Description

Technical Field

[0001] The invention belongs to the technical field of oil leakage, and in particular relates to an oil leakage rapid plugging device. Background Art

[0002] Oil leakage is a serious environmental problem. It usually occurs during the storage, transportation or production of oil and its refined products. When these substances leak out accidentally, it will not only lead to a huge waste of natural resources, but may also have a profound impact on the ecological environment, including polluting the soil, water and air, destroying biodiversity, and even affecting human health. Therefore, plugging devices are used to plug the leakage location of the oil pipeline, control the leakage range, and prevent further spread of pollution.

[0003] In the Chinese patent with publication number CN206723705U, a device for quickly plugging leaks in oil transportation pipelines is mentioned, including a first clamp, a second clamp, and a plug. The top of the plug is provided with a groove, and one end of the first clamp and the second clamp are provided with a connecting mechanism, and the other end is provided with a convex edge. The connecting mechanism is provided with a fixing plate, and a drill rod is provided at the central position of the fixing plate. An adjustment handle is provided at one end of the drill rod, and a boss is provided at the other end. The boss is inserted into the groove of the plug, and bolts are inserted into the convex edges of the first clamp and the second clamp, and nuts are provided on the bolts. The device has a simple structure and is easy to operate. It can quickly plug leaks on oil pipelines when the oil pipeline is transporting oil, avoiding affecting the oil production when repairing the leak.

[0004] During the use of this device, its fixing mechanism relies only on a single bolt and nut system. This fixing method may seem stable in the initial stage, but with the passage of time and the influence of external environmental factors such as temperature fluctuations and pipeline vibrations, the tightness between the bolts and nuts will gradually weaken, leading to loosening problems. Once the fixing device loosens, the leakage point that was originally effectively blocked will be exposed again, causing oil to leak again, thus threatening environmental safety and the normal progress of production activities.

[0033] Embodiment 1:

[0034] See also Figure 1 - Figure 6 As shown, a rapid plugging device for oil leakage comprises:

[0035] A lower blocking seat 1 and an upper blocking seat 2;

[0039] The outer surfaces of the two fixing mechanisms 4 are fixedly connected with a plurality of first connecting blocks 5 at equal distances. The first connecting blocks 5 are each provided with a first through-slot 6 at one end away from the fixing mechanism 4, and threaded rods 7 are movably inserted and connected together in two transverse first through-slots 6. Two fastening nuts 8 are threadedly connected to the outer surfaces of the threaded rods 7 on both sides.

[0042] As can be seen from the above, the lower sealing seat 1 and the upper sealing seat 2 are tightly fitted to the surface of the oil pipeline outside the leakage point. In this process, the second rubber layer 16 significantly enhances the sealing effect between the lower sealing seat 1 and the upper sealing seat 2, effectively preventing leakage, while the first rubber layer 15 ensures seamless fit between the extension pipe 14 and the oil pipeline, further consolidating the tightness of the sealing.

[0045] As can be seen from the above, the first arc plate 41 is pressed against the outer surface of the extension tube 14, the second arc plate 441 is rotated, and the second connecting block 442 is rotated on the outer surface of the fixed tube 43 until the second arc plate 441 is in contact with the lower part of the extension tube 14, and then the movable rod 443 is pulled to make the movable rod 443 flip over, and the electric telescopic rod 45 is started. The output end of the electric telescopic rod 45 extends and pushes the insertion column 46 to be inserted into the insertion tube 446, and the insertion column 46 pushes the insertion tube 446 to move upward. Through a series of linkage mechanisms, the movable rod 443 and the second arc plate 441 are driven to tighten toward the center, thereby achieving the clamping of the extension tube 14.

[0047] The second arc plate 441 is in close contact with the outer surface of the upper blocking seat 2 .

[0048] As can be seen from the above, by movably inserting the second insertion slot 444 and the insertion rod 47 together, the insertion rod 47 can be used to limit the flipping position of the movable rod 443.

[0049] Embodiment three:

[0050] refer to Figure 5 and Figure 6 As shown, the injection structure 3 includes a connecting tube 31, an introduction tube 32, a guide tube 33 and a sealing tube structure 35. Three introduction tubes 32 are provided, and the three introduction tubes 32 are fixedly connected to the bottom end of the outer surface of the connecting tube 31. The guide tube 33 is fixedly connected to the outer surface of the top end of the connecting tube 31. A threaded groove 34 is provided on one side of the outer surface of the guide tube 33. The sealing tube structure 35 is movably inserted and connected to both ends of the outer surface of the guide tube 33 through a rotating shaft. The introduction tubes 32 are fixedly inserted and connected to the outer surface of the upper blocking seat 2.

[0051] The sealing tube structure 35 includes a screw rod 351, a movable frame 352, a fixed seat 353, a sealing tube column 354 and a rubber sleeve 355. The movable frame 352 is threadedly connected to the outer surface of the screw rod 351, the fixed seat 353 is bearing-connected to one end of the screw rod 351, the sealing tube column 354 is fixedly connected to one end of the fixed seat 353, the rubber sleeve 355 is fixedly connected to the outer surface of the sealing tube column 354, and the movable frame 352 is movably connected to the guide tube 33.

[0052] As can be seen from the above, the sealant is introduced into the connecting tube 31 through the guide tube 33, and is introduced into the sealing groove 12 through the three guide tubes 32. After the injection is completed, the movable frame 352 is pulled, and the movable frame 352 rotates at both ends of the guide tube 33, so that the sealing column 354 is located directly behind the guide tube 33, and the screw rod 351 is rotated. The screw rod 351 pushes the sealing column 354 to move through the fixed seat 353, so that the sealing column 354 and the rubber sleeve 355 are inserted into the guide tube 33, so that the input port of the guide tube 33 can be blocked, effectively preventing any possible leakage or backflow, and further consolidating the safety and reliability of the overall blocking operation.

[0053] Preferably, the rubber sleeve 355 and the pipe sealing column 354 are both movably inserted and connected in the introduction pipe 33.

[0054] As can be seen from the above, the input port of the introduction pipe 33 can be blocked.

[0055] Furthermore, the present invention is designed and applied to the case where an oil pipeline ruptures and causes oil leakage. When an oil pipeline leaks, the leakage point of the oil pipeline is first determined, and the lower plugging seat 1 and the upper plugging seat 2 are tightly fitted to the surface of the oil pipeline outside the leakage point, so that the lower plugging seat 1 and the upper plugging seat 2 are tightly fitted together, and the second rubber layer 16 is used to improve the tightness of the lower plugging seat 1 and the upper plugging seat 2, effectively preventing leakage, and the first rubber layer 15 is used to improve the tightness of the extension pipe 14 and the oil pipeline, so that there is a seamless fit between the extension pipe 14 and the oil pipeline, further consolidating the tightness of the plugging, and when the plugging pipe 11 is installed, the end of the partition 13 away from the sealing groove 12 is tightly fitted to the oil pipeline;

[0056] Then, the first arc plate 41 is pressed against the outer surface of the extension tube 14, the second arc plate 441 is rotated, and the second connecting block 442 fixedly connected to the second arc plate 441 is rotated on the outer surface of the fixed tube 43 until the second arc plate 441 is in contact with the lower part of the extension tube 14, and then the movable rod 443 is pulled to make the movable rod 443 flip over, and the second insertion slot 444 and the insertion rod 47 are inserted together. At this time, the insertion tube 446 is located directly above the insertion column 46, and the electric telescopic rod 45 is started. The output end of the electric telescopic rod 45 extends and pushes the insertion column 46 fixedly connected thereto to be inserted into the insertion tube 446, and the insertion column 46 pushes the insertion tube 446 to move upward, and the insertion tube 446 pulls the movable rod 443 fixedly connected thereto to move upward through the fixed plate 445 fixedly connected thereto, and the movable rod 443 pulls the second arc plate 441 movably connected thereto to move, thereby achieving a firm clamping of the extension tube 14, which greatly improves the stability of the overall structure.

[0057] In order to further enhance the blocking effect, the sealant pipe is threadedly connected to the guide pipe 33, and the sealant is introduced into the connecting pipe 31 through the guide pipe 33, and then introduced into the sealing groove 12 through the three introduction pipes 32, so that a solid sealing layer is quickly formed around the leakage point, effectively blocking the leakage source, and achieving the purpose of rapid and efficient blocking;

[0058] Finally, in order to consolidate the stability of the entire sealing system and avoid loosening due to external vibration, the threaded rod 7 is inserted into the first through-slot 6 on the two first horizontal connecting blocks 5, and then fastened with two fastening nuts 8, thereby improving the stability between the two fixing mechanisms 4 and avoiding detachment from the extension tube 14 due to vibration.
