PE pipeline detector

Abstract

The invention provides a PE pipeline detector which comprises a first supporting plate, a moving assembly and a sixth supporting plate. The PE pipeline detector further comprises a transmission assembly and a signal pickup assembly. The PE pipeline detector further comprises a signal transmitter and an audio driver. Two second supporting plates are arranged at the bottom of the first supporting plate. The two ends of the first rotating shaft are rotationally connected with the two second supporting plates correspondingly. Two sets of rollers are arranged on the first rotating shaft; a third supporting plate is arranged on the first supporting plate, a fourth supporting plate is arranged at the top of the third supporting plate, and a signal analyzer is placed on the fourth supporting plate; two sets of sixth supporting plates are arranged at the bottom of the first supporting plate, a second rotating shaft is arranged on one set of sixth supporting plates, a first friction ring is arranged at the end of the second rotating shaft, a box body is arranged on the other set of sixth supporting plates, a barrel is rotationally arranged on the box body, and a first winding wheel is arranged on the peripheral wall of the barrel. According to the invention, the operation process is greatly simplified, time and labor are saved, the problem of wire winding does not exist, and the detection precision is also improved.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a PE pipeline detector. Background technique [0002] Due to historical reasons, some long-term natural gas pipelines have no drawings or engineering drawings are inaccurate, and road references have been changed or disappeared, making it impossible to know the exact location of underground pipelines. For municipal engineering pipeline cross-project construction, management methods and maintenance It is very difficult to maintain the safety of the gas pipeline network, which poses a great safety hazard to the city. PE pipelines are non-magnetic and non-conductive, so traditional detection techniques cannot detect them. For PE pipelines For the detection, the signal transmitter is generally used to transmit the signal through the pipeline, and then the matching receiver is used to obtain information, so as to obtain various information of the PE pipeline. During the operation, ...

Problems solved by technology

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a PE pipeline detector. The operator only needs to push the fourth support plate to the detection point, press the switch of the signal analyzer, and then replace the detection point to perform repeated picking. Signal operation greatly simplifies the operation process and solves the problem of high labor intensity caused by the need for the operator to hold the instrument all the time in the prior art, and there is no problem of coiling, which further reduces the labor intensity of the operator. The detection distance between the component and the signal analyzer is consistent, which improves the detection accuracy
