The invention discloses a signal receiver for natural electric field detection. The signal receiver comprises a detection probe I and a detection connector II, wherein the detection probe I comprises a detection rod 1 and a detection rod joint 2; and the detection connector II connected with a detection cable 5 comprises a detection connector 3 and a signal receiving circuit 4. The signal receiver is used for receiving a characteristic signal which is generated when a natural electric field is diffused in the stratum and encounters a special geologic body, and the natural electric field signal is received by the detection rod 1, is conducted to the signal receiving circuit 4 in the detection connector 3 through the detection rod joint 2, is regulated by the signal receiving circuit 4 and then is transmitted to a signal collecting device through the detection cable 5. The inserting operation of the detection probe I and the detection connector II is simple and convenient, the connection is firm and reliable, and the connection state and the signal transmission property can be detected, so that the reliability and precision of signal detection of the natural electric field can be ensured, and the special environment requirements for geological prospecting operation on the field are met.
Description
technical field [0001] The patent of the present invention belongs to the special detection device supporting the field of geological and geophysical prospecting instruments, especially related to the detection of natural electric field [0002] Use a signal receiver. Background technique [0003] In the fields of geophysical detection, mining geological disaster detection and groundwater exploration, in order to study and analyze the geological structure of the stratum, find out the distribution of groundwater sources, underground mined-out areas and special geological bodies. Various detection methods and instruments are widely used, such as geological radar, electrical detection, very low frequency detection methods and natural electric field detection methods. Among them, the natural electric field detection method has the advantages of high detection efficiency, continuous scanning, and low cost. Compared with other geophysical prospecting methods, it has the advantage...
