Abstract
The utility model discloses a mobile device in drilling of direct current electric method exploring electrode, including the wire, the interface, the PE pipeline, the hoop, a spring, measuring electrode MN and head, the hoop is connected on the PE pipe after welding with the spring, measuring electrode M and N are connected with detecting device through the wire in pipeline inside portion, be connected with strutting arrangement at the outside aperture through the junction of pipeline, owing to there is metal spring to support, can guarantee through spring and hoop transmission electric current between exploring electrode and the drill hole wall at the in -process that advances, and because the elastic reaction of spring, still can forward back after meetting the adjustment by oneself that to take place to deform when rubble or other factors block, not influenced by the pore wall, the head is globular pattern, can make the head adjust precedingly by oneself and then can not be motionless by calorie owner. The afterbody has the interface conveniently to carry, and installation is at any time lifted off.
Description
Technical field
This utility model belongs to tunnel DC electrical method boring forward probe application, relates to a kind of DC electrical method bore detecting mobile device.
Background technology
Current emerging a kind of DC electrical method bore detecting technology, arranges at one, rear, tunnel infinite point and receives electrode, arrange current electrode at face, and hole at front of tunnel heading, be arranged in hole by detection electrode.Current electrode feeds unidirectional current in the total space and sets up an artificial electric field, and its equipotential plane is exactly the sphere with current electrode as the centre of sphere, by the potential difference received between electrode measurement equipotential plane of certain intervals in hole.Often the mobile electrode that once detects, receives the potential difference produced between detection electrode successively, by this potential difference, can calculate the apparent resistivity of different depth position, thus judge whether front exists electric characteristic abnormality body.
But detect electrode in hole is disposed with many restrictions, if arranging in metal drill pipe, be highly prone to drilling rod affects reception, if plastic tube can play shield effectiveness the most again and not receive information, due to rough in boring in actual detection, easily produce blinding, if detected, electrode build is excessive can be stuck again, enter and do not go can't get out, cause detecting unsuccessfully, therefore it is badly in need of in a kind of hole arranging detection electrode assembly, neither impact receives electric current, can apply to again in reality, will not be stopped by interior blinding of holing.
Utility model content
In order to effectively receive, in boring, the current information that current electrode is sent, for existing technological deficiency, the emerging purpose of this practicality is to provide a kind of device based on DC electrical method bore detecting method, it is possible to solve the problem that detection electrode is difficult to arrange.
This utility model is to achieve these goals, the technical solution used is: detects electrode movement device in hole and includes wire, interface, PE pipeline, iron hoop, spring, measurement electrode MN and head, iron hoop is connected with spring on PE pipe, measure electrode M and N to be connected with detection device by wire at pipe interior, it is connected with support means at pipeline external, head is spherical to be connected with PE pipe, convenient advances, and afterbody has interface can conveniently dismantle and change.
As preferably, described spring is metal material and welds together with iron hoop, electrically conductive, iron hoop internal diameter is identical with PE pipe, iron hoop is maintained static on pipe and is having with PE pipe junction aperture can be connected with measurement electrode M and N respectively by PE pipe, and measurement electrode M and N can be made to receive the electric current of the wall of a borehole and be delivered at the detection device of tunnel work surface along wire.
As preferably, the spherical material of described head is identical with PE pipe with afterbody interface material, and internal connection is screw-like, compact will not fall down.
The utility model has the advantages that: this detection electrode movement device is fixing inside PE pipe, its material character does not interferes with Potential distribution in stratum, owing to there being metal spring to support, moving process can ensure detect between electrode and the wall of a borehole by spring and iron hoop transmission electric current, and due to the elastic reaction of spring, can deform upon when running into blinding or other factors stop and still can not affected by hole wall with forward-reverse after Row sum-equal matrix.This utility model head is spherical pattern, and head can be made to be advanced without by card main motionless from Row sum-equal matrix.Afterbody has interface to be convenient for carrying, and installs at any time and unloads.
Accompanying drawing explanation
Fig. 1 is mobile device schematic diagram in DC electrical method detection electrode boring.
Fig. 2 is supporting construction schematic diagram.
In figure, 1-interface, 2-PE manages, 3-support means, 3-1-iron hoop, 3-2-spring, 4-head, 5-wire, and 6-measures electrode M, 7-and measures electrode N.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As it can be seen, this utility model is from left to right followed successively by outside PE pipeline, wire, interface 1, internal PE pipeline 2, support means 3, measures electrode 6, measurement electrode 7 and head.Said two support means 3 is welded for iron hoop 3-1 and 4 metal spring 3-2, coupled together with internal measurement electrode M 6 and N 7 respectively by aperture with PE pipe 2 junction, not only can support pipeline but also electric current can be transmitted to measuring electrode along wire 5 until tunnel, due to metal spring 3-2 elastic reaction, can deform upon when running into blinding or other factors stop and still can not affected by hole wall with forward-reverse after Row sum-equal matrix.Described head 4 is spherical, and inside is threaded, both can prevent impurity from entering with locking device, and device can be facilitated again to advance.Described interface 1 can make device installing/dismounting, is convenient for carrying.
