Description

Technical Field

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

[0002] A gas alarm is a gas leak detection and alarm device. When gas leaks in an industrial environment and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas alarm will issue an alarm signal. To ensure safety in daily production and life, gas alarms must be regularly inspected annually to ensure they are functioning properly. However, due to the varying installation locations of gas alarms depending on the terrain, some alarms are located high up, making them difficult for maintenance personnel to reach, making inspection and maintenance time-consuming and labor-intensive. Publication No. CN218824208U discloses a gas alarm detection device, which relates to the field of gas alarm detection technology. The device comprises a detection cover, each of which has a vent hole formed on either side. A venting device is fixedly connected to a pipe connected through one of the vent holes, and a ventilation detection device is fixedly connected to the inner wall of the other vent hole. The device prepares a predetermined gas cylinder, injects gas of a predetermined concentration into the cylinder, and creates a certain vacuum inside the detection cover through the venting device. A certain amount of gas is then injected into the detection cover to restore the air pressure inside the detection cover to a normal state, at which point the gas concentration inside the detection cover is very close to the predetermined gas concentration in the cylinder. However, this detection device is difficult to apply to gas alarms located at higher positions. Utility Model Content
