Description

Technical Field

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

[0002] Fixed louvers on ships are primarily used for ventilation and exchange within cabins or areas, ensuring air circulation. As a core component of the natural ventilation system, louvers must be able to seal off from rain and wind when closed, without allowing light or gaps, and prevent leakage of rainwater, sea waves, and CO2 fire extinguishing gases.

[0003] Traditionally, fixed louvers are located on the exterior of the cabin, with piping connecting the interior to various rooms to ensure air quality. However, with the increasing number of LNG and methanol bunkering vessels in recent years, ventilation for some specialized cabins has been diverted to the outer hull area, requiring the corresponding louvers to be fixed to the inside of the ship's outer plating. When one end of a fixed louver is connected to the ship's outer plating and the other end to the piping from the cabin, an additional structural box is usually needed to connect the louvers and the cabin piping in series. This undoubtedly increases the amount of professional coordination required and adds to the ship's weight. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a special ventilation structure for ship cabins that not only meets the ventilation requirements of ship cabins but also, through special customization, can accommodate various selection and matching of cabin piping. It is simple and practical, reduces the construction period, and meets shipbuilding specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A special cabin ventilation structure for ships includes an exhaust vent on the outer side plating of the ship. The ventilation structure is located inside the exhaust vent and includes an exhaust box, fixed louvers, and a connecting pipe. The side of the exhaust box near the exhaust vent is open, while the opposite side is closed. The exhaust box is detachably connected to the outer side plating. The fixed louvers are fixed inside the exhaust box at one end near the exhaust vent. The connecting pipe is fixed to the bottom wall of the exhaust box located inside the fixed louvers and communicates with the interior of the exhaust box.

[0006] Furthermore, multiple nuts are fixed on the inner wall of the outer side plate located around the vent, and a flange is fixed on the outer side wall of the open end of the vent box. The vent box is detachably connected by the flange, nuts, and bolts.

[0007] Furthermore, a gasket is provided between the flange and the nut.

[0008] Furthermore, the outer wall of the fixed louver is tightly and fixedly connected to the inner wall of the exhaust box.

[0009] Furthermore, the section of the exhaust box away from the outer side panel is an open structure, and a flange is fixed on the outer side wall of this end. The flange is detachably connected to a blind flange by bolts.

[0010] Furthermore, the upper end of the connecting pipe extends into the interior of the exhaust box, and the vertical distance between the upper end face of the connecting pipe and the inner bottom surface of the exhaust box is not less than 50mm.

[0011] Furthermore, a flange is fixed on the lower outer wall of the connecting pipe, and a flange is fixed on the outer wall of the compartment exhaust duct or rectangular duct near the connecting pipe. The lower end of the connecting pipe is detachably connected to the compartment exhaust duct or rectangular duct through the flange.

[0012] Furthermore, the number of the takeovers is at least one.

[0013] This utility model's special ship compartment ventilation structure eliminates the need to connect louvers and compartment piping in series via a hull structure box. In actual ship modeling, it allows for more flexible selection of installation locations, reducing structural coordination requirements. It also effectively solves the problems associated with areas where a hull structure box cannot be constructed. Furthermore, for fixed louvers installed on the ship's outer plating, inspection and maintenance are more convenient, reducing maintenance costs and improving construction quality.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3As shown, a special cabin ventilation structure for a ship has an exhaust vent on the outer side plating 4 of the ship. The ventilation structure is located inside the exhaust vent and includes an exhaust box 1, fixed louvers 2, and a connecting pipe 3. The side of the exhaust box 1 near the exhaust vent is open, while the opposite side is closed. The exhaust box 1 is detachably connected to the outer side plating 4. The fixed louvers 2 are fixed inside the exhaust box 1 at the end near the exhaust vent. The connecting pipe 3 is fixed to the bottom wall of the exhaust box 1 located inside the fixed louvers 2 and communicates with the interior of the exhaust box 1.

[0020] In some embodiments, the number of the pipes 3 is at least one, and when there are multiple pipes 3, the multiple pipes 3 are spaced apart along the width direction of the exhaust box 1.

[0021] It should be noted that the connecting pipe 3 can be made into a corresponding shape, such as square, double joint, triple joint, etc., depending on the diameter and flow area of ​​the pipe coming out of the compartment.

[0022] Specifically, multiple nuts 6 are fixed on the inner wall of the outer side plate 4 located around the vent, and a flange 7 is fixed on the outer side wall of the open end of the vent box 1. The vent box 1 is detachably connected by the flange 7, nuts 6 and bolts.

[0023] Furthermore, a gasket 9 is provided between the flange 7 and the nut 6.

[0024] Furthermore, the outer wall of the fixed louver 2 is tightly and fixedly connected to the inner wall of the exhaust box 1.

[0025] Furthermore, the section of the exhaust box 1 away from the outer side plate 4 is an open structure, and a flange 7 is fixed on the outer side wall of this end. The flange 7 is detachably connected to a blind flange 5 by bolts.

[0026] With this setup, when the side-fixed louver 2 needs maintenance, it is not necessary to carry out the work outside the ship. The fixing bolts of the end box of the side-fixed louver 2 can be removed directly, the blind flange 5 can be opened, and the internal condition of the side-fixed louver 2 can be observed, and the relevant parts can be repaired.

[0027] Furthermore, in order to prevent a small amount of rainwater from entering the louvers, the upper end of the connecting pipe 3 extends into the interior of the exhaust box 1, and the vertical distance between the upper surface of the connecting pipe 3 and the inner bottom surface of the exhaust box 1 is not less than 50mm.

[0028] Furthermore, a flange 7 is fixed on the lower outer wall of the connecting pipe 3, and a flange 7 is fixed on a section of the outer wall of the cabin exhaust duct or rectangular duct 8 near the connecting pipe 3. The lower end of the connecting pipe 3 is detachably connected to the cabin exhaust duct or rectangular duct 8 through the flange 7.

[0029] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
