wind power plant with a low environmental impact

摘要

Wind power plant with low environmental impact, comprising a tubular duct (1) carrying at one end a turbine (2) and means (3) to transmit the rotation of the turbine (2) to an electricity generator (4) supported at the centre of the duct (1), the duct (1) being supported so that it can rotate about the central vertical axis thereof, on rotation supports (5, 105) inside a trench (F) that extends opening from one side of a mountain ridge to the other, said tubular duct (1) being composed of a plurality of coaxial sections (101, 201, 301) connected to each other telescopically, which in the position of extension of the telescoping tubular elements extend from one end of said trench (F) to the other, while in the retracted position thereof the horizontal footprint is drastically reduced so as to allow them to rotate inside the trench (F) in a horizontal plane with any angle from 0 to 360° to position the end of the duct (1) carrying the turbine (2) with optimal orientation with respect to the direction of the wind, characterized in that it comprises a motor (8) that controls the rotation of said duct (1) by means of a drive shaft (108).
