The action of the multi-function floating body having the pile-type anti-flow unit according to the present invention configured as described above will be described as follows.

The multifunctional floating body 10 according to the present invention is a structure installed on the coast or the ocean, that is, referring to the drawings, the multifunctional floating body 10 according to the present invention is an offshore structure, that is, an offshore plant, a floating pension, and a floating pier. ), floating bridges, floating docks, floating breakwaters, yacht moorings, or marine parks.

The multifunctional floating body 10 that provides buoyancy to such an offshore structure is continuously affected by waves and sailing waves and wind according to the operation of the ship while floating in the sea. The waves and anti-frequency waves continuously collide with the side surface of the floating body, so that the lateral flow of the floating body portion is relatively large.

However, the multifunctional floating body 10 having a pile-type anti-flow unit according to the present invention is supported by the support 60 on the floating body 20 and the anti-flow unit 50 protrudes from the lower surface of the floating body 20 Since the pile-type flow prevention member 51 is provided, it is possible to suppress the occurrence of lateral flow by increasing the resistance during flow in the lateral direction.

That is, as shown in FIG. 9, since the flow prevention member 51 protruding from the lower surface of the floating body portion 20 is formed in a polygonal or plate-shaped cross section, the floating body portion 20 ) From the lower surface to the end side of the flow prevention member 51, the resistance opposing the flow in the transverse direction of the floating body portion increases. Accordingly, the lateral flow of the floating body part 20 can be minimized.

In particular, since bilge keel parts 81 are formed on both sides in the longitudinal direction on the lower surface of the floating body part 20 as shown in FIG. ) and can be reduced by doubling. When the lateral flow of the floating body part 20 occurs, the bilge keel part 81 generates a flow force to flow the seawater toward the sofa space, and this flow force collides with the reaction force by the seawater inside the sofa space and is offset . The ability to prevent lateral flow of the buoyancy body is improved.

In addition, the bilge keel part 81 formed on the lower surface of the floating body part 20 is rotated in the left and right directions at a position relatively spaced from the center of gravity when lateral flow of the floating body part 20 occurs, preventing pile-type flow Since the member 51 is formed in a plate shape, rotational resistance is relatively increased during left and right rotation, thereby preventing lateral movement of the floating body.

On the other hand, the anti-frequency waves or waves are extinguished by the inflow of seawater into the sofa passage part 82 formed in the bilge keel part 81, so that the impact energy of the waves or anti-frequency waves can be prevented from being transferred to the side of the floating body part. When the flow force of the wave flowing into the lower surface of the floating body part 20 is introduced into the sofa space formed between the bilge keel parts 81, vortexes are generated, so that the wave force is offset and sofaed.

As described above, the multifunctional floating body having the pile-type anti-flow unit according to the present invention can prevent the floating body from fluctuating due to waves, anti-floating waves, etc. When the main body is rotated, the rotational resistance rapidly increases as it goes from the lower surface of the floating body to the end side of the flow prevention member, so that the lateral flow of the floating body can be prevented.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom.

Therefore, the true protection scope of the present invention should be defined only by the appended claims.

The multifunctional floating body having a pile-type flow prevention unit according to the present invention can be widely applied to buoyancy bodies for floating various offshore structures, buoyancy bodies of solar power generation devices installed on the sea, and floating wind power generation buoyancy bodies.
