Description

Technical Field

[0001] The utility model relates to a magnetic gas detection alarm device with a wireless transmission function, belonging to the technical field of gas detection. Background Art

[0002] The gas detection environment involved in the petroleum, chemical, smelting, pharmaceutical, municipal and other industries is often complex, such as the inability to provide power, installation brackets, and wired transmission methods. Take gas stations as an example. During the management of gas stations, it is expressly forbidden to make phone calls. However, since code scanning payment is very common, many gas stations in many places are equipped with code scanning payment for self-service refueling to meet the convenience of customers, which leads to certain safety hazards in gas stations and surrounding areas. The storage materials in the gas station's gas station and storage tank area are mainly flammable and combustible liquids such as oil and liquefied gas. Gasoline itself is a volatile substance. During the refueling process, gasoline is easy to volatilize, forming a flammable danger zone. Using mobile phone code scanning and other operations in this area will generate electromagnetic waves. If the radio frequency current touches the metal conductor, it will form a radio frequency spark, which will ignite the radio frequency molecules in the air to form an explosion.

[0003] The infrastructure of industries such as petroleum, chemical, smelting, pharmaceutical, and municipal administration has been built and operated for many years. Installing or adding wired gas detection devices requires digging pits, burying pipes, threading, and installation, which is time-consuming and labor-intensive, increasing operating costs. In addition, the fixed gas detection meters used in the prior art can only be fixed in a certain position and cannot be moved and installed, which will lead to inaccurate detection of leaked gas concentrations, and failure to provide timely warnings and alarms, thus causing explosion hazards. In addition, the fixed gas detection meters use an external power cord to supply power, which also poses the risk of sparks in dangerous areas. At the same time, the historical gas concentration information and alarm information detected cannot be stored and viewed in real time, and statistics and analysis of detection data cannot be formed.

With such a design, when the alarm device is fixedly adsorbed on the required structure by the magnet 9, the front end of the spring pin 15 is set on the contact of the anti-theft switch 8. When the alarm device is removed from the mounting structure, the spring pin 15 is ejected by the contact of the anti-theft switch 8 and slides backward, and then detaches from the contact of the anti-theft switch 8, triggering the alarm, and transmitting the alarm signal to the alarm light 5 and the speaker 6, and notifying the staff through the sound and light alarm.
