Fireproof and light-shielding pneumatic shutter for ship
By using metal fireproof light-shielding panels and linkage mechanisms in ship louvers, a continuous light-shielding surface and a multi-level light-shielding structure are formed, solving the problem of light-shielding failure of louvers in a fire, achieving high safety and stability, and making it suitable for ship fire prevention and ventilation systems.

AI Technical Summary
Existing ship louvers are flammable, melt, or carbonize in high-temperature fire environments, leading to shading failure and loss of fire protection integrity. Furthermore, traditional structures lack multi-level shading design, making them unable to effectively block the spread of flames, heat radiation, and smoke.
The fireproof light-shielding panel made of non-combustible metal material is interlocked with the louvers to form a continuous light-shielding surface. Combined with the metal light-shielding base and reflective cavity structure, it achieves multi-level light shielding and sealing. The linkage mechanism enables the louvers to rotate synchronously and is equipped with emergency manual operation.
It effectively blocks the spread of flames, heat radiation and smoke under extreme conditions such as fire, improves light shielding and airtightness and fire protection integrity, adapts to harsh ship environments, and has automated and emergency manual functions.
