Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a monitoring device suitable for the environment of municipal solid waste treatment plants. Background Technology

[0002] Environmental monitoring is an activity that involves the regular and systematic detection and assessment of various pollutants generated by the natural environment and human activities. It includes the measurement of environmental elements such as air, water quality, soil, noise, and radiation to assess environmental quality, trace pollution sources, provide early warnings of potential environmental risks, and provide a scientific basis for environmental management and decision-making.

[0003] Air quality testing begins with collecting air samples, typically using specialized samplers capable of collecting particulate matter, gases, and other pollutants from the air. After sampling, the samples are sent to a laboratory or analyzed using portable testing equipment to determine the type and concentration of pollutants. Based on the test results, an assessment is made to determine whether the air quality meets health and safety standards, leading to a conclusion that air pollution exists and to the extent of it. This process is crucial for monitoring and improving air quality.

[0004] The shortcomings of existing technical solutions are that air quality assessments require the collection and testing of air samples. However, many sampling devices are designed for single use, including the filter membrane, sampler, and absorbent liquid. This means they cannot be reused after the initial sampling, making it inconvenient to sample the same environment multiple times. Utility Model Content

[0005] The purpose of this utility model is to provide a monitoring device suitable for the environment of municipal solid waste treatment plants, so as to solve the technical problem that many sampling devices in the prior art are designed for single use and cannot be reused after the initial sampling, making it inconvenient to sample the same environment multiple times.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A monitoring device suitable for municipal solid waste treatment plant environments includes a support base, a mounting plate, and a pressure plate. The mounting plate is fixedly connected to the support base, and the pressure plate is movably hinged to the mounting plate. The mounting plate and the pressure plate cooperate with each other. The mounting plate has an air outlet, and the pressure plate has an air inlet corresponding to the air outlet. A sampling paper fixing component is provided between the mounting plate and the pressure plate for fixing sampling paper. Both the mounting plate and the pressure plate are provided with locking components for maintaining their positions. The mounting plate is provided with an adjusting component for adjusting the rotation angle of the sampling paper fixing component, and the pressure plate is provided with an airflow pushing mechanism for driving airflow into the air inlet.

[0008] As a further embodiment of this utility model: the sampling paper fixing assembly includes a front clamping plate and a rear clamping plate. The front clamping plate has multiple sets of second ventilation holes equidistantly arranged around it, and the rear clamping plate has multiple sets of first ventilation holes corresponding to the second ventilation holes equidistantly arranged around it. The first ventilation holes, the second ventilation holes, and the air inlet and air outlet holes cooperate with each other. The adjusting assembly is connected to the rear clamping plate, and the front clamping plate and the rear clamping plate are connected to each other.

[0009] As a further embodiment of this utility model: the adjustment assembly includes an adjustment knob and a first driving block rotatably connected to the mounting plate, the adjustment knob and the first driving block being coaxially and fixedly connected, the rear clamping plate having a first driving groove that cooperates with the first driving block, and the mounting plate having an adjustment range that cooperates with the adjustment knob.

[0010] As a further embodiment of this utility model: a second driving block is fixedly connected to the middle of the side of the rear clamping plate away from the first driving groove, and a second driving groove that cooperates with the second driving block is opened on the front clamping plate.

[0011] As a further embodiment of this utility model: the airflow driving mechanism includes a motor fixedly connected to the pressure plate, a transmission rod fixedly connected to the output end of the motor, the transmission rod passing through the air inlet and rotatably connected to the pressure plate, an eccentric wheel fixedly connected to the transmission rod at an eccentric position inside the air inlet, a spring fixedly connected inside the air inlet, an air inlet one-way valve cooperating with the eccentric wheel fixedly connected to the output end of the spring, the air inlet one-way valve slidingly cooperating with the air inlet, and an air outlet one-way valve fixedly connected inside the air outlet.

[0012] As a further embodiment of this utility model: the locking component includes a first connecting block and a second connecting block, the first connecting block being fixedly connected to the pressure plate, the second connecting block being fixedly connected to the mounting plate, and the first connecting block and the second connecting block being connected by bolts.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using this invention, after collecting dust particles for a period of time, if sampling is required again, the drive motor can be stopped, the mounting plate and the pressure plate can be turned on, and the adjustment knob can be rotated according to the adjustment range to drive the first and second vent holes corresponding to the air outlet to shift. This makes the sampled part on the sampling paper move away from the air inlet and the other unsampled parts move closer to the air inlet. Finally, ensure that the other set of first vent holes and the other set of second vent holes are coaxially aligned with the air outlet. Then, the pressure plate is fastened onto the mounting plate, and the mounting plate and the pressure plate are fastened together. The above sampling operation can then continue. At this time, the collected sample will be concentrated on another part of the sampling paper, thus completing the adjustment of the part to be sampled on the sampling paper and avoiding mutual interference between samples. By observing the density of solid particles distributed on the sampling paper over a period of time, the degree of air pollution can be determined. At the same time, the sampling paper can be taken to the laboratory for spectral analysis of the dust particles on the sampling paper to analyze their chemical composition and proportion, thereby realizing the detection of air pollution.

[0015] 2. In use, the motor drives the transmission rod to rotate, which in turn drives the eccentric wheel to rotate. The rotation of the eccentric wheel will intermittently push the inlet one-way valve forward, and the spring will intermittently drive the inlet one-way valve to reset. An outlet one-way valve is fixedly connected inside the outlet hole. When the inlet one-way valve moves forward, the outlet one-way valve closes, and the inside of the mounting plate is in a negative pressure state. The external airflow enters the inside of the mounting plate through the inlet hole. When the inlet one-way valve moves backward, it compresses the gas inside the mounting plate, the outlet one-way valve opens, and the inlet one-way valve closes, thereby squeezing the gas inside the mounting plate out of the outlet hole, realizing the effect of continuous airflow inside the mounting plate, so that the airflow continuously passes through the sampling paper, which facilitates the collection of solid dust particles in the airflow by the sampling paper.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-Figure 5 As shown, a monitoring device suitable for the environment of a municipal solid waste treatment plant includes a support base 1, a mounting plate 2, and a pressure plate 5. The mounting plate 2 is fixedly connected to the support base 1, and the pressure plate 5 is movably hinged to the mounting plate 2. The mounting plate 2 and the pressure plate 5 cooperate with each other, and the pressure plate 5 can be fastened onto the mounting plate 2. The mounting plate 2 has an air outlet 4, and the pressure plate 5 has an air inlet 6 corresponding to the air outlet 4. Both the mounting plate 2 and the pressure plate 5 are provided with locking components for maintaining the position of the mounting plate 2 and the pressure plate 5. The locking components include a first connecting block 7 and a second connecting block 19. The first connecting block 7 is fixedly connected to the pressure plate 5, and the second connecting block 19 is fixedly connected to the mounting plate 2. The first connecting block 7 and the second connecting block 19 are connected by bolts, thereby maintaining the fastened state of the mounting plate 2 and the pressure plate 5.

[0025] A sampling paper fixing component is provided between the mounting plate 2 and the pressure plate 5 to fix the sampling paper. The pressure plate 5 is equipped with an airflow driving mechanism 8 to drive airflow into the air inlet 6. External airflow enters through the air inlet 6 under the action of the airflow driving mechanism 8. The sampling paper is responsible for filtering the airflow, and the filtered airflow flows out through the air outlet 4, thereby achieving the collection of solid particles in the air. By observing the density of solid particles on the sampling paper over a period of time, the degree of air pollution can be determined. At the same time, the sampling paper can be taken to the laboratory for spectral analysis of the dust on the sampling paper to analyze its chemical composition. The mounting plate 2 is equipped with an adjustment component for adjusting the rotation angle of the sampling paper fixing component. The sampling paper has a large area, and only a part of it is sampled during sampling. By adjusting the rotation angle of the sampling paper fixing component, the sampled part of the sampling paper is moved away from the air inlet 6, and the other unsampled parts are moved closer to the air inlet 6, thus facilitating the continued sampling operation.

[0026] In some specific implementations, in order to fix the sampling paper, the sampling paper fixing assembly includes a front clamp 14 and a rear clamp 13. The front clamp 14 has multiple sets of second vent holes 20 equidistantly arranged around it, and the rear clamp 13 has multiple sets of first vent holes 15 equidistantly arranged around it, corresponding to the second vent holes 20. The sampling paper is clamped between the front clamp 14 and the rear clamp 13. The first vent holes 15 and the second vent holes 20 cooperate with the air inlet 6 and the air outlet 4. Air flows along the direction of the air inlet 6, a set of second vent holes 20 on the same axis, a set of first vent holes 15 on the same axis, and the air outlet 4, thereby facilitating the filtration operation of the sampling paper.

[0027] In some specific implementations, to adjust the sampling area of ​​the sampling paper, the adjustment assembly includes an adjustment knob 3 and a first driving block 12 rotatably connected to the mounting plate 2. The adjustment knob 3 and the first driving block 12 are coaxially fixedly connected. The adjustment knob 3 can drive the first driving block 12 to rotate. The rear clamping plate 13 has a first driving groove 16 that cooperates with the first driving block 12. The rotation of the first driving block 12 can drive the rear clamping plate 13 to rotate through the first driving groove 16. A fixed connection is made in the middle of the side of the rear clamping plate 13 away from the first driving groove 16. The second driving block 18 has a second driving groove 17 on the front clamping plate 14 that cooperates with the second driving block 18. The rear clamping plate 13 can drive the second driving groove 17 to rotate through the second driving block 18, thereby driving the front clamping plate 14 to rotate, realizing the transfer of the sampling position. The mounting plate 2 is provided with an adjustment range that cooperates with the adjustment knob 3. The adjustment knob 3 is rotated according to the adjustment range to ensure that at least one set of first vent holes 15 and one set of second vent holes 20 are coaxially aligned with the air outlet 4 and the air inlet 6 to complete the air circulation.

[0028] In some specific implementations, to drive airflow into the air inlet 6, the airflow driving mechanism 8 includes a motor 801 fixedly connected to the pressure plate 5. A transmission rod 802 is fixedly connected to the output end of the motor 801. The transmission rod 802 passes through the air inlet 6 and is rotatably connected to the pressure plate 5. An eccentric wheel 803 is eccentrically fixedly connected to the transmission rod 802 inside the air inlet 6. The motor 801 drives the transmission rod 802 to rotate, thereby driving the eccentric wheel 803 to rotate. A spring 10 is fixedly connected inside the air inlet 6. An air intake check valve 11, which cooperates with the eccentric wheel 803, is fixedly connected to the output end of the spring 10. 1. The eccentric wheel 803 rotates intermittently, pushing the intake check valve 11 forward, and the spring 10 intermittently drives the intake check valve 11 to reset. An exhaust check valve 9 is fixedly connected inside the exhaust port 4. When the intake check valve 11 moves forward, the exhaust check valve 9 closes, and the inside of the mounting plate 2 is under negative pressure. External airflow enters the inside of the mounting plate 2 through the intake port 6. When the intake check valve 11 moves backward, it compresses the gas inside the mounting plate 2, the exhaust check valve 9 opens, and the intake check valve 11 closes, thereby squeezing the gas inside the mounting plate 2 out of the exhaust port 4. By repeating the above operation, the airflow continuously flows inside the mounting plate 2.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0030] In use, the sampling paper is placed between the rear clamp 13 and the front clamp 14, so that the second driving block 18 on the rear clamp 13 is inserted into the second driving groove 17 on the front clamp 14, thereby fixing the sampling paper. Then, the rear clamp 13 and the front clamp 14 are placed inside the mounting plate 2, so that the first driving block 12 is inserted into the first driving groove 16. Referring to the adjustment range, the adjustment knob 3 is rotated to rotate the first driving block 12. The rotation of the first driving block 12 can drive the rear clamp 13 to rotate through the first driving groove 16. The rear clamp 13 can drive the second driving groove 17 to rotate through the second driving block 18, thereby driving the front clamp 14 to rotate, thereby adjusting the sampling position and ensuring that at least one set of first vent holes 15 and one set of second vent holes 20 are coaxially aligned with the vent hole 4.

[0031] The pressure plate 5 is fastened to the mounting plate 2, and the first connecting block 7 is connected to the second connecting block 19 by bolts, thereby maintaining the fastening state of the mounting plate 2 and the pressure plate 5. The pressure plate 5 and the mounting plate 2 fix the rear clamping plate 13 and the front clamping plate 14. At this time, there is a set of first vent holes 15, a set of second vent holes 20, and air inlet 6 and air outlet 4 coaxially aligned. The motor 801 drives the transmission rod 802 to rotate, which in turn drives the eccentric wheel 803 to rotate. The rotation of the eccentric wheel 803 will intermittently push the air intake check valve 11 forward, and the spring 10 will intermittently drive the air intake. One-way valve 11 is reset, and an exhaust one-way valve 9 is fixedly connected inside the exhaust port 4. When the intake one-way valve 11 moves forward, the exhaust one-way valve 9 closes, and the inside of the mounting plate 2 is under negative pressure. External airflow enters the inside of the mounting plate 2 through the intake port 6. When the intake one-way valve 11 moves backward, it compresses the gas inside the mounting plate 2, the exhaust one-way valve 9 opens, and the intake one-way valve 11 closes, thereby squeezing the gas inside the mounting plate 2 out of the exhaust port 4, achieving the effect of continuous airflow inside the mounting plate 2, so that the airflow continuously passes through the sampling paper, which facilitates the collection of solid dust particles in the airflow by the sampling paper.

[0032] After collecting samples for a period of time, stop the drive motor 801, unscrew the bolts on the first connecting block 7 and the second connecting block 19 to open the mounting plate 2 and the pressure plate 5. Refer to the adjustment range, rotate the adjustment knob 3 to drive the first vent 15 and the second vent 20 corresponding to the vent 4 to shift, so that the sampled part on the sampling paper is away from the air inlet 6 and the other unsampled parts are close to the air inlet 6. Finally, ensure that the other set of first vent 15 and the other set of second vent 20 are coaxially aligned with the vent 4. Then, fasten the pressure plate 5 onto the mounting plate 2 and connect the first connecting block 7 and the second connecting block 19 with bolts. The above sampling operation can then continue. At this time, the collected samples will be concentrated on another part of the sampling paper, which completes the adjustment of the part to be sampled on the sampling paper and avoids mutual interference between samples.

[0033] After sampling, open the pressure plate 5 and the mounting plate 2, and take the sampling paper out from between the rear clamping plate 13 and the front clamping plate 14. By observing the density of solid particles distributed on the sampling paper over a period of time, the degree of air pollution can be determined. At the same time, the sampling paper can be taken to the laboratory to perform spectral detection on the dust particles on the sampling paper, thereby analyzing the chemical composition and proportion, thus realizing the detection of air pollution.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
