[0002] Louvers are an important structural component of ships and require excellent sealing performance.

[0003] Existing marine louvers have some drawbacks, such as: difficulty in opening and low sealing performance; when the louvers are opened, waves or rainwater can easily enter the hull, or they cannot prevent moisture from the humid air from entering, resulting in excessive indoor humidity; mosquitoes may enter the room when the louvers are open, affecting environmental comfort. Utility Model Content

[0004] This utility model proposes a handwheel-operated, windproof, airtight, and water-separating louver, which aims to overcome the above-mentioned shortcomings of the existing technology, making it easy to open while ensuring airtightness and preventing water and mosquitoes from entering the room.

[0005] The technical solution of this utility model is a handwheel-operated, weatherproof, airtight, and water-separating louver. Its structure includes a window frame, blades, an insect screen, a handwheel, and an air-water separator. Several parallel blades are arranged sequentially from top to bottom on the inner side of the window frame near the outside. A handwheel is located at the center of the bottom of the inner side of the window frame, connected to and controlling the opening and closing of the blades via a transmission mechanism. An insect screen covers the inner side of the window frame above the handwheel, and an air-water separator, matching the size of the insect screen, is located on the inner side of the window frame inside the screen. The handwheel controls the opening and closing of the louver blades, saving effort and providing convenience. The air-water separator effectively prevents waves or rainwater from entering the hull when the louver is open, and also allows water vapor in the air to flow down along the baffle, ensuring the incoming air is dry. The insect screen effectively prevents mosquitoes from flying into the hull and causing inconvenience when the louver is open.

[0006] Preferably, the top and bottom edges of the window frame near the outside are fixed to welding plates using mounting screws, and the welding plates are welded to the edges of the openings in the ship planks. No drilling is required in the ship planks, facilitating on-site installation, maintenance, and replacement.

[0007] Preferably, the grille blades of the air-water separator are S-shaped and arranged parallel to each other. One edge of the air-water separator is hinged to the outer edge of the window frame, and an insect screen is installed on the side of the air-water separator closer to the interior. The air-water separator is of an openable type, which facilitates the replacement and maintenance of the louvers themselves.

[0008] Preferably, the transmission mechanism includes a small connecting rod, a linkage rod, a large connecting rod, a small rocker arm, a worm gear, a transmission shaft, a gearbox, and a worm. The top two sides of each blade are rotatably connected to the window frame. A channel steel is provided at the connection between the blade and the window frame, and a sealing strip is provided inside the channel steel. One end of a small connecting rod is rotatably connected to the lower two sides of each blade. The other ends of all small connecting rods are rotatably connected to the linkage rod. The handle of the handwheel passes through the cover plate on the window frame and connects to the worm gear in the gearbox at the bottom of the inner side of the window frame. The worm gear is connected to the worm, and the worm is connected to the transmission shaft. The end of the transmission shaft is connected to a bearing seat. The transmission shaft is connected to one end of the small rocker arm, and the other end of the small rocker arm is rotatably connected to one end of the large connecting rod. The large connecting rod is rotatably connected to the bottom end of the linkage rod.

[0009] The advantages of this utility model are: reasonable structural design, handwheel-driven louver opening and closing, saving time and effort, air-water separator and insect screen to prevent water and insects from entering the room, air-water separator can rotate to facilitate louver installation and maintenance, the overall structure is recessed into the window frame with no protruding parts, and the structure is stable and safe.

The window frame 2 has several parallel blades 3 arranged from top to bottom on the inner side near the outside. The handwheel 11 is located at the bottom center of the window frame 2 near the inside. The handwheel 11 is connected to and controls the opening and closing of the blades 3 through a transmission mechanism. The window frame 2 above the handwheel 11 is covered with an insect screen 7 on the inner side near the inside. An air-water separator 9, which is the same size as the insect screen 7, is located on the inner side of the window frame 2 inside the insect screen 7.

[0017] Based on the above structure, the handwheel 11 is used to control the opening and closing of the louver blades 3, which is labor-saving and convenient, and can meet the high-density requirements; the air-water separator 9 can effectively prevent waves or rainwater from entering the hull when the louvers are open, and can also allow water vapor in the air to flow down along the baffle plate to ensure that the incoming air is dry; the insect net 7 can effectively prevent mosquitoes from flying into the hull and causing inconvenience when the louvers are open.
