具体实施方式
如图 1所示, 一种流体能量提升和转换装置, 包括流管装置 1、 偏航座 2和塔筒 3, 流管装置 1通过偏航座 2固定在塔筒 3的顶部, 流管装置 1包括来流段 4、 收缩段 5和尾流段 6, 来流段 4朝向流体 的来流方向设置, 收缩段 5设置在来流段 4与尾流段 6之间, 收缩段 5内设置有机舱 7, 机舱 7内设置有传动轴 8、 固定在传动轴 8上的 传动齿轮 9和由传动齿轮 9驱动的目标耗功机组 10, 传动轴 8的两 端分别固定有一组或数组叶轮 11, 在传动轴 8上还设置有刹车 c32。
本发明可收集自然界的风能或水能,形成大功率的机械能。为了 加速增压,聚集能量,来流段 4采用口径逐渐收缩呈喇叭形的敞口结 构, 收縮段 5采用管状结构,尾流段 6采用口径逐渐扩张呈喇叭形的 敞口结构。 这样采用的双喇叭形流管装置 1, 通过设置逐渐扩张的尾 流段 6来扩大尾流空间, 使尾流段 6的流场比来流段 4的压力低,减 少湍流干扰, 有利于降低流管装置 1内的流体壅塞,对提高流管装置 1内的流体通量起到重要作用。
为更好地控制流体运动,减少湍流紊流, 在来流段 4的内侧壁上 沿顺轴向设置有多个带有螺旋旋向的向心型导流片 27, 材质为钢材 或其他硬质材料, 导流片 27还可以用导流管或导流槽来代替。
为适应极端流场条件下,避免高流速流体损坏内部设施, 在来流 段 4上设置有若干个可开闭的减压口 28, 减压口 28处设置有自动测 量装置 29和控制减压口 28开闭的控制装置 30, 当局部压力超过设 定量值时, 位于来流段 4上的减压口 28可以自动开启, 卸除内部过 高的压力。
为防止人、 动物或其他物体被快速流体卷进流管装置 1, 伤及生 命和叶轮 11设施, 在来流段 4和尾流段 6内均设置有网栅形防护网 31, 为钢材或其他材料制成。
由于流体的流向转动方向经常发生变化,为了达到最大限度地采 集能量的目的, 偏航座 2包括支承轴承 14、 固定在支承轴承 14上的 转动齿轮 15、带动转动齿轮 15转动的驱动电机 al6和与转动齿轮 15 相配合设置的刹车 al7,支承轴承 14包括固定部分 12和转动部分 13, 固定部分 12与塔筒 3的顶部固定连接,转动部分 13与收缩段 5的底 部固定连接,这样可根据流体来流方向来控制驱动电机 al6驱动转动 齿轮 15动作,调节转动部分 13转动,在流管装置 1达到预设位置时, 刹车 a17动作,锁定流管装置 1的方向,以达到最大限度地采集能量。
为了使得叶轮 11最大限度地将风能或水能转换成机械能, 如图 4所示, 叶轮 11包括轮毂 18、 辐条 19、 轮盘 20、 若干个叶片 21和 叶片转动装置 22, 轮毂 18固定套接在传动轴 8上, 辐条 19的一端 固定在轮毂 18上、 另一端与轮盘 20固定连接, 若干个叶片 21通过 叶轴 38均匀分布在轮盘 20上, 可根据流体类别和流速来设计叶片 21的形状。

如图 2所示, 当流体为风时, 除了上述结构外, 在防护网 31的 内侧还设置有防冻防雪网 33, 该防冻防雪 33网采用的是电热网。 为 了防止受雷电的影响, 在流管装置 1 的上方设置有避雷装置 34。 目 标耗功机组 10为功率为 3000kw的永磁风力发电机 37, 传动齿轮 9 通过变速箱 35来驱动永磁风力发电机 39运作。
