Description

Technical Field

[0001] This utility model relates to the technical field of marine leak-sealing equipment, and in particular to a rapid leak-sealing airbag for ships. Background Technology

[0002] During navigation, damage to the hull structure due to collisions, grounding, corrosion, or other reasons can lead to seawater intrusion, threatening the ship's safety. Timely and effective leak sealing is crucial to ensuring the safety of the ship and its personnel. With the increasing size and complexity of ships, traditional leak sealing tools are no longer sufficient to meet emergency needs. Developing new leak sealing devices that can adapt to complex underwater environments and achieve rapid installation and sealing has become an important issue in the field of ship safety.

[0003] Currently, ship leak-sealing airbags mostly use traditional connection methods in practical applications, such as threaded connections and clamp connections. Threaded connections fix the airbag to the air supply pipe by rotating and tightening the interface, and use sealing rings or gaskets to fill the gaps. Clamp connections align the airbag interface with the air supply pipe and then tighten it with metal clamps, relying on rubber sealing rings to achieve a seal. Installation is completed manually, and additional auxiliary tools are needed to ensure a tight connection.

[0004] However, in emergency leak sealing scenarios, threaded connections require divers to precisely align the threads and rotate and tighten them multiple times. The operation is easily affected by water flow and pressure, resulting in connection time of several minutes or even longer. Although clamp connections are relatively simple to operate, the clamp tightening process also relies on tools, and the clamp is prone to loosening and the sealing ring may shift under the impact of water flow, making it difficult to complete a reliable connection in a short time. Therefore, a ship rapid leak sealing airbag is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ship rapid leak-sealing airbag, which aims to improve the existing technology that uses threaded connections, which requires divers to accurately align the threads and rotate and tighten them multiple times. The operation process is easily affected by water flow and water pressure, resulting in connection time of several minutes or even longer, which seriously affects the leak-sealing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ship rapid leak-sealing airbag includes an airbag body, an air supply pipe provided on the side wall of the airbag body, a valve fixedly connected to one end of the air supply pipe, a pressure gauge provided on the side wall of the valve, an air compressed cylinder provided on the side wall of the valve, and a connecting component provided on the side wall of the air supply pipe.

[0008] The connecting assembly includes a connecting tube and a fixing sleeve. The side wall of the connecting tube is fixedly connected to the side wall of the airbag body. The side wall of the fixing sleeve is fixedly connected to the other end of the air supply tube. The side wall of the connecting tube is slidably connected inside the fixing sleeve. A sliding sleeve is slidably connected to the side wall of the fixing sleeve. A spring is sleeved on the side wall of the fixing sleeve. One end of the spring is fixedly connected to the side wall of the fixing sleeve, and the other end of the spring is fixedly connected to the inside of the sliding sleeve. A limit ring is fixedly connected to the side wall of the fixing sleeve. A ball bearing is provided inside the fixing sleeve. A sealing assembly is provided on the side wall of the connecting tube.

[0009] As a further description of the above technical solution:

[0010] The sealing assembly includes an O-ring, the sidewall of which is attached to the sidewall of the connecting pipe.

[0011] As a further description of the above technical solution:

[0012] The sliding sleeve sidewall is attached to the ball sidewall, and the ball sidewall is slidably connected inside the connecting tube.

[0013] As a further description of the above technical solution:

[0014] The connecting pipe has an installation groove inside, and the side wall of the O-ring seal is slidably connected inside the installation groove.

[0015] As a further description of the above technical solution:

[0016] An installation sleeve is fixedly connected inside the fixed sleeve, and an extrusion plate is slidably connected inside the installation sleeve. The side wall of the extrusion plate is attached to the side wall of the O-ring seal.

[0017] As a further description of the above technical solution:

[0018] A second spring is provided inside the mounting sleeve. One end of the second spring is fixedly connected inside the mounting sleeve, and the other end of the second spring is fixedly connected to the side wall of the extrusion plate.

[0019] As a further description of the above technical solution:

[0020] A limiting ring is fixedly connected to the side wall of the extrusion plate, and the side wall of the limiting ring is slidably connected inside the mounting sleeve.

[0021] As a further description of the above technical solution:

[0022] A traction handle is fixedly connected to the side wall of the airbag body. The traction handle is used to connect a traction rope, which facilitates pulling the rope to release the airbag after depressurization.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pushing the sliding sleeve to overcome the elastic force of the spring and slide it backward, the through hole on the fixed sleeve is exposed, allowing the ball to roll towards the connecting tube. When the connecting tube is further inserted and the annular groove on its outer wall aligns with the ball, the sliding sleeve is released to squeeze the ball. Under the pressure of the inner wall of the sliding sleeve, the ball is stuck into the groove, realizing the rapid connection of the airbag. This solves the problem that some ship quick-plugging airbags are connected by threads, which requires divers to accurately align the threads and rotate and tighten them multiple times. The operation process is easily affected by water flow and water pressure, resulting in a connection time of several minutes or even longer, which seriously affects the plugging efficiency. The above structure improves the connection efficiency of the airbag.

[0025] 2. In this utility model, when the connecting pipe is inserted into the fixing sleeve, the O-ring in the mounting groove initially contacts the inner wall of the mounting sleeve, forming the first sealing line. During the process of inserting the connecting pipe into the fixing sleeve, the extrusion plate will fit against the O-ring. The extrusion plate is pushed towards the O-ring by the second spring, so that the O-ring is subjected to radial extrusion, further filling the gap between the connecting pipe and the mounting sleeve, and enhancing the sealing effect.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-4 This utility model provides an embodiment of a ship rapid leak-sealing airbag, including an airbag body 1. The airbag body 1 is used to fill with gas and fit against the damaged area of ​​the ship to block the water flow and prevent seawater from rushing into the cabin. It can quickly isolate the damaged opening and buy time for ship rescue. The side wall of the airbag body 1 is provided with an air supply pipe 2. One end of the air supply pipe 2 is fixedly connected to a valve 3. The valve 3 is used to control the gas flow. The air passage can be opened or closed at any time during the inflation process, which can accurately control the inflation amount of the airbag body 1 and avoid over-inflation or under-inflation. The side wall of the valve 3 is provided with a pressure gauge 4. The pressure gauge 4 is used to monitor the air pressure value inside the airbag body 1 in real time, so that the operator can intuitively grasp the airbag pressure status, ensure the safety of the leak sealing operation, and avoid the airbag rupture due to excessive air pressure. The side wall of the valve 3 is provided with an air compressor cylinder 5. The air compressor cylinder 5 provides a high-pressure gas source for the airbag body 1 to ensure the power supply for rapid leak sealing. The side wall of the air supply pipe 2 is provided with a connecting component.

[0037] The connecting assembly includes a connecting tube 7 and a fixing sleeve 8. The side wall of the connecting tube 7 is fixedly connected to the side wall of the airbag body 1, and the side wall of the fixing sleeve 8 is fixedly connected to the other end of the air supply tube 2. The side wall of the connecting tube 7 is slidably connected inside the fixing sleeve 8. The two work together to form a plug-in connection structure, which facilitates quick assembly and disassembly. A sliding sleeve 9 is slidably connected to the side wall of the fixing sleeve 8. A spring 12 is fitted on the side wall of the fixing sleeve 8. One end of the spring 12 is fixedly connected to the side wall of the fixing sleeve 8, and the other end of the spring 12 is fixedly connected to the inside of the sliding sleeve 9. The spring 12 provides a restoring force for the sliding sleeve 9, so that the sliding sleeve 9 maintains its initial position when not subjected to external force, which plays a role in positioning and locking. Under the action of the spring 12, the sliding sleeve 9 can slide along the side wall of the fixing sleeve 8, cooperating with... The fixed sleeve 8 moves back and forth. The side wall of the fixed sleeve 8 is fixedly connected to the limiting ring 10. The limiting ring 10 is used to limit the sliding stroke of the sliding sleeve 9 and prevent it from sliding out of the fixed sleeve 8. The fixed sleeve 8 is provided with a ball 11. The ball 11 is used to be inserted into the groove of the connecting tube 7 to lock the connecting tube 7 and the fixed sleeve 8. Its spherical design can reduce friction and facilitate flexible rolling. The side wall of the sliding sleeve 9 is attached to the side wall of the ball 11. The side wall of the ball 11 is slidably connected to the inside of the connecting tube 7. The sliding sleeve 9 squeezes the ball 11 to make it lock in the groove of the connecting tube 7, realizing a quick and stable connection between the airbag body 1 and the air supply tube 2, which greatly shortens the connection time of underwater operation and improves the leak sealing efficiency. The side wall of the connecting tube 7 is provided with a sealing component.

[0038] Reference Figures 4-7The sealing assembly includes an O-ring 13, which fills the gap between the connecting pipe 7 and the fixing sleeve 8, sealing the gas and preventing leakage. Its elastic material tightly conforms to the connection surface, effectively improving the sealing effect. The sidewall of the O-ring 13 is attached to the sidewall of the connecting pipe 7. An installation groove 15 is provided inside the connecting pipe 7 to fix the position of the O-ring 13, preventing it from shifting or falling off during connection and ensuring reliable sealing. The sidewall of the O-ring 13 is slidably connected inside the installation groove 15. This combination allows the O-ring 13 to be securely installed and can deform moderately under pressure, achieving better gap filling and enhanced sealing performance. An installation sleeve 14 is fixedly connected inside the fixing sleeve 8. An extrusion plate 17 is slidably connected inside the installation sleeve 14, with its sidewall attached to the sidewall of the O-ring 13. A second spring 16 is provided inside the installation sleeve 14, with one end fixedly connected inside the installation sleeve 14 and the other end fixedly connected to the extrusion plate 17. Spring 16 on the side wall of plate 17 provides continuous compressive force to the compression plate 17, ensuring that the O-ring seal 13 remains compressed even under pressure fluctuations inside the airbag, maintaining good sealing performance. Spring 16, in conjunction with the compression plate 17, performs reciprocating linear motion, achieving adaptive adjustment of sealing pressure and improving sealing reliability. Limiting ring 18 is fixedly connected to the side wall of compression plate 17, and the side wall of limiting ring 18 is slidably connected inside mounting sleeve 14. Limiting ring 18 limits the sliding range of compression plate 17, preventing excessive compression of O-ring seal 13 and damage, while ensuring the stability of compression plate 17's movement. Limiting ring 18 cooperates with mounting sleeve 14, allowing compression plate 17 to slide only within a preset track, achieving precise control of compression force to protect sealing components. A traction handle 6 is fixedly connected to the side wall of airbag body 1, connecting a traction rope for easy traction after depressurization to expel the airbag. Its robust structural design can withstand large tensile forces, ensuring safe and reliable airbag recovery.

[0039] Working principle: When using this device for leak sealing, first insert the connecting pipe 7 into the fixed sleeve 8 at the end of the air supply pipe 2. At this time, the sliding sleeve 9 is in its initial position under the action of the spring 12, restricting the ball 11 from sliding inward. Pushing the sliding sleeve 9 to squeeze the spring 12 backward exposes the through hole on the fixed sleeve 8, allowing the ball 11 to roll towards the connecting pipe 7. As the connecting pipe 7 continues to be inserted, when the annular groove on its outer wall aligns with the ball 11, the ball 11 is squeezed into the groove by the inner wall of the sliding sleeve 9, achieving a quick lock between the connecting pipe 7 and the fixed sleeve 8. After the connection is completed, the diver carries the airbag body 1 to the damaged area of ​​the ship, opens the valve 3, and the high-pressure gas in the compressed air cylinder 5 enters the airbag body 1 through the air supply pipe 2 and the connecting pipe 7. The pressure gauge 4 monitors the internal pressure of the airbag in real time to ensure that it does not exceed the safety threshold. The airbag body 1 inflates and expands, tightly fitting the damaged area of ​​the ship. At the location where water flow is prevented from entering, when the connecting pipe 7 is inserted into the fixing sleeve 8, the O-ring 13 in its mounting groove 15 initially contacts the inner wall of the mounting sleeve 14, forming the first sealing defense line. Spring 2 16 pushes the extrusion plate 17 to move towards the O-ring 13, causing the O-ring 13 to be radially compressed, further filling the gap between the connecting pipe 7 and the mounting sleeve 14, enhancing the sealing effect. After the airbag is inflated, the internal air pressure acts on the connecting pipe 7, causing it to generate an outward thrust. This thrust is transmitted to the extrusion plate 17 through the O-ring 13, compressing the spring 2 16, causing the O-ring 13 to be subjected to greater compression, achieving an adaptive sealing effect. After the leak sealing operation is completed, valve 3 is closed, and the gas in the airbag is slowly released. After the pressure gauge 4 shows that the pressure has dropped to a safe value, the airbag body 1 is pulled from underwater to the water surface through the traction rope connected to the traction handle 6, completing the recovery.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
