Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, specifically, it relates to an environmental monitoring sensor probe. Background Technology

[0002] Existing environmental monitoring probes suffer from the following drawbacks: Detection limitations: Traditional sensors still lack sufficient high sensitivity and rapid detection technology for pollutants such as volatile organic compounds (VOCs) and heavy metal ions in air and water. Furthermore, they are inconvenient to maintain, have poor anti-interference capabilities, and are easily corroded by dust and moisture, leading to shortened lifespan. Maintenance is inconvenient: Sensor maintenance or replacement requires complete disassembly, which is cumbersome. Anti-interference capabilities are poor: Multiple sensors arranged together are susceptible to interference from environmental factors such as temperature and humidity, and their protection is insufficient; dust and moisture easily corrode internal circuits, leading to shortened lifespan. Therefore, there is an urgent need for a high-sensitivity detection probe for pollutants adsorbed by microplastics, which balances maintainability and anti-interference capabilities. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an environmental monitoring sensor probe that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an environmental monitoring sensor probe, including a shell assembly, which is divided into an upper cover and a lower cover. One end of the upper cover has a detection cavity, and the end of the lower cover away from the detection cavity has a circuit cavity. The end of the upper cover near the lower cover is provided with an external thread, and the end of the lower cover near the upper cover is provided with an internal threaded sleeve. The internal threaded sleeve and the external threaded sleeve are connected in a threaded seal to physically isolate the detection cavity and the circuit cavity, preventing water vapor and dust from entering the circuit cavity. At the same time, through the adsorption characteristics of fibrous microplastics, the probe can enrich and detect pollutants such as volatile organic compounds and heavy metal ions in the air and water.

[0005] Furthermore, an air passage is provided through the outer side of the top cover for the circulation of air inside the top cover, and a conductive air tube connected to the air passage is provided inside the detection chamber, and a front-end temperature and humidity quick-release plug is fixedly connected inside the detection chamber.

[0006] Furthermore, the two ends of the airway are fixedly connected to a left-side quick-release gas plug, and the end of the airway near the left-side quick-release gas plug is fixedly connected to a hydrophobic membrane, which can be used to separate water vapor.

[0007] Furthermore, a fibrous microplastic is inserted into the end of the detection chamber away from the circuit chamber. A magnet is used at the end of the fibrous microplastic closer to the inside of the detection chamber to ensure that the fibrous microplastic is tightly connected to the detection chamber. Multiple sets of filter pores are opened on the front side of the fibrous microplastic to filter large particulate impurities in the air. Its internal structure is functionalized to achieve selective adsorption of pollutants.

[0008] Furthermore, a left-side quick-release gas plug is fixedly connected to one end of the airway, and a right-side quick-release particle plug is fixedly connected to the other end. A middle partition is fixedly connected between the left-side quick-release gas plug and the right-side quick-release particle plug.

[0009] Furthermore, a dustproof sponge layer is fixedly connected to one end of the middle partition near the circuit cavity to prevent particulate dust from entering the interior of the circuit cavity.

[0010] Furthermore, air and water in the environment first enter the detection chamber through the filter pores of the fibrous microplastics. The fibrous microplastics are fixed to the front end of the detection chamber by magnetic adsorption. Their functionalized surfaces can efficiently adsorb pollutants such as volatile organic compounds and heavy metal ions, achieving pollutant enrichment while filtering large particulate impurities.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0012] 1. This utility model achieves waterproof and dustproof functions through threaded sealing and magnetic filter design, adapting to complex environments. Combined with the high adsorption performance of fibrous microplastics, it can efficiently enrich and detect pollutants such as volatile organic compounds and heavy metal ions in air and water, reducing the risk of failure.

[0013] 2. The hydrophobic membrane isolates water vapor, and the dustproof sponge blocks dust, reducing interference and improving the accuracy of temperature, humidity, gas, and particle detection.

[0014] 3. The quick-release plug design makes sensor disassembly and replacement convenient and supports flexible upgrades to multiple modules.

[0015] 4. The airway and conduction tube are linked, and the quick-release plug design allows for the simultaneous acquisition of multi-dimensional data such as temperature and humidity, volatile organic compound concentration, and heavy metal ion content, enabling rapid and comprehensive detection of pollutants.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example: Refer to Figures 1-7 An environmental monitoring sensor probe includes a housing assembly 1, which is divided into an upper cover 11 and a lower cover 12. One end of the upper cover 11 has a detection cavity 13, and the end of the lower cover 12 away from the detection cavity 13 has a circuit cavity 14. The end of the upper cover 11 near the lower cover 12 is provided with an external thread 15, and the end of the lower cover 12 near the upper cover 11 is provided with an internal threaded sleeve 16. The internal threaded sleeve 16 and the external thread 15 are connected in a threaded seal.

[0028] An air passage 111 is provided through the outer side of the top cover 11 for the circulation of air inside the top cover 11. A conductive air tube 131 connected to the air passage 111 is provided inside the detection chamber 13. A front-end temperature and humidity quick-release plug 2 is fixedly connected inside the detection chamber 13.

[0029] The two ends of the airway 111 are fixedly connected to the left quick-release gas plug 4. The end of the airway 111 near the left quick-release gas plug 4 is fixedly connected to a hydrophobic membrane 112, which can be used to separate water vapor.

[0030] A fibrous microplastic 3 is inserted into one end of the detection cavity 13 away from the circuit cavity 14. A magnet is used at one end of the fibrous microplastic 3 near the inside of the detection cavity 13 to ensure that the fibrous microplastic 3 is tightly connected to the inside of the detection cavity 13. Multiple sets of filter holes 31 are opened on the front side of the fibrous microplastic 3.

[0031] One end of the airway 111 is fixedly connected to a left gas quick-release plug 4, and the other end is fixedly connected to a right particle quick-release plug 5. A middle partition 6 is fixedly connected between the left gas quick-release plug 4 and the right particle quick-release plug 5.

[0032] A dustproof sponge layer 7 is fixedly connected to one end of the intermediate partition 6 near the circuit cavity 14 to prevent particulate dust from entering the interior of the circuit cavity 14.

[0033] Air and water in the environment first enter the detection chamber 13 through the filter mesh 31 of the fibrous microplastic 3. The fibrous microplastic 3 is fixed to the front end of the detection chamber 13 by magnetic adsorption. Its functionalized surface can efficiently adsorb pollutants such as volatile organic compounds and heavy metal ions, and achieve pollutant enrichment while filtering large particulate impurities.

[0034] This invention utilizes air and water from the environment, first entering the detection chamber 13 through the filter mesh 31 of fibrous microplastics 3. The fibrous microplastics 3 are magnetically adsorbed and fixed to the front end of the detection chamber 13. Their functionalized surfaces efficiently adsorb pollutants such as volatile organic compounds and heavy metal ions, filtering large particulate impurities while simultaneously enriching the pollutants. The fibrous microplastics 3, magnetically adsorbed to the front end of the detection chamber 13, can filter large particulate impurities in the air, such as dust, debris, and fibrous microplastics 3, and are easy to disassemble and clean, ensuring long-term detection accuracy. The air entering the detection chamber 13 directly contacts the front-end temperature and humidity quick-release plug 2, which has a built-in temperature and humidity sensor that monitors the air temperature and humidity parameters in real time and transmits the signals to the processing circuit in the circuit chamber 14. The air passage 111 is connected to the detection chamber 13 via a conductive air tube 131, guiding airflow through it. The two ends of the air passage 111 are respectively connected to the left gas quick-release plug 4 for volatile organic compound detection and the right particle quick-release plug 5 for particulate matter concentration monitoring. Combined with the fibrous microplastics... The adsorption function of material 3 enables highly sensitive detection of pollutants such as heavy metal ions and volatile organic compounds, achieving multi-dimensional monitoring of air composition. The hydrophobic membrane 112, located near the quick-release plug in the air passage 111, effectively isolates water vapor, preventing moisture from interfering with gas and particle detection, thus improving the stability and lifespan of the sensor. The intermediate partition 6 and the dustproof sponge layer 7 work together to block particles and dust from entering the circuit cavity 14, protecting the internal circuit components from contamination and ensuring the reliability of signal processing. The upper cover 11 and the lower cover 12 are connected by an external thread 15 and an internal threaded sleeve 16 to achieve a threaded seal connection, physically isolating the detection cavity 13 from the circuit cavity 14. This ensures airflow in the detection cavity 13 through the air passage 111 and the conduction air tube 131, while preventing external moisture and dust from entering the circuit cavity 14, thus improving overall protection performance. The processing circuit in the circuit cavity 14 amplifies, converts, and processes the detection signals of temperature, humidity, gas, and particles, and finally transmits them to an external monitoring system through the quick-release plug for real-time acquisition and analysis of environmental parameters.
