Floating type offshore photovoltaic power station semi-submersible platform

Abstract

The invention discloses a floating type offshore photovoltaic power station semi-submersible platform. The system comprises a photovoltaic assembly array, a truss structure and a floating body foundation, the photovoltaic assembly array is used for converting solar energy into electric energy, electric power is connected to a power grid through a power transmission line, the photovoltaic assembly array is installed on the truss structure through a support, and the floating body foundation is fixed to the bottom of the truss structure, suspends in the sea and is connected with a mooring system. The water plane area and the wave load of the photovoltaic array floating body are greatly reduced, the structural safety of the floating body foundation is improved, the strength is high, the buoyancy is high, the stability is good, the steel consumption is small, and the photovoltaic array floating body foundation can resist a worse marine environment.

Description

technical field [0001] The invention belongs to the technical field of offshore photovoltaic power generation, and in particular relates to a semi-submersible platform of a floating offshore photovoltaic power station. Background technique [0002] At present, the proportion of new energy is getting higher and higher. Photovoltaic power stations have the advantages of zero pollution and zero emissions, and are one of the fastest-growing new energy sources in recent years. The existing water surface photovoltaics are deployed in inland lakes, rivers, reservoirs, fish ponds and other reservoirs, using fixed pile foundations or floating foundation. Since many inland waters are within the ecological red line designated by the state or surface water sources for drinking water, some waters have the functions of navigation and flood control, which limits the development of surface photovoltaics to a certain extent. [0003] The water area is vast and unrestricted, and it is close...

AI Technical Summary

Problems solved by technology

Compared with the inland environment, the wind, waves, currents and other environments are more severe in the marine environment, and there are also problems such as corrosion and marine organisms. The existing fixed water surface photovoltaics have a greater impact on the seabed topography, and the construction is complicated, so it is not suitable Applied to the marine environment, and floating photovoltaics on the sea is a more feasible solution

[0004] The high-density polyethylene floating tanks and floating tubes used in the existing surface floating photovoltaics are developed for inland waters and mainly bear wind loads. However, the wave loads in the marine environment are more important and corrosive, and the existing floating photovoltaic floating bodies cannot Meet the operating requirements of photovoltaic power plants, and are prone to equipment damage
