A cable winding device for power construction, relating to the field of power construction equipment, includes a mobile platform, a cable winding device, and a jet-blowing dust collection device. The jet-blowing dust collection device is equipped with a rotatable jet-blowing component, with a cable channel at its center and radially distributed nozzles pointing towards the cable; a drive mechanism drives the jet-blowing component to rotate around the cable; fixed dust collection devices are symmetrically arranged on both sides of the jet-blowing component along its axial direction; an air supply
system supplies air to the jet-blowing component and provides negative pressure to the dust collection devices through a negative pressure fan. By employing the synergistic effect of rotary jet-blowing and negative pressure dust collection, non-contact dynamic cleaning is achieved, completely solving the problems of cable scratches, secondary dust adsorption, and
dust pollution caused by traditional
brush cleaning.
