Description

本発明は、風力発電装置のブレードの外周面の塗装、修理等のメンテナンス作業を行うことができる風力ブレード点検装置に関する。 The present invention relates to a wind blade inspection device that can perform maintenance work such as painting and repairing the outer surface of the blades of a wind power generation device.

一般に、風力発電装置は、風を受けるブレードとハブを組み合わせたローターと、このローターの回転を受ける装置が入ったナセルと、このナセルを支持する垂直に高いタワー等で構成されている。
風力発電装置のメンテナンスは、機器の状態を正常に保つために不可欠な作業であり、このメンテナンス作業には日常的に行う点検や実施時期を決めて行う定期点検、損傷や故障・劣化などが確認された際に行う修理・補修などがある。
風力発電装置のエネルギー源である風を直接受けるブレードは、その特質上、日射や風雨に曝されるため、他の部品に比べて劣化しやすく、その補修等が特に重要になる。 Generally, a wind turbine generator is composed of a rotor that combines blades and a hub that catch the wind, a nacelle that contains a device that rotates the rotor, and a tall vertical tower that supports the nacelle.
Maintenance of wind power generation equipment is essential for keeping the equipment in good condition. This maintenance work includes daily inspections, periodic inspections at set times, and repairs and maintenance when damage, malfunctions, or deterioration is found.
The blades of a wind turbine generator are directly exposed to wind, which is the energy source of the generator. Because of this, they are exposed to sunlight, wind and rain, and are therefore more susceptible to deterioration than other components, making repairs to them particularly important.

そこで、風力発電装置の円柱形状のタワーの上部に配置したナセルから、メンテナンス用のゴンドラを吊下げてブレードを保守点検することが考えられている。
円柱形状の鉄塔（タワー）の上部に配置しているナセルの近傍にフレーム本体を固定し、このフレーム本体にワイヤーを介して円形ゴンドラを吊設することにより、極めて画一的な作業を実現して、作業時間の短縮、作業労力の削減を図った水平軸型発電システムに用いられる円柱形状の鉄塔のメンテナンス用ゴンドラ吊り機構が知られている（特許文献１を参照）。 As a result, it has been considered to suspend a maintenance gondola from a nacelle located at the top of the cylindrical tower of the wind turbine generator to perform maintenance and inspection of the blades.
A gondola suspending mechanism for maintenance of a cylindrical steel tower used in a horizontal axis power generation system is known, which involves fixing a frame body near a nacelle located at the top of a cylindrical steel tower and suspending a circular gondola from this frame body via a wire, thereby enabling extremely uniform work to be performed, thereby shortening work time and reducing work labor (see Patent Document 1).

この公知技術は、ナセル本体の壁面に孔を設けてワイヤー等の吊り機構を配置することにより、ナセルに吊設されたフレーム本体と、このフレーム本体に吊設されたゴンドラと、から成ることから、鉄塔にゴンドラを配置する際に極めて画一的な作業を実現して、作業時間の短縮、作業労力の削減を図ることができる。 This known technology involves creating holes in the wall of the nacelle body and arranging a hanging mechanism such as a wire in the hole, which consists of a frame body suspended from the nacelle and a gondola suspended from the frame body. This allows for extremely uniform work when placing the gondola on the tower, shortening work time and reducing work effort.

また、昇降機と牽引ロープのみでゴンドラを昇降させるブレードメンテナンス用のゴンドラ装置が開発されている（特許文献２を参照）。
この公知技術は、ナセルから吊り下げた三本の牽引ロープで吊下げられたゴンドラ装置が、この牽引ロープを巻き付けたゴンドラ装置の昇降機を介して、地上の位置から上方の位置まで昇降させ、ブレードの外周面の塗装、修理等のメンテナンス作業を行うものである。 Also, a gondola device for blade maintenance has been developed in which a gondola is raised and lowered using only an elevator and a towing rope (see Patent Document 2).
In this known technology, a gondola device suspended by three towing ropes hanging from a nacelle is raised and lowered from a ground position to an upper position via an elevator around the gondola device, around which the towing ropes are wrapped, to perform maintenance work such as painting and repairs on the outer surface of the blades.

次に、本発明の風力ブレード点検装置の実施例１の操作動作を添付図面に基づいて、以下に説明する。
通常時の風力発電装置の運転時には、牽引ロープ８を地上まで引き延ばして主ロープ１８から支えロープ１９を外して、メンテナンス用ゴンドラ９は地上に設置又は保管しておく。
一方、図２に示す巻上げドラム７により主ロープ１８を一対の滑車６まで巻上げ、ピニオン１６を回転して伸縮ガイド棒５を後退させて一対の滑車６がブレード３の回転の妨げにならない位置まで後退させて置く。 Next, the operation of the wind blade inspection device according to the first embodiment of the present invention will be described below with reference to the accompanying drawings.
During normal operation of the wind power generating device, the towing rope 8 is stretched to the ground, the support rope 19 is detached from the main rope 18, and the maintenance gondola 9 is installed or stored on the ground.
Meanwhile, the main rope 18 is wound up to the pair of pulleys 6 by the winding drum 7 shown in Figure 2, and the pinion 16 is rotated to retract the telescopic guide rod 5 to a position where the pair of pulleys 6 do not interfere with the rotation of the blade 3.

メンテナンス作業時には、ピニオン１６を回転して伸縮ガイド棒５を前進させて一対の滑車６がブレード３の点検可能位置まで前進させ、巻上げドラム７を回転させて一対の滑車６を介して主ロープ１８を巻き戻して吊下げ、地上付近まで主ロープ１８を吊下げる。
地上に設置又は保管しておいたゴンドラ駕籠２０の四隅に設けた支えロープ１９を主ロープ１８の先端に連結し、巻上げドラム７を回転させてブレード３の点検位置まで上昇させる。
ブレード点検位置では、前記ゴンドラ駕籠２０に設けた伸縮シリンダー２３により前記揺れ止め伸縮棹２１を伸ばしてブレード３の円弧面に接合させ、吸引カップ２２を円弧面に吸着させてゴンドラ駕籠２０の揺れを防止する。 During maintenance work, the pinion 16 is rotated to advance the telescopic guide rod 5 so that the pair of pulleys 6 advance to a position where the blade 3 can be inspected, and the hoist drum 7 is rotated to rewind and suspend the main rope 18 via the pair of pulleys 6, so that the main rope 18 is suspended near the ground.
Support ropes 19 provided at the four corners of a gondola palanquin 20 installed or stored on the ground are connected to the ends of the main ropes 18, and the hoist drum 7 is rotated to raise the gondola palanquin 20 to an inspection position for the blade 3.
At the blade inspection position, the anti-sway telescopic rod 21 is extended by the telescopic cylinder 23 provided on the gondola palanquin 20 and joined to the arcuate surface of the blade 3, and the suction cup 22 is attached to the arcuate surface to prevent the gondola palanquin 20 from swaying.

ブレード点検が終わる度に、吸引カップ２２の吸引を止め、揺れ止め伸縮棹２１を縮め、巻上げドラム７を回転させて上方のブレード３の点検位置まで上昇させる。
この動作を繰り返してブレード３の点検を行うが、ブレード３は３枚あるので、１枚が終わると、ゴンドラ駕籠２０を地上まで降ろして、牽引ロープ８の主ロープ１８から支えロープ１９を外して、巻上げドラム７により主ロープ１８を一対の滑車６まで巻上げ、ピニオン１６を回転して伸縮ガイド棒５を後退させて一対の滑車６がブレード３の回転の妨げにならない位置まで後退させる。 After each blade inspection, the suction of the suction cup 22 is stopped, the anti-sway telescopic rod 21 is retracted, and the winding drum 7 is rotated to raise the blade 3 to an inspection position above.
This operation is repeated to inspect the blades 3, but since there are three blades 3, once one is finished, the gondola palanquin 20 is lowered to the ground, the support rope 19 is detached from the main rope 18 of the towing rope 8, the main rope 18 is wound up to the pair of pulleys 6 by the hoist drum 7, and the pinion 16 is rotated to retract the telescopic guide rod 5 so that the pair of pulleys 6 are retracted to a position where they do not interfere with the rotation of the blades 3.

その後、ブレード３を回転させて新たなブレード３を垂直姿勢の状態にし、以下同様にして、新たなメンテナンス作業に入る。
このように、本発明の風力ブレード点検装置は、ナセル２の背上面に固定された巻上げ機構４と、該巻上げ機構４の伸縮ガイド棒５の先端に設けた一対の滑車６と、前記巻上げ機１１の巻上げドラム７から前記滑車６間を介して吊下げられた牽引ロープ８と、該牽引ロープ８の先端に固定されたメンテナンス用ゴンドラ９と、から構成されるため、風力発電装置のブレード３の外周面の塗装、修理等のメンテナンス作業を簡易な構造で短時間に行うことができる。 Thereafter, the blade 3 is rotated to bring a new blade 3 into a vertical position, and a new maintenance operation is started in the same manner.
In this way, the wind blade inspection device of the present invention is composed of a winding mechanism 4 fixed to the upper back surface of the nacelle 2, a pair of pulleys 6 attached to the end of the telescopic guide rod 5 of the winding mechanism 4, a towing rope 8 suspended from the hoisting drum 7 of the hoist 11 between the pulleys 6, and a maintenance gondola 9 fixed to the end of the towing rope 8, so that maintenance work such as painting and repairs on the outer surface of the blades 3 of a wind turbine generator can be performed in a short time with a simple structure.

この動作を繰り返してブレード３の点検を行うが、ブレード３は３枚あるので、１枚が終わると、ゴンドラ駕籠２０を地上まで降ろして、牽引ロープ８の主ロープ１８から支えロープ１９を外して、巻上げ機７により主ロープ１８を一対の滑車６まで巻上げ、ピニオン１６を回転して伸縮ガイド棒５を後退させて一対の滑車６がブレード３の回転の妨げにならない位置まで後退させる。 After each blade inspection, the suction of the suction cup 22 is stopped, the anti-sway telescopic rod 21 is retracted, and the winch 7 is rotated to raise the blade 3 up to an inspection position.
This operation is repeated to inspect the blades 3, but since there are three blades 3, when one is finished, the gondola palanquin 20 is lowered to the ground, the support rope 19 is detached from the main rope 18 of the towing rope 8, the main rope 18 is wound up to the pair of pulleys 6 by the winch 7, and the pinion 16 is rotated to retract the telescopic guide rod 5 to a position where the pair of pulleys 6 do not interfere with the rotation of the blades 3.

その後、ブレード３を回転させて新たなブレード３を垂直姿勢の状態にし、以下同様にして、新たなメンテナンス作業に入る。
このように、本発明の風力ブレード点検装置は、ナセル２の背上面に固定された巻上げ機構４と、該巻上げ機構４の伸縮ガイド棒５の先端に設けた一対の滑車６と、前記巻上げ機構４の巻上げドラム７から前記滑車６間を介して吊下げられた牽引ロープ８と、該牽引ロープ８の先端に固定されたメンテナンス用ゴンドラ９と、から構成されるため、風力発電装置のブレード３の外周面の塗装、修理等のメンテナンス作業を簡易な構造で短時間に行うことができる。 Thereafter, the blade 3 is rotated to bring a new blade 3 into a vertical position, and a new maintenance operation is started in the same manner.
In this way, the wind blade inspection device of the present invention is composed of a winding mechanism 4 fixed to the upper back surface of the nacelle 2, a pair of pulleys 6 attached to the end of the telescopic guide rod 5 of the winding mechanism 4, a towing rope 8 suspended from the hoisting drum 7 of the winding mechanism 4 between the pulleys 6, and a maintenance gondola 9 fixed to the end of the towing rope 8, so that maintenance work such as painting and repairs on the outer surface of the blades 3 of a wind turbine generator can be performed in a short time with a simple structure.
