Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, and in particular relates to a mobile smoke exhaust device for fire fighting and rescue. Background Art

[0002] When a fire occurs, the first thing to do is to ensure the safe evacuation of people in the building, including guiding them to a safe place along a safe passage. The fire should be prevented from spreading as much as possible, including controlling the direction of the fire and the burning area to reduce the generation of smoke. When a fire occurs in a high-rise corridor or a household, firefighters will use various smoke exhaust equipment, such as smoke exhaust fans, smoke exhaust ducts, etc., to effectively remove the smoke in the building to keep the air fresh. The task of the smoke exhaust work is to ensure the safe evacuation of people in the building and effectively control the fire and smoke to reduce the damage and losses caused by the fire. The current exhaust fans require multiple people to carry them to different floors. When a fire occurs, due to the emergency environment, carrying the exhaust fan up and down the stairs is not only inefficient, but also labor-intensive. Therefore, the inventor proposes a mobile smoke exhaust device for fire rescue to meet the use needs. Utility Model Content
