A kind of immersion acoustics platform peculiar to vessel, comprise casing, top cover, entrant sound plate, acoustic transducer, sound absorbent rubber plate, coolant inlet pipe, freeing pipe, casing is upper, under shed structure, bolt coaxial packaging top cover is passed through in upper shed at casing, under shed encapsulation entrant sound plate at casing, the upper flange that in casing above entrant sound plate, axis position is fixedly mounted with by box inside wall, lower flange is fixedly mounted with acoustic transducer, madial wall at casing, top cover inwall, the inwall of upper flange and lower flange is all fixedly mounted with sound absorbent rubber plate, on the top cover of casing, freeing pipe is installed, at the sidewall of casing, coolant inlet pipe is installed with being communicated with in casing, it is characterized in that:
The coated mounting base that is fixed with in the bottom of casing lateral wall, this mounting base is by bolt and adopt seal ring and casing lateral wall is fixedly mounted with, and this mounting base is packed on hull base plate;
The lower bottom side outer rim of described entrant sound plate is shaped with step, on the entrant sound plate of this stepped portions, a pressure ring is installed, and this pressure ring adopts sealing and the lower flange in casing to be solidly installed by push bolt, and makes entrant sound plate be close to lower flange.
And, after being first sand-blast finish, the inwall of madial wall, top cover inwall, upper flange and the lower flange of casing sticks again sound absorbent rubber plate.
And, at entrant sound plate, towards the lower bottom side of seawater, before lower water, first apply anti-marine life paint.
And described casing is circular or square.
Advantage of the present utility model and beneficial effect are:
