Description

Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to a ship-used foaming leak-stopping device. Background Art

[0002] In the complex and ever-changing environment of shipping and maritime operations, ships often face threats from multiple sources, including natural factors such as collisions, groundings, and storms, as well as unnatural factors such as hull corrosion, human error, and even unforeseen scenarios like war. These factors can cause damage to the hull and flooding, seriously compromising the ship's structural integrity and navigation safety. In extreme cases, they can lead to a loss of buoyancy, resulting in a shipwreck and significant risk of casualties and property damage.

[0003] Traditional methods for plugging hull damage, such as wooden wedges, plugging plates, and plugging boxes, are effective for small breaches to a certain extent, but their limitations become apparent when dealing with medium- to large-scale breaches. Specifically, wooden plugging devices like wooden wedges and plugging plates are prone to falling apart when impacted by strong currents, significantly reducing their effectiveness. Therefore, the search for more efficient and reliable marine plugging devices has become a pressing issue for the industry.

[0004] Against this backdrop, foaming leak-proofing technology, with its rapid and effective plugging capabilities, has gradually become a hot topic in the marine leak-proofing field. This technology involves injecting a foaming material to quickly form a solid foam layer at the breach, effectively preventing water intrusion. However, existing foaming leak-proofing devices still need improvement in positioning stability, adaptability to large breaches, and ease of operation. Utility Model Content

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] Figure 1 This is a schematic diagram of the overall structure of a marine foaming plugging device according to one embodiment of the present invention. Figure 2 This is a front structural diagram of a marine foaming plugging device according to one embodiment of the present invention. Figure 1-2 As shown, according to one embodiment of the present invention, a marine foaming plugging device comprises: a foamer 1, a one-way valve 2, an extension rod 3, and a guide rod 5 connected in sequence;

[0045] The extension rod 3 is externally connected to an adjustable triangular bracket 4 for fixing the position of the extension rod 3;

[0046] The guide rod 5 is a hollow structure with holes arranged around it, and the outside of the guide rod 5 is connected to the air bag 6;

[0047] The foaming material arranged in the foamer 1 passes through the one-way valve 2, the extension rod 3, and the guide rod 5 in sequence and then fills into the air bag 6.

[0048] In this embodiment, a marine foaming leak-plugging device comprises a foamer 1, a one-way valve 2, an extension rod 3, and a guide rod 5, all connected in sequence. These components work together to achieve the leak-plugging function. The foamer 1, as the core component of the entire device, is responsible for storing and releasing the foaming material. This foaming material is specially treated to rapidly expand to form a solid foam layer, effectively plugging the leak. A one-way valve 2 is fixedly attached to the top of the foamer 1. The design of the one-way valve 2 ensures that the foaming material can only flow in one direction: from the foamer 1 to subsequent components, preventing backflow and leakage of the foaming material. The other side of the one-way valve 2 is connected to the extension rod 3. The extension rod 3 not only connects and transfers the foaming material but also connects to an adjustable triangular bracket 4 via its external guide thread. The adjustable triangular bracket 4 allows for flexible fixing and adjustment of the position of the extension rod 3 according to actual needs, ensuring that the entire device can stably act on the leak during the leak-plugging process. The other end of the extension rod 3 is connected to the guide rod 5. Guide rod 5 is also hollow and riddled with holes. These holes allow the foaming material to be evenly distributed around the guide rod as it passes through it, ultimately filling the airbag 6, which is securely connected to it. As the final output component of the entire device, airbag 6 is made of a soft, elastic material. As the foaming material fills airbag 6, it expands and fits snugly over the leak. Together, the airbag 6 and the foaming material form a solid barrier, effectively preventing liquid leakage.

[0049] The marine foaming leak-plugging device of the utility model realizes rapid, stable and effective plugging of leak points by sequentially connecting a foamer, a one-way valve, an extension rod and a hollow guide rod with holes, in combination with an adjustable triangular bracket fixation and air bag expansion, thereby forming a solid foam barrier to prevent liquid leakage.

[0050] Figure 3 This is a front cross-sectional structural diagram of a marine foaming plugging device according to one embodiment of the present invention. Figure 3 As shown, according to one embodiment of the present invention, the foamer 1 includes: an outer tube 11, a switch button 12, a central sleeve 13, and a base 14;

[0051] The switch button 12 is arranged on the outer wall of the outer tube 11, the central sleeve 13 is arranged inside the outer tube 11, and the two ends of the outer tube 11 are respectively connected to the base 14 and the one-way valve 2;

[0052] The switch button 12 controls the foaming material in the foamer 1 to enter the one-way valve 2 through the central sleeve 13 .

[0053] In this embodiment, the foamer 1 is a key component of the marine foaming plugging device, with a sophisticated structure and clear functions. The foamer 1 consists of an outer tube 11, a switch button 12, a central sleeve 13 and a base 14, and each part works closely together to achieve the controlled release of the foaming material. The outer tube 11 serves as the main structure, and the switch button 12 is cleverly set on its outer tube wall to facilitate the operator to control the foaming process. The central sleeve 13 is installed inside as a channel for the flow of foaming material, ensuring that the material can be output in an orderly and stable manner. The bottom of the outer tube 11 is fixed to the base 14 by a threaded connection. This design is not only stable and reliable, but also easy to disassemble and maintain. The top of the outer tube 11 is directly connected to the one-way valve 2, forming a complete foaming material delivery path. When the operator presses the switch button 12, the foaming material in the central sleeve 13 will be subjected to pressure and pass through the one-way valve 2 along the established path to enter the subsequent components of the plugging device.

[0054] The foamer of the utility model is exquisitely designed. Through the close cooperation of the outer tube, the switch button, the central shaft sleeve and the base, the controlled release of the foaming material is achieved, ensuring the orderly and stable output of the material. Through the direct connection with the one-way valve, a complete foaming material delivery path is formed, which effectively improves the operating convenience and plugging efficiency of the marine foaming plugging device.

[0055] Figure 4 This is a front structural diagram of a one-way valve according to an embodiment of the present invention. Figure 5 This is a front cross-sectional structural diagram of a one-way valve according to an embodiment of the present invention. Figure 4-5 As shown, according to one embodiment of the present invention, the one-way valve 2 includes: a valve body 21, a valve core 22, a spring 23, and an O-ring 24;

[0056] The two ends of the valve body 21 are respectively connected to the foamer 1 and the extension rod 3; the valve core 22 and the spring 23 are arranged inside the valve body 21; one end of the spring 23 is connected to the valve core 22, and the valve core 22 is pressed on the inner surface of the valve body 21 close to the foamer 1 under the action of the spring 23. An O-ring 24 is provided at the connection between the valve core 22 and the valve body 21.

[0057] Preferably, the ports at both ends of the valve body 21 are milled with threads, and the valve body 21 is screwed to the foamer 1 and the extension rod 3 respectively;

[0058] Preferably, the O-ring 24 is made of rubber material.

[0059] In this embodiment, the one-way valve 2 is composed of key components such as a valve body 21, a valve core 22, a spring 23 and an O-ring 24. The valve body 21 serves as the main structure of the one-way valve. The ports at both ends are precisely milled to form a standard threaded interface. This design enables the valve body 21 to be firmly connected to the foamer 1 and the extension rod 3 through threads, forming a complete and sealed fluid channel. The internal space of the valve body 21 provides the necessary space for the installation and operation of the valve core 22 and the spring 23. The valve core 22 is the core component for realizing the function of the one-way valve 2. One end of the spring 23 is connected to the valve core 22, and the other end is fixed to the inner surface of the connecting end of the valve body 21 and the extension rod 3. Under the elastic force of the spring 23, the valve core 22 can be tightly attached to the inner surface of the valve body 21 on the side close to the foamer 1, forming an initial sealing state. When fluid (i.e., foaming material) flows from the foamer 1 through the channel into the valve body 21, the fluid pressure pushes the valve core 22 toward the extension rod 3, compressing the spring 23. At this point, the fluid is able to pass smoothly through the gap between the valve core 22 and the valve body 21 and continue to flow toward the extension rod 3. When the foamer 1 stops supplying foaming material to the valve body 21, the valve core 22 loses the thrust of the fluid pressure. At this point, the spring 23 begins to naturally expand, pushing the valve core 22 back into contact with the inner surface of the valve body 21 near the foamer 1, restoring the initial sealing state. In this way, the one-way valve 2 effectively prevents backflow of the fluid. To improve the sealing performance of the one-way valve 2 and prevent fluid leakage through the tiny gap between the valve core 22 and the valve body 21, an O-ring 24 is provided at the connection between the valve core 22 and the valve body 21. The O-ring 24 is made of rubber material. With its good elasticity and sealing properties, the O-ring 24 can effectively fill and seal any small gap between the valve core 22 and the valve body 21, ensuring that the one-way valve 2 can maintain a good sealing effect under various working conditions.

[0060] The one-way valve of the utility model realizes one-way flow and high-efficiency sealing of the fluid through the precisely designed valve body, valve core, spring and O-ring, and effectively prevents backflow and leakage.

[0061] like Figure 2 As shown, according to one embodiment of the present invention, a C-type silencer exhaust throttle valve 31 is further provided on the extension rod 3 ; the C-type silencer exhaust throttle valve 31 is used to control the flow rate of the foaming material passing through the extension rod 3 .

[0062] Preferably, the tube wall of the extension rod 3 is provided with an internal thread, one end of the C-type silencer exhaust throttle valve 31 is milled with an external thread, and the extension rod 3 and the C-type silencer exhaust throttle valve 31 are connected through threads.

[0063] In this embodiment, a C-type silencer exhaust throttle valve 31 is additionally provided on the extension rod 3. This design aims to precisely control the flow rate of the foaming material passing through the interior of the extension rod 3 through the C-type silencer exhaust throttle valve 31, thereby achieving more refined flow management. Specifically, the tube wall of the extension rod 3 is deliberately provided with an internal thread, while one end of the C-type silencer exhaust throttle valve 31 is milled with a matching external thread. This design allows the extension rod 3 and the C-type silencer exhaust throttle valve 31 to be firmly combined together through a threaded connection, which not only ensures the stability of the structure but also facilitates installation and disassembly. Through such a design, the user can adjust the opening degree of the C-type silencer exhaust throttle valve 31 according to actual needs, thereby achieving effective control of the flow rate of the foaming material.

[0064] The utility model adds a C-type silencer exhaust throttle valve on the extension rod and uses a threaded connection method to ensure structural stability and ease of operation, thereby achieving precise control of the flow rate of the foaming material and improving the precision and practicality of flow management.

The adjustable triangular bracket 4 primarily consists of a bracket support plate 41, a handwheel 42, a bracket rotating sleeve 43, a bracket auxiliary support 44, bracket legs 45, a universal coupling 46, and bracket feet 47. The bracket support plate 41 is a thin, annular plate with an inner diameter identical to the outer diameter of the extension rod 3, ensuring that the bracket support plate 41 fits snugly and stably on the extension rod 3. The handwheel 42 is securely attached to the extension rod 3 via a threaded connection. The bracket rotating sleeve 43 also fits snugly on the outside of the extension rod 3 and, together with the bracket support plate 41, provides a stable support base for the adjustable triangular bracket 4. The bracket legs 45 are connected to the bracket rotating sleeve 43 and the universal coupling 46, respectively, via rotating shafts, enabling flexible rotation and angle adjustment of the bracket legs. The bracket auxiliary support 44 is connected between the bracket support plate 41 and the bracket legs 45 via a rotating shaft, enhancing the overall stability and load-bearing capacity of the bracket. Universal coupling 46, a key component connecting support legs 45 and support feet 47, allows support feet 47 to be freely adjusted in direction and angle within a certain range to adapt to different ground conditions and usage requirements. This design ensures that the entire adjustable triangular support 4 is not only structurally stable but also flexible, meeting the needs of various application scenarios.

[0071] According to an embodiment of the present invention, the guide rod 5 is connected to the extension rod 3 via a thread; the length of the guide rod 5 is selected according to the actual size and shape of the hole in the ship.

[0072] In this embodiment, the guide rod 5 and the extension rod 3 are connected by a threaded connection. This design not only ensures a secure connection between the two, but also provides the user with the flexibility to replace the guide rod 5 with different lengths according to actual needs. In actual use, when faced with ship holes of different sizes and shapes, the user can simply screw and install the guide rod 5 that matches the hole size.

[0078] Example 2

[0079] like Figure 1-3 As shown, according to an embodiment of the present invention, a marine foaming plugging device includes a foamer 1, which includes an outer tube 11. A switch button 12 is installed on the outer tube wall of the outer tube 11, and a central shaft sleeve 13 is arranged inside.

The bracket support plate 41 is floatingly sleeved on the extension rod 3, the handwheel 42 is threadedly connected to the extension rod 3, and the bracket rotating sleeve 43 is floatingly sleeved on the extension rod 3.

[0083] like Figure 1-2 As shown, the guide rod 5 is connected to the extension rod 3 through a thread, and the guide rod 5 of different lengths can be replaced according to the actual size and shape of the hole in the ship.

[0084] The airbag 6 is made of materials such as nitrile rubber, nylon cloth, and pure rubber that have good elasticity, wear resistance, and strong adaptability.

[0085] The foaming material stored in the foamer 11 is polyurethane or polyurethane with nano-silicon dioxide added.

[0086] The O-ring 24 is made of rubber.

[0087] The utility model can quickly inject foaming material (such as polyurethane or polyurethane with added nano-silica) into the hole in the ship through the design of the foamer. After the foaming material expands, it forms a tight sealing layer, which effectively prevents the water from continuing to leak and improves the plugging efficiency; the design of the one-way valve and the extension rod allows the device to be flexibly operated at different angles and positions, and the one-way valve ensures the one-way flow of the foaming material and avoids the backflow phenomenon; the introduction of the adjustable triangular bracket allows the device to adapt to ship holes of different shapes and sizes by adjusting the angles of the handwheel and the bracket legs, and using a universal coupling, thereby enhancing the applicability and flexibility of the device; the C-type silencer exhaust throttle valve equipped on the extension rod allows the operator to adjust the foaming according to actual needs speed, which not only ensures the full filling of the foaming material, but also avoids waste and excessive foaming; the O-ring in the one-way valve is designed as a wearing part, which is convenient for regular inspection and replacement to ensure the sealing performance of the device; guide rods of different lengths can be replaced according to actual needs, which enhances the versatility and service life of the device; the airbag is made of materials with good elasticity, wear resistance and strong adaptability (such as nitrile rubber, nylon cloth, pure rubber, etc.), which ensures the reliability and durability of the device in harsh environments; the foaming material stored in the foamer also has good physical and chemical properties and can adapt to various plugging needs; the design of the C-type silencer exhaust throttle valve not only helps to control the foaming speed, but also effectively reduces the noise generated during the foaming process, which meets the requirements of environmental protection and crew health. With its high efficiency, flexibility, controllability, durability and environmental protection, this utility model provides strong technical support and guarantee for ship plugging operations.

[0088] The operating principle of this utility model is as follows:

[0089] Pass the guide rod 5 through the breach in the hull, adjust the triangular bracket 4, stabilize the position of the marine foaming plugging device, press the switch knob 12, and the high-pressure polyurethane stored in the foamer 1 will break through the hole in the central shaft sleeve 13, flow through the one-way valve 2, the extension rod 3, and the guide rod 5, and finally flow out from the holes around the guide rod 5 and converge in the airbag 6. As the space increases rapidly and the pressure decreases, the polyurethane begins to expand and harden, filling the entire airbag 6. After the expansion is completed, the airbag 6 can completely seal the entire breach and the inner wall. If there are irregular inner walls such as pipes and edges, it can adaptively deform to ensure that the entire breach is filled, so that seawater cannot enter the cabin, thereby achieving the plugging of the damaged cabin wall.

[0090] The adjustment process of the adjustable triangular bracket 4 is specifically as follows: first, the bracket legs 45 are opened, and the universal coupling 46 is adjusted so that the bracket legs 47 are perpendicular to the ship wall. The handle of the handwheel 42 is turned to rotate the handwheel 42 inward. Since the bracket support plate 41 is floating on the extension rod 3, the bracket support plate 41 is also rotated inward. In addition, the two ends of the bracket auxiliary support 44 are respectively connected to the bracket support plate 41 and the bracket legs 45 through the rotating shaft, and then the bracket legs 45 also move inward until the bracket legs 47 are completely pressed against the ship wall, reaching the optimal position.

[0091] Compared with the prior art, the present invention has significant advantages and benefits:

[0092] First, this utility model achieves efficient plugging of damaged bulkheads through an innovative operational process: precise guide rod penetration through the breach, fine-tuning of the triangular bracket, and immediate release of the foam material. During this process, the polyurethane foam rapidly expands and hardens around the guide rod, forming a robust sealing layer. Even with complex structures on the hull's inner wall (such as pipes and sharp corners), it can adaptively deform to ensure complete sealing of the breach and effectively prevent seawater intrusion, thus significantly ensuring the ship's navigational safety.

[0093] Secondly, by optimizing the formula of the foaming material and using high-strength, high-pressure-resistant polyurethane or polyurethane with added nano-silica, the physical properties of the foaming material have been significantly improved, allowing it to maintain a stable and effective sealing effect when facing high-pressure water flow or harsh sea conditions.

[0094] Furthermore, the design of an adjustable triangular bracket and extension rod not only solves the problem of instability during positioning of the leak-proof device, but also greatly improves the device's ability to penetrate and secure into breaches of various sizes and shapes. This design allows operators to flexibly adjust the device's position and angle based on actual conditions, ensuring efficient and accurate leak-proofing operations.

[0095] Furthermore, the airbag, made from high-quality materials such as nitrile rubber, nylon cloth, and pure rubber, not only enhances the device's adaptability to irregular breaches but also significantly improves the strength and durability of the overall structure. These materials also ensure the device's stability and reliability in harsh environments.

[0096] In summary, the present invention, with its simple structure, easy operation, light weight, and efficient and reliable plugging performance, has become an important guarantee for ship navigation safety. In emergency situations, the device can quickly and effectively perform plugging operations, buying valuable time for the crew, reducing losses, and ensuring the safe navigation of the ship.
