Description

Technical Field

[0001] This utility model relates to the field of marine pipeline technology, specifically a sealing structure for marine pipelines. Background Technology

[0002] Large ships require a large number of marine pipelines. During the post-processing and stacking of marine pipelines, debris can easily enter the pipelines, causing them to become obstructed or even blocked, thus affecting their operation.

[0003] Therefore, it is particularly important to find a sealing structure for marine pipelines that prevents foreign objects from entering during post-processing and stacking. Currently, existing sealing structures for marine pipelines are relatively complex. During installation, personnel need to adjust each fastener one by one, and the sealing effect is not good, making them prone to loosening. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing marine pipeline sealing structures being relatively complex, requiring personnel to adjust each fastener individually during installation, and having poor sealing effect and being prone to loosening. Therefore, this utility model proposes a sealing structure for marine pipelines.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A sealing structure for a marine pipeline includes a retaining ring and a top plate. A bolt is fixed to one side of the retaining ring, and a fixing seat is fixed to the outer side of the retaining ring. A gear one and a gear two are rotatably mounted on one side of the top plate. A lead screw is fixed to one side of the gear two. A plug is fixed to one side of the top plate. An adjusting rod is movably connected to one side of the top plate. A locking block is fixed to one end of the adjusting rod. A locking groove one is fixed to one side of the gear one. A rotating shaft is rotatably mounted on the inner side of the plug. A locking groove two is fixed to one end of the rotating shaft. A rotating disk is fixed to one end of the rotating shaft. A connecting rod is rotatably mounted on one side of the rotating disk. A sliding rod is rotatably mounted on one end of the connecting rod. A friction block is fixed to one end of the sliding rod. A fixing block is fixed to one side of the plug.

[0007] Preferably, two retaining rings are symmetrically arranged, each retaining ring having a semi-circular structure, and the two retaining rings are fixedly connected by bolts. Two gears are symmetrically arranged, and both gears mesh with gear one.

[0008] Preferably, the end of the lead screw away from the gear 2 passes through the top plate, and the lead screw and the top plate are rotatably connected, while the lead screw and the fixed seat are threadedly connected.

[0009] Preferably, the adjusting rod and the locking block are located on the same rotation axis, the locking block is adapted to the first locking slot, the locking block is adapted to the second locking slot, and the rotating shaft, the second locking slot, and the rotating disk are all located on the same rotation axis.

[0010] Preferably, the sliding rod is rotatably mounted on the end of the connecting rod away from the rotating disk, the friction block is fixed on the end of the sliding rod away from the connecting rod, the end of the sliding rod away from the connecting rod passes through the fixed block, and is slidably connected to the fixed block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By adjusting the lever, when the locking block is positioned in slot one, rotating the lever drives gear one to rotate, which in turn drives gear two, which in turn drives the lead screw to rotate. The lead screw then moves the fixed seat, which in turn moves the locking ring. When the locking ring is fixed to the outside of the pipe, the rotation of the lead screw moves the top plate towards the pipe, allowing the plug to be inserted into the pipe and sealing it. This simplifies the pipe sealing process. Further adjusting the lever position so the locking block is in slot two allows rotating the lever to rotate slot two, the rotating shaft, and the rotating disc. The rotating disc, under the action of the connecting rod, moves the sliding rod within the fixed block, adjusting the position of the friction block so that it fits snugly against the inner wall of the pipe. This increases the lateral friction between the top plate and the pipe, resulting in a better sealing effect and preventing the block from falling off. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1

[0020] Please see Figures 1-3 As shown, a sealing structure for a marine pipeline includes a retaining ring 1 and a top plate 4. A bolt 2 is fixed to one side of the retaining ring 1, used to fix the retaining ring 1 to the outside of the pipeline. A fixing seat 3 is fixed to the outside of the retaining ring 1. A gear 5 and a gear 6 are rotatably mounted on one side of the top plate 4. A screw 7 is fixed to one side of the gear 6. A plug 8, which can be made of rubber, is fixed to one side of the top plate 4 to improve the sealing effect when inserted into the pipeline, thus sealing the pipeline. The device is connected by an adjusting rod 9, with a locking block 10 fixed to one end of the adjusting rod 9. A locking groove 11 is fixed to one side of the gear 5. A rotating shaft 12 is rotatable inside the plug 8. A locking groove 13 is fixed to one end of the rotating shaft 12. A rotating disk 14 is fixed to one end of the rotating shaft 12. A connecting rod 15 is rotatable to one side of the rotating disk 14. A sliding rod 16 is rotatable to one end of the connecting rod 15. A friction block 17 is fixed to one end of the sliding rod 16 to increase friction and improve the sealing effect of the plug 8. A fixing block 18 is fixed to one side of the plug 8.

[0021] Example 2

[0022] Please see Figures 1-3As shown, two retaining rings 1 are symmetrically arranged, each with a semi-circular structure. The two retaining rings 1 are fixedly connected by bolts 2, which can fix the two retaining rings 1 to the outside of the pipe. Two gears 6 are symmetrically arranged, each meshing with gear 5. The end of the lead screw 7 away from gear 6 passes through the top plate 4, and the lead screw 7 is rotatably connected to the top plate 4. The lead screw 7 is threadedly connected to the fixed seat 3. The adjusting rod 9 and the retaining block 10 are located on the same axis of rotation. The retaining block 10 and the retaining groove 11 are... The components are compatible. By pulling the adjusting rod 9 outward, the adjusting rod 9 moves the locking block 10 into the locking groove 11, where the locking block 10 engages. Rotating the adjusting rod 9 drives the gear 5 to rotate, which in turn drives the meshing gear 6 to rotate. The gear 6 then drives the lead screw 7 to rotate, which in turn drives the meshing fixed seat 3 to move and adjust. Since the fixed seat 3 is fixed to the retaining ring 1, the rotation of the lead screw 7 allows the top plate 4 to move towards the pipe. The pipe moves to one side, causing the plug 8 to engage inside the pipe, simplifying the sealing process. The locking block 10 and the locking groove 13 are compatible. The rotating shaft 12, the locking groove 13, and the rotating disk 14 are all located on the same axis of rotation. The sliding rod 16 is rotatably mounted on the end of the connecting rod 15 away from the rotating disk 14. The friction block 17 is fixed to the end of the sliding rod 16 away from the connecting rod 15. The end of the sliding rod 16 away from the connecting rod 15 passes through the fixing block 18 and is slidably connected to the fixing block 18. The adjusting rod 9 moves inward. The adjusting rod 9 drives the locking block 10 to engage in the second locking groove 13. Rotating the adjusting rod 9 causes the second locking groove 13, the rotating shaft 12, and the rotating disk 14 to rotate. Under the action of the connecting rod 15, the rotating disk 14 drives the sliding rod 16 to move and adjust within the fixed block 18. The sliding rod 16 then drives the friction block 17 to move and adjust, so that the friction block 17 moves to fit against the inner wall of the pipe, thereby increasing the lateral friction between the top plate 4 and the pipe. This results in a better sealing effect for the plug 8 and makes it less prone to loosening.

[0023] In use, this invention uses bolts 2 to fix two retaining rings 1 to the outside of the pipe. Pulling the adjusting rod 9 outwards moves the retaining block 10 into the retaining groove 11, where it engages. Rotating the adjusting rod 9 drives gear 5, which in turn drives gear 6, which in turn drives screw 7, which in turn moves the fixed seat 3. Since the fixed seat 3 is fixed to the retaining rings 1, the rotation of screw 7 moves the top plate 4 towards one side of the pipe, allowing the plug to... The plug 8 is inserted into the pipe, making the pipe sealing process easier. Then, the adjusting rod 9 is moved inward, causing the adjusting rod 9 to drive the locking block 10 to engage in the locking groove 13. Rotating the adjusting rod 9 can drive the locking groove 13, the rotating shaft 12, and the rotating disk 14 to rotate. Under the action of the connecting rod 15, the rotating disk 14 can drive the sliding rod 16 to move and adjust within the fixed block 18. The sliding rod 16 can then drive the friction block 17 to move and adjust, so that the friction block 17 moves to fit against the inner wall of the pipe, thereby increasing the lateral friction between the top plate 4 and the pipe. This results in a better sealing effect for the plug 8, making it less prone to loosening.
