Description

vertical axis wind turbine for the production of electricity

Description:

The constant operation with any wind direction even with turbulence, the total absence of noise and vibrations, the safety for passing birds, the greater constructive simplicity, the lower number of moving parts, than compared to traditional wind machines with a horizontal axis, it makes a vertical axis wind turbine to be inserted in urban furniture, in public lighting, above houses, in the garden and in any other place where there is wind. Steel, aluminum, plastic (with special shapes), and glass resin are the materials that can be used for the construction of the rotor. What I will consider later is steel. By means of a laser I cut 2 sheet metal discs with a thickness of 3 mm. with a diameter of 1.5 meters; n ° 2 sheet metal discs with a thickness of 1,5 mm. with a diameter of 1.0 mt. with a hole in the center with a diameter of 0.4 meters. (see table n ° l, drawing A / l); n ° 6 rectangular sheets with a thickness of 1.5 mm. with the dimensions 1,5 mt. x 1.047 mt .. In discs with a diameter of 1.5 mt. using the laser I make holes, see (table n ° 1, drawing A / 2) and I make traces, see (table n ° 2, drawing A / 4); I take three of the six rectangular sheets and make a trace, see (table n ° 3, drawing A / 5), using a calender with a curvature of 1.0 in diameter, I pass the three sheets, taking care that the trace remains external, thus obtaining a third of a cylinder that I will cut along the track, I will not cut it first due to technical calendering problems. I take one of the two discs with a diameter of 1.5 meters. and I arrange it on a surface by placing them on the three curved sheets, see (table n ° 2, drawing A / 3), on top of the three sheets I rest the previously cut disc with a diameter of 1.0 m. with hole 0.4 mt. , see (table n ° 3, drawing A / 6), taking great care with the leads and levels, I move on to welding. As you can see from the drawing you see (table n ° 2, drawing A / 3) the direction of rotation of this turbine is counterclockwise. In the same way, by changing the trace in the remaining three rectangular sheets see (table No. 4, drawing B / l), I create another turbine with the direction of rotation clockwise, see (table No. 4, drawing B / 2). I obtained two wind turbines, one with a counterclockwise rotation direction and the other with a clockwise rotation direction, holding one still, overturn the other and insert it under, making the 10 mm holes coincide. made previously and staggering the sails by 60 ° with respect to each other, thus obtaining a single turbine with a vertical axis, with an empty space in the middle both from the top and from the bottom where I insert the pole and the generator of permanent magnet synchronous electric current fixing it with screws using the six holes made before on the circumference with a diameter of 0.34 meters. see (table n ° 1, drawing A / 2).

Claims (1)

Claims: 1) - Vertical axis wind turbine characterized by: two turbines on the same axis, the fulcrum located in the center, the shape and offset of the sails. 2) - Vertical axis wind turbine according to claim 1, that two turbines on the same axis double the power using the same support. 3) - Vertical axis wind turbine according to claim 1, from the fulcrum located in the center, eliminating the overturning thrust exerted by the wind. 4) - Vertical axis wind turbine according to claim 1, the 60 ° offset of the sails gives it a more constant torsional force. 5) - Vertical axis wind turbine according to claim 1, the position of the sails means that the flow of air entering a sail is immediately taken over by the other sails before exiting.
