Definitions

  • the invention relates to a wind turbine according to the preamble of the claim
  • Wind turbines or wind turbines usually consist of a tower at the upper end of a rotor and a generator connected thereto are arranged.
  • the weight of the rotor and generator is very high, ranging up to 800 tons.
  • this high weight at the top of the tower requires a corresponding mechanical stability of the tower, which significantly increases the construction costs of the wind power plant.
  • DE 10 2008 024 829 B4 and DE-OS 28 17 483 at the top of the tower to arrange only the rotor and the generator in the bottom area of the tower.
  • the rotor shaft at the upper end of the tower is connected to the generator shaft via a traction mechanism drive.
  • the attachment of the at least one generator can be selected in a variety of ways, at a distance from the rotor.
  • the tower can be built easily and high, since the upper end of the tower only has to carry the rotor weight.
  • the tower Since the tower must also carry its own weight and absorb the wind pressure, the tower is designed to be more and more stable towards the bottom, since it has to absorb more and more dead weight. Consequently, it is possible to shift the generator down until the tower has sufficient stability to carry the load of the generator without problems. Since this is still the case in a certain tower height, it is achieved that the length of the traction mechanism drive is shortened.
  • the rotor shaft is also the first traction drive shaft, which means a simplified construction.
  • the traction mechanism drive is designed as a chain drive or toothed belt drive. Slip is excluded in a chain and timing belt drive. In addition, chain drives tend less to undesirable vibrations - claim 7. Similar to toothed belt drives are also traction drives with Kochnemen with nubs and complementary recesses in the wave wheels or wave wheels with knobs or teeth, which engage in complementary recesses in the drive belt, suitable - claim 8.
  • the traction means is tensioned with various measures, so that the power transmission can take place without slippage.
  • the protection of the traction mechanisms can also be achieved in that they extend at least in part - preferably in the lower region - in the interior of the tower.
  • the generator device comprises a plurality of generators which are arranged at different heights of the tower.
  • the provision of a plurality of generators reduces the weight of the individual generators, so that they can be arranged at a greater height without the tower having to become substantially more massive as a result.
  • Due to the advantageous embodiment of the invention according to claim 17 ensures that the rotor with tower can align with the wind and thereby less changing bending moments act on the tower. Due to the lighter construction of the tower, it is possible to anchor the entire tower rotatably in the lower part of the tower with a kind of sleeve.
  • the traction mechanism drives can run on both sides of the tower or according to the advantageous embodiment of the invention according to claim 19 in the upper region on one side and in the lower region on the opposite side.
  • the entire tower is firmly anchored in the ground and the rotor, the generator and the at least one traction mechanism is rotatably mounted on the tower about the tower longitudinal axis. This simplifies the construction, since not the entire tower has to be made rotatable.
  • the rotatable platform according to claim 24 represents a possibility of the rotatable arrangement of the generator.
  • connection of the generator with a turntable according to claim 25 provides an easy way to arrange the generator around the fixed anchored in the ground rotatable.
  • the advantageous embodiment according to claim 26, provides a simple way to curb noise emissions of the generator and to protect the generator from environmental influences.
  • the traction means is guided safely along the tower.
  • the rotational speed of the rotor can be optimally adapted to the generator.
  • the relatively small rotational speeds of the rotor in the range up to 20 rev / min
  • the relatively small rotational speeds of the rotor can be increased and adapted to high-speed generators that produce a high electrical power with small size.
  • the advantageous embodiments according to claim 30 to 35 indicate preferred ranges for the different rotational speeds of the rotor and generator. Due to the advantageous embodiment according to claim 36 friction losses in the at least one traction mechanism drive can be avoided and the susceptibility to defects can be reduced.
  • a pile foundation Due to the advantageous embodiment of claim 39 with a pile foundation, the foundation of the tower in the ground is cheaper. In addition, a pile foundation also allows the construction of a wind turbine on soft or unstable ground.
  • the tower is placed on a carrier pin firmly established in the ground, so that the tower is rotatably mounted on the carrier mandrel.
  • the traction mechanism drive is designed as a chain drive with at least one leaf chain.
  • Leaf chains with a plurality of interconnected links transversely to the direction of movement of the chain are safe and allow the transmission of high power.
  • Chain drives with chain links which are at least partially made of high-strength fiber-reinforced plastic or titanium are particularly advantageous.
  • Suitable plastics are, in particular, polyamide, plastics reinforced with carbon fibers and aramids (for example, Kevlar). It may be the chain drive completely made of high-strength plastic or only the link plates or the chain pins.

Abstract

La présente invention concerne une éolienne dans laquelle le rotor et le générateur sont reliés entre eux au moyen d'une transmission par traction. Le générateur n'est disposé ni à l'extrémité supérieure ni à l'extrémité inférieure du mât, ce qui permet de faire un compromis entre la hauteur du mât et la longueur de la transmission par traction. Le mât peut avoir une construction haute et légère car l'extrémité supérieure du mât ne doit supporter que le poids du rotor.
