Description

Technical Field

[0001] This utility model relates to the field of ventilation grille technology, and in particular to a quick-closing device for a staggered ventilation grille in a marine engine room. Background Technology

[0002] Ship engine rooms require natural ventilation to improve engine efficiency. However, when a fire occurs in the engine room, the ventilation openings need to be quickly closed to keep them sealed when the fire suppression system is activated. In existing technologies, the structure of the ventilation openings prevents them from closing quickly, which affects the timely execution of fire suppression work and causes unnecessary losses. To address this, we propose a ship engine room ventilation opening grid-interlocking quick-closing device. Utility Model Content

[0003] This utility model provides a quick-closing device for interlocking grilles of marine engine room ventilation openings, which solves the above-mentioned technical problems.

[0004] The present invention provides the following solution to the above-mentioned technical problems: A marine engine room ventilation grille interlocking quick-closing device includes a fixed plate, wherein fixed strips are respectively arranged laterally on the upper and lower parts of the fixed plate, and the fixed strips are fixedly connected to the fixed plate by multiple screws. A movable plate is slidably fitted on the outer wall of the side of the fixed plate opposite to the fixed strips. Grille openings penetrating through the fixed plate and the movable plate are evenly arranged on the fixed plate and the movable plate respectively. A movable bracket is fixedly connected to the movable plate. A fixed piece is arranged laterally on the lower part of the fixed plate. A limiting piece is arranged on the lower part of the movable bracket and slidably fitted with the upper surface of the fixed piece. The fixed piece is inserted and fixed to the limiting piece by a locking buckle.

[0005] Preferably, the upper and lower surfaces of the movable plate are respectively slidably fitted with auxiliary strips, and the auxiliary strips are movably sleeved on the outer wall of the screw.

[0006] Preferably, L-shaped connectors are vertically fixedly installed at both ends of the movable plate, and the connectors are fixedly connected to the movable bracket by nuts.

[0007] The beneficial effects of this utility model are:

[0008] A fixed plate is installed and fixedly connected to the cabin. A movable plate is placed between the fixed plate and the cabin wall, allowing the movable plate to slide and adjust. By adjusting the position of the movable plate, the overlap or misalignment of the grille openings on the movable plate and the fixed plate is controlled, thereby opening or closing the ventilation openings. When the grille openings overlap, the ventilation openings are in the open state, and when the grille openings are misaligned, the ventilation openings are in the closed state. The left and right sliding of the movable plate forms quick closing and opening, and the movable plate is fixed by a quick-release locking buckle.

[0009] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. The specific implementation methods of this utility model are given in detail in the following embodiments and their accompanying drawings. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0018] like Figure 1-4As shown, this utility model discloses a quick-closing device for a marine engine room ventilation grille with a staggered design. It includes a fixed plate 1, with fixing strips 2 horizontally arranged on the upper and lower parts of the fixed plate 1. The fixing strips 2 protect the fixed plate 1, directing the screws onto the fixing strips 1 instead of the plate 1, thus protecting the plate 1 and evenly distributing the force. The fixing strips 2 are fixedly connected to the fixed plate 1 by multiple screws. A movable plate 3 is slidably fitted onto the outer wall of the fixed plate 1 on the side opposite to the fixing strips 2. The movable plate 3 and the fixed plate 1 are each evenly provided with grille openings 4 penetrating through it. The movable plate 3 is fixedly connected to a movable bracket 5. A fixing piece 6 is horizontally arranged on the lower part of the fixed plate 1. A limiting piece 7 is slidably fitted onto the upper surface of the fixing piece 6 on the lower part of the movable bracket 5. The fixing piece 6 is fixedly connected to the limiting piece 7 by a locking buckle 8. This device, by setting up a fixed plate 1 and a movable plate 3, allows for the opening and closing of the ventilation opening by adjusting the position of the movable plate 3 and utilizing the overlap or stagger of the grille openings 4 on the movable plate 3 and the fixed plate 1, making the closure of the ventilation opening faster and more convenient.

[0019] Specifically, auxiliary strips 9 are slidably fitted on the upper and lower surfaces of the movable plate 3, and the auxiliary strips 9 are movably sleeved on the outer wall of the screw. The auxiliary strips 9 are set between the fixed plate 1 and the cabin wall to reduce the wear of the fixed plate 1, and at the same time make the fit between the fixed plate 1 and the cabin wall tighter and the sealing effect better.

[0020] More specifically, L-shaped connectors 10 are vertically fixed at both ends of the movable plate 3. The connectors 10 are fixedly connected to the movable bracket 5 by nuts. The connectors 10 help to connect and fix the movable plate 3 to the movable bracket 3, making it convenient for the connectors 10 to connect to the movable bracket 3.

[0021] Working principle:

[0022] The fixed plate 1 is connected and fixed to the cabin wall. The movable plate 3 is set between the fixed plate 1 and the cabin wall. The movable plate 3 slides with the fixed plate 1 and the cabin wall. Moving the movable plate 3 can control the overlap or offset of the grille opening 4 on the movable plate 3 and the fixed plate 1, so as to realize the opening and closing of the ventilation opening. When the grille opening overlaps, it is in the open state. When the grille opening is offset, it is in the closed state, making the opening and closing of the ventilation opening more convenient and quick. The movable plate 3 is fixed by the locking buckle 8 to ensure the stable misalignment of the movable plate 3 and the fixed plate 1, so as to achieve the stable closure of the ventilation opening.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
