Description

Technical Field

[0001] This utility model belongs to the field of chemical safety management technology, and specifically relates to an alarm device for chemical safety management. Background Art

[0002] Petrochemical production processes are complex, involving high temperatures and pressures, and are continuous. Most of the materials are flammable, explosive, toxic, and hazardous chemicals. During the production, processing, storage, transportation, and use of petrochemicals, toxic and harmful gases are often generated. Therefore, strengthening the management and protection against toxic and harmful gases is of great practical significance in preventing acute poisoning.

[0003] In existing related technologies, because toxic and harmful gases spread slowly in the air after leakage, there is a time interval before they reach the alarm device, making it impossible to detect toxic and harmful gases in the air in a timely manner. Therefore, there is an urgent need to design an alarm device for chemical safety management to deal with these problems. Utility Model Content

[0024] In this embodiment: the auxiliary mechanism 2 includes fixed mounting components disposed on both sides of the base plate 1. A vertical plate 201 is mounted on the base plate 1, and a lifting and moving assembly is disposed on the vertical plate 201. A support platform 206 is disposed on the lifting and moving assembly, and a battery 207 is mounted on the lower end of the support platform 206. The fixed mounting components include a support mounting platform 200 disposed on the base plate 1, and a fixing hole 2001 is provided on the support mounting platform 200.

[0025] In this embodiment: the alarm execution mechanism 3 includes a housing 301 disposed above the auxiliary mechanism 2. Square boxes 302 are disposed on both sides of the housing 301. A movable top cover 303 is slidably disposed on the housing 301. A sealing material is disposed between the housing 301 and the movable top cover 303, ensuring a reliable airtight connection between the movable top cover 303 and the housing 301 when the housing is stationary. A grate 304 is installed on the square box 302. An intake fan 305 is disposed inside the square box 302, and an exhaust fan 3051 is disposed on one side of the intake fan 305. A power motor is installed at one end of both the intake fan 305 and the exhaust fan 3051. A detection component is disposed inside the housing 301, and an alarm component is disposed on the movable top cover 303. The detection component includes a gas detection module 306 disposed inside the housing 301. A data analysis module 3061 is disposed on one side of the gas detection module 306, and a catalytic combustion sensor 307 is disposed on the other side of the data analysis module 3061. The alarm assembly includes a movable platform 309 mounted on a movable top cover 303, an alarm light 310 installed on the movable platform 309, and an alarm 308 installed on one side of the alarm light 310. A display is installed on the front of the enclosure 301 for displaying detection data. The data analysis module 3061, gas detection module 306, and catalytic combustion sensor 307 are existing technologies and will not be described in detail here. The gas detection module 306 detects the air inside the enclosure 301. When toxic or harmful gases are detected, the detection information is transmitted to the data analysis module 3061 and the catalytic combustion sensor 307. The data analysis module 3061 and the catalytic combustion sensor 307 work together to transmit the analyzed data to the display. The catalytic combustion sensor 307 uses the Wheatstone bridge principle. The sensing resistor undergoes flameless combustion with the combustible gas in the environment, causing a change in the resistance of the sensing resistor due to temperature, breaking the bridge balance, and outputting a stable current signal. After amplification, stabilization, and processing by subsequent circuitry, a reliable value is finally displayed. The alarm light 310 and the movable top cover 303 are connected by mounting holes and positioning pins on the movable platform 309, so that the alarm light 310 can be disassembled, replaced and repaired from the movable top cover 303.

[0026] Working Principle: In use, the base plate 1 is first installed on the wall at the corresponding position using the set support mounting platform 200, fixing holes 2001, and connecting screws. The lifting and moving assembly is activated to move the housing 301 up and down, allowing it to contact the air at different positions. At the same time, the power motor is turned on to drive the intake fan 305 to rotate forward, drawing the air around the device into the housing 301 through the grate 304. With the help of the data analysis module 3061, the gas detection module 306, and the catalytic combustion sensor 307, the content of toxic gases in the air can be detected, and the detected data is sent to the display screen, allowing workers to more intuitively understand the content of toxic gases. When the toxic content in the air exceeds the standard, the alarm 308 will emit a piercing sound, and the alarm light 310 will flash, which can promptly remind workers to evacuate. At the same time as detection, the power motor is activated to drive the exhaust fan 3051 to rotate in reverse, extracting the harmful gases from the housing 301 to prevent poisoning incidents.
