Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, specifically flexible photovoltaic support and photovoltaic modules. Background Technology

[0002] A prior art patent, CN116192012A, discloses a tracking flexible photovoltaic support system. This system includes vibration damping and stabilizing devices mounted on steel cables to support photovoltaic modules. Each device comprises four supporting arms, one end of which is mounted to the corresponding steel cable via a ball joint, and the other end of which is hinged to a module mounting base. A tension rod is slidably supported on a hollow column of the steel cable. A tension nut is screwed onto the threaded section of the tension rod, and this nut is rotatably supported on the hollow column. A tension worm gear is fixedly mounted on the tension nut, and a tension worm driven by a tension motor forms a worm gear pair with the tension worm. A steel cable crossbeam and a tracking worm gear are rotatably supported on the tension rod, and a tracking worm driven by a tracking motor forms a worm gear pair with the tracking worm. The tracking motor is mounted on a motor slide plate. This photovoltaic support system not only allows adjustment of the pitch angle of the photovoltaic modules but also ensures sufficient and stable tension in the steel cables, preventing damage to the photovoltaic modules from cable vibration.

[0003] However, the above-mentioned device still has some obvious defects in use: the device uses flexible cables to pull and fix multiple photovoltaic panels. This traction method is prone to insufficient tension in the middle of the cable. In practice, it has been found that the cable will be high on both sides and low in the middle under the weight of the photovoltaic panel, which will affect the tilt angle and power generation efficiency of the photovoltaic panel. Furthermore, this slack traction method will cause the cable to vibrate more in windy weather, which will seriously affect the stability of the overall structure behind the photovoltaic panel. Therefore, we propose flexible photovoltaic brackets and photovoltaic modules. Utility Model Content

[0004] The purpose of this invention is to provide flexible photovoltaic brackets and photovoltaic modules to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible photovoltaic support, comprising two sets of first hollow columns and two sets of second hollow columns, wherein a first flexible cable and a second flexible cable are respectively arranged between the two sets of first hollow columns and the two sets of second hollow columns, and multiple sets of photovoltaic panels are installed at equal intervals between the first flexible cable and the second flexible cable, wherein a suspension telescopic column is slidably arranged inside the first hollow column and the second hollow column, and a suspension cable is provided on the suspension telescopic column for suspending the middle part of the first flexible cable and the second flexible cable.

[0006] Preferably, the front and rear sides of the first hollow column and the second hollow column are connected by threaded telescopic assembly rods, and multiple sets of threaded assembly holes that cooperate with the telescopic assembly rods are evenly distributed on the suspended telescopic column along the length direction of the suspended telescopic column.

[0007] Preferably, both sides of the first hollow column are provided with threading holes for the first flexible cable and the second flexible cable to pass through, and a pre-tensioning traction seat is fixedly provided on one side of both the first hollow column and the second hollow column.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1

[0023] Please see Figure 1 and Figure 2This utility model provides a technical solution: a flexible photovoltaic support, comprising two sets of first hollow columns 1 and two sets of second hollow columns 2. A height difference exists between the first hollow columns 1 and the second hollow columns 2, resulting in a height difference between the first flexible cable 3 and the second flexible cable 4 connecting them. This causes the photovoltaic panel 5 installed on it to be in an inclined state. This arrangement allows for better conversion and utilization of light energy by the photovoltaic panel 5. The first flexible cable 3 and the second flexible cable 4 are respectively installed in a tensioned manner between the two sets of first hollow columns 1 and the two sets of second hollow columns 2. To address the insufficient tension in the middle of the first flexible cable 3 or the second flexible cable 4, a suspended telescopic column 6 is inserted into each of the first hollow columns 1 and the second hollow columns 2 in a lifting manner. The suspended telescopic column 6 is connected to the first flexible cable 3 and the second flexible cable 4 by a suspension cable 7 installed on it. Next, the upward traction force generated by the suspension cable 7 overcomes the downward tension on the first flexible cable 3 and the second flexible cable 4. The advantage of this arrangement is that it effectively solves the problem of insufficient tension in the middle of the first flexible cable 3 and the second flexible cable 4, thereby preventing excessive differences in tilt angle between the photovoltaic panels 5 and ensuring the stability of the structure in harsh environments. Multiple sets of photovoltaic panels 5 are installed at equal intervals between the first flexible cable 3 and the second flexible cable 4. The photovoltaic panels 5 are fixed in the first flexible cable 3 and the second flexible cable 4 by mechanical clamps or other connectors. Suspension telescopic columns 6 are slidably installed in the first hollow column 1 and the second hollow column 2. Suspension telescopic columns 6 are equipped with suspension cables 7 for suspending the middle of the first flexible cable 3 and the second flexible cable 4. The suspension telescopic columns 6 are connected to the first flexible cable 3 and the second flexible cable 4 by the suspension cables 7 installed on them.

[0024] Example 2

[0025] Please refer to Example 1. Figures 1-3 The first hollow column 1 and the second hollow column 2 are connected to telescopic mounting rods 10 by threads on both the front and rear sides. The telescopic mounting rods 10 have threaded grooves on their outer sides. Multiple sets of threaded mounting holes 11 that mate with the telescopic mounting rods 10 are evenly distributed on the suspended telescopic column 6 along the length of the suspended telescopic column 6. The working end of the suspended telescopic column 6 extends into the interior of the threaded mounting hole 11. By mates with the telescopic mounting rod 10 through the threaded mounting hole 11, that is, by screwing the working end of the telescopic mounting rod 10 into the threaded mounting hole 11 to fix the suspended telescopic column 6, the installation height of the suspended telescopic column 6 can be adjusted so that it can provide good traction and suspension for the first flexible cable 3 and the second flexible cable 4 of different lengths.

[0026] Both sides of the first hollow column 1 have through holes 13 for the first flexible cable 3 and the second flexible cable 4 to pass through. The ends of the first flexible cable 3 or the second flexible cable 4 also pass through the through holes 13 on both sides of the first hollow column 1 and the second hollow column 2 during the process. A pre-tensioning traction seat 14 is fixedly installed on one side of the first hollow column 1 and the second hollow column 2. The pre-tensioning traction seat 14 is fixed to the ground, and the base 8 is fixed to the ground. The sling 7 is connected to the first flexible cable 3 or the second flexible cable 4 through the cable clamping block 15. This arrangement makes the installation and removal of the sling 7 faster and the connection more reliable. The two ends of the first flexible cable 3 and the second flexible cable 4 are respectively pulled and connected to the pre-tensioning traction seat 14. The tension formed by the pre-tensioning traction seat 14 ensures effective support for the photovoltaic panel 5 installed on it.

[0027] A cable clamping block 15 is provided at the middle position of both the first flexible cable 3 and the second flexible cable 4. One end of the sling 7 is connected to the first flexible cable 3 and the second flexible cable 4 through the cable clamping block 15. The cable clamping block 15 is fixedly installed at the middle position of the first flexible cable 3 and the second flexible cable 4.

[0028] The interior of the suspension telescopic column 6 is provided with a cable hole 20, and the other end of the suspension cable 7 passes through the interior of the cable hole 20 and is fixed to the pre-tensioning traction seat 14.

[0029] The bottom of the first hollow column 1 and the second hollow column 2 are fixedly provided with a base 8, and a support beam 9 is fixedly provided between the first hollow column 1 and the second hollow column 2. The support beam 9 can increase the stability of the fixation between the first hollow column 1 and the second hollow column 2.

[0030] The suspended telescopic column 6 has a through-hole groove 12 inside, through which the first flexible cable 3 and the second flexible cable 4 pass. This ensures that the normal lifting and pulling of the first flexible cable 3 and the second flexible cable 4 is not affected during the lifting and lowering process of the suspended telescopic column 6. When the suspended telescopic column 6 moves upward, it can lift the suspension cable 7 upward, increasing the tension of the suspension cable 7.

[0031] Example 3

[0032] Please refer to Example 2. Figures 1-3The cable clamping block 15 consists of an upper cover 16 and a lower cover 17, which are fastened together by bolts. The upper cover 16 and the lower cover 17 are clamped onto the first flexible cable 3 and the second flexible cable 4, thereby fixing the cable clamping block 15. Threaded connection holes 18 are provided on both sides of the upper cover 16. Threaded posts 19 are threaded into the interior of the threaded connection holes 18. The interior of the threaded posts 19 has a groove. One end of the sling 7 passes through the groove and extends into the interior of the threaded connection hole 18. At this time, one end of the sling 7 is located between the threaded post 19 and the threaded connection hole 18. The threaded post 19 is used to tighten and fix one end of the sling 7 in the threaded connection hole 18, thereby fixing one end of the sling 7 to the upper cover 16. The end of the sling 7 is fixed to the threaded post 19. This installation method is reliable and facilitates quick assembly and disassembly, ensuring the reliability of the connection between the threaded post 19 in the sling 7 and the threaded connection hole 18. When disassembling the sling 7 connected to the cable clamping block 15, the threaded post 19 fixed in the threaded connection hole 18 is rotated outward and unscrewed, and then one end of the sling 7 fixed in the threaded connection hole 18 can be taken out.
