Description

Technical Field

[0001] The invention belongs to the technical field of soil monitoring, and in particular relates to a real-time soil heavy metal monitoring device. Background Art

[0002] Soil monitoring refers to determining the environmental quality (or degree of pollution) of the soil and its changing trend by measuring the representative values ​​of factors that affect the soil environmental quality. The main purpose of soil monitoring is to understand the status of soil environmental quality, prevent and control the hazards of soil pollution, and dynamically analyze and determine the degree and development trend of soil pollution. Through soil monitoring, soil pollution can be discovered in a timely manner, and appropriate measures can be taken to avoid further deterioration of soil pollution. Heavy metal pollution in soil refers to the phenomenon that the content of heavy metal elements in the soil is significantly higher than its natural background value, causing ecological damage and deterioration of environmental quality. In order to be able to understand the content of heavy metals in the soil in a timely manner, it is necessary to monitor the heavy metals in the soil in real time. For example, the Chinese utility model patent with publication number: CN208046916U discloses a soil heavy metal online monitoring device, which includes a remote server, a relay node and a distributed monitoring node technical solution. Each monitoring node includes a data processing module, a wireless networking module, a heavy metal monitoring module, a numbering setting module and a power submodule. The heavy metal monitoring sensor of the heavy metal monitoring module can monitor the heavy metals in the soil, and can realize wireless networking, unmanned operation, real-time online monitoring and reporting of data. It has the technical characteristics of easy use, high measurement accuracy and strong anti-destruction.

[0003] However, when the heavy metal monitoring sensor is installed and used, due to the lack of soil penetration mechanism, it can generally only monitor the heavy metal content in the soil surface, while the heavy metal content in the deep soil layer cannot be monitored, which leads to limitations in the use of the heavy metal monitoring sensor and cannot meet relevant usage requirements.

[0004] Therefore, in response to the above technical problems, it is necessary to provide a real-time soil heavy metal monitoring device.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0008] In one or more embodiments of the present invention, the end cover and the ground-breaking part are both threadedly connected to the penetration pipe, which facilitates the separation of the penetration pipe, the end cover and the ground-breaking part, so as to respectively maintain the penetration pipe, the end cover and the ground-breaking part, and also facilitates the replacement of the heavy metal monitoring sensor body; The penetration tube, end cover and soil-breaking part are all made of hard metal materials, which ensure the overall strength of the soil penetration mechanism so that the soil penetration mechanism will not deform when inserted into the soil, thereby ensuring that the heavy metal monitoring sensor body can safely and stably monitor the heavy metal content in the soil.

[0009] In one or more embodiments of the present invention, the end cap is integrally connected to the mounting portion to ensure the integrity of the connection between the end cap and the mounting portion; The length of the mounting portion is greater than half the length of the penetration pipe, so that the heavy metal monitoring sensor body installed at the end of the mounting portion can be close to the ground-breaking portion.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, a real-time soil heavy metal monitoring device in an embodiment of the present invention includes a heavy metal monitoring module, and the heavy metal monitoring module includes a heavy metal monitoring sensor body 1 and a soil penetration mechanism 2.

[0023] Among them, the heavy metal monitoring sensor body 1 is used to monitor the heavy metal content in the soil. The heavy metal monitoring sensor body 1 is a commercially available product and can be purchased and used directly.

[0024] like Figures 1 to 8 As shown, the soil penetration mechanism 2 is arranged on the outside of the heavy metal monitoring sensor body 1. The heavy metal monitoring sensor body 1 penetrates into the deep soil through the soil penetration mechanism 2, so that the heavy metal monitoring sensor body 1 can monitor the heavy metal content in the deep soil, thereby expanding the application scope of the heavy metal monitoring sensor body 1 to meet the user's usage needs.

[0025] The soil penetration mechanism 2 includes a penetration tube 201, and the two ends of the penetration tube 201 are respectively connected with an end cap 202 and a soil breaking part 203. When the end cap 202 and the soil breaking part 203 are connected to the penetration tube 201, the soil penetration mechanism 2 as a whole can form an integrated structure, so that the soil penetration mechanism 2 can be penetrated into the soil layer, so that the heavy metal monitoring sensor body 1 can monitor the heavy metal content in the deep soil.

[0026] Preferably, the end cover 202 and the ground-breaking part 203 are both threadedly connected to the penetration tube 201, which facilitates the separation of the penetration tube 201, the end cover 202 and the ground-breaking part 203, so as to maintain the penetration tube 201, the end cover 202 and the ground-breaking part 203 respectively, and at the same time, it is also convenient to replace the heavy metal monitoring sensor body 1.

[0027] In addition, the penetration tube 201, the end cover 202 and the soil-breaking part 203 are all made of hard metal materials, which ensures the overall strength of the soil penetration mechanism 2, so that the soil penetration mechanism 2 will not deform when inserted into the soil, thereby ensuring that the heavy metal monitoring sensor body 1 can safely and stably monitor the heavy metal content in the soil.

[0028] like Figures 1 to 8 As shown, a plurality of inner ribs 2011 are connected to the inner wall of the penetration tube 201 , and the plurality of inner ribs 2011 are in contact with the outer wall of the mounting portion 204 . The inner ribs 2011 correspond to the infiltration holes 205 , and the inner ribs 2011 can play a role in strengthening the strength of the penetration tube 201 .

[0029] When the end cap 202 is connected to the deep-penetrating tube 201, the mounting portion 204 is inserted into the deep-penetrating tube 201, and a plurality of temporary storage cavities can be formed by the mutual cooperation of the deep-penetrating tube 201, the inner rib 2011 and the mounting portion 204, that is, Figure 1 In the state shown, when the blocking plate 2027 is separated from the covering of the infiltration hole 205, the temporary storage cavity can be used to temporarily store the soil leachate of the corresponding layer.

[0030] Among them, a connecting pipe 2012 is installed on each inner rib 2011, the upper end of each connecting pipe 2012 is connected to the corresponding temporary storage cavity, and the lower end of each connecting pipe 2012 extends to the bottom position of the deep pipe 201. A second solenoid valve 2013 is installed on the connecting pipe 2012, and the bottom end of the connecting pipe 2012 is arranged on the upper side of the ground-breaking part 203.

[0031] When the second solenoid valve 2013 is opened, the soil leachate temporarily stored in the temporary storage chamber can be quickly gathered to the bottom of the deep pipe 201 through the connecting pipe 2012, and then the heavy metal content of the soil leachate can be detected by the heavy metal monitoring sensor body 1, thereby greatly improving the efficiency of soil heavy metal content detection. At the same time, the soil leachate can be pre-stored and quickly transported to the bottom, which is convenient for rapid detection, thereby increasing the frequency of soil heavy metal monitoring.

[0032] like Figures 1 to 8As shown, the end cover 202 is provided with an installation cavity 2021, and a power supply 2022 and a control unit 2023 are installed in the installation cavity 2021, and the power supply 2022 is electrically connected to the control unit 2023. The power supply 2022 is used to supply power to the heavy metal monitoring sensor body 1, the control unit 2023, the first solenoid valve and the second solenoid valve 2013. The control unit 2023 is used to control the operation of the first solenoid valve, the electric cylinder 2026 and the second solenoid valve 2013.

[0033] Preferably, a wireless networking module is provided in the control unit 2023, and the data monitored by the heavy metal monitoring sensor body 1 will be transmitted to the control unit 2023. The control unit 2023 uses the wireless networking module to send the monitoring data to the staff backend terminal to achieve unattended, real-time online monitoring of the heavy metal content in the soil.

[0034] Among them, a cable cavity 2024 is provided in the installation portion 204 , and the heavy metal monitoring sensor body 1 is electrically connected to the control unit 2023 through a cable, and the cable is provided in the cable cavity 2024 .

[0035] In addition, a handle 2025 is installed on the end cover 202, which is convenient for the staff to insert the soil penetration mechanism 2 into the soil, and also convenient for taking out the soil penetration mechanism 2 from the soil.

[0036] like Figures 1 to 8 As shown, a release chamber 2031 is provided in the earth-breaking part 203 , a release pipe 2032 is connected between the penetration tube 201 and the release chamber 2031 , a first solenoid valve is installed on the release pipe 2032 , and the first solenoid valve is electrically connected to the control unit 2023 .

[0037] When the first solenoid valve is opened, the soil leachate in the deep pipe 201 will enter the release chamber 2031 through the release pipe 2032 to empty the soil leachate in the deep pipe 201 so as to monitor the heavy metal content in other layers of soil.

[0038] The side wall of the soil breaking part 203 is provided with a plurality of through holes 2033, and the release chamber 2031 is connected to the outside through the through holes 2033. The soil leachate in the release chamber 2031 can be discharged to the lower soil through the through holes 2033, and will not affect the normal monitoring of the heavy metal monitoring sensor body 1.

[0039] Preferably, the through hole 2033 is arranged to be inclined downward, so as to prevent the soil leachate outside the soil-breaking part 203 from flowing back into the release chamber 2031 through the through hole 2033 .

[0040] In addition, a plurality of protective baffles 2034 are fixedly connected to the outer wall of the soil breaking part 203, and the protective baffles 2034 correspond to the through holes 2033. The protective baffles 2034 can protect the through holes 2033. When the soil penetrating mechanism 2 is inserted into the soil, the protective baffles 2034 can prevent the soil from entering the release chamber 2031 through the through holes 2033, thereby preventing the release chamber 2031 from being blocked by the soil and preventing the through holes 2033 from being blocked.

[0041] like Figures 1 to 8 As shown, the end cap 202 is connected with a mounting portion 204, which is arranged in the deep tube 201, and the end of the mounting portion 204 is provided with a mounting groove, and the heavy metal monitoring sensor body 1 is installed in the mounting groove. The mounting portion 204 cooperates with the inner rib 2011 to form a plurality of temporary storage cavities, and at the same time, the mounting portion 204 is also used to install the heavy metal monitoring sensor body 1.

[0042] Preferably, the end cover 202 and the mounting portion 204 are integrally formed and connected to ensure the integrity of the connection between the end cover 202 and the mounting portion 204 .

[0043] Among them, the length of the installation part 204 is greater than half the length of the penetration tube 201, so that the heavy metal monitoring sensor body 1 installed at the end of the installation part 204 can be close to the ground-breaking part 203. Even when there is a low liquid level of soil leachate in the penetration tube 201, the heavy metal content of the soil leachate can be measured, thereby greatly shortening the time that the soil leachate gathers in the penetration tube 201, thereby ensuring the monitoring efficiency of the heavy metal monitoring sensor body 1.

[0044] In addition, a plurality of infiltration holes 205 are staggered on the side wall of the penetration tube 201, and the interior of the penetration tube 201 is connected to the outside through the infiltration holes 205. When the soil penetration mechanism 2 is inserted into the soil, the soil leachate can enter the penetration tube 201 through the infiltration holes 205 and gather in the penetration tube 201. The heavy metal monitoring sensor body 1 can detect the heavy metal content in the current soil leachate by contacting the soil leachate, so as to achieve the purpose of monitoring the heavy metal content in the soil.

[0045] Preferably, the plurality of infiltration holes 205 are staggered relative to each other to avoid affecting the entry of soil leachate.

[0046] like Figures 1 to 8As shown, the side wall of the mounting portion 204 is provided with a plurality of blocking mechanisms, which correspond to the plurality of infiltration holes 205. The blocking and releasing of the infiltration holes 205 can be controlled by the blocking mechanisms. When the infiltration holes 205 are released, the soil leachate of the corresponding layer will enter the penetration tube 201, and then the heavy metal monitoring sensor body 1 is used for detection to know the heavy metal content of the current layer of soil. When the infiltration holes 205 are blocked, the soil leachate will not enter the penetration tube 201.

[0047] The blocking mechanism includes an electric cylinder 2026, which is embedded in the mounting portion 204 and electrically connected to the control unit 2023. The electric cylinder 2026 is used to drive the blocking plate 2027 to move so as to block or release the infiltration hole 205.

[0048] In addition, the free end of the electric cylinder 2026 is connected to a blocking plate 2027, which covers the infiltration hole 205. When the blocking plate 2027 blocks the infiltration hole 205, the leachate in the soil will not enter the penetration tube 201 through the infiltration hole 205, thereby avoiding affecting the normal monitoring of the heavy metal monitoring sensor body 1.

[0049] Specifically, the side wall of the mounting portion 204 is provided with an avoidance groove 2028 matching the sealing plate 2027 for accommodating the sealing plate 2027. When the mounting portion 204 is inserted into the deep tube 201, the electric cylinder 2026 is controlled to contract so that the sealing plate 2027 is accommodated in the avoidance groove 2028, so that the mounting portion 204 can pass through several internal ribs 2011 in turn to avoid collision between the sealing plate 2027 and the internal ribs 2011.

[0050] When in use, the end cap 202 and the ground-breaking part 203 are connected to the penetration tube 201 respectively. Figure 6 In the state shown, at this time, the deep pipe 201, the inner rib 2011 and the mounting portion 204 can form a plurality of temporary storage cavities, and the plurality of electric cylinders 2026 are controlled to extend so that the blocking plate 2027 can block the infiltration hole 205. A sealing ring is provided on the side of the inner rib 2011 close to the mounting portion 204 to improve the sealing performance between the inner rib 2011 and the mounting portion 204, thereby preventing the soil leachate in the temporary storage cavity from leaking into the temporary storage cavity below.

[0051] The soil penetration mechanism 2 is inserted into the soil layer as a whole, and the plurality of electric cylinders 2026 are synchronously controlled to contract, so that the blocking plate 2027 is separated from the covering of the infiltration hole 205. The soil leachate will enter the plurality of temporary storage chambers through the plurality of infiltration holes 205 respectively.

[0052] When it is necessary to monitor the heavy metal content in the shallow soil, the second solenoid valve 2013 on the connecting pipe 2012 connected to the uppermost temporary storage chamber is opened. At this time, the soil leachate in the uppermost temporary storage chamber will quickly converge in the deep pipe 201 through the connecting pipe 2012. When the soil leachate contacts the heavy metal monitoring sensor body 1, the heavy metal monitoring sensor body 1 can detect the heavy metal content in the soil leachate, and then monitor the heavy metal content in the shallow soil.

[0053] When it is necessary to monitor the heavy metal content in the deep soil, the first solenoid valve on the release tube 2032 is opened to discharge the soil leachate in the deep tube 201, thereby avoiding monitoring interference caused by soil leachate in different degrees in the deep tube 201. The soil leachate in the deep tube 201 will enter the release chamber 2031 through the release tube 2032, and then be discharged to the lower soil through the through hole 2033, which will not affect the normal monitoring of the heavy metal monitoring sensor body 1.

[0054] Open the second solenoid valve 2013 on the connecting pipe 2012 connected to the bottom temporary storage chamber. Since soil leachate is pre-stored in the bottom temporary storage chamber, the soil leachate in the bottom temporary storage chamber can be quickly gathered in the in-depth pipe 201 through the connecting pipe 2012, and then detected by the heavy metal monitoring sensor body 1, thereby greatly shortening the gathering time of the soil leachate, improving the detection efficiency of the heavy metal monitoring sensor body 1, and also increasing the monitoring frequency of the heavy metal monitoring sensor body 1 on soil heavy metals.

[0055] The data monitored by the heavy metal monitoring sensor body 1 will be sent to the control unit 2023, and the control unit 2023 will send the monitoring data to the staff backend terminal through the wireless networking module to achieve unattended, real-time online monitoring of the heavy metal content in the soil.

[0056] In addition, in order to ensure the real-time monitoring effect of soil heavy metals, the control unit 2023 can be set, that is, the control unit 2023 controls the second solenoid valves 2013 to open from top to bottom in sequence, so that the heavy metals in the soil at different depths can be monitored from top to bottom in sequence.

[0057] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
