Description

Technical Field

[0001] This invention relates to the field of meteorological monitoring technology, specifically to a portable meteorological and icing monitoring station and its usage method. Background Technology

[0002] Portable weather stations, as integrated and mobile meteorological observation devices, can monitor key meteorological parameters such as temperature, humidity, and ice thickness in real time, providing accurate and personalized meteorological services for individual or corporate users.

[0003] This portable weather station features an IP65-rated protective shell and ABS sensor components. The internal humidity sensor monitors humidity using a moisture-sensitive resistor. When humidity increases, the surface of the moisture-sensitive material adsorbs more water molecules, forming conductive ions or altering the charge carrier concentration within the material, thus reducing resistance. When humidity decreases, water molecules detach from the material surface, increasing the resistance. By measuring the resistance change and combining it with calibration data, the current ambient humidity is calculated. The internal ice accumulation sensor monitors ice thickness using microwave detection technology. Based on the differences in feedback information from different substances such as ice, water, and air via microwave signals, it monitors icing information in the sensor's sensitive area.

[0004] Currently, in the use of portable weather stations, when the air flow speed in the external environment is low, the air around the humidity sensor is refreshed slowly, the exchange rate between water vapor molecules and the sensor's humidity-sensing element decreases, resulting in a longer sensor response time. The sensor needs more time to reflect the actual humidity changes, thus causing measurement lag and affecting the reliability of meteorological monitoring. Summary of the Invention

[0008] Furthermore, a toggle plate is rotatably connected to the outer surface of the outer plate, the toggle plate is fixedly connected to the rotating plate, and the outer surface of the toggle plate is provided with straight grooves and arc grooves.

[0009] Furthermore, a side plate is fixedly connected to the outer circumference of the rotating shaft, a turntable wheel is rotatably connected to the outer surface of the side plate, and an arc-shaped block is fixedly connected to the outer surface of the side plate, the arc-shaped block being in contact with the arc groove.

[0010] Furthermore, a micro motor is fixedly connected to the outer surface of the inner plate, and the output shaft of the micro motor is fixedly connected to the rotating shaft.

[0011] Furthermore, there are two rotating shafts, and a transmission gear is fixedly connected to the outer circumference of each of the two rotating shafts. A transmission belt is sleeved between the two transmission gears.

[0012] Furthermore, a second toothed ring is rotatably connected to the outer surface of the fixed ring, the second toothed ring meshes with a rotating gear, a connecting ring is fixedly connected to the outer circumference of the second toothed ring, and a spiral scraper is fixedly connected to the outer surface of the connecting ring.

[0013] Furthermore, an air outlet pipe is fixedly connected between the air outlet chamber and the air ring.

[0014] Furthermore, an air passage is provided between the connecting ring and the air ring, a connecting air rod is fixedly connected to the outer surface of the connecting ring, and an exhaust hole is provided on the outer surface of the connecting air rod.

[0015] Furthermore, it includes the following steps: Step 1: By controlling the rotation of the fan blades, the fan blades drive the air to circulate sequentially along the air intake chamber, the mounting ring, and the air outlet chamber; Step 2: By controlling the rotation of the spiral scraper, the spiral scraper scrapes away the thin layer of ice on the inner wall of the detection cylinder; Step 3: By controlling the intermittent rotation of the humidity-sensitive resistor material, the degree of moisture absorption in each part of the humidity-sensitive resistor material is relatively uniform.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention uses a microwave icing sensor to continuously emit microwave signals at a specific frequency. Based on the characteristic changes of the microwave signal, the algorithm inside the sensor can calculate the current ice thickness. The calculated ice thickness data is output by the sensor in real time. The staff at the monitoring station or related systems can view the ice thickness data in real time and combine it with other meteorological parameters (such as temperature, wind speed, precipitation, etc.) for comprehensive analysis, providing data support for weather forecasting, disaster warning, etc.

[0017] 2. This invention sets up an air intake chamber that passes through a breathable mesh into the mounting ring, and the air inside the mounting ring passes through the breathable mesh into the exhaust chamber, forming a reciprocating circulation of air inside the detection cylinder. The air convection accelerates the heat and humidity exchange between the sensor and the surrounding environment, enabling it to quickly capture changes in temperature and humidity. In scenarios where the temperature rises suddenly or the humidity drops suddenly, the convection design can shorten the sensor response time and reduce hysteresis errors.

[0018] 3. This invention uses spiral scrapers that rotate against the inner wall of the detection cylinder. The scraping action of the two spiral scrapers separates the thin layer of ice from the inner wall of the detection cylinder. After separation, the ice falls downwards to the bottom of the inner wall. The continuous pushing action of the spiral scrapers causes the ice fragments inside the detection cylinder to gradually move outwards, removing them from the cylinder. This prevents the ice layer from accumulating on the inner wall, which would significantly reduce the airflow cross-section inside the cylinder. This ensures a stable airflow within the inlet chamber and improves the accuracy of the humidity-sensitive resistor material in measuring environmental humidity.

[0019] 4. This invention uses multiple vents to uniformly blow air onto the inner wall of the detection cylinder. Icing requires water molecules to arrange themselves in an orderly manner at low temperatures to form ice crystals. Airflow disrupts the arrangement of water molecules, making it difficult for them to form a stable ice crystal structure. In addition, the flowing air can break the surface tension of the water, making it even more difficult for water molecules to gather together and freeze. Thus, this application uses the airflow discharged through the vents to suppress the speed of ice formation on the inner wall of the detection cylinder, thereby reducing the thickness of ice accumulation when the spiral scraper is scraping ice, reducing the difficulty of scraping ice, and ensuring that the two spiral scrapers can effectively remove ice from the inner wall of the detection cylinder.

[0020] 5. This invention uses a rotating plate to drive the humidity-sensitive resistor material to rotate intermittently around the axis of the mounting ring, so that each part of the humidity-sensitive resistor material is evenly close to the air inlet chamber, and the degree of moisture absorption of each part of the humidity-sensitive resistor is relatively uniform, preventing the humidity-sensitive resistor material from becoming oversaturated, thereby maintaining the measurement accuracy of the humidity sensor. The humidity sensor can accurately reflect subtle changes in actual humidity. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] The present invention will be further described below with reference to embodiments. Example 1:

[0026] Please see Figures 1-12 This invention provides a technical solution: a portable meteorological and icing monitoring station and its usage method, comprising: Meteorological monitoring station 1, a microwave icing sensor 11 is fixedly connected to the top of meteorological monitoring station 1, and a detection cylinder 12 is fixedly connected to the outer surface of meteorological monitoring station 1; an inner plate 2, an outer plate 21 and an air ring 22 are fixedly connected to the inner wall of the detection cylinder 12 respectively, a fixed ring 23 is fixedly connected to the inner wall of the air ring 22, an air inlet chamber 24 and an air outlet chamber 25 are provided on the inner wall of the fixed ring 23, an installation ring 26 is fixedly connected to the outer surface of the fixed ring 23, a breathable mesh 27 is fixedly connected to the inner wall of the installation ring 26, a rotating plate 28 is rotatably connected to the outer surface of the installation ring 26, and a humidity-sensitive resistor material 29 is fixedly connected to the outer surface of the rotating plate 28.

[0027] A rotating gear ring 3 is rotatably connected to the outer surface of the air intake chamber 24. A fan blade 31 is fixedly connected to the inner wall of the rotating gear ring 3. A first gear ring 32 is rotatably connected to the outer surface of the fixed ring 23, and the rotating gear ring 3 meshes with the first gear ring 32. A rotating gear 33 is rotatably connected to the outer surface of the fixed ring 23, and the rotating gear 33 meshes with the first gear ring 32. A rotating shaft 34 is rotatably connected between the fixed ring 23 and the inner plate 2, and the rotating shaft 34 is fixedly connected to the rotating gear 33. The rotating fan blade 31 pushes air into the interior of the air intake chamber 24, such as... Figure 5 , Figure 6 and Figure 7 As shown, the air entering the intake chamber 24 passes through the vent mesh 27 and enters the mounting ring 26, as... Figure 8 and Figure 9 As shown, this allows the flowing air to fully contact the humidity-sensitive resistor material 29 inside the mounting ring 26, enabling the humidity sensor to fully exchange with the outside air.

[0028] A toggle plate 4 is rotatably connected to the outer surface of the outer plate 21. The toggle plate 4 is fixedly connected to the rotating plate 28. A straight groove 41 and an arc groove 42 are formed on the outer surface of the toggle plate 4. A side plate 43 is fixedly connected to the outer circumference of the rotating shaft 34. A toggle wheel 44 is rotatably connected to the outer surface of the side plate 43. An arc block 45 is fixedly connected to the outer surface of the side plate 43. The arc block 45 contacts the arc groove 42. During the contact between the arc block 45 and the arc groove 42, under the limiting action of the arc block 45 and the arc groove 42, the toggle plate 4 cannot rotate on the outer surface of the outer plate 21, and the rotating plate 28 and the humidity-sensitive resistor material 29 cannot rotate around the axis of the rotating plate 28. As the arc block 45 and the toggle wheel 44 rotate, the arc block 4... 5. Separate from the arc groove 42, release the arc block 45 from limiting the actuating disc 4 (the actuating disc 4 can rotate around its own axis). At this time, the actuating wheel 44 enters the interior of the straight groove 41. The rotating actuating wheel 44 pushes the actuating disc 4 to rotate at the center of the outer plate 21 through the straight groove 41. When the actuating disc 4 rotates 60 degrees around its own axis, the actuating wheel 44 separates from the straight groove 41, and the arc block 45 contacts the arc groove 42 again. The rotating arc block 45 limits the actuating disc 4 again through the arc groove 42. In this way, as the rotating shaft 34 continues to rotate, the rotating shaft 34 pushes the actuating disc 4 to rotate intermittently around its axis through the side plate 43, the actuating wheel 44 and the arc block 45.

[0029] A micro motor 5 is fixedly connected to the outer surface of the inner plate 2. The output shaft of the micro motor 5 is fixedly connected to the rotating shaft 34. There are two rotating shafts 34. A transmission gear 51 is fixedly connected to the outer circumference of each of the two rotating shafts 34. A transmission belt 52 is sleeved between the two transmission gears 51.

[0030] A second gear ring 6 is rotatably connected to the outer surface of the fixed ring 23. The second gear ring 6 meshes with the rotating gear 33. A connecting ring 61 is fixedly connected to the outer circumference of the second gear ring 6. A spiral scraper 62 is fixedly connected to the outer surface of the connecting ring 61. The two spiral scrapers 62 rotate against the inner wall of the detection cylinder 12, causing the two spiral scrapers 62 to scrape the ice layer on the inner wall of the detection cylinder 12. Under the scraping action of the two spiral scrapers 62, the thin ice layer on the inner wall of the detection cylinder 12 separates from the detection cylinder 12. After the thin ice layer separates from the inner wall of the detection cylinder 12, it falls downward to the bottom of the inner wall of the detection cylinder 12. Under the continuous pushing action of the spiral scrapers 62, the ice fragments inside the detection cylinder 12 gradually move to the outside of the detection cylinder 12, removing the ice fragments inside the detection cylinder 12.

[0031] An air outlet pipe 7 is fixedly connected between the air outlet chamber 25 and the air ring 22; an air passage is provided between the connecting ring 61 and the air ring 22, and a connecting air rod 8 is fixedly connected to the outer surface of the connecting ring 61. An exhaust hole 81 is provided on the outer surface of the connecting air rod 8; multiple exhaust holes 81 blow air evenly onto the inner wall of the detection air cylinder 12. Icing requires water molecules to arrange themselves in an orderly manner at low temperatures to form ice crystals. Air flow will disrupt the arrangement of water molecules, making it difficult for them to form a stable ice crystal structure. In addition, the flowing air can also break the surface tension of the water surface, making it more difficult for water molecules to gather together to freeze. In this way, this application suppresses the speed of ice formation on the inner wall of the detection air cylinder 12 by setting the air flow discharged from the exhaust holes 81, thereby reducing the ice accumulation thickness when the spiral scraper 62 scrapes ice, reducing the difficulty of ice scraping, and ensuring that the two spiral scraper 62 effectively remove ice from the inner wall of the detection air cylinder 12.

[0032] Includes the following steps: Step 1: By controlling the rotation of the fan blade 31, the fan blade 31 drives the air to circulate sequentially along the air inlet chamber 24, the mounting ring 26 and the air outlet chamber 25; Step 2: By controlling the rotation of the spiral scraper 62, the spiral scraper 62 scrapes off the thin layer of ice on the inner wall of the detection cylinder 12; Step 3: By controlling the intermittent rotation of the humidity-sensitive resistor material 29, the degree of moisture absorption of each part of the humidity-sensitive resistor material 29 is relatively uniform.

[0033] Working principle: First step: In practical applications, such as Figure 1 As shown, a microwave icing sensor 11 is installed on the top of the meteorological monitoring station 1. The microwave icing sensor 11 has a built-in microwave transmitter and receiver. The sensor continuously emits microwave signals of a specific frequency. When ice accumulates on or near the sensor surface, the ice will change the propagation path and characteristics of the microwave signal. Based on the characteristic changes of the microwave signal, the algorithm inside the sensor will combine the absorption and reflection laws of the microwave signal by the ice to establish a mathematical model to calculate the ice thickness. Usually, the ice thickness has a certain functional relationship with factors such as the attenuation degree of the microwave signal and the change of reflection intensity. By monitoring the changes of these parameters in real time and substituting them into the preset algorithm, the sensor can calculate the current ice thickness. The calculated ice thickness data will be output by the sensor in real time and usually transmitted to the data acquisition system or cloud platform of the meteorological monitoring station 1 in the form of digital signals through the communication interface. The staff of the monitoring station or related systems can view the ice thickness data in real time and perform comprehensive analysis in combination with other meteorological parameters (such as temperature, wind speed, precipitation, etc.) to provide data support for weather forecasting, disaster warning, etc.

[0034] Second process: In practical applications, such as Figure 2 , Figure 3 and Figure 4 As shown, by starting the micro motor 5, the micro motor 5 drives the rotating shaft 34 to rotate around the axis of the rotating shaft 34 via the output shaft, as... Figure 12 As shown, two rotating shafts 34 are provided, with a transmission gear 51 and a transmission belt 52 between them. Under the transmission action of the transmission gear 51 and the transmission belt 52, the two rotating shafts 34 rotate synchronously. The rotating shaft 34 drives the rotating gear 33 at one end to rotate around the axis of the rotating shaft 34. Under the meshing action of the rotating gear 33 and the first gear ring 32, the two rotating gears 33 drive the first gear ring 32 to rotate on the outer surface of the fixed ring 23. Under the meshing action of the first gear ring 32 and the rotating gear ring 3, the rotating first gear ring 32 drives the two rotating gear rings 3 inside it to rotate on the outer surface of the air intake chamber 24. The two rotating gear rings 3 drive the fan blades 31 inside them to rotate around the axis of the rotating gear ring 3. The rotating fan blades 31 push the air into the interior of the air intake chamber 24, such as... Figure 5 , Figure 6 and Figure 7 As shown, the air entering the intake chamber 24 passes through the vent mesh 27 and enters the mounting ring 26, as... Figure 8 and Figure 9 As shown, this allows the flowing air to fully contact the humidity-sensitive resistor material 29 inside the mounting ring 26, enabling the humidity sensor to fully exchange with the outside air.

[0035] As a further embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the air entering the mounting ring 26 continues to flow, passing through the vent mesh 27 and entering the air outlet chamber 25. The air inside the air outlet chamber 25 flows into the air ring 22 through the air outlet pipe 7. The air inside the air ring 22 enters the connecting air rod 8 through the air passage between it and the connecting ring 61. The air inside the connecting air rod 8 is discharged outward through multiple exhaust holes 81 on its outer surface. In this way, the air is formed to circulate back and forth inside the detection air cylinder 12. The air convection accelerates the heat and humidity exchange between the sensor and the surrounding environment, enabling it to quickly capture changes in temperature and humidity. For example, in scenarios where the temperature rises suddenly or the humidity drops suddenly, the convection design can shorten the sensor response time and reduce hysteresis error.

[0036] Third process: In practical applications, when the ambient temperature of the weather monitoring station 1 is too low and the water vapor content in the air is high (high humidity), the water vapor in the air is easy to condense and freeze on the surface of the opening of the detection cylinder 12. After the inner wall of the detection cylinder 12 freezes, the airflow cross section inside the detection cylinder 12 is reduced, resulting in a reduction or interruption of the airflow into the air inlet chamber 24. The humidity-sensitive resistor material 29 needs a stable airflow to accurately measure the ambient humidity. Insufficient airflow will prevent the humidity sensor from obtaining the real ambient humidity information in time, resulting in delayed or distorted measurement data.

[0037] To overcome the above difficulties, this application adopts the following technical solution: like Figure 3 and Figure 4 As shown, during the rotation of the two rotating gears 33 on the outer surface of the fixed ring 23, under the meshing action of the rotating gears 33 and the second gear ring 6, the two rotating gears 33 drive the second gear ring 6 to rotate on the outer surface of the fixed ring 23. The rotating second gear ring 6 drives the connecting ring 61 on its outer circumference to rotate around the axis of the second gear ring 6. The rotating connecting ring 61 drives the spiral scraper 62 on its outer surface to rotate around the axis of the connecting ring 61. The two spiral scraper 62 rotate against the inner wall of the detection cylinder 12, causing the two spiral scraper 62 to scrape the ice layer on the inner wall of the detection cylinder 12. Under the scraping action of the two spiral scraper 62, This causes the thin ice layer on the inner wall of the detection cylinder 12 to separate from the cylinder 12. After separating from the inner wall of the detection cylinder 12, the thin ice layer falls downward to the bottom of the inner wall of the detection cylinder 12. Under the continuous pushing action of the spiral scraper 62, the ice fragments inside the detection cylinder 12 gradually move to the outside of the detection cylinder 12, removing the ice fragments from the detection cylinder 12. This prevents the ice layer on the inner wall of the detection cylinder 12 from accumulating and thickening, which would cause a significant reduction in the airflow cross section inside the detection cylinder 12. This ensures that the airflow inside the air inlet chamber 24 is in a stable state and improves the accuracy of the humidity-sensitive resistor material 29 in measuring the ambient humidity.

[0038] As a further embodiment of the present invention, when the meteorological monitoring station 1 is used at night, the temperature difference between day and night in the external environment is large and the temperature drops significantly. The moisture in the air is very easy to condense into ice on the inner wall of the detection cylinder 12. The excessive freezing speed results in a large ice thickness when the spiral scraper 62 scrapes the ice, making it more difficult to scrape the ice. The rotating spiral scraper 62 is unable to effectively scrape off the ice layer inside the detection cylinder 12.

[0039] To overcome the above difficulties, this application adopts the following technical solution: like Figure 3 and Figure 4As shown, during the rotation of the connecting ring 61 around the axis of the detection cylinder 12 driven by the second gear ring 6, the connecting ring 61 drives the connecting rod 8 on its outer surface to rotate around the axis of the detection cylinder 12. The connecting rod 8 drives multiple exhaust holes 81 on its outer surface to rotate around the axis of the detection cylinder 12, so that the multiple exhaust holes 81 blow air evenly onto the inner wall of the detection cylinder 12. Icing requires water molecules to arrange themselves in an orderly manner at low temperatures to form ice crystals. Air flow will disrupt the arrangement of water molecules, making it difficult for them to form a stable ice crystal structure. In addition, the flowing air can also break the surface tension of the water surface, making it more difficult for water molecules to gather together to freeze. In this way, this application suppresses the speed of ice formation on the inner wall of the detection cylinder 12 by setting the airflow discharged from the exhaust holes 81, thereby reducing the thickness of ice accumulation when the spiral scraper 62 scrapes ice, reducing the difficulty of ice scraping, and ensuring that the two spiral scraper blades 62 effectively remove ice from the inner wall of the detection cylinder 12.

[0040] Fourth Project: In practical applications, as air passes through the air inlet chamber 24 and the vent mesh 27 into the mounting ring 26, and then through the vent mesh 27 into the outlet chamber 25, the humidity-sensitive resistor material 29 near the air inlet chamber 24 first comes into contact with and absorbs moisture from the air, and the humidity-sensitive resistor material 29 near the outlet chamber 25 comes into contact with and absorbs moisture from the air later. Over time, the humidity-sensitive resistor material 29 near the air inlet chamber 24 is prone to humidity saturation. The working principle of the humidity-sensitive resistor is based on the change in resistance value after the moisture-sensitive material absorbs moisture. In a high-humidity environment, the moisture-sensitive material continuously absorbs water vapor. When humidity saturation is reached, the amount of water molecules adsorbed inside the material tends to stabilize, and the change in resistance value decreases significantly. At this time, the sensitivity of the resistance signal output by the sensor to humidity changes decreases, resulting in a decrease in measurement accuracy and difficulty in accurately reflecting subtle changes in actual humidity.

[0041] To overcome the above difficulties, this application adopts the following technical solution: like Figure 9 , Figure 10 and Figure 11 As shown, as the rotating shaft 34 rotates around its axis, the rotating shaft 34 drives the side plate 43 on its outer circumference to rotate around its axis. The rotating side plate 43 then drives the actuating wheel 44 and the arc-shaped block 45 on its outer surface to rotate around the axis of the rotating shaft 34. (See reference...) Figure 11During the contact between the arc-shaped block 45 and the arc groove 42, under the limiting action of the arc-shaped block 45 and the arc groove 42, the actuating disc 4 cannot rotate on the outer surface of the outer plate 21, and the rotating plate 28 and the humidity-sensitive resistor material 29 cannot rotate around the axis of the rotating plate 28. As the arc-shaped block 45 and the actuating wheel 44 rotate, the arc-shaped block 45 separates from the arc groove 42, releasing the limiting action of the arc-shaped block 45 on the actuating disc 4 (the actuating disc 4 can rotate around its own axis). At this time, the actuating wheel 44 enters the interior of the straight groove 41, and the rotating actuating wheel 44 pushes the actuating disc 4 to rotate at the center of the outer plate 21 through the straight groove 41. When the actuating disc 4 rotates 60 degrees around its own axis, the actuating wheel 44 separates from the straight groove 41, and the arc-shaped block 45 contacts the arc groove 42 again. The rotating arc block 45 again limits the actuating disc 4 through the arc groove 42. In this way, as the rotating shaft 34 continues to rotate, the rotating shaft 34 pushes the actuating disc 4 to rotate intermittently around the axis of the actuating disc 4 through the side plate 43, the actuating wheel 44 and the arc block 45. The actuating disc 4 drives the rotating plate 28 to rotate intermittently around the axis of the rotating plate 28. The rotating plate 28 drives the humidity-sensitive resistor material 29 to rotate intermittently around the axis of the mounting ring 26. This makes each part of the humidity-sensitive resistor material 29 evenly close to the air inlet chamber 24, and the degree of moisture absorption of each part of the humidity-sensitive resistor is relatively uniform. This prevents the humidity-sensitive resistor material 29 from becoming oversaturated, thereby maintaining the measurement accuracy of the humidity sensor. The humidity sensor can accurately reflect the subtle changes in actual humidity.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
