Double-key-start fire extinguishing system capable of preventing automatic mist spray and used for bus passenger compartment

Abstract

The invention relates to a double-key-start fire extinguishing system capable of preventing automatic mist spray and used for a bus passenger compartment. The double-key-start fire extinguishing system capable of preventing automatic mist spray and used for the bus passenger compartment is characterized by comprising a plurality of agent storage modules used for storing a fire extinguishing agent,at least one gas storage module used for storing pressure gas, a conveying module connecting the gas storage module with the agent storage modules, controlled to be turned on and turned off through acentral control module, and capable of conveying the pressure gas in the gas storage module into the agent storage modules, and at least two start buttons used for controlling the central control module to be started and stopped, wherein the conveying module comprises a plurality of connection pipes connecting the agent storage modules with the gas storage module, and at least two first electromagnetic valves installed on the connection pipes, used for controlling the connection pipes to be opened or closed, and controlled through the central control module. The double-key-start fire extinguishing system capable of preventing automatic mist spray and used for the bus passenger compartment has the beneficial effects of being stable in use, and good in fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of bus fire extinguishing and fire protection, in particular to a double-button start-up fire extinguishing system for a bus cabin that prevents automatic spraying. Background technique [0002] With the improvement of living standards, the total number of cars and buses in China has increased year by year, and the proportion of buses in the total number of passenger vehicles has increased from 23% in 2009 to 60% in 2013. Due to the increasing number of buses , the probability of fires also increases accordingly. At present, in order to prevent fires on buses and stop them in time, people usually install fire extinguishing systems on buses to achieve the purpose of timely fire protection and prevent the fire from spreading. , however, the existing fire extinguishing system is extremely sensitive. When detecting a small amount of "fire information" or frequent vibration of the car, the fire extinguishing syst...

[0002] With the improvement of living standards, the total number of cars and buses in China has increased year by year, and the proportion of buses in the total number of passenger vehicles has increased from 23% in 2009 to 60% in 2013. Due to the increasing number of buses , the probability of fires also increases accordingly. At present, in order to prevent fires on buses and stop them in time, people usually install fire extinguishing systems on buses to achieve the purpose of timely fire protection and prevent the fire from spreading. , however, the existing fire extinguishing system is extremely sensitive. When detecting a small amount of "fire information" or frequent vibration of the car, the fire extinguishing system will also work. Therefore, most of the existing fire extinguishing systems are passively activated and cannot be actively controlled. Therefore, There is the possibility of instability; secondly, the fire extinguishing agent ejection principle in the existing bus fire extinguishing system is: a fire extinguishing agent storage tank is controlled by a gas storage cylinder, and the gas in the gas storage cylinder is often sufficient. And when the fire is severe, the fire extinguishing dose and the spray rate in a fire extinguishing agent storage tank cannot effectively extinguish the fire. If you want to increase the fire extinguishing agent storage tank and the gas storage bottle at the same time, it will inevitably cause a large occupation space and make the passenger car load too heavy. As a result, the energy consumption and loss of passenger cars increase
