所述竖向旋转机构包括与机舱相连的转轴齿轮(6);所述马达驱动转轴齿轮旋转以改变机舱的仰角。
所述控制模块对风机的转速进行监测,若当前风速使风机转速超过阈值时,所述控制模块控制马达驱动机舱向上转动以减小叶片迎风面积,当机舱向上转动至风机转速降至阈值以内时,所述控制模块使马达停机并驱动刹车器对竖向旋转机构进行制动。
当飓风来时,所述控制模块根据测风仪测得的风速计算所需的避风角度,所述竖向旋转机构处设有角度传感器用于监测机舱仰角;当机舱向上转动时,若控制模块经角度传感器测知机舱仰角达到避风角度,则所述控制模块停止机舱上转并驱动刹车器对竖向旋转机构进行制动。
所述防飓风装置可工作于紧急避风模式,在紧急避风模式下,控制模块直接把机舱的仰角转至90度使风力发电机的叶片处于水平状态,以减少叶片在飓风中的受力从而保护叶片。
所述风叶位于机舱的前端方向处;所述紧急避风模式下机舱的上仰动作可由备用动力装置完成,所述备用动力装置为动滑轮装置或液压装置;当备用动力装置为动滑轮装置时,动滑轮装置的活动端与机舱后端相连;动滑轮装置以卷扬机驱动来拉动机舱后端使机舱上仰;当备用动力装置为液压装置时,液压装置的液压杆与机舱后端相连以拉动机舱后端使机舱上仰。
当机舱在备用动力装置驱动下上仰后以刹车器锁定其上仰姿态,当刹车器解除锁定后,机舱姿态可在机舱自重作用下向下复位。
本发明可对风力进行监测,并能通过改变风机仰角来改变叶片受风面积,从而能有效地在飓风天气中保护风机叶片。

具体实施方式
如图1-3所示,一种防飓风装置,用于在飓风环境下保护风力发电机,所述防飓风装置包括控制模块、测风仪、风力发电机的机舱1、U形架2、刹车器3、马达4;所述U形架的开口向上并以其竖向臂处的竖向旋转机构支撑机舱;当飓风来时,所述马达驱动竖向旋转机构使机舱向上转动,以减少风力发电机的叶片的迎风面积;当机舱仰角达到所需的避风角度时,所述刹车器对竖向旋转机构进行锁定以固定机舱角度。
所述竖向旋转机构包括与机舱相连的转轴齿轮6;所述马达驱动转轴齿轮旋转以改变机舱的仰角。
所述控制模块对风机的转速进行监测,若当前风速使风机转速超过阈值时,所述控制模块控制马达驱动机舱向上转动以减小叶片迎风面积,当机舱向上转动至风机转速降至阈值以内时,所述控制模块使马达停机并驱动刹车器对竖向旋转机构进行制动。
当飓风来时,所述控制模块根据测风仪测得的风速计算所需的避风角度,所述竖向旋转机构处设有角度传感器用于监测机舱仰角;当机舱向上转动时,若控制模块经角度传感器测知机舱仰角达到避风角度,则所述控制模块停止机舱上转并驱动刹车器对竖向旋转机构进行制动。
所述防飓风装置可工作于紧急避风模式,在紧急避风模式下,控制模块直接把机舱的仰角转至90度使风力发电机的叶片处于水平状态,以减少叶片在飓风中的受力从而保护叶片。
所述风叶位于机舱的前端方向处;所述紧急避风模式下机舱的上仰动作可由备用动力装置完成,所述备用动力装置为动滑轮装置7或液压装置9;当备用动力装置为动滑轮装置时,动滑轮装置的活动端与机舱后端相连;动滑轮装置以卷扬机8驱动来拉动机舱后端使机舱上仰;当备用动力装置为液压装置时,液压装置的液压杆与机舱后端相连以拉动机舱后端使机舱上仰。
当机舱在备用动力装置驱动下上仰后以刹车器锁定其上仰姿态,当刹车器解除锁定后,机舱姿态可在机舱自重作用下向下复位。
实施例:
当台风风速不强时,所述控制模块对风机的转速进行监测,若当前风速使风机转速超过阈值时,所述控制模块控制马达驱动机舱向上转动以减小叶片迎风面积,当机舱向上转动至风机转速降至阈值以内时,所述控制模块使马达停机并驱动刹车器对竖向旋转机构进行制动。
当高强度台风紧急来袭时,防飓风装置工作于紧急避风模式,控制模块直接把机舱的仰角转至90度使风力发电机的叶片处于水平状态,以减少叶片在飓风中的受力从而保护叶片。
实施例2:
本例中,机舱由卷扬机拉机舱的滑轮来转动风机的仰头,由转轴里的刹车器制动定位。低头动作,靠风机头部的自重,放开刹车器,由于风机头部的轴心下部和前部比较重,只是卷扬机转动放长铁绳,风机头部就会靠重力低头,最后再刹车制动,本例中,也可把滑轮改为液压伸缩缸。
