Automatic fire extinguishing device for cabin

Abstract

The invention provides an automatic fire extinguishing device for a cabin. The device comprises a signal collecting mechanism, a control mechanism, driving mechanisms, transmission mechanisms and a fire extinguishing mechanism, the signal collecting mechanism is electrically connected with the control mechanism, the control mechanism is electrically connected with the driving mechanisms, the driving mechanisms are mounted on the transmission mechanisms, and the fire extinguishing mechanism is mounted on the driving mechanisms; and every driving mechanism includes a motor, a driving shaft, a shaft coupling, a first bevel gear, a second bevel gear, a connecting shaft, a roller and a mounting bracket. The device greatly improves the sensitivity of the fire prediction in the cabin, and a temperature sensor collects the temperature signal in the cabin in time, so the device can timely detect the fire and extinguish the fire when the fire just occurs or can be extremely easily extinguished,thereby the hazard of the fire is greatly reduced.

Description

technical field [0001] The invention relates to the field of engine room fire extinguishing, in particular to an automatic fire extinguishing device for an engine room. Background technique [0002] With the large increase in the number of domestic civil aviation aircraft and the number of flights, the probability of fire safety hazards on the aircraft also increases. The reliability of the aircraft fire protection system is crucial to the safety performance of the aircraft, and its fire safety performance is particularly important. The interior of the aircraft cabin is a special environment. Considering the anti-corrosion requirements of aircraft on-board equipment, as well as restrictions such as aircraft load, traditional physical fire extinguishing methods and chemical fire extinguishing methods are not suitable here. Water mist fire extinguishing technology is used for fire extinguishing in special environments due to its non-corrosive, rapid fire extinguishing, low wat...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic automatic fire extinguishers are basically installed in fixed positions. Generally, multiple units need to be placed in a relatively large space or aisle. The probability of fire in the above occasions is very low, and the fire extinguishing materials in the fire extinguisher need to be replaced regularly. , resulting in a large waste
