NOVELTY - The equipment (100) has several collision boards (170) and ratchet structures (180) with respective pawl portion that hooks one of teeth, when board cases (174) are collided with a sea wave in a direction such that rotating shafts (132) are rotated with respective ratchet portions, and transmission shaft (160) is rotated by gear wheels (136,162), so that a generator (150) generates electrical power. Each pawl portions slides a portion of teeth, when board cases are collided with another sea wave in reverse direction, so that rotating shafts do not rotated with ratchet portions.    USE - Sea wave power generation equipment floated on sea surface.    ADVANTAGE - Since the rotating shafts are rotated with respective ratchet portions, and transmission shaft is rotated by gear wheels when board cases are collided with the sea wave in a direction, so that the generator generates electrical power efficiently. The board cases and the ratchet structures can ensure the transmission shaft only rotates in a single direction i.e. the power generation direction of the generator, when the board cases are collided with sea wave in a direction. The unavoidable disturbances are formed on the sea surface except the direction of the sea wave. The board cases of collision boards can return to under the sea surface by the ratchet structures due to the gravity or a disturbance reverse to the direction of the sea wave, such that the board cases can wait for the next collision of the sea wave. The structure of the sea wave power generation equipment is simplified and the sea wave power generation equipment is assembled easily, so that the material costs can be reduced. Since the sea wave power generation equipment floats on the sea surface, managers do not need to dive into water to assemble or repair the sea wave power generation equipments, and hence the labor cost can be reduced.
