The invention relates to power equipment, particularly to a peculiar-smell type snake expelling device for an electric power line tower, The device is characterized in that the device is provided with a peculiar-smell box (4) in a shape like a container; the peculiar-smell box (4) is filled with a peculiar-smell agent (7) and is equipped with a mounting card connected with power equipment. The peculiar-smell type snake expelling device has the following beneficial effects: when approaching the device, a snake is simulated by the peculiar smell and moves away rapidly without arriving at the top of the tower, so that a short-circuit accident can be avoided. Moreover, the device has advantages of simple structure, convenient usage, and low cost. Especially for a switching unit, the device only releases the smell when any snake approaches, so that the replacement cycle of the peculiar-smell agent is extended substantially and the maintenance cost is reduced. Therefore, the provided device is expected to become a necessary device for an electric power line tower.
