Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, and in particular to a component for reducing the tension friction of photovoltaic flexible support cables. Background Technology

[0002] While flexible photovoltaic (PV) supports have a wide range of applications, they can encounter challenges in complex terrain, such as undulating terrain, uneven pile foundation finishes, or angled terrain. This can result in the installed columns not being on the same horizontal plane, and slight bends between the component cables at the nodes of adjacent columns, as shown in the attached diagram. Figure 1 As shown, the presence of the bend causes the friction generated at the bend of the component cable to become frictional resistance during the tensioning process. This makes it easy for the component cable to get stuck at the node position of the column and beam during tensioning. Furthermore, the component cable is prone to wear and breakage under long-term external force, resulting in a short service life.

[0003] To address the aforementioned technical issues, Chinese utility model patent CN221974199U discloses a load-bearing cable fixing structure and a load-bearing cable support. This solution involves setting two support plates on a connecting plate, and then rotating a pair of rollers between the two support plates via bolts. The rollers can contact the upper and lower ends of the load-bearing cable, forming a rolling fit between the load-bearing cable and the rollers. This reduces friction and wear on the load-bearing cable, improving its service life. Simultaneously, an arc-shaped groove is provided on the support plate, and a U-bolt is slidably installed in the groove. The U-bolt can support and fix the load-bearing cable, and the position of the U-bolt in the groove can be adjusted to accommodate different angles of the load-bearing cable.

[0004] However, the above technical solution has the following problems: This solution mainly uses rollers to support the load-bearing cable (component cable). Although U-bolts can also play a certain supporting role, when the span of the component cable is large (several hundred meters), it means that the load on the component cable is greater, which will cause the U-bolts to loosen and then slide along the groove. Only the roller below can truly support the component cable. Since the contact surface of the roller is small, stress concentration is easy to occur, causing the roller to dent and deform downward. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a photovoltaic flexible support component to reduce the tension friction of the component cable, so as to solve the technical problem that the component cable fixing structure of the existing flexible photovoltaic support has low strength and is prone to deformation of the fixing structure due to large load in large span scenarios.

[0006] To achieve the above objectives, this utility model provides a component for reducing the tensile friction of photovoltaic flexible support cables, comprising:

[0007] The support plate is used to support the component cables;

[0008] The mounting structure is used to fix the bearing plate to the column beam;

[0009] Two sets of rolling support structures symmetrically arranged at both ends of the bearing plate along the span direction of the component cable, each set of the rolling support structure comprising:

[0010] A hoop, which is fixed to the bearing plate, has two support plates that are spaced apart from each other;

[0011] The first roller is rotatably disposed between the two support plates, and the first roller, together with the bearing plate and the support plates, forms the space for the constraint assembly cable;

[0012] The second roller is rotatably disposed at the end of the bearing plate and located below the first roller. When the component cable undergoes vertical displacement during tensioning, it makes rolling contact with at least one of the first and second rollers to reduce wear on the contact area between the component cable and the component.

[0013] As a preferred technical solution of this utility model, the installation structure includes a U-bolt and a U-bolt nut that is compatible with it. A first through hole is provided on the bearing plate, and a second through hole corresponding to the first through hole is provided on the column beam. During installation, the bolt body of the U-bolt passes through the first through hole and the second through hole in sequence and is fixedly connected with the U-bolt nut.

[0014] As a preferred technical solution of this utility model, the two bolts of the U-bolt and the arc-shaped connecting part located at the top of the two bolts form a limit on the component cable.

[0015] As a preferred embodiment of this utility model, the rolling support structure further includes:

[0016] The first rotating bolt has its shank portion passing through a first rotating bolt hole in the support plate of the hoop. The first roller is sleeved on the shank of the first rotating bolt. The hoop also has a positioning plate connected to the bottom end of the support plate.

[0017] The first pivot bolt nut is adapted to the first pivot bolt;

[0018] The positioning bolt has a shank that passes through a first positioning hole on the surface of the positioning plate, and the surface of the bearing plate has a second positioning hole that matches the first positioning hole.

[0019] As a preferred technical solution of this utility model, the two sets of rolling support structures are integrally formed so that the positioning plates of the two hoops are fixedly connected, thereby increasing the contact area with the bearing plate. A connecting cross plate is provided between the top ends of the support plates of the hoops. The rod of the U-bolt passes through the third through hole on the surface of the positioning plate and is connected to the first through hole and the second through hole in sequence.

[0020] As a preferred embodiment of this utility model, the rolling support structure further includes:

[0021] The second rotating bolt has a rod that passes through a second rotating bolt hole at the end of the bearing plate. The bearing plate has a roller mounting arc guide groove at the end that connects to the second rotating bolt hole. The second roller is sleeved on the rod of the second rotating bolt and is located in the roller mounting arc guide groove.

[0022] The second shaft bolt nut is adapted to the second shaft bolt.

[0023] As a preferred technical solution of this utility model, a component cable guide groove is provided at the upper end of the bearing plate and between the two roller mounting arc guide groove holes, and the component cable guide groove is adapted to the cross-sectional shape of the component cable.

[0024] As a preferred technical solution of this utility model, the two ends of the bearing plate are extended and bent downward to form a U-shaped groove structure that can fit the three sides of the column beam, so as to further prevent the bearing plate from moving relative to the column beam along the span direction of the component cable, thereby reducing the transmission of horizontal force.

[0025] As a preferred technical solution of this utility model, the ends of the bearing plate and the support plate are rounded to avoid the component cable being cut by the component during the tensioning process.

[0026] To better address the aforementioned technical problems, this utility model also provides a method for reducing the tensile friction of photovoltaic flexible support components, comprising the following steps:

[0027] Step 1: Fix the first roller to the upper end of the bearing plate using a hoop, and then install the second roller at the end of the bearing plate. The hoop is used to make the lower end of the first roller and the upper end of the bearing plate form a height not less than the cross-sectional dimension of the component cable.

[0028] Step 2: Use the installation structure to fix the bearing plate to the column beam;

[0029] Step 3: Pass the component cable through the space formed by the first roller, the hoop, and the support plate;

[0030] Step 4: During the tensioning process, when the component cable bends downward in the vertical direction, it will roll into contact with the second roller, and when the component cable bends upward in the vertical direction, it will roll into contact with the first roller, so as to reduce the wear of the component cable in the contact area with the component.

[0031] The beneficial effects of this utility model are as follows: By changing the layout of the rollers on the support plate, the component cable is supported by the support plate, while the rollers are only set on both sides of the support plate, which plays a rolling lubricating role for the component cable during tensioning, reducing the wear of the contact area between the component cable and the component. Since the support plate is directly and completely attached to the column beam, it is almost equivalent to the component cable being directly attached to the column beam. The contact area is much larger than the support area of ​​a single roller, the stress is more dispersed and less likely to concentrate, so the component is less likely to deform. While meeting the fixing requirements of component cables at different angles, it also takes into account sufficient structural strength. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0043] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0044] like Figure 1As shown, a photovoltaic flexible support component for reducing tension friction of the component cable includes: a bearing plate 2 for supporting the component cable 19; an installation structure for fixing the bearing plate 2 to the column beam 1; the component also includes two sets of rolling support structures symmetrically arranged at both ends of the bearing plate 2 along the span direction of the component cable 19, each set of rolling support structures including: a hoop 6 fixed to the bearing plate 2, the hoop 6 having two support plates arranged relatively spaced apart; a first roller 10 rotatably disposed between the two support plates, the first roller 10, the bearing plate 2, and the support plates together forming a space for constraining the component cable 19; and a second roller 16 rotatably disposed at the end of the bearing plate 2 and located below the first roller 10, which makes rolling contact with at least one of the first roller 10 and the second roller 16 when the component cable 19 undergoes vertical displacement during tensioning, so as to reduce wear of the component cable 19 in the contact area with the component.

[0045] The above technical solution can meet the fixing requirements of the module cable 19 at different angles, while simultaneously improving the support strength of the photovoltaic flexible support for the module cable 19, preventing deformation of the connection parts of the photovoltaic flexible support due to the long span and large load of the module cable 19. In use, the first roller 10 is first fixed to the upper end of the bearing plate 2 by the hoop 6, and then the second roller 16 is installed at the end of the bearing plate 2. The hoop 6 ensures that the lower end of the first roller 10 and the upper end of the bearing plate 2 form a height not less than the cross-sectional dimension of the module cable 19. Then, the mounting structure is used to... The carrier plate 2 is fixed to the column beam 1. One end of the component cable 19 is fixed to the side column beam. The other end of the component cable 19 passes through the space formed by the first roller 10, hoop 6 and bearing plate 2 on all components in sequence. After passing through all components, the other end of the component cable 19 is connected to the side column at the other end. Then, the component cable 19 is tensioned. When the component cable 19 bends downward in the vertical direction, it will roll into contact with the second roller 16. When the component cable 19 bends upward in the vertical direction, it will roll into contact with the first roller 10 to reduce the wear of the component cable 19 in the contact area with the component.

[0046] The improvement in structural strength of this invention is reflected in the following aspects: The layout of the second roller 16 on the bearing plate 2: This invention supports the component cable 19 by setting the bearing plate 2, while the second roller 16 is only set at the end of the bearing plate 2, mainly playing a rolling lubrication role for the component cable 19 during tensioning, thereby avoiding wear of the component cable 19. Since the bearing plate 2 is directly and completely attached to the column beam 1, it is almost equivalent to the component cable 19 being directly attached to the column beam 1. The contact area is much larger than the support area of ​​a single roller. Therefore, the stress is more dispersed and less likely to concentrate, so the component is less likely to deform and can withstand greater loads, making it suitable for application scenarios with larger spans.

[0047] like Figure 2 , Figure 3and Figure 4 As shown, in this embodiment, the installation structure includes a U-bolt 3 and a U-bolt nut 4 that is compatible with it. A first through hole 18 is provided on the bearing plate 2, and a second through hole 5 corresponding to the first through hole 18 is provided on the column beam 1. During installation, the bolt body of the U-bolt 3 passes through the first through hole 18 and the second through hole 5 in sequence and is fixedly connected to the U-bolt nut 4.

[0048] The above technical solution allows the bearing plate 2 to be installed on the column beam 1 in a detachable manner. In use, the bearing plate 2 is attached to the column beam 1, ensuring that the first through hole 18 on the surface of the bearing plate 2 is aligned with the second through hole 5 on the surface of the column beam 1. The shank of the U-bolt 3 is then passed through the first through hole 18 and the second through hole 5 from top to bottom. Finally, the U-bolt 3 is tightened and fixed using the U-bolt nut 4. To improve the connection strength, two U-bolts 3 can be provided.

[0049] like Figure 8 As shown, in this embodiment, the two bolts of the U-bolt 3 and the arc-shaped connecting part located at the top of the two bolts form a limit on the component cable 19.

[0050] By adopting the above technical solution, the installation position of the U-bolt 3 can be changed, and the U-bolt 3 can be used to limit the component cable 19 to prevent the component cable 19 from detaching from the bearing plate 2. At the same time, since the cross-section of the U-bolt 3 is cylindrical rather than sharp and relatively smooth, even if friction occurs between the U-bolt 3 and the component cable 19 during tensioning, it will not cause damage to the surface of the component cable 19.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the rolling support structure further includes: a first rotating shaft bolt 8, the rod of which passes through a first rotating shaft bolt hole 7 opened on the support plate of the hoop 6; a first roller 10 sleeved on the rod of the first rotating shaft bolt 8; the hoop 6 also has a positioning plate connected to the bottom end of the support plate; a first rotating shaft bolt nut 9, which is adapted to the first rotating shaft bolt 8; a positioning bolt 12, the rod of which passes through a first positioning hole 11 opened on the surface of the positioning plate; and a second positioning hole 13 adapted to the first positioning hole 11 opened on the surface of the bearing plate 2.

[0052] The above technical solution allows the first roller 10 to be rotatably positioned between the two support plates of the hoop 6. In use, the first roller 10 is first placed between the two support plates of the hoop 6, ensuring that the first roller 10 is aligned with the first pivot bolt hole 7 on the support plate. The first pivot bolt 8 is then passed through the first pivot bolt hole 7 and the first roller 10 in sequence until the first pivot bolt 8 emerges from the first pivot bolt hole 7 on the other support plate. The first pivot bolt nut 9 is then used to tighten the first pivot bolt 8, thus completing the installation of the first roller 10. The hoop 6 with the first roller 10 installed is then placed on the bearing plate 2, ensuring that the first positioning hole 11 on the surface of the hoop 6 is aligned with the second positioning hole 13 on the bearing plate 2. The positioning bolt 12 is then screwed into the first positioning hole 11 and the second positioning hole 13 in sequence, thus initially fixing the hoop 6 onto the bearing plate 2.

[0053] like Figure 8 As shown, in this embodiment, the hoop 6 of the two sets of rolling support structures is integrally formed so that the positioning plates of the two hoop 6 are fixedly connected, thereby increasing the contact area with the bearing plate 2. A connecting horizontal plate is provided between the top of the support plates of the hoop 6. The rod of the U-bolt 3 passes through the third through hole 22 opened on the surface of the positioning plate and is connected to the first through hole 18 and the second through hole 5 in sequence.

[0054] The above technical solution can further improve the connection stability between the hoop 6 and the bearing plate 2, and improve the pull-out resistance of the first roller 10. By integrating the two hoops 6 into an integrated structure, the number of components can be reduced, the installation steps can be significantly reduced, and the installation can be faster. At the same time, the two hoops 6 are a sheet metal part, which significantly improves the structural strength and makes them less prone to deformation. Secondly, when the two hoops 6 are connected as one, the positioning plates of the two are added, thereby increasing the contact area with the bearing plate 2. The positioning bolts 12 are more secure when fixed, and the secondary fixing with U-bolts 3 makes it even more secure, which helps to improve the connection strength. Other connection methods, such as welding, can also be used. Since the contact area is increased, the structural strength after welding is also higher, which helps to improve the pull-out resistance of the first roller 10 and the hoop 6.

[0055] like Figure 2 , Figure 4 and Figure 7 As shown, in this embodiment, the rolling support structure further includes: a second rotating shaft bolt 14, the rod of which passes through a second rotating shaft bolt hole 21 opened at the end of the bearing plate 2; the bearing plate 2 has a roller mounting arc guide groove 17 at its end that communicates with the second rotating shaft bolt hole 21; a second roller 16 is sleeved on the rod of the second rotating shaft bolt 14 and located in the roller mounting arc guide groove 17; and a second rotating shaft bolt nut 15, which is adapted to the second rotating shaft bolt 14.

[0056] The above technical solution allows the second roller 16 to be rotatably mounted at the end of the support plate 2. In use, the second roller 16 is first placed in the roller mounting arc guide slot 17 of the support plate 2, and the second rotating shaft bolt 14 is inserted through the second rotating shaft bolt hole 21 of the support plate 2 and passes through the second roller 16. Then, the other end of the second rotating shaft bolt 14 is tightened with the second rotating shaft bolt nut 15 to complete the connection. It should be noted that in order to ensure that the first roller 10 and the second roller 16 can rotate normally, the length of the roller mounting arc guide slot 17 and the distance between the two support plates in the hoop 6 must be greater than the length of the roller so that the roller can rotate freely without interference.

[0057] like Figure 4 and Figure 5 As shown, in this embodiment, a component cable guide groove 20 is provided at the upper end of the bearing plate 2 and between the two roller mounting arc guide groove holes 17. The component cable guide groove 20 is adapted to the cross-sectional shape of the component cable 19.

[0058] The above technical solution can easily position the component cable 19 in the component cable guide groove 20 on the bearing plate 2, preventing the component cable 19 from shifting horizontally under the action of external force.

[0059] like Figure 2 and Figure 5 As shown, in this embodiment, the two ends of the bearing plate 2 are extended and bent downward to form a U-shaped groove structure that can fit the three sides of the column beam 1;

[0060] The above technical solution can further prevent the bearing plate 2 from moving relative to the column beam 1 along the span direction of the component cable 19, thereby reducing the transmission of horizontal force.

[0061] like Figure 5 and Figure 6 As shown, in this embodiment, the ends of the bearing plate 2 and the support plate are rounded.

[0062] The above technical solution can prevent the component cable 19 from being cut by the sharp parts of the component during the tensioning process.

[0063] Working principle:

[0064] When using, such as Figure 5 and Figure 7 As shown, first, place the two second rollers 16 in the roller mounting arc guide slot 17 of the bearing plate 2, insert the second shaft bolt 14 through the second shaft bolt hole 21 of the bearing plate 2 and through the second roller 16, and then use the second shaft bolt nut 15 to tighten the other end of the second shaft bolt 14 to complete the installation of the second roller 16.

[0065] Next, as Figure 5 and Figure 6 First, place the first roller 10 between the two support plates of the hoop 6, ensuring that the first roller 10 is aligned with the first pivot bolt hole 7 on the support plate. Then, use the first pivot bolt 8 to pass through the first pivot bolt hole 7 and the first roller 10 in sequence until the first pivot bolt 8 comes out from the first pivot bolt hole 7 on the other support plate. Finally, use the first pivot bolt nut 9 to tighten the first pivot bolt 8 to complete the installation of the first roller 10. Place the hoop 6 with the first roller 10 installed on it on the bearing plate 2, ensuring that the first positioning hole 11 on the surface of the hoop 6 is aligned with the second positioning hole 13 on the bearing plate 2. Then, use the positioning bolt 12 to screw into the first positioning hole 11 and the second positioning hole 13 in sequence to initially fix the hoop 6 on the bearing plate 2.

[0066] Then, as Figure 8 , Figure 5 and Figure 3 As shown, place the bearing plate 2, on which the first roller 10 and the second roller 16 are installed, on the column beam 1. Use U bolts 3 to pass through the third through hole 22, the first through hole 18 and the second through hole 5 in sequence. Then use U bolt nuts 4 to initially tighten the U bolts 3, but do not tighten them too much to prevent the component cable 19 from not being able to pass through. This completes the installation of the column beam 1 on the column beam 1.

[0067] Finally, one end of the component cable 19 is fixed to the side column crossbeam, and the other end of the component cable 19 passes sequentially through the component cable guide grooves 20 on all the bearing plates 2. Simultaneously, it is ensured that the component cable 19 enters the hoop 6 and passes through the first roller 10 and the second roller 16. The U-bolt nuts 4 are tightened, ensuring that the lowest point of the arc-shaped connection between the two upper ends of the U-bolts 3 is not higher than the lowest point of the first roller 10 (so that when the component cable 19 bends upwards, the two U-bolts 3 and the two first rollers 10 can form four-way constraint forces on the component cable 19, resulting in stronger pull-out resistance). It should be noted that if the U-bolts 3 are used... Figure 1 , Figure 2 , Figure 3 and Figure 4 For the installation method, this operation is not required. When fixing the bearing plate 2 to the column beam 1, simply tighten the U-bolt nut 4. After passing through all components, the other end of the component cable 19 is connected to the side column at the other end. Then, tensioning of the component cable 19 is started. When the component cable 19 deviates vertically downward during the tensioning process, the component cable 19 will contact the second roller 16, thereby driving the second roller 16 to roll. When the component cable 19 deviates vertically upward during the tensioning process, the component cable 19 will contact the first roller 10, thereby driving the first roller 10 to roll, thereby reducing the wear of the contact area between the component cable 19 and the component.

[0068] It should also be understood that the components of this utility model have been structurally strengthened, as detailed below: (See attached diagram) Figure 8 As shown, when the angle of component cable 19 is downward, it can be regarded as component cable 19 directly acting on column beam 1. Due to the U-shaped structure of bearing plate 2, it can also be regarded as acting on three surfaces of column beam 1, namely the top surface and two side surfaces of column beam 1. At the same time, the second roller 16 is fixed in the bearing plate 2 by the second rotating shaft bolt 14 and the second rotating shaft bolt nut 15. The length of the second rotating shaft bolt 14 covers the entire width of the bearing plate 2, the bearing surface is larger, the stress is more dispersed, and it is not easy to concentrate, preventing the component from deforming due to large load. When the angle of component cable 19 is upward, the two U-shaped bolts 3 and the two first rollers 10 can form four-way constraint force on component cable 19, and the pull-out resistance is stronger.

[0069] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0070] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
