3 to 5, the pile guide 200 for floating structures on the sea includes a guide frame 210, a coupling member 220, and a leaf spring 230.

First, the guide frame 210 is formed by connecting a plurality of plates 212, and includes a pile mooring space 205 inside. The guide frame 210 may form a rectangular guide frame 210 by connecting the four plates 212, and may be changed into various shapes by adjusting the number of plates 212.

The coupling member 220 is provided inside the guide frame 210, and two coupling members 220 form a pair. The pair of coupling members 220 are disposed to be spaced apart from each other by a predetermined interval.

The leaf spring 230 in which one or more leaf springs 230 are overlapped is disposed having both ends fastened with a pair of coupling members 220. For example, one end of the leaf spring 230 is fastened to the coupling member 220 disposed on one side, and the other end of the leaf spring 230 is fastened to the coupling member 220 disposed on the other side. The distance between the pair of coupling members 220 is arranged to be narrower than the line width of the leaf spring 230, and thus the elastic leaf spring 230 has an arcuate curved surface inside the guide frame 210.

The coupling member 220 may be formed in an insert form or a hinge structure, and may move fluidly within the coupling member 220 by the elasticity of the leaf spring 230.

A plurality of fixing members 240 are provided on the upper surface of the leaf spring 230, and two fixing members 240 form a pair. A pair of fixing members 240 are disposed to be spaced apart from each other by a predetermined interval.

The outer circumferential surface of the mooring pile 260 accommodated in the pile mooring space part 205 comes into contact with the guide roller 250 provided on the upper surface of the leaf spring 230. The guide roller 250 rotates along the mooring pile 260 when the floating structure ('160' in FIG. 1) moves up and down so that the floating structure can be moved up and down very easily. In addition, the guide roller 250 may have a concave portion adjacent to the mooring pile 260 as shown in FIG. 4, and may be formed in a form in which a plurality of guide rollers 250 are connected as shown in FIG. 5.

In this way, by installing a leaf spring with elasticity applied to the pile guide used for pile mooring of an offshore floating structure, it absorbs external shock through the leaf spring when weather changes and tidal tidal differences occur, reducing the rolling pitch and reducing the rolling pitch. Damage can be reduced. Accordingly, floating structures and piles on the sea can be protected.
