Definitions

  • the invention relates to a wind power plant for utilizing wind energy, in particular for generating electrical current and for driving supply devices and working machines, according to the preamble of patent claim 1.
  • a known wind turbine wheel (DE-I 925 200) has a rotor cone, from the circumferential surface of which rotor blades distributed radially protrude. The cone base surface is closed and the freely projecting blades are so close together that they still overlap.
  • a rotatably mounted cone jacket carries radially projecting blade rings, which optionally extend in the form of spiral ribs from the tip to the base of the cone and also relatively far radially outwards stand out.
  • Air channels are formed between the spiral ribs, which, with guide blades, form spiral vessels with adjoining nozzles, so that the air emerging from these cone channels impacts a fixed ring of ribs through the nozzles and thereby triggers a turbo effect.
  • These known wind turbines usually do not meet the requirements to be placed on a wind power plant. It should namely, sufficient power can already be achieved in weak winds and at the same time there is no excessive drop in efficiency in strong winds. The system should also not break due to excessive rotor speed. Finally, it has been shown in the known rotors that their speeds change very strongly during gusts.
  • the invention is therefore based on the object of providing a wind power plant which produces an increased and uniform output both in weak and in strong, gusty winds and also has a simple and robust construction.
  • the conical jacket sets the air layer along its surface in a co-rotating motion in the form of a swirl. In addition to the smooth design, this ensures that the air flow does not enter the hollow wing. Even strong gusts do not change this, since excess air masses cannot attack the rotor.
  • FIG. 1 shows a side view of a wind power plant
  • FIG. 2 shows an end view of a partially drawn wind rotor
  • FIG. 3 shows a side view of this wind rotor with drawn flow lines.
  • a wind rotor 1 according to the invention is mounted on a tower, scaffolding or standpipe 2, its rotor axis 3, which is set essentially horizontally, being mounted in axle bearings on a turntable (not shown).
  • the rotor can be adjusted to the wind direction automatically by means of a wind vane 4 or by other mechanical or automatic control devices.
  • the rotational movement is derived from the rotor axis 3 downwards by means of an angular gear 5 via a shaft 6, which can be mounted in the hollow standpipe, to a ground gear 7, for example with a PTO shaft connection 8.
  • a clutch 9 enables the drive to be disconnected.
  • the rotor with the wind vane can be conveniently folded down to the ground.
  • the wind rotor 1 has a cone jacket 10, which is closed at its tip 11 directed against the wind and also carries a wind guide ring 13 on its jacket base 12, the jacket surface of which runs approximately parallel to the rotor axis.
  • the conical rotor body is open at its base surface. Disturbing flow vortices are largely avoided by the wind control ring.
  • From the circumferential surface 10 of the rotor project radially outwardly extending vanes 15, which with their inner edge 16 expediently extend from the circumferential base 12 in the direction of the cone tip 11.
  • These wings are expediently rectangular so that an outer jacket 20 covering the outer edges 17 of these wings runs parallel to the cone jacket 10.
  • the length of the outer jacket is advantageously as large as the extent of the more or less curved wings along a jacket line, * so that the wings are completely covered when viewed in the jacket plane.
  • a length-to-height ratio of the vanes that has proven itself in practice is approximately 2: 1.
  • the outer jacket can in turn take up approximately one third of the conical jacket.
  • the wings are arranged according to aerodynamic aspects, for which purpose they can also be curved in an arc and set at an angle to the wind flow. If the longitudinal edges 16, 17 of the wings do not run parallel to one another, widening or narrowing flow channels 21 can be created as a result.
  • the wind vane 4 can be rotated about the horizontal axis, so that the rotor can be stopped by unscrewing it from the wind.
  • the wings and the outer casing can be solid or hollow bodies with a cross-sectional shape that is favorable in terms of flow. It can also be advantageous here if the outer surface of the outer jacket is slightly curved, while the inner surface is flat.

Abstract

Une éolienne est équipée d'un rotor (1) en forme de cône dont l'enveloppe (10) conique est pourvue de plusieurs pales (15) en saillie radiale et réparties sur son pourtour, les extrémités desdites pales étant recouvertes d'une enveloppe extérieure (20). Ainsi, des canaux d'écoulement (21) du courant de vent sont ménagés sur une section de l'enveloppe conique.
