Liquid filling type portable intelligent multi-direction jetting spherical fire extinguishing device

Abstract

The invention relates to a liquid filling type portable intelligent multi-direction jetting spherical fire extinguishing device and belongs to the technical field of fire protection and fire extinguishing machinery. The liquid filling type portable intelligent multi-direction jetting spherical fire extinguishing device comprises a spherical shell, intelligent trigger controllers, a perfluoro-hexanone fire extinguishing agent and a gas generating agent. The spherical shell is uniformly provided with telescopic jetting devices, and jet orifices of the telescopic jetting devices are sealed through aluminum foil. The intelligent trigger controllers are mounted on the outer portions of the telescopic jetting devices on the spherical shell. Each intelligent trigger controller comprises a fire detection sensor and a microcontrol chip connected with the fire detection sensor. The microcontrol chips judge whether a fire occurs or not according to signals transmitted from the fire detection sensors. The gas generating agent is located at the sphere center position of the spherical shell. The spherical shell is filled with the perfluoro-hexanone fire extinguishing agent. The perfluoro-hexanone fire extinguishing agent is isolated from the gas generating agent. The microcontrol chips of the intelligent trigger controllers are connected to the gas generating agent through electric ignitionwires. When judging that the fire occurs, the microcontrol chips trigger the electric ignition wires to ignite the gas generating agent. The liquid filling type portable intelligent multi-direction jetting spherical fire extinguishing device conducts fire extinguishing in a total flooding heat absorbing physical manner and is intelligent, safe, friendly to environment, convenient to use and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a spherical fire extinguishing device which uses a gas generating agent to spray perfluorohexanone fire extinguishing agent in multiple directions to achieve intelligent, safe, environmentally friendly, convenient and efficient fire extinguishing. Background technique [0002] With the rapid development of human society and the continuous expansion of cities, the risk of fire is increasing. The occurrence of fire not only caused a lot of wealth loss, but also posed a great threat to human life. In order to reduce the destructive effect of fire on human society and nature, it is very important to develop effective fire extinguishing products. [0003] 1. At present, most of the widely used fire extinguishers use high-pressure gas as the power to drive the fire extinguishing agent, and the pressure container has certain dangers. Therefore, there are certain safety hazards in...

Problems solved by technology

[0004] 2. Currently widely used fire extinguishing agent products, the halon fire extinguishing agent used in halon fire extinguishing agent will destroy the ozone layer and has been banned worldwide; dry powder fire extinguishing agent will cause secondary pollution; aerosol fire extinguishing technology has certain risks, High technical requirements; fine water mist fire extinguishing technology is difficult to extinguish and block the fire; inert gas fire extinguishing agent is not easy to store, and the cost is high; foam fire extinguishing agent is expensive and has a short storage period, and the fire resistance of aqueous film-forming foam is not strong

In several commonly used halon substitutes such as pentafluoroethane (HFC-125), bromofluoropropene (BTP), hexafluoropropane (HFC-236fa), heptafluoropropane (HFC-227ea) and other substances, the greenhouse effect potential value is high , The atmospheric time is kept for a long time, it is not safe to use in places with people, and it is not suitable as a fire extinguishing agent for long-term use

[0005] 3. The fire extinguishing equipment used on the market is mainly fixed, semi-fixed or mobile. These fire extinguishing equipment need to be manually moved to the fire extinguishing site when extinguishing a fire. Only when they are close to the fire source can the fire extinguishing effect be guaranteed, which has a great impact on the safety of firefighters. It is a big threat, and the fire extinguishing will be limited by the space and it will be inconvenient to operate

However, the existing spherical fire extinguishing devices still have certain deficiencies: (1) most of the existing spherical fire extinguishing devices have a single injection port, and the injection port may not be directly on the fire point when extinguishing the fire, which greatly reduces the fire extinguishing efficiency; (2) the current There are spherical fire extinguishing devices that use detonators, explosives and other detonation methods to spray fire extinguishing agents to achieve fire extinguishing effects. During use, they will cause harm to the surrounding environment and human body, and the safety hazard is large and inconvenient for transportation and storage; (3) existing The triggering of the spherical fire extinguishing device is mainly the active triggering and passive triggering methods based on the principle of delay and impact triggering. Both triggering methods have shortcomings: the delay triggering device will spray fire extinguishing agent in advance or lag behind the best explosion area, Extinguishing agent cannot provide effective coverage
