一管道内窥镜的检测环境要求

Requirements for the detection environment of a pipeline endoscope

管道视频内窥镜不适合水下操作。当现场条件不能满足时，应采取措施降低水位，以管道内水位不超过管道直径的20％。

The pipeline video endoscope is not suitable for underwater operation. When the on-site conditions cannot be met, measures should be taken to lower the water level, so that the water level inside the pipeline does not exceed 20% of the pipeline diameter.

当管道内水位不符合管道内窥镜的要求时，检测前应对各种管道系统实施封堵导流，使管内水位可以满足目标检测技术要求。

When the water level inside the pipeline does not meet the requirements of the pipeline endoscope, various pipeline systems should be sealed and guided before detection, so that the water level inside the pipeline can meet the technical requirements of target detection.

在结构检查前进行疏通和清洁。

Clear and clean before structural inspection.

当有下列情形之一时应中止检测：

When one of the following situations occurs, the detection should be terminated:

当管内窥镜镜头不能在管内行走或推杆不能在管内前进时

When the endoscope lens cannot move inside the tube or the push rod cannot move forward inside the tube

管道内窥镜的镜头沾有污垢时；

When the lens of the pipeline endoscope is contaminated with dirt;

管道进行内窥镜镜头可以浸入水中时；

When the endoscope lens of the pipeline can be immersed in water;

管道充满雾时，影响图像质量

When the pipeline is filled with fog, it affects the image quality

其他原因不能正常检测时。

When other reasons prevent normal detection.
