Description

Fire extinguishing device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a fire extinguishing device, in particular to a fire extinguishing device for extinguishing fire in high altitude.

[ background of the invention ]

Data statistics shows that about 4 thousands of fires occur in China every year, 2000 people die, 3000-4000 people are disabled, and direct property loss caused by the fires every year is more than 10 billion yuan. How to extinguish the fire quickly to reduce the loss of people and property is a very important thing.

High-rise fire has the characteristics of rapid spread of fire, difficult evacuation and great difficulty in fighting, and once fire catches, the high-rise fire is difficult to control and escape due to complex structure and dense personnel. The existing fire-fighting equipment in China is mainly a fire-fighting water tank truck, the water-spraying remote-shooting capacity of the fire-fighting water tank truck is only 8 floors high, the equipment for ascending rescue is mainly a fire-fighting aerial ladder truck, the height-lifting rescue capacity of the fire-fighting aerial ladder truck is about 50 meters, the fire-fighting aerial ladder truck is equivalent to fifteen floors of a high building, and the fire-fighting rescue equipment can only be 'sighing to the building' for a higher high-rise fire. Therefore, effective rescue and emergency escape of high-rise fire become social problems which are highly concerned by people, and the technical problem of emergency rescue of high-rise fire is urgently solved.

It is known that only a very small number of big cities such as Beijing, Guangzhou and the like in China are equipped with a very small number of ultrahigh fire-fighting facilities. For example, in 2013, although a 78-meter high-speed jet vehicle is used in a 12.15-inch fire in Guangzhou, the fire cannot enter a fire scene at one time due to the influence of traffic control, public inspection and the like, and the 78-meter high-speed jet vehicle is put into use in a late time after about seven to eight hours of fire.

The fire extinguishing modes currently used in China comprise: isolation method, suffocation method, cooling method and chemical inhibition fire extinguishing.

1. An isolation method: the place or object on fire is isolated or removed from the surrounding combustible material and combustion is stopped by the lack of combustible material. When the device is actually used, combustible, inflammable and combustion-supporting articles which can be close to a fire source are removed; moving the object on fire to a safe place; closing valves of combustible gas and liquid pipelines, reducing and stopping combustible materials from entering a combustion area and the like.

2. Asphyxia method: preventing air from flowing into the combustion area or diluting the air with non-combustible substances, so that the comburent can not obtain enough oxygen to extinguish.

3. And (4) cooling. Spraying a fire extinguishing agent directly onto the combustion products; to reduce the temperature of the combustion products. When the temperature of the combustion products drops below the ignition point of the products, combustion is stopped. Or the fire extinguishing agent is sprayed on the combustible matter near the fire source to prevent the fire from being affected by the radiation heat.

4. Chemical suppression fire extinguishing method: the chemical fire suppressant is injected into the combustion zone to participate in the chemical reaction of combustion, thereby stopping combustion.

None of the above four methods can solve the fire of the high building.

The isolation method is certainly impossible, and once used, it means to abandon the personnel in the area of fire, and at the same time, the building has a lot of combustible materials and cannot be completely isolated.

The suffocation method has a certain limitation when facing fire extinguishment of high buildings, and the method can reduce the oxygen content in a fire extinguishing area, so that people in the fire extinguishing area can be suffocated and die, and only buildings can be kept. Obviously, this method can only be used in some high buildings where people are not living, and cannot be used for extinguishing fires in residential buildings, but unfortunately, most fires occur in residential buildings.

Chemical suppression fire extinguishing is also difficult to achieve, mainly because: combustible substances in residential buildings are various in types, distribution positions are uncertain, and it is difficult to determine which chemical fire extinguishing agent is used at a certain position.

The cooling method is possible in principle, and the building is protected under the premise of maximally protecting the safety of the personnel in the fire-out area by reducing the temperature of the fire-out area so as to be lower than the ignition point of the combustible, but the method has fatal weakness. The fire extinguishing agent is sprayed into the fire area only by the fire truck, and the effective operation height of the fire truck is concentrated between 20 meters and 35 meters, which cannot meet the requirement of fire extinguishing in high buildings.

With the wide application of unmanned aerial vehicles in various fields, an unmanned aerial vehicle with 50kg of effective load is jointly developed by falcon fire-fighting science and technology limited company, shanghai fire-fighting institute of police department, policeman fire-fighting chief of south river, three companies of south river and aviation industry limited company for fire extinguishment, and the unmanned aerial vehicle can carry dry powder or water to operate and obtain better performance in tests. However, the observation and test items show that the fire site is only one bedroom, the range is small, and the unmanned aerial vehicle takes 30 seconds to extinguish the fire. However, if the fire site is two bedrooms, then the unmanned aerial vehicle is required to land for water injection and then fly for fire extinguishment in order to extinguish the fire according to the water yield of 40 liters per minute and the maximum payload of fifty liters. However, the fire can spread continuously while water is injected, and the fire scene facing unmanned planes after taking off can be larger than that of two bedrooms. This solution is difficult to implement in reality.

In view of the above technical problems, it is necessary to provide a solution for fire extinguishing in high buildings to solve the above technical problems.
