Description

Technical field:

[0001] The invention belongs to the technical field of underground pipeline detection clamps, and in particular relates to an underground pipeline detection clamp with a safety protection structure. Background technology:

[0002] The underground pipeline detection at the trenchless underground pipeline construction site is carried out before the trenchless construction. Its main task is to find out whether there are already laid underground pipelines (including water supply and drainage, gas, heat, industrial and other pipelines as well as power and telecommunication cables) at the construction site. If so, the plane position, direction, buried depth (or elevation), specifications, properties, materials, etc. of the underground pipelines should be found out, and the underground pipeline map should be drawn. In addition, the laying age and property unit of each pipeline should be found out. The purpose is to protect the existing underground pipelines and prevent damage to the pipelines during construction. Therefore, the detection range should include the entire construction area and areas that may be affected by the construction and threaten the safety of underground pipelines. During the detection, the constructors generally use pipeline detection clamps for detection.

[0003] The existing underground pipeline detection clamps use a safety protection structure at the connection between the detection wire and the wire handle, which will still have gaps in the case of thermal expansion and contraction, and the overall safety protection effect is poor. At the same time, the clamps need to be cleaned manually, which is time-consuming and labor-intensive, greatly reducing the detection efficiency. In addition, the clamps are manually clamped on the underground pipelines, which makes the operation very inconvenient when detecting some deeper underground pipelines, greatly increasing the difficulty of pipeline detection.
