Description

The invention relates to wind energy and is an improvement with the position of minimalism of segment-type wind generators.

Known segmented wind generators are described, for example, in cl. RF No. 2267028, op 27.12.2005, bull. No. 36, production unit No. 20041 898/06 dated July 08, 2004 - “a segmented wind generator”;

P. RF №230012, op.27.05.2007, bull. No. 15, building No. 2005137101/06 dated November 29, 2005 - “Wind Generator”;

P. RF №2383774, op.10.03.2010, bull. No. 7, office No. 2008128748/06 dated 07/14/2008 - “Wind power generator”.

The disadvantage of these segmented wind power generators is their multi-rotor, which leads to complication of the design.

The closest in technical essence is the wind generator described in paragraph. RF №2515570, publ. 05/10/2014, bull. No. 13, part No. 2011109281/06 of 03/11/2011 - “Segment-style wind power generator”. It contains a pipe stand, a segmented rotor and a stator, a rotating base, although it is also multi-rotor, but its performance is somewhat increased due to the use of counterweight rotors.

The disadvantage of this wind generator is the design complexity caused by the presence of a large number of elements.

The invention is aimed at simplifying the design as much as possible, increasing reliability.

This is achieved by the fact that in a segmented wind generator containing a pipe stand, a segmented stator and a segmented rotor in the form of a wind wheel with blades, the rotating base, according to the invention, the rotating base is made in the form of bodies of revolution, the lower part of which is cylindrical and the upper part is in the form of a truncated cone located large base down in the upper part of the cone made a radial and axial threaded hole, and in the middle part of the mounting holes for the vertical stator brackets connected by struts with a tail beam fixed in an axial threaded hole, while the tail surface is made in the form of a flexible shell covering the struts and tail beam.

The invention is illustrated in the drawing, which shows a side view of a wind generator, partially in section.

A segmented wind generator contains a pipe holder 1, a segmented stator 2, a rotor element 3 of a segmented rotor — a wind wheel with blades, a hub 4, a shaft 5. The base rotating in the wind is made in the form of a body of revolution, the lower part 6 of which is cylindrical, and the upper 7 part is made in in the form of a truncated cone, a large base down, which simultaneously serves as a sliding bearing 8. Two holes are made in the upper part of the cone: radial through 9 and axial threaded 10. In the axial hole 10, the tail beam fastening screw 11 is fixed 12. In the radial through hole 9, the wind wheel shaft is fixed using an asymmetric washer 13 and nut 14. In the middle part of the truncated cone there is an opening 15, which serves for fastening the bolt, tightening the struts 16, the base and vertical brackets 17 of the stator 2. The brackets 17 have additional struts 18 for mounting the stator. The tail surface is made in the form of a flexible shell covering the struts 16 and the tail beam 12, and fixed at the corners on the struts and in the middle on the tail beam. The flexible sheath can be made of a reinforced film or of any flexible material.

The operation of the device is as follows. When the wind flow runs from left to right, the wind wheel with blades fixed in the hub 4 and rotor elements 3 at the ends of the blades comes into rotation. In this case, e is induced in stator 2. d.s When changing the direction of the wind, the flow acts on the shell 19, stretched on the beam 12 and struts 16. Through the fastening elements, the moment is transmitted to the rotating base (parts 6 and 7), which leads to the fact that the base rotates relative to the pipe. Together with it, the brackets 17 with the segment stator 2 and the wind wheel with rotor elements 3 are rotated, that is, the wind generator continues to function.

The technical and economic advantage of the claimed invention is the relative simplicity of the design, since although the execution of a rotating base requires turning operations, the upper conical part ensures the stator mounting brackets at the required angle, while maintaining alignment with the rotor elements.
