Description

Technical Field

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

[0002] Ships, as vital transportation tools, play an irreplaceable role in logistics, passenger transport, and other fields. Among these components, ventilation windows, as key parts connecting the cabin to the external environment, are primarily used for ventilating the cabin or creating an airtight space. Their performance directly affects the ship's environmental safety and operational efficiency.

[0003] In current mainstream ship ventilation window designs, ventilation openings are mostly controlled by openable and closable sealing covers. The specific drive structures are mainly divided into two categories: First, a linkage cylinder structure where multiple sealing covers on the ventilation openings are connected by rigid linkages to form a linkage mechanism. Power is provided by the cylinders, and the linkages convert linear motion into the rotational opening and closing action of the sealing covers. However, this structure has significant drawbacks: the cylinder output is linear motion, and the transmission ratio between its stroke and the rotation angle of the sealing cover is fixed, making it difficult to accurately adjust the opening angle of the sealing cover, and even more difficult to dynamically adjust the ventilation volume according to actual needs. Second, a shaft-driven structure where an actuator drives a shaft to drive a linkage, which in turn rotates the sealing cover. Because the rotation angle of the shaft and the rotation angle of the sealing cover are not synchronized, it is difficult to control the rotation angle of the sealing cover, and thus difficult to adjust the ventilation volume as needed, resulting in ventilation volume adjustment precision that fails to meet requirements.

[0004] In view of the aforementioned problems, it is necessary to design a simple, low-cost ventilation window structure for ships that can precisely control the opening angle of the sealing cover and thus control the ventilation volume. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

[0005] The objective of this invention is to provide a ventilation window structure for ships with adjustable ventilation volume, which is beneficial for improving the drive and linkage structure of the sealing cover so that the rotation angle of the rotating shaft and the sealing cover are consistent. By precisely controlling the rotation angle of the rotating shaft, the opening angle of the sealing cover can be controlled, thereby effectively controlling the ventilation volume.

[0006] The present invention achieves its objective as follows: a ventilation window structure for ships with adjustable ventilation volume 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 on both sides. A pair of connecting rods are disposed on the other side of the window body, and the connecting rods are respectively hinged to each sealing cover. The key feature is that a pair of driving arms are fixedly connected to the middle of each sealing cover on the side facing the connecting rods, and the free ends of the driving arms are respectively hinged to the connecting rods on the corresponding sides. The window frame is located on the connecting rods... A rotating shaft is rotatably supported at one side in the front-back direction. A connecting plate is fixed on the rotating shaft at a position corresponding to the connecting rod. One end of the connecting plate is fixed to the rotating shaft, and the other end of the connecting plate is hinged to the connecting rod. An angle electric actuator is fixed outside the window frame. The angle electric actuator is connected to the rotating shaft for transmission. A first lever arm L1 is formed between the hinge position of the sealing cover and the window frame and the hinge position of the corresponding drive arm and the connecting rod. A second lever arm L2 is formed between the axis of the rotating shaft and the hinge position of the connecting plate and the connecting rod. The first lever arm L1 and the second lever arm L2 are parallel to each other and have the same length.

[0007] In a specific embodiment of this utility model, the drive arm has an arc-shaped structure, and the free end of the drive arm is respectively hinged to the connecting rod via a connecting rod shaft.

[0008] In another specific embodiment of this utility model, the vent opening has a sealing edge folded around its perimeter on the side facing the sealing cover, and the sealing cover has a sealing ring embedded 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 upper two sides of the sealing cover, and the sealing cover hinge lug is respectively hinged to the window frame through a hinge shaft.

[0010] In another specific embodiment of this utility model, one end of the connecting piece is sleeved on the rotating shaft and fixedly connected by a spline, the connecting rod is provided with a connecting rod hinge lug, and the other end of the connecting piece is hinged to the connecting rod hinge lug through a connecting piece hinge shaft.

[0011] This invention employs a rotating shaft drive, and the first lever arm L1 and the second lever arm L2 are parallel to each other and have the same length. This allows the rotating shaft to maintain the same rotation angle as each sealing cover. At the same time, the rotation angle of the rotating shaft can be precisely controlled by the angle electric actuator to control the opening angle of each sealing cover, thereby effectively controlling the ventilation volume.

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.

[0015] 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.

[0016] Please see Figure 1 , Figure 2 This utility model relates to a ventilation window structure for ships with adjustable ventilation volume, including a window frame 1, a window body 11 formed inside the window frame 1, a set of ventilation openings 111 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, the upper ends of each sealing cover 2 are respectively hinged to the window frame 1; a pair of connecting rods 3 provided on the other side of the window body 11, the connecting rods 3 are respectively hinged to each sealing cover 2.

[0017] The technical innovation of this utility model is as follows: a pair of drive arms 21 are fixedly connected to the middle of the aforementioned sealing cover 2 on the side facing the connecting rod 3. The free ends of the aforementioned drive arms 21 are respectively hinged to the connecting rod 3 on the corresponding side. A rotating shaft 4 is rotatably supported on the aforementioned window frame 1 at a position next to the connecting rod 3 in the front-back direction. A connecting piece 41 is fixed on the aforementioned rotating shaft 4 at a position corresponding to the connecting rod 3. One end of the aforementioned connecting piece 41 is fixed to the rotating shaft 4, and the other end of the aforementioned connecting piece 41 is hinged to the connecting rod 3. An angle electric actuator 42 is fixed outside the aforementioned window frame 1. The aforementioned angle electric actuator 42 is connected to the rotating shaft 4 in a transmission manner. A first lever arm L1 is formed between the hinge position of the aforementioned sealing cover 2 and the window frame 1 and the hinge position of the corresponding drive arm 21 and the connecting rod 3. A second lever arm L2 is formed between the axis of the aforementioned rotating shaft 4 and the hinge position of the connecting piece 41 and the connecting rod 3. The aforementioned first lever arm L1 and second lever arm L2 are parallel to each other and have the same length. When the aforementioned electric actuator 42 drives the rotating shaft 4 to rotate, causing the connecting plate 41 to move the connecting rod 3 up and down, the aforementioned pair of connecting rods 3 can synchronously drive each sealing cover 2 to rotate by the same angle, thereby accurately controlling the opening angle of the aforementioned sealing cover 2 and effectively controlling the ventilation volume.

[0018] The aforementioned drive arm 21 has an arc-shaped structure, and the free end of the aforementioned drive arm 21 is hinged to the connecting rod 3 via a connecting rod shaft 31.

[0019] The aforementioned vent 111 has a sealing edge 1111 folded around its opening on the side facing the sealing cover 2. The aforementioned sealing cover 2 is fitted with a sealing ring 23 at the position of the corresponding sealing edge 1111.

[0020] Furthermore, a sealing cover hinge ear 22 is provided on each of the upper sides of the aforementioned sealing cover 2, and the aforementioned sealing cover hinge ear 22 is hinged to the window frame 1 through a hinge shaft 221.

[0021] One end of the aforementioned connecting piece 41 is sleeved on the rotating shaft 4 and fixedly connected by a spline. The aforementioned connecting rod 3 is provided with a connecting rod hinge ear 32. The other end of the aforementioned connecting piece 41 is hinged to the connecting rod hinge ear 32 through a connecting piece hinge shaft 321.

[0022] Please see Figure 1 and combined Figure 2When it is necessary to adjust the rotation angle of the aforementioned sealing cover 2 to control the ventilation volume, the aforementioned angle electric actuator 42 works to rotate the rotating shaft 4. The aforementioned rotating shaft 4 drives the connecting rod hinge ear 32 and the connecting rod 3 to move up or down through the connecting plate 41. The aforementioned connecting rod 3 drives the sealing cover 2 to rotate around the connecting plate hinge shaft 221 through the drive arm 21. Since the aforementioned first force arm L1 and second force arm L2 are parallel to each other and have the same length, the rotation angle of the aforementioned rotating shaft 4 is the rotation angle of the sealing cover 2, thereby achieving precise control of the rotation angle of the aforementioned sealing cover 2, and thus accurately controlling the ventilation volume.
