[0002] A natural gas pipeline refers to a pipeline that transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. During daily use, natural gas pipelines may be damaged due to aging, external collisions, etc., which will not only cause the gas supply to be blocked, but also cause safety hazards to life and property. Therefore, the timeliness of natural gas pipeline leakage remediation is very important.

[0003] When the existing natural gas pipeline leakage remediation device is in use, its general principle is to use two semicircular C-shaped rings or a large C-shaped ring to be sleeved on the outside of the damaged part of the pipeline and tightly press it, so as to wrap the damaged part of the pipeline to achieve leakage blocking, and the pressing is to fix it by tightening multiple bolts and nuts in sequence, that is, a single set of bolts and nuts cannot be tightened at one time, and can only be tightened a small section first, and then the other set is tightened a small section. After all the tightening is completed once, a second tightening is performed, and this reciprocating process is used to achieve complete tightening of all. In order to simplify this step and achieve the purpose of further improving the efficiency of gas pipeline leakage remediation, a gas pipeline leakage remediation pipeline is provided.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 3 In an embodiment of the utility model, a gas pipeline leakage remediation pipeline includes a remediation kit 1 composed of a C-type sleeve 101, a C-type rubber sleeve 102, a first fixing plate 103, a second fixing plate 104, a fixing screw 105, and a fixing side plate 106. The C-type rubber sleeve 102 is adhesively fixed to the inner side of the C-type sleeve 101, the first fixing plate 103 and the second fixing plate 104 are symmetrically fixed to the outer sides of the two ends of the C-type sleeve 101, the fixing screw 105 and the fixing side plate 106 are respectively fixed to the outer sides of the second fixing plate 104 and the first fixing plate 103, and a quick-install component 2 is arranged on the outer side of the fixing screw 105. The quick-install component 2 is used to realize the mutual tightening operation of the first fixing plate 103 and the second fixing plate 104, and is used to provide an extrusion force for pressing the C-type sleeve 101 against the outer side of the gas pipeline;

[0027] The quick-install assembly 2 includes a tensioning unit and a linkage unit. The tensioning unit is used to realize the mutual tensioning of the first fixing plate 103 and the second fixing plate 104. The linkage unit assists the tensioning unit in performing the tensioning operation, thereby improving the working efficiency of the tensioning operation of the tensioning unit.

[0028] The tensioning unit includes an L-shaped card 201, a through hole 202, a T-shaped solid tube 204, and a nut 205;

[0029] The through holes 202 are symmetrically arranged at the bottom of the L-shaped card 201 and penetrate to the top of the L-shaped card 201. The L-shaped card 201 is sleeved on the outside of the two fixing screw rods 105 through the two through holes 202. The bent portion of the L-shaped card 201 is clamped at the edge of the first fixing plate 103.

[0030] The T-shaped solid tube 204 is fixed on the top of the L-shaped card 201 and is located outside the through hole 202. The nut 205 is rotatably sleeved on the outside of the T-shaped solid tube 204. The T-shaped solid tube 204 is threadedly connected with the fixed screw 105. The tightening of the T-shaped solid tube 204 and the fixed screw 105 is used to realize the pulling of the first fixing plate 103 by the L-shaped card 201, and then realize the operation of pulling the first fixing plate 103 and the second fixing plate 104 closer to each other.

[0031] The linkage unit includes a rotating hole 203, a driven gear 207, a linkage gear 208, a convex column 209, and a polygonal block 210;

[0032] The rotation hole 203 is opened in the middle of the bottom of the L-shaped card 201 and penetrates to the top of the L-shaped card 201. The rotation hole 203 is distributed between the two through holes 202;

[0033] The convex column 209 passes through the rotating hole 203 from the bottom of the L-shaped card 201 to the top of the L-shaped card 201 and is fixedly connected to the linkage gear 208. The driven gear 207 is fixed to the outside of the nut 205, and the two driven gears 207 are meshed with the linkage gear 208. The linkage gear 208 drives the two driven gears 207 to rotate synchronously to realize the synchronous rotation of the two nuts 205. The polygonal block 210 is fixed at the top center of the linkage gear 208 for an external tool to be sleeved to rotate the linkage gear 208.

[0034] The spiral directions of the outer wall thread grooves of the two fixed screw rods 105 are in opposite states, and the inner wall threads of the two nuts 205 match the thread grooves of the two fixed screw rods 105 respectively.

[0035] In this embodiment: it should be supplemented that: the C-shaped sleeve 101 is formed by stamping a metal plate, and the first fixing plate 103, the second fixing plate 104, the fixing screw rod 105, and the fixing side edge 106 are solidified by welding;

[0036] When remediating the gas pipeline leakage, the L-shaped card 201 is sleeved on the outside of the two fixed screws 105 through the two through holes 202. When the fixed screw 105 is in contact with the nut 205, an external tool (such as an electric wrench) is sleeved on the polygonal block 210 and rotated. At this time, the linkage gear 208 rotates and drives the two driven gears 207 to rotate synchronously in opposite directions. The two driven gears 207 respectively drive the two nuts 205 to rotate, so that the nuts 205 and the fixed screw 105 are screwed tightly, thereby realizing the connection between the L-shaped card 201 and the fixed screw 105;

[0037] After the initial connection between the L-shaped card 201 and the fixed screw rod 105, the C-shaped sleeve 101 can be sleeved on the outside of the gas pipeline by pulling the C-shaped sleeve 101 to open its opening and then sleeve it on the outside of the gas pipeline. Then, the L-shaped card 201 is pulled to tighten the C-shaped sleeve 101 and bring the L-shaped card 201 close to the first fixed sheet 103. Finally, the bent portion of the L-shaped card 201 is clamped on the edge of the first fixed sheet 103. At this time, the fixed screw rod 105 is located between the two fixed side plates 106 (the fixed side plates 106 are used to locate and limit the position of the fixed screw rod 105).

[0038] Then, the polygonal block 210 is rotated again by an external tool, so that the two nuts 205 are tightened synchronously with the two fixing screws 105. At this time, the L-shaped card 201 pulls the first fixing plate 103 closer to the second fixing plate 104, so that the C-shaped sleeve 101 is tightened, and the C-shaped sleeve 101 squeezes the C-shaped rubber sleeve 102, so that the C-shaped rubber sleeve 102 is deformed and closely fits the outside of the gas pipeline, thereby achieving the plugging of the gas pipeline leakage.

[0039] Compared with the traditional operation of tightening multiple nuts step by step, the synchronous tightening of the two nuts 205 has a faster sealing efficiency and the overall operation is more convenient and efficient.

[0040] Please refer to Figures 1 to 3 A polygonal barrel block 206 is fixedly connected to the top of the nut 205 , and is used for an external tool to be sleeved on the polygonal barrel block 206 to rotate the nut 205 .

[0041] In this embodiment, the polygonal barrel block 206 can be rotated by an external tool to realize synchronous rotation of the two nuts 205, thus making the sealing operation more flexible.

[0042] Please refer to Figures 2-3 The bottom of the through hole 202 is a bell-mouth structure, the diameter of the bell-mouth bottom is larger than the outer diameter of the fixed screw 105, and the top diameter of the through hole 202 and the inner diameter of the T-shaped solid tube 204 match the outer diameter of the fixed screw 105.

[0043] In this embodiment, the horn structure of the through hole 202 enables the through hole 202 to complete the docking operation with the fixed screw rod 105 more quickly, making the overall use of the device more convenient.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
