[0002] Drainage pipes are in long-term use, so soil subsidence or heavy road pressure may cause the pipes to rupture, so they need to be repaired. However, since the pipes are buried deep, it is difficult to expose the damaged parts of the pipes for repair by excavation, which makes the repair of underground drainage pipes more difficult.

[0003] The Chinese invention patent with publication number CN105465551B disclosed a flexible and adaptive supported in-pipeline inspection robot on January 25, 2016, including a flexible and adaptive support mechanism, a driving mechanism, a detection mechanism and a camera mechanism; the camera mechanism is installed at the front end of the flexible and adaptive support mechanism; the flexible and adaptive support mechanism is connected to the driving mechanism to ensure that the robot has the ability to automatically adapt to the reducer, obstacles or bends when moving in the pipeline; the detection mechanism is installed on the driving mechanism, and when the robot is performing inspection operations in the pipeline, the probe part in the detection mechanism is in full contact with the inner wall of the pipeline. The present invention realizes the flexible adaptation of the robot to the pipeline and the modularization of the supported in-pipeline robot, enhances the robot's walking ability in the pipeline, and also facilitates the maintenance of such robots; the present invention also realizes that the in-pipeline inspection robot is equipped with non-destructive testing equipment, thereby improving the detection ability of problematic pipelines.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing pipeline inspection robots have a complex structure and cannot adapt to sewer pipes with a larger diameter range, which makes their use scope small. In addition, they are large in size and weight, cannot enter small-diameter pipes for inspection, and do not have a smearing and repair function. Utility Model Content

The gap in the sewer pipe can be repaired through the repair unit, which solves the problem that the existing sewer pipe detection device cannot adapt to sewer pipes with small diameters.

[0025] The repair unit includes a fastener 6; the fastener 6 is threadedly inserted into the fixed frame 1; a sleeve 7 is sleeved on the fastener 6; a main gear 8 is fixedly connected to the sleeve 7; a sub-gear 9 is meshedly connected to the main gear 8; a second motor 10 is fixedly connected to the sub-gear 9; the second motor 10 is fixedly connected in the fixed frame 1; a first push rod 11 is fixedly connected to the sleeve 7; a brush roller 20 is fixedly connected to the movable end of the first push rod 11; a hose 19 is connected and fixedly connected to the brush roller 20; when working, the sub-gear 9 is driven to rotate by the second motor 10 being energized and controlled to rotate, thereby driving the main gear 8 and the sleeve 7 to rotate, thereby driving the first push rod 11 fixed on the sleeve 7 to rotate, thereby driving the brush roller 20 fixed at the end to rotate around the damaged part of the sewer, and then the hose 19 is externally connected to the repair liquid for spraying, so as to realize all-round coating to form a protective layer, so that the local position of the sewer pipe is repaired, solving the problem of large size, heavy weight and complex structure of the existing pipeline repair robot.

[0026] The lower end of the hose 19 is connected to and fixedly connected with a storage box 18; a delivery pump is fixedly connected inside the storage box 18; when working, the repair liquid in the storage box 18 can be driven by the delivery pump, so that repair can be carried out without external repair liquid, thereby reducing the coordination of repair-related equipment and making it more convenient to repair the pores in the sewer.

[0027] The gap of the fixed frame 1 is greater than or equal to twice the thickness of the movable plate 3; when working, the left and right displacement of the two movable plates 3 is limited by the fixed frame 1 so that the center position remains unchanged, and the roller 4 can approach the upper and lower ends of the sewer pipe, thereby supporting stable movement in the sewer.

[0028] The fixed frame 1 and the movable plate 3 are made of engineering plastics. When working, the fixed frame 1 and the movable plate 3 made of engineering plastics make the whole body lighter, reduce the power demand of the motor, and make the whole body more convenient to carry.

The gap of the sewer pipe can be repaired through the repair unit, which solves the problem that the existing sewer pipe detection device cannot adapt to sewer pipes with small diameters; the second motor 10 is powered on to control the rotation to drive the secondary gear 9 to rotate, thereby driving the main gear 8 and the sleeve 7 to rotate, thereby driving the first push rod 11 fixed on the sleeve 7 to rotate, thereby driving the brush roller 20 fixed at the end to rotate around the damaged part of the sewer, and then the hose 19 is externally connected to the repair liquid for spraying, thereby realizing all-round coating to form a protective layer, so that the local position of the sewer pipe is repaired, solving the problem that the existing pipeline repair robot is large in size, heavy in weight and complex in structure.
