Description

风帆式风球
技术领域：
本实用新型涉及一种附和空气动力的风帆式风球。
背景技术：
现有风电设备的风能利用装置多是螺旋桨式，大多需搭建相当高度的塔架，还需组合体，风向标，风速仪，钢丝拉索，地锚等，底座，还需用混凝土浇筑基础，毁坏和占用土地。耗费大量原材料，体积大，占地面积大。发电机高位安装，头重脚轻，安装保养维修复杂耗时。稳定性和安全性均不理想，风叶在旋转时给人一种眩晕感，且产生一定量的噪音和颤动。零部件多，易损件多，部件易松动。对风力大小有严格要求，弱风不易起动，强风又会使叶片后掠变形，时有叶片脱落事故发生，严重时会摔倒风机，后果严重。台风多发区不宜安装。风能利用率较底，发电机设计功率不易发挥到顶点，更不可做移动电源。
发明内容：
本实用新型的目的是提供一种受风面积大、推动力强大的风帆式风球。
上述的目的通过以下的技术方案实现：
风帆式风球，其组成包括：中心立轴，所述的中心立轴上端与北极圈中心点连接，所述的中心立轴的下端与南极圈的中心点连接，所述的北极圈、南极圈分别与风帆式叶片的两个45°角端点连接。
所述的中心立轴的下端延伸处通过法兰盘与发电机转子外接部分或其他传动装置连接，所述的风帆式叶片为8个。
所述的一组风帆式风球串联。
本实用新型的有益效果：
1.本实用新型的形状为地球椭圆形，是由八个向同一侧半圆弧形弯曲的直角等边三角形风帆式叶片与南北两个极圈及中心立轴所组成。每个叶片都像是鼓满了风的风帆。由于采用了这种结构形状，风帆式风球可以尽可能地有效利用来自不同方向的风。不论风从哪个叶片吹进风球，都会将风兜在风球内，使得风可以从一个叶片的聚风面传递到另一个叶片的聚风面，让风在八个叶片的聚风面之间依次传递，在风球内形成一个小气旋，气旋的能量随着球体的旋转而不断增强，动力强劲，推动风球匀速旋转。
2.本实用新型的风帆式叶片采用向同一侧半圆弧形弯曲，以便聚风面得以有效利用风能，背风面使气流加速流动，减小空气压强，减少风阻。本风球可安装成逆时针旋转，也可安装成顺时针旋转。
3.本实用新型的风帆式叶片，受风面积大，推动力强大，比传统螺旋桨式风叶片大出30％多。由八面风帆式叶片组成的风球，造型新颖，功能独特，八叶八面用风，独创聚风能于球体内，风能在八个叶片间依次传递，风能得以往复利用。随着风球的转动速度不断加快，气旋的能量也随之增强，动力强劲。风能利用率极高，强、弱风均可使用。可驱动大功率风电机，必要时可带动多个风电机。
4.风电机低位安装，易于安装保养维修。风球体积小，旋转时无眩晕感，无燥音，无污染，稳定性好，绿色环保，不伤及家畜和飞鸟。省去拉索，省去地锚，省去风标。
5.本实用新型可广泛用于各个领域，如车辆，船舶，海上平台，码头，飞机场，高速公路，桥梁，遂道，铁路，车站，广场照明，灾区临时用电，还可用做野外无噪音移动电源，供部队，油田，地矿勘探使用。这些是传统风电设备所不可比拟的，也无法办到的。本实用新型还可用于集群化风力发电场，可驱动超大功率风力发电机，必要时还可同时带动多个风力发电机。
附图说明：
附图1是本实用新型的结构示意图。
附图2是附图1的俯视图。
具体实施方式：
实施例1：
风帆式风球，其组成包括：中心立轴1，所述的中心立轴1上端与北极圈2中心点连接，所述的中心立轴1的下端与南极圈3的中心点连接，所述的北极圈2、南极圈3分别与风帆式叶片4的两个45°角端点连接。所述的叶片通过螺栓5与南极圈、北极圈固定，并在缝隙处焊接。
所述的中心立轴的下端延伸处通过法兰盘与发电机转子外接部分或其他传动装置连接，所述的风帆式叶片为8个。
可以将所述的一组风帆式风球串联在中心立轴上。
