Description

Technical Field

[0001] This utility model relates to the technical field of marine noise reduction devices, and in particular to a marine noise reduction device. Background Technology

[0002] In the field of marine technology, engines are the main source of vibration and noise. The high-frequency air noise and low-frequency structural vibration generated by engines seriously affect the work and living comfort of crew members and may interfere with the normal operation of precision instruments on board. Traditional noise reduction devices mostly use single sound absorption or vibration isolation structures, which have limited comprehensive noise control effects and single functions, lacking added value such as energy recovery.

[0003] Therefore, we designed a marine noise reduction device to meet the needs of practical applications. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a marine noise reduction device.

The first support is fixedly installed on the sound-absorbing panel, the first water tank is fixedly installed on the first support, the second support is fixedly installed on the sound-absorbing panel, and the second water tank is fixedly installed on the second support.

[0012] Core function: When the marine noise reduction device is in use, the air intake pipe is connected to the end of the generator exhaust pipe. Then, the first water tank and the box are filled with water. When the generator is in use, the gas noise generated will enter the curved pipe in the box through the air intake pipe. The curved pipe is designed to prolong the residence time of the gas noise.
