Abstract

The invention discloses a fresh water supply station making use of ocean current energy, and belongs to the technical field of ocean renewable energy technology. The fresh water supply station, in accordance with ocean current and tidal current distribution, is formed as a corresponding ocean area distributed fresh water supply station so as to supply fresh water to ocean ships and islands. The fresh water supply station, in accordance with local ocean current energy situations, is provided with multiple sets of ocean current energy seawater desalting devices; seawater, which is pressurized by virtue of the ocean current energy, is desalted and the generated fresh water is kept in an upper space of a caisson and is conveyed to the ships, and rest energy is comprehensively utilized so as to offer required electric energy and other power to a system; and a lower space of the caisson is filled with the seawater, the caisson integrally serves as a basic platform of the fresh water supply station, and the ocean current energy seawater desalting device is arranged on the basic platform.

Description

technical field [0001] The invention relates to a fresh water supply station using ocean current energy, which belongs to the field of marine renewable energy development. Background technique [0002] Energy and environmental issues are major issues related to the sustainable development of mankind. At present, the storage of non-renewable energy such as coal, oil and natural gas is decreasing day by day, and the development of clean renewable energy has become the consensus of all countries in the world. At present, the development and utilization of clean energy are mainly concentrated on solar energy and wind energy with large reserves, while ocean energy resources are abundant in the world, among which tidal current energy has strong regularity, stable tidal current direction, and typical reciprocating nature. In addition, the ocean current energy in the deep sea has the characteristics of long action time, stable direction and constant speed, and the development and ap...
