Description

Technical Field

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

[0002] As one of the important infrastructures of the city, underground pipelines are responsible for water supply, gas supply, heating, electricity supply, drainage, communication and other functions. They are the main arteries and lifelines of the city and are closely related to the lives of the people. Due to inaccurate pipeline information, incidents of pipeline facility damage occur every day during urban construction, especially for ultra-deep underground pipelines. Due to inaccurate information provided during early construction or changes in the ground environment, accurate detection and positioning of the pipelines are required to ensure the safe and smooth progress of construction.

[0003] An ultra-deep pipeline refers to a pipeline buried at a relatively deep position underground, which is usually used to transport media such as liquids or gases. For example, an ultra-deep pipeline can be used for natural gas transportation. Therefore, detection in ultra-deep pipelines is a necessary operation to ensure the normal use of media such as liquids or gases.

[0004] When ultra-deep buried pipelines are used for natural gas transportation, an exploration hole is drilled near the metal pipeline to be detected, and the probe of the pipeline detection instrument is placed in the exploration hole. The geological radar technology is used to detect the position, depth and direction of the metal pipeline in the underground at an abnormally deep depth.

[0005] However, when the existing pipeline position detection device is in use, the detector body cannot be cleaned, and impurities or dirt will remain on the surface of the detector body, causing damage to the detector body and reducing its service life. In addition, the installation process of the detector body is relatively cumbersome, which greatly reduces the convenience of installation and thus reduces the efficiency of detection.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Specifically, a mounting hole matching the insertion rod 602 is opened inside the clamping ring 601, and the bottom end of the connecting sleeve 603 is connected to the detector body 7.

[0041] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0042] In actual application, the horizontal position and burial depth range of the target natural gas pipeline are determined in advance, and a deep hole is drilled within this horizontal position range. The auxiliary component 3 is used to place the detector body 7 inside the deep hole. The detector body 7 is used to transmit and receive radar waves to obtain underground geological information to determine the position and direction of the ultra-deep buried pipeline. The laying plane position of the natural gas pipeline is determined through the received information points. At the same time, the 80% method is used to determine the horizontal distance between the natural gas pipeline and the current deep hole. Combined with the original preliminary determination of the horizontal position of the target natural gas pipeline, a deep hole is drilled again. The auxiliary component 3 is used again to place the detector body 7 inside the deep hole to determine the laying horizontal position of the natural gas pipeline. The laying position of the natural gas pipeline is determined based on the above-determined horizontal position and burial depth.

[0043] At the same time, in order to prevent the detector body from falling off during the detection process, the detector body 7 is connected and fixed to the fixing plate 4 through the fixing component 6, so as to prevent the detector body 7 from falling into the ultra-deep pipeline during the detection process, causing equipment loss and failure of the detection work. The detector body 7 can be cleaned by the cleaning component 5 to prevent the soil or impurities inside the deep hole from damaging the detector body 7 and reducing its service life.

[0044] Specifically, the detector body 7 can adopt geological radar technology, mainly by using high-frequency electromagnetic wave scanning method to determine the structure and shape of underground target materials, so as to determine the location. The bottom-penetrating radar generates a series of electromagnetic short pulses at a certain interval through the control circuit, which are sent into the underground through the transmitting antenna from the ground in the form of broadband short pulses. The broadband short pulses are reflected by the underground bottom layer or the target body and returned to the ground. They are received by the receiving antenna and sent to the control circuit. At the same time, the computer controls the field real-time data collection. Based on the strength of the data characteristics of the reflected waveform, the characteristic Hz energy is analyzed and processed by the computer to determine whether the underground gas pipeline exists and the location. This technology prevents the distortion of detection caused by electromagnetic interference.

[0045] In summary, with the aid of the above technical solution of the utility model, the utility model has a simple structure and is easy to operate. By setting a fixing component 6, the detector body 7 can be connected and fixed to the fixing plate 4, so as to avoid the detector body 7 from falling into the ultra-deep buried pipeline during the detection process, causing equipment loss and failure of the detection work. At the same time, the detector body 7 can be replaced and maintained, and the detector body 7 can be replaced in time when it is damaged, which greatly improves the convenience of installing the detector body and improves the efficiency of detection. The utility model can drive the detector body 7 at the bottom of the cable 305 into the deep hole under the action of the servo motor 302 by setting an auxiliary component 3, and it is also convenient to take the detector body 7 out of the deep hole, and adjust the detection depth of the detector body 7 according to the detection depth, so as to meet the detection of ultra-deep buried pipelines of different depths and improve the applicability of detection. The utility model provides a cleaning assembly 5 so that the cleaning brush 510 can be driven to rotate by the servo motor 2 502, and the detector body 7 is cleaned during the rotation process to prevent soil or impurities inside the deep hole from damaging the detector body 7 and reducing its service life.
