FLOATING TYPE AQUATIC SUPPORTAPPARATUS

Nº publicación 02/03/2022EP3960616A1Solicitantes KIM SU HWAN [KR] Resumen The present invention relates to a floating-type on-water

support apparatus, and more specifically, to a floating-typeon-water support apparatus allowing an offshore structure to beprevented from rotating in place. The floating-type on-watersupport apparatus incudes a ball, a floating unit including afloating part which floats on water and supports the ball so thatthe ball is rotatable, and a support rod of which one end isexposed above the water so that a structure is installablethereon and the other end is heavier than the one end so thatthe support rod stands vertically in the water and which iscoupled to the ball. In this case, a guide groove is formed alonga circumferential surface, which passes through the supportrod, of the ball. In addition, the floating unit further includes arestriction protrusion fitted into the guide groove to restrict theball from being rotated about an axis of the support rod and afixing member by which the restriction protrusion is installed onthe floating part. According to the present invention, since therestriction protrusion is fitted into the guide groove of the ball,the support rod coupled to the ball may be prevented frombeing rotated about a central axis thereof. Accordingly, when awind power generator is installed on the support rod, rotation ofa shaft of the wind power generator due to wind may beprevented.
