Abstract

The invention discloses a detection system and a detection method for blades and a hub of a wind turbine. The detection system comprises a mounting base, at least one sensor, a control device. The mounting base is used for fixing an object to be detected. The object to be detected comprises the blades and the hub, and each blade corresponds to a pitch assembly. The sensors are fixedly mounted on the object to be detected, and are used for detecting at least one of vibration data and angle data of the object to be detected when the object performs a pitching action. The control device sends a control signal to the pitch assemblies, so that the pitch assemblies drive the object to be detected to execute the pitching action, and receives the results fed back by the sensors. The detection system can detect the blades and the hub before hoisting, so as to avoid the occurrence of faults or defects of the blades and the hub after the hoisting of the wind turbine is completed, thereby reducingthe failure rate of the blades and the hub in the mounted wind turbine, therefor the stable and healthy operation of the wind turbine is ensured.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a detection system and detection method based on blades and hubs of wind turbines. Background technique [0002] Generally, a wind turbine includes a tower, a nacelle installed on the top of the tower, and a hub and blades installed at the end of the nacelle. When installing a specific wind power generating set, the tower is fixedly installed on the ground, and then the installation of the nacelle, blades and hub is completed by using the wind turbine hoisting process. [0003] Among them, when hoisting the blade and the hub, first assemble the blade and the hub together on the ground, fasten the fixing bolts, and use the blade locking device to lock the blade and the hub together to prevent the blade from being connected to the hub during the hoisting process. Relative movement occurs between the hubs, and then the overall hoisting work is performed on the blades, h...
