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.

　　手持便攜式內窺鏡在進行內部查看，它在對內部勘察的時候，通過一些光纖傳輸照明光、顯微攝像、視頻信號對內部異物進行相應的放大、顯示在控制顯示器上面，這樣的話就能實現一人操作供多人查看的效果，這些結果可以跟計算機進行連接，然后導成數據，這樣的話就會更加的科學化，簡單精準化。

　　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.
            

　　在風力發電方面手持便攜式內窺鏡具有很大的意義，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。

　　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。

　　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.

　　在實際應用，需根據不同環境條件、不同被檢對象情況下應采用不同的物鏡鏡頭、調整合適的各類參數才(如亮度、對比度、曝光時間等)能達到使用要求。

　　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.

　　手持便攜式內窺鏡在風電廠檢測的時候可以對渦輪發動機、機身、汽車引擎、管道、船舶、風車齒輪箱、水下建筑等內部詳細資料做出系統的分析，而圖像的清晰度主要是跟光纖束的多少是有關聯的，它再通過光纖傳導，得出準確的數據，顯示在計算機上，這一系列的檢測程序都為風力發電廠隱患做出了重要意義，為以后風電廠的發展提供一個可靠的環境。

　　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.
