With the development of modernization, nondestructive testing technology has been applied in many industries, and this detection technology is mainly targeted because of its uniqueness. Hand held portable endoscope can be directly seen by the human eye, for some special environment detection, such as narrow space and large curvature space, high temperature, toxic, nuclear radiation and other eyes It is a new testing technology integrating optics, precision machinery, electronic machinery, electronic technology and micro camera technology. This non-destructive testing technology is mainly used for the surface defects of inaccessible and non visible parts. For those with large bending degree, hand-held portable endoscope can be used instead.

　　手持便携式内窥镜在进行内部查看，它在对内部勘察的时候，通过一些光纤传输照明光、显微摄像、视频信号对内部异物进行相应的放大、显示在控制显示器上面，这样的话就能实现一人操作供多人查看的效果，这些结果可以跟计算机进行连接，然后导成数据，这样的话就会更加的科学化，简单精准化。

　　Hand held portable endoscope is used for internal inspection. When conducting internal investigation, it transmits lighting light, micro camera and video signals through some optical fibers to amplify and display the internal foreign matters on the control display. In this way, the effect of one person operation for multiple people to view can be realized. These results can be connected with the computer and then converted into data If so, it will be more scientific, simple and accurate.
            

　　在风力发电方面手持便携式内窥镜具有很大的意义，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。

　　In the aspect of wind power generation, the portable endoscope is of great significance. The speed increasing equipment for wind power generation has the characteristics of high efficiency, small size, light weight, compact structure, large power transmission, high load capacity and wide transmission ratio range.

　　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。

　　The arrangement of planetary gear train is compact, the structure of gear box is complex, and the correlation degree of each component is high. The load sharing device of the booster engine has a small amount of floating sun wheel, which is more to improve the manufacturing and assembly accuracy to achieve the purpose of balancing the load, which makes the detection more difficult. The case is also a closed enclosure structure. If there are hard metal particles or debris in the gearbox, the gear may be seriously worn.

　　在实际应用，需根据不同环境条件、不同被检对象情况下应采用不同的物镜镜头、调整合适的各类参数才(如亮度、对比度、曝光时间等)能达到使用要求。

　　In practical application, it is necessary to adopt different objective lens and adjust various parameters (such as brightness, contrast and exposure time) according to different environmental conditions and different objects to be inspected.

　　手持便携式内窥镜在风电厂检测的时候可以对涡轮发动机、机身、汽车引擎、管道、船舶、风车齿轮箱、水下建筑等内部详细资料做出系统的分析，而图像的清晰度主要是跟光纤束的多少是有关联的，它再通过光纤传导，得出准确的数据，显示在计算机上，这一系列的检测程序都为风力发电厂隐患做出了重要意义，为以后风电厂的发展提供一个可靠的环境。

　　When the portable endoscope is used in wind power plant detection, it can systematically analyze the internal details of turbine engine, fuselage, automobile engine, pipeline, ship, windmill gearbox, underwater building, etc., and the clarity of the image is mainly related to the number of optical fiber bundles. It can obtain accurate data through optical fiber transmission and display it on the computer All of the testing procedures are of great significance for the safety risks of wind power plants, and provide a safe and reliable environment for the future development of wind power plants.
