| 摘要 |
The present invention pertains to a wind turbine (1) for converting wind into mechanical energy, comprising a support (5) and a vane (6,16) rotatively connected to said support (5), the vane comprising a wind receptacle (7) that can adopt a first configuration when the vane (6, 16) is in a position to travel in the direction of the wind, in which first configuration the receptacle (7) has a first capacity to convert wind force into motion of the vane (6, 16), and a second configuration when the vane (6, 16) is in a position to travel against the direction of the wind, in which second configuration the receptacle (7) has a second capacity to convert wind force into motion of the vane (6, 16), the second capacity being lower than the first capacity, wherein the turbine is provided with a means (200, 200') that is operable to force the receptacle (7) to adopt at least one of the said configurations independent from the direction of the wind. The invention also pertains to the use of the wind turbine (1) for converting wind into work, and to a vane (6, 16) for use in the wind turbine. |
