DETAILED DESCRIPTION
[0037] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0038] See also Figures 1 to 9 The present invention provides a technical solution: an atmospheric monitoring pollution tracing and emergency effect evaluation device, comprising a base frame 1 and a data receiving and processing module electrically connected to a terminal module, a power supply module arranged on the base frame 1, and a pump body for collecting gas samples. The base frame 1 is provided with a detection mechanism for detecting gas and changing detection parameters;
[0039] The test mechanism includes two sets of lateral positioning plates 3 provided on the inner wall of the base frame 1, and a set of electrode plates 4 are embedded and fixed on the opposite surfaces of the two sets of lateral positioning plates 3. The two sets of electrode plates 4 are electrically connected to the power module, and the two sets of electrode plates 4 are arranged in series to form a measurement circuit;
[0040] The inner wall of the base frame 1 is provided with an inner chamber for accommodating gas samples, and the base frame 1 is provided with a particle blocking component for filtering particulate matter in the gas in the inner chamber;
[0041] The base frame 1 is fixedly connected to a pressure sensor 25 electrically connected to the data receiving and processing module, and the base frame 1 is provided with a self-pressurizing component that adjusts the pressure value of the pressure sensor 25 according to the current value in the measuring circuit;
[0042] The base frame 1 is provided with a transverse volume component for adjusting the contact area between the two groups of electrode plates 4 and the gas sample in the inner chamber.
[0043] like Figure 1 、 Figure 2 and Figure 8 As shown, when monitoring the atmosphere, the external natural gas is introduced into the inner chamber of the base frame 1 through the pump body. At this time, the collected gas is between the two sets of lateral positioning plates 3. The concentration of pollutants in the gas affects the conductivity of the gas, and the difference in conductivity determines the current value in the measurement circuit. At the same time, driven by the self-pressure component, the change in the current value in the measurement circuit will be converted into the pressure value received by the pressure sensor 25, and then the pressure signal received by the data receiving and processing module will be used to evaluate the atmospheric pollution situation.
[0044] At the same time, the size of atmospheric conductivity mainly depends on the concentration of free charges and the mobility of charges in the atmosphere. In addition to particulate matter in the atmosphere, there are many factors that affect atmospheric conductivity, such as acidic gases, alkaline gases or volatile organic compounds. Among them, when monitoring gaseous pollutants in the atmosphere in industrial areas, if the pressure value of the pressure sensor 25 exceeds the set value during the initial monitoring, it means that the atmosphere at the location of its base frame 1 may be polluted. In order to determine whether the pollutant is a gaseous pollutant, the gas in the inner chamber is filtered and screened by the particle barrier component, that is, the particulate matter in the sampled gas is removed.
[0045] At the same time, if the particulate matter in the sampled gas is intercepted, and the pressure value of the pressure sensor 25 still exceeds the set pressure value, it means that the gas there is determined to be a gas pollutant, and is not caused by a high concentration of particulate matter. At this time, the contact area between the electrode plate 4 and the gas sample is changed through the cross-product component to further verify the monitoring results.
[0046] Among them, in the initial state, the electrode plate 4 is in complete contact with the gas sample in the inner chamber, that is, the contact area between the electrode plate 4 and the gas sample is the largest. The contact area between the electrode plate 4 and the sampled gas is reduced by the cross-product component, thereby reducing the number of paths for the charge to pass through the two groups of electrode plates 4. When the conductivity of the sampled gas remains unchanged, the contact area between the electrode plate 4 and the sampled gas is reduced, thereby increasing the resistance value of the measurement circuit.
[0047] At the same time, by changing the method of measuring the resistance value parameters in the circuit, and combining the pressure value received by the pressure sensor 25 after the resistance change, and comparing the pressure value received by the pressure sensor 25 at this time with the set value, it is further verified whether the concentration of gaseous pollutants exceeds the standard, thereby achieving the purpose of monitoring gaseous pollutants in the atmosphere.
[0048] It should be noted that in order to determine the source direction of the polluted atmosphere by wind direction, a wind direction sensor 2 is fixedly connected to the top plate of the base frame 1. The wind direction sensor 2 is electrically connected to the data receiving and processing module and the power supply module. By setting the wind direction sensor 2 on the base frame 1, the wind direction changes can be monitored in real time, and the direction of the pollution source can be accurately identified, providing a clear target for pollution control and helping to quickly take effective control measures.
[0049] At the same time, in actual use, multiple groups of base frames 1 can be set up in the monitoring area, and the atmospheric pollution situation can be determined by the measured mechanisms set on the multiple groups of base frames 1, and the wind direction sensors 2 set on the multiple groups of base frames 1 can be used to comprehensively determine the direction of pollution source tracing, so as to provide clear goals for pollution control and help to quickly take effective control measures.
[0050] After the pollution source is rectified, the atmospheric pollution situation is monitored in real time through the base frame 1 and the test mechanism arranged thereon. The real-time pressure value of the pressure sensor 25 can be used to further judge and evaluate the rectification effect to ensure that the pollution is effectively controlled, thus forming a complete process from atmospheric monitoring to rectification to effect evaluation, ensuring the effectiveness and sustainability of pollution control.
[0051] In one of the more preferred embodiments, the particle blocking assembly includes two groups of inner frames 5 fixedly connected to the inner wall of the base frame 1, and the inner frames 5 are provided with an I-shaped middle seat 7 driven by an electric push rod and freely moving in the vertical direction. The I-shaped middle seat 7 is provided with an inner clamping seat 8 on the side facing the lateral positioning plate 3, which rises and falls synchronously with the I-shaped middle seat 7 and moves away from the I-shaped middle seat 7 after being at the bottom position of the vertical stroke. The inner clamping seat 8 is provided with a filter cotton 15 for intercepting gaseous particulate matter.
[0052] The inner chamber is provided with a side frame 14, and a groove body 1 is provided on the base frame 1 for the side frame 14 to slide vertically, and the filter cotton 15 is fixedly connected to the inner wall of the side frame 14;
[0053] The inner clamp seat 8 is fixedly connected to a plug-in block 12, and the side frame 14 is provided with a transverse slide 13 for the plug-in block 12 to slide horizontally. The inner frame 5 is provided with a groove body 2 for the I-shaped middle seat 7 to slide vertically.
[0054] A bottom blocking plate 16 is fixedly connected to the bottom of the inner frame 5 and is in contact with the inner clamping seat 8 .
[0055] like Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, the I-shaped center seat 7 is driven to move freely in the vertical direction by an electric push rod fixed on the base frame 1, wherein the trajectory P is the movement trajectory of the I-shaped center seat 7 when it descends, and when the I-shaped center seat 7 initially descends, the inner clamping seat 8 can follow the I-shaped center seat 7 to descend synchronously, and when the lower surface of the inner clamping seat 8 collides with the bottom resistance plate 16, under the restriction of the bottom resistance plate 16, the inner clamping seat 8 cannot continue to follow the I-shaped center seat 7 to descend synchronously.
[0056] At this time, as the I-shaped middle seat 7 continues to descend, the inner clamp seat 8 gradually moves away from the I-shaped middle seat 7, thereby driving the movement trajectory N of the inner clamp seat 8 to be L-shaped, wherein the plug-in block 12 fixed on the inner clamp seat 8 slides horizontally on the side frame 14 through the transverse slide groove 13, and then when the height of the plug-in block 12 changes, the transverse slide groove 13 can drive the height of the side frame 14 and the filter cotton 15 to change synchronously, thereby driving the filter cotton 15 to filter the gas in the inner chamber from top to bottom, so as to eliminate the influence of particulate matter on the conductivity of the gas in the inner chamber.
[0057] Based on the embodiment of the particle blocking assembly, the transverse volume assembly includes a blocking rod 9 that rotates on a fixed axis on the I-shaped middle seat 7, and one end of the blocking rod 9 away from the I-shaped middle seat 7 rotates on a fixed axis on the inner clamping seat 8. The inner clamping seat 8 includes an integrally formed protrusion 10 on the side facing the lateral positioning plate 3, and a vertical slide groove 11 is provided on the lateral positioning plate 3 for sliding connection of the protrusion 10;
[0058] The bottom of the inner frame 5 is fixedly connected to a bottom blocking plate 16 that contacts the inner clamping seat 8 . The bottom of the inner frame 5 includes an integrally formed notch 6 for the horizontal movement of the inner clamping seat 8 .
[0059] The base frame 1 includes an integrally formed convex corner portion 101 corresponding to the lateral positioning plate 3 and used to accommodate the lateral positioning plate 3. The inner wall of the base frame 1 is provided with a groove body 3 for the lateral positioning plate 3 to slide horizontally, and the convex portion 10 never separates from the vertical sliding groove 11.
[0060] like Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, when the I-shaped middle seat 7 initially moves downward under the drive of the electric push rod, since both the I-shaped middle seat 7 and the inner clamp seat 8 are provided with a torsion spring that drives the blocking rod 9 to restore the initial deflection position, the torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. Therefore, under the action of the torsion spring, the inner clamp seat 8 can move downward synchronously with the I-shaped middle seat 7 until the inner clamp seat 8 conflicts with the bottom blocking plate 16 below.
[0061] At the same time, when the inner clamp seat 8 collides with the bottom resistance plate 16, as the I-shaped center seat 7 continues to descend, the inner clamp seat 8 cannot continue to move downward with the I-shaped center seat 7 due to the restriction of the bottom resistance plate 16. At this time, the descending process of the I-shaped center seat 7 will drive the resistance rod 9 to deflect, thereby causing the horizontal distance between the inner clamp seat 8 and the I-shaped center seat 7 to gradually increase, that is, the inner clamp seat 8 can gradually move horizontally away from the I-shaped center seat 7.
[0062] It should be noted that the protruding portion 10 integrally formed on the inner clamp seat 8 is slidably set on the lateral positioning plate 3 through the vertical slide groove 11, and the lateral positioning plate 3 slides on the base frame 1 through the three horizontal levels of the groove body. Therefore, in the process of the inner clamp seat 8 following the synchronous rise and fall of the I-shaped middle seat 7, the height of the lateral positioning plate 3 and the electrode plate 4 fixed thereon will not change. When the inner clamp seat 8 gradually moves away from the I-shaped middle seat 7, the lateral positioning plate 3 can be pushed by the protruding portion 10 to drive the lateral positioning plate 3 to gradually enter the convex corner portion 101, thereby reducing the surface area of the electrode plate 4 corresponding to the inner chamber, thereby increasing the resistance value of the measuring circuit, and further verifying whether the concentration of gaseous pollutants exceeds the standard through the actual pressure value of the pressure sensor 25 after the resistance change, thereby achieving the purpose of monitoring gaseous pollutants in the atmosphere.
[0063] Based on the embodiment of the transverse volume assembly, the self-pressing assembly includes an electromagnetic coil 17 fixedly connected to the base frame 1 and arranged in series with the measuring circuit. The electromagnetic coil 17 is provided with a central shaft 18 arranged coaxially therewith, and a metal ring 19 is fixedly sleeved on the central shaft 18 to magnetically cooperate with the electromagnetic coil 17.
[0064] Two sets of mounting seats 20 are fixedly connected to the base frame 1. The central shaft 18 slides through the two sets of mounting seats 20. A return spring 24 is sleeved on the outer ring of the central shaft 18. The two ends of the return spring 24 are fixedly connected to the metal ring 19 and the mounting seats 20 respectively.
[0065] The center shaft 18 is provided with an end column 21 that contacts the pressure sensor 25 at one end thereof, and a cylindrical cavity 22 is opened on the center shaft 18 for sliding connection of the end column 21. A pressure spring 23 is provided in the cylindrical cavity 22, and the two ends of the pressure spring 23 are fixedly connected to the end column 21 and the center shaft 18 respectively.
[0066] like Figure 1 、 Figure 8 and Figure 9 As shown, the electromagnetic coil 17 is arranged in series between the two sets of electrode plates 4. When the conductivity of the gas in the inner chamber changes, the current value at the location of the electromagnetic coil 17 will also change. When the current value at the electromagnetic coil 17 changes, the magnetism therein will change synchronously.
[0067] Among them, the magnetic size at the electromagnetic coil 17 determines the magnetic attraction force on the metal ring 19, and then under different magnetic attraction forces, the horizontal displacement of the metal ring 19 and the central axis 18 fixed thereto is different. At the same time, an end column 21 is provided at the end of the central axis 18, and the end column 21 is slidably set on the central axis 18. When the end column 21 contacts the pressure end of the pressure sensor 25, the data receiving and processing module will receive a pressure signal from the pressure sensor 25. As the current value at the electromagnetic coil 17 is different, the pressure on the pressure sensor 25 is different, and then the pressure signal received is different. The real-time pressure value received by the pressure sensor 25 is used to judge the atmospheric pollution situation, so as to achieve the purpose of real-time monitoring.
[0068] At the same time, through the reset spring 24 mounted on the center shaft 18, when the current value of the measuring circuit becomes smaller, the elastic potential energy of the reset spring 24 can drive the center shaft 18 to gradually return to its initial position, and then after the current value becomes smaller, the pressure value exerted on the pressure sensor 25 can be reduced.
[0069] The data receiving and processing module receives electrical signals from the pressure sensor 25 and the wind direction sensor 2 through electrical connections, and processes the received signals. The processing process includes but is not limited to signal amplification, filtering, digital signal processing, signal calibration, and feature extraction. At the same time, the pressure signal of the pressure sensor 25 is analyzed, and the conductivity and pollutant concentration of the gas sample are determined based on the change in the pressure value, thereby evaluating the atmospheric pollution situation. The wind direction signal of the wind direction sensor 2 is also received synchronously, and the direction of the pollution source is determined by combining the data of multiple base frames 1. After pollution control, the pressure signal of the pressure sensor 25 is continued to be received, the atmospheric pollution situation is monitored in real time, and the rectification effect is evaluated to ensure that the pollution is effectively controlled.
[0070] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
