Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] An oil pipeline rapid leak plugging device, including a first arc-shaped fixing plate 1 and a first clamping plate 11. The first clamping plate 11 is used for pre-leak plugging, and the first arc-shaped fixing plate 1 is used to fix the first clamping plate 11. A first connecting block 2 is fixedly connected to the surface of the first arc-shaped fixing plate 1 for connecting the first arc-shaped fixing plate 1 to the surface of a connecting rotating shaft 3. The surface of the first connecting block 2 is rotatably connected to the connecting rotating shaft 3, which is used as a bearing to connect the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4. The surface of the connecting rotating shaft 3 is rotatably connected to the second arc-shaped fixing plate 4 for cooperating with the first arc-shaped fixing plate 1 to fix the first clamping plate 11 and the second clamping plate 15. A second connecting block 5 is fixedly connected to the surface of the second arc-shaped fixing plate 4 for connecting the second arc-shaped fixing plate 4 to the surface of the connecting rotating shaft 3. A connecting shaft 6 is fixedly connected to the surface of the second arc-shaped fixing plate 4 for connecting a plugging block 7. The surface of the connecting shaft 6 is rotatably connected to the plugging block 7 for plugging on the surface of a fixing block 8 to fix the connection between the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4. A fixing block 8 is fixedly connected to the surface of the first arc-shaped fixing plate 1 for plugging the plugging block 7. A counteracting spring 9 is fixedly connected to the surface of the fixing block 8 for pushing a limiting block 10 to plug on the surface of the plugging block 7. The surface of the counteracting spring 9 is fixedly connected to the limiting block 10 for plugging on the surface of the plugging block 7 to limit the position of the fixed plugging block 7. A fixing shaft 12 is fixedly connected to the surface of the first clamping plate 11 for connecting the second clamping plate 15. A buckle 13 is fixedly connected to the surface of the first clamping plate 11 for plugging at a clamping groove 16 to fix the connection between the first clamping plate 11 and the second clamping plate 15. A first sealing gasket 14 is fixedly connected to the surface of the first clamping plate 11 for improving the sealing performance of the connection between the first clamping plate 11 and the oil pipeline. The surface of the first clamping plate 11 is rotatably connected to a second clamping plate 15 for cooperating with the first clamping plate 11 to plug the leak of the oil pipeline. A clamping groove 16 is formed on the surface of the second clamping plate 15 for plugging the buckle 13. A second sealing gasket 17 is fixedly connected to the surface of the second clamping plate 15 for improving the sealing performance of the connection between the second clamping plate 15 and the oil pipeline.

[0024] Furthermore, the first arc-shaped fixing plate 1 is rotatably connected to the surface of the connecting rotating shaft 3 through the first connecting block 2, the second arc-shaped fixing plate 4 is rotatably connected to the surface of the connecting rotating shaft 3 through the second connecting block 5, and the second arc-shaped fixing plate 4 is rotatably connected to the surface of the first arc-shaped fixing plate 1 through the connecting rotating shaft 3. The connecting rotating shaft 3 connects the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 together so that the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 can be unfolded and combined through the connecting rotating shaft 3, facilitating the installation of the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 on the surface of the pipeline.

[0025] Further, the connecting shafts 6 are symmetrically distributed in two groups on the surface of the second arc-shaped fixing plate 4. The distribution of the two groups of connecting shafts 6 connects the two inserting blocks 7, and fixes the second arc-shaped fixing plate 4 on the surface of the first arc-shaped fixing plate 1 from both sides of the second arc-shaped fixing plate 4. A limiting groove is formed on the surface of the inserting block 7 for inserting the limiting block 10 to fix the position of the inserting block 7. The inserting block 7 is rotatably connected to the surface of the second arc-shaped fixing plate 4 through the connecting shaft 6. Rotating the inserting block 7 can make the inserting block 7 rotate on the surface of the second arc-shaped fixing plate 4.

[0026] Further, the fixing blocks 8 are symmetrically distributed in two groups on the surface of the first arc-shaped fixing plate 1. The two fixing blocks 8 are provided for inserting the two inserting blocks 7. A slot is formed on the surface of the fixing block 8 for inserting the inserting block 7. The inserting block 7 is inserted and connected to the surface of the fixing block 8 through the connecting shaft 6. Rotating the inserting block 7 can be inserted on the surface of the fixing block 8. The two ends of the abutting spring 9 are fixedly connected to the surface of the fixing block 8 and the limiting block 10. The limiting block 10 is movably connected to the surface of the fixing block 8 through the abutting spring 9. The deformation of the abutting spring 9 drives the limiting block 10 to move on the surface of the fixing block 8. The abutting springs 9 are evenly distributed in three groups on the surface of the limiting block 10. The three abutting springs 9 improve the tightness of the connection between the limiting block 10 and the inserting block 7.

[0027] Further, the limiting block 10 is inserted and connected to the surface of the inserting block 7 through the abutting spring 9. The inserting block 7 is fixedly connected to the surface of the first arc-shaped fixing plate 1 through the limiting block 10. The second arc-shaped fixing plate 4 is fixedly connected to the surface of the first arc-shaped fixing plate 1 through the inserting block 7. Rotating the inserting block 7 is inserted at the fixing block 8. The front end of the inserting block 7 abuts against the surface of the limiting block 10, so that the limiting block 10 drives the abutting spring 9 to move. The abutting spring 9 deforms. After the inserting block 7 is completely inserted into the fixing block 8, the abutting spring 9 drives the limiting block 10 to be inserted on the surface of the inserting block 7 to restore its original state, so as to limit the position of the inserting block 7.

[0028] Further, the buckles 13 are symmetrically distributed in two groups on the surface of the first clamping plate 11. The distribution of the two groups of buckles 13 can fix the first clamping plate 11 on the surface of the second clamping plate 15 from both sides of the first clamping plate 11. The clamping grooves 16 are symmetrically distributed in two groups on the surface of the second clamping plate 15 for inserting the two buckles 13. The second clamping plate 15 is rotatably connected to the surface of the first clamping plate 11 through the fixed shaft 12. The buckle 13 is inserted and connected to the surface of the first clamping plate 11 and the clamping groove 16. The first clamping plate 11 is fixedly connected to the surface of the second clamping plate 15 through the buckle 13. Rotating the first clamping plate 11 can drive the buckle 13 to rotate, so that the buckle 13 is inserted at the clamping groove 16 to fix the connection between the first clamping plate 11 and the second clamping plate 15.

[0029] Further, the first gasket 14 is rotatably connected to the surfaces of the first clamping plate 11 and the second clamping plate 15. Rotating the first clamping plate 11 can drive the first gasket 14 to rotate, so that the first gasket 14 adheres to the surface of the oil pipeline to plug the leak of the oil pipeline. The second gasket 17 is rotatably connected to the surfaces of the second clamping plate 15 and the first clamping plate 11. Rotating the second clamping plate 15 can drive the second gasket 17 to rotate, so that the second gasket 17 adheres to the surface of the oil pipeline to plug the leak of the oil pipeline.

[0030] Working principle: When using the first arc-shaped fixing plate 1, first rotate and unfold the first clamping plate 11 and the second clamping plate 15 through the fixed shaft 12, then place them above the damaged oil pipeline, and then rotate the first clamping plate 11 and the second clamping plate 15 so that the first gasket 14 and the second gasket 17 are tightly attached to the surface of the oil pipeline. Insert the buckle 13 into the card slot 16 to fix the first clamping plate 11 and the second clamping plate 15 on the surface of the oil pipeline. Then take the first arc-shaped fixing plate 1, rotate and unfold the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 through the connecting rotating shaft 3, then place them above the first clamping plate 11 and the second clamping plate 15, and then rotate the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 so that the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 enclose the first clamping plate 11 and the second clamping plate 15. At this time, rotate the plug-in block 7 and insert it into the fixed block 8. The front end of the plug-in block 7 abuts against the surface of the limit block 10, so that the limit block 10 drives the abutting spring 9 to move, and the abutting spring 9 deforms. After the plug-in block 7 is completely inserted into the fixed block 8, the abutting spring 9 drives the limit block 10 to be inserted on the surface of the plug-in block 7 to restore its original shape, so as to limit the position of the plug-in block 7, thereby fixing the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 4 on the pipeline surface to plug the leak of the oil pipeline.
