Description

Technical Field

[0001] The present application relates to the technical field of thermometers, and in particular to an explosion-proof two-in-one ring laser infrared thermometer. Background Art

[0002] Infrared temperature measurement technology plays an important role in product quality control and monitoring, online equipment fault diagnosis and safety protection, and energy conservation during the production process. In the past 20 years, non-contact infrared human body thermometers have developed rapidly in technology, with continuous improvement in performance, enhancement of functions, increasing variety, and expanding scope of application. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use, and long service life. The explosion-proof two-in-one ring laser infrared thermometer is a type of thermometer, and its use environment is relatively harsh.

[0003] Since explosion-proof two-in-one ring laser infrared thermometers are often used in harsh environments with dangerous explosions, such as petroleum, chemical, pharmaceutical, oil depot, tank area and other dangerous places with flammable and explosive gases, it is necessary to ensure the stability of the thermometer. In order to ensure the accuracy of the measured results when the thermometer is used, the protection of the thermometer will be improved so that the thermometer can work stably, but this will lead to a decrease in the heat dissipation effect of the thermometer. Its laser transmitter generates heat when working. If the heat cannot be discharged in time, it will cause thermal failure. However, traditional air-cooled heat dissipation in harsh environments will cause a lot of dust and impurities to adhere to the transmitter. Utility Model Content

[0004] In order to improve the problem of poor heat dissipation efficiency of existing thermometers when working in harsh environments, the present application provides an explosion-proof two-in-one ring laser infrared thermometer.

[0006] By adopting the above structure, the electrical components in the thermometer can be protected by the explosion-proof casing. At the same time, the heat dissipation mechanism embedded in the explosion-proof casing can assist in the heat dissipation of the laser emitter in the thermometer. The cooperation between the heat conduction component and the exhaust component improves the heat dissipation efficiency of the laser emitter.

[0007] The heat-conducting component comprises a copper sleeve, and a circular opening for installing the copper sleeve is provided on an outer wall of one side of the heat-dissipating box.

[0008] With the above structure, the heat-conducting component can be conveniently installed inside the heat dissipation box through the arrangement of the copper sleeve.

[0018] With the above structure, the electric telescopic rod is set to facilitate driving the mesh plate 2 to slide on the surface of the mesh plate 1. When the mesh holes on the mesh plate 2 and the mesh plate 1 overlap, the air duct of the heat dissipation box is opened, and the spring is set to facilitate the sliding of the auxiliary mesh plate 2.

[0019] A protective head for protecting the laser transmitter is clamped at one end of the explosion-proof housing.

[0020] With the above structure, the sealing performance of the explosion-proof housing can be conveniently improved by setting the protective head.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. The present application embeds a heat dissipation mechanism in an explosion-proof casing, and cooperates between the heat-conducting component and the exhaust component in the heat dissipation mechanism to facilitate heat dissipation of the laser transmitter. At the same time, the relatively independent heat dissipation space in the heat dissipation box prevents dust and impurities from adhering to the transmitter during the heat dissipation process, thereby improving the heat dissipation efficiency of the laser transmitter and reducing its failure rate.

[0023] 2. The present application sets a heat-conducting component in the heat dissipation box. The cooperation between the copper sleeve and the heat sink in the heat-conducting component facilitates the heat transfer from the emitter to the heat sink, and then the heat on the heat sink is discharged through the exhaust component, thereby avoiding direct contact between the emitter and the cooled air.
