Streamline noise measuring device for ultra-high-speed circulating water tank

The invention relates to a streamline noise measuring device for an ultra-high-speed circulating water tank, and belongs to the technical field of underwater sound detection devices. Comprising a water-drop-shaped flow guide cover, an airfoil-shaped flow guide neck body and an airfoil-shaped flow guide base which are connected in sequence, a hydrophone in flexible connection is arranged in the flow guide cover; the flow guide neck body is of a forward-swept sectional type telescopic structure. The streamline design is adopted in the appearance, flexible connection is adopted in the interior, water flow separation is restrained to the maximum extent, and interference caused by water vibration is reduced. And the self height is adjusted according to the noise position and the directivity of the hydrophone through the sweepforward segmentation design, so that the testing capability of the hydrophone can be well exerted. The device is simple in installation mode, can be used for noise measurement in various occas
