lubricating oil can lubricate the surfaces of the wire grooves and the traction rope 17, so that resistance in relative motion of the traction rope 17 and the wire grooves is reduced, when the traction rope 17 slides back and forth to enable part of the lubricating oil to flow into the air holes 8 along the wire grooves, the lubricating oil can intensively flow into the recovery groove 18, then the recovery strip 19 absorbs the lubricating oil in the recovery groove 18, and the lubricating oil can be coated on the attached traction rope 17, so that the lubricating oil can be recycled; in rainy days, the gravity of the water absorption block 21 is gradually increased after the water absorption block absorbs rainwater, and the baffle 22 is driven to gradually move downwards until the baffle 22 blocks the air hole 8, so that the condition that the service life of the super capacitor 2 is influenced because air with moisture flows into the protective sleeve 3 when the fan blade 6 rotates in rainy days is reduced; in rainy days, the water absorption layer 23 can be in contact with rainwater in a larger area and is transferred into the water absorption block 21 through the conveying strips 24, so that the water absorption block 21 can be saturated more quickly and drive the baffle 22 to block the air holes 8, meanwhile, in sunny days, the water absorption layer 23 containing rainwater can play a certain cooling effect on the surface of the protective sleeve 3, and the heat dissipation effect in the protective sleeve 3 is further improved; when raining, the rotary sleeve 13 can drive the sliding block 14 to intermittently slide through the pressure plate 25 when rotating, and apply intermittent repulsive force to the pressure plate 25, so that the pressure plate 25 rotates under force and pushes the water absorbing layer 23 back and forth, thereby promoting the water in the water absorbing layer 23 to be discharged, indirectly promoting the water in the water absorbing block 21 to be discharged, enabling the water absorbing block 21 to be reset more quickly under the action of the elastic block 20, and enabling the air holes 8 to be opened timely, thereby enabling the heat dissipation fan 7 to play a role of air exchange and heat dissipation in the protective sleeve 3 when working; haulage rope 17 can extrude the extrusion portion 27 to having lubricating oil through bulge 26 when making a round trip to slide in the wire casing, make its inside lubricating oil can effectual outflow, thereby make recovery strip 19 can be continuous retrieve to reuse in the wire casing with the lubricating oil of collecting in recovery tank 18, the delivery member 28 of extrusion portion 27 department can absorb extruded lubricating oil simultaneously, and to whole delivery member 28 infiltration transmission, reduce the condition that lubricating oil concentrates the gathering in bulge 26 department of haulage rope 17, and lubricating oil can be through the more even distribution of water absorption strip 29 on each delivery member 28, thereby the whole lubricated effect of delivery member 28 to haulage rope 17 has been improved.
