Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical resistivity meter technology, specifically a high-density electrical resistivity meter. Background Technology
[0002] Electrical resistivity tomography is a commonly used geophysical exploration method. High-density electrical resistivity tomography uses an electrode switching device to enable automatic electrode switching, avoiding the hassle of manual electrode movement. High-density electrical resistivity tomography can switch between multiple electrode movement modes, thereby collecting multiple sets of data based on various electrode movement methods and achieving more accurate detection.
[0003] When using existing technology, the connection between the metal sheet on the electrode box and the pit on the electrode is unstable, which can cause the electrode box to loosen or even fall off. This leads to unstable or even interrupted transmission of measurement data. The fixing effect of the spring is poor, which affects the measurement results of the entire high-density electrical resistivity method and cannot achieve a stable and high-strength fixing effect. At the same time, the disassembly of the electrodes in the existing electrical resistivity instrument is relatively cumbersome and cannot achieve rapid assembly, which affects the measurement efficiency. Utility Model Content
[0004] This invention provides a high-density electrical resistivity meter, which has the advantages of unstable electrode connection, easy loosening and inconvenient disassembly, in order to solve the problem of unstable connection between the metal sheet on the electrode box and the pit on the electrode, which can cause the electrode box to loosen or even fall off.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-density electrical resistivity meter, comprising a meter body, an electrode box at one end of the meter body, a support assembly on the outer side of the electrode box, a connection socket at the bottom of the electrode box, a limiting groove on the inner sidewall of the connection socket, an electrode post on the inner bottom wall of the connection socket, the electrode post being electrically connected to the electrode box, an electrode rod inserted into the inner wall of the connection socket, a limiting ring on the outer side of the electrode rod, a conductive assembly in the middle of the electrode rod, and a connection assembly in the middle of the electrode post.
[0006] As a preferred embodiment of this utility model, the support assembly includes a connecting frame and a plug rod. The connecting frame is sleeved on the outside of the electrode box, and the plug rod passes through the connecting frame.
[0007] As a preferred embodiment of the present invention, the conductive component includes an electrode socket, a conductive sheet, and a spring. The electrode socket is located at one end of the electrode rod, the conductive sheet is disposed on the inner wall of the electrode socket, one end of the spring is fixedly installed on the outer side of the conductive sheet, and the other end of the spring is fixedly installed on the inner wall of the electrode socket.
[0008] As a preferred embodiment of this utility model, the connecting component includes a cavity and a pressure post. The cavity is opened at one end of the electrode post, and the pressure post is movably installed on the inner wall of the cavity.
[0009] As a preferred embodiment of this utility model, the connecting assembly further includes a telescopic rod, which is movably installed in the middle of the electrode column. The inner sidewall of the cavity is provided with a movable hole adapted to the telescopic rod, and the telescopic rod is located above the pressure column.
[0010] As a preferred embodiment of this utility model, the top end of the pressure column is chamfered, and one end of the telescopic rod is chamfered.
[0011] As a preferred embodiment of this utility model, the initial state of the spring is its original length, and the top end of the conductive sheet is chamfered.
[0012] Compared with the prior art, the present invention provides a high-density electrical resistivity meter, which has the following beneficial effects:
[0013] In this high-density electrical resistivity meter, the electrode rod is inserted along the inner wall of the connection socket. At this time, one end of the electrode rod is inserted into the inner wall of the electrode socket. When the limiting ring on the outside of the electrode rod coincides with the limiting groove, the electrode rod is rotated to lock the limiting ring and the limiting groove, thereby ensuring that the electrode rod will not fall off. The pressure column contacts the bottom of the electrode socket and moves upward along the inner wall of the cavity. At this time, the top of the pressure column will squeeze the telescopic rod, thereby causing the telescopic rod to expand outward along the circular hole on the outside of the electrode rod. At this time, the telescopic rod will squeeze the conductive sheet, ensuring the electrical connection stability of the electrode rod. Attached Figure Description

[0021] Specifically, the support components include a connecting frame 2 and a plug rod 4. The connecting frame 2 is sleeved on the outside of the electrode box 3, and the plug rod 4 is set through the connecting frame 2.
[0022] In this embodiment, a support component is provided to support and fix the electrode box 3, thereby ensuring the stability of the electrode box 3. The insertion rod 4 can be inserted and fixed to the ground.
[0023] Specifically, the conductive component includes an electrode socket 9, a conductive sheet 10, and a spring 11. The electrode socket 9 is located at one end of the electrode rod 5. The conductive sheet 10 is disposed on the inner side wall of the electrode socket 9. One end of the spring 11 is fixedly installed on the outer side of the conductive sheet 10, and the other end of the spring 11 is fixedly installed on the inner side wall of the electrode socket 9.
[0024] In this embodiment, an electrode insertion hole 9 is provided for insertion into the electrode post 8, thereby connecting the electrode rod 5 and the electrode post 8. The conductive sheet 10 is used to contact the telescopic rod 13 provided on the outside of the electrode post 8, thereby achieving an electrical connection between the electrode rod 5 and the electrode box 3. The spring 11 serves to connect and press the conductive sheet 10, thereby ensuring that the electrode post 8 and the electrode rod 5 are in close contact.
[0025] Specifically, the connecting assembly includes a cavity 14 and a pressure post 12. The cavity 14 is opened at one end of the electrode post 8, and the pressure post 12 is movably installed on the inner wall of the cavity 14.
[0026] In this embodiment, a cavity 14 is provided for installing the pressure column 12, and the pressure column 12 can move within the inner wall of the cavity 14, thereby squeezing the telescopic rod 13 to make contact with the conductive sheet 10.
[0027] Specifically, the connecting assembly also includes a telescopic rod 13, which is movably installed in the middle of the electrode post 8. The inner wall of the cavity 14 is provided with a movable hole that is adapted to the telescopic rod 13, and the telescopic rod 13 is located above the pressure post 12.
[0028] In this embodiment, a telescopic rod 13 is provided to contact the conductive sheet 10 provided on the inner wall of the electrode socket 9, thereby realizing the connection between the electrode post 8 and the electrode rod 5.
[0029] Specifically, the top of the pressure column 12 is chamfered, and one end of the telescopic rod 13 is chamfered.
[0030] In this embodiment, chamfers are made on the end faces of the pressing column 12 and the telescopic rod 13 to squeeze the telescopic rod 13, causing the telescopic rod 13 to expand outward and squeeze the conductive sheet 10, thus ensuring the electrical connection between the electrode column 8 and the electrode rod 5.
[0031] Specifically, the spring 11 is initially in its original length state, and the top of the conductive sheet 10 is chamfered.
[0032] In this embodiment, a spring 11 is used to install the conductive sheet 10, and the spring 11 generates a reverse force under the compression of the conductive sheet 10 to press the conductive sheet 10 against the telescopic rod 13, ensuring close contact between the conductive sheet 10 and the telescopic rod 13.
[0033] The working principle and usage process of this utility model are as follows: During use, the electrode rod 5 is inserted along the inner wall of the connecting hole 6. At this time, one end of the electrode post 8 is inserted into the inner wall of the electrode hole 9. When the limiting ring 15 on the outer side of the electrode rod 5 coincides with the limiting groove 7, the electrode rod 5 is rotated to engage the limiting ring 15 with the limiting groove 7. During the insertion of the electrode rod 5, the pressing post 12 on the inner wall of the electrode post 8 contacts the bottom of the electrode hole 9, and the pressing post 12 moves upward along the inner wall of the cavity 14. At this time, the top of the pressing post 12 will press against the telescopic rod 13. This causes the telescopic rod 13 to expand outward along the circular hole on the outside of the electrode post 8. At this time, the telescopic rod 13 will squeeze the conductive sheet 10. The spring 11 generates a reverse force under the compression of the conductive sheet 10 to press the conductive sheet 10 against the telescopic rod 13, ensuring tight contact between the conductive sheet 10 and the telescopic rod 13. This ensures a stable connection between the electrode rod 5 and the electrode box 3. After the electrode rod 5 is connected, the insertion rod 4 is inserted into the ground to lift the electrode box 3, thereby preventing the electrode box 3 from getting damp or causing the electrode rod 5 to shake, which would affect the measurement accuracy of the electrical resistivity meter body 1.
