Abstract
Description
Technical Field
[0001] This application relates to the technical field of ships, and particularly to a hatch door and a ship. Background Art
[0002] Watertight doors are key safety devices for ship compartment separation, mainly used to block the spread of seawater in case of accidents such as ship collisions and groundings, ensuring the watertightness of the hull and navigation safety.
[0003] Currently, it is often difficult to balance the sealing performance and ventilation requirements of watertight doors. To ensure watertightness, watertight doors with a fully enclosed rigid structure and a pressing device to compress the sealing surface are mostly used. Although such designs can effectively block seawater during immersion, they will block the ventilation of the compartment after being completely closed. For some watertight doors that also take into account the ventilation function, although ventilation holes are opened in the door panel, the holes will seriously weaken the strength of the sealing structure, resulting in a decline or even loss of watertightness. It can be seen that it is currently difficult to simultaneously meet the strict requirements of maritime safety regulations for watertightness and the daily ventilation requirements of the compartment.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0022] The present application discloses a hatch door, which includes: a door frame, a door body, a window frame, an inner edge frame, a first window unit, and a second window unit; the door frame is installed on the opening of the cabin body; the door body is hinged to the door frame; at least one window is provided on the door body; the window frame is installed on the window of the door body; the inner edge frame is connected to the side of the window frame close to the interior of the cabin body and protrudes towards the interior of the cabin body; the first window unit is selectively openably and closably connected to the side of the window frame close to the exterior of the cabin body; the second window unit is installed on the side close to the interior of the cabin body within the inner edge frame; when the air supply direction is from the interior of the cabin body to the exterior of the cabin body, the second window unit separates the interior of the cabin body; when the air supply direction is from the exterior of the cabin body to the interior of the cabin body, the second window unit communicates with the interior of the cabin body.
[0023] In the present application, the first window unit can be selectively opened and closed as needed, and at the same time, in cooperation with the second window unit, it meets the need for one-way air supply inside the cabin. While meeting the airtightness of the door body, it can also meet the ventilation needs inside the cabin according to the scene requirements.
[0024] Figure 1 It is a front view structural schematic diagram of the hatch door provided by an embodiment of the present application. Figure 2 It is a side view structural schematic diagram of the hatch door provided by an embodiment of the present application. Figure 3 For Figure 2 The partial enlarged structural schematic diagram of area A in Figures 1 to 3 As shown in the figure, an embodiment of the present application provides a hatch door, which includes: a door frame 100, a door body 200, a window frame 400, an inner edge frame 410, a first window unit 500, and a second window unit 600; the door frame 100 is installed on the opening of the cabin body; the door body 200 is hinged to the door frame 100 through a first hinge 300; at least one window is provided on the door body 200; the window frame 400 is installed on the window of the door body 200; the inner edge frame 410 is connected to the side of the window frame 400 close to the interior of the cabin body and protrudes towards the interior of the cabin body; the first window unit 500 is selectively openably and closably connected to the side of the window frame 400 close to the exterior of the cabin body; the second window unit 600 is installed on the side close to the interior of the cabin body within the inner edge frame 410; when the air supply direction is from the interior of the cabin body to the exterior of the cabin body, the second window unit 600 separates the interior of the cabin body; when the air supply direction is from the exterior of the cabin body to the interior of the cabin body, the second window unit 600 communicates with the interior of the cabin body.
[0025] In an optional embodiment, the second window unit 600 includes: a plurality of rotating shafts 610 and a plurality of grating plates 620.
[0026] Multiple rotating shafts 610 are distributed parallel to each other along the longitudinal direction of the inner frame 410, and each rotating shaft 610 is rotatably installed in the inner frame 410; a grid plate 620 is installed on each rotating shaft 610, and adjacent grid plates 620 overlap each other.
[0027] When the air supply direction is from the outside of the cabin to the inside of the cabin, the intake air flow drives the grille 620 to rotate counterclockwise as shown in the reference diagram. At this time, an air supply gap is formed between adjacent grilles 620, and the intake air flow can enter the cabin from the outside to meet the ventilation needs in the cabin.
[0028] When the air supply direction is from the inside of the cabin to the outside of the cabin, the intake air flow pushes the grille 620 to rotate so that adjacent grilles 620 overlap each other. Referring to the figure, after the adjacent grilles 620 overlap, the grille 620 can no longer rotate clockwise. At this time, no air supply gap can be formed between the adjacent grilles 620, and the intake air flow cannot be delivered from the inside of the cabin to achieve sealing inside the cabin.
[0029] In this embodiment, the grille 620 relies on its own gravity to open and close the grille 620. Here, the grille 620 needs to have a certain weight. The intake airflow can move the grille 620. When the intake airflow is configured, it is at least the minimum ventilation volume that can meet the ventilation needs of the cabin. That is to say, when the ventilation volume is less than the minimum ventilation volume, the grille 620 is not easy to move due to external factors such as bumps and shakes due to its heavy weight, so as to ensure the sealing of the cabin.
[0030] Furthermore, a hook 621 structure is provided at the end of the grid plate 620, and the hooks 621 of adjacent grid plates 620 are mutually engaged. This can make the connection between adjacent grid plates 620 more stable to cope with the situation of large intake air flow.
[0031] Furthermore, a limit block and a limit baffle are also provided in the second window unit 600, the limit block is provided on the rotating shaft 610, and the limit baffle is provided on the inner edge frame 410 (the limit baffle can also be provided on the rotating shaft 610, and the limit block is provided on the inner edge frame 410), and the contact between the limit block and the limit baffle limits the continuous rotation of the rotating shaft 610 to limit the opening of the grid plate 620, so as to avoid the problem of the grid plate 620 flipping due to excessive flipping when the intake air flow is large. Here, the position where the limit block and the limit baffle are provided needs to ensure that the rotation angle of the rotating shaft can be between 100° and 120°.
[0032] refer to Figure 3As shown in the figure, four rotating shafts 610 and four grid plates 620 are arranged from top to bottom, a transition beam is arranged in the middle position on the inner edge frame 410, and the upper and lower ends of the transition beam are also provided with hook 621 structures that cooperate with the grid plates 620. Referring to the figure, it can be seen that the lower end of the grid plate 620 located above the transition beam is connected to the transition beam through the hook 621.
[0033] What needs to be explained here about the rotating shaft 610 is that it should be noted that the assembly between the rotating shaft 610 and the inner edge frame 410 needs to ensure that the movement of the rotating shaft 610 is smooth.
[0034] In an optional embodiment, a bushing is mounted on the end of the rotating shaft 610, and the bushing is installed between the rotating shaft 610 and the inner edge frame 410. In this way, the problem of reduced positioning accuracy due to wear between the rotating shaft 610 and the inner edge frame 410 can be suppressed, so that the rotation accuracy of the grid plate 620 remains stable for a long time. Here, the selection of the materials of the rotating shaft 610 and the bushing generally considers that the wear resistance and corrosion resistance of the material selected for the bushing are better than the material selected for the rotating shaft 610. For example, the material of the rotating shaft 610 can be 316 stainless steel, and the material of the bushing can be bronze.
[0035] Furthermore, an oil nozzle is provided at the installation position of the rotating shaft 610 or at the position where the bushing is installed on the rotating shaft 610 , and the oil nozzle is used to lubricate the installation position of the rotating shaft 610 or at the position where the bushing is installed on the rotating shaft 610 .
[0036] Here, it is also necessary to explain that the grid plate 620 can be selected to have a thickness of 0.5 mm to 1.5 mm. The material of the grid plate 620 generally needs to be a material with strong corrosion resistance, not easy to rust, and easy to clean. Generally, stainless steel materials can be selected, such as 304 stainless steel, 306 stainless steel, etc., and the materials listed here are not limited.
[0037] In one embodiment, the second window unit 600 also includes: a controller. The controller is connected to the plurality of rotating shafts 610 for controlling the movement of each rotating shaft 610. In this embodiment, the controller achieves precise adjustment of the ventilation volume by precisely controlling the inclination angle of the grille 620. It should be noted here that the controller can control the movement of each rotating shaft 610 to be consistent (i.e., the inclination angles of the grille 620 are consistent), or it can control each rotating shaft 610 to move independently, i.e., the inclination angles of each grille 620 are inconsistent). Specifically, the controller can be installed in the inner edge frame 410, or it can be installed in a suitable position inside or outside the cabin that does not interfere with other devices. Here, it is ensured to be installed within the stable range of the communication distance as much as possible, and no other restrictions are imposed.
[0038] In one embodiment, the second window unit 600 further includes: a controller and a sensing device. The controller is communicatively connected to the plurality of rotating shafts 610 and is configured to control the actions of the respective rotating shafts 610. The sensing device is communicatively connected to the controller and is configured to collect environmental information inside the cabin and feed it back to the controller, where the environmental information is configured as one or more of the temperature, humidity, target gas concentration, and real-time ventilation volume inside the cabin. Specifically, the sensing device should generally be installed inside the cabin to more accurately collect the environmental information inside the cabin.
[0039] Here, the sensing device can be a wind speed sensor for collecting the real-time ventilation volume inside the cabin. The controller can generate the rotation angles of the respective rotating shafts 610 based on the difference between the real-time ventilation volume collected by the sensing device and the preset target ventilation volume, and control the start and stop of the actions of the rotating shafts. Specifically, when the real-time ventilation volume collected by the sensing device is less than the preset target ventilation volume, the controller controls the respective rotating shafts to rotate counterclockwise by 50° to increase the ventilation gap between adjacent grating plates 620. The sensing device continuously collects the real-time ventilation volume and feeds it back to the controller. If the controller determines that the difference between the continuously collected real-time ventilation volume by the sensing device and the preset target ventilation volume does not show a decreasing trend, indicating that the opening degree between the grating plates is still insufficient at this time, the controller controls the respective rotating shafts to rotate counterclockwise by another 40° to further increase the ventilation gap between adjacent grating plates 620 until the difference between the real-time ventilation volume collected by the sensing device and the preset target ventilation volume is zero. Thereafter, the controller controls the respective rotating shafts to rotate clockwise by 90° to make the grating plates return to the closed state.
[0040] Here, the sensing device can be a temperature sensor. The temperature sensor collects the temperature inside the cabin and feeds it back to the controller. When the temperature inside the cabin received by the controller exceeds the preset target temperature, the controller increases the tilt angle of the grating plate 620 by controlling the action of the rotating shaft 610 to increase the ventilation volume and meet the cooling requirement inside the cabin. Correspondingly, the sensing device can also be a humidity sensor. The humidity sensor collects the humidity inside the cabin and feeds it back to the controller. When the humidity inside the cabin received by the controller exceeds the preset target humidity, the controller increases the tilt angle of the grating plate 620 by controlling the action of the rotating shaft 610 to increase the ventilation volume and meet the ventilation and dehumidification requirement inside the cabin.
[0041] Here, the sensing device can be a smoke sensor. The smoke sensor collects the target gas concentration inside the cabin and feeds it back to the controller. When the target gas concentration inside the cabin received by the controller exceeds the preset target gas concentration, the controller reduces the tilt angle of the grating plate 620 by controlling the action of the rotating shaft 610 until the grating plate 620 is in the closed state to prevent the spread of smoke.
[0042] It should be noted here that the selection of the sensing device is not limited to the above examples, and any automatic sensing device that can collect the internal environment information of the cabin can be selected, and no specific examples will be given here.
[0043] In one embodiment, it further includes: a shutter 700. The shutter 700 is installed on one side of the inner edge frame 410 close to the interior of the cabin. In this embodiment, the shutter 700 includes a plurality of inclined blades. The side of the blade close to the interior of the cabin is higher than the side of the blade close to the exterior of the cabin. With such a setting of the blades, when there are water droplets or the like falling outside the cabin, due to the blocking of the blades, the water droplets will only drip onto the blades and flow down along the blades to the outside of the cabin, achieving the effect of preventing water from entering the interior of the cabin. It should be noted that the inclination angle between adjacent blades can be fixed or selectively adjustable. Here, the example is that the inclination angle between adjacent blades can be fixed. For the embodiment of adjusting the inclination angle between adjacent blades, a transmission device needs to be provided to realize the opening and closing movement of the blades, which will not be specifically elaborated here. However, if it involves the control of the transmission device, it can be communicatively connected to the above-mentioned controller to achieve automatic control.
[0044] In one embodiment, it further includes: a mesh panel 800. The mesh panel 800 is installed on one side of the window frame 400 close to the exterior of the cabin. Specifically, the mesh panel 800 can be located between the window frame 400 and the inner edge frame 410. By setting the mesh panel 800, it can prevent insects, mice, etc. from entering the interior of the cabin through the inner edge frame 410.
[0045] In an alternative embodiment, it further includes: an air regulating plate. The upper and lower ends of the air regulating plate are rotatably installed on the inner edge frame 410 through shafts, and the ventilation volume is adjusted by changing the angle between the air regulating plate and the air supply direction. Specifically, when the air regulating plate is parallel to the air supply direction, the ventilation volume is the largest. When the air regulating plate is perpendicular to the air supply direction, the ventilation volume is the smallest.
[0046] Furthermore, a limiting piece is provided on the air regulating plate to limit the rotation movement of the air regulating plate.
[0047] The structure of the first window unit 500 will be specifically introduced. The first window unit 500 includes: a cover plate 510, a buckle 520, and a handle 550. The cover plate 510 is hinged to the window frame 400 through a second hinge 530; the buckle 520 is installed on the outer wall of the window frame 400 and presses against the cover plate 510. Here, to open and close the cover plate 510, the buckle 520 needs to be manually loosened so that the buckle 520 no longer presses against the cover plate 510, and then the handle 550 is pulled to open the cover plate 510.
[0048] In an optional embodiment, the first window unit 500 further includes a sealing member 540. The sealing member 540 is sandwiched between the cover plate 510 and the window frame 400 to ensure the airtightness requirements inside and outside the cabin.
[0049] In one embodiment of the present application, a ship is provided, comprising the hatch as described above.
[0050] Optionally, when the hatch is used in a ship power compartment, since a large amount of heat and harmful gases will be generated when the equipment in the ship power compartment is in operation, after the cover is opened, the intake airflow drives the grid plate 620 to rotate so that an air supply gap is formed between adjacent grid plates 620, and fresh air can enter the ship power compartment and maintain a suitable temperature and air quality in the ship power compartment to ensure the normal operation of the equipment and the safety of the working environment of the personnel. In the event of a fire, the cover is first closed and the buckle is tightened so that the buckle is tightly pressed against the cover. At the same time, the controller receives feedback from the smoke sensor that the target gas concentration inside the cabin exceeds the threshold. The controller controls the action of the rotating shaft 610 to reduce the inclination angle of the grid plate 620 until the grid plate 620 is in a closed state, and the first window unit and the second window unit are closed at the same time to prevent the spread of smoke.
[0051] Optionally, when the hatch is used in a cargo hold, different cargoes have different requirements for the ventilation conditions of the storage environment. The controller can control the inclination angle of the grille 620 and adjust the ventilation volume in the cargo hold based on environmental information such as ventilation volume, temperature, humidity, etc. in the hold collected by the sensing device, so that the environmental information in the cargo hold (harmful gas concentration, temperature, humidity, etc.) meets the storage needs of different cargoes.
