Test observation subunit of circulating cavitation channel

摘要

The present invention relates to an apparatus for replacing a test observing part of a circulating cavitation channel for a ship test, and a device for replacing a test observing part of a circulating cavitation channel having two test observing parts, The bottom portion 140 of the lower portion of the test observation portion 20 including the contraction portion 40 and the diffusion portion 50 at a position capable of supporting the weight of the test observing portions 20 including the diffusion portion 50, A plurality of rails 100 extending parallel to both sides of the cavitation channel 10 in a direction perpendicular to the longitudinal direction of the test bench 20 are provided on a support 110 provided at a predetermined height from the bottom 140 ); And a plurality of test units 20 connected to the lower surface of the test observation unit 20 including the respective contraction units 40 and the diffusion unit 50 at positions corresponding to the rails 100, A bogie 120 with a wheel 122; And a drive means (130) for moving the carriage (120) along the rail (100).
