An Immersed Marine Acoustic Platform

Abstract

The invention relates to an immersion type acoustic platform for a ship. The acoustic platform comprises a case body, a top cover, a sound transmission plate, an acoustic transducer, a sound absorption rubber plate, a water feeding tube and an air exhaust tube. A mounting base is fixed on the lower portion of the side walls of the case body in a coverage mode and fixed with the outer side walls of the case body through bolts with sealing rings, and the mounting base is fixed on a ship bottom plate. Steps are arranged at the outer edges of the lower bottom side of the sound transmission plate, compression rings are mounted at the positions of the steps on the sound transmission plate and are fixed with lower flanges in the case body through the compression bolts with seals in a threaded meshed mode, and the sound transmission plate is closely attached to the lower flanges. According to the immersion type acoustic platform, a water tank is welded at the ship bottom through the water tank base, so that an original static structure can be kept for the water tank, the edges of the sound transmission plate are designed into step structures, and the compression rings are fixed on the lower flanges of the water tank bottom through the bolts, so that uneven stress of the sound transmission plate is prevented.

Description

technical field [0001] The invention belongs to the field of ships, and relates to an acoustic transducer platform, in particular to an immersed marine acoustic platform. Background technique [0002] Acoustic platform is a kind of bottom installation method of acoustic equipment, and it is a project to centrally install acoustic transducer equipment in a specific cabin. Incorporating the installation of multiple acoustic transducer (array) water tanks into the design and construction of this section of the hull as a whole will not only help to avoid the phenomenon of mutual occupation of positions, matching components, and overlapping of pipelines when they are installed independently occurrence, saving installation space, and reducing acoustic interference between acoustic transducers, optimizing the working efficiency of each device, and making efficient use of resources and materials. Provides a reliable guarantee. [0003] Currently, the acoustic platform consists of ...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. The water tank body is directly welded on the bottom plate of the ship’s bottom, which is difficult to control when releasing the stress, which may easily cause deformation of the bottom plane of the water tank and deformation of the sealing groove of the bottom flange, thus affecting the sealing performance of the bottom sound-permeable plate; 2. The edge of the sound-transmitting plate is punched and fixed on the bottom flange of the water tank with bolts. The force on the bolts is not easy to ensure uniformity, and the bolt holes of the sound-transmitting plate and the inner flange cannot be completely aligned. When the force is applied laterally, it is difficult to It is easy to cause cracks at the perforated part of the sound-transmitting board; 3. The echo noise in the water tank is relatively large; 4. The side of the sound-transmitting board facing the sea water is easy to attach and grow marine organisms
