Embodiment Construction

[0027] Reference attached figure 1 , which shows a wind rotor 11 of a vertical axis wind turbine according to a preferred embodiment of the present invention. The wind wheel 11 includes a plurality of moving blades 13 . The blades 13 are arranged in parallel along the generatrix of the vertical cylinder defined by the wind wheel 11 . The blades 13 are connected by radial arm structures 15 to a central shaft 17 passing along the axis of the cylinder. Said central axis 17 is associated with an axis of rotation 19 of a device 21 for converting motion into electrical energy. Said device 21 is arranged inside a support structure 23 which can be stably fixed to the ground. According to the invention, each moving blade 13 of the plurality of blades comprises three elongated bodies 25 arranged in cascade, the three elongated bodies 25 being vertical and parallel to each other and to the central axis.

[0028] Reference attached figure 2 and 3 , the elongated body 25 is preferab...

Abstract

Self-starting vertical axis wind rotor (11) able to start also at very low wind speeds, for example of the order of 1 m / s, comprising a fixed support structure; a machine for converting the circular movement into electric current, associated with said structure; a vertical shaft rotatably supported by the structure and connected to the machine so that the rotation of the shaft causes the generation of electric current by said machine; a rotatable wind structure connected centrally to the vertical shaft and at the periphery to a plurality of rotor blades; wherein each rotor blade of said plurality of blades comprises three elongated bodies arranged in cascade and having the same wing profile, said elongated bodies being arranged vertical and substantially parallel to each other and to the shaft.

Description

technical field [0001] The invention relates to a vertical axis wind turbine rotor. More particularly but not limitingly, the invention relates to a wind turbine rotor belonging to the class of small or micro wind turbines having a power output of 10 to 100 kW. Background technique [0002] The most important characteristics of an exterior area for wind power generation are the speed and direction of the wind and the duration and intensity of atmospheric motion throughout the year. [0003] Overall, the documented land use for the installation of large wind turbines is relatively small for optimal conditions, ie economically advantageous. Furthermore, some wind turbines are complex and expensive devices, and the amount of land economically convenient to install such devices is very limited. In addition, large wind turbines cause problems affecting the environment and thus cannot be installed in arbitrary locations. [0004] Smaller wind turbines, on the other hand, are ec...
