Abstract
The utility model relates to accurate positioning equipment for a pipeline inspection gauge (PIG). The accurate positioning equipment for the PIG comprises a signal transmitting device and mobile receiving equipment, wherein the signal transmitting device is arranged on an intermediate shaft of the PIG; and a pipeline is provided with a plurality of fixed monitoring equipment along the line. The accurate positioning equipment for the PIG is capable of rapidly and accurately positioning the PIG and reducing excavation area, thereby, construction cost is saved, labor strength is reduced, and the working efficiency is increased.
Description
Technical field
The utility model relates to the accurate positioning equipment of a kind of pipeline PIG.
Background technique
Existing pipeline pig is divided into two kinds: 1, pipeline has no positioning equipment; But 2, have certain locating function positioning error big, the operation conditions of pipeline pig in pipeline can not be understood timely, when spheroid occurs damaging a large amount of gas leakage; Can not in time find; When pipeline pressure test, pigging run into pipeline card ball phenomenon,, cause a large amount of human and material resources resources of waste and incur loss through delay the duration owing to there is not accurate pig location facilities to cause the position of ball to be difficult to find.
Summary of the invention
The purpose of the utility model is to provide a kind of accurate positioning equipment of pipeline pig of accurate targeted duct PIG fast.
The technological scheme of the utility model is:
The accurate positioning equipment of pipeline pig; Comprise sender unit and mobile receiving device; Sender unit is installed on the pipeline pig jack shaft; Sender unit 1 adopts the mixing current signal way of output of combination frequency, can launch the alternating signal of three kinds of different frequencies simultaneously, and pipeline is provided with the plurality of fixed watch-dog along the line.
Said sender unit comprises: transmitter fixed system, AC signal generation systems, alternating signal regulator control system, autonomous power supply system, self-checking system.
Said fixedly watch-dog comprises: magnetic field induction system, stray electrical current filtration system, signal amplify regulating system, data presentation system, stocking system.
Before pipeline pig puts into pipeline; It is along the line that the plurality of fixed watch-dog is arranged on pipeline; The pipeline pig that sender unit is installed gets into pipeline through stationary monitoring equipment the time; The alternating signal of stationary monitoring equipment meeting automatic reception sender unit, the buried depth of testing conduit also writes down pipeline pig through the out-of-date time; When problem such as card ball etc. appears in pipeline pig in pipeline, according to the record of stationary monitoring equipment, seek out pipeline pig Position Approximate.The site operation personnel can hold mobile receiving device and accurately locate at the Position Approximate that pipeline pig exists, and the buried depth of test place pipeline.
The utility model is targeted duct pig fast, accurately, reduces excavation area, has practiced thrift construction cost, has reduced labor intensity, has improved working efficiency.

Embodiment
The accurate positioning equipment of pipeline pig; Comprise sender unit 1 and mobile receiving device 3; Sender unit 1 is installed on the pipeline pig4 jack shaft, and sender unit 1 adopts the mixing current signal way of output of combination frequency, can launch the alternating signal of three kinds of different frequencies simultaneously.
Pipeline is provided with plurality of fixed watch-dog 2 along the line; Fixedly the alternating signal of the fixed frequency sent of the magnetic coil cutoff signal transmitter 1 of watch-dog 2 through the magnetic field induction system produces induction current; Induction current is selected the induction current of transmitter fixed frequency through the stray electrical current filtration system; Electric current after the screening amplifies signal conversion through signal amplifier, shows through digital readout system at last and passes through storage system stores.
Should be noted that at last: above embodiment only in order to the explanation the utility model technological scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the embodiment of the utility model perhaps is equal to replacement to the part technical characteristics; And not breaking away from the spirit of the utility model technological scheme, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
