Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude meteorological detection, in particular to a humidity measuring tool for a base measuring box. Background Art

[0002] Conventional high-altitude meteorological detection at home and abroad mainly uses the electronic sounding system. The electronic sounding system is carried into the air by a weather balloon to detect meteorological information such as temperature, humidity, pressure, etc. from the ground to an altitude of 30 kilometers and a radius of 200 kilometers.

[0003] Before the electronic sonde is deployed, it must be placed inside a basic test box for basic testing. The temperature, humidity, and pressure measured by the basic test box are input into the high-altitude meteorological detection software and compared with the temperature, humidity, and pressure data measured by the electronic sonde. This is called basic value determination (hereinafter referred to as basic test). The allowable error range of the basic test has been set in the detection software. As long as the basic test value is input into the computer, it can automatically determine whether the basic test is qualified. If it is within the error range, it is a qualified product and the electronic sonde can be deployed normally. Testing the electronic sonde with a basic test box is the last check on the quality of high-altitude meteorological detection. In recent years, the performance of electronic sondes has gradually improved. As a verification device for electronic sondes, the performance of the basic test box has also improved. Its related test methods and equipment are in urgent need of updating.

[0004] The existing utility model patent with application number CN201920576670.6 discloses an electronic sonde base measurement box, which places constant humidity salt inside the base measurement box to stably create different humidity points, installs a humidity sensor in the base measurement box, and compares the value of the humidity sensor with the humidity value measured by the humidity measurement component of the sonde to determine whether the sonde is qualified. However, due to the volume of some existing base measurement boxes, the dew point meter cannot be placed in the base measurement box, and a dry-wet bulb table is used for calibration, resulting in low humidity measurement accuracy of the base measurement box, which affects the measurement accuracy of the sonde. Although some base measurement boxes are equipped with an installation position for the dew point meter, the dew point meter is easily corroded in the humidity environment generated by the constant humidity salt for a long time, which seriously affects the service life of the dew point meter and the service life of the base measurement box.

[0005] Therefore, it is a technical problem that needs to be solved urgently to design a tooling that can measure the dry-bulb and wet-bulb meters in different types of base test boxes, improve the measurement accuracy, and extend the service life of the dew point meter. Utility Model Content

[0006] The purpose of the utility model is to propose a base measurement box humidity measurement tooling, which can be used for humidity tests of base measurement boxes of different models, to solve the problems in the background technology that the measurement accuracy of the existing dry-bulb and wet-bulb meters is low and the dew point meter in the base measurement box is easily corroded by constant humidity salt, thus affecting the service life of the dew point meter.

[0007] The applicant found that the temperature and humidity calibration box also has a humidity control function, and it is not controlled by constant humidity salt, which will not accelerate the corrosion of the dew point meter and will not affect the service life of the dew point meter. However, the wind speed in the temperature and humidity calibration box is chaotic and uneven, which will affect the measurement of the wet and dry bulb meter. Specifically, the wind speed blowing to the dry bulb and wet bulb in the wet and dry bulb meter is different from the wind speed environment of normal operation, which will affect the measurement results and cause inaccurate measurements.

[0008] In order to detect the dry-bulb and wet-bulb meter of the sonde through a temperature and humidity calibration box, thereby achieving the purpose of calibrating the sonde, the utility model proposes a base measurement box humidity measurement tool, which is located in the temperature and humidity calibration box, and includes a measurement box body with two ends through, a mounting structure arranged on the measurement box body, a dry-bulb and wet-bulb meter installed on the measurement box body through the mounting structure, and a wind control component installed on one end of the measurement box body for controlling air flow.

[0009] Optionally, the measuring box includes a U-shaped base, a mounting plate installed on the U-shaped base, and a blocking structure arranged on the bottom surface of the mounting plate and in contact with one end surface of the U-shaped base; the mounting structure is arranged on the mounting plate; and an air duct is formed between the U-shaped base and the mounting plate.

[0010] Optionally, the blocking structure and the wind control member are located on the same side of the U-shaped base, the length of the mounting plate is greater than the length of the U-shaped base; and the wind control member is located at the opening of the air duct.

[0011] Optionally, the blocking structure includes a blocking block installed at the bottom of the mounting plate, and a first sealing gasket installed on an end surface of the blocking block facing the U-shaped base.

[0012] Optionally, the wind control member is a fan, which pushes the air in the air duct 14 to the outside of the air duct 14.

[0013] Optionally, the mounting plate includes a blocking mounting portion located directly above the U-shaped base, a connecting portion arranged on a side of the blocking mounting portion and located above the blocking block, and the mounting structure is provided on the blocking mounting portion.

[0014] Optionally, the blocking block and the mounting plate are integrally formed.

[0015] Optionally, a second sealing gasket in contact with the top surface of the U-shaped base is installed on the bottom surface of the blocking mounting portion.

[0016] Optionally, the thickness of the blocking mounting portion is less than or equal to the thickness of the connecting portion.

[0017] Optionally, the mounting structure includes a mounting groove arranged on the blocking mounting portion, a limiting groove arranged on the blocking mounting portion and connected to the mounting groove, a first magnet installed in the mounting groove, and an avoidance groove arranged at a middle position of the limiting groove.

[0018] Optionally, the blocking mounting portion is provided with a clamping groove which is connected to the limiting groove.

[0019] Compared with the prior art, the utility model provides a base test box humidity measurement tooling, which has the following beneficial effects:

[0020] The present application ensures measurement accuracy by placing the tooling in a temperature and humidity calibration box, installing a wet-dry bulb meter and a dew point meter in the temperature and humidity calibration box, and measuring humidity through the wet-dry bulb meter and the dew point meter; the humidity in the temperature and humidity calibration box is not controlled by constant humidity salt, and will not corrode the dew point meter, thereby ensuring the service life of the dew point meter; the air flow rate in the measurement box is controlled by a wind control component, ensuring that the dry bulb and wet bulb of the wet-dry bulb meter are in a normal working wind speed environment, thereby ensuring the measurement accuracy of the wet-dry bulb meter.

[0021] In addition, compared with the detection of the wet-and-dry-bulb meter in the basic test box, the temperature and humidity calibration box can also control the temperature. When the wet-and-dry-bulb meter is detected through the basic test box, there is no temperature control system in the base test box. The temperature in the base test box will rise due to the operating temperature of the components, which will have a certain impact on the detection of the wet-and-dry-bulb meter. Therefore, the detection of the wet-and-dry-bulb meter in this application is more in line with the actual situation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is a detailed description in conjunction with the accompanying drawings and specific implementations. In the following description, many specific details are set forth to facilitate a full understanding of the present utility. However, the present utility can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present utility, so the present utility is not limited by the specific embodiments disclosed below.

[0032] A base measurement box humidity measurement tooling of the present application can be used in occasions such as humidity detection of a sounding instrument, and of course can also be used in other similar application scenarios. A base measurement box humidity measurement tooling is described in detail below.

[0033] See attached Figure 1 — Figure 8 As shown, a schematic diagram of the structure of a preferred embodiment of a base measurement box humidity measurement tooling of the present application is shown. The base measurement box humidity measurement tooling includes a measurement box body 1 with two ends connected, a mounting structure 2 arranged on the measurement box body 1, a wet-dry bulb meter 3 mounted on the measurement box body 1 through the mounting structure 2, an air control member 4 mounted on one end of the measurement box body 1 for controlling air flow, and the mounting structure 2.

[0034] The utility model provides an installation position for the installation structure 2, the wet-dry bulb meter 3 and the wind control component 4 through the setting of the measuring box 1, thereby providing necessary conditions for the detection of the sounding instrument; the setting of the installation structure 2 is used to fix the wet-dry bulb meter of the sounding instrument to prevent the wet-dry bulb meter from moving during the detection process; the setting of the wind control component 4 is used to control the wind speed in the measuring box 1 to ensure that the dry bulb and the wet bulb of the wet-dry bulb meter are both located under the same wind speed conditions for detection, thereby ensuring the accuracy of the wet-dry bulb meter detection and the measurement accuracy of the base measuring box; the utility model, through the measuring box 1, in combination with the installation structure 2 and the wind control component 4, allows the wet-dry bulb meter to be detected in a temperature and humidity calibration box, so that the standard detection component dew point meter can detect the wet-dry bulb meter of the sounding instrument in the temperature and humidity calibration box, so that the dew point meter does not need to be in a constant humidity environment produced by constant humidity salt, thereby slowing down the corrosion and rusting of the dew point meter and extending the service life of the dew point meter.

[0035] See attached Figure 1 — Figure 3 , Figure 8 As shown, in the utility model, the measuring box 1 includes a U-shaped base 11, a mounting plate 12 installed on the U-shaped base 11, a blocking structure 13 arranged on the bottom surface of the mounting plate 12 and in contact with one end surface of the U-shaped base 11; the mounting structure 2 is arranged on the mounting plate 12; and an air duct 14 is formed between the U-shaped base 11 and the mounting plate 12.

[0036] The utility model forms an air duct 14 by setting a U-shaped base and a mounting plate 12, so that the interior of the measuring box body 1 can be connected with the interior of the temperature and humidity calibration box, and the temperature and humidity calibration box can control the humidity and temperature of the space in the air duct 14, so that the dry-bulb meter 3 can be tested; by setting a blocking structure 13, the space between the mounting plate 12 and the wind control member 4 and the mounting plate 12 is blocked, that is, the passageway at one end of the air duct 14 is blocked, ensuring that there is only one air outlet position in the air duct 14, that is, the gas in the air duct 14 can only leave the air duct 14 through the wind control member 4, ensuring that the wind control member 4 can control the air flow in the entire air duct 14, ensuring that the wind speed of the environment in which the dry-bulb and wet-bulb in the dry-bulb meter are located can be controlled, and the wind speed environment in which the dry-bulb and wet-bulb are located is the same as the wind speed environment during normal operation, that is, the wind speed and wind direction on the surface of the dry-bulb and wet-bulb are the same.

[0037] See attached Figure 1 — Figure 3 As shown, in the present invention, the blocking structure 13 and the wind control member 4 are located on the same side of the U-shaped base 11 , the length of the mounting plate 12 is greater than the length of the U-shaped base 11 ; the wind control member 4 is located at the opening of the air duct 14 .

[0038] The utility model limits the length of the mounting plate 12 and the length of the U-shaped base 11, thereby ensuring that the mounting plate 12 can provide a mounting position for the blocking structure 13, ensuring that the blocking structure 13 can block the slot at the air outlet end of the air duct 14, and ensuring that the gas in the air duct 14 can only circulate through the wind control component 4.

[0039] See attached Figure 1 and Figure 2 As shown, the blocking structure 13 includes a blocking block 131 installed at the bottom of the mounting plate 12 and a first sealing gasket 132 installed on the end surface of the blocking block 131 facing the U-shaped base 11; the wind control member 4 is a fan, which pushes the air in the air duct 14 to the outside of the air duct 14.

[0040] The utility model sets the wind control part 4 as a fan to discharge the gas in the air duct 14 to the outside. Compared with blowing the gas into the air duct 14, discharging the gas in the air duct 14 reduces the air pressure in the air duct 14, and circulates the gas through the change of air pressure. After the gas is blown into the air duct 14, it is blocked by the dry-bulb meter and the gas flow speed will decrease, which affects the humidity control speed of the temperature and humidity calibration box and the detection efficiency of the dry-bulb meter.

[0041] See attached Figure 1 — Figure 5 As shown, in the present invention, the mounting plate 12 includes a blocking mounting portion 121 located directly above the U-shaped base 11 , a connecting portion 122 arranged on the side of the blocking mounting portion 121 and located above the blocking block 131 , and a mounting structure 2 is provided on the blocking mounting portion 121 .

[0042] The setting of the blocking installation part 121 of the utility model cooperates with the installation structure 2 to provide an installation foundation for the dry-bulb meter 3 and to block the top of the U-shaped base 11; through the setting of the connecting part 122, a mounting position is provided for the blocking block 131 to ensure that the blocking block 131 can block the air duct 14, that is, the blocking block 131 is first installed, and then the blocking block 131 is fitted with the end face of the U-shaped base 11 to ensure the blocking effect of the excess air outlet of the air duct 14. The blocking block 131 can be installed by means of hexagon socket bolts or can be integrally processed and formed with the mounting plate 12.

[0043] See attached Figure 4 and Figure 5 As shown, a second sealing gasket 123 in contact with the top surface of the U-shaped base 11 is installed on the bottom surface of the blocking installation portion 121 .

[0044] The utility model can seal the gap between the sealing mounting portion 121 and the U-shaped base 11 through the provision of the second sealing gasket 123, ensuring that air enters and exits only at the port of the air duct 14, thereby ensuring the stability of other flows in the air duct 14 and ensuring that the dry bulb and wet bulb of the dry-bulb table 3 are in the same wind speed environment.

[0045] See attached Figure 4 and Figure 5 As shown, in the present invention, the thickness of the blocking installation portion 121 is less than or equal to the thickness of the connecting portion 122 .

[0046] The utility model limits the thickness of the second sealing gasket 123, the plugging installation part 121 and the connecting part 122 to ensure the second sealing gasket 123 and to ensure that a limited step is formed between the plugging installation part 121 and the connecting part 122, so as to facilitate the installation of the second sealing gasket 123.

[0047] See attached Figure 1 — Figure 5As shown, in the utility model, the mounting structure 2 includes a mounting groove 21 arranged on the blocking mounting portion 121, a limiting groove 22 arranged on the blocking mounting portion 121 and connected with the mounting groove 21, a first magnet 23 installed in the mounting groove 21, and an avoidance groove 25 arranged at the middle position of the limiting groove 22; wherein, a card groove 24 connected with the limiting groove 22 is provided on the blocking mounting portion 121.

[0048] The utility model is used to limit the installation position of the first magnet 23 through the setting of the installation groove 21. It should be particularly noted that the first magnet 23 is fixedly installed by the hexagon socket bolt, and the mounting plate 12 is also fixedly installed by the hexagon socket bolt; the installation position of the wet-dry bulb meter 3 is limited by the setting of the limit groove 22 and the clamping groove 24, so as to facilitate the installation of the wet-dry bulb meter 3; the avoidance groove 25 is set to ensure that the wet-dry bulb meter 3 can be installed and the measuring end of the wet-dry bulb meter 3 can enter the air duct 14.

[0049] See attached Figure 6 and Figure 7 As shown, in the utility model, the wet-dry bulb meter 3 includes a pick-up plate 31, a limit plate 32 arranged at the bottom of the pick-up plate 31 and corresponding to the limit slot 22, a partition plate 33 installed at the bottom of the limit plate 32 and adapted to the slot 24, a dry-bulb thermometer 34 and a wet-bulb thermometer 35 passing through the pick-up plate 31 and the limit plate 32, a water tank 36 installed on the partition plate 33 and located below the wet-bulb thermometer 35, and a second magnet 37 corresponding to the first magnet 23 is also installed at the bottom of the limit plate 32, and the second magnet 37 can be magnetically attracted to the first magnet 23. It should be particularly noted that the wet-dry bulb meter 3 is a prior art and will not be described in detail here.

[0050] See attached Figure 1 — Figure 8 As shown, the use process of the utility model is as follows:

[0051] In the first step, the user takes the wet-dry-bulb meter 3 to be tested through the taking plate 31, aligns the partition plate 33 with the slot 24 and inserts it until the limiting plate 32 fits with the bottom of the limiting slot 22;

[0052] The second step is to place the measuring tool equipped with the dry-wet bulb meter 3 into the temperature and humidity calibration box equipped with the dew point meter;

[0053] The third step is to connect the wet-dry bulb meter 3 to the basic measuring box, and start the wind control component 4, read the detection data of the wet-dry bulb meter 3 through the basic measuring box, and when the data is stable, compare it with the data of the dew point meter to detect the wet-dry bulb meter 3.

[0054] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
