Multi-circuit electrode conversion head of electric depth measuring instrument

Technical Field

The utility model belongs to the technical field of the engineering exploration technique and specifically relates to a multicircuit electrode conversion head of deep appearance of electricity is related to.

Background

The resistivity method is one of geophysical prospecting methods, is continuously improved and perfected, is widely applied to various fields, uses special instruments and equipment based on the differences of the conductivity, the electrochemical activity (induced polarization property), the dielectricity and the magnetic conductivity of rocks and ores as materials, observes and researches the change and the distribution rule of a physical field around a crust, and further achieves the aim of solving the geological problem.

The working principle of resistivity method is that two or two groups of iron power supply electrodes A, B are driven into the ground, a transmitter is used to supply power to the ground, a stable current field is established underground, the instrument is used to observe the intensity of the power supply current I, then two or two groups of copper measuring electrodes M, N are driven into the ground, the potential difference delta V between the two electrodes is observed M, N, and the formula is adopted

The apparent resistivity value ρ s (unit: Ω m) at the interpolar midpoint was calculated at M, N.

The resistivity method can be further divided into a resistivity sounding method (abbreviated as an electrical sounding method) and a resistivity profile method according to an electrode arrangement mode and a working method.

The electric depth measurement method is to fix the electrode distance for measurement, change the electrode distance for power supply from small to large, and is used for studying the vertical distribution of different conductive geologic bodies under the measurement point and the measurement area from shallow to deep. The electrical sounding method is divided into symmetrical quadrupole sounding, dipole sounding, tripolar sounding, annular sounding, and pentapolar longitudinal axis sounding according to different electrode arrangement modes.

The electric section method is to make the electrode distance between the power supply electrode and the measuring electrode constant, and the whole device moves towards one direction along the measuring line to observe on different measuring points. Under the condition of the same exploration depth, the rock stratum and the structure condition along the measuring line are known, and the related geological problems are solved.

When the resistivity method is used for exploration, a multi-core cable is sometimes used, sub-lines separated from the multi-core cable are connected with electrodes, and only four joints are needed to be used for measuring one data point, wherein the four joints are respectively used as A, B, M, N. However, to complete the work of one measuring point, data of a plurality of transmitting polar distances AB and receiving polar distances MN need to be measured, so that A, B, M, N positions need to be frequently moved, joints with different numbers need to be selected from a plurality of wire ends, the time is long, and the work is very complicated.
