Description
Technical field:
The utility model relates in a kind of hole and to swash electric adjustable potential electrode apart from device, belongs to and measures 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) inadequately, 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 purpose of this utility model is to overcome the deficiency of prior art, and provides a kind of simple in structure, and is easy to use, swashs electric adjustable potential electrode in a kind of hole that is easy to safeguard apart from device.
Swashing electric adjustable potential electrode in a kind of hole of the present utility model 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) of mainly forming and can regulate the measurement pole span on the line (2), place the weight (6) of line (2) other end by hard PVC (3) and leads (4).
Principle of work of the present utility model 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 following hole, utilize probe to have function soft, that can regulate and fix four interelectrode distances; Soft is the 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 use immobilization with adhesive tape again by regulating around, folding; Measuring pole span can select for use between 0.2m～40m, and the signal that collects is strengthened.
Sheathed cable on the winch or reinforcement PVC cover cable (four-core) are connected socket attaching electrode attachment plug (water-tight type), indicate the corresponding relation of each electrode with cable 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 face of land writes down the sharp electric data of this point, to install toward transferring the distance of a measuring point by the selected test point distance of mission requirements then, test of stable back and record data, the down survey of a point of a point like this, 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 face of land, has finished in this hole just test.
Advantage of the present utility model is:
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 the 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 the immobilization with adhesive tape distance of two potential electrode (or change) again by the combination in twos of four measuring electrode; Measuring pole span can select for use between 0.2m～40m, by changing the distance between the potential electrode, the useful signal that measures is strengthened, thereby improved the sensitivity of test greatly, 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 suitable magnetic and the non-magnetic environment is applicable to and seeks sulfide metallic ore and copper mine.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Swashing electric adjustable potential electrode in a kind of hole of the present utility model 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 of mainly forming and can regulate the measurement pole span on the line 2, place the weight 6 of line 2 other ends by hard PVC (3) and leads (4).
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 for use 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 acquired signal is protected.
(2) utilize the conventional winch that is specifically designed to well logging, sheathed cable on the winch or reinforcement PVC cover cable (four-core) are connected socket attaching electrode attachment plug (water-tight type).
(3) starting winch will swash electric adjustable potential electrode when hanging the position stability that needs test to boring apart from device in the hole, the conventional induced polarization instrument that promptly is used in the face of land writes down the sharp electric data of this point.
(4) will install toward transferring the distance of a measuring point, also record data, the down survey of pointwise like this of stable back test by the selected test point distance of mission requirements then, directly measure at the bottom of the hole, in the test as when running into the not enough 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 face of land, has finished in this hole just test again.
Facts have proved that the utility model reaches designing requirement fully.
