本发明涉及风力机技术领域，具体为一种新型风力机叶片。
 背景技术
风力机叶片是风力机组中重要的驱动组件，它将自然风力所产生的机械能转化为稳定输出的机械动力，用于驱动发电机工作发电，因而，为了保证风力机的持续运行，需要尽可能地对其叶片进行维护和改进。但现有的新型风力机叶片依然存在一定的问题，具体问题有以下几点：1、常规的风力机叶片尺寸较大，为了方便生产和运输，通常采用组合式结构，但由于缺乏便捷的定位与连接机构，通常需要采用一系列繁杂的焊接工艺进行内外固定，装配效率相对缓慢；2、为了减少能量损耗，该叶片通常为中空结构，这也导致叶片自身的可承载强度降低，为了避免叶片发生形变或断裂，需要在其内部添加有效的支撑机构；3、现有技术中，风力机叶片的造型各异，但许多设计在实际使用过程中存在不合理，例如风阻系数过低导致转动缓慢、末端涡流较大导致不稳定等问题，气动效率相对不足。
 技术问题
本发明的目的在于提供一种新型风力机叶片，以解决上述背景技术中提出装置的装配效率较低、载荷强度较弱以及气动效率不足的问题。
