As shown in fig. 11, when the cleaning head 13 needs to spray stronger water flow to the gap formed by the stabilizing rod 26 and the movable rod 23 for cleaning, water flow is simultaneously conveyed to the water inlet channel 41 through the water tank 15 and wind power is conveyed to the air channel 42 through the fan 16, so that the wind power and the water flow form pressure balance to the corresponding sealing plugs 44, the sealing plugs 44 are forced to slide along the supporting columns 45 under the pressure of the wind power and the water flow, the communication between the water inlet channel 41 and the air channel 42 and the cleaning channel 43 is opened, the wind power drives the water flow to spray and clean to the movable protection assembly 20, the corrosion of the movable protection assembly 20 is avoided, the service life of the movable protection assembly 20 is prolonged, and more favorable protection for cables is formed.

Example three:

a charging pile 200, wherein, has the technical characteristics related to the wear-proof sheath structure 100 in any one of the first or second embodiments.

Example four:

a method of wear protection, comprising the steps of:

before charging, the cable is fixed by a fixed chuck 21 of a movable protective component 20 in the casing box 10;

when charging is needed, the cable in the sleeving box 10 is pulled out, the fixed chuck 21 is driven to move outwards at the same time, the fixed chuck 21 moves to drive the upper connecting rod 22 to move, the movable rod 23 movably connected with the connecting rod 22 is pulled, two movable rods are overlapped together, the movable rods 23 forming a layer-by-layer structure are stretched and attached to the cable one by one from top to bottom, meanwhile, the protective films 27 arranged on the inner sides of the movable rods 23 and the stabilizing rods 26 are sleeved on the cable in a wrapping mode, and finally, the cable is protected;

then when the cable is pulled out and falls on the ground to be dragged, firstly, the outer movable rod 23 of the cable is in direct contact with the ground to separate the cable from the ground, so that abrasion caused in the cable dragging process is avoided, if liquid and/or sundry attachments exist on the ground, and in the cable dragging process, the protective film 27 between the cable and the movable rod 23 can prevent the liquid and/or sundry from being directly attached to the cable, so that the accelerated corrosion damage of a cable protective skin layer is avoided;

after the charging is completed, in the process that the cable is pulled back to the box-type housing 10, the movable rod 23 and the protective film 27 protect the cable, and the fixed chuck 21 pushes the connecting rod 22 to apply pressure to the movable rod 23, so that the movable rod 23 is folded and stored in the box-type housing 10 again, if there is an attachment on the movable rod 23 and/or the protective film 27, a gap formed by the stabilizing rod 26 connected with the movable rod 23 is beneficial to enabling water flow and/or wind power to clean the movable rod 23 and the protective film 27, and the service life of the movable protective assembly 20 is prolonged.
