Problems solved by technology

However, this connection method has insufficient bonding strength and is prone to connection loss.
[0008] The third is to connect the two sections of blades by laying up layers of glass fiber materials, vacuum infusion and curing. Due to the limitation of site conditions, and the long time of vacuum infusion and curing, this connection method is not easy to operate. The problem of poor economy

Abstract

The invention discloses a sectional type fan blade connecting structure, a sectional type fan blade and an assembling method. The sectional type fan blade connecting structure is characterized in that a first socket piece, a second socket piece and a fixing assembly are arranged, and the first socket piece is arranged at one end of a first blade section; the second socket component is arranged at one end of the second blade section; the first socket component and the second socket component are opposite and are arranged in a mutually crossed and staggered manner to form a connecting part, and the fixing component is arranged at the connecting part to fix the first socket component and the second socket component. According to the connecting structure, connection of the segmented blades is more reliable, the additional mass of the connecting area is light, and factory production and wind field on-site operation are facilitated.

Description

technical field [0001] The invention relates to the field of fan blade manufacturing, in particular to a segmented fan blade connection structure, a segmented fan blade and an assembly method. Background technique [0002] As wind turbine blades are designed for longer and longer lengths, the cost and difficulty of transporting them increases significantly. In order to reduce the difficulty of transportation and greatly save transportation costs, segmented blades are the main development trend in the future. [0003] Segmented fan blades have been developed at home and abroad for a period of time, but the connection of segmented fan blades at the segmented position is often complicated, the connection reliability is difficult to guarantee, and the on-site operability is not easy enough, resulting in segmented fan blades. The economy is poor, and it has not been used in actual wind farms in China. Therefore, a convenient and reliable connection method is the technology requ...
