WIND TURBINE

摘要

A wind turbine is provided to overcome the low conversion rates of existing thermal wind turbines, which are unable to meet the growing demand for power. A wind turbine tower (7) is provided with a shaft (3) that extends vertically from the bottom or the middle of the tower to the top of the tower. The top end of the shaft is connected to the rotation shaft of a generator (2). A flywheel (4) is provided at the bottom of the shaft (3). Air inlets (8) are provided about the tower wall at the bottom of the tower and are oriented upward. A screw flight (31) is provided about the shaft, spiraling upward from the bottom to the top thereof. The wind turbine reduces loss of wind power, makes full use of wind energy, and achieves wind-to-power conversion rates of at least 85%.

1. A wind power generation apparatus, with a wind power generation tower in chimney form having an inner diameter at a bottom of the tower larger than an inner diameter at the top of the tower, a generator arranged at the opening of the top of the tower, a wind permeable canopy arranged on the top of the tower, the apparatus comprising:
the tower for wind power generation has a shaft from bottom of the tower or from within the tower to the top of the tower, a top end of the shaft is connected with a rotor of the generator, a wheel arranged at a bottom of the shaft, a plurality of wind inlets are arranged upwards at the bottom of the tower along a circumference of a wall of the tower, a plurality of vanes are arranged in an upward spiral way from the bottom of the shaft to a top of the shaft; multiple shafts are installed in sections in the tower, with one generator installed at each top of shaft, each generator transmits electrical power via a transmission line to a power distribution room, with a portion of the electrical power from the power distribution room coupled to a electric heating radiator; the intervals provided between two neighboring vanes from bottom to top are in descending order; a diameter of the vanes decreases as the vanes move upwards, the edges of the vanes spaced apart from the wall of the tower by 0.001˜1 mm.
