Description

Technical Field

[0001] This utility model relates to the field of soil salinity component sampling technology, and more specifically to a real-time monitoring device for salinized soil. Background Technology

[0002] Salinization is a significant factor affecting farmland soil quality and the stability of building foundations. If not monitored and controlled in a timely manner, it can lead to problems such as surface crystallization and whitening, stunted plant growth, and corrosion of foundation structures. Therefore, periodic or real-time monitoring of soil salt content is necessary to understand the migration trends and accumulation intensity of salt. Existing salt monitoring methods mainly rely on intelligent sensors, conductivity probes, or chemical analysis devices. While these methods offer high accuracy, they generally suffer from drawbacks such as complex structures, high costs, dependence on power supplies and external equipment, and unsuitability for long-term field deployment. Furthermore, many traditional devices cannot provide "visual" observation of salt changes, nor can they achieve continuous replacement of test strips or detection media and long-term recording, limiting their application in actual fields or foundation construction sites. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a real-time monitoring device for salinized soil to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a real-time monitoring device for salinized soil, comprising a device body, the top of which is provided with a top cover, characterized in that the device body further includes a sampling monitoring module, the sampling monitoring module comprising:

[0005] Mounting shaft, which is fixedly installed inside the housing;

[0006] The test strip roll is spirally fitted onto the outer surface of the mounting shaft, with one side extending to the outside of the housing;

[0007] A contact clip is fixedly installed on one side of the bottom end of the housing, with its top end extending into the interior of the housing and contacting the outer surface of the test paper roll.

[0008] The upper liquid tube is fixedly installed at the bottom of the contact clamp and extends into the soil for sampling. By incorporating a sampling monitoring module, it achieves continuous colorimetric monitoring through the natural migration of saline water via capillary structures without the need for a power source, thus solving the problems of existing salinity monitoring equipment that rely on intelligent sensors, have complex structures, and are difficult to deploy long-term.

[0009] Furthermore, a brine guide rope is fixedly installed inside the liquid inlet pipe. The brine guide rope is made of capillary material, with its main body being a glass fiber rope, and its bottom end extends into the soil. By setting up the brine guide rope, the device can stably guide the saline solution in the soil to the detection area through capillary action, thereby improving its adaptability and sensitivity in low-salt soil environments.

[0010] Furthermore, an anti-permeability clip is fixedly installed on one side of the inner shell, and the test strip roll is placed inside the anti-permeability clip and in close contact with the inner wall of the clip. By setting the anti-permeability clip, the diffusion area of ​​saline solution is limited, and the color reaction is concentrated at a specific location on the test strip, thereby improving the color development stability and observation accuracy.

[0011] Furthermore, a support plate is fixedly installed at the bottom of the outer shell. One side of the support plate is fixedly connected to the upper liquid pipe, and two support columns are fixedly installed at the top of the support plate. The support columns are connected to the bottom of the outer shell. By setting up the support plate and support columns, the overall structure is stable and not easily tipped over after being vertically inserted into the soil, which facilitates the long-term fixed installation of the equipment in the field for monitoring.

[0012] Furthermore, an observation slot is provided at the front of the outer casing, directly in front of the contact clip. A sun-proof observation window is movably mounted on one side of the observation slot via a pivot. By providing this sun-proof observation window, ultraviolet rays and strong light are blocked, preventing fading or misjudgment of the test strip's color development area and improving the reliability of visual readings.

[0013] Furthermore, the sun-proof observation window is fixedly equipped with observation scale lines, and ultraviolet-resistant tinted glass is also fixedly embedded in the window. By setting the observation scale lines, it is possible to facilitate manual judgment of the salt rise height and diffusion rate, making the salt migration trend visible and aiding in data recording and manual intervention.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention, by incorporating a sampling and monitoring module, achieves continuous colorimetric monitoring of salt water through natural capillary migration without the need for a power source, thus solving the problems of existing salt monitoring equipment that rely on intelligent sensors, have complex structures, and are difficult to deploy for extended periods.

[0016] This invention, by incorporating a salt water guide rope, achieves the effect of stably guiding salt water in the soil to the detection area through capillary action, thereby improving the adaptability and sensitivity of the device in low-salt-concentration soil environments.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0023] Reference Figure 1 and Figure 2 This utility model provides a real-time monitoring device for salinized soil, including a main body with a top cover 110 at the top. The main body also includes a sampling and monitoring module, which includes:

[0024] Mounting shaft 111 is fixedly installed inside the housing 100;

[0025] Test strip roll 112 is spirally sleeved on the outer surface of mounting shaft 111, with one side extending to the outside of housing 100. Test strip roll 112 is made of polypropylene fiber base material and coated with a modified bromophenol blue colorimetric agent and chloride ion indicator combination layer. It can change color after contacting salt water, showing a reaction area that changes from light yellow to orange-red or dark purple, which is easy to identify visually.

[0026] Contact clip 113 is fixedly installed on one side of the bottom end of housing 100, with its top end extending into the interior of housing 100 and contacting the outer surface of test paper roll 112.

[0027] The liquid inlet tube 114 is fixedly installed at the bottom end of the contact clamp 113 and extends into the soil for sampling.

[0028] A brine guide rope 115 is fixedly installed inside the upper liquid pipe 114. The brine guide rope 115 is made of capillary material, and its main body is a glass fiber rope. The brine guide rope 115 is made of glass fiber capillary rope, model GF-CAP-3.0, which has good hydrophilicity and microporous adsorption capacity. It can stably transport brine in the soil upward to the inside of the equipment. The bottom end of the brine guide rope 115 extends into the soil.

[0029] Working principle: This invention uses a salt water guide rope 115 to naturally move the salt and moisture in the soil to the contact clip 113 area using capillary action, where it contacts the bottom of the test strip roll 112. Once the salt water wets the paper strip, the colorimetric reagent reacts with chloride ions or other salt ions in the solution, producing a noticeable color change. Users can read the color development height and intensity through the viewing window area on the outer casing 100, judging the distance the salt water rises on the test strip, thus determining the salt migration trend and intensity distribution. This device requires no power supply or intelligent module control, relying solely on its own structure to complete passive continuous monitoring. It can be deployed in the field for extended periods, solving the problems of high cost, dependence on power supply, and easy failure of traditional sensing devices.

[0030] Furthermore, the test strip roll 112 adopts a spiral winding structure. Its unwound portion is supported and fixed by the mounting shaft 111, while the unfolded end extends out of the outer shell 100 to the outside of the device. After the color-developing area between the contact clip 113 and the anti-permeability clip 116 has been fully stained by the saline solution, the user can pull the external extension section to slowly extract the test strip along the spiral path of the outer shell, allowing a new undeveloped strip of paper to enter the observation area and come into contact with the saline solution transmitted by the saline guide rope 115 for color development. The developed strip of paper can be manually torn off and discarded, ensuring continuous test strip renewal. This structure enables real-time monitoring with multiple cycles and segment progression without replacing the main body of the test strip, making it suitable for long-term, phased, and low-intervention observation of saline migration and changes in the field. Example 2

[0031] Reference Figure 1 The difference between Embodiment 2 and Embodiment 1 is that: an anti-permeability clip 116 is fixedly installed on one side of the inner side of the outer shell 100, and the test paper roll 112 is placed inside the anti-permeability clip 116 and is in contact with the inner wall of the anti-permeability clip 116.

[0032] A support plate 117 is fixedly installed at the bottom of the outer casing 100. One side of the support plate 117 is fixedly connected to the upper liquid pipe 114. Two support columns 118 are fixedly installed at the top of the support plate 117 and are connected to the bottom of the outer casing 100.

[0033] An observation slot is provided at the front of the outer casing 100. The observation slot is located directly in front of the contact clip 113. A sun-proof observation window 119 is movably installed on one side of the observation slot via a pivot.

[0034] An observation scale line 120 is fixedly installed on the sun-proof observation window 119, and UV-resistant dark glass is fixedly embedded in the sun-proof observation window 119.

[0035] Working principle: By setting the parameters, the saline solution penetration range can be limited to a specific area of ​​the test strip, preventing lateral diffusion and resulting in misjudgment of color development. The overall device's structural stability is significantly enhanced after insertion into the soil, making it adaptable to outdoor environments such as wind and high temperatures. The sun-proof observation window 119 and the observation scale 120, along with the dark glass color-developing background, not only prevent ultraviolet light from interfering with the color development reaction but also make the readings clearer and more accurate, helping users determine the height and speed of salt migration under different lighting conditions. This embodiment further improves the device's adaptability, stability, and data readability in real-world scenarios.
