Underwater vortex induction equipment according to the present invention, comprises: a vortex forming means in which a plurality of vortex forming drums having an internal space with an open top surface are combined and distributed on the sea floor; a flow connecting means which connects each vortex forming drum and simultaneously allows each vortex forming drum to move individually within a certain range by means of the influence of the sea current; and a fixing means which allows the position of the vortex forming means to be fixed relative to the sea floor. The flow connecting means comprises a binding wire which continuously passes through the plurality of vortex forming drums. The fixing means comprises an anchor mechanism which includes a post portion to which the front end of a wire is fastened, and which includes a conical portion which is formed at the bottom of the post portion and is embedded in the sea floor, wherein the outer surface of the conical portion of the anchor mechanism has a hook piece portion of which the top protrudes from the top of the conical portion. According to the present invention, the energy caused by the flow of sea water is absorbed by means of an upwelling vortex formed in the vortex forming means, thereby reducing the damage of coastal erosion and sand loss due to sea waves, etc.
