Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In existing technologies, photovoltaic support structures mainly enhance their wind and vibration resistance by increasing the cross-sectional area of ​​the support components, increasing the number of cables, or using triangular structures to strengthen the connections. However, these methods often increase the weight and cost of the support structures, and some methods lead to increased rigidity of the support structures, which is not conducive to absorbing wind load energy and may even aggravate vibration.

[0025] To address the aforementioned defects in photovoltaic mounting systems during use, please refer to [link / reference needed]. Figures 1-7This utility model provides a load-bearing and windproof integrated fish-belly type damping device. The photovoltaic array formed by this damping device can absorb wind-borne energy and effectively reduce the vibration amplitude of the support. This damping device is based on multiple sets of damping mechanisms arranged side by side. Each damping mechanism includes a pair of side columns 1 and a central column 2 positioned between the side columns 1. One-way jacking piles 101 and two-way jacking piles 201 are respectively installed at the upper ends of the side columns 1 and the central column 2. A downwardly protruding load-bearing cable 5 is fixedly installed between the two-way jacking piles 201 and the two one-way jacking piles 101. Multiple equidistant trusses 6 are installed on the load-bearing cable 5, with 5-8 trusses 6, the height of which gradually decreases from the center to the sides. The load-bearing cable 5 forms a downwardly convex arc through the trusses 6, which enhances the resistance of the entire damping mechanism. Damping steel wire ropes 7 are installed on the inner side of the one-way jacking pile 101 and at both ends of the two-way jacking piles 201. A pulley hanger 8 is installed at the lower end of the damping steel wire rope 7. An upwardly protruding damping steel wire rope 9 is fixedly installed between two pulley hangers 8 on the same side. The second type of damping steel wire rope 9 is installed on multiple trusses 6 by fasteners 10. The second type of damping steel wire rope 9 can protrude upward through the truss 6, and the two ends of the second type of damping steel wire rope 9 are respectively fixedly installed with counterweights 11 through two pulley hangers 8. The counterweights 11 are set perpendicular to the ground, and the height of the counterweights 11 from the ground is the amount of downward deformation of the second type of damping steel wire rope 9 under the maximum wind load. The first type of damping steel wire rope 7 is rigidly connected to the central column 2 with a reserved length so that it can form a triangular hanging under the action of the second type of damping steel wire rope 9 and the counterweights 11. The second type of damping steel wire rope 9 is non-rigidly connected to the first type of damping steel wire rope 7 through the pulley hanger 8, and is suspended by the counterweights 11 under the action of the pulley hanger 8, thus forming a flexible triangular structure that can produce a damping effect according to the magnitude of wind vibration. This structure can not only reduce the load on the equipment, but also effectively reduce the amplitude of vibration and enhance the stability of the equipment.

[0026] To ensure the overall stability of the photovoltaic array, anchor piles 3 are installed on the outer side of the side columns 1. Anchor piles 3 and unidirectional top piles 101 are connected by anchors and inclined cables 4. The two side columns 1 are arranged in a north-south direction, and the central column 2 is arranged side by side with the two side columns 1. When wind acts on the photovoltaic array, it will generate a lateral force that attempts to pull the array off course. First, the anchor piles 3 in the north-south direction, the inclined cables 4, the load-bearing cables 5, and the damping steel wire ropes 9 together form a support frame to counteract the lateral force generated by the wind and prevent the array from tilting. Second, the load-bearing cables 5 and the damping steel wire ropes 9 can absorb some of the energy brought by the wind and reduce the vibration of the array. Finally, the counterweight 11 applies a downward pull on the damping steel wire ropes 9 through the effect of gravity to balance the upward force brought by the wind and ensure that the array always maintains vertical stability.

[0027] Since the load-bearing cable 5 and the damping wire rope 9 need to be supported by the truss 6 to form a convex shape, it is necessary to ensure the stability of the truss 6. Therefore, multiple rows of equally spaced support columns 12 are also provided. Multiple support columns 12 in the same row are arranged in the east-west direction, and the upper end of the support column 12 is fixedly installed with a support beam 13. A pair of component cables 14 are fixedly installed on multiple support beams 13. The truss 6 is installed on the component cables 14 by fasteners 10. In order to ensure the stability of the support column 12, a pair of anchor piles 15 are also provided on one side of the support column 12. The anchor piles 15 and the support beam 13 are connected by an anchor with a stay cable 16. This can support the component cables 14, and the component cables 14 can support the truss 6, thereby ensuring the stability of the truss 6 and the wind resistance of the load-bearing cable 5 and the damping wire rope 9.
