The present invention is a support device for a wind turbine assembled of segments with vertical rotation axis.

Multisegment wind turbine with rotors with perpendicular axis of rotation is known from application P.406415, where at least one segment of the turbine is equipped with at least one additional rim or collar releasably attached to the guides of the segment and to the rim of the segment below or to the solid supports of the foundation.

According to the invention, around the column or group of columns comprising segments with wind turbines with a vertical axis of rotation there are masts set together from pipe sections connected by flanges, which are connected with stators of all opposite segments with, favorably, two braces. The masts are equipped with at least one elastic wing, with one edge fixed to the first roller set rotatably on the side of the column, between the flanges of the sections of the pipes. The second, parallel edge of the wing is connected with a tightener, both ends of which connected with rods of pneumatic cylinders, attached inmovably to the mast. Second edge of the wing, with rods of the first pneumatic cylinders at maximum extension, is tangential to the guide of the opposite segment of the column. The wings are favorably installed on every other section of the pipe. The first pneumatic cylinders are connected with a control device coupled with a dynamic pressure sensor and a wind direction sensor.

The first roller, on which the wing is fixed, has a mechanism for folding the wing. Favorably, the mechanism for folding the wing is a spiral spring, with one end fixed to the first roller, and the second end fixed to the fiange of the section of the pipe.

The section of the pipe equipped with the wing has an additional sail made from elastic material, with one edge fixed to the second roller which is fixed to the plates set rotatably on the flange on the end of the pipe. The second, parallel edge of the sail is fixed to the strut, which ends are connected with the second rods of the second pneumatic cylinders. The second pneumatic cylinders are fixed to the plates set rotatably in the supports that are extension of the flanges set on two ends of the section of the pipe. At least one plate has toothing on the part of its periphery, with which a sprocket operates, where said sprocket is an extension of the rod of the third pneumatic cylinder.

Support device increases the air pressure to the turbine rotors and it applies especially to areas where conditions prevent the formation of winds of the appropriate speed. Extended wings increase the air pressure on the blades of the rotors of the wind turbine.

The invention is illustrated in the exemplary embodiment in the drawing, in which Figure 1 shows a view of a column with one mast, Figure 2 is a top view of a column with four masts having supporting devices, Figure 3 is a fragmentary view of the expanded wing, Figure 4 is a simplified, partial top view of the support device, Figure 5 is a fragmentary view of the extended sail, Figure 6 is a top view of the base plate of the sail, Figure 7 is a top view of the set of three columns fitted with four support devices equipped with wings, and Figure 8 shows a fragment of the mast with extended wing and sail.

Around the wind column 1 set from five segments 2 there are four masts 3 placed symmetrically and concreted in the foundations, said masts 3 are set together from pipe 4 sections, connected removably with flanges 5. Pipe 4 sections have length equal to the height of segments 2. The third and the fifth pipe 4 section in every mast 3 is equipped with a wing 6, made from elastic material, such as sailcloth. One edge of said wing 6 is fixed to roller 7 set rotatably in two flanges 5 of pipe 4 section. The second edge of the wing 6, parallel to the axis of the first roller 7, and is fixed to the tightener 8, ends of said tightener 8 are connected with two rods 9 of pneumatic cylinders 10, fixed with clamps 13 to supports 11 and 12 which are the extension of the flanges 5.

Axes of rods 9 are situated perpendicularly to the axis of the mast 3. Surface of the wing 6, as shown on Figure 4, is oriented so that it is positioned in one plane with surface of the guide 14 of the segment 2, wherein with maximum extension of rods 9 the second edge of the wing 6 is favorably tangential to the edge of guide 14. Beside that the first roller 7 has the first mechanism 15 for folding of the wing 6 in a form of spiral spring, one end of said spring being attached to the first roller 7, and the other end to the flange 5. Pipe 4 section not equipped with the wing (16) are connected with stators of each opposite segment 2 with two struts 16.

Alternatively, each pipe 4 section equipped with the wing 6 additionally is equipped with a sail 17 made from elastic material, attached with one edge to the second roller 18 fixed rotatablly to plates 19 and 20. Said roller 18 is also fixed rotatably in supports 21, which are the extensions of flanges 5. The second, parallel edge of the sail 17 is fixed to the strut 22, parallel to the axis of the pipe 4, ends of said strut 22 are connected to the second rods 23 of the second pneumatic cylinders 24 fixed to plates 19 and 20. Second roller 18 has the second mechanism 25 for folding the sail 17 in a form of the spiral spring, one end of said spring being attached to second roller 18, and the second end to the plate 19.

Plate 19 has toothing on the part of its periphery, with which a sprocket 26 operates, where said sprocket 26 is an extension of the rod of the third pneumatic cylinder 27.

If the columns of the turbine 1 are set in a group of, for example, three columns 1 on the set of an equilateral triangle, masts 3 with wings 6 are set on the outside of the group of columns 1 in such way, that the extended wings 6 does not screen the guides 14 from the direction of the wind of other columns 1. Favorably, more than two masts 3 are installed next to each column 1.

The support device works as follows. When the wind speed is small, and it's direction is perpendicular to the plane of the wing 6 or retrorse by ± 45° - first rods 9 of the first pneumatic cylinders 10 on one of the masts 3 are extended, and the vertical edge of the wings 6 in next to segments 2 of the column 1. When the wind changes its direction, said rods 9, on the signal from an air movement sensor installed on the column 1, fold the wings 6 on this mast 3, and at the same time, first rods 9 extend wings 6 on the other mast 3, said wings 6 are at the right angles to the wind and direct additional air coming from the other side to the appropriate guides 14 of the wind turbine.

In the case of increase of wind speed above the admissible level, on the signal from the dynamic pressure sensor installed on the column 1, the control system, not shown, causes the withdrawal of the rods 9 and folding of wings 6 until the reduction in the wind speed.

In the case of a wind turbine location is in an unfavorably shaped area, the masts 3 are equipped with additional sails 17 that increase air pressure to the blades of the rotors of the segments. Inclination of the sail 17 at an obtuse angle relative to the wing 6 directs part of the air flowing outside from the wing 6.
