Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by embodiment.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of sound wave pipe leakage positioner, including being separately mounted to pipeline head end and pipe
The monitor 1 of road end, described monitor 1 includes installing union joint 2, sound wave sensor 3 and explosion-proof shell 4, described explosion-proof shell 4
Inside it is provided with voice band data harvester 5, signal conditioner 6, shielding line 7, described voice band data harvester 5 and remote control terminal
8 connect, and are additionally provided with alarm lamp 9 outside described explosion-proof shell 4, and described alarm lamp 9 is connected with voice band data harvester 5,
Described sound wave sensor 3 includes piezoelectricity ultrasonic emitter 31, separate type piezoelectricity transceiver 32 and Single Chip Microcomputer (SCM) system module 33, institute
State and in Single Chip Microcomputer (SCM) system module 33, be provided with power module 34 and analog-to-digital conversion module 35, described piezoelectricity ultrasonic emitter 31,
Separate type piezoelectricity transceiver 32 is connected with analog-to-digital conversion module 35 respectively, described analog-to-digital conversion module 35 and voice band data harvester
5 connect, and are respectively arranged with gps receiver in described voice band data harvester 5 and remote control terminal 8, and described shielding line 7 is five
Core polrvinyl chloride shielded cable, the monitor 1 on described pipeline is other is provided with Pressure gauge 10.
Operation principle of the present utility model is as follows:
During use, head end and end at pipeline are respectively mounted monitor 1, and monitor 1 middle pitch wave sensor 3 is by wherein
Piezoelectricity ultrasonic emitter 31, separate type piezoelectricity transceiver 32 launch and collect signal, thus the pressure of collection conduit, stream
Value, as the aided assessment parameter of leakage monitoring.
When pipeline ruptures, in pipeline, the medium of conveying and pipe friction produce sound wave concussion, and sound wave is along pipeline
Interior fluid is propagated at a high speed to pipeline upstream and downstream, and the separate type piezoelectricity of the monitor 1 middle pitch wave sensor 3 being arranged on pipe ends is received
Sending out device 32 monitor and catch sonic waveforms, transmitted to voice band data harvester 5 by analog-to-digital conversion module 35, voice band data is adopted

Give birth to the size of leakage and leakage rate, if leaking, then fed back to voice band data harvester 5, and trigger alarm lamp 9 work
Make.
Sound wave signals from leakage point to the monitor 1 being arranged on pipe ends propagate time, according to arrive pipe ends time
Between difference and sound wave propagate speed can be with the position accurately determining leakage point.Ranging formula is as follows:
X=(L+V t)/2
Wherein:
X is the leakage point distance away from head end sound wave line leakage instrument, m；
L is the total length of pipeline, m；
V is to manage the spread speed of sound wave, m/s in defeated medium；
T is the time difference that upstream and downstream sensor receives sound wave, s.
Above in conjunction with accompanying drawing, detailed description of the invention of the present utility model is explained in detail, but this utility model is not
