Description

Technical Field

[0001] This utility model relates to the field of infrared gas sensor technology, and more specifically, to an explosion-proof infrared gas sensor. Background Technology

[0002] Explosion-proof infrared gas sensors are devices specifically designed to detect the concentration of specific gases in an environment, and they can be used safely in potentially explosive atmospheres. These sensors are commonly used in industrial locations such as chemical plants, oil and gas facilities, and mining operations, where flammable gases or vapors may be present. Explosion-proof infrared gas sensors work by detecting the presence of gases using infrared (IR) technology. They typically consist of a light source (usually an infrared LED or bulb), a measuring chamber, and a detector. When the gas to be measured enters the measuring chamber, it absorbs infrared light of a specific wavelength. The detector detects this absorption and converts it into an electrical signal, which is then processed by electronic circuitry to determine the gas concentration.

[0003] To ensure high-precision detection results, infrared gas sensors are equipped with sophisticated optical components. However, these components are very fragile; they may shift or even be damaged by impacts or vibrations, directly affecting the accuracy and reliability of the detection. Furthermore, infrared gas sensors are susceptible to humid environments during use; excessive humidity can cause internal components to become damp, thus affecting the sensor's performance and lifespan. Currently, no effective solutions have been proposed to address these technical issues. Utility Model Content

[0004] In view of the problems in related technologies, this utility model proposes an explosion-proof infrared gas sensor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An explosion-proof infrared gas sensor includes a sensor body, an air inlet at one end of the sensor body, a connector at the rear of the sensor body, and a shock-absorbing mechanism on the outside of the sensor body.

[0007] Furthermore, in order to enhance the protection of the sensor body, the shock absorption mechanism includes two mounting plates on the sensor body, a protective plate between the two mounting plates, and a telescopic spring at the bottom of the protective plate.

[0008] Furthermore, one end of the telescopic spring is connected to the protective plate, and the other end is connected to the connecting plate. Both ends of the connecting plate are connected to the mounting plate, and a dehumidification mechanism is provided on one side of the mounting plate.

[0009] Further, in order to be able to absorb the moisture around the sensor body, prevent moisture from entering the sensor interior, and cause damage to the electrical elements inside the sensor, the dehumidification mechanism includes a drying box arranged on one side of the mounting plate, the number of drying boxes is two, drying particles are arranged in the drying box, a through hole is arranged on the drying box, a groove is arranged on the mounting plate, and the groove is matched with the drying box.

[0010] Further, in order to facilitate the replacement of the drying particles inside the drying box, sealing covers are detachably connected to both ends of the drying box.

[0011] Further, in order to facilitate the disassembly of the drying box, fixing plates are connected to both sides of the drying box, mounting holes are arranged on the fixing plates, bolts are arranged in the mounting holes, threaded holes are arranged on the fixing plates, and the bolts are matched with the threaded holes.

[0012] Further, the number of protective plates is two, and the shape of the protective plates is arc-shaped.

[0013] The beneficial effects of the utility model are:

[0014] (1), by setting the protective plate and the extension spring outside the sensor body, the protective plate can provide effective protection when the sensor body is subjected to external physical impact, and the extension spring can absorb impact energy through elastic deformation when the sensor body is subjected to extrusion or vibration, thereby reducing the direct force on the sensor body. In industrial environments, sensors may be accidentally subjected to collisions or falls, which may cause damage to the internal precision components of the sensor, thereby affecting its detection performance and reliability. The use of protective plates can greatly reduce this risk and ensure that the sensor can maintain its functional integrity even in harsh conditions.

[0015] (2), by setting the dehumidification mechanism, the drying particles can absorb the moisture around the sensor body, prevent moisture from entering the interior of the sensor body, and cause damage to the internal components of the sensor, maintain the dryness of the working environment of the sensor, and when the drying particles fail, the drying box can be disassembled by disassembling the bolts, and then the failed drying particles can be removed and new drying particles can be refilled. After replacement, the drying box is reinstalled on the sensor body, and the bolts are tightened. In addition, the setting of the dehumidification mechanism helps to improve the explosion-proof performance of the sensor, because in some cases, high humidity may cause dangerous chemical reactions or electrical short circuits, and the presence of drying particles can effectively prevent such situations from occurring.
