DRAINAGE FOR AQUACULTURE TANK

摘要

A dual drainage apparatus for an aquaculture tank according to the present invention comprises: a water level adjusting pipe with a predetermined length; and a drainage pipe spaced apart from the water level adjusting pipe at a predetermined interval at a lower end thereof, and covering the outside of the water level adjusting pipe while keeping a predetermined space therefrom. The water level adjusting pipe and the drainage pipe are combined with each other in the drainage apparatus in order to continuously drain a predetermined amount of breeding water in the aquaculture tank where the internal bottom of the drainage pipe is sealed and a through hole for adjusting breeding water is formed in a part of a body of the drainage pipe. The drainage apparatus is formed with one drainage pipe even in an aquaculture tank where a material of the bottom of the aquaculture tank is thin so that a dual pipe structure is impossible, thereby enabling the water lever adjustment of breeding water.
