[0047] Flexible cable 400. Detailed Implementation

[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0049] The following is for reference. Figures 1-7 A photovoltaic tracking bracket 200 according to an embodiment of this application is described.

[0050] like Figure 1 As shown, the photovoltaic tracking bracket 200 includes multiple spaced support frames 300 and multiple flexible cables 400 for arranging photovoltaic modules 110.

[0051] In this embodiment, the support frame 300 includes a column 310, a crossbeam 320 and a support beam 330, and the crossbeam 320 is pivotally mounted on the column 310 about a pivot axis.

[0052] The crossbeam 320 is pivotally mounted on the column 310, allowing the crossbeam 320 to rotate around the pivot axis. The orientation of the upper surface of the crossbeam 320 can change with rotation. In actual use, by rotating the crossbeam 320 so that its upper surface faces the direction of direct sunlight, it is possible to track sunlight.

[0053] In this embodiment, the flexible cable 400 can be a steel strand, a steel wire rope, or a high-strength fiber rope, or other flexible ropes with strong load-bearing capacity and wear resistance.

[0054] like Figure 2 As shown, in this embodiment, the flexible cable 400 is connected between multiple crossbeams 320, and the multiple flexible cables 400 are spaced apart along the length direction of the crossbeams 320.

[0055] Flexible cables 400 are connected and tightened between multiple crossbeams 320, so that the flexible cables 400 are suspended in the air. Multiple flexible cables 400 are spaced apart along the length of the crossbeams 320, which facilitates the installation of photovoltaic modules 110 on multiple flexible cables 400. Each photovoltaic module 110 can be connected to at least two flexible cables 400, which improves the installation stability of the photovoltaic module 110. By rotating the crossbeams 320, the multiple flexible cables 400 are rotated, which in turn causes the photovoltaic module 110 to rotate and change its orientation.

[0056] It should be noted that when there are more than two support frames 300, each flexible cable 400 is connected to multiple support frames 300 in sequence. The flexible cable 400 is tightened by the crossbeams 320 of the two support frames 300 located at both ends. The crossbeam 320 located in the middle supports the flexible cable 400 and divides the flexible cable 400 into multiple installation segments along the length direction. This can adapt to various terrains and increase the overall span of the photovoltaic tracking bracket 200, thereby expanding the scale of photovoltaic power generation.

[0057] In this embodiment, the support beam 330 is connected to the crossbeam 320 and is slidably connected to the column 310 around the pivot axis.

[0058] When the flexible cable 400 is tightened, it will generate lateral force on each crossbeam 320. The lateral force increases when the crossbeam 320 is in motion, and the crossbeam 320 is under high load. By setting a support beam 330 to connect with the crossbeam 320 and the column 310, the support beam 320 is supported. At the same time, the support beam 330 can slide relative to the column 310 as the crossbeam 320 rotates, which improves the structural strength of the support frame 300 without affecting the rotation of the crossbeam 320.

[0059] According to the photovoltaic tracking bracket 200 provided in the embodiments of this application, a support beam 330 is set to connect the crossbeam 320 and make it slidably connected to the column 310 around the pivot axis. While not affecting the rotation of the crossbeam 320 around the pivot axis, it supports the crossbeam 320, which can offset part of the lateral force borne by the crossbeam 320 during operation, improve the structural strength, and can adapt to a larger photovoltaic power generation scale.

[0060] In some embodiments, the upper end of the column 310 may be provided with a bearing seat 315, and the lower end of the crossbeam 320 may be provided with a support seat 321. The bearing seat 315 and the support seat 321 are connected by a pin 316, a bushing 314 and a second bearing.

[0061] like Figure 3 , 4 As shown, in this embodiment, the bearing housing 315 is provided with downwardly extending bearing housing 315 fixing plates at both ends of the crossbeam 320 along its length. The two bearing housing 315 fixing plates are fixedly connected to the two sides of the column 310 along the crossbeam 320 along its length, thereby realizing the fixed installation of the bearing housing 315.

[0062] The support base 321 has upwardly extending support base fixing plates at both ends in the width direction of the crossbeam 320. The two support base fixing plates are fixedly connected to the two sides in the width direction of the crossbeam 320 to realize the fixed installation of the support base 321.

[0063] In this embodiment, the photovoltaic tracking bracket 200 may further include a support clamp 290, which includes a clamp body plate and two downwardly extending clamp flanges. The clamp body plate is located on the upper side of the crossbeam 320, and the two clamp flanges are correspondingly located outside the two support fixing plates. The clamp flanges and the support fixing plates are connected to the side of the crossbeam 320 in the width direction by bolts.

[0064] It is understandable that the axis of the pin 316 is the pivot axis. By setting the pin 316, the bushing 314 and the second bearing between the bearing seat 315 and the support seat 321, the rotational connection between the bearing seat 315 and the support seat 321 is realized, thereby allowing the crossbeam 320 to rotate around the pin 316, which can realize the stepless change of the tracking angle.

[0065] It should be noted that the specific model of the second bearing is not limited here. In this embodiment, the second bearing is a lubrication-free second bearing, which is highly durable, requires no frequent maintenance, and is easy to install.

[0066] like Figure 2 As shown, in some embodiments, both ends of the support beam 330 are connected to the crossbeam 320, and both ends of the support beam 330 are located on both sides of the pivot axis.

[0067] In this embodiment, the column 310 is connected to the middle section of the crossbeam 320. This connection method has good balance. Both ends of the support beam 330 are connected to the crossbeam 320, and the two ends of the support beam 330 are located on both sides of the pivot axis. The middle section of the support beam 330 is slidably connected to the column 310. This setting can accommodate the large-angle rotation of the crossbeam 320. The support beam 330 can play an effective supporting role at any angle. In addition, this setting can improve the load-bearing capacity of the two ends of the crossbeam 320 against vertical pressure.

[0068] In another embodiment, due to limited changes in the angle of sunlight, the crossbeam 320 does not need to rotate significantly. One end of the support beam 330 can be connected to the crossbeam 320, while the other end is suspended in the air. This ensures that when the crossbeam 320 rotates to a certain extreme position, the other end of the support beam 330 connects to the column 310. This provides support for the crossbeam 320, saves costs, and has a simple structure.

[0069] There are several ways to connect the support beam 330 and the column 310.

[0070] In some embodiments, the column 310 is provided with a sliding groove that extends through the length of the crossbeam 320, and the support beam 330 passes through the sliding groove and is slidably disposed within the sliding groove, wherein the sliding groove can limit the support beam 330 in the width direction of the crossbeam 320.

[0071] In some embodiments, the support frame 300 further includes a first bracket 311 and a connecting shaft 312. The first bracket 311 is connected to the column 310, and the connecting shaft 312 is connected to the first bracket 311. The support beam 330 is provided with an arc-shaped groove 331 arranged with the pivot axis as the axis, and the arc-shaped groove 331 is slidably engaged with the connecting shaft 312.

[0072] The first bracket 311 can support the support beam 330. By setting the connecting shaft 312 on the first bracket 311, when the crossbeam 320 rotates, it guides the support beam 330. When the crossbeam 320 is stationary, the connecting shaft 312 abuts against the arc groove 331 of the support beam 330, thereby supporting the crossbeam 320.

[0073] In this embodiment, the connecting shaft 312 includes a long bolt 312a, which is connected to the first bracket 311. A washer is fitted on the long bolt 312a. The support beam 330 is located between the washer and the first bracket 311. The washer and the first bracket 311 limit the support beam 330 in the width direction of the crossbeam 320, thereby achieving lateral support for the crossbeam 320.

[0074] like Figure 3 , 5As shown, in some embodiments, the support frame 300 further includes a first bearing 313, and the connecting shaft 312 is connected to the arc-shaped groove 331 through the first bearing 313.

[0075] The first bearing 313 is sleeved outside the long bolt 312a. By setting the first bearing 313 between the connecting shaft 312 and the arc groove 331, the frictional loss between the arc groove 331 and the connecting shaft 312 is reduced when the support beam 330 moves, thereby improving the durability of the support beam 330.

[0076] In this embodiment, the first bearing 313 is a plastic bearing, which is generally made of a self-lubricating material, is highly durable, and requires no frequent maintenance.

[0077] In some embodiments, the first bracket 311 is provided on the side wall of the column 310 facing the length direction of the beam 320.

[0078] In this embodiment, the support beam 330 is located on one side of the column 310 facing the width direction of the crossbeam 320. The first bracket 311 is located on the side wall of the column 310 facing the length direction of the crossbeam 320 to prevent interference with the movement of the support beam 330, and at the same time, it is convenient to set the connecting shaft 312 on the side of the column 310.

[0079] The first bracket 311 includes a main body and a flange. The main body is connected to the side wall of the column 310 facing the length direction of the crossbeam 320. The connecting shaft 312 passes through the flange and is fixed on the flange. The support beam 330 is limited by the flange and the first bearing 313 sleeved on the long bolt 312a.

[0080] In one example, a first bracket 311 is provided, and a first bracket 311 is provided on a side wall of the column 310 facing the length direction of the beam 320, and a connecting shaft 312 is provided corresponding to the first bracket 311.

[0081] In another example, there are two first supports 311, which are respectively located on the two side walls of the column 310 facing the crossbeam 320 along its length. There are two connecting shafts 312 corresponding to the two first supports 311. Both connecting shafts 312 are slidably engaged with the arc groove 331 of the support beam 330. The stability of the structure is improved by setting two first supports 311 and two connecting shafts 312.

[0082] like Figure 2 , 3 As shown, in some embodiments, the crossbeam 320 has opposing support beams 330 on both sides in the width direction.

[0083] The structural strength is further improved by setting two support beams 330, and the setting method of each support beam 330 is the same as the above embodiment of support beam 330.

[0084] In this embodiment, the connecting shaft 312 and the arc-shaped grooves 331 of the two support beams 330 are in sliding fit.

[0085] The first bracket 311 includes two flanges, which are respectively located at both ends of the main body facing the width direction of the crossbeam 320. The two flanges respectively support the inner side of the two support beams 330. The connecting shaft 312 passes through the two flanges to slide with the arc grooves 331 of the two support beams 330.

[0086] Among them, the long bolt 312a is fitted with a bushing 314 at the part between the two flanges, and the long bolt 312a is provided with two first bearings 313. The two first bearings 313 are respectively arranged at the positions of the two support beams 330. The bolt head and nut of the long bolt 312a respectively make the two first bearings 313 abut against the outside of the two support beams 330, and play a limiting role for the support beams 330.

[0087] like Figure 2 , 3 As shown, in some embodiments, the photovoltaic tracking bracket 200 further includes a connecting plate 210, and the two ends of the two support beams 330 are connected to the crossbeam 320 through the connecting plate 210.

[0088] In this embodiment, the two ends of the support beam 330 are connected to the side wall of the cross beam 320 in the width direction. Two connecting plates 210 are provided, corresponding to the two ends of the two support beams 330 respectively. The connecting plate 210 includes a main connecting plate and two downwardly extending connecting plate 210 flanges. The main connecting plate 210 is located on the upper side of the cross beam 320, and the two connecting plate 210 flanges are respectively located on the outer side of one end of the two support beams 330.

[0089] Bolts passing through the flange of the connecting plate 210 and the support beam 330 fix the flange of the connecting plate 210 and one end of the support beam 330 to the side of the crossbeam 320 in the width direction, thereby improving the structural strength at the connection between the support beam 330 and the crossbeam 320. Furthermore, the connecting plate 210 is installed over both ends of the support beam 330, which can reduce the weathering rate at both ends of the support beam 330 and improve its durability.

[0090] like Figure 3 As shown, in some embodiments, the upper end of the support beam 330 is connected to the side wall of the crossbeam 320 in the width direction, and the support beam 330 is provided with a protruding rib 332 on the side facing the crossbeam 320, and the protruding rib 332 is located below the crossbeam 320.

[0091] In this embodiment, the rib 332 is arranged in the vertical direction. When the crossbeam 320 is subjected to a large lateral force, the rib 332 can improve the torsional resistance of the support beam 330, thereby improving the crossbeam 320's ability to bear lateral forces.

[0092] In some embodiments, the upper end face of the rib 332 is arranged parallel to the lower end face of the crossbeam 320, and the upper end face of the rib 332 is spaced apart from the crossbeam 320.

[0093] The upper end face of the protruding rib 332 is set parallel to the lower end face of the crossbeam 320. When the crossbeam 320 is detached from the support beam 330, the upper end face of the protruding rib 332 can effectively support the lower end face of the crossbeam 320. If the connection between the crossbeam 320 and the support beam 330 is detached, the protruding rib 332 can provide some support for the crossbeam 320, preventing the crossbeam 320 from tilting directly to one side and damaging the photovoltaic module 110.

[0094] like Figure 2 , 3 As shown, in some embodiments, the photovoltaic tracking bracket 200 further includes a push rod 220 and a drive mechanism 230.

[0095] The push rod 220 is telescopic. One end of the push rod 220 is rotatably connected to the support beam 330, and the other end is rotatably connected to the column 310. The telescopic movement of the push rod 220 drives the support beam 330 to rotate, which in turn drives the crossbeam 320 to rotate.

[0096] In this embodiment, one end of the push rod 220 is connected to the side of the support beam 330 facing the crossbeam 320, and the other end of the push rod 220 is connected to the side wall of the column 310 facing the length direction of the crossbeam 320, so that the push rod 220 can push the crossbeam 320.

[0097] When there are two support beams 330, one end of the push rod 220 is located between the two support beams 330 and connected to the two support beams 330 respectively. The structure is more stable, the installation is simple, and the force is even when pushing.

[0098] In this embodiment, to increase the torque, one end of the push rod 220 is connected to the support beam 330 near the crossbeam 320. One end of the push rod 220 is located on the lower side of the crossbeam 320. When the crossbeam 320 falls off, the push rod 220 can also provide temporary support for the crossbeam 320 to prevent the crossbeam 320 from falling off directly.

[0099] It should be noted that the support beam 330 may not have a protruding rib 332 at the end connected to the push rod 220.

[0100] In this embodiment, the drive mechanism 230 is dynamically coupled to the push rod 220 to drive the push rod 220 to extend or retract.

[0101] The drive mechanism 230 is poweredly coupled to the push rod 220. The drive mechanism 230 drives the push rod 220 to extend and retract. The specific form of the drive mechanism 230 is not limited here. It can be a drive motor and a gear set that drive the push rod 220, or a linear motor that drives the push rod 220, or a drive motor and a worm gear that drive the push rod 220.

[0102] It is understandable that the specific form of the drive motor is not limited here; it can be a geared motor or other drive motors with high output torque.

[0103] In some embodiments, since the support frames 300 are flexibly connected, each support frame 300 is provided with a push rod 220 for pushing the crossbeam 320 on each support frame 300 to rotate.

[0104] In this embodiment, the photovoltaic tracking bracket 200 also includes a drive shaft 240, multiple push rods 220 are dynamically coupled to the drive shaft 240 through universal joints 250, and the drive mechanism 230 is dynamically coupled to the drive shaft 240 through universal joints 250.

[0105] Each push rod 220 is connected by a drive shaft 240, and the drive mechanism 230 drives the drive shaft 240 to move synchronously. This eliminates the need to set up a separate drive mechanism 230 for each push rod 220, resulting in a simple structure and cost savings.

[0106] The universal joint 250 connection can adapt to the characteristics of the flexible support. In different terrain environments or windy weather, there may be situations where the power output of each drive shaft 240 and drive mechanism 230 and the push rod 220 are not on the same axis. The universal joint 250 connection can ensure power transmission under various conditions.

[0107] Based on this implementation method, the drive mechanism 230 can be installed in the following ways:

[0108] Firstly, when there are two support frames 300, the drive mechanism 230 is set in either of the two support frames 300.

[0109] Secondly, when there are more than two support frames 300, the drive mechanism 230 is set on the support frame 300 in the middle position. At this time, the output torque of the drive mechanism 230 is transmitted to both sides along the transmission shaft 240, which is the shortest transmission path and the most labor-saving.

[0110] Understandably, in the second example, when the number of support frames 300 is odd, the drive mechanism 230 is set on the support frame 300 in the center position, and when the number of support frames 300 is even, the drive mechanism 230 can be set on either of the two support frames 300 in the center position.

[0111] like Figure 7 As shown, in some embodiments, the photovoltaic tracking bracket 200 also includes a clamping assembly 280.

[0112] The clamping assembly 280 is used to clamp the flexible cable 400 to prevent the flexible cable 400 from moving. The two ends of the flexible cable 400 are generally tensioned on two crossbeams 320 located at both ends and fixed by a tensioning device. When the number of support frames 300 exceeds two, the flexible cable 400 will be connected to the support frame 300 located in the middle.

[0113] In this embodiment, the crossbeam 320 is provided with a through hole that runs through the width of the crossbeam 320. The flexible cable 400 is correspondingly inserted into the through hole to support the flexible cable 400. However, due to the characteristics of the flexible support, the number and mass of the photovoltaic modules 110 arranged between the crossbeams 320 are different, which will cause the flexible cable 400 to move towards the heavier side and rub against the through hole, causing wear.

[0114] In this embodiment, the clamping component 280 is disposed on at least part of the crossbeam 320. The clamping component 280 clamps the flexible cable 400. By clamping the flexible cable 400 at both ends of the cable passing through the threading hole, the portion of the flexible cable 400 passing through the crossbeam 320 is relatively fixed to the crossbeam 320, thereby preventing the flexible cable 400 from moving in the threading hole.

[0115] Based on the above embodiments, the clamping component 280 can be configured in the following ways:

[0116] Firstly, such as Figure 7 As shown, the clamping assembly 280 includes a locking bracket 281 and two locking plates 282. The locking bracket 281 is located on the upper side of the crossbeam 320. The locking bracket 281 has clamping parts extending downward to the upper end of the wire hole at both ends of the crossbeam 320 in the width direction. The two locking plates 282 are correspondingly located on the lower side of the two clamping parts. The flexible cable 400 passes through the clamping parts and the locking plates 282. The clamping parts and the locking plates 282 are fastened together by bolts to clamp the flexible cable 400.

[0117] Secondly, the clamping assembly 280 includes two clamping members, which are respectively disposed at both ends of the wire hole, for clamping on the flexible cable 400 and adhering to the side wall in the width direction of the crossbeam 320 to prevent the flexible cable 400 from shifting.

[0118] like Figure 1 , 6 As shown, in some embodiments, the photovoltaic tracking bracket 200 also includes a cable-stayed device 260.

[0119] One end of the cable-stayed device 260 is connected to the column 310 located at the end, and the other end is used to connect to the ground.

[0120] By setting up the inclined cable device 260 to counteract the tension of the flexible cable 400 on the support frame 300 at both ends, the column 310 is prevented from tilting inward due to lateral force.

[0121] like Figure 6 As shown, in some embodiments, the photovoltaic tracking bracket 200 also includes a diagonal bracing device 270.

[0122] The diagonal bracing device 270 is located on the outer side of the two crossbeams 320 at the ends. Since the longer the crossbeam 320 is, the more easily the outermost part is subjected to stress and deformation, the diagonal bracing device 270 is added to form a triangular stable structure with the crossbeam 320, which enhances the structural stability and also accommodates the installation of larger components.

[0123] The photovoltaic tracking bracket 200 in this application has at least the following advantages:

[0124] I. It adopts a flexible connection structure, which is simple and low in cost. The span between the 300 support frames is large, which can adapt to various terrains and can be adapted to large-scale photovoltaic power generation.

[0125] Second, by setting up push rod 220, transmission shaft 240 and drive mechanism 230, a single drive mechanism 230 drives multiple crossbeams 320 to rotate, realizing daily tracking of the flexible support, increasing photovoltaic power generation efficiency, and the driving means are simple and low cost.

[0126] Third, by setting up a support beam 330, the structural strength of the crossbeam 320 is improved, the load-bearing capacity is higher, and it can be adapted to a larger power generation scale. Furthermore, the sliding connection between the support beam 330 and the column 310 does not affect the daily tracking function.

[0127] Fourth, by setting up the diagonal bracing device 270, a triangular stable structure is formed, which enhances the structural stability and can accommodate larger-sized photovoltaic power generation modules, thereby increasing the power generation scale.

[0128] This application also provides a photovoltaic power station 100.

[0129] like Figure 1 , 8 As shown, the photovoltaic tracking bracket 200 includes a photovoltaic tracking bracket 200 and multiple photovoltaic modules 110.

[0130] In this embodiment, the photovoltaic tracking bracket 200 is the photovoltaic tracking bracket 200 as described in any of the above embodiments. Multiple photovoltaic modules 110 are distributed on multiple flexible cables 400, and each photovoltaic module 110 is connected to at least two flexible cables 400 to ensure the installation stability of the photovoltaic module 110.

[0131] like Figure 8 As shown, in this embodiment, a connecting component 120 is provided between the photovoltaic module 110 and each flexible cable 400. In order to improve the utilization efficiency of the connecting component 120, the connecting component 120 is arranged between two adjacent photovoltaic modules 110, and two adjacent photovoltaic modules 110 are connected to the same flexible cable 400 through a connecting component 120.

[0132] It should be noted that the specific structure of the connecting component 120 is not limited here. In this embodiment, the connecting component 120 includes a connector and a locking piece 282. The connector includes a connecting part and a receiving part provided on both sides of the connecting part. The two receiving parts are used to receive two adjacent photovoltaic modules 110 respectively. The connecting part and the locking piece 282 cooperate to clamp and fix it on the flexible cable 400.
