The objective of the present invention is to provide an icing detection device installed on a nacelle, which is easy to install and manage, to indirectly measure the icing state of a blade with relatively high accuracy. To this end, the icing detection device according to the present invention comprises: a case; a vibration generator and a vibration receiver embedded in the case; and a vibration transmission tube arranged along the outer peripheral surface of the case and having one end connected to the vibration generator and the other end connected to the vibration receiver to transmit the vibration of the vibration generator to the vibration receiver, wherein the case has a convexly curved front surface, a plurality of protrusion units installed along the circumference of both side surfaces thereof at predetermined intervals, and an air flow valley formed between the protrusion units. Therefore, air colliding with the front surface of the case flows to both side surfaces of the case and passes from the front to the rear of the air flow valley, and the vibration transmission tube is installed on the circumference of the outer peripheral surface of the case to alternately pass through the air flow valley and the protrusion unit and in contact with the air passing through the air flow valley. |
