[0028] Example:

[0029] Please see Figure 1-5 A gas pipeline emergency repair and sealing component includes a gas pipe body 1, and a sealing mechanism 2 is movably connected to the inner surface of the gas pipe body 1.

[0030] This solution uses the sealing mechanism 2 to seal some continuously ventilated gas pipe bodies 1, which can effectively prevent large-scale gas leakage and avoid the hidden dangers caused by gas leakage.

[0031] Please see Figure 2-5 The sealing mechanism 2 includes a positioning tube 21, a sealing ring 22 fixedly connected to the inner surface of the positioning tube 21, a connecting component 23 fixedly connected to the outer surface of the positioning tube 21, a fixing component 24 fixedly connected to the upper part of the connecting component 23, and a blocking component 25 threadedly connected inside the connecting component 23.

[0032] The fixing component 24 includes a positioning plate 241. An air pump 242 is fixedly connected to the upper end of the positioning plate 241. An inflation tube 243 is fixedly connected to the output end of the air pump 242. An airbag 244 is fixedly connected to the lower end of the inflation tube 243. The inner surface of the airbag 244 is fixedly connected to the outer surface of the positioning tube 21.

[0033] The connecting assembly 23 includes a connecting plate 231, the inner surface of the connecting plate 231 is fixedly connected to the outer surface of the positioning tube 21, the upper end of the connecting plate 231 is provided with a positioning groove 232, the inner surface of the positioning groove 232 is fixedly connected to the outer surface of the positioning plate 241, the lower end of the connecting plate 231 is provided with a tube groove 233, the upper end of the connecting plate 231 is fixedly connected with a support frame 234, and the upper end of the support frame 234 is fixedly connected with an internally threaded tube 235.

[0034] The plugging assembly 25 includes a handle 251, with a lead screw 252 fixedly connected to the lower end of the handle 251. The outer surface of the lead screw 252 is threadedly connected to the inner surface of the internally threaded tube 235, and the outer surface of the lead screw 252 is threadedly connected to the inner surface of the support frame 234. A limit plate 253 is fixedly connected to the outer surface of the lead screw 252, and a rubber plug 254 is fixedly connected to the lower end of the lead screw 252. The diameter of the rubber plug 254 is slightly larger than the diameter of the positioning tube 21.

[0035] This solution involves inserting the positioning tube 21 into the gas pipe body 1, activating the air pump 242, and inflating the airbag 244 through the inflation tube 243. The airbag 244 is then inflated by the air pump 242 and presses tightly against the inner wall of the gas pipe body 1, thus fixing the entire sealing assembly to the gas pipe body 1. Then, the handle 251 is rotated, causing the lead screw 252 to rotate on the inner surface of the internally threaded tube 235. As the rotation continues, the lead screw 252 moves downwards along the internally threaded tube 235, allowing the rubber plug 254 to be squeezed into the inner surface of the positioning tube 21. With continued rotation of the handle 251, the rubber plug 254 rotates downwards along the inner surface of the positioning tube 21. When the rubber plug 254 abuts against the upper end of the sealing ring 22, it engages with the sealing ring 22, enhancing the sealing performance and effectively preventing gas leakage.

[0036] It should be noted that the specific installation method, circuit connection method and control method of the air pump 242 in this utility model are all conventional designs, and this utility model will not elaborate on them in detail.

[0037] Working principle: During the emergency repair of gas pipelines, it is necessary to use a sealing component to seal some continuously ventilated gas pipe bodies 1. When using the component, it is necessary to first fix the component to the inner surface of the gas pipe body 1, insert the positioning tube 21 into the gas pipe body 1, start the air pump 242, and let the air pump 242 inflate the air bag 244 through the inflation tube 243, so that the air bag 244 is inflated under the action of the air pump 242 and tightly pressed against the inner wall of the gas pipe body 1.

[0038] Then, the handle 251 needs to be rotated so that the lead screw 252 rotates on the inner surface of the internally threaded tube 235 under the action of the handle 251. As the rotation continues, the lead screw 252 will move downward along the internally threaded tube 235, so that the rubber plug 254 can be squeezed into the inner surface of the positioning tube 21 under the action of the lead screw 252. As the handle 251 continues to rotate, the rubber plug 254 will rotate and move downward along the inner surface of the positioning tube 21. When the rubber plug 254 abuts against the upper end of the sealing ring 22, it will cooperate with the sealing ring 22 to enhance the sealing performance, effectively prevent gas leakage, and prevent safety hazards.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
