The assembly of the blade and the hub is an important step of the wind driven generator, wherein after the blade is connected with a variable-pitch bearing on the hub, the blade root bolt is fastened by rotating the blade, and a locking device is adopted to lock the blade to prevent the blade from rotating when torque is applied. Because the quantity of the blade root bolts is large, and in order to ensure the bolt fastening effect, the blade root bolts need to be pre-tightened twice, and frequent rotation and blade fixing are needed during installation, so that the locking device is required to be safe and reliable, and convenient to operate, and the workload is reduced. At present, a locking device mainly adopts a bolt for fixing a blade root to fix the blade.

In the manufacturing process of the wind motor blade, the blade is divided into two halves and respectively molded in two molds, and then the two halves of the molds are combined to bond the blade into a whole.

During this time, the stress at the bonding site fluctuates due to heat release of the adhesive or the like. Therefore, there is a need to provide a reliable mold locking mechanism. Currently, the mold locking mechanisms used by blade manufacturers are manual bolt-type locking and hydraulic automatic locking. The manual bolt type locking utilizes the pretightening force of the bolt to lock, has simple structure and small volume, is inconvenient to operate, and is easy to wear when the thread is repeatedly used for a long time. The hydraulic automatic locking device uses a hydraulic device for locking, the hydraulic control device has numerous accessories and complex structure, and the cost for manufacturing the device is high; the hydraulic system is large in size and causes certain interference to other operations; the hydraulic device is installed in a floor type mode, the installation position has high requirements, and the hydraulic device needs to be installed in a repositioning mode when the die moves; the hydraulic system is difficult to maintain, and long-time production stop can be caused by faults.
