Description of drawings
Fig. 1 is the syndeton synoptic diagram of the utility model preferred embodiment.
Among the figure: main frame 1, touch-screen 2, switch 3, earphone interface 4, data line interface 5, data line 6, sensor 7, tin clave 8, microphone 9.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Leak locator referring to Fig. 1, comprise 1, data line 6, sensor 7 and listen clave 8, described main frame 1 is provided with touch-screen 2, one corner of main frame 1 is provided with microphone 9, the top of described main frame 1 is provided with switch 3, earphone interface 4 and data line interface 5, and described data line interface 5 connects data line 6, and is connected by the data line interface 5 of data line 6 with sensor 7 tops, the bottom of described sensor 7 has aperture, is connected and fixed with listening clave 8 by helical structure.
Leak locator described in the utility model is when being applied to hunt leak work, connect an instrument part reliable as requested earlier, the ability operate as normal, an end that is about to data line inserts main frame top data line interface and locking, the other end inserts sensor top data line interface and locking, earphone inserted earphone interface and confirm to connect errorless after, open the switch start, can enter the leak detection process.The whole leak detection process of described leak locator can be divided into four steps of four kinds of patterns, i.e. spectrum analysis pattern, filtering analytical model, accurate measurement pattern and some survey pattern.
(1) spectrum analysis pattern: the transient noise signal in the screen display 50-5000Hz scope, the scroll bar of side represents it is the noise intensity of corresponding frequency band.Volume and sensitivity all are defaulted as 10, can regulate by "+,-" on their limits, the left and right sides.
(2) filtering analytical model: 8 selection buttons of screen display, carried out corresponding frequency configuration according to 8 kinds of different actual test conditions, as 24 fixed frequencies, 50-500Hz, unknown water pipe-pan soil matter, unknown water pipe-weak soil matter, metallic water pipe-pan soil matter, metallic water pipe-weak soil matter, plastic water pipe-pan soil matter, plastic water pipe-weak soil matter.After one of them option is chosen in click, click again and enter this option.Be example with " 24 fixed frequencies ", demonstrate the selection button of 24 different frequencies, click and choose one of them then to represent to have selected the centre frequency of bandpass filter.What scroll bar was represented on the screen is the intensity of the transient noise signal of this centre frequency, the noise signal numerical value that the scroll bar right side is represented.
(3) accurate measurement pattern: the accurate measurement pattern refers to accurate detection mode, and it is in order to survey in the comparatively strong environment of noise and design.Use this pattern to need not to wear earphone, it can discharge the environment interference of noise, by the automatic seizure of the software signal that can leak.
(4) some survey pattern: some survey pattern refers to surveying the pattern that the several suspicious leakage point of investigating out carries out further analysis and judgement early stage.It is actual in order to discharge doubtful leaking be the water impact sound at threeway, valve place or the noise that underground other facility sends, thereby find real leakage point to design.Need not to wear earphone when using this pattern equally.
Use some survey pattern sensor must be fixed on certain suspicious leakage point, choose detection time (can select 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes six kinds of durations respectively), make it record the minimum value of the partition noise signal in the setting-up time automatically.
Point survey pattern is used and can be divided into following two kinds of situations:
1. sensor directly contacts with pipeline and carries out continuous monitoring.
A, pipeline current are less: no matter sensitivity is heightened or is turned down, and the curve fluctuation is little, can judge that this place nothing leaks; No matter sensitivity is heightened or turned down, the curve fluctuation is bigger, can judge that this place leaks.
The intermittent increase and decrease of B, pipeline current and amplitude are bigger: no matter sensitivity is heightened or turned down, the amplitude increase and decrease of the recess that curve forms is little, can judge that this place nothing leaks; No matter sensitivity is heightened or turned down, the amplitude increase and decrease of the recess that curve forms is bigger, can judge that this place leaks.
C, pipeline current are bigger: no matter sensitivity is heightened or turned down, profile amplitude can not be judged this leakage point always in high value, the part of should seeking a quarrel in addition monitoring.
2. sensor is placed on the bottom surface of suspicious leakage point top, carries out water use peak and the ebb continuous monitoring of two different periods, when operating in this case, sensitivity numerical value should arrange identical.
A, at same suspicious leakage point, during water use peak during the higher and water ebb of profile amplitude profile amplitude show highlyer, when proving the water ebb, because hydraulic pressure rises, the noise that leaks strengthens, and causes profile amplitude to increase, and can judge that this place leaks.
B, at same suspicious leakage point, during water use peak during the higher and water ebb of profile amplitude profile amplitude show reduction, when proving water use peak, the noise that monitors is caused by the underwater sound, external sound or other reason, can judge that this place does not have to leak.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
