Description
Technical field
The utility model relates to a kind of leakage listening device, particularly a kind ofly can be directly listens the leak vibration type leakage listening device of position of the water pipe of burying underground under the geodetic by shake sheet amplification principle on the ground.
Background technique
Underground a lot of water pipes of burying underground, because of all easily producing hole, for a long time corrosion or other reasons (building as various) water pipe cause leaking, if can not locate the position that leaks of water pipe in time, exactly, will produce unnecessary waste to water resources, increase the weight of the deficient phenomenon of water resources.In addition, foggara leaks for a long time and also may cause water pollution, and the healthy of people constituted a threat to.If disaster also can be caused in the ejection ground that leaks of water pipe.For avoiding these adverse consequencess, just need in time to survey and locate the accurate position that water pipe leaks, provide accurately effective technical support in time repairing water pipe.
The mode that addresses the above problem at present is normally: adopt photovoltaic principals that pipeline is surveyed.This survey meter all has emission, reception unit and signal conversion, processing circuit, and the complex structure of instrument own is not easy to operate, and manufacture cost is high, use to be equipped with power supply, and after the instrument damage, easy-maintaining not.In the open air, the electronic circuit of survey meter inside is subject to the interference of outer signals (vibrations, noise or the electromagnetic instrument of various emission of getting on the car as the road surface), and instrumental resolution is reduced.
The model utility content
The purpose of this utility model is to provide a kind of vibration type leakage listening device at existing shortcoming of existing survey meter or deficiency, this leakage listening device can adopt the mode of surveying of directly listening, and surveys the position whether foggara water leakage fault and water leakage fault take place easily.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vibration type leakage listening device, it comprises vibrations chamber 1, voice conducting pipe 2, the first shake sheet 3 and the second shake sheet 5.Vibrations chamber 1 comprises loam cake 11 and goes to the bottom 12.Loam cake 11 12 is fastened and connected by bolt 15 with going to the bottom, and forms cavity 13.The first shake sheet 3 and second shake sheet 5 parallel being hung in the cavity 13, and and the heavily stone roller 6 that is arranged between the first shake sheet 3, the second shake sheet 5 rivet.The surface of loam cake 11 is provided with the connection nipple 4 that is communicated with cavity 13.One end of voice conducting pipe 2 with connect mouth 4 and be connected, its other end is connected with receiver 21.
During use.To go to the bottom 12 is placed on and detects on the ground, if underground water pipe has water leakage phenomenon, its faint sound wave that sends reaches ground, and the vibrations by the outstanding shake sheet of establishing 3, the second shake sheet 5 in the cavity 13, sound is amplified heavily cutting or polish jade with an emery wheel under 6 the effect.The inspector can hear sound in the cavity 13 through voice conducting pipe 2 by receiver 21, thereby finds that water pipe leaks.
Use the utility model to be attached to and listen survey on the ground, can find the pipe leakage position.The maintenance man just can in time repair leaking pipe, the secondary disaster that reduces resources loss and produce because of leaking.
By above technological scheme as can be known, the utility model can utilize attaching to listen the mode of survey to find the pipeline that leaks on the ground by the enlarge-effect of shake sheet easily, makes the detection personnel determine the position of leaking pipe easily.The utility model is simple in structure, and easy operating is easy to carry during field work, and is more cheap than the survey meter of import.This device does not have electronic section, so can not be subjected to the interference of extraneous electronic signal when using, higher resolution is arranged.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment provided by the utility model.
Embodiment
Below, also with reference to the accompanying drawings the utility model is described in further detail by embodiment.
Fig. 1 is the structural representation of a preferred embodiment provided by the utility model, among the figure, vibrations chamber 1 by loam cake 11, go to the bottom 12 and the collar 14 that is provided with in middle part ring week be fastened and connected by bolt 15 and form, form cavity 13.
The boundary dimension of the collar 14 is identical with the boundary dimension in vibrations chamber 1, and its internal diameter size is identical with the internal diameter size of cavity 13.
The edge of the first shake sheet 3 is clamped between the loam cake 11 and the collar 14, and the second shake sheet 5 and the first shake sheet 3 be arranged in parallel, and its edge is clamped in the collar 14 and goes to the bottom between 12, thereby, the first shake sheet 3, the second shake sheet 5 are hung in the cavity 13 by parallel.
Be provided with one and heavily cut or polish jade with an emery wheel 6 between the first shake sheet 3 and the second shake sheet 5, this heavy stone roller 6 is by rivet 7 and two shake sheet riveted fixing.
In the present embodiment, two shake sheets all adopt the latten brass sheet to make, so that obtain vibrating effect preferably.
Be provided with the connection nipple 4 that is communicated with cavity 13 on the surface of loam cake 11.Be connected with an end of voice conducting pipe 2 on the connection nipple 4, the other end of voice conducting pipe 2 is connected with receiver 21.
When sound wave reached in the cavity 13, the lower surface in vibrations chamber 1 can be experienced the sound wave that water pipe leaks and produces, and at this moment, two shake sheets in the cavity 13 will be with thallium 6 vibrations emphatically, and simultaneously, the air in the cavity 13 produces vibration accordingly; Air vibration transmits by receiver 21 sound wave to the inspector, thereby finishes determining the pipe leakage situation.
It should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
