Further, a blade of a large wind power generator is subject to lightning damage.
However, when a lightning receiving portion has conduction failure, a blade is broken due to a stroke of lightning.
Therefore, a blade of a large wind power generator requires regular maintenance.
Since the first method and the second method use a large crane, said methods require much cost and labor.
Especially, the first method requires enormous cost and a long construction period due to a step of removing a blade and a step of attaching the blade.
The second method and the third method are dangerous because said methods require a worker to work at a high place.

Embodiment Construction
[0070]The embodiments of the present invention are explained hereinafter with reference to the drawings.
[0071]1. Maintenance on a Blade of a Wind Turbine
[0072]FIG. 1 to FIG. 3 are used to explain a state in which a device 100 for performing maintenance on a blade of a wind turbine performs maintenance on a blade 11 of a wind turbine 10. FIG. 1A, FIG. 2A, and FIG. 3A show the front of the wind turbine 10, and FIG. 1B, FIG. 2B, and FIG. 3B show the right side of the wind turbine 10. FIG. 1B, FIG. 2B, and FIG. 3B only show the blade 11 subjected to maintenance, in which the other two blades 12 and 13 are omitted. The wind turbine shown in FIG. 1A, FIG. 2A, and FIG. 3A is a wind turbine that rotates clockwise on the drawings, in which a linear edge of each blade is a leading edge (front edge).
[0073]As used herein, “wind turbine” refers to a device that obtains motive power by the wind. One example of a wind turbine is a wind power generator.

A device for performing maintenance on an object is provided. The device for performing maintenance on an object comprises an attaching means that enables the device to attach to a part of an object, the attaching means being configured to deform in accordance with a shape of a part of the object, a moving means that enables the device to move on the object, and a maintenance means that performs maintenance on the object. In one embodiment of the present invention, the attaching means is configured so that the device maintains a state of attaching to the part of the object by the deformation of the attaching means even when a shape of a part of the object changes in association with the movement.
Description
TECHNICAL FIELD[0001]The present invention relates to a device, system, and method for performing maintenance on an object.BACKGROUND ART[0002]A large wind power generator has a height of about 100 m. The peripheral speed of a wing tip of a blade of a large wind power generator is about 100 to 120 m / s, and a leading edge (front edge) of a blade, which is an edge cutting through the air, is worn away at a rate of about 20 μm per year. Further, a blade of a large wind power generator is subject to lightning damage. Thus, a blade is equipped with a lightning receiving portion for making lightning stroke current flow to the ground as lightning resistant measures. However, when a lightning receiving portion has conduction failure, a blade is broken due to a stroke of lightning. Therefore, a blade of a large wind power generator requires regular maintenance.[0003]There are three representative methods for performing maintenance on a blade of an existing large wind power generator. The fir...
