The device has a hydropower adjusting function and can adjust the ratio of the electricity for electricity transmission to the electricity for sea water desalination.

Description

technical field [0001] The invention belongs to the technical field of generating electricity by using tidal current energy, and in particular relates to an integrated device for generating electricity and seawater desalination by using tidal current energy. Background technique [0002] Ocean energy is a clean, sustainable and renewable energy that is rich in resources and has little impact on the environment. It is of great significance to alleviate the energy crisis and environmental pollution problems. At present, the exploitable marine energy includes tidal energy, wave energy, tidal current energy and so on. Due to its strong predictability, tidal current energy has greater advantages compared with wave energy in terms of stable power supply. At the same time, compared with the utilization of tidal energy, the utilization of tidal current energy does not need to change the natural environment to a large extent, so it has become a research hotspot. . my country's coas...
