Half-immersion type marine acoustic platform

Abstract

The invention relates to a half-immersion type marine acoustic platform. The half-immersion type marine acoustic platform comprises a box body, a sound transmission plate, an acoustic transducer, a sound-absorbing rubber plate, a water inlet pipe and a water outlet pipe. A mounting base is fixedly arranged on and coats the outer side wall of the box body and is welded on a bottom plate of a ship body; a step is formed on the outer edge of the lower bottom side edge of the sound transmission plate, the portion of the sound transmission plate at the step position is provided a press ring, the press ring and the threads of a lower flange inside the box body are engaged and fixedly arranged together in a sealed mode to enable the sound transmission plate to be tightly adhered to the lower flange. The half-immersion type marine acoustic platform guarantees that a water tank can maintain an original static structure by welding the water tank at the bottom of a ship through a water tank base. According to the half-immersion type marine acoustic platform, the edge of the sound transmission plate is designed into a step structure, the press ring is fixed on the lower flange at the bottom of the water tank through bolts and meanwhile tightly presses the sound transmission plate to enable the sound transmission plate to be tightly adhered to the lower flange, an O-shaped seal ring is used for guaranteeing watertightness, and the installed press ring also has a stress transmission function to avoid uneven stress of the sound transmission plate.

Description

technical field [0001] The invention belongs to the field of ships, and relates to an acoustic transducer platform, in particular to a semi-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...

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
