PURPOSE:To obtain a power generating device for a magnetic levitation vehicle with efficient power generation without affecting magnetic levitation propulsion by making pitch of a turbine and a stationary blade of at least on the upper stream side changeable so as to enable power generation in both normal and inverse directions. CONSTITUTION:Stationary blades 22 and 24 are arranged at front and rear positions of a turbine 13, and attack angle of the turbine 13 is optimized all the time by controlling either of or both pitches of the stationary blades 22 and 24 according to the speed of a vehicle 1 or the inlet wind speed of a wind passage 11. Moreover, to enable driving in both directions, a pitch variable mechanism (not shown) to make change in angle of a blade 20 of the turbine 13 the same degree to a normal variable pitch range is incorporated. Also, a sound absorbing means 30 is provided on all the inner walls of the wind passage 11. By this, a turbine type wind power generating device with efficient power generation can be obtained without affecting magnetic levitation propulsion. |
