According to an aspect of the present invention, there is provided a dissolved air extraction device using a centrifugal force including an inlet where an underwater fluid is supplied; an inner chamber that is formed to communicate with the inlet and extend in a longitudinal direction, in which the supplied fluid flows backward while forming a swirling stream to generate a bubble column in a swirling center portion; an outlet that communicates with the back of the inner chamber so that the flowing fluid is discharged; and an air outlet that provides a flow passage so that the air in the bubble column is extracted out of the inner chamber. According to another aspect of the present invention, there is provided an underwater breathing apparatus including a dissolved air extraction device; a fluid supply line that suctions an external fluid and supplies the fluid to the dissolved air extraction device; a fluid discharge line that discharges the fluid which is discharged from the dissolved air extraction device outward; an air sampling line that is connected to an air outlet of the dissolved air extraction device so that the extracted air flows; and a storage tank that is connected to the air sampling line so that the extracted air is stored, and provides a user with air required for breathing through an air supply line.
Abstract:
The present invention relates to a pump having a two-way check valve function for an artificial gill, and more specifically, to a pump having a two-way check valve function for an artificial gill which guides fluids to flow in one direction using the driving principle of a check valve; enables a user to easily get air from the artificial gill system by using both hands, in order to prevent the unstable operation of the artificial gill system as well as fatigue and paralysis of the user caused by the user continuously using only one hand for operating the artificial gill system underwater; and simplifies the structure and enables a nozzle/flapper type or shuttle type two-way operation to maintain high airtightness.

Abstract:
PURPOSE: A marine load actuating device, a marine structure proof-test device thereof, and a proof-test method thereof are provided to artificially generate various types of external loads which are closed to real loads generated by wind, waves, and tides on a large tested marine structure on the sea by using the propulsion of a power vessel and the operational power of a linear actuator which is mounted on the power vessel. CONSTITUTION: A marine load actuating device (1) comprises a power vessel (10) and a linear actuator (12). The power vessel floats on the sea, and moves by using self-power. The linear actuator is flexibly connected to a support structure (11) which is installed on the power vessel. External loads are applied to a tested marine structure (5) by using a horizontal moving propulsion of the power vessel on the sea, the operational power which is generated by the linear actuator or the own weight of the power vessel, and the surface tension of sea level.
