Description

Technical Field

[0001] The utility model relates to the technical field of noise collectors, in particular to a fan blade noise collector. Background Art

[0002] At present, the fault detection of key components such as wind farm blades mainly relies on on-site listening and visual observation. Since wind farms are often located in remote areas such as mountains and islands, it is difficult for maintenance personnel to observe on site in time due to traffic and weather, which makes it difficult to find faults in time. When they are found, they often have destructive consequences. Based on this, a collector is usually used to collect the noise of wind turbine blades. However, since the collectors are arranged in relatively harsh outdoor environments, various emergencies will be encountered during the collection process. The most common one is the impact of the force generated by the wind on the collection equipment, which will cause the collector to fall over and affect the collection effect. For this reason, this application proposes a wind turbine blade noise collector. Utility Model Content
