AI Technical Summary
In existing trenchless repair devices for pipes, it is difficult to achieve uniform pressure distribution when fixing the lining material, resulting in uneven adhesion between the lining material and the original pipe, and making it impossible to achieve overall repair of the inner wall of the pipe.
The linear movement of the nut and slider is driven by a lead screw, combined with the switching motion of the swing arm and crankshaft connecting rod to achieve the rotational cleaning of the cleaning roller; microwave energy is transmitted to the heating rod and heating ring through a micro microwave generator and waveguide converter to achieve uniform heating and repair of the inner wall of the pipe.
This method achieves uniform cleaning and heat repair of the pipe's inner wall, ensuring that the lining material fits tightly with the original pipe, thus improving the uniformity and efficiency of the repair.
