Large-span flexible cable supporting photovoltaic system

Abstract

The invention discloses a large-span flexible cable supporting photovoltaic system, which comprises photovoltaic modules, inhaul cables, stabilizing rods, cross beams, stand columns, oblique pull rods, bearing platforms, prestressed tubular piles, ground beams and a damping device. The large-span flexible cable supporting photovoltaic system is characterized by fully utilizing idle solar energy resources above places such as fish ponds, farmland or sewage treatment plants, setting up a solar photovoltaic assembly thereon, having the feature of ''one place for dual purposes'', adopting the inhaul cables as supporting structures of the solar photovoltaic assembly, achieving the purpose that the photovoltaic industry and other activities developed thereunder such as fishery, agriculture or sewage treatment operation do not interfere with one another, effectively improving the rigidness of the entire system through forming a criss-crossed supporting network by means of the inhaul cables and the stabilizing rods, being capable of dissipating the vibration energy of the inhaul cables by installing the damping device at a midspan position of the inhaul cables preferentially, and ensuring the safety of the photovoltaic assembly.

Description

technical field [0001] The invention belongs to the application field of photovoltaic systems, and in particular relates to a photovoltaic system supported by a large-span flexible cable. Background technique [0002] Conventional solar photovoltaic power plants are usually limited by land. For the eastern region where land is increasingly scarce, it is impractical to directly occupy land to build conventional large-scale ground power plants. Therefore, in order to effectively develop and utilize solar energy resources, "complementary" photovoltaic power stations such as fishing-solar complementarity and agriculture-solar complementarity, or other photovoltaic power stations built using idle solar energy, such as sewage treatment plant photovoltaic power stations, have emerged because they do not occupy additional Land resources are getting more and more attention from the industry. [0003] Traditional photovoltaic power plants such as fishing-solar hybrid and agricultural...

Problems solved by technology

However, since the cable structure is a kind of flexible structure, especially for long-span cable structures, the mid-span displacement under the action of wind load is often very large, if no effective measures to increase stiffness and reduce vibration and energy During the operation of the power station, the photovoltaic modules installed on it are prone to problems such as cracks, overturning and damage
