Description

APPARATUS FOR MONITORING FASTENING CONDITION OF ELEMENT CONNECTING TOWER SEGMENT OF WIND POWER GENERATOR}

The present invention relates to a device for monitoring the fastening state of the wind turbine tower segment coupling member.

The tower of a wind turbine (hereinafter referred to as a “wind generator”) is a structure that supports a nacelle that converts the rotational force of a blade into electrical energy. Inside the tower, as well as a ladder that allows the operator to safely climb up to the nacelle, the electric transport device is recently installed for the convenience of the worker's mobility. In addition, a cable tray supporting a power line is installed in the tower to transfer electricity generated from a generator inside a nacelle to an electric system on the ground.

Such towers are typically formed by assembling or combining several tower segments that can be disassembled. At this time, the coupling portion of each tower segment is provided with a circumferential flange having a plurality of fastening holes. The flange of each tower segment is formed by a tower that is joined by bolts and nuts to support the nacelle.

In addition, the tower may be affected by various internal or external environments, such as wind and vibration. At this time, if the fastening state of the bolt and nut joining each tower segment is relaxed by the influence of the external force can be a great threat to safety.

Therefore, in the related art, a worker regularly climbs up a ladder installed in a tower to check a fastening state of a bolt and a nut by using a test equipment, or, if necessary, tightens some bolts and nuts which are loosened by using a fastening means. In this case, it takes a lot of time to check the tightness of the bolts and nuts that join the entire tower segment, and may simply pass some loose bolts and nuts due to operator error.

In addition, in Korean Patent Publication No. 2010-0085707, when the nut is loosened, the conductive wire wound on the nut is disconnected so that the manager can recognize the fastening state of the bolt and the nut quickly. However, the manager can recognize the fact only when the nut is already loosened above a certain threshold and the disconnection of the conductive wire occurs. Therefore, the bolt and nut have been loosened more than the predetermined threshold by monitoring the fastening state of the bolt and nut. There is a problem that cannot be prevented.
