The invention relates to wind energy and can be used to generate electricity. To reduce the weight of the tower and provide resistance to wind gusts in vetroelektroagregate containing tower, wind wheel with a horizontal axis, the multiplier, generator and a swivel base, a tower made of rods, drawn up in the form of two right-angled triangles with a common hypotenuse and sides, and the legs are are parties to the two isosceles triangles with a common base connecting vertices of right angles, the first of which is made horizontal at the top, connects the equal side of the second isosceles triangle mounted bearing assembly to the shaft the propeller and the leading element of the multiplier in the middle base of the isosceles triangle is set first bearing horizontal shaft assembly, a top connecting equal sides horizontal isosceles triangle have a second bearing horizontal shaft assembly, the first end of the horizontal shaft is provided with the driven member multiplier connected flexible coupling with the driving element, the second end of the horizontal shaft connected to a generator, and the horizontal isosceles triangle is on a rotating basis.
DESCRIPTION OF THE INVENTION
The invention relates to wind energy and can be used to generate electricity.
Known generator design with the location of the tower rotating propeller provided with a device installed on the wind [1].
This wind turbine has a traditional type of tower.
Of the known analogues closest to the statement on the essential features of a wind turbine [2], which includes the tower, the two are connected at an angle frame, connected with a support at the joints with the central support unit, propeller, with a horizontal axis mounted on the rack (towers) frames supporting bogie, multipliers, and the rotary base generators, characterized in that the frames are provided with hinges mounted in the central support unit, and have guide devices and synchronizing the device.
The disadvantage of this device is the presence vetrokolesnyh pillars which bear the generating set, which has an increased weight and, therefore, the tower must be designed taking into account the increased load and thus has greater mass.
The invention is aimed at reducing the weight of the tower, providing resistance to wind gusts.
This can be achieved in that the tower is made from rods composed of two right-angled triangles with a common hypotenuse and the catheti, and the catheti are sides of the two isosceles triangles with a common base connecting vertices of right angles, the first of which is made horizontal at the vertex joining equal sides second isosceles triangle mounted bearing assembly with the shaft propeller and a leading member of the multiplier, in the middle base of isosceles triangles installed first bearing horizontal shaft assembly in the top of the connecting equal sides horizontal isosceles triangle has a second bearing horizontal shaft assembly, the first end of the horizontal shaft is provided with a driven member of the multiplier connected to a flexible coupling with the driving element, the second end of the horizontal shaft connected to a generator, and the horizontal isosceles triangle is on a rotating basis.
The achievement of the technical result due to the presence of the rigid tower, the bottom of which is located a shaft to a generator, and the displacement of the pivot axis relative to the base plane of rotation of propeller provide self vetroelektroagregata the wind, which saves on vetroorientiruyuschem device.
Summary of the invention illustrated in the drawing, where is a perspective view schematically vetroelektroagregata.

Vetroelektroagregat includes a tower shaped as a tetrahedron, which is composed of the rod 1, which is a common hypotenuse of two right triangles the catheti of which are pins 2 and 3, which, in turn, are part of the vertical isosceles triangle, pins 4 and 5, which are part of the horizontal isosceles triangle, the rotary base 6, the rods 4, 5, 1 are connected to the second bearing assembly 7 of the horizontal shaft 8, a second end 9 is coupled to a generator 10. The swivel base is provided with a hinge 11 mounted on the base tile 12. Tower 13 is provided with a connecting bridge which is a common base of horizontal and vertical isosceles triangles. In the middle bridge 13 is mounted a first bearing assembly 14, the horizontal shaft 8, a first end of which is provided with a driven member 15, a multiplier which is connected to a flexible coupling 16 to the drive element a multiplier 17, which is fixed to the shaft 18, the propeller 19, the shaft 18 is installed in the bearing assembly 20 . Vetroelektroagregat works as follows, under the influence of the wind flow 21 propeller blades 19 come into rotation while rotating the shaft 18 with the driving member 17. Further, through a flexible link 16 comes to rotate the driven element 15, a horizontal shaft 8 and the generator 10, the electric energy is given in network. When changing the direction of the wind, as a consequence of the fact that the hinge axis 11 is displaced from the plane of rotation of wheels 19, there is an orienting point, under the influence of the wind wheel 19, which is disposed in a plane perpendicular to the direction of wind flow over the tower. |
The advantage of this improvement is vetroelektroagregata weight and size characteristics of the tower, since the rods 1, 2, 3 are calculated only on the weight of the bearing assembly 20, with the wind wheel and the generator 10 located on the base 6 located in the vicinity of the base plate 12.
