Definitions

  • the invention relates to a wind turbine.
  • the known wind turbines consist of a tower which carries a rotor with several rotor blades.
  • a generator which generates the electrical energy, is coupled to the rotor via a transmission gear.
  • Power plants with several wind turbines are also referred to as wind farms.
  • the tower In order to be able to use the higher wind speed at higher altitudes, the tower should have a large construction height.
  • the construction of a high tower is associated with considerable technical effort, especially since the heavy generator of the known wind turbines arranged on the tower head requires a very stable structure. Plants with an output of up to around 200 KW are built in a tubular steel structure. Larger systems use a reinforced concrete tower as the supporting structure.
  • a further disadvantage of the known wind turbines is that a minimum wind speed is required to turn the rotor.
  • the object of the invention is to create a wind power plant whose tower or its foundation can be constructed in a simple manner with relatively little effort.
  • the power on the rotor shaft is transferred hydraulically to the generator.
  • the rotor advantageously drives a hydraulic pump which is connected via pressure medium lines to a hydraulic motor driving the generator.
  • the hydraulic power transmission makes it possible to place the very heavy generator on the ground in a machine house. As a result, the main load of the tower is reduced, so that an easier and less expensive design of the tower and the foundation is possible. In this way, towers with a large overall height can be erected with relatively little effort and the performance of the system increased.
  • the hydraulic pumps assigned to the individual rotors can be switched to a common hydraulic motor.
  • wind energy can be optimally used even at low wind speeds.
  • the hydraulic pumps Pen of the individual rotors together drive a generator with the optimal speed or the optimal torque.
  • the tower can be tilted from the horizontal position into the vertical position, preferably with a hydraulic drive.
  • a crane for erecting the tower mounted on the floor is therefore not necessary.
  • the tower is a tube construction made of tubes that run obliquely upwards with horizontal struts.
  • the essentially vertical tubes of the tower consist of individual tube segments that can be assembled telescopically and are delimited by stops.
  • the horizontal struts of the tubular construction form an angular frame, at the corner points of which tubular connecting pieces are provided which enclose the tubular segments and hold the vertical tubes together firmly.
  • the tower can be assembled on site in the manner of a modular system from the tube segments and the angular frame.
  • the individual parts can be assembled into towers of different heights. They can also be transported to the installation site with smaller vehicles. Heavy transporters for the transport of larger assembly units are therefore not necessary.
  • the foundation of the tower can also be built in a simple manner. To erect the foundation, it is only necessary to drill holes in the ground into which a suitable filler material is injected.
  • the wind forces acting on the tower are advantageously intercepted with lateral arms which are attached to the foundation heads.
  • the cantilevers are connected at their free ends to bases, from which, in turn, foundation strands formed in the manner of a root extend into the ground.

  • Shut-off valves 11, 11 ', 11 are provided in the pressure medium lines 6, 6', 6" between the hydraulic pumps and hydraulic motors.

Abstract

Une installation fonctionnant à l'énergie éolienne comprend un mât (2) qui porte un rotor (3) qui actionne un générateur (8). La puissance au niveau de l'arbre du rotor est transmise au générateur de manière hydraulique. Le rotor actionne avantageusement une pompe hydraulique (5) reliée par l'intermédiaire de conduites hydrauliques à un moteur hydraulique (7) qui actionne le générateur. Le système de transmission hydraulique permet de placer le générateur (8) qui est très lourd sur le sol d'un hall de machines. L'invention permet de diminuer la charge principale du mât, de manière à pouvoir parvenir à une conception plus légère et plus économique du mât et de ses fondations. Pour les centrales qui comprennent plusieurs installations fonctionnant à l'énergie éolienne (1, 1', 1''), les pompes hydrauliques (5, 5', 5'') associées aux rotors (3, 3', 3'') individuels peuvent être commutées sur un moteur hydraulique (7, 7', 7'') commun, ce qui permet d'utiliser deanière optimale l'énergie éolienne, y compris pour des vitesses de vent réduites.
