Abstract

PURPOSE:To control a windmill from below the tower by providing a current collecting system having a hollow shaft to be inserted with a vertical shaft for leading the power from the windmill installed on top of the tower to the lower portion of the tower. CONSTITUTION:A variable pitch section 9 incorporating electric machineries for varying the pitch of windmill blade 4 is provided then connect the power feed cables 10, 10' through a current collector 11 with a controller 12 installed at the lower section of tower 2. The rotary power of windmill blade 4 is transmitted through horizontal shaft 5, power shaft converter 6 and vertical shaft 7 to a generator 8 to drive it. Variation of pitch of windmill blade 4 can be operated from the lower section of tower by operating the variable pitch section 9 through a controller 12. Since the current collector 11 has hollow structure, the vertical shaft 7 can rotate at the center of turning of windmill 1 and never disturb the rotation.
