Description

Device in the manner of a wind turbine

The invention relates to a device of the type of a wind turbine for harnessing the energy contained in an air stream, which is equipped with an inner rotor cylinder, which has acted upon by the air blades and is used to drive a power generator.

Such devices are known. DE 19623055 A1 describes a wind turbine with an inner rotor cylinder with blades, which is surrounded by an outer fixed guide cylinder with vanes. The wind turbine is placed in the wind so that the inflowing air flow meets transverse lamellae transverse to the rotor axis. These direct the inflowing air to the rotor blades of the rotor cylinder and set this in motion. The surrounding the blades of the rotor cylinder vanes have the purpose to supply the blades to the air in a constant blowing angle as possible.

In the known devices, all air that does not directly affect the uniform cylinder curvature flows off unused.

It is an object of the invention to improve a device of the known type such that even the side of the cylinder curvature flowing air stream, which flows away unused sideways, is used to drive the rotor cylinders. It should, as far as possible, even in the shadow behind the turbine arrangement still incoming air are collected.

The stated object is achieved according to the invention with two embodiments, as described in more detail by the independent claims.

Preferred embodiments are subject of the dependent claims or described below.

The first embodiment consists of a device such as a wind turbine for harnessing the energy contained in an air flow, with a cylindrical wind turbine, which is equipped

CONFIRMATION COPY - With an inner rotor cylinder, which has acted upon by the air blades and in particular serves to drive a rotating power generator, wherein the blades may also have a helical shape to better dissipate air above or below the rotor axis can;

- With a rotor cylinder enclosing fixed guide cylinder having stationary vanes, which direct the air flow supplied to them on the rotor blades of the rotor cylinder; and

- with trailing wings, which are directed outside the guide vanes of the fixed guide cylinder on the guide vanes,

- Wherein the collecting wings belong to a swivel cylinder, with which they are pivotable in an optimal catching position, preferably at least partially against the incoming air stream;

- Where the trailing wings staggered in the direction of flow from front to rear and this end from wing to tail wing further spreading laterally, so that the wings catch them metered streams of the incoming air stream and redirect to the guide vanes and

- Wherein preferably the mooring wings experience on both sides of the flowed by the air flow cylinder curvature the same orientations to the air flow or different.

As far as the blades have a helical shape, the helix, e.g. in the area of the center of the rotor axis, mirrored at a mirror plane at 90 ° to the rotor axis, to deflect the wind also (proportionally) in both directions of the axis, up and down in the case of the first vertical embodiment and on both sides after the second horizontal

Embodiment. According to one embodiment, the distance of the tail ends of

Feathering wing calculated using parallels to the direction of flow through the squeegee tips from front to rear smaller, with the exception of the trapping wing. This embodiment variant is intended primarily for operation with a vertical axis. The air flowing in at the side of the wind turbine is also caught by the collecting wings, which are arranged farther back in the direction of flow, and fed to the rotor blades of the rotor cylinder. This makes better use of the wind.

These

End catcher wings provide further capture of laterally flowing air. According to one embodiment, at least one, in a symmetrical embodiment, both of the forwardly drawn tips of a trailing wing overhangs the incident transverse axis, which runs through the rotor axis and is at right angles to the wind direction, while preferably at least two subsequent trailing wings do not do so in total.

In particular, the trapping wings each have forward (i.e., against the direction of the wind) drawn tips, the tip (s) of which project beyond the tip of the respective succeeding wing, possibly also of the second succeeding wing, towards the front.

The trailing fins have in particular wing angles (angle between straight lines 1 and 2), in each case based on a train outer end edge of the mooring to inner end edge (straight line 1) of the mooring wing and inner end edge of the mooring to the rotor axis (straight line 2) of preferably 70 to 90 ° , with asymmetric construction of 60 to 90 ° on one side and 100 to 135 ° on the other side, while the immediately following fishing wings, possibly also the immediately following and then subsequent fishing wings, fishing angle between 115 to 160 °, at asymmetrical construction on one side from 80 to 135 ° (on the catching side) and on the other side from 135 to 180 ° (on the non-catching side). With asymmetrical structure, the wings are longer on average on the catch side of the blades. The catching side is the side of the device where the running direction of the blades corresponds to the wind direction. The non-capture side of the blades is the side of the device where the direction of travel of the blades is counter to the wind direction.

The farther the sails and the tail wings over the largest lateral extent of the guide cylinder in the slipstream to the rear, so are arranged at again decreasing guide cylinder width, the greater the captured air volume. The design should be designed so that the trapped air is distributed as evenly as possible on all flown louvers.

According to a further embodiment of the invention, air baffles are provided which, in the manner of a cap facing away from the wind, open the area above and possibly also below the device (above and possibly also below the device)

Rotor axis) with the cap facing the wind, e.g. by being carried by the windscreen wings.

The second embodiment consists of a device in the manner of a cylindrical wind turbine for harnessing the energy contained in an air stream, which is equipped

with an inner rotor cylinder which has rotor blades acted on by the air and in particular serves for driving a generator which can be driven via the rotor axis, with a fixed guide cylinder enclosing the rotor cylinder, with guide vanes which direct the air flow supplied to them onto the rotor blades of the rotor cylinder,

- Wherein the mooring wings may have the same orientation to the air flow on both sides of the cylinder curvature streamed by the air flow.

This embodiment variant is provided in particular for operation with an approximately horizontally extending axis; It is suitable for installation on a roof ridge. In this case as well, the air flowing in at the side of the wind turbine is caught by the mooring fins located farther back in the direction of flow and fed via the guide fins to the rotor blades of the rotor cylinder.

These slots also serve to grasp an obliquely flowing air stream and supply it to the rotor cylinder. According to a further embodiment of the invention it is provided that air flowing through the slots from the head side air strikes the guide blades and the first third of the blades, wherein the full access of the air to the blades is prevented by means of a rotor cylinder covering the locking plate.

The device according to the invention is realized with two operating forms of wind turbines shown in the drawings.

The first variant 1 of the devices according to the invention is designed and shown in FIGS. 1 to 3 for operation in a vertical axis position. Fig. 1 shows the structure based on air guide cylinders and that the rotor cylinder 2a, guide cylinder 4a and the catch cylinder 5a, which are shown in perspective view of each other in exploded view. Of the cylinders 2a, 4a and 5a, for the sake of clarity, only the blades 2, the guide blades 4 and the fishing wings 5 are shown. All air guide cylinders 2a, 4a and 5a are grouped around the rotor axis 3 of the device. Among the rotor blades 2 a of the rotor cylinder 2 a shown above, the guide fins 4 belonging to the guide cylinder 4 a are shown.

Among the guide vanes 4 associated with the guide vanes 4 is again shown with a larger diameter of the catching cylinder 5 a with fishing wings 5. This

Catching cylinder with its mooring wings 5 has a peculiarity: it is pivotable and aligns in the incoming air flow so that the mooring wings 5 on both sides of the rotor axis 3 adjust to the same position against the air flow.

While the outer edges 6a of all blades 2 on the one hand and the

Outside edges 7 of all vanes 4 on the other sentence each by themselves have the same distances from the rotor axis 3, the outer end edges 8 of the fishing wings 5 all different distances from the rotor axis 3. And that end the fishing wings 5 in the direction of flow from front to rear staggered from Farting wings 5.1 to catcher wings 5.2, etc. further spreading laterally, so that the trailing wings 5 them metered partial air streams 5,12, 5,23, etc. of the incoming air flow capture and redirect to the guide blades 4 and blades 2. The partial flows are described more clearly in FIG. In Fig. 2, the air guide cylinder 2a, 4a and 5a are pushed together. It can be seen that - seen in the direction of flow - behind the fishing wings 5.5, in the lee of the full turbine width B, where the turbine width is again smaller in curvature, in terms of area and extent even more extensive trailing fins 5.6 are. These trailing fins 5.6 are provided on their outer sides with outwardly directed alignment surfaces 9, whereby the trailing wings 5.6 take over the function of a Ausrichtfahne. The closing trapping wings 5, 6 are situated - seen from the inflow side A (FIG. 3) - approximately at an encompassing angle of the guide cylinder of approximately +/- 270 angular degrees. A directional flag 10 may be present or saved.

The trailing edge wings 5, 6 have a greater depth T in the direction of flow A, so that the aligning surfaces 9 do not terminate freely in the direction of flow A, but are integrated into the trailing trapping wings 5, 6. The rear sides 5r are curved inwards in such a way that they promote a negative pressure formation on the rear side 28 of the device 1. An under pressure on the back 28 accelerates the outflow of air and thus at the same time a better air flow.

Fig. 3 shows the variant 1 of the device in plan view. You can see inside the blades 2 of the rotor cylinder 2a. To this group the vanes 4 of the guide cylinder 4a. Again, therefore, group the fishing wings 5 of the catch cylinder 5a.

The outer end edges 8 of the fishing wings 5 load from the inflow side A to the right and left sideways increasingly from front to rear staggered from the fishing wings 5 to fishing wings 5, so that the fishing wings 5 their metered streams 5,12; 5.23; 5.34; 5.45; 5.56 of the incoming air flow and redirect to the guide vanes 4 and the guide vanes 2. The width of the partial streams 5.12 to 5.56 can be changed for optimum utilization of the air flow. Between the fishing wings 5 to fishing wings 5 extending fishing wings 5 fishing wings 5M are provided which do not extend continuously. There are shorter and longer wings 5 and 5M. The continuously extending from fishing wings 5 to fishing wings 5

Fishing wings 5.4; 5.5; 5.6 are partially bent against the direction of flow A to better catch the air.

This division and routing of partial flows applies to both variants of

Device according to the invention.

In all turbines, the shapes of the blades and their arrangement against each other are important. In the wind turbine according to the invention, namely in both variants, therefore special angular positions are preferred. 3a shows an enlarged view of the angular positions of the rotor blades 2. A connecting line 6b between the outer end edges 6a and inner end edges 6 of the rotor blades 2 of the rotor cylinder 2a, to which the incoming air impinges, forms an angle with the connecting line 11 to the rotor axis 3 d equals -20 ° and c2 equals + 30 °.

This means that the inner end edge 6 can be pivoted to an angle 0 to 0 to the center line 11, where it falls on the center line 11. However, the inner end edge 6 can be placed even further to the right with increasing angle c2 to an end edge point 6 ^' on the connecting line 6b pivoted further to the right.

The inner adjacent end edges 6 of the blades 2 are - viewed from the rotor axis 3 - by an angle d between 5 ° to 35 ° apart.

As the enlarged view of FIG. 3b shows, the outer end surfaces 14 of the guide vanes 4 with the imaginary connecting line 15 to the rotor axis 3 angles between e1 equal to -30 ° and e2 equal to -65 °.

The inner air outlet edges 12 of the guide vanes 4 are - viewed from the rotor axis 3 - by an angle f of 5 ° to 35 ° apart.

The inner air outlet edges 16 and the outer air inlet edges 17 of the fishing wings 5 are - as measured by the rotor axis 3 - by an angle h of 5 ° to 35 ° apart. In Fig. 4 to 8, the second variant 20 of the wind turbine is shown according to the invention. The rotor cylinder 2 a with its rotor blades 2 and the guide cylinder 4 a with its guide blades 4 correspond to those of FIGS. 1 to 3

Variation 20 of the wind turbine according to the invention has a roller shape and is designed for operation with a horizontal rotor axis 3. Notably, it is suitable for operation on a roof ridge 21. Different from the first variant according to FIGS. 1 to 3 is the structure of the grouping around the guide cylinder air catcher consisting of the fishing wings 5, Luftleitkämmen 22 and 23, a Luftfangkamm 24 and a collar 26 extending around the center 25 of the cylindrical wind turbine

Trailing wings 5 have in the first blown air flow direction A, where the air first meets the wind turbine 20, wing lengths of increasing length as in the variant according to Fig.1 to 3. The outer end edges 8 of the fishing wings 5 have different distances from the rotor axis. 3 The fishing wings 5 end in the direction of flow from front to rear staggered by fishing wings 5.1 to fishing wings 5.2, 5.3 further spreading laterally.

At the top and bottom, the wings 5K have the same length and end equidistant from the rotor axis 3. The plate-shaped air-combs 22 and 23 are pivotally mounted about the rotor axis 3; they set themselves unloaded or little hit by the air flow in vertical positions. This can be seen from Fig. 5. The return mechanisms can be with spring compensation or

Counterweights work. As the incoming wind increases, they dodge rearwardly, as shown in FIGS. 4 and 7. The largest pivot or wrap angle is seen from the front about +/- 240 degrees. Fig. 7 shows that the air-combs 22 and 23 at

Swing away at a small distance over the wings 5K away. The inflowing air flow strikes the cylinder crown 36 of the wind turbine 20 from below via the roof ridge 21. The air-traction comb 22 thereby supports the introduction of the air into the guide cylinder 4a and the rotor cylinder 2a. At the top, the air flow is intercepted by the air-trapping comb 23 and the upper air-guiding comb 24. During pivoting, the air-trapping comb 23 sweeps under the roof-shaped air-guiding comb 24. It may be that the air does not more or less transverse to the axial position of the device meets this, but obliquely. In order to capture as much air as possible in this case, the collar 26 is provided in the center 25 of the wind turbine 20. As can be seen from Fig. 8, the collar 26 in the cross section 27 has the shape of a drop with the tip 27a to the rotor axis 3. When the air impinges obliquely on the wind turbine 20, then the collar 26 catches the air flowing in front of the collar 26 air part on. The teardrop-shaped cross section 27 delivers the air under flow acceleration to the cylinders 4a and 2a.

The outer collar edge 33 and the outer edges 34 of the Luftleitkämme 22 and 23 are provided equidistant from the rotor axis 3.

If the wind direction of the wind turns and the wind incidence occurs obliquely to Rotorachsrichtung, then catch the collar 26 and the respective end cap 30 the wind with. These end caps 30 are provided with oblique slots 31 in the direction of the running direction of the rotor, which extend between the rotor axis 3 and the outer edge 32 of the turbine.

The air flowing in through the slots 31 from the head side 29 impinges on the vanes 4 and the first third of the blades. As shown in FIG. 6, the full access of air to the blades 2 is prevented by means of a blocking plate 35 partially covering the rotor cylinder 2a. The air entering through the slots 31 of the end cap 30 can thus also be used to drive the rotor cylinder 2a.
