风力发电在芬兰、丹麦等国家很发达， 中国也在西部地区大力提倡。一般 风力发电系统主要由风力发电机 +充电器 +数字逆变器组成。而风力发电机由 机头、 转体、 尾翼、 叶片组成。 每一部分都很重要， 各部分功能为： 叶片用来 接受风力并通过机头转为电能；尾翼使叶片始终对着来风的方向从而获得最大 的风能； 转体能使机头灵活地转动以实现尾翼调整方向的功能；机头的转子是 永磁体， 定子绕组切割磁力线产生电能。
风力发电机因风量不稳定， 故其输出的是 13〜25V变化的交流电， 须经 充电器整流， 再对蓄电瓶充电， 使风力发电机产生的电能变成化学能。然后用 有保护电路的逆变电源， 把电瓶里的化学能转变成交流 220V市电， 才能保证 稳定使用。

上述悬挂定位机构包括吊挂绳 3、 系留回转吊盘 4、 系留纤绳 5、 系留升 降纤绳 14和系留纤绳收放机构， 吊挂绳 3固定在飞艇 7与系留回转吊盘 4之 间， 系留纤绳 5和系留升降纤绳 14设置在系留回转吊盘与系留纤绳收放机构 18之间； 系留纤绳收放机构 18设置于地面。 系留回转吊盘 4包括通过吊挂芯 轴 25依次固定连接的吊挂盘 23、 回转吊挂盘 27和纤绳吊挂盘 26， 所述吊挂 盘 23与回转吊挂盘 27之间还设置有滚道轴承 24。
其中， 系留纤绳收放机构 18为多个， 其中， 一个设置在中心位置， 主要 用于负责飞艇 7的升降， 该负责升降的系留纤绳收放机构包括： 系留升降绳导 向轮 13和带动所述气球的升降并锁紧所述系留升降纤绳 14的系留绳升降装置 12, 系留升降纤绳 14通过该系留升降绳导向轮 13连接并导向至所述系留纤 绳升降装置 12。 其它的系留纤绳收放机构 18布置在上述中心位置的周围， 主 要用于对飞艇进行定位， 负责定位的系留纤绳收放机构进一步包括： 系留纤绳 导向轮 10和随飞艇的升降而收放并锁紧系留纤绳的系留纤绳收放装置 9， 系 留纤绳 5通过系留纤绳导向轮 10连接并导向至系留纤绳收放装置 9。 系留纤 绳 5的连接状态呈星状布置， 一端连接系留回转吊盘 4， 另一端连接系留纤绳 收放装置 18。 请参考图 5， 系留纤绳收放装置 9和系留绳升降装置 12都包括 导绳器 34、 纤绳卷筒.33、 减速机 32和制动电机 31， 述制动电机 31通过减速 机 32连接至纤绳卷筒 33，系留纤绳 5和 /或系留升降绳 14通过导绳器 34连接 至纤绳卷筒 33，制动电机 31通过减速机 32驱动纤绳卷筒 33。纤绳卷筒 33用 导绳器 34实现纤绳多层缠绕， 纤绳可选用钢丝绳。

本发明的气球悬挂高空风力发电设备，通过采用气球悬挂高空，提高风力 发电装置 2的高度， 并采用收縮导流进气风道 1获得了高风速，使得风力发电 装置 2的风动机不仅可以采用螺旋桨结构还可以采用涡轮结构，以便提高风能 利用效率。
请参考图 6， 上述风力发电装置 2为导流式风力涡轮发电装置， 其设置于 系留飞艇 7的中心位置， 位于直线导流风道 11内。 该导流式风力涡轮发电装 置包括前端的头部导流体 211， 后端的尾部导流体 220以及中间依次固定连接 在涡轮轴 217上的涡轮盘体 213和发电机 219， 所述涡轮盘体 213上固定有多 个涡轮叶片 214。 涡轮盘体 213安装在涡轮轴承座 216上， 涡轮轴承座 216装 置轴承座支架 222上， 通过涡轮轴 17将风能动力传递到发电机 219， 该发电 机 219设置于一发电机支架 223上。由于涡轮盘 213和涡轮叶片 214具有较高 的旋转速度，使发明的风力发电设备可能避开一般风力发电设备难以避免的复 杂的增速和调速装置， 直接驱动发电机 19， 从而大大简化了风力发电设备。 本发明的导流式风力涡轮发电装置通过气球悬挂提高高度获得高的风速，采用 收縮导流进气风道 1提高风速，利用前端的头部导流体 211加大风速， 从而得 到足以推动涡轮发电装置运转的高速风力。
