Embodiment 1

[0034] see figure 2 , a pipe positioning device according to an embodiment of the present invention, the pipe positioning device includes a host 10 , a pickup 20 and a water flow regulating pulse device 30 . Wherein, the water flow regulating pulse device 30 is installed at the exposed point where the pipeline emerges from the ground, and the water flow regulating pulse device 30 is connected with the pipeline. The water flow regulating pulse device 30 is used to adjust the size of the water flow out of the pipe, so as to generate a pulse sound signal in the pipe. The pickup 20 is connected with the host 10 , and the pickup 20 is used to collect the impulsive sound signal of the pipeline on the ground, and transmit the collected impulsive sound signal to the host 10 . The host 10 receives the pulsed sound signal, analyzes and processes the pulsed sound signal, converts the pulsed sound signal into frequency spectrum and numerical value and displays it on the display screen. ...

Embodiment 2

[0044] see figure 1 and image 3 , a pipe positioning device according to an embodiment of the present invention, which is based on Embodiment 1 by adding a knocking device 40 . The percussion device 40 is installed at the exposed point where the pipeline is exposed on the ground, and the percussion device 40 is used for percussion on the pipeline to make the pipeline generate a vibrating sound signal. The host 10 is connected with the tapping device 40 , and the tapping force and tapping frequency of the tapping device 40 are controlled by the host 10 .

[0045] see figure 1 and image 3 , the working principle and usage method of the pipeline positioning device are as follows:

[0046] The percussion device 40 is based on the principle of the acoustic vibration method, and the percussion device 40 is wirelessly connected with the host computer 10, and the percussion force (making the vibration sound louder) and the percussion frequency (making the percussion sound) of th...

Embodiment 3

[0055] see Figure 4 , a pipe positioning device according to an embodiment of the present invention, the pipe positioning device includes a host 10 , a pickup 20 , a percussion device 40 and a bluetooth earphone 50 . Wherein, the percussion device 40, the percussion device 40 is installed at the exposed point where the pipeline is exposed on the ground, and the percussion device 40 is used to percussion the pipeline to make the pipeline generate a vibrating sound signal. The host 10 is connected with the tapping device 40 , and the tapping force and tapping frequency of the tapping device 40 are controlled by the host 10 . The bluetooth earphone 50 is connected with the host computer 10 by bluetooth.

[0056] see Figure 4 , the method of using the pipeline positioning device is as follows:

[0057] A percussion device 40 is installed at the exposed point where the pipeline is exposed on the ground, and the percussion device 40 is used to strike the pipeline with a certain...

Abstract

The invention discloses a pipeline positioning device and a pipeline positioning method. The pipeline positioning device comprises a host, a sound signal generating device and a pickup device; the sound signal generating device is installed at the exposed point where a pipeline is exposed to the ground and is used for making the pipeline produce a sound signal; the pickup device is connected withthe host; and the pickup device is used for acquiring the sound signal produced by the pipeline on the ground, and transmitting the sound signal to the host. According to the pipeline positioning device, the sound signal is produced by the pipeline to be positioned through the sound signal generating device; the sound signal produced by the pipeline is acquired by the pickup device; the sound signal is transmitted to the host; the sound signal is analyzed and processed through the host; the frequency spectrum and the numerical value of the sound signal are displayed; and the pipeline is positioned by comparing the frequency spectrums and the numerical values of the sound signals at different detecting points. According to the pipeline positioning device, the pipeline is accurately positioned on the ground.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a pipeline positioning device and method. Background technique [0002] Underground pipelines are regarded as the lifeline of cities, but at present, the distribution of underground pipeline networks in many cities in China is unclear. Due to the intricate burial of underground pipelines, there are many burial situations that do not match the construction drawings, resulting in the inability to correctly locate underground pipelines. Maintenance has caused troubles, waste of manpower and material resources; at the same time, because the pipeline cannot be located when the pipeline is damaged, this will also make the detection impossible, resulting in a large waste of water resources. With more and more buried pipelines and more and more applications, the positioning of underground pipelines has become an essential step. Existing methods cannot accurately locate pipeli...
