connecting portion 13 and the pad 2 are close to each other, and the connecting portion 13 is tightly pressed above the rope 20, so that the rope 20 is firmly confined in the space between the receiving groove 230 and the connecting portion 13. In other embodiments, an open groove (not shown in the figure) adapted to the outer contour of the rope 20 may also be provided on the side of the connecting portion 13 opposite to the pad 2. The open groove and the accommodating groove 230 on the pad 2 together form a space for accommodating the rope 20. In addition, the open groove may also provide a limit for the installation of the rope 20, making the installation of the rope 20 more convenient.

[0040] In some embodiments, see Figures 6 to 8 The connecting portion 13 has two second connecting holes 132, which are located on both sides of the width direction of the first connecting hole 131. The backing plate 2 is provided with two third connecting holes 210, and the second fastener 4 passes through the second connecting hole 132 and the third connecting hole 210 in sequence and is fastened with the nut.

[0041] See also Figure 6 and Figure 7 The connecting portion 13 has a groove 133, which is formed by being recessed inward from the surface of the connecting portion 13 facing away from the sink 1311, and the groove 133 is connected to the second connecting hole 132, and the groove 133 is arranged around the outer periphery of the second connecting hole 132. The second fastener 4 is a bolt, and the groove 133 is used to receive the head of the bolt. Since the surface of the connecting portion 13 provided with the groove 133 is used to contact the photovoltaic module 10, the head of the bolt is arranged not to extend out of the groove 133 along the height direction H of the pressing block 1, thereby avoiding interference with the photovoltaic module 10.

[0042] For details, see Figure 6 and Figure 7 The second fastener 4 is a square bolt, and the head of the second fastener 4 includes a first side surface 411 and a second side surface 412, and the first side surface 411 is parallel to the second side surface 412. Correspondingly, the groove 133 includes a first groove wall 1331 and a second groove wall 1332, and the first groove wall 1331 is parallel to the second groove wall 1332. The first groove wall 1331 is used to abut against the first side surface 411, and the second groove wall 1332 is used to abut against the second side surface 412. In this way, the second fastener 4 is prevented from loosening.

[0043] See also Figure 8The pad 2 includes a first flat plate portion 21, a second flat plate portion 22, and an arc portion 23 connecting the first flat plate portion 21 and the second flat plate portion 22. The arc portion 23 is arranged to form a receiving groove 230. The first flat plate portion 21 and the second flat plate portion 22 are both provided with a third connecting hole 210. The arc portion 23 is provided with a convex tooth 231 protruding toward the receiving groove 230. The convex tooth 231 is used to prevent the rope 20 from moving, and the convex tooth 231 plays an anti-slip role.

[0044] The assembly process of the flexible photovoltaic bracket of the utility model is as follows: first, the second fastener 4 is inserted into the second connecting hole 132, and then the top and bottom of the photovoltaic component 10 are respectively contacted with the pressing part 11 and the connecting part 13, and the first fastener 3 is sequentially passed through the first connecting hole 131 of the pressing block 1 and the screw hole of the frame 201 of the photovoltaic component 10 and fastened with the nut. At this time, the photovoltaic component 10 is firmly connected to the pressing block 1, and then the rope 20 is installed in the receiving groove 230 of the pad 2, the pad 2 and the pressing block 1 are assembled, and the second fastener 4 is then passed through the third connecting hole 210 and fastened with the nut to lock the rope 20, thereby realizing the fixed connection between the photovoltaic component 10 and the rope 20.

[0045] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention.
