Technical Field
[0001] This utility model relates to the field of electrode rod technology, and in particular to an electrode rod device for geophysical exploration electrical methods. Background Technology
[0002] In the field of geophysical exploration, electrical resistivity tomography (ERT) is a commonly used exploration method. It infers underground geological structure by measuring changes in underground electrical parameters. It is of great significance for mineral resource exploration, geological disaster prediction, and environmental monitoring. In the process of ERT, the electrode rod is one of the key pieces of equipment, which undertakes important tasks such as injecting current into the ground and measuring potential difference. Its performance and ease of use directly affect the accuracy of exploration results and operational efficiency.
[0003] Traditional electrode rod devices have some shortcomings in design and use. The problem of wire storage has always been a problem for operators. After the survey is completed, the wires are often piled up in a mess. They are not only easy to get tangled and knotted, making it difficult to untangle them quickly when used again, but they are also easily damaged by wear and tear during transport, affecting the service life of the wires and the quality of signal transmission. This not only increases the labor intensity of the operators, but may also lead to inaccurate survey data due to wire problems, affecting the reliability of the survey results.
[0004] To address the problems associated with traditional electrode rod devices and improve the efficiency and quality of electrical resistivity tomography (EDT) operations in geophysical exploration, it is necessary to develop a new type of electrode rod device that optimizes the conductor storage structure to provide more convenient, efficient, and reliable equipment support for exploration operations. Utility Model Content
[0005] In view of this, the present invention aims to provide an electrode rod device for geophysical exploration electrical resistivity tomography, in order to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.
[0006] The technical solution of this utility model embodiment is implemented as follows: An electrode rod device for geophysical exploration electrical resistivity tomography includes an electrode rod body. A clamp is installed on an annular groove on the side of the electrode rod body by a fixing component. A wire is electrically connected to the top of the electrode rod body, and a connector is fixed at the end of the wire away from the electrode rod body. An intermediate plate is welded to the side wall of the clamp, and a winding roller is fixed to the side wall of the intermediate plate. The winding roller has a notch adapted to the wire.
[0007] In some embodiments, the fastener includes a nut and a bolt, and the side wall of the clamp has a socket adapted to the bolt. After the bolt is inserted into the socket, it is threadedly connected to the nut.
[0008] In some embodiments, the winding roller includes a winding column, a first limiting plate, and a second limiting plate. The second limiting plate is welded to the side wall of the intermediate plate, the winding column is welded to the side of the second limiting plate, and the first limiting plate is welded to the side wall of the winding column.
[0009] In some embodiments, a conical block is fixed to the bottom of the electrode rod body by a mounting component.
[0010] In some embodiments, the mounting component includes a threaded post and a threaded groove, the threaded post being integrally formed at the bottom of the electrode rod body, and the threaded groove being formed at the top of the conical block.
[0011] In some embodiments, a connecting plate is welded to the side wall of the clamp, and a pin is welded to the bottom of the connecting plate.
[0012] In some embodiments, a plurality of the notches are formed around a surface of the limiting plate.
[0013] In some embodiments, the threaded post and the threaded groove are threaded together.
[0014] The present invention has the following advantages due to the adoption of the above technical solution:
[0015] 1. An electrode rod device for electrical resistivity tomography (EDT) in geophysical exploration, comprising a winding roller on the side wall of a clamp, allowing the wire to be manually wound onto the winding rod after exploration, achieving effective wire storage and preventing the wire from becoming tangled. This not only facilitates carrying but also provides good protection for the wire, preventing damage during transport and extending its service life. Simultaneously, notches on the winding roller securely fasten the wound wire, further ensuring it does not unravel during transport, improving ease of use and reliability.
[0016] 2. An electrode rod device for electrical resistivity tomography (EDT) in geophysical exploration, wherein a clamp is fixed to an annular groove on the side of the electrode rod body via fasteners (nuts and bolts). The installation method is flexible, allowing for easy adjustment of the clamp's position according to actual needs. The clamp has a certain degree of elasticity, enabling better contact with the annular groove. Combined with the threaded connection of the bolts and nuts, the fixation between the clamp and the annular groove is more secure, thus ensuring the stability of the entire device structure and facilitating the normal operation of the electrode rod during exploration.
[0017] 3. An electrode rod device for electrical resistivity tomography (EDT) in geophysical exploration, wherein the bottom of the electrode rod body is threadedly connected to a conical block via a threaded post and a threaded groove. The conical block enhances the electrode rod body's penetration capability into the ground, allowing the electrode rod to be inserted into the designated underground location more easily and quickly, thus improving the efficiency of exploration operations. Furthermore, a pin is welded to the bottom of the connecting plate welded to the side wall of the clamp. When the pin follows the electrode rod body into the ground, it provides auxiliary support to the electrode rod body, enhancing the stability of the electrode rod during underground installation and reducing the possibility of tilting or displacement of the electrode rod due to external factors (such as wind, soil loosening, etc.), ensuring the accuracy and reliability of exploration data.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0028] like Figure 1-4 As shown, an electrode rod device for geophysical exploration electrical resistivity tomography includes an electrode rod body 1. A clamp 17 is installed on an annular groove 11 on the side of the electrode rod body 1 by a fixing component. A wire 4 is electrically connected to the top of the electrode rod body 1, and a connector 3 is fixed at the end of the wire 4 away from the electrode rod body 1. An intermediate plate 13 is welded to the side wall of the clamp 17, and a winding roller is fixed to the side wall of the intermediate plate 13. The winding roller has a notch 12 that is compatible with the wire 4.
[0029] When an exploration is required, first insert the electrode rod body 1 into the ground, connect the connector 3 to the exploration instrument, and use the electrode rod body 1 to conduct the exploration. After the exploration is completed, disconnect the connector 3 from the instrument, and manually wind the wire 4 onto the winding roller to protect the wire 4. After the wire 4 is wound an appropriate number of times, lock the outer wall of the wire 4 and the notch 12 to ensure that the wire 4 will not come apart during the carrying process.
[0030] In geophysical exploration electrical resistivity tomography (EPT) operations, the arrangement and spacing of the electrode rods 1 are first determined based on the exploration task and the characteristics of the target area. They are then inserted into the ground in a specific arrangement to form an electrode array, and the appropriate insertion depth is determined. Next, the top connector 3 of the electrode rod 1 is connected to the exploration instrument, ensuring that the connector 3 is firmly in contact. Subsequently, the instrument is started, current is injected into the power supply electrodes to form an electric field, and the potential difference and other information are measured by the electrodes and transmitted back to the instrument. After the instrument filters and denoises the collected data, it uses software algorithms to calculate the resistivity value and draw the result map. Geologists then use this data, combined with geological background information, to interpret and analyze the underground geological structure.
[0031] The fastener includes a nut 15 and a bolt 16. The side wall of the clamp 17 has a socket adapted to the bolt 16. After the bolt 16 is inserted into the socket, it is threadedly connected to the nut 15.
[0032] The clamp 17 has a certain degree of elasticity. After the clamp 17 and the annular groove 11 on the electrode rod body 1 are enclosed, the bolts 16 are inserted into the two sets of holes opened on the clamp 17 in sequence, and the nut 15 and the bolts 16 are threaded together, so that the clamp 17 and the annular groove 11 can be fixed.
[0033] The winding roller includes a winding column 5, a first limiting plate 10 and a second limiting plate 14. The second limiting plate 14 is welded to the side wall of the intermediate plate 13, and the winding column 5 is welded to the side of the second limiting plate 14. The first limiting plate 10 is welded to the side wall of the winding column 5. Multiple sets of notches 12 are opened around the surface of the first limiting plate 10.
[0034] The winding post 5 can be used to wind the wire 4. The limiting plate 10 and the limiting plate 2 14 limit the wire 4 to prevent it from coming off the winding post 5 during the winding process.
[0035] The bottom of the electrode rod body 1 is fixed with a conical block 2 by an installation component. The installation component includes a threaded post 6 and a threaded groove 7. The threaded post 6 is integrally formed at the bottom of the electrode rod body 1, and the threaded groove 7 is opened at the top of the conical block 2. The threaded post 6 and the threaded groove 7 are threadedly connected.
[0036] When the threaded groove 7 on the conical block 2 is threadedly connected to the threaded post 6 at the bottom of the electrode rod body 1, the conical block 2 can be used to improve the puncture capability during the process of inserting the electrode rod body 1 into the underground.
[0037] The clamp 17 has a connecting plate 9 welded to its side wall, and a pin 8 is welded to the bottom of the connecting plate 9.
[0038] When the insertion pin 8 is inserted into the ground along with the electrode rod body 1, the insertion pin 8 provides auxiliary support for the electrode rod body 1.
[0039] In this embodiment: In geophysical exploration electrical resistivity tomography, the arrangement position and spacing of the electrode rod body 1 are first determined according to the exploration task and the characteristics of the target area. The electrode rods are then inserted into the ground in a specific arrangement to form an electrode array, and a suitable insertion depth is determined. The threaded post 6 at the bottom of the electrode rod body 1 is threadedly connected to the threaded groove 7 at the top of the conical block 2. The conical block 2 is used to improve the piercing ability of the electrode rod body 1 when inserted into the ground. A clamp 17 with a certain elasticity is placed around the annular groove 11 on the side of the electrode rod body 1. Bolts 16 are inserted sequentially into the two sets of insertion holes on the clamp 17. Nuts 15 are then threadedly connected to bolts 16, thereby fixing the clamp 17 to the annular groove 11. When the insertion pin 8 follows the electrode rod body 1 into the ground, it can provide auxiliary support for the electrode rod body 1. Inserting the electrode rod body 1 into the ground indicates… After positioning, connect the connector 3 at the top of the electrode rod body 1 to the exploration instrument, ensuring that the connector 3 is secure and makes good contact. Start the exploration instrument, inject current into the power supply electrode to form an electric field, measure the potential difference and other information of the measuring electrode and transmit it back to the instrument. After the instrument filters and denoises the collected data, it uses software algorithms to calculate the resistivity value and draw the result map. Geologists interpret and analyze the underground geological structure based on this and the geological background data. After the exploration is completed, disconnect the connector 3 from the instrument and manually wind the wire 4 around the winding column 5. The limiting plate 10 and the limiting plate 2 14 limit the wire 4 to prevent it from coming off the winding column 5 during the winding process. After the wire 4 is wound an appropriate number of times, lock the outer wall of the wire 4 and the notch 12 to ensure that the wire 4 will not come loose during the carrying process.
