The driving assembly 55 is arranged in the shell 2 and is in transmission connection with the sun gear 53. The power transmission line 7 is passed through the through hole 21 on the shell 2 and the communication hole on the sun gear 53. After the plastic bag and other foreign matters appear on the power transmission line 7 in front of the shell 2, the driving assembly 55 is started to drive the sun gear 53 to rotate, thereby driving the planet gear 54 to rotate between the sun gear 53 and the gear ring 52, and the first extension rod 51 also rotates and contacts the plastic bag hanging on the power transmission line 7. Under the action of the adhesive on the first extension rod 51, the plastic bag cannot fall off the first extension rod 51, so that the plastic bag is wound on the first winding rod layer by layer and is torn off from the power transmission line 7 by the first extension rod 51. Through the rotation of the planet gear 54 between the gear ring 52 and the sun gear 53, the first extension rod 51 is driven to rotate around the power transmission line 7, the plastic bag is bonded to the adhesive on the first extension rod 51, and then the plastic bag is torn off from the power transmission line 7. The effect of cleaning the plastic bag is good, the residual plastic bag is less, and the first extension rod 51 will not damage the power transmission line 7. The driving assembly 55 is a third motor in key connection with the sun gear 53.

[0050] Please refer to Figure 3 and Figure 10 As a specific embodiment of the power transmission line inspection and maintenance platform provided by the present application, the sun gear 53 is provided with a second extension rod 56 on the side away from the shell 2, and the second extension rod 56 is coated with adhesive. The sun gear 53 is provided with a second extension rod 56 on the side away from the shell 2, and the second extension rod 56 is coated with adhesive. The first extension rod 51 has a larger radius of rotation, is suitable for hanging a longer plastic bag, and has a faster cleaning speed. However, it is difficult to effectively remove a smaller plastic bag. Therefore, the second extension rod 56 is installed on the end face of the sun gear 53 away from the shell 2. The second extension rod 56 has a smaller radius of rotation and can directly stick the shorter plastic bag through the adhesive during the rotation of the sun gear 53, and then tear off the plastic bag. In this way, the first extension rod 51 and the second extension rod 56 are respectively installed on the planet gear 54 and the sun gear 53, which can remove both longer and shorter plastic bags, thereby improving the removal range of the power transmission line inspection and maintenance platform. The first extension rod 51 has a larger radius of rotation and can quickly remove a longer plastic bag. The second extension rod 56 has a smaller radius of rotation and can smoothly remove a shorter plastic bag from the power transmission line 7.

[0051] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
