Mesh-supported floating photovoltaic power station

Abstract

A mesh-supported floating photovoltaic power station is disclosed, a main network system comprises a main cable which is arranged across the water surface and is laterally and longitudinally staggered, each main cable is anchored to the shore at both ends by steel spiral piles, power generation units are arranged in each cell of the main network system, and each power generation unit comprises floating bodies arranged in rows and in columns, the floating bodies in each row are connected by transverse secondary cables, the floating bodies in each row are connected by longitudinal secondary cables, the two ends of each transverse secondary cable and the longitudinal secondary cables are fixedly connected with the main cables, and photovoltaic modules are fixed on each floating body. The power station adopts a ''big mesh sleeving small mesh'' structural system as a main support structure, bolts or pins between floating bodies are canceled, canceling underwater pile anchors and anchoring,and anchoring the whole system to steel spiral piles on the water bank can effectively prevent the floating bodies and photovoltaic modules from being stacked and squeezed, which is suitable for deepwater area environments such as reservoirs, large fish ponds and coal mining subsidence areas.

Description

technical field [0001] The present invention relates to a floating photovoltaic support system, and more specifically relates to a grid support floating photovoltaic power station. Background technique [0002] In deep water environments such as reservoirs, large fish ponds, and ponds in coal mining subsidence areas, the traditional prefabricated pile foundation support scheme is difficult to implement, and floating photovoltaic support systems are preferred. At present, the common floating photovoltaic power plants at home and abroad mainly include two forms: photovoltaic support + floating body type and floating body integrated type. The photovoltaic support + floating body type adopts the form of a floating body supporting a steel support, and the steel support supports a photovoltaic module. The upper part is heavy, and the rigidity of the system is also large, which is prone to connection damage. The integrated floating body adopts the integrated structure of floating ...

AI Technical Summary

Problems solved by technology

However, in large-area and deep water MW-level projects, the bolts or pins between the floating body and the floating body are prone to stress concentration under the combined action of wind, wave and current, causing extrusion or tensile damage, which in turn causes the floating body and photovoltaic modules to be stacked and squeezed. Ultimately lead to the destruction and failure of the power station system

Moreover, in the case of deep water depth and unstable water bottom surface, it is difficult to implement pile anchoring and anchoring.
