Abstract

A multiple wind turbine structure in the form of a fixed television mast disposes the turbines in pairs supported on bearings which enable their independent 360 deg rotation about the mast to give alignment with the wind direction. Large diameter rotors are stabilised by having blades which are braced via front and rear radial struts (9) in conjunction with a support ring (8) concentric with the axis and housing of its generator. Various sizes of rotor are proposed to enable optimal use of space and suitable materials include carbon fibre-reinforced plastics, aluminium alloy, steel, concrete, etc.

Description

Es ist bekannt, daß mehrere Windräder durch Aneinanderreih­ ung an einen Turm platzsparend zusammengefaßt sind (P 29 41 778.5-15). Dabei ist es allerdings zur Ausrichtung der Räder nach dem Wind nötig, große Teile des Turmes an denen mehr­ ere Windradpaare befestigt sind zu drehen, weil die einzel­ nen Windradpaare nicht 360 Grad um ihre Hochachse drehbar sind. Das verhindert eine größere Stabilität der Türme und eine schnellere Ausrichtung der Windräder. Ferner sind die Rotoren nicht mit Halterungen ausgestattet, was keine grö­ ßeren Rotordurchmesser ermöglicht.It is known that several wind turbines are lined up are combined to save space on a tower (P 29 41 778.5-15). However, it is to align the wheels necessary after the wind, large parts of the tower on which more ere wind turbine pairs are attached to rotate because the single pairs of wind turbines cannot be rotated 360 degrees around their vertical axis are. This prevents greater stability of the towers and faster alignment of the wind turbines. Furthermore, the Rotors not equipped with brackets, which is not a big allows outer rotor diameter.

Der im Patentanspruch angegebenen Erfindung liegt das Pro­ blem zugrunde, möglichst viele Windräder zu einem Komplex zu vereinen und sie sehr groß zu gestalten, ohne daß die Stabilität der Windräder und des Turmes zweifelhaft wird, wobei jedes Windradpaar individuell nach jeder Windrichtung ausgerichtet werden kann.The invention specified in the claim is the pro underlying, as many wind turbines as possible to a complex to unite and make them very large without the Stability of the wind turbines and the tower becomes questionable, each pair of wind turbines individually according to each wind direction can be aligned.

Dieses Problem wird durch die in den Patentansprüchen auf­ geführten Merkmale gelöst.This problem is highlighted in the claims guided characteristics solved.

Die mit der Erfindung erzielten Vorteile bestehen insbeson­ dere darin, daß viel Platz durch eine relativ geringe Standfläche eingespart wird, was für die Landschaftsästhe­ tig günstig ist, und daß durch die größere Turmstabilität 1. mehr und 2. größere Windräder verwendet werden können.The advantages achieved with the invention are in particular the fact that a lot of space by a relatively small Stand space is saved, what for the landscape aesthetics tig is cheap, and that by the greater tower stability 1. more and 2. larger wind turbines can be used.

Eine vorteilhafte Ausgestaltung der Erfindung ist, das Komplexwindkraftwerk als Fernsehturm zu bauen.An advantageous embodiment of the invention is that To build a complex wind power station as a television tower.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnung­ en dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention is in the drawing s and is described in more detail below.

Der Windradturm (1) ist nicht drehbar, sondern fest veran­ kert. Jeweils zwei, den ganzen Turm umfassenden Kugellager (2), ermöglichen eine unabhängige 360 Grad- Drehung jedes Windradpaares. Die Rotoren der Windräder haben bis zu 50 m Durchmesser. Sie werden durch verschiedene Rotorhalterungen vor einer Bruchgefahr geschützt. Und zwar erhalten die Windräder mittlerer Größe die Halterung, welche in Fig. 2 dargestellt ist. Sie besteht aus Vorderstangen (3), die einerseits an den Rotorblättern, und andererseits am Ende einer verlängerten Rotorwelle (4) befestigt sind und aus Hinterstangen (5), welche ebenfalls einerseits an den Ro­ torblättern, aber andererseits an einem Kugellager (6) be­ festigt sind, welches das Getriebe- bzw. Generatorgehäu­ se umfaßt. Damit dieses Kugellager sich problemlos immer genau so schnell wie der Rotor dreht, ist der Spinner durch eine Verlängerung (7) mit ihm verbunden. Somit wird die Drehbewegung des Rotors zusätzlich über einen kürzeren Weg als über die Stangen auf das Kugellager übertragen. Durch den Einsatz von Vorder- und Hinterstangen können diese re­ lativ dünn sein, da sie, egal ob der Wind von vorne oder von hinten weht, in der Hauptsache auf Zug belastet werden. Aus diesem Grund kann man bei kleineren Rädern die Stangen durch Seile ersetzen. Da bei kleineren Windrädern die Bie­ gemomentbelastung der Rotorwelle keine kritische Ausmaße erreicht, ist eine von der Rotorwelle unabhängige drehbare Stütze, sprich Kugellager überflüssig. Deshalb ist für das kleinste Windradpaar des Komplexes eine Halterung mit Seilen und ohne stützendes Kugellager ausreichend. Für die größten Räder (50 m Durchmesser) ist eine andersartige Hal­ terung vorgesehen. Und zwar besteht diese aus einem Stütz- und Haltering (8), mehreren Haltearmen (9), sowie aus mehr­ eren Stütz- und Maltestangen (10), welche mit je einer Ach­ se und zwei Laufrollen (11) ausgerüstet sind. Der Stütz- und Haltering wird mit seinen Haltearmen am Generatorgehäu­ se so befestigt, daß er höchstens zehn Zentimeter vom Ro­ tor entfernt ist. Die Rotorblätter werden an ihren Rücksei­ ten (etwa in halber Höhe) mit je einer Stütz- und Halte­ stange ausgerüstet, welche mit den Enden, an denen sich die Laufrollen befinden, in den Haltering hineinragen. Die Rol­ len stützen über ihre Achsen und Haltestangen die Rotor­ blätter, während sie über die beiden Stützlaufbahnen 12, und halten die Rotorblätter, während sie über die beiden Haltelaufbahnen (13) rollen. Die an mindestens einer Halte­ stange befestigte Bremsen reiben beim Bremsen über die mit (14) gekennzeichneten Ringe. Die Wandabweiserrollen (15) verhindern eine Berührung der Haltestangen mit dem Halte­ ring und damit einen Abrieb, sowie eine unerwünschte Bremse. Als Materialien sind Kohlefaserverstärkte Kunststoffe, Aluminiumlegierungen, Stahl und Beton geeignet.The wind turbine tower ( 1 ) is not rotatable, but anchored firmly. Two ball bearings ( 2 ) encompassing the entire tower enable each pair of wind turbines to rotate independently by 360 degrees. The wind turbine rotors are up to 50 m in diameter. They are protected against breakage by various rotor brackets. Namely, the medium-sized wind turbines receive the holder, which is shown in Fig. 2. It consists of front rods ( 3 ), which are fastened on the one hand to the rotor blades, and on the other hand at the end of an elongated rotor shaft ( 4 ) and from rear rods ( 5 ), which are also on the one hand on the rotor blades, but on the other hand on a ball bearing ( 6 ) are consolidated, which includes the gearbox or generator housing. The spinner is connected to it by an extension ( 7 ) so that this ball bearing always turns as quickly as the rotor without any problems. Thus, the rotary movement of the rotor is also transmitted to the ball bearing over a shorter path than via the rods. Through the use of front and rear poles, these can be relatively thin, since, regardless of whether the wind is blowing from the front or from behind, they are mainly subjected to tension. For this reason, the rods can be replaced by ropes on smaller wheels. Since the bending moment load of the rotor shaft does not reach critical dimensions in the case of smaller wind turbines, a rotatable support that is independent of the rotor shaft, that is, ball bearings, is superfluous. Therefore, a bracket with ropes and without supporting ball bearings is sufficient for the smallest pair of wind turbines in the complex. For the largest wheels (50 m diameter) a different type of maintenance is provided. Namely, this consists of a support and retaining ring ( 8 ), several holding arms ( 9 ), as well as more support and painting rods ( 10 ), each of which is equipped with an axle and two rollers ( 11 ). The support and retaining ring is attached with its holding arms to the generator housing so that it is at most ten centimeters from the rotor. The rotor blades are equipped on their rear sides (approximately halfway up) with a support and holding rod, which protrude into the retaining ring with the ends on which the rollers are located. The Rol len support the rotor blades via their axes and support rods, while they are on the two support tracks 12 , and hold the rotor blades as they roll over the two support tracks ( 13 ). The brakes attached to at least one support rod rub when braking over the rings marked with ( 14 ). The wall deflector rollers ( 15 ) prevent the holding rods from touching the holding ring and thus wear, as well as an undesirable brake. Carbon fiber reinforced plastics, aluminum alloys, steel and concrete are suitable as materials.
