WIND-ENGINE

Abstract: A wind-engine of the type consisting of several wind devices rotatably mounted at several independent stages, which comprises the combination of vertical props (1) disposed within a circle (4) ; at each stage (2), crossbeams (5) connected, on one hand, to the vertical props (1) and meeting, on the other hand, at the center of the said circle (4) ; a vertical axis (7) situated at the center of the said circle (4) and, at each stage, a wind device rotatably mounted about the said vertical axis.

Description: This invention relates to a wind-engine, more particulary, an engine of the type comprising several wind devices disposed independently and rotatably to each other at several stages. For such a wind-engine has already been deposited the Swiss patent applicaTion no 2411/86. Such known structure has several stages each of which is provided with a suitable number of wind devices capable of being individually rotated in the wind. This is advantageous in that the wind layers situated at different levels may be used although the phases of air input are set off. The object of the present invention is such an engine which is stable even at high levels and at high wind speeds. Stable wind engines with two wind mills mounted on one and the same stage are known from U.S.-A-1.498.978 and FR-A-1.074.780. These patents however do not disclose structures which are apt at supporting an engine having several wind mills disposed at several stages. In order to obtain the above said object of the invention, the present invention relates to a wind engine of the type consisting of vertical props disposed within a circle ; a vertical axis situated at the center of said circle and several wind devices rotatably mounted around said axis at several independent stages, characterised in that it comprises at each of said stages, crossbeams connected, on one hand, to the vertical props and meeting, on the other hand, at the center of said circle; said crossbeams supporting at each stage one of said wind devices. In an alternate embodiment, at least one substantially horizontal element provided with several wind devices is rotatably mounted about the said axis, the said element being supported by the crossbeams. The features of this invention will be more clearly apparent from the following description of some preferred embodiments given only by way of example without any limitation, reference being made to the enclosed drawings in which : Figure 1 shows a wind-engine according to the invention ; Figure 2 shows a section taken on the lines II-II of Figure 1 ; Figure 3 shows an alternate embodiment ; Figure 4 shows a section taken on the lines IV-IV of Figure 3 ; Figure 5 shows another embodiment of a detail of Figure 4 ; Figure 6 shows another embodiment of the engine according to the invention ; Figure 7 shows another embodiment of an engine according to the invention ; Figure 8 shows a section taken on the line VIII-VIII of Figure 7. As shown in Figures 1 and 2, the wind-engine according to the invention comprises substantially a number of vertical props 1 supporting several rotating stages 2 each of which is provided with several wind devices 3. The vertical props 1 are equally spaced along a circle 4. Of course, the number of vertical props 1 will depend namely on the height of the wind-engine. Each stage 2 comprises crossbeams 5 connected, on one hand, to the vertical props 1 and meeting, on the other hand, within the center 6 of the circle 4. At the center 6 of the circle 4 is rotatably mounted, but without any possibility of axial mouvement, a vertical axis 7 on which are mounted several horizontal bearing elements which are themselves bearing the wind devices 3 in any suitable manner. The crossbeams 5 are meeting together at the center 6 of the circle 4, either as shown in the left portion of Figure 2, or as shown in the right portion of Figure 2, thereby forming an opening 9 for an axis 7, on one hand, and for the electric conductors, etc., on the other hand. The bearing elements 8 are lying on the crossbeams 5 through a structure 10. Said bearing elements 8 are provided with a driving device (not shown in the drawings) allowing to orientate the wind devices in the wind. It is apparent that every wind device 3 or every group of wind devices 3 is connected to a generator. In the alternate embodiment of Figure 3, the axis 7 is continuous. In this embodiment, the axis 7 has preferably longitudinal grooves in which conductors or the like may housed. Collecting rings 11 diagrammatically represented in Figure 3 may be mounted about the axis 7. Figure 4 shows that the crossbeams 5 are secured to or respectively supported by the axis 7. Figure 5 shows an embodiment in which the axis 7 consists of several tubes 12 interconnected through rings 13. Figure 6 shows still another embodiment in which the bearing elements 8 are divided into two superimposed portions 14 and 15 connected with a rotating central portion about the axis 7. Finally, Figure 7 shows an embodiment comprising, at each stage, only one wind device 3 rotatably mounted on the upper end of the vertical axis 7. In this embodiment, driving means (not shown in the drawings), e.g. an electric motor or the like, are provided between the wind device 3 proper and the corresponding vertical axis, it being thereby possible to orientate every wind device in the wind in the same manner as for the other embodiments. It is apparent that the present invention is not at all limited to the examples described and represented in the enclosed drawings, but that, on the contrary, it includes the wind-engines in any shapes and sizes.

Claims: A wind-engine of the type consisting of vertical props (1) disposed within a circle (4); a vertical axis (7) situated at the center of said circle (4) and several wind devices rotatably mounted around said axis (7) at several independent stages, characterised in that it comprises at each of said stages (2), crossbeams (5) connected, on one hand, to the vertical props (1) and meeting, on the other hand, at the center of said circle (4), said crossbeams (5) supporting at each stage one of said wind devices. A wind-engine according to claim 1, characterised in that it comprises at least one substantially horzontal element (8) provided with several wind devices (3), said element (8) being supported by the said crossbeams (5).
