Description

钢丝增强型风电机叶片
技术领域
本实用新型属于风力发电设备零部件领域，尤其与一种钢丝增强型风电机叶片有关。
背景技术
叶片是风力发电机中最基础和最关键的部件，目前世界风力发电进一步向大功率、长叶片方向发展，叶片单体长度已达到了60米以上。叶片所处的恶劣环境和长期不停的运转，对叶片提出了严格的技术性能和质量要求：比重轻且具有最佳的疲劳强度和机械性能，能经受暴风等极端恶劣条件和随机负荷的考验；叶片的弹性、旋转时的惯性及其振动频率特性曲线都正常，传递给整个发电系统的负荷稳定性好；耐腐蚀、紫外线照射和雷击的性能好；发电成本较低，维护费用低。
为适应上述要求，本公司开发了一种铸造铝合金铸造成型的风电机叶片，铸造铝合金叶片比传统风电机叶片无论刚性、屈服强度和重量指标都要好，但是为提高风电机叶片的技术性能，本公司的铸造铝合金叶片还有提高的空间和必要性。
实用新型内容
本实用新型的目的就是进一步提高铸造铝合金风电机叶片的技术性能，提供一种钢丝增强型风电机叶片。为此，本实用新型采用以下技术方案：
钢丝增强型风电机叶片，包括铸造铝合金铸造制成的叶片体，其特征是：所述的叶片体内部嵌设有多根与叶片体轴向同向的纵向钢丝。
作为对上述技术方案的补充和完善，本实用新型还包括以下附加技术方案：
所述的叶片体内部嵌设有多根与叶片体轴向垂直的横向钢丝，与所述的纵向钢丝组成网状。
所述的风电机叶片分成叶根、叶肚、叶尖三部分，三部分采用不同的铸造铝合金，相邻两部分之间形成两种铸造铝合金的熔合区。
本实用新型叶片具有以下有益效果：通过在铸造铝合金铸造成型的叶片体内嵌设钢丝，能增强叶片的抗拉性和屈服强度，可以相应减小叶片体厚度，减轻重量；在同等重量下可以加长叶片长度，从而能减小风电机对最小风速的要求，增加年可发电时间，加大了投资产出率，还可以使叶片变浆性能提高，从而提高安全系数。
附图说明
图1是本实用新型第一种实施方式的结构示意图。
图2是本实用新型第二种实施方式的结构示意图。
具体实施方式
下面结合附图对本实用新型进行详细描述。
如图1所示，本实用新型叶片分成叶根1、叶肚2、叶尖3三部分，叶根1、叶肚2、叶尖3三部分采用不同的铸造铝合金，相邻两部分之间形成两种铸造铝合金的熔合区4，叶片体内部嵌设有多根与叶片体轴向同向的纵向钢丝5。
如图2所示，作为另一种实施方式，叶片体内部还可以再嵌设与叶片体轴向垂直的横向钢丝6，纵向钢丝5和横向钢丝6组成网状。
