Description

万向风车
技术领域
本发明涉及一种风力应用设备。
技术背景
风能是自然界中普遍存在，且很有应用价值的可再生能源，但现有的风力发电风车大都是1931年前苏联发明的螺旋桨式风车，其受风向的限制，风车必须迎风才能转动。本发明基于流体力学工作原理，无风向限制，不管是东、西、南、北风，还是上风、下风，风车都会旋转，且效率高，灵敏度高，结构紧凑，制造容易。
发明内容
一、风车结构
风车由叶片、支架和转轴等三部分组成。
单片叶片为长条形，其横截面为弧形或流线型，分凹凸两面，在单片叶片的中间处有开口，能使两叶片于中间处凹面相向地两两交叉，形成两两交叉的组合叶片。
风车支架由上支架和下支架及中间支撑部分构成，上下支架为两个“万”字形(卐)支架，上下支架平面相互平行，且与转轴垂直，上下支架各横梁一一对应，四组两两交叉的叶片分别固定在上下支架相应的横梁上。转轴位于支架中心。
二、工作原理
因为叶片的横截面为弧形或流线型，当凹面相向地两两交叉叶片侧面迎风时，凹面流速基本不变，而凸面根据流体连续性原理，流速加快，造成叶片凹凸两面流速不同。
根据伯努利方程，在同一流线上，动压强与静压强之和保持不变，因凸面流速加快，动压强增加，静压强减小，使叶片受压差作用而产生力。两叶片的合力，使叶片向凸面方向转动。
当交叉叶片凹面迎风时，风的动压强转变成静压强，从而转变成力，使叶片继续转动。
当交义叶片凸面迎风时，虽然有一部分动压强会使叶片反向旋转，但因其形状近似流线体，再加上前面叶片的阻挡和分流，这部分的力量很小，风车将持续不停地向凸面方向旋转。
三、风车特点
1、万向风车对风向没有要求，不管是东、西、南、北风，还是上风、下风，风车都会旋转。
2、如希望增加输出功率，只要设计时增加风车叶片的长度和宽度就可以(当然，也应该同时增加支架的大小)，比较方便；也可按最佳参数设计、制造出产品，然后用多个万向风车串联或并联的方法，增大输出功率。
四、应用
1、可开发成风力飞行器、车辆和船只。
2、可应用于风力发电站。
3、可制成水轮机，用于无坝电站，或潮汐发电。
4、可开发成儿童玩具，等等……。

具体实施方式
结合附图详细叙述本发明实施实例：
参见图1、图2，用长木条钉成两个十字交叉的上下支架2，再用薄木条做支承将其固定。在每一十字支架2木条的顶部，横向固定木条，制成上下支架为万字形(卐)的支架2。
用薄铁皮制成长条形半圆筒8个，在长条形半圆筒的中部开口，然后将其凹面3相向地两两交叉，制成两两交叉的组合叶片，再将两两交叉叶片固定在支架2相应的横梁上。在上下支架2的中心打孔后(上支架不要打透)，穿入转轴1，万向风车即制作成功。
