Definitions

  • the invention relates to a wind power installation comprising a horizontally extending rotor axis and a rotor with an axial cross-flow.
  • Such wind power installations are widespread and are employed for opera ⁇ ting machines such as generators or pumps.
  • a good aerodynamic efficiency is achieved by means of wind power installations whose rotors present two or three rotor blades.
  • the task of the present invention consists in developing a wind power installation in such a manner that the wind power is converted into mecha ⁇ nical power to the fullest possible extent and that the lowest possible torque is transmitted to the support of the wind power installation.
  • This task is solved by disposing on the rotor axis two rotors rotating in opposite direction (counterrotating rotors).
  • the rotating movement of both rotors is transmitted to at least one machine, preferably a generator.
  • the torques of each of the two rotors rotating in opposite direction compensate each other, thus not being transmitted to the supporting parts of the wind power installation.
  • the two rotors can be adjusted to one another in such a manner that the kinetic energy of the wind flowing through the profile section of the rotor is drawn to the fullest possible extent. In parti- cular, it is possible to utilize the swirl of the wind flow behind the first rotor by means of the second rotor, converting it into mechanical power.
  • the front rotor comprises three and the rear rotor two rotor blades.
  • the rotor blades of the rear rotor may have a greater length than those of the front rotor.
  • the inner zone of the rear rotor is then driven by the swirl of the outgoing flow of the front rotor, the outer zone of the rear rotor being exposed to the unrestrained wind flow.
  • the shaft of one of the rotors should be executed as a hollow shaft in which extends the shaft of the other rotor.
  • the rotating movements of both of the rotors can be transmitted to the rotor of a generator.
  • the rotating movement of one of the rotors can be transmitted to the stator of the generator und that of the other rotor to the rotor of the generator.
  • the differential gear can be omitted.
  • the rotors are fixed to a housing in which the rotor shafts are mounted.
  • the housing can also contain the generator so that the rotor shafts can be executed extremely short.
  • a wind rudder can be fixed to the housing.
  • the invention also relates to a wind power installation wherein each rotor blade consists of two profiles, curved in the manner of sails and having a concave outer surface directed towards the wind. Thus, a curved flow channel is formed between the two profiles.
  • This arrangement of the rotor blocks is also advantageous in connection with a single-rotor wind power installation.
  • FIG. 1 a front view of the rotors of the wind power installation according to the invention
  • figure 2 a side view of the rotors and of the housing of the wind power installation according to the invention
  • figure 3 a sectional view of a profile of a rotor blade
  • figure 4 the sectional side view of the wind power installation
  • figure 5 a representation of the housing for the rotor shafts of figure 4, viewed in section along sectional line A-A, and
  • FIGS 6 and 7 the front view and the side view, respectively, of an alternative form of execution of the invention.
  • Two counterrotating rotors 1 ,2 are disposed coaxially on the wind power installation.
  • the first one, the front rotor 1 going by the direction of flow, comprises three rotor blades 3.
  • the second one, the rear rotor 2 going by the direction of flow, comprises two rotor blades 4.
  • the rotor blades 4 of the rear rotor 2 have a greater length than the rotor blades 3 of the front rotor 1.
  • the shafts 8,9 of both of the rotors 1 and 2 are mounted rotatably in a housing 5 by means of rolling bearings 6 and 7 (see figure 4) .
  • the shaft 8 of rotor 1 is formed by a hollow shaft.
  • the shaft 9 of rotor 2 extends inside said hollow shaft.
  • the shafts 8 and 9 are connected to a generator 13 by means of a differential gear 10 and intermediate shafts 11 and 12.
  • Inter ⁇ mediate shafts 1 1 and 12 which are also formed by a hollow shaft 1 1 and a shaft 12 located inside the hollow shaft, are rotatably connected with the rotor shafts via bevel gears 14, 15, 16, 17.
  • the differential gear 10 is executed in such a manner that the torques of 5 both of the rotors 1 and 2 act jointly on the shaft 18 of the generator 13 , forming a sum there.
  • the torques of both of the rotors which can be different depending on wind velocity, contribute entirely to the generation of power.
  • the differential gear 10 consists of bevel gears on the extremities of the differential shafts 11 and 12 both of which act upon a bevel gear on generator shaft 18.
  • housing 5 is provided with a wind rudder 19.
  • Housing 5 is fixed rotatably to a hollow housing support 21 which contains the intermediate shafts 11 and 12 by means of a rolling bearing 20.
  • a housing support 21 of sufficient length, it is possible to dispose the rotors 1 and 2 at a sufficient distance from the ground so that in the area of the rotors the 20 wind flow is not disturbed by ground friction.
  • the housing 5 is executed in a streamlined shape, with a rounded or pointed extremity facing the wind.
  • All the rotor blades of the rotors 1 , 2 preferably each consist of two 25 profiles 22, 23 curved in the manner of sails and forming a concave outer surface 24 directed towards the wind and a curved flow channel 25.
  • the flow profiles of the rotors 1 and 2 are oriented in such a manner that the rotors 1 and 2 run in opposite directions of rotation. A sectional view of such a rotor profile is shown in figure 3.
  • FIGS. 6 and 7 show an alternative form of execution of the invention.
  • the shaft 8 of the front rotor 1 is fixed to the housing of the generator 13.
  • the shaft 9 of the rear rotor 2 is fixed to the rotor of the generator 13.
  • the generator 13 is arranged within the housing 5 of the wind power installa ⁇ tion.
  • the differential gear can be omitted, the entire wind power installation with its power generating unit being disposed inside the housing

Abstract

L'invention concerne une éolienne comprenant un axe de rotor s'étendant horizontalement ainsi qu'un rotor présentant un courant tangentiel. Le problème posé consiste à atteindre une vitesse élevée de conversion de l'énergie du vent en énergie mécanique et à minimiser le couple transmis au support de l'éolienne. Afin de résoudre ce problème, on a disposé, sur l'axe du rotor, deux rotors à rotation antagoniste, le mouvement tournant des deux rotors étant transmis au moins à une machine, de préférence un générateur.
