Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
Referring to Fig. 1, underground piping track positioning device provided in an embodiment of the present invention, comprising: be used for and underground piping
Wall collision generate parts of impact acoustic waves detection device 1, acoustic location device 2 and display 3, the output end of acoustic location device 2 with
The input terminal of display 3 is electrically connected.
When it is implemented, detection device 1 is put into gas pipeline by combustion gas inspection-pit, detection device 1 is in fuel gas conduit
In road under the action of gaseous-pressure and flow velocity, moved along the direction that underground gas pipeline is laid with, mistake of the detection device 1 in movement
The metallic walls collision of Cheng Zhongyu gas pipeline generates parts of impact acoustic waves, the sound that 2 real-time reception detection device 1 of acoustic location device issues
Wave, and the position that parts of impact acoustic waves generates is positioned, so that positioning result is shown on the display 3, and is collided according to different moments

Mark.
By above-mentioned specific implementation process it is found that being equipped with detection device 1 and sound wave positioning device 2 in the present embodiment, due to
The penetration power of sound wave is stronger, will not be shielded by the metallic walls of gas pipeline, therefore, passes through detection device 1 and gas pipeline
Metallic walls, which collide, generates parts of impact acoustic waves, ensure that acoustic location device 2 can real-time reception touched to what detection device 1 generated
Sound wave is hit, and the position for the parts of impact acoustic waves that detection device 1 generates in gas pipeline is accurately positioned；Moreover, because sound
The output end of wave positioning device 2 is electrically connected with the input terminal of display 3, so that positioning result real-time display is on the display 3, energy
It is enough to obtain motion profile of the detection device 1 in gas pipeline accurately to get the track of underground piping is arrived.
In addition, due to detection device 1 in gas pipeline gaseous-pressure and movement velocity is very fast under the action of flow velocity, can
Relatively long distance is moved in gas pipeline in a short time, therefore, the track of underground piping can be quickly obtained.
Specifically, when detection device 1 is put into gas pipeline from combustion gas inspection-pit, due to the pressure in gas pipeline
Larger with flow velocity, biggish pressure and flow velocity can be such that detection device 1 quickly moves in gas pipeline, result in detection device
1 frequency to collide within a very short time with the metal pipe-wall of gas pipeline is more concentrated, and detection device 1 is made to issue sound wave
