[0002] Oil and gas transportation refers to the process of transporting oil and natural gas from the production site to the consumption site. This process involves multiple links, including exploration, mining, gathering, storage and distribution. In the process of oil and gas transportation, pipelines need to be laid for transmission, and these pipelines will be buried underground. During the laying and use of pipelines, wear, corrosion and bumps will cause leakage points on the pipe wall of the transmission pipeline. During the temporary maintenance of oil and gas pipelines, sealing devices will be used to temporarily seal these leakage points.

[0003] The existing methods for plugging this type of leak mostly use wooden wedges and sealing glue. These operating methods are not easy to remove in combination with the oil and gas pipeline. Since the plugging of pipeline leakage points is to first perform a simple plugging, and then remove the simple plugging to repair the pipeline, the existing temporary plugging method makes it very inconvenient to handle the leakage point during subsequent repair operations on the pipeline. In view of this, this solution proposes a leakage plugging device for oil and gas pipelines to solve the above problems. Summary of the Invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides Figure 1-6 The leakage plugging device for oil and gas pipelines shown includes a T-shaped connecting block 1 and further includes:

[0029] A plugging piece is provided at the bottom of the T-shaped connecting block 1 and is used to plug leakage points in oil and gas pipelines;

[0030] Specifically, the blocking piece includes an arc-shaped block 2 , a surface of the arc-shaped block 2 away from the T-shaped connecting block 1 is set to be arc-shaped, and a sealing plug 3 is provided on the arc-shaped surface of the arc-shaped block 2 .

[0031] It should be noted that the sealing plug 3 is made of flexible and corrosion-resistant material. In this way, when the arc-shaped block 2 is pressed against the oil and gas pipeline to squeeze the sealing plug 3, the structural part of the sealing plug 3 can be inserted into the leakage point of the oil and gas pipeline. Under the deformation of extrusion, the sealing plug 3 is pressed against the pipe wall at the leakage point of the oil and gas pipeline. In this way, after ensuring that the sealing plug 3 is in close contact with the oil and gas pipeline, the sealing plug 3 can be used to fill and seal the leakage point of the oil and gas pipeline.

[0032] The two ends of the binding rope 4 are respectively connected to the two ends of the T-shaped connecting block 1. A support is provided in the middle of the binding rope 4 to position the binding rope 4 on the outer wall of the oil and gas pipeline;

[0033] Specifically, the supporting member includes:

[0034] The support block 5 has a top end formed into an arc surface;

[0035] Furthermore, a plurality of anti-skid grooves 501 are provided on the arc surface of the supporting block 5 , and the anti-skid grooves 501 are used to prevent the supporting block 5 from slipping when it is fitted onto the oil and gas pipeline.

[0036] The connecting sleeve 6 is fixedly connected to the bottom end of the supporting block 5;

[0037] Furthermore, a through slot 601 is provided in the middle of the connecting sleeve 6 , and the connecting sleeve 6 is sleeved on the outer wall of the binding rope 4 through the through slot 601 .

[0038] It should be noted that, through the setting of the support block 5, the arc surface at its top can be close to the wall of the oil and gas pipeline, so that the support block 5 can cooperate with the arc-shaped clamping block 2 to encircle the wall of the oil and gas pipeline, thereby ensuring that under the series connection of the binding rope 4, the T-shaped connecting block 1 presses against the sealing plug 3 and is close to the leakage point of the oil and gas pipeline, thereby ensuring the tight fit between the sealing plug 3 and the oil and gas pipeline, and thus ensuring the blocking of the leakage point of the oil and gas pipeline, and the connecting sleeve 6 uses the through groove 601 to ensure the insertion of the binding rope 4, and through such a structural setting, the insertion position between the connecting sleeve 6 and the binding rope 4 can also be changed, and then the setting position of the support block 5 is adjusted according to the actual connection method with the oil and gas pipeline, thereby ensuring the stability of the binding rope 4 when it is bound to the outer wall of the oil and gas pipeline.

[0039] The fastening mechanism includes multiple sets of fastening mechanisms respectively arranged at both ends of the T-shaped connecting block 1 , and the fastening mechanisms are used to fasten and lock the points where the binding rope 4 and the T-shaped connecting block 1 intersect.

[0040] Specifically, both ends of the T-shaped connecting block 1 are provided with insertion holes 101 in the vertical direction, and the two ends of the binding rope 4 are respectively inserted and connected with multiple insertion holes 101. Both sides of the T-shaped connecting block 1 are provided with thread grooves 102, and the multiple thread grooves 102 are respectively connected with the multiple insertion holes 101. The thread grooves 102 are used for the insertion connection of the fastening mechanism.

[0041] Furthermore, the fastening mechanism includes a fastening bolt 7, the threaded end of the fastening bolt 7 is threadedly inserted into the thread groove 102, and an extrusion groove 103 is provided on the inner wall of the multiple insertion holes 101 and on the side wall opposite to the thread groove 102. The extrusion groove 103 is used for the fastening bolt 7 to insert and extrude the binding rope 4 in the insertion hole 101.

[0042] It should be noted that, through the threaded insertion between the fastening bolt 7 and the threaded groove 102, when the fastening bolt 7 moves close to the T-shaped connecting block 1, it can gradually be inserted into the insertion hole 101, so that the binding rope 4 inserted in the insertion hole 101 will be squeezed. When the fastening bolt 7 continues to move in the direction close to the T-shaped connecting block 1, the fastening bolt 7 will squeeze part of the binding rope 4 into the extrusion groove 103. In this way, the inner wall of the extrusion groove 103 cooperates with the fastening bolt 7 to squeeze and fix the inserted part of the binding rope 4 in the insertion hole 101, so that the part of the binding rope 4 after insertion can be locked.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
