め能率的な作業ができなくなるという問題がある。In general, wind turbines used for wind power generators and the like usually have their rotors mounted at the top of tall towers so that the energy of natural wind can be detected as efficiently as possible. However, when the rotor is mounted at such a high position, there is a problem that maintenance work such as periodic inspection and repair of the rotor is forced to be carried out at a high place, making it impossible to perform the work efficiently.
本発明の目的は、ロータがタワーの高所に取り付けられ
ていても、メンテナンス作業を能率的に簡単に行えるよ
うにする風車用タワーを提供することにある。An object of the present invention is to provide a wind turbine tower that allows maintenance work to be performed efficiently and easily even when the rotor is mounted at a high location on the tower.
上記目的を達成する本発明は、タワーの上部にロータを
取りつけた風車において、前記タワーの下部を折曲自在

力するようにしている。The figure shows a wind turbine generator having a wind turbine tower according to an embodiment of the present invention. Reference numeral 1 denotes a vertically extending tower installed on a base 1a, and a rotor 3 is connected to the upper end of the tower via a nacelle 2.
is installed. This rotor 3 is constructed by having two blades 5.5 arranged oppositely on a hub 4. The nacelle 2 is rotatably supported at the upper end of the tower 1 and supports a rotation shaft (not shown) therein, and the rotor 3 is attached to the tip thereof. 6 is a yoke case with a built-in generator, and the rotation of the rotor 3 is manually applied to the generator.

してウィンチ１２に連結されている。The lower part of the tower 1 is bendably connected to the base 1a via a hinge 7, so that the tower 1 can be alternately switched between an upright position shown by a solid line and a collapsed position shown by a chain line. Bearings 8.8 are fixed to the base 1a on both sides of the tower 1, and the lower end of a triangular gin pole 9 is pivotally supported on the bearings 8,8. Further, a long connector 10 such as a tensile wire or a tensile rod is connected between the upper end of the gin pole 9 and the upper part of the tower 1, and the upper end of the gin pole 9 is connected to a winch 12 via a traction wire 11. is connected to.

しである。Therefore, by winding back the tow wire 11 using the winch 12, the tower 1 can be switched from the upright position to the lodging position via the gin pole 9 and the long connector 10, and by winding it up, the tower 1 can be switched from the upright position to the lodging position. It can be switched from the standing position to the standing position. The gin pole 9 and the long connector 10 are detachable so that they can be attached when performing maintenance work or the like and removed when operating the windmill. Furthermore, when the windmill is operated with the gin pole 9 and the long connector 10 removed, the bent portion of the hower 1 is fixed with bolts or the like so that it cannot be placed in a laid down position.
上述した風車によると、タワーが折曲げ自在で、かつ起

うになり、高所で行うことはないから、極めて能率的に
作業することができる。According to the above-mentioned wind turbine, the tower is configured to be bendable and can be switched alternately between the upright position and the down position, so when performing maintenance work such as inspection or repair of the rotor or generator, etc. Is the tower in the collapsed position as shown by the chain line in Figure 1? This allows work to be done on the ground and not at heights, making it extremely efficient.
