Description

Technical Field

[0001] The utility model relates to the technical field of production safety early warning, and more specifically, to a production safety early warning device. Background Art

[0002] Production safety early warning devices are mainly used to check and alarm for safety in the production environment. There are many types of them. The safety detection alarms taken are different depending on the working environment. Common ones are toxic gas alarms, which are widely used in chemical, petroleum, pharmaceutical, metallurgical, electric power and other industries, as well as laboratories, hospitals, underground mines and other places. In these places, toxic gases may be produced during the production process or released when an accident occurs, causing serious harm to personnel and equipment. The role of the toxic gas alarm is to detect the presence of toxic gases at the first time and issue a timely warning.

[0003] When installing existing toxic gas alarms, in order to prevent people from accidentally touching or being damaged by touching, they are usually installed at high places. During the use of toxic gas alarms, in order to ensure the normal operation of the equipment, its maintenance work is very important. Therefore, personnel need to regularly perform maintenance work on them. Because it is installed at a high place, every time personnel perform maintenance work on it, they need to climb to a high place to work, which poses a safety hazard and makes maintenance work inconvenient. In view of this, we propose a safety production early warning device. Utility Model Content
