Description

Intelligent fire protection system

This application claims priority from the application of the Chinese Patent Office on September 11, 2018, with the application number 201811055462.8, and the application name is "an intelligent fire protection system", the entire contents of which are incorporated herein by reference.

Technical field

The invention belongs to the field of fire safety and relates to an intelligent fire protection system.

Background technique

During the work of various transportation equipment, due to the aging of the line, the leakage of fuel oil and engine oil onto the high temperature pipe or the fire caused by artificial arson is mainly manifested in the following aspects:

(1) It is not easy to be detected and extinguished in time at the beginning of the fire, which causes the fire to intensify and spread;

(2) The fire extinguishers (dry powder fire extinguishers, carbon dioxide fire extinguishers, etc.) equipped with them have a limited capacity. When the fire is large, the fire extinguishers are not enough;

(3) In the event of a fire, most people cannot use the fire extinguisher correctly, or they cannot extinguish the fire due to factors such as panic;

(4) As the vehicle is traveling, the inert gas in the gas fire extinguisher escapes with the wind and cannot play the role of suffocating oxygen and extinguishing the fire;

(5) When the dry powder fire extinguisher is running with the vehicle for a long time, the fire extinguishing agent, "dry powder", is continuously deposited and solidified, and the spray effect of the dry powder is affected during use, which greatly reduces the fire extinguishing efficiency;

(6) Existing fire extinguishing agents have certain toxic and side effects and should not be used as cabin fire extinguishing;

(7) Inert gas can cause suffocation of personnel, and it should not be used as fire extinguishing in the cabin;

When a fire accident occurs in a high-rise building, if the fire cannot be extinguished in time, the losses will be huge. Although high-rise buildings are equipped with some fire-fighting equipment (such as water sprinkler devices and fixed fire hydrants, etc.), the time from the fire to the start of fire-fighting operations is relatively long. At this time, the fire has begun to expand and these fire-fighting equipment can no longer control the fire. Due to the needs of the environment and the "high" nature of high-rise buildings, it is difficult for external rescue to conduct timely fire fighting. In many fixed facilities and places, when a fire occurs, most people are left unattended or have a long time to arrive, resulting in untimely fire fighting and causing large losses. When a fire occurs in a family, most people are unable to take fire extinguishing measures because no one in the family or a person with disability can take measures, resulting in the spread of the fire and causing large property losses to the family.

Existing fire extinguishing systems such as water sprinkler fire extinguishing systems, water spray fire extinguishing systems, gas fire extinguishing systems, foam fire extinguishing systems, water mist fire extinguishing systems and aerosol fire extinguishing systems, as well as various fire extinguishers, need to be manually turned on or firefighters Hand-held fire extinguishers are used to extinguish a fire. The time interval from the fire alarm to the start of the fire is often long, and the best time to extinguish the fire in the early stage of the fire is lost.

Container valves are widely used in the field of fire fighting. Container valves are installed on various types of fire extinguishing devices such as water-based extinguishing devices, dry powder fire extinguishing devices, foam fire extinguishing devices, gas fire extinguishing devices, etc. There are four basic types of container valve opening methods: electric (electromagnetic), pneumatic, electric explosion and mechanical (manual). These types of opening methods are subject to certain limitations, such as: electric (electromagnetic) type consumes a lot of power The valve body is large; the pneumatic type requires high-pressure gas cylinders and pipes to communicate with the container valve to work, and the device is complex and large; the electric explosion type is prohibited by the national policy; the mechanical (manual) type requires manual operation Opening operations and complex institutions.
