ICE TANK HAVING DENSITY CONTROL FUNCTION OF MODEL ICE BY CIRCULATING BUBBLE INJECTION UNIT INSTALLED ON UNDERWATER CARRIAGE

摘要

The present invention relates to a water tank to test an environment of a special region when a vessel or a special purpose vessel like an icebreaker is constructed. According to the present invention, the water tank comprises: a water tank unit filled with tank water; a bubble injection unit to inject bubbles while being front/rear reciprocated in a longitudinal direction of the water tank unit under the water of the water tank unit; a driving unit to reciprocate the bubble injection unit in the water tank unit; a bubble supply unit connected to the bubble injection unit to supply the bubbles to the bubble injection unit; and a bubble discharge tank unit connected to the bubble injection unit to discharge the bubbles injected into the bubble injection unit. Thus, since the bubble injection unit, the bubble supply unit and the driving unit are installed to form the bubbles with a uniform density all over the ice tank, a density of a model ice approaches a density of ice frozen in a real sea area, so a model ice with the uniform density is frozen. Through effective arrangement and moving of bubble injection tubes, an effect of preventing the bubbles from being intensively generated in a predetermined part of the ice tank, and of dispersing and generating the bubbles with the uniform density all over the tank water is provided.;COPYRIGHT KIPO 2016
