Integrated power generation device capable of comprehensively using renewable energy sources at sea

Abstract

The invention discloses a floating-type integrated power generation device capable of comprehensively using renewable energy sources at sea, and relates to the fields of methods and devices for generating power through solar chimney hot air flow, wind power, marine current energy, solar photovoltaic energy and fuel cells. The device comprises a marine current energy power generation unit, a standcolumn body, a platform layer, a heat collecting shed, a solar chimney and a vertical axial fan. The device can achieve comprehensive use of multiple renewable energy sources and has the following advantages that firstly, the stand column body and the marine current energy power generation unit are combined, therefore, stable utilization of marine current energy is facilitated, and the cost of constructing marine current energy power generation facilities is reduced; secondly, solar chimney power generation and wind power generation are combined, the two modes complement each other, and therefore the cost of constructing wind power tower frames is reduced; and thirdly, solar chimney power generation and fuel cell waste heat power generation are combined, therefore, resources are saved, theefficiency of fuel cells is improved, the air heating speed is improved, and the area of the solar chimney power generation heat collecting shed is decreased.
