[0046] Example 2

[0047] With reference to Figure 4Unlike the embodiment 1, the top of the connector B15 can be inserted into the inside of the connector A12, and the bottom of the connector A12 is provided with a lower protruding locking member 17 which is inserted into the connector B15.

[0049] The specific operation principle of the application is as follows:

[0050] Referring to Figure 7 When encountering high water flow conditions: remove the blocking pin 44 of the reversing wheel assembly 4, make the robot cable pass through the guide wheel 41, and then insert the blocking pin 44. Slowly put the robot into the detection well, and then slowly put the robot into the detection well. The auxiliary device guide wheel 34 faces the robot side. When the robot enters the high-speed flowing water, it is washed away by the water flow, and a large tensile force is generated on the cable. The auxiliary device guide wheel 34 is tightly pressed against the inspection well wall and slowly moves downward. When the guide wheel 34 moves to the junction of the transverse drainage pipe, it slides into the drainage pipe and is clamped at the junction under the action of the tensile force of the cable in the transverse and longitudinal directions. Artificial does not need to pull or press the quick-change connecting rod 1, which can realize the cable around the reversing wheel stretching, avoiding the risk of scratching and cutting at the junction.

[0051] Referring to Figure 8 When encountering static water and high deposition conditions: the robot relies on its own power to travel, and the tensile force of the cable is small. The bottom of the fork frame 2 is directly inserted into the bottom of the inspection well chamber to realize the stretching and contraction of the cable around the reversing wheel 41.

[0052] Referring to Figure 9 When encountering robot failure conditions: the robot cannot exit the drainage pipe due to failure. Referring to the high water flow, static water and high deposition conditions, the artificial pulls the cable on the well to drag the robot into the inspection well chamber. The auxiliary device guide wheel 34 of the high water flow condition tightly abuts against the inspection well wall to slide out of the flowing water area with the robot.

[0053] And the static water and high deposition conditions can separately or simultaneously lift the auxiliary device and the robot out of the inspection well.

[0054] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
