Fire suppression method and system for vehicle at charging position

Abstract

The invention provides a fire suppression method and system for a vehicle at a charging position. The system comprises a fire detection device and a charging position automatic fire extinguishing device. The fire detection device comprises a detection controller. The charging position automatic fire extinguishing device comprises a fire extinguishing agent storage box, a centrifugal water pump, a water delivering pipeline and spray heads which are sequentially connected. The spray heads are arranged on at least two sides of the charging position. A water-based fire extinguishing agent is stored in the fire extinguishing agent storage box. The water delivering pipeline is connected with a municipal water pipeline through a three-way valve. The detection controller is connected with the centrifugal water pump. The fire detection device further comprises a smoke sensor, a temperature sensor and a gas sensor. The smoke sensor, the temperature sensor and the gas sensor are all connected with the detection controller. After the charging position automatic fire extinguishing device is started, a large amount of water-based fire extinguishing agent can be rapidly sprayed, a layer of thin water film can be formed and expanded on the surface of a combustible by the fire extinguishing agent, and the combustible is isolated from air.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a fire suppression method and a suppression system for a charging station vehicle. Background technique [0002] As the society has higher and higher requirements for environmental protection and energy saving, new energy vehicles are getting more and more attention from the government and automobile manufacturers. However, since new energy vehicles use batteries and motors as driving power sources, there are always some safety hazards in the actual use process. Especially in recent years, there is an explosive growth demand in the field of new energy vehicles and energy storage. The news of spontaneous combustion of electric vehicles is frequently seen in the newspapers, mainly because the liquid electrolyte of the ternary lithium battery is flammable and explosive, and it is easy to trigger " thermal runaway". From the perspective of working principle, the...

Problems solved by technology

Among them, the above-ground parking spaces and three-dimensional parking spaces usually do not have corresponding fire protection design, and although the underground parking spaces are equipped with sprinkler fire protection systems, conventional sprinkler fire protection systems usually spray a large area when a fire occurs, and cannot carry out targeted fire fighting vehicles. Therefore, the pertinence is low and the fire-fighting efficiency is low. Once a vehicle catches fire and cannot be isolated and extinguished in time, it is easy to ignite the surrounding vehicles at the same time, causing huge personal and property losses to manufacturers and consumers.
