Description

Technical Field

[0001] The utility model relates to the technical field of pipeline inspection, in particular to a pipeline internal inspection device. Background Art

[0002] During the heating period from 2021 to 2022, in order to solve the problem of difficult to find pipeline compensators, an electric wire-controlled pipeline vehicle was developed. The electric wire-controlled pipeline vehicle can not only find compensators, but also detect corrosion on the inner wall of the pipeline, foreign objects blocking the pipeline, etc. Before the pipeline vehicle, the search for compensators was done manually. People drilled into the pipeline to find the compensators, and had to stop searching and exit the pipeline when they encountered water. In addition, it was very dangerous due to the lack of oxygen and narrowness in the pipeline. The manual search distance was generally 20-30 meters, and multiple exploration pits needed to be dug. The pipeline vehicle can search 80 meters at a time, greatly reducing the number of exploration pits.

[0003] However, when the existing pipeline internal inspection equipment is used, if there is water or mud in the pipeline to be inspected, the resistance of the pipeline vehicle will increase after it travels inside the pipeline for a period of time, and the wheels of the pipeline vehicle will spin idly and cannot move forward. At the same time, the water in the pipeline will contact the battery of the pipeline vehicle, causing the battery to short-circuit, and the pipeline vehicle will lose power, which will have a certain impact on the efficiency of pipeline internal inspection. Therefore, a pipeline internal inspection equipment is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a pipeline internal inspection device. The utility model solves the problem that when the existing pipeline internal inspection device is in use, water and mud in the pipeline will cause the pipeline vehicle frame to be inconvenient to drive in the pipeline, and the battery and control board on the pipeline vehicle frame will lose power when encountering water, by arranging a waterproof box, a sealing layer A, a sealing layer B, a motor C, a screw rod, a drive plate, a wheel frame, a convex block, a lighting lamp and an endoscope.
