<P>PROBLEM TO BE SOLVED: To provide a deep ocean water nutrient salt pumping apparatus promoting growth of marine algae by pumping deep ocean water, and contributing to sea alga methanized energy and culture of fish and shellfish fed with sea algae. <P>SOLUTION: This ups and downs-type wind force deep ocean water nutrient salt pumping apparatus includes a windmill 1 which is resistant to waves-wind pressure and subsidence under the sea surface, a dual structure outer cylinder 5 which is resistant to shock of water particles of waves, and a pumping tube 5a which is protected from shock from water particles by the outer cylinder 5. The pumping apparatus drives an axial-flow pump 4 by rotation of the windmill 1, pumps deep ocean nutrient salt water, and scatters deep ocean nutrient salt water over a sea alga vegetation net with a spray hose 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
