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.

风力发电增速机具有效率高、体积小、重量轻、结构紧凑、传递功率大、负载能力高、传动比范围大的特点。行星轮系布置紧凑，齿轮箱结构复杂，各部件关联度高。该增速机的均载装置有太阳轮少量浮动，更多是提高制造装配精度来达到均衡载荷的目的，这样给检测增加了很大难度。箱体也是封闭式包围结构，齿轮箱中若有硬金属颗粒或碎片都可能导致齿轮严重磨损。

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.

传统的检测方法费时费力，大大地影响风电企业的效益，工业内窥镜为风电检测工作提供了一种新的检测手段，小巧轻便的设计，直观的检测效果，非常适合在紧凑的发电机机舱中使用，对风电齿轮箱的检测，风电叶片检测（包括内部和外部）和风电齿轮箱内部轴承的检测等都有很好的效果。

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.
