Description
Technical Field
The invention relates to the technical field of fire fighting, in particular to a novel combined type spraying fire extinguishing system.
Background
A fire refers to a disaster caused by combustion that is out of control in time or space. In the new standard, fire is defined as combustion that is out of control in time or space. Among the various disasters, fire is one of the main disasters that threaten public safety and social development most often and most generally. For fire, in ancient China, people summarized the experience of 'preventing the fire for the first time, rescuing the fire for the second time and giving up the fire for the next time'. With the continuous development of society, the social wealth is increasing, meanwhile, the danger of fire disasters is also increasing, and the hazard of the fire disasters is also increasing. According to statistics, the average fire loss in 70 years is less than 2.5 million yuan, and the average fire loss in 80 years is less than 3.2 million yuan. Since the 90 s, especially 1993, the direct loss of property from a fire has risen to billions of yuan per year, with 2000 deaths per year. Practice proves that along with the development of society and economy, the importance of fire fighting work is more and more prominent. "preventing and reducing the risk of fire" is a general summary of the legislative meaning of fire control, including two layers: firstly, various work for preventing fire is well done to prevent the fire from happening; secondly, fire is absolutely impossible, and once the fire breaks out, the fire should be suppressed timely and effectively, so that the harm of the fire is reduced. Fire control is to eliminate hidden troubles and prevent disasters (i.e. to prevent and solve human, natural and accidental disasters in the life, work and learning process of people), and certainly the narrow meaning in the early stage of people understanding is: meaning (extinguishing) fire. For the indoor fire-fighting field, at present, a spray fire-extinguishing system and an automatic tracking and positioning jet fire-extinguishing device (called an automatic fire monitor for short) are widely used at home and abroad. The spraying fire extinguishing system and the automatic fire monitor cannot be remotely communicated to control fire extinguishing, the spraying fire extinguishing system needs to automatically spray water, manually closes a valve to cut off water, and performs centralized control in the fire extinguishing process, so that the system is self-formed and self-closed, the spraying fire extinguishing system can cause 'flood irrigation' although the coverage is wide, and water resources are wasted. The automatic fire monitor adopts the mode of automatic fire extinguishing and field control panel control to extinguish fire, only supports linkage alarm and image transmission when extinguishing fire, has high difficulty in extracting flame detection signal characteristics in a large space, low signal-to-noise ratio and easy generation of misjudgment and missed judgment, and the water outlet of the automatic fire monitor is integrated with the detection part, so that the problem that water flow cannot bypass obstacles to accurately extinguish fire due to the falling of the water flow under the action of gravity is considered. In order to overcome the above problems, we propose a new combined sprinkler system.
