Description

Technical Field

[0001] This utility model belongs to the field of marine facility technology, specifically relating to a ventilation window structure for ships. Background Technology

[0002] As the core carrier of modern shipping, ships play an irreplaceable role in many fields, including cargo transportation and even military strategic deployment. Oil tankers undertake the majority of global crude oil transportation, chemical tankers are responsible for the safe transport of various hazardous chemicals, liquefied gas carriers focus on the transfer of gaseous energy such as liquefied natural gas, passenger ships provide convenience for people's travel, and military vessels are an important guarantee for national defense security. Ventilation windows, as an indispensable component of these ship compartments, play a crucial role in ensuring cabin air quality and maintaining cabin pressure balance. They are usually installed at the point where the compartment connects to the outside world, and can be opened for ventilation when needed, and closed in special circumstances to create an airtight environment. This is of paramount importance for ensuring the safe navigation of the ship and the safety of the people inside.

[0003] Currently, ventilation windows generally adopt the following design structure: multiple ventilation openings, each with a sealing cover, and all sealing covers are connected by a connecting rod. A cylinder pushes the connecting rod to synchronously open or close the sealing covers. However, in actual use, this structure has revealed some serious problems: due to defects in the connection between the sealing cover and the connecting rod, such as gaps at the hinge points, the sealing cover experiences significant lateral oscillation when the cylinder pushes the connecting rod to open or close. This lateral oscillation not only generates annoying noise but also causes wear and tear on the sealing cover itself, affecting its service life. Furthermore, when the sealing cover is fully open, it applies a large lateral load to the connecting rod and cylinder. This not only increases the load on the connecting rod and cylinder, affecting their normal operating performance, but may also lead to connecting rod deformation and cylinder damage, thus seriously affecting the reliability and stability of the ventilation window. Although some improvements have been made, such as adding a buffer device to the connecting rod or using multiple cylinders to work together, these measures often lead to increased operating costs or increased maintenance difficulties in actual operation, and therefore do not fundamentally solve the problem.

[0004] In view of the aforementioned problems, it is necessary to design a marine ventilation window structure that is simple in structure, low in cost, has a small cylinder oscillation amplitude, and low lateral load. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation window structure for ships, which helps to improve the connection structure between the sealing cover and the connecting rod so that the lever arm from the sealing cover rotation axis to the force point of the drive arm is symmetrical with respect to the horizontal position of the sealing cover rotation axis in both the open and closed states. This helps to reduce the swing amplitude of the cylinder and reduce the lateral load applied to the connecting rod and cylinder by the sealing cover in the open state.

[0006] The purpose of this utility model is achieved as follows: a ventilation window structure for ships includes a window frame, within which a window body is formed. The window body has a set of ventilation openings spaced apart along its height. A set of sealing covers are respectively installed on one side of the ventilation openings of the window body, with the upper ends of each sealing cover hinged to the window frame. A connecting rod is disposed on the other side of the window body, and the connecting rod is hinged to each sealing cover. A drive cylinder is provided, with one end hinged to the window frame and the other end hinged to the connecting rod. The characteristic feature is that a fixed section is located near the center of each sealing cover. A drive arm is fixedly connected to the window frame. The free end of the drive arm extends toward the connecting rod and forms an extension end that is hinged to the connecting rod. When the sealing cover is closed, the extension end extends upward to above the horizontal position X at the hinge point between the sealing cover and the window frame and forms a first lever arm L1. When the sealing cover is open, the extension end is below the horizontal position X at the hinge point between the sealing cover and the window frame and forms a second lever arm L2. The first lever arm L1 and the second lever arm L2 are symmetrical about each other with respect to the horizontal position X at the hinge point between the sealing cover and the window frame.

[0007] In a specific embodiment of this utility model, the drive arm has an arc-shaped structure, the extension end extends vertically upward when the sealing cover is closed, and the ends of the extension end are respectively hinged to the connecting rod through a connecting rod shaft.

[0008] In another specific embodiment of this utility model, the periphery of the vent opening is folded towards the sealing cover with a sealing edge, and a sealing ring is embedded in the sealing cover at the position of the corresponding sealing edge.

[0009] In another specific embodiment of this utility model, a sealing cover hinge lug is provided on each of the two sides of the upper end of the sealing cover, and the sealing cover hinge lug is respectively hinged to the window frame through a sealing cover pivot.

[0010] In another specific embodiment of this utility model, the lower end of the driving cylinder forms a cylinder seat, and the window frame is provided with a cylinder connecting seat at a position corresponding to the lower part of the cylinder seat. The cylinder connecting seat and the cylinder seat are hinged to each other. The upper end of the driving cylinder extends into a cylinder column, and the end of the cylinder column is provided with a cylinder column hinge seat. A transverse slot is opened on the cylinder column hinge seat. The connecting rod forms a connecting rod drive ear at a position corresponding to the slot and facing the cylinder. The connecting rod drive ear and the slot of the cylinder column hinge seat are hinged to each other through a connecting rod drive ear hinge shaft.

[0011] In another specific embodiment of this utility model, a first included angle α is formed between the first lever arm L1 and the horizontal position X at the hinge of the sealing cover and the window frame, and a second included angle β is formed between the second lever arm L2 and the horizontal position X at the hinge of the sealing cover and the window frame. The first included angle α and the second included angle β are the same and the included angle range is 25° to 45°.

[0012] The present invention has the following advantages after adopting the above structure: Since the force arm of the sealing cover shaft to the force point of the drive arm is symmetrical with respect to the horizontal position of the sealing cover shaft in both the open and closed states, the lateral displacement distance of the connecting rod is greatly reduced, which effectively reduces the lateral load applied to the connecting rod and cylinder by the sealing cover in the open state, and at the same time reduces the swing amplitude of the drive cylinder.

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0016] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on... Figure 1 The positions shown are for reference only and should not be construed as a particular limitation on the technical solutions provided by this utility model.

[0017] Please see Figure 1 , Figure 2 This utility model relates to a ventilation window structure for ships, including a window frame 1, within which a window body 11 is formed, and a set of ventilation openings 111 are spaced apart along the height direction of the window body 11; a set of sealing covers 2 respectively installed on the ventilation openings 111 on one side of the window body 11, with the upper ends of each sealing cover 2 respectively hinged to the window frame 1; a connecting rod 3 disposed on the other side of the window body 11, the connecting rod 3 being hinged to each sealing cover 2; and a driving cylinder 4, one end of the driving cylinder 4 being hinged to the window frame 1, and the other end of the driving cylinder 4 being hinged to the connecting rod 3.

[0018] The technical innovation of this utility model lies in the following: a drive arm 21 is fixedly connected near the center of each sealing cover 2. The free end of the drive arm 21 extends towards the connecting rod 3 and forms an extension end 211 hinged to the connecting rod 3. When the sealing cover 2 is closed, the extension end 211 extends upward to above the horizontal position X at the hinge point between the sealing cover 2 and the window frame 1, forming a first lever arm L1. When the sealing cover 2 is open, the extension end 211 is below the horizontal position X at the hinge point between the sealing cover 2 and the window frame 1, forming a second lever arm L2. The first lever arm L1 and the second lever arm L2 are symmetrical about the horizontal position X at the hinge point between the sealing cover 2 and the window frame 1. With this structure, when the drive cylinder 4 pushes or pulls the connecting rod 3, the lateral displacement distance of the connecting rod 3 is significantly reduced, the lateral load is also reduced, and the swing of the drive cylinder 4 is also reduced.

[0019] The aforementioned drive arm 21 has an arc-shaped structure. The aforementioned extension end 211 extends vertically upward when the sealing cover 2 is closed. The ends of the aforementioned extension end 211 are respectively hinged to the connecting rod 3 via a connecting rod shaft 31.

[0020] The opening of the aforementioned vent 111 has a sealing edge 1111 folded around the periphery towards the sealing cover 2, and a sealing ring 23 is embedded in the aforementioned sealing cover 2 at the position of the corresponding sealing edge 1111.

[0021] A sealing cover hinge ear 22 is provided on each side of the upper end of the aforementioned sealing cover 2. The aforementioned sealing cover hinge ear 22 is hinged to the window frame 1 through a sealing cover pivot 221.

[0022] The lower end of the aforementioned drive cylinder 4 is provided with a cylinder seat 42. The aforementioned window frame 1 is provided with a cylinder connecting seat 12 at a position corresponding to the lower part of the cylinder seat 42. The aforementioned cylinder connecting seat 12 is hinged to the cylinder seat 42. The upper end of the aforementioned drive cylinder 4 extends with a cylinder column 41. The end of the aforementioned cylinder column 41 is provided with a cylinder column hinge seat 411. A transverse slot 4111 is opened on the aforementioned cylinder column hinge seat 411. The aforementioned connecting rod 3 is provided with a connecting rod drive ear 32 at a position corresponding to the slot 4111 and facing the cylinder 4. The aforementioned connecting rod drive ear 32 and the slot 4111 of the cylinder column hinge seat 411 are hinged to each other by a connecting rod drive ear hinge shaft 321.

[0023] A first angle α is formed between the first lever arm L1 and the horizontal position X at the hinge point between the sealing cover 2 and the window frame 1. A second angle β is formed between the second lever arm L2 and the horizontal position X at the hinge point between the sealing cover 2 and the window frame 1. The first angle α and the second angle β are the same and their range is 25° to 45°. In this embodiment, the angle between the first angle α and the second angle β is selected to be 30°.

[0024] Please continue reading. Figure 1 and combined Figure 2 When the aforementioned sealing cover 2 needs to be closed, the aforementioned cylinder 4 operates, causing the cylinder column 41 to move upward, pushing the connecting rod drive ear 32 and the connecting rod 3 upward. The aforementioned connecting rod 3, through the drive arm 21, drives the sealing cover 2 to rotate around the sealing cover pivot 221 towards the corresponding sealing mating edge 1111 and seal the connection. Since the aforementioned first force arm L1 and second force arm L2 are symmetrical about the horizontal position X of the hinge point between the sealing cover 2 and the window frame 1, the lateral displacement generated by the drive arm 21 pushing the connecting rod 3 during the rotation of the sealing cover 2 is small, and the resulting lateral load is also reduced, avoiding large swinging of the aforementioned cylinder 4. When the aforementioned sealing cover 2 is opened, the process is reversed, similarly reducing the lateral displacement generated by the drive arm 21 pushing the connecting rod 3 during the rotation of the sealing cover 2, and also reducing the resulting lateral load, avoiding large swinging of the aforementioned cylinder 4.
