Turntables 4 are rotatably mounted on both ends of the fixed base 1 through meshing drive mechanisms with opposite rotation directions. A detection mechanism is mounted on one end of the fixed rod 5, and a power supply line 6 connected to the detection mechanism is embedded in the other end of the fixed rod 5. A rotating seat 7 is fixed on the side wall of the turntable 4. Multiple wheel mounting brackets 8 are fixed in a ring array on the outer wall of the rotating seat 7. Mecanum wheels 15 are fixed on the wheel mounting brackets 8.

[0027] The detection mechanism includes a detection rod 3 connected to a fixed rod 5 and a camera 2 embedded and fixed on the detection rod 3. The turntable 4 and the rotating seat 7 are both fitted on the fixed rod 5. The outer wall of the fixed seat 1 has grooves 12 arranged in a ring array. A motor 10 is embedded and fixed in the grooves 12. The meshing drive mechanism includes a first gear 9 fixed on the shaft of the motor 10 and a second gear 11 embedded and fixed in the turntable 4. The first gear 9 and the second gear 11 are meshed and connected. After the motor 10 is started, it drives the turntable 4 and the rotating seat 7 to rotate through the first gear 9 and the second gear 11. The Mecanum wheel 15 on the outer wall of the rotating seat 7 abuts against the inner wall of the pipe. The spring plate 16 on the mounting bracket can make the Mecanum wheel 15 fit firmly against the inner wall of the pipe, increasing the friction between the wheel and the inner wall and making it less prone to slippage.

[0028] like Figure 3 and Figure 4 As shown, a first bolt 13 is installed on the side wall of the wheel mounting bracket 8. The first bolt 13 is threaded into the rotating seat 7. A spring plate 16 is fixed on the wheel mounting bracket 8. A Mecanum wheel 15 is fixed to the side wall of the spring plate 16. A connecting seat 17 is provided on the spring plate 16 and is rotatably inserted into the Mecanum wheel 15. A second bolt 14 is provided on the side wall of the Mecanum wheel 15 and is threaded into the connecting seat 17. The rotation direction of the Mecanum wheel is controlled, thereby controlling the robot's forward and backward movement. The inner wall of the pipe is detected by the camera 2 on the detection rod 3, which facilitates movement within the inner wall of narrow pipes.

[0029] Working principle: When using the device of this technical solution, the detection rods 3 and rotating seat 7 at both ends of the fixed base 1 are inserted into the pipe. The spring plate 16 on the mounting bracket makes the Mecanum wheel 15 firmly adhere to the inner wall of the pipe, increasing the friction between the wheel and the inner wall and making it less prone to slippage. After the motor 10 is started, it drives the turntable 4 and rotating seat 7 to rotate through the first gear 9 and the second gear 11. The Mecanum wheel 15 on the outer wall of the rotating seat 7 abuts against the inner wall of the pipe, controlling the rotation direction of the Mecanum wheel and thus controlling the robot's forward and backward movement. The inner wall of the pipe is detected by the camera 2 on the detection rod 3, which facilitates movement on the inner wall of narrow pipes and improves the stability and convenience of detecting the inner wall of narrow pipes.
