The invention relates to a floating-shifting type ocean technology school and national defense post, wherein a large-scale floating raft formed by a plurality of groups and layers of floating pipes A and side floating pipes Ab is anchored in an ocean; the pointed ends of the floating pipes are aimed at upwind and ocean waves; the front end of the raft aggregates the density of wind energy througha big trumpet taper cylinder B group, raises wind speed and guides the wind to respective generator rooms of A5 and A6 for power generation and to a sunshine layer of a top layer for photovoltaic generation, so as to provide energy for the electrification of a floating-shifting campus, aquatic product refrigeration, seawater desalination and the propagation of plants, vegetables, fruits and mushrooms in ecological forests. A huge net is stretched in a water area under large-span wind tubes of the B group, so as to form a big fish aquiculture-storage area, which is also a good place for enjoying beside-net shore 'sand beach' type scenery, traveling, lying fallow, sailing, canoeing and learning to drive dynamic yachts and dynamic paragliders, as well as a safe place for diving with oxygen cylinders. Ad is an ecological forest botanical garden, which is followed by a campus Ae for teaching, learning, research, aquatic products, technology, etc., so as to form an on-water city campus and national defense post. The safety of teachers, students, workers, medical treatment, literature and tourism is completely guarded by the police and the army. The floating-shifting type ocean technology school and national defense post is a center of army-civilian solidarity and mutual help, and is integrated with national defense enhancement.
