Safety device for wind force prime mover
专利汇可以提供Safety device for wind force prime mover专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve safety by disengaging a lock mechanism to provide blade pitch not producing turning force without any other power such as electricity, hydraulic pressure, etc. and stop the rotation so that the blade is not returned to the original position by its own force when the rotation of a wind mill is speeded up excessively by gust or the like. CONSTITUTION:When blade pitch control cannot follow abrupt increase of wind speed due to typhoon, gust, etc. and the rotation of blade is abruptly increased to dangerous rotational frequency, rollers 18 interlocked with each other are expanded to the outer periphery and disengaged from a concave groove 15a in a cylinder head 15 by the centrifugal force of weights 16. When a lock mechanism is released, a movable plate 8 is forcibly attracted toward a disk 6 by a pitch spring 12 and air force of wind mill blade 4, while providing the blade pitch of the wind mill blade 4 so as not producing turning force through a control shaft 7, connecting rod 10 and blade shaft arm 11 to stop the wind mill.，下面是Safety device for wind force prime mover专利的具体信息内容。
