Description
Technical field:
The present invention relates to swash in a kind of SDJ-KT type hole electric adjustable potential electrode apart from device, belong to and measure field of engineering technology.
Background technology:
Prior art is in hole, induced polarization method ground mode is measured, the electrodes that receive apart from 5m～20m that adopt receive more, in the operation of deep hole hole depth＞200m, the image data signal is strong (with respect to error) not, and receiving electrode is apart from non-adjustable, and electrode material copper sheet commonly used is made, and easily causes polarization unstable.
Summary of the invention:
The object of the invention is to overcome the deficiency of prior art, and provide a kind of simple in structure, easy to use, swash electric adjustable potential electrode in the SDJ-KT type hole that is easy to safeguard apart from device.
Swashing electric adjustable potential electrode in the SDJ-KT type of the present invention hole comprises apart from device: be copper four-core insulated wire, outer for reinforcement tension soft pvc sleeve pipe and be built-in with the line (2) of tension nylon wire in it, place the four-core jack sleeve (1) of the built-in four-core socket of line (2) one ends, place four electrodes (5) that mainly form and can regulate the measurement pole span by hard PVC (3) and leads (4) on the line (2), place the weight (6) of line (2) other end.
Principle of work of the present invention is:
The distance (r) certain in the aperture, ground or apart from the aperture arranged electrodes of A, and B cloth is made pole at infinity, and this device is put in the hole as potential electrode.Before the lower hole, utilize probe to have function soft, that can regulate and fix four interelectrode distances; Soft is that the long lead of electrode and connector lug and protective sleeve are soft, so also guaranteed to change between electrode and the electrode apart from the time, can by around, folding adjusting, use again immobilization with adhesive tape; Measuring pole span can select between 0.2m～40m, and the signal that collects is strengthened.
With the sheathed cable on the winch or cable (four-core) the connection socket attaching electrode attachment plug (sealed waterproof type) of reinforcement PVC cover, indicate the corresponding relation with cable of each electrode with the universal meter test.After preliminary work is carried out, hang the position that to boring need test and when stable with swashing electric adjustable potential electrode in the SDJ-KT type hole apart from device with winch lifting rope (comprise signal receive line), the induced polarization instrument that is used in the earth's surface records the sharp electric data of this point, then will install toward transferring the distance of a measuring point by the selected test point distance of mission requirements, test and record data after stable, the like this down survey of a point of a point, after measuring at the bottom of the hole, again by the up survey of the checkpoint point of setting apart from a point of a point at the bottom of the hole, when measuring the earth's surface, has finished in this hole just test.
The invention has the advantages that:
1, simple in structure, easy to use, be easy to safeguard that image data is true, be easy to measure the sharp electric signal in ground, the hole mode proving installation.
2, utilize this device to have function soft, that can regulate and fix four interelectrode distances, soft is long lead and the protective sleeve softness of electrode and connector lug, so also guaranteed to change between electrode and the electrode apart from the time, can be by regulating around, folding, use again the immobilization with adhesive tape distance of two potential electrode (or change by the in twos combination of four measuring electrode); Measuring pole span can select between 0.2m～40m, by changing the distance between the potential electrode, the useful signal that measures is strengthened, thereby improved greatly the sensitivity of test, can in the environment of weak signal, use, be easy to find that well takes up the shaft bottom blind ore, improve boring and sees the ore deposit rate.
3, ground well mode induced polarization measurement in the hole in applicable magnetic and the non-magnetic environment is applicable to seek sulfide metallic ore and copper mine.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
Swashing electric adjustable potential electrode in the SDJ-KT type of the present invention hole comprises apart from device: be copper four-core insulated wire, outer for reinforcement tension soft pvc sleeve pipe and be built-in with the line 2 of tension nylon wire in it, place the four-core jack sleeve 1 of the built-in four-core socket of line 2 one ends, place four electrodes 5 that mainly form and can regulate the measurement pole span by hard PVC (3) and leads (4) on the line 2, place the weight 6 of line 2 other ends.
The course of work is:
(1) determines the distance of several groups of MN potential electrode according to the degree of depth of the requirement of task and boring, utilize this device to have the fixedly distance of 5 at four measuring electrode of soft, the function that can regulate; Measuring pole span can select between 0.2m～40m and (by around, folding, use immobilization with adhesive tape, during the measurement of deep spread of electrodes is adjusted to 40m, the intensity of collection signal is protected.
(2) utilize the conventional winch that is specifically designed to well logging, with the sheathed cable on the winch or cable (four-core) the connection socket attaching electrode attachment plug (sealed waterproof type) of reinforcement PVC cover.
(3) start winch and just swash electric adjustable potential electrode in the SDJ-KT type hole and hang when needing the position stability of test to the boring apart from device, the conventional induced polarization instrument that namely is used in the earth's surface records the sharp electric data of this point.
(4) then will install toward transferring the distance of a measuring point by the selected test point distance of mission requirements, test and record data after stable, the like this down survey of pointwise, directly measure at the bottom of the hole, in the test as when running into the inadequate data of measuring accuracy, this device is pulled out, strengthen the distance between test electrode.
(5) after measuring at the bottom of the hole, up survey apart from pointwise at the bottom of the hole by the checkpoint point of setting, when measuring the earth's surface, has finished in this hole just test again.
Facts have proved that the present invention reaches designing requirement fully.
