WATER TANK FOR INLAND SEA FARMING TO ENABLE NATURAL CIRCULATION OF SEAWATER

摘要

The present invention relates to a water tank for inland sea farming to enable natural circulation of seawater, and the water tank comprises: a certain volume of a fish tank (100) which is constructed through excavation in the ground; a water inlet passage (200) which comprises an overground passage (210) that is constructed along the ground while one end thereof is communicated with the sea (S) so that seawater may flow in, an underground passage (220) that is inclined to mutually communicate the lower end of the fish tank (100) and the overground passage (210), a first filter (f1) that is provided in the overground passage (210) or the underground passage (220) in order to filter foreign substances out of the seawater flowing from the sea (S), and a second filter (f2) that is provided at the communicated position between the fish tank (100) and the underground passage (220) and prevents marine life from escaping out of the fish tank (100); and a water outlet passage (300) which is constructed along the ground by communicating with the fish tank (100) so that the seawater of the fish tank (100) may be discharged, and includes a third filter (f3) that is provided to prevent the sea life from escaping when filtering foreign substances out of the seawater.
