Description

Technical Field

[0001] The utility model relates to the technical field of meteorological detection, in particular to a sounding instrument base measuring box with a humidity-sensitive capacitor heating function. Background Art

[0002] With the rapid advancement of high-altitude meteorological detection technology, its scope of application continues to expand. From daily weather forecasts to extreme weather warnings and even climate change research, unprecedentedly high standards are being placed on the measurement accuracy of radiosondes. As an important tool for directly penetrating into the atmosphere to measure key meteorological elements such as temperature, humidity, and air pressure, the stability and accuracy of the performance of radiosondes directly determine the reliability of the observation data. Among the many measurement parameters of radiosondes, humidity has become an indispensable part of meteorological observation due to its significant impact on atmospheric processes, precipitation formation, and climate patterns. However, the accurate measurement of humidity faces many challenges. It is easily interfered with by various environmental factors such as ambient temperature, wind speed, air pressure fluctuations, and tiny particles in the air. In particular, temperature changes can significantly affect the saturation of water vapor in the air, thereby increasing the difficulty of humidity measurement.

[0003] To address this challenge, polymer humidity-sensitive capacitors, with their unique advantages, have taken a leading position in the field of humidity measurement in radiosondes. These materials not only offer high sensitivity, enabling rapid responses to even small humidity changes, but also demonstrate excellent consistency and repeatability, ensuring comparability of measurement results across different radiosondes.

[0004] However, despite the excellent performance of polymer humidity-sensitive capacitors, practical applications still face the problem of contamination. In particular, during the long-term storage of radiosondes, and from the time they are removed from their packaging until they are deployed into the atmosphere, pollutants such as acidic gases (such as sulfur dioxide and nitrogen oxides), alkaline dust, and oil mist in the air can easily adhere to the surface of the humidity-sensitive capacitor. These pollutants not only directly hinder the effective contact between the humidity-sensitive capacitor and water vapor, reducing its ability to absorb and dehumidify moisture, but can also chemically alter the surface properties of the humidity-sensitive capacitor, further affecting its measurement accuracy.

[0005] Therefore, in order to solve the above problems, it is socially necessary to develop a radiosonde base measurement box with humidity-sensitive capacitor heating function. Utility Model Content

[0006] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a sounding instrument base measurement box with a humidity-sensitive capacitor heating function, thereby heating the humidity-sensitive capacitor on the sounding instrument detection arm to improve the humidity measurement accuracy of the sounding instrument.

[0010] More preferably, the male spring pin and the female spring pin are pressed against each other and compressed when the upper cover of the base test box is closed, and the compression is between one half and two thirds of the stroke to ensure reliable contact and conduction of the contacts.

[0011] Preferably, a heat insulation seat is additionally provided above the detection arm, and the heat insulation seat is assembled on the upper cover of the base measurement box.

[0014] Preferably, a wire pressing plate is further provided at the bottom of the thermal insulation seat.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model has a compact structure, a high degree of integration and a good measuring effect. By respectively adding a spring thimble male head and a spring thimble female head to the upper cover of the base measuring box and the base of the base measuring box, the spring thimble male head and the spring thimble female head are pressed against each other during the closing process of the upper cover of the base measuring box, and the spring thimble male head and the spring thimble female head are connected to the electrode line of the heating ceramic sheet just above the humidity sensitive capacitor.

[0029] The sounding instrument base measurement box with humidity-sensitive capacitor heating function of this embodiment includes a base measurement box body 4, which includes a base measurement box base 5 and a base measurement box upper cover 6; the base measurement box upper cover 6 is connected to the base measurement box base 5 via a rotating shaft, and a sounding instrument 1 is arranged on the base measurement box base 5, and a heating ceramic piece 8 is arranged on the base measurement box upper cover 6. The detection arm 2 of the sounding instrument 1 extends into the heating cavity between the base measurement box base 5 and the base measurement box upper cover 6; a positioning seat 7 is arranged on the base measurement box base 5, and a positioning boss 13 is arranged on the top of the positioning seat 7. The humidity-sensitive capacitor 3 on the detection arm 2 enters the heating cavity and is positioned through the positioning boss 13; the heating ceramic piece 8 is connected to the power supply through the electrode line. When the base measurement box upper cover 6 is closed, the heating ceramic piece 8 is located directly above the humidity-sensitive capacitor 3 in the positioning seat 7. When the power is turned on, the heating ceramic piece 8 heats the humidity-sensitive capacitor 3.

[0030] In this embodiment, a spring thimble male head 11 is added to the upper cover 6 of the base measuring box, and a spring thimble female head 12 is added to one side of the base measuring box base 5. The spring thimble male head 11 is directly opposite the spring thimble female head 12 during the opening and closing process of the upper cover 6 of the base measuring box; when the upper cover 6 of the base measuring box is closed, the spring thimble male head 11 and the spring thimble female head 12 abut against each other; the spring thimble male head 11 is connected to the electrode wire of the heating ceramic sheet 8, and the spring thimble female head 12 is connected to the power supply; when the spring thimble male head 11 and the spring thimble female head 12 abut against each other, the electrode wire of the heating ceramic sheet 8 is connected to the power supply;

[0031] Furthermore, the male spring pin 11 and the female spring pin 12 are pressed against each other and compressed when the upper cover 6 of the base test box is closed, and the compression is between one-half and two-thirds of the stroke to ensure reliable contact and conduction of the contacts.

[0032] In this embodiment, a heat-insulating seat 9 is provided above the detection arm 2. The heat-insulating seat 9 is mounted on the upper cover 6 of the base measurement box. The heat-insulating seat 9 presses and flattens the detection arm 2 when the upper cover 6 of the base measurement box is closed.

[0033] Furthermore, a mounting cavity for assembling the heating ceramic sheet 8 is provided on the bottom surface of the heat-insulating seat 9, and the heating ceramic sheet 8 is arranged in the mounting cavity;

[0034] Furthermore, when the upper cover 6 of the base test box is closed, the heating ceramic piece 8 is located directly above the humidity-sensitive capacitor 3 , and a gap of 2 mm is left between the heating ceramic piece 8 and the humidity-sensitive capacitor 3 .

After the specified time is reached, open the upper cover 6 of the base measurement box, and the heating ceramic piece 8 is powered off and stops heating due to the separation of the spring thimble male head 11 and the spring thimble female head 12, and then take out the sonde 1.

[0038] The utility model has a reasonable structure and a high degree of integration. The power supply of the electrode wire of the heating ceramic piece 8 is turned on or off by offsetting or separating the spring pin male head 11 and the spring pin female head 12 as the cover is opened and closed, thereby controlling the heating process, facilitating the absorption and release of moisture by the humidity-sensitive capacitor 3, and improving the humidity measurement accuracy of the sounding instrument 1.
