Description
Technical Field
The utility model provides a device in the natural gas field, specifically speaking bury plastics natural gas line and seek the device.
Background
The development, the removal and the like of house buildings often occur at the periphery along the underground natural gas pipeline, and if construction units and operators do not know the accurate position of the underground natural gas pipeline, accidents of accidentally injuring the natural gas pipeline can occur, and social public safety is threatened. For preventing this kind of accident, usually adopt bury the underground along the natural gas pipeline or subaerial mode of installing the warning sign come the early warning, nevertheless because the specification, interval and the mounted position of warning sign can't be unified, and often by artificial destruction, consequently no matter be construction or natural gas maintenance personal overhaul pipeline, still can have the risk of burying the pipeline position with unable accurate judgement.
At present, in order to reduce the cost of metal pipelines and prevent corrosion and air leakage, plastic pipelines are generally used for conveying natural gas, and because the plastic pipelines are not conductive, a metal detector is difficult to detect the positions of the plastic pipelines, so that adverse effects are brought to the control of the trend of the pipelines and the avoidance of construction. Therefore, a device for searching for an underground plastic natural gas pipeline is urgently needed.
SUMMERY OF THE UTILITY MODEL
Bury plastics natural gas pipeline's position for accurate judgement, improve maintenance personal maintenance efficiency, reduce the emergence of natural gas pipeline damage accident, the utility model provides a bury plastics natural gas pipeline and seek device. The device solves the technical problem of searching for the buried plastic natural gas pipeline by a carrier signal generated by the conductive wire in the searching pipeline.
The utility model provides a scheme that technical problem adopted is:
each two sections of plastic natural gas conveying pipes are connected with the tee joint through hot melting to form a natural gas conveying pipeline. A vertical pipe is hot-melted on the upper part of the tee joint, the upper part of the vertical pipe is connected with a pipe well, the upper opening of the pipe well is arranged below the ground, and an electromagnetic wave generator is arranged on the upper part of the pipe well; an electromagnetic wave detector is arranged on the outer side of the plastic natural gas conveying pipe, and a probe is arranged on the detector through a detection rod. And conductive wires are penetrated in the pipe well, the vertical pipe and the plastic natural gas conveying pipe.
The utility model discloses utilize electromagnetic wave detector to survey the existence of conductive wire, judge the accurate position of plastics natural gas pipe, provide the safety guarantee for the construction, also create the condition for the natural gas line overhauls simultaneously, have safety, high efficiency and practice thrift the cost characteristics. The device is suitable for being used as a device for detecting the buried plastic natural gas pipe.

FIG. 1 is a schematic view of the present invention;
in the figure, 0 is an electromagnetic wave generator, 1 is a plastic natural gas conveying pipe, 2 is a tee joint, 3 is a pipe well, 4 is a conductive wire, 5 is a probe, and 6 is an electromagnetic wave detector.
Detailed Description
Each two sections of plastic natural gas conveying pipes 1 are connected with a tee joint 2 through hot melting to form a natural gas conveying pipeline.
A vertical pipe is hot-melted on the upper part of the tee joint, the upper part of the vertical pipe is connected with a pipeline well 3, the upper opening of the pipeline well is arranged below the ground, and an electromagnetic wave generator 0 is arranged on the upper part of the pipeline well;
an electromagnetic wave detector 6 is arranged on the outer side of the plastic natural gas conveying pipe, and a probe 5 is arranged on the detector through a detection rod.
And conductive wires 4 are penetrated in the pipe well, the vertical pipe and the plastic natural gas conveying pipe.
Use of:
when the device is used, the electromagnetic wave generator is used for transmitting electromagnetic waves to the conductive wire, the backpack electromagnetic wave sensor and the electromagnetic wave probe are used for detecting the electromagnetic waves and sensing the position of the conductive wire, and the position of the plastic natural gas transmission pipe can be sensed.
The technical principle is as follows:
when the conductive wire has electromagnetic waves, the electromagnetic wave detector and the probe can sense the existing position of the electromagnetic wave guide line, and the existing position and the trend of the plastic natural gas conveying pipe penetrating the conductive wire can be detected according to the position of the conductive wire, so that the management and the pipe arrangement surveying and mapping of the plastic natural gas conveying pipe are facilitated.
The electromagnetic wave is conducted in the form of a carrier wave in the conductive filament.
The innovation points are as follows: the plastic natural gas conveying pipe is internally penetrated with a conductive wire, an electromagnetic wave generator emits electromagnetic waves to the conductive wire, and an electromagnetic wave detector and a probe are used for detecting the position and the trend of the plastic pipeline provided with the conductive wire.
The method is characterized in that:
this device is through setting up the conducting wire in plastics natural gas conveying pipe, surveys the position of the plastics pipeline that is equipped with the conducting wire through electromagnetic wave detector, and is very convenient to look for plastics natural gas conveying pipe position, but also can the perception plastics natural gas conveying pipe move towards and the layout. The method has the characteristics of accurate detection result, safety, high efficiency and cost saving.
