The expansion assembly 220 is provided with a detection mechanism. The expansion assembly 220 is driven by the cylinder assembly 210 to adhere to the inner wall of the pipeline, so that the expansion assembly 220 is unfolded in the pipeline to form a sealed space with the inner wall of the pipeline for the detection mechanism to work.

[0034] The embodiment is thus arranged, which is suitable for the case that the pipeline has water flow, but the water flow cannot fill the entire pipeline. That is, the walking wheel can travel in the pipeline, the expansion assembly 220 is driven by the cylinder assembly 210 to approach and adhere to the inner wall of the pipeline, and then the expansion assembly 220 is unfolded, so that a sealed space is formed between the expansion assembly 220 and the inner wall of the pipeline. At this time, the water flow outside will not interfere with the detection mechanism, and the detection staff can clearly observe the detection picture of the inner wall of the pipeline through the detection mechanism, without the need to take measures to cut off the flow, thereby reducing the operation difficulty and improving the work efficiency.

[0035] In an embodiment, please refer to Figure 2 and Figure 3The expansion assembly 220 comprises two fan-shaped plates 221 arranged in parallel, the two fan-shaped plates 221 are controlled to approach and move away from each other by the bidirectional telescopic cylinder 228, each fan-shaped plate 221 is provided with an elastically telescopic wheel disc 222 at an outer arc angle, the outer edge of the fan-shaped plate 221 is provided with a convex strip 224, and a water-blocking curtain 225 connected with the corresponding convex strip 224 is arranged between the two fan-shaped plates 221, when the two fan-shaped plates 221 move away to the maximum distance, the water-blocking curtain 225 is completely unfolded, and a sealed space is formed by the inner wall of the pipeline, the fan-shaped plate 221 and the water-blocking curtain 225. The wheel disc 222 is connected with the fan-shaped plate 221 through a connecting support 223, and the connecting support 223 is provided with an elastic element connected with the wheel disc 222.

[0036] In this embodiment, the control body 100 is arranged to move in the pipeline, when the control body 100 moves to a specified position, the expansion assembly 220 is driven to separate from the control body 100 and approach the inner wall of the pipeline by the cylinder assembly 210, in the approaching process, the bidirectional telescopic cylinder 228 acts to separate the two fan-shaped plates 221 and pull open the water-blocking curtain 225, when the distance between the two fan-shaped plates 221 is the maximum, the water-blocking curtain 225 is completely unfolded, at this time, the unfolded water-blocking curtain 225 and the fan-shaped plate 221 are attached to the corresponding inner wall of the pipeline, so that the inner wall of the pipeline, the fan-shaped plate 221 and the water-blocking curtain 225 form a sealed space, the detection mechanism can work, the water flow in the pipeline does not interfere with the detection mechanism, and the detection staff can clearly observe the detection picture of the inner wall of the pipeline without taking measures to cut off the flow, thereby reducing the operation difficulty and improving the work efficiency.

[0037] In an embodiment, referring to Figure 3 and Figure 4 The obstacle cleaning assembly 230 comprises a moving support 236 arranged between the two fan-shaped plates 221, the moving support 236 is slidably connected with the fan-shaped plates 221 on both sides and moves in an arc track by a driving mechanism 2361, the moving support 236 is provided with a guide plate 234, the guide plate 234 is provided with a driving rack 233, the driving rack 233 is meshingly connected with a rotating gear 231 arranged on the inner wall of the fan-shaped plate 221, the rotating gears 231 on the two fan-shaped plates 221 are coaxially connected with an obstacle cleaning roller 232, the rotating outer ring of the obstacle cleaning roller 232 covers the outer arc line of the fan-shaped plate 221 in the front projection plane, the guide plate 234 is provided with a return spring 235 connected with the driving rack 233, and the end of the driving rack 233 is located outside the fan-shaped plate 221 in the initial state. The bristles of the obstacle cleaning roller 232 extend to the outside of the fan-shaped plate 221.

[0038] The embodiment is thus configured. When the observation and detection of the inner wall of the pipeline to be detected is affected by silt or other debris, in the process of the expanded space assembly 220 approaching the inner wall of the pipeline, the end of the driving rack 233 first contacts the inner wall of the pipeline, and then retracts backward as the expanded space assembly 220 continuously approaches, driving the rotating gear 231 to rotate, and then driving the obstacle-removing roller 232 near the outer arc edge of the sector plate 221 to rotate, so that the obstacle-removing roller 232 can clean the inner wall of the pipeline when the expanded space assembly 220 is attached to the inner wall of the pipeline, facilitating the subsequent detection mechanism to clearly observe. When the sector plate 221 is not completely attached to the inner wall of the pipeline, the obstacle-removing roller 232 is already in a rotating state, and the bristles thereon cooperate with the flowing water to remove the silt and debris at the detection position.

[0039] The driving mechanism 2361 can adopt a pull rope and a winding reel. By retracting one side, the obstacle-removing assembly 230 can be controlled to move along the arc of the sector plate 221, so as to align the obstacle-removing roller 232 with the detection position, so that it can cover the entire closed space formed by the sector plate 221 and the water-blocking curtain 225, thereby improving the range of obstacle removal.

[0040] In an embodiment, referring to Figure 3 and Figure 4 , the outer arc edge of the sector plate 221 is provided with a bare arc-shaped air bag 2211, the arc-shaped air bag 2211 is connected with one end of a gas guide pipe 2212 embedded in the sector plate 221, the other end of the gas guide pipe 2212 is provided with a piston rod 2213, the end of the piston rod 2213 is connected with the driving rack 233, and the water-blocking curtain 225 is embedded with a plurality of built-in linear air bags 2251 at both ends, the linear air bags 2251 are connected with the gas guide pipe 2212 through a communication pipe, and when the end of the driving rack 233 is compressed between the two sector plates 221, the arc-shaped air bag 2211 and the linear air bag 2251 are in an inflated state.

[0041] The embodiment is thus configured. When the expanded space assembly 220 approaches and attaches to the inner wall of the pipeline, the driving rack 233 retracts into the closed space, pushing the piston rod 2213 to move, so that the gas in the gas guide pipe 2212 is pushed into the arc-shaped air bag 2211 and the linear air bag 2251. After the expanded space assembly 220 is completely attached to the inner wall of the pipeline, the arc-shaped air bag 2211 and the linear air bag 2251 are in an inflated state, which can enhance the sealing effect and avoid the problem that the water flow continuously affects the detection during the detection process, thereby ensuring the smooth progress of the detection.

[0042] The gas guide pipe 2212 is composed of two hard pipes and a soft pipe. The soft pipe connects the two hard pipes, and the length of the soft pipe can satisfy the movement of the obstacle-removing assembly 230 in the closed space to the extreme positions at both ends, thereby adapting the change of the position of the obstacle-removing assembly 230 in the closed space without affecting the reinforcing sealing effect of the arc-shaped air bag 2211 and the linear air bag 2251.

[0043] In an embodiment, referring to Figure 5 Further comprising a side support assembly 300, the side support assembly 300 comprises support rods 301 arranged on both sides of the body, and the support rods 301 are provided with arc-shaped support plates 302 at the front ends, and the support rods 301 are horizontally turned out and extended.

[0044] In this embodiment, when the water flow in the pipeline is large, after the body 100 moves to the designated position, the support rods 301 are horizontally turned out and extended to drive the arc-shaped support plates 302 to approach and adhere to the inner wall of the pipeline, and the support rods 301 arranged on both sides maintain the body 100 at the current position, keep the stability of the body 100, and further improve the stability during detection.

[0045] Among them, the support rod 301 is a cylinder rod, and one end is rotatably connected with the body 100 and is controlled to rotate by a waterproof motor.

[0046] In an embodiment, referring to Figures 2-4 Further comprising a drain pipe 229 arranged through one side of the fan-shaped plate 221, and provided with a water pump, one end of the drain pipe 229 is a telescopic structure, and after being extended, the end approaches the outer arc edge of the fan-shaped plate 221, and the other end is a bent pipe structure, and the pipe body of the drain pipe 229 located outside the fan-shaped plate 221 extends reversely to the fan-shaped plate 221 by a distance of one or two radii of the fan-shaped plate 221.

[0047] In this embodiment, after the closed space is formed, the accumulated water remaining in the closed space can be discharged through the arrangement of the drain pipe 229, so that the inner wall of the pipeline in the closed space is in a completely exposed state, and efficient detection can be facilitated by the detection mechanism.

[0048] Among them, the telescopic structure of one end of the drain pipe 229 is controlled by a cylinder, so as not to block the movement of the obstacle removing assembly 230.

[0049] In an embodiment, referring to Figure 3 And Figure 4 The detection mechanism comprises a detection camera 227, and the detection camera 227 is provided with a lighting module 2271 around, and the detection camera 227 is arranged through the water-blocking curtain 225, and the connection part is sealed and connected by a sleeve.

[0050] In this embodiment, the picture of the inner wall of the pipeline can be taken by the detection camera 227, and the image can be analyzed by the external analysis equipment, so as to judge the current quality of the inner wall of the pipeline. Through the arrangement of the lighting module 2271, the lighting intensity in the closed space can be enhanced, so that the detection camera 227 can take clearer images and improve the detection precision.

[0051] In an embodiment, referring to Figure 2The cylinder assembly 210 comprises a linear driving cylinder 211 connected with the body 100, the end of the linear driving cylinder 211 is provided with a rotating cylinder 212, the output end of the rotating cylinder 212 is provided with a pushing cylinder 213 which is at an angle of 90° with the rotating cylinder 212, and the end of the pushing cylinder 213 is connected with a telescopic support 226, and the bottom end of the telescopic support 226 is connected with two sector plates 221.

[0052] The embodiment is configured in this way: when the body 100 moves to a specified position, the hollow expanding assembly 220 is driven away from the body 100 by the linear driving cylinder 211, then the hollow expanding assembly 220 is rotated to a specified position by the rotating cylinder 212, and finally the hollow expanding assembly 220 is driven to approach the inner wall of the pipeline and finally attached to the inner wall of the pipeline by the pushing cylinder 213, so that the hollow expanding detection work is completed; when the detection work of a region is completed, the hollow expanding assembly 220 is driven to do circular motion by the rotating cylinder 212 until the detection of the annular line of the specified region of the inner wall of the pipeline is completed, so that the operation is simple and fast, the detection picture is clear, and the detection precision is high.
