The invention relates to the technical field of power auxiliary equipment, and aims to provide a simple winding device for a power cable. The problems that an existing power cable winding device is loose in winding and high in cost can be effectively solved. The simple winding device comprises a winding device body, the bottom end of the winding device body is arranged on a bottom plate, a protecting plate is arranged at one side edge of the winding device body, the other side edge of the winding device body is connected with a mounting plate, a plurality of guiding plates are arranged on thearc-shaped face of the inner side wall of the winding device body, a winding opening is reserved in one side edge of the bottom of the winding device body, a rotating shaft is arranged in the middle of the protecting plate, a connecting opening is reserved in the middle of the rotating shaft, and a winding drum sleeves the rotating shaft. The simple winding device has the beneficial effects that the simple winding device is connected with a hand-cranking rod or a motor through the connecting opening, using is convenient, the using cost can be effectively reduced, meanwhile, the guiding platesare arranged on the arc-shaped face in the winding device body, adjusting can be conducted in the power cable winding process, the phenomenon of loose winding due to the excessively large span of thepower cable is reduced, and practicality and reliability are achieved.
