发明内容 SUMMARY

本发明目的是力求降低风动叶轮的生产加工难度及加工成本,尽量避免特大型叶轮在制造、运输、安装、维护等过程中的局限,采用化整为零的思路,提供一种方便组装的风动螺旋叶轮及其建造方法。 Object of the present invention seeks to reduce the production and processing difficulties pneumatic impeller and processing costs, limited to avoid large impeller in manufacturing, transportation, installation and maintenance process, the idea of ​​using the split-up, provide a convenient assembly its wind helical impeller construction method.

5为实现上述目的,本发明提供的组合式风动螺旋叶轮是由若干叶 5 to achieve the above object, the present invention provides a modular pneumatic helical impeller is composed of several leaves

轮单元沿叶轮转动轴线方向组装构成,所述叶轮单元至少有2个叶片,且各叶轮单元依次径向转动同样角度,形成螺旋叶轮。 Wheel unit assembly along the axial direction of the impeller rotation configuration, said impeller means having at least two blades, and each unit sequentially radial impeller rotation angle of the same, form a helical impeller. 换言之, 本技术方案所述的叶轮单元是将一个整体螺旋叶轮沿转轴方向进行等份切割后中的一个。 In other words, this aspect of the impeller means is a helical impeller for a whole aliquot after cutting along the rotation axis direction.

在上述技术方案中,所述叶轮单元由一个转毂和若干叶片构成, 叶片连接于转毂圆弧外侧,叶片相对转毂对称分布,转毂上表面设置有突起的定位销,转毂下表面设置有定位孔。 In the above technical solution, the unit consists of a rotating hub of the impeller and constituting a plurality of blades, the blade is connected to a rotating hub outer arcuate, symmetrical blades relative rotation of the hub, is provided on the surface of the rotating hub projection locating pin, rotation of the hub lower surface a positioning hole. 所述转毂还可等分为形状相同的弧形构件,各弧形构件上表面设置有若干突起的定位销,各 The transfer hub further divided into the same shape of the arcuate members, each arcuate surface is provided with a plurality of positioning pins projecting member, each

弧形构件下表面设置有若干定位?L。 The lower surface of the arcuate member is provided with a plurality of positioning? L. 对于较大螺旋叶轮,单个部件尺 For larger helical impeller, a single foot member

寸直接影响到加工难度、加工成本以及运输、安装,所以宜将转毂和叶片分开制造,减小单个部件尺寸。 Inch direct impact on the difficulty of processing, processing costs and transportation, installation, so that the rotating hub and blades should be manufactured separately, reducing the size of a single member. 对于特大型螺旋叶轮,如风力发电所要用到的特大型螺旋叶轮,有时要求叶轮单元的外径尺寸达到 For large helical impeller, such as wind power use to the large helical impeller, the impeller outer diameter is sometimes required to achieve cell

50米甚至更大,转毂直径可达到25米,对待如此庞然大物,转毂自身的等分制造拼装是必要的。 50 meters and even more, up to rotating hub diameter 25 m, so treat monster, an aliquot of manufacturing a rotating hub assembly itself is necessary. 转毂与叶片分别制造还便于对转毂直径和叶片长短尺寸做出调节,满足不同的设计要求。 Rotating hub and blades separately manufacturing also facilitates adjustments are made to the rotating hub and a blade length of diameter sizes to meet different design requirements. 如附图13、 14、 15、 16中给出了转毂直径较大的六叶片螺旋叶轮。 The figures 13, 14, 15, a rotating hub 16 is given six larger diameter helical impeller blades. 转毂直径增大, 可使风动力更多的作用于叶片外端部,以使螺旋叶轮获得较大的旋转力矩。 Rotating hub diameter increases, the effect of the wind can more power to the outer end of the blade, so that a larger helical impeller rotational torque.

在上述技术方案中,所述叶片为弧形,该叶片一立侧面为外突弧形面,该叶片另一立侧面为内凹弧形曲面。 In the above aspect, the blade is curved, the vertical side surface of a blade projecting arcuate outer surface, the other vertical side surface of the blade is concave arcuate surface. 采用此弧形叶片叶轮单元构成的叶轮,类似于传统S形叶轮固定下端,上端围绕叶轮转轴旋转所形成的s形螺旋叶轮。 This arcuate blades of the impeller using the impeller means configuration, similar to the conventional S-shaped impeller fixed to the lower end, around the upper end of the s-shaped helical impeller axis of rotation of the impeller is formed. 所形成的此s形螺旋叶轮是s形叶轮和螺旋叶轮各自特点的重合与叠加,即该s形螺旋叶轮旋转方向确定且能形成风道。 This s-shaped helical impeller is formed by s-shaped impeller and a helical impeller coincides with the characteristics of each stack, i.e., the s-shaped helical impeller rotation direction determining capable of forming duct. 所不同的是,本发明叶轮单元组合形成的s形螺旋叶轮的 The difference is, s-shaped helical impeller impeller unit formed by the combination of the present invention
