Abstract

The fire detection system is for a windmill e.g. with a propeller-type rotor (2) connected to a machine housing (1) containing drive gears and an electrical generator. There are two fire detectors (3,4) in the machine housing. The first is sensitive to heat and light throughout the whole 360 degree arc and the second looks toward the rotor and may be sensitive only through a 90 degree arc.

Description

Aufgrund der baulichen Gegebenheiten einer Windenergieanlage ist es erforderlich Nachtkennzeichnungssystemen (3, 4) in doppelter Ausführung auf dem Maschinenhaus (1) der Anlagen zu installieren. Durch den rotierenden oder stillstehenden Rotor (2) der Windenergieanlage kann es zu einer Verdeckung eines Feuers kommen, so dass aus diesem Grund auf dem Maschinehaus zwei Feuer in ausreichendem Abstand zu installieren sind. Die Doppelung der Feuer führt aber auch dazu, dass beide Feuer 360° in horizontaler Richtung doppelt abstrahlen, obwohl dieses nicht erforderlich wäre. Es wird ein Gebrauchsmuster für ein Nachkennzeichnungssystem für Windenergieanlagen beantragt, welches nur in die Richtung des Rotors doppelt ausgelegt ist.Due to the structural conditions of a wind turbine, night marking systems ( 3 . 4 ) in duplicate on the nacelle ( 1 ) to install the systems. The rotating or stationary rotor ( 2 ) the wind turbine may be covered by a fire, so that for this reason two fires must be installed at a sufficient distance on the nacelle. The doubling of the fires also means that both fires radiate twice 360 ° in the horizontal direction, although this would not be necessary. A utility model for a post-marking system for wind turbines is requested, which is only designed twice in the direction of the rotor.

Eines der beiden Feuer (4) wird in dem horizontalen Abstrahlungswinkel soweit reduziert, dass durch den drehenden oder stillstehenden Rotor es nicht zu einer Total-Verdeckung des Nachtkennzeichnungssystemen kommen kann. Durch die Reduzierung des Abstrahlungswinkel bei einem der beiden Feuer wird in die verbleibenden Richtungen nur von einem der beiden Feuer Licht abgestrahlt.One of the two fires ( 4 ) is reduced in the horizontal radiation angle to such an extent that the rotating or stationary rotor does not result in total obscuration of the night marking system. By reducing the radiation angle of one of the two fires, only one of the two fires radiates light in the remaining directions.

Der Nutzen des „Nachtkennzeichnungssystem für Windenergieanlagen" liegt darin, bei ausreichender Nachtkennzeichnung der Windenergieanlage eine technische Lösung für die Reduzierung der Lichtemission gefunden zu haben.The benefits of the “night labeling system for wind turbines "is included sufficient night labeling of the wind turbine a technical solution for the Have found reduction in light emission.

Claims (1)

Das Nachtkennzeichnungssystem für Windenergieanlagen ist dadurch gekennzeichnet, dass die Feuer (3, 4) auf dem Maschinenhaus (1) nur in die Richtung des Rotors (2) doppelt ausgelegt sind. Eines der Feuer (4) ist im horizontalen Abstrahlwinkel so ausgelegt, dass eine Lichtabstrahlung nur in die Richtung des Rotors möglich ist.The night marking system for wind turbines is characterized in that the fires ( 3 . 4 ) on the machine house ( 1 ) only in the direction of the rotor ( 2 ) are designed twice. One of the fires ( 4 ) is designed in the horizontal beam angle so that light can only be emitted in the direction of the rotor.
