Description

Technical Field

[0001] This utility model belongs to the field of marine ventilation technology, and specifically relates to a marine ventilation structure. Background Technology

[0002] During navigation, ships rely on ventilation systems to exchange air between the interior and exterior of the cabins, ensuring the health of the crew and the normal operation of equipment. However, in the marine environment, sea breezes often carry high-salinity water vapor (salt spray) and odors (such as the smell of fish). Most existing ventilation structures only provide basic air exchange and lack effective mechanisms to deal with salt spray and odors. This allows humid air carrying corrosive salts and odor molecules to directly enter the cabins, accelerating the corrosion of metal equipment and the mold growth of non-metallic interiors, damaging cargo, and causing long-term exposure to the salty environment to affect the comfort and health of the crew, even threatening the safety and economy of navigation. Although some improved designs attempt to integrate filtration units, these often have fixed structures, are inconvenient to maintain, and cannot be flexibly adapted to different ship layouts, making it difficult to completely solve the problems of salt spray condensation and odor residue. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a ship ventilation structure.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A ship ventilation structure includes an air intake duct, the outer cover of which is provided with a protective cover, and the outlet end of the air intake duct is connected to the inlet end of an L-shaped air duct; an mounting plate is provided on the outer wall of the L-shaped air duct, and a mounting base is fixedly installed at the bottom of the air intake duct; a dehumidification mechanism is detachably installed at the inlet end of the L-shaped air duct, and an odor removal mechanism is detachably installed at the outlet end of the L-shaped air duct.

[0005] Preferably, the mounting base and mounting plate are fixedly installed on the deck of the ship's hull via threaded holes.

[0006] Preferably, the suction duct is provided with a support plate inside, and a drive motor is installed on the support plate. The power output end of the drive motor is connected to a fan blade, which rotates in reverse to achieve the suction effect. The outlet end of the suction duct is provided with a mounting flange, which is connected to an L-shaped air delivery duct.

[0007] Preferably, the protective cover is fixed to the front of the suction tube by rivets.

[0008] Preferably, the L-shaped air duct is provided with an air inlet and an air outlet.

[0009] Preferably, the dehumidification mechanism includes a dehumidification cylinder shell, the inside of which is filled with moisture-absorbing cotton, and the dehumidification cylinder shell is detachably connected to an L-shaped air duct via a first connecting plate.

[0010] Preferably, the deodorization mechanism includes a frame, in which multiple activated carbon plates are embedded, and a baffle is provided on the outside of the frame. The air outlet of the frame is detachably connected to an L-shaped air duct through a second connecting plate.

[0011] Preferably, the portion of the L-shaped air duct below the mounting plate is located inside the hull, and the length of the L-shaped air duct can be extended as needed to place the exhaust port of the deodorization mechanism in a suitable position.

[0012] This utility model's technical solution effectively addresses high salinity and odors at sea by integrating dehumidification and deodorization mechanisms. The moisture-absorbing cotton within the dehumidification mechanism absorbs a large amount of moisture from the air, significantly reducing humidity and thus minimizing salt spray condensation on equipment surfaces, delaying corrosion of metal parts and mold growth on non-metallic materials. The activated carbon plate in the deodorization mechanism utilizes its porous structure and strong adsorption properties to thoroughly remove odor molecules from the sea breeze, such as the fishy smell, improving cabin air quality and preventing odors from affecting crew comfort and health. Furthermore, a protective cover prevents external debris from entering the system, while the drive motor and fan blades provide stable airflow, ensuring ventilation efficiency. Mounting brackets, mounting plates, threaded holes, and rivets ensure the structure is securely installed on the deck, adapting to the ship's swaying environment. The extendable design of the L-shaped air duct allows adjustment of the exhaust outlet position according to the actual cabin layout, ensuring that treated air is delivered to the required areas. The modular design of the overall structure facilitates maintenance and replacement, reducing long-term operating costs. Attached Figure Description
