The invention relates to an underwater sound test catamaran wave dissipation device which comprises a wave dissipation plate and a hydraulic mechanism, one end of the wave dissipation plate is rotatably arranged on a ship shell, the wave dissipation plate is of a curved-plate-shaped structure, the curved surface is arranged upwards, a grid structure is arranged on the upper surface of the wave dissipation plate, and a drainage groove is formed in the lower surface of the wave dissipation plate; the hydraulic mechanism is arranged on the ship shell and located below the wave absorbing plate. Wherein the hydraulic mechanism ascends and descends to drive the wave absorbing plate to ascend and descend, after the hydraulic mechanism shrinks, the other end of the wave absorbing plate can be immersed into water and is used for reducing underwater radiation noise generated when sea waves flap the ship shell, the grating structure of the wave absorbing plate is a strip-shaped grating water permeable hole, and the trend of the drainage groove and the strip-shaped grating water permeable hole form an angle of 45 degrees. The grating type wave dissipation structure is adopted to be matched with the drainage grooves, and underwater radiation noise generated when sea waves flap the ship shell can be reduced; and vibration isolation installation is adopted, transmission of excited vibration of the wave absorbing plate to the ship body is reduced, and underwater radiation noise is further reduced.
本发明涉及一种水声测试双体船消浪装置,包括消波板和液压机构,消波板一端转动设置在船舶壳体上,消波板为曲面板状结构,且曲面向上设置,消波板的上表面设置有栅格结构,消波板的下表面设置有疏水槽;液压机构设置在船舶壳体上,且处于消波板下方;其中,通过液压机构的升降带动消波板的升降,液压机构收缩后消波板的另一端能够浸入水中,用于降低海浪拍打船舶壳体的水下辐射噪声,所述消波板的格栅结构为条形格栅透水孔,所述疏水槽的走向与条形格栅透水孔呈45度。本发明采用格栅式消浪结构配合疏水槽,能够降低海浪拍打船舶壳体的水下辐射噪声;采用隔振安装,减小消波板受激振动传递到船体,进一步降低水下辐射噪声。
