Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a flexible photovoltaic bracket. Background Art

[0002] After years of rapid development of the photovoltaic industry, some deserts and plains with better conditions have been basically developed. As the available land resources are decreasing, the current photovoltaic power generation development areas are more likely to be located in scattered fish ponds, steep mountains and broken hills. Traditional rigid photovoltaic brackets are often difficult to adapt to these complex terrains, and multi-industry complementary projects such as fishery-photovoltaic complementation and livestock-photovoltaic complementation require sufficient space under the photovoltaic panels for agricultural breeding operations. Therefore, it is necessary to make a breakthrough in the form of traditional rigid photovoltaic brackets and find a photovoltaic bracket structure with strong terrain adaptability and high utilization rate.

[0003] The emerging flexible photovoltaic support system has largely solved this problem. The flexible photovoltaic support supports the photovoltaic panel through two flexible suspension cables. The photovoltaic panel and the suspension cable are connected by buckles, and the cable (steel strand) is pre-tensioned to give it sufficient rigidity and support. Flexible photovoltaic supports can achieve large-span overhead. On the one hand, the required support structure is reduced, saving the amount of steel and concrete consumed by the support structure; on the other hand, it greatly improves the space utilization rate of the ground, ensuring that there is enough space under the photovoltaic panel for agricultural and animal husbandry activities. In addition, the use of flexible cables makes it no longer necessary for the photovoltaic panel layout to be on the same horizontal plane for each span, thereby improving the adaptability to complex terrain.

[0004] However, existing flexible photovoltaic support structures often have certain problems, such as insufficient wind resistance and inability to ensure the out-of-plane stability of the truss structure.

[0005] Therefore, there is an urgent need for a photovoltaic bracket to solve the above problems. Utility Model Content

[0061] Furthermore, as Figures 4-7 ​As shown, the top end of the first fixing rod 3131 is fixedly connected to the top end of the second fixing rod 3132, the bottom end of the first fixing rod 3131 is fixedly connected to the bottom end of the third fixing rod 3133, the bottom end of the second fixing rod 3132 is fixedly connected to the bottom end of the fourth fixing rod 3134, and the top end of the third fixing rod 3133 is fixedly connected to the top end of the fourth fixing rod 3134, making the fixing bracket 313 an integral whole and improving the connection and fixing effect of the fixing bracket 313 on the longitudinal support rod 311 and the transverse support rod 312.

[0062] Optionally, as Figures 1-7 shown, a plurality of longitudinal pulling units 1 are provided, and the plurality of longitudinal pulling units 1 are arranged at intervals along the transverse direction of the flexible photovoltaic bracket. The support units 31 of the truss 3 are arranged in one-to-one correspondence with the longitudinal pulling units 1, so as to be able to increase the installation quantity of the photovoltaic panels.

The second anchor piles are fixed to the ground on the side of the side pile cross beam 16 away from the second main cable 12, and the other end of each second side anchor cable 18 is connected to the top of the corresponding second anchor pile. Through the anchoring of the first side anchor cables 17 and the second side anchor cables 18, the loads received by the first main cable 11 and the second main cable 12 are borne.

Under a relatively high wind load, the maximum deflection can still be less than L / 50, where L is the span of the flexible photovoltaic support in the east-west direction, that is, the distance between two adjacent middle support units 4, and is also the distance between the side pile cross beam 16 and the adjacent middle support unit 4. In this embodiment, the east-west direction is the longitudinal direction of the flexible photovoltaic support, and is also the extending direction of the first main cable 11, the second main cable 12 and the wind-resistant cable 13. Compared with the existing planar truss design scheme, the flexible photovoltaic support provided in this embodiment can better resist wind loads in multiple directions, prevent the out-of-plane instability problem existing in the planar truss scheme, and the stable spatial support brings good anti-overturning performance to the overall structure, avoiding instability and reducing the risk of hidden cracks in the components due to overturning.

[0071] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
