Drill the resistance parameter of boring underground medium around.But, in practice, in hole, in terms of power supply, encounter a difficult problem, especially
When running into the boring of small-bore, in the case of ensureing that current electrode contacts with hole wall closely, current electrode moves up and down and can compare
More difficult, often it is stuck among boring；Although reduce electrode diameter to can ensure that electrode moves up and down conveniently, but electrode and hole
Wall contact area is greatly reduced, and causes poor effect of powering.
Utility model content
For the problems referred to above, this utility model provides a kind of diameter little and can lift well ground unidirectional current freely in boring
Current electrode in the hole of method.
To this end, the technical solution of the utility model is as follows:
Current electrode in the hole of a kind of DC borehole-ground method, including: hollow and the insulating sleeve of upper end open, is arranged on
Electric magnet in this insulating sleeve, symmetry be hinged on insulating sleeve outer wall two conduction page plates, be arranged on each described conduction
Supporting spring and being arranged on the external electricity at described insulating sleeve upper end open between page plate lower end and insulating sleeve outer wall
Cable four core interface, described electric magnet and conduction page plate pass through electromagnet power supply connecting line and power supply connecting line respectively with described
External cable four core interface connects, after the installation direction of described electric magnet makes the energising of this electric magnet, and the lower end of two conduction page plates
To near the direction of insulating sleeve Guan Bi under the effect of electromagnetic field.
The top of described insulating sleeve is cone, and bottom is cylindrical, and jointed shaft is passed through in the upper end of described conduction page plate
It is hinged on described cone and cylindrical intersection.
Described electric magnet is solenoid electromagnet；Described solenoid electromagnet is in the bottom of insulating sleeve from top to bottom
Being arranged with 3 in parallel, 3 solenoid electromagnets are connected in series.
Current electrode in the hole of the DC borehole-ground method that the utility model discloses a kind of flexible reducing, arrives at electrode
During the purpose degree of depth, make conduction page plate contact with hole wall by support spring and fix, and then power to underground, measure；When
Need when other degree of depth are powered, by making conduction page plate overcome the elastic force of support spring to regain to electric magnet energising, convenient
The lifting of electrode.This electrode improves contact conditions, improves power supply effect, and can the external diameter of Autonomous Control current electrode, make
It promotes and declines very convenient, is difficult to drilled blocking.

Detailed description of the invention
With specific embodiment, structure of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, in the hole of DC borehole-ground method of the present utility model, current electrode includes: hollow and upper end
The insulating sleeve 5 of opening, the electric magnet 1 being arranged in insulating sleeve 5, symmetry are hinged on two conductions on insulating sleeve 5 outer wall
Page plate 2, the support spring 3 being arranged between each conduction page plate 2 lower end and insulating sleeve 5 outer wall and be arranged on described insulation
External cable four core interface 6 at sleeve 5 upper end open, described electric magnet 1 and conduction page plate 2 are respectively by electromagnet power supply even
Wiring 9 and power supply connecting line 8 are connected with b, c and a on described external cable four core interface 6, d binding post, and pass through
External cable four core interface 6 is connected with external power source.Seeing Fig. 3, in Fig. 1, the embodiment shown in 2, a, d binding post is jack per line
, i.e. they are simultaneously connected with the positive pole of high-voltage suppling power, or are simultaneously connected with the negative pole of high-voltage suppling power, for well ground
The measurement of DC electrical method.After the installation direction of described electric magnet 1 makes the energising of this electric magnet 1, the lower end of two conduction page plates 2 is at electricity
To near the direction of insulating sleeve 5 Guan Bi under the effect in magnetic field.
The top of described insulating sleeve 5 is cone, and bottom is cylindrical, and the upper end of conduction page plate 2 is cut with scissors by jointed shaft 4
It is connected on described cone and cylindrical intersection, the i.e. shoulder of insulating sleeve 5.
Described electric magnet 1 can be solenoid electromagnet.Described solenoid electromagnet can arrange 2 or multiple,
For example, it is possible to as depicted in figs. 1 and 2, it is arranged with 3 from top to bottom in parallel in the bottom of insulating sleeve 5,3 solenoid type electricity
Magnet is connected in series.It addition, for the magnetic improving electric magnet, it is also possible to put into iron core in solenoid, in this case,
Number can be set according to what practical situation determined electric magnet.
The using method of above-mentioned current electrode is as follows:
(1) measure preparation: the external cable four core interface first with electrode tip is connected with service cable, and give electricity
Magnet is energized, and is regained, as shown in Figure 2 by electrode both sides conduction page plate.
(2) formally measure: electrode is transferred to foot of hole, starts bottom-up lifting electrode, when arriving target depth
Time, utilize ground controller that the power-off of electric magnet, conduction page plate are opened under the elastic force supporting spring promotes, now led
Electricity page plate is in close contact with borehole wall 7, as it is shown in figure 1, then start to power to underground.When needing transformed depth, by electromagnetism
Tie Tong electricity, attracts conduction page plate to regain, makes electrode diameter diminish, can carry out promoting, declining.
