Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring devices, in particular to a gas monitoring device. Background Art

[0002] In the prior art, a gas detection alarm is a gas leak detection alarm instrument. When flammable or toxic gas leaks in an industrial environment, when the gas detection alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas detection alarm will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.

[0003] After searching, the Chinese patent application number 202223526075.2 discloses a gas monitoring alarm device, including a gas monitoring alarm instrument body, a gas monitoring hole is arranged at the center position of the top surface of the gas monitoring alarm instrument body, a display screen is arranged near one side of the top surface of the gas monitoring alarm instrument body, and a sound-transmitting hole is arranged near the other side of the top surface of the gas monitoring alarm instrument body, a switch button is arranged near the bottom of the outer surface of the gas monitoring alarm instrument body, a fixing strap is arranged near the bottom of the outer surface of the gas monitoring alarm instrument body, and a protective buffer shell is arranged on the gas monitoring alarm instrument body, a plurality of evenly distributed rubber buffer gaskets are arranged on the outer surface of the gas monitoring alarm instrument body, and a plurality of evenly distributed buffer springs are fixed around the edge of the top surface of the gas monitoring alarm instrument body, and the top of the buffer spring is fixed to the inner wall of the protective buffer shell.

[0004] The above patent has the following shortcomings: the device can be worn on the arm of the worker through a fixed strap, so that it can move with the worker in the mine, so that the gas situation at the worker's location can be monitored in real time, thereby improving safety; however, in the actual use of the device, the power required for the operation of the entire device is relatively large, resulting in its overall size being relatively large. When miners work inside the mine, on the basis of ensuring their own safety, they should reduce the items they carry as much as possible to facilitate safe production. However, the overall structure of the device will affect the miners' production activities and is not conducive to the miners' work. Utility Model Content
