Description

Technical Field

[0001] The utility model relates to the technical field of engineering monitoring, in particular to a vibration device for underground pipeline detection. Background Art

[0002] In the prior art, pipeline detection at underground pipeline construction sites is carried out before construction. Its main task is to find out whether there are any underground pipelines already laid at the construction site. As underground pipelines develop towards greater burial depths, many problems have arisen, such as difficulty in pipeline maintenance and positioning.

[0003] After searching in the public (announcement) number: CN218645279U, a vibration device for underground pipeline detection is disclosed, including a control unit, a shock absorber, a retractable pipe, a foot support, a fixing frame, a coupling plate, a fixing, an adjusting screw, a supporting frame, and a connecting rod; the utility model provides a vibration device with various vibration forms, reasonable design, simple structure, and wide applicability. This device is used to generate a variety of vibration signals including pulse signals, and the vibration signal is excited on the pipeline. The position of the underground pipeline is determined by detecting the position of the vibration signal.

[0004] Although the above scheme determines the location of the underground pipeline by exciting a vibration signal on the pipeline and detecting the position of the vibration signal, it is inconvenient to conveniently clamp the pipeline according to the different sizes of the pipeline, and its applicability is low. Therefore, we propose a vibration device for underground pipeline detection. Utility Model Content

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, by providing an adjustment unit and a telescopic unit, when it is necessary to conveniently clamp pipelines of different sizes, first, after the side wall of the fixed coupling plate is fitted with the side wall of the pipeline, the telescopic end of the electric telescopic rod is extended and retracted, thereby driving the movable coupling plate to rotate around the fixed coupling plate, so that the inner wall of the movable coupling plate is also fitted with the side wall of the pipeline and then stops, thereby realizing convenient clamping of the pipelines according to pipelines of different sizes; when it is necessary to adjust the height according to the detection environment, the return spring can be compressed by pressing the engagement seat until the engagement seat is located in the connecting tube, and the movable rod can be moved until the distance between the movable rod and the connecting tube is suitable for the detection environment. Under the elastic force of the return spring, the engagement seat is re-engaged with the engagement hole on the surface of the connecting tube to adapt to different detection environments, thereby improving applicability.
