Document Type and Number:
WIPO Patent Application WO/2015/152601
Kind Code:
A1
Abstract:
The present invention relates to an air injection apparatus that protrudes toward the seawater from the bottom plate of a vessel. The objective of the present invention is to achieve easy installation and assembly/disassembly of the air injection apparatus on the bottom surface of a vessel, to enhance water tightness for an air path, to enhance bubble generation efficiency by air injection into the seawater, and to efficiently reduce frictional resistance of the vessel by forming a bubble layer along the bottom surface of the vessel. The air injection apparatus, according to the present invention, comprises: an air injection module that is installed to be located on the bottom surface of the bow of a vessel and has a plurality of air paths and air injection holes formed therein, the plurality of air injection holes being formed to communicate with the air paths and the outside thereof; and an air supply structure that is installed to be connected to the air injection module while passing through the bottom of the vessel and supplies air into the air paths of the air injection module, wherein the air injection module includes: a base plate that is installed on the bottom surface of the vessel through welding and through which the air supply structure is installed to pass; an air injection plate that is coupled to a positioning part of the base plate and has an air path and a plurality of air injection holes formed therein, wherein the air path communicates with the air supply structure, and the plurality of air injection holes communicate with the air path; and a connecting plate that is installed to be located between the base plate and the air injection plate and has a sealing function.
