Description

风力涡轮机
本发明涉及一种替代能源，它利用空气使安装在风力发电厂中的风轮旋转，从而在各种甚至最不利的天气条件(雨雪、冰雹、飓风)下发电。
2018年2月6日公布的专利RU 2644000 C1中公开的风力涡轮机是与本发明要求保护的风力涡轮机相关的现有技术，该专利中的风力涡轮机主体被制成球状。为了增加从风力机下部到整流罩上部减压区域的气流速度，导向肋制成具有倾斜度，有利于空气的运动和其从水平方向旋转到垂直方向从而穿过风轮的旋转平面。然而，不利的天气条件、风、雪和雨、被强风吹到空中的异物等，由于气象降水进入风力涡轮机的旋转平面的可能性降低了风力涡轮机的性能。
就特征组合和所取得的结果而言，与所要求保护的发明最接近的现有技术(原型)是2016年7月29日公布的专利EA 023719B1的风力发电装置。该风力发电装置的主体从底部到顶部逐渐变细。整流罩呈半球形，在气流的作用下在其上部产生真空，类似于飞机机翼的凸面。气团从压力高于风动能的船体下部运动，穿过固定有发电机并旋转的风轮平面，到达上部到整流罩，在那里压力降低。不利的天气条件、多向风、雪和雨、异物、被强风吹入的空气等使风力发电厂的运行复杂化。为保证正常的运行条件，并消除气象降水进入风轮旋转平面，整流罩沿伸缩支柱向下移动靠近环形整流罩，从而阻止降水和异物进入。该已知技术方案的缺点是整流罩与机身之间的压降较低，不能保证空气高速通过风轮平面运动，从而限制了风力发电设备的性能。
本发明所要解决的技术问题是提高风力发电厂的效率。
本发明的技术效果在于提高通过风轮旋转平面的气流速度，同时防止气象降水和异物进入风轮旋转平面。提高通过风力涡轮机旋转平面的气流速度，提高风力涡轮机的生产率，同时防止气象降水和异物进入风力涡轮机旋转平面，并在要求保护的风力涡轮机的上部产生额外的真空。为此，在半球形整流罩的下部连接了一个环形的空气动力学襟翼，当空气围绕它流动时，它会产生额外的真空，并且上半球形整流罩与风力发电装置外表面凸出的环形整流罩之间的侧向空间重叠。半球形整流罩的气动襟翼在风轮旋转平面上方创造了一个额外的真空区域。这使得可以增加空气从高压区通过风轮旋转平面的速度，并且完全覆盖了半球整流罩和环形整流罩之间的侧向空间，防止气象降水和异物进入螺旋桨的旋转平面，而整流罩不需要向下移动。
本发明通过一个实施例进行详细说明，并附有相应的附图，其中：
图1是风力发电装置的总体侧视图。
图2是风力发电装置的侧剖视图和环形气动防护罩的基本结构。
图3是风团相对于工作中的风力发电装置的运动示意图。
图4为风力发电装置在恶劣天气条件下的运行示意图。
风力发电装置(图1)由主体1组成，主体1从底部到顶部逐渐变细，安装在减震底座2上。在主体1上，侧表面-肋3垂直固定，其与锥形主体1一起用作迎面而来的气流的开放流动路径。主体1上部的侧肋3紧靠外表面凸出的形整流罩4，其立柱5上固定有半球形整流罩6，在其上部凸出部分遇风时，产生真空，在其下部具有环形空气动力罩7。在这种情况下，带有气动襟翼7的半球形整流罩6的直径超过带有凸形外表面的环形整流罩4的直径。在主体1上具有外表面凸出的形整流罩4的内侧，刚性地固定着静止的导向叶片8，所述导向叶片8的上方紧邻地固定着多叶片风轮9，多叶片风轮9刚性地安装在发电机10的垂直轴上，发电机10电连接到电池11。多叶片风轮9固定有球形整流罩12，球形整流罩12与螺旋桨9一起旋转。
风力涡轮机的工作原理如下。在有风的情况下，无论风向如何，由于风的动能而具有超压的气团会移动到半球整流罩上的减压区域6，并且在沿锥形对称体1的环形空气动力罩7上沿垂直肋3到固定叶片8导向叶片。在导向叶片8中，气流以最佳角度偏转，该角度在15到20°的范围内，并以该角度穿过多叶片螺旋桨9的叶片，产生指向螺旋桨9旋转的空气动力。
风轮9刚性地固定在发电机10的轴上，发电机在其旋转期间产生电力，并将其积聚在电池11中以进一步传输给消费者。通过风轮9的旋转平面后，气团继续移动到由风在半球形整流罩6的上部和环形空气罩7的外侧表面形成的减压区域(图3)。
半球形整流罩6的外表面、具有凸出外表面的环形整流罩4和主体1都覆盖有阳光吸收元件，无论风速或在风速不存在的情况下，这些元件都允许从太阳辐射发电。
具有空气动力学襟翼7的半球形整流罩6、具有凸形外表面、侧肋和锥形主体的环形整流罩4，增加了通过风力发电装置中风力涡轮机平面的气流速度，即使在紧急情况下：在发生飓风、暴风时，即当风速超过30m/s时，以及空气中存在异物时(图4)。
