The invention belongs to the technical field of high voltage power operation, and especially relates to a deicing mechanism on a single high voltage power line. The deicing mechanism comprises the high voltage power line, a deicing element, a front board, an upward floating Geneva wheel, an initiative flexible Geneva wheel, an electric motor, a rotation Geneva wheel, a downward floating Geneva wheel and a base. The deicing element is mounted on the front board. The high voltage power line penetrates the deicing element. The electric motor drives the deicing element to carry out rotation movement, and therefore, the unfrozen water or ice on the high voltage power line can be thrown away from the high voltage power line, thereby realizing a deicing purpose. Through design of the four Geneva wheels, it can be ensured that the device can operate stably on the high voltage power line. The energy source used by the deicing mechanism is solar energy. The solar energy is stored in charging batteries in sunny days. When bad weather appears, the energy can be supplemented by the charging batteries for a relatively long time, thereby carrying out deicing service. The designed structure provided by the invention is relatively high in integration degree and has certain modular design concepts and certain practical effects.
