[0033] Among them, the visual inspection head 13 of the present application can use laser visual inspection equipment, ultrasonic visual inspection equipment, or infrared visual inspection equipment.

[0034] like Figure 2 As shown, the wheel 23 can be connected to the outer wall of the cable 1 through friction transmission, so that when the handle 12 is held to move the U-shaped arm 11, the wheel 23 is driven to rotate, making the device more stable during movement and avoiding adverse effects on the detection operation of the visual inspection head 13.

[0035] In addition, a concave arc surface may be provided on the side of the wheel 23 to increase the abutment effect with the outer side wall of the cable 1 .

[0037] When using the power line surface defect detection mechanism of the present application to perform defect detection on the outer surface of the cable 1, the U-shaped arm 11 is covered on the outside of the cable 1, so that multiple visual inspection heads 13 are simultaneously located around the cable 1, and the outer side of the cable 1 is observed in all directions, thereby reducing the observation blind area and increasing the detection effect of the power line surface defects.
