Abstract

用双端有轴的发电机1，铸框轴座6，上、下轴2，组成上下H型风轮共驱发电机发电。左右两组(A和B)的双层H型风轮共用三角架7，用下轴承8，上轴承9自由地附装在三叶水平轴风电的塔架腰部，这样利用组合使两种不同类型风力机发挥优势互补，实现节约资源多发电。

Description

H型三叶双层风电
本发明是风电领域，是用H型三叶双层风电机组，附装在水平轴三叶风电机的高塔架腰部，使互相组合、优势互补，提高风电设施利用率。
目前，水平轴(卧轴)三叶风力发电机似乎都把塔架独占独用，未曾组合利用。本发明利用这高耸的塔架，辅以中腰拉索张拉，强化抗风载荷。
图1，在水平轴三叶风轮塔架腰部后侧左右各装一组双层H型、同型号立轴风电机组，但左组A与右组B的竖翼的上下方向互为倒装，目的使(鸟瞰图中)A组逆时针转，B组顺时针转；A组、B组的旋转风轮的逆风向受风阻的半圆周，处在塔架的塔影效应区，减少风阻功耗。A、B两组共一三角架7，用上、下轴承9和8自由安装在塔架11腰部，自行对风(下风向)。
图2是截面图，双点划线表示Aa和Bb两块导流板，(图3)导流使θ角增大——扩展做功区；同时强化塔影效应，给H型风轮的正风阻变为负风阻——提高旋转力矩，增加发电功率。
图1，双端有轴(两端盖都伸出轴)发电机1，上联轴节兼刹车盘1a，下联轴节1b，通过1a和1b与上、下轴2联接成同一轴线，上、下轴2都用毂4，焊接叶撑3与三片竖叶5构成H型的上下风轮，同轴线同方向转，只是安装、定位时把上下各个风轮的互间120°的三竖叶，在投影图上相对转过60°圆心角形成互间60°的六竖叶的投影。这样改善上下双层风轮组合的起动，运转性能，且因同样的扫掠范围中叶片少(如比五叶)质量轻，节约耗材，增加转速和功率。铸框轴座6带有上、下轴承座6a(上、下6a同一轴线)，它的投影图中轴承座6a处在铸框轴座6的左右两个面形成夹角的顶部；铸框轴座6用多枚螺钉紧固在三角架7的外伸转角处(参阅图2)。
三角架7兼作通道是金属结构，围护结构用复合材料和透明树脂材料，上、下轴承9和8的内圈都套紧在塔架锥筒外，下轴承8的外圈有一凸缘8a，搁住三角架7，用半圆弧钢板7a与三角架7用螺栓合抱紧轴承8外圈。上轴承9的外圈左右铸有两凸块，用作紧定拉杆10的螺纹销。11是塔架，12是后增设的拉索。
图3，A和B表示左右两组同一型号的H型双层风力机(转向相反，空心箭头表示旋向)，W是风向(三叶风轮此时未必在转动)。
优点：①利用了高耸的塔架腰部，更加发挥H型起动风速低，适应风速范围广的特点；②用上下线同轴线，中间电机的结构紧凑和上下三竖叶组合成圆心角为6叶起动作用的、较轻的风轮，提高效率，节省耗材；③如图3所示的用导流板Aa、Bb强化和利用塔影效应为有益作用；④由于利用了塔架，组成两种风电的优势互补，强化三叶卧轴风电发展优势和促进H型风力机发电优势互补，提高了风电场土地利用率、节约风电耗材、基础设施、输变电设施，提供更多电能以及缓和对电网的停机、开机冲击。
