The utility model aims to provide a balancing sheet for a cross-flow wind turbine, including a balancing sheet, in which the balancing sheet includes an integral folding forming fitting section and a pressing segment. The folding part between the fitting section and the pressing segment is an elastic connecting part. The features of the balancing sheet are that the inner surface of the fitting section coincides with the shape of the inner arc surface of the blade and is used to completely adhere to the inner arc surface of the blade. The tail end forming of the pressing segment has a contact part which is in contact with the top of the outer arc surface of the blade, in which the gap between the contact part and the inner surface of the fitting segment is less than the thickness of the blade; the tail end of the fitting segment is folded in one direction towards its inner surface and is used for the clamping part which is clamped with the end of the blade, in which the tail end of the clamping part is folded outward in turn to form an arc edge and an arc edge. The utility model has the advantages of simple and reasonable structure, convenient installation and disassembly, good stability, etc.

一种贯流风轮用平衡片
本技术涉及贯流风轮的平衡部件,具体涉及一种贯流风轮用平衡片。
技术介绍
众所周知,对于空调器等用的贯流风轮是在电机的带动下驱动室内部分空气流动起来,对空调产生一定的风循环量,从而靠循环流动的空气来实现室内空气和空调室内机换热器之间的热量交换的,贯流风扇放置时间长的话,容易出现偏心不平衡现象,为保障风轮整体平衡夹持良好,尽量抑制伴随回转产生的振动,一般通过在风轮上安装弧形平衡片达到所需效果,但现有传统安装方式是将平衡片采用胶水粘接的固定模式,主要有两种:如图1所示,为一种无加强倒钩无胶水孔的普通型平衡片,平衡片装配后从四周滴入胶水;如图2所示,为另一种加强牢固型平衡片两边有加强倒钩,平衡片中间开孔方便胶水滴入加强胶水的粘结强度;为了将平衡片固定在风轮的叶片上,以上两种都采用了胶水粘结的固定模式,存在夹持力弱,易发生移位的问题;且在生产过程中需夹平衡片、滴加胶水、晾干台晾干胶水后装箱等繁琐的步骤,胶水粘接易发生平衡片松歪、脱落产品质量存在隐患;此外,专利CN204729354U文件公开了一种离心风机叶轮用平衡块:“包括本体,所述本体的前壁为向后凸 ...
