Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline detection robot. Background Art

[0002] Pipelines have been widely used in all aspects of life. Pipeline transportation is relatively common in my country, especially in the fields of petroleum, chemical industry, nuclear industry, urban construction, etc. Once the pipeline is corroded, the pipe wall becomes thinner, cracks are likely to occur, causing oil leakage and other problems, posing major safety hazards and economic losses. Therefore, regular inspections of pipelines are required.

[0003] The shortcomings of existing technologies are that, due to the limitations of robot design, the robot has poor adaptability to pipe diameters, and the environment during its movement may be relatively harsh. Some robots find it difficult to adapt to harsh environments, which limits their range of movement. During movement, they may encounter pipe blockages, making it difficult for the robot to continue moving forward, and manual pipe clearing is required, which greatly increases the time and cost required for inspection, making the overall process time-consuming and labor-intensive. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a pipeline detection robot.

[0005] An embodiment of the present utility model provides a pipeline inspection robot, comprising:

[0006] A protective shell, with multiple detection devices fixedly mounted on the outside of the protective shell;

[0007] A vibration structure is installed inside the protective shell, and the vibration structure includes a support plate 1 fixedly installed in the protective shell, a driving motor is fixedly installed on the upper side of the support plate 1, a driving shaft is fixedly installed on the output end of the driving motor, a rotating block is fixedly connected to the outer side of the driving shaft, a hollow shaft is rotatably connected to the side wall of the protective shell, a sliding rod is slidably connected in the hollow shaft, a disc is fixedly installed at one end of the sliding rod, a plurality of spherical sliders are fixedly installed on the side wall of the disc, a support plate 2 is fixedly installed inside the protective shell, two springs 1 are fixedly connected between the support plate 2 and the disc, the other end of the sliding rod is fixedly connected to a striking disk, and a plurality of conical striking blocks are fixedly connected to the side wall of the striking disk.

[0008] Furthermore, a cleaning structure is installed in the protective shell, and the cleaning structure includes a spur gear 1 fixedly sleeved on the outside of the drive shaft, the side wall of the support plate 2 is rotatably connected to the rotating shaft, the outside of the rotating shaft is fixedly sleeved with a spur gear 2, the spur gear 1 and the spur gear 2 are meshed with each other, the outside of the rotating shaft is fixedly sleeved with a spur gear 3, the outside of the hollow shaft is fixedly sleeved with a spur gear 4, the spur gear 3 and the spur gear 4 are meshed with each other, the outside of the hollow shaft is fixedly sleeved with a turntable, a plurality of telescopic arms are fixedly installed on the side wall of the turntable, and a cleaning pad is fixedly installed on one end of the plurality of telescopic arms.

[0009] Furthermore, a plurality of column feet are fixedly installed on the outside of the protective shell, a spring 2 is fixedly installed inside the plurality of column feet, a pad is fixedly installed on the top of the plurality of column feet, and a pulley is rotatably connected to the top of the column feet.

[0011] Furthermore, a plurality of detection devices are fixedly installed on the outside of the protective shell.

[0012] Furthermore, a plurality of groups of brushes are fixedly mounted on the upper side of the cleaning pad.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the utility model, the common power of multiple column feet is utilized to avoid the situation where water accumulates in the pipeline and it becomes difficult to move forward. The vibration structure is controlled by the driving motor to drive the conical vibration block to vibrate, so that the robot can open and clean the blocked pipeline, eliminating the financial and human resources wasted by manual cleaning of the channel and reducing the time wasted on inspection. In addition, the pads on the column feet can prevent the robot from losing balance due to pipeline damage and getting stuck in the pipeline.

[0015] 2. In the present invention, the telescopic arm is driven by the driving motor to rotate continuously to clean the inner wall of the pipeline, thereby preventing the inner wall of the pipeline from containing a large amount of oil and dirt, which would cause the robot's forward speed to slow down. Cleaning the pipeline can also prevent the oil and dirt from corroding the inside of the pipeline. Regular cleaning of the pipeline can greatly increase the service life of the pipeline. At the same time, the telescopic arm can continue to operate when the pipeline becomes narrower and will not get stuck inside the pipeline. This not only reduces the cost of maintaining the pipeline but also eliminates most of the manual operations. BRIEF DESCRIPTION OF THE DRAWINGS

A cleaning structure is installed in the protective shell 1, and the cleaning structure includes a spur gear 13 fixedly sleeved on the outside of the drive shaft 4, a rotating shaft 14 is rotatably connected to the side wall of the support plate 29, and a spur gear 2 15 is fixedly sleeved on the outside of the rotating shaft 14. The spur gear 13 and the spur gear 2 15 are meshed with each other, and a spur gear 3 17 is fixedly sleeved on the outside of the rotating shaft 14. The hollow shaft 16 is A spur gear four 18 is fixedly sleeved on the side, and spur gear three 17 and spur gear four 18 are meshed with each other.

[0023] The detailed working process of this utility model is as follows:

[0024] First, the operator puts the pipeline inspection robot into the pipeline, and remotely controls the robot, and uses the detection device 27 to perform inspection. This is the existing technology and will not be described in detail. Then the operator turns on the drive motor 3, and the drive motor 3 drives the rotating block 5 to rotate through the drive shaft 4. When the rotating block 5 rotates, it will contact the arc surface of the spherical slider 8, and then push the disc 7 forward when the rotating block 5 rotates. When the rotating block 5 does not contact the spherical slider 8, the disc 7 will move backward through the rebound of the spring 10, thereby achieving the forward and backward vibration effect. The disc 7 drives the striking disc 11 to vibrate through the slide rod 6, and the striking disc 11 drives the conical striking block 12 to vibrate, thereby completing the vibration and crushing of the objects blocked in front, avoiding the robot from encountering blockages during the forward movement. The robot is unable to move forward due to blocked items, and the need for staff to manually clean blocked items is avoided. At the same time, the driving shaft 4 also drives the rotating shaft 14 to rotate through the spur gear 1 13 and the spur gear 2 15. The rotating shaft 14 drives the hollow shaft 16 to rotate through the spur gear 3 17 and the spur gear 4 18. The hollow shaft 16 drives multiple telescopic arms 20 to rotate through the turntable 19. The rotation of the telescopic arms 20 drives the cleaning pad 21 and the brush 28 to clean the inner wall of the pipe, thereby preventing the inner wall of the pipe from containing oil and dirt, which causes the robot's forward speed to slow down and affect the detection effect. Cleaning the pipe can also prevent stains on the pipe from corroding the pipe, greatly extending the service life of the pipe. When arriving at the corresponding position, the operator uses the detection device 27 to detect the situation in the pipe, thereby completing the detection work.
