A wedge cone is fixedly sleeved on the transmission shaft, and a second installation groove is opened on the outer circumference of the cylindrical base, and a hinged column is installed in the second installation groove, and the hinged column is hinged with the first The limit piece matched with the two installation grooves, the installation sleeve is provided with a first limit groove corresponding to the corresponding position of the second installation groove, and the cylindrical base is radially pierced with a push rod in the first limit groove for The problem of inconvenient disassembly of the fan blades of the existing fire-fighting smoke exhaust fan is solved.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a quick-detachable fire-fighting smoke exhaust fan. Background technique [0002] With the rapid development of the national economy, urban construction and personnel flow tend to be large-scale and dense. In order to alleviate the resulting space pressure, the construction of public areas and underground spaces has become a new theme of urban planning. In these areas, due to the large flow of people, compact space structure, and few entrances and exits, the air circulation is not smooth, especially when a fire occurs, the smoke generated is high in concentration and strong in toxicity. There is always the danger of suffocation in such a high temperature, toxic and severely hypoxic environment. Therefore, the forced evacuation of smoke must be carried out by relying on large-flow fire-fighting smoke exhaust fans. [0003] At present, the structure of the fire exhaust ...
