Abstract

一种H型双叶四层风电机，左右两组(即A和B组)共一三角架7，用上、下轴承9和8，自由地附装在水平轴三叶风轮塔架11腰部，自动对风下风向，与水平轴三叶风电机共用一个风电场的土地、基础设施和输变电系统，节约资源，提高发电量。

Description

H型二叶四层风电机
本发明是风电领域，是利用水平轴三叶风轮塔架腰部，装两台H型二叶四层风电机，提高资源利用率和发电量。
水平轴三叶风电的优势可说人人都承认，不过，也更应该托展其优势，更符合国策，节能降耗、节约资源提高效益。
图1，利用空旷、高耸的塔架腰部后侧，左右各附装一组H型二叶四层风轮电机，而使左组A、右组B的竖翼的上下方向互为倒装，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，减少风阻损耗。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是三角架7鸟瞰示意图，W是风向，双点划线Aa和Bb两块导流板，(图3)表示一竖翼由于导流使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联成同一轴线，上轴2用两个一字撑毂3(同一产品)、一个十字撑毂4与四片竖叶5(同一产品)用螺栓连接安装(其结构请求您见下一申请“叶片制造工艺”)构成上风轮，下风轮也完全一样，只是下联轴节1b定位时把上下各风轮叶互隔90°四竖叶，在投影图上相对转过45°圆心角，形成八叶互隔45°的投影，藉此提高起动力矩和运转平稳性能；且因同样的扫掠范围中叶片少(如比四叶、五叶)质量轻、转速高，符合节约材料多发电原则。
铸框座6带有上、下轴承座6a(上、下6a同一轴线)，它的投影图2，轴承座6a处在铸框座6的左右两个面形成夹角的顶部；铸框座6用多枚螺钉紧固在三角架7的外伸转角处。
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的内圈都紧套在塔架锥筒11外，下轴承8的外圈有一凸缘，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H型四层双叶风力机(空芯箭头表示旋向)，W是风向(水平轴三叶风电机此时未必在转动)。
优点：①H型四层风轮、以上下两风轮轴在铸框座中的发电机同轴线联接，增强上下风轮轴同轴度刚度；②H型四层风轮，每层只用二片叶，所以叶片少、质量轻、转速高、耗材少、功率大；③四层风轮八片叶，形成互隔45°的投影，起动力矩大，运转平稳；④两种风电互相依存利用，提高风电场土地利用，节约材耗、基础设施、输变电设施，提供更多电能。
附图说明：
图1是H型两叶四层风电附装在塔架上的立体图。
图2是三角架的鸟瞰示意图。
图3是利用塔影效应(一片叶)的示意图。
