Description

Technical Field

[0001] This application relates to the field of atmospheric particulate matter monitoring technology, and more specifically, to an automatic calibration structure and monitoring instrument. Background Technology

[0002] Suspended particulate matter is a general term for solid and liquid particulate matter (or aerosols) suspended in the atmosphere. Due to differences in origin and formation, its shape, density, particle size, optical, electrical, magnetic, and other physical properties, as well as its chemical composition, vary greatly. The particle size of particulate matter in the atmosphere ranges from 0.001 μm to over 1000 μm. Generally, particles larger than 50 μm in diameter settle to the ground quickly under the influence of gravity, remaining in the atmosphere for a few minutes to a few hours; particles with a diameter of 0.1 μm not only have a longer residence time in the atmosphere but also migrate over long distances.

[0003] The sources of suspended particulate matter can be divided into natural sources and anthropogenic sources. Anthropogenic sources include soot from the combustion of fossil fuels; industrial dust, metal dust, and cement dust from industrial production and construction; and exhaust from automobiles and airplanes. Natural sources include soil dust, volcanic ash, forest fire ash, and sea salt particles.

[0004] In the field of environmental monitoring and control, suspended particulate matter is a common and important pollution indicator in air quality assessment. Monitoring the concentration of particulate matter in the air requires the use of relevant monitoring equipment for measurement. Therefore, under long-term use, the monitoring equipment needs to be calibrated. Utility Model Content

[0005] The purpose of this application is to provide an automatic calibration structure and monitoring instrument that can achieve a high degree of overlap of calibration positions, thereby improving accuracy.

[0006] In a first aspect, embodiments of this application provide an automatic calibration structure, comprising: a support mechanism including a support component and a detection component, the detection component being connected to the support component, and a clearance opening being disposed on one side of the support component; and a calibration mechanism including a drive component, a calibration diaphragm, and a detection plate, the drive component being disposed on the support component and connected to the calibration diaphragm to drive the calibration diaphragm to extend and retract relative to the clearance opening, and the detection plate being connected to the drive component and detected by the detection component to control the detection plate to switch between a first position and a second position.

[0007] In the above implementation process, the drive component is equipped with a calibration diaphragm and a detection plate, and the support component is equipped with a clearance opening. When calibration is required, the drive component operates and moves the calibration diaphragm and the detection plate so that the calibration diaphragm extends out of the clearance opening. When the detection component detects the detection plate in either the first or second position, it controls the drive component to stop working and performs calibration through the calibration diaphragm. After calibration is completed, the drive component restarts and continues to move the calibration diaphragm and the detection plate. The calibration diaphragm retracts from the clearance opening to its original position until the other detection component in either the first or second position detects the detection plate, at which point the drive component stops working. This completes one automatic calibration, achieving a high degree of overlap in calibration positions and improving accuracy.

[0008] In some embodiments, the drive assembly includes a drive member and a linkage member, the drive member being connected to the linkage member, and the linkage member being connected to the detection plate.

[0009] In the above process, after the connecting rod component is connected to the driving end of the driving component, the connecting rod component can rotate under the action of the driving component, thereby driving the calibration diaphragm to move along a straight line, thus realizing the entry and exit of the calibration diaphragm, which can ensure the high overlap of the calibration position and improve accuracy.

[0010] In some embodiments, the connecting rod component includes a crank and a connecting rod, with one end of the crank connected to the drive member and the other end connected to the connecting rod.

[0011] In the above process, the connecting rod is connected to the drive component through the crank, and can rotate under the drive of the drive component, thereby driving the calibration diaphragm to move in a straight line, thus realizing the entry and exit of the calibration diaphragm. This can ensure the high degree of overlap of the calibration position and improve accuracy.

[0012] In some embodiments, the drive assembly further includes a diaphragm base plate connected to the linkage component, and the calibration diaphragm is disposed on the side of the diaphragm base plate near the clearance opening.

[0013] In the above process, the calibration diaphragm is connected to the connecting rod component through the diaphragm base plate. Driven by the connecting rod component, the diaphragm base plate can ensure the stability of the calibration diaphragm during movement, further improving the high degree of overlap of the calibration position.

[0014] In some embodiments, the support assembly includes a fixing plate and a guide component, the fixing plate being connected to the guide component, the fixing plate being provided with the clearance opening, and the guide component being adapted to the diaphragm base plate.

[0015] In the above process, the fixing plate can fix the guide component, and the guide component is equipped with a diaphragm base plate. When the driving component is driven, the diaphragm base plate can move along the distribution direction of the guide component to realize the linear movement of the calibration diaphragm and complete the function of the calibration diaphragm reaching and retracting, which is beneficial to the calibration of the instrument.

[0016] In some embodiments, the guiding component includes a guide seat and a cover plate. The guide seat is provided with a guide groove configured for guiding the diaphragm substrate. The cover plate is connected to the guide seat for covering the diaphragm substrate.

[0017] In the above process, the diaphragm base plate is adapted to the guide seat, which guides the diaphragm base plate. The cover plate is connected to the guide seat to cover the diaphragm base plate, reducing the contamination of the calibration structure by the external environment and facilitating the calibration of the equipment.

[0018] In some embodiments, the support assembly further includes a fixing frame connected to the fixing plate, and the drive member is disposed on one side of the fixing frame.

[0019] In the above implementation process, the fixed frame is connected to the fixed plate, which enables the fixed plate to jointly support the driving components and the support components, which is conducive to the compactness of the overall structure, saves space, and reduces cost.

[0020] In some embodiments, the detection component includes a first detection switch connected to the support component, such that the detection plate rotates to the first position, and after the calibration diaphragm retracts into the interior of the support component, the drive component is controlled to stop driving.

[0021] In the above implementation process, the first detection switch is located at the first position. When the detection plate rotates to the first position, the first detection switch can provide a feedback signal to control the drive component to stop working, thereby realizing the automatic return of the calibration diaphragm and greatly reducing the operation and maintenance costs.

[0022] In some embodiments, the detection component further includes a second detection switch connected to the support component, such that the detection plate rotates to the second position, and after the calibration diaphragm extends out of the clearance opening, the drive component is controlled to stop driving.

[0023] In the above implementation process, the second detection switch is located in the second position. When the detection plate rotates to the second position, a feedback signal can be sent through the second detection switch to control the drive component to stop working, thereby realizing the automatic arrival of the calibration diaphragm and greatly reducing the operation and maintenance cost.

[0024] Secondly, this application also provides a monitoring instrument, including an automatic calibration structure as described in any of the preceding claims.

[0025] Since the monitoring instrument provided in the second aspect includes an automatic calibration structure, the monitoring instrument has all the technical effects of the automatic calibration structure, which will not be elaborated here.

[0026] Other features and advantages of this application will be set forth in the following description, or some features and advantages may be inferred from the description or determined without doubt, or may be learned by practicing the above-described techniques of this application.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0037] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts.

[0040] The calibration membrane is a key component of a particulate matter monitor. Its function is to provide a standard with a known particulate matter concentration for calibration. By comparing the concentration value displayed by the monitor when measuring the calibration membrane with the actual concentration value on the calibration membrane, the accuracy of the monitor's measurement can be assessed, and necessary adjustments can be made to ensure the reliability of the measurement results. Generally speaking, calibration membranes equipped with particulate matter monitors are divided into two categories: manual calibration and automatic calibration. Manual calibration requires regular calibration and maintenance by operation and maintenance personnel, and has a relatively large degree of uncertainty. Automatic calibration, on the other hand, through the instrument's structure and program control, can effectively reduce human error and significantly improve consistency and reliability.

[0041] In view of this, such as Figures 1-5 As shown, in a first aspect, embodiments of this application provide an automatic calibration structure, including: a support mechanism 10, including a support component and a detection component, the detection component being connected to the support component, and a clearance opening being disposed on one side of the support component; and a calibration mechanism 20, including a drive component, a calibration diaphragm 206, and a detection plate 207, the drive component being disposed on the support component and connected to the calibration diaphragm 206 to drive the calibration diaphragm 206 to extend and retract relative to the clearance opening, and the detection plate 207 being connected to the drive component and detected by the detection component to control the detection plate 207 to switch between a first position and a second position.

[0042] For example, the detection component, in cooperation with the detection plate 207, controls the operation of the driving component, which facilitates the positioning and retraction of the calibration diaphragm 206. For ease of structural design, the detection component can be positioned on the side of the support component near the driving end of the driving component. The movement of the calibration diaphragm 206 includes, but is not limited to, linear movement, so that when the driving component is activated, the detection plate 207 is located in either the first position or the second position. One end of the calibration diaphragm 206 passes through the clearance opening from the inside of the support component and extends to the outside of the support component for calibrating the device. After calibration, the calibration diaphragm 206 can return along its original path through the action of the driving component.

[0043] In the above implementation process, the drive component is equipped with a calibration diaphragm 206 and a detection plate 207, and the support component is equipped with a clearance opening. When calibration is required, the drive component operates and drives the calibration diaphragm 206 and the detection plate 207 to move, so that the calibration diaphragm 206 extends out of the clearance opening. When the detection component detects the detection plate 207 in either the first or second position, it controls the drive component to stop working and performs calibration through the detection diaphragm. After calibration is completed, the drive component restarts and continues to drive the calibration diaphragm 206 and the detection plate 207 to move. The calibration diaphragm 206 retracts from the clearance opening to its original position until the other detection component in either the first or second position detects the detection plate 207, at which point the drive component controls the drive component to stop working. This completes one automatic calibration, which can achieve a high degree of overlap of calibration positions and improve accuracy.

[0044] like Figures 1-2 As shown, the drive assembly includes a drive component 201 and a connecting rod component. The drive component 201 includes, but is not limited to, a drive motor. The drive component 201 is connected to the connecting rod component, and the connecting rod component is connected to the detection plate 207.

[0045] In the above process, after the connecting rod component is connected to the driving end of the driving component 201, the connecting rod component can rotate under the action of the driving component 201, which can drive the calibration diaphragm 206 to move along a straight line, thereby realizing the entry and exit of the calibration diaphragm 206, which can ensure the high overlap of the calibration position and improve the accuracy.

[0046] Please refer to again Figure 1 and Figure 2 The connecting rod assembly includes a crank 202 and a connecting rod 203. One end of the crank 202 is connected to the drive member 201, and the other end is connected to the connecting rod 203.

[0047] For example, the crank 202 is connected to the driving end of the driving member 201, and the crank 202 is located below the driving member 201. The connecting rod 203 can be connected to the crank 202 via the rotating shaft 204. When the driving member 201 rotates, the connecting rod 203 can rotate relative to the rotating shaft 204. It is understood that in order to achieve linear movement of the calibration diaphragm 206, in other embodiments, the connecting rod component and the driving member 201 can be arranged at the same horizontal position. For example, the connecting rod component is located on one side of the driving member 201. Through the extension and retraction of the driving member 201, the linear movement of the connecting rod component is achieved, and finally the linear movement of the calibration diaphragm 206 is achieved.

[0048] In the above process, the connecting rod 203 is connected to the drive component 201 through the crank 202. It can move irregularly under the driving action of the drive component 201, thereby driving the calibration diaphragm 206 to move along a straight line, thus realizing the entry and exit of the calibration diaphragm 206. This can ensure the high overlap of the calibration position and improve accuracy.

[0049] like Figures 2-3 As shown, the drive assembly also includes a diaphragm base plate 205, which is connected to the connecting rod component, and the calibration diaphragm 206 is disposed on the side of the diaphragm base plate 205 near the clearance opening. For example, the calibration diaphragm 206 is fixed to the diaphragm base plate 205 by adhesive bonding.

[0050] In the above process, the calibration diaphragm 206 is connected to the connecting rod component through the diaphragm base plate 205. Under the drive of the connecting rod component, the diaphragm base plate 205 can ensure the stability of the calibration diaphragm 206 during the movement process, further improving the high overlap of the calibration position.

[0051] In some embodiments, the support assembly includes a fixing plate 101 and a guide component. The fixing plate 101 is connected to the guide component and is provided with the clearance opening. The guide component is adapted to the diaphragm base plate 205.

[0052] In the above process, the fixing plate 101 can fix the guide component, and the guide component is equipped with a diaphragm base plate 205. When the driving component 201 is driven, the diaphragm base plate 205 can move along the distribution direction of the guide component to realize the linear movement of the calibration diaphragm 206, realize the function of the calibration diaphragm reaching and retracting, and complete the calibration of the instrument.

[0053] like Figure 5 As shown, the guiding component includes a guide seat 102 and a cover plate 103. The guide seat 102 is provided with a guide groove, which is configured to guide the diaphragm base plate 205. The cover plate 103 is connected to the guide seat 102 to cover the diaphragm base plate 205. The connection method between the cover plate 103 and the guide seat 102 can be snap-fit, snap-fit, screw-fit, etc., and no specific limitation is made here. That is to say, both the diaphragm base plate 205 and the calibration diaphragm 206 are located between the guide seat 102 and the cover plate 103.

[0054] In the above process, the diaphragm base plate 205 is adapted to the guide seat 102, and the guide seat 102 can guide the diaphragm base plate 205. The cover plate 103 is connected to the guide seat 102 to cover the diaphragm base plate 205, reduce the pollution of the calibration structure by the external environment, and facilitate the calibration of the equipment.

[0055] In some embodiments, the support assembly further includes a fixing frame 104 connected to the fixing plate 101. The fixing frame 104 is located above the guide seat 102, and the driving member 201 is disposed on the side of the fixing frame 104 away from the guide seat 102. The driving end of the driving member 201 passes through the fixing frame 104 and extends between the fixing frame 104 and the guide seat 102.

[0056] In the above implementation process, the fixing frame 104 is connected to the fixing plate 101, which enables the fixing plate 101 to jointly support the driving component 201 and the supporting components, which is beneficial to the compactness of the overall structure, saves space, and reduces cost investment.

[0057] In some embodiments, the detection component includes a first detection switch 105, which includes, but is not limited to, a photoelectric switch. The first detection switch 105 is connected to the support component so that the detection plate 207 rotates to the first position. After the calibration diaphragm 206 retracts into the interior of the support component, the drive component is controlled to stop driving.

[0058] In the above implementation process, the first detection switch 105 is located at the first position. When the detection plate 207 rotates to the first position, the first detection switch 105 can provide a feedback signal to control the drive component to stop working, thereby realizing the automatic retraction of the calibration diaphragm 206 and greatly reducing the operation and maintenance costs.

[0059] like Figure 1 , Figure 3 and Figure 4 As shown, the detection component also includes a second detection switch 106, which includes, but is not limited to, a photoelectric switch. The first detection switch 105 and the second detection switch 106 can be located on opposite sides of the crank 202. The second detection switch 106 is connected to the support component so that the detection plate 207 rotates to the second position. After the calibration diaphragm 206 extends out of the clearance opening, it controls the drive component to stop driving.

[0060] In the above implementation process, the second detection switch 106 is located in the second position. When the detection plate 207 rotates to the second position, the second detection switch 106 can provide a feedback signal to control the drive component to stop working, thereby realizing the automatic arrival of the calibration diaphragm 206 and greatly reducing the operation and maintenance cost.

[0061] Secondly, this application also provides a monitoring instrument, including the automatic calibration structure described above.

Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also understand that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily essential to this application.
