ALL DIRECTION ONCE-THROUGH FAN DRIVEN GENERATOR

摘要

PURPOSE:To avoid damage automatically when not using especially under typhoon by loosening the belt stretching device in servo motor drive system and closing l gates through a turn reset spring. CONSTITUTION:Wind supply gates are arranged in circular at the outercircumference of an once-through windmill provided on a vertical supporting pipe where springs will function onto plural gates in fully closing direction. Furthermore, each gate is provided with a sprocket wheel 40 to be interlocked with an endless chain 41. V-pulley 61 is provided to one of said gates while a belt 68 to be functioned with a stretching pulley 63 is entrained over the pulley 62 of servo motor 81 thus to control the opening of gate. Upon deviation of the wind speed over specific range under typhoon, for example, it is detected to release the stretching pulley 63 thus to close the gate through function of spring.
