Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a rapid soil pollution detection device based on spectral analysis. Background Technology

[0002] Soil pollution refers to the presence of substances in soil that pose a threat to human health or ecosystems. These pollutants may include heavy metals, organic matter, and other substances that may negatively impact soil ecology. Soil pollution mainly originates from multiple sources, including industrial emissions, agricultural activities, urban expansion, and improper waste disposal. Simultaneously, soil pollution can damage soil ecosystems, affecting plant growth and development, and consequently impacting agricultural production. To monitor and assess soil pollution, scientists have developed various methods, among which spectroscopic techniques are crucial. By analyzing the light absorption or emission characteristics of soil samples at different wavelengths, spectroscopic techniques can determine the content of various elements and compounds in the soil. Commonly used spectrometer types include atomic absorption spectrometry, X-ray fluorescence spectrometry, and near-infrared spectrometry. These techniques offer advantages such as non-destructive testing, rapid multi-component analysis, ease of operation, and energy efficiency, playing a vital role in soil pollution monitoring.

[0003] When using spectral technology to detect soil, infrared light emitted from an infrared source is first collimated into a parallel beam by a collimation system before entering the interferometer system. Subsequently, the infrared light is split into two beams, which then merge again after following different paths to form interference light. After passing through the soil, the interference light carries the soil's spectral information and is converted into an electrical signal by a detector. This electrical signal is then sent to a computer via an analog-to-digital converter. The computer performs a rapid Fourier transform calculation, converting the interference signal into an infrared spectrum with wavenumber as the abscissa, thus completing the detection.

[0004] The soil composition detection equipment used above requires sending the soil to be tested to the laboratory for testing, which is cumbersome, inefficient, and costly. In addition, due to the complexity of soil composition, soil texture, moisture, organic matter, iron oxide content, etc., will affect the spectral characteristics of soil. Ex-situ detection of soil samples may be affected by soil degeneration, which will affect the test results. Therefore, we propose a rapid soil pollution detection device based on spectral analysis. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a rapid soil pollution detection device based on spectral analysis to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid soil pollution detection device based on spectral analysis, comprising an outer frame, a detection bracket connected to the top of the outer frame, a detection cavity formed in the middle of the bottom of the outer frame, the detection bracket comprising a lifting electric rod, an equipment slot connected to the bottom of the lifting electric rod, a controller disposed inside the equipment slot, a communication module disposed on one side of the controller, a power supply disposed on one side of the bottom of the controller, a spectrometer module disposed on the other side of the bottom of the controller, a motor frame connected to the top of the lifting electric rod, a collection rod connected to the center of the bottom of the motor frame, a drill bit connected to the bottom of the collection rod, and a groove formed on one side of the drill bit.

[0008] Furthermore, the drill bit is configured to rotate via a collection rod and a motor frame, and the collection rod is raised and lowered in conjunction with the outer frame via a lifting electric rod.

[0009] Furthermore, the outer wall of the drill bit is spiral-shaped, and the groove is recessed along one side of the outer wall of the drill bit.

[0010] Furthermore, the controller is connected to the lifting electric pole, the communication module, and the motor frame wires, and the power supply and equipment slot are fixed by internal threads.

[0011] Furthermore, the outer frame includes an outer cylindrical shell, and a structural frame is connected to the outer walls of the outer cylindrical shell. A base ring is connected to the bottom end of the structural frame, and a padding layer is attached to the bottom surface of the base ring.

[0012] Furthermore, the outer shell is fixedly connected to the base ring around its perimeter by a structural frame, and the padding layer is evenly attached to the perimeter of the bottom surface of the base ring.

[0013] Furthermore, the detection cavity includes a bottom shell cavity, which is opened along the inner wall of the bottom end of the outer shell, and the inner walls of the bottom shell cavity are covered with a fluoroplastic layer, and the inner walls of the fluoroplastic layer are covered with a light-shielding layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This detection device can be controlled by a controller. The lifting electric rod drives the collection rod to descend, and with the drilling structure of the drill bit, it quickly completes the soil collection at the placement location during the rotary drilling process. At the same time, it rises to the detection chamber area and works with the internal spectrometer module to quickly complete the detection, forming an integrated collection and detection process. This improves efficiency and maintains sample stability, which is necessary for detection processes that require a long time.

[0016] This testing device can be connected to the outer shell and the outer wall to form an outer frame. It can be placed in the soil environment to be tested in conjunction with the bottom base ring structure. The padding layer on the bottom of the base ring can increase the friction and maintain the structural stability of the whole structure during the sampling and testing process after placement.

[0017] This testing device has a bottom shell cavity at the bottom end of the outer shell. The fluoroplastic layer on the inner wall of the bottom shell cavity can enhance the overall shell material strength and improve the structural robustness. The light-shielding layer is formed by covering with a light-shielding black film, which can assist in the detection of internal light and provide a good testing environment.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figure 1-4 The above-displayed rapid soil pollution detection device includes an outer frame 1, a detection support 2 connected to the top of the outer frame 1, a detection cavity 3 opened in the middle of the bottom of the outer frame 1, the outer frame 1 includes an outer shell 101, and a structural frame 102 is connected to the outer walls of the outer shell 101. A base ring 103 is connected to the bottom of the structural frame 102, and a pad 104 is attached to the bottom surface of the base ring 103.

[0029] To ensure the structural stability of this testing device during use, such as Figure 1 As shown, this testing device can be connected to the outer shell 101 and the outer wall structural frame 102 to form an outer frame. It can be placed in the soil environment to be tested in conjunction with the bottom base ring 103 structure. The pad 104 on the bottom surface of the base ring 103 can increase the friction and maintain the structural stability of the overall structure during the sampling and testing process after placement.

[0030] like Figure 2-3 As shown, the detection bracket 2 includes a lifting electric rod 201. The bottom end of the lifting electric rod 201 is connected to an equipment slot 202. A controller 203 is installed inside the equipment slot 202. A communication module 204 is installed on one side of the controller 203, and a power supply 205 is installed on one side of the bottom of the controller 203. A spectrometer module 206 is installed on the other side of the bottom of the controller 203. A motor frame 207 is connected to the top of the lifting electric rod 201, and a collection rod 208 is connected to the center of the bottom end of the motor frame 207. A drill bit 209 is connected to the bottom end of the collection rod 208, and a groove 210 is opened on one side of the drill bit 209.

[0031] To maintain a rapid testing process and improve testing efficiency and convenience, such as Figure 2-3As shown, this detection device can be controlled by controller 203, which is controlled by a single-chip microcomputer. The lifting electric rod 201 drives the collection rod 208 to descend, and with the drilling structure of the drill bit 209, the soil is quickly collected at the placement position during the rotary drilling process. At the same time, it rises to the detection chamber 3 area, and with the internal spectrometer module 206, the detection is quickly completed, forming an integrated collection and detection process. This improves efficiency and maintains sample stability, which is necessary for detection processes that require a long time.

[0032] like Figure 4 As shown, the detection cavity 3 includes a bottom shell cavity 301, which is opened along the inner wall of the bottom end of the outer shell 101, and the inner walls of the bottom shell cavity 301 are covered with a fluoroplastic layer 302, and the inner walls of the fluoroplastic layer 302 are covered with a light-shielding layer 303.

[0033] Finally, in order to provide a good testing environment, such as Figure 4 As shown, this detection device has a bottom shell cavity 301 at the bottom end of the outer shell 101. The fluoroplastic layer 302 on the inner wall of the bottom shell cavity 301 can improve the overall shell material strength and structural robustness. The light-shielding layer 303 is formed by covering with a light-shielding black film, which can assist in the detection of internal light and provide a good detection environment.

[0034] In summary, when using this detection device, the user first places the device with the soil environment via the base ring 103. When the entire device is placed on the ground of the soil environment to be tested, it should be aligned and adjusted to keep it as level as possible. Then, the controller 203 controls the lifting electric rod 201 to descend, which drives the connected motor frame 207 to descend synchronously. The descending motor frame 207 simultaneously lowers the collection rod 208 connected to the bottom axis until it contacts the soil. At this time, the motor frame 207 can be started, driving the collection rod 208 and the drill bit 209 connected to the motor frame 207 to rotate synchronously. The drilling can be adapted to the required soil depth. When the drill bit 209 is inserted into a... After reaching a certain depth, the lifting electric rod 201 operates again, driving the acquisition rod 208 to rise and pull out the drill bit 209 until the position of the trench 210 of the drill bit 209 rises to the height of the detection cavity 3 and is aligned with the spectrometer module 206. At this time, the infrared light source of the spectrometer module 206 emits interference light that has been processed by the interferometer. After the interference light passes through the soil sample in the trench 210, it carries the spectral information of the sample and is received by the detector on the other side of the detection cavity 3. After being converted into an electrical signal, it is transmitted by the communication module 204 and sent to the computer through the analog-to-digital converter. The computer performs rapid calculations and converts the interference signal into an infrared spectrum with wavenumber as the abscissa, thus completing the detection process.
