Description
Technical field
The utility model relates to a kind of drilling electrodes based on physical prospecting electrical method cable, belong to drilling electrode field of tool.
Background technique
High-density electric in physical prospecting is mainly used in engineering geological investigation field, and measurement work is generally carried out in earth's surface,
By tens, in up to a hundred rodlike copper electrodes insertion soil, every electrode be grounded well, then by electrode to underground power with
Measurement, reaches exploration purpose.The prior art, high-density electric can also be applied to the interior measurement that drills, i.e., across hole resistivity CT measurement,
But how to power to subterranean body in drilling, there is presently no preferable solutions.
Across hole resistivity CT measurement is currently in the application study stage at home, it is non-can lava area using more,
Because that can be directly placed into drilling with water storage, physical prospecting cable in its drilling, powers and measure to underground by water coincidence.But expensive
State, Yunnan etc. can lava area, it is substantially anhydrous while also not storing water in drilling, then it is extremely tired to carry out across hole resistivity CT measurement
Difficulty, the method solved at present have 2 kinds：1, disposable cable is made, drilling is tamped after being put into drilling, is then surveyed
Amount.The method there are the problem of have：（1）, it is at high cost；（2）, drilling backfill closely knit difficulty, cause imperfect earth, influence to measure number
According to reliability.2, the absorbent articles such as sponge are bundled at the cable metal tap of electrical method, and drilling is put into after watering.The method
There are the problem of be：The objects such as sponge are not protected, and are easily damaged during being put into drilling, are caused imperfect earth.
I.e.：A kind of drilling electrode based on physical prospecting electrical method cable is now needed, can guarantee that electrode and hole wall can be carried out well
Contact, the accuracy rate of measurement is effectively ensured.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of drilling electrodes based on physical prospecting electrical method cable, can protect
Card electrode and hole wall can be carried out it is good contact, the accuracy rate of measurement is effectively ensured, can be with overcome the deficiencies in the prior art.
The technical solution of the utility model is：A kind of drilling electrode based on physical prospecting electrical method cable, it includes metal tube
Set is equipped with the through slot being easily installed at cable metal tap in metal pipe sleeve, is equipped with not on the side wall of metal pipe sleeve
Through-hole less than three is equipped with the elastic conductive device for pushing against drill hole inner wall in through-holes.
Above-mentioned elastic conductive device includes the metal spring that two different radiis are connected together, described two different radiis
Metal spring 4 in, the metal spring of small radii is mounted on through-hole, is equipped with strong absorptive in biggish metal spring
Water-absorbent material.
The prior art compares, and drilling electrode of the utility model based on physical prospecting electrical method cable, it includes metal pipe sleeve,
Metal pipe sleeve is equipped with the through slot being easily installed at cable metal tap, and no less than three are equipped on the side wall of metal pipe sleeve
A through-hole is equipped with the elastic conductive device for pushing against drill hole inner wall in through-holes；Elastic conductive device includes two differences
Radius is connected metal spring together, and in the metal spring of described two different radiis, the metal spring of small radii is mounted on
On through-hole, the water-absorbent material of strong absorptive is installed in biggish metal spring.Such structure, passes through elastic conductive device
Can guarantee electrode and hole wall can be carried out it is good contact, the accuracy rate of measurement is effectively ensured；Water-absorbent material is conducive to conduction.

Fig. 1 is the attachment structure schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the attachment structure schematic diagram of metal pipe sleeve.
Fig. 4 is the attachment structure schematic diagram of elastic conductive device.
Wherein, metal pipe sleeve 1；Through slot 2；Through-hole 3；Metal spring 4；Water-absorbent material 5.
Specific embodiment
For embodiment 1. as shown in Figure 1, a kind of drilling electrode based on physical prospecting electrical method cable, it includes metal pipe sleeve 1,
Metal pipe sleeve 1 is equipped with the through slot 2 being easily installed at cable metal tap, is equipped on the side wall of metal pipe sleeve 1 many
In three through-holes 3, the elastic conductive device for pushing against drill hole inner wall is installed in through-hole 3.The elastic conductive device
It is connected metal spring 4 together including two different radiis, in the metal spring 4 of described two different radiis, small radii
Metal spring 4 is mounted on through-hole 3, and the water-absorbent material 5 of strong absorptive is equipped in biggish metal spring 4.
