Description

Technical Field

[0001] This application relates to the field of photovoltaic mounting systems, and in particular to a highly stable structure for a flexible photovoltaic mounting system. Background Technology

[0002] Flexible photovoltaic support is a large-span, high-clearance, multi-span structure that uses rigid supports at both ends as fixing points to tension prestressed steel wire ropes or steel strands. The photovoltaic panels are fixed to the steel strands by clips, forming a large-span load-bearing flexible support system.

[0003] Since the steel strand is a flexible support relative to the rigid bracket and the photovoltaic panel is placed at an angle (the angled placement of the photovoltaic panel is mainly to obtain a good light tilt angle), when the photovoltaic panel is subjected to horizontal wind load, the horizontal wind load will generate a superimposed force in the horizontal and vertical directions on the photovoltaic panel, making the photovoltaic panel prone to superimposed motion of horizontal swaying and vertical swaying.

[0004] When the horizontal wind load is large, the vibration amplitude and force of the steel strands and photovoltaic panels are large. The two steel strands are prone to positional displacement, which can easily lead to damage to the connection structure between the steel strands and the photovoltaic panels, or even damage to the photovoltaic panels. Summary of the Invention

[0005] To improve the overall structural stability, this application provides a highly stable structure for flexible photovoltaic brackets.

[0006] This application provides a highly stable structure for a flexible photovoltaic support, which adopts the following technical solution:

[0007] A highly stable flexible photovoltaic support structure includes a load-bearing cable, two auxiliary cables, a photovoltaic panel, a force guide plate, and a force guide frame. The force guide frame includes two connecting arms, with the two ends of each arm designated as a first end and a second end, respectively. The first ends of the two connecting arms are connected together, and the connection between the two first ends is connected to the load-bearing cable via a first connecting structure. The second ends of the two connecting arms are connected to the auxiliary cables via second connecting structures. The photovoltaic panel and the force guide plate are fixed to the two connecting arms, respectively. The photovoltaic panel and the force guide plate are inclined and symmetrically arranged vertically. There is an air inlet / outlet gap between the proximal ends of the photovoltaic panel and the force guide plate.

[0008] By adopting the above technical solution, and by setting up a force guide plate and a force guide frame, the photovoltaic panel and the force guide plate are symmetrically arranged vertically, and the forces between the photovoltaic panel and the force guide plate can be transferred to each other. When the photovoltaic panel and the force guide plate are subjected to horizontal wind loads, the vertical components of the horizontal wind loads applied to the photovoltaic panel and the force guide plate are in opposite directions, that is, the two vertical components will cancel each other out, thereby reducing the vertical vibration of the overall structure and improving the stability of the overall structure.

The bottom of the first mounting groove is semi-circular, and the end face of the first mounting block is semi-circular. The first mounting block is detachably connected to the opening of the first mounting groove. The end face of the first mounting block and the bottom wall of the first mounting groove together clamp and fix the outer ring of the bearing. The second end is provided with an arc-shaped second mounting groove. The curvature center of the second mounting groove is located at the center of the bearing. The auxiliary cable passes through the second mounting groove. The second connecting structure is used to buffer and dampen the sliding movement of the auxiliary cable in the second mounting groove.

[0015] Optionally, the second connecting structure includes a second steel pipe, a second mounting block, a rubber block, and two buffer springs. The second steel pipe is sleeved and fixed to the auxiliary cable, and the rubber block is sleeved and fixed to the second steel pipe. The two side walls of the rubber block are respectively fitted to the arc-shaped groove wall of the second mounting groove. The second mounting block is detachably fixed to the groove opening of the second mounting groove. The buffer springs extend along the arc direction of the second mounting groove. One end of each of the two buffer springs is fixed to the bottom of the second mounting groove and the end face of the second mounting block, respectively.

[0016] Optionally, the second mounting block slides along the arc direction of the second mounting groove, and the second connection structure further includes an adjusting bolt for fixing the sliding position of the second mounting block.

[0017] Optionally, there is a gap between adjacent photovoltaic panels, and the first ends of the two connecting arms are hinged together with the hinge axis coinciding with the axis of the load-bearing cable; the first connecting structure includes a first steel pipe, which is sleeved and fixed to the load-bearing cable, and a vertically extending first mounting groove is provided at the bottom of the first end, the bottom of the first mounting groove is semi-circular, and the bottom walls of the two first mounting grooves are together in contact with the outer wall of the first steel pipe; the second end is provided with an arc-shaped second mounting groove, the curvature center of the second mounting groove is located at the center of the bearing, the auxiliary cable passes through the second mounting groove, and the second connecting structure is used to buffer and dampen the sliding movement of the auxiliary cable in the second mounting groove.

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will be described in further detail.

[0036] Example 1 discloses a highly stable structure for a flexible photovoltaic support, such as... Figure 1 , Figure 2 As shown, the highly stable structure of the flexible photovoltaic support includes a load-bearing cable 101, two auxiliary cables 102, a photovoltaic panel 410, a force guide plate 20, and a force guide frame 100. The two ends of the load-bearing cable 101 and the auxiliary cables 102 are respectively fixed to rigid supports on the ground (not shown in the figure), and the diameter of the load-bearing cable 101 is larger than the diameter of the auxiliary cables 102.

[0037] The force guiding frame 100 includes two connecting arms 1, with the two ends of each arm 1 designated as a first end 11 and a second end 12. In this embodiment, the first ends 11 of the two connecting arms 1 are integrally formed and connected. The force guiding frame 100 can be made of lightweight materials such as aluminum alloy or wood. The force guiding plate 20 can be made of lightweight board structures such as aluminum sheet, wood board, or foam board.

[0038] The photovoltaic panel 410 and the guide plate 20 are respectively fixed on the two connecting arms 1. The specific fixing method can be to use angle steel 103 or other connectors. The photovoltaic panel 410 and the guide plate 20 are both inclined and symmetrically arranged vertically. There is an air inlet and outlet gap between the near ends of the photovoltaic panel 410 and the guide plate 20.

[0039] In this embodiment, there is a gap between adjacent photovoltaic panels 410, that is, each photovoltaic panel 410 is set independently. In other embodiments, adjacent photovoltaic panels 410 can be fixed by a connection structure, that is, each photovoltaic panel 410 is connected as a force-bearing whole.

[0040] like Figure 2 , Figure 3 As shown, the connection between the two first ends 11 is connected to the load-bearing cable 101 through the first connecting structure 2, and the second ends 12 of the two connecting arms 1 are connected to the auxiliary cable 102 through the second connecting structure 3. That is, by setting the auxiliary cable 102, the load-bearing cable 101, the first connecting structure 2 and the second connecting structure 3, the auxiliary cable 102 and the load-bearing cable 101 are arranged relatively evenly on the force guide frame 100 to form a three-point support structure, thereby further improving the stability of the overall structure, and making the center of gravity of the overall structure fall into the middle of the three-point support structure, thereby further improving the stability of the overall structure.

[0041] Specifically, a vertically upward extending first mounting groove 111 is provided at the bottom of the connection position between the two first ends 11. The bottom of the first mounting groove 111 is semi-circular. The load-bearing cable 101 passes through the first mounting groove 111. The first connecting structure 2 includes a strip-shaped first mounting block 21. The end face of the first mounting block 21 is semi-circular. The first mounting block 21 is vertically inserted into the first mounting groove 111 through the opening of the first mounting groove 111. The end face of the first mounting block 21 and the bottom wall of the first mounting groove 111 together clamp and fix the load-bearing cable 101. The first mounting block 21 is also fixed to the opening of the first mounting groove 111 by fastening bolts 22 to ensure clamping stability.

[0042] To increase clamping stability, a rubber pad (not shown in the figure) can be provided at the clamping position between the first mounting block 21 and the bottom wall of the first mounting groove 111.

[0043] The bottom of the second end 12 is provided with a vertically upward extending second mounting groove 121. The load-bearing cable 101 passes through the second mounting groove 121. The second connecting structure 3 includes a strip-shaped second mounting block 31. The end face of the second mounting block 31 is semi-circular. The second mounting block 31 is vertically inserted into the second mounting groove 121 through the groove opening. The end face of the second mounting block 31 and the bottom wall of the second mounting groove 121 together clamp and fix the auxiliary cable 102. The second mounting block 31 is also fixed to the groove opening of the second mounting groove 121 by fastening bolts 22 to ensure clamping stability.

[0044] To increase clamping stability, a rubber pad can be provided at the clamping position between the second mounting block 31 and the bottom wall of the second mounting groove 121.

[0045] The installation sequence in this embodiment is as follows: first, the photovoltaic panel 410 is installed on the force guide frame 100; then, the force guide frame 100 is placed on the load-bearing cable 101 and the auxiliary cable 102; then, it is fixed to the load-bearing cable 101 and the auxiliary cable 102 respectively through the first connecting structure 2 and the second connecting structure 3; finally, the force guide plate 20 is fixed on the force guide frame 100.

[0046] Each photovoltaic panel 410 in the same row can be fixed with a force guide frame 100 and a force guide plate 20. Only the photovoltaic panel 410 in the middle of the same row can be equipped with a force guide frame 100 and a force guide plate 20, while the other photovoltaic panels 410 can be directly fixed to the load-bearing cable 101 and one of the auxiliary cables 102 through fasteners.

[0047] The implementation principle of this embodiment is as follows: by setting the force guide plate 20 and the force guide frame 100, the photovoltaic panel 410 and the force guide plate 20 are symmetrically arranged vertically, and the force between the photovoltaic panel 410 and the force guide plate 20 can be transmitted to each other. When the photovoltaic panel 410 and the force guide plate 20 are subjected to horizontal wind loads, the vertical component forces exerted by the horizontal wind loads on the photovoltaic panel 410 and the force guide plate 20 are in opposite directions, that is, the two vertical component forces will cancel each other out, thereby reducing the vertical vibration of the overall structure and improving the stability of the overall structure.

[0048] Secondly, by setting an air inlet and outlet gap, horizontal forward and horizontal reverse winds are allowed to pass through the guide plate 20 and photovoltaic panel 410, thereby canceling out the vertical forces of the forward and reverse winds.

[0049] Example 2 differs from Example 1 in that, as Figure 4 , Figure 5 As shown, the first connecting structure 2 includes a first steel pipe 1011, a bearing 1013, and a first mounting block 21. The first steel pipe 1011 is sleeved and fixed to the load-bearing cable 101. Specifically, the inner diameter of the first steel pipe 1011 is larger than the outer diameter of the load-bearing cable 101. The first steel pipe 1011 is sleeved on the outside of the load-bearing cable 101. There is a radial gap between the first steel pipe 1011 and the load-bearing cable 101. Furthermore, the first steel pipe 1011 is threadedly connected to a first clamping bolt 1012. The first clamping bolt 1012 extends radially along the first steel pipe 1011. The end of the first clamping bolt 1012 abuts against the outer circumferential surface of the load-bearing cable 101 to achieve the fixation between the first steel pipe 1011 and the load-bearing cable 101.

[0050] The inner ring of bearing 1013 is fitted and fixed to the first steel pipe 1011.

[0051] like Figure 5 As shown, a vertically extending first mounting groove 111 is provided at the bottom of the connection position between the two first ends 11. The bottom of the first mounting groove 111 is semi-circular, and the end face of the first mounting block 21 is semi-circular. The first mounting block 21 is inserted vertically upward into the first mounting groove 111 through the groove opening of the first mounting groove 111. The end face of the first mounting block 21 and the bottom wall of the first mounting groove 111 together clamp and fix the outer ring of the bearing 1013. The first mounting block 21 is also fixed to the groove opening of the first mounting groove 111 by fastening bolts 22 to ensure clamping stability.

[0052] To increase clamping stability, a rubber pad can be provided at the clamping position between the first mounting block 21 and the bottom wall of the first mounting groove 111.

[0053] like Figure 5 , Figure 6 As shown, the second end 12 is provided with an arc-shaped second mounting groove 121. The opening of the second mounting groove 121 extends through to the outer wall of the second end 12. The curvature center of the second mounting groove 121 is located at the center of the bearing 1013. The auxiliary cable 102 passes through the second mounting groove 121.

[0054] The second connecting structure 3 is used to buffer and dampen the sliding movement of the auxiliary cable 102 in the second mounting groove 121. Specifically, the second connecting structure 3 includes a second steel pipe 1021, a second mounting block 31, a rubber block 32, and two buffer springs 33. The second steel pipe 1021 is sleeved and fixed to the auxiliary cable 102. Specifically, the inner diameter of the second steel pipe 1021 is larger than the outer diameter of the auxiliary cable 102. The second steel pipe 1021 is sleeved on the outside of the auxiliary cable 102. There is a radial gap between the second steel pipe 1021 and the auxiliary cable 102. Furthermore, the second steel pipe 1021 is threaded with a second clamping bolt (not shown in the figure). The second clamping bolt extends radially along the second steel pipe 1021, and the end of the second clamping bolt abuts against the outer circumferential surface of the auxiliary cable 102 to achieve the fixation between the second steel pipe 1021 and the auxiliary cable 102.

[0055] The rubber block 32 is fitted and fixed to the second steel pipe 1021. The two side walls of the rubber block 32 are respectively fitted to the arc-shaped groove wall of the second mounting groove 121. That is, the second mounting groove 121 and the rubber block 32 are in a damped sliding fit, and the inner wall of the second mounting groove 121 can be made into a rough surface.

[0056] The second mounting block 31 is inserted into the second mounting groove 121 through the groove opening of the second mounting groove 121. The second mounting block 31 is also fixed to the groove opening of the second mounting groove 121 by fastening bolts 22. The buffer spring 33 extends along the arc direction of the second mounting groove 121. One end of the two buffer springs 33 is fixed to the bottom of the second mounting groove 121 and the end face of the second mounting block 31 respectively (this fixing method can be welding or other fixing structures). The other ends of the two buffer springs 33 abut against the two sides of the rubber block 32 respectively. In addition, the side of the rubber block 32 can also be provided with a groove (not shown in the figure). The end of the buffer spring 33 extends into the groove to improve the abutment stability.

[0057] Secondly, the cross-section of the second mounting groove 121 can be circular, which is adapted to the outer diameter shape of the buffer spring 33. The groove wall of the second mounting groove 121 will restrict the buffer spring 33 from detaching from the second mounting groove 121 along the axial direction of the auxiliary cable 102. The cross-section of the rubber block 32 can also be circular to fit the inner wall of the second mounting groove 121.

[0058] The force guide frame 100 is connected to the load-bearing cable 101 via the bearing 1013, allowing the force guide frame 100 to deflect at a certain angle around the axis of the load-bearing cable 101. The sliding cooperation between the rubber block 32 and the second mounting groove 121 ensures that the force guide frame 100 does not interfere excessively with the auxiliary cable 102 when it deflects at an angle.

[0059] The implementation principle of Example 2 is as follows: When a horizontal wind load is applied to the guide plate 20 and the photovoltaic panel 410, the vertical components of the horizontal wind load applied to the photovoltaic panel 410 and the guide plate 20 are in opposite directions. That is, the two vertical components are applied to the guide frame 100 and cancel each other out. During this process, since the two vertical components are difficult to be completely consistent, their magnitudes may be close or they may differ significantly. Therefore, after most of the components are canceled out, the resultant force of the two vertical components also forces the guide frame 100 to make a vertical offset movement. Furthermore, since the guide plate 20 is lighter than the photovoltaic panel 410, the center of gravity of the force system composed of the guide frame 100, the photovoltaic panel 410, and the guide plate 20 is biased upwards. Therefore, in reality, the force system composed of the guide frame 100, the photovoltaic panel 410, and the guide plate 20 will still be subjected to a certain vertical resultant force. In this embodiment, when the force system is subjected to a vertical resultant force and vibrates vertically, the vertical resultant force will force the guide frame 100 to deflect at a certain angle around the axis of the load-bearing cable 101. That is, the overall vertical vibration of the guide frame 100 is converted into the angular deflection motion of the guide frame 100, so as to amplify the displacement stroke of the guide frame 100 relative to the auxiliary cable 102. The large displacement stroke of the guide frame 100 relative to the auxiliary cable 102 causes the buffer spring 33 to compress and rebound significantly, and the inner wall of the second mounting groove 121 to slide with large damping relative to the rubber block 32. The buffer spring 33 can buffer the vertical resultant force, and the rubber block 32 converts the vibration kinetic energy into heat energy through frictional heat generation during the large stroke, so as to play an efficient shock absorption role, thereby reducing the impact of the vertical resultant force on the auxiliary cable 102, and thus improving the stability of the overall structure.

[0060] Example 3 differs from Example 2 in that, as Figure 7As shown, the second mounting block 31 slides along the arc direction of the second mounting groove 121, and the end of the second mounting block 31 facing the opening of the second mounting groove 121 is provided with a bevel 311; the second connecting structure 3 also includes an adjusting bolt 34, which is horizontally set and threadedly connected to the second end 12 of the connecting arm 1. The end of the adjusting bolt 34 extends into the second mounting groove 121 to abut against the bevel 311 of the second mounting block 31.

[0061] Rotate the adjusting bolt 34, and the end of the adjusting bolt 34 will press against the inclined surface 311 of the second mounting block 31, so as to force the second mounting block 31 to slide into the second mounting groove 121, thereby adjusting the position of the second mounting block 31 and the elastic force of the buffer spring 33 on the rubber block 32. In this way, the height position of the connecting arm 1 relative to the auxiliary cable 102 can be adjusted to adjust the angle of the overall force guide frame 100 relative to the horizontal plane, so as to keep the two connecting arms 1 symmetrically set on the horizontal plane as much as possible, or adjust the two connecting arms 1 to be symmetrically set relative to the wind direction according to the different wind directions on site.

[0062] Example 4 differs from Example 2 in that, as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the first ends 11 of the two connecting arms 1 are hinged together and the hinge axis coincides with the axis of the load-bearing cable 101. Specifically, both first ends 11 have a semi-circular convex plate 13 protruding from them. A first mounting groove 111 is provided on the convex plate 13. The opening of the first mounting groove 111 of one convex plate 13 is set upward, and the opening of the first mounting groove 111 of the other convex plate 13 is set downward. The bottom walls of the two first mounting grooves 111 are in contact with the outer wall of the first steel pipe 1011.

[0063] One side of the protruding plate 13 has a semi-circular stepped groove 131. The two protruding plates 13 are stacked along the length of the load-bearing cable 101. After stacking, the protruding plate 13 of one first end 11 is located in the stepped groove 131 of the other first end 11, and the protruding plate 13 and the stepped groove 131 are rotated around the axis of the load-bearing cable 101.

[0064] After the assembly is completed, the first mounting block 21 is slidably inserted into the first mounting groove 111. The bottom wall of the first mounting groove 111 and the end face of the first mounting block 21 are together attached to the outer wall of the first steel pipe 1011. The bottom wall of the first mounting groove 111, the end face of the first mounting block 21 and the outer wall of the first steel pipe 1011 can all be made into smooth surfaces, so that the protrusions 13 of the two connecting arms 1 can rotate relative to the first sliding tube 16 and rotate relative to each other without interference. Furthermore, the first clamping bolts 1012 of the first steel pipe 1011 can also be distributed on both sides of the protrusions 13 to limit the axial movement range of the protrusions 13 relative to the first steel pipe 1011.

[0065] The first connecting structure 2 also includes a pressure plate 14, which is fixed to the protruding plate 13 by fastening bolts 22. The pressure plate 14 is attached to the end face of the protruding plate 13 and is used to restrict the pressure plate 14 from disengaging from the stepped groove 131 along the axial direction of the load-bearing cable 101.

[0066] In this embodiment, the second connecting structure 3 is the same as the second connecting structure 3 in embodiment 2, both of which are used to buffer and dampen the sliding movement of the auxiliary cable 102 in the second mounting groove 121.

[0067] The implementation principle of Example 4 is as follows: When the horizontal wind load and the horizontal tilt angle between the photovoltaic panel 410 and the guide plate 20 are too large, or when the forces exerted by the horizontal wind load on the photovoltaic panel 410 and the guide plate 20 are too different, by setting the hinge of the two connecting arms 1, the forces on the photovoltaic panel 410 and the guide plate 20 will be applied to the corresponding connecting arms 1 respectively. The connecting arms 1 deflect at an angle, which will amplify the displacement stroke of the connecting arms 1 relative to the auxiliary cable 102. The large displacement stroke of the connecting arms 1 relative to the auxiliary cable 102 will cause the buffer spring 33 to compress and rebound significantly, and the rubber block 32 to slide with large damping relative to the inner wall of the second mounting groove 121. The buffer spring 33 can buffer the vertical resultant force, and the rubber block 32 converts the vibration kinetic energy into heat energy through frictional heat generation during the large stroke, so as to play an efficient shock absorption role, thereby reducing the impact of the vertical resultant force on the auxiliary cable 102, and thus improving the stability of the overall structure.

[0068] In the case of complex and variable horizontal wind load, a relatively independent connecting arm 1 is set up so that the forces on the photovoltaic panel 410 and the guide plate 20 can be buffered and damped separately, thereby reducing the occurrence of excessive vibration frequency and damage to the auxiliary cable 102 caused by the superposition of the forces of the photovoltaic panel 410 and the guide plate 20.

[0069] When the horizontal wind load is extremely large, the photovoltaic panel 410 and the guide plate 20 will deflect at a large angle, that is, the photovoltaic panel 410 deflects downward and the guide plate 20 deflects upward. At this time, the included angle between the photovoltaic panel 410 and the guide plate 20 is small, that is, the wind resistance of the overall structure is greatly reduced, so as to further reduce the impact of wind load on the stability of the overall structure.

[0070] Secondly, as the hinge point of the two connecting arms 1, the load-bearing cable 101 can also reduce its own vertical force and vertical swing by offsetting the vertical force to a certain extent, thereby improving the stability of the load-bearing cable 101.

[0071] Example 5, the difference between Example 5 and Example 4 is that, as Figure 12 As shown, the high stability structure of the flexible photovoltaic support also includes a force-guiding spring 17 and two sliding tubes 16. The disjoint ends of the two sliding tubes 16 are respectively hinged to two second ends 12. The proximal ends of the two sliding tubes 16 are fitted together with sliding fit. The sliding fit surfaces of the two sliding tubes 16 are provided with rubber sleeves 18, so that the sliding of the two sliding tubes 16 is damped.

[0072] The two ends of the guide spring 17 abut against the bottom wall of the two slide tubes 16 respectively, and the elastic force of the guide spring 17 will force the two slide tubes 16 to move away from each other.

[0073] The implementation principle of Example 5 is as follows: When the horizontal wind load is extremely large, the photovoltaic panel 410 and the guide plate 20 will deflect at a large angle, that is, the photovoltaic panel 410 deflects downward and the guide plate 20 deflects upward. The two sliding tubes 16 slide against each other with damping, and the guide spring 17 is compressed. At this time, the included angle between the photovoltaic panel 410 and the guide plate 20 is small, that is, the wind resistance of the overall structure is greatly reduced, so as to further reduce the impact of wind load on the stability of the overall structure. In addition, during this process, the buffering of the guide spring 17 and the damping sliding of the sliding tube 16 can achieve buffering and shock absorption of the two vertical components. Secondly, the vertical components of the photovoltaic panel 410 and the guide plate 20 are also applied to the guide spring 17 together, that is, the two vertical components are canceled to a certain extent at the guide spring 17, thereby reducing the impact of the vertical components on the overall structure.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
