PROBLEM TO BE SOLVED: To make it possible to be aware of, at first glance from various places, a wind speed has reached a prescribe wind speed area, even in a facility, such as an electric power station, which has a large area and is crowded with buildings and equipment.SOLUTION: A flag 14 is allowed to be elevated any time through the drive of an elevation mechanism for the flag 14, by supporting the flag 14 on a support part, for example, on a high pole 13 or the like, which is visible from various places even in a facility, such as an electric power station, which has a large area and is crowded with buildings and equipment. A wind speed meter 15, which measures a wind speed and outputs a measurement value, is provided on the pole 13. In a case where the measurement value of the wind speed meter 15 reaches a prescribed wind speed area, the motor is driven and the flag 14 is ascended, thus making aware at first glance from various places that a wind speed has become equal to or higher than a certain degree. |
