Fireproof door for ship sound absorption and insulation device

Technical Field

The utility model relates to a naval vessel is with noise elimination sound insulation cabin structure especially relates to a prevent fire door that has fire-retardant fire prevention and noise elimination function of making an uproar falls for constituting naval vessel noise elimination sound insulation cabin.

Background

With the continuous upgrading and upgrading of ships in design and construction, the number of ship-borne equipment is continuously increased, the noise problem in the cabin environment is gradually revealed, and the size of cabin air noise becomes an important index for measuring the habitability of ships, so that people pay more and more attention to the noise. Because the cabin of a ship is often narrow in space and complicated in noise source, electromechanical equipment of main and auxiliary machines, an air conditioning ventilation pipeline system, a water pipeline system and structural vibration are factors which affect the noise of the cabin of the ship.

The cabin door of the ship cabin is also an important way for noise diffusion and propagation, the prior sound insulation structure of the cabin door of a real ship is applied mostly by some conventional passive noise reduction technical measures, and for a cabin door of a living cabin, sound insulation mineral wool is mainly directly filled in a cabin door cavity, so that the mode is simple in design and installation and wide in application range, but the sound insulation structure is single, only 5-7 dB (A) can be reduced, the strict sound insulation and noise elimination technical requirements of the modern ship cannot be met, and the strict cabin noise index cannot be met. The existing cabin door has not only a poor noise reduction and sound insulation effect, but also insufficient safety performance such as fire prevention, heat insulation and the like, and is very unsafe especially when a door lock cannot be opened in case of fire and cabin personnel do not have a passage for passing or escaping.
