[0020] As Figures 1-4 The utility model discloses a large span photovoltaic flexible support, include: fixed frame 1 and suspension cable 2, suspension cable damping assembly and suspension cable pressurizing assembly.

[0021] As Figures 1-4 The utility model discloses a large span photovoltaic flexible support, include: fixed frame 1 and suspension cable 2, suspension cable damping assembly and suspension cable pressurizing assembly.

[0022] As Figure 3As shown, both the first and second drop components 5 and 7 are made of stainless steel. In actual use, the appropriate material can be selected based on the number of photovoltaic panels installed on the suspension cable 2 and the load-bearing capacity of the suspension cable 2 itself. At the same time, the weight and installation position of the first drop component 5 can be determined. Both the first and second drop components 5 and 7 are spherical in shape to reduce wind resistance and the probability of the first drop component 5 swaying due to wind. The spherical shape also reduces the adhesion of external impurities.

[0023] like Figures 1-4 As shown, an adjusting disc 12 is slidably installed inside the limiting sleeve 10. A groove is formed on the inner wall of the limiting sleeve 10. A slider is installed on the adjusting disc 12, and the slider is slidably connected to the groove. The adjusting disc 12 has a T-shaped structure with a threaded groove on its top. A threaded cylinder 14 is rotatably installed on the limiting sleeve 10. An external thread is provided on the outer side of the threaded cylinder 14, and the bottom end of the threaded cylinder 14 extends into the threaded groove. The external thread is threadedly connected to the threaded groove. A pull rope 6 passes through the threaded cylinder 14 and the adjusting disc 12 and is movably connected to both. A rubber sleeve can be installed inside the threaded cylinder 14. The rubber sleeve contacts the pull rope 6 and forms a compression, thereby reducing the entry of external impurities into the threaded cylinder 14. A connecting spring 13 is installed at the bottom end of the adjusting disc 12. The connecting spring 13 contacts the lowering part 7. The connection spring 13 allows for... When the second lowering component 7 is subjected to the upward pulling force from the first lowering component 5, a reverse force can be applied to the second lowering component 7. This force, together with the weight of the second lowering component 7 itself, resists the upward pulling force from the first lowering component 5, thereby allowing the first lowering component 5 to return to a stable state more quickly. As can be seen from the above, the height of the connecting spring 13 can be adjusted using the threaded cylinder 14 and the adjusting disc 12, thereby determining the force exerted by the connecting spring 13 on the second lowering component 7. In summer or winter, the suspension cable 2 expands or contracts due to the influence of the external environment. Therefore, the height of the connecting spring 13 needs to be adjusted according to the season to ensure the pulling force of the second lowering component 7 on the first lowering component 5. For example, the height of the connecting spring 13 can be increased when the temperature is low, and decreased when the temperature is high.

[0024] In this embodiment, two suspension cables 2 are provided on the photovoltaic flexible support. The suspension rope 4 is arranged in a three-way shape. The two ends of the suspension rope 4 are connected to two cable clamps 3 respectively. The two cable clamps 3 are equipped with abutment rods 8. By setting the abutment rods 8, the two suspension cables 2 can be prevented from being pulled by the suspension rope 4 and generating a force that moves them closer to each other, thereby causing the suspension cables 2 to deform.

[0025] In use, the falling piece one 5 is installed on the two corresponding suspension cables 2 through the hanging rope 4 and the cable hoop 3, the falling piece one 5 applies a downward force to the suspension cable 2, when the suspension cable 2 shakes due to the influence of the external environment, the downward force effectively absorbs and disperses the energy generated in the shaking process of the suspension cable 2, thereby reducing the amplitude of the shaking, and also makes the suspension cable 2 recover to a stable state more quickly, ensuring the smoothness of the use of the photovoltaic flexible support;

[0026] In use, the falling piece one 5 can be used synchronously with the suspension cable pressure assembly, that is, two falling piece twos 7 are connected on the falling piece one 5 through the pull rope 6, the downward force of the two falling piece twos 7 can increase the downward force on the suspension cable 2, and the downward force of the two falling piece twos 7 acting on the falling piece one 5 can also increase the stability of the falling piece one 5, and the two falling piece twos 7 are arranged on the two sides of the falling piece one 5, the falling piece two 7 can only move up and down under the action of the limiting sleeve 10, that is, the falling piece two 7 is only affected by its own gravity and the upward force brought by the pull rope 6, and is not affected by the force in other directions, so the pulling direction of the falling piece two 7 on the falling piece one 5 is relatively stable, when the falling piece one 5 shakes due to the influence of the suspension cable 2, the shaking of the falling piece one 5 can be offset and reduced by the pulling force of the falling piece two 7 until it is kept stable, thereby indirectly ensuring the stability of the suspension cable 2.

[0027] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to this, various changes can be made within the knowledge range possessed by the person skilled in the art without departing from the purpose of the utility model.
