[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the embodiment of this utility model, a pipe crawler for pipe inspection includes a circular plate 1. The circular plate 1 is characterized by a walking mechanism, which includes an adjustment component. The adjustment component includes a set of sliding grooves 2 on the circular plate 1, a sliding block 3 slidably connected within the sliding grooves 2, a first fixed plate 4 on the sliding block 3, a second fixed plate 5 fixedly connected to the first fixed plate 4, and a drive wheel 6 mounted on the second fixed plate. The circular plate 1 is also equipped with an adjustment component for adjusting the set of second fixed plates 5. A cleaning component is also provided on the circular plate 1 for cleaning the pipe. During operation, the positions of the first fixed plate 4, the second fixed plate 5, and the drive wheel 6 are adjusted using the adjustment component, allowing the drive wheel 6 to conform to the inner wall of the pipe. This solves the problem in the prior art where the crawler cannot make slight adjustments according to the size of the pipe it enters, requiring different equipment for inspecting pipes of different sizes, which is inconvenient for users.

[0024] The adjustment assembly includes a set of rectangular plates 7 fixed to one side of a circular plate 1. An electric actuator 8 is fixed between the set of rectangular plates 7 via a set of connecting rods. The telescopic end of the electric actuator 8 passes through the side wall of the circular plate 1. A square column 9 is fixed to the telescopic end of the electric actuator 8. A set of first fixing blocks 10 is fixed to the square column 9. A rotating rod 11 is rotatably connected to the first fixing block 10 via a first rotating shaft. A second fixing block 12 is fixed to the second fixing plate 5. One end of the rotating rod 11 is rotatably connected to the second fixing block 12 via a second rotating shaft. During operation, the retraction of the electric actuator 8 can drive the square column 9 to move. This allows a set of sliding blocks 3, the first fixing plate 4, and the second fixing plate 5 to move under the connection of the first fixing block 10, the second fixing block 12, and the rotating rod 11. This allows the drive wheel 6 to fit against the inner wall of the pipe under the drive of the second fixing plate 5, thus adapting to pipes of different sizes.

[0025] The cleaning assembly includes a bottom shell 13 fixed to a set of rectangular plates 7. A closed shell 14 is threaded onto the bottom shell 13. A vacuum pump 15 is installed on the side wall of the closed shell 14. A suction nozzle 16 is connected to the suction end of the vacuum pump 15. During operation, the installed vacuum pump 15 can effectively remove dust, moisture and other impurities from the pipeline, reducing the interference of these substances on the detection equipment (such as cameras or sensors), thereby improving the accuracy and reliability of the detection results.

[0026] A pair of upright plates 17 are fixed to the side wall of the enclosed shell 14. An elastic telescopic rod 18 is fixed to the upright plate 17. A traveling wheel 19 is fixed to the telescopic end of the elastic telescopic rod 18. A support plate 20 is fixed to the pair of upright plates 17. During operation, the traveling wheel 19 installed on the set elastic rod can automatically adjust the size according to the inside of the pipe, thereby adapting to pipes of different diameters and expanding the application range of the robot.

[0027] A motor 21 is fixed to the side wall of the support plate 20 via a pair of L-shaped rods. The output end of the motor 21 is provided with a drive rod 22, and one end of the drive rod 22 is rotatably connected to the side wall of the support plate 20 and passes through the other side of the support. A concave rod 23 is fixed to the drive rod 22, and a set of brushes 24 are fixed to both ends of the concave rod 23. During operation, the motor 21 drives the drive rod 22 and the concave rod 23 to rotate, thereby driving the brushes 24 to clean the inner wall of the pipe. The rotating brushes 24 can rotate at high speed, effectively removing dirt, deposits and attachments from the inner wall of the pipe, and improving cleaning efficiency.

[0028] Working principle: The positions of the first fixed plate 4, the second fixed plate 5, and the drive wheel 6 are adjusted by the set adjustment components, allowing the drive wheel 6 to fit against the inner wall of the pipe. This solves the problem that existing crawlers cannot make slight adjustments according to the size of the pipe they enter, which requires different equipment when inspecting pipes of different sizes, causing inconvenience to users. The electric push rod 8 retracts, which drives the square column 9 to move. This, in turn, moves a set of sliding blocks 3, the first fixed plate 4, and the second fixed plate 5 through the connection of the first fixed block 10, the second fixed block 12, and the rotating rod 11. This allows the drive wheel 6 to move along the second fixed plate 5. Driven by the vacuum pump 15, the robot conforms to the inner wall of the pipe, thus adapting to pipes of different sizes. The installed vacuum pump 15 effectively removes dust, moisture, and other impurities from the pipe, reducing interference from these substances on the detection equipment (such as cameras or sensors), thereby improving the accuracy and reliability of the detection results. The elastic rod is equipped with a walking wheel 19, which can automatically adjust according to the size of the pipe, thus adapting to pipes of different diameters and expanding the robot's application range. The motor 21 drives the drive rod 22 and the concave rod 23 to rotate, thereby driving the brush 24 to clean the inner wall of the pipe. The rotating brush 24 can rotate at high speed, effectively removing dirt, deposits, and attachments from the inner wall of the pipe, improving cleaning efficiency.
