Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature measurement equipment technology, specifically to a portable high-temperature radiation thermometer. Background Technology
[0002] Portable high-temperature radiation thermometers are non-contact temperature measurement devices based on the blackbody radiation law. They measure temperature by detecting the infrared radiation energy emitted by a target object. This technology overcomes the limitations of traditional contact temperature measurement methods, which require thermal equilibrium time. It is particularly suitable for high-temperature industrial scenarios such as metallurgy, glass manufacturing, and ceramic sintering, enabling rapid and safe temperature monitoring. Its core principle involves collecting the infrared energy radiated by the object being measured through an optical system, converting it through photoelectric conversion and signal processing, and then displaying the temperature value. It boasts significant advantages such as fast response speed, no interference with the measured temperature field, and avoidance of sensor wear.
[0003] While existing technologies, such as the portable high-temperature radiation thermometer disclosed in Chinese patent CN201589661U, have solved the problems of high cost of consumables and slow response speed in traditional thermocouple temperature measurement, they still have significant shortcomings in practical applications. During operation, a high-temperature resistant ceramic tube needs to be manually inserted into molten metal (such as molten iron). Differences in insertion depth and angle between different operators can lead to inconsistent thermal equilibrium within the ceramic tube, thus affecting the accuracy of radiation temperature measurement. Furthermore, the continuously rising hot airflow from the surface of the molten metal poses a risk of burns to the operator's arms. These human-caused measurement deviations and safety hazards severely limit the effectiveness of the equipment in industrial settings. Utility Model Content
[0004] This utility model provides a portable high-temperature radiation thermometer, which solves the problem that existing portable high-temperature radiation thermometers rely on manual insertion of a high-temperature resistant ceramic tube for measurement, and the measurement data is easily deviated due to the different insertion depths and angles of the operators; at the same time, it solves the safety hazards such as burns to construction workers.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A portable high-temperature radiation thermometer includes: a thermometer body, a first connecting tube, a second connecting tube, a mounting assembly, and a high-temperature resistant ceramic tube; one end of the thermometer body is connected to one end of a signal line; the other end of the signal line is connected to a sensor probe; the thermometer body is connected to one end of the first connecting tube; the other end of the first connecting tube is connected to one end of the second connecting tube; the other end of the second connecting tube is connected to the mounting assembly; and the other end of the mounting assembly is connected to the high-temperature resistant ceramic tube.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0029] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification.

[0036] The third connecting pipe 401 is fixed to the second connecting shell 402 by a second limiting ring 405; the second connecting shell 402 is sleeved with the second hemispherical shell 305 and fixed by a second fixing bolt 404; the second connecting shell 402 is provided with a second telescopic groove 403; one end of the third connecting pipe 401 is provided with a second connector 406; the third connecting pipe 401 is fixedly connected to the fourth connecting pipe 407 through the second connector 406; one end of the fourth connecting pipe 407 is provided with a plurality of inserts 408 evenly distributed around its circumference; the inserts 408 are provided with a plurality of locking blocks 409.

[0038] The sensor probe 102 is disposed between the fourth connecting pipe 407 and the third connecting pipe 401.
[0039] The card blocks 409 are arranged linearly at intervals along the insert strip 408.

[0041] The working process of this utility model is as follows: First, adjust the angle between the second connecting pipe 3 and the first connecting pipe 2 according to the angle of the test area.

Adjust the angle between the third connecting pipe 401 and the second connecting pipe 3, and then rotate the second limiting ring 405 and the second fixing bolt 404 to fix the angle between the third connecting pipe 401 and the second connecting pipe 3. Adjust the tilt of the high-temperature resistant ceramic tube 5 into the molten iron to be tested as needed, so that the position of the thermometer body 1 is offset from the vertical top of the high-temperature resistant ceramic tube 5, leaving a safe angle in both the height and horizontal directions, thereby separating and forming a safe distance to prevent the operator's arm holding the handle from being burned by the heat emitted by the molten iron to be tested. The observation plate 502, which is slidably mounted on the high-temperature resistant ceramic tube 5, is slid to the position on the high-temperature resistant ceramic tube 5 where it needs to be inserted into the molten iron to be tested. The third fixing bolt 503 is then adjusted to fix the position of the observation plate 502. During the process of inserting the high-temperature resistant ceramic tube 5 into the molten iron to be tested, the observation plate 502 is observed. When the observation plate 502 is submerged in the molten iron, the insertion is stopped. This avoids changes in the depth or inclination of the high-temperature resistant ceramic tube 5 into the molten iron to be tested when different operators operate it, thereby ensuring the thermal balance of the cavity inside the high-temperature resistant ceramic tube 5, avoiding deviations in the test results, and thus improving the accuracy of the test.
