具体实施方式
现在结合附图对本发明作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
如图1-5所示，一种采用自动控制技术的风力发电机，包括若干风叶1、齿轮箱2、塔架5、底座6、升降装置7和轮毂10，所述风叶1周向均匀分布在轮毂10外周，所述轮毂10与齿轮箱2传动连接，所述齿轮箱2设置在塔架5顶端，所述塔架5设置在底座6上，所述底座6设置在升降装置7上；
所述升降装置7包括托板17、伸缩架16、滑动销19、滑动板11、底板12、固定销13、管道14、压力泵15和液压千斤顶18，所述托板17与底座6连接，所述托板17设置在伸缩架16顶端，所述伸缩架16底端的一侧通过固定销13与底板12固定连接，所述伸缩架16底端的另一侧通过滑动板11与底板12滑动连接，所述伸缩架16通过液压千斤顶18与底板12传动连接，所述压力泵15通过管道14与液压千斤顶18连接；
所述齿轮箱2设有风叶调速装置，所述风叶调速装置包括电机20、条形齿轮21、圆齿轮22、支撑杆23、杠杆31、第一活塞30、第一液管29、导管28、第二液管27、第二活塞32、第一刹车片26、第二刹车片25和转轴24，所述圆齿轮22固定在电机20上，所述圆齿轮22与条形齿轮21啮合，所述条形齿轮21固定在杠杆31一端，所述杠杆31另一端与第一活塞30连接，所述支撑杆23设置在杠杆31靠近第一活塞30的一侧，所述第一活塞30与第一液管29连接，所述第二活塞32与第二液管27连接，所述第一液管29通过导管28与第二液管27连接，所述第一活塞30的直径是第二活塞的直径的9倍，所述第一刹车片26固定设置在第二活塞32的顶端，所述第一刹车片26与第二刹车片25相平行，所述第二刹车片25与转轴24固定连接，所述转轴24与轮毂10连接。
作为优选，为了保证压力传输的密封性，所述第一液管29、导管28和第二 液管27内充满油。
作为优选，为了实时掌握风力情况，所述齿轮箱2上设有风向标3和风速计4。
作为优选，为了提高风力发电机的可持续工作能力和方便操作，所述塔架5内部设有蓄电池8和操作室9，所述操作室9设置在塔架5底部，所述蓄电池8设置在操作室9上。
作为优选，为了保证压力传输的密封性，所述压力泵15为液压泵。
作为优选，为了提高风力发电机的智能化，所述塔架5中设有中央控制装置，所述中央控制装置包括中央控制系统37、与中央控制系统37连接的风力测量模块36、工作电源模块33、风力调速模块34、通讯模块38和升降驱动模块35，所述风向标3与风力测量模块36电连接，所述风速计4与风力测量模块36电连接，所述蓄电池8与工作电源模块33电连接，所述电机20与风力调速模块34电连接，所述操作室9与通讯模块38电连接，所述压力泵15与升降驱动模块35电连接。
风力发电机在运行时，通过风速计4进行风速测量，并将风速信息传递给中央控制装置，当风速过大时，中央控制装置同时发送命令给升降装置7和风力调速装置，升降装置7中的压力泵15开始工作，调节内部压力，通过管道14将液压传递给液压千斤顶18，液压千斤顶18的压力减小，导致与液压千斤顶18固定连接的伸缩架16开始收缩，此时位于收缩架16上的托板17高度下架，从而实现降低风力发电机的高度，保护风力发电机的塔架15免受强风破坏。
在风力发电机下降的同时，风叶转速过快，此时通过电机20转动，带动固定在电机20上的圆齿轮22转动，与圆齿轮22啮合的条形齿轮21上升，通过杠杆31将第一活塞30的位置下降，由于支撑杆23位于靠近第一活塞30的一 侧，杠杆31可将条形齿轮21下降力放大，通过液压方式带动第二活塞32上升，由于第一活塞30的尺寸小于第二活塞32的尺寸，根据液压的传递规律第二活塞32上升力将放大，带动第二活塞32顶端的第一刹车片26与第二刹车片25接触产生摩擦，与第二刹车片25连接的转轴24转速下降，从而实现风叶调速控制。
当强风天气过后，可通过操作室9对中央控制装置进行操作，分别对升降装置7和风叶调速装置发出恢复原来风机高度和停止调速的命令，工作方式与之前升降装置7和风叶调速装置的工作方式相反，调整完成后，即可继续实现风力发电机发电工作。
与现有技术相比，该采用自动控制技术的风力发电机通过风速计4测量，遭遇强风天气时，通知中央控制装置控制升降装置7进行下降操作，降低风力发电机高度，保证了风机的使用安全，同时控制风叶调速装置中杠杆31的一次放大和第一液管29与第二液管27间液压传输的二次放大，大幅度提高制动力，降低风叶1转速，延长了风叶1的使用寿命。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
