Embodiment Construction

[0022] Specific embodiments of the present invention will be described below.

[0023] Such as Figure 1 to Figure 4 As shown, a modular underwater pressure-resistant sound insulation baffle is formed by pasting several modules to form a baffle structure. The module includes a hollow and sealed spherical shell 1, which is a stainless steel shell. The stainless steel shell is to ensure the pressure resistance of the air ball cavity. The hollow interior of the spherical shell 1 is an air balloon cavity, and the acoustic impedance of the air balloon cavity is smaller than that of water. The outer periphery of the spherical shell 1 is covered with silicon rubber 2, and the outer periphery of the silicon rubber 2 is covered with a shell 3. The shell 3 is a rubber cube shell, and the rubber cube shell is rectangular. A vulcanized rubber plate 4 is bonded to the outer periphery of the casing 3 . Such as figure 1 As shown, the above-mentioned silicone rubber 2 is composed of two c...

Abstract

The invention relates to a modular underwater pressure-resistant sound insulation baffle. The baffle structure is formed through pasting multiple modules, the modules include spherical shells which are hollow and sealed inside, outer peripheral surfaces of the spherical shells are coated with silicone rubber, an outer casing is coated on the outer periphery of the silicone rubber, and a vulcanizedrubber sheet is bonded to the outer periphery of the outer casing. The baffle structure is advantaged in that the structure is simple and is convenient to use, through optimizing the thickness of thestainless steel spherical shells as well as the rubber density, the overall equivalent density of the baffle structure is the same as the water, the weight of a carrier in an underwater use state isnot increased, the good middle and low frequency sound insulation effect is achieved, the modular structure facilitates batch processing and modular cutting, and the environment in which the scale changes can be effectively adapted.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to a modular underwater pressure-resistant and sound-insulating baffle. Background technique [0002] The existing underwater sound insulation baffles have the following defects: [0003] (1) It is not suitable for a pressure-resistant environment, or requires a more complicated inflation pipeline to solve the problem of use in a pressure-resistant environment. [0004] (2) Most of the underwater sound insulation baffles have an integrated structure, which is difficult to adapt to the use environment where the scale changes. Contents of the invention [0005] In view of the above existing problems, the applicant has made research and improvement, and provides a modular underwater pressure-resistant sound insulation baffle, which can realize underwater low-frequency pressure-resistant sound insulation, and adopts a modular structure to facilitate batch processing and modular...
