Description

Technical Field

[0001] This utility model relates to the field of sensor calibration, specifically a high-precision low-altitude meteorological sensor calibration device. Background Technology

[0002] In the field of meteorological observation, high-precision meteorological sensors are crucial for accurately acquiring meteorological data. Currently, existing low-altitude meteorological sensor calibration devices, in practical applications, utilize the coordinated operation of various components to provide a stable and accurate calibration environment for low-altitude meteorological sensors. Through relevant gas path control components, such as switching valves and shut-off valves, the air pressure parameters during the calibration process can be precisely adjusted to ensure the accuracy and reliability of the calibration.

[0003] Existing barometric pressure sensor calibrators are equipped with a fine-tuning valve, which is a rotating rod structure for fine-tuning of barometric pressure. However, during use, the fine-tuning valve rod must be placed on the edge of a table to allow for some movement, and the rotation angle is limited. This makes it inconvenient for operators at different working heights, mainly due to the limited rotation angle. Therefore, the inventors urgently need to design a fine-tuning valve structure that can be adjusted at multiple angles and has a small rotation radius to improve the convenience of barometric pressure calibration operations. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a high-precision low-altitude meteorological sensor calibration device to solve the technical problems of excessively large rotation radius and single angle of the fine-tuning valve in traditional barometric pressure calibrators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision low-altitude meteorological sensor calibration device, including a barometric pressure calibrator main board. The upper surface of the barometric pressure calibrator main board includes a fine-tuning valve. One end of the fine-tuning valve is connected to a universal joint, and the other end of the universal joint is connected to a fine-tuning valve knob. The fine-tuning valve can be operated by rotating the fine-tuning valve knob. A support is provided at the lower end of the fine-tuning valve knob.

[0006] By adopting the above technical solution, firstly, the high-precision low-altitude meteorological sensor calibration device sets a fine-tuning valve on the main board of the barometric calibrator and connects the fine-tuning valve knob with a universal joint, allowing the operator to conveniently operate the fine-tuning valve by rotating the knob, greatly improving the flexibility and convenience of operation. At the same time, the support at the lower end of the fine-tuning valve knob can be placed horizontally when the fine-tuning valve knob is not in operation, avoiding the impact of knob shaking on adjustment accuracy during operation and ensuring the stability of fine-tuning operation during calibration.

[0007] Furthermore, the surface of the fine-tuning valve knob is provided with an anti-slip texture.

[0008] By adopting the above technical solution, an anti-slip texture is set on the surface of the fine-tuning valve knob, which can effectively increase the friction between the operator's hand and the knob, avoid slippage during operation, ensure that the operator can apply force stably and accurately control the rotation angle of the knob, thereby improving the adjustment accuracy of the fine-tuning valve. At the same time, the presence of the anti-slip texture can ensure a good operating feel, improve the reliability of operation, and reduce adjustment errors caused by slippage.

[0009] Furthermore, a sensor inlet is provided on one side of the upper surface of the main board of the air pressure calibrator.

[0010] By adopting the above technical solution, a dedicated connection position is provided for the low-altitude meteorological sensor to be calibrated, making the installation and disassembly of the sensor more convenient. There is no need to find additional connection points, saving installation time and improving the efficiency of calibration preparation. At the same time, the dedicated sensor interface can ensure the stability of the connection between the sensor and the device, avoiding unstable data transmission or calibration errors caused by loose connections during the calibration process.

[0011] Furthermore, a filter is provided on one side of the upper part of the main board of the barometric pressure calibrator, a switching valve is provided on one side of the filter, a shut-off valve is provided on the other side of the filter, and a pressure relief valve is provided at the front end of the filter.

[0012] By adopting the above technical solutions, the filter can filter the gas entering the device, remove impurities, and prevent impurities from affecting calibration accuracy or damaging internal components. At the same time, the switching valve can flexibly switch between different gas paths to meet the gas path requirements of different calibration scenarios. The shut-off valve can effectively control the opening and closing of the gas path, making it easy to cut off the gas source for related operations when needed. The pressure relief valve can release pressure in time when the gas path pressure is too high, ensuring the safety of device operation.

[0013] Furthermore, the surface of the main board of the barometric pressure calibrator is provided with a calibrator inlet, and a calibration instrument panel is provided above the calibrator inlet.

[0014] By adopting the above technical solution, a convenient interface is provided for connecting the calibrator, which facilitates the rapid docking of the calibrator and the calibration device, ensures the stable transmission of calibration signals, and provides a connection guarantee for the smooth progress of calibration work. At the same time, the calibration instrument panel set on the upper part of the calibrator interface can display various data in real time during the calibration process. Operators can intuitively understand the calibration status, judge in time whether the calibration has achieved the expected effect, and make corresponding adjustments based on the data.

[0015] Furthermore, a pressure rod is provided at the upper end of the filter.

[0016] By adopting the above technical solution, operators can directly pull the pressure rod to pressurize the device, which shortens the operation path, makes it more convenient, and saves time in pressurization. At the same time, the connection between the pressure rod and the filter allows the pressurized gas to be quickly filtered, reducing contamination during transmission and ensuring the quality of the gas entering the subsequent gas path.

[0017] Furthermore, the surface of the mainboard of the air pressure calibrator is made of high-strength aluminum alloy die-casting material.

[0018] By adopting the above technical solutions, high-strength aluminum alloy has high structural strength, which can provide stable support for various components on the device, bear the weight of the components and the forces generated during operation, ensure the stability of the overall structure of the device, and prevent deformation and damage. At the same time, the low density of aluminum alloy can reduce the overall weight of the device, making it easier to transport and install. The die-casting process can ensure the flatness and dimensional accuracy of the main board surface, which is conducive to the precise installation of various components.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model features a fine-tuning valve on the surface of the main board of a barometric pressure calibrator. The fine-tuning valve is connected to the fine-tuning valve knob via a universal joint, allowing the operator to adjust the fine-tuning valve by simply rotating the knob. Furthermore, by utilizing the characteristics of the universal joint, this completely overcomes the limitation of traditional fine-tuning valves that can only be operated at a single angle. Operators no longer need to place the device on the edge of a table; it can be easily operated from different working heights and positions, greatly improving operational convenience.

[0021] 2. This utility model provides a support below the fine-tuning valve knob and provides an anti-slip texture on the surface of the fine-tuning valve knob to prevent slippage, ensure precise control of the knob's rotation angle, and ensure that the adjustment accuracy is not affected by shaking when the knob is not rotated for fine-tuning operations, thus ensuring the accuracy of air pressure fine-tuning and improving the overall accuracy and reliability of low-altitude meteorological sensor calibration.

By adopting the above technical solution, a dedicated connection position is provided for the low-altitude meteorological sensor to be calibrated, making the installation and removal of the sensor more convenient. There is no need to find an additional connection point, saving installation time and improving the efficiency of calibration preparation. At the same time, the dedicated sensor inlet can ensure the stability of the connection between the sensor and the device, avoiding unstable data transmission or calibration errors caused by loose connection during the calibration process. This further ensures that the sensor can accurately receive and feedback calibration signals, providing a reliable connection guarantee for high-precision calibration.
