Embodiment Construction

[0026] The present invention is a bubble curtain / foam plate composite noise reduction method for underwater sound absorption and noise reduction, which enables the bubbles to move upward between two porous surfaces of two foam plates to form a bubble curtain, thereby realizing the bubble curtain noise reduction and foam Board Noise Reduction Composite. The following embodiments are specific devices for realizing the aforementioned compound noise reduction method.

[0027] see Figure 1 to Figure 3 , which is the first embodiment of the bubble curtain / foam plate composite device for underwater sound absorption and noise reduction of the present invention. This embodiment includes two square foam boards 1 and piping system 2. The two square foam boards are arranged oppositely and assembled into a spliced ​​wall using four connectors 5. At the same time, the two square foam boards facing each other A space is reserved between the porous surfaces; the pipeline system is arranged...

Abstract

The invention discloses a bubble curtain / foam board composite noise reduction method for underwater sound absorption and noise reduction. The method comprises the following steps: enabling bubbles to move upwards between two opposite porous surfaces of two foam boards to form a bubble curtain, and realizing the combination of bubble curtain noise reduction and foam material noise reduction. By means of the porous surface of the foam board, bubbles can be continuously refined through collision of the foam board and the foam board in the bubble rising process, and therefore the sound absorption and noise reduction effects of the bubble curtain are further enhanced; and the foam plate can support the bubble curtain, the influence of airflow and water flow on the bubble curtain is weakened, and the noise reduction effect is stabilized.

Description

technical field [0001] The invention belongs to the technical field of sound absorption and noise reduction, and in particular relates to a bubble curtain / foam board composite device and a noise reduction method for underwater sound absorption and noise reduction. Background technique [0002] Underwater construction operations, high-frequency vibration of equipment, ship navigation and missile launch will all generate a lot of noise, especially the installation and operation of offshore wind power equipment, oil exploration and actual combat drills, etc. need to be reduced to reduce noise. Health hazards of noise to marine life and those around it. [0003] At present, the commonly used underwater noise reduction methods mainly include: (1) installing a sleeve with sound-absorbing material on the vibration device as the main source of noise, but the price of the sleeve is high, and it is only applicable to some specific devices in the construction process. The application ...
