The drive rod 1 is made entirely of stainless steel and has an oleophobic layer on its surface to reduce the adhesion of oil. The telescopic rod 2 is a component for adjusting the length by electric drive in the prior art. Both are made of stainless steel to prevent oil from affecting the extension of the telescopic rod 2. The dispersing cone 5 is made of wear-resistant metal and is cone-shaped. It is mainly used to disperse oily substances that are adhering to and suspended on the pipe wall, and then disperse them under the drive of rotation.

[0029] Ensure that the drive rod 1 is connected to the external power supply, and check that the telescopic rod 2 and the tilting rod 3 are in their initial positions. Start the drive rod 1, and use electricity to extend the telescopic rod 2 to the appropriate length so that it can contact the inner wall of the pipe. Use the adjustment knob 9 on the tilting rod 3 to adjust the torque of the tilting rod 3 and the rotating component so that the dispersing cone 5 reaches the optimal working angle. Use the fixing bolt 8 in the threaded hole to ensure that the tilting rod 3 is stably fixed on the telescopic rod 2. Connect the rotating disk 4 to the tilting rod 3 through the connecting arm 13 to ensure that the rotating disk 4 can rotate freely. Start the hydraulic shaft 14 to increase the power output of the drive rod 1 and reduce the shaking when the rotating disk 4 rotates.
