Description

Rotable Buoyant Structure to remove debris attached to a surface

The present invention relates to a buoyancy structure. Specifically, it relates to a rotary buoyancy structure capable of removing foreign substances attached to the surface.

Structures are being installed on the sea for various purposes, such as structures for aquaculture of fish and shellfish, and water power generation. In this case, a buoyancy structure such as a buoy is used to support the structure to be installed by buoyancy.

A part of the buoyancy structure is submerged in the sea, and marine organisms such as fish and shellfish are frequently attached to the submerged part as foreign substances.

When a lot of foreign substances are attached to the buoyancy structure, the buoyancy force that the buoyancy structure must support is affected. Therefore, the operation of removing foreign substances at a certain period is being performed.

However, since the prior art does not have a separate foreign material removal technology, a method of lifting the buoyancy structure to remove the foreign material and inputting it again is generally used. In this case, there is a problem that an additional operation of lifting the buoyancy structure is input, and the operation of removing the buoyancy structure while looking up from the bottom of the buoyancy structure to remove foreign substances attached to the bottom of the buoyancy structure is very inconvenient and the efficiency is lowered. is raised

In order to solve this problem, Korean Patent No. 10-1845984 discloses a technique for removing foreign substances when a buoy is replaced.

However, this prior art also removes foreign substances on the premise that the buoyancy structure is replaced, and removes foreign substances attached to the surface of the buoyancy structure without a replacement process, and in that the buoyancy structure cannot be used, the practical utility is not There was a very low problem.
