Abstract

The Darrieus wind wheel has a rotor (1) similar to the rim of a bicycle wheel with tensioned wire spokes (2) attached to a center tube (3). The rotor is circular and composed of arc sectors so that an approximately rectangular shape with rounded corners results. Spring-loaded flaps or suitable other elements attached to the rotor open at higher revolution rates under centrifugal force to brake the rotor.

Description

Der Läufer (1, Fig. 1 und Fig. 2) des Darrieuswindrades ist wie die Felge eines Fahrrades von gespannten Speichendrähten (2, Fig. 1 und Fig. 2) gehalten, die am Mittelrohr (3, Fig. 1 und Fig. 2) befestigt sind. Der Läufer (1, Fig. 1 und Fig. 2) ist kreisförmig oder so aus Bogenstücken zusammengesetzt, daß eine annähernd viereckige Form mit abgerundeten Ecken entsteht. The rotor ( 1 , Fig. 1 and Fig. 2) of the Darrieus wind wheel is held like the rim of a bicycle by tensioned spoke wires ( 2 , Fig. 1 and Fig. 2) which are attached to the center tube ( 3 , Fig. 1 and Fig. 2 ) are attached. The rotor ( 1 , Fig. 1 and Fig. 2) is circular or so composed of arcs that an approximately square shape with rounded corners.

Am Läufer (1, Fig. 1 und Fig. 2) sind federbelastete Klappen (4, Fig. 1) angebracht, die sich bei hoher Drehzahl des Läufers durch die Fliehkraft öffnen, dabei den Läufer bremsen und dadurch Beschädigung durch zu hohe Drehzahl bei starkem Wind verhindern. On the rotor ( 1 , Fig. 1 and Fig. 2) spring-loaded flaps ( 4 , Fig. 1) are attached, which open at high speed of the rotor due to centrifugal force, thereby braking the rotor and thereby damage due to excessive speed when strong Prevent wind.

Das Drehrohr (5, Fig. 1 und Fig. 2) trägt den Läufer und ist im Standrohr (6, Fig. 1 und Fig. 2) drehbar gelagert. Am Drehrohr sind Spanndrähte (18, Fig. 1 und Fig. 2) angebracht, die das Mittelrohr (3, Fig. 2 und Fig. 2 fixieren und dadurch das Stromlinienprofil (13, Fig. 1 und Fig. 2) des Läufers (1, Fig. 1 und Fig. 2) von Biegekräften entlasten. Das Standrohr (6, Fig. 1 und Fig. 2) ist von Abspanndrähten (19, Fig. 1 und Fig. 2) gehalten. Diese sind bei Aufstellung des Darrieuswindrades an Land im Boden verankert und bei der Offshoreanwendung an der schwimmenden Scheibe (14, Fig. 1) befestigt. The rotary tube ( 5 , Fig. 1 and Fig. 2) carries the rotor and is rotatably mounted in the standpipe ( 6 , Fig. 1 and Fig. 2). Tension wires ( 18 , Fig. 1 and Fig. 2) are attached to the rotary tube, which fix the center tube (3, Fig. 2 and Fig. 2) and thereby the streamline profile ( 13 , Fig. 1 and Fig. 2) of the rotor ( 1st , Fig. 1 and Fig. 2) of bending forces .. The standpipe ( 6 , Fig. 1 and Fig. 2) is held by guy wires ( 19 , Fig. 1 and Fig. 2) which are on land when the Darrieus wind wheel is installed anchored in the ground and attached to the floating disc (14, Fig. 1) during offshore use.

Am Drehrohr (5, Fig. 1 und Fig. 2) sind Magnete (7, Fig. 2), vorzugsweise Permanentmagnete, angebracht. Diese bilden mit den am Standrohr (6, Fig. 2) angebrachten Spulen (8, Fig. 2) einen Generator, der Strom erzeugt. Magnets ( 7 , Fig. 2), preferably permanent magnets, are attached to the rotary tube ( 5 , Fig. 1 and Fig. 2). Together with the coils ( 8 , Fig. 2) attached to the standpipe ( 6 , Fig. 2), these form a generator which generates electricity.

Am Standrohr (6, Fig. 2) ist ein Rammring (9, Fig. 2) angebracht, der zum Einrammen des Standrohres in den Boden dient. Dazu wird von einer Rammvorrichtung (10, Fig. 2) ein teilbares Rammgewicht (11, Fig. 2) mit Rammseilen (12, Fig. 2) laufend hochgezogen und wieder fallengelassen. Das Standrohr (6, Fig. 2) ist am unteren Ende mit einer gehärteten Schneide ausgestattet. Das Standrohr kann gleichzeitig als Mast zur Befestigung der Stromkabel dienen. On the standpipe ( 6 , Fig. 2) a ram ring ( 9 , Fig. 2) is attached, which serves to ram the standpipe into the ground. For this purpose, a ramming device ( 10 , Fig. 2) with a ramming weight ( 11 , Fig. 2) with ramming ropes ( 12 , Fig. 2) is continuously pulled up and dropped again. The standpipe ( 6 , Fig. 2) is equipped with a hardened cutting edge at the lower end. The standpipe can also serve as a mast for attaching the power cables.

Für Offshoreanwendungen ist das Standrohr (6, Fig. 1) auf einer schwimmenden Scheibe (14, Fig. 1) befestigt, die vorzugsweise aus Beton besteht und in der Schwimmkörper (15, Fig. 1) eingeschlossen sind. Zur Gewichtsstabilisierung und zur Verankerung ist an der Unterseite der schwimmenden Scheibe (14, Fig. 1) ein senkrechtes Rohr (16, Fig. 1) und an dessen unterem Ende ein Verstärkungsring (17, Fig. 1) angebracht, die beide vorzugsweise aus Beton bestehen. For offshore applications, the standpipe ( 6 , Fig. 1) is attached to a floating disc ( 14 , Fig. 1), which is preferably made of concrete and is enclosed in the floating body ( 15 , Fig. 1). For weight stabilization and for anchoring, a vertical tube ( 16 , Fig. 1) is attached to the underside of the floating disc ( 14 , Fig. 1) and a reinforcing ring ( 17 , Fig. 1) is attached to its lower end, both of which are preferably made of concrete consist.
