Title:

CLOSED ECOLOGICAL SYSTEM EXPERIMENT APPARATUS HAVING PIPING STRUCTURE CAPABLE OF CONTROLLING FLOW RATE ACCORDING TO WATER DEPTH

Document Type and Number:

WIPO Patent Application WO/2016/129793

Kind Code:

A1

Abstract:

A closed ecological system experiment apparatus (1), according to the present invention, comprises: an ecological tank (30) provided with inlets (31) formed on one side wall of a plurality of levels at different heights and outlets (32) formed on the other side wall of the plurality of levels at different heights; a plurality of inflow pipes (40) installed to correspond to the inlets (31); a plurality of outflow pipes (50) installed to correspond to the outlets (32); flowrate control means (41, 51) installed on each of the inflow pipes (40) and the outflow pipes (50); a distribution tank (20) installed so as to supply water to the ecological tank (30) through the inflow pipes (40); a combining outflow pipe (80) installed to connect to the plurality of outflow pipes (50) so that water flowing out from each level of the ecological tank (30) through the outflow pipes (50) is combined and then discharged externally; a branch pipe (87) installed so as to branch out from the combining outflow pipe (80); a water container (85) arranged to collect water discharged through the branch pipe (87); a combined discharge opening/closing valve (82) installed on the combining outflow pipe (80) to be positioned behind the area from which the branch pipe (87) is branched; and a branch pipe opening/closing valve (81) installed on the branch pipe (87). According to the present invention, ecological research can be carried out in conditions close to real ecological conditions involving flowing water, such as rivers, streams, and oceans, by varying the flow rate depending on the depth of water, thus ecological environments underwater can be very accurately and reliably investigated and studied.
