Description

Technical Field

[0001] This invention belongs to the field of electromagnetic detection electrode technology, and particularly relates to a bottle-shaped split electrode structure and installation method on a graphene ceramic substrate. Background Technology

[0002] Electromagnetic methods are one of the important geophysical exploration methods for obtaining the distribution of underground electrical structures. Based on the skin effect of electromagnetic waves, this method calculates and resolves electrical information at different depths by measuring electric and / or magnetic fields of different frequencies at the Earth's surface. Among these, the horizontal electric field component has high sensitivity to the resistivity of the underground medium and is a commonly used observation parameter in electromagnetic exploration. For example, magnetotellurics, audio-frequency magnetotellurics, controlled-source audio-frequency magnetotellurics, and wide-area electromagnetic methods all require the measurement of single or multiple electric field components. Therefore, achieving high-precision electric field measurement is a key technical issue in electromagnetic exploration.

[0003] In electromagnetic detection, the electric field is generally measured indirectly by measuring the potential difference between a pair of grounded electrodes. The potential difference generated by the contact between the electrodes and the ground, as well as the range between the electrode pairs, are the main factors affecting the accuracy of the electric field measurement. Non-polarized electrodes achieve conductivity by immersing the metal anode in a corresponding electrolyte solution and utilizing the rapid and reversible redox reaction between the metal and the solution. This isolates the metal electrode from direct contact with the soil, reduces the electrode range, and improves corrosion and oxidation resistance. These are the most commonly used electrodes in electromagnetic detection.

[0004] For non-polarizable electrodes in existing technologies, on the one hand, it is necessary to enhance the contact between the electrode and the ground to reduce the impact of contact resistance. However, on the other hand, the large contact area and the connection between the electrolyte and the ground can lead to rapid electrolyte loss and rapid diffusion of soil impurities into the electrode, reducing the long-term working stability and service life of the electrode. Furthermore, in field construction, electrodes are required to be robust, reliable, easy to insert and remove, and wear-resistant, all of which are difficult to implement with existing structures. Therefore, there is an urgent need for an electrode structure that can improve electrode stability, reduce the rate of impurity diffusion, and improve the ease of electrode installation. To improve electrode working stability, the disclosed technical solutions mainly include the following two: 1) adding fillers such as fumed silica, kaolin, and agarose to the electrolyte solution to enhance the solution's water retention; 2) incorporating small channels, double-layer, or double-cavity structures in the structural design to construct an electrolyte diffusion buffer. Although these solutions improve the stability of the electrode range to some extent by enhancing the solution's water retention or creating a diffusion buffer, they still suffer from problems such as large long-term drift, complex assembly processes, easy formation of cavities, easy wear, and short service life in practical applications. Summary of the Invention

[0005] The purpose of this invention is to provide a bottle-shaped split electrode structure and installation method on a graphene ceramic substrate to solve the above-mentioned problems, thereby improving electrode stability, significantly reducing the rate of impurity diffusion, increasing the service life of the electrode, and improving the convenience of electrode installation.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0008] The chamber has a reaction chamber located on its upper inner side for ionization reactions. The reaction chamber has a conical structure, with the diameter of its top end smaller than that of its bottom end. A fixing bolt is threaded onto the top end of the reaction chamber for easy insertion and removal of electrodes. A reaction electrode rod is inserted into the fixing bolt. A transition chamber located on its lower inner side is used to buffer changes in the concentration of the electrolyte gel and to replenish ions to the reaction chamber. The transition chamber has a cylindrical structure, with the bottom end of the reaction electrode rod located inside the reaction chamber. The reaction chamber and the transition chamber are filled with the electrolyte gel.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0035] Reference Figures 1-2 As shown, this embodiment provides a bottle-shaped split electrode structure on a graphene ceramic substrate, comprising:

[0036] The upper inner side of the chamber 2 is a reaction chamber 201 for ionization reaction. The reaction chamber 201 has a conical structure and the diameter of the top end of the reaction chamber 201 is smaller than the diameter of the bottom end of the reaction chamber 201. The top end of the reaction chamber 201 is threaded with a fixing bolt 1 for easy electrode insertion and removal. A reaction electrode rod is inserted into the fixing bolt 1. The lower inner side of the chamber 2 is a transition chamber 202 for buffering changes in the concentration of electrolyte gel and replenishing ions to the reaction chamber 201. The transition chamber 202 has a cylindrical structure and the bottom end of the reaction electrode rod is located inside the reaction chamber 201. The reaction chamber 201 and the transition chamber 202 are filled with electrolyte gel.

[0037] The buffer chamber 3 is detachably connected to the bottom of the transition chamber 202. The bottom of the buffer chamber 3 is open. A graphene ceramic substrate 5 for sealing electrolyte gel and filtering impurities is snapped between the buffer chamber 3 and the transition chamber 202.

[0038] By using a threaded connection between the integrated chamber 2 and the buffer chamber 3, the surface of the entire device becomes smoother and flatter, reducing wear and facilitating installation. The use of a fixing bolt 1 at the top of chamber 2, with a reaction electrode rod inserted within it, ensures good contact at the wiring points, preventing the connection wires from being affected by external tension, thus increasing reliability and ease of insertion and removal during field operations. The graphene ceramic substrate 5 solves the isolation problem between chamber 2 and the buffer chamber 3, reducing the rate of change in ion concentration in chamber 2, enhancing stability, achieving porous flow distribution, mitigating moisture loss, stabilizing electrode differential, improving electrode lifespan, and preventing cavities at the top of chamber 2. The choice of electrolyte gel is existing technology and will not be elaborated here.

[0039] By using a graphene ceramic substrate 5 as the base, the properties of graphene ceramics can reduce the water loss of the electrolyte gel, allowing for the selection of an electrolyte gel with lower viscosity. Lower viscosity improves electrode sensitivity and accuracy, and reduces electrode differential within the electrode. Furthermore, the pores of the graphene ceramic substrate 5 are on the millimeter scale, allowing impurities to pass through them.

[0040] Further optimization of the scheme: the graphene ceramic substrate 5 uses graphene oxide as the membrane material, and a composite membrane layer is prepared by physical vapor deposition reduction method. Li Bo used porous ceramics as a carrier and graphene oxide (GO) as the membrane material, and obtained graphene oxide porous ceramic composite membrane materials using different methods. Experiments showed that using graphene oxide modified liquid and obtaining a hydrophilic composite membrane by dip-coating method increased the interlayer spacing, resulting in a membrane thickness of 12-20 μm, and its selective permeability increased with decreasing membrane thickness. Using graphene obtained by high-temperature reduction method as raw material and preparing composite membranes by physical deposition and physical vapor deposition methods, graphene is difficult to disperse uniformly, resulting in a lack of dense and uniform membranes. However, the composite membrane layer prepared by physical vapor deposition reduction method has a uniform and dense structure, with better stability and hydrophobicity. This invention uses this method to prepare the graphene ceramic substrate 5, which can improve the effect of impurity isolation and allow electrolyte passage, thereby improving the accuracy of the device.

[0041] In a further optimized design, the bottom periphery of the chamber 2 is provided with an external thread 203, and the inner side of the top of the buffer chamber 3 is provided with an internal thread 301. The external thread 203 and the internal thread 301 are threadedly connected. The cooperation between the external thread 203 and the internal thread 301 can achieve a tight fixation between the chamber 2 and the buffer chamber 3.

[0042] Further optimization involves a fixed inner flange 302 at the bottom inner side of the buffer chamber 3. The inner diameter of the inner flange 302 is smaller than the diameter of the graphene ceramic substrate 5, and the top of the inner flange 302 is in sealed contact with the graphene ceramic substrate 5. By setting the inner flange 302 to engage with the graphene ceramic substrate 5, the graphene ceramic substrate 5 can be held inside the buffer chamber 3 and maintain a stable, sealed state. The bottle-shaped outer shell design of the reaction chamber 201, which is smaller at the top and larger at the bottom, not only facilitates easy insertion and removal operations during field construction but also enhances the safety of the device and improves its overall wear resistance, shock resistance, and impact resistance.

[0043] To further optimize the design, an inner sealing ring 6 is installed between the bottom of the chamber 2 and the top of the graphene ceramic substrate 5, and an outer sealing ring 7 is installed between the bottom of the chamber 2 and the top of the buffer chamber 3. By setting the inner sealing ring 6 and the outer sealing ring 7, the chamber 2 and the buffer chamber 3 can be sealed together, improving the sealing effect.

[0044] The design has been further optimized, with a wiring plug fixedly connected to the top of the fixing bolt 1. The wiring plug is a stable, pluggable aviation plug, and its structural design facilitates easy plugging and unplugging operations for the user.

[0045] A method for installing a bottle-shaped split electrode structure on a graphene ceramic substrate is as follows:

[0046] S1. Install fixing bolt 1; Install fixing bolt 1 on the top of reaction chamber 201 of chamber body 2 to ensure the sealing and stability of the installation, insert reaction electrode rod, and ensure that the reaction electrode rod extends to the required depth.

[0047] S2. Invert the chamber 2 and fill it with electrolyte gel. Since the present invention uses a graphene ceramic substrate 5 as the substrate, the filtration effect of the substrate can be improved and the possibility of electrolyte gel outflow can be reduced. Therefore, it is no longer required that the electrolyte-rich slurry inside has high viscosity. A lower viscosity, such as a yogurt-like slurry, can be prepared, which helps to reduce the range of different parts of the electrolyte gel inside the electrode and improve the ion movement rate.

[0048] S3. After filling, install the graphene ceramic substrate 5 and check the sealing performance;

[0049] S4. Install the buffer chamber 3. Ensure the airtightness of the graphene ceramic substrate 5 and the buffer chamber 3, and ensure the stability of the buffer chamber 3 to prevent it from loosening and detaching, thus affecting the airtightness.

[0050] Example 2: Refer to Figures 3-4As shown, the difference between this embodiment and Embodiment 1 is that a membrane structure 4 is laid on the top of the graphene ceramic substrate 5. The membrane structure 4 is a filter membrane 502, which is a microporous membrane of 1 to 100 nanometers. The filter membrane 502 isolates impurities from the graphene ceramic substrate 5.

[0051] The diameter of the filter membrane 502 is larger than the top diameter of the graphene ceramic substrate 5 and larger than the bottom inner diameter of the chamber 2. The diameter of the filter membrane 502 is smaller than the inner diameter of the buffer chamber 3. The outer edge of the filter membrane 502 is bonded to the sidewall of the graphene ceramic substrate 5, and the top of the filter membrane 502 abuts against the bottom of the chamber 2. The filter membrane 502 is bonded to the periphery of the graphene ceramic substrate 5 using adhesive. The choice of adhesive is existing technology and will not be elaborated here. Through bonding and abutting against the bottom of the chamber 2, the stability, safety, and sealing of the filter membrane 502 can be achieved, allowing ions to be transferred only through the filter membrane 502, thus avoiding contamination of the electrolyte gel.

[0052] Compared to the embodiment that only uses a graphene ceramic substrate 5 as a filter structure to isolate impurities, this embodiment has a better filtration and diversion effect.

[0053] Example 3: Refer to Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that a membrane structure 4 is laid on the top of the graphene ceramic substrate 5. The membrane structure 4 includes a filter membrane 502 and a diversion membrane 501. The diversion membrane 501 is located at the bottom of the filter membrane 502. The diversion membrane 501 is a water-permeable membrane with a pore size of 10 to 100 micrometers, which diverts impurities and electrolyte gel. The filter membrane 502 is a microporous membrane with a pore size of 1 to 100 nanometers, which isolates impurities from the graphene ceramic substrate 5.

[0054] The shunt membrane 501 not only transports ions between its upper and lower sides but also isolates impurities from the graphene ceramic substrate 5 below. By using a shunt membrane 501, ions can be effectively transported, and its small pore size allows it to isolate impurities from the graphene ceramic substrate 5, thus protecting the electrolyte gel. The filter membrane 502 isolates impurities from the graphene ceramic substrate 5, helping to improve the shunt effect of the shunt membrane 501.

[0055] By setting up two types of membranes, namely a diversion membrane 501 and a filter membrane 502, the diversion membrane 501 can transfer ions and support and protect the electrolyte gel, while the filter membrane 502 can isolate impurities that have penetrated from the graphene ceramic substrate 5, thus achieving a better impurity isolation effect and significantly improving the durability of the device.

[0057] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
