A multifunctional electrode conversion box that can be used for various exploration methods

Abstract

The invention discloses a multifunctional electrode conversion box for multiple exploration methods, and the conversion box consists of a locking drive module, a synchronous sensor module, a multipath current input control module, and a closed metal housing. The synchronous sensor module achieves the synchronization of relay absorption and data collection, and reduces the time difference generated by instruction sending and relay absorption, thereby guaranteeing the instantaneity and reliability of data. The multipath current input control module achieves different arrangement modes of electrodes through the control of the on / off of relays on different circuits, and meets the exploration demands of different exploration methods. The closed metal housing aims at preventing vapor and dust in complex underground projects (tunnel, coal and water conservancy) from affecting an instrument, and protects the instrument.

[0002] With the continuous development of the economy, the continuous advancement of science and technology, and the continuous development of underground projects such as tunnels, coal mines, and water conservancy projects, geological disasters such as water and mud inrush and landslides have occurred, causing casualties, economic losses, and environmental damage. Therefore, in order to prevent The occurrence of geological disasters during the construction period requires advanced geological prediction during the construction period. At present, the main prediction methods and instruments include conventional resistivity method, high-density resistivity method, induced polarization method, transient electromagnetic method, geological radar, TSP , TGP, and infrared water detection, etc. Among them, the conventional resistivity method, high-density resistivity method, and excited polarization method all need to deploy electrodes for detection. At present, the existing instruments can realize the above methods, but the difference between each method When switching, the electrodes need to be rearranged, which makes the detection time too long and hinders the construction of tunnels, coal mines, water conservancy and other underground projects. Therefore, in order to realize the switching between electrodes of several detection methods and reduce the detection time, it is necessary to design a An instrument that realizes the mutual conversion of electrodes in several detection methods to meet engineering applications
