Problems solved by technology

[0008] These devices for detecting underground pipelines are usually able to obtain two-dimensional geographic information, but cannot obtain data related to pipeline depth
Therefore, these common devices for monitoring underground pipelines have the limitation that it is difficult to effectively maintain and protect pipelines
The approximate location of the pipeline is marked on the map, but the depth at which the pipeline is buried is not, which could lead to excavation workers mistakenly damaging the pipeline

Embodiment Construction

[0039] Components and operations of the present invention will be explained in detail with reference to the accompanying drawings.

[0040] figure 1 It is a view showing an apparatus for acquiring three-dimensional geographic information of an underground pipeline according to an exemplary embodiment of the present invention, in which an in-pipeline conveying device 300 is shown. The transmission device 300 in the pipeline acquires geographic information without cutting off the water flow in the pipeline.

[0041] The in-pipe transfer device 300 moves inside the underground pipe 500 and includes a detection unit 310 that measures the direction, speed, and distance the in-pipe transfer device 300 moves, and a storage unit 340 that stores values ​​measured by the detection unit 310 .

[0042] The in-pipe transfer device 300 may be configured to have a smaller diameter than the underground pipe 500 and have the same specific gravity as the fluid flowing in the underground pipe 5...

Abstract

An apparatus to acquire 3-dimensional geographical information of an underground pipe includes an in-pipe transfer unit which moves along the inside of the underground pipe, a sensing unit which senses 3-dimensional location information of the in-pipe transfer unit, and an information storage unit which stores a value measured by the sensing unit. Accordingly, the depth at which the underground pipe is located as well as 2-dimensional location information of the underground pipe is stored in the information storage unit so that maintenance and repair of the underground pipe can be carried out with greater efficiency.

Description

technical field [0001] The invention relates to a device for acquiring three-dimensional geographical information of an underground pipeline and a non-contact moving distance measuring unit which can be installed on the device.
