Abstract

The invention discloses a device for IP measurement of adjustable electrode distance in an SDJ-KT hole, belonging to the technical field of measurement engineering. The device comprises a connection wire (2) provided with an inner four-core copper insulation wire, an outer reinforced tensile-resistant soft PVC (polyvinyl chloride) sleeve and a built-in tensile-resistant nylon wire, a four-core socket sleeve (1) provided with a four-core socket and arranged on one end of the connection wire (2), four electrodes (5) consisting of hard PVC (3) and lead strips (4) and arranged on the connection wire (2), and a heavy hammer (6) on the other end of the connection wire (2). The device has a simple structure, is convenient in use and maintenance, and can collect the actual data. The device can beused for measuring the electrode distance within a range from 0.2 m to 40 m due to the flexible structure and adjustability of the device and can strengthen detected effective signals, so that the device can be used in the weak-signal environment to find blind ores beside or under a mine, thereby improving the ore-finding rate. In addition, the device is suitable for IP measurement in a hole underground well manner in magnetic and non-magnetic environments, and is suitable for finding sulfide metal mines and copper mines.

Description

Technical field: [0001] The invention relates to an SDJ-KT type hole in-hole IP adjustable measuring electrode distance device, which belongs to the technical field of measurement engineering. Background technique: [0002] In the prior art, in the ground-hole measurement by the induced polarization method, electrodes with a receiving distance of 5m to 20m are mostly used. In operations with a deep hole depth> 200m, the collected data signal is not strong enough (relative to the error), and the receiving electrode The distance is not adjustable, and the electrode material is usually made of copper sheet, which is easy to cause polarization instability. Summary of the invention: [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a SDJ-KT type hole in-hole IP adjustable measuring electrode distance device with simple structure, convenient use and easy maintenance. [0004] The SDJ-KT type hole in-hole IP adjustable measuring...
