[0002] Underground pipelines are pipes laid underground for the transportation of liquids, gases or loose solids. In ancient China, underground drainage pipes made of fired clay were already used. In the Ming Dynasty, when Beijing was the capital, bricks and stone strips were used extensively to build underground drainage pipes. The width is about 1 meter and the height is about 2 meters. There are many types of modern underground pipelines, including circular, elliptical, semi-elliptical, multi-circular, oval, rectangular (single hole, double hole and multi-hole), horseshoe and other cross-sectional forms. They are built with materials such as steel, cast iron, concrete, reinforced concrete, prestressed concrete, brick, stone, asbestos cement, clay, plastic, fiberglass (reinforced plastic) and other materials. Urban underground pipeline maintenance is an indispensable component and requires regular maintenance. The medium circulating in the pipeline is highly corrosive, and the erosion of groundwater and other various reasons have caused leakage, collapse, misalignment and thinning of the pipe wall, resulting in poor circulation of sewage pipes and ground subsidence.

[0003] However, the existing methods of repairing underground pipelines have the following problems: (1) After the existing pipelines are repaired, the coating at the repaired part is in a dark and humid environment for a long time, and the drying and curing effect is very slow, which is prone to secondary damage; (2) The existing repair methods are relatively traditional and require people to enter the manhole for cooperation, and there are a large number of bacteria and toxic gases in the pipelines, which is prone to safety problems. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the invention

The power output end of the motor 13 is connected to the roller 12 and is connected to an electric wire 14. The electric wire 14 is built into the support arm 10. The rear seat 6 of the light chain has the same structure as the front seat 5 of the light chain. A front camera 15 and a lighting lamp are also installed in the middle of the front seat 5 of the light chain. A battery 16 is installed at the tail of the light chain rear seat 6. An aviation socket 17 is installed at the tail of the battery 16 and is connected to the heating lamp 8 through a line. The aviation socket 17 is connected to the cable 3.

[0022] Further improvement, such as Figure 1 As shown: a triangular bracket is installed at the outer end of the winding drum 2, and the triangular bracket includes a horizontally arranged guide plate 18 and a support rod 19 installed obliquely below the guide plate 18. The end of the support rod 19 is movably connected to the winding drum 2 through a hinge, which can achieve the purpose of support and guidance during the process of paying out and reeling in the line.

[0023] Further improvement, such as Figure 1 As shown, a cable groove 20 is horizontally opened on the surface of the guide plate 18, and the cable 3 is arranged in the cable groove 20, so as to facilitate guiding the cable 3.

[0024] Further improvement, such as Figure 3 As shown: the support arm 10 is a two-section structure and includes a rigid connecting rod 21 and a flexible connecting rod 22. The rigid connecting rod 21 is connected to the driving wheel, one end of the flexible connecting rod 22 is integrally formed with the rigid connecting rod 21 and the other end is connected to the base 9. This design makes it easy to adjust the angle of the support arm 10.

[0025] Further improvement, such as Figure 3 As shown: the flexible connecting rod 22 is made of plastic metal material and has a rod-shaped structure. A notch 23 is formed in the middle of the flexible connecting rod 22. The use of plastic metal material facilitates the angle bending of the flexible connecting rod 22 so that the driving wheel fits the inner wall of the pipeline.

[0029] Specifically, two sets of hanging rings 25 are symmetrically installed on both sides of the front camera 15.

[0030] During use: When the repaired part of the pipeline needs to be cured, the opening angle of the support arm 10 is first adjusted according to the inner diameter of the pipeline, so that the driving wheel contacts the inner wall of the pipeline, and the headlight chain 4 is placed in the manhole. The headlight chain 4 uses a battery 16 and a cable 3 to power the driving wheel, so that the headlight chain 4 crawls along the inner wall of the pipeline. During the crawling process, the cable reel 2 synchronously pays out the wire and searches for the repaired part of the inner wall of the pipeline through the front camera 15. The headlight chain 4 stops moving and heats and cures the repaired part through the heating lamp 8, and monitors the heating temperature through the temperature sensor 11 to ensure that the temperature is within a reasonable range.

[0031] Finally, it should be noted that the above description 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 replace some of the technical features therein by equivalents.
