Description

Technical Field

[0001] This utility model relates to the field of ship maintenance technology, specifically a leak-sealing device for ship pipeline maintenance. Background Technology

[0002] Ship pipelines, due to their long-term transport of media such as oil and water, are susceptible to corrosion, vibration, and other factors that can lead to pipe wall damage and leakage. When a pipeline leaks, it is necessary to use a leak-sealing device for temporary sealing in a timely manner before carrying out relevant maintenance work. Conventional temporary leak-sealing devices are usually clamp-type leak-sealing devices, which mainly consist of two symmetrical metal half-hoops and fastening bolts. An arc-shaped sealing gasket is installed inside. By fastening the two metal half-hoops to wrap around the pipeline and tightening the bolts, the half-hoops shrink, and the deformation of the sealing gasket fills the gap, thus quickly stopping the leak. This effectively solves the efficiency and safety problems of emergency leak sealing in ship pipelines during navigation and is widely used in daily maintenance and emergency repair scenarios of ship pipelines.

[0003] Existing pipe sealing devices typically only fit one type of pipe. However, since there are various pipe specifications on ships, a separate pipe sealing device is needed for each type of pipe. This results in high equipment procurement costs and occupies a significant amount of storage space. Furthermore, the installation of the pipe sealing device requires tightening multiple bolts, which is time-consuming and leads to low installation efficiency. In some narrow working conditions, tightening the bolts is also inconvenient. Therefore, a pipe sealing device for ship pipe maintenance is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leak-sealing device for ship pipeline maintenance, which solves the problem that existing pipeline leak-sealing devices mentioned in the background technology can usually only match one type of pipeline. Since there are various types of pipelines on ships, it is necessary to equip each type of pipeline with a separate leak-sealing device, resulting in high equipment procurement costs and occupying a lot of storage space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-sealing device for ship pipeline maintenance, comprising: two housings, the tops of which are connected by a hinge, and a rubber seal connected to the inner wall of each housing; and a fastening part, comprising a fastening rod and two grooved rods, the two grooved rods being respectively connected to the bottom of the two housings, each grooved rod having a long groove, the inner wall of the fastening rod having two protruding ridges, the two protruding ridges of the fastening rod being able to be respectively embedded in the long grooves of the two grooved rods, the inner wall of the fastening rod being slidably connected to the outer walls of the two grooved rods, and a first handle being connected to the bottom of the fastening rod; and a sealing part being provided inside the housing, the sealing part being able to utilize the water pressure from leaking water in the pipeline to enhance the sealing effect.

[0006] Preferably, the rubber seal is elastic, and when two rubber seals are fitted together, they can wrap around the surface of the pipe. The rubber seal can be adapted to pipes of various specifications.

[0007] Preferably, the sealing part includes two water bladders, both of which are installed on the inner wall of the housing. The two water bladders are located on both sides of the rubber seal. A second water pipe is connected through the rubber seal. A first water pipe is installed on the outer wall of the housing. The two ends of the first water pipe are connected to the two water bladders respectively. The second water pipe is connected to the first water pipe. Water in the rubber seal can flow to the two water bladders through the first water pipe and the second water pipe.

[0008] Preferably, the water bladders inside the two housings are arranged in a mirror image, and when the two water bladders inside the two housings come into contact, they squeeze each other to form a seal.

[0009] Preferably, the fastening part further includes a pressure relief mechanism, which includes two valve blocks. The two valve blocks are slidably connected to the inner walls of the two groove rods. Two springs are connected to the valve blocks. The ends of the springs away from the valve blocks are connected to the inner walls of the groove rods. The valve blocks are semi-circular and located on the movement trajectory of the buckle protrusion. When the buckle is slidably connected to the two groove rods, it can squeeze the two valve blocks to close them.

[0010] Preferably, the two housings, the two rubber seals, and the two grooved rods are provided with matching semi-circular grooves. When the two housings are closed, the two semi-circular grooves form a pressure relief channel. When the two valve blocks are closed, they can block the pressure relief channel.

[0011] Preferably, the fastening part further includes an assist mechanism, which includes a smooth rod. The smooth rod is installed on the outer wall of one of the housings, and a telescopic rod is rotatably connected to the smooth rod. A second handle is connected to the telescopic rod, and the telescopic rod can contact the first handle when it rotates.

[0012] As can be seen from the above technical solutions, the leak-sealing device for ship pipeline maintenance provided in the embodiments of this specification has at least the following beneficial effects:

[0013] 1. This utility model, through the design of the snap-fit ​​part, allows operators to flexibly open the two shells by pulling out the snap rod, facilitating installation onto the pipeline. The two shells can be closed and secured by inserting the snap rod, making operation convenient and greatly improving installation efficiency. The two rubber seals, when closed, utilize their elastic sealing properties to temporarily seal various pipe specifications, meeting the sealing needs of diverse pipe sizes. The sealing part ensures that the inner sides of the four water bladders tightly press against the outer wall of the pipeline, forming a second seal. When the water pressure at the leaking point causes water to seep through the rubber seals, the four water bladders can further seal the water within the two shells, improving the overall sealing effect.

[0014] 2. This utility model, through the setting of the assist mechanism, enables the staff to extend the lever arm by extending the telescopic rod, and to pry open the first handle relatively easily by pulling the second handle, thereby sliding the buckle. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-5 As shown, a leak-sealing device for ship pipeline maintenance includes: two housings 1, the tops of which are connected by hinges. A rubber seal 2 is connected to the inner wall of each housing 1. The rubber seal 2 is elastic and can wrap around the pipe surface when the two seals are in contact. The rubber seal 2 can adapt to various pipe specifications. When the two rubber seals 2 are closed, they contact the outer wall of the pipe. The rubber seal 2 is similar to a hollow hemisphere. When the edge of the rubber seal 2 contacts the outer wall of the pipe, it can slide and deform along the outer wall. The larger the outer diameter of the pipe, the greater the deformation amplitude of the rubber seal 2, and the greater the reaction force exerted by the rubber seal 2 on the pipe using its elasticity. Furthermore, when the two housings 1 are closed, the two rubber seals 2 also contact each other, forming an annular sealing member. The two rubber seals 2 can utilize their own elastic sealing characteristics to temporarily seal various pipe specifications.

[0026] It also includes a fastening part 3, which includes a fastening rod 32 and two grooved rods 31. The two grooved rods 31 are respectively connected to the bottom of the two housings 1. The grooved rods 31 are provided with long grooves. The inner wall of the fastening rod 32 is provided with two protruding ribs. The two protruding ribs of the fastening rod 32 can be respectively inserted into the long grooves of the two grooved rods 31. The inner wall of the fastening rod 32 is slidably connected to the outer wall of the two grooved rods 31. The bottom of the fastening rod 32 is connected to a first handle 33. After the fastening rod 32 is removed, the two housings 1 can be opened. The opened two housings 1 are then placed on the tube. On the way, manually squeeze the two shells 1 to close them, and the grooved rods 31 at the bottom of the two shells 1 will also fit together. Then, put one end of the buckle 32 onto one end of the two grooved rods 31. Match the long grooves of the two grooved rods 31 with the two protrusions of the buckle 32. Use the first handle 33 to slide the buckle 32 laterally to slide the buckle 32 onto the two grooved rods 31. After the buckle 32 is in place, the two grooved rods 31 are firmly fastened. At this time, the two shells 1 are also fixed, thus maintaining the closed state.

[0027] A sealing part 4 is provided inside the housing 1. The sealing part 4 can enhance the sealing effect by utilizing the water pressure from the leaking pipe. The sealing part 4 includes two water bladders 41, both of which are installed on the inner wall of the housing 1. The two water bladders 41 are located on both sides of the rubber seal 2. A second water pipe 43 is connected through the rubber seal 2. A first water pipe 42 is installed on the outer wall of the housing 1. The two ends of the first water pipe 42 are connected to the two water bladders 41 respectively. The second water pipe 43 is connected to the first water pipe 42. Water in the rubber seal 2 can flow into the two water bladders 41 through the first water pipe 42 and the second water pipe 43. The water bladders 41 in the two housings 1 are mirror images of each other. When the water bladders 41 in the two housings 1 come into contact, they squeeze each other to form a seal. Water first enters between the two rubber seals 2, and then enters the two first water pipes 42 through the two second water pipes 43. As the water pressure increases, the water enters the four water bladders 41 through the two first water pipes 42. The water bladders 41 are made of elastic material and can expand when filled with water. The two water bladders 41 in contact can form a sealing ring after being filled with water. As the water pressure in the two rubber seals 2 increases, the water pressure in the four water bladders 41 also increases, so that the inner side of the four water bladders 41 is tightly pressed against the outer wall of the pipe, forming a second seal. When the water pressure at the leaking point of the pipe is high and causes water to seep into the rubber seals 2, the seal of the four water bladders 41 can also seal the water inside the two shells 1, improving the overall sealing effect.

[0028] The fastening part 3 also includes a pressure relief mechanism 5, which includes two valve blocks 51. The two valve blocks 51 are slidably connected to the inner walls of the two groove rods 31. Two springs 52 are connected to the valve blocks 51. The ends of the springs 52 away from the valve blocks 51 are connected to the inner walls of the groove rods 31. The valve blocks 51 are semi-circular and located on the movement trajectory of the protrusion of the latch rod 32. When the latch rod 32 is slidably connected to the two groove rods 31, it can squeeze the two valve blocks 51, causing the two valve blocks 51 to close. Matching semi-circular grooves are provided on the two housings 1, the two rubber seals 2, and the two groove rods 31. When the two housings 1 are closed, the two semi-circular grooves form a pressure relief channel. After the two valve blocks 51 are closed, they can block the pressure relief channel. When the latch 32 is installed, the two protruding edges of the latch 32 slide along the sliding grooves of the two grooved rods 31 and can contact the semi-circular arc surface of the valve block 51. The protruding edges of the latch 32 apply a pushing force to the valve block 51, causing the two valve blocks 51 to move closer to each other until they close. At this time, the two valve blocks 51 block the pressure relief channel, achieving a seal. When disassembling the two housings 1, first slide the latch 32 until the latch 32 is separated from the two valve blocks 51. The two valve blocks 51 are separated and reset by the elastic force of the spring 52. At this time, the pressure relief channel is opened, and the water in the housing 1 is discharged. Then continue to disassemble the two housings 1 to avoid the water in the housing 1 spraying out when the two housings 1 are separated, which would affect the operators and the surrounding environment.

[0029] In this embodiment, the fastening part 3 allows the operator to easily open the two housings 1 by pulling out the fastening rod 32, facilitating installation onto the pipeline. The fastening rod 32 then secures the two housings 1, making the operation convenient, reducing the need for bolt installation, and significantly improving installation efficiency. The two rubber seals 2, when closed, utilize their elastic sealing properties to temporarily seal various pipe sizes, meeting the sealing needs of multiple pipe specifications. This eliminates the need for separate sealing devices for each pipe size, reducing equipment costs. The sealing part 4 ensures that the inner sides of the four water bladders 41 tightly press against the outer wall of the pipeline, forming a second seal. When the water pressure at the leak point is high, causing water to seep through the rubber seals 2, the four water bladders 41 can further seal the water within the two housings 1, improving the overall sealing effect.

[0030] Example 2

[0031] Please see Figure 1 , Figure 6 As shown, the fastening part 3 also includes an assisting mechanism 6, which includes a smooth rod 61. The smooth rod 61 is installed on the outer wall of one of the housings 1. A telescopic rod 62 is rotatably connected to the smooth rod 61. A second handle 63 is connected to the telescopic rod 62. When the telescopic rod 62 rotates, it can contact the first handle 33. The telescopic rod 62 is extended by the second handle 63. Then, the telescopic rod 62 is rotated so that it abuts against the first handle 33. At this time, the telescopic rod 62 can be used as a lever to pry the first handle 33. After the telescopic rod 62 is extended, the lever arm is lengthened. The operator can pry the first handle 33 more easily by pulling the second handle 63, thereby sliding the buckle 32.

[0032] In this embodiment, the auxiliary mechanism 6 enables the operator to extend the lever arm by extending the telescopic rod 62, and then easily pry open the first handle 33 by pulling the second handle 63, thereby sliding the latch 32.

[0033] In use, the leak-sealing device for ship pipeline maintenance of this utility model involves disassembling the latch 32, allowing the two housings 1 to open. The opened housings 1 are then placed over the pipeline, and manually squeezed to close them. The grooved rods 31 at the bottom of the two housings 1 also fit together. Then, one end of the latch 32 is fitted over one end of each grooved rod 31, aligning the long grooves of the two grooved rods 31 with the two protruding edges of the latch 32. Finally, the latch 32 is slid laterally using the first handle 33 to close the device. 32 slides onto the two grooved rods 31. After the latch 32 is in place, the two grooved rods 31 are firmly latched, and the two housings 1 are also fixed, thus maintaining a closed state. At the same time, the two rubber seals 2 come into contact with the outer wall of the pipe. The rubber seals 2 are similar to hollow hemispheres. When the edges of the rubber seals 2 come into contact with the outer wall of the pipe, they can slide along the outer wall of the pipe and deform. The larger the outer diameter of the pipe, the greater the deformation of the rubber seals 2. The rubber seals 2 use their elasticity to exert a reaction force on the pipe. The larger the size of the two housings 1, the more the two rubber seals 2 come into contact with each other after the two housings 1 are closed, forming a ring-shaped sealing component. The two rubber seals 2 can use their own elastic sealing characteristics to match the temporary sealing of various specifications of pipes. At the same time, there is a gap between the two housings 1 and the outer wall of the pipe to provide deformation space for the rubber seals 2. When sealing the pipe, the housings 1 do not come into contact with the outer wall of the pipe. With the setting of the fastening part 3, the operator can flexibly open the two housings 1 by pulling out the fastening rod 32, which is convenient for installation on the pipe. The two housings 1 can be closed and tightened by sleeve fastening rod 32. The operation is more convenient, reducing the operation steps of installation bolts and greatly improving the installation efficiency. With the setting of the two rubber seals 2, the two rubber seals 2 can use their own elastic sealing characteristics to match the temporary sealing of various specifications of pipes after they are closed, meeting the sealing needs of various specifications of pipes. It is not necessary to equip each specification of pipe with a sealing device, reducing equipment cost investment.

[0034] When the pipe leaks, the water first enters between the two rubber seals 2, and then enters the two first water pipes 42 through the two second water pipes 43. As the water pressure increases, the water enters the four water bladders 41 through the two first water pipes 42. The water bladders 41 are made of elastic material and can expand when flushed. The two water bladders 41 in contact can form a sealing ring after flushing. As the water pressure in the two rubber seals 2 increases, the water pressure in the four water bladders 41 also increases, so that the inner sides of the four water bladders 41 are tightly pressed against the outer wall of the pipe, forming a second seal. When the water pressure at the leak point is high and causes the rubber seals 2 to leak, the seal of the four water bladders 41 can also seal the water inside the two shells 1, improving the overall sealing effect.

[0035] When the pipe continues to leak, the water pressure inside the two housings 1 may make it difficult for the housings 1 to close when installing them. The pressure relief channel allows the water inside the rubber seal 2 to flow out, thus relieving pressure and allowing the two housings 1 to close properly. When the latch 32 is installed, the two protrusions of the latch 32 slide along the grooves of the two groove rods 31 and can contact the semi-circular arc surface of the valve block 51. The protrusions of the latch 32 apply a pushing force to the valve block 51, causing the two valve blocks 51 to move closer to each other until they close. At this time, the two valve blocks 51 block the pressure relief channel, achieving a seal. When disassembling the two housings 1, first slide the latch 32 until the latch 32 is separated from the two valve blocks 51. The two valve blocks 51 are separated and reset by the elastic force of the spring 52. At this time, the pressure relief channel opens, and the water in the housing 1 is discharged. Then continue to disassemble the two housings 1 to avoid water spraying out when the two housings 1 are separated, which could affect the workers and the surrounding environment.

[0036] When the water pressure inside the two housings 1 and the two rubber seals 2 is high, the two housings 1 will generate a force that separates them from each other, causing the two grooved rods 31 to press tightly against the latch rod 32. At this time, it is difficult to slide the latch rod 32. The operator can use the second handle 63 to extend the telescopic rod 62, and then rotate the telescopic rod 62 so that the telescopic rod 62 presses against the first handle 33. At this time, the telescopic rod 62 can be used as a lever to pry the first handle 33. After the telescopic rod 62 is extended, the lever arm is lengthened. The operator can then easily pry the first handle 33 by pulling the second handle 63, thereby sliding the latch rod 32.

[0037] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
