As a green and clean energy, wind power has been widely distributed in the global market in recent years, gradually replacing the traditional high-risk and highly polluting energy such as thermal power and nuclear power. In addition, the government's periodic fund subsidies have also promoted the vigorous development of wind power. At the same time, the operation and maintenance of wind power equipment is extremely difficult due to the poor service environment and complex structural design. Looking around the world, most of the existing wind power equipment have passed the OEM warranty period, so the routine regular inspection and maintenance of wind power equipment has become particularly important.

風力發電增速機具有效率高、體積小、重量輕、結構緊湊、傳遞功率大、負載能力高、傳動比范圍大的特點。行星輪系布置緊湊，齒輪箱結構復雜，各部件關聯度高。該增速機的均載裝置有太陽輪少量浮動，更多是提高制造裝配精度來達到均衡載荷的目的，這樣給檢測增加了很大難度。箱體也是封閉式包圍結構，齒輪箱中若有硬金屬顆粒或碎片都可能導致齒輪嚴重磨損。

Wind power generation speed increasing machines and tools have the characteristics of high efficiency, small volume, light weight, compact structure, large power transmission, high load capacity and large transmission ratio range. The arrangement of planetary gear train is compact, the structure of gearbox is complex, and the correlation of various components is high. The load sharing device of the booster engine has a small amount of floating of the sun wheel, which is more to improve the manufacturing and assembly accuracy to achieve the purpose of balancing the load, which adds great difficulty to the detection. The box is also a closed surrounding structure. If there are hard metal particles or fragments in the gearbox, the gears may be seriously worn.

傳統的檢測方法費時費力，大大地影響風電企業的效益，工業內窺鏡為風電檢測工作提供了一種新的檢測手段，小巧輕便的設計，直觀的檢測效果，非常適合在緊湊的發電機機艙中使用，對風電齒輪箱的檢測，風電葉片檢測（包括內部和外部）和風電齒輪箱內部軸承的檢測等都有很好的效果。

The traditional detection method is time-consuming and laborious, which greatly affects the benefits of wind power enterprises. The industrial endoscope provides a new detection method for wind power detection. With small and lightweight design and intuitive detection effect, it is very suitable for use in the compact generator cabin, the detection of wind power gearbox and wind power blade (including internal and external) And the detection of the inner bearing of the wind power gearbox have good results.
