[0002] The urban drainage pipeline is the important way of excluding urban sewage and rainwater, is also the component part of urban public facilities, and even becomes the infrastructure of urban stable development. However, in the long-term use process, the deposition of scale, silt and other impurities will be produced in the pipeline, and the abrasion thinning of pipe wall, crack, even breakage will be caused due to the long-term scouring of water flow to pipe wall, and the leakage of pipe wall, the loosening of soil outside pipe wall, the formation of cavity phenomenon with the water flow, and the collapse of road surface. And the size of sewer pipe diameter is different, therefore, a multifunctional urban drainage pipeline detection robot is needed for the detection of drainage pipeline, the discovery of internal and external problems of pipeline, the timely cleaning and repair, and the application to different size pipe diameter.

[0003] Through the search, the Chinese patent with publication number CN106439385B discloses a telescopic arm type pipeline detection robot suitable for different size pipe diameter, which comprises a body, a lifting assembly, a CCTV detection assembly and a cavity detection assembly. The lifting assembly comprises a main lifting arm, an auxiliary lifting arm and a lifting driving mechanism. One end of the main lifting arm and the auxiliary lifting arm is hinged to the body, and the other end is hinged to the CCTV detection assembly. The main lifting arm and the auxiliary lifting arm form a parallelogram. Each drive wheel system is hinged to the body through a telescopic arm assembly. The telescopic arm assembly comprises an upper arm and a lower arm. The upper end of the upper arm is hinged to the body, and the lower end is hinged to the upper end of the lower arm. The lower end of the lower arm is hinged to the drive wheel system. A positioning pin or a positioning cover is arranged at each hinge.

[0004] The device enables the CCTV detection assembly to always remain in a horizontal state, can be applied to pipelines of different diameters, and always keeps the contact area of the drive wheel system with the inner wall of the pipeline to be maximum, thereby increasing the adhesion.

[0005] However, the device still has the following problems. The device adjusts the relative distance between the drive wheel system and the body by pulling out the positioning pin and then rotating the upper arm and the lower arm, so as to adapt to pipelines of different diameters. However, in actual use, the relative distance between the drive wheel system and the body is easily adjusted multiple times to make the detection assembly be in the specified position. In this process, the positioning pin needs to be repeatedly inserted and pulled out multiple times, which is complicated to operate and difficult to effectively improve the convenience of using the device.
