Description
Technical field
The present invention relates to a kind of high-precision positioners for water pipe leak detection.
Background technique
According to Code for design of building water supply and sewerage, the buried depth in outdoor water supply pipe road is 1-2m, and length of pipe direction is every 1km
It is provided with valve, when water pipe leak, is usually hunted leak using correlator.
It is secondary that correlator includes at least a host, two highly sensitive shock sensors, two radio transmitters and one
Earphone.The working principle of correlator is summarized as follows: two sensors is individually positioned on two exposed points of same pipeline,
Sensor spacing generally can be controlled in 200m or so (spacing is related with caliber, material), when pipeline has leak, leak when test
Place can generate leak sound wave, and distally propagate along pipeline, can generation time difference △ when leak sound wave passes to different sensors
T, as long as the physical length D of pipeline and sound wave are in the spread speed V of the pipeline between given two sensors, leakage point is away from relatively close
The distance X of sensor can be calculated by X=(D-V × △ T)/2.
Since the leak detection of correlator is apart from restricted (generally 200m), if hunted leak using two valves, 1km's
Spacing has had exceeded the detecting distance of correlator.
Chinese invention patent discloses a kind of detection device for hidden leak of water pipe (Patent No. 200920212883.7), is present
A kind of common detection device, this device are made of missed stick, enlarging instrument, earpiece, and missed stick is closely affixed on water wall, are used
Fixed blending bolt locking is bound round, there are cap covers above missed stick, enlarging instrument is connected with earpiece, and the interface in enlarging instrument can
Connect the interface in missed stick；Lid is opened when use, the interface in missed stick and enlarging instrument is connected, if in missed stick
There is water pipe leak in surrounding 300m distance, just will form hydraulic pressure by missed stick and pass to enlarging instrument, using enlarging instrument
Earpiece is passed in sound amplification, can be discriminated whether in leak at this time.
The shortcomings that above-mentioned apparatus, is, missed stick is tightly attached on water wall, first pre- water gage glass leakage point, so
Road surface is excavated afterwards, if 300m apart from inner conduit does not have leak around missed stick, then road surface is dug with regard to white, obtains and looks for test again
Point excavates road surface and listens leakage, even if 300m apart from inner conduit has leak around missed stick, how precise positioning is also a difficult point.Have
Maintenance personnel improves method, excavates two road surfaces insertion missed sticks, and by two sensors of correlator respectively with missed stick
Connection, thus precise positioning, however this method has the following problems, due to the detecting distance of correlator be it is conditional, it is how quasi-
Confirmation water pipe leak source can also may dig several points when leak detection more and be detected between two missed sticks.
To sum up, existing water pipe cannot be accurately positioned, and at high cost, great work intensity in leak detection.
