Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline leakage detection, especially to the field of real-time pressure detection of urban water supply pipelines. Background Art
[0002] Underground water pipes are a crucial component of urban underground pipelines, and their internal quality directly impacts residents' quality of life. With the rapid development of urban construction and the increasing demand for water supply, pipe layouts are becoming increasingly complex and dense. Long construction times, low quality standards, and increasing aging of pipelines contribute significantly to water leakage crises. Existing technologies typically employ two methods: external inspection and internal inspection. External inspection uses ground-based acoustic frequency acquisition to detect leaks, while internal inspection typically involves endoscopy and pipeline robotics.
[0003] Pipeline inspection robots are capable of moving within pressurized water pipelines and detecting leaks in real time. Prior art pipeline inspection robots are primarily driven by fluid or wheels. Wheel-driven robots are only suitable for use in pipelines with low water levels and large diameters, and are ineffective in pipelines with sustained high water flow. Fluid-driven robots utilize the pressure differential generated by the fluid flowing within the pressure pipeline on both sides of the paramotor to drive the robot. This simple drive system allows the robot to inspect the entire pipeline surface along the direction of water flow.
[0004] Therefore, it is necessary to design a fluid-driven pipeline inspection robot to perform regular inspection and maintenance on these pipelines. Summary of the Invention
[0005] In order to reduce the cost of using pipeline robots, improve work efficiency and adapt to different scenarios, the utility model provides a pipeline inspection robot that can perform real-time leak detection on pipelines of various diameters and continuous high flow rates.

The traction assembly is installed in the front end annular groove of the robot body. The traction assembly drives the robot body to move along the axis in the pipeline. The ground retractable wire device is connected to the rear end sealing cover of the robot body through a cable. The robot body is equipped with an environmental collection device for leak detection in pressurized water supply pipelines.
[0008] Furthermore, the robot body includes a front sealing cover, a tube body, and a rear sealing cover, and the tube body is respectively connected to the front and rear sealing covers through straight pipe threads.
[0009] Furthermore, O-ring grooves are provided at the threads of the front and rear sections of the tube body.
[0010] Furthermore, the traction assembly includes a traction parachute wound around the annular groove at the front end of the robot body, and a fixing rope installed on the robot body, and the fixing rope is located in the annular groove at the front end.
[0011] Furthermore, the environment collection device includes an audio collection device.
[0012] Furthermore, the environment acquisition device includes an image collection device, and the front sealing cover is also provided with an annular groove for installing a lighting device.
[0013] Furthermore, the lighting device is provided in plurality, and the plurality of lighting lamps are arranged around the image collecting device.
[0014] Furthermore, the rear end sealing cover is provided with a circular through hole.
[0015] Furthermore, the cable is a zero-buoyancy cable.
[0016] Furthermore, the ground wire-reeling device is an electric wire-reeling device, and the wire-reeling device is connected to the robot body via a cable.
[0017] In summary, the present invention has at least one of the following beneficial technical effects:
[0018] 1. By adopting a fluid drive method and replacing the complex wheel drive mechanism with a traction parachute, the robot structure is greatly simplified, the space occupied by the robot is reduced, and the adaptability of the inspection robot to narrow pipe diameters is improved.
[0019] 2. The robot body adopts pipe thread connection and cooperates with O-ring to achieve the sealing effect of the robot body under a certain water pressure.
[0020] 3. Through the use of zero-gravity cables, the effective detection distance of the inspection robot in the pipeline is greatly enhanced.
[0021] 4. Through the setting of image acquisition device, audio acquisition device and lighting device, the leakage point is judged by comprehensively considering the leakage point noise situation and the leakage point image in the pipeline, which greatly improves the judgment accuracy.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0029] A water supply pipeline inspection robot is characterized in that a robot transceiver tube enters and exits the pipeline to be inspected, and a traction component is provided at the front end of the robot.
[0030] like Figure 1 As shown in the figure, a robot used for leak detection in water supply pipes includes a robot body 1, a traction component 2, a zero-buoyancy cable 3, and a ground-based reeling device 4. The reeling device adopts an electric cable reeling method. The reeling device is connected to the robot body through an underwater zero-gravity cable and is equipped with an underwater zero-buoyancy cable 3. The cable contains multiple independent cables, which are responsible for power supply and data transmission of the robot body respectively. Figure 2 As shown, the robot body 1 is connected to the front and rear end covers 11 and 15 and the tube body 13 by straight pipe threads 12 and 14, and O-rings are used as sealing units to seal the front and rear end covers and the tube body.
[0031] like Figure 3 As shown, the robot body 1 is provided with an environment collection device for observing the internal conditions of the pipeline, which includes an image collection device 21, an audio collection device 22, and a lighting device 31. Multiple LED lighting lamps arranged around the camera can evenly illuminate the inside of the pipeline. The camera unit can obtain image information of the inner wall of the pipeline. The audio collection device samples the noise of the pipeline leakage point and transmits the image and audio signal to the ground equipment in real time through the cable, so that the staff can comprehensively judge the leakage point situation and accurately locate the leakage point in combination with the cable meter mark.
[0032] like Figure 1As shown, the robot body is provided with a traction component 2 for driving the robot body 1 to move in the pipeline. The traction component includes a traction parachute, a traction parachute frame, and a connecting device. The traction parachute frame has a certain elasticity for adjusting the force applied to the traction parachute. When the water flow in the pipeline flushes the parachute at a certain speed, different pressures are generated in front and behind the parachute. The pressure difference drives the robot body to move along the pipeline in the direction of the water flow, thereby realizing the movement of the robot body.
[0033] The implementation principle of this embodiment is as follows: During actual use, the robot body enters the water supply pipe through the transceiver tube. The pipeline water flow flushes the traction parachute to drive the robot forward. The underwater zero-buoyancy cable is equipped to reduce the burden of robot movement. After the robot enters the pipe, the image and audio collection device begins to operate. The lighting device provides a field of view for the camera. The visual and acoustic signals in the pipe are transmitted to the ground workstation in real time via the cable. The cable transceiver pays out the line to send the robot deep into the pipe, while simultaneously determining whether there are any leaks along the way. After the inspection is completed, the ground transceiver recovers the cable and robot, and the robot is removed through the transceiver tube.
