[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a non-excavation pipeline 1 inner wall repair device, including a pipeline 1, the outer surface of the pipeline 1 is provided with a positioning structure 2, the positioning structure 2 includes a first positioning sleeve 201, the outer surface of the first positioning sleeve 201 is plugged and connected with the second positioning sleeve 202, the outer surface of the second positioning sleeve 202 is plugged and connected with the third positioning sleeve 203, the outer surface of the third positioning sleeve 203 is plugged and connected with a positioning module 204, the outer surfaces of both sides of the positioning module 204 are fixed with fixing mechanisms 205, the outer surface of the positioning module 204 is provided with a calibration structure 3, and the calibration structure 3 includes a receiving module 301.

[0025] In this embodiment, the installation of the positioning structure 2 is mainly through the positioning module 204 and the fixing mechanism 205. The fixing mechanism 205 on the outer surface of the positioning module 204 is used to fix it to the outer surface of the pipe 1 to achieve a fixing effect, while the disassembly is the reverse operation. For pipes 1 of different sizes, the inner wall of the positioning module 204 can be enlarged or reduced by installing the first positioning sleeve 201 or the second positioning sleeve 202 and the third positioning sleeve 203 to achieve the effect of installation for pipes 1 of different sizes.

[0026] Example 2

[0027] like Figure 1-5As shown, a docking groove 302 is provided at the center of the outer surface of one side of the receiving module 301, and a docking plate 303 is fitted and extruded inside the docking groove 302, and a receiving block 304 is fixed to the outer surface of one side of the docking plate 303. A first threaded layer 305 is provided on the outer surface of one side of the receiving block 304, and the outer surface of the first threaded layer 305 is connected to the second threaded layer 306 through a thread, and an auxiliary calibration module 307 is provided on the outer surface of one side of the second threaded layer 306. The first positioning sleeve 201 is arranged on the outer surface of the pipeline 1, and the first positioning sleeve 201 and the pipeline 1 are fitted and connected. There are two receiving modules 301 in total, and each of them is arranged in a group on the outer surface of the positioning module 204 and arranged opposite to each other.

[0028] In this embodiment, the calibration structure 3 is mainly used to calibrate the filling material, and the calibration effect is mainly achieved through the auxiliary calibration module 307, wherein the installation of the calibration structure 3 is mainly achieved by holding the receiving block 304, aligning the docking plate 303 on the outer surface of one side thereof with the docking groove 302 and inserting the same so that the two are fit and squeezed together, and then holding the auxiliary calibration module 307 to align the first threaded layer 305 on the outer surface of one side thereof with the second threaded layer 306 and rotate the same so that the two are threadedly connected to complete the installation of the calibration structure 3, and the removal can be done by the reverse operation.

[0029] Working principle:

[0030] like Figure 1-5 As shown, in actual use, the pipeline 1 mainly plays a role in the transmission of water resources, or gas and wastewater, etc. The pipeline 1 facilitates the transmission effect and can save a lot of manpower and material resources, and the positioning structure 2 mainly plays a role in positioning the calibration structure 3. The positioning structure 2 fixes itself on the outer surface of the pipeline 1 and is positioned and connected with the calibration structure 3 through its outer surface, and the calibration structure 3 mainly plays a role in calibration when the pipeline 1 is repaired;

[0031] It should be noted that when the pipeline 1 needs to be repaired, the positioning structure 2 needs to be positioned on the outer surface of the pipeline 1 first, and the positioning is mainly achieved through the positioning module 204 and the fixing mechanism 205. The first positioning sleeve 201 or the second positioning sleeve 202 and the third positioning sleeve 203 can be targeted or reduced according to the circumference of the pipeline 1. The installation of the first positioning sleeve 201, the second positioning sleeve 202 and the third positioning sleeve 203 is mainly achieved by aligning the concave and convex blocks on the outer surface of the first positioning sleeve 201 with the concave and convex grooves of the next positioning sleeve, and the two are connected by plugging, so as to achieve the installation effect. It should be noted that when installing the first positioning sleeve 201, the second positioning sleeve 202 and the third positioning sleeve 203, the third positioning sleeve 203 needs to be installed first, followed by the second positioning sleeve 202, and finally the first positioning sleeve 201. Then, the positioning module 204 is tightened and fixed to the outer surface of the pipeline 1 through the fixing mechanism 205. It should be noted that the first positioning sleeve 201 or the second positioning sleeve 202 and the third positioning sleeve 203 are all made of rubber and have a certain anti-slip effect. When the positioning structure 2 is installed, the calibration structure 3 can be installed. The calibration structure 3 needs to be installed by holding the receiving block 304, aligning the docking plate 303 on the outer surface of one side of the receiving block 304 with the docking groove 302, so that the docking plate 303 and the docking groove 302 are fit and squeezed and connected. After the two are connected, the auxiliary calibration module 307 is held by hand, and the first thread layer 305 on the outer surface of one side of the auxiliary calibration module 307 is aligned with the second thread layer 306 and rotated so that the two threads are connected by threads. At this point, the installation of the calibration structure 3 is completed, and the disassembly can be done in the opposite way. It should be noted that the auxiliary calibration module 307 mainly calibrates the range line through its large diameter. The filling material touches the inner wall of the auxiliary calibration module 307 when extending, and the auxiliary calibration module 307 will guide the filling material into the pipeline 1 through its inner wall.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
