Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic detection, particularly to an auxiliary adjusting device for a pipeline detector transmitter. BACKGROUND

[0002] Underground pipelines are important infrastructure of a city. In recent years, due to the rapid increase of urban population, the demand for underground pipelines for people's survival has rapidly increased. Underground pipelines are always bearing important work such as urban energy supply, resource transportation and waste discharge. When some roads or areas need to be planned, updated, reconstructed and constructed, it is particularly important to find out the accurate spatial data of underground pipelines in advance. Because there is often a certain difference between existing pipeline drawings and actual pipeline conditions, before carrying out reconstruction work, existing pipeline data is usually collected and sorted, and then the underground pipelines in the working area are checked and detected by field detection to form a complete and clear underground pipeline drawing for urban planning, engineering construction, construction and urban management.

[0003] When underground pipelines are surveyed, a metal pipeline detector based on the principle of frequency domain electromagnetic method becomes the most important equipment for detecting underground metal pipelines due to its simplicity, rapidness and high efficiency. The metal pipeline detector is composed of a transmitter and a receiver. The transmitter can excite the target pipeline by direct connection method, clamp method or induction method to make the target pipeline generate induced current and secondary induction magnetic field. The receiver receives the secondary induction magnetic field and uses its spatial distribution characteristics to realize pipeline positioning and depth determination.

[0004] Compared with the direct connection method or the clamp method, the transmitter excites the target pipeline by the induction method, which has the advantages of no need for pipeline outcrop, simple use condition and flexibility. When the induction method is used, the transmitter needs to be placed on the ground, and the polarization direction of the internal transmitting coil is perpendicular to the ground and downward. However, in the process of pipeline surveying, the perpendicular downward polarization direction has poor detection accuracy, and usually the polarization direction is inclined at a certain angle with the ground, which can effectively improve the signal-to-noise ratio and surveying accuracy. However, there is a lack of auxiliary device for rotating the transmitter as a whole to change the polarization direction of the transmitter in the prior art. During the surveying process, the transmitter can only be rotated by manual holding and rotating, and then the polarization direction of the transmitter is changed, which will make the angle of the polarization direction of the transmitter uncertain and fixed during the excitation of the pipeline, and then seriously affect the stability and accuracy of the detection results of the target pipeline.
