Therefore, idle waste of equipment resources such as a smoke exhaust fan, a civil air defense fan and the like is avoided, natural damage caused by long-term idle is avoided, the equipment cannot be used when the equipment is really needed, daily maintenance and management of civil air defense engineering are facilitated, and the area of a machine room can be saved.
Description
Technical Field
The utility model belongs to the technical field of fans, and particularly relates to a peacetime and wartime combined fan.
Background
At present, each large-scale personnel intensive building is required to be provided with a ventilation pipeline system and a fire-fighting pipeline system, and a civil air defense ventilation and toxicity-filtering pipeline system is required to be arranged in consideration of the personal safety factor in wartime. These systems take up significant building space and also bring increased operating costs to ordinary maintenance management. In addition, fire extinguishing system and people's air defense system are idle at ordinary times, cause certain waste, still sometimes because of long-term idle natural damage, can't use when needing to move on the contrary.
SUMMERY OF THE UTILITY MODEL
The utility model provides a peacetime and wartime combined fan which can solve the problems pointed out in the background technology.
A peacetime and wartime combined fan comprises a civil air defense fan and a fire fighting fan; the civil air defense fan and the fire fighting fan are driven to rotate through the driving motor, the civil air defense fan and the fire fighting fan are arranged in the same shell, and a civil air inlet, a civil air outlet, a fire fighting smoke inlet and a fire fighting smoke outlet are correspondingly arranged on the shell respectively.
Preferably, the civil air defense fan and the fire fighting fan are both centrifugal fans.
Preferably, the driving motor is a variable frequency motor.
Preferably, the driving motor is a double-extension-shaft variable frequency motor, and two ends of the double-extension-shaft variable frequency motor respectively drive the civil air defense fan and the fire fighting fan to rotate through a transmission belt.
Preferably, the two ends of the double-extension-shaft variable frequency motor respectively drive the civil air defense fan and the fire fighting fan to rotate through the shaft couplings.
Has the advantages that: the fire-fighting smoke exhaust fan and the civil air defense fan are combined together, so that the system can be ventilated in peace period, and the system is used for fire-fighting smoke exhaust when a fire disaster occurs; in the war period, the ventilation and poison filtration functions are achieved. Therefore, idle waste of equipment resources such as a smoke exhaust fan, a civil air defense fan and the like is avoided, natural damage caused by long-term idle is avoided, the equipment cannot be used when the equipment is really needed, daily maintenance and management of civil air defense engineering are facilitated, and the area of a machine room can be saved.
