Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of maintenance equipment, more specifically, it relates to a heat supply pipe network maintenance equipment. BACKGROUND

[0002] In the prior art, first, the existing equipment lacks flexibility when inspecting the inside of the heat supply pipeline. Due to the complex internal environment of the heat supply pipeline, the pipeline may be curved, narrow or blocked, and the existing equipment cannot adapt to these complex situations, making it impossible to thoroughly and carefully view every corner of the pipeline interior. This may result in potential problems being overlooked, affecting the quality and efficiency of the inspection and repair.

[0003] Secondly, the existing equipment is cumbersome to disassemble and install during use. When the camera needs to be replaced or adjusted, the operator often needs to spend a long time to release the fixation of the camera, which not only reduces the work efficiency, but also may cause unnecessary delay in emergency situations.
