Multifunctional rotary lens for pipeline detection

Abstract

The invention discloses a multifunctional rotating lens for pipeline detection. The multifunctional rotating lens comprises a lens main body, a rotating assembly and an electric control unit, whereinthe lens main body comprises a movement, a glass lens, a lens electric heating wire and a laser beam. The lens main body is fixedly connected to a base through a support plate; the rotating assembly comprises a vertical motor arranged on the base and a rotating motor arranged below the base; one end of the electric control unit is rotationally connected with the base, and an aviation plug is arranged at the other end of the electric control unit; a circuit control board is arranged in the electric control unit; the rotating motor is arranged in a cylinder body in a sleeving manner; the lens electric heating wire, the laser beam, a signal line of the movement, the vertical motor and the rotating motor are all electrically connected with the circuit control board. The rotary lens is compactin structure, ingenious in appearance, good in sealing performance, high in detection definition, capable of continuously rotating for detection, wide in detection range and high in efficiency, and has demisting and measuring functions.

Description

Technical field [0001] The invention relates to the technical field of pipeline detection, and 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, the pipeline must be regularly maintained. However, due to the complexity of the pipeline, manual inspection cannot be achieved in many places, and a pipeline robot that replaces manual inspection has emerged. [0003] At present, the mainstream testing method for pipeline inspection is CCTV video inspection, which is to put a crawler equipped with a camera into the pipeline to be tested, and watch and record the internal image of the pipeline while crawling, and intuitively distinguish the defect type, size and level of the pipeline . The rotating lens communicates with the crawler and ...

AI Technical Summary

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
