Louver blade of ship

Abstract

The invention discloses a louver blade of a ship, and belongs to the technical field of ship accessories. The louver blade comprises an air guide plate and a water blocking plate; the shape of the cross section of the air guide plate is in a semicircular arc shape, and an air guide plate cavity of the air guide plate faces downwards under a use state, the left side in the length direction of the air guide plate is folded towards the air guide plate cavity to be provided with an air guide plate cavity water drop interception groove folded edge, and the space between the opposite sides of the air guide plate cavity water drop interception groove folded edge and the air guide plate is formed into an air guide plate cavity water drop interception groove; and the water blocking plate and the side, facing away from the air guide plate cavity, of the air guide plate are fixed at the position corresponding to the left side in the length direction of the air guide plate, the right side in the length direction of the water blocking plate extends to be provided with a water blocking plate wing, the space between the water blocking plate wing and the side, facing away from the air guide platecavity, of the air guide plate forms a water blocking groove, and the left side in the length direction of the water blocking plate extends out of the left side edge of the air guide plate in a downward inclined state. The air guide cavity is guaranteed to reflect a good ventilation effect, and water drops can be ideally intercepted; and when strong wind and big waves are encountered, the water blocking groove of the water blocking plate wing plays an excellent role in water blocking.

Description

technical field [0001] The invention belongs to the technical field of ship accessories, and in particular relates to a shutter blade of a ship. Background technique [0002] According to professional knowledge, shutters are usually equipped on ships such as the crew room, engine room, cockpit, etc., and the shutters are usually composed of a window frame (also called "window") and louver blades arranged on the window frame. There is no lack of technical information related to ship shutters in the published Chinese patent documents, such as CN201923314U (new ventilation grille for ships), CN205713831U (a kind of shutter for ships), CN203879346U (shutter shutter opening and closing device for ship engine room), etc. CN104563816B (adjustable louver structure for ship cabins), CN205769996U (shutter with manual waterproof cannon device for ships), CN205713834U (louver with pneumatic waterproof cannon device for ships), CN109441315A (aerodynamic weather-tight louver structure for...

AI Technical Summary

Problems solved by technology

However, the ship louver blades in the prior art, including the aforementioned patents, are generally difficult to meet the desired air-water separation effect in the industry. Embodies the ultimate water and gas separation effect

[0003] Authorized announcement number CN205713831U recommends "marine air inlet guide type blade shutters". This patent changes the rectangular cross-sectional shape of the blades in the prior art into a substantially ∧-shaped cross-sectional shape. For details, please refer to the patent. In paragraphs 0024 to 0029 of the specification, blades of this shape can objectively reflect the technical effects of the four aspects recorded in paragraphs 0014 to 0017 of the specification, but for the interception of water droplets integrated by water vapor and the generation of waves caused by wind and waves The blocking of water does not seem to have an advantage, and the technical solution to be introduced below is produced under this background
