Description

Technical Field

[0001] This invention relates to the technical field of ship compartments, and in particular to a ship compartment sealing device. Background Technology

[0002] Ship compartments are an important structural design feature. They are created by using robust transverse bulkheads to divide the ship's interior along its length into several independent, non-communicating compartments. The core principle is "watertightness," meaning the bulkheads must effectively prevent water penetration. When a ship encounters an accident such as running aground or a collision that causes the hull to rupture, seawater will only flood into the damaged compartment or a few others, while the remaining compartments remain watertight. This ensures the ship retains some buoyancy and doesn't sink immediately, giving the crew valuable time to save themselves or await rescue.

[0003] When a ship encounters a collision and leaks water, existing vessels utilize compartments to provide buoyancy and ensure the ship retains some buoyancy, allowing crew members to await rescue within these compartments. However, existing compartments are sealed using large, airtight doors. When water enters the ship, these doors are difficult to open under water pressure. Even if they are opened and water flows into the compartment, the doors are difficult to close again, making it difficult for personnel to enter and take refuge inside, or to retrieve items urgently needed within the compartment. Summary of the Invention

[0004] To at least partially solve the aforementioned problems existing in the prior art, the present invention provides a ship compartment sealing device.

[0005] A ship compartment sealing device includes a hatch, a slot, and a water-blocking component. The slot is formed on and passes through the hatch. The water-blocking component is disposed on the hatch at a position corresponding to the slot. The water-blocking component is configured to seal or open the slot when the water level does not exceed the slot or exceeds the slot.

[0006] The water-cutting component includes multiple water-cutting plates, which are located on the same plane perpendicular to the through direction of the slot. The multiple water-cutting plates are configured to converge and close towards the center of the plane or disperse and open away from the center of the plane simultaneously, so as to seal the slot when closed and open the slot when open.

[0007] Optionally, the water-cutting assembly further includes an installation structure for mounting the plurality of water-cutting plates on the hatch;

[0008] The installation structure includes a fixed disk and a rotating disk. The fixed disk and the rotating disk have first connecting openings corresponding to the slots. Multiple water-cutting plates are sandwiched between the fixed disk and the rotating disk. The fixed disk has multiple guide grooves, and guide blocks are correspondingly provided on each of the multiple water-cutting plates. The guide blocks slide in conjunction with the guide grooves to achieve the convergence and closure, and dispersion and opening of the multiple water-cutting plates during the sliding contact process. The rotating disk has multiple sliding grooves, and sliders are correspondingly provided on each of the multiple water-cutting plates. The sliders slide within the sliding grooves. The sliding grooves are configured such that when the rotating disk rotates, the sliders slide along the sliding grooves, thereby causing the water-cutting plates to move along the guide grooves.

[0009] Optionally, the plurality of water-cutting plates are arranged in a circular pattern, and correspondingly, the plurality of guide grooves and the plurality of sliding grooves are also arranged along the circumference of the fixed disk and the rotating disk, respectively.

[0010] The chute extends radially along the rotating disk. When the multiple water-blocking plates converge and close, the extension line of the chute has the same angle as the two side lines of the water-blocking plate near the center of the plane, and the extension line of the chute is perpendicular to the extension line of the guide groove.

[0011] Optionally, the fixed disk is provided with a plurality of supporting connecting rods along the circumference, and the rotating disk is provided with a plurality of rotating grooves along the circumference. The rotating grooves extend along the circumference of the rotating disk, and the supporting connecting rods slide through the rotating grooves.

[0012] Optionally, the water interception assembly further includes a transmission structure for driving the rotating disk to rotate about its own axis;

[0013] The transmission structure includes a first turntable handle, a first bevel gear, a second bevel gear, a worm, and a worm wheel.

The second bevel gear is coaxially and fixedly connected to the worm and meshes with the first bevel gear. The worm wheel is fixedly mounted on the turntable and meshes with the worm. The worm wheel extends circumferentially along the turntable.

[0014] Optionally, there are two first turntable handles, with the two first turntable handles located inside and outside the compartment, respectively;

[0015] The two first turntable handles are coaxially connected by the same rotating shaft, which passes through the first bevel gear.

[0016] Optionally, the sealing device further includes a sealing assembly disposed on the hatch, the sealing assembly being disposed corresponding to the slot;

The third rotary handle is rotatably configured, and the linkage structure is used to connect the third rotary handle and the pin. When the third rotary handle is rotated, the pin is moved by the linkage structure, causing the pin to extend out of the hatch and lie horizontally between the hatch and the bulkhead door frame and abut against the bulkhead door frame to form a mechanical stop with the bulkhead door frame.

[0023] Optionally, the third turntable handle is rotatably mounted on the hatch via a rotating shaft;

[0024] The linkage structure includes a first linkage and a second linkage. The first linkage is fixedly mounted on the rotating shaft.

[0025] In a ship compartment sealing device of the present invention, a slot is opened on the hatch and a water-blocking component is installed at the slot. When the water level does not exceed the slot, the water-blocking component can normally control the opening and closing of the slot. When the water level exceeds the slot, the water-blocking component can still control the opening and closing of the slot under the action of water pressure, so that crew members or materials can pass through the slot to pass through the ship compartment, so as to realize the refuge of crew members and the retrieval of materials.

[0032] The following reference Figures 1-6 This invention describes a ship compartment sealing device.

[0033] refer to Figures 1-6 This invention provides a ship compartment sealing device, including a hatch 2, a slot 21, and a water-blocking component. The slot 21 is formed in and extends through the hatch 2, connecting the inside and outside of the ship's compartment to allow crew or cargo to pass through. The water-blocking component is positioned on the hatch 2 corresponding to the slot 21. The water-blocking component is configured to seal or open the slot 21 whether the inlet water level has passed or not.

[0034] When water enters the ship, the hatch 2 cannot be opened or closed due to water pressure. By setting up a water-blocking component and a channel 21, when the water level does not exceed the channel 21, the water-blocking component can normally control the opening and closing of the channel 21. When the water level exceeds the channel 21, the water-blocking component can still control the opening and closing of the channel 21 under water pressure, thereby allowing crew members or supplies to pass through the channel 21 through the ship's compartments, enabling crew members to take refuge and supplies to be retrieved.

[0035] In some embodiments of the present invention, the water-blocking assembly includes a plurality of water-blocking plates 43, which are located on the same plane perpendicular to the through direction of the slot 21. The plurality of water-blocking plates 43 are configured to converge and close towards the center of the plane or disperse and open away from the center of the plane simultaneously, so as to seal the slot 21 when closed and open the slot 21 when open. In one specific example, three water-blocking plates 43 are provided.

[0036] Multiple water-blocking plates 43 are brought together and closed towards the center along a plane perpendicular to the groove opening 21. When the water level exceeds the groove opening 21, the shearing force of the water-blocking plates 43 can be used to shear the water flow, thereby facilitating the sealing of the groove opening 21 by the water-blocking plates 43.

[0037] In some embodiments of the present invention, the water-blocking assembly further includes an installation structure for mounting a plurality of the above-described water-blocking plates 43 onto the hatch 2.

[0038] In some embodiments of the present invention, the mounting structure includes a fixed disk 41 and a rotating disk 42, with first connecting openings 417 on both the fixed disk 41 and the rotating disk 42 corresponding to the slot 21. Multiple water-cutting plates 43 are sandwiched between the fixed disk 41 and the rotating disk 42. The fixed disk 41 has multiple guide grooves 413, and each of the multiple water-cutting plates 43 is provided with a corresponding guide block 44. The guide block 44 slides into the guide grooves 413 to achieve the convergence and closure, and the dispersion and opening of the multiple water-cutting plates 43 during the sliding engagement. The rotating disk 42 has multiple sliding grooves 414, and each of the multiple water-cutting plates 43 is provided with a corresponding slider 45, which slides within the sliding grooves 414. The multiple sliding grooves 414 are configured such that when the rotating disk 42 rotates, the sliders 45 slide along the sliding grooves 414, thereby causing the water-cutting plates 43 to move along the guide grooves 413. In a specific example, the guide block 44 is square-shaped, and the slider 45 is cylindrical.

[0039] When multiple water-blocking plates 43 need to be brought together to close or dispersed to open, the rotating disk 42 is rotated in the forward or reverse direction. The rotation of the rotating disk 42 causes the slider 45 to slide along the slide groove 414. The sliding of the slider 45 in turn causes the guide block 44 on the water-blocking plate 43 to move along the guide groove 413, thereby realizing the gathering and closing or dispersion and opening of multiple water-blocking plates 43. The whole structure is relatively simple and easy to operate.

[0040] In some embodiments of the present invention, a plurality of water-blocking plates 43 are arranged circumferentially. Correspondingly, a plurality of guide grooves 413 and a plurality of sliding grooves 414 are also arranged circumferentially along the fixed disk 41 and the rotating disk 42, respectively. The sliding grooves 414 extend radially along the rotating disk 42. When the plurality of water-blocking plates 43 are brought together and closed, the extension line of the sliding groove 414 has the same angle as the two edges of the water-blocking plate 43 near the center of the aforementioned plane, and the extension line of the sliding groove 414 is perpendicular to the extension line of the guide groove 413.

[0041] By maintaining the same angle between the two sides of the intercepting plate 43 near the center and the radial line of the extension line of the chute 414, when multiple intercepting plates 43 converge towards the center simultaneously, the inner ends of each intercepting plate 43 are arranged in a regular radial pattern at the center of the plane. The corresponding edges of adjacent intercepting plates 43 can fit parallel to each other, thus forming a continuous and uniform overlapping interface at the closing endpoint, eliminating central gaps and gaps between plates, and improving water interception and sealing performance. In addition, the chute 414 is arranged radially and perpendicular to the guide groove 413, so that each intercepting plate 43 has a unique and definite trajectory, and there will be no movement differences or misalignment among multiple intercepting plates 43, avoiding jamming or collision during the convergence process.

[0042] In some embodiments of the present invention, a supporting connecting rod 46 is provided on the fixed disk 41, and a corresponding rotating groove 415 is provided on the rotating disk 42. The rotating groove 415 extends circumferentially along the rotating disk 42, and the supporting connecting rod 46 slides through the rotating groove 415. By providing the supporting connecting rod 46, support is provided for the rotation of the rotating disk 42, further improving the stable connection between the rotating disk 42 and the fixed plate.

[0043] In some embodiments of the present invention, multiple support rods 46 are provided along the circumference of the fixed disk 41. Correspondingly, multiple rotating slots 415 are also provided along the circumference of the rotating disk 42.

[0044] In some embodiments of the present invention, the water interception assembly further includes a transmission structure for driving the rotating disk 42 to rotate about its own axis.

[0045] In some embodiments of the present invention, the transmission structure includes a first turntable handle 416, a first bevel gear 410, a second bevel gear 411, a worm 47, and a worm wheel 48. The first turntable handle 416 and the worm 47 are both rotatably mounted along their own axes. The first turntable handle 416 is coaxially and fixedly connected to the first bevel gear 410, and the second bevel gear 411 is coaxially and fixedly connected to the worm 47, meshing with the first bevel gear 410. The worm wheel 48 is fixedly mounted on a rotating disk 42 and meshes with the worm 47. The worm wheel 48 extends circumferentially along the rotating disk 42.

[0046] When the rotating disk 42 needs to rotate, the first turntable handle 416 is rotated, which drives the first bevel gear 410 to rotate synchronously. The rotation of the first bevel gear 410 drives the second bevel gear 411 to rotate synchronously, and the rotation of the second bevel gear 411 drives the worm gear 47 to rotate synchronously. The rotation of the worm gear 47 drives the worm wheel 48 to rotate, which in turn drives the rotating disk 42 to rotate around its own axis. By rotating the first turntable handle 416 in the forward or reverse direction, the rotating disk 42 can be rotated in the forward or reverse direction, thereby causing the multiple water-blocking plates 43 to close together or open separately.

[0047] In some embodiments of the present invention, an installation cavity is formed inside the hatch 2 at a position corresponding to the slot 21, and the water-blocking component is disposed within the installation cavity. In this case, the fixing plate is fixedly disposed on the inner wall of the hatch 2, and the first turntable handle 416 and the worm gear 47 are both rotatably disposed on the hatch 2. By placing the water-blocking component inside the hatch 2, the volume of the hatch 2 itself is fully utilized, reducing the overall space occupied by the water-blocking component and the sealing device. Furthermore, it provides protection for the water-blocking component.

[0048] Of course, the water-blocking components can also be directly installed on the outer wall of hatch 2.

[0049] In some embodiments of the present invention, the first turntable handle 416 is rotatably mounted on the hatch 2 via a rotating shaft 49, and the first bevel gear 410 is coaxially fixed on the rotating shaft 49, thereby realizing the transmission connection between the first turntable handle 416 and the first bevel gear 410 through the rotating shaft 49.

[0050] In some embodiments of the present invention, two first turntable handles 416 are provided, with the two first turntable handles 416 located inside and outside the compartment, respectively. The two first turntable handles 416 are coaxially connected via the same rotating shaft 49. The rotating shaft 49 passes through the first bevel gear 410. By providing first turntable handles 416 inside and outside the compartment, the operation of the water interception component can be controlled both inside and outside the compartment, thereby controlling the sealing and opening of the slot 21.

[0051] In some embodiments of the present invention, two support seats 412 are provided inside the mounting cavity, and the two ends of the worm gear 47 are respectively rotatably mounted on the support seats 412. By providing support seats 412, the rotation of the worm gear 47 is made more stable.

[0052] In some embodiments of the present invention, the slot 21 is located near the top of the hatch 2. When the ship takes on water, it can delay the time it takes for the water level to pass over the slot 21.

[0053] In some embodiments of the present invention, the sealing device further includes a sealing assembly disposed on the hatch 2, which is also disposed corresponding to the slot 21. The sealing assembly is used to further seal the slot 21.

[0054] In some embodiments of the present invention, the sealing assembly includes a sealing plate 32, a rack 35, a second rotary handle 38, and a drive gear 34. The sealing plate 32 is slidably disposed, and the rack 35 is fixedly disposed on the sealing plate 32 and extends along the sliding direction of the sealing plate 32. The second rotary handle 38 is rotatably disposed along its own axis, and the drive gear 34 is coaxially and fixedly connected to the second rotary handle 38. The drive gear 34 meshes with the rack 35.

[0055] When further sealing of the slot 21 is required, rotating the second turntable handle 38 causes the drive gear 34 to rotate synchronously, which in turn causes the rack 35 and the sealing plate 32 to slide together. When the sealing plate 32 slides to the position covering the slot 21, further sealing of the slot 21 is achieved. Similarly, rotating the second turntable handle 38 in the opposite direction, causing the sealing plate 32 to slide away from the slot 21, allows the slot 21 to be opened.

[0056] In some embodiments of the present invention, the sealing device further includes a mounting box 31, which is fixedly mounted on the hatch 2. The sealing assembly is disposed inside the mounting box 31. The mounting box 31 has a second communication opening 37 corresponding to the slot 21. In this case, the sealing plate 32 is slidably disposed on the inner wall of the mounting box 31. In a specific example, the mounting box 31 is disposed inside the compartment. By placing the sealing assembly inside the mounting box 31, the sealing assembly is protected.

[0057] Of course, the sealing components can also be directly installed on the outer wall of hatch 2.

[0058] In some embodiments of the present invention, the second turntable handle 38 is rotatably mounted on the mounting box 31 via a connecting shaft 33, and the drive gear 34 is coaxially fixed on the connecting shaft 33. The connecting shaft 33 enables the transmission connection between the second turntable handle 38 and the drive gear 34.

[0059] In some embodiments of the present invention, two second rotary handles 38 are provided, with the two second rotary handles 38 located inside and outside the compartment, respectively. The two second rotary handles 38 are coaxially connected by the same connecting shaft 33. The connecting shaft 33 passes through the drive gear 34. By providing second rotary handles 38 inside and outside the compartment, the operation of the sealing assembly can be controlled both inside and outside the compartment, thereby controlling the secondary sealing and opening of the slot 21.

[0060] In some embodiments of the present invention, the sealing assembly further includes a guide rod 36, on which the sealing plate 32 slidably passes. By providing the guide rod 36, the sliding of the sealing plate 32 is guided and limited, making the sliding of the sealing plate 32 more stable. In a specific example, the guide rod 36 is vertically arranged, and correspondingly, the sealing plate 32 slides vertically on the guide rod 36.

[0061] In some embodiments of the present invention, the sealing device further includes a locking assembly, which is also disposed on the hatch 2 and located inside the compartment, for locking the hatch 2 to achieve sealing of the compartment.

[0062] In some embodiments of the present invention, the locking assembly includes a third rotary handle 51, a connecting rod structure, and a pin 54. The third rotary handle 51 is rotatably mounted. The connecting rod structure connects the third rotary handle 51 and the pin 54, so that when the third rotary handle 51 is rotated, the pin 54 is moved through the connecting rod structure, causing the pin 54 to extend out of the hatch 2 and be positioned horizontally between the hatch 2 and the bulkhead door frame 1 and abut against the bulkhead door frame 1, thereby forming a mechanical stop with the bulkhead door frame 1 and thus locking and fixing the hatch 2.

[0063] In some embodiments of the present invention, the latch 54 is a U-shaped rod structure, and the two free ends of the U-shaped rod structure can extend out of the hatch 2 and be placed horizontally between the hatch 2 and the compartment door frame 1 and abut against the compartment door frame 1.

[0064] In some embodiments of the present invention, a wedge-shaped surface is provided on the side of the latch 54 extending out of the hatch 2 near the bulkhead frame 1. On the one hand, the wedge-shaped surface acts as a guide when the latch 54 extends out of the hatch 2, making it easier for the latch 54 to be positioned horizontally between the hatch 2 and the bulkhead frame 1. On the other hand, the wedge-shaped surface decomposes the extension movement of the latch 54 in the direction perpendicular to the surface of the hatch 2 into a component force toward the bulkhead frame 1, thereby driving the entire hatch 2 to move toward the bulkhead frame 1, thus achieving a smooth transition from gap elimination to sealing between the hatch 2 and the bulkhead frame 1.

[0065] In some embodiments of the present invention, a third rotary handle 51 is rotatably mounted on the hatch 2 via a rotating shaft. Two third rotary handles 51 are provided, located inside and outside the compartment respectively. The two third rotary handles 51 are coaxially connected via the same rotating shaft. By providing third rotary handles 51 inside and outside the compartment respectively, the opening and closing of the hatch 2 can be controlled from both inside and outside the compartment.

[0066] In some embodiments of the present invention, the linkage structure includes a first linkage 52 and a second linkage 53. The first linkage 52 is fixedly mounted on the rotating shaft. One end of the second linkage 53 is hinged to the first linkage 52, and the other end is hinged to the pin 54. The locking assembly also includes a guide seat 55, on which the pin 54 is slidably mounted. By rotating the third turntable handle 51, the rotating shaft is rotated, thereby causing the first linkage 52 to rotate synchronously. The rotation of the first linkage 52 causes the second linkage 53 and the pin 54 to move, thereby enabling the pin 54 to extend out of the hatch 2 and be positioned horizontally between the hatch 2 and the bulkhead door frame 1, and to abut against the bulkhead door frame 1, thus forming a mechanical stop with the bulkhead door frame 1. By providing the guide seat 55, the movement of the pin 54 is limited, so that the pin 54 can only move in a specific direction.

[0067] In one specific example, two U-shaped rod-shaped pins 54 are provided, located on the sides of the hatch 2 near the top and bottom ends, respectively. Both free ends of the pins 54 are vertically positioned and slidably pass through the guide seats 55, allowing the pins 54 to slide only vertically. Two second connecting rods 53 are provided, hinged to both ends of the first connecting rod 52. The ends of the second connecting rods 53 furthest from the first connecting rod 52 are hinged to the crossbar of the pins 54.

[0068] In some embodiments of the present invention, the hatch 2 is hinged to the compartment door frame 1. A sealing layer is provided on the contact surface between the hatch 2 and the compartment door frame 1. Specifically, the hatch 2 and the compartment door frame 1 can be hinged together.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
