The invention relates to the field of coating compositions, and particularly discloses an anti-icing self-cleaning coating material for a tower drum of a wind driven generator as well as a preparation method and application of the anti-icing self-cleaning coating material. The anti-icing self-cleaning coating material comprises a bottom coating material and a surface coating material, the bottom coating material contains fluorosilane, amino silane, ethyl acetate, butanone, filler, fluorocarbon resin and an isocyanate curing agent, the filler comprises alpha-Fe2O3 modified mesoporous SiO2 particles and hydroxylated boron nitride, and the surface coating material comprises fluorine modified SiO2 particles and acetone. The anti-icing self-cleaning coating material can achieve a good protection effect on the tower drum of the wind driven generator, the water contact angle of the surface of the coating is larger than 155 degrees, the water rolling angle is smaller than 5 degrees, the ice adhesion strength is smaller than 30 kPa, the water contact angle is still larger than 150 degrees after 20 times of freezing and thawing cycles, at the moment, the tower drum can better adapt to the low-temperature and high-humidity environment, the coating stripping possibility is low, and the anti-icing self-cleaning coating material can be applied to the wind driven generator tower drum. And the corrosion speed of the steel is reduced, so that the normal use time limit is longer.

The application discloses a swing arm type side mounting device, a side mounting wrecker and a side mounting method, relates to the technical field of wreckers, and comprises two oppositely arranged transverse traction telescopic mechanisms, and a tray is arranged below each of the two transverse traction telescopic mechanisms. Two scissor type lifting machines are arranged in the tray in front of and behind each other, and the two scissor type lifting machines can be laterally extended from the tray to the positions of the wheels of a fault vehicle and abut against the front edges and the rear edges of the wheels of the fault vehicle respectively, and are used for lifting the fault vehicle. The transverse traction telescopic mechanism can be extended to below the wheels of the lifted fault vehicle, and after the scissor type lifting machine is reset, the fault vehicle is transversely moved to a preset position. The application is combined with the independent tire supporting of the scissor type lifting machine and the non-alignment connection of the multi-stage sliding groove, utilizes the four-point tire supporting and the swing arm type side moving structure, eliminates the risk of the chassis of the rescued vehicle being bumped, greatly improves the stability and the automation degree of heavy load side mounting, and completely solves the problems of guiding jamming and unstable center of gravity in traditional side mounting operation.
