At this time, seawater in the sea enters the first chamber from the first check valve 130 and enters the first container 151 through the second check valve 140. At the same time, seawater from the sea also enters the second chamber through the third one-way valve 170 and enters the first container 151 through the fourth one-way valve 180. The pure water in the pressure-applied seawater permeates into the second container 152 through the first filter unit 161 and permeates again through the second filter unit 162 to supply water to the floating island located above the second filter unit 162. Therefore, under the condition of not providing extra power, the seawater can be continuously and automatically desalinated by utilizing natural wind power or sea waves, the fresh water required by the growth of the crops on the floating island is provided, the seawater desalination cost is reduced, and the problem that the seawater desalination is difficult to apply to crop planting is solved. Meanwhile, due to the arrangement of the third one-way valve 170 and the fourth one-way valve 180, the water supply amount to the floating island can be further increased, and the efficiency of seawater desalination is improved.
