Artificial-whirlpool generator

A whirlpool generator to generate an artificial-whirlpool to a waterbody, comprising:

• a whirlpool generating member, the whirlpool generating member including a whirlpool generating chamber extending in a vertical center axis and having a cylindrical inner chamber surface, the whirlpool generating chamber having a partially closed or completely closed upper end and an open bottom end, and a connection conduit having a water inlet formed through a side surface of the whirlpool generating chamber and directed transversely in a tangential direction of the whirlpool generating chamber;
• and
• a water feeder coupled to the water inlet of the whirlpool generating chamber to provide a pressurized water stream through the tangentially directed water inlet of the whirlpool generating chamber, and thus generating a swirling water flow rotating about the vertical center axis of the whirlpool generating chamber around the cylindrical inner chamber surface of the whirlpool generating chamber, and the swirling water flow forming a whirlpool directing downward through the open bottom end of the whirlpool generating chamber and descending toward a bottom side of a waterbody, and thus, enhancing a water quality and a level of dissolved oxygen in the water body,
• wherein a suction mouth of the connection conduit is located inside of the water body, and the water feeder is located at an intermediate position between the suction mouth and the whirlpool generating chamber,
• wherein both the partially closed or completely closed upper end and the open bottom end of the whirlpool generating chamber are submerged in the waterbody.
