Claim Text:
1. A water circulating device installed in a park or a lake, comprising: an expandable corrugated tube unit having an expandable corrugated tube body that is provided so as to be able to adjust a length thereof in a vertical direction of a water area, has at least one inlet into which water located at a lower stratum of the water area flows, and is formed in a pipe shape, and a water disperser that is provided at an upper portion of the expandable corrugated tube body and disperses the water supplied from the expandable corrugated tube body to an upper stratum of an neighboring water area corresponding to an upper region of the expandable corrugated tube body; a unit frame supporting the expandable corrugated tube unit; a plurality of barge units that are radially connected outside the unit frame around the expandable corrugated tube body and provide buoyancy to the expandable corrugated tube unit and the unit frame; an impeller that is rotatably disposed at the expandable corrugated tube unit and disperses the water in the expandable corrugated tube unit to outside of the expandable corrugated tube unit; and a torque provider providing torque to the impeller, wherein the impeller includes a shaft having a deicer on at least one region and dispersion blades that are connected to the shaft and disperse the water in a radial outward direction, and each of the barge units includes a floating tank that has a tub structure and provides a substantial buoyancy, a barge unit support that is connected to the unit frame, and a free rotor that is provided on a region where the floating tank and the barge unit support are connected and freely rotates the floating tank relative to the barge unit support, wherein the floating tank is manufactured in a cylindrical or conical structure, and the barge unit support includes a transverse bracket connected to the unit frame in a transverse direction and a tank connecting shaft connected to the transverse bracket in a longitudinal direction, wherein the free rotor includes a disk provided at an upper end of the tank connecting shaft and a rotary housing that is connected to the floating tank at a lower end of the floating tank so as to prevent separation of the disk and is rotatable relative to the disk.
