Description

Technical Field

[0001] This invention belongs to the field of sealing technology, and more specifically, relates to a leak-proof sealing structure for ship cabins and a ship cabin. Background Technology

[0002] Ship compartments are the core spaces on a vessel that carry cargo, equipment, and various media. The sealing performance of these compartments directly affects the safety of navigation, the integrity of cargo, and the personal safety of crew members. Among these, the joints of the compartment wall panels (such as steel plate splicing joints and the joints between compartment doors and door frames) are the most common sites for leakage.

[0003] Currently, the sealing structures installed at the joints of ship cabin bulkheads mostly use a single sealant filling method or a simple sealing gasket bonding method. During the ship's voyage, it is subjected to complex conditions such as long-term impact of sea waves and ship hull vibration. The reliability of the sealing structure at the joints is poor, and a single sealing structure is difficult to withstand long-term ship hull vibration. After a period of use, the seal is prone to failure, and the risk of leakage is prominent, especially in cargo holds and ballast tanks. Leakage can lead to moisture damage to cargo, accelerated corrosion of the hull structure, and in severe cases, affect the stability of the ship. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a leak-proof sealing structure for ship cabins and a ship cabin itself. This solves the problem mentioned in the background that existing ship cabin wall panel joints often use a single sealant or gasket, which is prone to sealing failure and leakage under complex working conditions such as wave impact and vibration due to its poor reliability. This leads to cargo damage, accelerated hull corrosion, and endangers the stability of the ship.

[0005] To achieve the above objectives, the present invention provides a leak-proof sealing structure for ship compartments, used at the joint formed by the butt joint of two adjacent wall panels in a ship compartment, the leak-proof sealing structure comprising: The first sealing assembly includes a first sealing gasket and two elastic pressing blocks. A joint groove is formed on the outer side of the wall panel at both sides of the joint. The first sealing gasket is disposed inside the joint groove. The two elastic pressing blocks are respectively disposed on both sides of the first sealing gasket and are respectively pressed against the inner sides of the joint groove. The second sealing component is a water-absorbing and expanding sealing component. The second sealing component is disposed inside the joint groove and on the side of the first sealing component away from the bottom of the joint groove.

[0006] Preferably, the second sealing assembly includes: The second sealing gasket is a water-absorbing and expanding sealing gasket. The pressure strip consists of a first sealing gasket, a second sealing gasket, and the pressure strip stacked sequentially, with the pressure strip being detachably connected to both sides of the inside of the joint groove.

[0007] Preferably, a sealing adhesive layer is provided between the first sealing gasket and the bottom of the joint groove, between the second sealing gasket and the first sealing gasket, and between the pressure strip and the second sealing gasket.

[0008] Preferably, the inner sides of the joint groove are provided with mounting grooves, the outer side of the wall panel is provided with threaded holes communicating with the mounting grooves, the two sides of the pressure strip are respectively embedded in the mounting grooves on both sides, and bolts are threadedly connected in the threaded holes, with one end of the bolt abutting against the pressure strip.

[0009] Preferably, the ship compartment leak-proof sealing structure further includes: A leakage warning component, wherein the detection end of the leakage warning component is disposed between the first sealing component and the second sealing component.

[0010] Preferably, the leakage early warning component includes Multiple leakage sensors are distributed between the first sealing assembly and the second sealing assembly; An early warning controller is electrically connected to a plurality of the leakage sensors and is mounted on the control panel of the vessel.

[0011] Preferably, the ship compartment leak-proof sealing structure further includes: A protective cover plate covers the opening of the joint groove, and a sealing adhesive layer is provided between the protective cover plate and the wall panel.

[0012] Preferably, the surface of the first sealing gasket is provided with a plurality of annular sealing protrusions to increase the contact area with the sealing adhesive layer.

[0013] Preferably, the elastic clamping block is trapezoidal.

[0014] A ship compartment comprising: Multiple leak-proof sealing structures for ship compartments are installed at various joint locations within the ship compartments.

[0015] This invention provides a leak-proof sealing structure for ship cabins and a ship cabin. Its advantages are as follows: the first sealing component of the leak-proof sealing structure includes a first sealing gasket and two elastic clamping blocks. The two elastic clamping blocks are respectively disposed on both sides of the first sealing gasket and are respectively pressed against the inner sides of the joint groove. The first sealing component is adapted to the vibration conditions of the ship hull. By utilizing the elastic deformation of the elastic clamping blocks, a uniform clamping force can always be applied to the first sealing gasket to automatically compensate for the joint displacement caused by the vibration of the hull, thereby effectively avoiding the leakage problem caused by the gap generated by vibration in traditional sealing structures.

[0016] The second sealing component of this leak-proof sealing structure is a water-absorbing and expanding sealing component. The second sealing component is located on the bottom side of the groove away from the joint groove of the first sealing component. The second sealing component can actively fill the sealing gap. Compared with traditional ordinary sealing gaskets, in the early stage of leakage, the second sealing component will undergo slight volume expansion when it comes into contact with water, thereby automatically filling the tiny sealing gaps caused by hull vibration, realizing secondary blocking and sealing of the leakage channel, and further improving the overall reliability of leak prevention.

[0017] This leak-proof sealing structure breaks through the traditional single sealing mode, adopting a layered protection of a first sealing component and a second sealing component. The first sealing component serves as the first line of defense, and the second sealing component serves as the second line of defense. During operation, the double sealing defense formed by the first and second sealing components, combined with elastic compression and expansion sealing, can effectively compensate for the joint displacement caused by hull vibration, block leakage channels, resist the leakage of seawater and internal media, greatly improve sealing reliability, and ensure stable compartment sealing performance.

[0022] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] like Figure 1 As shown, the present invention provides a leak-proof sealing structure for ship compartments, used at the joint 2 formed by the butt joint of two adjacent wall panels 1 in a ship compartment. The leak-proof sealing structure includes: The first sealing assembly includes a first sealing gasket 3 and two elastic pressing blocks 4. A joint groove 5 is formed on the outer side of the wall panel 1 and on both sides of the joint 2. The first sealing gasket 3 is disposed inside the joint groove 5, and the two elastic pressing blocks 4 are respectively disposed on both sides of the first sealing gasket 3 and are respectively pressed into the inner sides of the joint groove 5. The second sealing component is a water-absorbing and expanding sealing component. The second sealing component is located inside the joint groove 5 and is located on the side of the first sealing component away from the bottom of the joint groove 5.

[0024] Specifically, to address the problem that existing ship cabin wall panel joints often use a single sealant or gasket, which is prone to sealing failure and leakage under complex conditions such as wave impact and vibration, leading to cargo damage, accelerated hull corrosion, and endangering ship stability, this invention provides a leak-proof sealing structure for ship cabins. The joint groove 5 of this leak-proof sealing structure is U-shaped and is set along the length of the joint 2. Part of the joint groove 5 is located on one side of the joint 2, and the other part is located on the other side. The inner wall of the joint groove 5 is treated for rust removal and corrosion prevention, specifically sandblasting (Sa2.5 grade) and epoxy zinc-rich primer, to prevent seawater from corroding the inner wall of the joint groove 5 and affecting the sealing effect.

[0025] The first sealing component of this leak-proof sealing structure is located at the bottom of the joint groove 5, serving as the first line of defense. It includes a first sealing gasket 3 and two elastic clamping blocks 4. The first sealing gasket 3 is made of fluororubber material that is resistant to seawater corrosion and high and low temperatures, and is fitted to the bottom of the joint groove 5. The elastic clamping blocks 4 are made of silicone rubber and have good elastic reset performance. The first sealing component is adapted to the vibration conditions of the ship's hull. By utilizing the elastic deformation of the elastic clamping blocks 4, a uniform clamping force can always be applied to the first sealing gasket 3 to automatically compensate for the joint displacement caused by the vibration of the hull, thereby effectively avoiding the leakage problem caused by the gap generated by vibration in traditional sealing structures.

[0026] The second sealing component of this leak-proof sealing structure is a water-absorbing and expanding sealing component. The second sealing component is located on the side of the groove bottom away from the joint groove 5 of the first sealing component. The second sealing component can actively fill the sealing gap. Compared with traditional ordinary sealing gaskets, in the early stage of leakage, the second sealing component will undergo slight volume expansion when it comes into contact with water, thereby automatically filling the tiny sealing gaps caused by the vibration of the hull, realizing secondary blocking and sealing of the leakage channel, and further improving the overall reliability of leak prevention.

[0027] This leak-proof sealing structure breaks through the traditional single sealing mode, adopting a layered protection of a first sealing component and a second sealing component. The first sealing component serves as the first line of defense, and the second sealing component serves as the second line of defense. During operation, the double sealing defense formed by the first and second sealing components, combined with elastic compression and expansion sealing, can effectively compensate for the joint displacement caused by hull vibration, block leakage channels, resist the leakage of seawater and internal media, greatly improve sealing reliability, and ensure stable compartment sealing performance.

[0028] Preferably, the second sealing assembly includes: The second sealing gasket 6 is a water-absorbing and expanding sealing gasket. The pressure strip 7, the first sealing gasket 3, the second sealing gasket 6 and the pressure strip 7 are stacked in sequence, and the pressure strip 7 is detachably connected to the inside two sides of the joint groove 5.

[0029] Specifically, the second sealing component of the leak-proof sealing structure is located on the side of the first sealing component away from the bottom of the joint groove 5, and fits tightly with the first sealing component as a second sealing line. It includes a second sealing gasket 6 and a pressure strip 7. The second sealing gasket 6 is made of expandable rubber material, which can expand slightly when exposed to water to fill the sealing gap. The pressure strip 7 is a stainless steel pressure strip with a thickness of 3-5mm. The surface is polished and anti-corrosion treated. The length of the pressure strip 7 is the same as the length of the joint groove 5, which can apply uniform pressure to the second sealing gasket 6 and avoid uneven local pressure that could lead to sealing failure.

[0030] Preferably, a sealing layer 8 is provided between the first sealing gasket 3 and the bottom of the joint groove 5, between the second sealing gasket 6 and the first sealing gasket 3, and between the pressure strip 7 and the second sealing gasket 6.

[0031] Specifically, the sealant layer 8 uses a marine-grade sealant layer that is resistant to high temperatures, aging, and seawater corrosion. It has good adhesion, corrosion resistance, and aging resistance, and the curing time is no more than 24 hours, which facilitates rapid construction.

[0032] Preferably, the inner sides of the joint groove 5 are provided with mounting grooves, the outer side of the wall panel 1 is provided with threaded holes communicating with the mounting grooves, the two sides of the pressure strip 7 are respectively embedded in the mounting grooves on both sides, and the threaded holes are threaded with bolts 9, one end of the bolts 9 abutting against the pressure strip 7.

[0033] Specifically, a pressure strip 7 is provided on the side of the second sealing gasket 6 away from the first sealing gasket 3. The pressure strip 7 is connected to the wall panel 1 by a fastener. The fastener is made of corrosion-resistant stainless steel bolts. During maintenance and disassembly, the bolts 9 can be removed and the pressure strip 7 can be pulled out, which is convenient for maintenance, can significantly shorten the maintenance period, reduce maintenance costs, and reduce the impact on the normal operation of the ship.

[0034] Preferably, the ship's compartment leak-proof sealing structure further includes: A leakage warning component, wherein the detection end of the leakage warning component is located between the first sealing component and the second sealing component.

[0035] Specifically, to address the problem that existing leak-proof sealing structures lack leak warning functions, making it difficult to detect leaks in their early stages after the sealing structure fails, and often only being noticed when the leakage is large and causes significant damage, thus missing the best time for repair and increasing maintenance costs and navigation risks, this application provides a leak warning component between the first sealing component and the second sealing component. The leak warning component facilitates timely inspection and repair by personnel.

[0036] Preferably, the leakage early warning component includes Multiple leakage sensors 10 are distributed between the first sealing assembly and the second sealing assembly; The early warning controller is electrically connected to multiple leakage sensors 10 and is mounted on the ship's control panel.

[0037] Specifically, the leakage early warning component is embedded between the first sealing component and the second sealing component. It includes multiple leakage sensors, signal transmission lines, and an early warning controller. The leakage sensors are waterproof contact sensors with a protection level of not less than IP67. There are no fewer than three of them, which are evenly distributed around the periphery of the joint groove 5. They can adapt to the humid and corrosive environment of the ship's cabin and have a service life of not less than 5 years. The leakage sensor 10 is connected to the early warning controller through the signal transmission line. The early warning controller is installed on the control panel outside the cabin. The early warning controller is equipped with an alarm module and a signal storage module. When the leakage sensor 10 detects the leakage medium, it can quickly transmit the signal to the early warning controller. The early warning controller triggers the alarm module to issue an audible and visual alarm and records the leakage time and location. This facilitates timely investigation and maintenance by the staff, overcoming the shortcomings of the existing technology of "no early warning, late detection, and inability to trace the source" and improving maintenance efficiency.

[0038] Preferably, the ship's compartment leak-proof sealing structure further includes: A protective cover plate 11 covers the opening of the joint groove 5, and a sealing layer 8 is provided between the protective cover plate 11 and the wall panel 1.

[0039] Specifically, the protective cover is made of steel plate with the same material as the cabin wall panel. The protective cover and the wall panel are sealed with a sealing adhesive layer to prevent dust and debris from entering the joint groove and damaging the first sealing component, the second sealing component and the leakage warning component.

[0040] like Figure 2 As shown, preferably, the surface of the first sealing gasket 3 is provided with a plurality of annular sealing protrusions 12 to increase the contact area with the sealing adhesive layer 8.

[0041] Specifically, the thickness of the first sealing gasket 3 is 8-12mm, the width of the first sealing gasket 3 is adapted to the width of the joint groove, and the surface of the first sealing gasket 3 is provided with several annular sealing protrusions 12. The annular sealing protrusions 12 are tightly attached to the sealing adhesive layer 8, which can increase the contact area between the first sealing gasket 3 and the sealing adhesive layer 8 and improve the main sealing effect.

[0042] Preferably, the elastic clamping block 4 is trapezoidal.

[0043] Specifically, the cross-section of the elastic clamping block 4 is trapezoidal. The trapezoidal elastic clamping block 4 can provide a more ideal elastic recovery force, and can maintain effective contact through elastic deformation, thus expanding the scope of application and reducing the requirements for processing precision. The length of the elastic clamping block 4 is adapted to the length of the first sealing gasket 3. The two elastic clamping blocks 4 are evenly distributed on both sides of the first sealing gasket 3. The compression of the elastic clamping block 4 is controlled at 20%-30%, which can ensure sufficient clamping force and avoid excessive compression that leads to elastic failure. The design is more targeted.

[0044] A ship compartment comprising: Multiple leak-proof sealing structures for ship compartments are installed at multiple joints 2 of the ship compartments.

[0045] Specifically, to overcome the shortcomings of existing ship compartment sealing structures such as poor sealing reliability, lack of leakage warning, and inconvenient maintenance, a ship compartment anti-leakage sealing structure is provided. It is installed at the joint 2 position of the ship compartment, improves sealing reliability through a double sealing design, adds a leakage warning component to realize real-time monitoring, optimizes the structural design to facilitate local maintenance, reduces leakage risk and maintenance costs, and ensures the safety of ship navigation.

[0046] The thickness and width of the first sealing gasket 3 and the second sealing gasket 6, as well as the distribution spacing of the elastic compression block 4 and the leakage sensor 10, can be flexibly adjusted according to the joint size of different types of ship compartments (cargo hold, engine room, ballast tank) to adapt to different working conditions. At the same time, the materials of each component (seawater resistant, high and low temperature resistant, aging resistant) are universally selected, the manufacturing cost is low, and it is easy to mass-produce and promote application, which is different from the existing special sealing structures that are highly targeted but have poor adaptability.

[0047] In summary, when the anti-leakage sealing structure of the ship compartment of this application is implemented in the joint 2 of the ship compartment, the anti-leakage sealing structure breaks through the traditional single sealing mode. It adopts a first sealing component and a second sealing component to form a double sealing defense line to resist the leakage of seawater and the medium inside the compartment. The elastic compression block 4 of the first sealing component utilizes the elastic deformation performance to always apply a uniform compression force to the first sealing gasket 3, so as to automatically compensate for the joint displacement caused by the vibration of the hull and block the leakage channel, thereby effectively avoiding the leakage problem caused by the gap generated by vibration in the traditional sealing structure. The second sealing component can actively fill the sealing gap. Compared with the traditional ordinary sealing gasket, in the early stage of leakage, the second sealing gasket 6 of the second sealing component will undergo slight volume expansion when it comes into contact with water, thereby automatically filling the small sealing gap generated by the vibration of the hull, realizing secondary blocking and sealing of the leakage channel, and further improving the overall reliability of anti-leakage.

[0048] When the leak-proof sealing structure experiences partial failure and leakage, the leaking medium will first penetrate between the first sealing component and the second sealing component. At this time, the leakage sensor 10 detects the leakage signal and transmits the signal to the early warning controller through the signal transmission line. The early warning controller triggers an audible and visual alarm and records the leakage-related information. Based on the early warning prompts, the staff can quickly locate the leakage location. The repair can be completed simply by removing the protective cover plate 11 and pressure strip 7 at the corresponding location and replacing the seal at the joint 2. There is no need to remove the entire leak-proof sealing structure of the ship's cabin, making the repair convenient and efficient.

[0049] This leak-proof sealing structure addresses the core defects of existing technologies, namely "unreliable sealing, lack of early warning, difficult maintenance, and short lifespan." Through synergistic design, it not only ensures sealing performance but also takes into account the actual operating conditions required for ship navigation, demonstrating clear technical improvement and practical value.

[0050] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
