Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a multifunctional rotating lens for pipeline detection. Background technique [0002] Pipelines are widely used in many industries and are closely related to people's lives. In order to improve the life of the pipeline and prevent accidents caused by damage or blockage of the pipeline, regular maintenance must be carried out on the pipeline. However, due to the complexity of the pipeline, manual inspection cannot be realized in many places, and a pipeline robot that replaces manual inspection came into being. [0003] At present, the mainstream test method for pipeline inspection is CCTV video inspection, which is to put a crawler equipped with a camera into the pipeline to be tested, watch and record the internal images of the pipeline while crawling, and intuitively distinguish the defect type, size and grade of the pipeline . The rotating lens performs video comm...

Problems solved by technology

The traditional pipeline robot lens uses an analog camera with low pixels and low definition, which cannot clearly reflect the subtle defects in the pipeline; and the traditional pipeline robot rotation lens can only rotate 345° in a circular direction, and the circular detection efficiency is low

[0004] For example, the Chinese utility model patent (notification number: CN208568573U) disclosed a pressure pipeline detection device in 2018, including a lighting lamp, a detection lens, a mounting block, a base, a tire, a spoke, a rotating shaft, a rear wheel, a lifting frame, and a control body , a rotating device, a connecting shaft, a fixed frame, and the illuminating lamp is embedded and installed on the front surface of the mounting block, and the front surface of the mounting block is embedded with a detection lens; the detection lens can be rotated through a multi-stage gear and a rotating shaft, but the rotation angle is limited. and cannot rotate continuously

[0005] In addition, after the existing inspection lens is used for a long time, or when the lens is turned on in cold weather, it is prone to fogging. If the fogging is serious, the picture will be blurred and the pipeline inspection cannot be performed, which will seriously affect the overall efficiency.

[0006] Moreover, the main purpose of pipeline inspection is to detect the type and size of defects in the pipeline, but there is no standard reference object in the pipeline, and the size of the defect can only be evaluated by the diameter of the pipeline or the size of conventional objects, resulting in the inability to accurately measure the defect in the pipeline size
