[0002] Drainage network is an important part of urban construction projects. It is for better drainage and flood discharge in urban areas and environmental protection. The drainage network must be rationalized and timely drainage must be ensured. Most of the drainage networks are built underground, so it is also necessary to locate the drainage network for repair and maintenance projects. The silt and debris inside the drainage network need to be removed in time to prevent the drainage network from being blocked.
[0003] The drainage network is crisscrossed underground and is used for urban drainage work. It is inevitable that the drainage network will be damaged during use. In the case of some minor damage, the existing technical method generally repairs the damaged position inside the drainage pipe through a repair device, that is, a fiber cloth with resin is sent to the damaged position by a traveling vehicle in the pipe, and then the airbag is inflated so that the airbag sticks the fiber cloth with resin to the damaged position to repair the damaged position. However, it is found in use that the wheel group of the existing traveling vehicle is generally fixed in position and can only be operated for one type of drainage pipe. Therefore, it is difficult to adjust for drainage pipes of different sizes, resulting in a relatively simple use. If the wheel group is replaced, the corresponding operation steps and operation complexity will be increased, affecting the progress of damage repair.

DETAILED DESCRIPTION
[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0023] refer to Figure 1 and Figure 2, including a side plate 1 and an inflatable bag 2, the side plates 1 are respectively arranged on the two end surfaces of the inflatable bag 2, the inflatable bag 2 is an existing component and is not described here. A mounting seat 3 is arranged on the side plate 1, and a rotating extrusion member 4 is rotatably connected to the mounting seat 3. A rotating bearing is fixed to the inner side of the mounting seat 3. The mounting seat 3 is an annular member for fixing the rotating bearing. The rotating extrusion member 4 is rotatably connected to the mounting seat 3 through the rotating bearing. The rotating extrusion member 4 includes a rotating tube 8, which is fixed on the inner wall of the rotating bearing. An extrusion disk 9 is fixedly sleeved on the side of the rotating tube 8. The rotating tube 8 rotates through the rotating bearing to drive the extrusion disk 9 to rotate synchronously. The side of the extrusion disk 9 is provided with three sets of arc-shaped recesses The side of the extrusion disc 9 away from the side plate 1 is provided with a handle 11, which is convenient for manually rotating the extrusion disc 9. During operation, when the positioning assembly 5 is away from the extrusion disc 9, the handle 11 is first rotated, and the handle 11 will drive the extrusion disc 9 to rotate. The extrusion disc 9 realizes self-rotation through the rotating tube 8 and the rotating bearing. The rotation of the extrusion disc 9 will drive the position of the arc groove 10 on the side to change to squeeze the adjusting wheel assembly 7, so that it wants to extend outward or shrink inward. It should be noted that when one end of the adjusting wheel assembly 7 is located at the deepest point in the arc groove 10, the shrinkage range of the adjusting wheel assembly 7 is the smallest, and after the adjusting wheel assembly 7 is moved out of the arc groove 10, the outward extension range of the adjusting wheel assembly 7 is the largest;
[0024] refer to Figure 1 and Figure 3The surface of the side plate 1 is located at the position inside the rotating extrusion member 4 and the mounting seat 3, and a positioning component 5 is provided. The positioning component 5 mainly positions the rotation position of the extrusion disk 9 to stabilize it at the desired position. The positioning component 5 includes a positioning shaft 12, which is fixed to the surface of the side plate 1, and the positioning shaft 12 is located on the inner side of the rotating tube 8. The surface of the positioning shaft 12 is movably sleeved with a positioning block 13 that fits the inner wall of the rotating tube 8. A threaded rod 14 is fixed to the side of the positioning shaft 12 away from the side plate 1, and the positioning block 13 is away from the side plate 1. One end of the side plate 1 extends to the position of the threaded rod 14, and a positioning nut 15 is threadedly sleeved on the surface of the threaded rod 14. One side of the positioning nut 15 is movably fitted on the surface of the positioning block 13. The inflation nozzle 6 is arranged at the end of the threaded rod 14 away from the positioning shaft 12. The positioning shaft 12, the side plate 1 and the threaded rod 14 are provided with air holes to connect the inflatable bag 2 with the inflation nozzle 6. The inflation nozzle 6 is an existing component used to inflate the inflatable bag 2. It will not be described here. The positioning block 13 is a conical block, and the inner wall shape of the rotating tube 8 is similar to that of the positioning block. The shapes of the positioning blocks 13 match each other, so that the spacing between the positioning blocks 13 and the inner wall of the rotating tube 8 is gradually reduced under extrusion, and the friction force is increased to improve the positioning effect. The positioning shaft 12 is a square shaft, and the inner wall shape of the conical block matches the shape of the positioning shaft 12. In this way, the positioning block 13 only moves on the positioning shaft 12 and cannot rotate by itself, so as to position the extrusion disk 9 during extrusion, and the inner wall of the rotating tube 8 and the side of the conical block are both embedded with a friction layer 16, which is used to increase the friction between the positioning block 13 and the inner wall of the rotating tube 8. The friction force greatly improves the positioning effect. During operation, the extrusion plate 9 is rotated to the desired position, and then the positioning nut 15 is rotated to move it toward the rotating tube 8. The movement of the positioning nut 15 squeezes the positioning block 13, so that the positioning block 13 fits tightly with the inner wall of the rotating tube 8, and the friction force at this position is increased by the added friction layer 16, thereby realizing the positioning of the rotating tube 8. After the rotating tube 8 is positioned, the extrusion plate 9 is positioned, so that the extrusion plate 9 is stabilized in the position after rotation, and is not easy to move by itself, thereby improving the stability of the extrusion plate 9;
[0025] refer to Figure 1 , Figure 3 and Figure 4The mounting seat 3 and the rotating extrusion member 4 are movably sleeved on the surface of the positioning assembly 5, and the positioning assembly 5 is provided with an inflating nozzle 6. The surface of the side plate 1 is located outside the extrusion member and is provided with an adjusting wheel assembly 7 for adjusting the range of motion of the roller 19. One end of the adjusting wheel assembly 7 is attached to the outer side of the rotating extrusion member 4. The number of the adjusting wheel assemblies 7 is three groups. The three groups of adjusting wheel assemblies 7 are distributed in a ring array with the positioning shaft 12 as the axis on the outside of the rotating extrusion member 4. The three points have stability, so that they can better move on the inner wall of the drain pipe. The adjusting wheel assembly 7 includes The positioning tube seat 17 and the adjusting rod 18 are included. The positioning tube seat 17 is fixed on the surface of the side plate 1 and close to the outer side of the side plate 1. The adjusting rod 18 moves inside the positioning tube seat 17. The adjusting rod 18 is a square rod. The shape of the inner wall of the positioning tube seat 17 matches the surface shape of the adjusting rod 18. In this way, when adjusting, the adjusting rod 18 can only move along the positioning tube seat 17 on the positioning tube seat 17 and cannot rotate by itself, so that the roller 19 is stable in adjustment and use. The roller 19 is arranged on the side of the adjusting rod 18 away from the extrusion plate 9, and the other end of the adjusting rod 18 is arranged with an adjusting block 21, the adjusting block 21 is movably fitted on the side of the extrusion disk 9, and the two sides of the adjusting block 21 are provided with inclined cutouts 22. The surface of the adjusting rod 18 is located between the adjusting block 21 and the positioning tube seat 17, and a spring member 20 is movably sleeved. The two ends of the spring member 20 are respectively fitted on the opposite surfaces of the adjusting block 21 and the positioning tube seat 17. Under the action of the spring, the spring will squeeze the adjusting block 21, so that the adjusting block 21 is stably fitted on the side of the extrusion disk 9. In this way, the adjusting block 21 will drive the adjusting rod 18 and the roller 19 to be stable together, and it is not easy to move freely to the outside. During operation, when the extrusion The rotation of the disk 9 will squeeze the adjusting block 21, and the squeezing of the adjusting block 21 will drive the adjusting rod 18 to move. The movement of the adjusting rod 18 will drive the rollers 19 to extend outward or contract inward to change the size of the movable range of the three groups of rollers 19 and thus match drain pipes of different sizes, thereby achieving the effect of changing the movable range by moving the adjusting wheel assembly 7. It should be noted that when the adjusting block 21 is located at the deepest part of the arc-shaped groove 10, the contraction range of the three groups of rollers 19 is the smallest. After the three groups of rollers 19 move out of the arc-shaped groove 10, the three groups of rollers 19 extend outward, so that the range of the three groups of rollers 19 is the largest.
