Description
本発明は、風力発電装置の安全装置に関する。 The present invention relates to a safety device for a wind turbine generator.
従来のプロペラ式風力発電装置は、暴風時の安全対策機能として、プロペラのピッチを変える、プロペラにブレーキをかける、プロペラが風を正面から受けないように横に振らすなどの方法がある。 Conventional propeller-type wind power generators include methods such as changing the pitch of the propeller, braking the propeller, and shaking the propeller so that it does not receive wind from the front, as a safety measure function in case of a storm.
以上に述べた従来の風力発電装置の安全手段では、暴風時や台風時の安全対策として十分ではなく、常に機器の破損やプロペラなどの部品が風で飛ばされて通行人や建物に直撃するなどの恐れがある。 The safety measures of the conventional wind power generators described above are not sufficient as safety measures during storms and typhoons, and damage to equipment and parts such as propellers are always blown by the wind and directly hit passers-by and buildings. There is a fear.
又、風力発電装置は風の強い場所に設置されることが多く、プロペラが風圧を受けやすいことなどから有効な安全装置の開発が待ち望まれている。 In addition, wind power generators are often installed in windy places, and the development of effective safety devices is awaited because the propellers are susceptible to wind pressure.
本発明は、このような従来の構成が有していた問題を解決しようとするものであり、台風時にも安全、安心な風力発電装置を実現することを目的とするものである。 The present invention is intended to solve the problems of such a conventional configuration, and an object of the present invention is to realize a wind power generator that is safe and secure even during a typhoon.
風力発電装置の支持部材に折れ曲がる構造を持ち、支持部材が折れ曲がった状態で下に構築したプロペラカバーに収まる構造にする。 It has a structure that bends to the support member of the wind power generator, and has a structure that fits in the propeller cover constructed below with the support member bent.
プロペラカバーには、プロペラ軸先端に取り付けたコーンがピッタリ入る窪みを設け、プロペラカバーとプロペラ軸をしっかりと連結する。 The propeller cover is provided with a recess to fit the cone attached to the tip of the propeller shaft, and the propeller cover and the propeller shaft are firmly connected.
上記の構造により、暴風時には、風圧を受けやすいプロペラをカバーに収納することでプロペラの破損や飛び去りを防止出来る。 With the above structure, it is possible to prevent the propeller from being damaged or flying away by storing the propeller that is easily subjected to wind pressure in the cover during a storm.
又、プロペラが地面に対して垂直から水平状態になることと、構造物の高さが低くなることから横風を受けにくくなり、破損や部品飛び去りに対して有効である。 In addition, since the propeller changes from a vertical state to a horizontal state with respect to the ground and the height of the structure is lowered, it is difficult to receive a cross wind, which is effective against damage and part skipping.
さらに、プロペラコーンをプロペラカバーとその構造物で支えるので、２つの構造物が暴風時には一体となって、支えあい通常状態より構造上強固である。 Further, since the propeller cone is supported by the propeller cover and its structure, the two structures are united and supported in a storm and are structurally stronger than the normal state.
以下、本発明の実施の形態を図１、図２を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
図２は、通常の発電状態で、プロペラ１と発電機３は、常に風上を向いてプロペラ１を回すタイプの風力発電装置である。 FIG. 2 shows a wind power generator of a type in which the propeller 1 and the
プロペラカバー２は、プロペラ１を収納するためのもので、中央にはプロペラ軸先端にあるプロペラコーン６を受ける窪みがある。 The propeller cover 2 is for housing the propeller 1, and has a recess for receiving the propeller cone 6 at the tip of the propeller shaft at the center.
台風時や想定以上の風速を検知、予測できる時には、本発明である次の動作を行う。 When typhoons or wind speeds higher than expected can be detected and predicted, the following operations according to the present invention are performed.
まず、通常発電状態である図２においてプロペラ１をストップし発電機３は、あらかじめ決めた方位に向ける。 First, in FIG. 2, which is a normal power generation state, the propeller 1 is stopped and the
次に、油圧シリンダー４を収縮することによって、風力発電装置の支持部材は可動部５から折れ曲がる。 Next, the support member of the wind turbine generator is bent from the
９０度まで折れ曲がった状態が図１である。この状態でプロペラ１はプロペラカバー２に収まり、横風や強風によって飛ばされた物から保護される FIG. 1 shows a state bent to 90 degrees. In this state, the propeller 1 fits in the propeller cover 2 and is protected from things blown by crosswinds or strong winds.
この状態で、プロペラ１のプロペラコーン６は、プロペラカバー２の窪みにしっかりと、はまり込んで固定される。このために、従来からの風力発電装置を本発明の特色であるプロペラカバーの構造物が支える形になり、従来の単独状態より構造上強固である。 In this state, the propeller cone 6 of the propeller 1 is firmly fixed in the recess of the propeller cover 2. For this reason, the conventional wind power generator is supported by the structure of the propeller cover, which is a feature of the present invention, and is structurally stronger than the conventional single state.
さらに、図２の風力発電装置が立ち上がった状態より、図１の上部が９０度折れ曲がった状態の方が台風などで想定される横風に対して、風圧を受けにくいので、破損や部品飛び去りのリスクを減らすことが出来る。 In addition, the wind power generator shown in FIG. 2 is bent 90 degrees at the top of FIG. 1 because it is less susceptible to wind pressure against the crosswinds assumed for typhoons, etc. Risk can be reduced.
天候が回復した時は、油圧シリンダー４を伸ばし風力発電装置を起こして、図２の状態に戻り、速やかに発電動作にはいることが可能である When the weather recovers, it is possible to extend the hydraulic cylinder 4 and raise the wind power generator to return to the state of FIG.
