[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The following is combined with Figures 1-5 A permeation assembly provided in this embodiment of the present invention includes a permeation element 1 and a fixing element 2, wherein:

[0030] The permeable element 1 includes multiple densely arranged plant filaments 11, which extend in the same direction and form a semi-permeable structure using their own structure.

[0031] The fixing element 2 is used to fix multiple plant filaments 11 so that the permeation element 1 maintains a columnar structure. Specifically, the columnar structure of the permeation element 1 facilitates installation into the reference electrode, and the shape of the permeation element 1 can be set according to the shape of the reference electrode mounting port.

[0032] In this invention, multiple plant filaments 11 are fixed into a columnar structure by fastener 2. The plant filaments 11 form a semi-permeable structure by utilizing their own structure to facilitate ion exchange between the electrolyte solution and the soil. Compared with the current use of ceramic plugs for ion exchange, this method can effectively save energy consumption in the production process and is more energy-efficient and environmentally friendly.

[0033] Specifically, the permeation component of this application forms a semi-permeable structure through densely arranged plant filaments 11, a structure that exhibits unique advantages in soil measurement scenarios. When a reference electrode is buried in the soil for potential measurement, traditional ceramic plugs often suffer from poor contact due to limited contact area, leading to inaccurate measurements. The densely arranged plant filaments 11 significantly increase the contact area with the soil while maintaining adequate permeability. The plant filaments 11 themselves possess a natural microstructure, forming tens of thousands of microchannels. These channels ensure sufficient ion exchange between the copper sulfate solution and the soil while preventing excessive solution loss. Compared to traditional ceramic plugs, the plant filaments 11 do not require high-temperature sintering, avoiding energy consumption and making the production process more environmentally friendly. Furthermore, the use of a fixing element 2 to maintain the columnar structure of the plant filaments 11 not only facilitates installation and replacement but also ensures the uniformity and stability of permeability performance.

[0034] In some embodiments, the plant filaments 11 are bamboo filaments.

[0035] The embodiments of the present application further adopt bamboo filaments as the plant filaments 11, bringing multiple advantages. First, bamboo is a renewable resource, with a short growth cycle of only 3-5 years, far lower than the growth cycle of 10-20 years of other wood, which guarantees sufficient supply of raw materials and lower cost. Second, bamboo has a unique vascular bundle structure with consistent fiber direction, which is very suitable for forming a semi-water permeable structure. In actual application, the fiber direction of the bamboo filaments is consistent with the solution permeation direction, which can form an ideal ion exchange channel. In addition, bamboo itself has excellent mechanical strength and durability, and can still maintain structural stability in a humid environment, which is particularly important for the reference electrode that is buried in the soil for a long time.

[0036] Optionally, the plant filaments 11 in the present application can also use other plants, such as corn stalks, etc.

[0037] In some embodiments, the permeation piece 1 has an arc surface 12 for contacting the soil at one end along the extension direction.

[0038] In the embodiments of the present application, the arc surface 12 is arranged at the end of the permeation piece 1, which solves the key problem of the contact between the reference electrode and the soil. When the reference electrode is inserted into the soil, the arc surface 12 can naturally separate the soil particles, reducing the damage to the soil structure during installation. This design increases the contact area with the soil, reduces the contact resistance, and thus improves the stability and accuracy of the measurement signal. In actual application, the design of the arc surface 12 can also prevent the accumulation of soil particles on the electrode surface, maintaining good ion exchange effect.

[0039] In some embodiments, the arc surface 12 is a convex surface, a concave surface, or a special-shaped curved surface.

[0040] In the embodiments of the present application, various forms of arc surfaces 12 (convex surface, concave surface, or special-shaped curved surface) are provided, so that the permeation assembly can adapt to different soil environments. In soft soil, the convex design can increase the contact pressure and improve the measurement stability; in hard soil, the concave design can reduce the insertion resistance and facilitate installation; the special-shaped curved surface can be customized and optimized according to specific scenarios. This flexible design greatly expands the application range of the product and improves the practicality.

[0041] In some embodiments, the diameter of the bamboo filaments is less than 1 mm, and the gap between the bamboo filaments is less than 0.5 mm.

[0042] In this embodiment of the invention, precise control of the bamboo filament diameter and spacing (diameter < 1 mm, spacing < 0.5 mm) optimizes the permeability. This microscale design is based on in-depth experimental research: when the bamboo filament diameter is less than 1 mm, ideal capillary action can be formed, ensuring slow solution permeation; while the 0.5 mm spacing restriction prevents rapid solution loss. In actual measurements, this precise structural design allows the copper sulfate solution to maintain a stable permeation rate over a longer period, significantly extending the lifespan of the reference electrode. Simultaneously, the dense arrangement of bamboo filaments increases the number of contact points with the soil, improving the stability of the measurement signal.

[0043] In some embodiments, the cross-section of the bamboo strips is circular, square, rhomboid, or irregular.

[0044] In this embodiment of the invention, the diverse designs of the bamboo fiber cross-section (circular, square, rhomboid, or irregular shapes) provide optimized options for different application scenarios. A circular cross-section has the smallest surface area, suitable for scenarios requiring precise control of the permeation rate; square and rhomboid cross-sections increase the surface area, suitable for scenarios requiring faster ion exchange; while irregular shapes can be customized according to specific needs. This flexible design concept allows the permeation component to adapt to different measurement requirements. For example, a circular cross-section with a slower permeation rate can be selected in corrosion monitoring, while other shapes with larger surface areas can be selected in rapid measurement scenarios.

[0045] Specifically, the cross-section of a single bamboo strip is circular. Processing bamboo into fine bamboo strips is a mature technology, which will not be elaborated on here. The cross-section of the processed bamboo strip is generally circular. The bamboo strips are tightly bundled together and then fixed in shape by fixing part 2. The fixed bamboo strips can be cut according to the required length.

[0046] like Figures 1-3 As shown, in some embodiments, the fixing member 2 is a rubber ring 21 sleeved on the outer periphery of the permeation member 1.

[0047] In this embodiment of the invention, the design using a rubber ring 21 as the fixing element 2 has unique advantages. The rubber ring 21 can apply radial pressure evenly, ensuring the tight arrangement of the bamboo filament bundles. In practical applications, this detachable design facilitates maintenance and replacement; when some bamboo filaments are damaged, the entire permeation assembly can be easily replaced. Furthermore, the rubber material has a certain degree of elasticity, enabling it to adapt to thermal expansion and contraction caused by temperature changes, maintaining the stability of the fixing effect.

[0048] like Figures 4-5 As shown, in some embodiments, the fastener 2 is an adhesive 22 that fills the gaps between multiple bamboo strips.

[0049] In the embodiment of the utility model, the bamboo filaments are fixed by filling the gaps between the bamboo filaments with the adhesive 22, forming a stable overall structure. The adhesive 22 not only plays a fixing role, but also effectively fills the gaps between the bamboo filaments, preventing the solution from leaking from the side. This design ensures that ion exchange only occurs at the expected end face, improving the accuracy of the measurement. The use of environmentally friendly adhesive 22 not only ensures the structural strength, but also does not pollute the environment.

[0050] In some embodiments, the adhesive 22 surrounds the outer circumferential side of the plurality of bamboo filaments.

[0051] In the utility model, the surrounding adhesive 22 is arranged on the outer circumference of the bamboo filaments, further improving the sealing performance of the structure. This design has unique advantages in harsh environments, effectively preventing the intrusion of external pollutants and prolonging the service life of the permeation assembly. The surrounding adhesive 22 design also provides additional mechanical strength, allowing the permeation assembly to withstand various stresses during installation and use.

[0052] Specifically, during the manufacturing process of the above-mentioned permeation assembly, the bamboo filaments are first bundled into the required shape, then the bundled bamboo filaments are placed into the mold, the adhesive is poured into the mold, and the adhesive is fully filled into the gaps and outer circumference of the bamboo filaments. After the adhesive is fixed and formed, the mold is opened and the fixed bamboo filaments are taken out, and the permeation assembly is physically cut to the required length, or the end of the permeation assembly is physically polished to an arc surface.

[0053] The permeation assembly fixes the plurality of plant filaments 11 into a columnar structure through the fixing piece 2, and the plant filaments 11 form a semi-water permeable structure by utilizing their own structure to exchange ions between the electrolyte solution and the soil. Compared with the current ion exchange using ceramic plugs, the permeation assembly can effectively save energy during production and manufacturing, and is more energy-saving and environmentally friendly.

[0054] As shown in Figures 6-7 The utility model discloses an embodiment provides a reference electrode, which comprises: a shell 3, the shell 3 has a cavity and an installation port communicating with the cavity;An electrode rod 4, one end of the electrode rod 4 is inserted into the cavity;The above-mentioned permeation assembly is installed at the installation port.

[0055] In the utility model, the permeation assembly is applied to the reference electrode to constitute a complete measurement system solution. This design not only solves the environmental problem of traditional ceramic plugs, but also improves the overall measurement performance. In practical application, when the reference electrode is buried in the soil to measure the potential of the metal structure, the large-area contact characteristic of the permeation assembly significantly reduces the grounding resistance and improves the measurement accuracy. At the same time, the use of environmentally friendly materials enables the abandoned electrode to be naturally degraded, avoiding environmental pollution. This innovative design provides a new choice of both environmental protection and high efficiency for the field of electrochemical measurement.

[0056] Specifically, the shell 3 can adopt a bamboo tube, or can adopt a plastic shell 3, which is not limited here.

[0057] The device embodiments described above are only schematic, wherein the units described as separate components can or can not be physically separate, and the components displayed as units can or can not be physical units, i.e., can be located in one place, or can be distributed on a plurality of network units. Part or all of the modules can be selected to achieve the purpose of the embodiment scheme according to actual needs. Those skilled in the art can understand and implement without creative labor.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
