Definitions
- the invention relates to a device for converting water or wind energy with a rotor which can be rotated about a preferred vertical rotor axis of rotation and which carries two or more guide profiles rotatably mounted on the rotor, the angle which each guide profile includes with the rotor being greater than a control device can be set, the control device having a preferably ring-shaped element which also rotates with the rotor and from which control rods lead outwards to the guide profiles.
- Such wind or water wheels are often operated with a vertical rotor axis and generally have streamlined guide profiles.
- a rotor is, for example, the Darrieus rotor or a modification thereof with straight guide profiles (H rotor).
- the Darieus rotor is described, for example, in US Pat. No. 1,835,018.
- a control device consisting of an eccentric, annular element and control rods is provided in order to continuously change the angle of the guide profiles relative to the rotor during the rotation.
- US Pat. No. 1,835,018 does not provide any information about the precise guidance of the annular eccentric element.
- the Darrieus rotor also functions when the guide profiles are always oriented tangentially to the wind, as is the case with the embodiment described in FIG. 2 of US Pat. No. 1,835,018.
- this embodiment requires external help to start up, because only at a certain speed can the wind generate torque due to the inflow conditions on the guide profiles.
- the object of the invention is to provide a device for converting water or wind energy of the type mentioned at the beginning, with which an optimal adaptation to the strength of the flow and / or the direction of the flow is possible.
- the device is characterized by an adjusting device for adjusting the position of the axis of rotation, about which the preferably annular element rotates, relative to the axis of rotation of the rotor.
- the device according to the invention is particularly suitable.
- the device according to the invention is in principle also suitable for converting water energy or any other flowing medium.
- the preferably ring-shaped element which is generally arranged near the axis of rotation of the rotor, rotates at the same peripheral speed as the rotor, and is therefore also co-rotating with it.
- the position of the axis of rotation of the preferably annular element can preferably be adjusted relative to the position of the axis of rotation of the rotor, so that these two axes of rotation do not necessarily coincide, but generally there is an eccentricity of the annular element with respect to the axis of rotation of the rotor.
- This eccentricity has the effect that the guide profiles connected to the preferably annular element via control rods constantly change their relative angle to the rotor during their rotation and thus allow optimal use of wind energy.
- the guide profiles join can assume deviating angles relative to the tangential position of their orbit at the point of the orbit facing the wind and away from the wind. Later, when the rotor has reached its nominal speed, the guide profiles can then be made absolutely tangent so that they do not change their relative angle to the rotor as they rotate.
- the ring-shaped element from which the control rods lead to the guide profiles need only be adjusted so that its axis of rotation coincides with the axis of rotation of the rotor, whereby the eccentricity disappears. With a corresponding length of the control rods, one can then set an exact tangential position of the guide profiles in relation to their orbit.
- the change in the guide profile position described can take place as a function of the rotor speed, in particular via a centrifugal force regulator which, depending on the rotor speed, adjusts the distance between the axis of rotation of the rotor and the axis of rotation of the preferably annular element (that is, the extent of the eccentricity).
- a setting parameter is the extent of the eccentricity, ie the distance between the axis of rotation of the rotor and the axis of rotation of the preferably ring-shaped element.
- Another parameter which characterizes the position of the axis of rotation of the preferably annular element relative to the axis of rotation of the rotor, consists in the position of the imaginary connecting line between the
- Axis of rotation of the rotor and the axis of rotation of the preferably annular element relative to the wind direction which is generally not fixed.
- a guide which rotates the preferably co-rotating with the rotor leads shaped element is connected to a ring vane and is oriented relative to the wind direction by this.
- This orientation of the guide means that the position of the imaginary connecting line between the axis of rotation of the rotor and the axis of rotation of the preferably annular element relative to the wind can be set automatically.
- FIG. 1 shows a schematic longitudinal section through an exemplary embodiment of a device according to the invention in the form of a wind turbine.
- Fig. 2 shows a schematic plan view of an embodiment of a device according to the invention in cal atic representation.
- 3 shows a longitudinal section through the central area of an embodiment of a wind turbine according to the invention.
- FIG. 4 shows an alternative embodiment in a schematic top view.
- FIGS. 1 and 2 The wind turbine shown in FIGS. 1 and 2 appears on a rotor 1, which is rotatably mounted on a stand 3 about an axis of rotation 2.
- a generator or the like can then be used. Electrical energy can be obtained. But it is also possible to use mechanical transmission chains or the like. to operate any machines, pumps, etc. directly mechanically.
- the rotor 1 carries in its outer region four streamlined guide profiles 4 which are rotatably mounted on the rotor relative to the latter, the ring adjustment is set relative to the rotor via control rods 5.
- the control rods 5 are fastened on the inside to a preferably annular element 6 which also rotates with the rotor 1.
- This annular element 6 is guided through a non-rotating part 7, along the circumference of which the preferably annular element 6 can rotate.
- the position of the disk-shaped part 7 thus defines the position of the axis of rotation 8 of the preferably annular element 6.
- a roller bearing or the like can also be used in between. be arranged, as will be described in connection with FIG. 3.
- the location of the Scheiber. shaped part 7 and thus the position of the axis of rotation 8 of the preferably annular element 6 is now adjustable according to the invention in two respects.
- the distance of the axis of rotation 8 of the preferably annular element 6 from the axis of rotation 2 of the rotor 1 can be set.
- the position of the imaginary connecting line 9 between the two axes of rotation 2 and 8 can be aligned relative to the wind direction 10.
- Guide profiles 4 from the precisely tangential position to their orbit.
- the start-up phase is shown in FIGS. 1 and 2.
- the preferably ring-shaped element rotates eccentrically to the axis of rotation 2 of the rotor, with the result that the guiding profiles are primarily oriented towards the wind the opposite side of the rotor and the side facing away from the wind and thus assume a position relative to the wind 10 which is more favorable with regard to the generation of a torque. If the rotor then begins to turn, the flow conditions change due to the movement of the guide profiles and it is then more favorable if all guide profiles are always tangential.
- the degree of eccentricity of the ring-shaped element 6 is simply reduced to zero with respect to the axis of rotation of the rotor 1, with which the two axes of rotation 2 and 8 coincide.
- This adjustment is achieved by moving the disc-shaped part 7 horizontally. The whole thing is controlled via the centrifugal force controller 11 as a function of the speed of the rotor 1. As the speed of the rotor 1 increases, the weights 12 move outwards. This pivoting movement is then transmitted via pinion 13 to a lifting movement of the rod 14.
- the rack section 14a of the rod 14 rotates a pinion 15 which engages in a rack section 7a on the disk-shaped part 7 and this Moves part to the axis of rotation 2 of the rotor.
- Fig. 4 shows an alternative embodiment in which the guide profiles are made in two parts.
- a guide profile part 4a is always aligned in the same position relative to the rotor 1.
- a second part 4b is rotatably mounted on this part 4a and can be adjusted via the control rods 5 in the manner of a rudder.
- the arrangement, number and design of the master profiles can differ from the exemplary embodiments shown. It is also possible to use the centrifugal force regulator 11 instead of the adjustment of the preferably annular element, for example perform an electric motor that could be controlled depending on an external wind measurement system.
- the non-rotating part 7 can also be aligned relative to the image in principle instead of the direct mechanical alignment using a wind vane, in which case input signals from an external wind measurement system can be rotated.
