AI Technical Summary
Technical Problem
The existing cross-flow fan blades have an insufficient contact area between the blades and the disc during welding, resulting in weak welds, incomplete welds, and affecting the stability and service life of the fan blades.
Method used
A connecting structure is set at the second end of the blade to enhance the connection strength between the blades, and an annular groove and blade groove are set on the disk to increase the welding area and stability. Ultrasonic welding technology is used to improve the welding quality.
Benefits of technology
It improves the durability and reliability of the wind turbine blades, reduces the possibility of blade deformation and incomplete welding, and enhances the strength and service life of the welds.

Abstract
本发明提供一种贯流风叶及具有该贯流风叶的贯流风机，贯流风叶包括依次连接的多个中节风叶，中节风叶包括圆盘、连接结构和多个叶片；叶片具有第一端和第二端，第一端与圆盘连接，第二端向圆盘的轴向方向延伸，相邻叶片的第二端分别通过连接结构连接，连接结构背离圆盘的端面为第一端面，第一端面与相邻中节风叶的圆盘连接；第一个中节风叶的第一端面分别与第二中节风叶的环形凹槽连接，第一个中节风叶的叶片分别与第二个中节风叶的叶片凹槽连接。本发明通过在叶片的第二端设置连接结构，可以增强叶片之间的连接强度，使得整个风叶在运转过程中更加稳定，避免放置过程中容易变形。
