[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A natural gas pipeline leak plugging device includes a card plate 1, which is designed to be arched. A fixing groove is penetrated at the side wall of the card plate 1, and a placement tube 4 is arranged in the fixing groove. A sealing device is penetrated at the upper end of the placement tube 4. The sealing device includes an internal thread penetrated at the inner wall of the placement tube 4, and a rotating screw 3 is threadedly connected at the tube mouth of the placement tube 4. The placement tube 4 is filled with leak-proof mud. One end of the rotating screw 3 located in the placement tube 4 is rotatably connected to a sealing plate, and a docking device is fixedly connected at the lower end of the placement tube 4 at a corresponding position. The docking device includes a conical disk 11 fixedly connected to the lower end of the placement tube 4, an inner groove is penetrated in the conical disk 11 and is connected to the placement tube 4, and an opening is penetrated at the lower end of the conical disk 11.

[0021] Among them, sliding grooves are set through the opposite side walls of the card plate 1, and positioning devices are set through the two sliding grooves. The positioning device includes an insertion rod 2 slidably set in the sliding groove, the upper end of the insertion rod 2 is fixedly connected to a striking plate, and the lower end of the insertion rod 2 is designed with a pointed head.

[0022] Specifically, connecting rods 5 are fixedly connected to the opposite side walls of the clamping plate 1, and fixing devices are slidably sleeved on the two connecting rods 5. The fixing devices include a sleeve 6 slidably sleeved on the side walls of the connecting rod 5, and a connecting ring is fixedly connected to the lower end of the sleeve 6. The connecting ring is composed of a first half ring 8 and a second half ring 10. The first half ring 8 and the second half ring 10 are connected by two connecting bolts 9. A fixing screw 7 is penetrated through the side wall of the sleeve 6, and the tail end of the fixing screw 7 is threadedly connected to the port of the connecting rod 5.

[0023] After the leak is found, the operator first aligns the clamping plate 1 and the placement tube 4 with the clamping plate 1, and then rotates the corresponding rotating screw 3 to allow the sealing glue filled in the placement tube 4 to overflow downward through the conical disk 11. The sealing plate arranged at the contact position between the sealing glue and the rotating screw 3 can prevent the sealing glue from overflowing upward along the thread. The sealing glue overflowing through the conical disk 11 can be directly connected to the leak point to achieve the effect of sealing the leak. At the same time, the operator can knock the insertion rods 2 on both sides into the ground for fixing, which can avoid falling off and tilting. After that, the operator fixes the device to the natural gas pipeline through the connecting rings on both sides to complete the overall fixation.

[0024] For the air leakage point located at the lower side of the pipeline, the other components except the insertion rod 2 and the card plate 1 can be reversed for docking, and the card plate 1 remains as it is to prevent rainwater from accumulating at the air leakage point.

[0025] The above description 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.
