Description

Technical Field

[0001] The utility model relates to the field of fault monitoring of wind turbines, and in particular to a sensor installation and fixing device for soundprint detection of wind turbines. Background Art

[0002] With the rapid development of the wind power industry, the efficient and stable operation of wind turbines faces numerous challenges. To address the limitations of traditional maintenance methods, voiceprint detection technology has emerged. By capturing and analyzing the sound signals generated by wind turbines in real time, this technology can promptly detect equipment anomalies and predict potential failures, enabling precise maintenance, improving equipment reliability and safety, and reducing operating costs. It is a key tool for intelligent O&M in the wind power sector.

[0003] In existing soundprint detection work, construction workers usually place sensors directly near the components that need to be detected. The sensors will receive the soundprints emitted by various components of the wind turbine during operation. After analyzing the soundprints, they will draw them into a ripple diagram for intuitive observation. If a mechanical failure occurs in the wind turbine during operation, a soundprint different from the existing soundprint will appear, thus drawing a different ripple diagram, which makes it easier for construction workers to detect problems in a timely manner and carry out repairs.

[0004] In actual use, sensors are usually installed by magnetic attraction, bonding or welding. However, the use of magnetic attraction is limited to installation on magnetic metals. The bonding installation method has the risk of falling over time, and the installation method of welding is difficult to disassemble. Utility Model Content
