Description

The invention relates to a device for wind-generated rotational movement of an impeller in which the wing surfaces are designed as advertising surfaces based on flags or banners elongated in the direction of a rotation axis, in particular for vertical mast construction and large wind loads.

Such Werbewindrotoren are usually equipped with a three-bladed so-called Savonius rotor, which is flanged on a mast rotatable and consists of a plastic composite material for ease of movement and low weight load. Such advertising wind rotors are for mobile applications (eg convertible or on vehicles carryable advertising), for example DE 20 2015 103 259 U1 and DE 20 2015 005 749 U1 known. Two-winged wind rotors are in the DE 88 04 674 U1 and in the DE 44 26 645 A1 The latter describes a tapered roller bearing as a speed-limiting braking device.

All of the aforementioned technical solutions of the advertising wind rotors has the disadvantage that they are either close to the ground and kept small or are not suitable for large wind loads, so not for large heights and long rotor blades. A further disadvantage is that no consideration of different wind speeds is provided in any of the facilities.

The invention has for its object to find a novel way to wind-generated rotary motion of an impeller in which the wing surfaces are designed as advertising surfaces based on flags or banners elongated in the direction of a rotation axis, which is designed for large wind loads and a simple , modular and lightweight construction allowed. As an extended task for wind stabilization, an adaptation of the rotational speed to different wind speeds should be possible.

According to the invention, the object is formed in an apparatus for wind-generated rotational movement of an impeller in the wing surfaces as advertising surfaces based on flags or banners elongated in the direction of a rotation axis containing an impeller with multiple wings, which is made of a fiber composite plastic, and a tubular Carrier mast, on which the impeller is rotatably mounted about the axis of rotation parallel to a mast axis, achieved in that the impeller has inside a rotor column which pierces the impeller to end plates along a rotation axis and with a mounted at a lower end of the rotor column rotor column flange, which is rigidly fixed to a lower end plate of the impeller, is connected to a rotary bearing unit of the support mast, wherein introduced into peripheral holes of the Rotorsäulenflansches pins or screws for non-positive connection of the impeller with a Fla nsch the rotary bearing unit of the support mast are provided, and that the rotary bearing unit between carrier mast and impeller is designed both as a rotary bearing and as a braking device for the impeller, which is flanged between each Rotorsäulenflansch and a mast flange of the support mast.

Advantageously, the rotor column is formed as a metallic tube with cohesively mounted Rotorsäulenflansch. However, it may also be expediently designed as a fiber composite plastic pipe with cohesively mounted Rotorsäulenflansch.

The rotary bearing unit has for the rotary bearing of the impeller expedient along a pivot bearing shaft at least a pair of ball bearings and at least one angular contact bearing. In a design that is particularly stabilized for large wind loads, it can also have at least one pair of ball rolling bearings and two skew bearings arranged outside the pair of ball rolling bearings along a generator shaft (31).

Preferably, the rotary bearing unit is formed by a generator, which already brings along the necessary for the rotary bearing rolling bearings along the rotary bearing shaft of the generator and is detachably frictionally connected to a shaft flange and a housing flange between the rotor column flange of the impeller and mast flange of the support mast.

In this case, the generator can advantageously be fastened with its housing flange on the mast flange of the support mast, wherein the generator is completely embedded with its housing in the support mast, and the shaft flange is connected to the Rotorsäulenflansch of the impeller.

In another preferred variant, the generator is fastened by its shaft flange to the mast flange of the support mast and the housing flange is connected to the rotor column flange of the impeller.

When the housing flange is connected to the rotor column flange of the impeller, it proves to be particularly advantageous that the generator is embedded with its housing in a cavity below the lower end plate of the impeller.

To improve the stability of the shaft flange of the generator may preferably have gusset plates or alternatively have a molded onto the rotary bearing shaft shaft flange.

In a preferred embodiment, an additional metallic base plate is present in a cross-sectional plane of the lower end plate of the impeller intimately woven with the fiber composite plastic of the lower end surface of the impeller by lamination or casting, with peripheral bores of the base plate in at least partial registration with the bores of the rotor column flange are provided for pins or screws for connecting the base plate through the Rotorsäulenflansch with a flange of the rotary bearing unit or the generator on.

Preferably, the Rotorsäulenflansch in addition to the matching with the base plate holes for non-positive flange connection further holes for rivets or screws for releasably securing a flange of the rotary bearing unit or the generator.

It also proves to be expedient for the stability of the impeller that an additional metal head plate with a passage opening for centering the rotor column within an upper end plate ( 27 ) of the impeller ( 21 ) is available.

In this case, the metallic top plate is advantageously intimately woven into the upper end plate of the impeller by means of lamination or pouring with the material of the upper end plate.

• - Verschrauben der Drehlagereinheit am Mastflansch des Trägermastes über einen mittels Nutmutter am Drehlagerschaft der Drehlagereinheit zentriert angebrachten Schaftflansch und zusätzliches Sichern durch Nutmutterscheibe.

The object is further achieved in a method for producing a Werbewindanlage with wind-generated rotational movement of an impeller for large wind loads by the following sequence of steps:

• - Insertion of end plates as closures of the end cross-sectional surfaces of the hollow body and cohesive bonding;
• Inserting a tubular rotor column with a lower integrally connected rotor pillar flange and fastening the rotor pillar flange to the end plate, being anchored in the rotor pillar flange in bores correspondingly aligned with bores of the pivot bearing unit, or used for attachment when the pins or screws ( 29) are already predetermined from the end plate;
• - Completely incorporating the rotor column flange in the lower end plate of the impeller;
• - Frictionally securing the pivot bearing unit of the support mast to the lower end plate of the impeller on pins or screws, which are inserted into matching holes of the rotor column flange, and
• - Screwing the pivot bearing unit to the mast flange of the support mast via a centered by means of nut on the pivot bearing shaft of the pivot bearing unit mounted shaft flange and additional securing through Nutmutterscheibe.

• - das Einsetzen und innige stoffschlüssige Einarbeiten einer metallischen Basisplatte (26) in die untere Endplatte (24) des Flügelrades (21) sowie
• - das kraftschlüssige Befestigen des Rotorsäulenflansches (23) mit der Basisplatte (26) des Flügelrades (21) mittels in übereinstimmend angeordneten Bohrungen (28) von Rotorsäulenflansch (23) und Basisplatte (26) in die Basisplatte (26) stoffschlüssig eingesetzten Stiften oder Schrauben (29) .

To increase the stability of the rotor unit against high wind loads, the following steps are additionally carried out before inserting a tubular rotor column and screwing its rotor column flange to the lower end plate of the impeller:

• - The insertion and intimate cohesive incorporation of a metallic base plate (26) in the lower end plate (24) of the impeller (21) and
• - the non-positive fastening of the rotor column flange ( 23 ) with the base plate ( 26 ) of the impeller ( 21 ) by means of matching holes ( 28 ) of rotor column flange ( 23 ) and base plate ( 26 ) in the base plate ( 26 ) cohesively inserted pins or screws ( 29 ).

Furthermore, advantageously, after the base plate has been worked into the lower end plate of the impeller, an additional metallic top plate can be screwed into the upper end plate of the impeller or integrally incorporated. It proves to be useful to glue at least the base plate and advantageously also the top plate, pour or einzulaminieren.

The invention is based on the basic idea that advertising winders can replace as well as permanent installation well-known advertising flags or banners, which can be realized by the wind-generated rotary motion of a preferably dreiflügeligen rotor impression of a waving banner with significantly increased life. The plastic composite construction of the impeller, preferably as dreiflügliger Savonius rotor made of a fiber composite plastic - FVK (eg: fiberglass - glass fiber composite plastic or CFRP - carbon fiber composite plastic), but is no longer unbreakable against large wind load in large advertising space and then has to be limited in the rotational speed.

A compromise according to the invention is that the impeller has a rotor column in the interior between two star-shaped upper and lower end plates closing off the three-winged FRP hollow body along the axis of rotation and stiffening via a rotor column flange, possibly with gusset plates, rigidly connected to the lower end plate of the impeller and suitably flanged to a pivot bearing unit of the support post construction by means of a releasable connection to enable interchangeability of individual components. To adapt to different wind loads and wind speeds, the assembly rotor shaft - Rotorsäulenflansch, preferably reinforced by a base plate, which is preferably laminated or cast in the FVK impeller, coupled with an additional braking device, which is integrated in the rotary bearing unit and at the same time as a generator unit can be trained. As a result, a power generation and the possibility of an energy storage operation are opened to realize lighting devices or a rotor rotary drive for wind surges in addition.

In a preferred embodiment, the impeller with rotor column and the relatively large Rotorsäulenflansch is designed such that in the Rotorsäulenflansch holes are provided for fastening bolts through which by screwing a rigid connection between the impeller and a support flange vertically flanged to a vertical axis of rotation rotatable rotary bearing unit or the impeller of the generator unit used as a braking device is produced. Advantageously, the Rotorsäulenflansch is supplemented by a Flügelradstützende base plate, which is integrally incorporated into the lower end plate of the impeller and with at least partially coincident with the Rotorsäulenflansch holes for inserted pins or screws for non-positive connection of the base plate through the Rotorsäulenflansch through with a flange, shaft - or housing flange) of the rotary bearing unit is provided.

In addition, for further lateral load stabilization of the impeller other than the base plate in the lower end plate of the impeller also a top plate in the upper end plate of the impeller can be used if the rotor column the impeller pierces completely (until through the upper end plate). The top plate is rigidly connected, preferably bolted, glued or laminated, in a manner similar to the base plate with the star-shaped lower end plate, to the upper end plate of the impeller and provided with a center opening for centering the upper end plate of the impeller on the rotor column.

With the invention, a novel Werbewindanlage for wind-generated rotary motion of an impeller in which the wing surfaces are designed as advertising surfaces based on flags or banners elongated in the direction of a rotation axis, realized, which is designed for large wind loads and a simple, modular and lightweight construction allowed. The wind stabilization can be improved by changing the load of the rotational speed of a generator used as a braking device to different wind speeds.

An inventive device for wind-generated rotary motion of an impeller for promotional purposes (short: advertising wind turbine) includes in its basic structure - as in 1 shown schematically - a support mast 1 , in various ways the support by means of a mast support 4 stationary on the ground or on a mobile support ensures a rotor unit 2 containing the impeller 21 , which is a preferred, but oBdA three-bladed Savonius rotor made of a fiber composite plastic (FRP), one in the impeller 21 incorporated in the FVK rotor column 22 , which is formed in this example as a metal tube and a metallic Rotorsäulenflansch 23 having, with the rotor column 22 rigid and preferably cohesively connected and is designed such that a wind load stable detachable connection of the impeller 21 with the carrier mast 1 via a rotary bearing unit 3 manufacture.

The rotary bearing unit 3 includes both rotary and at least one vertical support bearing for the rotor unit 2 and can be either in the carrier mast 1 or in the impeller 21 be arranged sunk or between Rotorsäulenflansch 23 and a mast flange 12 openly visible as in 1 shown to be used. The rotary bearing unit is preferred 3 by a between the Rotorsäulenflansch and the mast flange 12 bolted brake unit is provided, wherein the brake unit according to a preferred embodiment of the invention in the form of a powerful generator 35 is trained. For particularly high wind load strength of Werbewindanlage the generator 35 as a complete rotary bearing unit 3 in addition to the conventional ball bearings 32 at least one additional angular contact bearing 33 exhibit.

In 2 is the rotor unit 2 shown in two different sectional views. The first cross section a) runs along the in 1 marked plane AA through the lower end plate 24 the impeller 21 and the second section b) in the plane BB through the upper end plate 25 the impeller 21 ,

In the sectional view AA, a metallic plate is drawn within the lower end plate, for example, from the Rotorsäulenflansch 23 can be formed, causing the rotor column 23 rigid in the lower end plate 24 the impeller 21 embedded and intimately interwoven. The rotor column 22 , as in 3 is preferably formed as a stainless steel tube or light metal tube, which provides additional rigidity with the rotor column flange 23 through gusset plates (in 3 only optional, dashed, drawn) can receive. At the top of the impeller 21 becomes the upper end plate 25 from the rotor column 22 pierced, causing the (hollow) impeller 21 around the axis of rotation D center and the impeller reaches a higher resistance to high wind load. Additionally, at the upper end plate 25 a metallic head plate 27 , as in the partial view b of 2 drawn on or be introduced, which has an opening for the passage of the rotor column 22 providing to the impeller 21 around the axis of rotation D centered variably and its transverse stiffness (against transverse wind load) can be further increased.

The rotor column flange 23 also has holes 28 on, in the pins or screws 29 rigid or twist-proof and directed downwards to connect to the pivot bearing unit 3 on the carrier mast 1 manufacture. Preferably, the rotor column flange 23 in the lower end plate 24 additionally from a base plate 26 as seen in the partial view of 2 is shown to be reinforced, with the base plate 26 before inserting the rotor column 22 in the lower end plate 24 used and woven or laminated.

The base plate 26 has the same holes 28 like the rotor column flange 23 on and in the same way with pins or screws 29 stocked, with all holes 28 of the rotor column flange 23 stay clear when in the appropriate hole 28 the base plate 26 Pins or screws 29 are used. In this case, the rotor column flange 23 not necessarily in the end plate 26 can be woven, but also only with the screws 29 the base plate 26 against the overlying layer (s) of the end plate 24 be screwed. An additional further lamination or pouring of the rotor column flange 23 but is possible and useful. If the rotor column flange 23 stabilized with gusset plates are in the base plate 26 in addition to the middle opening for the rotor column 22 Radial slots (three examples here) provided that allow the existing gusset plates partially penetrate. Furthermore, it makes sense that the base plate 26 Has bulges, which provides a better twist-proof embedding of the base plate 26 in the material of the end plate 24 to guarantee. The same applies to the top plate described above 27 in the upper end plate 25 the impeller 21 ,

4 shows the in 1 marked detail C, which further coupling the rotor unit 2 at least containing the impeller 21 with the two end plates 24 and 25 , the rotor column 22 with the rotor column flange 23 and - in the example chosen according to 4 - with the additional base plate 26 , showing in detail. In the drawn version of 4 are all holes 28 the base plate 26 with screws 29 (Stud) equipped and welded, for example. The screws 29 pierce the holes 28 of the rotor column flange 23 and matching holes of the shaft flange 351 of the generator 35 and are secured by nuts or rivets for frictional connection between impeller 21 (on the base plate 26 attacking) and rotary bearing shaft 31 used.

The generator 35 is in accordance with the design 4 provided with a slim installation housing in the interior of the support mast 1 dips in and with the housing flange 352 with the flange of the carrier mast 1 is screwed. The generator 35 In this example (without limitation of the general public) has the following peculiarities, which can also be applied to all subsequent examples. The shaft flange 351 is in this case directly on the rotary bearing shaft 31 of the generator 35 molded, so that a high rigidity and a short height is achieved. The rotary bearing shaft 31 is in addition to the usual pair of ball bearings 32 with a top mounted angular contact bearing 33 stored and thereby forms a storage unit 3 , which has a high transverse rigidity of the pivot bearing shaft 31 as well as the it over the shank flange 351 non-positively coupled rotor unit 2 with the impeller 21 guaranteed.

Another embodiment of the coupling between the carrier mast 1 and rotor unit 2 is in 5 shown. Again, the in 1 marked section C shown enlarged, which in the same way the impeller 21 with the internal rotor column 22 , Rotor column flange 23 and base plate 26 having, wherein the base plate 26 as in the previous example in with holes 28 attached pins or screws 29 is provided by appropriate holes 28 of the rotor column flange 23 and the housing flange located above here 352 of the generator 35 a frictional connection between impeller 21 and generator 35 produce. As in the below sectional view of 5 in addition, is the generator 35 in this example, an exposed generator and pivot bearing unit 3 , in this case, on the rotary bearing shaft 31 one via a tongue and groove connection 354 coupled shaft flange 351 has, by means of a grooved nut 355 is secured, and by means of gusset plates 353 at the rotary bearing shaft 31 of the generator 35 supported to achieve the required transverse rigidity. At the rotary bearing shaft 31 is also next to the ball bearings of the generator 35 still an additional skewed roller bearing 33 arranged in the generator housing, whereby the rotary bearing unit 3 in the generator 35 is fully integrated. The generator 35 but also with two angular roller bearings 33 and 34 be equipped if this is necessary for very large wind loads.

The generator 35 is here as a rotary bearing unit 3 and points to the pivot bearing shaft 31 one via a tongue and groove connection 354 coupled shaft flange 351 on, by means of a grooved nut 355 is secured and by means of gusset plates 353 at the rotary bearing shaft 31 supported to achieve the required transverse rigidity. The shaft flange 351 is, as can be seen in section C, with screws 29 at the mast flange 12 of the carrier mast 1 firmly screwed.

As 6 is the third embodiment of the coupling of carrier mast 1 and rotor unit 2 the advertising wind turbine similar for example according to 5 designed with the difference in education of the shank flange 351 according to the representation of 4 , wherein the shaft flange 351 directly to the rotary bearing shaft 31 of the generator 35 is formed. Like the lower section of the generator 35 shows is the pivot bearing unit 3 here by a case resistant generator 35 formed, wherein the housing flange 352 in section C on the mast flange 12 of the carrier mast 1 is screwed seated. Over the mast axis 11 the generator is sitting 35 with one, as in 4 described, at Drehlagerschaft 31 molded shank flange 351 as the upper end of the carrier mast 1 and represents the impeller to be coupled 21 a flange surface ready. The generator 35 is again as a rotary bearing unit 3 with a pair of ball bearings 32 and two oppositely positioned angular contact bearings 33 and 34 equipped and at the same time provides a brake unit for the top-mounted impeller 21 where the generator 35 has a corresponding generator load control, the in 6 only symbolically as an electronic speed controller 356 is shown. The load control is a wind speed-dependent control of the braking effect of the generator 35 suitable, thus reducing the wind load susceptibility of conventional wind turbines and contributes to the improved wind protection of the advertising wind turbine according to the invention.

About the programming of the speed controller 356 by entering a preselected power decrease from the generator 35 is achieved that the generator 35 with the rotary bearing shaft 31 maintains a constant rotational speed, which at 40 to max. 60 rpm. That means when on the speed controller 356 If a higher power decrease is input, the resistance or torque in the generator increases 35 on the magnet or coil elements and the generator 35 can with the rotary bearing shaft 31 so do not turn faster. The force, the torque, is at the power take-off at the generator 35 higher than the pivot bearing shaft 31 of the generator 35 this technically and physically from the impeller 21 can transfer and thus the pivot bearing shaft 31 of the generator 35 decelerated. This in turn means that, for example, at 4 m / s up to the maximum permissible wind speed, a power curve can be programmed so that the advertising wind turbine is braked increasingly magnetically at higher speeds and thus always performs a relatively constant rotational motion, for example in the range of 40 - 60 U / min. The workspace of the generator 35 is for example between 0 and 300 rpm, by programming the power and brake curve, the working range is almost constant and just below it in low wind. This version of the generator 35 as a controllable brake unit is used and applied in the same way for all previous examples and the subsequent embodiment, when the advertising wind turbine according to the invention is provided for correspondingly high wind loads.

The control scheme for the speed controller 356 is schematically in Table 1 for the above-mentioned work area of the generator 35 represented by the rotational speeds of the impeller 21 associated with the empirically determined for a Savonius rotor associated wind speeds.

In 7 is the positioning and screwing of the generator 35 as a rotary bearing and brake unit in principle as well as in the execution according to 5 intended. The difference is in the introduction of the generator 53 into a dome-like cavity of the lower end plate 24 the impeller 21 , which is formed particularly massive and bell-shaped bulging, to above and below the base plate 26 sufficient material (FRP) as a viable impeller lock and for intimate lamination or gluing the base plate 26 to the rotor column flange 23 for the subsequent non-positive coupling to the shaft flange 351 of the generator 35 also having with its shank flange 351 and to find essential parts of its housing in the dome-shaped cavity. The non-positive connection with the mast flange 12 of the carrier mast 1 is the same as in the previous example 5 educated. The generator 35 Here is again a rotary bearing unit 3 on the pivot bearing 31 one via a tongue and groove connection 354 coupled shaft flange 351 has, by means of a grooved nut 355 is secured, and by means of gusset plates 353 at the rotary bearing shaft 31 supported to achieve the required transverse rigidity. The rotary bearing unit 3 is through the next to the ball bearings 32 of the generator 35 existing two additional mirror symmetric to the ball bearings 32 along the pivot bearing shaft 31 arranged .Anschrägwälzlager 33 and 34 formed. The shaft flange 351 is, as can be seen in section C, with screws 29 at the mast flange 12 of the carrier mast 1 firmly screwed and thus freely accessible and easy to install.

For the invention, the production of the impeller 21 until the provision of a flange-like coupling point of particular importance for the high stability for high wind loads. The procedure consists of the following steps:

1. 1. The "star-shaped" upper and lower end plates 24 and 25 of the impeller 21 are inserted as lamination, which is inserted and laminated in the hollow body of the impeller 21 made of fiber composite plastic, glued or potted.
2. 2. Thereafter, the rotor column 22 are glued with a large Rotorsäulenflansch 23 or additionally a base plate 26 on the lower recessed end plate 24 of the impeller and laminated or potted. Depending on whether an additional base plate 26 is glued or not, either the base plate 26 or the rotor pillar flange 23 has an appropriate pattern of holes in the pins, to the flanges of the pivot bearing unit 3, which is at best designed as a generator unit 35 or screws 29 are used rigid.
3. 3. If the base plate 26 has been inserted into the end plate 24, there is the advantage of easier assembly of the rotor column 22, which is then attached to the pins or screws (studs) of the base plate 26 with its Rotorsäulenflansch 23 and screwed. Otherwise, the rotor post flange 23 provided with pins or screws 29 is glued into the lower end plate 24 or otherwise intimately woven with the end plate 24.
4. 4. Thereafter, there is a possibility or necessity of adhering the rotor pillar flange 23 to the lower end plate 24 of the impeller 21, depending on whether a base plate 26 constituting the screw anchor has been glued or the rotor pillar flange 23 is provided therefor. This increases stability and creates an outer finish.
5. 5. Subsequently, the impeller 21 is closed by gluing the upper star-shaped end plate 25 above and laminated with an optional metallic top plate or screwed additionally, thereby centering and lateral fixation of the impeller 21 in the upper Area is ensured.
6. 6. Finally, the screwing of the generator 35 as a brake and rotational position unit 3 to the pins or screws 29 lower end plate 24, which are laminated by the base plate 26 or the Rotorsäulenflansch 23 in the end plate 24 is provided.
7. 7. Finally, the assembly of the so far prepared rotor unit 2 on the mast flange 12 of the support mast 1 with one of the generator flanges, shaft flange 351 or housing flange 352, preferably with a centering groove nut, which is additionally secured by Nutmutterscheiben.
