NOVELTY - The device has a first bubble generator for setting a floodgate in a waterway. A U-shaped opened top portion is adhered with a front side of the floodgate for generating bubble. A vertical wing is installed along vertical direction. Another floodgate is arranged in an end of second bubble generator to generate the bubble when seawater reboil bubble is generated due to rotation of the vertical wing. The latter floodgate is arranged with a third bubble generator. A generator support facility is arranged into an oceanic pasture according to a large size waterway of the opened top portion.    USE - Perpendicular low speed rotation tidal energy generation device for use in a tide embankment.    ADVANTAGE - The device can generate the bubble by connecting an oceanic pasture endodermis canal within the tide embankment for enhancing and emitting dissolved oxygen, thus circulating fresh-water in an inner side of the oceanic pasture. The device can generate electricity through a seawater head generator positioned at a lower part of the tide embankment for generating the bubble in seawater falling power generation in a spinning phase of a rotary. The device is provided with a lamp arranged in a part, where seawater is dropped and irradiated so as to view a cleanness region, thus improving anion synergistic effect of seashore. The device can discharge the seawater such that a head is gradually restored to the clean sea. The device converts seawater pressure energies into electricity so as to enhance generated energy, improves economical efficiency, generates clean energy by a clean development mechanism and protects family resources due to perpendicular low speed rotation of the rotating blade at low speed and shortens construction period rather than conventional high speed rotating generator setting time and reduces repair-exchanging and installation fee. The device is covered with a deposition layer in a cardinal number river composition for scattering of marine algae and fishes in which content of the dissolved oxygen stabilizes within an oceanic pasture, thus improving large-scale artificial breeding efficiency.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a perpendicular low speed rotation tidal energy generation device.'(Drawing includes non-English language text)'
